Landslides susceptibility mapping in Guizhou province based on fuzzy theory

The purpose of this study was to assess the susceptibility of landslides around the area of Guizhou province based on fuzzy theory.In first instance, slope, elevation, lithology, proximity to tectonic lines, proximity to drainage and annual precipitation were taken as independent, causal factors in this study.A landslide hazard evaluation factor system was established by classifying these factors into more subclasses according to some rules.Secondly, a trapezoidal fuzzy number weighting(TFNW) approach was used to assess the importance of six causal factors to landslides in an ArcGIS environment.Thirdly, a landslide susceptibility map was created based on a weighted linear combination model.According to this susceptibility map, the study area was classified into four categories of landslide susceptibility:low, moderate, high and very high.Finally, in order to verify the results obtained, the susceptibility map and the landslide inventory map were combined in the GIS.In addition, the weighting procedure showed that TFNW is an efficient method for weighting causal landslide factors.

Fatigue Topology Optimization Design Based on Distortion Energy Theory and Independent Continuous Mapping Method

Fatigue failure is a common failure mode under the action of cyclic loads in engineering applications,which often occurs with no obvious signal.The maximum structural stress is far below the allowable stress when the structures are damaged.Aiming at the lightweight structure,fatigue topology optimization design is investigated to avoid the occurrence of fatigue failure in the structural conceptual design beforehand.Firstly,the fatigue life is expressed by topology variables and the fatigue life filter function.The continuum fatigue optimization model is established with the independent continuous mapping(ICM)method.Secondly,fatigue life constraints are transformed to distortion energy constraints explicitly by taking advantage of the distortion energy theory.Thirdly,the optimization formulation is solved by the dual sequence quadratic programming(DSQP).And the design scheme of lightweight structure considering the fatigue characteristics is obtained.Finally,numerical examples illustrate the practicality and effectiveness of the fatigue optimization method.This method further expands the theoretical application of the ICM method and provides a novel approach for the fatigue optimization problem.

Design and Production of a Patient Guide to Support Return to Work after Breast Cancer:An Application of Intervention Mapping

Aims.Return to work(RTW)after breast cancer is a complex process that questions the individual trajectories of patients and stakeholders.Program planning in this context requires relying on appropriate methods like Intervention Mapping(IM)which encompasses such complexity.The aim of the methodological study is to describe an application of IM for both the design and production of a patient guide supporting RTW after breast cancer.Procedure.According to IM,the guide was co-constructed with a Community Advisory Board(CAB)of stakeholders(patients/associations,health professionals,companies,institutions)after considering other options(interactive website,mobile application).The design was done with empirical and theoretical anchoring,guided here by an Ecosystem Process of Change model.A communication agency was chosen to produce the document.Pre-tests were conducted with a representative panel of the target audience to assess the different prototypes elaborated,using questionnaires and a focus group.Results.The final structure of the guide is presented with comments in order to concretely illustrate the management of IM steps 3 and 4.The final structure of the guide is presented,along with a description of its components that target women(according to Prochaska et Di Clemente’s stages of change)and their environment(by use of levers they may activate).The results of the pre-test led to the simplification of the guide and its structure.Conclusion.IM allows a rich integration of experiential knowledge in the planning of complex health and public health programs.The development of the guide has attempted to integrate its aspects,in particular to promote both its implementation and its effects.Reflections are brought about the realistic evaluation of such complex interventions.

Ontology mapping approach based on set & relation theory and OCL

An ontology mapping approach based on set & relation theory and OCL is introduced,then an ontology mapping meta-model is established which is composed of ontology related elements,mapping related elements and definition rule related elements.This ontology mapping meta-model can be regarded as a unified mechanism to realize different kinds of ontology mappings.The powerful computation capability of set and relation theory and the flexible expressive capability of OCL can be used in the computation of ontology mapping meta-model to realize the unified mapping among different ontology models.Based on the mapping meta-model,a general mapping management framework is developed to provide a common mapping storage mechanism,some mapping APIs and mapping rule APIs.

FIXED POINT INDEX THEORY FOR WEAKLY INWARD MAPPINGS

In this paper we define a fixed point index theory for locally Lip., completely continuous and weakly inward mappings defined on closed convex sets in general Banach spaces where no other artificial conditions are imposed. This makes ns to deal with these kinds of mappings more easily. As obvious applications, some results in [3],[5],[7],[9],[10] are deepened and extended.

DEGREE THEORY FOR MULTIVALUED (S) TYPE MAPPINGS AND FIXED POINT THEOREMS

The main purpose of this paper is devoted to generalizing the results of Browder[1,2]This paper consists of four parts. In the first part, we introduce the concepts of multivalued (S) and (S), type mappings and the concepts of the limits of multivalued (S) and (S) + type mappings. These kinds of mappings contain many monotone type mappings, such as maximal monotone mapping, bounded pseudo-monotone mapping and bounded generalized pseudo-monotone mapping, as its special cases. In the second part we define the pseudo-degree for (S) type mapping and the degree for (S)+ type mapping. These two kinds of degrees are all the generalizations of the degree defined by Browder[1,2] As applications, we utilize the degree theory presented in part 2 to study the existence of solutions for the multivalued operator equations (see part 3) and to obtain some new fixed point theorems in part 4.

RECENT PROGRESS OF NANO-MECHANICAL MAPPING

Nano-mechanical mapping by atomic force microscopy has been developed as an useful application to measure mechanical properties of soft materials at nanometer scale.To date,the Hertzian theory was used for analyzing force- distance curves as the simplest model among several contact mechanics between elastic bodies.However,the preexisting methods based on this theory do not consider the adhesive interaction in principle,which cannot be neglected in the ambient condition.A new analytical method was introduced...

