This study focuses on learning in three different hypermedia environments that either support autonomous learning, learner-controlled learning or system-controlled learning and explores the mediating role of academic self-regulation style ( ASRS; i.e., a macro level of motivation) on learning. This to gain more insight in the conditions under which learning in hypermedia environments is effecti...

Real-time coal flow monitoring is crucial for efficient mine transportation. Traditional vision acquisition devices generate two-dimensional images that are not accurately identified in the complex underground environment, such as dust, water mist, and low light. In this paper, we propose a conveyor belt detection method integrates laser scanning binocular to address problem. Our proposed has s...

This study aimed to derive psychometric characteristics ‎of a Jordanian version of the Autism Spectrum Rating ‎Scale (ASRS) for ages 6–18..To achieve aim ‎study, autism spectrum ‎disorder scale was prepared and applied random ‎sample consisting 370 individuals diagnosed with ‎autism disorder, in age group 6–18 years. ‎The findings showed that diagnostic treatment ‎scale items on ‎spectrum disor...

In this position paper we describe an interface to incorporate application-specific knowledge for conflict resolution in an optimistically replicated file system. Conflicts arise in such systems because replicas of an object can be modified simultaneously in different network partitions. Application-specific knowledge is made available by the application writer in specialized tools called Appli...

On 18 January 2005, two small, instrumented rockets were launched from Andøya Rocket Range (69.3◦ N, 16◦ E) during conditions with Polar Mesosphere Winter Echoes (PMWE). Each of the rockets was equipped with a Positive Ion Probe (PIP) and a Faraday rotation/differential absorption experiment, and was launched as part of a salvo of meteorological rockets measuring temperature and wind using fall...

To better understand the nature of impairment resulting from attention-deficit/hyperactivity disorder (ADHD) for students in a post-secondary education (PSE) setting, the authors analyzed the symptoms and associated impairment of 135 students with a diagnosis of ADHD who were recruited via Student Disability Services in Canadian post-secondary institutions. The authors (a) developed a novel sem...

in common classical methods of cavity depth estimation through microgravity data, usually when a pre-geometrical model is considered for the cavity shape, the simple geometrical models of sphere, vertical cylinder and horizontal cylinder are commonly used. it is obviously an important fact that in real conditions the shapes of the cavities are not exactly sphere, horizontal cylinder or vertical...

In this paper, a technique for realizing a floating capacitance multiplier based on the use of dual output current conveyors and grounded capacitance is proposed. Its multiplication factor can be tuned by changing the ratio of resistors. Moreover, the circuit is easily modified to electronically tunable floating capacitance multiplier by using current controlled conveyor. Simulation results are...

There may be advantages to be gained by combining Case-Based Reasoning (CBR) techniques with numerical models. In this paper we consider how CBR can be used as a flexible query engine to improve the usability of numerical models. Particularly they can help to solve inverse and mixed problems, and to solve constraint problems. We discuss this idea with reference to the illustrative example of a ...

Sex allocation theory predicts that facultative maternal investment in the rare sex should be favoured by natural selection when breeders experience predictable variation in adult sex ratios (ASRs). We found significant spatial and predictable interannual changes in local ASRs within a natural population of the common lizard where the mean ASR is female-biased, thus validating the key assumptio...
