Hung-Yuan Chen
Art and Design Review (ADR) , 2017, DOI: 10.4236/adr.2017.51002
Abstract: With the popularization of internet shopping, visualization of goods package has become an important factor in communicating goods characteristics and plays a critical role in influencing consumers’ purchase decision. This phenomenon is particularly apparent in the case of mature consumer goods such as perfume products, chocolate, daily commodity, and so on. To construct a decision support model for assisting package designers to create a satisfying product package based on consumers’ affective responses, a series of visual experiment evaluation for perfume bottle package is conducted in the current study. The fuzzy analytic hierarchy process-based approach is proposed to construct the decision support model for perfume bottle visual design. In the current study, the feasibility of constructing model based on the fuzzy analytic hierarchy process approach is demonstrated and the resulting model can provide perfume package designers with an understanding of developing a new design alternative in the conceptual design stage.

Abstract: We genotyped 10 single nucleotide polymorphisms and one microsatellite spanning 34 kb across the SLC2A10 gene in a prospective cohort of 372 diabetic patients. Their association with the development of peripheral arterial disease (PAD) in type 2 diabetic patients was analyzed.At baseline, several common SNPs of SLC2A10 gene were associated with PAD in type 2 diabetic patients. A common haplotype was associated with higher risk of PAD in type 2 diabetic patients (haplotype frequency: 6.3%, P = 0.03; odds ratio [OR]: 14.5; 95% confidence interval [CI]: 1.3- 160.7) at baseline. Over an average follow-up period of 5.7 years, carriers with the risk-conferring haplotype were more likely to develop PAD (P = 0.007; hazard ratio: 6.78; 95% CI: 1.66- 27.6) than were non-carriers. These associations remained significant after adjustment for other risk factors of PAD.Our data demonstrate that genetic polymorphism of the SLC2A10 gene is an independent risk factor for PAD in type 2 diabetes.Peripheral arterial disease (PAD), defined as lower extremity arterial atherosclerosis, is one of most common diseases of the arteries and is a major complication of type 2 diabetes [1]. Conventional cardiovascular risk factors such as aging, smoking, hyperglycemia, hypertension and dyslipidemia have been shown to be associated with PAD [1]. However, the increased risk for atherosclerotic diseases in diabetic patients can be only partially explained by the conventional risk factors [2]. In fact, a high heritability for ankle-brachial blood pressure index (ABI), an index of PAD, has been obtained in Twin studies in Caucasians [3], indicating that additional genetic factors might be involved in the pathogenesis of PAD. In this respect, the search for genetic causes of PAD remains limited [4].Recently, a genetic form of arterial tortuosity syndrome (ATS; OMIM 208050) was reported to be caused by loss-of-function mutations in the SLC2A10 gene encoding the facilitative glucose transporter GLUT10.

Abstract: It is shown that the modified Schr?dinger equation proposed by Janossy cannot describe the behavior of the electron correctly. However, it is further shown that the equation can be regarded as a model of a possible phenomenalogical theory of nuclei or as a model of a possible theory of elementary particles. The quantization of the equation is discussed.

Abstract: 最近田渠提出了一个简单的核子电荷分布的模型。在一方面,这一模型准确地解释了中子的磁矩和质子的磁矩数值间的比。在另一方面,这一模型具有严重的理论上的困难和应用上的局限性。目前的场论还没有能力补救这一模型的这些缺点。 远在1925年,当乌伦贝克和高特斯密脱二氏提出电子具有自旋和磁矩的假设的时候,为了解释电子的回转磁比率,他们便为电子的结构提出了类似的模型。他们假

Abstract: The effect of the anomalous magnetic moment of the nucleon on the value of the internal conversion coefficient is investigated.The parts played by the sealer and tho longitudinal photons in the process of the internal conversion are first discussed. The retarded interaction between the charged particles with anomalous magnetic moment is derived by the correspondence method. The results obtained is then verified by the quantum electrodynamical treatment. The retarded interaction thus obtained is then applied to the calculation of the internal conversion coefficient. It turns out, that the anomalous magnetic moment of the nucleon has negligible influence upon the coefficient of the magnetic conversion and the coefficient of the electric conversion induced by the proton transition. However, the anomalous magnetic moment of the nucleon does cause considerable modification of the coefficient of the electric conversion induced by tho neutron transition, contrary io the conclusion arrived a,t by various authors. The problem of the gauge transformation is discussed and the errors contained in the treatment given by these authors are pointed out.

