Experiencias y medidas socioeducativas en los dispositivos penales juveniles
Authors: Iuri Teresa
Published: August 2019

En 2015 se realizó un relevamiento  nacional sobre adolescentes en conflicto con la Ley Penal. La metodología utilizada fue un censo, que  se realizó de manera simultánea en todas las jurisdicciones del país, mediante instrumentos de recolección de datos que fueron suministrados por informantes clave de cada jurisdicción.  El Informe con los resultados obtenidos es una  publicación realizada en forma conjunta por la Secretaría Nacional de Niñez, Adolescencia y Familia (SENAF) y el Fondo de la Naciones Unidas para la Infancia (UNICEF)  y se tituló “Relevamiento  Nacional sobre Adolescentes en conflicto con la Ley Penal Año  2015”. En el segundo capítulo se examinaron experiencias y medidas socioeducativas  puntuales en la gestión de los Dispositivos Penales Juveniles bajo la órbita de la SENAF, con sede en la Ciudad Autónoma de Buenos Aires y de seis provincias representativas de las distintas regiones de la Argentina. Desde el ámbito educativo interesa conocer cómo se significan las experiencias y medidas educativas para este grupo de niños y jóvenes atento el marco de leyes que los protegen. Se analizan desde una mirada socio pedagógica. La Pedagogía construye  una mirada pedagógica especializada. A través de este trabajo se espera dar cuenta del recorrido legislativo y de intervenciones que seis provincias han ido transitando durante los últimos diez años,  y con la convicción que la socialización de buenas prácticas socioeducativas obrará como un estímulo al mejoramiento  educativo del  Sistema Penal Juvenil en otras provincias. Las mismas deben orientarse a  trazar con cada joven un escenario que lo aleje de la transgresión de la norma penal.
Seasonal inventory of Heavy Metals on Vehicular Polluted Soils and Roadside Distance Supporting Arable Crop
Production in Umuahia Metropolis, Nigeria
Authors: Eteng Ernest
Published: August 2019

This study was conducted between February and September, 2018 to evaluate heavy metal concentrations of road dust soils supporting arable crop production along five major roads connecting the Umuahia Metropolis to surrounding cities. Thirty soil samples from five major roads were collected during the dry and wet seasons at 10 m, 20 m and 30 m distances from road edges. The heavy metals were analyzed using tri-acid digestion. The results showed that mean concentrations of the heavy metals varied widely and had significant different between the seasons, among the five major roads and usually, decreased with increased in distance from the road. Accordingly, the study indicates that, the relative sequence of abundance followed the order: Fe > Zn ≥ Pb > Cd > Cr ≥ Cu > Co > Ni > Se ≥ As. Higher content of the heavy metals was recorded during the dry season (83.94 mg kg-1) than the wet season (74.72 mg kg-1). Among the roads, higher content of the heavy metals was recorded in Uzoakoli road (105.50 mg kg-1) while, the least was recorded in Aba road (53.37 mg kg-1). Similarly, higher contents of the heavy metals were recorded within the distance of 10 meters (94.56 mg kg-1) while, the least was recorded in 30 meters (61.73 mg kg-1) away for the roadside. Since the roadside soils in Umuahia Metropolis are being extensively cultivated for agricultural production, proper biomonitoring of activities in the urban environment should be done as often as possible to enlighten the public on dangers of heavy metal pollution.

Published: August 2019

The assessment of the clientele satisfaction on front line services in the University is a vital step to improvement. Hence, this study assessed how frontline personnel and services uphold human dignity by meeting customer and statutory requirements specified in the Anti-Red Tape Act. This study determined the respondents’ level of satisfaction on front line services of the university. A stratified simple random technique was utilized in identifying the actual student respondents while purposive sampling was used for parents and alumni respondents. The findings also indicated that the clienteles were not in common agreement on the level of their satisfaction towards the services of frontline offices in the University. The parent stakeholders were far more satisfied with the services availed from front line personnel of the institution than the students and alumni. In general, the University front line services are compliant with the ARTA provisions of the Civil Service Commission.
The Implementation of Outcome-Based Education in a State University
Authors: CAYOT MERFE D.
Published: August 2019

