Standardized and objective design criteria for evaluating web-based learning platforms can effectively distinguish the quality of a platform and, therefore, contribute in improving web-based learning outcomes. This is a two-phase study, in which Delphi technique and heuristic evaluation were employed in the first phase to develop the evaluation criteria and scale of web-based learning platforms...

Web services need to be orchestrated to achieve complex demand. However, existing approaches on Web service composition are mainly based on syntax match. It is very difficult to compose heterogeneous Web services with syntax in accord with function. Gradually, Petri net becomes a powerful system modeling and analysis tools research discrete event dynamic system. In order to solve this problem, ...

Since the internet network's establishment, World Wide Web is considered as most important tool used by billions of people across world. It allows to share media, read, write, publish and interact with others via internet. its advent, has evolved from a read-only medium technological network collaborative one where learners are interlinked in various ways. Through stages evolution, English lang...

There exists a set of web-based tools for integration and exploring information linked to annotated genetic variants. We developed , an R-package for haploR querying such web-based genome annotation tools (currently implementing on HaploReg and RegulomeDB) and gathering information in a format suitable for downstream bioinformatic analyses. This will facilitate post-genome wide association stu...

Evolutionary conservation analyses are important for the identification of protein-protein interactions. For protein complex structures, sequence conservation has been applied to determine protein oligomerization states, to characterize native interfaces from non-specific crystal contacts, and to discriminate near-native structures from docking artifacts. However, a user-friendly web-based serv...

The purpose of this study is to measure learners’ perceptions toward the Web-based distance learning activities/assignments portion of a hybrid program. These activities and assignments were designed based on a set of appropriate instructional parameters and objectives. By measuring learners’ perceptions, this study attempts to find whether these activities/assignments promote learning. This st...

the internet is already the primary source of tourist destination information for travelers. according to world tourism organization, about 95% of web users use the internet to gather travel related information and about 93% indicate that they visited tourism web sites when planning for vacations. the number of people turning to the internet for vacation and travel planning has increased more t...

Majority of the computer or mobile phone enthusiasts make use of the web for searching activity. Web search engines are used for the searching; The results that the search engines get are provided to it by a software module known as the Web Crawler. The size of this web is increasing round-the-clock. The principal problem is to search this huge database for specific information. To state whethe...
