The objective of this study was to investigate the contribution of handgrip strength in predicting the functional outcome after hip fracture in women.We prospectively investigated white women (N = 193 of 207) who were consecutively admitted to a rehabilitation hospital after a hip fracture. We measured handgrip strength with a Jamar dynamometer (Lafayette Instrument Co, Lafayette, IN), on admis...

The exploitation of the residual redundancy of source codec parameters by using the Turbo principle is known as iterative source-channel decoding (ISCD). The concept of redundant index assignments was proposed as a powerful improvement for ISCD. In this contribution design and optimization guidelines for such redundant index assignments are presented. Commonly, the redundant index assignment is...

We show that the maximin average redundancy in pattern coding is eventually larger than 1.84 ( n logn )1/3 for messages of length n. This improves recent results on pattern redundancy, although it does not fill the gap between known lowerand upper-bounds. The pattern of a string is obtained by replacing each symbol by the index of its first occurrence. The problem of pattern coding is of intere...

In spatial database systems rectangles are commonly used to approximate real spatial data. A technique that approximates extended objects with a collection of rectangles is the z-ordering method. Since each of these rectangles eventually corresponds to an entry in a spatial index, the object may be refer-enced several times. This redundancy eeect is controllable. In this paper, we present an em...

The error robustness of digital communication systems using source and channel coding can be improved by iterative sourcechannel decoding (ISCD). The turbo-like evaluation of natural residual source redundancy and of artificial channel coding redundancy makes step-wise quality gains possible by several iterations. The maximum number of profitable iterations is predictable by an EXIT chart analy...

Association rule mining is known to be computationally intensive, yet real-time decision-making applications are increasingly intolerant to delays. In this paper, we introduce the parameter space model, called PARAS. PARAS enables efficient rule mining by compactly maintaining the final rulesets. The PARAS model is based on the notion of stable region abstractions that form the coarse granulari...

It is known that among all redundancy-free codes (or index assignments), the natural binary code minimizes the mean-squared error (MSE) of the uniform source and uniform quantizer on a binary symmetric channel. We derive a code which maximizes the MSE and demonstrate that the code is linear and its distortion is asymptotically equivalent, as the blocklength grows, to the expected distortion of ...

A sample of 78 Pinus radiata D. Don logs was measured and sawn to maximise yields of 100 x 50-mm and 200 x 50-mm timber. The average bending strength and stiffness of the timber were found to depend on the basic density of the log but the lower fifth-percentile strength was more dependent on branch index. For the 28-year-old stand sampled, logs with a low branch index yielded 100 x 50-mm timber...

Redundancy allocation problem is one of most important problems in reliability area. This problem involves with the suitable redundancy levels under certain strategies to maximizing system reliability under some constraints. Many changes have been made on this problem to draw the problem near to real situations. Selecting the redundancy strategy, using different system configuration are some of...

In this work we propose to use an approach based on genetic algorithms to obtain analytical redundancy relations to study the diagnosability property on a given continuous production system. Diagnosability analysis for production systems examines the detectability property (the faults are discriminable from the normal behavior of the system) and the isolability property (the faults are discrimi...
