Life is nothing less than a hell without any entertainment in it. Thanks to mobile phones that let us entertain ourselves on the go. Mobile phones that are being launched nowadays, come with super impressive features that revolve around entertainment. Mobile manufacturers know it pretty well that entertainment has become an indispensable part of human life in the current era. This is the reason why mobile phones are nothing but a complete portable entertainment package. The main source of portable entertainment is music. A very common but irritating problem faced by the youngsters of this era is missing their favorite beat, or pausing a song frequently while conversing with someone. This seems to be negligible, but irritates most as they have to rewind the song or even restart it from beginning for the single beat. So think about a system that stops playing when the buds are taken off, and automatically continues when it is placed back. This seems to be simple but it is not so. This will change the whole experience of enjoying media, making a new mile stone in the entertainment world. This system will bring a new generation of media players that not only allows us to listen to our favorite music whenever we want but also allows automatic access without having to unlock our phones every now and then for the same.

The Tamil Nadu – Sri Lanka maritime boundary has been responsible for frequent controversies in the global front, due to fishermen from Rameshwaram and Ramanthapuram districts recklessly straying past Indian waters. Instances of Indian fishermen being captured and killed by the Sri Lankan navy have spun vivid images of violence and human rights violation among the masses. Social activists are desperate for an automatic alarm system to warn the fishermen when they are about to cross the border, and avert a possible impending crisis. The following discussion focuses on the design of an alarm signal system that could alert the fishermen on a periodic basis as they approach closer to the maritime boundary. Installing Global Positioning System (GPS) devices would pose several economic challenges. Instead of the conventional approach of using GPS devices to track location, a transmitter – receiver system exquisitely designed to send signals to the boat would be effective. This system helps in keeping a continuous track of the boats. It provides a reliable solution to alert fishermen before they could inadvertently exceed the boundary. © 2017 Institute of Advanced Engineering and Science. All rights reserved.

B. Sri Datta, Ganapathy, R., Sini Raj P., Dr. Shriram K Vasudevan, and SN, A., “An Inventive and Innovative Alternate for Legacy Chain Pulling System through Internet of Things”, Indonesian Journal of Electrical Engineering and Computer Science, vol. 6, no. 3, p. pp. 688 ~ 694, 2017.[Abstract]


Indian Railways made a move in replacing the chain pulling system with the new mobile based communication system where the loco pilot’s mobile phone number shall be shared with all the passengers through a message. Despite the efforts taken to remove the chains from the train, there is a great probability of misuse through the mobile phone number provided. We aim to build a more efficient and secure solution based on the Internet of Things, which is a buzz word in the market. Our proposed system provides an alarm fixed at specific locations in the compartments of a train. In case of emergency, the passenger has to press the alarms’ button, which captures the scene using a built-in digital camera. The system also alarms the Loco-Pilot, Travelling Ticket Examiner, as well as the compartment so as to provide immediate possible help through the fellow co-passengers. The pilot slows down the train to an optimum speed whilst the travelling ticket examiner checks and confirms the pilot whether he has to stop the train. The entire system can be controlled through an authenticated mobile application provided to the ticket examiner. The pictures captured by the camera and other crucial details are uploaded to a cloud-based real-time database. Thus, saving time and taxpayers’ money as well as helping the railways to perform analytics and come up with feasible solutions to the problems of the passengers. The system has the potential to deal with the most prevailing cargo theft like that of coal, by alerting the staff without having to stop the train, making the convicts’ escapes impossible. This also definitely avoids the improper pulling of chains and thereby not causing any hassle to the passengers as well as diminishes the economic loss to the government by reducing the time delay.