A Photovoltaic Power System Using a High Step-up Converter for DC Load Applications
Sheng-Yu Tseng,Hung-Yuan Wang
Energies , 2013, DOI: 10.3390/en6021068
Abstract: This paper presents a power system using a high step-up converter for dc load applications. The high step-up converter adopts a boost converter with interleaved mode and a coupled inductor to raise its powering ability and increase its step-up voltage ratio, respectively. In order to increase conversion efficiency, an active clamp circuit is introduced into the proposed one to provide soft-switching features to reduce switching losses. Moreover, switches in the converter and active clamp circuit are integrated with a synchronous switching technique to reduce circuit complexity and component counts, resulting in a lower cost and smaller volume. A perturb and observe method is adopted to extract the maximum power from photovoltaic (PV) arrays. Furthermore, a microchip associated with PWM IC is used to implement maximum power point tracking operation, voltage regulation and power management. Finally, a prototype PV power system with 400 V/6 A has been implemented for verifying the feasibility of the proposed PV power system. It is shown to be suitable for PV energy conversion applications when the duty ratios of switches in the dc/dc converter are less than 0.5.
A Novel Call Admission Control Policy Using Mobility Prediction and Throttle Mechanism for Supporting QoS in Wireless Cellular Networks

Journal of Control Science and Engineering , 2011, DOI: 10.1155/2011/190643
Abstract: The decision of call admission becomes an important work owing to the scarce wireless spectrum for wireless cellular networks. If there exists adequate information for call admission control (CAC) schemes, the terms of quality of service (QoS), such as call dropping probability (CDP), call blocking probability (CBP), and system utilization, will be kept in a certain acceptable level. Therefore, a prediction system which can predict most information, such as system utilization and CDP, in advance with a novel data mining technique and a distributed CAC scheme is presented in this paper. Based on the prediction results and the bandwidth consumption of adjacent cells, the proposed CAC scheme is able to decide to admit a new call. The throttle flag that can indicate the usage of current cell is proposed to prevent the newly admitted call request from being blocked in adjacent cells if handoff is needed. The simulation results show that the proposed CAC scheme can maintain the CDP below a predefined threshold, and the CBP is also lower than the cluster prediction and traditional guard channel policies. 1. Introduction With the evolution of mobile communication, the types of services have been evolved from voice service to multimedia [1, 2]. As a large number of bandwidths are required for multimedia services for wireless cellular networks, the most important issue is to support QoS for subscribers. Although there has been a rapid development in wireless cellular communications, the QoS guarantee remains one of the most challenging issues [3, 4]. One of the key elements for providing QoS guarantees is an effective CAC policy, which not only has to ensure that the network meets the QoS of the newly arriving calls, but also guarantees that the QoS of the existing calls will not be degraded. Because of the increase in mobile velocity and limited radio spectra, it is difficult to allocate suitable bandwidths for mobiles before handoff to the appropriate cell for a bandwidth reservation and CAC policy. The variable user mobility has made it more complex to predict the appropriate cell for handoff. The prior researches [5–8] have showed the impact of mobility on wireless cellular networks and provided a modeling method for configuring wireless cellular networks to study the dynamics of mobility. However, the CBP should be also mentioned simultaneously while the QoS is considered for an effective CAC policy. There have been so many studies, such as [4, 9, 10] which had focused on the issues of QoS guarantee. Furthermore, the effective user mobility and resource
