Investigation and assessment of bamboo as a construction material (Part 1) https://www.ajol.info/index.php/wajiar/article/view/161475 <p>The shortage of housing in developing countries motivated the search for low cost construction sustainable materials that can be applied in the construction of affordable houses in this context; researchers have been studying the application of the locally available natural materials as building material as blocks, reinforcement, soils, and cement. The understanding of working with bamboo has caught the attention of Engineers, architects and material researchers due to its great potential as a construction material. This study attempts to investigate and assess bamboo as a construction material, benefits, Veritable investment for low and high income earners, bamboo applications, and its characteristics. The study provides recommendation and conclusion which befit the subject matter under consideration.</p><p><strong>Keywords:</strong> investigation, assessment, bamboo as a construction material</p> A.J.

Diagnosis of disease must be done with care since it is the first stage of therapeutic actions towards eventual management of the disease; a mistake at this stage is disastrous and such adequate care must be ensured. Diagnosis becomes difficult in medical domain due to influence of medical uncertainties that arises from confusability in disease symptomatic presentation between two diseases. This confusability of these diseases stems from the overlaps in the disease symptomatic presentation and has led to misdiagnosis with various degrees of associated costs and in worst cases led to death. In this research, we present the analysis of the existing systems and finally present a framework for the diagnosis of confusable disease using neutrosophic-based neural network.</p><p><strong>General Terms:</strong> Clinical Decision Support System, Medical Diagnosis, Machine Learning, Soft Computing.</p><p><strong>Keywords:</strong> Decision Support System, Medical Uncertainties, Neutrosophic Logic, Confusable Diseases</p> Okpako Abugor Ejaita P.O.

In Nigeria the awareness has increased but adoption is yet to follow the level of awareness. The key de-motivation towards full adoption include proper understanding of the concepts, initial costs and the fear of compromised data integrity when strategic information is trusted in the hand of a third party. Apart from integrity of data comprose, the other key factors inhibiting adoption is the cost of monthly subscription mostly in US dollars. This paper has considered the cost of establishing a local cloud service to serve surrounding organizations. The paper contends that indigenous ICT firms should develop the capacity to incubate cloud services as this will go a long way to encourage adopters and save organizations from excessive ICT budget.</p> O.E.

I was motivated by the challenges faced by the Nigerian military who have labour onerously to put a stop to the menace of the terrorist group “Boko Haram” but while having achieved some measure of success, are ambushed and killed by terrorists as a result of possible information leakage or intellectual property theft. The methodology adopted is Prototyping and the expected result is a correlation coefficient that will show level of similarity of Hexadecimal codes contained in the microcontroller of the equipments under test.</p><p><strong>Keywords:</strong> Backdoor, Hardware Backdoor, Correlation Coefficient, Read Time Analysis</p> C Olebra O.E.

In this work we combined page rank crawling method and depth first crawling method to create a hybridized method. Our major objective is to unify into one search system, the page rank method and the depth first crawling method to get into crawling the web at an efficient rate for a better recall and precision. The page ranking and depth first systems respectively are aimed at producing increase recall and ranking backlinks of a query to a matched document. The unification now is to help produce additionally, the most authoritative pages in a search result, thereby increasing the precision thereof. The methodologies adopted are the document and query likelihood models. Documents or corpora of known measures in query types, recalls and precision from the Text Retrieval Conference (TREC), the Initiative for Evaluation of XML retrieval (INEX) and REUTERs collection, were used as work bench for evaluation of the system. The results obtained showed significant improvement from results if implemented using the depth-first method and page ranking method as a single entity.</p><p><strong>Keywords:</strong> Page Rank, Authoritativeness, Outbound link, Inbound link, Depth-First, crawling</p> Anigbogu Kenechukwu Samuel Okide Gloria Anigbogu Copyright (c) 2017-09-20 2017-09-20 18 1 33 39 Thermo-feasibility optimization of multiple feed rate multicomponent distilation system https://www.ajol.info/index.php/wajiar/article/view/161480 <p>Thermoexergetic rate profile, thermoexergetic-efficiency and thermoexergetic-destruction were used in combination with the view to determine the thermo-feasibility of multicomponent distillation system with multiple feed rate. Simulation was of a multicomponent distisllation system was carried out and the stage-by-stage system exergy analysis was carried out. Multiple feed rate base cases sensitivity results gave the most adequate and feasible thermo-exergetic rate profiles, efficiency ranges and destruction at the depropanizer and debutanizer. Overall system performance of multiple feed rate base case -30 <sup>o</sup>C design gave optimum overall system exergy destruction and efficiency. Multiple feed rate could ensure thermo-feasibility of the system and this can form basis for system performance and productivity improvement.</p><p><strong>Keywords:</strong> Thermoexergetic-rate, thermo-feasibility, thermoexergetic-efficiency, thermoexergeticdestruction, multicomponent-distillation, multiple feed rate</p> K.A.

In this work, we arrive at the drift and the volatility by observing the dynamics of change in the selected stocks in a sufficiently small interval <span>△</span><em>t</em> . We assumed that only one change occurs within <span>△</span><em>t</em> = <em>t</em><sub>i+1</sub>-<em>t</em><sub>i</sub> . During this time, a stock may gain one unit [+1], remain stable [0], or loss one unit [-1]. The likelihood of each change occurring were noted and the expectation (the drift) and the covariance (the volatility) of the change were computed leading to the formulation of the system of linear stochastic differential equations. To fit data to the model, changes in the prices of the stocks were studied for an average of 30 times. A simple checklist was used to determine the likelihood of each event of a loss, again or stable occurring. The drift and the volatility coefficients for the SDE were determined and the multi-dimensional Euler-Maruyama scheme for system of stochastic differential equations was used to simulated prices of the stocks for 1 <span>&lt;</span> <em>t</em> <span>&lt; </span>30 . The simulated prices was compared to the observed price and we observed that the simulated prices is sufficiently close to the observed price and there for suitable for forecasting the price of the stocks for a short time interval.</p> O.I.

The dynamic relationships between the stock price movement and the macroeconomic variables were reviewed. This problem of predicting direction of movement of stock and stock price index was addressed.</p> I.C. Okereke A.I.O. Ofomata S.O.

It goes further to establish that in an infinite dimensional commodity space with subsets as consumption and production set there exist a price system. The compactness and convexity properties of these two disjoint sets enables us to establish this price system in this infinite dimensional space via the existence of set of continuous linear functional. This price system becomes the competitive equilibrium price and allocation which maximizes and minimizes the cost function for producers and consumers respectively</p><p><strong>Keywords:</strong> Competitive equilibrium, commodity space, functional, agents and price system</p> I.C.
