Nowadays using of new energies in the form of dispersed resources in the worlds is wide spreading. In this article we will design a dispersed production source in the form of a solar/wind hybrid power plant in order to supply the energy of a residential unit according to a sample load pattern. The aim of aforementioned design is to reduce its costs in a period of 20 years. In order to optimi...

Nowadays, in highly competitive global markets and constant pressure to reduce total costs, enterprises consider group technology and Supply Chain Management (SCM) accordingly and usually separately as the key elements for intra and inter facilities improvement. Simultaneous consideration of the elements of these two disciplines in an integrated design can result in higher efficiency and ...

due to the massive loss of leaves in parks and green spaces and big cities such as isfahan and the lack of domestic production of leaf vacuum shredder machine for use in large green spaces of parks, the design and construction of the collecting and recycling by the system is need so the design of the vaccum section which is one of the main parts and includes entrance, channels and ducts and exh...

Pipe systems are often used to transfer moderate to medium water volumes between reservoirs or from well fields to consumers. Such systems consisting of an arbitrary number of reservoirs or other types of sources and sinks are considered here. The Lagrangean optimization principle is used for the determination of all pipe diameters giving minimum total cost of the system, when the individual di...

a fundamental shift to a total system approach for crop management in greenhouses is urgently needed to resolve escalating economic and environmental consequences of long-lasting undesired effects of synthetic pesticides used in combating agricultural pests. the aim of this study was to examine a potential new approach i.e. microbial-based production system (mps) for greenhouse-grown peppers. f...

2002 Software design inconsistency can be hard to trace manually. Computer assistance in detecting and resolving inconsistency issues can help improve the quality of sophisticated software designs. Existing solutions include design guidance, critiquing system and static consistency checking. Related research includes inconsistency management of requirements such as goal conflict resolution, vie...

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...
