Full textAbstract:
The modelling of uncoupled fluid flow and heat transfer problems of a district heating network using the finite element method (FEM) is presented. Since the standard thermo-hydraulic pipe elements cannot be directly used for modelling insulation, the main attention was paid to discretisation of multilayered structure of pipes and surrounding by one-dimensional thermal elements. In addition, validity of the finite element method was verified numerically by solving fluid flow and heat transfer problems in district heating pipelines. Verification analysis involves standard single pipe problems and simulation of fragment of district heating in Vilnius. Pressure and temperature results obtained by finite element method are compared with those by other approaches.

Full textAbstract:
District of Sijuk located in Belitung Island is rich with non-lead mineral content. As the part of Southeast Asia’s Lead Belt, the presence of Apatite-Ilmenite Rare Earth Element formed by the region’s geological condition is very likely. However, there has not been any activity to map and identify the apatite-ilmenite distribution in this region. Therefore, the objective of this study was to map the mineralized apatite-ilmenite in Sijuk District. Using remote sensing technology, Landsat 8 OLI were utilized to map the distribution of mineralized apatite-ilmenite rare earth element. Alteration mineral carrier, geological structure, and lithology data were all used as variables. Landsat-8 was pre-processed using band ratio and Directed Principal Component Analysis (DPCA) method for gaining alteration variable. The fuzzy logic method was then deployed for integrating all data. The result of this research showed the potential distribution of mineralized apatite-ilmenite with a total area of 1,617 ha. The most prioritized areas for apatite-ilmenite mineral exploitation are located in Air Seruk Village’s IUP (Izin Usaha Pertambangan/Mining Business License), Sijuk Village’s IUP, and Batu Itam Village’s IUP. This study also illustrates the orientation of the metal utilization of apatite-ilmenite in district Sijuk.

Based on the formulation of the problem of this research is how the form of code mixing in the interaction of Boladangko village community in the Kulawi district of Sigi district and the factors driving the code mix in the Community Interaction of Boladanko Village in the Kulawi District of Sigi district. The purpose of this study was to determine the form of mixed code speech in the interaction of Boladanko village, Kulawi sub-district, Sigi district. The method used in this study is a qualitative method. Qualitative research methods are intended to describe the form of mixed code speech in the Boladangkokececity of Kulawi Sub-district, Sigi Regency. Based on the results of the study the authors found a mixture of the Kaili language code (Moma) and Indonesian. Mix the code because the speaker forgets the language of his area so that the speaker sometimes deliberately interferes with the code because of the habits and the ease of speech and changes in the way of communication between the speaker and the interlocutor. The following is code mixing data that occurs in the process of community interaction in Boladangko Village, Kulawi Subdistrict, Sigi Regency based on word class, namely, insertion of affixed elements, insertion of elements in the form of clauses, insertion of elements in the form of words and insertion of elements in the form of phrases. The driving factor for code mixing has more to do with the speaker, the speech partner, the function and purpose of the speaker, and the situation of the conversation. The driving factors for code mixing are extralinguistic and intralinguistic factors. Extralinguistic factors related to the character of the speaker such as background, social, religious sense, level of education, and regionalism. Intralinguistic factors relate to the absence of words in the Moma language that are capable of overseeing the concept referred to as the linguistic element that is inserted.

