Product Recommendation for C2c Marketplace With Collaborative Filtering Als Algorithm
No full textIn this project, a machine learning recommendation model is created for an e-commerce company which runs a customer to customer business. The raw data consisted order reviews, order details, product like event information and product details. The explicit and implicit feedbacks are used together and a rating generation logic per user-product couple is applied to create the source data of the model by using Google Cloud BigQuery tool. The ALS algorithm which uses matrix factorization is applied for predicting the top items which have highest ratings for each user. PySpark which is Apache Spark’s python API is used for implementing the ALS model. The best hyperparameters are determined comparing the root mean square error results by using grid search and cross validation and 0.78 of RMSE is reached. The predictions for the empty ratings are sorted then top rated 10 products are taken as recommendations. The evaluation of the model is done by comparing those recommendations with the user preferences. The user preferences are specified by using averagely top rated product categories and most interacted product categories in count. The recommendations are observed to be consistent with the user preferences
İnternet sitesi tarayıcısı, sayfa yoğunluk, arama yoğunluk kontrollü ve benzer sayfa denetleyicisi ile arama motoru optimizasyon aracı
No full textFor this project, I built an SEO tool. I am working in digital marketing, and we are using various tools, and services frequently. But due to budget constraints or a variety of tools, we cannot reach each tool all the time. Even these tools are not easy to reach, some of their features are fundamental for jobs we are handling every day. Therefore, we needed to find their free / less expensive versions or use them within their free limits. But since I learned some coding and saw programming possibilities, I see that some must-have features are not that hard to code or complicated. Therefore, I created a small program to help my career and my budget. This script helps generally SEO reporting.This script has 4 main features. Web crawler feature can crawl the website and provide website’s page details. Page density checker feature can report the word density of the page. Search density checker searches the input query on Google, reports top 10 results and their word density. Finally similar page checker crawls the website and runs cosine similarity test for each page of the website
Development of a New Solar, Gasification and Fuel Cell Based Integrated Plant
No full textDespite its shortcomings, fossil-based fuels are still utilized as the main energy source, accounting for about 80% of the world's total energy supply with about one-third of which comes from coal. However, conventional coal-fired power plants emit relatively higher amounts of greenhouse gases, and the derivatives of air pollutants, which necessitates the integration of environmentally benign technologies into the conventional power plants. In the current study, a H2–CO synthesis gas fueled solid oxide fuel cell (SOFC) is integrated to the coal-fired combined cycle along with a concentrated solar energy system for the purpose of promoting the cleaner energy applications in the fossil fuel-based power plants. The underlying motivation of the present study is to propose a novel design for a conventional coal-fired combined cycle without altering its main infrastructure to make its environmentally hazardous nature more ecofriendly. The proposed SOFC integrated coal-fired combined cycle is modeled thermodynamically for different types of coals, namely pet coke, Powder River Basin (PRB) coal, lignite and anthracite using the Engineering Equation Solver (EES) and the Ebsilon software packages. The current results show that the designed hybrid energy system provide higher performance with higher energy and exergy efficiencies ranging from 70.6% to 72.7% energetically and from 35.5% to 43.8% exergetically. In addition, carbon dioxide emissions are reduced varying between 18.31 kg/s and 30.09 kg/s depending on the selected coal type, under the assumption of 10 kg per second fuel inlet
Untangling the Relationship Between Internalized Heterosexism and Psychological Intimate Partner Violence Perpetration: a Comparative Study of Lesbians and Bisexual Women in Turkey and Denmark