Before building any electronics product or equipment it is well known that, the person building it will finalize the circuit after lot of simulation with simulation tools or relevant coding with electronics coding packages. One needs to be conversant with simulation tools for electronics or coding or both. It is not only complex, it is also time consuming. We have come up with an innovative and effective solution for the above said problem. Here, with our proposed solution, one can draw the circuit that is being thought of in a paper. The image can be fed into our product (application) which will generate net list for the drawn circuit. This will make the life easier and save a lot of time. One can test a lot of combinations of the components of the circuit without having necessity to spend time with simulation or coding. In the past, the inventions related to this area have identified only RLC components. We have enhanced the quality and results with identification of more components, using machine learning and image processing techniques. Usage of machine learning has not only fetched good results but also it increased the chances of identifying more components with ease and accuracy. More »»

To come up with an effective load balancing algorithm in cloud environment which provides sharing the available resources systematically across the network. In this research, an optimized dynamic algorithm is proposed where it makes use of the concept of Honeybee algorithm which is categorized under the dynamic load balancing category. The proposed algorithm provides better makespan which is one of the main features in load balancing.The proposed algorithm is simulated using two simulators namely cloudsim and workflow. Somewhere, it compares both the dependent as well as independent nature of tasks. The main goal of load balancing algorithms in clouds is to reduce the makespan. Here, the algorithm performs with a reduced makespan for both type of tasks. Due to the heterogeneity behaviour of cloud, dynamic algorithms work better when compared to the static methods. The proposed algorithm is dynamic in nature and provides reduced makespan and it uses the resources efficiently. Our future research is based on proposing algorithm considering the other QS factorsof load balancing for both in dependent and independent nature of tasks. More »»

Autism Spectrum Disorder (ASD) is defined as a condition or disorder that begins in childhood and that causes problems in establishing relationships and communicating with other people. Aarya works as a personal well-being companion to children with Autism Spectrum Disorder while they interact with a virtual environment that is gesture based. By making an ASD affected child face real world situations, we try to improve his/her confidence in facing the world and being open to learning various skills. Social interaction and communication are the major challenges faced by children with ASD. In Aarya, we use gesture-based interface that is the Microsoft Kinect so that the child can find it easier to interact in the real world environment. Through the interactions made with the children and the results obtained, we understand that this tool can be a companion while giving chance for growth and improving their interacting ability. With further refinement and expert inputs, this tool can be built better. © 2017-IOS Press and the authors. All rights reserved.

R. B. Sundaram, Dr. Shriram K Vasudevan, Aravind, E., Karthick, G., and Harithaa, S., “Smart car design using RFID”, Indian Journal of Science and Technology, vol. 8, 2015.[Abstract]


Background/Objective: The Indian automobile market has seen a drastic change in its trends over the past decade with several road commuters opting for mid-range sedans and SUVs, owing to the safety features of cars that two-wheelers can never provide. At times, the driver is not fully aware of his surroundings, leading to inconveniences and compromises on safety. Methods/Statistical Analysis: This problem has several facets to it. Blocked vision due to a large vehicle in front is a major hassle that persists especially during heavy traffic, in turnings and in narrow lanes. Bright headlights at night cause discomfort and troubled vision to drivers. It is the worst nightmare of a "fuel-conscious" driver to get caught in a traffic jam when he could have chosen a different lane and or to be forced to return back due to blocked roads. The most frustrating experience for any driver would be to get stuck under the sweltering sun in a road either due to a flat tire or an empty fuel tank. Result/Findings: These issues could be solved if the driver is given constant inputs about vehicles near him and the fuel level, battery conditions and tire pressure status. Providing information from other vehicles could be facilitated through vehicle-to-vehicle communication. Conclusion/Application: These applications can be incorporated into the future self-driving cars. This application also increases the safety of the drivers thereby decreasing the road accidents.

S. Athira, Gopal, S., Krishna, G. H. G., and Dr. Shriram K Vasudevan, “An innovative and effective approach for sclera detection”, Indian Journal of Science and Technology, vol. 8, 2015.[Abstract]


Background/Objectives: Providing security to systems is one of the major challenges faced in day-to-day life. Biometrics plays a vital role in ensuring security. Out of the different existing recognition systems available - namely face, finger, gait, retina and so on, sclera recognition system gives out better performance. Sclera is the white part of the eye, which is unique and consistent in nature because of which it is chosen for recognition. In this paper, we analyzed the existing sclera recognition system with both human and animal eye images. Methods/Statistical Analysis: In this paper, we compared the performance of the algorithm with both human and animal eye images. The animals we considered for the algorithm analysis include deer, buffalo and lion. Human eyes are the most observable due to the presence of more sclera area. The blood vessel patterns present in the sclera region are stable over lifetime and unique person by person, thus making it appropriate for identification. The results show that the algorithm works better for human eye. Results/Findings: In this paper, we compared the extracted input vessel structure with that in the database and verify whether the input is authorized or not. It is observed that the system underperforms for animal eye images, whereas it shows an acceptable performance with human eye images. Conclusion/Application: The results prove that the algorithm works satisfactorily for identifying human. It can be incorporated with other recognition systems to build up a multimodal biometric system that can provide better security than the existing systems.