O parafuso como elemento de ancoragem de sistemas de fixação vertebral já é há muito utilizado. Porém a forma de distribuição da tensão gerada por ele na região de ancoragem não está ainda bem clara. O método de elementos finitos (MEF) é um método matemático desenvolvido no século passado e permite, quando em um estudo estático, avaliar reações internas de estruturas ao se aplicar uma força. Este estudo teve por objetivo analisar as tensões e deformações internas geradas por parafusos do sistema de fixação vertebral por meio do MEF. Os Parafusos USS1 de 5, 6 e 7 mm de diâmetro e 45 mm de comprimento (Grupo 1 G1, Grupo 2 G2 e Grupo 3 - G3) e os parafusos USS2 anterior, USS2 posterior de 6,2mm de diâmetro e USS1 de 6 mm de diâmetro e 30 mm de comprimento (Grupo 4 G4, Grupo 5 G5 e Grupo 6 - G6) foram utilizados neste estudo. Para validação dos modelos foram utilizados: ensaio mecânico de arrancamento do parafuso em corpos de prova de poliuretana com densidade de 0,16 g/cm3 e resultados de ensaios de arrancamento encontrados na literatura. Foi confeccionado um modelo tridimensional para cada conjunto parafuso e poliuretana estudado no programa SolidWorks®2006. Foram confeccionados 30 corpos de prova em poliuretana para validação de G1, G2 e G3, sendo 10 corpos de prova para cada grupo. O orifício piloto foi realizado por broca de 3,8 mm para G1 e 4,8 mm para G2 e G3. Os modelos dos grupos G4, G5 e G6 foram validados por resultados encontrados na literatura de ensaios em poliuretana de mesma densidade e orifício piloto realizados por sonda de 3,8 mm para G4 e G5 e 4,8mm para G6. A análise pelo método de elementos finitos, foi realizada no programa ANSYS®Workbench 10.0. A validação foi obtida pela comparação da rigidez relativa obtida no ensaio mecânico e o resultado da simulação pelo MEF. Foram encontradas divergências de 8,3% para G1, 3,1% para G2, 0,5% para G3, 14,4% para G4, 9,5% para G5 e 10,3% para G6, sendo todas consideradas aceitáveis. Validados os modelos, os grupos G4 e G6, utilizados na fixação anterior, foram submetidos à força de compressão, tração e dobramento lateral. Os grupos G5 e G6, empregados na fixação posterior, foram submetidos à força de compressão, tração, flexão e extensão. Na fixação anterior as menores tensões foram encontradas para G4 e as maiores para G6 para todas as forças aplicadas. Na fixação posterior as menores tensões foram encontradas para G5 e as maiores para G6 para todas as forças aplicadas. As maiores tensões foram geradas ao se realizar o dobramento lateral na fixação anterior e a extensão na fixação posterior.Screws have been used to stabilize spine fixation systems. However, stress distribution around them is not clear yet. The finite element method (FEM) is a mathematic model developed in the last century and allows evaluating internal reactions of the structure submitted to a load in a static analysis. The present study aimed to evaluate stress and internal deformation caused by screws of the spine fixation system using FEM. USS1 screws measuring 5, 6 and 7 mm in diameter and 45 mm in length (Group 1 G1, Group 2 G2 and Group 3 G3) and the screws USS2 anterior, USS2 posterior measuring 6.2 mm in diameter and USS1 measuring 6 mm in diameter and 30 mm in length (Group 4 G4, Group 5 G5 and Group 6 G6) were used in the present study. For validation models, mechanical tests evaluating pull-out strength in polyurethane samples presenting density of 0.16 g/cm3, and results of pull-out tests related in the literature were used. Threedimensional (3D) models were built for each screw-polyurethane sample set using SolidWorks® 2006 software. Thirty polyurethane samples were made for G1, G2 and G3 validation, 10 for each group. The pilot hole was made using a 3.8 mm drew for G1, and 4.8 mm for G2 and G3. The G4, G5 and G6 models were validated based on literature results that used polyurethane of same density and pilot hole made using 3.8 mm probe for G4 and G5, and 4.8 mm for G6. The FEM analysis was performed using ANSYS®Workbench 10.0 software. Validation was reached by comparing relative stiffness obtained in mechanical tests and results of FEM simulation. Differences of 8.3% for G1, 3.1% for G2, 0.5% for G3, 14.4% for G4, 9.5% for G5, and 10.3% for G6 were found, but all values were considered acceptable. Validated the models, G4 and G6 groups, used for anterior fixation, were submitted to compression, traction and lateral bending load. The G5 and G6 groups, used for posterior fixation, were submitted to compression, traction, flexion and extension force. In the anterior fixation, lower stress were found for G4, and greater for G6 at all applied forces. In the posterior fixation, lower stress were found for G5 and greater for G6 at all applied forces. Greater stress were caused simulating lateral bending in the anterior fixation, and extension in the posterior fixation.