Higher educational institutions are encouraged to implement the Outcome-Based Education to prepare instructors to be competitive and produce graduates who are ready to meet the global job needs. To determine the level of implementation of the Outcome-Based Education (OBE) in Central Philippines State University, the researcher employed the sequential explanatory mixed-method design which involves two phases: the quantitative followed by qualitative. The quantitative data were collected through a validated survey instrument, while the qualitative data were gathered from the participants through an in-depth semi-structured interview which culled out their experiences on the implementation of the Outcome-Based Education. The findings of the study revealed that Outcome-Based Education standards were moderately implemented in the university. This means that the learning experiences of students and the teaching methodology could hardly develop their skills to attain the intended learning outcomes. Qualitatively, the results yielded different themes that brought forth an eidetic insight that the OBE implementation is collaborative and value-laden effort: bridging theory and practice of the academic community. The research findings were used as a basis for designing the proposed CPSU-Operational Plan using the Approach, Deployment, Learning, Integration (ADLI) model that can be adopted and implemented by the University.

Samsung : le modèle de croissance entre exemplarité et originalité (1938-2007)
Authors: Barjot Dominique , Park-Barjot Rang-Ri
Published: August 2019

De tous les groupes Coréens, Samsung est, de loin, le plus connu dans le monde. Créé en 1938 pat Lee Byung Chull (1910-1987), s’il reste de loin le plus important de Corée du Sud, il ne répond qu’imparfaitement au modèle canonique du chaebol. Il offre en effet un bon exemple de path dependency. Dans une première phase de son histoire, de 1938 à 1969, il s’est d’abord intéressé au commerce, avant de mettre à profit la reconstruction massive, qu’a entraîné la Guerre de Corée, pour se lancer dans l’industrie (textile et agroalimentaire). Tout en réalisant une belle percée dans le commerce international, le groupe s’inscrit avec succès dans les priorités successives du développement économique sud-coréen, basé sur les exportations (pétrochimie, constructions navales, automobile, btp , ingénierie, électronique). Grâce à l’électronique, mais aussi à l’ingénierie, il s’impose, entre 1969 et 1987, sur le marché international. À la mort de Lee Byung Chull, son fils Lee Kun Hee en fait une puissante corporation à l’américaine, bénéficiant, grâce à un intense effort de recherche-développement, d’un avantage compétitif croissant dans l’électronique. Cette réussite repose, entre autres, sur un système social original, qui puise largement aux sources du néoconfucianisme. En même temps le groupe a su réaliser une synthèse entre les technologies et les modes de management japonais, américains et allemands.
Le déclin de la sidérurgie européenne est-il inéluctable ?
Authors: Mioche Philippe
Published: August 2019

La sidérurgie européenne a dominé la production mondiale d’acier. Mais en 2013, la Chine a produit, à elle seule, la moitié de l’acier du monde (49.8 %). Elle est devenue « la forge du monde ». L’industrie sidérurgique globale n’est pas en crise en dépit des cycles, et elle continue d’augmenter. Le déclin relatif de la sidérurgie européenne s’amorça dès 1952. Depuis la crise de 2008, la sidérurgie est en décroissance en valeur absolue. Le poids de « l’Europe » est passé de plus de 40 % dans l’entre-deux guerres à 10 % en 2013. Les indicateurs sommaires à propos des technologies mises en œuvre ne permettent pas de conclure à la supériorité technologique de l’Europe. Toutefois, l’Europe conserve un avantage dans les produits plats à meilleure valeur ajoutée. La balance commerciale européenne des produits longs est excédentaire sauf exception et celle des produits plats tend à l’équilibre. La tendance est au repli sur la consommation intra-européenne dans une UE où la croissance stagne. Le management européen recule dans le classement mondial des firmes sidérurgiques. La sidérurgie est dominée par Arcelor-Mittal, une entreprise globale, et par Tata, une entreprise indienne. La première entreprise « européenne » dans le classement est Thyssen. En longue durée, le mouvement de la production d’acier est un remarquable indicateur de l’histoire économique globale. La troisième mondialisation du IIIème millénaire a accéléré le déclin de la sidérurgie européenne. Ce déclin se vérifie dans presque tous les domaines abordés (production, commerce, poids des entreprises, management). La Commission européenne le sait et le dit. Les décideurs nationaux et les citoyens européens doivent comprendre que l’avenir des hauts-fourneaux n’est pas serein.
¿Una familia real en el trono de España? Ritualidad política y ceremonias dinásticas en la construcción del Estado liberal (1833-1868)
Authors: San Narciso Martín David
Published: August 2019

