Land use/land cover (LU/LC) changes were determined in an urban area, Tirupati, from 1976 to 2003 by using Geographical Information Systems (GISs) and remote sensing technology. These studies were employed by using the Survey of India topographic map 57 O/6 and the remote sensing data of LISS III and PAN of IRS ID of 2003. The study area was classified into eight categories on the basis of fiel...

BACKGROUND Over the past two decades, geographical accessibility of urban resources for population living in residential areas has received an increased focus in urban health studies. Operationalising and computing geographical accessibility measures depend on a set of four parameters, namely definition of residential areas, a method of aggregation, a measure of accessibility, and a type of dis...

In this thesis we study two research aspects of geographical routing: efficient geographical addressing and a new routing scheme. In the first part we offer a novel geographical routing algorithm that relies on a well known data structure called Quadtree. Quadtree is an efficient method of mapping a twodimensional area by recursively partitioning it to disjoint squares. We present a greedy, gua...

BACKGROUND Neural tube defect (NTD) prevalence in northern China is among the highest worldwide. Dealing with the NTD situation is ranked as the number one task in China's scientific development plan in population and health field for the next decade. Physical and social environments account for much of the disease's occurrence. The environmental determinants and their effects on NTD vary acros...

STUDY OBJECTIVE As earlier studies have shown space-time clusters at onset of type 1 diabetes in the south east region of Sweden we investigated if there also has been any geographical clusters of diabetes in this region. DESIGN The place of residence (coordinates) at the time of diagnosis were geocoded in a geographical information system (GIS). All children diagnosed with type 1 diabetes up...

In medical education and clinical care, representations of the patient help health care teams in planning and coordinating patient care, sometimes over geographic distances. This takes forms ranging from telemedicine consultations to using simulations and information and communication technology representations to plan, and at times, perform clinical procedures such as are done in intensive car...

This paper uses the establishment of federal agricultural experiment stations to provide new evidence on the effects of university research on long-term regional development. Our analysis of county-level agricultural census data from 1870 to 2000 reveals that station establishment increased local crop revenue per acre for 30-40 years, but localization effects do not persist to the present day. ...

This paper proposes optimal prediction intervals for the future generalized order statistic (GOS) based on the first GOS (ordinary order statistics, usual record values, -record values) from an exponential population. A conditional argument is considered for obtaining an optimal prediction interval for future GOS. A numerical example illustrates this technique.

Agile software development represents a major approach that has gained increasing popularity in recent years. Economy forces agile organizations to overcome geographical distances to benefit from accessing a larger resource pool and to reduce development costs. However, agile and distributed development approaches differ significantly in their key tenets. While agile methods mainly rely on info...

The idea of the creative individualist spawning innovations as a solitude effort is no longer realistic. Huge innovation projects, relying on project teams, have to be permanently conducted by organizations to assure their competitiveness. These projects often take place in distributed teams, making use of groupware to bridge temporal and geographical distances. Research in social psychology on...
