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...

Bộ điều khiển tốc độ nhị phân cho động cơ không đồng bộ ba pha Dịch bởi AI
- Trang 200-203
Động cơ không đồng bộ ba pha là loại máy phổ biến và được sử dụng rộng rãi trong
ngành công nghiệp. Một động cơ không đồng bộ về cơ bản là động cơ có tốc độ
không đổi, tuy nhiên trong nhiều ứng dụng, cần thiết phải có nhiều tốc độ hoặc
một dải tốc độ có thể điều chỉnh liên tục. Mục tiêu của dự án này là áp dụng một
phương pháp mới gọi là kỹ thuật nhị phân để điều khiển tốc độ của động cơ không
đồn...

Fingerprint identification and recognition using backpropagation neural network
- Trang 98-101
Biometrics is a technology which identifies a person based on his physiology or
behavioral characteristics. Fingerprint identification and recognition is a
biometrics method that has been widely used in various applications because of
its reliability and accuracy in the process of recognizing and verifying a
person's identity. The main purpose of this paper is to develop a fingerprint
identificati...

Development of simple PWM inverter using photovoltaic cells
- Trang 297-300
This paper presents the development of a simple 1.5 kW single-phase sinusoidal
pulse width modulation (PWM) inverter. This inverter is designed to be either a
stand-alone or grid connected inverter from a direct supply of photovoltaic (PV)
cells. The developed inverter unit converts the DC input supply from the PV
cells into a clean sinusoidal voltage output. This power inverter is also
capable of...

Radio resource and mobility management in GPRS network
- Trang 132-135
The General Packet Radio Service (GPRS) is a complex data network which upgrades
current second generation GSM networks, offering true high-speed Internet (IP)
and X.25 network connectivity over existing GSM cellular networks. The key
benefits of GPRS are better use of radio and network resources and completely
transparent IP support. The increasing population of mobile users leads to
congestion p...

Deploying Internet Protocol version 6 (IPv6) over Internet Protocol version 4 (IPv4) tunnel
- Trang 109-112
Internet Protocol version 6 (IPv6) or IP next generation is the protocol that
has been designed to replace the existing Internet Protocol version 4 (IPv4).
These two protocols are expected to coexist for a number of years during the
transition period. A number of IPv4-to-IPv6 transition tools are available to
address the various needs of different networks. The two most basic transition
tools avai...

Flight schedule query system based on natural language processing
- Trang 80-82
Natural language processing is part of the artificial intelligence domain.
Basically, natural language is the language used everyday in our communication
either in the form of writing or speech. Thus, this paper attempts to apply
natural language to a machine (computer), so that it can be processed and
interpreted in a human-like manner. However, up to now, this goal has not been
achieved. This re...

Consumer preferences for energy efficient room air conditioner in Malaysia: a conjoint approach
- Trang 282-285
In order to ensure the success of energy efficiency standards and labeling
program, a detailed consumer analysis of the room air conditioner market should
be carried out. It is essential to know what factors influence preferences for
room air conditioner, so that a program can be devised to increase the market
share for an energy efficient room air conditioner. Previous researchers
typically have ...

Một phương pháp phân đoạn bàn tay sử dụng kỹ thuật phân cụm trong nền đồng nhất Dịch bởi AI
- Trang 305-308
Phân đoạn hình ảnh là bước đầu tiên trong bất kỳ phân tích hình ảnh nào và nó
đóng một vai trò rất quan trọng vì sự thành công của phân tích hình ảnh ở các
giai đoạn sau phụ thuộc rất nhiều vào một sơ đồ phân đoạn phù hợp và ổn định.
Phân đoạn bàn tay, mặt khác, là bước đầu tiên cho phân tích hình ảnh bàn tay như
nhận diện cử chỉ bàn tay. Một phương pháp trừ hình ảnh được áp dụng cho hình ảnh
ở mứ...
