A tandem AGV configuration connects all cells of a manufacturing area by means of non-overlapping, sin-gle-vehicle closed loops. Each loop has at least one additional P/D station, provided as an interface between adjacent loops. This study describes the development of three tabu search algorithms for the design of tandem AGV systems. The first algorithm was developed based on the basic definiti...

BACKGROUND Peripapillary loops of venous origin are extremely rare. CASE A 55-year-old woman was referred to us for further examination of peripapillary vascular abnormalities. OBSERVATIONS Fundus examination and fluorescein angiography clearly showed a venous and an arterial peripapillary loop in both her right and left fundi. The venous loop in the right eye was in a large hairpin configu...

We study incidence properties among cosets of finite loops, with emphasis on well-structured varieties such as antiautomorphic loops and Bol loops. While cosets in groups are either disjoint or identical, we find that the incidence structure in general loops can be much richer. Every symmetric design, for example, can be realized as a canonical collection of cosets of a finite loop. We show tha...

1 The hard X-ray flux ratio ℜ of the footpoint sources to the loop-top source has been used to investigate non-thermal electron trapping and precipitation in solar flares. Considering the mission-long Yohkoh Hard X–ray Telescope database, from which we selected 117 flares, we investigated a dependence of the ratio ℜ on flare loop parameters like height h and column depth N. We used non-thermal ...

Simple modifications are introduced to the evolvable self-reproducing CA (Evoloop) implemented by Sayama [4] with the aim of mimicking a predator-prey model. A new state to represent the predator (disease) and a corresponding rule set are added to the CA, as well as a memory layer to track predator lifetime. Behaviour of the modified system is investigated and compared for different choices of ...

We have contrived the evoloop 5, 6 , a new selfreproducing loop spontaneously evolving on a simple deterministic 9-state 5-neighbor cellular automata (CA) space. In this article, we examine the evolvability and adaptability of the evoloop through several experiments, the result of which brings us good prospects for the future implementation of an extraordinary large-scale arti cial ecosystem on...

Abstract Objective: Since the development of new deep brain stimulation (DBS) devices in recent years, there is an increased need for assessing safety combination with transcranial magnetic (TMS). Methods: We applied a combined ex vivo and computational approach to investigate TMS using Boston Scientific segmented electrode. TMS-induced current was measured between electrode lead extension, dif...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014208544 DESCRIPTION A 58-year-old woman presented with acute abdominal pain and vomiting of 3 days duration. She had undergone laparotomy for appendicular perforation 25 years earlier. She had recurrent episodes of abdominal pain for the past 5 years and was being treated as a case of adhesi...

Loop tiling is a fundamental optimization for improving data locality. Selecting the right tile size combined with the parallelization of loops can provide additional performance increases in the modern of Chip MultiProcessor (CMP) architectures. This paper presents a runtime optimization system which automatically parallelizes loops and searches empirically for the best tile sizes on a scalabl...