Las ceremonias crean una imagen dinámica —temporal y espacial— de cómo se imagina una comunidad social, siendo unos espacios de negociación entre distintas culturas políticas. La monarquía ocupó tradicionalmente un lugar preeminente en esta conquista del espacio público que, en el siglo XIX, compartió con las nuevas instituciones representativas. Pese a todo, el naciente Estado liberal no supo configurar su propio corpus ceremonial, en parte por la gran conflictividad entre las familias políticas. Por ello, aquellos eventos puramente políticos que debían celebrar al Estado introdujeron elementos monárquicos, instrumentalizando su legitimidad y solidez ceremonial. Igualmente, las ceremonias dinásticas de la monarquía devinieron en fiestas del Estado, encarnando la Familia Real el cuerpo de la nación. Este artículo analiza los discursos y representaciones generadas en eventos de la Familia Real —como bodas, bautizos, etc.— en un momento de construcción del sistema político liberal, de desarrollo del nacionalismo y de redefinición de los roles de género.

Published: August 2019

The purpose of the research findings, given in article, is aimed to determine the rational compounds of concrete with an average cubic compressive strength less than 20 MPa with minimum required expenditures of cement. To reach the goal, mathematical planning of the experiment was used with variability of cement consumption from 90 to 190 kg / m3 in the compositions of the concrete mixture, and for the fine-grained filler from tails of processed ores, the consumption was like at 100 to 400 kg / m3. The result of processing experiments has shown us the dependences of the change in strength and coefficient of efficiency of the use of cement of the factors involved. Optimized values increase most intensively with minimum cement consumption and a change in the consumption of fine filler within the limits of the study. The highest coefficient of efficiency of use of cement is expressed by the ratio of the achieved strength per unit mass of used cement in the concrete mix and it was obtained at a cement consumption of 90 kg / m3 and a filler of 400 kg / m3. Using the obtained dependences of optimized values on the factors under study, the composition of concrete may be predicted with a strength up to 20 MPa with the required amount of filler.

Published: August 2019

It is presented the study of the beam samples reinforced with metal armature, BFRP armature and beams with hybrid reinforcement using metal and BFRP armature. Half of the tested samples of beams were manufactured on concrete with river sand, as a fine aggregate. The others were made on concrete with fractionated fine wastes of Mining and Beneficiary complex (MBC) instead of the river sand. The tests were carried out by static loading of the scheme of a single-run free beam loaded in the thirds of gear. It was established that the beams reinforced with BFRP armature and the beams with hybrid reinforcement showed an increase of strength, about 40%, compared with the beams reinforced with metal reinforcement. The deflections of the beams reinforced with BFRP armature were 315% -331% higher than the deflections of the beams reinforced with metal reinforcement and 165% -205% higher than it is allowed by standards. The use of hybrid reinforcement allowed reducing their deflections in two times compared to the beams reinforced with BFRP armature. At a load level of 60% of the destructive, the deflections of beams with hybrid reinforcement BFRP and metal armature did not exceed the maximum permissible norm. When concrete samples manufactured, the substitution of the river sand with fine fractionated wastes from the Mining and Beneficiary complex (MBC) did not affect their durability and deformability (the difference between the values according to these indicators is within the statistical error).

Authors: Azizov Taliat , Derkowski Wit , Jurkowska Nadzieja
Published: August 2019

The paper discusses the principles of precast concrete hollow-core slabs taking into account their spatial work. It is shown that consideration of spatial work makes it possible to determine the forces in individual floor slabs significantly more precise. The fact that strain redistribution between precast floor slabs depends on slabs’ bending and torsional stiffness is shown. The research has been mostly devoted to determination of the bending stiffness with regard to formation of cracks and the change in torsional stiffness, especially considering the presence of normal cracks, which is still unstudied. This paper presents the technique for determining the torsional stiffness of hollow-core slabs with normal cracks. In order to determine the components included in the resolving system of equations, it is proposed to use an approximation method based on the processing of numerical data using spatial finite elements.
Nonlinear Dynamic Analysis of a Reinforced Concrete Frame by the Boundary Element Method

Published: August 2019

Direct dynamic analysis of reinforced concrete frame buildings taking into account the nonlinear and plastic properties of materials by the finite element method is connected with the solution of a system of solving equations of very high order. This is due to the fact that it is necessary to split the beams and columns that form the structure into a large number of finite elements, since the deformation properties of concrete are different in the compressed and stretched zones, as well as in the loading and unloading zones. In this paper, we propose a method for investigating nonlinear spatial oscillations of a flat reinforced concrete frame, based on the method of boundary elements, which leads to a much smaller amount of computational work.

