This paper presents a solution approach to optimize vehicle routes for a multi-depot, multi-vehicle, pickup and delivery problem over a large ground transportation network.More precisely, we address ground transportation of orders for the Canadian Department of National Defence using heterogeneous vehicle fleets.The fleets consist of limited Cart -
Cardiovascular diseases (CVDs) are consider the main cause of death today According to World Health Organization (WHO),and because that ECG signal is very important tool in monitoring and diagnosis of these disease , different automatic methods were proposed based on this signal.[1].The manual analysis of ECG signals is suffered different challenge
In this paper, 8 loading strain rates were configured to carry out experimental research on the compressive dynamic behaviors of plain concrete (PC) and lightweight aggregate concrete (LWAC) by utilizing a hydraulic servo machine.The compressive failure modes and stress-strain curves of PC and LWAC under various loading states were generated from t
The requirements of low Earth orbit (LEO) satellite systems for high-precision and selective multiple coverage, have driven much interest and demand for millimeter-wave multibeam antennas.However, the key challenge is to provide fully independent control of each beam with a single source, and metasurfaces have paved the way to solve this problem.He