Static Analysis of Anisotropic Doubly-Curved Shell Subjected to Concentrated Loads Employing Higher Order Layer-Wise Theories

In the presentmanuscript,a Layer-Wise(LW)generalizedmodel is proposed for the linear static analysis of doublycurved shells constrained with general boundary conditions under the influence of concentrated and surface loads.The unknown field variable is modelled employing polynomials of various orders,each of them defined within each layer of the structure.As a particular case of the LW model,an Equivalent Single Layer(ESL)formulation is derived too.Different approaches are outlined for the assessment of external forces,as well as for non-conventional constraints.The doubly-curved shell is composed by superimposed generally anisotropic laminae,each of them characterized by an arbitrary orientation.The fundamental governing equations are derived starting from an orthogonal set of principal coordinates.Furthermore,generalized blending functions account for the distortion of the physical domain.The implementation of the fundamental governing equations is performed bymeans of the Generalized Differential Quadrature(GDQ)method,whereas the numerical integrations are computed employing theGeneralized IntegralQuadrature(GIQ)method.In the post-processing phase,an effective procedure is adopted for the reconstruction of stress and strain through-the-thickness distributions based on the exact fulfillment of three-dimensional equilibrium equations.A series of systematic investigations are performed in which the static response of structures with various curvatures and lamination schemes,calculated by the present methodology,have been successfully compared to those ones obtained fromrefined finite element three-dimensional simulations.Even though the present LW approach accounts for a two-dimensional assessment of the structural problem,it is capable of well predicting the three-dimensional response of structures with different characteristics,taking into account a reduced computational cost and pretending to be a valid alternative to widespread numerical implementations.

A Map Coloring Method

Different vertices are colored in a plan. Adjacent vertices are colored dif-ferently from nonadjacent vertices, which are colored the same color. One color is used for a single point, two colors are used for points without a loop, and a maximum of four colors are used for points with a loop. A maximum of four colors are used to color all points. .

Almost Injective Mappings of Totally Bounded Metric Spaces into Finite Dimensional Euclidean Spaces

Let χ= be a metric space and let ε be a positive real number. Then a function f: X→Y is defined to be an ε-map if and only if for all y∈Y, the diameter of f-1(y)?is at most ε. In Theorem 10 we will give a new proof for the following well known fact: if χ is totally bounded, then for all ε there exists a finite number n and a continuous ε-map fε: X→Rn (here Rn is the usual n-dimensional Euclidean space endowed with the Euclidean metric). If ε is “small”, then fε is “almost injective”;and still exists even if χ has infinite covering dimension (in this case, n depends on ε, of course). Contrary to the known proofs, our proof technique is effective in the sense, that it allows establishing estimations for n in terms of ε and structural properties of χ.

Mapping Folklore Concepts in Bilingual Processing:Cognitive Analysis

The present study applies Dr.He Yuanjian's CMT(Conceptual Mapping Theory) to focus on the strategy use of translating Chinese folklore concepts in Hong Lou Meng(i.e.indigenous concepts related to etiquettes and customs) by Yang Xianyi and his wife Gladys Yang on the observations of the translators'strategies and the distributional tendencies of translation strategies so as to testify CMT on empirical grounds.Whether it holds true that the preservation of the alien source concepts through translation depends on how successfully they are mapped into the target conceptual system leads to the attempts to study on the distributional tendency of translation strategies of translation tasks,especially,of translating folkloric concepts in this paper.As a result,the tentative outcome of the data observed supports that the concept-mediation theoretic approach to translation process seems able to account for how cognitive constraints affect the production of mapping the unshared concepts.

战略变革情境中的组织多层级悖论网构建--基于经典扎根理论的研究

战略变革情境中充斥着各种悖论问题,这些悖论问题相互交错、影响、撬动、传递,形成复杂、混沌的战略变革情境特征,增加了决策者剥离情境探寻制定新战略根源性依据的难度,使得归纳各悖论之间链接规律并系统性刻画战略变革情境成为迫切需求.加上悖论在非变革情境下往往呈隐匿状态,不易被识别,而在战略变革情境中呈凸显状态,容易被识别,因此战略变革情境为系统探究悖论及相互链接关系提供了可能.本研究以十家企业的战略变革数据为样本,采用经典扎根理论和认知地图组成的混合研究方法,从多层级悖论视角分析战略变革情境中的悖论问题,构建组织多层级悖论网模型.研究发现:1)战略变革情境中存在“利益-责任”等18个悖论类型,归属于执行悖论等6种悖论类别,符合“政策导向-需求-目标-方向-价值观-过程”的划分逻辑;2)悖论纵向分布于组织个体层、运营层、战略层、制度层,横向跨越规制、运营、研发、生产、市场五个职能部门,纵横交错,构成组织多层级悖论网的位置形态;3)悖论类型内部由构成悖论四个基本条件的因果或顺次关系构成,同一层级悖论类型之间存在“同层链状顺序”和“同层嵌套”两种关系,跨层级悖论类型之间存在“跨层链状顺序”、“跨层链状共存”和“跨层嵌套”三种关系,构成组织多层级悖论网的关系形态;4)整合组织多层级悖论网的位置形态和关系形态构建组织多层级悖论网模型,系统展示战略变革情境中由悖论的关系和位置构成的复杂状态,表明不同悖论类型之间普遍存在引发性和传递性特征.本研究基于多层级悖论视角,将复杂、混沌的战略变革情境具体化清晰化,为决策者正确认知战略变革情境,准确把握组织困境产生的根源,并做出有效战略决策提供理论参考.