Full textAbstract:
This thesis comprises nine published papers on an integrated geomechanical evaluation of cap and fault-seal for risking petroleum trap integrity using distinct element and boundary element numerical methods. Paper 1 provides back-ground information and an introduction to the body of research presented in this thesis. In some parts of the Penola Trough, South Australia, the seal lithotype is fractured providing structural permeability and thereby compromising seal competency. This work inferred that existing geomechanical techniques, which only considered stresses on the fault plane, had limited application in the prediction of fracture generation within the country rock away from the well-bore. It also suggested that computational stress modelling techniques may provide a useful tool in this area and similar tectonic provinces.
An important stage of the modelling workflow is analysing the sensitivity of the numerical models to various input parameters. Papers 2 and 3 show that the models are particularly sensitive to fault parameters such as friction angle (o) and cohesion (C). However, fault rock properties are not well understood in petroleum exploration due to depths of investigation and the expense of acquiring core samples.
This thesis develops a new technique, using widely available dipmeter data for the entire borehole. In this, rotations in borehole breakouts caused by discontinuities, in the vertical sense, are used to give qualitative indications of fault rock behaviour (Paper 3). These observations were used to make decisions about fault rock input parameters into the numerical stress models. Paper 8 showed the results of varying fault rock stiffness moduli and fault zone width on the predicted stress within the surrounding rock mass. Where the prevailing stress conditions border between stress regimes, a new and unconventional technique whereby is used to increase confidence in understanding the stress regimes active at a particular depth and/or location (Paper 7). A comparative study of a single fault using three different methods of stress modelling, the distinct / discrete element (DEM), boundary element (BEM) and finite difference (FDM) methods (Paper 7) showed that the DEM underestimated the stress perturbation relative to the other models. Therefore where a clear variation is shown by DEM, there is increased confidence that it does exist and will be enhanced using other codes. Where there is the requirement to model multiple faults, DEM is preferred as the other methods trialled either have restrictions to the number of faults incorporated into the models (FDM) or does not account for full fault interaction and possible moment rotations between fault blocks, such as in the case of BEM.
The application of computational stress modelling offers a new workflow to fully integrate stress studies, cap-seal analysis, fault-seal analysis and structural interpretation to improve the understanding of hydrocarbon leakage risk at the prospect and play scales and was illustrated by way of multiple case study examples (Papers 4, 5, 6, 7 & 8).
The research presented in this thesis has development new concepts and additional workflows which add to the ‘tool-box’ that may be used by those researchers and consultants working in the field of petroleum geomechanics (Paper 9).Thesis (Ph.D.) -- University of Adelaide, Australian School of Petroleum, 2009

Full textAbstract:
Heat waves will occur in Rotterdam with greater frequency in the future. Those affected most will be the elderly – a group that is growing in size. In the light of the Paris heat wave of August 2003 and the one in Rotterdam in July 2006, mortality rates among the elderly in particular are likely to rise in the summer. METHOD The aim of the Hotterdam research project was to gain a better understanding of urban heat. The heat was measured and the surface energy balance modelled from that perspective. Social and physical features of the city we identified in detail with the help of satellite images, GIS and 3D models. We determined the links between urban heat/surface energy balance and the social/physical features of Rotterdam by multivariable regression analysis. The crucial elements of the heat problem were then clustered and illustrated on a social and a physical heat map. RESULTS The research project produced two heat maps, an atlas of underlying data and a set of adaptation measures which, when combined, will make the city of Rotterdam and its inhabitants more aware and less vulnerable to heat wave-related health effects. CONCLUSION In different ways, the pre-war districts of the city (North, South, and West) are warmer and more vulnerable to urban heat than are other areas of Rotterdam. The temperature readings that we carried out confirm these findings as far as outdoor temperatures are concerned. Indoor temperatures vary widely. Homes seem to have their particular dynamics, in which the house’s age plays a role. The above-average mortality of those aged 75 and over during the July 2006 heat wave in Rotterdam can be explained by a) the concentration of people in this age group, b) the age of the homes they live in, and c) the sum of sensible heat and ground heat flux. A diverse mix of impervious surfaces, surface water, foliage, building envelopes and shade make one area or district warmer than another. Adaptation measures are in the hands of residents, homeowners and the local council alike, and relate to changing behaviour, physical measures for homes, and urban design respectively.

