    Comparison between stability, electronic, and structural properties of cagelike and spherical nanodiamond clusters

    , Article Physical Review B - Condensed Matter and Materials Physics ; Volume 76, Issue 3 , 2007 ; 10980121 (ISSN) Heidari Saani, M ; Kargarian, M ; Ranjbar, A ; Sharif University of Technology
    2007
    Abstract
    Ab initio density functional theory calculations were used to investigate cohesive, electronic, and structural properties of cagelike and spherical hydrogen terminated nanoparticles of diamond. Unlike cagelike nanodiamond particles, the variation of calculated energies of spherical ones is not monotonic. The variation range of the calculated energies and bond lengths of cagelike nanoparticles is much tighter than the variation range of spherical ones. In contrast to spherical nanodiamond particles, the C-C bond lengths of all cagelike nanoclusters are very similar to the bond length of bulk diamond. The comparison of stability, electronic highest occupied molecular orbital-lowest unoccupied...

    Abstract
    Continuity and reliability of electricity supply in a country are vital to the operational continuity of the critical infrastructure and government. High levels of cyber security are required to achieve such key measures in the electricity industry. We propose solutions and models on how to improve the cyber security using the maturity model in order to achieve continuity of electricity supplies. Maturity levels start from the relative level (level 1) and continue to the adaptive level (level 4). A total of 10 domains are defined in the model. The practices of cyber security are clustered into domains. The model is used for assessment of the strength and weakness factors for the...

    Abstract
    Ensuring that organizational IT is in alignment with and provides support for an organization's business strategy is critical to business success. As there is no published research that attempts to describe maturity of ITIL V3 in aligning business and IT at strategic level, this paper reports on determining aligning roles of ITIL V3 in practice. In this paper, ITIL maturity to business-IT strategic alignment is validated by Strategic Alignment Maturity model. Focusing on how ITIL V3 covers business-IT alignment maturity criteria of the model, the maturity of ITIL strategic alignment practices is assessed which makes it possible to recognize conceptual and practical competencies of ITIL to... 

    Malicious Network Flow Detection based on Behavioral Characteristics of Users

    , M.Sc. Thesis Sharif University of Technology Zargar, Abolfazl (Author) ; Jalili, Rasoul (Supervisor)
    Abstract
    Insider threat is a significant security risk for organizations and hard to detect. Most of introduced detection methods need contextual data entries about users, or preprocessed user activity logs to detect insider threats while it is costly and time-consuming. In this thesis, we introduce a behavior analysis method that learns its context and detects multiple types of insider threats from raw logs and network traffic in real-time. This method, named XABA, learns user roles and exclusive behaviors, through analyzing raw logs related to each network session of the user. Then it checks for some abnormal patterns, and if so, triggers the appropriate alert. XABA is implemented on the big-stream...

    Abstract
    Particle Swarm Optimization (PSO) is a well-known swarm intelligence (SI) algorithm employed for solving various optimization problems. This algorithm suffers from premature convergence to local optima. Accordingly, a number of PSO variants have been proposed in the literature. These algorithms exploited different schemes to improve performance. In this paper, we propose a new variant of PSO with an enhanced Learning strategy and Crossover operator (PSOLC). This algorithm applies three strategies, comprising altering the exemplar particles, updating the PSO parameters, and integrating PSO with Genetic Algorithm (GA). In the proposed learning strategy, each particle is guided by the best... 

    Information resource management maturity model

    , Article World Academy of Science, Engineering and Technology ; Volume 37 , 2009 , Pages 258-262 ; 2010376X (ISSN) Afshari, H ; Khosravi, Sh ; Sharif University of Technology

    Abstract
    Nowadays there are more than thirty maturity models in different knowledge areas. Maturity model is an area of interest that contributes organizations to find out where they are in a specific knowledge area and how to improve it. As Information Resource Management (IRM) is the concept that information is a major corporate resource and must be managed using the same basic principles used to manage other assets, assessment of the current IRM status and reveal the improvement points can play a critical role in developing an appropriate information structure in organizations. In this paper we proposed a framework for information resource management maturity model (IRM3) that includes ten best... 

    A PSO based approach for multi-stage transmission expansion planning in electricity markets

    , Article International Journal of Electrical Power and Energy Systems ; Vol. 54, issue , 2014 , pp. 91-100 ; SSN: 01420615 Kamyab, G. R ; Fotuhi-Firuzabad, M ; Rashidinejad, M ; Sharif University of Technology
    Abstract
    This paper presents a particle swarm optimization (PSO) based approach to solve the multi-stage transmission expansion planning problem in a competitive pool-based electricity market. It is a large-scale non-linear combinatorial problem. We have considered some aspects in our modeling including a multi-year time horizon, a number of scenarios based on the future demands of system, investment and operating costs, the N - 1 reliability criterion, and the continuous non-linear functions of market-driven generator offers and demand bids. Also the optimal expansion plan to maximize the cumulative social welfare among the multi-year horizon is searched. Our proposed PSO based approach, namely... 

    Heterogeneity in preferences of air travel itinerary in a low-frequency market

    , Article Transportation Research Record ; Issue 2214 , 2011 , Pages 10-19 ; 03611981 (ISSN) Rezaei, A ; Puckett, S. M ; Nassiri, H ; Sharif University of Technology
    2011
    Abstract
    Research in the choice behavior of air travelers has evolved to include an analytical focus on variation in the sensitivities of travelers to factors influencing itinerary choice. Some choice studies have moved beyond a focus on assumed representative, mean-level sensitivities toward a goal of representing the distribution of preferences across a sample. The mixed multinomial logit model has served as a valuable means of estimating such distributions of air travel preferences, including studies of business travelers, impacts of airport level-of-service attributes, distributions of willingness-to-pay (WTP), and information-processing strategies. Does the insight gained in previous studies,...

    Abstract
    With regard to increased sustainability, managers not only need to know WHAT is needed for their company to improve, but also HOW to do so in detail is equally important. Energy management (EnM) is a pillar to the transformation of industrial energy systems towards enhanced energy efficiency and increased sustainability. One way to develop more and improve EnM both practically and theoretically is to shed light on how the combination of techniques and operation can contribute to successful EnM. This paper, therefore, through investigation of 10 Swedish foundries aims to present the structure of the energy strategy and associated practices at first; second, to assess industry’s EnM program...

    , M.Sc. Thesis Sharif University of Technology Bagher Esmaili Feijani, Haleh (Author) ; Shadrokh, Shahram (Supervisor)
    Abstract
    The literature suggests that organizations cannot be competitive if their business and information technology strategies are not aligned. Yet achieving strategic alignment continues to be a major concern for business executives. A number of alignment models have been offered in the literature, primary among them the Strategic Alignment model (SAM), Strategic Alignment Maturity model, and IT Governance (via ITIL). The Information Technology Infrastructure Library (ITIL) presents a comprehensive set of guidelines for defining, designing, implementing and maintaining IT Service Management processes. It provides platform that can be used to leverage complementary effects between IT and business...
