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:

This thesis considers the problem of robust geometric regulation for tracking and disturbance rejection of systems governed by delay differential equations. It is well known that geometric regulation can be highly sensitive to system parameters and hence such designs are not always robust. In particular, when employing numerical approximations to delay systems, the resulting finite dimensional models inherit natural approximation errors that can impact robustness. This demonstrates this lack of robustness and then addresses robustness by employing versions of robust regulation that have been d

We study the regularization problem for linear, constant coefficient descriptor systems $E x^. = AX + Bu, y_1 = Cx, y_2=\Gamma x^.$ by proportional and derivative mixed output feedback. Necessary and sufficient conditions are given, which guarantee that there exist output feedbacks such that the closed-loop system is regular, has index at most one and $E +BG\Gamma$ has a desired rank, i.e. there is a desired number of differential and algebraic equations. To resolve the freedom in the choice of the feedback matrices we then discuss how to obtain the desired regularizing feedback of minimu

<p>A method for rapid evaluation of flux-type outputs of interest from solutions to partial differential equations (PDEs) is presented within the reduced basis framework for linear, elliptic PDEs. The central point is a Neumann-Dirichlet equivalence that allows for evaluation of the output through the bilinear form of the weak formulation of the PDE. Through a comprehensive example related to electrostatics, we consider multiple outputs, a posteriori error estimators and empirical interpolation treatment of the non-affine terms in the bilinear form.

These actions tended to be slightly enhanced by MERGETPA. 3) The elimination of C3a plus C3adesArg immunoreactivity during a single liver passage

Abstract:

During the operation in a modern power distribution system, some abnormal events may happen, such as over-voltage, faults, under-frequency and overloading, and so on. These abnormal events may cause a power outage in a distribution system or damages on the equipment in a distribution system. Hence these abnormal events should be identified and isolated by protection systems as quickly as possible to make sure we can maintain a stable and reliable distribution system to supply adequate electric power to the largest number of consumers as we can.

Abstract:

碩士<br>淡江大學<br>電機工程學系碩士班<br>98<br>The geometrical shape of antenna arrays for maximizing the average channel capacity of the system in a multiple-input multiple-output (MIMO) link is investigated. The optimum element spacing of the transmitting antenna is also included. In this paper, channel capacity of multiple-input multiple-output narrowband system in indoor wireless channels at 5-GHz U-NII (Unlicensed-National Information Infrastructure) bands is calculated. An optimization procedure for the element spacing of the antenna transmitter in narrowband wireless communication system is presented

Abstract:

Questa tesi analizza le dinamiche qualitative e quantitative del modello di crescita economica Solow-Swan con differenti tassi di risparmio per lavoratori e capitalisti considerando differenti funzioni di produzione, al fine di studiare come le dinamiche di lungo periodo di un’economia sono influenzate dall’elasticità di sostituzione tra i fattori della produzione e da differenti propensioni al risparmio. Nel primo capitolo è discusso il problema di stabilire una relazione tra elasticità di sostituzione ed i livelli di capitale ed output pro capite quando si considera una funzione di produzio

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
