Worst month rain statistics measurement in Malaysia
- Trang 12-14
Excess attenuation due to rainfall is one of the most important constraints to the performance of microwave radio links. In temperate climates at frequencies above 10 GHz, rainfall rates have significant effects on the performance of microwave radio links. Therefore, the behavior of radio communication links varies seasonally over a year. This paper presents on the results obtained from the analys......

Ternary decision diagrams
- Trang 76-79
TDD graph-based representation is actually a natural extension of the binary decision diagram (BDD) to the three-valued case. This paper describes a method of defining, analyzing, and implementing the Boolean function using a ternary decision diagram (TDD). This diagram representation enables us to evaluate a Boolean function. We investigate the characteristics of different types of TDDs in order ......

Vibration faults simulation system (VFSS): a system for teaching and training on fault detection and diagnosis
- Trang 15-18
Machine condition monitoring is vital in many plants as any shutdown can lead to both materials and financial losses. Since vibration fault signals and their causes are important for fault detection and diagnosis, a vibration faults simulation system (VFSS) is developed to gain good understanding of vibration faults signals. This paper is aimed at simulating and analyzing vibration fault signals, ......

Reliable multicast service with IPv6 support: synchronous collaborative applications
- Trang 468-471
The world wide web (WWW) already accounts for more Internet network traffic than any other application, including email and simple file transfer. It is also a collaborative technology in a weak sense of the word - it allows people to share information. Synchronous collaboration is where an interactive activity is simultaneous and in real-time. Computer based synchronous collaborative systems like ......

Electromagnetic simulation of the effects of dielectric and metal thicknesses on the performance of multilayer MMIC lowpass filter
- Trang 418-421
The authors report on the effects of dielectric and metal thicknesses on the performance of a multilayer monolithic microwave integrated circuit (MMIC) lowpass filter. An electromagnetic simulator, Sonnet, is used to characterize and predict the effect of both factors on the filter response. Results of this simulation show that the filter operates with optimum performance when the metal and polyim......

Tổng quan về hạ tầng mạng di động 3G Dịch bởi AI
- Trang 228-232
Sự chuyển đổi từ hệ thống di động thế hệ thứ hai (2G) sang thế hệ thứ ba (3G) (ví dụ: từ GSM sang UMTS) đang diễn ra tại Châu Âu và khu vực Châu Á - Thái Bình Dương. Các nhà điều hành 3G đang triển khai cơ sở hạ tầng mới để cung cấp dịch vụ Internet di động cho người dùng cuối. Ericsson cam kết thực hiện chuyển đổi này một cách thuận lợi nhất có thể cho các nhà điều hành và người dùng cuối. Bài bá......

A comparison of microwave propagation models and evaporation duct height estimation techniques with actual near water atmospheric and radio data taken in North Queensland, Australia in May 2001
- Trang 120-123
For a number of years, RSRG, together with DSTO and JCU, has been taking measurements of radio propagation inside the evaporation duct using large arrays together with near ocean measurements of atmospheric refractivity. This paper presents results from such experiments carried out in May 2001. The authors collected a vertical profile of received signal strength from a transmitter 18 km away, prop......

Phân tích tải trong thị trường điện mới Dịch bởi AI
- Trang 278-281
Ngành điện đã sử dụng các biểu đồ tải, đặc biệt là trong việc xây dựng biểu phí, trong nhiều năm. Tuy nhiên, việc sử dụng các biểu đồ tải trong thị trường điện mới là một sự phát triển mới và khác biệt. Trong một môi trường năng lượng phi huy động, khách hàng có thể mua điện từ bất kỳ nhà cung cấp nào mà không cần quan tâm đến quy mô và vị trí. Do đó, ngày càng có sự quan tâm đến việc hiểu bản chấ......

Evaluation of multicasting in WDM optical network
- Trang 257-260
In this paper, we evaluate the performance of multicasting in a single-hop local lightwave network based on a broadcast-and-select system. We use an approximate analytical solution and Markov model to show the effect of tuning time on the average packet delay and offered load. We also show the trade-off between the average packet delay and the number of wavelengths for the network.

Loan assessment through Internet
- Trang 480-483
This technical paper presents aspects of Web-based applications using JavaScript (JScript) and Visual Basic Scripting Edition (VBScript). By integrating JScript and VBScript into HTML pages, it can make elements of the Web page respond to user action. This paper focused on developing a Web site about loans, specifically national car loans through an intranet or the Internet using any Web browser. ......
