MEMS based Antenna array

Evolution of communication technology is pushing the limits beyond those of conventional radio frequency and millimeter-wave devices. A key trend in this evolution is miniaturization and ultrahigh density integration of radio/microwave frequency devices. Micro-electromechanical systems (MEMS) technology provides the opportunity to develop micro-scale RF devices and satisfy the market demand.

Comparative Study of Fixed-Rate Coded and Rateless Coded Cooperative Wireless Networks

Fixed-rate coding for cooperative wireless networks with decode-and-forward (DF) relay processing has received much attention. Yet, only a fairly narrow body of research exists on rateless coded DF relaying networks. Little is known about how the performances and complexity implications of fixed-rate and rateless coded systems compare. Meanwhile, such comparisons play a vital role in the system design for cooperative networks.

Robust detector design based on Stochastic Resonance

The stochastic resonance (SR) is a phenomenon discovered recently in some nonlinear systems where addition of a certain amount of noise can, somewhat paradoxically, enhance its performance. It has found applications in biological sensory systems [1] such as visual, auditory systems, and tactile system as well as engineering applications such as ac-driven Schmitt triggers, and bistable ring lasers. The bistable systems (BS) are nonlinear systems [4] that are widely used as SR systems.

Resilient software update

In a typical scenario, a large heterogeneous software system, installed on many different sites and composed of several interacting components, exchanging data with several different protocols, must be updated to correct some defects, add new functionalities, or replace some obsolete components without breaking the system and while keeping its dependability.

A Self-Balancing Omni-Delta Robot

In this project, a modified Delta parallel robot is designed in which the number of passive joints is reduced, and an active joint is added to the hardware. To the best of our knowledge, this configuration seems to be the first of its kind.

In this project, kinematic and dynamic analyses will be performed. Active compliance control and collision anticipation algorithms will also be developed for this new design. This configuration will be used as the “waist” of an omni-directional, self-balancing service robot. Methodology and novelty of approach and/or application

Development and Implementation of Technology for Haptics-Enabled Image-Guided Operation of the Amadeus® Robotic Surgical System

Robot-assisted minimally invasive surgery is an emerging field in research and industry. A major challenge with the existing medical robotic systems (including the da Vinci® from Intuitive Surgical) is the lack of haptic feedback (sense of touch). On the other hand, medical imaging is only used for direct visualization in the existing systems. Certain surgical sub-tasks (such as simple cuts, cleaning and suction, etc.) can be automated using imaging feedback and visual serving to assist surgeons during the operation.

Design of co-channel interference mitigation techniques through a novel radio over cable (RoC) architecture proposed for enhanced indoor performance of femtocell networks

Wireless communication devices have become an essential part of our lives and new ubiquitous applications are evolving rapidly. The spectrum of wireless links is limited and its efficient utilization via smart technology is very crucial to fulfill the ever increasing demand. Femtocell using a low-power home base station is a promising technique for serving indoor quasi-immobile users. It has the potential to provide better coverage and increased data rate to indoor users and to support more users/services by offloading the major traffic from the macrocell to the underlay femtocells.
