Adobe structures are considered as masonry structures which are out of scope of 2800 Iranian code. Due to this code, since these structures are made of weak materials, they do not have a considerable resistance to earthquakes. Since these structures can be found all around Iran; therefore, seismic study of walls as an important component of these structures, is, indeed, necessary. During this study, cyclic tests on three types of adobe walls, without opening, with window-opening, and with door-and-window-opening with a scale of 2:3 were done to study their in-plane behavior and also their failure modes. Based on our observations, in these walls, because of small ratio of height to length,... 

The intermediary between Consumer and market of Natural gas is long transportation pipeline. Analysis of different dimension is a prerequisite for constructing these infrastructures. This study has been done in the fields of economics, environment and energy security. The proposed pipeline, which is called Islamic pipeline, passes through different countries, Iraq, Syria, Greece and Italy. It carries natural gas and feeds Europe gas requirements, also passes the Mediterranean Sea, which includes underwater pipe-laying technology that has been considered. Economic analysis of this project calculated, using Cost-Benefit analysis. Environmental issues has been identified and classified,... 

In recent decades, the growing number of eminent contemporary physicists, including Weinberg, Penrose, Isham, Susskind and etc. have doubted about the durability of quantum theory, and in the last year Weinberg, after analyzing the well-known interpretations of Standard quantum theory sees all of them as difficult and concludes that quantum theory needs to be replaced by a more comprehensive theory. The purpose of this dissertation is to analyze the critiques of Weinberg and others to the standard quantum theory and to study some of the alternative theories proposed, including the Bohemian quantum theory and the holographic universe  

In summary, this thesis presents a new mathematical model for Home Health Care (HHC) services during the Corona era, which aims to increase the efficiency and quality of services provided by these organizations while ensuring compliance with quarantine protocols. The model is an extension of the VRPPDTW formulation and considers relevant features such as patient classification, caregiver classification, work and break regulations, workload balancing, and multi-depot capabilities. The optimization can be performed with two separate objective functions, one to minimize traveling and idle costs and the other to minimize the total working time of caregivers. The contradictions between two... 

In Naming and Necessity and Identity and Necessity, Kripke convinced many that there are necessary propositions which are knowable only a posteriori. Kripke’s examples of these propositions can be placed into three categories: 1) Some mathematical propositions like Goldbach’s conjecture (the conjecture that every even integer greater than 2 can be expressed as the sum of two primes) 2) Scientific truths like “Water is H2O”, “Gold has the atomic number 79”, etc. 3) Identity statements flanked on both sides with proper names; like “Hesperus is Phosphorus”, “Cicero is Tully” and the like (in the rest of this article, these three categories will be called, respectively, the first, the second and... 

In his Mind, Brain and Free Will, Swinburne introduces a new argument for substance dualism based on the synchronic unity of humans’ conscious experiences. He argues that the human body cannot be the substance of such a synchronic unity, and that this coexperiencing property, which is a mental property, is the essential property of the human substance: hence our substance is a mental substance. After providing a careful explanation of Swinburne’s subtle argument, I first try to demonstrate that it is metaphysically possible that the brain itself could instantiate such a synchronic unity without the need to presume another substance. Then I shall argue that it is unclear how to infer the... 

This dissertation consists of three chapters. In the first chapter, a description of formation of Darwin's theory of Evolution is expressed. After that, the process of formation of modern theory of Evolution, along with an explanation of the theory of evolution and the evidence for it was mentioned. In the second season, which is responsible for the scientific study of the theory, at some point the evidence of this theory has been reviewed. After that, some of the challenges raised against this theory have been studied. The major scientific challenges described in this chapter is based on recent advances made in biology, based on that, the mechanism of theory can’t explain the complex... 

Wilfrid Stalker Sellars (1912-1989) is an analytic philosopher whose philosophy is famous for being deep, systematic and extremely influential and notorious for being difficult to read. Although he has many original and interconnected ideas in different branches of philosophy- including metaphysics, epistemology, philosophy of mind, ethics, philosophy of language and meta-philosophy- the place of science in his system is completely indispensable. In his meta-philosophy, Sellars defines his philosophical project as an attempt to reconcile two distinct world-views of humanity in the modern word; scientific image and manifest image. Approaching Sellars’ philosophy by placing science at the... 

Michael Zimmerman in his book Living with Uncertainty has objected to two views of moral obligation, namely objective and subjective view. Two overcome these problems he suggests a third view which he calls prospective view and tells us that our moral obligation is determined by the prospection that each of our choices give us. In this thesis first I review Zimmerman’s objections to objective and subjective view. Then I try to suggest a solution for the objective view  

Technological capabilities as one of the growth’s aspects in developing countries have gained focus for research in last years. This study attempt to analyze the pattern of technological capabilities in four different sectors including Optic, Aerospace, Pharmaceutical and Biotechnology. In each sectors four Iranian companies as the case studies are selected. After deep interviews with key people in each company, required data is gathered. Data in each company is analyzed. The results of analysis for companies in one sector are gathered for analyzing each sector. In order to evaluate technological capabilities, the time required to improve, lead-lag relationship for gaining higher levels of...
