From September 1995 to July 1996 50 patients were treated for carpal tunnel syndrome as outpatients by endoscopic release in the rooms of an orthopaedic surgeon (two-portal-technique). The average age was 51.3 years (27-61 years). The average length of symptoms was 43 months, the postoperative time off work averaged 27 days. Six months postoperatively wasting of the thenar persisted in 2 out of...

This paper proposes the use of a vector of color histogram peaks as an efficient and effective way for many image indexing problems. It shows that histogram peaks are more stable than general histogram bins when there are variation of scale and/or scale. We also introduce the structure of a room recognition system which applies this indexing technique to omni-directional images of rooms. Experi...

Two puzzles that repeatedly appeared in the Munich newspaper tz are Knossos and The Hour-Glass (“Das Stundenglas”) [Bul10a, Bul10b, Bul10c, Bul11], see also [Pre]. Knossos asks the reader to insert walls into a grid of cells representing the famous palace of Knossos. Every room is described by a number that indicates the length of its walls in terms of segments enclosing the room (we assume tha...

Background: High density concrete is extensively used for efficient radiation attenuation in radiotherapy rooms and nuclear reactors. Over the past eight years, some efficient galena-based concrete samples for shielding X or gamma rays was produced. The goal of this study was to produce a novel high density concrete against neutron and photon radiations using tourmaline and galena. Materials an...

Abstract In this paper, we study two well‐known problems that are attracting increasing attention in the last years: patient admission and patient‐to‐room assignment problems. These often complicated by some patients, which may have fluctuations length of stay (LOS). We propose an optimization model plans admissions stays considering LOS does not allow overcrowded rooms, as typically required r...
