- Description:
- Design and validation of NTRU public-key cryptosystem is a relatively new Public Key Cryptosystem. Public Key Cryptography or Asymmetric Cryptography is used in areas of digital signatures and key exchange. RSA is an acclaimed Public Key cryptosystem that is in use since 1977. However, it is very slow in comparison with Symmetric Cryptography systems in processing bulk data encryption and decryption. In contrast, NTRU runs much faster on large data systems than RSA and has become a very popular algorithm today in terms of data encryption and decryption. The key generation process in NTRU is much faster than that in RSA, and this process is one of the most important processes in Public Key Cryptography. FPGAs are one of best hardware used for implementing reconfigurable computing. Reconfigurable computing is very popular because it is capable of computing many different applications with a great speed. An important feature of reconfigurable computing is that computations are performed in hardware, but the flexibility of a solution in software is maintained at the same time. The purpose of this project is to initially explain the NTRU algorithm which is a proprietary algorithm patented by NTRU Cryptosystems. NTRU Crptosystems has recently become a part of Security Innovations, a leading provider of security solutions. This project advocates a hardware implementation of the NTRU public-key cryptosystem which is made of three important phases- Key Creation, Encryption and Decryption. The system has been implemented in Verilog HDL, simulated using Synopsys from VCS and synthesized using Xilinx ISE Design Suite.

- Description:
- This report details the different stages of the recently initiated Phase I clinical trial of a new modality of cancer treatment in India. The clinical trial involves the addition of hyperthermia or heat treatment to existing treatment techniques such as radiation or chemotherapy, with the aim to improving patient response. Earlier studies have showed that the combined protocols can double the patient response. The current trial involved 14 patients in a palliative mode of treatment, and the report covers the planning, organization, and carrying out of the clinical trials. Currently, the trial has been initiated at one cancer center in India, but will be extended to another center shortly. This report can be used as a base on how the hyperthermia treatment is conducted practically and also includes details about the procedure and protocol followed for hyperthermia treatment together with radiation and chemotherapy treatment. In this collaborative project, Krishna Ramya Cherukuri and Vijaya Chandra Yadav, individually contributed to the background research on hyperthermia treatment and its practical application in the clinical trial. Krishna Ramya Cherukuri did background research on hyperthermia treatment and its usage and in the selection of different kinds of equipment used in the treatment. Vijaya Chandra Yadav did research on practical clinical trials involving combined hyperthermia and radiation or chemotherapy protocols and developed recommendations regarding how the hyperthermia treatment should be implemented in India, taking into account the demographics and cancer spread in that country.

- Description:
- The main objective of this project is to analyze nonlinear effects in optical fiber and to discuss how these effects cause dispersion in input signals. This project also discusses the pros and cons of nonlinear dispersion. Nonlinear dispersion may be advantageous in improving the performance of an input signal at the receiver side but may be disadvantageous in restricting the transmission rate through an optical system. The nonlinear effects were simulated with the OPTSIM tool and analyzed using the eye pattern method with respect to bit error rate and Q factor. Simulation results of the OPTSIM tool were also compared with the numerical analysis of nonlinear effects using non-linear Schrödinger equation, which is coded and simulated in MATLAB

- Description:
- The purpose of this project is to gather and document the existing criteria, rules, and practices used by the Investor Owned Utilities (IOUs) in California for physical interconnection of Distributed Generation (DG) and to identify existing technical issues and concerns associated with interconnections under the current rules. The criteria set by the National Standard IEEE 1547, California Public Utilities Commission (CPUC) Rule 21, and the standard practices used by a sample major IOU will be presented and compared. Implementation problems and issues associated with the presently used rules and criteria are documented and discussed. The project also intends to verify and further investigate any system protection related concerns using system modeling and simulations. Known protection related impacts due to relay desensitization and overstressed equipment will be simulated using industry level software, and the results from the analyses will be presented. Suggestions and recommendations will be provided for future research and studies in the interest of developing future criteria and recommended practices for DG interconnections. The project summarizes problems and issues with the interconnection of increasing levels of DG, which is one of the topics of major focus in electrical power systems.

- Description:
- The object of the project is to design, simulate and fabricate a broadband microstrip balun operating at a center frequency of 5 GHz and wide bandwidth of 3.5 GHz. In this project report, I present one design with the capacitor in the middle of coupled lines and the resistor at the input port. This balun design will find various applications in the wireless industry such as push-pull configuration and mixers. The Advanced Design System (ADS) software was used to design and simulate the model. This design is aimed to provide a coupling of –17 dB at both output ports and a phase difference of 180 degrees between the two output ports over the specified frequency range, and give low voltage standing wave ratio (VSWR) while maintaining good amplitude balance. The emphasis is to obtain a high degree of amplitude balance, phase balance and low VSWR, and keep in tune with high performance demanded by wireless systems.

