In this paper we propose a centralized control method for routing and scheduling fleet of autonomously guided vehicles that serves online transportation requests. Our maintains central schedule, which is revised each time vehicle finishes its current task or new request arrives. The main benefit the schedule it ensures provably conflict-free large on almost any layout, permits optimization taki...

A systematic study of collisions between surfactant-free organic drops in aqueous electrolyte solutions reveals the threshold at which continuum models provide a complete description of thin-film interactions. For collision velocities above ~1 μm/s, continuum models of hydrodynamics and surface forces provide a complete description of the interaction, despite the absence of surfactant. This inc...

Various joining methods are available for composite structures, with anticipated benefits for the most obvious way of exploiting the nature of thermoplastic materials: melting and reconsolidation. A proper joint selection and detailed design, however, will require quantitative results obtained in an objective and reproducible procedure. The objective of this paper was to develop benchmark proce...

We reconstructed from electron micrographs of 189 serial ultrathin sections a major portion of the dendritic tree of an on-beta ganglion cell through its sixth order of branching. One hundred three contacts from three cone bipolar cells were identified. Forty-seven contacts were from a single CBb1 cone bipolar. These were distributed widely over the dendritic tree but were frequently found on t...

Using 3D kinetic data, this study was undertaken to determine whether similar joint muscle power activities or mechanical energies are developed for dynamic stability and propulsion during the gait of healthy elderly and young individuals’ dynamic stability. Eighteen elderly (71±6.8 years) and 18 young (25±4.1 years) able-bodied male subjects walked along a 10 m walkway at a freely-chosen speed...

Introduction. Dopamine-replacement medications may improve mobility while not improving responses to postural challenges and could therefore increase fall risk. The purpose of this study was to measure reactive postural responses and gait-related mobility of patients with PD during ON and OFF medication conditions. Methods. Reactive postural responses to the Pull Test and performance of the Fun...

The static pull-in instability of beam-type micro-electromechanical systems is theoretically investigated. Two engineering cases including cantilever and double cantilever micro-beam are considered. Considering the mid-plane stretching as the source of the nonlinearity in the beam behavior, a nonlinear size-dependent Euler-Bernoulli beam model is used based on a modified couple stress theory, c...

This work studies a functional correlation between different texture parameters and the adherence of NiP coating on metal substrate. Multiple surfaces with milling feed rate coated went through pull-off adhesion test. study determined analysis characterization surface topographies strength measured during In order to if multi-scale approach improve correlation, “conventional” method based ISO 2...

The allocation of inventory ownership affects the inventory availability in a supply chain, which in turn determines the supply chain performance. In this paper, we consider a supplier-retailer supply chain in which the supplier starts production well in advance of the selling season, and the retailer is offered two ordering opportunities at different points in time. An early order is allowed b...

Globally, many women are still disadvantaged when it comes to business opportunities. Entrepreneurship development programs, specifically designed to assist women entrepreneurs, are assisting in solving this problem to a certain extent. The purpose of this study is to identify the factors that motivate females to start their own business. Females, from three different groups (2013, 2014 and 201...
