We consider the Robin Hood model of dry friction to study entropy transfer during sliding. For the polished surface (steady state) we study the probability distribution of slips and find an exponential behavior for all the physically relevant asperity interaction-distance thresholds. In addition, we characterize the time evolution of the sample by its spatial fractal dimension and by its entrop...

We derive new fixed-point theorems for subrecursive classes, together with a theorem on the uniformity of certain reductions, from a general formulation of the technique of delayed diagonalization. This formulation extends the main theorem of U. Schiining (Theoret. Compuf. Sci. 18 (1982). 955103) to cases which involve infinitely many diagonal classes Y$, and which allow each M, to contain unco...

A general simulation model of market competition is developed to explore the effectiveness of and interactions between different types product exploration and exploitation strategies i.e. innovation, imitation and process improvement. The model, like real markets, is highly nonlinear such that analytical solutions in the form of optimal marketing strategies are not possible. Hence, we use simul...

Our educational systems focus on honing children’s cognitive skills from the moment they enter the kindergarten classroom. But very little emphasis is placed on educating children in the management of the inner conflicts and unbalanced emotions they bring with them every day to school. As new research sheds light on the development of the brain and concepts such as “emotional intelligence” beco...

This paper reports on the development and validation of a survey instrument for measuring the culture of Quality Management (QM) in K-12 educational settings. The intent was to develop an instrument that would tap both the behavioral norms and the underlying values and beliefs associated with a Quality culture. The process used in the development and honing of this measurement instrument includ...

The internship program is an important in educational institutions, especially Vocational High Schools (SMK) Indonesia. purpose of this study was to evaluate the success rate Program honing students' skills and preparing students for world work. This research evaluation approach with CIPP model or context, input, process, product. conducted on 100 SMK who had completed during Covid-19 pandemic....

This paper discusses the experimental investigation to find out the optimal electrolyte composition in improving the surface quality of the gear teeth profile during surfacing finishing of bevel gears by the electrochemical honing process. In this study, AISI 1040 was used as the workpiece material, mixtures of sodium chloride and sodium nitrate in different ratios were used as the input parame...

Honing and Ladinig (2008) make the assertion that while the internal validity of web-based studies may be reduced, this is offset by an increase in external validity possible when experimenters can sample a wider range of participants and experimental settings. In this paper, the issue of internal validity is more closely examined, and it is agued that there is no necessary reason why internal ...

OBJECTIVE The transition from childhood to adulthood is characterized by improved motor and cognitive performance in many domains. Developmental studies focus on average performance in single domains but ignore consistency of performance across domains. Within-individual variability (WIV) provides an index of that evenness and is a potential marker of development. METHOD We gave a computerize...
