Investigating the Necessity and Conditions of Implementing the Virtual Design and Construction Method (VDC); and Proposing a Process to Apply the Method in the Design and Construction Projects in Iran
, M.Sc. Thesis Sharif University of Technology ; Mortaheb, Mohammad Mehdi (Supervisor)
Abstract
By using the information and communication technology (ICT) in the past three decades, many industries have been able to improve their productivity to a great extent. However, the construction industry is not experiencing such growth in productivity. Many believe that one of the most important reasons for this problem is the ineffectual use of ICT in the construction industry. To solve this problem, several construction methods have been developed in order to increase the productivity of the construction industry by using the aspects of the ICT. One of the most promising methods in this area is the Virtual Design and Construction (VDC) method.

Towards interacting with smarter systems
, Article Journal of Ambient Intelligence and Humanized Computing ; Volume 9, Issue 1 , February , 2018 , Pages 187-209 ; 18685137 (ISSN) ; Nazari Shirehjini, A. A ; Daraei, S ; Sharif University of Technology

Abstract
The aim of this article is the requirement analysis, design, proof-of-concept implementation and user evaluation of a novel user interface that is specifically developed to support interaction with ambient intelligence systems. The focus of the user interface is rather on interacting with ambient intelligence, a meta system that comes into existence as the result of the coherent behavior and collective intelligence of interconnected smart devices and systems of a domain such as meeting rooms or smart homes. To design the user interface, we conducted an empirical user and task analysis and elaborated requirements, defining the scope of human interaction with ambient intelligence. The captured...

Introducing a Heuristic Approach to Solve Euclidean Traveling Salesman Problem and Evaluating the Accuracy
, M.Sc. Thesis Sharif University of Technology ; Mahlouji, Hashem (Supervisor) ; Qasemi Tari, Farhad (Co-Supervisor)
Abstract
The traveling salesman problem consists of a salesman and a set of cities in which the salesman has to visit each one of the cities only once, starting from an arbitrary city and returning to the same city. The challenge of the problem is that to find a trip to minimize the total length of the tour.The Travelling Salesman problem is a well-known and important combinatorial optimization problem. Despite this simple problem statement, solving the TSP is difficult since it belongs to the class of NP-complete problems. Due to its computational complexity, recent researches suggest that meta-heuristic approaches can be the best solution approach for the general form of this problem.This thesis...
Generative Software Development through Emergence-based Transformation
, M.Sc. Thesis Sharif University of Technology ; Ramsin, Raman (Supervisor)
Abstract
Due to the ever-increasing demand for larger and more complex software systems, generative software development has become an attractive alternative to traditional approaches. Generative software development is in fact a transition from one complexity space to another; the higher the ratio of the complexity of the destination space is to the complexity of the source space, the more ideal the level of generation will be. In the ideal case, generative software development becomes equivalent to fully-automated software development. Despite widespread research on generative software development approaches–such as Model-Driven approaches, Software Product-Lines, Generative Patterns, and...
Development of an Analytical Code for Simulation and Design of Spiral Wound Heat Exchanger in Cryogenic Applications
, Ph.D. Dissertation Sharif University of Technology ; Afshin, Hossein (Supervisor)
Abstract
This research aims to develop a numerical tool for design and performance evaluation of spiral wound heat exchanger (SWHE) in the cryogenic temperature range. This type of heat exchangers are used in gas liquefaction cycles due to their compact structure and ability to achieve high effectiveness values. High sensitivity of liquefaction cycles yield to heat exchanger effectiveness, effect of some physical phenomena in cryogenic temperature range, and complicated shell-side flow structure of SWHEs, turns the design and performance evaluation of cryogenic SWHEs into a challenging issue. Consequently, first of all, the geometrical parameters of SWHE were introduced and made dimensionless. In...
Formal verification of temporal questions in the context of query-answering text summarization
, Article Lecture Notes in Computer Science (including subseries Lecture Notes in Artificial Intelligence and Lecture Notes in Bioinformatics), 28 May 2012 through 30 May 2012 ; Volume 7310 LNAI , May , 2012 , Pages 350-355 ; 03029743 (ISSN) ; 9783642303524 (ISBN) ; Bakhshandeh Babarsad, O ; Ghassem Sani, G ; Sharif University of Technology

Abstract
This paper presents a novel method for answering complex temporal ordering questions in the context of an event and query-based text summarization. This task is accomplished by precisely mapping the problem of "query-based summarization of temporal ordering questions" in the field of Natural Language Processing to "verifying a finite state model against a temporal formula" in the realm of Model Checking. This mapping requires specific definitions, structures, and procedures. The output of this new approach is promisingly a readable and informative summary satisfying the user's needs

Abstract
The aim of this paper is the design and development of a novel user interface to interact with a meta system. Our focus is rather on interacting with Ambient Intelligence as a whole, which would for example enable users to influence the overall behavior and attributes of dynamic device compositions. We call such interfaces Meta User Interfaces. The design details of a proposed user interface as well as a cognitive walkthrough evaluation are presented in this paper

Abstract
Municipal solid waste (MSW) directly impacts community health and environmental degradation; therefore, the management of MSW is crucial. Medical waste is a specific type of MSW which is generally divided into two categories: infectious and non-infectious. Wastes generated by coronavirus disease 2019 (COVID-19) are classified among infectious medical wastes; moreover, these wastes are hazardous because they threaten the environment and living organisms if they are not appropriately managed. This paper develops a bi-objective mixed-integer linear programming model for medical waste management during the COVID-19 outbreak. The proposed model minimizes the total costs and risks, simultaneously,...
Study of Deactivation of Carbon Nanotubes Supported on Cobalt Catalysts in Fischer-Tropsch Synthesis
, M.Sc. Thesis Sharif University of Technology ; Kazemeini, Mohammad (Supervisor) ; Rohani, Ali Asghar (Supervisor)
Abstract
Purified RIPI–CNT was used as support material for the preparation of cobalt FTS catalysts. Carbon nanotubes supported catalysts (S1–S4) were prepared with loadings of 15, 20, 30 and 40 wt.%. The FT synthesis was carried out in a fixed-bed micro reactor. Deactivation factors of cobalt catalysts supported on carbon nanotubes in FT synthesis is investigated. Using carbon nanotubes as cobalt catalyst support was found to cause the reduction temperature of cobalt oxide species to shift to lower temperatures. The strong metal-support interactions are reduced to a large extent and the reducibility of the catalysts improved significantly. Then, the main reason for the catalyst deactivation will be...

Abstract
Today, research on automatic text summarization challenges on readability factor as one of the most important aspects of summarizers' performance. In this paper, we present Pazesh: a language-independent graph-based approach for increasing the readability of summaries while preserving the most important content. Pazesh accomplishes this task by constructing a special path of salient sentences which passes through topic centroid sentences. The results show that Pazesh compares approvingly with previously published results on benchmark datasets
