Business domain oriented AI planning for web service composition

In order to improve the effectiveness of the artificial intelligence （AI） planning based web service composition problem, a business domain oriented AI planning algorithm for web service composition is introduced. The algorithm uses the proposed business relation model to minimize the searching space and uses the proposed goal distance as a heuristic rule. Compared with other algorithms tackling web service composition such as AI planning, the proposed algorithm focuses not only on how to convert the web service composition problem to the AI planning problem, but also exerts its effort on how to apply the business feature of web service composition into planning in order to improve the effectiveness. The experiment shows the better performance of the proposed algorithm.

Edge detection in the potential field using the correlation coefficients of multidirectional standard deviations

Most edge-detection methods rely on calculating gradient derivatives of the potential field, a process that is easily affected by noise and is therefore of low stability. We propose a new edge-detection method named correlation coefficient of multidirectional standard deviations（CCMS） that is solely based on statistics. First, we prove the reliability of the proposed method using a single model and then a combination of models. The proposed method is evaluated by comparing the results with those obtained by other edge-detection methods. The CCMS method offers outstanding recognition, retains the sharpness of details, and has low sensitivity to noise. We also applied the CCMS method to Bouguer anomaly data of a potash deposit in Laos. The applicability of the CCMS method is shown by comparing the inferred tectonic framework to that inferred from remote sensing（RS） data.

QoS-oriented service composition based on mapping relation tree

Service composition is a hot and active research area in service-oriented computing which has gained great momentum. An quality of service (QoS) oriented and tree-based approach was proposed to implement service composition efficiently. Firstly, service descriptions were transformed to mapping relations which denote the association between input and output concepts. Then, the service composition problems were resolved by building mapping relation tree dynamically based on the divide and conquer method, and all mapping relation trees were combined without redundant branch to obtain the composition scheme. Finally, the optimal composition scheme was chosen based on quality of service attributes including the preference of service request. Experiment results illustrate that this method can improve the composition efficiency and reduce the searching time by increasing the number of services in repository.

A Construction of Relative Difference Set

Logistics Management based on Supply Chain Management

Logistics is an important part of the supply chain and connect all aspects of the supply chain throughout it, which has become business cooperation ties. In the process of developing supply chain logistics strategy, generally require attention to the following questions： To segment customers, we should determine the appropriate level of customer service, such as order cycle, inventory levels and other modes of transport for different types of clients; Group products according to sales on them, we can take different strategies for each category of products. Order entry, order execution and delivery job processing accounted for a large proportion of logistics activities, which requires technology and management to make the entire processes of supply chain logistics more efficient, especially for the interface area between members of enterprises. We can eliminate redundant work by integrating flow, improve logistics efficiency.

Analyzing the Relationships Between Factors Affecting Adolescents＇ Happiness in OECD Countries

The aim of this study is to investigate the causal relationships between key factors relating to education that affect the happiness of adolescents, and to put forward policy suggestions wherewith 20 OECD countries may raise their levels of adolescent happiness. The HBSC score of adolescents from 20 OECD countries was selected as an indicator for happiness, and a number of independent variables such as per capita GDP and per capita educational expenditure were included in the analysis. A structural equation model was employed for the analysis. The research results show that the variables that directly affected happiness were per capita educational expenditure, educational decentralization level, number of students per teacher, and others. Of these, per capita educational expenditure had the greatest influence. Of the paths to adolescent happiness, those that contained a significant indirect effect were ＂per capita GDP → per capita educational expenditure → happiness＂ and ＂educational decentralization → number of students per teacher → happiness＂, which were significant at the level ofp 〈 0.05. Compiling the paths toward adolescent happiness focusing on the significance of these direct and indirect effects shows that the ＂per capita GDP →per capita educational expenditure → happiness＂ path has the greatest effect.

A Study of the Link Between the Tourism Industry and the GDP in the ECO Countries

The present study aims at exploring the causal relationship between tourism industry and GDP in the economic cooperation organization （ECO） countries for the period of 2000-2010. To this end, the causal relationship between the two variables was examined using panel data and Granger standard causality test. The results demonstrate a unidirectional causality from GDP to the number of tourists coming to the ECO countries, it is also concluded that a rise in the country＇s GDP provides necessary conditions for investment on all sectors of the economy including the tourism sector. In such conditions, if the country＇s economic priorities comprise tourism development, then tourists will start visiting the country and the industry will flourish. Thus, policy-makers should focus on the increasing GDP if they want to increase the tourists＇ influx.

Exercise is recreation not medicine

Purpose： This paper responds to the question, is exercise medicine？ It does so using a qualitative case study that proposes that exercise is recreation. The study （1） describes and reflects upon an exercise is recreation metaphor, （2） establishes the principles and processes used to develop a sport park within which exercise is recreation, and （3） presents a comparative analysis of the exercise is recreation approach with a UK quality framework for ＂exercise referrals＂.