AbstractUrban Metabolism (UM) is a scientific phenomenon that comprises individual processes taking place in all cities at different spatial and temporal scales and that is based on the principle of conserving mass and energy. Analysing the metabolism of a city allows one to evaluate the impacts of urban functioning, taking into account the flows of energy, water, nutrients and waste and the materials in general that circulate within a city, and contributing to a multidimensional assessment of sustainability. Many authors have explored the phenomenon of UM and experimented with indices and evaluation methods, but there is still no consensus on the best assessment methods to use.The present paper presents an overview of UM assessment methods, particularly Life Cycle Assessment (LCA) and its possible uses for supporting territorial regeneration. A literature analysis is conducted of the evolution of this method in relation to scales that are different from the single product scale. LCA aims to assess the environmental impacts of the life cycles of single industrial products and services, but over the years it has gained increased attention in the urban planning field. Life cycle, in general, refers to all the phases that characterise the life of elements, comprising not only a single product, but extending this concept also to the wider territorial system. The concept of the life cycle of territorial systems is related to the evolution of the territory as a heritage and as a system of environmental, social and economic resources and services, whose transformation is linked to the different forms of governance. The territorial life cycle is formed by interconnected phases, referred to as the sub-systems of the resources and performance of a territory, that follow a predefined plan scenario. Consequently, the life cycle concept can be compared to that of change and it is closely linked to the analogy of ecosystems and the urban environment, which views the city as an entity in constant transformation.In the last few years, there has been an increase in activity in the LCA application field, with the introduction of scale variations and of the distinction between applications at the level of the single product and applications at the meso and macro levels. In other words, this approach is evolving and applications and hypotheses involving scales different from the micro scale are becoming popular.In this regard, extending the LCA tool to a meso perspective on a municipal scale or an individual urban district scale could prove to be a valid tool for assessing the sustainability of a territory with regard to the metabolic flows and the evolution of its life cycle.

Recent years saw the global wave of new low-carbon economy which is a strategic measure to cope with global warming, and it has gained concerns from many governments. As the representatives of developing countries, China is responsible for “common but distinguishing duty for global climate change.” Many policies have been made to develop low-carbon economy with the hope to advocate and innovate low-carbon economy in some industries and cities during these years. Therefore, it is a theoretical and innovative project to find a low-carbon economical model for various industries and carry out the experiments of low-carbon economy in some cities. Hence, guided by low-carbon economy theory, choosing booming Chinese tourism industry as the object, this paper constructs an operation framework system of low-carbon tourism development from the advantage of low-carbon tourism to the proposal of low-carbon tourism definition so as to conclude an execution scheme of “six elements” of low-carbon tourism with selecting OCT East (Chinese national ecotourism demonstration district) and Mt. Danxia (World Geo-park) as demonstration districts to discuss about models and methods of low-carbon economy in tourism.

Abstract Zircon-based laser ablation inductively coupled plasma-mass spectrometry (LA ICP-MS) trace element imaging and spot analysis methods are used to investigate the petrogenesis of porphyry Cu-related magmas in the Cowal district, Australia. These data discriminate premineralization magmas from synmineralization fertile magmas and provide insights into a complex petrogenesis that culminated in low-temperature, hydrous, and oxidized magma compositions. The intragrain trace element distribution in zircons from synmineralization intrusions spatially correlates with abrupt changes in zircon textures demarked by dissolution surfaces. Mapping of key fractionation, temperature, hygrometer, and oxybarometer indices (e.g., Th/U, Gd/Yb, (Ce/Nd)/Yb, and Eu/Eu*) show in some cases that multiple crystal-fractionation events, including the cofractionation of titanite, apatite, and hornblende, are recorded in single zircon grains spatially separated by dissolution surfaces. These resorbed boundaries are interpreted to record periods of discrete magma recharge events that affected the temperature and trace element budget of the magma. In many cases, the highest relative magmatic water content and highest oxidation signature are concentrated near the crystal rims, which suggests magmatic fertility increased late during the evolution of these magmas—evidently triggered as a result of magma recharge. An evolution to cooler, hydrous, oxidized conditions with transient periods of magma recharge and higher temperature conditions are considered prerequisites for fertile magma petrogenesis in the Cowal district. The relationship between zircon complexity and fertility should be a useful tool for zircon-based fertility studies informed by cathodoluminescence imagery.

