Conference Object Citation - Scopus: 23Modified cognitive complexity measure(Springer Verlag, 2006) Misra,S.In cognitive functional size measure, the functional size is proportional to weighted cognitive complexity of all internal BCS's and number of input and output. This paper proposes the modification in cognitive functional size complexity measure. The proposed complexity measure is proportional to total occurrence of operators and operands and all internal BCS's. The operators and operands are equally important in design consideration. Thus, the contribution of the operators, operands and cognitive aspects complete the definition of a complexity measure in terms of cognitive. Accordingly, a new formula is developed for calculating the modified cognitive complexity measure. An attempt has also been made to evaluate modified cognitive complexity measure in terms of nine Weyuker's properties, through examples. It has been found that seven of nine Weyuker's properties have been satisfied by the modified cognitive complexity measure and hence establishes as a well-structured one. © Springer-Verlag Berlin Heidelberg 2006.Conference Object Citation - Scopus: 3Achieving Success in Supply Chain Management Software by Agility(Springer Verlag, 2007) Mishra,D.; Mishra,A.Supply chain management is comprehensive software. Due to its scope and unpredictable, complex and unstable requirements, it is not possible to develop it with predictable development process models. Agile methodologies are targeted towards such kind of problems that involves change and uncertainty, and are adaptive rather than predictive. The aim of this paper is to analyze the management and development methodologies used in development of supply chain management software. This paper shows how to overcome risks and handicaps in each development phase of a complex inventive project. It also provides a set of guidelines regarding how the agile methods may be adopted, combined and used in these kinds of projects. © Springer-Verlag Berlin Heidelberg 2007.Conference Object Adapting Test-Driven Development for Innovative Software Development Project(Springer Verlag, 2007) Mishra,D.; Mishra,A.In Test-Driven development, first test is made according to the customer requirement and then code is prepared to execute this test successfully. In this approach, design is not done exclusively before preparing test cases and coding. Design emerges as software evolves but this may result in lack of design quality. We adapted TDD by incorporating exclusive architectural design phase in the successful implementation of an innovative, large scale, complex project. © Springer-Verlag Berlin Heidelberg 2007.Conference Object Citation - Scopus: 2Evaluation of Partner Companies Based on Fuzzy Inference System for Establishing Virtual Enterprise Consortium(Springer Verlag, 2015) Nikghadam,S.; LotfiSadigh,B.; Ozbayoglu,A.M.; Unver,H.O.; Kilic,S.E.Virtual Enterprise (VE) is one of the growing trends in agile manufacturing concepts. Under this platform companies with different skills and core competences are cooperate with each other in order to accomplish a manufacturing goal. Success of VE, as a consortium, highly depends on the success of its partners. So it is very important to choose the most appropriate companies to enroll in VE. In this study a Fuzzy Inference System (FIS) based approach is developed to evaluate and select the potential enterprises. The evaluation is conducted based on four main criteria; unit price, delivery time, quality and past performance. These criteria are considered as inputs of FIS and specific membership functions are designed for each. By applying fuzzy rules the output of the model, partnership chance, is calculated. In the end, the trustworthy of the model is tested and verified by comparing it with fuzzy-TOPSIS technique providing a sample. © Springer International Publishing Switzerland 2015.Conference Object Citation - Scopus: 1Metu-Mmds: an Intelligent Multimedia Database System for Multimodal Content Extraction and Querying(Springer Verlag, 2016) Yazici,A.; Sattari,S.; Yilmaz,T.; Sert,M.; Koyuncu,M.; Gulen,E.Managing a large volume of multimedia data, which contain various modalities (visual, audio, and text), reveals the need for a specialized multimedia database system (MMDS) to efficiently model, process, store and retrieve video shots based on their semantic content. This demo introduces METU-MMDS, an intelligent MMDS which employs both machine learning and database techniques. The system extracts semantic content automatically by using visual, audio and textual data, stores the extracted content in an appropriate format and uses this content to efficiently retrieve video shots. The system architecture supports various multimedia query types including unimodal querying, multimodal querying, query-by-concept, query-by-example, and utilizes a multimedia index structure for efficiently querying multi-dimensional multimedia data. We demonstrate METU-MMDS for semantic data extraction from videos and complex multimedia querying by considering content and concept-based queries containing all modalities. © Springer International Publishing Switzerland 2016.Conference Object Citation - Scopus: 4Bicriteria Scheduling Problem on the Two-Machine Flowshop Using Simulated Annealing(Springer Verlag, 