Crimes in the modern world have been increasing dramatically in proportion with technological growth. In many situations, investigators have a sketch of the criminal, generated from the details given by the eye witnesses. There is a need of a better methodology for identifying the culprits from those images. Nowadays, RAM and memory sizes have become huge and in turn, there is a tremendous increase in the size of the databases. Investigators have huge datasets with details, photographs, images of the criminals or crime scenes and this is the second important consideration. Image search has become highly challenging task in these dense database environments. Accuracy and speed are two important factors for this type of image searches. We propose a compact embedded search engine to search and extract images from these data bases, using a content-based image retrieval (CBIR) algorithm.

Objective: This research aims at formulating a method to categorise a given class of objects by obtaining a weighted matrix computed as explained below. Methods/Analysis: The method deployed can be branched into two phases: Training and Testing. In the first phase, a set of images of the concerned objects are taken. By set of images, one can refer to images of different objects, or different positions of the same object. The features are then, extracted for these input images and stored in the database as vectors. Any computation hence forth, is performed using these vectors. In testing stage, the algorithm uses its knowledge to identify the input image to a specified class. Findings: Our method is computationally inexpensive since all the calculations are performed on the basic grounds of matrix operations. This method is not just limited to the domain of object recognition alone. Any real-time entity that can be statistically represented in a vector form can be deployed. All that is required of the application is that the range of vectors is defined so as to obtain the minimum components and maximum components, individually. Once this is obtained, the algorithm will be sufficient to identify any input and will accordingly determine the category to which it belongs. The only challenge identified is that the range of vectors obtained from the input data for various categories must not overlap. That being the case will result in multiple hits or in simpler words, will give an incorrect result. Further work can be implemented on how to make the algorithm independent of this dependency. Also, the algorithm improves the results through various illumination and scaling conditions and this has been discussed in results and analysis section. Even with the existing methods to recognize an object, this algorithm can be combined to categorize or classify objects. Conclusion/Application: The proposed algorithm successfully classifies the input image into one of the trained categories by identifying the features followed by computing these obtained features as prescribed the given algorithm.

Objective: The idea is to upload files into cloud using gestures. A “Gesture” is a form of movement of part of a body, especially the hand or the head, to express an action. Waving of the hand over the phone is used as a gesture to export files into the cloud. Methods/Analysis: The type of the file to be uploaded into the cloud can be either a picture or a video. This is accomplished using an application similar to gallery. To perform the task, the application is invoked to view a picture or video, when the hand is waved over the phone. The gesture is recognized and the currently viewed file is uploaded into the cloud. The cloud service used here for uploading is Dropbox. The size of the media files is generally large and uploading it will take time, so the size is reduced through a compression algorithm. There is a buffer which tracks the uploading part and will see to that, that the entire media file is uploaded into the cloud. Findings: Through this application the file can be uploaded into the cloud through a gesture easily and effectively. Also, it is found that the application developed is found to be stable in tough testing conditions. Application/Improvements: This app reduces the human effort to a large scale and most importantly it does not occupy more space in the handheld device.The same app can be further ported to IOS for apple phones and IPads.

Dr. Shriram K Vasudevan, C, V., and S, S., “An Intelligent Boxing Application through Augmented Reality for two users – Human Computer Interaction attempt”, Indian Journal of Science and Technology, vol. 8, 2015.[Abstract]