No full textPsychological intimate partner violence (IPV) perpetration is not limited to heterosexual relationships and can affect all genders and sexual orientations, including lesbians and bisexual women (LB) both in Denmark and Turkey. Internalized heterosexism might be one of the factors increasing the risk of LB's use of psychological IPV perpetration. However, it is still unclear how being LB in Turkey and Denmark interact in the internalized heterosexism and psychological IPV perpetration relationship. The current study, therefore, presents an investigation of (a) the prevalence of sexual orientation (LB) and country (Denmark and Turkey) differences in perpetrating psychological IPV and (b) the moderating roles of sexual orientation and country on the association between internalized heterosexism and psychological IPV perpetration. A sample of 449 LB from Denmark and Turkey completed the Lesbian Internalized Homophobia Scale and the Multidimensional Measure of Emotional Abuse Scale. The results of chi-square analyses indicated that LB from Turkey and bisexual women from both countries reported significantly higher psychological IPV perpetration. The results of moderation analyses revealed that country had direct effects on the use of psychological IPV perpetration. No moderation effects were found for both sexual orientation and country in three of the four types of psychological IPV perpetration. These findings suggest that LB are not an exception to the perpetration of IPV. Furthermore, the findings were discussed from the perspectives of intersectionality and minority stress
The Influence of Internalized Heterosexism on Life Satisfaction: Comparing Sexual Minority Women in Belgium and Turkey
No full textTo date, the majority of research studying lesbian, gay, bisexual, transgender, and queer (LGBTQ) health has been conducted in Westernized, predominantly individualistic countries. Building on minority stress theory and models of LGBTQ health, we explored how sexual orientation and nationality moderated the association between internalized heterosexism and life satisfaction for lesbian and bisexual (LB) women living in two countries (Turkey and Belgium) with contrasting social contexts. The results of two-way MANOVA, in a sample of 339 Turkish and 220 Belgian LB women, revealed main effects but no interaction effects. LB women in Belgium reported less internalized heterosexism and more life satisfaction than LB women in Turkey. The results of moderation analyses indicated no moderation effect, however internalized heterosexism and country emerged as the best predictors of life satisfaction. Findings were interpreted with a focus on how culture-specific aspects contribute to life satisfaction among LB women. Our findings suggest mental health professionals working with LB women need to tailor therapeutic interventions to reflect the social context connected to their patients’ nationality, in order to effectively address internalized heterosexism, improve life satisfaction, and promote self- and social advocacy. Cultural values, such as adherence to collectivistic or individualistic norms, should be included as variables in future research examining determinants of LGBTQ health

Bert tabanlı gramer analizinin Google arama sonuçlarındaki etkisi
No full textThis study aims to study the BERT, namely Bidirectional Encoder Representations from Transformers model, which is introduced by Google and is of great importance in content analysis, and to examine the role of grammatical accuracy in the process of content quality measurement and Search Engine Results Pages (SERP). BERT has an important role among the algorithms used by Google in order to maintain the quality of search results and to provide more relevant content to users by understanding the content more effectively.In this study, CoLA data, which is accepted as the most reliable data in this field and therefore used frequently in similar BERT studies, is used. The main purpose here is to make a BERT-based grammatical evaluation of sentences in a content and then examine these results on pages with optimal ranking values, to examine the connection between search results and grammatical accuracy and the importance of this parameter.In this context, the project consists of two phases. In the first phase, the content of the pages that are visible in the first 20 in 50 different queries are scored with the pre-trained BERT model. In the second phase, a dataset that includes different SEO-focused metrics of the same pages is created manually, and the importance of the BERT score among these features is investigated

Milletlerarası Özel Hukukta Ticari Şirketlerde Birleşmeler ve Devralmalar
