in this thesis our aim is to construct vector field in r3 for which the corresponding one-dimensional maps have certain discontinuities. two kinds of vector fields are considered, the first the lorenz vector field, and the second originally introced here. the latter have chaotic behavior and motivate a class of one-parameter families of maps which have positive lyapunov exponents for an open in...
Original scientific paper In recent years information technology has grown very rapidly. In the context of GIS, Free/Open source concept and also three-dimensional implementation have had more development too. The usage of these types of software is increasingly growing because of reasons such as security, open standards, vendor independence. In this regard, one of the most significant problems...
Recent developments in the excavation and osteological studies of human skeletal remains have shown the need to adopt a computer and digital approach, which is both practical and methodological, and able to integrate the knowledge and skills acquired in recent years by different branches of archaeoantropological studies, using modern and innovative tools. JASs has repeatedly promoted a “renewal...
S trangely, the combination of geographic information systems (GIS) and visualization remains sufficiently unexplored to warrant a special issue of CC&A. Both fields can claim acceptance, a base of solid theory and practice, and delivery of technology as software products to practitioners. The fields seem to complement one another. yet they have developed in parallel, with little interchange or...
The Open Geospatial Consortium (OGC) [1] defines a number of standards, both for data models and for online services, that has been widely adopted in the Geographical Information System (GIS) community. This has lead to a number of software development efforts, online data archives, and application communities. The emergence of Web Service technique overcomes the shortcoming of traditional Dist...
the aim of this study is investigating the effect of teaching “metacognitive strategies” on the way which scientific information retrieval workes by the using of google scholar searching machine on the students of ms in the psycology & education faculty of allameh tabatabayi university in 2007-2008 academic year. the statistical community was the students of ms in psychology & education facult...
Species Distribution Models (SDMs) are correlative models that use environmental and/or geographical information to explain patterns of species occurrences. Those models are being used in various fields including climate change, invasive species research, evolutionary biology and epidemiology. Thanks to the availability of increasing computational resources, new methods continue to be developed...
the research questions were as follows: 1. is there any relationship between the students concious awareness of the form and implications of the conjuncations and their improvement in using appropriate conjunctions? 2. does students knowledge of the from and the implications of the conjunctions help them to produce more coherent writings. 3. does a comparison between english conjunctions and th...
The GIS software sector has developed rapidly over the last ten years. Open Source GIS applications are gaining relevant market shares in academia, business, and public administration. In this paper, we illustrate the history and features of a key Open Source GIS, the Geographical Resources Analysis Support System (GRASS). GRASS has been under development for more than 28 years, has strong ties...
it is not possible to understand developments of a country’s culture and civilization without knowing his believes and myths. whether it is north or south, east or west, planes or mountains, sahara or deserts, here in iran every corner includes valuable and precious treasures which are known all over the world, and cultural – historical objects which are found here adorn all well known museums...