A spatial problem of the theory of elasticity for the layer with an infinite round cylindrical inclusion is investigated. At the boundaries of the layer, displacements are given. The cylindrical elastic inclusion is rigidly coupled with the layer and their boundary surfaces do not intersect. The solution to the spatial problem is obtained by the generalized Fourier method, with regard to the Lamé system of equations. The obtained infinite systems of linear algebraic equations are solved by a reduction method. As a result, the values ​​of displacements and stresses in the elastic body are determined. A comparative analysis of the stress state for different geometrical parameters is carried out, and a comparison is made with the stress state in the layer with a cylindrical cavity.

Published: August 2019

The construction of a mathematical model and the development of an algorithm of free vibrations investigation in the three-layered circular shell with a light-weight aggregate supported by annular rigidity ribs are considered in paper. The hypotheses of Kirchoff-Lyav are accepted for external bearing layers of shell and for aggregate there is accepted the linear law of tangential displacements change by thickness.
The boundary conditions of a shell region closed between the ribs are established. Using the boundary transition, conditions along the lines of the ribs, taking into account and without deformations of displacement in the ribs, but without taking into account the torsional rigidity in the ribs are determined. The equation of motion of supported three-layered shell is obtained. The frequencies of free vibrations were investigated and values of parameter of the first frequency of free vibrations for a shell, supported by one and three rigidity ribs, were calculated. There are given values depending on the physical and mechanical properties of materials and geometric dimensions of the shell, the curvature parameter, and the rigidity parameter of an aggregate.
Calculation of Non-Homogeneous Anisotropic Rectangular Plates with Arbitrary Fixation on the Contur
Authors: Zavrak Nikolay
Published: August 2019

The developing of the effective methodic of elastic orthotropic plates’ calculation and the research on the base of their state under different boundary conditions are of great importance nowadays. The representation of the received results in the form, convenient for practical use, is also important. For practical applications in engineering are important tables for determining deflections and internal forces of structures. Such tables for the isotropic case under various conditions of plate support on the contour are given in many works. As for the anisotropic plates, there are no such tables, with the exception of one Huber table compiled for a freely supported rectangular orthotropic plate, depending on the relationship between the stiffness values. Here is a method of calculating the non-homogeneous anisotropic rectangular plates with arbitrary fixation on the contour is set forth, which is reduced to a boundary value problem. The main idea of a calculated general methodic of linear marginal differential tasks calculation is based on underlying of the main part of a solution. Such approach is proved by means of development and some generalization of common positions of a variational method of marginal tasks of mathematical physics of self-conjugated tasks solution. To solve a system of equations in terms of displacements using finite difference method (FDM) in combination with different variations of analytical solutions. It is advisable to construct a numerical solution of the problem so that in difficult cases the support fixing and uploading solution sought, not directly, but in the form of amendments to the known solution for simple cases of reference to consolidate and uploading at finding the solutions which the analytical methods or the FDM with sparse mesh may be used. Given as examples are the results of calculation for a series of square orthotropic plates with a fixed boundary under the action of uniformly distributed load.
The Solution of the Shells Theory Problems by the Numerical-Analytical Boundary Elements Method
Authors: Krutii Yurii , Surianinov Mykola , Chaban Vitalii
Published: August 2019

The application of the numerical-analytical boundary elements method (NA BEM) to the calculation of shells is considered. The main problem here is due to the fact that most of the problems of statics, dynamics and stability of shells are reduced to solving an eighth-order differential equation. As a result, all analytical expressions of the NA BEM (fundamental functions, Green functions, external load vectors) turn out to be very cumbersome, and intermediate transformations are associated with eighth-order determinants.
It is proposed along with the original differential equation to consider an equivalent system of equations for the unknown state vector of the shell. In this case, calculations of some analytical expressions related to high-order determinants can be avoided by using the Jacobi formula. As a result, the calculation of the determinant at an arbitrary point reduces to its calculation at the point , which leads to a significant simplification of all analytical expressions of the numerical-analytical boundary elements method.
On the basis of the proposed approach, a solution is obtained of the problem of bending a long cylindrical shell under the action of an arbitrary load, the stress-strain state of which is described by an eighth-order differential equation. The results can be applied to other types of shells.

