    In the modern world, electronic communications play a significant role in national and international electronic transactions. This issue has forced all legal systems to face up to many emerging legal problems in the context of electronic communications, such as the legal status of electronic agents in contracting electronically. Regarding the legal validity of e-contracts made through interactive websites, the legal status of electronic agents which play an important role in this process is questionable to see whether they are akin to real agents in the physical world or they are only a mere tool of communication. The current article tries to analyse this question by criticising a number of...

    , Article 4th International Conference on Information Technology-New Generations, ITNG 2007, Las Vegas, NV, 2 April 2007 through 4 April 2007 ; 2007 , Pages 885-887 ; 0769527760 (ISBN); 9780769527765 (ISBN) Shirali Shahreza, M ; Sharif University of Technology
    Upon development of m-commerce as one of the new branches of e-commerce, m-banking has emerged as one of the main divisions of m-commerce. As the m-banking was received very well, it has embarked upon supply of various services based on different systems and with the aid of various services such as the Short Messaging Service (SMS). However, in spite of its advantages, m-banking is facing some challenges as well. One of these challenges is the issue of security of this system. This paper presents a method for increasing security of the information requested by users with the use of steganography method. In this method, instead of direct sending of the information, it is hidden in a picture... 

    2PLoc: Preserving privacy in location-based services

    , Article Proceedings - SocialCom 2010: 2nd IEEE International Conference on Social Computing, PASSAT 2010: 2nd IEEE International Conference on Privacy, Security, Risk and Trust, 20 August 2010 through 22 August 2010 ; August , 2010 , Pages 707-712 ; 9780769542119 (ISBN) Amoli, A. S ; Kharrazi, M ; Jalili, R ; Sharif University of Technology
    Location-based services are becoming popular for mobile users. The mobile users' location plays a key role to provide the service from one side, but it can be considered as a dimension of their privacy and so necessary to keep it anonymous to the other parties. Since one important issue is to achieve an accurate service, it is important to use the mobile's accurate location. Using the location accurately raises some concerns on behalf of the user's privacy. One solution for meeting this requirement is using tickets by the means of a third party. The tickets should have some properties for not letting a mobile user to cheat and use the ticket more than one time. This paper proposes a protocol...

    Purchase prediction and item suggestion based on HTTP sessions in absence of user information

    , Article International ACM Recommender Systems Challenge, RecSys 2015, 16 September 2015 ; 2015 ; 9781450336659 (ISBN) Esmailian, P ; Jalili, M ; YOOCHOOSE ; Sharif University of Technology
    Association for Computing Machinery, Inc  2015
    In this paper, the task is to determine whether an HTTP session buys an item, or not, and if so, which items will be purchased. An HTTP session is a series of item clicks. A session has type buy, if it buys at least one item, or non-buy otherwise. Accordingly, data is in (session, item, time) format, which tells us when an item is clicked or purchased during an HTTP session. The main challenge comes from the fact that (1) user information is not available for clicked or purchased items, which are merely tagged with anony-mous sessions, and (2) suggestions are highly temporal as they are suggested to sessions instead of users. In other words, users which are stable and identified are replaced... 

    An incentive mechanism in smart networks using ascending reverse auction

    , Article IEEE International Symposium on Personal, Indoor and Mobile Radio Communications, PIMRC ; 2012 , Pages 42-47 ; 9781467325691 (ISBN) Golnarian, S ; Khalaj, B. H ; Sharif University of Technology
    In this paper, we use the ascending reverse auction method in incentive-based cooperative networks in order to increase the cooperation level of malicious users. Our approach integrates the reverse auction method with traditional pricing and reputation based algorithms and uses fuzzy thresholds to increase freedom of service providers in making the decision whether to cooperate or not. In contrast with earlier works, we do not concentrate on a specific network or protocol. The simulation results show that while the average welfare of malicious users is decreased dramatically, the average welfare of all users does not decrease significantly  

    The regulated market for kidneys in Iran

    , Article Lecture Notes of the Institute for Computer Sciences, Social-Informatics and Telecommunications Engineering, 22 August 2011 through 23 August 2011 ; Volume 80 LNICST , August , 2012 , Pages 62-75 ; 18678211 (ISSN) ; 9783642309120 (ISBN) Fatemi, F ; Sharif University of Technology
    We study the kidney market in Iran. The most effective treatment for end-stage renal disease is a kidney transplant. While the supply of cadaveric kidneys is limited, the debate has been focused on the effects of the existence of a free market for human organs. Economists as well as medical and legal researchers are divided over the issue. Iran has a unique kidney market which has been in place for over 20 years, frequently reporting surprising success in reducing the waiting list for kidneys. This paper demonstrates how the Iranian system works  

