Fluorescence based methods are increasingly being used for the analysis of crude oils because they offer high speed, low cost, non-contact, and non-destructive testing options. The fluorescence of crude oils is due to the presence of a wide range of cyclic aromatic compounds, with the intensity and temporal behaviour of this fluorescence being directly related to chemical composition. In partic...

BACKGROUND Estimates of lifetime cancer risk are commonly used in the clinical setting and in health-care evaluations. These measures are based on lifetime cancer risk estimates and may create an unrealistically frightening perception of cancer risk for an individual. We suggest using two new measures of cancer risk to complement the cancer lifetime risk measure, namely estimates of cancer risk...

background: the brown-banded cockroach, supella longipalpa , is not as common as the german cockroach in iran. this species seeks out areas that are very warm most of the time, and prefer warmer area than what german cock­roaches pre­fer. there is relationship between development of instars and diet of cockroaches. the aim of this study was to determine the effect of different diets on biology,...

Increasing lifetime in wireless sensor networks is a major challenge because the nodes are equipped with low power battery. For increasing the lifetime of the sensor nodes energy efficient routing is one solution which minimizes maintenance cost and maximizes the overall performance of the nodes. In this paper, different energy efficient routing techniques are discussed. Here, photovoltaic cell...

A sensor network consists of many low-cost, low-power, and multifunctional sensor nodes. One of the most important issues in sensor networks is to increase network lifetime, and there have been researches on the problem. In this paper, we propose a routing mechanism to prolong network lifetime, in which each node adjusts its transmission power to send data to its neighbors. We model the energy ...

In this paper, we study the operational semantics of agent communication languages.We develop a basic multi-agent programming language for systems of concurrently operating agents, into which agent communication languages can be integrated. In this language, each agent has a mental state comprised of an informational component and a motivational component; interaction between the agents proceed...

Expansion of software systems in size and complexity during its lifetime business process models has to change to provide analytical insights, to improve and optimize business processes. Business process is always managed, self-adapting and evolving instance. But system management needs additional resources. This paper focuses on enterprise software system integration solutions that had been ev...
