Received: 9 November 2008 Accepted: 22 November 2008 Abstract We present a novel collaborative visual analytics application for cognitively overloaded users in the astrophysics domain. The systemwas developed for scientists who need to analyze heterogeneous, complex data under time pressure, and make predictions and time-critical decisions rapidly and correctly under a constant influx of changi...

The need for improving the operation and control of infrastructure systems has created a demand for optimization and control methods applicable in the area of complex networked systems operated by a multitude of actors in a setting of decentralized decision making. Because of the analogy between production systems and infrastructures, process systems engineering (PSE) approaches for optimizatio...

It is expected that residential units may replace   traditional heat and power production systems with cogeneration ones. Among the different cogeneration systems, fuel cell based systems are a suitable choice due to their high efficiency, high power density, low emission and low noise. In this paper, a cogeneration system based on solid oxide fuel cells is examined. The system, including the f...

A study was conducted to evaluate the effects of two laying systems (floor versus cage) on egg production, egg quality, and microbial safety. One hundred and eighty 42 wk old laying hens were separated into two groups of 90 hens each, and housed in laying cages and a floor laying system. Eggs from the hens were collected for 2 weeks, and hen-day egg production, egg quality (whole egg, albumen, ...

The first motive for the determination and evaluation of an energy productionsystem is the need to change. Such system is dynamic in nature and is influenced bymany factors such as age and physiological status of individual sheep or goat, quantityand quality of available feed and environment including the management systems.Traditional pastoral resource assessments do not always account for the...
