Proactive scheduling aims at the generation of robust baseline schedules, which has been studied for many years with assumption that activity splitting is not allowed. In this paper, we focus on proactive resource-constrained project problem in each can be split discrete time instants under constraints a maximum number and minimum period continuous execution. problem, setup times are also considered. A mathematical model established analyzed, two properties one lemma proposed. As proved to...
Large-area and conformal piezoelectric elements are highly desired for acoustic transducers to possess a large power source level wide detecting range. To date, single-crystal piezocomposites attract much attention on enhancing the bandwidth next-generation transducers, owing their higher electromechanical coupling properties compared traditional piezocomposites. Unfortunately, it is still challenging achieve large-area because of fragile nature, anisotropy, limited grown size single...
Alternating current polarization (ACP) has been demonstrated to enhance the performance of 1-3 piezoelectric single crystal composites (PSCCs), compared direct (DCP). However, scaling effect and temperature stability PSCCs under different modes, which are significance practical applications, have rarely studied. Here, we analyzed thickness temperature-dependent properties ACP DCP. The results indicated that improved piezoelectric, electromechanical coupling, dielectric properties. There were...
In this paper, we investigate the resource-constrained project scheduling problem with resource transfer times under uncertain environment, aiming to generate robust baseline schedules that will be as stable possible during execution. problem, are taken into account, and objective function is solution robustness maximization. As proved NP-hard in strong sense, develop a tabu search algorithm solve problem. After linearizing proposed model, use commercial mathematical programming solver...
Proactive project scheduling aims to generate robust baseline schedules that are protected against the potential schedule disruptions during execution. In this paper, we propose a new problem named proactive resource-constrained with activity split-ting and resource transfer times, try investigate trade-off between benefits of splitting drawbacks resulting more times. The proposed is formulated into an integer programming model considering constraints maximum allowed number minimum period...
Electrodes are critical to piezoelectric single crystal composites (PSCCs) as they directly determine the efficiency and reliability of devices. Currently, a comprehensive comparison major properties different electrodes on PSCCs, particularly their adhesive performance, is highly needed because cross-linked structure large surface-displacement fluctuations PSCCs likely cause peeling failure electrodes. Herein, we compared electronic conductivity performance for including magnetron...
WiFi positioning is the most promising means of indoor in future. However, localization techniques can’t meet requirements criminal investigation. Therefore, there a need to make research on passive location. This paper mainly researched location client based fingerprint. Based signal attenuation model, fingerprint algorithm and promiscuous mode, an improved technique introduced. First, we conducted in-depth for position RSSI (Received Signal Strength Indication). Then, propose solutions...
