this dissertation has six chapter and tree appendices. chapter 1 introduces the thesis proposal including description of problem, key questions, hypothesis, backgrounds and review of literature, research objectives, methodology and theoretical concepts (key terms) taken the literature and facilitate an understanding of national security, national interest and turkish- israeli relations concepts...
Analyzing the author and topic relations in email corpus is an important issue in both social network analysis and text mining. The AuthorTopic model is a statistical model that identifies the author-topic relations. However, in its inference process, it ignores the information at the document level, i.e., the co-occurrence of words within documents are not taken into account in deriving topics...
Underwater explosion is a common phenomenon to be considered for marine and coastal structures .Although it is not wise to design such structures based on explosion loads, but having studied the explosion wave and its demotic effects, location and geometries of these structures can be improved. In this study after introducing underwater explosion mechanism a summary of the numerical methods use...
grade control structures are hydraulic structures used to stabilize a river bed. scour downstream of this structure is the main cause of its failure. studies have developed numerous empirical relations for scour depth prediction that designers must choose between to decide the most effective equation for a specific application. this study tested the condition of submerged jets over beds of sedi...
Object relations have A key role in psychoanalytic approach. Thus providing a persian version of a scale to assess object relations is helpful for elaborating empirical studies in this approach. the aim of the present study is to investigate validity, reliability, and factorial structure of the Persian version of ...
In this paper we derive semi-empirical Cepheid period-luminosity (P-L) relations in the Sloan ugriz magnitudes by combining the observed BV I mean magnitudes from the Large Magellanic Cloud Cepheids (LMC) and theoretical bolometric corrections. We also constructed empirical gr band P-L relations, using the publicly available Johnson-Sloan photometric transformations, to be compared with our sem...
This paper develops a new exploratory method for analyzing the relations among distributions of spatial objects. Existing methods usually focus on the distribution of one or two types of spatial objects. This paper, on the other hand, deals with the relations among more than two distributions of spatial objects. In addition, the method is applicable independent of the type of spatial objects. T...
The present paper deals with the problem of evaluating empirical evidence for therapeutic decisions in medicine. The article discusses the views of Nancy Cartwright and John Worrall on the function that randomization plays in ascertaining causal relations with reference to the therapies applied. The main purpose of the paper is to present a general idea of alternative method of evaluating empir...
Aims The possible influence of solar superflares on the near-Earth space radiation environment are assessed through investigation scaling laws between peak proton flux and fluence Solar Energetic Particle (SEP) events with flare soft X-ray photon flux. Methods We compiled a catalog 65 well-connected (W20-90) SEP during last three cycles covering period $\sim$34 years (1984-2020) that were assoc...
