This paper presents some enhancements in the temporal reasoning of a Hierarchical Task Network (HTN) planner, named SIADEX, that, up to authors knowledge, no other HTN planner has. These new features include a sound partial order metric structure, deadlines, temporal landmarking or synchronization capabilities built on top of a Simple Temporal Network [3].

This article examines the relationships among task goal clarity, task significance, and individual-level task performance. While both goals and task significance are important in extant public-management research, a theoretical integration of the variables is needed. This study makes the theoretical contribution of explaining how these variables might work together in a public organization. In ...

It is well recognised that task analysis and modelling are complementary to object oriented software development. While the latter has gained widespread use, the adoption of the former is still rare in industry. We argue that while good methodologies are important, they are not sufficient by themselves to ensure their rapid adoption. What is also needed are tools which will mediate the implemen...

In this paper we evaluate the Parallel-Horus parallelization strategy, and propose some approaches for further optimization. Also, we compare the Parallel-Horus approach with other strategies described in the literature. Furthermore, we investigate if adding automatic task parallelization is possible, and if this can be done in a user-transparent way.

objectives: the aim of this study was to identify the role of attentional process in postural control using choice reaction time task while changing the visual and proprioceptive cues under difficult balance task (standing on one-leg). methods: this cross-sectional study was conducted by participating 20 young people (22.75±2.29). each subject performed one-leg standing as balance task for each...

according to a basic prediction made by the revised hierarchical model (rhm,kroll & stewart, 1994), there is no l2 conceptual connection at the beginning stages of language learning as l2 learners mostly rely on l1 conceptual connections to retrieve the meaning of the l2 words.with increasing proficiency, however, there would be a direct access from l2 to the conceptual system. available litera...

A B S T R AC T Learning and understanding are often differentiated and distinguished from each other in people's experience and thinking, but they are necessarily related to each other. This relationship is visible in examples of how individuals express what they mean by learning. Starting from an observed similarity of expression, an idea is presented about how understanding may be appropriate...

As computers have become more powerful, the simulations and data processing applications that use them have become resource hungry, and, at the same time more complex. The complexity of simulations has increased in terms of the number of dimensions (from 1D to 2D to 3D), the set of equations being simulated (from one equation, to multiple equations in one domain, to multiple equations in multip...

The purpose of this qualitative exploratory study was to identify factors that influenced prospective and experienced secondary level science teachers’ reasoning as they evaluated or selected tasks to formatively assess their students’ understanding of scientific concepts. The analysis of the coded written responses revealed two categories of factors that influenced the teachers’ reasoning: (1)...
