    The creations of models are essential for many knowledge disciplines to explain expected results. Modelling concept is well accepted in software engineering discipline. Some software models were built either to control the development stages or to serve as a medium that gives better understanding of the actual software systems. However, there is still a lacking of software process measurement being discussed and explored by software engineers. An aim of this research is to integrate measurement in software process modelling, to show that measurement in modelling software processes is important whereby to reduce flaws in developing large software. Software process modelling has reached the level that allows software designs to be transformed into programming languages. Examples of such approaches are architecture design language (ADL) and unified modelling language (UML). Selecting a modelling technique is essential to the designers and the selection depends on the needs of the system. This research focused on IDEF3 Standard notation as its approach to design software process models. The language syntax provided by IDEF3 standard have been modified and enhanced to suit the aim of the research. This new version of IDEF3 context-free grammar is named IDEF3-SPMA language. IDEF3-SPMA language constructs and measurement metric defined in this research has been verified using attribute grammar approach. A prototype tool for automatic process model metrics calculation namely Software Process Measurement Application (SPMA) is developed to realize the definitions defined. SPMA system counts the particulars of a process model design and output a list of measurement values. Inference metrics and appropriate advices are also stated to indicate the use of the metric values. Testing and verification results indicated that with a standard notation of performing a software process model designs, the structure and relationship between processes could be clearly seen. This research also shows that automatic calculation of process model design measurement is possible using a well-defined language specification and a specific calculation tool. Several measurement metrics produced by SPMA system are such as number of calling subprocesses in the design, number of sub-junction processes and the size of a process structure.It is concluded that this research has produced an environment consisting of design notation, language constructs, a tool that enabled measurement metrics to be calculated automatically, metric inferences and appropriate advices. The specification of measurement metrics definition using attribute grammar, the SPMA tool, metric inference and metric advices are contributions of this researc

    Web Access Analyser for Distance Education Environment

    Distance Education implementation has been greatly influenced by the changing of the current sophisticated technologies. Internet and World Wide Web (WWW) have enabled the rapid growth of distance education technology. The Internet is a huge database that connects most of the information source centers worldwide. This technology is equipped with the existence of WWW that ease accesses to the sources. With these technologies, distance education can be implemented properly. An approach been developed is the implementation of distance education through WWW. Learning modules are kept in a Web server while the student can access the modules from scattered terminals linked to the server via the network. It is a method of module delivery to the students that which are easier and faster. Even though distance education requires individual capability to manage the time and learning effort, the educators still have the responsibilities in evaluating their students' achievements. It is easier to evaluate on-campus students compared to distance learners. If the educators can evaluate on-campus students through their attendance and work performance, an appropriate approach to evaluate out-campus students' effort and commitment is necessary. There is a file that is specially created by a Web server which keeps and lists all access requests and transaction information made to the files kept within the server. This particular file is known as an "access_log" file. There has been a substantial effort to manipulate the file, for example, this study used "access_log" file to filter out information to produce students' distance module access statistics which is able to assist distance educators to evaluate distance students' commitment as well as to measure modules' design efficiency

    Food is one of the essential human needs and Muslims are obligated to consume the halal food. Nowadays, there are numerous food products available in the market, which the actual contents of these products sometimes are not clear. Non-halal ingredients such as pork, lard, gelatine, alcohol (khamr) and blood are commonly found in the food products. Adulteration is also one of the common issue over the world. Adulteration is the act of intentionally mix or substitution the product with either similar or cheaper ingredients. Therefore, scientific analyses are become very important to authenticate the adulteration in food products. For instance, some analytical techniques have been used and continuously developed for the authentication of halal food products such as chromatography-based methods, Fourier transform infrared (FTIR), electronic nose (E-nose), differential scanning calorimetry (DSC) and DNA-based methods. Hence, this review attempts to emphasis the progress and challenges associated with halal food authentication

    Going Beyond Counting First Authors in Author Co-citation Analysis

    Full text link
    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed

    Requirement traceability matrix through documentation for SCRUM methodology

    Full text link
    Requirement traceability matrix is a table that captures the complete user and system requirement for the system. It helps to trace from requirement till testing in order to verify that the requirement is fulfilled. In SCRUM development methodology, requirement traceability matrix is used to capture the linkage of user stories between product backlog and sprint backlog. The linkages between the requirements are retrieved through these two documents. However, unstructured format of both documents do not help in getting the requirement traceability. Thus, requirement traceability has become an issue for SCRUM practitioners especially for system development and maintenance. Therefore, this study will introduce structured format of available artifacts and develop a tracing tool to automatically generate the requirement traceability matrix by keyword searching. Both the documents used in this study have to be prepared by using the structured format and the proposed traceability tool is able to generate the requirement traceability matrix automatically by keyword searching functionality. The result shows that the introduced structured format is very useful and it has increase the efficiency of retrieving the matrix far better than previous process. There is a significant time saved up to 95% for generating the requirement traceability matrix using the proposed method and tool. As a conclusion, requirement traceability can be achieved in SCRUM methodology through the proposed structured documentation and the tool developed

    Variations on the Author

    “Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship

    Appropriate Similarity Measures for Author Cocitation Analysis

    Full text link
    We provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis

    Data integration in scientific experiments is important to the scientists in many research domains. This is because many experimental data involved multidiscipline areas and run in different machines or instruments which results in data stored in different ends and human intervention is required in forming a chain of data analysis. Ontology is one of the approaches that have been used in data integration in many domain areas. This paper described and reviewed ontology in data integration effort. Furthermore, the state of research for ontology-based integration of scientific experiment data also covered in this paper