Published: August 2019

In this article is determined the ratio between effective elastic characteristics of the fibrous transversally isotropic material. Fibrous uniaxial material, which consists of the isotropic elastic matrix and fiber, is in the focus of attention. It is assumed that mechanical properties of components under stretching and compression are different, notably matrix material and fiber material are multi-modular. Transverse stretching and transverse compression of composite cell are considered. Two problems for each type of strain are solved. In the first problem stresses and displacements of matrix and fiber under conditions of their common axisymmetrical deformation are determined. Subsequently similar characteristics for the cell deformation of the homogeneous transversally isotropic material as a composite are determined. Ratio between effective composite’s characteristics is solved from the conditions of equality of the axial displacements of the composite’s cell and radial displacements on its surface. The relation of the calculated ratio from volume fraction of fiber in a composite is analyzed.

Authors: Chepurna Svitlana , Borziak Olga , Zubenko Svitlana
Published: August 2019

In modern construction, a large variety of small architectural forms are used, for the production of which cement concrete is traditionally used, which should have improved physical and mechanical properties and decorative properties, while having a low cost. Improvement of these properties is achieved through the use of carbonate additives - highly dispersed chalk. Experimental results show that the addition of highly dispersed chalk affects the structure of cement stone, which is represented by low-base hydrosilicates, calcium hydrocarbonate and complex compounds that create a dense structure, which reduces the permeability of the material for corrosive media. It is assumed that the addition of highly dispersed chalk improves the elastic-plastic properties, increases the crack resistance, which provides high performance properties of concrete.

The effect of mineral filler compounds on vapor permeability and hygroscopic properties of water-based polymer dispersions and the possibility of their use as decorative and protective material for stucco facades finishing was studied. According to Facade Protection Theory (H.M. Künzel), the assessment criterion was vapor permeability and water vapor diffusivity. The pairwise correlation of building physical properties of water-based polymer dispersions in the coordinates of Künzel's diagram clearly demonstrates that, in terms of hygroscopic, all the samples studied correspond to the low hygroscopic class, and in terms of vapor, they are close to high water vapour diffusion rate class.

Arctic clouds in ECHAM6 and their sensitivity to cloud microphysics and surface fluxes
Authors: Kretzschmar Jan , Salzmann Marc , Mülmenstädt Johannes , Quaas Johannes
Published: August 2019

Abstract. Compared to other climate models, the MPI-ESM/ECHAM6 is one of the few models that is able to realistically simulate the typical two-state radiative structure of the Arctic boundary layer and also is able to sustain liquid water at low temperatures as is often observed in high latitudes. To identify processes in the model that are responsible for the abovementioned features, we compare cloud properties from ECHAM6 to observations from CALIPSO-GOCCP using the COSP satellite simulator and perform sensitivity runs. The comparison shows that the model is able to reproduce the spatial distribution and cloud amount in the Arctic to some extent but a positive bias in cloud fraction is found in high latitudes, which is related to an overestimation of low- and high-level clouds. We mainly focus on low-level clouds and show that the overestimated cloud amount is connected to surfaces that are covered with snow or ice and is mainly caused by an overestimation of liquid-containing clouds. The overestimated amount of Arctic low-level liquid clouds can be related to insufficient efficiency of the Wegener–Bergeron–Findeisen (WBF) process but revising this process alone is not sufficient to improve cloud phase on a global scale as it also introduces a negative bias over oceanic regions in high latitudes. Additionally, this measure transformed the positive bias in low-level liquid clouds into a positive bias of low-level ice clouds, keeping the amount of low-level clouds almost unchanged. To avoid this spurious increase in ice clouds, we allowed for supersaturation with respect to ice using a temperature-weighted scheme for saturation vapor pressure but this measure, together with a more effective WBF process, might already be too efficient at removing clouds as it introduces a negative cloud cover bias. We additionally explored the sensitivity of low-level cloud cover to the strength of surface heat fluxes; by increasing surface mixing, the observed cloud cover and cloud phase bias could also be reduced. As ECHAM6 already mixes too strongly in the Arctic regions, it is questionable if one can physically justify it to increase mixing even further.
Computing water flow through complex landscapes – Part 1: Incorporating depressions in flow routing using FlowFill
Authors: Callaghan Kerry L. , Wickert Andrew D.
Published: August 2019

