In this study, the level of service of selected major road intersections in Ibadan were investigated. Traffic volume of each intersection approach was conducted from 7am 7pm on Mondays, Wednesdays and Saturdays, delay studies were carried out during the morning, afternoon and evening peak hours and level of service for each approach was determined from the average delay per vehicle. The traffic volume reveals that passenger cars are the predominant vehicles at all the approaches and the morning and afternoon peak hours occurred between 8 to 9am and 2 to 3pm, respectively. The level of service for all the approaches is B, indicating slight reduction in capacity of the intersections.","PeriodicalId":440930,"journal":{"name":"Journal of Information Engineering and Applications","volume":"12 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133208330","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The liquid limit decreased and plastic limit increased while there is a reduction in corresponding plasticity index of the clay soil. There was an increase in Maximum Dry Density (MDD) and Optimum Moisture Content (OMC) of the stabilized soil sample, which increased with the increasing content of CCA and cement. Both the Unconfined Compressive Strength (UCS) and California Bearing Ratio (CBR) of the soil increased with increasing percentage of cement and CCA. Based on the results of this study, corn cob ash (CCA) cannot be used as a stand-alone stabilizer for this lateritic soil but with a more potent stabilizer for clay soil such as lime. It is therefore recommended that the mixture of 12% CCA and 2.5% cement could be used to stabilize A-7-5 (10) lateritic soil for use as subbase material and 12% CCA and 5.0% cement could be used to stabilize A-7-5 (10) lateritic soil for use as base material for improving pavement structure in terms of strength, 9 % for 0 to 5% cement and then increased. The decrease in the percentage fine content up to 9% results from the flocculation and agglomeration of soil-CCA mixture coupled with pozzolanic reaction between cement and CCA which both produce hydrated calcium silicates (CHS) and hydrated calcium aluminates (CHA) which act as binder for the fine particles within the soil and hence reduction in the fine content as the percentage CCA increases.","PeriodicalId":440930,"journal":{"name":"Journal of Information Engineering and Applications","volume":"33 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117102966","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Traditional contracts can take weeks or even months to initiate, and there have been numerous instances of breaches and lack of trust for contracts in both the private and public sector. A smart contract can be defined as a self-executing contract that utilizes blockchain technology to digitally enforce, verify, or facilitate the performance or negotiation of a contract. Owing to the security and decentralized system exhibited by blockchain technology, smart contracts can foster transaction credibility between contracting parties without the necessity of third parties as exhibited in traditional contracts. Any business organization that aims at achieving greater heights in management and production dimensions must consider utilizing robust technologies that are aimed at bolstering its competitive edge. Owing to the newness of smart contracts, characterized by very few studies on the same, this research reviews how smart contracts through blockchain technology can be implemented in an organization to enhance performance and outlines the applications, benefits, and limitations associated with such contracts.

Minority classes in the datasets are treated as outliers’ classes. The research aimed at establishing the role of ensemble technique in improving performance of multiclass classification. Multiclass datasets were transformed to binary and the datasets resampled using Synthetic minority oversampling technique (SMOTE) algorithm. Relevant features of the datasets were selected by use of an ensemble filter method developed using Correlation, Information Gain, Gain-Ratio and ReliefF filter selection methods. Adaboost and Random subspace learning algorithms were combined using Voting methodology utilizing random forest as the base classifier. The classifiers were evaluated using 10 fold stratified cross validation. The model showed better performance in terms of outlier detection and classification prediction for multiclass problem. The model outperformed other well-known existing classification and outlier detection algorithms such as Naive bayes, KNN, Bagging, JRipper, Decision trees, RandomTree and Random forest. The study findings established that ensemble technique, resampling datasets and decomposing multiclass results in an improved classification performance as well as enhanced detection of minority outlier (rare) classes.

Examples of such tasks include syndrome differentiation, likelihood survival for sickle cell anaemia among paediatric patients, diagnosis and optimal selection of medical treatments and real time monitoring of patients. For this paper, a Fuzzy logic-based system is untaken used to provide a comprehensive simulation of a prediction model for determining the likelihood of detecting Chronic Kidney failure/diseases in humans. The Fuzzy-based system uses a 4-tuple record comprising of the following test taken: Blood Urea Test, Urea Clearance Test, Creatinine Clearance test and Estimated Glomerular Filtrate rate (eGFR). Understanding of the test was elicited from a private hospital in Ibadan through the help of an experienced and qualified nurse which also follows same test according to National Kidney Foundation. This knowledge was then used in the developing the simulated and rule-base prediction model using MATLAB software. The paper also follows the 3 major stages of Fuzzy logic. The results of fuzzification of variables, inference, model testing and defuzzification of variables was also presented. This in turn simplifies the complication involved in detecting Chronic Kidney failure/disease using Fuzzy logic based model.

In this study, the authors explored a narrative review that focuses on the theoretical underpinnings of vast works of literature that revealed significant information on the conceptual framework, existing systems that adopt BYOD security, analysis, and synthesis of prior research. Using some keywords “BYOD system security”, “BYOD security threats”, “cyber-attacks and security”, etc., an electronic database search extracted peer-reviewed articles from the last five years. The thematic analysis of fifty-one articles retrieved revealed that breaches and fraudulent activities exist with the use of BYOD that may be perpetrated against organization’s data, intentionally or maliciously. Good policies and guidelines on the use of BYOD coupled with good formulation and communication of same, should be adhered to avert some forms of security breaches. There is the need to preserve user’s privacy, organizations’ data confidentiality, integrity, and availability, and secure same in the devices of employees using their own devices to process corporate and personal data, by using acceptable and effective BYOD Policy and Mobile Device Management Solution (MDMS). This may increase mutual trust and BYOD adoption rate, new innovations and influence that can positively impact the organizations and their employees.

According to Nigerian treatment guidelines, it is estimated that about 23 million people in Nigeria are currently affected with the disease. It is a key world-wide health problem. This paper is necessitated with the need to develop a fuzzy logic-based model for proper diagnosis of the virus hepatitis B using blood tests. An extensive interview was conducted with a licenced medical personnel at the federal polytechnic Ile Oluji medical centre located at Ondo state, Nigeria. A fuzzy logic-based system is untaken which is used to simulate the diagnosis of hepatitis B in humans using 3-turple record which are HBsAg (Hepatitis B surface antigen), anti-HBs or HBsAb (Hepatitis B surface antibody) and anti-HBc or HBcAb (Hepatitis B core antibody). Triangular membership function were used to fuzzify both inputs and outputs while the fuzzy inference engine was used to develop the rules using MATLAB fuzzy logic toolbox software. The model will help in proper diagnosis of the virus and steps to be taken for treatment. ACM CCS (2012) Classification : 1.
