Abstract
A major object of prosthetics fitting procedure his to provide the amputee with the greatest potential long-term rehabilitation result by providing the finest feasible design. The foot keel and ankle joint are two key components for transtibial prosthetic users. This essay's objective is to determine the effect of systematically altering the stiffness of prosthetic foot keel and ankle joint on standing in individuals who have undergone unilateral transtibial amputations. A balance analysis was carried out to select the optimal combination of prosthetic foot and joint. According to the findings, the medium foot and soft ankle joint is the best one for standing analysis.
Abstract
The focus of this study is how Xiazhuang Village with high quality resources can achieve sustainable development in the new era by protecting and transforming vernacular architecture. Based on the layout of village, the characteristics of vernacular architecture and the ecological advantages of construction technology, this study puts forward the classification renewal and optimization design based on different buildings to solve the problems of village. Try to find a way to continue the historical context of vernacular architecture and satisfy the development of rural tourism at the same time.
Abstract
Modern buildings in Algeria consume a huge amount of energy and deliver modest thermal comfort, due to their design which does not address the local climate conditions. In contrast, it is commonly recognized that vernacular architecture is climate-responsive and environmentally friendly architecture.
This study aims to assess the thermal performance of vernacular architecture in the hot and dry climate of the Ziban region, Biskra. It was achieved by describing the main passive strategies in this architecture, later performing field hygrothermal measurements on two different houses in this region. The results revealed that the thermal effectiveness of these vernacular houses depends on the interaction of all their vernacular passive strategies from architectural to urban scale.
Abstract
The urban structure of Dombóvár has been transformed in recent centuries, and the protected buildings that once defined the town center, have been relegated to the periphery. Today, despite its rich architectural heritage, the Kakasdomb district is an area at risk of segregation. The key to the integration of the district into the existing urban tissue is the utilization of the protected buildings of the area including the former synagogue building. This paper examines the possibilities for the reuse of the synagogue based on the town development strategy and the perceptions of the remaining Jewish community, and the systematic modification of the settlement structure, together with the possibilities for the integration of the neighborhood.
Abstract
In this work, the actual aspect of the creation of comfortable climatic conditions indoors due to the compressed swirl compact air streams at an alternating mode is considered. The purpose of this article is the mathematical modeling of the swirl compact air jet and getting of the analytical equations for calculation air distribution in a premise at the condition of dynamic indoor climate in compressed conditions of a premise for providing comfort people well-being. A mathematical model of air supply with the swirl compact air jets in the room has been developed. A combinatorial-logarithmic method for the graphs approximating the dependence of the relative transverse velocity of a swirl compact air jet and the correction coefficient for compression and swirling on the relative transverse coordinate has been developed.
Abstract
For the final quality of the part, metal forming trends are depending on improvements of friction and tribology. As a consequence, there is a trend in which tribology and friction are becoming increasingly important for correctly replicating the forming simulation of those parts. The objective of this work was to improve the forming simulation of an automotive shell part on AutoForm. The part was provided by a vehicle industry supplier. Enhanced Coulomb models consider a change on friction coefficient due to different factors, better approximating the description of friction to reality. For the current study, pressure and velocity dependent friction models were chosen as long as the combination of both. The virtual tribology was simulated using the software TriboForm. Velocity dependent friction model and the virtual tribology have shown similar results with expected lower coefficients of friction.
Abstract
Nowadays, due to savings requirements, the heights of floor systems in multi-story buildings are reduced. To ensure passage of installation within a floor depth, a solution considering web openings is usually adopted in steel-concrete composite structures. Owing to the presence of web openings, the structural performance of a bearing member is affected not only in the final stage but also during the construction. Hence, the main purpose of this research is to evaluate the impact of web openings on the lateral-torsional buckling resistance of the steel part of composite girder in the erection stage. Comparison of lateral-torsional resistance of the steel girders with web openings derived by the analytical approach with results obtained by numerical model is presented and discussed.
Abstract
Vehicle manufacturing is an industry in which the technologies used by Industry 4.0 and their evolution can best be traced. Digitalization-robotization is paramount to the technical methods used in the Fourth Industrial Revolution. The question is how close a correlation between productivity and digitalization robotics in vehicle production is in the Member States of the European Union. I perform the relationship between the two variables by correlation calculation. Then I classify the member states according to the closeness of the relationship between the two variables using the method of hierarchical cluster analysis. Empirical results show a robust relationship, with the highest per capita production value in those Member States with the highest degree of digitalization-robotization in vehicle production. In conclusion, the countries in Central and Eastern Europe and the end of the productivity rankings need to increase the degree of digitalization of their vehicle production to increase their productivity and competitiveness.
Abstract
The work is devoted to study of thermal efficiency of heating convectors with aluminum ribbing to ensure comfortable indoor conditions. The purpose of this paper is to evaluate theoretically and experimentally the thermal efficiency of convector-type heaters with aluminum ribbing, to implement numerical simulation and to obtain dependencies for determination of thermal characteristics of convector-type heaters with aluminum ribbing, ensuring of a proper both indoor climate in the premise and energy saving. A nomogram of interdependence between heat amount, heat carrying medium flow rate, the initial and final temperatures was created. Heat quantity increases with increasing heat carrying medium flow rate, the inlet temperature and decreases with increasing of the exit temperature.
Abstract
With the gradual improvement of urban construction, more and more experts and the public realized that the speed of urban development be reasonable, which caused urban regeneration to turn to a new-minded “urban micro-regeneration”. “Micro-regeneration” is an extension of the concept to the direction of urban construction. The concept of micro-regeneration was first applied to the regeneration of individual buildings in the old city. The research on the intervention of public art in urban micro-regeneration is still in its infancy in China. Based on practice, this paper explores the possibility of public art's intervention in urban micro-regeneration.
