Abstract: This paper aimed at the rich hot spring resources and relevant industries were regarded as one major domain worth further developing in Taiwan. But under the current situation adversely affected by economic downturn and diverse customers’ need, how to survival in a market with extremely intense competition, while maintaining high profits, high lodging rate and high visiting rate, are the most essential challenge facing numerous hot spring hotels operators and other relevant trades. Apart from collecting related literature of hot spring hotel and conducting in-depth analyses and induction, this study employs Delphi Method for expert interview. The decision-making model of customers’ choosing hot spring hotel is established, the 6 major criteria are further divided into 19 indicators, for constructing the integral valuation model of this study, followed by issuing questionnaire of expert weigh of Analytic Hierarchy Process (AHP), with the aim to integrate and calculate the important relations between criteria and indicators. The results of this study are expected to be used by relevant trades as reference for future operation.

Abstract: Unidirectional conduction block of cardiac excitation wave is one of the necessary conditions leading to initiation of reentrant arrhythmia. Temporal vulnerable window (VW_time) is an important measure for arrhythmia vulnerability. In this study, we examine theoretically how low extracellular K concentration ([K]_o) control the VW_time by a single premature extrasystole. A numerical modified LR91 one dimensional heterogeneous ventricular model is used to quantitatively investigate the relation of low [K]_o with conduction velocity (CV), VW_time, and electrical dynamic factor CV restitution. Morever, we characterize the distribution of Na channel conductance (g_Na) and gating factors of premature beat applied at different time of the VW_time with different [K]_o. The results show that lowering [K]_o enlarge the VW_time magnitude gradually. The CV of S1 beat slows down with the [K]_o in a reverse-[K]_o dependent manner. Low [K]_o promote the recovery of maximum Na conductance (G_Na) from inactivation. However, decreasing [K]_o can increase heterogeneity of g_Na along the cable, and modulate CV restitution curve, which induce larger transmural dispersion of refratoriness for the premature beat and enlarge the VW_time.

Abstract: With the development of organ building in universities, we’ll find the incentive is not sufficient. Though there are many kinds of forms, effects turn out different. This article, based on ISO9000 quality management system, probes into whether the criteria make management more applicable. So it requires a long-term efficient system to satisfy people

Abstract: Built-in Test (BIT) technique is a important equipment in complex electronic system. In this paper, the CAN bus based on intelligent built-in test technique in complex electronic system was presented to make use of the advantages of CAN bus to solve the problems of communication and reliability of the distributed intelligent BIT system. This paper elaborates the structure of intelligent BIT system and the fault-detection technique, and the nodes in intelligent BIT system are equipped with the CAN bus interface. It also describes the software and hardware design of intelligent BIT node. The high-speed communication and reliability of CAN bus facilitate the communication and timely disposal of the testing signal and the intelligent BIT design. Experiments and practical applications approved that this technical method was feasible and effective.

Abstract: CBR(Case-based reasoning)is an important research direction of artificial intelligence field,which start a new way for it. The mine hoist spindle is the most critical equipment to hoisting equipment.It is the main part of the machine which relates to the upgrading of equipment life.With the platform of Visual C++,we analysised the design methods of the mine hoist spindle based on CBR in this experiment.It will combine computer-aided design technology with artificial intelligence factors.

Abstract: Characters on license plate, which is obscured by water or mist, is hard to be recognized through classical license plate recognition technology. In order to get higher recognition rate of blurred character in practical license plate recognition system, an approach to separate characters from a blurred image of vehicle license plate is proposed in this paper. At first, the upper, lower, left and right boundaries of blurred character are assumed to be foreground sample; the broken boundary of character is considered as background sample. At the position of background white scribbles are drawn; in contrast, midpoints of the lines along foreground are painted with black scribbles. Then a scribble image is generated automatically. Furthermore, closed form solution to natural image matting is adopted to obtain the background that is uncovered license plate according to the scribble image. The experiments show that the new algorithm is applicable and helpful to get higher recognition rate of blurred license plate.

Abstract: With the improving of reservoir development level, reservoir geologic research urgently need some new and practical technical methods to describe reservoir more accurately and meticulous. The three-dimensional geological modeling exactly is one of the main aspects to resolve the problem. Take the Chang109 block of Changchunling oilfield for an example. Using Petrel, which is multi-disciplinary and synthetical software for researching reservoir and to establish a 3D geological model as the outstanding characteristic, to build the reservoir model displaying geological information system. That, including the structure model, the sedimentary facies model and the property model, will provide reliable basis potential finding and well placement.

Abstract: The particle filter (PF) algorithm provides an effective solution to the non-linear and non-Gaussian filtering problem. However, when the motion noises or observation noises are strong, the degenerate phenomena will occur, which leads to poor estimation. In this paper, we propose a modified particle filter (MPF) algorithm for improving the estimated precision through a particle optimization method. After calculating the coarse estimation with the traditional PF, we optimize the particles according to their weights and relative positions, then, move the particles toward the optimal probability distribution. The state estimation and target tracking experiments demonstrate the outstanding performance of the proposed algorithm.

Abstract: The physical gap is a kind of security protection products that can guarantee information security by disconnecting the connections between the intranet and the extranet. It’s commonly deployed between the secret-related network and the Internet to protect information security. Because of the market demand, a lot of gaps are produced, but without strict quality control. However, the importance of the physical gap’s quality and stability continue to grow with the intensification of competition in the marketplace. In addition physical gaps may exhibit failures or degrade only under certain stress conditions in most cases. So it’s necessary to conduct test especially stress test for the physical gap. In fact, the most effective way to qualify a physical gap and to assure whether a physical gap meets its stability and quality goals is through stress testing. In this paper, we discuss why and how to qualify a physical gap through stress testing. We also presented a stress testing case designed for the physical gap to show how to conduct stress testing and analyze the testing result. To the best of our knowledge, there is a lack of research about conducting stress test for physical gap to date.
