Prototype design of a personal static VAr compensator
- Trang 311-315
A prototype personal static VAr compensator (PSVC) has been designed and implemented for load power factor correction for both residential and commercial applications. The PSVC demonstrates the two key benefits of power factor correction, which include decreased power costs and increased system capacity. The PSVC also demonstrates conventional static VAr compensator (SVC) principles that are routi......

Base-case power flow model of an interconnected power system
- Trang 316-320
This paper presents a user-friendly software in modeling daily base case by including the peak power interchange, forecast loads, scheduled generator, and transmission line outages. In order to model an interconnected power system accurately, the items mentioned above must be included into the base case before running the contingency screening. This software will abstract all downloaded files from......

Improved performance of space-time block codes on Rayleigh fading channel
- Trang 128-132
Using two transmit antennas and one receive antenna, Alamouti's schemes (1998) provide the maximum possible diversity gain with a maximum likelihood detector. In addition to diversity gain, this paper maximizes the coding gain using the minimum of the determinants of the code difference matrices. In order to achieve the maximum coding gain on a Rayleigh fading channel, a trellis code is designed t......

Electromagnetic modeling and design of broadband spatial power combiners
- Trang 108-112
In this paper we present a spatial power combining architecture consisting of several interacting printed antenna arrays placed at dielectric interfaces in multilayered waveguide. Previously used narrowband resonant patch and slot antennas are replaced by tapered meander slot antennas and their modifications, in order to increase the frequency bandwidth and efficiency of the system and provide ope......

Performance of noise canceller using adjusted step size LMS algorithm
- Trang 248-250
An adjusted step size LMS (least mean squares) algorithm is proposed for possible improvements in the performance of adaptive FIR filters in nonstationary environments. Nonstationary signals means that the statistical properties of the noise changes in time such as the high frequency channel time variations. In the paper, an adaptive noise canceller is proposed which is based on signal to noise ra......

Trích xuất phần cứng song song trong quá trình chuyển đổi C sang VHDL Dịch bởi AI
- Trang 334-338
Việc chuyển đổi ngôn ngữ C/C++ sang VHDL là một bước quan trọng trong việc tổng hợp phần cứng từ C/C++. Tuy nhiên, ngôn ngữ C/C++ thông thường không có cơ chế công khai để khai báo việc thực hiện song song đồng thời, một đặc điểm quan trọng của các hệ thống phần cứng. Bài báo này trình bày phác thảo của một tập hợp các thuật toán chuyển đổi. Những thuật toán này hữu ích trong quá trình trích xuất ......

Steering controller design using scale-model vehicles
- Trang 476-478
A scale-model, experimental apparatus is developed to design and evaluate steering controller designs. The controller is designed using linear quadratic optimal control methods on a standard four-state vehicle model. The apparatus simulates the human driver using a scale-model vehicle, a treadmill, and a vision system.

Documentation framework for computer network design reviews
- Trang 11-14
A documentation framework is proposed to assist quality assurance teams in the analysis of complex computer network designs. The framework includes three elements: (1) a requirements definition, (2) a design depiction, and (3) the identification of potentially problematical interfaces. Requirements definition begins with nominal statements describing general design requirements; these statements u......

Reusable launch vehicle attitude control using a time-varying sliding mode control technique
- Trang 81-85
We present a time-varying sliding mode control (TVSMC) technique for reusable launch vehicle (RLV) attitude control in ascent and entry flight phases. In ascent flight the guidance commands Euler roll, pitch and yaw angles, and in entry flight it commands the aerodynamic angles of bank, attack and sideslip. The controller employs a body rate inner loop and the attitude outer loop, which are separa......
