To improve operations commonly found in today's crossdocks, we offer a door assignment optimization tool that will reduce the distance travelled by goods across the crossdock, as well as workload and labor cost. The cross dock door assignment problem (CDAP) minimizes total distance travelled by the goods inside the crossdock where door capacities are limited by the time they can be used in a wo...

Vision guides flight behaviour in numerous insects. Despite their small brain, insects easily outperform current man-made autonomous vehicles in many respects. Examples are the virtuosic chasing manoeuvres male flies perform as part of their mating behaviour and the ability of bees to assess, on the basis of visual motion cues, the distance travelled in a novel environment. Analyses at both the...

Semantic similarity measures have focused on individual word senses. However, in many applications, it may be informative to compare the overall sense distributions for two different contexts. We propose a new method for comparing two probability distributions over WordNet, which captures in a single measure the aggregate semantic distance of the component nodes, weighted by their probability. ...

Introduction: Since 2006, the number of seriously injured bicyclists in The Netherlands has increased significantly. This is also the case for sport cyclists. Over 80% of sport cyclists are male. We propose three factors that may contribute to involvement in sport cycling crashes among males: Bunch riding (cycling in a group), the inflow of sport cyclists with little experience and a competitiv...

Abstract Aim To assess the impact of simulated laparoscopic trainers on improving surgical trainees’ technical ability in completing a appendicectomy by measuring effect completion time and distance travelled with standard instruments. Method Six CT1 (early-stage) trainees little prior operative exposure were selected from North-West England Deanery to perform x10 exercises Augmented Reality La...

A modified chemotaxis chamber was used to evaluate cellulose acetate/nitrate filters for the measurement of dog sperm motility. The distance travelled into the filters was affected by filter pore size, incubation time and sperm concentration. After storage of spermatozoa at 37 degrees C the distance penetrated into the filters reflected the deterioration of the sample, but was not as sensitive ...

Odometry is the most widely used navigation method for mobile robot positioning. In this paper motion control and positioning for a mobile robot working in a warehouse is presented. Odometry system configuration and wheel encoder used are detailed. The calculations of the distance travelled compared to the actual measured distance show some difference that are due to internal and external cause...

Escape performance is fundamental for survival in fish and most other animals. While previous work has shown that both intrinsic (e.g. size, shape) and extrinsic (e.g. temperature, hypoxia) factors can affect escape performance, the possibility that behavioural asymmetry may affect timing and locomotor performance in startled fish is largely unexplored. Numerous studies have found a relationshi...

The purpose of the present study was to evaluate the relationship between spatial awareness, agility, and distance covered in global positioning system (GPS) derived velocity zone classifications during a collegiate rugby match. Twelve American collegiate rugby union players (mean±SD; age: 21.2±1.4 y; weight: 85.0±16.0 kg; 7 forwards & 5 backs) on a single team volunteered to participate in thi...
