One of the primary scientific targets of current and future CMB polarization experiments is the search for a stochastic background of gravity waves in the early universe. As instrumental sensitivity improves, the limiting factor will eventually be B-mode power generated by gravitational lensing, which can be removed through use of so-called “delensing” algorithms. We forecast prospects for dele...
Using Maps for Virtual Collaboration: Implementing a Framework for Visually Enabled Geocollaboration
The purpose of this study is to test whether the use of graphic information interfaces such as maps and simulations can enhance the general public’s understanding of scientific data and risk analysis, improve communication and virtual collaboration, and lead to environmental decision making that is less positional and more consensual. The research will be located in upstate New York in the Adir...
نگاشت های گویای استثنایی آن دسته از نگاشت های گویا هستند که نقطه ی تناوبی از هر دوره ی تناوب دلخواه نداشته باشند. ثابت شده است اگر نگاشت گویای r از درجه ی d ، نقطه ی تناوبی از دوره ی تناوب اولیه ی n نداشته باشد آن گاه {(d,n) ? { (2,2), (2,3), (3,2), (4,2) نگاشت های گویای استثنایی تحت تزویج های همدیس دسته بندی و مشخص شده اند. به عنوان مثال هر نگاشت گویای درجه ی 2 که فاقد مداری از دوره ی تن...

ing particular places, people and events into generalized categories, laws and policies is fundamental to any form of ruling. It is in this very process of abstraction that the colonial state legislates racial, sexual, and class/caste ideologies‖. Extremely small scale maps such as colonial maps of the world were abstractions which unified what is various, glossing over landscape details, rende...
In scientific machine learning, regression networks have been recently applied to approximate solution maps (e.g., the potential-ground state map of Schrodinger equation). this paper, we aim...
The links of Cartography to Art and culture are as old as the field itself. The art of painting has always been present within maps, which, in turn have always been regarded as a combination of scientific and artistic skills. One of the most prominent examples of the harmonic duality of maps as scientific tools and objects of culture is witnessed in the Netherlands during the 17 century, when t...
in recent years, the topic of desertification has been discussed in different ways in scientific areas. this event occurred globally, regionally and nationally and many steps were taken to stop it. desertification is challenged universally and its destructive effects are unavoidable and its consequences do endanger the life of inhabitants. the identification of sensitive regions and prevention ...
geomorphologic landforms associated with tourism and development has been considered by many researchers in recent years. geomorphologic landforms which have values and capabilities, considered in context of tourism, known as geomorphosite and are studied in geomorphotourism approach. in this paper, we used landsat satellite imageries, geological and topographic maps, data obtained by field obs...