- Description:
- This project focuses on a physiotherapy technique in which a therapist uses the thumbs to apply force to the spinal column of a patient. A therapy session consists of a series of bouts. Because the thumbs tire quickly, the bouts usually are short, about 30 s in duration. A hand-held device is proposed for the therapist to use in place of the thumbs, which consists of a mechanical apparatus with a force to voltage transducer and an electronic interface. This project deals with the development of the electronic interface between the mechanical apparatus and the therapist. A microcontroller with a liquid crystal display and a joystick is used. For debugging purposes, an external potentiometer circuit is used to simulate the output from the force sensor. The controller interface is coded to follow a bout structure and to allow the therapist to initialize the bout time, monitor the performance of the therapy, and view a summary. The therapist navigates through this interface structure via the onboard joystick. Once a bout session has ended and the therapist views a summary of collected force measurements, the next bout may begin. While the interface developed provides much feedback to the therapist using the device, there are still some areas of development that require attention. These areas, which are left to future developers of this project, include exporting data from the microcontroller and providing data viewing with analysis tools.

- Description:
- The increased use of nonlinear electronic equipment has become a concern in most utility power systems. Nonlinear loads draw current discontinuously during the cycle of the input voltage waveform and produce low power factors when harmonics are taken into account. This increases line current and can limit the available capacity of branch circuits. In addition, harmonic currents can cause heating in utility and facility transformers. Modern personal computers and other information technology equipments utilize “switching regulators” or switch mode power supplies, to convert utility AC power to regulated DC power. These switching regulators and switch mode power supplies generate high third and fifth harmonic current. If the equipments are not properly designed or rated, equipment will often malfunction when harmonics are present in an electrical system and that equipment can be personal computer in business environment or an ultrasonic imaging machine in a hospital. To eliminate this harmful effect, in depth study of power system analysis is required. In this project, study of power quality and detailed analysis of harmonics is performed. This project will look at causes and effects of harmonics in power systems. In depth analysis is performed and mathematical model and software simulation for passive harmonic filter is developed to design inexpensive solution for the utilities and power industries. And the results will be compared with the industry standards.

- Description:
- The purpose of this project was to optimize the bonding parameters to develop an adhesive wafer bonding process that produces a defect free and relatively strong bond using SU-8 as an intermediate adhesive layer at the lowest possible processing temperature. There are a variety of bonding parameters that have a significant impact on void formation at the bond interface, defect density and the bond strength. The influence of several bonding parameters on the resulting bond quality was studied to identify the Key Process Input Variables of soft bake temperature, UV exposure dose and bonding temperature. Three different values were chosen for each process variable and the bonding process was repeated in random order for all possible combinations of process variables. The quality of a wafer bond is determined by the fraction of interfacial area in intimate contact and the strength of the bond interaction. Therefore, the void area and fracture strength of each bonded sample was considered as Key Process Output Variables. Bond characterization, which involves bond interface imaging to detect defects and measure void area, and tensile load testing to calculate the fracture strength, was done on all the bonded wafer pairs. All the bonded wafers were scanned using a Sonoscan Scanning Acoustic Microscope (SAM) and C-Scan images were used to determine void area. The six inch bonded wafers were diced into 5mm X 5mm size test specimens and each was scanned using SAM to calculate the interface bond area. Tensile load testing was done on the diced test specimens of each bonded pair to calculate the fracture strength. A general linear statistical model was developed to perform analysis of variance to determine the impact of the process input variables soft bake temperature, exposure dose and bonding temperature on the process output variables void area and fracture strength. The bonding parameters soft bake temperature, exposure dose and bonding temperature were successfully optimized to develop an adhesive wafer bonding process that can produce a defect free and strong bond using SU-8 as an intermediate adhesive layer at the optimum conditions of 90 oC soft bake temperature, 100 mJ/cm2 exposure doses and 115 oC bonding temperature.

- Description:
- The focus of this project is to carry out an accurate simulation study of a 3- element array of rectangle horn antennas forming a focused near field beam. This study has useful application for clinical hyperthermia which is the therapeutic treatment of tumors in the body by heating caused by focused RF or microwave radiation. This principle of treatment is proved to be very useful for cancer treatment usually in conjunction with traditional radiation or chemotherapy, and can even double the tumor response rate as compared to radiation alone.. The 3-element array set up consists of a central focusing element and two surrounding directing elements. The focusing element can be axially adjusted and surrounding elements are fixed to focus the beam of a required point, which is necessary in hyperthermia treatment. In this project the simulation results were obtained from ANSOFT HFSS simulations.
