Methods and apparatus for a new approach to the problem of finding communities in complex networks relating to a social definition of communities and percolation are disclosed. Instead of partitioning the graph into separate subgraphs from top to bottom a local algorithm (communities of each vertex) allows overlapping of communities. The performance of an algorithm on synthetic, randomly-generated graphs and real-world networks is used to benchmark this method against others. An heuristic is provided to generate a list of communities for networks using a local community finding algorithm. Unlike diffusion based algorithms, The provided algorithm finds overlapping communities and provides a means to measure confidence in community structure. It features locality and low complexity for exploring the communities for a subset of network nodes, without the need for exploring the whole graph.

A software application, which presents aggregated content including broadcast, Internet, and local media on a single HDTV display screen. For the most part, this information is pulled from existing databases and supplied by means of an entertainment portal, and then synchronized, resized, and displayed on a single HDTV display screen. This allows mixed entertainment content from creators, broadcasters, advertisers, manufactures, websites, and home consumers to be viewed on a single HDTV display screen, thereby creating a single-screen home entertainment experience. In operation, the screen is divided into multiple areas 200, 202 where web content, which can be continuously updated, is displayed at the same time live video is being aired. This can include any and all types of content; such as news, stock quotes, weather forecast, sports scores, on-line shopping, on-line multi-player games, local community information, etc.

A method for counting individuals in an image containing a dense, uniform or non-uniform crowd. The current invention leverages multiple sources of information to compute an estimate of the number of individuals present in a dense crowd visible in a single image. This approach relies on multiple sources, such as low confidence head detections, repetition of texture elements (using SIFT), and frequency-domain analysis to estimate counts, along with confidence associated with observing individuals in an image region. Additionally, a global consistency constraint can be employed on counts using Markov Random Field. This caters for disparity in counts in local neighborhoods and across scales. The methodology was tested on a new dataset of fifty (50) crowd images containing over 64,000 annotated humans, with the head counts ranging from 94 to 4,543. Efficient and accurate results were attained.

A short wave omnidirectional antenna for the 26 Megahertz band provides line-of-sight broadcasting at comparatively low power to serve local communities while suppressing sky wave propagation. Sky wave suppression is achieved by a critically configured reflector above the radiator or by a co-located second active or parasitic radiator spaced to achieve sufficient beam tilt to create a null at critical angles, generally from the horizon to thirty degrees above. This arrangement allows local broadcasts to be originated at numerous sites despite the narrow extent of the band (330 kHz) and the narrow (10 kHz) channel width. Among other possible applications, the antenna supports transmission using the Digital Radio Mondiale® (DRM®) system for COFDM. COFDM technology can suppress ghosting and most noise, while low emission angle of the antenna and low intended transmitter power largely prevent interference between broadcasts at moderate distances.
