An intelligent universal virtual laboratory (UVL)
- Trang 75-80
M. Duarte, B.P. Butz
The objective of this project is to create a realistic, real-time, electrical engineering virtual laboratory for the use of disabled students. This project targets individuals who do not have adequate mobility of their upper bodies to perform laboratory experiments. To provide a more realistic and enhanced learning experience, the users of the virtual laboratory are allowed the freedom to build an... hiện toàn bộ

Kiểm soát phát điện tự động trước và sau khi giải phóng thị trường Dịch bởi AI
- Trang 321-323
N. Bekhouche
Bài báo này đề cập và thảo luận về cách thức mà Kiểm soát Phát điện Tự động (AGC) được hình thành trước và sau khi giải phóng thị trường. AGC là một trong số các dịch vụ được gọi là dịch vụ hỗ trợ, được định nghĩa bởi Ủy ban Điều tiết Năng lượng Liên bang Mỹ (FERC). Để cho phép truy cập truyền tải mở và khuyến khích một thị trường điện lực bán buôn cạnh tranh, việc giải phóng thị trường đã được FE... hiện toàn bộ

Stability of false lock states in a class of phase-lock loops
- Trang 133-137
J. Stensby
False lock is a practical, often very perplexing, problem in phase-lock loops (PLLs). When false lock occurs, the PLL may appear to be operating nominally; the phase detector output may have a nominal (usually small) average value, and a conventional lock detector may indicate a correct phase lock state. However, a static average frequency error exists in the loop. While stable false lock states a... hiện toàn bộ

Adaptivity on an OFDM fixed wireless access system
- Trang 458-462
A.D. Valkanas, P.I. Dallas, G.J. Karachalios, A.D. Poularikas
A special characteristic of multicarrier modulation techniques such as OFDM is that they can assign different modulation schemes to each subcarrier according to a reception quality measurement such as the signal-to-noise ratio (SNR) on a subcarrier. This process allocates different bits to subcarriers and is further known at the literature as bit loading. In the paper, a bit-loading algorithm has ... hiện toàn bộ

Survey of branch prediction schemes for pipelined processors
- Trang 324-328
K. Thangarajan, W. Mahmoud, E. Ososanya, P. Balaji
Branch prediction schemes have become an integral part of today's pipelined processors. They are one of the key issues in enhancing the performance of pipelined processors. Pipeline stalls due to conditional branches are one of the most significant impediments to realizing the performance potential of deeply pipelined and superscalar processors. Many schemes for branch prediction, that can effecti... hiện toàn bộ

Comparison of CORDIC algorithm implementations on FPGA families
- Trang 192-196
S. Vadlamani, W. Mahmoud
This paper presents different implementations of CORDIC algorithm on two field programmable gate array (FPGA) families, namely Xilinx XC4000XLA and VIRTEX series. Pipelining is used to improve the throughput and speed of the design. Xilinx foundation computer aided design (CAD) tools are used for synthesis, simulation and implementation on the FPGAs. A comparative study on the performance of these... hiện toàn bộ

Discrete wavelet transform domain adaptive decision feedback equalization
- Trang 243-247
A. Ghobrial, R. Adhami
In this paper we apply discrete wavelet transform processing to the decision feedback equalization adaptation problem. In particular, the discrete wavelet transform decision feedback equalizer (DFE) performance and complexity are compared to those of the least mean squares (LMS) and recursive least squares (RLS) algorithms. We illustrate, using a simulation example, that the wavelet transform DFE ... hiện toàn bộ

Passive compliance synthesis
- Trang 214-218
R.G. Roberts, E. Fabre
In this article we survey some recent work on the problem of realizing a spatial stiffness matrix with a parallel connection of springs. The techniques described here can be used to realize an arbitrarily specified stiffness dominated spatial impedance through the use of a mechanism constructed of passive springs. The article includes a discussion on how to rind an optimal realization of a positiv... hiện toàn bộ

Augmented proportional navigation guidance using subspace-stabilization
- Trang 471-475
C. Tournes, C.D. Johnson
The paper is concerned with the application of subspace-stabilization control theory to the missile guidance problem. In particular, the system error-state vector is stabilized to a certain subspace of the error state-space such that zero predicted miss-distance is achieved. The proposed control technique is related to the classical proportional navigation and augmented proportional navigation gui... hiện toàn bộ

A nonlinear flight controller design for a UFO by trajectory linearization method. II. Controller design
- Trang 103-107
Xiaofei Wu, T. Adami, J. Campbell, G. Jianwei, J.J. Zhu
For part I, see ibid., p.97-102 (2002). We present an attitude controller design for a 3 DOF flight control experiment apparatus, the Quanser UFO, as an application of the multi-input, multi-output (MIMO) nonlinear tracking and decoupling control technique based on a trajectory linearization method. The controller consists of two parts: a pseudo-inverse of the plant that computes the nominal contr... hiện toàn bộ