Background/Objectives: The technological achievements seen in this modern world are very intuitive. One such intuition has resulted in this research. All of us must have seen the movie IRON MAN and the gestures the hero performs are all simply superb and it has been the motivation for us to proceed with this application that we created. Methods/Statistical analysis: Augmented Reality is a technology which enriches the real world with digital information. An Augmented Reality (AR) Interface superimposes digital objects or interactive computer graphics, on to the real world dynamically. Since its introduction, the technology has been capable of presenting possibilities that have been challenging for other technologies to offer and meet. Nevertheless, AR environments has been largely limited to simple browsing or simply viewing of virtual information registered to the real world. In a few more years, AR will definitely change the way individuals view the world. Findings: We focus at making an interactive gesture tracking system using augmented reality that duplicates the real world environment by blending virtual elements into the real world. This idea is then taken to build an application in AR, through which two users can in parallel use the Boxing application using the punch gestures. The application would let the winner announced through finding out the amount of pressure applied for knocking out the boxing bag. We have discussed in this paper the core elements required to develop an application in augmented reality, which holds good for boxing application we developed as well. The tools required are, leap motion device and unity software. A detailed form of creating an application with the output generated is given. AR is going to be the future and the software giants are all investing dollars into it. So this innovation is a step ahead in AR research which can be further extended to many other applications.

Background/Objectives: To ensure pedestrian safety in highways predominantly at night. Application: By introducing piezoelectric sensors embedded on highways, which automates the notification lamps that help both pedestrian and drivers to know each other’s presence. Methods/Statistical Analysis: The basic method we implement is getting the feed of digital HIGH and digital LOW from the piezoelectric crystals. The state of the pedestrian cross decides the output signal of the notification lamp. This helps the fast drivers on the highway to adjust their acceleration with prior alert of movement on the road. The prototype result with few minutes delay of glowing, the notification lamp can be set in real time with little more depending on the length of the cross. Findings: The night time travelers on the highway have the difficulty of vision due to optical problems of the front vehicle glass. The irritation due to high beam of the opposite vehicles distract the proper vision of the road. The pedestrians from local area are becoming a casualty of this situation. And the speed at which the drivers come is not possible to reduce in small period of time. Prior alert is required for this. More »»

Sudden, unprecedented electric blackouts and outages come as a dampener for a system that thrives on electrical energy. Reliability and efficiency are essential features for any power grid system. The conventional power grid systems are incapable of making use of real-time information from consumer side as well as the supply end for a more efficient transmission. Smart grid system, in which tremendous research has been done and which has been improvised manifold over the past decade, helps in meeting the incessant fluctuations in power demand from a huge consumer population. Smart grid brings about automation in managing the energy requirements using a two way interactive system, i.e. its ability to fetch information from the user and supply ends and utilize it to improve the overall reliability and efficiency of the transmission lines. Incorporating smart energy meters along with smart grid could come a long way in conserving electricity apart from removing manual energy meter reading from the scene. Smart meters supply the required data for the smart grid which helps the grid in providing an automated response. The paper elucidates how smart meters help in digitally tackling the issue of energy conservation in the consumer end and the utility end. More »»

People use the technology to its fullest, but they are not aware of most of the technologies that are available to them and are still in search of those advancements that have already been made available to them. This study helps to understand the number of such availabilities and for what it can be used. Action speaks louder than words. Similarly an image speaks a thousand words than a thousand worded articles. With the rather fast moving world, we don’t find time to read an article, we would prefer to look at its diagrammatic representation and understand what is inside the article rather than reading it. To find any particular information about an author or creator or any document, we type in the keywords in the search bar and look for the required information. But what if you do not know any details about the author and all you do have is just an image. How will you figure out who is the person, what are his works, who has that particular picture of his and all others details you wish to know. This is where the Content Based Image Retrieval (CBIR) comes into picture. The availability of image search engines makes your work become much simpler. It's not just for an image of humans, but those of animals, birds and dresses could also be crossed referenced using one among the several CBIR engines. With the development of technology people expect the results to be more accurate and approximate. Mere similarity between colours and texture of the material does not satisfy the user. The images that are compared and given as results seem to be the comparison of colour and category and the material, but not the actual comparison to that image. A proposed plan have been put forward which could bring about a change in the working of CBIR, giving more exact results. The plan states how to exactly compare the image rather than just the colour or texture. More »»