Full textAbstract:
Water inrush is a major threat to the working safety for coal mines in the Northern China coal district. The inrush pattern, threaten level, and also the geochemical characteristics varies according to the different of water sources. Therefore, identifying the water source correctly is an important task to predict and control the water inrush accidents. In this chapter, the algorithms and attempts to identify the water inrush sources, especially in the Northern China coal mine district, are reviewed. The geochemical and machine learning algorithms are two main methods to identify the water inrush sources. Four main steps need to apply, namely data processing, feature selection, model training, and evaluation, in the process of machine learning (ML) modelling. According to a calculation instance, most of the major ions, and some trace elements, such as Ti, Sr, and Zn, were identified to be important in light of geochemical analysis and machine learning modelling. The ML algorithms, such as random forest (RF), support vector machine (SVM), Logistica regression (LR) perform well in the source identification of coal mine water inrush.

Full textAbstract:
ABSTRACT Geographically weighted regression (GWR) is an effective model for the investigation of spatially nonstationary relations among variables in the geographical and social sciences. GWR was introduced to the field of mineral exploration to further understanding of the location, controlling factors, and coupling mechanisms related to the triggering of mineralization—in other words, the where, what, and how. Previous studies reported that Cu and Au in a porphyry system present a paragenetic relation at different stages of mineralization, which can be an informative indicator in mineral exploration. As a successor, the current study further applies the GWR model to characterize the paragenetic relation between the ore-forming elements Cu and Au in the Duolong mineral district of Tibet, China, in a spatial scenario. Unlike the spatially varied ore-forming mechanism quantified by the regression coefficients of GWR, the coefficient of determination (R2) is discussed to verify the existence and to evaluate the strength of the paragenetic relation between Cu and Au, because regression coefficients can only inform the mutual influence between one and the other. Furthermore, the fractal and multifractal-based spectrum–area method is adopted to separate the GWR results into anomaly and background. Areas with GWR results that indicate the existence and intensity of a paragenetic relation are mapped as target areas for mineral exploration. The current quantitative recognition of mineralization represents a meaningful and useful extension to the application and interpretation of the GWR model.

Full textAbstract:
The object of this study is to analyze German lexical units/borrowings functioning in the central part of the Boyko dialect of the southwestern Ukrainian dialect group. Lexical germanisms, in particular the names of phenomena and things, features and actions, as well as phraseology, paremiology and other sayings related to life and activities (crafts, agriculture, construction) of the inhabitants of the Eastern Carpathians, were mainly subject to phonetic and wordforming substitutions, they narrowed or changed their semantics. A small part of foreign language elements remains unchanged in the Boyko dialect. Changes in the lexical meaning of words within one action have been revealed in borrowings, polysemy and, less frequently, homonymy have been recorded, and duplication of German words by Ukrainian language units in lexicalized combinations has been observed. As a result of the interaction of the Boyko dialect with the German language (dialects) due to longterm contacts, there is a fairly large number of foreign words registered in the speech of the Boykos; having lost touch with the source language, they are perceived as an integral part of the Ukrainian national language by the indigenous inhabitants of the mountains. Part of the dialectal lexicon (borrowings with narrowed or changed semantics, etc.), collected by the author for three decades using the method of stationary observation in the mode of free narratives (provoked by questions) from representatives of different generations in 30 different settlements (Skole district, Lviv region, Ukraine) served as the material for this study.

