[1] ADAPTIVE SPEED CRUISE CONTROL

PROJECT GROUP: ADITYA GANDHI, ANDESH SHINDE, SOHAN SHINDE, SAJIV SUKUMAR

GUIDE: DR. S T GANDHE

Abstract: Adaptive speed cruise control (ascc) is an automotive feature that allows a vehicle’s cruise control system to adapt the vehicle’s speed to the traffic environment. A radar system attached to the front of the vehicle is used to detect whether slower moving vehicles are in the adaptive cruise control vehicle’s path. If a slower moving vehicle is detected, the adaptive cruise control system will slow the vehicle down and control the clearance, or time gap, between the ascc vehicle and the forward vehicle. If the system detects that the forward vehicle is no longer in the ascc vehicle’s path, the ascc system will accelerate the vehicle back to its set cruise control speed. This operation allows the ascc vehicle to autonomously slow down and speed up with traffic without intervention from the driver.
This project will consist of an adaptive speed cruise control circuit models which will take simulated signals as its inputs. The circuit models will accordingly provide controlling signals to the simulated automobile servo-mechanism system.

[2] PATH FINDING ROBOT USING ROBO-VISION

PROJECT GROUP: DESAI PARTH, TAMBE VISHAL, SALAME RAVIKANT

GUIDE: PROF. S. T. GANDHE

Abstract: robots that coexist and assist human beings require automatic functions to perceive, decide and perform tasks by themselves. Vision is a process for a robot to acquire signal, information and knowledge about the external world. Thus vision enables a robot to become intelligent and autonomous in undertaking manipulation, locomotion and social interactions. Generally, robots are used where working for humans can be dangerous. Robot-vision is making its way in robotic security systems, autonomous factories and robotic health care systems. ‘Vision-bots’ respond to a visual set of instructions and act them out in the environment accordingly.
The designed project describes the development of a prototype of a path finding robot which is implemented using camera vision. The prototype is developed using a webcam. The camera is used to take images in real time and transfer to a computer. The prototype is interfaced serially with the computer where in the processing of the images taken by the camera is performed and according to the results corrective action is being taken. The prototype is designed for the task of avoiding obstacles along its path.
The designed prototype serves a transport system which will reduce manual labor drastically and also bring about greater efficiency by making the system absolutely automatic and error free. Also it harnesses manual labor by diverting it to other more important tasks than transportation of office documents, hardware etc.

PROJECT GROUP: SAURABH SHAH, CHINTAN PARAB, PREETAM RODRIGUES, URMISH SHAH

GUIDE: Dr. S. T. GANDHE

Abstract: This report investigates a promising method of control engineering which is fuzzy logic modeling. At the start of the report the ‘Inverted pendulum’ system is introduced and its controllability is studied in detail. The theoretical background to fuzzy logic is detailed further. The application of a Fuzzy Logic Controller (FLC) to the inverted pendulum problem is presented in this report. FLCs have been used to control many dynamic systems. The inverted pendulum represents a challenging control problem, which continually moves towards an unstable state. Techniques for manually tuning a complex FLC are also implemented in this project. The inverted pendulum is a classic problem in dynamics and control theory and widely used as benchmark for testing control algorithms like PID controllers, neural networks, fuzzy control, genetic algorithms, etc.

[4] PERFORMANCE EVALUATION OF EMBEDDED LINUX ON AN ARM PROCESSOR

PROJECT GROUP: AMIT KARANDE, ANKIT BANSAL, PRASHANT NAIR, SHANTANU KULKARNI

GUIDE: PROF. Y. S. RAO

Abstract: The aim of the project is to build an application to test the real time performance of the ARM processor. The inverted pendulum is chosen as the application because it is a very good benchmark for testing any control algorithm. An approximate mathematical model of the inverted pendulum is developed on Atmega8535. The controlling algorithm is run on the ARM board which controls the inverted pendulum. The project also involves simulation of uClinux OS on Skyeye. uClinux is the microcontroller version of the desktop Linux, aimed to work with MMU-less processors or with architectures that use it for memory protection only.
The report details the results observed during the running of the controlling algorithm for various load conditions. The process-load on the ARM board is increased by running a thttpd web server and varying the number of clients. The controlling algorithm is also run on desktop for performance comparison. Finally, the result analysis of the controller algorithm is carried out and the future scope of the project is discussed.

