One of the most recent global environmental problems is noise pollution. Noise pollution is a component of environmental pollution. Like any other type of pollution, noise pollution has negative effects on environmental factors. The main sources of noise are: industry, urban areas and transport. To reduce the level of noise pollution is necessary to determine the pollution sources that cause. In this paper we will study the main areas affected by the noise pollution caused by the traffic in the city of Petrosani. We will also present solutions for reducing the pollution of the affected areas in Petrosani.
The nature of 3D ability is deeply considered, but little is known about students’ learning and understandings of technology and about the meaning to become more technologically capable. We considered the spatial intelligence of first-grade engineering students, how much that improved to the effect of 18 times 45 minutes course of computer-aided 3D modeling. We consider the success of our 3D course in spatial intelligence. According to the result of the tests, one-third of the engineer candidates has good spatial intelligence. We introduce some useful problems in 3D education; the presented problems help the students in learning how to solve technology problems, and how to design objects. We offer the intellectual pleasure of problem solving through 3D problems. Our CAD course excellently improves the spatial skills of the middle third of the students. Computer-aided 3D modeling also bridges the gap for students with worse spatial ability. Dealing with students in a more differentiated way about CAD modeling would be advisable.
As a product of native masters of the vernacular and the accumulation of thousands of years of tradition, local architecture embodies the physical and sociocultural characteristics of the environment of which it is a part. This is an indigenous architecture that displays the character of multiple and unknown local contributors and openly reflects the traditions, culture, experience and customs of the people it serves. Vernacular architecture differs according to the physical conditions of each region, becoming an expression of the culture of that area. Underlying it is the ancient wisdom, experience, skills and mastery that is transferred from generation to generation. The vernacular in architecture is the direct and unconscious translation of a society’s culture into physical substance within the framework of specified needs. It draws from tradition and with time, provides a social and cultural documentation that is passed on from one generation to the next. The aim of the study is to examine the residential works of the self-taught architect Nail Çakırhan, one of the most adamant defenders of vernacular architecture in Turkey and a recipient of the Aga Khan award in 1983, in the context of the house he built for himself using the local architectural materials of the region of Ula, where he was born, and the residential buildings he created in Akyaka, in an attempt to analyze Çakırhan’s contemporary interpretation of local architecture.
The utility model discussed in this study discloses a wood lathe balancing rest that is advantageous in terms of design, ergonomics, and functions. The study aimed to fabricate a safety device for the wood lathe machine to prevent kickback and slow down vibration from the workpiece attached to the lathe machine to avoid the vibration of the workpiece and to avoid an accident to the operator and to avoid damage of the materials. The utility model is planned not exclusively to spare time yet also for the wellbeing of the laborers amid activity. It is designed to hold the workpiece when turning and control the vibration, it can be mounted on the bed of the lathe near the center of the turning planetary.
The main objective of this work is the numerical analysis of the strength and stiffness of an annular three-layer circular plate with variable mechanical properties of the core. The plates are subjected to bending. Numerical analysis of the deflection phenomenon is carried out under different support conditions of the plate. Furthermore, the influence of the material properties of the core (linear and non-linear model) on the shear stresses and deflecions is also investigated.
Ernő Foerk and Gyula Sándy made common plans for several competitions. This study intends to show their successful cooperation as well as some of their realized buildings and awarded plans. The buildings and plans are shortly described and analyzed from the aspect of style. At the end of the study all of their common works are listed chronologically.
