This paper studies a real-world problem arising in the area of motorail transportation. The considered problem deals with the loading of cars and motorcycles onto motorail wagons under realistic technical and legal constraints. The load planning problem, introduced as motorail transportation problem (MTP), occurs during the booking process and afterwards during the loading process at motorail t...

The recent notes by Broecker [1991] and by Smith and Mackenzie [1991] rightfully point out that many oceanographers do not have a clear grasp of the relationship between the oceanic biological pump and anthropogenic CO2 transient. This misunderstanding has unfortunately led some scientists to make misleading claims as to the importance of the biological pump in the anthropogenic transient. It i...

A survey carried out on 18 farms in Switzerland, Germany, Denmark and the Netherlands indicates current trends in cattle feeding. An increasing number of farms are relying on automatic feeding to ease their workload, save time and achieve flexibility. The farms surveyed were practical users of automatic feeding systems. There are various systems which permit the automation of feeding systems. A...

Rail freight activity in Britain has increased by almost 50% in the last ten years, with the movement of deep sea ISO containers between ports and inland terminals being a significant growth sector, with considerable further growth potential. High cube (9’6” height) ISO containers have become more prevalent, posing a considerable challenge for rail freight operators since much of the rail netwo...

In this paper we study a railway optimization problem known as the Train Unit Assignment Problem. A train unit consists of a self-contained train with an engine and a set of wagons with passenger seats. Given a set of timetabled train trips, each with a required number of passenger seats, and a set of train units, each with a given number of available seats, the problem calls for the best assig...

We present an approach to detecting and analyzing the 3D configuration of objects in real-world images with heavy occlusion and clutter. We focus on the application of finding and analyzing cars. We do so with a two-stage model; the first stage reasons about 2D shape and appearance variation due to within-class variation (station wagons look different than sedans) and changes in viewpoint. Rath...

Little is known about kindergarten students' active school transportation (AST) and stroller/wagon use as sedentary travel devices. The primary objective of this cross-sectional study was to determine the prevalence of kindergarten children arriving to school by active and sedentary modes, including strollers, in Toronto elementary schools and compare to students in kindergarten to grade 6 (K-6...

Emerging wireless sensor networking (WSN) and modern machine learning techniques have encouraged interest in the development of vehicle health monitoring (VHM) systems that ensure secure and reliable operation of the rail vehicle. The performance of rail vehicles running on railway tracks is governed by the dynamic behaviours of railway bogies especially in the cases of lateral instability and ...

Parents of young children will tell you that boys like different toys than girls; they are intrigued by Bob the Builder, Transformers of all kinds, trucks, police cars, front loaders, bikes, skate boards, and wagons. Girls too like bikes, cars and Legos, but also play with stuffed animals and dolls, toys that boys find less appealing for active play. Is this difference in toy preference due exc...

OBJECTIVE In order to compare their validity, this review applies scientific standards for sustaining the neuroses, the schizophrenias and bipolar disorders as separate "bona-fide" psychiatric diseases. The standards for disease validation demand specific and unique symptoms. METHOD We review a wide variety of clinical and basic science comparisons between schizophrenia and psychotic bipolar ...
