A purely interferometric algorithm, named imaging has been developed for mapping lightning in the low-frequency band. The algorithm locates a source by computing three-dimensional correlation of signals arriving at pair sensors, and then summing correlations all antenna pairs. This does not locate solving non-linear time-of-arrival (TOA) equations, instead is located global maxima total correla...

Aerosol particles can strongly affect both air quality and the radiation budget of the atmosphere. Above Beijing, the capital city of China, large amounts of aerosols within the atmospheric column have caused the deterioration of local air quality and have influenced radiative forcings at both the top and the bottom of the atmosphere (BOA and TOA). Observations of aerosol radiative forcing and ...

The influence of oceanic constituents on the polarized reflectance measured at the top of atmosphere (TOA) over open ocean waters in one visible band is investigated. First, radiative transfer modelling is used to quantify the effects of biomass concentration on the TOA polarized signal for a wide range of observation geometries. The results showed that the TOA polarized reflectance remains ins...

Wireless capsule endoscope (WCE) has become one of the most popular inspection devices which provides visual investigation of entire gastrointestinal (GI) tract. While the other traditional (wired) endoscopic devices are usually used for colon and stomach inspection. Locating abnormalities such as tumors, polyps and bleedings with wireconnected endoscope in GI tract is simple as long as we coul...

PURPOSE The transobturator adjustable tape (TOA) sling operation is an effective procedure that allows for correction of postoperative incontinence or obstruction through adjustment of the mesh tension. During the operation, the outer cylinder of a ballpoint pen was used for proper mesh placement with less dissection. We evaluated the efficacy and safety of the TOA sling operation with the use ...

Improving accuracy in wireless localization and ranging is a challenging task which often demands an increase in the signal-to-noise ratio (SNR). Impulsive ultra-wideband (UWB) technology is a promising signaling alternative that is capable of high-resolution ranging with minimal cost on SNR. Unfortunately, typical UWB time-of-arrival (ToA) estimators are complicated and perform poorly in the l...

Time-of-arrival (TOA) estimation is the first step of the most positioning algorithms. However in various environments especially when ultra wideband (UWB) pulses are used, TOA extraction from the received signal is challenging. UWB radio propagation bears multipath phenomenon, therefore correct identification of the first path TOA highly depends on the statistical characteristics of the enviro...

Abstract Tradeoff Analysis (TOA) is an approach to positive analysis that combines foresight and simulation modeling tools from the relevant disciplines, including economics, in a participatory process designed formulate evaluate forward-looking, strategic decisions under high levels of uncertainty complex systems. We motivate TOA with prototype framework for design evaluation public-good agric...
