Fox, Jason Cho. "Transient Melt Pool Response in Additive Manufacturing of Ti-6Al-4V." Research Showcase @ CMU, 2015. http://repository.cmu.edu/dissertations/746.

Abstract:

Additive manufacturing (AM) processes are candidates for manufacturing and repair in the aerospace industry. For process stability, control of melt pool dimensions is imperative. This can be achieved via feedback and/or feedforward control approaches; however, the time needed for a change in process variables (beam power and travel velocity) to translate into changes in melt pool dimensions is a critical concern. Prior works have determined the relationship between process variables and melt pool geometry, which can be monitored in situ for feedback control. In the current work, Ti-6Al-4V is s

Abstract:

Vat photopolymerization (VP) is an additive manufacturing (AM) technology that permits the fabrication of parts with complex geometries and feature sizes as small as a few microns. These attributes make VP an attractive option for the fabrication of scaffolds for tissue engineering. However, there are few printable materials with low cytotoxicity that encourage cellular adhesion. In addition, these resins are not readily available and must be synthesized. A novel resin based on 2-acrylamido-2-methyl-1-propanesulfonic acid (NaAMPS) and poly(ethylene glycol) diacrylate (PEGDA) was formulated and

Fenugreek (Trigonella foenumgraecum) is a member of the legume family and is found in India, Middle East, North Africa and South Europe. Fenugreek is used as an herb in traditional medicine to promote lactation in lactating women. It also influences the lactation performance in ruminants such as dairy cows, water buffaloes and dairy goats. Diocin is a natural saponin found in Fenugreek and has structural similarity to oes

Electrochemical quartz crystal microbalance has been employed to investigate electro-responsiveness of an ionic liquid as an additive in lubricant oils on a gold surface. Polarisation of the surface reveals changes in frequency where an increase in magnitude amplified the observed response, corresponding to a controllable alternation of the ionic liquid configuration on the surface as a function of applied potential. The frequency changes are due to different packing of the anion and cation, respectively, on the surface as their mass densities and geometries are different. Relaxation of the sy

Abstract:

Sudden changes in nutrient resources are common in the natural environment. Cells are able to adapt and propagate under changing environmental conditions by making adjustments in their cellular processes. These cellular adaptations involve genome-wide transcriptional reprogramming that results in the induction or repression of metabolic pathways. Specific enzymes are then synthesised and activated to maximise the use of the newly available nutrient sources. L-serine is one of the twenty proteinogenic amino acids, and can be synthesised in yeast by the glycolytic and gluconeogenic p

Higher PTPF and lower proof time significantly (P<0.05) reduced the brightness of bread crumb. Crumb firmness was influenced by the PTPF, water level and proof time.

Among these infections, one of the most difficult to be eradicated is coccidiosis, a major concern for poultry production in terms of reduced performance and high mortality. With costumers’ concern about the use of antibiotics in animal feeds, the ban of antibiotic growth promoters in the European Union, and the development of antibiotic – resistant coccidia, it is imperative to find alternatives for the control of this parasite. Probiotics have been shown to en

碩士<br>國立中山大學<br>材料與光電科學學系研究所<br>104<br>There is no doubt that additive manufacturing (AM) has been widely applied in industries with high additional values, like industrial design, medicine and aerospace industry. Among of these three applications, medicine industry has the harshest standard. As AM technique, through the secondary processes is a kind of disadvantage to it, it is still necessary to get the proper properties for the harsh standard of biomaterial. This study contains two parts. For the first study part, it is intended to let the as-fabricated SLM (selective laser melting) samples

There are two ways to increase the stability of emulsions. One is through surface modified particles, and the other is combining the solid particles with surfactant. Compared with the traditional emulsions, Pickering emulsions are more stable, in which the amount of surfactant is reduced. Therefore, Pickering emulsions tend to have low pollution for environment, and it has great potential for applications. The emulsions were prepared by adding

Abstract:

Experiments were conducted to evaluate the ability of prebiotic and probiotic supplementation of commercial fish feed to improve the physiological, immunological, and growth responses of stressed Nile tilapia. To investigate these objectives, tilapia were divided in two major groups: control fish (fed regular commercial feed) and stressed fish (induced by dietary cortisol supplemented to regular commercial feed). Stressed fish were further divided into three sub-groups: stressed fish fed regular feed, stressed fish fed probiotic-supplemented feed, and stressed fish fed a mixture of prebiotic a

碩士<br>國立臺中教育大學<br>教育測驗統計研究所<br>100<br>ABSTRACT Cognitive diagnostic testing is very important at a teaching scene. And whether testing results can represent students’ true abilities is even more important. Currently, most computer diagnostic tests are composed of mainly multiple-choice questions. However, students may guess correct answers, influencing accuracy of tests. This study designed two test papers with the “score adding and subtracting” section. One test paper contains all multiple-choice questions and the other contains constructed-response questions. Also an automatic analysis mecha
