Conference Object Citation - WoS: 2Citation - Scopus: 14Exploring Collaboration Patterns Among Global Software Development Teams(Ieee Computer Soc, 2009) Serce, Fatma Cemile; Alpaslan, Ferda-Nur; Swigger, Kathleen; Brazile, Robert; Dafoulas, George; Lopez, Victor; Schumacker, RandyThis study examines communication behaviors in global software student teams. The authors of the paper characterize the types of communication behaviors that occur when student teams are engaged in a software development project. The authors present findings from a one-semester study that examined factors contributing to successful distributed programming interactions among students enrolled at the University of Atilim (Turkey), Universidad Tecnologica de Panama, University of North Texas, and Middlesex University (UK). Using content and cluster analyses techniques, we identified distinct patterns of collaboration and examined how these patterns were associated with task, culture, GPA, and performance of collaborative teams. Our results suggest that communication patterns among global software learners may be related to task type, culture and GPA. It is hoped that these findings will lead to the development of new strategies for improving communication among global software teams.Article Citation - WoS: 16What We Know About Software Test Maturity and Test Process Improvement(Ieee Computer Soc, 2018) Garousi, Vahid; Felderer, Michael; Hacaloglu, Tuna[No Abstract Available]Conference Object Citation - WoS: 4A Comparison of Team Performance Measures for Global Software Development Student Teams(Ieee Computer Soc, 2009) Swigger, Kathleen; Serce, Fatma Cemile; Alpaslan, Ferda Nur; Brazile, Robert; Dafoulas, George; Lopez, VictorOne of the most difficult tasks for global software development researchers is quantifying the performance of groups and students who participate in these distributed projects [30]. There has been much debate about which factors better correlate with team performance and which best describe a successful team. The purpose of this paper is to compare the different approaches that have been used to evaluate the performance of global software learners and show how these techniques can affect research results. Using data from student groups engaged in global software development projects for the past year, the authors apply a number of different assessment methods and show their effects on different performance indicators. Our study suggests that the selection of appropriate measures to evaluate team performance can dramatically affect how one identifies successful teams.Conference Object An Alternative Product Extraction Method for E-Commerce Applications(Ieee Computer Soc, 2007) Koyuncu, MuratCustomers generally like to see alternative products and compare their characteristics and prices before deciding on one of them. Therefore, proposing alternative products is one of the crucial issues for e-commerce applications to increase customer satisfaction. This paper proposes a fuzzy similarity-based approach to determine similar products recorded in a database and submit them intelligently to the customer in a ranked way as alternative products.Conference Object Citation - WoS: 2Citation - Scopus: 2Process Matchmaking on a P2p Environment(Ieee Computer Soc, 2006) Celebi, Remzi; Çelebi, Remzi; Ellezer, Huseyin; Baylam, Cemi; Cereci, İbrahim; Cereci, Ibrahim; Kilic, Hurevreni; Çelebi, Remzi; Cereci, İbrahim; Computer Engineering; Computer EngineeringA process matchmaking environment based on P2P architecture and Gnutella protocol is established Java Agent Development Framework (JADE) is used as middleware. The processes are modeled as one-input transition systems augmented by goal state descriptions. A polynomial-time algorithm for handling matchmaking of peer process encounters is developed The environment can easily be customized to a specific application domain by simple user-interface modifications and through the development of related state ontologies.Conference Object Citation - WoS: 1Gezgin & Gezgin-2(Ieee Computer Soc, 2006) Ismailoglu, N.; Benderli, O.; Yesil, S.; Sever, R.; Okcan, B.; Sengul, O.; Oktem, RusenGEZGIN and GEZGIN-2 are real-time multispectral image processing subsystems developedfor BILSAT-1 and RASAT satellites respectively, the first two earth observing small satellites of Turkey. Main functionality of these subsystems is to compress in real-time multi-spectral images received concurrently from imagers, using JPEG2000 Image Compression algorithm. The compression features are controlled through user-supplied parameters uploaded in-orbit, so that the compression rate could be adapted to bandwidth, image quality and other mission requirements. GEZGIN employs both reconfigurable hardware and a DSP processor for image processing, where as the more advanced GEZGIN-2 contains full integration of the JPEG2000 processing path plus other image pre-processing features on reconfigurable hardware, hence offering increased performance and full re-configurability in orbit. Both systems demonstrate space-tailored architectures for implementing image processing functions where adaptability becomes the crucial issue determining robustness, flexibility and survivability of the system.Conference Object Revisiting Shamir's No-key Protocol: Lightweight Key Transport(Ieee Computer Soc, 2017) Kilic, Adnan; Onur, Ertan; Onur, Cansu BetinKey-transport protocols, subclasses of key-establishment protocols, are employed to convey secret keys from a principal to another for establishing a security association. In this paper, we propose a lightweight, practicable, tweakable, energy-efficient, and secure key-transport protocol, suitable for wireless sensor networks (WSN), Internet of Things (IoT) and mobile networks. The proposed protocol is based on the Shamir's no-key protocol. Although Shamir's no-key protocol does not require any pre-shared secret between principals, we show that it is impossible to employ the no-key protocol over public commutative groups. We modify Diffie-Hellman key-agreement protocol to morph it into a key-transport protocol by applying a set of changes on the original protocol and it becomes possible to compare both protocols in terms of memory usage and total time to accomplish a single key transport. The experimental results show that the proposed key transport protocol perform faster than the modified Diffie-Hellman protocol, and the total time to transport a single key by using the modified Diffie-Hellman protocol grows drastically with the increase in key size.
