This paper describes the hardware and software architecture of the Attempto RoboCup-99 team. The different parts of robot, sensor and computer hardware which are used are presented. Then the robot control architecture which realizes a hybrid control, consisting of a reactive behavior based component and a planner component for more complex tasks is introduced. Also the problems we currently are...

The static synchronous compensator (STATCOM) is one type of FACTS devices which resembles in many respects a rotating synchronous condenser used for voltage control and reactive power compensation. The STATCOM can increase transmission capacity, damping low frequency oscillation, and improving voltage stability. This paper presents a control block diagram of STATCOM for the voltage stability im...

Bridging the gap between the specification of software requirements and actual execution of the behavior of the specified system has been the target of much research in recent years. We have created a natural language interface, which, for a useful class of systems, yields the automatic production of executable code from structured requirements. In this paper we describe how our method uses sta...

Distributed, reactive software systems, e.g. process control tools, can be modelled with the Unified Modelling Language (UML). Recently such UML models are used to generate source code automatically. Because of the complexity of UML, it is necessary to restrict the usage of its constructs by defining UML profiles to allow the automatic generation of source code. In this paper a UML profile for ...

The aim of the panel session is to clarify issues involved in software evolution, but more particularly, to identify and explore promising solutions and research directions, in order to identify strategic goals for the research community and solution visions for practitioners. By evolution, we mean a stage of software lifecycle where the software undergoes substantial changes and this also incl...

This paper focuses on improving the active and reactive power control of Wind Energy Conversion System (WECS) by employing the Battery Energy Storage System (BESS) and controlling the frequency and voltage regulation instantaneously. The proposed power control scheme is composed of two control loops so that they are implemented and designed for active power control and controlling the reactive ...

Multi-objective (energy–economic–safety) assessment of ethyl acetate production involving a heat pump is presented in this paper. The designed to intensify separation and reduce the total operating cost. Two pathways are upgraded using pump, conventional process reactive distillation column with unit. Detailed models including environment have been compiled optimized Aspen Plus software. Both b...

PLA is one of the most promising bio-compostable and bio-degradable thermoplastic polymers made from renewable sources. PLA is generally produced by ring opening polymerization (ROP) of lactide using the metallic/bimetallic catalyst (Sn, Zn, and Al) or other organic catalysts in a suitable solvent. In this work, reactive extrusion experiments using stannous octoate Sn(Oct)2 and tri-phenyl phosp...
