A wide variety of monitoring tests are available to help gauge HIV disease progression and the state of overall health. HIV viral load tests provide a picture of viral activity, while CD4 cell counts shed light on the status of the immune system and can help physicians predict—and therefore prevent—the development of opportunistic illnesses (OIs).These tests can help guide treatment decisions a...

The competitiveness of retail stores depends heavily on the ability to handle the challenges of reducing control costs and increasing customer service levels. One element that affects cost significantly is labour costs. This paper addresses proposing a procedure of finding the optimal solutions of personnel planning, especially by making use of the actual Point of Sales (POS) data and consideri...

This paper presents a model that complements the research stream of transaction cost economics with the dynamic capabilities approach. The paper shows that, even though technological alliances involving specific assets deployed in emerging industries are exposed to high transaction costs, they possess attributes that make them attractive. First, they facilitate the creation of tacit competencie...

This paper presents a new scheme for subdivision surfaces that is based on four-directional meshes. It combines geometry-sensitive refinement with convolution smoothing. The scheme has a simple, efficient implementation and generates well-shaped meshes which converge to smooth surfaces. keywords: subdivision schemes, four-directional meshes, quincunx lattice, refinenement, smoothing.
