A model of case implementation and an experience of unsuccessful case adoption

Computer-Aided Software Engineering (CASE) is a revolutionary technology that seeks to automate the software development process. Current literature reports on many successes of CASE adoption Despite of such successes, many organisations are experiencing difficulties in implementing CASE technology . Even many powerful CASE tools have become 'shelfware'. It is argued that the benefits of CASE are unlikely to be realised, unless it is introduced based on a sound implementation plan This article presents a conceptual model to introduce CASE technology within a MIS department Such a plan faciliiaus change in software culture and management practice and enables management to deal with confusion and skepticism prior to its occurrence. Furthermore, a case study is described that focuses on a CASE implementation that failed to achieve its purpose The reasons for the failure are critically examined and explained in the light of the model

Mobile agent routing for query retrieval using genetic algorithm

Mobile agents often have a task to collect data from several predefined sites.This should be done in an efficient way by minimizing the elapsed time.Usually these agents only know the list of sites but not the distances between them.This paper proposes a method to minimize a network routing time taken by the mobile agents to collect information from different sites using genetic algorithm (GA).The mobile agents repeat travelling over short routes and avoid longer ones.Mobile agents for query retrieval have used the GA to select the best routes that minimize the query retrieval time.The result shows that the proposed method provides good time minimization in retrieving the query results by the mobile agents based on different GA parameters

Effect of extraction methods on yield, oxidative value, phytosterols and antioxidant content of cocoa butter

Cocoa beans are rich in numbers of beneficial bioactive compounds such as phenolics and phytosterols, which benefits to human being. The suitable extraction method is needed to produce high quality and quantity of cocoa butter and other bioactive compounds. There are many extraction method to extract these compounds such as Soxhlet extraction, supercritical fluid extraction, ultrasound extraction method and others. The objective of this study is to determine the effectiveness of the different extraction methods producing high yields of cocoa butter, lower oxidative value, stable phytosterols and antioxidant content. The cocoa beans were subjected to different extraction methods such as Soxhlet extraction (SE), Ultrasonic extraction method (USE), Supercritical carbon dioxide (SCO2) and Supercritical carbon dioxide with co-solvent (SCO2-Ethanol). Cocoa butter extracted using SCO2-Ethanol has significantly (p<0.05) obtained highest cocoa butter yield (37.05%) and phytosterols content (6441 μg/g of extract) compared to SE (28.87% and 4960 μg/g of extract), SCO2 (31.32% and 5492 μg/g of extract) and USE (34.81% and 5106 μg/g of extract). Meanwhile, the oxidative value of SCO2-Ethanol was significantly (p<0.05) obtained lowest value compared to other extraction methods. Extraction method are crucial in cocoa industry to minimise the cost during processing, obtain maximum extraction yield and preserve the bioactive compounds thus will improve the value of cocoa butter improve the value of cocoa butter

Carbon-Polyol Coating Using Carbon Produced From Palm Kernel Cake (PKC)

In our quest to create awareness in using renewable, sustainable natural resources and efficient waste management, palm kernel cake (PKC) which is the waste from the palm industries was used in preparation of Carbon-polyol coating. PKC was subjected to pyrolisis process and the carbon residue obtained was used as a black pigment. In this work modified Polyol was used as the binder for its ideal properties as vehicle to produce good opacity of paint. Various carbon-polyol dispersant with different weight compositions (wt%) of carbon prepared and tested against its respective rheological properties in order to determine ideal paint/ink system. Two different types of paper material (Brown paper B and white paper W) were chosen as a substrate and characterised. Each of the paper was then proofed with Carbon-polyol using palm kernel carbon (PKC) and commercial carbon (PURE_C). Lightfastness test was carried out on the paper specimens and the results on the total colour difference (dE) are obtained. It was found that the total colour change (dE) in specimens using brown paper (B) coated with Carbon polyol coating using carbon derived from palm kernel carbon (PKC_B) and the commercial carbon (PURE_C_B) is within 10%. The other two specimens, using white paper (PKC_W and PURE_C_W), the total colour change (dE) is 17%. It is expected that the coating system has the potential application in paint or ink.

Arabic web page clustering: a review

Clustering is the method employed to group Web pages containing related information into clusters, which facilitates the allocation of relevant information. Clustering performance is mostly dependent on the text features' characteristics. The Arabic language has a complex morphology and is highly inflected. Thus, selecting appropriate features affects clustering performance positively. Many studies have addressed the clustering problem in Web pages with Arabic content. There are three main challenges in applying text clustering to Arabic Web page content. The first challenge concerns difficulty with identifying significant term features to represent original content by considering the hidden knowledge. The second challenge is related to reducing data dimensionality without losing essential information. The third challenge regards how to design a suitable model for clustering Arabic text that is capable of improving clustering performance. This paper presents an overview of existing Arabic Web page clustering methods, with the goals of clarifying existing problems and examining feature selection and reduction techniques for solving clustering difficulties. In line with the objectives and scope of this study, the present research is a joint effort to improve feature selection and vectorization frameworks in order to enhance current text analysis techniques that can be applied to Arabic Web pages

Effect of organic acid ingredients in marinades containing different types of sugar on the formation of heterocyclic amines in grilled chicken

The aim of the study was to determine the use of alternative organic acids in formulating marinade ingredients to reduce heterocyclic amines (HCA) in grilled chicken (satay). Samples were marinated with table sugar, brown sugar, and honey with the addition of tamarind, lemon, lime, and calamansi for 24 h at 4 °C. The pH readings before and after marinating were measured. HCA concentrations before and after grilling were quantified. There was a significant difference (p<0.05) in the combined HCAs among the control and marinated grilled chickens. Using lemon in marinades containing table sugar, concentrations of DiMeIQx were significantly reduced (p < 0.006) from 16.5 ng/g (low) to 8.30 ng/g for (high) concentrations of organic acid ingredients. The mean pH of the treated samples was significantly lower (p<0.05) than in the control samples. Calamansi was found to reduce HCAs in marinades containing table sugar and brown sugar, whereas tamarind in marinades containing honey

Digital crime inflicts immense damage to users and systems and now it has reached a level of sophistication that makes it difficult to track its sources or origins especially with the advancements in modern computers, networks and the availability of diverse digital devices. Forensic has an important role to facilitate investigations of illegal activities and inappropriate behaviors using scientific methodologies, techniques and investigation frameworks. Digital forensic is developed to investigate any digital devices in the detection of crime. This paper emphasized on the research of traceability aspects in digital forensic investigation process. This includes discovering of complex and huge volume of evidence and connecting meaningful relationships between them. The aim of this paper is to derive a traceability index as a useful indicator in measuring the accuracy and completeness of discovering the evidence. This index is demonstrated through a model (TraceMap) to facilitate the investigator in tracing and mapping the evidence in order to identify the origin of the crime or incident. In this paper, tracing rate, mapping rate and offender identification rate are used to present the level of tracing ability, mapping ability and identifying the offender ability respectively. This research has a high potential of being expanded into other research areas such as in digital evidence presentation
