This study focuses on the investigation of intelligent form-finding and vibration analysis of a triangular polyhedral tensegrity that is enclosed within a sphere and subjected to external loads. The nonlinear dynamic equations of the system are derived using the Lagrangian approach and the finite element method. The proposed form-finding approach, which is based on a basic genetic algorithm, can determine regular or irregular tensegrity shapes without dimensional constraints. Stable tensegrity STRUCTURES are generated from random configurations and based on defined constraints (nodes located on the sphere, parallelism, and area of upper and lower surfaces), and shape finding is performed using the fitness function of the genetic algorithm and multi-objective optimization goals. The genetic algorithm's efficacy in determining the shape of STRUCTURES with unpredictable configurations is evaluated in two distinct scenarios: one involving a known connection matrix and the other involving fixed or random member positions (struts and cables). The shapes obtained from the algorithm suggested in this study are validated using the force density approach, and their vibration characteristics are examined. The findings of the comparative study demonstrate the efficacy of the proposed methodology in determining the vibrational behavior of tensegrity STRUCTURES through the utilization of intelligent shape seeking techniques.

In this paper, some recent advances and a few novel concepts are presented for motion control of highrise building and bridge STRUCTURES under dynamic wind and earthquake loading. Recent research performed by the authors in the areas of smart STRUCTURES, hybrid control, tuned liquid column damper, and wavelets is reviewed.      

The HIGH-RISE building has been on the agenda of urban policymakers following the growing growthof large cities in recent years and the issue of housing shortages and efficient land use. Due to their tall stature and the number of residents, these buildings have a great impact on the performance of cities, therefore, in order to prevent their negative effects on the quality of life and satisfaction of the residents of these buildings, the location of these buildings is especially important for cities. The aim of this study is to analyze the factors influencing the satisfaction of residents of HIGH-RISE buildings that exist in the city because the measurement rate is a good guide for city managers so that if in the future HIGH-RISE building is selected as one of the strategic policies in land use. Considering the results and findings of this research, a suitable solution should be planned for this purpose. The study area of this research is the city of Gorgan and the existing HIGH-RISE buildings above20meters or seven floors are based on the comprehensive plan of the city. The research method of this study is documentary studies, survey method and questionnaire distribution. The researcher-made questionnaire included322questionnaires distributed among citizens and after collecting information, its reliability was reduced by97%using Cochran's method using Cronbach's alpha, statistical analysis was performed inferentially and descriptively in SPSS software environment and the study results showed that there are the significant relationship between Access and satisfaction levels of citizens living in HIGH-RISE buildings. The results of the hypothesis test show in both hypotheses that due to the inadequate access of the residents of HIGH-RISE buildings and the decrease in the quality of services, their level of satisfaction decreases and the residents of HIGH-RISE buildings are not satisfied with the current situation.

Probability density functions of the involved random variables are essential for the reliability-based design of offshore STRUCTURES. The objective of present research was the derivation of probability density function (PDF) for the local joint flexibility (LJF) factor, fLJF, in two-planar tubular DK-joints commonly found in jacket-type offshore STRUCTURES. A total of 162 finite element (FE) analyses were carried out on 81 FE models of DK-joints subjected to two types of axial loading. Generated FE models were validated using available experimental data, FE results, and design formulas. Based on the results of parametric FE study, a sample database was prepared for the fLJF values and density histograms were generated for respective samples based on the Freedman-Diaconis rule. Nine theoretical PDFs were fitted to the developed histograms and the maximum likelihood (ML) method was applied to evaluate the parameters of fitted PDFs. In each case, the Kolmogorov-Smirnov and chi-squared tests were used to evaluate the goodness of fit. Finally, the Inverse Gaussian model was proposed as the governing probability distribution function for the fLJF. After substituting the values of estimated parameters, two fully defined PDFs were presented for the fLJF in tubular DK-joints subjected to two types of axial loading.

In this paper we present the development from paradoxism to neutrosophy, which gave birth to neutrosophic set and logic and especially to NeutroAlgebraic STRUCTURES (or NeutroAlgebras) and AntiAlgebraic STRUCTURES (or AntiAlgebras) that are generalizations and alternatives of the classical algebraic STRUCTURES.

Urban landscape as one of the most important urban issues should always preserve its visual and aesthetic aspect. One of the most important issues that attracted the attention of urban designers is the objective of the city's objective aspect and visual disturbance. On the other hand, the geography of cities is full of high monuments and principles and criteria that have to be considered in urban planning. Therefore, the present study examines the aesthetics of aesthetics in terms of urban landscape and its impact on high - rise buildings. meanwhile, the call for highrise building measures from theorists, architecture experts and as well as residents and have been applied in order to analyze the data and data, qualitative and quantitative methods for analyzing data and data analysis, using spss statistical analysis to analyze qualitative data. The findings of this study show that in urban planning and urban planning in the geographical area of cities, it has to be applied to the design and construction of the high - rise buildings so as to help the media and the desired urban landscape. In this regard, it is recommended that the principles and rules of building a high - rise building are recommended by urban management and the ministry of planning and urbanization tailored to the features of each city. Finally, the priorities of aesthetics of urban landscape in urban geography have been mentioned.

In this paper we introduce the concept of Dirac STRUCTURES on (Hermiti an) modules and vector bundles and deduce some of their properties. Among other things we prove that there is a one to one correspondence between the set of all Dirac STRUCTURES on a (Hermitian) module and the group of all automorphisms of the module. This correspondence enables us to represent Dirac STRUCTURES on (Hermitian) modules and on vector bundles in a very suitable form and define induced Dirac STRUCTURES in a natural way.