[5] ENVIRONMENTAL SOUND MANIPULATOR

PROJECT GROUP: ASHUTOSH O. SAHU, VRUSHALI GAONKAR

GUIDE: Prof. Y.S.RAO

Abstract: The health hazards of noise pollution cannot be more stressed in our day to day life. Efforts are being made to reduce the noise but loud noise cannot always be avoided. Blocking the entry path of the sound seems to be a solution but that comes with a disadvantage that in this case all the sounds will be blocked. In such a scenario a device which would allow only sounds up to a threshold level to enter unaffected into the ears and compress the sound level above the threshold level to a comfortable level will be of a great help. The proposed project aims at implementing such a device with the help of VLSI approach.

[7] LOCAL POSITIONING SYSTEM

PROJECT GROUP: TARUN CHADHA, ADITYA DAVE, ARJUN LOKUR, ARVIND BHAT

GUIDE: Prof. K. T. TALELE

Abstract: The aim of this project is to develop an efficient user friendly navigational system to aid individuals circumnavigate their way about large confined areas like malls with a minimum degree of difficulty. This idea occurred to us upon realization of the fact that with the ever increasing size of malls, it would become exceedingly difficult to find arbitrary directions around the mall. Our idea is to integrate the technological processes of image processing and a mobile phone client-server interaction to create an application platform capable of providing efficient directional assistance to any potentially lost individuals. The basic process involved is the client being able to use a Bluetooth enabled cell phone or a cell phone integrated camera to assist in determining the client’s location within the mall and also possible routes one can take to reach the desired destination.

[8] LINUX CLUSTERING USING MPI

PROJECT GROUP: ANKUSH KAUL, POOJA JHA, SNEHAL KHARACHE, SWAPNA KALE

GUIDE: PROF. M.M. PARMAR

Abstract: A computer cluster is a group of loosely coupled computers that work together closely so that in many respects it can be viewed as though it were a single computer. Clusters are commonly connected through fast local area networks and are usually deployed to improve speed and/or reliability over that provided by a single computer, while typically being much more cost-effective than single computers of comparable speed or reliability.
Clusters built from open source software, particularly based on the GNU/Linux operating system, are increasingly popular. Their success is not hard to explain because they can cheaply solve an ever-widening range of number-crunching applications. A wealth of open source or free software has emerged to make it easy to set up, administer, and program these clusters.
This work aims at an implementation of free and open source clusters for performing scientific computations at a faster pace.

[9] WIRELESS NETWORK SECURITY AND MONITORING

PROJECT GROUP: PRAJYOT BHISIKAR, CHETAN BHARAMBE, SHWETA MANDILIA, NAKUL CHOKSI

GUIDE: PROF. M. M. PARMAR

Abstract: Wireless technologies have become increasingly popular in our business and personal lives. An increasing number of government offices, military services, intelligence agencies, banks, educational institutes etc are using wireless technologies in their environments. In order to protect useful information and illegal use of network, strategies should be developed that will mitigate risks of unauthorized intrusion of wireless networks; as they integrate wireless technologies into their computing environments.
Cryptographic studies have demonstrated that an intruder who collects enough data can threaten a wireless network in three ways: by intercepting and decrypting the data that is being transmitted over the air, by altering the data that is communicated, and by deducing and forging the WEP key to gain unauthorized access to network and Internet services. This could be accomplished in a matter of hours on a busy, corporate WLAN.
Our project aims at designing a system in which WLAN can be used with an advanced security levels to prevent illegal use of networks. This project aspires to build a secure authentication infrastructure using Wi-Fi Protected Access using open source implementations of the RADIUS protocol and the Lightweight Directory Access Protocol (LDAP). LINUX will be used for configuring RADIUS server and LDAP server Thus, security and management of WLAN will be the main task of our project.

[10] HOME @ MOBILE

PROJECT GROUP: VIRAL DHABALIA, VAIBHAV MANGRULKAR, DIVYA MOHONDOSS

GUIDE: PROF. N.A. BHAGAT

Abstract: In this fast moving world, people are compelled to work the entire day giving the very little time for rest. In such cases there are two things that come into picture 1) the number of tasks that they have to perform and 2) the time taken to complete them and day by day these two factors are increasing. This day-day problem associated with millions of people for whom time becomes a major factor has provoked us to take up this project. Thus automation helps people to control the various devices at home and at office by using a mobile which sends commands to the devices.
As of now in this project we plan to on-off the devices using Bluetooth technology. This project can be extended to control the various parameters of the devices. Along with Bluetooth technology, GSM technology can also be used to increase the range of controllability. This project if implemented in large scale will create a major impact on our daily life.

