OBJECTIVES To consider how the impact of the NHS Health Technology Assessment (HTA) Programme should be measured. To determine what models are available and their strengths and weaknesses. To assess the impact of the first 10 years of the NHS HTA programme from its inception in 1993 to June 2003 and to identify the factors associated with HTA research that are making an impact. DATA SOURCES M...

In photovoltaic system installations worldwide, the use of bifacial technology has begun to be more frequent due reduction cost gap associated with manufacture modules compared monofacial, encouraged by technological maturation modules. This research focuses on assessing technical and financial viability a solar technology, comparing 4 scenarios different albedos (0.15, 0.2, 0.3 0.4) respect ba...

the impact of installing process control systems can be expected in terms of performance improvements through reduced operating costs.  since these installations impose considerable capital expenditure, the profitability of the new systems should be economically justified. controlled variable trend was reconstructed by a combination of simple waves, which provided a means to simulate the effect...
