In this paper, the authors investigate performance of a smart ESPAR (Electronically Steerable Passive Array Radiator) antenna with omni-directional and directional antennas. Performance of wireless network systems depends on the kind of antenna that is used. Every type of antenna has specific characteristics that determine gain, direction and bandwidth. Background of smart antennas has been ...

Similarity measurement of business processes is a basic operator which is useful in several scenarios, such as business process management, business process searching, business process re-engineering and so on. Firstly, the framework of the methodology is proposed; secondly, two kinds of trace generation method is discussed; thirdly, the measurement of trace similarity is studied from ...

Mainly, the authors focus on various queuing scheduling disciplines including Modified ...

The Artificial Intelligence (AI) applied in electronic games is known as Game AI (Game Artificial Intelligence), and its main purpose is to create a behavior which seems intelligent, due to a scenario with multiple choices. This should be similar to the human-being behavior with personality, making mistakes and be able to provide different levels of ...

A microcontroller is a computer-on-a-chip used to control electronic devices. It is a type of microprocessor emphasizing self-sufficiency and cost-effectiveness, in contrast to a general-purpose microprocessor (the kind used in a PC). A typical microcontroller contains all the memory and interfaces needed for a simple application, whereas a general purpose microprocessor requires additional chips to ...

Data warehouse is one of the key Information Technology (IT) infrastructures. Data warehouse involves a huge financial undertaking. It is important that data warehouse performance is measured in terms of some key aspects. A Balanced ScoreCard (BSC) approach could be applied to measure the performance of data warehouse operations. This paper discusses measurements of performance ...

Cloud computing, the long-held dream of computing as a utility, has the potential to transform a large part of the IT industry, making software even more attractive as a service. Cloud computing refers to both the applications delivered as services over the internet and the hardware and systems software in the data centers that provide ...
