Exchange formats to interoberabilty support of the consolidated cadastre of public infrastructure information system

In a broad sense the consolidated cadastre of public infrastructure (ZKGJI) represents an environment in which the owners of data and users of the data can access or forward the data in ZKGJI on the basis of certain procedures. In a broad sense, the cadastre is not only a technical solution, a database or an application but is a whole organizational model of which the purpose is to ensure conditions for a successful supervision and forwarding of data about ZKGJI objects. The assignment considers mostly forwarding the data and problems which we encounter in web services. The results of the assignment are in the interoperability of the data, the advantages of the GML and its mechanism for data interoperability. The assignment represents the proposition of how to protect infrastructure against damages (that had developed on cases of good practice abroad); it also assigns the propositions for an improvement of the system, and finally, through empirical part of compressing it proposes the best possible solution of compressing the GML files whilst transferring to the user. Compressing is extremely important for a successful web interoperable GIS database and mostly for a quick transfer of the demanded data. A simple GML- based database is made as an example to demonstrate the interoperability of GML databases. As an extra, we tested and showed the results of transferring the GML into KML format with a help of XSLT; and the employability of a chosen transferring format in web GIS applications such as Google Earth and Geopedia

Melting of Colloidal Molecular Crystals on Triangular Lattices

The phase behavior of a two-dimensional colloidal system subject to a commensurate triangular potential is investigated. We consider the integer number of colloids in each potential minimum as rigid composite objects with effective discrete degrees of freedom. It is shown that there is a rich variety of phases including ``herring bone'' and ``Japanese 6 in 1'' phases. The ensuing phase diagram and phase transitions are analyzed analytically within variational mean-field theory and supplemented by Monte Carlo simulations. Consequences for experiments are discussed.Comment: 10 pages, 4 figure

Protection and Conservation of the Value of Public Infrastructure\ud \ud

This paper discusses the system of public infrastructure protection on the systemic and implementation levels, and public infrastructure as a part of the local community assets. In this regard, special attention is paid to the present position and particular role of the cadastre of public infrastructure in ensuring the protection of public infrastructure, real depreciation accounting and the establishment of new relationships between local community and utility companies

The Influence of the Cost Reduction Directive on the Broadband Roll

This paper presents a view of network roll out to enable digitalization and economic growth. The policy overview and analyses of the alternative connections among the network points provides us with the same picture, i.e., the market is competitive, but also gives us the potential to roll out high-speed networks with lower costs and in shorter time periods. As the policy and real-data analyses suggest, the inclusive cooperation of the stakeholders and the empowerment of the relevant bodies are essential to ensure that the proposed system will work. Connectivity should lose the label of a development inhibitor and become a key factor in the consciousness of all the sectors

Computer simulation of bistable switching in a nematic device containing pear-shaped particles

We study the microscopic basis of bistable switching of a confined liquid crystal via Monte Carlo simulations of hard pear-shaped particles. Using both dielectric and dipolar field couplings to this intrinsically flexoelectric fluid, it is shown that pulsed fields of opposing polarity can be used to switch between the vertical and hybrid aligned states. Further, it is shown that the field-susceptibility of the surface polarisation, rather than the bulk flexoelectricity, is the main driver of this switching behaviour.</p

Spin models for orientational ordering of colloidal molecular crystals

Two-dimensional colloidal suspensions exposed to periodic external fields exhibit a variety of molecular crystalline phases. There two or more colloids assemble at lattice sites of potential minima to build new structural entities, referred to as molecules. Using the strength of the potential and the filling fraction as control parameter, phase transition to unconventional orientationally ordered states can be induced. We introduce an approach that focuses at the discrete set of orientational states relevant for the phase ordering. The orientationally ordered states are mapped to classical spin systems. We construct effective hamiltonians for dimeric and trimeric molecules on triangular lattices suitable for a statistical mechanics discussion. A mean-field analysis produces a rich phase behavior which is substantiated by Monte Carlo simulations.Comment: 19 pages, 21 figures; misplacement of Fig.3 fixe

Orientational transitions in a nematic confined by competing surfaces

The effect of confinement on the orientational structure of a nematic liquid crystal model has been investigated by using a version of density-functional theory (DFT). We have focused on the case of a nematic confined by opposing flat surfaces, in slab geometry (slit pore), which favor planar molecular alignment (parallel to the surface) and homeotropic alignment (perpendicular to the surface), respectively. The spatial dependence of the tilt angle of the director with respect to the surface normal has been studied, as well as the tensorial order parameter describing the molecular order around the director. For a pore of given width, we find that, for weak surface fields, the alignment of the nematic director is perpendicular to the surface in a region next to the surface favoring homeotropic alignment, and parallel along the rest of the pore, with a interface separating these regions (S phase). For strong surface fields, the director is distorted uniformly, the tilt angle exhibiting a linear dependence with the distance normal to the surface (L phase). Our calculations reveal the existence of a first-order transition between the two director configurations, which is driven by changes in the surface field strength, and also by changes in the pore width. In the latter case the transition occurs, for a given surface field, between the S phase for narrow pores and the L phase for wider pores. A link between the L-S transition and the anchoring transition observed for the semi-infinite case is proposed. We also provide calculations with a phenomenological approach that yields the same main result that DFT in the scale length where this is valid.Comment: submitted to PR

Thermomagnetic and magnetocaloric properties of metamagnetic Ni-Mn-In-Co Heusler alloy in magnetic fields up to 140 kOe

High cooling power of magnetocaloric refrigeration can be achieved only at large amounts of heat, which can be transferred in one cycle from cold end hot end at quasi-isothermal conditions. The simple and robust experimental method of direct measuring of the transferred heat of materials with magnetocaloric effect (MCE) in thermal contact with massive copper block with definite heat capacity in quasi-isothermal regime was proposed. The vacuum calorimeter for the specific transferred heat ∆Q and adiabatic temperature change ∆T measurements of MCE materials in the fields of Bitter coil magnet up to H = 140 kOe was designed and tested on samples of Ni43Mn37.9In12.1Co7 Heusler alloy with inverse MCE in the vicinity of meta-magnetostructural phase transition (PT). It was found, that the magnetic field H = 80 kOe produces complete PT from martensite to austenite with ∆Q = - 1600 J/kg at initial temperature 273 K
