    Thin-film copper membranes on silicon substrates were constructed using micromachining techniques. Membranes possessed surface corrugations 10 µm deep and ranged in size from 1.04 mm to 10.0 mm in diameter. Membranes were released using a combination of both KOH and xenon difluoride (XeF ) backside etching. Surface corrugations were made using KOH etching on the frontside of the wafer. The me...

  • Analogue integrated circuit sizing with several optimization runs using heuristics for setting initial points

    Circuit sizing (i.e., determining MOSFET channel widths and lengths which result in the most appropriate and robust circuit) is an optimization process. When it is completed, there always remains a dilemma; namely, whether a better solution exists. With different starting points one can arrive at different local minima. A heuristic process, consisting of many optimization runs starting from differ... View full abstract»

    An integrated approach is presented for uplink and downlink air interface capacity evaluation and traffic analysis for the multiservice Universal Mobile Telecommunications System (UMTS). Within this framework the effects of both soft handoff (SHO) and fast power control (FPC) are considered. The canonical capacity of any given service, defined as the maximum number of concurrent users of that serv... View full abstract»

    In this paper a new, reduced-complexity algorithm for multistage detection of direct-sequence code division multiple access (DS-CDMA) signals in additive white Gaussian noise (AWGN) channels is presented. Bit error rate performance of the new algorithm is determined via Monte Carlo simulation, and it is shown that the new algorithm, although designed to reduce computational complexity, performs be...

    In this paper a microprogrammable-processor teaching tool and its FPGA implementation are presented. The processor is based on a classical Am2900 architecture and is implemented in the popular Xilinx Foundation" environment. The tool helps electrical and computer engineering students to become familiar with microprogramming through development of their own instruction sets and experiments with sig... View full abstract»

  • Power spectral density of a UWB signal with discrete quantized pulse positions

    The FCC specification for ultra-wideband (UWB) emissions states that the effective isotropic radiated power (EIRP) cannot exceed 41.3 dBm per 1 MHz bandwidth in the frequency region of 3.1 to 10.6 GHz. Hence, to achieve adequate transmit power in a UWB data link it is necessary to use a wide-bandwidth modulation scheme. This requirement presents a pair of technical challenges which are addressed i... View full abstract»

    This study reports on the design, fabrication, testing, and mathematical modelling of a semiconductor microstrain-gauge endoscopic tactile sensor. The sensor can measure, with reasonable accuracy, the magnitude and the position of an applied load on a grasper. The designed assembly consists of two semiconductor microstrain-gauge sensors, which are positioned at the back face of a prototype endosco... View full abstract»

    This article presents a simple method for calculating the signal toi nterference-plus-noise ratio in direct sequence code division multiple access systems with despreading sequences weighted by stepping chip waveforms. The method is based on a simple equality, which gives a relation among the number of occurrences of various chip patterns belonging to random spreading sequences. It is found that t...

  • A simple and fast algorithm for determining asymptotic stability of linear autonomous systems

    The method introduced here determines explicitly whether a given system has only eigenvalues with negative real parts, without determining these eigenvalues, but rather by determining the eigenvalues of a related symmetric matrix which are always real and hence easy to calculate. The new method is similarly applied to linear autonomous discrete systems where all the eigenvalues of the system matri... View full abstract»

    In this paper a new method is developed for obtaining necessary and sufficient conditions which, when satisfied, guarantee that a linear non-autonomous system will be uniformly asymptotically stable. The method is essentially an extension of two earlier theorems on the asymptotic stability of linear autonomous systems; these theorems, developed by the same author, are here extended to non-autonomo...
