"ÞAbstract Mathematical methods have been used to study location problems for two centuries, however, the mathematical theories have not been well established. Recently the author, together with Dr. McAsey and others, first formulated the mathematical models for quite general location problems. Furthermore, we proved the existence of optimal locations, and derived a system of equations whose so...

A complete investigation on the free vibration and stability analysis of beams made of functionally graded materials (FGMs) containing open edge cracks utilizing four beam theories, Euler-Bernoulli, Rayleigh, shear and Timoshenko, is performed in this research. It is assumed that the material properties vary along the beam thickness exponentially and the cracked beam is modeled as two segments ...

This paper presents background theories and required steps towards preparation of a WLAN location system. This paper targets on a software project and intention behind this paper is to motivate the young researchers in the area. Keywords-component; WLAN; Location Systems; K-nearest

The paper starts with a summary of the way the new theories of international trade have incorporated the role of multinational companies (MNCs) in the location of production. The main, specific assumptions used to incorporate MNCs’ activities relate to joint inputs at the company’s level combined with assumptions regarding costs at the plant level and spatial transaction costs. It is claimed th...

Locational reasoning plays an important role in many applications of AI problem-solving systems, yet has remained a relatively unexplored area of research. This paper addresses both theoretical and practical issues relevant to reasoning about locations. We de ne several theories of location designed for use in various settings, along with a sound and complete belief revision calculus for each t...

With advances in Location-Based Services(LBSs), the motivation for indoor LBSs is becoming stronger since the complexity of indoor spaces. Semantic location model is becoming a pervasive data model to face with this challenge. The hybrid semantic methods and theories are used into this model to define and manage semantic information and location information. In this paper, we analyze some seman...

Two theoretical frameworks have been widely used to understand the response of monsoons to local and remote forcings: the vertically integrated atmospheric energy budget and convective quasi-equilibrium (CQE). Existing forms of these frameworks neglect some of the complexities of monsoons, such as the shallow meridional circulations that advect dry air from adjacent deserts into the middle and ...
