The impression of a piece of footwear can potentially lead to 3 identifications, of increasing accuracy; a shoe of a certain size, a shoe of a certain make or a specific shoe. The quality of the print will usually dictate which of these is possible. A vague outline is unlikely to provide conclusive evidence, but could offer some information about the size, and in some cases the brand of a shoe....

The purpose of this work is to develop a system for supporting Internet footwear sales. The goal is to increase the accuracy of the shoe size and model selection when buying in the Internet. We propose a recommendation system which improves the classification accuracy and is based on foot and/or shoe scanners. 271 adult subjects participated in this study. The subjects were asked to estimate th...

BACKGROUND Knowing the timing of the pubertal growth spurt of the spine, represented by sitting height, is essential for the prognosis and therapy of adolescent idiopathic scoliosis. There are several indicators that reflect growth or remaining growth of the patient. For example, distal body parts have their growth spurt earlier in adolescence, and therefore the growth of the foot can be an ear...

The fishery of Lake Victoria became a major commercial fishery with the introduction of Nile perch in 1950s and 1960s. Biological and population characteristics point to a fishery under intense fishing pressure attributed to increased capacity and use of illegal fishing gears. Studies conducted between 1998 to 2000 suggested capture of fish between slot size of 50 to 85 cm TL to sustain the fis...

The asymptotic covariance matrix of the empirical cepstrum is analyzed. We show that for Gaussian processes, cepstral coefficients derived from smoothed periodograms are asymptotically uncorrelated and their variances multiplied by the sample size T tend to unity. For an autoregressive process and its autoregressive cepstrum estimate, somewhat weaker results hold.

Two novel suboptimal algorithms for mutual exclusion in distributed systems are presented. One is based on the modiication of Maekawa's grid based quorum scheme. The size of quorums is approximately p 2 p N where N is the number of sites in a network, as compared to 2 p N of the original method. The method is simple and geometrically evident. The second one is based on the idea of diierence set...

Shoeprint information is gathered from crime scenes by photography, a cast or electrostatic lifting. This impression is then used to arrive at three main types of classification. Firstly there is the basic match in shoe size, secondly matching a shoe print to a particular brand or model. This can be achieved by keeping a database of product information from shoe manufactures (this data is abund...

In Gold’s influential language learning paradigm a learning machine converges in the limit to one correct grammar. In an attempt to generalize Gold’s paradigm, Case considered the question whether people might converge to vacillating between up to (some integer) n > 1 distinct, but equivalent, correct grammars. He showed that larger classes of languages can be algorithmically learned (in the li...

The purpose of this study was to determine if ground reaction forces were influenced by shoe design (adult vs. youth) for female children when running. Subjects (n = 10, 12.0 ± 1.1 years old; 154 ± 4.9 cm; 46.2 ± 14.3 kg; shoe size 3.5-7 youth) were fit with a shoe model available in youth and adult sizes. Subjects ran 10 trials per shoe condition across a force platform placed in the middle of...

This study investigates preschoolers’ ability to perceive the heaviness of objects by dynamic touch, a perceptual system that relies on the use of the muscle as a sensory organ. In total, 18 preschoolers were asked to hold objects by a handle without being able to see them. The 9 objects differed in mass and volume, allowing us to test the size–weight illusion by dynamic touch. Children were as...