Enhancing energy efficiency from the producer to the end-users is a prioritized objective of European energy policies. The most difficult element to understand and to control is the last link, the consumer. Most simulation tools for the estimation of heat demand in buildings are based on the input parameters according to environmental conditions and the features of the materials and equipments. Studies have revealed that even if sophisticated programs are used, a gap between calculated and post occupancy space heating consumption rates occurs. Based on billing history, the present paper proposes a cluster analysis method to identify the grouping trends of habitants’ consumption. For modeling the heat consumption at end-user level and predicting the trends of energy demand, artificial neural networks (ANNs) technique was used. Unlike most prediction methods that have the entire building in view, the proposed technique can be applied to individual apartments situated in condominiums.

Pedestrians are a part of vulnerable road users which safety requires a special attention. Official statistics in Estonia from the last decade returns the following numbers: around 30 % of all road traffic accidents in the country were accidents with pedestrians, 32 % of all traffic fatalities were finished with pedestrian death. Pedestrian crossing has the biggest risk level between all kinds of pedestrian facilities, because it includes a direct conflict point between vehicle and pedestrian traffics. The article presents a method to assess risk of pedestrian crossing users and to determine safety level of this road infrastructure element. This approach is based on observation and collection of infrastructural as well as traffic data, which includes: (1) information about each pedestrian crossing facility, its location and state, (2) data about accidents with pedestrians and their features, (3) data from road traffic measurements. The main advantages of the described method are universality and comprehensiveness. The case study was done in Kristiine district of the city Tallinn, which was chosen as the most typical average district of Estonian capital. Results of this study are also presented in the article.DOI: http://dx.doi.org/10.4995/CIT2016.2016.4124

Full textAbstract:
Abstract Fracture geometries and drainage radius are important parameters for developing a reasonable development plan of a single fractured well. In some unconventional gas reservoir, some scholars observed the phenomenon of single well controlled reserves increasing through the material balance curve, and put forward the idea of district supply. In addition, owing to fracture hits, the fracture geometries of fractured wells are sometimes more complex. Thus, those complex factors bring challenges for parameter estimations. In order to study the variation of the drainage radius and complex fracture geometries in the single model, a well testing based model for a finite-conductivity fractured vertical well in radial composite reservoirs with dynamic supply and fracture networks is established. Based on "successive steady state method", the point source function, pressure superposition principle and boundary element method are used to solve the reservoir model, and the methods of discrete fracture and pressure superposition are used to solve the fracture model. By introducing the rate normalized pseudo-pressure and material balance time, the variable fluid flux is equivalent to the constant fluid flux. Combined with the inversion idea of well test, the drainage radius value and fracture geometries are solved by fitting the log-log curves of pressure response, and case studies are performed. The results show that the drainage radius increases with the increase of production time and finally tends to a certain value, and it has a good exponential relationship with time. Also, the fracture geometries of the typical well are multiple-radial fracture networks. Through the study of dynamic drainage radius, the controlled reserves of single well in unconventional gas reservoir can be better determined, and it can also provide theoretical basis for fracture evaluation, productivity prediction and enhanced recovery study of the same type of unconventional gas reservoir.

Full textAbstract:
The propagation and coalescence processes of two initially semi-elliptical surface cracks in a plate at high temperature are predicted by using a modified creep-damage model implemented with the numerical method. The creep growth of multiple cracks during pre-coalescence and coalescence periods is investigated in detail. For the purpose of comparison, the step-by-step fracture-mechanics-based finite element technique is also employed. The results indicated that, before coalescence, the cracks grow steadily but relatively rapidly in the adjacent district; after the cracks coalesce, the concave positions of the newly combined crack front exhibit a considerably high growth rate. Compared with the fracture mechanics approach, the numerical approach based on the modified creep-damage model enables to give more detailed information on creep crack initiation and more reliable estimate of propagation. In addition, the combination rules given by existing standards are also examined.