Augmented reality is a new technology which is capable of presenting possibilities that are difficult for other technologies to offer and meet. AR will really alter the way individuals view the world. Augmented reality X-Ray Vision is an emerging concept. While AR deals with virtual and real objects coexisting in the same space, AR X-Ray Vision is a subdivision of the broad spectrum of AR, which provides a "see through" vision among real world objects. In this paper, we have thoroughly analysed the existing methodologies dealing with AR X-Ray Vision and we have come up with a convenient method that enables easy implementation. This paper deals with creating a methodology to provide an X-Ray vision using the anaglyph technique and finally integrating it with the Leap Motion Controller to enable gesture interaction to move the window around through which the point of interest can be viewed. The limitations of the suggested methodology have also been discussed. This system enables the user to perceive depth between two regions with the help of just anaglyph glasses without the use of any head mounted display devices. Can be extended to that of medical field, where X-Ray vision is of increasing importance to view the layers of skin and bones of a patient giving the doctors and surgeons an approximate depth perception.

The following study brings to the fore a technology exclusively engineered to eradicate the snags and inadequacies persisting in the existing system of traffic control and thus aims to provide a sophisticated operation and uninterrupted course for the emergency vehicles. The traffic in Indian roads has shown a tremendous rise over the years and the conventional pre-timed traffic signals and frequent traffic congestions, delaying the road commuters, have led to outrage and chaos on several occasions. This traffic management system has proved a nuisance for the effective operation of emergency vehicles, with the public adding to the woes, as each driver races along with the signal, unmindful of the emergency vehicles. A life threatening scenario ensues when emergency vehicles get blocked by the traffic, due to inefficient traffic management system and subsequently these emergency vehicles get delayed. The existing system requires manual interruption to guide other vehicles when an emergency vehicle passes through traffic junctions. It is therefore essential to implement a self-regulating and automated system in the traffic signals to facilitate smooth movement of emergency vehicles without posing a danger to other vehicles. The innovative traffic control system devised by us provides a truly dependable alternative to monitoring traffic flow when emergency vehicles pass by.

This study is mainly inclined towards understanding why there is a necessity for Airbags and ABS in vehicles and to analyse its pros and cons. A survey is been presented in this study on whether the use of airbags and ABS is beneficial to help curb road accidents. Accidents are prevailing world-wide due to the increased number of vehicles. These unexpected happenings lead to terrific consequences like causing damage to the vehicle and the people travelling in it. Damage to the vehicle can be passed over but if a human is being killed because of an accident, then it is pathetic. Hence AIRBAGS and ABS can be implemented, so that even if a massive accident happens, the victim is left with considerable injuries rather than having his life at stake. We mainly forward through this paper, an analysis of how a human life a can be saved by implementing these technologies. The working of airbags and ABS; also how they can be more efficient is also projected in this study. More »»

Video surveillance is an important aspect in today's world, where a particular scene of area requires monitoring to avoid terrorist attacks and unauthorized entries. Vehicle recognition is an important area in object tracking and recognition. Objects may be of rigid or non-rigid in nature with varying velocity and have different features. Important features like shape, logo, color and texture are complex in nature. Hence there is a need of better algorithm for detecting and identifying the objects like car. A new method is proposed for recognizing the cars present in the video. At first the features like shape is extracted using moments, logo using the Scale Invariant Feature Transform (SIFT) and the RGB color values of the car body. Using these features the recognition is carried out to classify the type of car. Recognition of cars has range of application like, military surveillance, traffic management, autonomous navigation system, auto parking. © 2013 Science Publications.

This project aims to develop a smart and secured traffic regulatory system. With this implementation in place, the cities and metros can become a better comfortable place to drive and live in. The system should be intelligent enough to make perfect decisions in varying the signal timings and help the driver to proceed towards the road in which the traffic intensity is less. Regulating the traffic through a smart system should provide better traffic control but at the same time should be inexpensive, so here the proposed system will provide a smart and inexpensive way to regulate traffic. In the recent years, due to the enormous growth of automobile industry, vehicles have become plenty in every city. The traffic signals in many countries are controlled by traffic police manually. This makes delay in traffic flow since the concerned person need sufficient time to judge and in such high traffic it is very difficult to observe the presence of emergency vehicles. The proposed system will detect the density of traffic on each road and changes the signal timings as per the density. Only changing the signals may not help the driver in some emergency situations. So, here comes the smart point of the project. At every junction LED board will be displayed which shows the intensity of traffic and as per requirement the driver can decide his path of convenience. The entire system maintains free flow of traffic and thus regulate without manual operations. © 2031 Asian Network for Scientific Information.

