Microgripper Force Feedback Integration Using Piezoresistive Cantilever Structure, Todd R. Simon

Theses

Force feedback is an important feature in most microgripper applications, but it is commonly overlooked. To successfully implement this feature, a cantilever structure has been designed and fabricated to integrate force feedback into a microhand gripper. The piezoresistive properties of doped polysilicon are used to transduce the mechanical stress of an object pressing against the cantilever sensor, resulting in a change in resistance or voltage capable of being monitored with external hardware. The force sensing structure was designed to have a fabrication process compatible with that of the microhand, allowing for their eventual integration. This fabrication process uses both bulk …

Multi-Object Decision Making For Supplier Selection In Outsourcing, Pushpen K. Mohile

Theses

A supply chain is the system of organizations, people, technology, activities, information, and resources involved in moving a product or service from supplier to customer. The main and basic challenges in the supply chain are to plan a strategy to manage the resources and meet the demands, to select the suppliers that will deliver the goods and services that are required to build the product, to manufacture the product, to deliver the product to the customers and to make an arrangement for return of the products through customers if there is any fault in the product for servicing. This thesis …

The Botanical Thread, Kaitlin Wilson-Bryant

Theses

My thesis is an exploration of my dual desires of creation/destruction and manipulation/transformation as realized through the remediation of botanical specimens gathered from my domestic environment and transformed into works of art. Each image questions and presents an understanding of the history of botanical representation, within Western art history, as symbols of nature and femininity and the domestic skill of needlework, a traditional skill learned by women as part of the feminine. I created a conceptual dialogue with those who preceded me, intrinsically linking the acts of sewing and botany as re-interpreted feminist acts. In this work, I attempt to …

Memoir Of A Marionette, Rui Jin

Theses

My film intends to draw public awareness to the quick disappearing of traditional performing arts due to the gap caused by fast advancement of technology. Film, TV, Internet and video games have diverted public interests from old performing arts. It discusses modernity vs. antiquity. How can we progress without sacrificing all we have inherited from our ancestors. In the film, this idea is demonstrated by two trembling hands trying to reach each other – one from the marionette and the other from the old performer. They all have the same dream: laughter and cheers from children. But before the hands …

Estimating Evolutionary Dynamics Of Cleavage Site Peptides Among H5ha Avian Influenza Employing Mathematical Information Theory Approaches, Sherry Dadgar

Theses

Estimating evolutionary conservation of cleavage site peptides among HA protein of all strains facilitates vaccine development against pandemic influenza. Conserved epitopes may be useful for diagnosis of animals infected with the influenza virus, and preventing their spread in other regions [ 1]. In the preliminary stage of this study, in silico analysis of hemagglutinin was applied to predict potential cleavage sites of each strain employing

SigCleave [2] and SignalP 3.0 server [3]. The second stage of the study focused on analyzing the structure of connecting peptides of hemagglutinin cleavage sites based on the availability of the existing experimental data. Our …

Breast Reconstruction In Conserving Breast Cancer Surgery, Jamal K. Almasad

Saudi Medical Journal

Breast conserving treatment (BCT) combined with radiotherapy have proved the test of time as a sound oncological operation regarding survival and local recurrence. Successful BCT is a balance between adequate surgery and maintaining the breast9s appearance. Unsatisfactory outcome reaches 20-30% in standard techniques of BCT. Concepts described to widen the spectrum of BCT, have made an improvement of cosmetic outcome, and facilitated a liberal safety margin. Volume displacement techniques, such as glandular flap, mammoplasty, donut mastopexy, and batwing mastopexy proved useful in large breasts and volume replacement, such as latissimus dorsi flap and local flaps are of great advantage to …
