Expert System Model for Diagnosing Legume Diseases

Research Article of Research Journal of Mathematics and Computer Science Expert System Model for Diagnosing Legume Diseases Rahmon,I.A,Adebola_Akinsanya and Eze M.,. Computer Science Department Babcock University, Ilishan, Ogun State. There is a current surge in designing expert systems to solve problems like humans in different domains of research but there presently exist dearth of models that can guide designers of expert systems that can be used to accurately diagnose Soya beans diseases. Soya bean is a leguminous plant that is commonly grown in sub Saharan region and it is currently one of the legumes with high Gross Domestic Product (GDP) in the Nigerian economy, but farmers of this product are faced with serious challenges from legume ravaging diseases that are usually similar in symptoms and very difficult to diagnose by the few practising botanist available. Most models available cannot be used to guide designers who are interested in developing secured and reliable expert systems that can accurately classify, identify, diagnose and recommend treatments for Soya beans diseases. The main aim of this paper is to review existing models that are currently being used in designing expert systems and identify their limitations in other to come up with a better, more reliable and secured model. In other to identify inherent gaps from other models, research review method was adopted to critically investigate the weak points in few related and current expert models for classifying and diagnosing legumes diseases.

A Conceptual Design and Evaluation Framework for Mobile Persuasive Health Technologies (Usability Approach)

Research Article of Research Journal of Mathematics and Computer Science A Conceptual Design and Evaluation Framework for Mobile Persuasive Health Technologies (Usability Approach) Kasali, F. A.1, Awodele, O.2, Kuyoro, S.3, Akinsanya, A.4, Eze, M.5 1,2,3,4,5Department of Computer Science and Information Technology, Babcock University, Ogun State, Nigeria Persuasive techniques are recently being explored by computer science researchers as an effective strategy towards creating applications that are aimed at positive attitudinal changes especially in the health domain but finding effective evaluation approaches for these technologies remain an herculean task for all stakeholders involved and in order to overcome this limitation, the Persuasive System Design (PSD) model was designed but researchers claim that the model is too theoretical in nature and some of its design principles are too subjective as they cannot be measured quantitatively. Hence, the focus of this paper is to critically review the PSD model and popular models currently being used to evaluate the usability of information systems as usability has been identified as an important requirement currently used to evaluate the overall success of persuasive technologies. To achieve the stated objectives, the systematic review method of research was done to objectively analyze the PSD model, its applicability as an evaluation tool was tested on a popular mobile health application installed on the Samsung Galaxy Tablet using android Operation system. Exhaustive evaluation of the application was performed by 5 software usability researchers using the method of cognitive walkthrough. From the analysis, it was realized that the PSD model is a great tool at designing persuasive technologies but as an evaluation tool, it is too theoretical in nature, its evaluation strategies are too subjective in nature and the 28 principles described in it overlap with one another. As a result, the PSD model was extended with an integrated usability model and ...

WIDE WARM SURFACE CURRENTS IN MOST OCEANS

Review Article of International Journal of Natural Science and Reviews WIDE WARM SURFACE CURRENTS IN MOST OCEANS Kern E. Kenyon 4632 North Lane, Del Mar, USA Since a wide warm surface current, permanently flowing northeast off California, has been documented with all the available data that could be found plus helping to organize the collection of a new set of observations has happened, a search was carried out for a similar circulation feature in other oceans. Very likely there exists a wide warm surface current in the South Pacific moving southeast from the middle of the ocean and impinging on the coast of South America. In the South Atlantic a wide warm surface current appears to go south in the western half of the basin. Contained in the North Atlantic is “the large volume of warm water outside the Gulf Stream drifting north”, which was first described by Maury and confirmed recently by newer measurements. A puzzling SST observation in the northwest Indian Ocean, that in a given year two summers and two winters occur, is explained by a hypothesis that is a bit more complicated than shown by the surface currents in the other oceans. For confirmation more surface and near surface measurements are needed. Keywords: Wide Warm Surface, Most Oceans ...

Rationale and risks of non-audit services

Research Article of Journal of Theoretical and Applied Economics Rationale and risks of non-audit services You Yu With changing conditions of the financial environment, relative issues of non-audit services still require further developments and researches, concerning their rationale and risks that can be admitted so far, and influences of latest regulations. Here the rationale and risks of NAS were investigated through summarizing prior studies. Some researchers believe that there is a trade-off effect between advantages and disadvantages of NAS, therefore, it can be accordingly concluded that there is at least net effect in NAS’s downsides and upsides, the rationality of NAS can be prove based on this sight. However, many latest researches tend to believe NAS has adverse impacts. Keywords: Rationale, risks, non-audit services, advantages, disadvantages [rml_read_more] ...

Service Quality Measurement Models: a Comparison of Two Models

Research Article of Journal of Theoretical and Applied Economics Service Quality Measurement Models: a Comparison of Two Modelsea Asmerom A. Ghebremichael1 and Fitsum Ghebregiorgis2 1 Department of Accounting at College of Business and Economics, Department of Accounting (Previously at the University of Asmara. Now under the umbrella of the National Commission for Higher Education, Eritrea) 2 Department of Business Management and Marketing at College of Business and Economics, Department of Business Management and Marketing (Previously at the University of Asmara. Now under the umbrella of the National Commission for Higher Education, Eritrea) Purpose of this paper – This study aims to contribute to the debate in service marketing literature concerning the operationalisation of service quality measurement. To this effect, we tested two service quality measurement models by adapting them to the audit service context. These models are the gap model (SERVQUAL) developed by Parasuraman, Berry, and Zeithaml (1985) and the performance-only (SERVPERF) model developed by Cronin and Taylor (1992). Design/methodology/approach – The models are quantitatively analysed and evaluated for construct validity and predictive power using OLS models. In line with marketing literature (Gronroos 1984), service quality dimensions are classified into technical and functional dimensions. Construct validity is measured in terms of whether the technical and functional dimensions of audit service quality are significantly positively correlated with an overall measure of service quality in the audit service market. Predictive power is measured in terms of the strength of adjusted R2. Findings – The results indicate that both the performance-only model and the gap model have done quite well in predicting determinants of overall audit quality. The argument by Cronin and Taylor (1992) that the gap model has low explanatory power compared to the performance-only model did not materialise in our study. Research limitations/implications – Our results are limited by the low ...
