Traditionally, urban analysis has been quick to adopt and benefit from developments in technology (e.g., microcomputer, GIS) and techniques (e.g., statistics, mathematical programming). This has not been the case, however, with newer methods of spatial analysis – in particular, spatial statistics. Only recently has this situation started to change. This paper documents the confluence of spatial...

precipitation plays an important role in the global energy and water cycle. special interest in long-term precipitation analyses arises from the need to assess climate change and its impacts on all spatial scales. based on this demand national and international organization initiated and support many research and monitoring programs. there are a lot of centers developing gridded precipitation d...

Parameter estimation of the spatial auto-regression model (SAR) is important because we can model the spatial dependency, i.e., spatial autocorrelation present in the geo-spatial data. SAR is a popular data mining technique used in many geo-spatial application domains such as regional economics, ecology, environmental management, public safety, public health, transportation, and business. Howev...

nowadays, undoubted access to up to date with high spatial resolution and low temporal resolution of meteorological parameters is a one of the necessary needs for meteorological science researches. in order to doing this research have been used the different daily, monthly and yearly iran precipitation from global and regional data base of gpcpøŒ gpccøŒ aphrodit v101 0.25øŒ aphrodit v101 0.5 ùˆ...

Examination of the effects of fishing on marine ecosystems requires historical catch data on appropriate spatial scales. Most commercial fishing data are only currently available in the form of landings data that do not delineate the marine area from which the catch was extracted. Even when statistics are available by defined spatial areas such as the statistical areas used by the Food and Agri...

Because of the explosively increasing information of image and video in various storage devices and Internet, the image and video compression technique becomes more and more important. This paper introduces the basic concept of data compression which is applied to modern image and video compression techniques such as JPEG, MPEG, MPEG-4 and so on. The basic idea of data compression is to reduce ...

Motorization and increased levels of car ownership have partly contributed to traffic congestion and air pollution, which is a prime concern in the era of climate change. Therefore, vehicle ownership-related topics have been extensively explored by transportation scholars, economists, and planning researchers. However, relatively fewer scientists have investigated the spatial patterns and socio...

We analytically demonstrate the existence of white light solitons in logarithmically saturable noninstantaneous nonlinear media. This incoherent soliton has elliptic Gaussian intensity profile, and elliptic Gaussian spatial correlation statistics. The existence curve of the soliton connects the strength of the nonlinearity, the spatial correlation distance as a function of frequency, and the ch...
