The inability to read is a great setback faced by blind community next to basic self support and navigation.
This paper describes the development of an affordable and user friendly product which will enable the blind or visually impaired to read a standard sized novel or book. Our project consists of two components – software and hardware. Software part consists of an Android based application that converts images of printed text into audio output. For text recognition and extraction from image, we have used Android API from Tesseract
toolkit which provides the OCR and Leptonica image processing libraries. For converting this textual output of OCR to audio we have used the inbuilt Android Text to speech engine. The user interface is specifically designed for visually impaired people and contains voice instructions at every step. The hardware component comprises of a book stand that provides a setup for holding camera and book to be read. Their positions are fixed so as to obtain optimum output with the least amount of effort by the user. The stand is not only strong and sturdy, but also portable.

The technologies currently used for navigation are GPS and GIS, but they dont provide reliable results in an indoor environment and are not so user friendly for a visually impaired person.We would like to propose a system that would acoustically guide the visually impaired person to his desired destination in an indoor environment. The system proposed is to have a network of ceiling mounted IR transmitting nodes that mark different location of the building and a headphone mounted receiver device which receives the IR data and guides the person wearing the headphone accordingly. The system is not only easy to use but also low cost. We have tested the system in CEP building and have found out the limitations of our system and how it can be improved.

Serious games and especially their use in healthcare applications are a rapidly growing area of research. KinectoTherapy incorporates serious games that process 3D input using the Microsoft Kinect motion sensor to build an effective rehabilitation system. Through discussion with a number of physiotherapists and occupational therapists, it was determined that the physically handicapped typically lack enthusiasm for rehabilitation and this hinders their recovery and ability to care for themselves. Using research and recommendations from therapists, this project involves implementation of exercise routines that target different parts of the body and aid people with motor disabilities stemming from cerebral palsy, spinal cord injury, post stroke and hereditary muscle ailments amongst others.

III-nitrides semiconductor devices are being widely used as a good technology vehicle for high-frequency and high-power applications. In particular, AlGaN/GaN High Electron Mobility Transistors (HEMT) are currently the most promising devices for microwave power amplification. These devices can work efficiently under wider bias ranges without breakdown due to better material properties responsible for high power/high frequency, i.e., large band gap, high electron drift velocity and high breakdown electric field. Since these devices operate at high voltage levels which may result in large currents and can lead to considerable heat generation causing significant increase in the channel temperature and thermal resistance that adversely affects the electron transport properties. The reliability and power performance of AlGaN/GaN HEMT power devices depend critically on thermal resistance and operating channel temperature. Therefore, an accurate estimation of thermal resistance and channel temperature is highly desirable. In this study, reported closed form expressions are used for estimating the thermal resistance of 0.25 micron gate AlGaN/GaN HEMTs through simulation and its variation with geometrical parameters for different substrates, e.g., SiC, Sapphire, Si, GaN and Diamond. In this project, simulation is carried out in MATLAB R2008b to predict the thermal behavior of AlGaN/GaN HEMTs with industry standard geometrical parameters.

Manipulation in image has been in practice since centuries. These manipulated images are intended to alter facts – facts of ethics, morality, politics, sex, celebrity or chaos. Image Forensic Science (Image Forensics) can be used to detect manipulation(s) in a digital image. There are many standard way to analyze an image for manipulation. We propose a new method that is based on light and its shade. It measures the direction of light source and uses the light based technique for identification of any intentional manipulation in the said digital image.

Double clad fibers are a way employed to power scale the rare earth doped fiber lasers that find application in many practical fields namely optical measuring, telecommunications, spectroscopy, sensors and medicines. The shape and positioning of the core and inner clad are extremely important as the absorption characteristics of the fiber is dependent on them. Also the pumping technique employed governs the coupling efficiency. Here we have proved that triangular shape in the inner cladding is optimal and the IVGT (Imbedded V Groove Technique) for pumping can be used to circumvent the typical deficiencies of end pumping techniques. As we move to higher power scale, the nonlinear effects that were negligible earlier become prominent. Photonic crystals can be employed in the inner and outer clad to reduce the nonlinear effect. The nonlinear effects can be classified into two categories namely the material dispersion and the waveguide dispersion. Also we know that the material dispersion characteristic of air is lower than any other material, thus the use of air holes (photonic crystals) may reduce the nonlinear effects.

So in the due course of the project we have proved that the triangular clad is optimal using geometric optics. We have also calculated the numerical apertures, the angle of incidence and the hole density in the inner and the outer clad thereby integrating the photonic crystals with double clad fibers.

All-Optical Networks employing Dense Wavelength Division Multiplexing (DWDM) are believed to be the next generation networks that can meet the ever-increasing demand for bandwidth of the end users. The problem of Routing and Wavelength Assignment (RWA) has been receiving a lot of attention recently due to its application to optical networks. Optimal Routing and Wavelength Assignment can significantly increase the efficiency of wavelength-routed all-optical networks. This thesis presents some new heuristics for wavelength assignment and converter placement in mesh topologies. Our heuristics try to assign the wavelengths in an efficient manner that results in very low blocking probability. We propose novel static and dynamic assignment schemes that outperform the assignments reported in the literature even when converters are used. The proposed on-line scheme called Round-Robin assignment outperforms previously proposed strategies such as first-fit and random assignment schemes. The performance improvement obtained with the proposed static assignments is very significant when compared with the dynamic schemes. We designed and developed a simulator in Matlab6.5 that supports the 2D mesh topology with DWDM as well as random topology generation. We ran extensive simulations and compared our heuristics with those reported in the literature. We have examined converter placement in mesh topologies and proposed that placing converters at the center yields better results than uniform placement when dimension order routing is employed. We introduced a new concept called wavelength assignment with second trial that results in extremely low blocking probabilities when compared to schemes based on a single trial. Our proposed schemes are simple to implement and do not add to the cost. Thus we conclude that wavelength assignment plays more significant role in affecting the blocking probability than wavelength converters. The algorithm yields significant improvements in terms of the request blocking probability over traditional techniques. Also we have observed from simulated results that by using even limited conversion of degree two is sufficient to achieve performance of full conversion. We have achieved this performance by using our better heuristic technique of establishing lightpaths.

Designing an Optoelectronic Integrated Circuit (OEIC) is an attractive field of research as it bridges the interface between electrical and optical components. The design of laser driver in optical transmitter is very ciritical because it requires large output current and high speed. To date, majority of laser drivers have been designed using Bipolar Junction Transistor (BJT) due to wider bandwidth and good quality of passive components. However, the standard digital Complementary Metal Oxide Semiconductor (CMOS) technology provides advantages, such as, low power, low cost of fabrication due to high production yield, and a higher degree of integration. Thus, the silicon CMOS technology, which is well known for low cost and high density, is preferred to design an Optoelectronic circuitry.

Under this thesis, the work undertaken pertains to devising cascode-based laser driver circuit operating at 2.5 Gbps, using Hewlett Packard CMOS26G 0.8 micron CMOS process. The devised circuit integrates well with the 1550nm rate equation based equivalent circuit model generated from R-soft design tool kit OptSim 3.6. This is definitely a step forward on the existing topologies, which have worked on 850nm VCSEL. The thesis projects reduction in number of transistors and, consequently, the chip area occupied by the driver. In nutshell, what has been done on this score and what remains to be done has been explained in detail in chapter-4 of the thesis under the title “conclusion & future scope”.