Creep and Shrinkage Effects on the Bond-Slip Characteristics and Ultimate Strength of Composite Slabs

Composite one-way concrete slabs with profiled steel sheeting as permanent formwork are commonly used in the construction industry. The steel sheeting supports the wet concrete of a cast-in-situ reinforced or post-tensioned concrete slab and, after the concrete sets, acts as external reinforcement. In this type of slab, longitudinal shear failure between the concrete and the steel sheeting is the most common type of failure at the ultimate load stage. Design codes require the experimental evaluation of the longitudinal shear capacity of each type of steel decking using full-scale tests. This paper presents the results of the short-term testing up to failure of two types of profiled steel decking that are commonly used in the construction industry in Australia. Fourteen full-scale, simply-supported slabs were tested in four-point bending with shear spans of either span/4 or span/6. Four slabs were tested at age of 28 days and the other 10 slabs were subjected to drying shrinkage and various levels of sustained loads for a period of at least 6 months prior to testing to failure. The effects of creep and drying shrinkage on the load carrying capacity and deformation of the slabs at ultimate loads are presented and discussed. The bond-slip relationship of each slab is determined from the test data and the values of maximum longitudinal shear stress calculated using different methods are described and compared.

Bivariate Gonarov polynomials and integer sequences

Univariate Gonarov polynomials arose from the Goncarov interpolation problem in numerical analysis.They provide a natural basis of polynomials for working with u-parking functions,which are integer sequences whose order statistics are bounded by a given sequence u.In this paper,we study multivariate Goncarov polynomials,which form a basis of solutions for multivariate Goncarov interpolation problem.We present algebraic and analytic properties of multivariate Gonarov polynomials and establish a combinatorial relation with integer sequences.Explicitly,we prove that multivariate Goncarov polynomials enumerate k-tuples of integers sequences whose order statistics are bounded by certain weights along lattice paths in Nk.It leads to a higher-dimensional generalization of parking functions,for which many enumerative results can be derived from the theory of multivariate Goncarov polynomials.

A general thermodynamic analysis and treatment of phases and components in the analysis of phase assemblages in multicomponent systems

Systematic thermodynamic analysis reveals that an essential condition for the thermodynamically valid chemographic projec-tions proposed by Greenwood is completely excessive.In other words,the phases or components from which the projection is made need not be pure,nor have their chemical potentials fixed over the whole chemographic diagram.To facilitate the analy-sis of phase assemblages in multicomponent systems,all phases and components in the system are divided into internal and external ones in terms of their thermodynamic features and roles,where the external phases are those common to all assem-blages in the system,and the external components include excess components and the components whose chemical potentials(or relevant intensive properties of components) are used to define the thermodynamic conditions of the system.This general classification overcomes the difficulties and defects in the previous classifications,and is easier to use than the previous ones.According to the above classification,the phase rule is transformed into a new form.This leads to two findings:(1) the degree of freedom of the system under the given conditions is only determined by the internal components and phases;(2) different external phases can be identified conveniently according to the conditions of the system before knowing the real phase rela-tions.Based on the above results,a simple but general approach is proposed for the treatment of phases and components:all external phases and components can be eliminated from the system without affecting the phase relations,where the external components can be eliminated by appropriate chemographic projections.The projections have no restriction on the states of the phases or the chemical potentials of components from which the projections are made.The present work can give a unified ex-planation of the previous treatments of phases and components in the analysis of phase assemblages under various specific conditions.It helps to avoid potential misunderstandings or errors in the topological analysis of phase relations.

Use of compositional and combinatorial nanomaterial libraries for biological studies

Abstract The rapid development and production of nanomaterials has created some concerns about their potential hazard on the environment, human health and safety. However, since the list of materials that may gen- erate such concerns is very long, it is impossible to test them all. It is therefore usually recommended to use some small compositional nanomaterial libraries to perform ini- tial toxicity screening, based on which combinatorial libraries are then introduced for more in-depth studies. All nanomaterials in the compositional and combinatorial libraries must be rigorously characterized before any bio- logical studies. In this review, several major categories of physicochemical properties that must be characterized are discussed, along with different analytical techniques that are commonly used. Some case studies from the University of California Center for Environmental Implications of Nanotechnology are also chosen to demonstrate the effec- tive use of compositional and combinatorial nanomaterials libraries to identify the role of some key physicochemical properties and to establish true quantitative structure-ac- tivity relationships. Examples on how to use the knowledge generated from those studies to design safer nanomaterials for improved biological applications are also presented.
