TL;DR: In this paper, the relationship between water body scale and climate parameters like wind speed, air temperature, relative humidity, as well as thermal comfort index was modeled and analyzed via Envi-met code.
Abstract: The relationship between water body (fountains) scale and climate parameters like wind speed, air temperature, relative humidity, as well as thermal comfort index was modeled and analyzed via Envi-met code. Taking the water impact and factors analysis as a research object, the factors mainly discussed in this research are square area to water-body area ratio and the location of the water element. However, the computational fluid dynamics simulations were conducted on the following scenarios: 3% (original base case), 6%, and 9% of the total square’s area, then the outputs of the two simulation results were compared to the original base case. The results revealed that water scale has a slight effect on the micro-climate of the built environment in the summertime in moderately warm-wet climate zone. However, it is beneficial to adjust
temperature and humidity in public spaces of central European cities. Nonetheless, the main aim of this paper is to quantitatively investigate the impact of the water bodies on the urban weather parameters and human thermal comfort under the influence of different scale ratios in Pecs-Hungary.

TL;DR: In this paper, the authors defined the operation of Gabcikovo Project as a complex multi-criteria optimization task with many technological, water management, energetic and environmental constrains.
Abstract: Task of shipping operations control of the Gabcikovo Project is to synchronize several requirements. These come from versatility of GAP and must meet with the following goals. The operation of GAP must be effective (maximization of the ship locks capacity, maximization of income from electricity production in hydropower plant); reliability of operation of the ship locks must not be limited or endangered by defects on technology parts of the ship locks caused by illegal parameters of water flow in the filling and emptying system; and shipping safety must not be endangered or limited by unsuitable parameters of river way (navigable depth below minimal shipping depths in ford sections caused by flow changes on Gabcikovo Project and ships crushing into riverbed of the Danube river). By taking these goals into account, it is possible, in general, to define operation of Gabcikovo Project as complex multi-criteria optimization task with many technological, water management, energetic and environmental constrains...

TL;DR: In this paper, a computer-based tool is used to quantitatively study the outdoor thermal comfort and its weather parameters and the results have shown that the average predicted mean vote value is +4 (very hot), the average air temperature is hot, the average wind speed is light breeze and the relative humidity falls within the comfort range.
Abstract:
Numerical research in the context of urban in a humid continental climate zone is still limited. The aim of modeling the case study is to assess the performance of outdoor thermal comfort parameters and investigate their capabilities in achieving the outdoor thermal comfort. A computer-based tool is used to quantitatively study the outdoor thermal comfort and its weather parameters. The parameters have been analyzed using ENVI-met tool and then compared against different comfort scales like relative humidity comfort scale, the predicted mean vote scale as well as other scales and standards. The results have shown that the average predicted mean vote value is +4 (very hot), the average air temperature is hot, the average wind speed is light breeze and the relative humidity falls within the comfort range. However, street orientation, shading, water bodies and plantation play a significant role in increasing and decreasing the outdoor thermal comfort.
TL;DR: In this paper, the authors focused on improving the cooling energy consumption of the contemporary buildings in Biskra City, Algeria, using dynamic simulation with Vi-Suite add-on Blender 3D software.
Abstract: The building facade becomes an integral part of the concept for adaptation of the building to the climate conditions; it should be able to respond and adapt its properties and components with the immediate environment. In the hot and dry climate in Algeria, the contemporary building design, materials, and techniques applied do not properly address the local climate conditions and the final energy consumption. Contrary to this, in traditional building practice, the local materials and passive strategies are used, which responded to the environmental context. This study is focused on improvement of the cooling energy consumption of the contemporary buildings in Biskra City, Algeria. The traditional climatic facade solutions are investigated in order to adapt them to the contemporary buildings. To define and optimize the solutions, dynamic simulation with Vi-Suite add-on Blender 3D software was used. The results show a significant reduction in the cooling energy consumption, which confirms the use of the tra...

And the characterization of aluminum composites on the aspects and phenomena of the distribution effect of pressing effect in the case where the temperatures were higher than recrystallization value.
Abstract: The pressing of equal channel angular pressing - parallel channel process has an effect on microstructure and mechanical properties of the composite materials. Finite element has been used for conducting pressure effect through parallel channel for knowing distribution effect pressing. The materials AA1070 and AA6061 powder matrix composite with Al2O3 nano fiber were used as reinforcement. Mechanical properties and scanning electron microscope were observed in room temperature pressure and in case where the temperatures were higher than recrystallization value. Both results were compared to determine the effectiveness of pressure on each process. The characterization of aluminum composites on the aspects and phenomena of the distribution of pressing effect on hot and cold conditions treasured by finite elements will be explained in this paper.

TL;DR: In this article, a village project in Xinglong is examined, where development was strongly connected with tradition, and methods initiated to develop village tourism, and the direction of the village construction can be shown and further developed and the revival of rural areas can be realized.
Abstract: The ‘Beautiful China’ project originated from the Chinese central government for the purpose of correcting the imbalance between urban and rural areas. In response to this national policy, numerous positive village development projects focus on improving the tourism potential of the Hebei province, North China. Because most of these rural areas lack historical heritage and infrastructure to support tourism, a well-directed architecture and landscape design initiative was organized by local governments. This is to create new types of livable, humanized, high standard and attractive villages through good design. A village project in Xinglong is examined, where development was strongly connected with tradition, and methods initiated to develop village tourism. In this way, the direction of the village construction can be shown and further developed and the revival of rural areas can be realized.
TL;DR: In this article, the state of the art of the radioactive waste glass corrosion in the circumstances of deep geological disposal were extensively studied, focusing on the role of the iron carbonates (ankerite), which already exists in the clay structure of the disposal depth.
Abstract: Iron corrosion products of the steel canister in the nuclear waste container are highly silica sorptive materials and very much expected to delay formation of the protective layer (gel) on the nuclear glass interface. This study is focusing on the role of the iron carbonates (ankerite), which is probably one of iron corrosion products and already exists in the clay structure of the disposal depth. French SON68 inactive reference glass (alternative to the R7T7- type) samples are planned to leach in different series of experimental models with dissimilar quantities of natural ankerite. All batch experiments will be cultivated in synthetic Callovo-Oxfordian groundwater; where different pH (4-9) values and temperatures (35, 50, 90 °C) are considered. In this paper the state of the art of the radioactive waste glass corrosion in the circumstances of deep geological disposal were extensively studied.

TL;DR: In this article, a model representation for the future planning of facades is developed for new and the existing building, which can be used to derive new characteristics for new facade design.
Abstract: In recent years, surfaces of plaster facades increasingly have been covered with algae. This effect is reinforced by improved thermal insulation of the building. Envelope e.g. due to the use of plastics, as well as the climate change and lower air pollution. The accumulation of condensation water is therefore of decisive importance. So far, the amount of condensation water was determined with static weight methods. New developments in material research attempt to illustrate the susceptibility to condensation with different measurement methods. The differences can be seen in various systems and materials. Developing a model representation for the future planning of facades is thus possible for new and the existing building. This model can be used to derive new characteristics for new facade design.
