Planning and designing livable recreational open spaces in developing countries. Insights from Souk Ahras City, Algeria
Get PDFCreating livable recreational public open spaces is essential for urban quality of life and well-being. In the Algerian context, the topic of public open spaces has been extensively investigated. However, little research has examined how spatial and physical attributes of recreational open spaces influence their use and perceptions by residents. This study investigated the role of urban planning and urban design in shaping livable recreational open spaces in Souk Ahras City, Algeria. The study used a mixed-methods approach: spatial analysis was used to map five typologies, while a survey among 426 residents was used to assess the residents’ satisfaction, use, and perception of recreational open spaces. Although several recreational spaces have been, their availability was insufficient. In addition, satisfaction levels with the spatial and physical attributes of recreational open spaces were mainly average to low. Moreover, satisfaction was positively correlated to use frequency, duration, and favorable perception, highlighting the importance of the design quality of those spaces. However, satisfaction did not predict activities undertaken, underscoring the need for considering more than just the physical aspect when new recreational open spaces are proposed. Recommendations include increasing provision and improving spatial and physical attributes. The findings provide empirical insight to guide context-specific interventions for improving developing cities’ recreational open spaces. Further research should examine interactions between space, culture, and policy across multiple developing cities
KAJI NUMERIK GROUND PAD SHOE KENDARAAN TEMPUR DENGAN MODEL MATERIAL HYPERELASTIC
Get PDFOne of the important components on a combat vehicle is the ground pad shoe (GPS) or track pad. GPS that has been developed at this time mostly uses rubber material. Rubber raw materials themselves are found in Indonesia in large amount. Indonesia left 3 million tonnes of natural rubber unprocessed in 2018. On the other hand, natural rubber research is quite expensive and takes a long time to become a product. To make rubber products is needed special molds and tests. To solve the high costs and long time involved in rubber research, it is necessary to carry out numerical research. In this study, a numerical study of GPS rubber for combat vehicles was carried out with a hyperelastic material model. The research was conducted experimentally and numerically. Tensile testing is carried out on imported GPS samples which are then used as comparison data for numerical studies. The Mooney-Rivlin, Neo-Hookean, Yeoh, and Ogden hyperelastic models were varied to get the stress and strain values closest to the experimental test. The results of the numerical study show that the best hyperelastic model for the imported GPS rubber model is the Neo-Hookean model. The tensile strength of GPS according to the experimental tensile test results is 16.93 MPa, while the result of the finite element method (FEM) is 16.75 MPa. The GPS modulus 200% according to the experimental tensile test results is 14.7 mm/mm, while the FEM result is 15.3 mm/mm. The difference between the FEM and experimental test values for tensile strength and modulus 200% are below 5%. Maximum stress on GPS is 4,4 MPa and safety factor 3,8.One of the important components on a combat vehicle is the ground pad shoe (GPS) or track pad.

Factual Analysis of Factors Influencing Consumer Cognitive Thinking and Automobile Designing using Fuzzy-AHP
Get PDFConsumer cognitive and emotional responses significantly impact consumers’ affinity for both tangible and intangible products. Recent research underscores the heightened influence of consumer emotional and cognitive perceptions in product design, surpassing reliance on designers’ instincts or experiences. This case study delved into the analysis of automobiles, using cars as focal product. While visual elements like curve lines, grill design, and color predominantly shape consumer perspectives, non-visual factors such as reliability, quality, and ergonomics play a pivotal role in purchasing decisions. Our investigation, involving six industrial experts and over 130 participants, explored non-visual factors affecting consumers’ cognitive perceptions during car purchasing. Through a two-phase experimental approach, we developed a framework to understand the disparities in ranking assigned by consumers and designers to these non-visual factors, revealing perception gaps. Utilizing the rank value methodology, the Pareto principle, and Fuzzy-AHP analysis, we identified mileage/fuel efficiency, safety features, and reliability as dominant factors influencing consumer perceptions. Designers, on the other hand, prioritize safety features, reliability, and quality/warranty. Our findings emphasize the strategic significance for automobile companies to enhance their success rates by prioritizing these key factors, ultimately elevating brand value, profile, and overall financial prosperity