Abstract. Calculating flow routing across a landscape is a routine process in geomorphology, hydrology, planetary science, and soil and water conservation. Flow-routing calculations often require a preprocessing step to remove depressions from a DEM to create a “flow-routing surface” that can host a continuous, integrated drainage network. However, real landscapes contain natural depressions that trap water. These are an important part of the hydrologic system and should be represented in flow-routing surfaces. Historically, depressions (or “pits”) in DEMs have been viewed as data errors, but the rapid expansion of high-resolution, high-precision DEM coverage increases the likelihood that depressions are real-world features. To address this long-standing problem of emerging significance, we developed FlowFill, an algorithm that routes a prescribed amount of runoff across the surface in order to flood depressions if enough water is available. This mass-conserving approach typically floods smaller depressions and those in wet areas, integrating drainage across them, while permitting internal drainage and disruptions to hydrologic connectivity. We present results from two sample study areas to which we apply a range of uniform initial runoff depths and report the resulting filled and unfilled depressions, the drainage network structure, and the required compute time. For the reach- to watershed-scale examples that we ran, FlowFill compute times ranged from approximately 1 to 30 min, with compute times per cell of 0.0001 to 0.006 s.

Abstract. Traveling is a basic part of our daily life, whenever a person wants to travel e.g. from home to workplace, the essential question that rises is which route to follow. The choice of a route also varies based on traveler’s interest e.g. visiting hospital on way back to home or traveling on a greener route. This varied route planning may be easy for any person in his local neighborhood, however in a new neighborhood and increasing number of options e.g. possible restaurant options to visit, a guiding system is required that suggests an optimal route according to traveler’s interests i.e. answering semantic queries. Most of the existing routing engines only answer geometric queries e.g. shortest route due to lack of data semantics and adding semantics to a routing graph requires a semantic data source. Geo-semantics can be added through combination of GIS and semantic web. Semantic web is an extension of World Wide Web (WWW) where the content is maintained and structured in a standard way that is understandable by machines; hence providing linked data as a way for semantic enrichment, in this study the semantic enrichment of routing dataset. To use this semantically enriched routing network a routing application needs to be developed that can answer the semantic queries. This research serves as a proof of concept for how linked data can be used for semantic enrichment of routing networks and proposes a prototype routing framework and application designed using open source technologies along with use cases where semantic routing queries are addressed. It also highlights the challenges of this approach and future research perspectives.

Abstract. Citizen science is an efficient tool for data collection for scientific projects. In the framework of SIMILE Interreg Italy-Switzerland project, the citizen’s contribution to monitor the quality of lakes water has been envisaged. In the initial phase of this research, state of art of citizen science and water quality monitoring was investigated. The analysis of past and current projects, governed by different organizations and communities, pointed out a variety of tasks that can be accomplished by citizens. In these studies, authors stressed suitability of smartphones for the fulfilment of various assignments given to citizens. Due to that, in this research, different smartphone applications for water quality monitoring were tested and analyzed. Despite the fact that many applications for water quality monitoring are freely available, none of them is open source. Hence, this paper is proposing the design of a new application, for the purposes of SIMILE project, that will be free and open source, addressing not just users but also developers giving them a possibility for customization and improvement.

Published: August 2019

Abstract. This paper presents a case of developing open geospatial analysis functions and a processing toolbox as parts of UN Open GIS Spiral 3 activities. A comprehensive study focused on the use of geospatial analysis at the UN operations has been carried out, which covered various UN operations such as situational awareness, security operations, military operations, protection of civilians, epidemiological analysis, and so on. Four requirements on development of 1) primitive geospatial analysis functions, 2) processing toolbox or processing environment like WPS request builder of GeoServer, 3) model builder, and 4) management of the model builder were clarified through the study. By focusing the first and second requirements, a development architecture was proposed based on JAVA and GeoTools. The scope of implementation and its assessment were described. In addition, a use-case introduced a way of using geospatial functions developed in this research to analyse geostatistic factors that affect to occurrence of Ebola disease. Through the use-case study presented in the paper, I would like to share the experiences and lessons about the development of geospatial analysis functions, which would be used as a reference for other developments and applications.

