Based on the stimulus–organism–response (SOR) model, purpose of current study is to investigate two types privacy concerns, i.e., concern abuse (PCA) and finding (PCF), in relation online collaborative learning (OCL). Further, another aim knowledge-sharing perceptions (KSP) as a mechanism between PCA PCF with OCL. A survey was used collect data from postgraduate university students Pakistan. Th...

The Railway Technical Research Institute (RTRI) has developed a new pantograph test facility, the “High-Speed Test Facility for Pantograph/OCL Systems,” to develop pantographs high-speed trains, wear resistant contact strips, and so on. This facility mainly consists of four parts: rotational disk with attached wire which can rotate at high speed up 500 km/h, exciters reproduce lateral arrangeme...

Peroxidation of low-density lipoprotein (LDL) lipid is generally thought to represent the initial step in a series of modification reactions that ultimately transform the protein moiety of the lipoprotein into a form recognized by receptors different from those that bind native LDL. Uptake of LDL via these alternative receptors can lead to the formation of lipid-laden cells, which are typical f...

UML is the de facto standard language for analysis and design in object-oriented frameworks. Information systems, and in particular information systems based on databases and their applications, rely heavily on sound principles of analysis and design. Many present-day database applications employ object-oriented principles in the phases of analysis and design due to the advantages of expressive...

The role of UML models in software development has changed considerably over the last years. While UML was used in its early days mostly as a notation for sketching ideas, developers more and more recognize now the value of a UML model as a formal document that can be processed by tools, e.g. in order to generate code and documentation. Precise software models, however, can usually not be expre...

In recent years, MDA techniques have been strongly developed. Thus, translation techniques such as UML to some program languages have gained a lot of attention. Translation techniques such as OCL to JML have been also researched. OCL is a language to describe detail properties of UML and standardized by OMG, while, JML is a language to specify properties of Java program. Both OCL and JML are ba...
