BACKGROUND Tuberculosis (TB) caused by Mycobacterium tuberculosis is one of the leading causes of death from infectious diseases worldwide. Sputum smear microscopy remains the most widely available pulmonary TB diagnostic tool particularly in resource limited settings. A highly sensitive diagnostic with minimal infrastructure, cost and training is required. Hence, we assessed the diagnostic per...

Electromagnetic interference (EMI) is one of the serious problems in most electrical and electronic appliances including fluorescent lamps. The electronic ballast used to regulate the power flow through the lamp is the major cause for EMI. The interference is because of the high frequency switching operation of the ballast. Formerly, some EMI mitigation techniques were in practice, but they wer...

In this paper a compact representation, 3D Layered, Adaptive-resolution and Multi-perspective Panorama (LAMP), is proposed for representing large scale and 3D scenes with occlusion. Two kinds of 3D LAMP representations are constructed, i.e. the relief-like LAMP and the image-based LAMP, both of which concisely represent almost all the information from a long image sequence. The relief-like LAMP...

Energy-efficient lighting is one of the key measures for addressing electric power shortages and climate change mitigation, and fluorescent lamps are expected to dominate the lighting market in China over the next several years. This review presents an overview on the emissions and risk of mercury from fluorescent lamps during production and disposal, and discusses measures for reducing the mer...