Abstract. Approximately by the year 2030, 40% of population of a country will be urbanised. This indicates a tremendous opportunity in sector of constructing units for fulfilling Residential as well as commercial requirements. Construction activity takes place on land, it must be noted that land solely is not responsible. There are various regulations which affect the extent to which construction/land utilization can takes place. The two most significant factors which affects utilization of land are Zoning and Development Control regulation. Zoning will broadly determine land use while DCR varies depending on size of plot, height achieved by a construction activity and purpose for which it is being used. Development plan determines zone in which a land will be lying (i.e., from Macroscopic point of view), it determines the activity permitted and largely the FSI allotted for each zone. While General Development Control Regulation (GDCR) gives detailed structure regarding permitted activities for the land as well as minimum area of construction depending on its typology. In addition to its height as well as margin depends on factors like Road length and surrounding structure. Using the buildable area of a plot, the total built-up area in a city can be calculated based on the FSI provided in various zones that helps in providing sufficient infrastructure for the future It also gives an estimate on how much land needs to be opened up in future to accommodate the future population Study focuses on developing a Geospatial solution which can incorporate all these factors when a particular construction activity needs to be conducted. By obtaining buildable are one can forecast various infrastructural elements which needs to be implant along with various emergency provision of Fire Safety and Identify the Roof tops to fixed up the Solar penal, develop a public utility, other such.
FAST INSIGHT ABOUT THE SEVERITY OF HURRICANE IMPACT WITH SPATIAL ANALYSIS OF TWITTER POSTS

Published: August 2019

Abstract. Social media could be very useful source of data for a people interested in disasters, since it can provide them with on-site information. Posted georeferenced messages and images can help to understand the situation of the area affected by the event. Considering this type of resource as a real-time crowdsource of crisis information, the spatial distribution of geolocated posts related to an event can represent an early indicator of the severity of impact. The aim of this paper is to explore the spatial distribution of Twitter posts related to hurricane Michael, occurred in the USA in 2018 and to analyse their potential in providing a fast insight about the event impact. Kernel density estimation has been applied to explore the spatial distribution of Twitter posts, after which Hot Spot analysis has been performed in order to analyse the spatiotemporal distribution of the data. Hot Spot analysis has shown to be the most comprehensive analysis, detecting the area of high impact. The Kernel density map has shown to be useful as well.

Abstract. Communities in Fiji and Tonga rely on landscape services to support a variety of livelihoods. These communities are increasingly vulnerable to climate (e.g. increasing cyclone occurrence and intensity) and environmental (e.g. mining and deforestation) stressors. Within these landscape systems, accurate and timely monitoring of human-climate-environment interactions is important to inform landscape management, land use policies, and climate-smart sustainable development. Data collection and monitoring approaches exist to capture landscape-livelihood information such as surveys, participatory GIS (PGIS), and remote sensing. However, these monitoring approaches are challenged by data collection and management burdens, timely integration of databases and data streams, aligning system requirements with local needs, and socio-technical issues associated with low-resource development contexts. Such monitoring approaches only provide static representation of livelihood-landscape interactions failing to capture the dynamic nature of vulnerabilities, and benefit only a small user base. We present a prototype of a mobile, open-source geospatial tool being collaboratively developed with the Ministries of Agriculture in Fiji and Tonga and local stakeholders, to address the above shortcomings of PGIS and other environmental monitoring and data sharing approaches. The tool is being developed using open-source mobile GIS technologies following a formal ICT for Development (ICT4D) framework. We discuss the results for each component of the ICT4D framework which involves multiple landscape stakeholders across the two Small Island Developing States. Based on the ICT4D user requirements analysis, we produced a prototype open-source mobile geospatial data collection, analysis and sharing tool. New dynamic spatial data layers related to landscape use and climate were specifically developed for use in the tool. We present the functionality of the tool alongside the results of field-testing with stakeholders in Fiji and Tonga.

Abstract. Urban designers collect information about a city or neighborhood, design improvements so that the city is functional and pleasant to live in, and communicate these improvements to relevant stakeholders. The use of space and the spatial relationships between physical features play a significant role in urban design, therefore much of the information that is collected and manipulated is georeferenced. We followed a scenario-based approach for collecting requirements for urban design projects. Functional and non-functional requirements were categorized into data collection, data storage and management, and data visualization. Subsequently, we reviewed and evaluated open source geospatial tools that can be used for the collection, storage, manipulation and visualization of geospatial data in urban design projects. Based on the evaluation, we propose an open geospatial toolbox for urban design projects. The results are equally applicable for researchers and professionals in other disciplines who collect data at the neighbourhood level.
