Compression of the median nerve as it lies in the carpal tunnel can be caused by many lesions. Entin (1968) grouped them into three categories: those reducing the capacity of the tunnel, those increasing the volume of its contents, and those that form part of a systemic condition. Recently a case of the syndrome presented which fell into the second grouping: the cause was unusual and a search o...

We show that in the absence of any information about the ‘hidden’ target in terms of the observed sample path, and irrespectively of the distribution law of the observed process, the ‘median’ rule is optimal in both the space domain and the time domain. While the fact that the median rule minimises the spatial expectation can be seen as a direct extension of the well-known median characterisati...

The regressive nature of consumption taxes poses a challenge to partisan theory. Using data for up to 20 OECD countries in the period 1970-2003 this article aims to explore the question of whether the idea that social democratic governments typically have to compromise on policy goals and core constituency interests to make themselves more appealing to the median voter necessitates the use of r...

The p-median clustering model represents a combinatorial approach to partition data sets into disjoint, nonhierarchical groups. Object classes are constructed around exemplars, that is, manifest objects in the data set, with the remaining instances assigned to their closest cluster centers. Effective, state-of-the-art implementations of p-median clustering are virtually unavailable in the popul...

The subject of this paper are infinite, locally finite, vertex-transitive median graphs. It is shown that the finiteness of the Θ-classes of such graphs does not guarantee finite blocks. Blocks become finite if, in addition, no finite sequence of Θ-contractions produces new cut-vertices. It is proved that there are only finitely many vertex-transitive median graphs of given finite degree with f...

For J ≥ 2 independent groups, the paper deals with testing the global hypothesis that all J groups have a common population median or identical quantiles, with an emphasis on the quartiles. Classic rank-based methods are sometimes suggested for comparing medians, but it is well known that under general conditions they do not adequately address this goal. Extant methods based on the usual sample...

Two fast algorithms for median ltering of images using parallel computers having 2-D mesh interconnections are given. Both algorithms assume that an n n image is loaded onto the mesh with one processing element per pixel. One algorithm performs median ltering over d d neighborhoods in O(d 2 ) time and works with pixel values in an arbitrarily large range. This algorithm, while theoretically sub...

We develop a serial algorithm for separable median filtering that requires only two comparisons per element when the window size is three. In addition, fast parallel CREW PRAM algorithms with good processor-time product are developed for separable median filtering and two dimensional median filtering.

This paper presents a robust de-noising model for image enhancement using adaptive median filtering. In this approach image noise is detected with a standard median filter using an adaptive window. Within the window, the original value of the center pixel is changed to a newer that is closer to or same as the standard median. A comparison has been arranged among the proposed method, the standar...