    Developing internet jurisdiction in B2B and B2C contracts: Focusing on Iranian legal system with comparative study of American, English and EU laws

    , Article Arab Law Quarterly ; Volume 31, Issue 3 , 2017 , Pages 276-304 ; 02680556 (ISSN) Habibzadeh, T ; Sharif University of Technology
    Brill Academic Publishers  2017
    In the modern world, electronic communications play a significant role in areas of national and international law such as Internet jurisdiction. Private international law provides that the competent court is the court within which jurisdiction the contract is performed, so it is important to know the place of performance of the contract in the case of contracts for digital goods such as e-books or computer software delivered online. It is equally important in the case of electronic services such as e-teaching. Furthermore, as consumer protection in B2C contracts is important in developing global e-commerce, it is important to consider whether the consumer party is able to bring an action...

Design/methodology/approach: This study used survey data from 234 Iranians with experience using social commerce sites. Variance-based... 

    Energy and contingency reserves markets under restructured electricity environment

    , Article 2006 IEEE GCC Conference, GCC 2006, Manama, 20 March 2006 through 22 March 2006 ; 2006 ; 9780780395909 (ISBN) Rashidinejad, M ; Gharaveisi, A. A ; Fotuhi Firoozabad, M ; Shojaee, M ; Sharif University of Technology
    Electricity industry is ongoing towards reregulation worldwide. Some new market issues that experienced in other commodities markets are suggested to be exercised in electricity markets. Electricity and ancillary services pricing under different schemes are such issues. Pricing mechanism can be applied via several sequential markets. A day-ahead market associated with joint energy and ancillary services dispatch is used as a benchmark for contingency reserves option pricing. This paper proposed a new methodology aimed to derive the option pricing for contingency reserves as a major part of ancillary services in restructured power systems

    Classified ads are one of the first E-Commerce formed after the introduction of the internet to the world which is still popular. Divar is one of the main online classified ads and thousands of transactions are happening daily. The transaction of demandant and supplier happens in a risky relation that needs trust to facilitate this transaction. In this research, we are trying to study trust models in the context of C2C E-commerce. As there are no structural assurance and feedback mechanisms in Divar, we decide to study the initial trust of members due to a lack of information from each other. In this research, we gather data from 385 participants by an online questionnaire. The results show...

    , M.Sc. Thesis Sharif University of Technology Sargazi Kousheh, Elham (Author) ; Amini Lari, Mansour (Supervisor) ; Beirjandi, Heshmat ($item.subfieldsMap.e)
    Construction is a large industry in Iran, it engages in a wide range of products. The raw materials which are used in making a building are fairly standard items: iron, cement, glass, and so on. Because the technologies for making a building are well-known, contractor can solicit bids from variety suppliers for raw materials without worrying about the possible disclosure of trade secrets. Unfortunately bidding processing in Iran becomes very slow and inefficient. Each transaction required to request the relevant telephone number to supplier that might be interested in bidding on the item, it would often take purchasing personnel more than one week to gather the information, send it to... 

    Optimal demand response aggregation in wholesale electricity markets

    , Article IEEE Transactions on Smart Grid ; Vol. 4, issue. 4 , 2013 , p. 1957-1965 ; ISSN: 19493053 Parvania, M ; Fotuhi-Firuzabad, M ; Shahidehpour, M ; Sharif University of Technology
    Advancements in smart grid technologies have made it possible to apply various options and strategies for the optimization of demand response (DR) in electricity markets. DR aggregation would accumulate potential DR schedules and constraints offered by small- and medium-sized customers for the participation in wholesale electricity markets. Despite various advantages offered by the hourly DR in electricity markets, practical market tools that can optimize the economic options available to DR aggregators and market participants are not readily attainable. In this context, this paper presents an optimization framework for the DR aggregation in wholesale electricity markets. The proposed study... 

    Assessment of public-private partnership in traveler information provision

    Making efficient use of transportation infrastructure has always been a concern. Traveler information provisions (TIPs) assist commuters in making better travel decisions and therefore lead to increased mobility and more efficient travel. The ongoing economic crisis and shrinking public funding have made the public-private partnership (PPP) an attractive instrument for promoting TIP. Such initiatives have been much discussed in developed countries. The use of PPP to fund public projects in developing countries, however, is in its infancy, and the related issues do not receive adequate attention in the literature. In this study, PPP opportunities in TIP were assessed in the case of a city in...