Efficient and sustainable methods of clean fuel and energy production are needed in all countries of the world in the face of depleting oil reserves and the need to reduce carbon dioxide emissions. Some countries are developing technologies that could be named zero carbon technologies. The presented article will show how hydrogen technologies could be implemented with renewable technologies and nuclear technology. Nuclear technology produce very cheap electricity and could produce also cheap energy like heat and vapour. This technology should be used in nuclear power plants to develop other products like hydrogen, biofuels or district heating. One of the biggest opportunities for nuclear energy technology is to produce hydrogen. Some countries like Canada and US are in preparation to build hydrogen villages. However, a key missing element is a large-scale method of hydrogen production [1–5]. As a carbon-based technology, the predominant existing process (steam-methane reforming (SMR)) is unsuitable. This paper focuses on a production of hydrogen in connection with a nuclear power plant. We will show the technologies which allow the coupling between a nuclear power plant and hydrogen technologies.

Full textAbstract:
This paper describes a novel approach for optimizing a district heating distribution network under various flow rate conditions. For district heating systems, the demand or the flow and pressure at each node varies over the time of year. The flow control that affects the operational cost can be based on the variable speed and the on/off control on serial pumping or pressure controlled valves. In the pipe system design, the topology, or the pipe layout, and the pipe diameter is optimized using genetic algorithms. Standardized methods are used for calculating the pipe thickness, supports, anchors and the thermal expansion loops. The interconnection between the pipe system and the pump station design is discussed. The objective is to minimize the total or life cycle cost (capital maintenance and operational cost), subject to ensuring demands or constraints at all points. The results are compared to classical methods where the pump station and the pipe system are designed separately and the improvements are discussed. The problem is formulated by developing an objective function where the optimization parameters define the pump arrangement, pipe system topology, and pipe diameters. The pump station and pipe system optimization consist of selecting components from a pre-defined set of elements and is implemented with discrete decision variables. Optimization of pipe elements consists of optimizing the diameter, after the topology has been defined, and is implemented with discrete variables. Flow distribution and pressure analysis is performed. Thicknesses, pressure classes, supports, expansion loops and anchors are not part of the optimization parameters, but are determined during the evaluation of the objective function. Each time the objective function is evaluated, the pipe system is designed in a sub-optimization according to given loads. The pressure head constraints are used to design the pumping curves. The method is tested on a district heating system in Reykjavik, Iceland.

Full textAbstract:
Using the system approach, we have developed a simulation model for the long-term forecast of the content of toxic chemical elements in grain crop yield. The study was carried out by the example of wheat cultivated in Altai Krai — one of the main grain-producing regions of Russia. Wheat crops were sampled in 10 municipal districts of Altai Krai, which characterize seven different edaphic-climatic zones. The average long-term values of mean monthly air temperature and monthly precipitation for each sampling area were identified using GIS and data of the Interactive Agricultural Ecological Atlas of Russia and Neighboring Countries. A total of 19 chemical elements were considered, i.e. Pb, As, Cd, Hg, Na, Mn, Zn, Cu, Fe, Co, etc. It is shown that content of Pb, Na, Mn and Cu in wheat depend on climatic characteristics of the cultivation area. Regression dependences of element content on the average long-term air temperature and precipitation were established. Based on normalization and spatial generalization of air temperature and precipitation providing the uniform dynamics of their relative monthly values (in percent) throughout the study area, a forecast of their changes was made for 2030. A procedure for grain sampling, GIS technologies for processing meteorological and cartographic data, methods for predicting regional climate changes and establishment of quantitative relationships of chemical elements content in grain with climatic characteristics – all together make up the integral predictive simulation model for toxic substance content in grain crop yield. The model was used for estimation of Pb, Na, Mn, Cu changes in wheat by 2030. The lead (Pb) content in wheat crop delivered to elevators from certain municipal districts will exceed the maximum allowable concentration for breadgrain after 2030. Unlike Pb, Na, Mn, Cu, the content of other metals in wheat grain weakly correlate with long-term changes in air temperature and precipitation; therefore, it can hardly change significantly.

