Conference Object Citation - Scopus: 3Error Density Metrics for Business Process Model(2009) Tonbul,G.; Misra,S.In this paper, metrics for business process model (BPM), are proposed, which are capable to measure the usability and effectiveness of BPMs. The proposed model is adapting error density metrics to BPMs by considering the similarities between the conceptual characteristics of BPMs and software products. We applied seven software metrics for evaluating quality of business processes/process models. Results show that our metrics help the organization to improve their process, as weighted measurements are indicators for unexpected situations/behaviour for business processes. © 2009 IEEE.Conference Object A Linear Time Algorithm for the Prediction of Compression During Multimedia Transmission(2009) Çevik,A.In this paper, alternative approaches and solutions are introduced to improve the quality of multimedia transmissions on various services. Regarding the improvement, several approaches are proposed incluing an automated network feedback approach based on a two-way language protocol. Secondly, and independent from automated feedback, measure-once and linear-time measure-many tracking algorithms are proposed in order to make an approximation about the quality/compression ratio of the transmission of a multimedia object.Conference Object Citation - Scopus: 9Modeling Flexforming (fluid Cell Forming) Process With Finite Element Method(Trans Tech Publications Ltd, 2007) Ali Hatipoǧlu,H.; Polat,N.; Köksal,A.; Erman Tekkaya,A.In this paper, the flexforming process is modeled by finite element method in order to investigate the operation window of the problem. Various models are established using explicit approach for the forming operation and implicit approach for the unloading one. In all analyses the rubber diaphragm has been modeled revealing that the modeling of this diaphragm is essential. Using the material Aluminum 2024 T3 alclad sheet alloy, three basic experiments are conducted: Bending of a straight flange specimen, bending of a contoured flange specimen and bulging of a circular specimen. By these experiments the effects of blank thickness, die bend radius, flange length and orientation of the rolling direction of the part have been investigated. Experimental results are compared with finite element results to verify the computational models.Conference Object Comparative Study of Cognitive Complexity Measures(Ieee, 2008) Misra, Sanjay; Mısra, Sanjay; Akman, Ibrahim; Akman, Kamil İbrahim; Mısra, Sanjay; Akman, Kamil İbrahim; Computer Engineering; Computer EngineeringComplexity metrics are used to predict critical information about reliability and maintainability of software systems. Cognitive complexity measure based on cognitive informatics, plays an important role in understanding the fundamental characteristics of software, therefore directly affects the understandability and maintainability of software systems. In this paper, we compared available cognitive complexity measures and evaluated cognitive weight complexity measure in terms of Weyuker's properties.Conference Object Citation - Scopus: 2Effect of Discontinuity Orientation and Spacing on the Blasting Performance in Some Open Cast Mines of Tki-Turkey(International Society for Rock Mechanics, 2003) Kaçar,G.; Özgenoglu,A.; Bilgin,H.A.In this study, the influences of rock mass properties on the blasting performance in open cast mines are investigated. To this end, discontinuity spacings and discontinuity orientations are measured and full scale blasts with various designs are observed in open cast mines of Aegean Lignite (ELI) and Bursa Lignite (BLI) Establishments belonging to Turkish Coal Enterprises (TKI). For each blast, blasting cost is calculated, and particle size distribution representing the fragmentation of muckpile is determined by means of Split-Desktop software using image processing. 50%(K50), 80%(K80) passing sizes and topsize values are used in the determination of blasting performance according to rock mass properties. The relationships between orientation angle, which is the acute angle between the strikes of slope face and major discontinuity, and 50%(K50) and 80%(K80) passing sizes and topsize values and also blasting cost are investigated in order to analyse the influences of major discontinuity orientation on fragmentation and blasting cost. Furthermore, the relationships between discontinuity modal spacing (or block size index) and 50%(K50) and 80%(K80) passing sizes and topsize values and also blasting cost are investigated in order to analyse the influences of discontinuity spacing on fragmentation and blasting cost. In this paper, the trends observed in these relationships are discussed and the importance of it in mining is commented. © 2003 10th ISRM Congress.

In this paper, a discrete calculus of variations for sums is treated, including the discrete Euler-Lagrange equation.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.Conference Object Citation - Scopus: 1Artificial agent society simulations in an encounter-based normative action environment(2007) Kiliç,H.The purpose of the study is to investigate potential relationship between agents' socialness and society's behavior predictability in an encounter-based normative action environment. For this purpose, we proposed a hypothesis and tested it against different simulation setups in the context of classical single source shortest path problem. By the end of simulations, it is observed that the hypothesis holds for both norm internalization and spreading measures when the agents in society have some degree of autonomy. That means for our setup, we conclude that lower degree of socialness results in lower behavioral predictability of the society when the agents have some degree of autonomy. ©2007 IEEE.Conference Object Citation - Scopus: 57Successful Requirement Elicitation by Combining Requirement Engineering Techniques(2008) Mishra,D.; Mishra,A.; Yazici,A.The role of customers and other stakeholders is becoming increasingly significant during requirement engineering activities. Methods of eliciting requirements are now more co-operative. There are many techniques to obtain requirements from customers. Selecting the right techniques according to the characteristics of the project is very important. In some complex problems, combination of requirement engineering techniques should be applied for efficient and successful requirement engineering process. In this paper, we have presented the application of combination of requirement engineering techniques for a real life complex project (Supply Chain Management) with higher requirements volatility developed in a small scale software development organization.This will help in understanding requirements elicitation for such kind of complex software and facilitate in selecting the appropriate techniques towards getting the consistent and complete requirements. ©2008 IEEE.Conference Object How Assessment System of an Open Source Learning Management System Can Be Integrated To a Remote Laboratory Application? Problems and Solutions(Ieee, 2007) Aydin, Cansu Cigdem; Cagiltay, Nergiz ErcilMost of the education programs need an assessment system for formative and summative evaluation purposes. Similarly, in the ERRL* project which is a distance remote radio frequency laboratory application, assessment system is required. However, developing an assessment system cost is very high and requires some extra time for testing and development purposes. Open source systems provide these services in a standard way. Since the source is open, it is possible to make some modifications to better adapt these systems to the requirements of developed systems. Similarly, in the Moodle part of the system we need to integrate the test and the experiment platforms. hi order to better guide the learners in the system, they should take some tests about the devices and the theoretical content included in the system. It is important to prevent users Who do not have the enough knowledge directed to the experiments platform. These testing requirements should be integrated into the remote laboratory system, so that, the learners should not need to jump between different systems and interfaces. This article presents implementation process of open source Learning Management System software's assessment module to a remote laboratory application and it also discusses the advantages, disadvantages of using an open source Web based assessment system.
