In the development of video and multimedia standards, new algorithms often result from the need to improve the efficiency or to reduce the cost of implementation. On the other hand, new implementation techniques are often triggered by algorithms that are too computation intensive with existing technology. Therefore, in multimedia applications, the development of algorithms and the progrless in ...

In this contribution, a design space exploration of the various possible schemes for all-digital symbol timing adjustment of QAM signals is made. The exploration is guided by both performance degradation and implementation cost considerations. The BER performance degradation is obtained using a quasi-analytic simulation approach, while the implementation cost is estimated by high level digital ...

The development of 3D printing for the manufacturing of prostheses and orthoses has resulted in cost reduction strategies, better accessibility and customization of prosthetic designs. The widespread use of 3D printing and the existence of myriad prosthetic designs available on the internet allows clinicians and researchers from different disciplines to manufacture their own devices. Given the ...

In earlier work we proposed a framework to integrate heterogeneous geospatial utility data in the UK. This paper provides an update on the techniques used to resolve semantic and schematic heterogeneities in the UK utility domain. Approaches for data delivery are discussed, including descriptions of three pilot projects and domain specific visualization issues are considered. A number of practi...

Implementing health information technology (IT) is a major strategic objective for providers. To pinpoint considerations that tie to success, the Premier health care alliance surveyed hospitals to develop an electronic health record best-practices library. Compiled from diverse health care organizations, the library outlines considerations to support "meaningful use" in the areas of computerize...

In recent years, there has been significant investment from both the private and public sectors in the development of diagnostic technologies to meet the need for human immunodeficiency virus (HIV) and tuberculosis testing in low-resource settings. Future investments should ensure that the most appropriate technologies are adopted in settings where they will have a sustainable impact. Achieving...

Patent law has relied in part on ethical considerations since its inception in Europe. Such considerations have been introduced more recently in the United States. Whereas the EU Directive on the protection on the occasion of the Human Genome Project of biotechnological inventions was intended to foster economic development in Europe, its implementation is outweighted by controversy about paten...
