Modeling Cash Flows Under IFRS17: TÜRK Case Jubeh, Rinad; Kestel, Sevtap Ayşe; Haçarız, Oytun; Department of Actuarial Sciences (2022-8-5) By the introduction of IFRS17, vital changes in measurements of insurance contracts are expected. This requires to assess the liabilities of insurance companies by two kinds. These are (i) fulfilment cash flows and (ii) contractual service margin, in which policyholder cash flows are the nucleus of both. Hence, this thesis consists of two main parts. Firstly, we use panel data analysis to analyze policyholder cash flows in respect to Türk returns, insurer’s cash outflows and changes in cash. Secondly, we co...

Mixtures were evaluated to identify behavioral thresholds and address backfill restrictions in commonly used guidelines to design reinforced earth walls. All CFM specimens were initially compacted to 95% of standard Proctor dry density at optimum moisture content. Index, hydraulic properties,...
THE IMPACT OF PHYSICAL ENVIRONMENTAL DESIGN ON USERS’ SENSE OF SAFETY IN OPEN SPACES: INCREASING PALESTINIAN REFUGEES’ SENSE OF SAFETY IN OPEN SPACES IN BAQA’A CAMP IN JORDAN ABUZAID, HADEEL; Severcan, Yücel Can; Akkar Ercan, Zübeyde Müge; Department of City and Regional Planning (2022-6-16) Since the Israeli-Palestinian conflict in 1948, thousands of Palestinians have been forced to leave their home and be displaced to poor urban settlements. The High Commissioner for Refugees (UNHCR) recognized that safety issues in camp areas might affect refugees' experience in open spaces. Baqa'a refugee camp in Jordan is one of the largest Palestinian refugee camps in the middle east, with a high proportion of refugees, so it provides research context for open spaces in permanent refugee camps. This study...

FINITE GROUP ACTIONS ON FOUR MANIFOLDS Küçük, Başak; Pamuk, Semra; Department of Mathematics (2022-7-21) In the area of group actions on manifolds, we either fix a group G and ask the question whether G acts or not on some certain manifolds or we fix the manifold M and ask which groups can act on M in a certain way. In this thesis, we will focus on the latter; present some known and recent results about finite group actions on closed, connected, orientable four-manifolds. The group actions that are considered are topological and locally linear. We will give a detailed overview of the rank conditions of the gro...
THE IMPACT OF REFUGEE STATUS ON LANGUAGE AND COGNITIVE DEVELOPMENT: A COMPARATIVE STUDY Yeter, Özlem; Özge, Duygu; Temürcü, Ceyhan; Department of Cognitive Sciences (2022-7-29) To this day, there is no detailed information on how experiences related to forced displacement affect cognitive and linguistic development of the Syrian refugee children. To address this gap in the literature, 25 low-SES Syrian refugee children (9-year-old) were tested for their working memory (WM), inhibitory control (IC), shifting, fluid intelligence abilities as well as vocabulary abilities. Their scores were compared with two low-SES non-refugee same-age control groups: Turkish monolinguals (N = 20) an...
Numerical Modeling of Long Waves from Atypical Sources: Atmospheric Disturbances and Volcanic Origin Doğan Bingöl, Gözde Güney; Yalçıner, Ahmet Cevdet; Department of Civil Engineering (2022-6-30) Earthquakes are the main cause mechanisms of tsunamis and large tsunamigenic earthquakes, especially in the subduction zones, occur on relatively much shorter timescales, but destructive tsunamis are also produced by volcanic eruptions, which have been threatening the coastal communities throughout history. Furthermore, while earthquake-generated tsunamis have been studied immensely, there is less focus on research related to tsunamis induced by atmospheric disturbances (meteotsunamis). Consequently, this s...
SGLC: A LOGICAL CLOCK USING SUCCINCT GRAPHS Sokoto, Saidu Aliyu Isa; Onur, Ertan; Department of Computer Engineering (2022-7-1) This thesis presents a new logical clock, SGLC, capable of capturing causality relationships in distributed systems. SGLC relies on a succinct graph representation codable and decodable in polynomial time while storing the graphs as integers. What makes SGLC feasible is that directed graphs can be used to implement logical clocks. Consequently, the main goal of introducing SGLC is to reduce the communication overhead of transporting causal history graphs by encapsulating the causality relationships of event...

A Parameter Error Identification Method for Power Plant Dynamic Models Açılan, Etki; Göl, Murat; Department of Electrical and Electronics Engineering (2022-6-30) Incorrect parameters in a power plant dynamic model affect the analysis results and control decisions in a power system, which may have serious consequences. The online calibration techniques in the literature utilize sensitivity analysis to determine the identifiable parameters before the calibration, and treat majority of sensitive parameters as potentially erroneous. Hence, the candidate parameter subset for calibration mostly consists of distractors, i.e. highly sensitive but already correct parameters....
EFFECTIVENESS OF CONCEPTUAL CHANGE STRATEGIES IN SCIENCE EDUCATION: A META-ANALYSIS Paçacı, Çağatay; Özdemir, Ömer Faruk; Üstün, Ulaş; Department of Secondary Science and Mathematics Education (2022-6-29) There is extensive literature focusing on students’ misconceptions in various subject domains. Several conceptual change approaches have been trying to understand how conceptual change occurs to help learners handle these misconceptions. This meta-analysis aimed to integrate studies investigating the effectiveness of three types of conceptual change strategies; cognitive conflict, cognitive bridging, and ontological category shift in science learning. We conducted a random-effects meta-analysis to calculate...
Kernel probabilistic distance clustering algorithms Özkan, Dilay; İyigün, Cem; Department of Industrial Engineering (2022-7) Clustering is an unsupervised learning method that groups data considering the similarities between objects (data points). Probabilistic Distance Clustering (PDC) is a soft clustering approach based on some principles. Instead of directly assigning an object to a cluster, it assigns them to clusters with a membership probability. PDC is a simple yet effective clustering algorithm that performs well on spherical-shaped and linearly separable data sets. Traditional clustering algorithms fail when the data ...
EVALUATION OF SUSTAINABILITY IN HOSPITALITY SECTOR IN TURKEY AND COMPARATIVE LIFECYCLE ASSESSMENTS OF ACCOMMODATION OPTIONS Akdemir Yılmaz, Kadriye; Elias Özkan, Soofia Tahira; Department of Building Science in Architecture (2022-5-11) Currently, one of the most important factors influencing the future of the world is tourism, due to its negative effects on the natural environment and consumption of natural resources. The tourism sector, which offers its guests natural and cultural beauties in the region where it is located, will not be able to survive if the potential danger to natural environment and resources is not halted. In other words, sustainable tourism is entirely dependent on the sustainability of the environment and resources....
