Abstract

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.

Abstract

This article presents a process of developing a computational model of a light construction vertical lathe. The model is made using the finite elements method. Due to the complexity of the machine tool and the optimization of the computation time superelements have been used in the model. The application of this method has reduced the computation time allowing the analysis of many variants of the mutual position of the machine components. The results of the analyzes led to the indication of weak links of the machine tool. After the improvement of the machine tool construction the movement of the tool tip and the workpiece was much smaller.

Abstract

Jørn Utzon, the Danish architect genius would be 100 years old in 2018, and he passed away exactly 10 years ago. Although, he produced an unparalleled professional output (including a number of implemented projects, many not built plans and some writings) on five continents, he has remained relatively less known worldwide in general, and virtually unknown in Central and Eastern Europe in particular. The paper intends to salute his achievements with reviewing his life and professional carrier with some selected projects, including his ’brand’, his impact and some lessons for contemporary professional practice. It is largely based on my recent research that concludes in the publication of a monography, due in December 2018, in Hungary.

Abstract

In this paper we proposed to identify the optimum milling parameter required for finishing processes performed on 3Dprinted parts from ABS and PLA materials. We have identified the optimum milling parameters for a constant spindle speed of 3500 rot/min for face milling and profile contouring operations with different tools diameters. The study was performed on 3D printed specimens from ABS and PLA materials.

Abstract

With the uptake of the IoT in the industrial domain, a whole new range of cyber-physical systems has emerged; Industry 4.0 is the title given to this technological domain of highly interconnected, data-rich systems. To aid the development of such systems, a range of reference architectures has been developed throughout the years. This paper reviews a number of recent reference architectures, detailing their essential traits as well as identifying aspects that need to be further explored in order to obtain reference architectures better tuned to generating cyber-physical social systems.

Abstract

The purpose of the article is to show the practical side of reverse engineering.Many times during the process of optimizing parts, before we intervene in the tool that produces them, we want to makesure that the optimization will work in practice.For this purpose, currently, we often use 3D printers. Unfortunately, they introduce distortions of geometry to the printed prototyperesultingfrom the technology of its production.

Abstract

In this article we studies BVP’s that can not be solved as P.V.I or BVP with Matlab solvers ODExx or BVPxx since the solutions do not have limit in 0. We propose a numerical algorithm based on Cubic-spline written in Maple 16 [4].

Abstract

Apart from the strength requirements, modern lighting pole designs have to meet a number of safety requirements in the event of collisions. The paper compares the experimental tests performed at the collision test track according to EN 12767 with the results of the numerical analysis carried out in Ansys LS-DYNA. The objective of the work is to prepare a new structure of a thin-walled lighting pole of steel which minimizes absorption of the kinetic energy of the vehicle and, simultaneously, its production costs are comparable to those of a standard pole. The tests were carried out at an impact speed of 100 km/h.

Abstract

Iranian domestic tradition such as privacy and hospitality plays a significant role in shaping the Iranian traditional housing. However, studies on modern architecture have rarely focused on the house architecture, which has been adapted based on domestic tradition. The aim of this study is to understand how some features of local traditions, like privacy and hospitality, influenced housing development during the modernization period in Tehran. To this end, through a qualitative approach and data collection methods, this study identifies traditional values in modern housing. By categorizing the new house typology into detached houses, row houses, and high-rise apartments, the study discovers how architecture enables the consideration of privacy and hospitality in the physical form of modern houses. As a result, the new organization partly belonged to the traditional architecture and partly became unique as an Iranian modern house.

Abstract

This article presents the study of three-dimensional, stagnation flow of a Powell-Eyring fluid towards an off-centered rotating porous disk. A uniform injection or suction is applied through the surface of the disk. The Darcy law of porous disk for Powell-Eyring fluid is also obtained. The governing partial differential equations and their related boundary conditions are converted into ordinary differential equations by using a suitable similarity transformation. The analytical solution, of the system of equations is solved by using homotopy analysis method. The convergence region of the obtained solution is determined and plotted. The effects of rotational parameter, porosity of the medium, the characteristics of the non-Newtonian fluid and the suction or injection velocity on the velocity distributions is shown by graphical representation.
