More than 90% of Malaysian roads are constructed using asphaltic concrete. However, previous investigations of asphaltic concrete have mainly concentrated on the macroscopic properties of the composite materials based on the assumption that the mixtures are homogeneous and isotropic. This paper applies a digital image processing technique to compare the orientations of coarse aggregate particle...

Due to the many limitation and poor data handling in the existing relational database, the software professional and researchers moves towards the object-oriented database which has much better capability to handling the real and complex real world data i.e. clear and crisp data and also have the capability to perform some huge and complex queries in an effective manner. On the other hand, a ne...

This paper discusses strategies and concepts of information and communication-support for knowledge-intensive work processes. The necessity of social informatics or organizational informatics according to Rob Kling results from the complementarity of formal (syntactic), product oriented and informal (semantic), process oriented, technical, and social view in informatics. The understanding of ma...

Recursive queries are required for many tasks of database applications. Among them we can mention Bill-Of-Material (BOM), various kinds of networks (transportation, telecommunication, etc.), processing semistructured data (XML, RDF), and so on. The support for recursive queries in current query languages is limited. In particular, this concerns corresponding extensions of SQL in Oracle and DB2 ...

We conducted 3 studies to explore cultural differences in global versus local processing and their developmental trajectories. In Study 1 (N = 363), we found that Japanese college students were less globally oriented in their processing than American or Argentine participants. We replicated this effect in Study 2 (N = 1,843) using a nationally representative sample of Japanese and American adul...

Cloud computing is an evolving and fast-growing computing paradigm that has gained great interest from both industry and academia. Consequently, universities are actively integrating cloud computing into their IT curricula. One major challenge facing cloud computing instructors is the lack of a teaching tool to experiment with. This paper introduces TeachCloud, a modeling and simulation environ...

Many embedded systems, such as systems in the process control and measurement domains, are designed to perform continuous processing of input values and to produce and maintain corresponding output values. At the same time these systems have to react on events that reconfigures the processing algorithms. This paper will present some of the results of a Danish research project entitled “Architec...

So far, parallelism in complex-object and object-oriented DBMS has not been investigated in depth because descriptive and set-oriented query languages did not exist for these systems. However, with standardization of OQL by ODMG or SQL3 by ANSI, systems implementing these languages are ready to exploit parallel query processing strategies. In this paper, we explain differences between parallel ...

A key observation is that the invariants in database management determine the mapping steps of the supporting architecture. Referring to the multi-layered architecture of record-oriented database management systems (DBMSs), we sketch the advances made during the past decades. Then, we explore the ways how this proven architecture can be used to implement XML DBMSs (XDBMSs). Major changes and ad...
