Intra-Censal Geographical Information Systems: Application to Binational Border Cities

This paper presents a new design for a census-based binational geographic information system. GIS has had limited application intra-censally i.e. between nations. The reasons are the formidable obstacles of standardization of attributes, matching of meaning of attributes, consistency of data-bases, and consistency of boundary files. Many problems in public administration can be solved by using ...

Geographical Domain and Geographical Information Systems

In the eld of geography, we have beenexamining the contribution of the morpho-genetic rep-resentation to the comprehension of the cycle: reality,representation, model, reality. A distinction is madebetween map and geomap based on the notion of locus-object. 1. Foundations and limits of cartographic rep-

investigation of single-user and multi-user detection methods in mc-cdma systems and comparison of their performances

در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...

Evolution of Geographical Information Systems

SUMMARY Geoinformatics is described as a scientific and technical complex integrating the branch of scientific knowledge, the appropriate technology and the applied, or productive, activities concerned with the development and implementation of geographical information systems. Four stages of geoinformatics evolution are discussed, and its prospects are outlined in brief. 1. Introduction Geoinf...
