Iterative constant modulus algorithms such as Godard and CMA have been used to blindly separate a superposition of co-channel constant modulus (CM) signals impinging on an antenna array. These algorithms have certain deficiencies in the context of convergence to local minima and the retrieval of all individual CM signals that are present in the channel. In this paper, we show that the underlyin...

Object-oriented techniques have accrued popularity as the preferred paradigm of modern programming. Despite this, relational database management systems, with their underlying relational model, remain the top choice for persistence and retrieval of large quantities of data. Persistence mechanisms of data have not experienced the paradigm shift that the mechanisms of manipulation of data have. T...

The characteristics of a Zinc/Air (Zn/Air) primary cell are discussed. In addition, current technologies and the corresponding electrical performance are introduced. The basic principles of operation of a Zn/Air primary cell are discussed, focusing on the anode, cathode, and electrolyte. Basic kinetic and transport expressions are developed for the two main components of the cell: the anode and...

The use of feedback-based systems in the music domain dates back to the 1960s. Their applications span from music composition and sound organization to audio synthesis and processing, as the interest in feedback resulted both from theoretical reflection on cybernetics and system theory, and from practical experimentation on analog circuits. The advent of computers has made possible the implemen...

File prefetching is an eeective technique for improving le access performance. In this paper, we present a le prefetching mechanism that is based on on-line analytic modeling of interesting system events and is transparent to higher levels. The mechanism, incorporated into a client's le cache manager, seeks to build semantic structures, called access trees, that capture the correlations between...

In this paper, we present a newly developed analytical thermodynamic theory and show that it offers a simple understanding of entrepreneurship. The approach we present in the paper is different from previous work on the subject in that we not only borrow the mathematical tools from, and the analogy to thermodynamic but treat economics in general and entrepreneurship in particular as a thermodyn...

Introduction: Wedge filters are used in radiotherapy to modify photon beam and improve dose uniformity in the target volume. Determination of wedge dose distribution is important to improve treatment planning accuracy. The utilization of treatment planning software to obtain dose distribution is not always available. In this work an analytical model has been developed to calcu...

Systems subjected to holonomic constraints follow quite complicated dynamics that could not be described easily with Hamiltonian or Lagrangian dynamics. The influence of holonomic constraints in equations of motions is taken into account by using Lagrange multipliers. Finding the value of the Lagrange multipliers allows to compute the forces induced by the constraints and therefore, to integrat...

The selection of multi-functional teams is a key issue in problem solving. Currently there are no papers in the literature that discuss analytical approaches to forming teams. Furthermore, no comprehensive model exists to prioritize team membership based on customer requirements or product characteristics. To deal with the underlying complexities of the team selection process, a methodology for...

Virtualization is a technique that partitions a physical computer server into two or more virtual subsystems (or guests), each of which behaves as if it were a separate physical system. Through virtualization, more efficient usage of resources can often be achieved. However, virtualization comes with cost. In particular, the virtualization manager and the individual operating systems installed ...
