With the expansion of the use of information technology and public access to financial markets, the number of players in this field has increased and as a result, the nonlinear behavior of the market has become more complex than before. Due to this issue, investors need specific strategies to identify suitable assets for investment and also to determine the time of entry and exit to the stock market in order to make a profitable investment. Therefore, the purpose of this study is to form a stock portfolio as an asset and based on an integrated approach of fundamental and technical analysis using machine learning techniques. In this research, the stock data of Tehran Stock Exchange and OTC... 

The role of Technological Human Body is mainly overlooked in the Philosophy of Technology. However as result of diverse bodily technologies (somatechnologies) which are emergent everyday, for either enhancement, rehabilitation, or even recreational activities, the realtion between bodies and technologies are such entangled that no longer could anybody ignor it. Cyborg is an amalgamation of Human and Machine. The philosophical challenges that such an entity brings forth is immense; Agency, Intentionality, Subjectivity, Power relations, Ethics to mention but a few. In this study we try to investigate such issues through a phenomenological and feminist stance by examining Everyday cyborgs, i.e.... 

Some philosophers and thinkers have made serious criticisms of modern technology, considering it the cause of major problems. These critiques and problems have motivated some philosophers to think of alternatives for technology. Andrew Feenberg, one of the scholars seeking alternatives for technology, argues that the modern technical system is derived from the values of capitalism and serves a select few. As a diagnosis, Feenberg considers the capitalistic values to be the root of modern technological crises and as a prescription, he recommends a “democratic technological design system”. Feenberg has proposed no criteria for evaluating the values that could be incorporated into the... 

In today’s highly competitive world, the countries with strong economies are able to produce their products at a lower price, better quality and at the right time in the market, therefore, in the performance evaluation of economic of the organizations and project management, several factors are involved; the most important are: time, price, and product quality. In this dissertation, a new method for performance evaluation in the field of project management based on combining the concept of the golden triangle of the project and the techniques available in decision science is presented. At first, three major areas of the golden triangle namely time, cost, and quality are selected for... 

The long-lasting debate on the value-free ideal of science has cooled down in the past two decades. Many philosophers of science now believe that scientific activity, even in the theory-evaluation phase, cannot be done completely free of social and ethical values. Thus in recent years, science and values literature has been more specific and mostly focused on the role of values in different phases of scientific activity. One of the well-noted topics is the epistemic priority thesis, in which its proponents prioritize epistemic considerations in the evaluation of scientific theories, to preserve the objectivity of science. In contrast, several criticisms have been directed at this thesis. We... 

Social constructionism and metaphilosophy are two fields that seem incompatible and different from each other. One is the point of view that at least part of the basic truths of human life-world, which gives meaning and foundation of his personality, are things made by humans themselves; At the same time, the other considers himself responsible for discovering the original and absolute truths and draws a line against the relativism and constructivism of the fundamental principles of human society. "Philosophical progress" which is the central content of this article, on the one hand, has taken root in the field of metaphilosophy to understand its philosophical nature, and on the other hand,... 

In this thesis, we will take a more profound study about what technology is and the relationship between technology development and society. We will discuss various theories such as the social construction of technology, the heterogeneous engineerings approach, the system approach, and the co-construction of society and technology. In this way, the relationship between economic and social systems and technological products is explained and based on this, an approach is proposed in relation to the ethical challenges in technology with a focus on social networks. The discussion is about the fact that due to the continuous use of technologies, a challenge may be raised in the technology... 

Sustainable energy supply and preservation of the environment have become the main motivations to integrate more renewable energy sources in electrical networks. However, with an increasing penetration of renewable energy sources in the modern electrical grids, new challenging issues arise regarding the power system planning, operation, control and protection. An important technical issue is the difficulty in achieving the frequency stability of these systems, as the renewables are often operated at the maximum power point, resulting in less generation units that provide reserve power. Moreover, the rotational inertia of the system is reduced due to the decoupling of the renewable energy...

What is meant by the scientific progress and how can it be explained? In response to this question, four distinct approaches—epistemic, semantic, problem-solving, and Noetic—have been presented. Each of these approaches defines the goal of science in a specific way: the epistemic approach considers the accumulation of scientific knowledge as the goal; the semantic approach views the goal as nearness to truth; the problem-solving approach sees the goal as solving more problems; and the Noetic approach sets the goal as increasing understanding. In this study, each approach is critically examined, and two central claims are made. The first claim asserts that to explain the scientific progress,... 

This thesis aim to the study of the effect of bank’s branching decisions on deposit market. Using panel data banks from Iran, we study effect of branching on market share and market size. In theoretical part, we assume that banks maximize discounted flow of the profits. We also assume that the banks take into account the reaction from rival banks in setting number of branches. Banks are assumed to expect the rival banks react by a lag of one period. In empirical part, in order to distinguish between aggregate market size effect and market share effect, we rewrite quantity of deposit in banks as the product of aggregate deposit and market share. We specify deposit market share function with... 

Selective Laser Melting (SLM) process is a powder-based metal Additive Manufacturing (AM) technique. This developing industry has many advantages like generation of geometrically complex shapes with high density. High Cost, production and characterization of powders, limited material choices and process parameters optimization are some of the challenges associated with SLM. Stainless steel 316L due to its unique properties, like corrosion resistance, high strength, biocompatibility, availability and cost is indeed a commonly used material in SLM. In this research, the characterization of the powder produced by the flame spraying device, which is a new method, was discussed. Wire with 3mm... 

One of the most important applications of artificial intelligence, and especially deep learning is image captioning. Given an image, the task is to automatically produce a sentence, describing the image. Image captioning has several real world applications like helping the blind understanding the images, generating automatic captions for the social media, etc. In the past, several different methods for image captioning have been used, but after the emergence of deep learning, like many other areas, image captioning algorithms have been improved significantly. In this thesis, I talk about a specific method for image captioning, called ”Deep Compositional Captioning. In this method, at first...
