The electricity demand is continuously increasing, so a most efficient use of the current power system's capacity desired. Flexible AC Transmission Systems (FACTSs), recently developed transmission technology, are widely used to boost transfer ability long-distance line networks and enhance consistency systems. FACTS devices can lead reduced flows on heavily loaded lines, targeted bus voltage l...

The paper addresses the issue of stability for re-entrant flow lines, producing multiple products, with capacitated machines, random demand and random yield. The policies of interest are multi-echelon base stock policies, combined with a set of static and dynamic management rules of the available capacity. We introduce three classes of capacitated echelon base stock policies: Π0, the pure multi...

Flexible plants, fungi and sessile animals reconfigure in wind and water to reduce the drag acting upon them. In strong winds and flood waters, for example, leaves roll up into cone shapes that reduce drag compared with rigid objects of similar surface area. Less understood is how a leaf attached to a flexible leaf stalk will roll up stably in an unsteady flow. Previous mathematical and physica...

We present a model and analysis of a production line that processes different part types on unreliable machines which operate according to a priority rule. The production line consists of machines separated by storage areas in which parts flow in a fixed sequence. A machine operates on the highest priority part whenever possible, and only operates on lower priority parts when unable to produce ...

AMACOIA (for Approche Multi-Agents pour la COnception d’Installations d’Assemblage) is a tool for designing flexible assembly lines. Its objective is to determine the functional specifications of the constituting equipments (manipulators, fixtures, grippers, conveyors, ...) and the organisational structure (cells, workstations) for the least expensive assembly line able to assemble a product (o...

Software Product Line development entails planned reuse of development assets for creating applications in a specific domain. SPL development can benefit from incorporating soft constraints in both Domain and Application Engineering. Increased expressiveness is attained and important domain knowledge that would otherwise be lost can be included, allowing improved configuration support to be pro...

Scarce resources such as material, labor, and equipment are to be optimized to improve the performance and lower production costs in flexible assembly lines. These resources are usually allocated optimally through the generation of schedules. In this paper, variants of a differential evolution-based algorithm are employed to schedule flexible assembly lines (FAL). The performance of the assembl...

Blood flow in six human melanoma xenograft lines grown s.c. in BALB/ c-nu/nu mice was studied and analyzed in relation to tumor growth characteristics. Two different methods were used to measure blood flow, i.e., uptake of HI'RI> and clearance of >33Xe. The percentage of the injected SI'KI>taken up per g of tumor tissue and the '"\o clearance rate were used as parameters for blood flow. The res...

Blood flow in six human melanoma xenograft lines grown s.c. in BALB/c-nu/nu mice was studied and analyzed in relation to tumor growth characteristics. Two different methods were used to measure blood flow, i.e., uptake of 86Rb and clearance of 133Xe. The percentage of the injected 86Rb taken up per g of tumor tissue and the 133Xe clearance rate were used as parameters for blood flow. The result...

The present study was designed to investigate the in-vitro morphological assessment of apoptotic effect caused by nimbolide on the selected cancer cell lines (DU-145, PC-3, A-549) and normal cell lines (NIH3T3, CCD-18Co). The cells were grown in 6 well tissue culture plates after treatment with different concentrations of nimbolide and untreated control cells. Apoptotic and necrotic ce...
