This paper presents a proposal of a context-based architecture to achieve the required synergy among the ubiquitous computing devices of an intelligent environment. These devices produce context information that models the behaviour of the environment. This context information is the glue among the devices and the context-aware applications. The generated context information provides a common v...

Although simple wireless communication involving nodes built of microcontrollers and radio devices from the low end of the price spectrum is quite popular these days, one seldom hears about serious wireless networks built from such devices. Commercially available nodes for ad-hoc networking (somewhat inappropriately called “motes”) are in fact quite serious computers with tens of megabytes of R...

More and more intelligent electronic devices (IEDs) are being installed and utilized in power system substations. Majority of these new devices come with event recording feature and some even provide fault location calculation. In case of power system faults, protection and fault analysis engineers are often presented with event recording coming from various substations and also from multiple d...

In this paper the concept of an ad hoc agent environment as a way for users to interact with an ambient intelligent environment is introduced. Utilizing agents, users can interact on a level that best suits their needs and capabilities, leaving tedious chores to the agents. The user interacts with this environment as a whole, instead of interacting with individual applications on individual dev...

If mobile computing is to become the predominant computer usage paradigm in the coming years as is widely anticipated, a substantial increase in the demand for mobile computing applications and services will arise. How best to engineer such applications remains an open question and is naturally the focus of much research. In this article, we propose the use of intelligent agents as the constitu...

Intelligent Optical Networks (IONs) allow setting up or tearing down lightpaths dynamically. The logical topology in multi-layer networks (such as IP-over-OTN scenarios) is supported by these lightpaths, and thus dynamically configurable. Consequently, traffic engineering functionality is extended with cross-layer capabilities, leading to multi-layer traffic engineering (MTE). This paper explai...

These days, the most important areas of research in many different applications, with different tools, are focused on how to get awareness. One of the serious applications is the awareness of the behavior and activities of patients. The importance is due to the need of ubiquitous medical care for individuals. That the doctor knows the patient's physical condition, sometimes is very important. O...

Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Measurement of solar radiance demands expensive devices to be used. Alternatively, estimator models are used instead. In this paper, a new method based on the empirical equations is introduced to estimate the monthly average daily global solar radiation on a horizontal surface. The proposed method uses Intelligent Water ...

This article proposes a mobile intelligent agentbased e-business architecture that allows buyers and sellers to perform business at remote locations. An e-business participant can generate a mobile, intelligent agent via some mobile devices (such as a personal digital assistant or mobile phone) and dispatch the agent to the Internet to do business on his/her behalf. This proposed architecture p...
