Study Of A Non-Contact Gaging System Of Inspection, Gordhanbhai Ketan Patel

Theses

The quality control function has traditionally been performed using manual inspection methods and statistical sampling procedures. Manual inspection is generally a time - consuming procedure which involves precise, yet monotonous work. It often requires that parts be removed from the vicinity of the production machines to a separate inspection area. This causes delays and often constitutes a bottleneck in the manufacturing schedule.

As a solution to the above problem a Non - Contact Gaging System developed by Optical Gaging Products, Inc., has been used here to study the feasibility of using an automated inspection system and a procedure of developing …

Contextual Trappings: A Strategy Of Contradiction, Richard Metzgar

Theses

The focus of this thesis is to examine a multiplicity of ideas in which the presence of contradiction is the unifying component. This "process" of examination has been decidedly "expansive." I am emphasizing process and expansive because these terms could best describe the underlying philosophical attitude driving this body of work; process in relation to both conceptual as well as material considerations. Conceptually, I have given myself the opportunity to examine a broad range of issues, understanding the realization that all levels of worldly stimuli become raw material for an artistic statement. Similarly, in regards to material approaches, selecting the …

Bio-Mechanics Of The Hip Joint And The Engineering Considerations In The Treatment Of Unstable Intertrochanteric Fractures, Manoj D. Nene

Theses

Numerous previous attempts have been made to determine the magnitude and the direction of forces acting on the hip joint. The mechanism of femoral neck fractures and the frequently occurring failure of its internal fixation has led engineers to analyze the forces involved. An unstable intertrochanteric fracture is one which lacks continuity of the bone cortex on the opposing surfaces of the proximal and digital fragments. A mathematical model is created in this study to examine the 135° and 150° nail plate. The results give an approximate estimation of stresses on the two plates. A 3D finite element model of …

A Biomechanical Analysis Of Three Humeral Fracture Fixation Systems, Alina Michelle Waite

Theses

Often, humeral fractures requiring internal fixation can be a challenging orthopaedic procedure. Each method of treatment possesses clinical and biomechanical advantages and disadvantages. Rigid plate fixation is highly successful in treating a large variety of long bone fractures. Nevertheless, excessive soft tissue dissection is necessary, and vascular and neural anatomy of the humerus can make plate application and removal difficult. An intramedullary nail offers a relatively simple procedure, thereby reducing these anatomical concerns. However, rotational instability at the fracture site is a common complication with a conventional intramedullary nail. Thus, a study was conducted to evaluate a new interlocking intramedullary …

Effect Of Dietary Lipids On Rat Alveolar Macrophage Function, Sangeeta R. Mehta

Theses

An in vitro assay has been developed to measure bacterial uptake by rat alveolar macrophages. The assay is used to study the effect of a diet rich in high omega-6 linoleic acid on the phagocytic response of the macrophages obtained from young and old rats. Within the range of diets studied, no significant difference (p<0.05) is observed in the phagocytic capability of macrophages from young rats. Significant difference is observed between diet groups for the old rats (p<0.05), with the group on a fat-rich diet showing suppressed phagocytic response. Significant difference is also found between age groups for the same diet (p<0.05), older animals showing suppressed response.

Implementation Of Automated Assembly, Kang H. Kong

Theses

Research has shown that about 60 - 80% wealth producing activities is related to manufacturing in major industrial countries.

Increased competition in industry has resulted in a greater emphasis on using automation to improve productivity and quality and also to reduce cost.

Most of the manufacturing works such as machining, painting, storage, retrieval, inspection and transportation have changed to automation successfully, except assembly. Manual assembly is predominant over automatic assembly techniques due to inherent assembly problem and the fact that the assembly machines lack the innate intelligence of human operator and lack sufficient flexibility to changeover when product designs and …

The Application Of Adaptive Step-Size Control In The Numerical Simulation Of Calcium Release In Vascular Smooth Muscle, Michael John Sydor

Theses

An algorithm for the adaptive control of numerical integration step-size is developed and implemented for the simulation of a three compartment model for Vascular Smooth Muscle. The three compartment model accounts for the simultaneous diffusion of Ca, ⁴⁵Ca, EGTA, Ca-EGTA, and ⁴⁵Ca-EGTA, and is an extension of a two compartment model by Diecke for the simultaneous diffusion of Ca, EGTA, and Ca-EGTA. The addition of the third compartment is to account for the presence of the Sarcoplasmic Reticulum which stores the calcium needed for contraction and is the primary regulator of calcium in the VSM cell. The SR …
