Abstract: Systems and methods are described that provide a Heat Flow Model (HFM) graph modeling methodology. Embodiments automatically translate formal HVAC system descriptions from a Building Information Model (BIM) into HFM graphs, and compile the graphs into executable FDD systems. During an engineering phase, a user interface is used to enter parameters, conditions, and switches not found in the BIM. During a runtime phase, real-time data from an HVAC control system is input to the generated FDD system (HFM graph) for fault detection and diagnosis.

Abstract: An accelerated screen codec technique is described that provides a general screen compression framework, which, in one embodiment, is Graphics Processor Unit (GPU) friendly. In one embodiment, in order to compress screen data, blocks in a compound screen image containing both images and text are segmented into text blocks and pictorial blocks using a simple gradient-based procedure. The text and pictorial blocks are then compressed respectively via different compression techniques. Additionally, a GPU acceleration architecture of one embodiment of the accelerated screen codec technique provides a screen codec that maximally exploits a GPU's high parallelism and reduces the download bandwidth from GPU to Computer Processing Unit (CPU).

Abstract: A method for compressing textures. A first block of texels is transformed from a red-green-blue (RGB) space to a second block of texels in a luminance-chrominance space. The first block has red values, green values and blue values. The second block has luminance values and chrominance values. The chrominance values may be based on a sum of the red values, a sum of the green values and a sum of the blue values. The chrominance values may be sampled for a first subset of texels in the second block. The luminance values and the sampled chrominance values may be converted to an 8-bit integer format. The luminance values of the first subset may be modified to restore a local linearity property to the first subset. The second block may be compressed into a third block.

Abstract: Progressive distributed video coding is described. In one implementation, video data maybe encoded by arranging the data into bit-planes. The arrangement of bit-planes is adapted by shifting the first non-zero bit-plane left by one place in the binary digits and moving the sign bit immediately in the place vacated by the shifted non-zero bit-plane. The adapted bit-planes are then encoded using an asymmetric Slepian-Wolf encoder.

Abstract: An on-line fault detection and avoidance method is provided for industrial control systems that include multiple interacting process controllers. The method addresses the problem that not all faults can be determined and removed at the time of system design and testing. When a fault translates into a time-out condition in one or more controllers, symptoms are identified, persistence is measured, other involved controllers are identified, the fault condition is identified and control laws are reconfigured to avoid the fault condition in the future.

Abstract: A technique is described for compressing textures for use in a graphics application, such as a 3D game application. The technique includes parsing first-compressed texture information (e.g., S3TC texture information) into respective components of the first-compressed texture information (such as main color information, color index information, main alpha information, and alpha index information). The technique then further compresses the respective components to yield second-compressed texture information (referred to as modified compressed texture information or MCT texture information). The MCT texture information can be stored and then decoded to reconstruct the original S3TC texture information for use in the graphics application. Compared to the use of unmodified S3TC texture information, the technique allows more economical storage of texture information, as well as more efficient loading of the texture information from storage to memory.
