Abstract:

In recent years, Multiple-Input-Multiple-Output (MIMO) techniques have attracted substantial attention due to their capability of providing spatial diversity and/or multiplexing gains. Inspired by the concept of Spatial Modulation (SM), the novel concept of Space-Time-Shift-Keying (STSK) was recently proposed, which is considered to have the following advantages: 1) STSK constitutes a generalized shift keying architecture, which is capable of striking the required trade-off between the required spatial and time diversity as well as multiplexing gain and includes SM and Space Shift Keying (SSK)

Abstract:

The first chapter of this thesis studies the effect of labor unions on the elasticity of substitution between production inputs in several transportation industries such as railroad, postal service and air transportation. The elasticity is derived from two different methods: the CES production function and the translog cost function. This study finds that labor unions lower the flexibility to substitute between labor and capital in the air transportation industry. The second chapter estimates the effect of using internet job search on labor market outcomes. This study uses a Cox Proportional H

This investigation was an attempt to replicate and expand previous research which suggested that laterality of electromyographic biofeedback input had a significant effect in lowering frontalis muscle activity.

This study was limited to one biofeedback session and subjects were selected based on demonstration of right hand/ear dominance. The purpose of

The manufacturing of components with complex internal features, e.g. for automobile industry, aeronautics or medical applications, is a significant challenge.

Abstract:

This dissertation addresses specific issues on domestic and foreign trade in India. The three chapters of the dissertation are summarized as follows. In the first chapter, we analyze the existence of regional wage differences across Indian states, and how domestic trade affects those premiums. We follow a two-step estimation process used in the literature on Labor Economics. Our empirical results show that higher level of domestic imports tends to reduce the state premiums, and higher domestic exports increase those premiums, which is consistent with a specific factor Ricardo-Viner model.

Abstract:

Relativamente a crianças monolingues, o uso mais prototípico do complemento direto preposicionado (o uso da preposição a para marcar a animacidade) dá-se antes dos três anos de idade (Rodríguez-Mondoñedo 2008). No entanto, poucos são os estudos que se debruçam sobre a aquisição deste fenómeno em crianças bilingues. A presente dissertação foca-se na aquisição do complemento direto preposicionado em crianças bilingues português europeu-espanhol ibérico, residentes em Portugal, com 4 e 5 anos. Foi utilizado um teste de produção induzida que considerava a variável animacidade, tendo em conta a esc

Abstract:

Neuronal communication in the mammalian brain relies on the presynaptic release of neurotransmitters which bind to ligand-gated ion channels found on postsynaptic neurons to modulate neuronal excitability. One such neurotransmitter is acetylcholine (ACh), a small molecule that is the signalling messenger of the cholinergic system. The cholinergic system is involved in a variety of behavioural functions including motor activity, sensory function, and higher executive commands. Dopaminergic neurons in the substantia nigra pars compacta (SNc) and the basal ganglia in general have long been implic

Abstract:

碩士<br>國立清華大學<br>電子工程研究所<br>97<br>In this work, TSMC SiGe0.35μm technology is used to design a low noise analog integrated circuit. This work is called 「Noise Improvement of Low-frequency , Low-power Rail-To-Rail Differential Input Op-Amp」, and is simulated by H-SPICE. It uses BiCMOS technology replacing CMOS technology in the differential input stage to improve noise in Op-Amp circuits. Through simulation and comparison, the results show that noise in the BiCMOS rail-to-rail differential input Op-Amp is better than noise in CMOS rail-to-rail differential input Op-Amp. Finally, rail-to-rail ins

Abstract:

It is well known that communication using multiple antennas provides high data rate and reliability. Coding across space and time is necessary to fully exploit the gains offered by multiple input multiple output (MIMO) systems. One such popular method of coding for MIMO systems is space-time block coding. In applications where the terminals do not have enough physical space to mount multiple antennas, relaying or cooperation between multiple single antenna terminals can help achieve spatial diversity in such scenarios as well. Relaying techniques can also help improve the range and reliability

Abstract:

L’Agenda Digitale Europea stabilisce il ruolo chiave delle tecnologie dell’informazione e della comunicazione (TIC) grazie a un mercato digitale unico basato su internet veloce e superveloce e su applicazioni interoperabili, al fine di ottenere vantaggi socioeconomici sostenibili COM(2010)245. Le TIC producono un'innovazione di prodotto e cambiamenti strutturali all'interno di tutto il sistema economico e possiamo affermare che dal punto di vista multisettoriale hanno un ruolo moltiplicativo sulla crescita economica, poiché l’aumento della domanda di TIC stimola a sua volta tutte le altre prod
