(2010-09-02)Trends in wireless networks are increasingly pointing towards a future with multi-hop networks deployed in multi-channel environments. In this thesis, we present the design for iMAC—a protocol targeted at medium access ...
-
(2009-03-16)Automated recognition of object categories in images is a critical step for many real-world computer vision applications. Interest region detectors and region descriptors have been widely employed to tackle the variabili ...
-
(2011-06-16)The decrease of switching times accompanied by the corresponding increase of clock speeds and data rates, contributes to improve the overall system computational performance. At the same time, they also affect wireless ...
-
(2002-08-22)The wakeup logic in out-of-order superscalar microprocessors is responsible for resolving the data dependency hazard between instructions. Its performance is critical because it may prevent the processor to have deeper ...
-
(1990-06-27)Generalized Radial Basis Functions were used to construct networks that learn input-output mappings from given data. They are developed out of a theoretical framework for approximation based on regularization techniqu ...
-
(2003-01-24)Ad Hoc networks are multi-hop wireless networks consisting of mobile hosts. They do not have any pre-existing network infrastructure and are characterized by constantly changing topology, limited battery power and band ...
-
(2010-03-18)This paper provides a measurement-based performance evaluation of the Optimized Link State Routing (OLSR) protocol. Two versions of OLSR, OLSR-ETX and OLSR-ETT, are implemented and evaluated on a mesh network that we b ...
-
(2000-06-20)As the information-processing and telecommunications revolutions now underway will continue to change our life styles in the rest of the 21st century, our personal and economic lives rely more and more on our ability t ...
-
(1994-03-03)TASKMASTER is an experimental microcontroller node of a real-time control oriented network which was proposed by James H. Herzog and Tinggui Zhang to demonstrate the feasibility of a task oriented control structure in ...
-
(2005-10-17)Ultra-wideband (UWB) radio is the transmission of data using an extremely wide bandwidth and very low power spectral density. In this thesis, the mereits and challenges of UWB architectures versus conventional narrowban ...
-
(1990-10-10)As hardware becomes cheaper and cheaper, there is an increasing interest in the implementation of distributed control networks with microcontrollers. Such networks are usually inexpensive and of high performance. In ...
-
(1990-03-29)This thesis discusses an approach whereby Microsoft's MS OS/2 is provided with a means of running the Department of Defense's Transmission Control Protocol/Internet Protocol (TCP/IP). This is done by developing a Pac ...
-
(1996-03-15)Distance learning enables students to study effectively from remote locations. With televised lectures now commonplace, many disciplines can provide effective distance learning. While the lecture format serves many dis ...
-
(1997-06-27)This dissertation investigates the constraints which arise when switched-capacitor (SC) delta-sigma modulators are designed for low-voltage operation, targeting also low power dissipation, and proposes methods of impro ...
-
(2003-12-12)Switch-mode power supplies (SMPS's) not only convert energy, they also consume it. Typical operational efficiencies are approximately 25 to 60% for linear power supplies, and approximately 50-90% for switching power su ...
-
(1991-04-24)An improved robot manipulator decentralized non-linear adaptive controller that performs well in the presence of disturbances with unknown parameters and non-linearities is presented in this work. The proposed decentr ...
-
(1989-06-23)The stability of ZnS:Mn AC thin film Electroluminescence (ACEFEL) devices as demonstrated by the brightness-voltage (BV) characteristics is discussed. Two procedures for improvement of the stability are demonstrated. ...
-
(1992-04-30)Delta-Sigma Modulator-based Analog-to-Digital converter design is an active area of research. New topologies require extensive simulations to verify their performance. A series of improvements were made to an existing ...
-
(1997-06-09)Until now the topic of motion estimation, as used in video compression, has been dominated by search methodologies which are modifications of an exhaustive search. This research takes a completely new approach by applyin ...
