This empirical research was undertaken as part of a multi method programme of research to investigate unsupported claims made of object oriented technology A series of subject based laboratory experiments including an internal replication tested the e ect of inheritance depth on the maintainability of object oriented software Subjects were timed performing identical maintenance tasks on object ...

Satellite observation scheduling plays a significant role in improving the efficiency of satellite observation systems. Although many scheduling algorithms have been proposed, emergency tasks, characterized as importance and urgency (e.g., observation tasks orienting to the earthquake area and military conflict area), have not been taken into account yet. Therefore, it is crucial to investigate...

This study set out to explore whether different input enhancement tasks as implicit instruction techniques had any significant impact on the intake of causative verbs in English as a foreign language among Iranian EFL learners. For this purpose, three intact classes consisting of 75 male and female intermediate L2 learners were randomly divided into three conditions: simultaneous grammar consci...

The present study investigated the effects of cognitive complexity of pedagogical tasks on the learners’ uptake of salient features in the input. For the purpose of data collection, three versions of a decision-making task (simple, mid, and complex) were employed. Three intact classes (each 20 language learners) were randomly assigned to three groups.  Each group transacted a version of a decis...

The eyes-free touchscreen interface is a category of interfaces for controlling devices with minimal visual attention. We apply design framework the generation imaginary layouts and propose series input menu selection, arrow control, data entry. These are oriented around U-shaped diagonal optimized one-handed thumb interaction. experiment tests participants’ cognitive performance toward specifi...

In this work we propose an innovative approach to data mining problem. We propose very flexible data mining system based on serviceoriented architecture. Developing applications according to SOA paradigm emerges from the rapid development of the new technology direct known as sustainability science. Each of data mining functionalities is delivered by the execution of the proper Web service. The...

This paper presents a formalization of the Web Service composition problem as a search problem in an AND/OR graph, and a search algorithm for searching the graph to identify composite service(s) that satisfies a Web Service request. Given a service request that only can be satisfied by a composition of Web Services, we identify the service categories that are relevant to the request and dynamic...

Military boxing, a kind of Chinese martial arts, is widespread and health beneficial. In this paper, the authors introduce a military boxing learning system realized by 3D motion capture, Web3D and 3D interactive technologies. The interactions with the system are natural and intuitive. Users can observe and learn the details of each action of the military boxing under different views and scales...

We consider the synthesis of reactive systems from specifications with identifiers. Identifiers are useful to parametrize the input and output of a reactive system, for example, to state which client requests a grant from an arbiter, or the type of object that a robot is expected to fetch. Traditional reactive synthesis algorithms only handle a constant bounded range of such identifiers. Howeve...
