ASRS is usually installed in a factory or warehouse to increase storage capacity, floor space utilization, labor productivity in storage operations and stock rotations etc. ASRS systems are custom-planned for each individual application, and they range in complexity from relatively small mechanized systems that are controlled manually to very large computercontrolled systems that are fully inte...

BACKGROUND Modelling travel time to services has become a common public health tool for planning service provision but the usefulness of these analyses is constrained by the availability of accurate input data and limitations inherent in the assumptions and parameterisation. This is particularly an issue in the developing world where access to basic data is limited and travel is often complex a...

Many of the analyses of time series that arise in real-life situations require the adoption of various simplifying assumptions so as to cope with the complexity of the phenomena under consideration. Whilst accepting these simplifications lead to heuristics that provide less accurate, compared to the full analytical description, representation of the phenomena, the intelligent choice of the simp...

The need to understand and forecast individual travel behavior over longer periods of time and space has placed tremendous stress on available data collection and modelling techniques. Traditional travel survey methods tend to focus exclusively on observed choices, using diary and stated preference techniques. However, improving our understanding requires more than just an improved accounting o...

Split-hom together structure is a new heavy load rack structure, and its reliability needs to be verified. Through analyzing multimodal hom-connection principle from the perspective of bionics and contact mechanics, the article puts forward three kinds of hom-connection methods and establishes the finite element model and mathematical model of the rack. Afterwards, the finite element model and ...

The load-balanced switch architecture is a promising way to scale router capacity. It requires no centralized scheduler, requires no memory operating faster than the line-rate, and can be built using a fixed, optical mesh. In a recent paper we explained how to prevent packet mis-sequencing and provide 100% throughput for all traffic patterns, and described the design of a 100Tb/s router using t...

Background. The number of students with Attention Deficit/Hyperactivity Disorder (ADHD) enrolled in colleges and universities has increased markedly over the past few decades, giving rise to questions about how best to document symptoms and impairment in the post-secondary setting. The aim of the present study was to investigate the utility and psychometric properties of a widely-used rating sc...
