In real-world cargo transportation, there are charges associated with both the traveling distance and loading quantity. Cargo trucks must comply a mandatory lower carbon emissions policy: of large-volume truck/containers depend greatly on distance. To address this issue, instead assuming constant vehicle from one customer to another, variable should be used in optimizing routine, which is known as weighted routing problem (WVRP) model. The WVRP an NP-hard problem; thus, purpose paper develop...

A diblock copolymer, poly(methyl methacrylate)-b-polystyrene (PMMA-b-PS), was grafted onto the surface of nano-titania (nano-TiO2) successfully via reversible addition-fragmentation chain transfer (RAFT) polymerization. The TiO2 nanoparticles modified initially by attaching dithioester groups to using silane coupling agent 3-(chloropropyl)triethoxy and sodium ethyl xanthate. polymerization methyl methacrylate styrene were then initiated propagated on RAFT resulting composite characterized...

An equalizer is always adopted in an underwater acoustic communication system to reduce the intersymbol interference (ISI) due multipath effect. This paper introduces basic structure and principle of a blind at first. Then constant modulus algorithm (CMA) derived applied affected by channel severely. The simulation results show that CMA eliminates ISI significantly. valuable practically because training sequence unnecessary for it.

Abstract Robust and accurate state-of-health (SOH) estimation is significant for safe reliable operation of electric vehicles (EVs). In this paper, the robustness analysis a specific IC method based on probability density function investigated in depth. Four aging features frequently used by existing researches to estimate SOH are extracted from curve. The influence temperature current rate these four as battery ages analyzed detail. These features’ sensitiveness data length their appearance...

Models of two-stage and three-stage games are set up in this article according to the Hotelling linear model. In models, one-round pricing products concerning differentiated cost asymmetric information for duopoly enterprises is considered. The marketing strategy price competition product differentiation discussed. And it must result such a situation that both sides can obtain higher more profit Stackelberg equilibrium than Nash equilibrium. Moreover, under Bertrand-Stackelberg equilibrium,...

Underwater acoustic (UWA) communication is a cross subject of the technology and underwater signal processing technology, which very valuable in military civil applications. But multipath effect UWA channel leads to inter symbol interference (ISI) more than hundreds code intervals, so it necessary apply an equalizer eliminate ISI receiving unit. This paper proposes two new weight initialization strategies for least mean square (LMS) adaptive linear due bad performance with all zero...

In order to model emergency rescue location problem with uncertain time, an expected cost minimization is proposed under environment. For solving this model, we convert the its equivalent deterministic form. Finally, a numerical example has been presented illustrate model. The computational results which were solved by down mountain algorithm are provided demonstrate effectiveness of

The traveling salesman problem (TSP) is a well-known combinatorial optimization problem. While, in classical TSP and its variants, the priority of each city assumed as same. objective function neglects extra vehicle loading cost caused by practical factors when optimizing route. However, real-world, varies from one to another affects cost. Thus, route without considering effect different may be not reasonable enough lead sub-optimal solutions. In this paper, we investigate Weighted Traveling...

Endometrial cancer is the most prevalent form of gynecologic malignancy, with a significant surge in incidence among youngsters. Although advent immunotherapy era has profoundly improved patient outcomes, not all patients benefit from immunotherapy; some experience hyperprogression while on immunotherapy. Hence, there pressing need to further delineate distinct immune response profiles endometrial enhance prognosis prediction and facilitate immunotherapeutic responses. The ssGSEA method was...

In this letter, we propose a novel scheme to reduce the PAPR of OFDM signals. It combined channel estimation in system based on comb-type pilots and Flipping PTS algorithm. At sender insert comb pilot independently evenly into every partitioned sub-blocks after partition. The side information algorithm as one part frequency response is transmitted. We can achieve without SI. Simulation results show that performance new SI worse than with However, it reduced PAPR, increased data rate.

The purpose to improve the performance of network, thus ensure efficiency and safety management in airspace. objective minimize number radar decision variable site radar. Only one type considered. Firstly, without affect arrange them suitable position satisfying requirement complete coverage. For problem, regular hexagonal expansion algorithm tabu search proposed....

Two kinds of methods (the disperse degree test and the cross-sectional absolute deviation (CSAD)) are used in this paper to herding behavior when price Chinese stock market undulates violently. The different so that results not completely consistent. Because method, two different. It can be found from compare analyses examine very violent Herding Behavior only, but can't lighter intelligently. However, method CSAD, existence intelligently, result is even more rational. CSAD shows there exist...

Underwater acoustic wireless sensor network (UAWSN) is the result of global popularity networks which combines underwater communication, networks, modern signal processing, techniques and so on. Because particular characters UAWSN such as big transportation delay, limited node power supply, many mature WSN can't be implanted to directly. UW-CSMA/CA MAC protocol UW-AODV Routing are proposed in this paper underlie Data Link Layer Network stack UAWSN. Simulations experiments Qiandao Lake show...

Topology structure for UAWSN has to be of general characters WSN not only, but also consider the limited communication range and cell energy, effect single damaged whole network so on. This paper analyzes energy efficiency theoretically then presents simulation results square triangle topology structures with different scale. All these researches show that is greatly related structure. With increase scale (K) much wasted on relays which decrease efficiency. If fixed unchanged higher than triangle.