2010) Mesgarpour,M.; Kirkavak,N.; Ozaktas,H.Real life scheduling problems require the decision maker to consider a number of criteria before arriving at any decision. The trade-offs involved in considering several different criteria provide useful insights for the decision maker. Surprisingly, research in the field of multi-objective scheduling has been quite limited when compared to research in single criterion scheduling. The subject of this paper is the bicriteria scheduling problem in a two-machine flowshop. The objective is to find a job sequence that minimizes sum of weighted total flowtime and total tardiness. Based on the problem characteristics, a Simulated Annealing algorithm is developed. The proposed metaheuristic is compared with the branch and bound enumeration algorithm of the integer programming model as well as a modified version of the well-known NEH algorithm. During these evaluations, the experimental design approach and careful statistical analysis have been used to validate the effectiveness of the simulated annealing approach. © 2010 Springer-Verlag Berlin Heidelberg.Conference Object Citation - Scopus: 4Creating Awareness of Sleep-Wake Hours by Gamification(Springer Verlag, 2016) Ilhan,E.; Sener,B.; Hacihabiboğlu,H.Gamification can be used to motivate people to carry out hard-toperform tasks. It can help in changing undesirable habits and in improving a person’s subjective well-being. Sleep-wake behaviors are important determinants of day-to-day well-being. This study aims to find out whether it is possible to modify sleep-wake habits using gamification. To this end, a gamified alarm clock app, Sleepy Bird, was designed and tested in a user study with thirteen participants using gamified and thirteen participants using non-gamified versions for two weeks. The results indicate that the participants of the gamified version were more motivated to start the day at required times than the participants of the non-gamified version. The participants of the gamified version were also observed to have made desirable modifications to their sleep-wake habits. © Springer International Publishing Switzerland 2016.Conference Object Citation - Scopus: 4Analysis of B2c Mobile Application Characteristics and Quality Factors Based on Iso 25010 Quality Model(Springer Verlag, 2014) Yildiz,E.; Bilgen,S.; Tokdemir,G.; Cagiltay,N.E.; Erturan,Y.N.The number of mobile applications in mobile market has rapidly increased as new technology and new devices are emerging at remarkable speed which shows mobile applications have an important role in every field of our life. Among those, even some of the mobile applications have a long time life as end-users use those effectively, some of them fail to do so that prevents the companies to reach from their aim. The main reason of that problem results from the quality of the mobile applications. Although there are some methods and metrics to analyze the quality of mobile applications, they have lack of criteria since they are mostly based on ISO 9126 quality model factors which are invalid anymore. This study aims to analyze both mobile commerce applications' characteristics and quality factors and sub-factors based on ISO 25010 product quality model. Accordingly a quality model is proposed by analysis performed by a group of experts from the mobile software development area. The results of this study aims to help developing more qualified and effective mobile applications from developer perspective. © 2014 Springer International Publishing.Conference Object A Model for Measuring Cognitive Complexity of Software(Springer Verlag, 2008) Misra,S.; Akman,I.This paper proposes a model for calculating cognitive complexity of a code. This model considers all major factors responsible for (cognitive) complexity. The practical applicability of the measure is evaluated through experimentation, test cases and comparative study. © 2008 Springer-Verlag Berlin Heidelberg.Article Citation - Scopus: 5Text Categorization With Ila(Springer Verlag, 2003) Sever,H.; Gorur,A.; Tolun,M.R.The sudden expansion of the web and the use of the internet has caused some research fields to regain (or even increase) its old popularity. Of them, text categorization aims at developing a classification system for assigning a number of predefined topic codes to the documents based on the knowledge accumulated in the training process. We propose a framework based on an automatic inductive classifier, called ILA, for text categorization, though this attempt is not a novel approach to the information retrieval community. Our motivation are two folds. One is that there is still much to do for efficient and effective classifiers. The second is of ILA's (Inductive Learning Algorithm) well-known ability in capturing by canonical rules the distinctive features of text categories. Our results with respect to the Reuters 21578 corpus indicate (1) the reduction of features by information gain measurement down to 20 is essentially as good as the case where one would have more features; (2) recall/precision breakeven points of our algorithm without tuning over top 10 categories are comparable to other text categorization methods, namely similarity based matching, naive Bayes, Bayes nets, decision trees, linear support vector machines, steepest descent algorithm. © Springer-Verlag Berlin Heidelberg 2003.
