main purpose of the present research is to invent some tools for confirming hypotheses in analytic-reasoning researches. for this regard, the analytic research is used. the present tools, weighting to reasons tool (wrt) and repeat reasoning tool (rrt) are used for evaluating hypotheses of the current research. the results of the wrt shows that reasons weight (rw) for the first hypothesis is 8 a...

background it is obvious that most of informal learnings of social skills and constructive plays occur in school yards and play-fields where children spend much of their non-official time of teaching. this study aimed to investigate the impact of schools' open space on learning and educational achievement of elementary students in ahvaz, southwest of iran. materials and methods at a cross-...

The burgeoning " information overload " problem plaguing today's technology users is well-documented. On nearly every front, the amount of data collected electronically far outstrips our ability to keep pace with understanding it. We have embedded devices with sensors that continually gather data; online digital libraries that regularly add new material as well as old; supermarket chains that c...

to AI. An automated tool can do boring and repetitive reasoning, freeing experts to do more difficult and creative work. Indirectly, it can make explicit the knowledge and reasoning used by experts in the field. Finally, an automated tool can consider all possibilities, sometimes exploring scenarios that human experts may miss. This article discusses automating reasoning for dating geological l...

National Science Foundation under awards OCI-0968277 and OCI-0943761 Knowledge of how a science data product has been generated is a critical component to determining its fitness-for-use for a given analysis. One objective of science information systems is to allow users to search for data products based on a wide range of criteria; spatial and temporal extent, observed parameter, research doma...

Recent legal cases have shown that digital evidence is becoming more widely used in court proceedings (by defense, accusation, public prosecutor, etc.). Digital tracks can be left on computers, phones, digital cameras as well as third party servers belonging to Internet Service Providers (ISPs), telephone providers and companies that provide services via Internet such as YouTube, Facebook, Gmai...

The Virtual Solar-Terrestrial Observatory (VSTO) is a distributed, scalable education and research environment for searching, integrating, and analyzing observational, experimental and model databases in fields of solar, solar-terrestrial and space physics. Our work on VSTO required us to create a formal, machine understandable representation for concepts, relations and attributes of physical q...

Space-time convolutional codes have shown considerable promise for providing improved performance for wireless communication through combined diversity and coding gain. However, systematic design procedures for space-time convolutional codes have not yet been developed. To date, the few existing example space-time codes have been developed using hand design. Systematic design procedures are pre...

We discuss the design and implementation of CAD tools for creating decorative solids that tile 3-space in a regular, isohedral manner. Starting with the simplest case of extruded 2D tilings, we describe geometric algorithms used for maintaining boundary representations of 3D tiles, including a Java implementation of an interactive constrained Delaunay triangulation library and a mesh-cutting al...