This paper mainly aims at developing a FPGA-based speed controller for a synchronous machine with an internal current control loop based on a predictive current controller. Due to the complex computation schemes, predictive current controllers implemented in a full digital system are characterized by an inevitable delay in calculating and applying the switching states to the inverter. Consequently, their performances are affected and the achieved sampling frequency is limited. These digital control limitations are mainly due to the processing speed versus computational complexity trade-off. To cope up with this problem, specific digital hardware technology such as FPGA can be used as an alternative digital solution to ensure fast processing operation and to preserve performances of predictive current controllers in spite of their complex computation schemes. In order to illustrate this, an FPGA implementation of a synchronous machine speed controller based on a predictive current controller is presented and fully analyzed in this work More »»

Improper tire pressure is a safety issue that is often overlooked or ignored. A drop in tire pressure by just a few pounds per square inch (PSI) can result in the reduction of gas mileage, tire life, safety, and vehicle performance. To address this problem, an automated system that will alleviate the need for actively monitoring tire pressure was designed. This report documents the design process for an onboard tire pressure monitoring system (TPMS) consisting of transmitter in each tire and a central receiver. The Pressure data is transferred to the central receiver through wireless transmission. The system takes periodic tire pressure readings and warns the driver at abnormal pressure readings. TPMS comes with several pre-defined tire pressure settings and allows the user to enter their own pressure setting if needed. Pressure settings, current pressures and flat/leak notifications are all displayed on a liquid crystal display (LCD) located in the dash. This system will take the maintenance out of upholding tire pressure and increase tire life, fuel efficiency and vehicle safety and performance. The system development process constitutes of defining the product requirements, Transmitter sensor selection, PCB design, circuit verification, and software development, testing and integrated testing.

Software Defined Radio is an all new technology being developed in the 21st century. Over a past couple of decades many Mobile communication standards have evolved and even today researches are going to develop new standards. Different standards of Mobile communication use different type of hardware circuitry. The existing mobile communication standards are primarily regional and not global. So efforts are going on to develop systems which can support multiple mobile communication standards using same hardware but swapping the software. The main aim of this paper is to develop a model of a Software defined Radio using SIMULINK tool to implement the IEEE 802.11 standard and the Bluetooth standard. The main aim of this paper is to build various protocols for WLAN and the Bluetooth standards and to demonstrate their functionality. This includes implementation of IEEE 802.11a standard for the WLAN and basic core protocols for the Bluetooth. According to the IEEE 802.11a standard out of the various transmission modes the basic transmission mode (BPSK with 6Mbps transmission speed) was implemented. For forward error correction half convolution codes are used. The communication channel is assumed to be flat fading channel where the transmitted sub carrier undergoes flat fading. The ideal channel model for this type of channel is chosen as Nakagami channel. Regarding the Bluetooth technology all the core protocols of Bluetooth are implemented and the type of modulation is Gaussian phase shift keying and frequency hopping spread spectrum.

In Wireless Sensor Network, Device placement is a key factor for determining the coverage, connectivity, and cost along with lifetime. Managing the sensor nodes is not much easier while comparing mobile Ad ¬ Hoc Networks. But the same approach can be implemented to manage the WSN. Addressing the management of the whole network is omitted and a probabilistic scheme where only a subset of nodes is managed is provided for light ¬ weight and efficient management. Relay node placement in heterogeneous WSN are formulated using a generalized node placement optimization problem to minimize the network cost with lifetime constraint, and connectivity. Based on the constraints two scenarios are used. In the first scenario relay nodes are not energy constrained, and in the second scenario all nodes are energy limited. As an optimal solution a two-phase approach is proposed. The placement of the first phase relay nodes (FPRN), which are directly connected to Sensor Nodes (SN), is modeled as a minimum set covering problem. To ensure the relaying of the traffic from the FPRN to the base station, three heuristic schemes are proposed to place the second phase relay nodes (SPRN). Some of the heuristic approaches available are Nearest¬ to ¬ BS¬ First algorithm (NTBF), Max¬ Residual¬ Capacity¬ First algorithm (MRCF) and Best¬ Effort¬ Relaying algorithm (BER). Our contribution is centered on a distributed self organizing management algorithm at the application layer by organizing the management plane by extracting spatiotemporal components and by selecting manager nodes with several election mechanisms applied to wireless sensor nodes. Furthermore, a lower bound on the minimum number of SPRN required for connectivity is provided. More »»