[11] IMAGE COMPRESSIONUSING WAVELET TRANSFORM MODIFIED SPIHT ALGORITHM

PROJECT GROUP: NIRAV V. DOSHI, SAURABH Y. MOHILE, SHRADDHA K. MEHTA

GUIDE: PROF. N. A. BHAGAT

Abstract: The Set Partitioning In Hierarchical Tree Structure (SPIHT) is a codec which works on bitmap images. The images could be color images as well as grayscale. SPIHT works on the Discrete Wavelet Transform (DWT) of an image. In a DWT, the maximum information of the image gets concentrated in the upper left corner, while the information content goes on reducing as we move towards the bottom right corner. Thus, compression is started with the coefficients in the upper left corner and progressed towards the coefficients in the bottom right corner. As a result, pixels having maximum information content get compressed first, which leads to an accurate image reconstruction after decompression. SPIHT progressively compresses and decompresses the image, which means that compression and decompression can be done up to the desired level. Full compression would lead to a lossless compression, while partial compression would lead to a lossy compression. Thus, SPIHT allows the trade-off between size and quality.
Although SPIHT is a very well designed algorithm, some minute improvements are possible. After a detailed exploration of the minutiae of this algorithm, application of some additional mechanisms seems to enhance its outcome.

[13] BRAIN STIMULATION USING BIO-FEEDBACK

PROJECT GROUP: ALPA C. TRIVEDI, DARSHANA E. SAWANT, REEMA UPENDRA, JANHAVI D. KANVINDE

GUIDE: PROF. S.S.MANE

Abstract: In today’s competitive world, stress is a part of life that everyone deals with at one time or another. Stress can be a cause of many psychological disorders like depression, sleeping disorders, lack of concentration etc. This calls for a need of stress management. Everyone has different levels of handling stress and different coping mechanisms. The threshold level of an individual can be increased by stimulating the brain with the help of a brain entrainment tool.
Brain stimulator is one such tool which provides visual and audio stimulation to the brain. This stimulation tends to generate corresponding brainwave patterns. Brain mainly consists of Hindbrain, Midbrain and Forebrain. Forebrain is subdivided into four lobes namely, Occipital Lobe, Parietal Lobe, Temporal Lobe and Frontal Lobe. Brain Stimulator mainly concentrates on Occipital Lobe and Temporal Lobe. Occipital Lobe generates brainwaves depending upon stimulation given through eyes (visual) and Temporal Lobe generates brainwaves depending upon stimulation given through ears (audio). There are different states of brain namely; Delta (Sleep), Theta (Meditation), Alpha (Relaxation), Low Beta (Concentration), High Beta (Alert) which are related to different brainwave frequencies. To enter one of these states, external stimulation is given with help of an electronic circuitry.
By presenting the external stimulation to the brain, within a few minutes, the brain begins to mimic or follow the same frequencies as the stimuli (the beats and pulses). The Frequency Following Response that the mind experiences through light and sound stimulation provides a focus for the brain. This focus enables the user to reach more quickly and effectively to the optimum state of mind targeted for the task at hand.

[14] RAILWAY POSITIONING SYSTEM

PROJECT GROUP: M. TILAK, TOSHNIWAL RAVI, VALIA NIMISH, ZAVERI JAGRUT

GUIDE: MR. S.S. MANE

Abstract: Day by day, the population in country like ours is increasing. Railways are the most used transport system in India and especially in city like Mumbai. The huge railway network has to meets the increasing demands for travelling by trains. Millions of people travel by train’s everyday but face the problem of not being punctual. Each one of us wants to reach the desired destination on time. No one wants to miss a train at a given time for the fear of being late as there is a large time between trains in succession. As a result most of the trains are crowded and none patiently ‘waits’ for the next train. The above problem arises due the present existing system in railways consisting of pre-defined set of signals; due to which the distance between sets of signals is fixed as a result the distance between two trains travelling on the same track is more than required . This day-day problem associated with million of commuters for whom time becomes a major factor has provoked us to take up this project.
Our basic aim thus becomes to increase the frequency of trains. We plan to achieve our objective by tracking the trains by using antennas oriented in triangular fashion. Each set of antennas (3) would communicate with their respective base stations to give information regarding the tracked trains to the common control room. Depending on parameters like distance between the trains, their length, load , braking curve and most importantly the speed the of the train travelling ahead, the control room will process the above data ( based on an algorithm) and accordingly give the maximum permissible speed by which the train travelling behind can traverse keeping a minimum safe distance between them.
Thus there is a relative motion of trains as a result the distance between the trains which were more than sufficient in the existing system is reduced significantly. Therefore we can run more number of trains in a given period of time thereby increasing their frequency.
As of now, in this project we only plan to simulate our results. We are using tool like ns (network simulator) and MATLAB to achieve our motive. The practical considerations have to be taken into account while implementing it. If successful it will create a major impact on our routine travel.
