Bike sharing systems consist of a fleet of bikes placed in a network of docking stations. These bikes can then be rented and returned to any of the docking stations after usage. Predicting unrealized bike demand at locations currently without bike stations is important for effectively designing and expanding bike sharing systems. We predict pairwise bike demand for New York City’s Citi Bike sys...

TThe uncertainty estimation and compensation are challenging problems for the robust control of robot manipulators which are complex systems. This paper presents a novel decentralized model-free robust controller for electrically driven robot manipulators. As a novelty, the proposed controller employs a simple Gaussian Radial-Basis-Function Network as an uncertainty estimator. The proposed netw...

Resource scarcity is a common challenge in mobile and embedded computing. Mobile and embedded devices are typically battery-driven. Thus, their energy demand is in the focus of attention. Various techniques for saving energy exist; Their evaluation warrants approaches for measuring the energy demand during the use of the devices. Modern smart-phones offer sensors and corresponding APIs for gath...

In the current economic, resource and carbon constrained climate, it is imperative that power distribution companies invest in only necessary network augmentation. However, with electricity demand growth over recent years doubling the electricity consumption growth, capital expenditure is following in a similar fashion relative to operational expenditure [1]. The need for greater infrastructure...

Why RF test on-wafer? Introduction The ever-increasing demand for more bandwidth to support the exploding Internet and the insatiable need for PCS (personal communication systems)/cellular devices has driven manufacturers of high speed digital and RF devices to push RF test of these devices upstream to the wafer level for a variety of reasons. Internet user demand for bandwidth is doubling ever...

In hybrid electric vehicles (HEVs), the power network takes an ever-important role, which functions to adjust the engine operating region for less emissions, to incorporate the electric machine for higher overall efficiency, and to feed the increasing demand of electric loads with different voltage levels. Furthermore, more and more mechanically, pneumatically or hydraulically driven systems ar...

The current methods of the development and implementation of a Data Warehouse (DW) don’t consider the integration with the business-processes (organizational-processes and theirs respective data). In addition to these current methods, based on demand-driven, data-driven and goal-driven, we will introduce in this paper a new approach to DW development and implementation. This new approach will b...

Networked Infrastructure systems deliver services and/or products from point to point along the network. Demand for the services provided by such systems is typically cyclic, creating inefficiencies in capacity utilization. Congestion pricing provides incentives to shift demand from peak time periods to lower demand periods. This effectively increases the capacity of the system without the need...

The authors develop a conceptual framework of the factors that motivate a retailer’s decision to rely on demand conditions and past prices in setting current and future prices. Specifically, they examine the circumstances under which retailers choose demand-based pricing versus past-price dependence for different brands and categories. Given scarce resources and costs of price adjustments, dema...

An aging population and an increase in chronically ill patients demand teamwork treatment models. To support these with information systems, interoperability is a prerequisite. Model-driven software development (MDSD) with special healthcare extensions can enable reuse of components and improve conformance to international standards. In this paper, a MDSD HealthCare Framework is proposed and de...