The aim of the paper is to build a software based radio capable of demodulating Frequency Modulated signals with the ability to receive upto four stations simultaneously. In addition convolution encoding along with Viterbi decoding is also implemented to aid in error correction capability of digital transmission systems. The initial phase is aimed at software based demodulation of multiple channels of Frequency Modulated signals. The second phase is directed towards the Error correction using convolution encoding with Viterbi decoding for streaming data encountered in digital broadcast systems. Software Radio is a way of designing software very close to the antenna. The basic feature of software radio is that software will define the transmitted waveforms, and software will demodulate the received waveforms. This paper is developed with the help of free software based radio toolkit given by a community named GNU radio. Channel coding schemes need to be used extensively in the case of transmission of digital data over the air or through any other medium. These coding schemes also called FEC (Forward Error Correction) are used in cases where the re-transmission of the data is not feasible or possible. The channel coding schemes comes to the rescue in such cases where redundant data are sent over the transmission medium along with the message. In the receiver side, this channel coded signal is decoded to get back the original data even if the channel coded signal undergoes some interference from the noise in the transmission medium. Though the channel coding has a downside of requirement to transmit additional data over the transmission medium, the advantages offered by error detection and correction mechanisms to the receiver outweighs the disadvantage of additional data transfer rate and bandwidth requirements.

This paper discuss about the new approach of monitoring the electrical parameters for drives through power line carrier communication. Using this technique parameters like speed, voltage, current and power factors are monitored by using exceed power leads as a communication media. The communication media are located in two different places for sending and receiving the data’s which require existing 50 hertz power line. This circuit uses an asynchronous serial communication protocol and frequency shift keying modulation for realizing frequency multiplexing in the power line. These monitoring systems used for an inverter-fed induction machine are constructed using this power line communication link. A prototype model was demonstrated within the limited distance. More »»

A search engine is expected to extract results with the high end accuracy.The basic motto behind the image search engines are no different. It should retrieve the best possible match from the database for the query made. But, the accessible search engines are based on the keywords only. In order to overcome the inefficiencies in this approach, we are proposing a search based on CBIR (content based image retrieval). This paper discusses, in depth, about the methodologies to construct an efficient CBIR and also presents a novel approach which performs with increased efficiency in many aspects. We have used OpenCV, an image processing toolbox for implementing and testing our concepts. © 2013 IEEE.

In order to support a more self-motivated and stretchy communication between the learner and the system or and the tutor, two category of agents are integrated. In this paper, two types of physically challenged learner have taken for consideration, the first learner is a hearing-impaired learner and the second type is a sightless learner. Since emotions play an important role in cognitive processes and specially in learning tasks adaptive agent is integrated with emotional framework for deaf learner. For the second type of learner screen reader software like JAWS is more helpful to convert text to sound, but there is no such useful software to convert picture to sound. In this situation, sound agent will be more useful to convert picture to sound. Emotional agent can recognizes six basic emotions (happiness, sadness, surprise, fear, anger and disgust) of a tutor. Sound agent shall help to convert the basic shapes, which are used to draw any diagram or write any text (straight line, sleeping line, slanting line or curve). Tutor can also identify the mood of the student by calculating the response speed. More »»

The book " Digital Electronics" is a collection of all topics which begins from the basic electronics consisting of Boolean Algebra, converting a real time circuit into its corresponding digital form (Boolean expression) by using Karnaugh maps to ladders, shift registers, multi vibrators, ADC, DAC, digital communication. The objective of writing this book is to provide the readers all the topics which could come under digital electronics in a nut shell, thus making the book user-friendly for the readers who are not even aware of what digital electronics is all about. Also, the other distinct features of this book are the readers are provided with examples covering all possibilities to make them cognizant of the wide range of digital electronics. Henceforth, the readers will get an idea of how to think laterally a concept. Also, sufficient review questions and exercise questions with their answer are given to provoke the thinking process of the readers. Ample amount of key points to remember are given for the readers to quickly list out the points read in a chapter. There is a very idiosyncratic feature of this book which is, some concepts are dealt using pictures, figures and tabulation with an intent that basically for human beings, pictorial representation stands for a long time in memory than those explained with words. This will make the reader feel like entering into a comic world full of technical jargons, realising, understanding and enjoying each technical concept in a different way. More »»

