The use of unmanned aerial vehicle (UAV) data in village development plans: a case study of Aksaray Yaylak Village
(Mersin University, 2022) Yılmaz, Hacı Murat; Aktan, Nusret; Çolak, Adem; Alptekin, Aydın
With the increasing population, the problem of people's need for shelter has also emerged. In many settlements, structures were built without the necessary planning. Three-dimensional (3D) models of these lands should be created in order to make land management plans. Technological improvements in remote sensing have made easier the terrain modelling. To make a better land management plan of rural areas, we need high resolution maps. Unmanned aerial vehicle (UAV) is one of the methods in map production, which can obtain spatial data with high accuracy. In this study, we created 3D model of Yaylak village located in Aksaray District using UAV Photogrammetry. We created high resolution Digital Surface Map and orthophoto map of the village using the pictures obtained from e-Bee. Using these maps, the administrator of the region will decide healthy decision. This study shows us UAV can be used in preparing the necessary maps for designing the settlement area.
Effect of heat treatment on the mechanical properties and corrosion behaviour of Al–Si–Mg alloy systems
(Pleiades Publishing, 2022) Kaygısız, Yusuf; Balun Kayan, Didem
Abstract: In this study, effects of heat treatment on microstructure, hardness and corrosion behaviour of Al based eutectic alloy systems directionally solidified at different growth rates were investigated. The compositions of alloys were selected as Al–12.95 wt % Si–4.96 wt % Mg and Al–13 wt % Mg2Si. Al–12.95 wt % Si–4.96 wt % Mg and Al–13 wt % Mg2Si alloys were kept at 500 and 540°C for 2 h, respectively, then quenched in cold water and subsequently artificially aged at 180°C for 4 h. The microstructure of Al–12.95 wt % Si–4.96 wt % Mg eutectic alloy consists of irregular Si plates and Mg2Si Chinese script in an aluminium matrix, while the microstructure of Al–13 wt % Mg2Si pseudoeutectic alloy consists of Mg2Si Chinese script in an aluminium matrix phase. Hardness value increased from 83.7 ± 2.0 mm–2 to 125.3 ± 5.2 kg mm–2 and from 82.5 ± 1.0 to 121 ± 2.0 kg mm–2 with the effect of the growth rate and solution heat treatment for Al–12.95 wt % Si–4.96 wt % Mg and Al–13 wt % Mg2Si alloy, respectively. Corrosion behaviour of the samples were investigated by Tafel polarization curves and electrochemical impedance spectroscopy (EIS) techniques. The increasing solidification rate of the alloys and also the heat treatment process increased their corrosion resistance.
The deformation characteristics of buried HDPE transfer lines in trenches under the effect of temperature
(Pontificia Universidad Catolica de Chile, Escuela de Construccion Civil, 2021) Polat, Necmettin; Erenson, Can; Terzi, Niyazi Uğur
Today, the use of high-density polyethylene (HDPE) transfer lines is increasing day by day for drinking water, wastewater, sewerage networks, rainwater drainage lines, water transport structures, and natural energy sources, etc. In this study, flexible HDPE pipes were embedded in a trench to expose them to variable relative density and different thermal conditions so that the resulting deformation behavior could be investigated. Displacements and elastic strain values in the crown and spring line regions were measured. The main aim of this research was to determine the behavior of HDPE pipes under temperature effects within the framework of geotechnical principles to reflect real field conditions. As a result, pipes subject to vertical loading were tested under different relative density and thermal conditions. In the experiments carried out in a silica sandy trench, the deformations increased due to an increase in relative density. The maximum displacements and bending moment values were obtained at 50°C, which was the maximum thermal condition applied. An increase in temperature increased the deformation values due to the resulting decrease in the modulus of elasticity.
International versus domestic?: the question of the applicability of intellectual property law to the CISG
(Taylor and Francis, 2021) Kiraz, Şerife Esra
As a result of the increase in trade over intellectual property (IP)-related goods, the risk of encountering intellectual property rights (IPRs) infringement occurs. When a third party’s IPRs are infringed, the buyer of such goods can be prevented from using or reselling the goods in question according to IP law. Article 42 of the United Nations Convention on Contracts for the International Sale of Goods (CISG) covers these situations and obliges the seller to ‘deliver goods which are free from any right or claim of a third party based on industrial property or other intellectual property’. However, there is no definition of ‘industrial property or other intellectual property’ either within the wording of Article 42 or the scope of the CISG. This chapter questions whether the international IP agreements and IP rules of domestic law where the claim is raised should be applied in Art 42 CISG cases to examine the existence of third-party IPRs over the goods purchased by the buyer. Although the CISG should be interpreted regarding its international character, I argue that any IPRs or claims should be examined according to the law under which the right or claim has been raised.
The global economy during covid-19 pandemic: realizations and predictions
(Peter Lang AG, 2021) Sever, Erşan; Ay, Merve
The COVID-19 crisis, which has been severely hitting the world economy for more than a year, has left the whole world to deal with first health, then economic, and lastly social problems. In that regard, the COVID-19 crisis has outpaced the 1929 Depression, which was the biggest contraction in the world economic history. This study discusses the macroeconomic effects of the COVID-19 outbreak on the global economy. In this context, we discuss the mechanisms by which a pandemic in the health field slows down the functioning of the economy. Then, we analyze the effects of the crisis on households. The effects of the pandemic are discussed in a group of countries that differ according to their level of development. Struggling with the COVID-19 crisis, all countries have intervened in the market through monetary and financial instruments. Countries’ monetary policy decisions affect other countries’ macroeconomic outlook. Therefore, in this study, the monetary and fiscal policy decisions taken by country groups during the pandemic are discussed according to their development levels. With the increasing spread of the pandemic, supply and demand shocks are seen within countries and thus economic contractions occur. Since this contraction influences all large and narrow scale businesses within a short period, the companies dismissed workers which resulted in an alarming increase in unemployment rates all over the world. With the weakening of international trade in this process, the world economy has experienced a recession that cannot be recovered for many years.
