Abstract:

This thesis offers an overview of the representational politics of the online antifeminist community known as the ‘manosphere’. It analyzes how gender and gender politics are represented in the discourse, with an eye to how traditional gender constructs, and traditional gendered norms and inequalities, are reproduced. This project—the first study to focus exclusively on the manosphere—contributes to our understanding of the community in two ways; it addresses a significant gap in the literature on the topic, and it tests the accuracy of the ‘conventional wisdom’ on the manosphere.

Abstract:

Pick and Place (PnP) machines collect and use large amounts of image data of Printed Circuit Board (PCB) components. The data is used to train automated image analysis methods to improve the decisions in the mounting process. Previous work with Neural Networks has shown promising results in the classification of the component status. However, the characteristics of the data changes over time as new PCBs, components, and PnP machines are deployed. This work applies a Semi-supervised Domain Adaptation method named Associative Domain Adaptation to enable learning of a new and unlabeled data set.

Acoustic levitation is a versatile and promising tool for object manipulation that has been improved signicantly in recent years. This master's thesis explores the potential use of acoustic levitation in surface-mount technology. By coordinating several ultrasonic transducers an acoustic eld can be generated that can lift and manipulate small bodies without any physical contact. Earlier research in the area has demonstrated dierent arrangements for how the transducers can be placed. Two of these methods, each with 256 transducers, have been built and compared during this project. One arrangeme

Pick-up lines are a "ritual that tries to turn strangers into lovers" (Murray, 1985, p.17). By studying how pick-up lines are perceived by the population, we might learn how the phenomenon of short- or long-term mating is initiated. By taking into account mating strategies, mate value, attractiveness, and flirting strategies, a pattern of behaviors and reactions may be observed. This study examines perceived pick-up line appropriateness and effectiveness when the attractiveness of the man delivering them varies.

Abstract:

碩士<br>中原大學<br>機械工程研究所<br>84<br>Die pick and place machines are very important mechanical instruments in IC assembly industry. The production of die pick and place machine needs very high R&D technology. Until now, there is no any product developed by the domestic industry. Due to the IC market will grow fast in the future, this study proposes the research on the design, fabrication and performance evaluation of a high precision die pick and place machine. Based on an integration study of th

碩士<br>國立高雄應用科技大學<br>模具系碩士在職專班<br>105<br>This paper discusses the improvement on automation gripping mechanism in insert injection molding process. The existing gripping system is assembled by the grippers and the cylinders; the number of grippers is the same as cavities, meanwhile, the quantity of cylinders and pneumatic pipes are large, also the layout is very complicated. To simplify and improve the gripping system for more cavities of tooling in the future, the 1st edition of design uses commercially-available cylinder with self-manufactured gripper, minifying the size and decreasing the in

Abstract:

碩士<br>輔仁大學<br>物理學系<br>94<br>Abstract Micro-optical elements can be refractive, diffractive or hybrid (refractive/diffractive). The design of diffractive optical lenses provides more parameters to adjust the shape of wavefront, but its drawback is the strong negative dispersion. Diffractive optics are therefore mostly used with single color light. For broadband applications, DOE (diffractive of element) is combined with refractive optics to correct for the chromatic aberration. The combination allows systems with low weight, or which consist of only one material. DOE has not been largel

The human workers have to bend over to pick up the ripen fruits from the ground and collecting in the buckets. The main purpose of this research is to develop a pick-up machine for passion fruit to improve the efficiency of the labor-intensive work during harvesting and solve the problem of labor shortage. The impact recording device (IRD) was used to simulate the fruit dropped to ground when matured, then were collected by the developed ha

Abstract:

碩士<br>國立交通大學<br>電機與控制工程系所<br>95<br>There are many different gray scale mask fabrication processes in gray scale mask, such as half tone mask, high energy beam sensitive (HEBS) glass gray scale mask, and laser direct write (LDW) glass gray scale mask. They are attractive recently due to the simple photolithography process. Because the price of the HEBS glass and LDW glass is too expensive, the professional film is used to produce the gray levels by a DVD optical pick-up head. The DVD optical pick-up head in this thesis is composed of the tracking actuator, the focusing actuator, the objecti
