The human resources are the only ones resources able to produce and reproduce all the other resources available to a sports organization, although the material and financial ones are important. The jobs’ analysis is the process that determines the tasks, the activities specific to a position and the type of persons recommended for its occupation, involving a common effort by the specialist in human resources, hierarchical chief and employee, being necessary to provide us exact information regarding the job and to justify the staff decisions. The productivity in all sports organizations is influenced by how they interact and combine the human resources in order to use the other resources of the management system. Factors such as preparation, age, job experience and the level of formal education play a role in establishing the person compatibility with a certain organization. The process of assurance of human resources suitable for a sports structure is an engaging process and slightly subjective. In order to assure the human resources that cover both managerial positions, as well as the execution ones, the managers follow the next sequentially steps: recruitment; selection; training and improvement; evaluation. There is a reciprocal interdependence between the management and execution positions established by the nature of relations that exists between the decision centers of the sports organization and its effective centers.

Time is a focal point for historical research. Although existing Linked Open Data (LOD) resources hold time entities, they are often limited to modern period and year-month precision at most. Therefore, researchers are currently unable to execute co-reference resolution through entity linking to integrate different datasets which contain information on the day level or remote past. This paper aims to build an RDF model and lookup service for historical time at the lowest granularity level of a single day at a specific point in time, for the duration of 6000 years. The project, Linked Open Date Entities (LODE), generates stable URIs for over 2.2 million entities, which include essential information and links to other LOD resources. The value of date entities is discussed in a couple of use cases with existing datasets. LODE facilitates improved access and connectivity to unlock the potential for the data integration in interdisciplinary research.

This paper shows the extension of an entity model developed in cooperation with project partners by an “Organizational Entity” in order to detect potential weaknesses in IT security as well as to prove the standard conformity (IT security level according to IEC 62443) of the examined systems. This allows suitable security measures to be taken systematically and IT security to be optimized in the overall system. The first application of this progressive approach on a subsystem, the distillation, of the model factory ET of the University of Applied Sciences Magdeburg-Stendal is promising.

A brand-new smart wind turbine blade with magnetorheological fluid (MRF) sandwiched was proposed in the research. The three-dimension entity model of a 750 KW wind turbine blades was established through the use of UG software, and three kinds of MRF sandwich layouts were considered into the blade model, that is, at the blade tip, at the blade root and at the whole blade from the root till the tip. The MRF was simplified as Kelvin-Voigt model in order to implement the finite element analysis based on ANSYS software, so that the mode shapes of smart wind turbine blade were revealed under various conditions with three different layout forms of MRF sandwich wind turbine blades. Analysis results showed that the magnetic field would influence the mode shapes of the wind turbine blade with MRF sandwiched, especially the torsion vibration. When the MRF was inserted through the blade from the root till the tip, the blade would dramatically influence the torsion vibration, so that the torsion vibration, which originally would have happened at higher orders, would arise in advance. While the MRF was located at the root of wind turbine blade, the torsion vibration would be postponed to arise at the higher orders. Therefore, the MRF should be located at the blade root, instead of the middle and the tip of wind turbine blade. Smart sandwich wind turbine blade will provide a new way to the vibration control of wind turbine blade.

Accurate and fast indoor Location-Based Services (LBS) is very important for daily life and emergency response. Indoor map is the basis of indoor LBS. The model construction and data organization of indoor map are the key scientific problems that urgently need to be solved in the current indoor LBS application. In recent years, hybrid models have been used widely in the research of indoor map, because they can balance the limitations of single models. However, the current studies about hybrid model pay more attention to the model accuracy and modeling algorithm, while ignoring its relationship between positioning and navigation and its practicality in mobile indoor LBS applications. This paper addresses a new indoor map model, named Building Information Modeling based Positioning and Navigation (BIMPN), which is based on the entity model and the network model. The highlight of BIMPN is that it proposes a concept of Step Node (SN) to assist indoor positioning and navigation function. We developed the Mobile Indoor Positioning and Navigation System (MIPNS) to verify the practicability of BIMPN. Results indicate that the BIMPN can effectively organize the characteristics of indoor spaces and the building features, and assist indoor positioning and navigation. The BIMPN proposed in this paper can be used for the construction of indoor maps and it is suitable for mobile indoor positioning and navigation systems.

Implementing a flexible configuration of the QoS parameter in a distributed computing network has become a problem due to the weak scalability of current approaches. In an effort to solve this problem, an inner basic model of an intelligent agent (IA) is presented. The IA functionality was extended by introducing a primarily mobile agent. A QoS guarantee scheme was subsequently designed and implemented based on the model as well. By utilizing the proposed scheme, the IA can sense, predict and configure the data flow traffic. Since the communicating ability was considered and provided, the competition among different devices could be eliminated effectively and the global traffic can be optimized. The results of the simulations have shown that the proposed model can provide a QoS guarantee.

Integrated modelling has become an urgent issue of urban drainage and wastewater treatment planning. The scope of integrated modelling, system boundaries and disciplines to be involved are addressed in view of future developments and new paradigms in urban drainage, demanding the inclusion of the full urban water cycle. A system analysis is demonstrated to identify relevant sub-systems and components, processes and interactions within the urban water system. The permissibility to exclude subsystems or neglect interactions is evaluated. Integrated modelling of urban water system is characterised as an ambitious task in regard to system complexity, heterogeneous scales and interface problems. The methodical status quo is characterised in preliminary approaches towards integrated modelling. It is concluded that it does not seem promising to create and apply one entity model for the scope of integrated urban water modelling. Instead, the development of adequate and efficient IT frameworks is identified as the key issue of integrated modelling. Harmonising interfaces to facilitate the linking of existing models is presented as the objective of a European research project HarmonIT and the U.S. EPA Multimedia Integrated Modelling System project MIMS.

Evolution and customization of component-based systems require an explicit understanding of component inter-dependencies. Implicit assumptions, poor documentation and hidden dependencies turn even simple changes into challenges. The problem is exacerbated in XML-intensive projects due to the use of soft references and the lack of information hiding. We address this with dependency tracking interface types for models and metamodels. We provide automatic compatibility checks and a heuristic inference procedure for our interfaces, which allows easy and incremental adoption of our technique even in mature projects. We have implemented a prototype and applied it to two large cases: an enterprise resource planning system and a healthcare information system.

An analysis is made to find the transport properties of a free turbulent flow using an entity model previously shown to have good prediction capability for pipe flow. It is shown that the double structure of the turbulent eddies and the anisotropic shape of the larger eddies can be satisfactorily incorporated into the model without undue complexity. The analysis results in expressions for the various diffusivities in terms of properties of the turbulence. Predictions can be made for the diffusivity ratios and their dependence on molecular properties of the fluid determined. The results are shown to be in good agreement with the available experimental data.