No full textIn this thesis, international commercial company mergers and acquisitions, starting from the pre-contracts period, the establishment of contracts, the competence of the parties, the form of the contracts, the resolution of the conflict of laws regarding the transactions of the contracts, the situations where the freedom of will is possible in the contracts and the possible disputes arising from such contracts. The dispute resolution ways that can be put in the authorization agreement for resolution have been examined. In addition, regarding the cases where Turkish law is applied to the contractual transactions, Turkish law has been mostly compared with EU Law. Company mergers and acquisitions are transactions with a different structure. For this reason, both concepts should be dealt with in all aspects economically and legally and their differences should be revealed. Because although the merger and acquisition transactions are legal transactions, it is possible to say that their causes and consequences are economic. Although the concept of acquisition is used as a type of merger in the TCC, it should actually be understood as taking control of a company, unlike the merger. In the merger process, the transferred company or companies joined the acquiring or newly established company without liquidation, but in the acquisition of the company, the target company acquired continues its existence and only the real or legal persons that control it change. In addition, the partners of the company transferred in the merger process become the shareholders of the acquiring company in return for the company shares in accordance with the principle of continuity of the partnership and as a general rule there is no payment of any price, in the takeover transaction, a price is paid in return for the transfer and at the rate of the share transferred by the partners in return for this price, Property rights regarding the company subject to the transaction expire with the transfer. Both international qualified contracts have common aspects such as a letter of intent, due diligence, and confidentiality agreement before the establishment stage. But because transactions have different legal structure and subject matter, they have quite different qualities from each other in terms of establishing a contract, determining the law to be applied in accordance with the rules of conflict of laws, and applying the freedom of Will to the contract. For the effective and practical resolution of disputes arising from both transactions, dispute resolution methods, especially arbitration, that can be put into authorization agreements are the issues that need to be emphasized.Bu tez çalışmasında, uluslararası nitelikteki ticari şirketlerin birleşme ve devralma işlemlerinin, sözleşmeler öncesi dönemden başlamak üzere, sözleşmelerin kurulması, tarafların ehliyeti, sözleşmelerin şekli, sözleşmelerin işlemlerine ilişkin olarak kanunlar ihtilafı sorunlarının çözümü, sözleşmelerde irade serbestisinin mümkün olduğu durumlar ile bu tür sözleşmelerden kaynaklanan muhtemel uyuşmazlıkların çözümü için yetki sözleşmesine koyulabilecek uyuşmazlık çözüm yolları incelenmiştir. Ayrıca sözleşme konusu işlemlere Türk hukukunun uygulandığı durumlara ilişkin olarak, Türk hukuku çoğunlukla AB Hukuku ile karşılaştırılarak incelenmiştir. Şirket birleşme ve devralma işlemleri farklı yapıya sahip işlemlerdir. Bu sebeple her iki kavram iktisadi ve hukuki olarak tüm boyutları ile ele alınması ve farklılıklarının ortaya konulması gerekmektedir. Çünkü birleşme ve devralma işlemleri her ne kadar hukuki birer işlem niteliğinde olmalarına rağmen, sebeplerinin ve sonuçlarının iktisadi olduğunu söylemek mümkündür. Devralma kavramı, TTK.'da birleşmenin gerçekleşmesinin bir türü olarak kullanılmakla birlikte, gerçekte birleşme işleminden farklı olarak, bir şirketin kontrolünü sağlayacak şeklide ele geçirmek olarak anlaşılmalıdır. Birleşme işleminde, devrolunan şirket ya da şirketler devralan veya yeni kurulan şirketin bünyesine tasfiyesiz şekilde son bularak katıldığı halde, şirketin devralınması işleminde ise devralınan hedef şirket varlığını devam ettirmekte ve sadece kontrolünü sağlayan gerçek ya da tüzel şahıslar değişmektedir. Ayrıca birleşme işleminde devrolunan şirketin ortakları, ortaklığın devamlılığı ilkesi gereğince şirket payları karşılığında devralan şirketin ortağı olmakta ve genel kural olarak herhangi bir bedel ödemeleri söz konusu olmamakta, devralma işleminde ise devir karşılığında bir bedel ödenmesi söz konusu olmakta ve ortakların bu bedel karşılığında devrettikleri pay oranında, işlem konusu şirkete ilişkin mülkiyet hakları devir ile birlikte son bulmaktadır. Her iki uluslararası nitelikli sözleşmenin kurulma aşamasından önce, niyet mektubu, due diligence, gizlilik sözleşmesi gibi ortak yönleri bulunmaktadır. Ancak işlemlerin farklı hukuki yapıya ve özneye sahip olmaları sebebiyle, sözleşmenin kurulması, kanunlar ihtilafı kurallarına göre uygulanacak hukukun tespiti ile irade serbestisinin sözleşmeye uygulanabilmesi açısından birbirlerinden oldukça farklı nitelikleri bulunmaktadır. Her iki işlemden kaynaklı uyuşmazlıkların etkili ve pratik çözümü için yetki sözleşmelerine koyulabilecek başta tahkim olmak üzere, uyuşmazlık çözüm yolları da üzerinde özellikle durulması gereken konulardır
