SARS-CoV-2 virus RNA sequence classification and geographical analysis with convolutional neural networks approach

Covid-19 infection, which spread to the whole world in December 2019 and is still active, caused more than 250 thousand deaths in the world today. Researches on this subject have been focused on analyzing the genetic structure of the virus, developing vaccines, the course of the disease, and its source. In this study, RNA sequences belonging to the SARS-CoV-2 virus are transformed into gene motifs with two basic image processing algorithms and classified with the convolutional neural network (CNN) models. The CNN models achieved an average of 98% Area Under Curve(AUC) value was achieved in RNA sequences classified as Asia, Europe, America, and Oceania. The resulting artificial neural network model was used for phylogenetic analysis of the variant of the virus isolated in Turkey. The classification results reached were compared with gene alignment values in the GISAID database, where SARS-CoV-2 virus records are kept all over the world. Our experimental results have revealed that now the detection of the geographic distribution of the virus with the CNN models might serve as an efficient method

The problems encountered in the irrigation of landscape of fethiye city center and alternative solution proposals

Bu araştırmada Fethiye ilçe merkezindeki peyzaj alanlarının sulanmasında karşılaşılan sorunlar ve alternatif çözüm önerileri belirlenmiştir. Araştırma ilçe merkezindeki dört büyük parkta yürütülmüştür. Dört parktan 0-30, 30-60 ve 60-90 cm derinliklerden alınan toprak örnekleri ile dört ay boyunca aylık olarak alınan su örneklerinin bazı fiziksel ve kimyasal analizleri yapılmış ve sonuçlar değerlendirilmiştir. Araştırma sonuçlarına göre; araştırma alanı topraklarının kumlu-tın ve kumlu-killi-tın özellikte oldukları görülmüştür. Toprakların pH değerlerinin 7,30 - 7,91, EC değerlerinin 0,85 ' 1,91 dS/m, tarla kapasitesi % 9,07 - 39,52, solma noktası % 5,28 - 25,60, hacim ağırlıkları 1,23 - 1,81 gr/cm3 arasında değişmektedir. Sulamada kullanılan sularda pH 7,5 - 8,1, EC 0,593 ' 2,929 dS/m arasında değiştiği saptanmıştır. Su örnekleri, ABD Tuzluluk Laboratuvarı Sınıflandırma sistemine göre değerlendirildiğinde Atatürk parkında C2S1, Uğur Mumcu parkında C3S1, Alparslan Türkeş parkında C3S1 ve Haluk Özsoy parkında da C3S1 sulama suyu sınıfında olduğu ve yüksek tuzlu sular kategorisinde yer aldıkları belirlenmiştir. Araştırma alanında kullanılan suların kalite açısından düşük olduğu, bununla birlikte toprakların uygun özelliklere sahip olmasının önemli bir problemle karşılaşılmamasında etken olduğu düşünülmektedir. Araştırmada, Haluk Özsoy parkında infiltrasyon testi ve buna paralel olarak örnek bir yağmurlama sulama projesi tasarlanmış ve mevcut kurulu sistemle karşılaştırılmıştır. Sonuçlar, kurulu sulama sisteminde homojen bir su uygulamasının olmadığını, yağmurlama sulamada homojenitenin sağlanmasında önemli bir parametre olan başlık debisi ve tertip aralığını belirlemek için infiltrasyon hızının ölçülmesi gerekliliğini ortaya koymuştur.Thıs research aıms to determine the problems encountered and proposed alternative solutions for the irrigation of the landscape of Fethiye city center. The research took place in four large parks of Fethiye city center. Soil samples were taken from these four parks from 0 ' 30 cm, 30 - 60 cm and 60 ' 90 cm depth, as well as water samples once every month during four months. Some physical and chemical analyses were made of all these soil and water samples and the results were evaluated. According to the results of the research, it has been seen that the characteristics of the soil of the researched area is sandy-loamy and sandy-clayey-loamy. The pH values of the soil vary between 7,30 ' 7,91; EC values between 0,85 ' 1,91 dS/m; the field capacity between 9,07 ' 39,52 % ; wilting point values between 5,28 ' 25,60 % ; bulk density values between 1,23 ' 1,81 gr/cm3. It has been determined that the pH values of the water used in irrigation vary between 7,5 ' 8,1 and EC values of the water vary between 0,593 ' 2,929 dS/m. When the water samples are evaluated according to US Salinity Laboratory Classification, it has been determined that these four parks are in the category of High Salinity Water and Atatürk Park is in C2S1, Uğur Mumcu Park is in C3S1, Alpaslan Türkeş Park is in C3S1 and Haluk Özsoy Park is in C3S1 Irrigation Water Classification. It is thought that the water used in irrigation where the research was done is of low quality; but, on the other hand, because the soil has proper characteristics, no major problem was encountered. In this research, in Haluk Özsoy Park, an infiltration test has been proposed to be taken and at the same time an irrigation system by sprinkling water has to be designed. This proposed irrigation system together with infiltration test has been compared with the existing irrigation system. The results of the research have shown that there is no homogenous irrigation implementation in the exisiting irrigation system and it is necessary to measure the velocity of infiltration in order to determine the hood flow rate and the distance between hoods. These measurements are very important parameters to obtain the homogenity in irrigation by sprinkling water

RESTful Wireless Sensor Networks

Sensor networks have diverse structures and generally employ proprietary protocols to gather useful information about the physical world. This diversity generates problems to interact with these sensors since custom APIs are needed which are tedious, error prone and have steep learning curve. In this thesis, I present RESThing, a lightweight REST framework for wireless sensor networks to ease the process of interacting with these sensors by making them accessible over the Web. I evaluate the system and show that it is feasible to support widely used and standard Web protocols in wireless sensor networks. Being able to integrate these tiny devices seamlessly into the global information medium, we can achieve the Web of Things

Norm domestication challenges for local climate actions: A lesson from Arizona, USA

Research on norm domestication in multi-level governance structures is overlooked in urban climate governance and policy literature. This paper conceptualizes multi-scalar interactions of norm domestication for local climate actions. The city of Phoenix, which operates under the “purple” (blue cities and red legislatures) state of Arizona, is analyzed to illustrate how a local government can take up the climate actions left in the void at the state and federal levels. The empirical findings reveal important temporal politics at the state level that influenced the local government's climate norm domestication. The period of Democratic party leadership diffused climate norms at the state-level and positioned the local government more as a climate policy-taker, adopting decisions from the state legislature. Swings in the state-level executive orders under the subsequent period of Republican leadership, however, forced the local government to seek some common ground for norm domestication, usually related to the nonpartisan goals of economic development. Consequently, local climate actions are subject to depoliticization of climate change from the higher-level governance structures. Overall, decarbonization targets are not being directed in ways that lead to a broader shift in the socio-technical system but would support short-term emission reductions if multiple institutions, both at the state and sub-state levels, created spaces for collaboration rather than competition.publishedVersio

Demo Abstract: Augmenting Reality with IP-based Sensor Networks

We demonstrate low-power IP-based sensor networks by showing a system that interacts with the sensor network using a RESTful web service interface. The sensor data is displayed with overlaid 3D graphics on top of a live camera feed, so-called augmented reality. The augmented reality application is built with off-the-shelf components with no sensor network-specific code. The IP-based sensor network runs the Contiki operating system
