formal framework allows us to prove that our solutions are correct. The presented solutions are handled in a uniform manner and apply to all of the models of the family. Index Terms—Spatial databases and GIS, cone-based directional relations, inverse and composition operators. Ç

expression of power relationships. Outside the direct sphere of the state, the exercise of power within production organizations or in apparatuses of experience (such as the family) ultimately relied on the ability of these apparatuses to call upon the state (or para-states, such as the Church) to enforce

theories regarding the motivational effects of charismatic leaders, it received only limited support in a recent empirical test The present investigation was designed to extend the self-concept-based theory by linking some elements of the theory with the self-concordance model, a motivational theory

model: customers arrive as a Poisson stream of rate n, ! 1, at a collection of n servers. Each customer chooses some constant d servers independently and uniformly at random from the n servers, and waits for service at the one with the fewest customers. Customers are served according to the first

spacetime, unlike previous solutions for cosmological black holes, which violate the energy conditions in some region of spacetime. In addition, it is demonstrated that radiation-dominated and matter-dominated Einstein-de Sitter universes can be directly matched across a hypersurface of constant time

The recent discovery of dark energy has prompted an investigation of ways in which the accelerated expansion of the universe can be realized. In this dissertation, we present two separate projects related to dark energy. The first project analyzes a class of braneworld models in which multiple