Manuel Cor Rodriguez, Mitra, S., Thampi, S. M., and El-Alfy, E. - S. Cham: Springer International Publishing, 2016, pp. 433–447.[Abstract]


Everyone would have noticed several inconsistencies in TV ratings, with many popular programmes going off the air due to lack of sponsors, or certain shows getting undue patronage. Due to the absence of a uniform and transparent TV ratings system, several flaws exist in current rating systems, and they are open to manipulation. The purpose of our innovative invention is to mainly relay data to TV stations of what shows, programmes are watched by whom precisely without any chance for manipulation (with a responsibility of safeguarding one’s private information and biometric data). Details of name or location are not asked, for sake of user’s anonymity (a security perspective). The proposed system is aimed at eliminating shortcomings of currently used ratings systems in the world that are bogged down by issues of transparency, insufficient data, and statistical approximation. Data pertaining to user (age and gender alone) and viewed statistics (shows, time viewed) is transmitted to the cable station, for purposes of ‘feedback’ i.e., showing vital statistics of the individual and the programme watched. This system will undoubtedly be one of the most reliable sources of feedback, compared to the existing systems. More »»

Manuel Cor Rodriguez, Mitra, S., Thampi, S. M., and El-Alfy, E. - S. Cham: Springer International Publishing, 2016, pp. 879–890.[Abstract]


All the countries in the globe eventually happen to spend a lot of money towards strengthening their respective Air Force every year by spending a lot of money. Based on the observation made on the budgets framed, it will be clearly visible for anyone to understand that about 60 to 70 percentage of total money is spent towards technology up- grade and maintenance. Coming to the civilian aircraft maintenance and upgrade, the cost and budget is no inferior to the former class of military aviation budgets. We have taken this as challenge and we have come up with a solution for enhancing TTL (Total Technical Life) and reduced maintenance cost. We have built an embedded system based portable solution for measuring the usage of the aircraft and based on the usage and utilization, the maintenance can be made and this will greatly reduce the cost. The stress and strain measurements has lead us to calculate the cyclic stress that the aircraft undergoes and based on which the maintenance can be carried out. The complete implementation has been done and results are analyzed along with challenges which were resolved later. More »»

In recent days, most of the cloud users request data center in the cloud environment by applying an exhaustive data-centric workflows which leads to the major energy consumption. The major energy breaks out from the data center and makes way to CO2 emission which impacts the global warming. In this paper, we introduce optimized energy utilization in deployment and forecast (OEUDF) for data-intensive workflows in virtualized cloud systems which help to reduce the energy in the cloud workflow environment. In this approach, initially, we compute the optimal data-accessing energy path (ODEP) which helps us to deploy and configure the virtual machines; secondly, it computes the rank, according to that it will schedule the workflow activities in the cloud environment. If any unscheduled activities are in the submission pool, then OEUDF finds the suitable virtual machine and reconfigures the data center by minimizing the energy utilization. The experiment result indicates that the proposed algorithm gradually reduces the energy consumption.

Springer Berlin Heidelberg, Berlin, Heidelberg, pp. 83–89, 2014.[Abstract]


In cloud computing setup of computers power consumption among the distributed computers needs to be minimal with every server running increases the power cost by an average of 50w-100w. A real time implementation of an algorithm to minimize the power consumed in a setup of a parent computer a PIC microprocessor and connected servers is needed to manage the unwanted waste in energy. The usual traditional scheduler doesn’t meet the requirements. We program the Microcontroller to implement our algorithm which ensured that minimum number of servers run for a given numbers of virtual machines. The Distributive Power Migration & Management Algorithm for Cloud Environment that uses the resources in an effective and efficient manner ensuring minimal use of power. The proposed algorithm performs computation more efficiently in a scalable cloud computing environment. The results indicate that the algorithm reduces up to 28% of the power consumption to execute services.
