A software product line primarily structures the software architecture around the commonalities of a set of products within a specific organization. Commonalities can be implemented in prefabricated components, and product differences are typically treated by well-defined variation points that are actualized later on. Dynamic, domain-specific aspects, such as ad hoc customization by domian expe...

In the context of the semantic web; product knowledge is represented as product ontologies in it’s conceptual level. Product ontology construction, integration, and evolution greatly depend on the availability of well-defined semantics and powerful reasoning tools, as to facilitate machine understandability of web resources. In order to capture the semantic of a complicated product data model, ...

In this paper, the effect of Polypropylene Fibers added to concrete on strength and thermal resistance of high strength concrete has been investigated. Therefore, five tests have been carried out to reach this goal which it includes; effect of weight percent of polypropylene fibers on mechanical properties of concrete, effect of fiber’s length on the strength of high strength concrete, effect o...

A case study is used in order to analyse information technology's function in managing the complex network of resources that interact behind a specific product and that contribute to a final product ready for use (see, for instance Wedin, 2001). This "product-centred resource network" is analysed by means of a resource categorisation introduced by Håkansson & Waluszewski (forthcoming). Informat...

Hybrid fiber reinforced concrete (HFRC) consisting of two or more different types of fibers has been widely investigated because of its superior mechanical properties. In the present study, the effect of the addition of steel (0.25%, 0.5%, 0.75%, and 1% of concrete volume) and Polypropylene (0.2%, 0.4%, and 0.6% of concrete volume) fibers on the surface scaling resistance of concrete, depth of ...

Characteristics of produced concrete become changedthrough changingthe characteristics of materials constituting the concrete. These changes include: The quality of cement, the real ration of water to cement: with neglecting the further water within the aggregates or lack of that, the consideredratio fluctuates and the characteristics of the aggregate which are related to the following dimensio...

Nowadays, concrete with strength higher than 50 MPa is utilized due to the ever increasing need for higher strength and prolonged healing properties. Despite the widespread use of high-strength concrete, only a few research projects have been conducted on the punching shear strength of high-strength concrete slabs. Reinforced concrete flat slabs are widely employed in structural systems. The lo...

Nanotechnology will serve as a suitable solution to achieve high performance in future construction and construction. Using this new technology, creativity and innovation can be achieved in the building industry. one of these new technologies of smart concrete is that in recent years, many researches and experiments have been done in scientific research centers around the world, so that the con...

this paper is based on an experimental research that examined the effects of concrete`s major parameters on durability of concrete pavements and curbs under freezing and thawing cycles. these parameters include concrete mix design parameters such as water-cement ratio, fine aggregate percentage and using air entraining admixture and simulating real freeze-thaw cycles that infrastructures underg...
