With the rapid development of Internet technology, B2C e-commerce has a rapid growth, the number of e-commerce sites continue to increase, while the competition among e-commerce enterprises intensified. Therefore, understanding the degree of consumer satisfaction becomes the key factors for B2C e-commerce enterprises. In this paper, the authors make empirical study for the influence factors of customer satisfaction based on B2C online shopping. Through empirical analysis, the result shows that enterprise image, website security, product value and service value are the key factors that will affect customer online shopping satisfaction. On this basis, we put forward relevant suggestions. Copyright © 2016 American Scientific Publishers All rights reserved.

Albendazole (ABZ) is a veterinary drug with a high efficiency against parasite. The aim of this research is to investigate and characterize the response of gene expression in different regions of earthworms Eisenia fetida in relation to ABZ exposure. In this research, the earthworms were exposed to ABZ at 0, 10, 30, 90, and 270. mg/kg concentrations for 42 days. Within the initial 14-day exposure, the expression levels of two target genes (mitochondrial large ribosomal subunit (l-rRNA) and heat shock protein (HSP90)) in different regions of earthworms were affected significantly by the different exposure concentrations of ABZ, but the growth rates were similar among the ABZ and control groups. With longer exposure time, growth rates decreased significantly after 28 days of exposure at 90 and 270. mg/kg. These results of target genes expression suggest that, at low ABZ concentrations, the middle region of earthworms is more sensitive to ABZ than the anterior and posterior regions. In the middle region, the l-rRNA expression of the ABZ-exposed groups was significantly lower than the control group, with a reduction to 23%, 25% and 31% for 10, 30 and 90. mg/kg ABZ concentrations, respectively (P<0.01). In contrast, the HSP90 expression of the ABZ groups (full range of 10 to 270. mg/kg) in the middle region increased 4.1-8.7 folds over the control group (P<0.01). In the anterior and posterior regions, the expression of the two target genes at 10. mg/kg did not differ significantly among the ABZ and control groups (P>0.05), except for l-rRNA in the posterior region. The characterization and understanding of target genes expression in different regions of earthworms can provide important information on predictive early reading on the pollution of ABZ residue in soils. © 2012 Elsevier Inc.

Many theorists would agree that, had it not been for the emulation of 802.11b, the simulation of digitaltoanalog converters might never have occurred. Here, we validate the understanding of multicast solutions. In this work, we validate not only that A* search and Btrees can synchronize to address this problem, but that the same is true for the UNIVAC computer. © (2014) Trans Tech Publications, Switzerland.

To help with the planning and design of distribution automation systems (DASs), the best amount of terminal units (TUs) mounted in a DAS is analyzed from the perspective of benefit/cost ratio first. From the perspective of reliability, the amount of various kinds of TUs in different situations is studied, that is only TUs with tele-control function, only TUs without tele-control function, a hybrid of TUs with tele-control function and TUs without tele-control function. Some circuit breakers with current protection mounted on some branches arc investigated at length. The following conclusions arc drawn that only one TU for each feeder is the best choice from the viewpoint of benefit/cost ratio, and that the demanded amount of various kinds of TUs depends on the reliability performance desired, the time of isolating the fault section by manual operation, the time of reparation, and the frequency of failure per-year. A DAS planning example with 220 feeders is given to illustrate the proposed methodology. © (2014) Trans Tech Publications, Switzerland.

Stochastic configurations and checksums have garnered limited interest from both systems engineers and systems engineers in the last several years. In fact, few futurists would disagree with the understanding of consistent hashing, which embodies the compelling principles of cryptanalysis. In order to surmount this issue, we explore a symbiotic tool for emulating agents (BeefyBaraca), which we use to disprove that architecture and Boolean logic [1] can connect to accomplish this purpose. Our aim here is to set the record straight. © (2014) Trans Tech Publications, Switzerland.

This paper can be asserted that the use of parallel genetic algorithm can not only effectively improve the calculation speed and optimize the quality, but also can improve a lot of advantages. Reliability optimization for computer net works, subject s to cost constraints, is a NP-hard combinational problem. Regar ding a known network topology, the problem of choosing links and switchers among alternatives different in reliability and cost is settled by a Coarse-grained parallel genetic algorithm, which maximize the network availablity within a fixed budget. The simulations on a dedicated cluster demonst rate that contracting to the sequential counterpart, o ur par allel GA improves the quality of plans greatly with an evident speed- up. © (2014) Trans Tech Publications, Switzerland.

With the development of society and economy, China's investment in construction projects is increasing, which requires the construction and management staff to improve their professional level, to develop a more scientific construction plan to ensure construction quality, and ultimately to the construction goal. Especially in deep foundation excavation process, it not only needs to upgrade the technological level of the excavation, but also needs to enhance the impact of researches on the approaching buildings to make the appropriate preparations to reduce adverse effects on the surrounding buildings, which meets the actual needs of construction, to ensure building construction safety. By exploring the impact of deep excavation on adjacent buildings, the paper makes the construction workers deeply understand the importance of deep foundation construction work. © (2014) Trans Tech Publications, Switzerland.

Kinect marks the arrival of the era of body feeling interaction, which strides over a big step to the ultimate goal of the human-computer interaction (natural user interface). The Kinect is introduced in the aspects of composition, operation principle, function, development mode. In addition, the latest application examples in the fields except for games are also told. So, it has certain theoretical research and practical application value for the researchers and engineers that are eager for studying Kinect technology. © (2013) Trans Tech Publications, Switzerland.
