Effects of bit geometry in multiple bit-rock interaction
The impact of bit-coal/rock interaction during the cutting process in underground mines is great concern to the mining community of the world. Rock/coal cutting bears directly on rock/coal dust generation that causes "black lung/silicosis" in miners. On the other hand, rock cutting generates …

Commercialization of bit-patterned media
… terabyte-domain. In such a high areal density, bit-patterned media is a promising candidate to overcome the superparamagnetic limit faced by the conventional continuous media. However, the patterned media concept has not been realized in mass production due to several reasons. Beside the …

A Little Bit of first Grade
The production of a sound filmstrip that will introduce parents to first grade work--methods and materials. This media of communication will clearly acquaint the parents with the program and provide the teacher with sufficient time for discussion of school rules, practices, and procedures. Special …

Bit-rate selection in wireless networks
This thesis evaluates bit-rate selection techniques to maximize throughput over wireless links that are capable of multiple bit-rates. The key challenges in bit-rate selection are determining which bit-rate provides the most throughput and knowing when to switch to another bit-rate that would …

Testing and Understanding Screwdriver Bit Wear
… of how to design and test Phillips screwdriver bits. Wear is the primary concern in applications where the bit is used in a power driver. Such applications include drywalling, decking and other construction and home projects. To pursue an optimal design, designers must have an understanding how …

Programming Languages for Bit-Serial Array Machines
Many high-level languages have been created or are under development for large nearest-neighbor connected multiprocessors, such as the ILLIAC IV, the ICL DAP, and the Goddard-Goodyear MPP. These higher-level languages are intended to make these machines easier to program.

Hardware implementation of wireless bit rate adaptation
… a hardware implementation of the SoftRate bit-rate adaptation protocol. SoftRate is a new bit-rate adaptation protocol, which uses per-bit confidence hints generated by the convolutional decoder to estimate the channel bit-error rate. Implementing SoftRate requires changes to both the …

Multiple bit error correcting architectures over finite fields
… thesis proposes techniques to mitigate multiple bit errors in GF arithmetic circuits. As GF arithmetic circuits such as multipliers constitute the complex and important functional unit of a crypto-processor, making them fault tolerant will improve the reliability of circuits that are employed in …

Bit-Stream Control of Doubly Fed Induction Generators
… for implementing digital control systems is the Bit-Stream control technique. In contrast to the usual methods of implementing digital controllers, Bit-Stream control systems are developed using standard schematic editors provided by FPGA manufacturers. Provided that the desired control functions …

Loss Concealment for Low -Bit -Rate Packet Voice
… correlations in linear predictors of low-bit-rate coders, but low correlations in excitation parameters. Hence, we generate multiple descriptions at the sender side by interleaving linear predictors, and reconstruct lost ones at the receiver side by linear interpolations. In addition, we …

A classification of reversible bit and stabilizer operations
… of classical reversible gates acting on bits in terms of the reversible transformations they generate, which was recently completed by the author, Scott Aaronson, and Luke Schaeffer. In particular, we present those portions of the classification which were the main contributions of the …

Rate control and bit allocations for JPEG transcoding
… zero-valued quantized DCT coefficients and the bitrate. Using this relationship and a histogram of coefficients, it is possible to determine an effective way to scale the quantization tables of an image to approach a target filesize. As the image is being transcoded, an intra-image process makes …

Low bit-rate speech encoding for digital mobile radio
The need for low bit-rate speech coding is the result of growing demand on the available radio bandwidth for mobile communications both for military purposes and for the public sector. To meet this growing demand it is required that the available bandwidth be utilized in the most economic way to …
