Abstract:
Reliable and stable processes allowing precision manufacturing are a core demand in today’s production. To achieve stable processes several influences on machine tools have to be controlled. Beside the other factors, thermal influences are among the most important factors infecting the production system.In this work two problems that are caused by thermal deviations are considered: Firstly the positioning error of machine tools, and secondly possible changes in the elastic behaviour of a machine tool due to changes in stiffness.Positioning problems due to thermal changes are widely examined in

Abstract:
Stability of biological substances based on proteins, including vaccines, antibodies, and enzymes, is critically linked to its thermal environment. Temperature stress over time results in protein denaturation. Denaturation is a loss of structure and function in proteins. Their storage and distribution therefore relies on a “cold chain” of continuous refrigeration, which is costly and not always effective in medical and biological applications. Due to this issue, access to insulin for treating diabetes is still beyond the reach of millions of people around the world [1]. Diabetes is predicted t

Metallic glass is a class of materials which have a disordered structure of atoms, due to this, glasses lack grains and grain boundaries, which are present in their crystalline counterparts. Metallic glasses have many interesting properties worth investigating, such as high corrosion resistance or high mechanical strength. However, metallic glasses are metastable and will therefore crystallise if heated above the crystallisation temperature.

Abstract:
Nanocrystalline bainite, commonly known as “superbainite”, is a novel class of steel that utilises careful alloy design to reduce the bainite transformation temperature to below 300℃. This results in grains that are tens of nanometres in width, which make steel strong and tough. The structure can be produced in large volumes without the need for rapid cooling or severe deformation. The presence of austenite in nanocrystalline bainite is largely responsible for the toughness. Unfortunately, the austenite is metastable and previous work has shown that it decomposes into cementite and ferrite upo

D.)--Massachusetts Institute of Technology, Dept. of Mechanical Engineering, 2012.<br>Cataloged from PDF version of thesis.<br>Includes bibliographical references (p. 97-103).<br>A fundamental challenge in solar-thermal-electrical energy conversion is the thermal stability of materials and devices at high operational temperatures. This study focuses on the thermal stability of tungsten selective emitters for thermophotovoltaic (TPV) systems which are anticipated to enhance the conversion efficiency. Selective emitters, 2-D photonic crystals, are periodic micro/nano-scale structures

Abstract:
In order to obtain diamond-like carbon (DLC) thin films with improved mechanical, tribological, thermal and corrosion properties for practical applications, the structure and properties of various DLC thin films including hydrogen-free DLC, hydrogenated DLC, and DLC-MoS2 composites synthesized under different conditions were investigated in this thesis. The research methodologies and the main results are summarized in following paragraphs. Hydrogen-free DLC thin films were synthesized by biased target ion beam deposition (BTIBD) method, while hydrogenated DLC thin films were deposited by ion b

碩士<br>國立清華大學<br>生命科學系<br>91<br>For all the information needed to create thermal tolerance is encoded in the protein sequence as proteins of both thermalphiles and mesophiles are composed of the same 20 amino acids. Predicting sequence-depend changes in protein stability is one of the greatest challenges in molecular biology and bioinformatics. The number of protein sequences is exploding as a result of genome and other sequencing projects, and the increasing number of protein is much greater than the increasing number of known protein structures. In this work, we use classical statistical meth
