    A Cognitive Evaluation for Meetings in Software Development Process
    (Springer-verlag Berlin, 2009) Misra, Sanjay; Akman, Ibrahim
    Software development; includes number of different type of meetings in the whole development process. The cognitive activities also play an important role in decision making activities in these meetings since they are carried out, by human being. In this paper, we evaluated the relevance of meetings in different phases of the software development process with reference to cognitive aspects.

    Jmathnorm: a Database Normalization Tool Using Mathematica
    (Springer-verlag Berlin, 2007) Yazici, Ali; Karakaya, Ziya
    This paper is about designing a complete interactive tool, named JMathNorm, for relational database (RDB) normalization using Mathematica. It is an extension of the prototype developed by the same authors [1] with the inclusion of Second Normal Form (2NF), and Boyce-Codd Normal Form (BCNF) in addition to the existing Third normal Form (3NF) module. The tool developed in this study is complete and can be used for real-time database design as well as an aid in teaching fundamental concepts of DB normalization to students with limited mathematical background. JMathNorm also supports interactive use of modules for experimenting the fundamental set operations such as closure, and full closure together with modules to obtain the minimal cover of the functional dependency set and testing an attribute for a candidate key. JMathNorm's GUI interface is written in Java and utilizes Mathematica's Mink facility to drive the Mathematica kernel.

    A New Classifier Design With Fuzzy Functions
    (Springer-verlag Berlin, 2007) Celikytlmaz, Ash; Tuerksen, I. Burhan; Aktas, Ramazan; Doganay, M. Mete; Ceylan, N. Basak
    This paper presents a new fuzzy classifier design, which constructs one classifier for each fuzzy partition of a given system. The new approach, namely Fuzzy Classifier Functions (FCF), is an adaptation of our generic design on Fuzzy Functions to classification problems. This approach couples any fuzzy clustering algorithm with any classification method, in a unique way. The presented model derives fuzzy functions (rules) from data to classify patterns into number of classes. Fuzzy c-means clustering is used to capture hidden fuzzy patterns and a linear or a non-linear classifier function is used to build one classifier model for each pattern identified. The performance of each classifier is enhanced by using corresponding membership values of the data vectors as additional input variables. FCF is proposed as an alternate representation and reasoning schema to fuzzy rule base classifiers. The proposed method is evaluated by the comparison of experiments with the standard classifier methods using cross validation on test patterns.

    Object-Oriented Inheritance Metrics: Cognitive Complexity Perspective
    (Springer-verlag Berlin, 2009) Mishra, Deepti; Mishra, Alok
    Identifying high cognitive complexity modules can lead to a better quality software system and can help during maintenance also. It has been found that inheritance has an impact on cognitive complexity of a software system. In this paper, two inheritance metrics based on cognitive complexity, one at class level CCI (Class Complexity due to Inheritance) and another at program level ACI (Average Complexity of a program due to Inheritance), have been proposed for object-oriented software systems. These metrics are also compared with other well known object-oriented inheritance metrics.

    Measuring Complexity of Object Oriented Programs
    (Springer-verlag Berlin, 2008) Misra, Sanjay; Akman, Ibrahim
    In this paper, a metric for object oriented language is formulated and validated. On the contrary of the other metrics used for object oriented programming (OOPS), the proposed metric calculates the complexity of a class at method level and hence considers the internal architecture of the classes, subclasses and member functions. The proposed metric is evaluated against Weyuker's proposed set of measurement principles through examples and validated through experimentation, case study and comparative study with similar measures. The practical usefulness of the metric is evaluated by a practical framework.

    Modified Cognitive Complexity Measure
    (Springer-verlag Berlin, 2006) Misra, Sanjay
    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.

    A Tool To Enhance Cooperation and Knowledge Transfer Among Software Developers
    (Springer-verlag Berlin, 2009) Aydin, Secil; Mishra, Deepti
    Software developers have been successfully tailoring software development methods according to the project situation and more so in small scale software development organizations. There is a need to share this knowledge with other developers who may be facing the same project situation so that they can benefit from other people experiences. In this paper, an approach to enhance cooperation among software developers, in terms of sharing the knowledge that was used successfully in past projects, is proposed. A web-based tool is developed that can assist in creation, storage and extraction of methods related with requirement elicitation phase. These methods are categorized according to certain criteria which helps in searching a method that will be most appropriate in a given project situation. This approach and tool can also be used for other software development activities.

    Crm System Implementation in a Multinational Enterprise
    (Springer-verlag Berlin, 2009) Mishra, Alok; Mishra, Deepti
    The concept of customer relationship management (CRM) resonates with managers in today's competitive economy. As more and more organizations realize the significance of becoming customer-centric in today's competitive era, they embrace CRM as a core business strategy. CRM an integration of information technology and relationship marketing provides the infrastructure that facilitates long-term relationship building with customers at an enterprise-wide level. Successful CRM implementation is a complex, expensive and rarely technical projects. This paper presents the successful implementation of CRM in a multinational organization. This study will facilitate in understanding transition, constraints and implementation of CRM in multinational enterprises.

    Romberg Integration
    (Springer-verlag Berlin, 2003) Yazici, A; Ergenç, T; Altas, I
    Higher order approximations of an integral can be obtained from lower order ones in a systematic way. For 1-D integrals Romberg Integration is an example which is based upon the composite trapezoidal rule and the well-known Euler-Maclaurin expansion of the error. In this work, Mathematica is utilized to illustrate the method and the underlying theory in a symbolic fashion. This approach seems plausible for discussing integration in a numerical computing laboratory environment.

    A New Complexity Metric Based on Cognitive Informatics
    (Springer-verlag Berlin, 2008) Misra, Sanjay; Akman, Ibrahim
    In this paper, a new complexity metric based on cognitive informatics is proposed for object oriented(OO) code. This is the single metric, which covers cognitive complexity of the OO system, method complexity and complexity due to inheritance together. The proposed metric was evaluated against Weyuker set of measurement principles. It was found that seven Weyuker properties are satisfied by this measure.
