This study presented an improved algorithm for solving large scale LAP. A preprocessing (PP) algorithm was proposed...

The knowledge of how to exactly deploy a wireless multi-hop network can be of interest for both researchers and engineers. Engineers may be interested in the possibility of extending the coverage area of their traditional access point and to provide ubiquitous Internet connectivity at a significantly reduced cost and some communities have already started to do so [1]–[3]. Researchers need large...

This paper describes the results obtained from the merging of two techniques that provide improvements to search and retrieval using Latent Semantic Indexing (LSI): Essential Dimensions of LSI (EDLSI) and partial singular value decomposition (PSVD) updating. EDLSI utilizes an implementation of LSI that requires the use of only a few dimensions in the LSI space. The PSVD updating and folding-up ...

This paper addresses the problem of calibrating a pinhole camera from images of a surface of revolution. Camera calibration is the process of determining the intrinsic or internal parameters (i.e. aspect ratio, focal length and principal point) of a camera, and is important for both motion estimation and metric reconstruction of 3D models. In this paper, a novel and simple calibration technique...

In the near future, there is potential for a tremendous expansion in the number of Earth-orbiting CubeSats, due to reduced cost associated with platform standardization, availability of standardized parts for CubeSats, and reduced launching costs due to improved packaging methods and lower cost launchers. However, software algorithms capable of efficiently coordinating CubeSats have not kept up...

We report on some recent work of the authors showing the relations between singular (point) perturbation of the Laplacian and the dynamical system describing a charged point particle interacting with the self–generated radiation field (the Maxwell–Lorentz system) in the dipole approximation. We show that in the limit of a point particle, the dynamics of the system is described by an abstract wa...

The benefits that can be derived from reusing software include accelerated development, reduced cost, reduced risk and effective use of specialists. Reuse of software artifacts during the initial stages of software development increases reuse benefits, because it allows subsequent reuse of later stage artifacts derived from earlier artifacts. UML is the de facto modeling language used by softwa...

In the past, research in traffic assignment modeling has been directed primarily towards the deterministic model. Alternative, more behavioral principles were thought to be too demanding computationally. This paper presents two mathematical contributions that enable one to solve a logit assignment model with flow-dependent travel times at a reduced cost. First, a convergence test for Fisk's min...

The dynamics of a particle which is linearly coupled to the environment of a Boson field is investigated. For velocity coupling and for local (position) coupling the reduced dynamics of the particle induces superselection rules for the momentum, if the Boson field is infrared divergent. Thereby the Hamiltonian of the total system remains bounded from below.

This study demarcates cost-inefficiency in Chinese banks into X-inefficiency and rent-seeking-inefficiency. A protected banking market not only encourages weak management and X-inefficiency but also public ownership and state directed lending encourages moral hazard and bureaucratic rent seeking. This paper uses bootstrap non-parametric techniques to estimate measures of X-inefficiency and rent...
