Abstract

This paper aims to examine whether there is a direct relationship between spatial configuration and users’ behaviors in co-working spaces, and if so, how this environment and behavior relationship impacts their working process. The study employed ethnographic qualitative strategy as the general method of inquiry and used visual documentation, direct observations, and behavioral mapping as methods of data collection in two case studies. Analysis of the findings demonstrates that design elements such as barriers and fields are powerful tools for influencing and guiding users’ behavior within coworking spaces. The findings provide a deeper understanding of the relationship between design and behavioral patterns in co-working spaces. The research insights in this study may inform architects, policymakers and facility managers in making conscious decisions on the design of co-working spaces that are more meaningful to the users.

Abstract

This study examines the impact of environmental design on user experiences in the educational spaces of Tabriz Islamic Art University in Iran. In the research area, the affective assessment of four different spaces, which have been changed their function, was made. The research hypothesis is that users’ affective experience is influenced by environmental and architectural design. The method applied is the interpretation of the data obtained by the scores of the pleasure-arousal diagram of the affective and perceptional experience of 100 students in 16 educational spaces belonging to Tabriz Islamic Art University in Iran. As a result of the research, it has been verified that space design style has an active role in the affective experience of students, and there is a meaningful relationship between user’s spatial experience and the design style. In this context, it has been revealed that the spatial experiences of students in traditional spaces are positive and satisfactory in terms of interest, pleasuret and security, and that for the other three groups, many changes are required in the architectural design and spatial organization to provide positive motivation and emotional suitability.

Abstract

In this paper, the problem of tool wear prediction during milling of hard-to-cut metal matrix composite Duralcan™ was presented. The conducted research involved the measurements of acceleration of vibrations during milling with constant cutting conditions, and evaluation of the flank wear. Subsequently, the analysis of vibrations in time and frequency domain, as well as the correlation of the obtained measures with the tool wear values were conducted. The validation of tool wear diagnosis in relation to selected diagnostic measures was carried out with the use of one variable and two variables regression models, as well as with the application of artificial neural networks (ANN). The comparative analysis of the obtained results enable.

Abstract

In this paper, the authors propose a studying method for the deformation that appears before crack of ductile materials using the Lode parameter determined by the numerical calculation applied on simple models, verified in previous studies. In order to highlight the influence of the Lode parameter, the tests were performed at simple but also at compound tests. The necessity of these studies lies in the fact that the acknowledged models (the use of the integral J, the critical stress intensity factor Kc or the CPCD method) do not fully explain the phenomenon of deformation before breaking the elasto-plastic materials. The tests were imagined under the form of sets. Each set of tests was performed on smooth specimens and on specimens with a notch radius of 0.5, 2, 4 and 10 mm. Also, each set of tests was performed for pure tensile and combined tensile-torque test.

Abstract

The in service safety and reliability assurance of bridges and viaducts is determined by the choice of materials and products suitable for the design bearing solution of that construction structure. The paper proposes an operational solution for the performance characteristics assessment and verification of elastomeric bearings, which will be the basis for the consistent and coherent application of the requirements established by technical and legal regulations in the construction domain.

Abstract

Specific manufacturing technologies were applied for the fabrication of epoxy-based nanocomposites with silica nanoparticles. For dispersing the fillers in the epoxy resin special equipment such as a shear mixer and a high energy sonicator with temperature control were used. Both functionalized and unfunctionalized silica nanoparticles were added in three epoxy resins. The considered filling fraction was in most cases 0.1, 0.3 and 0.5 wt%.. The obtained nanocomposites were subjected to monotonic uniaxial and creep loading at room temperature. The static mechanical properties were not significantly improved regardless the filler percentage and type of epoxy resin. Under creep loading, by increasing the stress level, the nanocomposite with 0.1 wt% silica creeps less than all other materials. Also the creep rate is reduced by adding silica nanofillers.

Abstract

Because the requirements of the customers are more and more high related to quality, quantity, delivery times at lowest costs possible, the industry had to come with automated solutions to improve these requirements. Starting from the automated lines developed by Ford and Toyota, we have now developed automated and self-sustained working lines, which is possible nowadays-using collaborative robots. By using the knowledge management system we can improve the development of the future of this kind of area of research. This paper shows the benefits and the smartness use of the robots that are performing the manipulation activities that increases the work place ergonomically and improve the interaction between human - machine in order to assist in parallel tasks and lowering the physically human efforts.
