The interest in self-reciprocal polynomials in coding theory originated with Massey (1963, 1964), who has shown tha t whenever a self-reciprocal polynomial is used as a convolutional code-generating polynomial, the resulting code may be decoded backward us well as forward, with the same hardware and the same probabil i ty of decoding error. Let G( D ) = go 4glD 4g~D ~ 4" . . 4g , D ' , where n ...

In this paper, we develop a novel 8 8 twodimensional (2-D) discrete cosine transform/inverse discrete cosine transform (DCT/IDCT) architecture based on the direct 2-D approach and the rotation technique. The computational complexity is reduced by taking advantage of the special attribute of complex number. Both the parallel and the folded architectures are proposed. Unlike other approaches, the...

How to collect data energy-efficiently from sensor nodes is an important research issue in wireless sensor networks. In this paper, we address the problem of gathering data from sensor nodes using a model-aided data gathering approach. In our approach, a model is maintained by a node and a replica of the model is maintained the base station. The base station uses the replica model to estimate t...

We present results of experiments testing the Fast Gauss Transform, Improved Fast Gauss Transform, and Dual-Tree methods (using kd-tree and Anchors Hierarchy data structures) for fast Kernel Density Estimation (KDE). We examine the performance of these methods with respect to data set size, dimension, allowable error, and data set structure (“clumpiness”), measured in terms of CPU time and memo...

In this paper, a robust adaptive control scheme with an intelligent supervisor for vehicle powertrain systems is investigated. The control objectives are to provide smooth shift transients for passenger comfort and to improve components durability. The reaction carrier speed and the turbine speed during the inertia phase are controlled to track their desired speeds. The boundedness of all signa...

An effective error handling mechanism plays an important role to ensure the reliability and robustness of the application of controller area network (CAN) in controlling dynamic systems. This paper addresses a new online error handling approach or named per-sample-error-counting (PSeC) technique that tends to replace native error handling protocol in controller area network (CAN). The mechanism...

A long-standing practice in clinical laboratories has been to automatically repeat laboratory tests when values trigger automated "repeat rules" in the laboratory information system such as a critical test result. We examined 25,553 repeated laboratory values for 30 common chemistry tests from December 1, 2010, to February 28, 2011, to determine whether this practice is necessary and whether it...

Assembly errors can occur in a robotic assembly system. In this paper, a method that predicts an assembly error is proposed. It considers that assembly errors occur under the condition that the geometric trajectory of a mated part and the relational position and orientation of a base part are outside the allowable tolerance. A certain point, which is determined by using a physical light reflect...

Spaced seeds have been shown to be superior to continuous seeds for efficient and sensitive homology search based on the seedand-extend paradigm. Much the same is true in genome mapping of high-throughput short-read data. However, a highly sensitive search with multiple spaced patterns often requires the use of a great amount of index data. We propose a novel seed-set construction method for ef...