In the context of the pandemic condition caused by the coronavirus Covid 19, it is obvious that economic sectors dependent on movement of goods and people between regions will be less economically productive. Undoubtedly it is tourist industry (TI). Partial compensation of impacts and risks is practicable by appropriate tools, in this context it is client relationship management (CRM). Basic TI services are related to a destination which is a geospatial factor determining supply and demand. Destination isn´t isolated entity, it is dependent on environment (between other and administrative). Data processing is always related to a territorial unit which is characterized, between others, relevant infrastructure which is needed for provision of services. One characteristic of infrastructure is relation between elements of infrastructure, which can be defined as interdependence of elements, e.g. spatial. The aim of the contribution is to demonstrate the geospatial relationship between selected elements of supply and demand in the TI given accommodation capacities and the number of overnight stays. Defaults data are evaluated by geospatial analysis methods, especially precedent analysis showing changes of values between elements analyzed on the infrastructure. Infrastructure is based on administrative division of Czech Republic, basic data are divide into districts and modified to regions by minimum distances. Infrastructure is generated by passage of autonomous agents. The results of the work demonstrate spatial dependencies and indicate the need to examine the relationships between quantities based on the gradient of quantities in the space, which is evident, for example, on the behavior of the average number of overnight stays between the districts of Brno city and Brno countryside.

Built environment indicates of street space quality have been carried out in a profound influence on the image of city，human behavior and public health. A street that is considered as a fundamental element in urban studies. Of the 5 elements of the image of a city, i.e. landmarks, paths, nodes, districts and edges, suggested that the paths are the most dominant elements, the research of which would provide a basis for the clustering and organization of the meanings and associations of the other four elements and the city as a whole. Additionally, taking a quantitative measurement of the visual appearance of street space has proven to be challenging because visual information is inherently ambiguous and semantically impoverished. Recent developed image semantic segmentation techniques and Street View Picture dataset make it possible to eliminate the previous restrictions, Furthermore, bringing forward a research paradigm shift. Lilong, which typically represent for historical street space in Shanghai, are selected for empirical study .This paper attempts to measure subjective qualities of the Lilong environment comprehensively and objectively. By employing Street View Picture, pictorial information is the proxy for street physical appearance, which utilizes the image semantic segmentation techniques (The model used in this study is Deep lab V3 which can achieve a 85.7% pixelwise accuracy when classifying 150 categories of objects) to parse an street scene into scene elements, such as buildings, roads, pavement, trees, cars, pedestrians, and bicycles. Then, the elements corresponding to each street point in the two directions of spatial coordinate are summarized and the average value is calculated. The potential factors were calculated based on 3-dimensional composition calculation of greenery, openness, enclosure and motorization may serve as indicators for inferring. The outcomes were used to evaluate the street types, functionality, quality, time, status, and human activities of a street. The result indicates that visual quality of Lilongs are barely satisfactory, while some regeneration projects in the historical protection block is better. A lot of Lilongs are in shortage of visual green, relative more continuous but with low vertical diversity. In the most recent 6 years, less than 2.74 million square meters Lilongs are not regenerated which are mainly slow building renovation. A series of quantitative analyses demonstrates the ability and great potential of auto-calculation method useful for auditing street environments.

Full textAbstract:
The U.S. Congress codified the National Historic Preservation Act of 1966 (NHPA) to provide guidelines and requirements for preserving tangible elements of our nation’s past. This preservation was done primarily through creation of the National Register of Historic Places (NRHP), which contains requirements for federal agencies to address, inventory, and evaluate their cultural resources, and to determine the effect of federal undertakings on properties deemed eligible or potentially eligible for the NRHP. This work inventoried and evaluated the historic landscapes within the National Landmark District at Fort Huachuca, Arizona. A historic landscape context was developed; an inventory of all landscapes and landscape features within the historic district was completed; and these landscapes and features were evaluated using methods established in the Guidelines for Identifying and Evaluating Historic Military Landscapes (ERDC-CERL 2008) and their significance and integrity were determined. Photographic and historic documentation was completed for significant landscapes. Lastly, general management recommendations were provided to help preserve and/or protect these resources in the future.
