Analyzing metaheuristic methods to build an optimal composite foot prosthesis insole

This paper uses metaheuristic algorithms to develop and optimize composite materials. To calculate the characteristics that allow the planned item to withstand particular loads, ABC and Differential Evolution algorithms are utilized. One of the key challenges in these designs is determining the piece's thickness. Designing a carbon fibre insole for Latin American users will improve the design process by generating functional solutions that are feasible to manufacture and in less time than traditional design methods. The results reported in this work demonstrate that a functional design may be developed, validated by finite element method, with minimal material waste and in a reasonable period.

Some aspects of sustainable urban planning using environmental solutions

The ecological aspect of urbanization is reflected in the fact that cities are increasingly concentrating all types of environmental pollution, which become serious problems of the deteriorating of people living conditions. In the Future megalopolises more than 70% of the population will live in the next few decades according to the UN report. It is necessary to make all conditions for the ideas implementation of comfortable and safe cities. Research and innovation of ecological solutions for eco-cities includes four directions. The article discusses one of them, it is the Enhancing the sustainable urbanization, its classification, which include the sustainable Urban Planning with the Sustainable Drainage System (SuDS) approach. The article provides functions and advantages of SuDS systems. Particular attention is paid to the zones of forgotten urban spaces. These zones can improve business and residential areas, as multi-functional design with nature can create new dynamic spaces that increase property values, thereby attracting investors, improving citizens’ well-being. The article provides some examples of draft designs for the improvement of the coastal zones of the Yeltsovka-2 River, located in the area of Zaeltsovsky Park.

Performance of Flushing Efficiency of Sediment Evacuation from Wlingi and Lodoyo Reservoirs

The sediment evacuation from the reservoir should be carried out when it disturbs the dam development’s functional design. There are issues regarding the objection to releasing sediment from the reservoir, especially related to potential environmental degradation of the river downstream. The sediment source entering the reservoirs is considerably variable, depending upon the catchment characteristics and the hydrological triggers. When limiting the erosion yield and controlling the sediment in the catchment, evacuating sediment from the reservoir could be the only alternative to avoid environmental degradation. Several issues showed that sediment evacuation from reservoirs is a cost-effective solution. Therefore, assessing the efficiency of sediment evacuation from a reservoir through flushing has become of high interest. This paper presents the analysis of the flushing efficiency performance of the flushing operation of Wlingi and Lodoyo Reservoir that was carried out on 10-17 March 2019. The flushing efficiencies are found to be 0.005 and 0.003 for Wlingi and Lodoyo Reservoirs, respectively. These figures are lower than that of Mrica Reservoir and other world reservoirs at higher than 0.1. Further analysis suggests the critical timing of the sediment evacuation schedule considering the inflow condition.

Final design of the ITER bolometer first plasma component: cable installation template

The ITER bolometer cable installation template is a first plasma component which main function is to provide a temporary fixation of the mineral insulated cables and to protect them through first plasma operation inside the vacuum vessel until the final bolometer cameras are installed in the second assembly phase. In this paper, the final design of the cable installation template will be presented, the assembly procedures and important functional design details in order to be compliant with its interfaces, the vacuum vessel, the flux loops, the electrical services, the first plasma components and the assembly. Requirements that drive the design will be explained, along with the technical solutions chosen to fulfill them. Important sub-components will be presented in more detail, such as the boss fixation, which will compensate geometrical uncertainties of the as-built boss positioning, as well as the mineral insulated cable holder, which will prepare the electrical termination and facilitate the installation of final vacuum vessel cameras during the second assembly phase of ITER. Additionally, the step-by-step assembly plan agreed with the team of ITER machine assembly and tooling will be described. A custom developed boss welding tool will be described as well. The system load specifications applicable for this first plasma component will be presented as well and an overview of the structural integrity analysis report will be given. It will be shown that most loads on the component are very limited and there is no risk of structural failure or loss of relevant system functions. The paper concludes with a summary of the work and an overview of the procurement and delivery status to ITER.

A METHODOLOGICAL FRAMEWORK FOR RESEARCH OF ERGONOMIC RISK FACTORS IN DENTISTRY

This paper proposes a methodological framework for the research of ergonomic risk factors in dentistry, since this is a profession with very specific and complex ergonomic challenges. When analyzing ergonomic risk factors in dental practice, three separate entities should be taken into account: the dentist, as the central figure in the office; the dental office equipment, which includes all the instruments and devices, dental chair and dentist stool; and the dental office, including the workplace layout and the working conditions. Bearing in mind that it is impossible to eliminate the risk, systematic analysis of ergonomic risk factors enabled us to propose solutions for its reduction. Risk reduction improves dentists’ work ability and working conditions in the dental office and contributes to a more humane, i.e., more functional design of dental equipment.

Research on the Application of Interaction Design in the Functional Design of Intelligent-home Products

The networking operation of intelligent-home products can expand more functions and bring consumers more in-depth interactive experience. The effective integration of interaction design, intelligence and info tech in intelligent-home products can effectively solve the shortcomings and problems of home market products. Based on this, this paper first analyses the concept and value of product functional interaction design, then studies the functional design of intelligent-home products based on interaction design, and finally gives the utilization strategy of interactive design in the functional design of intelligent-home products.

Reclamation and development of post-industrial sites for recreation as exemplified by projects carried out in Poland in the 1920s and 1950s

The aim of this article is to present spectacular examples of reclamation and development of post-industrial sites, carried out in Poland in the 1920s and 1950s, with emphasis on their recreational function. Examples include a park built between 1889 and 1920 by Wojciech Bednarski in the valley of the former quarry in Podgórze, now the right-bank district of Krakow, and “General Jerzy Ziętek Provincial Park of Culture and Recreation”, now called “the Silesia Park”, created in the 1950s on degraded post-industrial land located within the borders of three cities: Chorzów, Katowice and Siemianowice Śląskie. Both parks are examples of reclaiming brownfield sites for recreational use in order to create attractive leisure spaces. They have become a model and point of reference for other park planning projects in Poland. Their spatial and functional design is exceptionally timeless. The study is mainly based on a review of the literature of the subject.
