Introduction: Business Intelligence Systems (BIS) are the most potential application for many popular organizations in different industries such as telecommunication, healthcare, airline, transport, government and others. The implementation of Business Intelligence (BI) for Institutions of Higher Learning (IHL) is still at the early stage for most IHL organizations. Results of previous studies have found that more than half of BI projects fail to meet their objectives even though a lot money is spent. Based on that problem, it is important to identify the readiness level of BI for IHL in order to reduce the risk before the actual BI project is implemented. In this paper, a rigorous literature review on success factors such as Critical Success Factors (CSFs), Readiness Factors (RFs), Success Factors (SFs) are discussed by different authors.

Aims: The aim of study is the Business Intelligent Readiness Model (BiRM) as a guild for IHL before implementing the BI system.

Study Design: For this study, semi-structured interviews will be chosen as a method of collecting relevant qualitative data to explore and refine the model of BI readiness model for IHL in Malaysian. Here, the list of themes, issues to be addressed and questions to be asked were identified and pre-defined by the researcher. The use of semi-structured interviews ensures that information is captured from the respondent’s perspectives rather than being imposed by the researcher.

Place and Duration of Study: The study will be conducted at Malaysian Institutions of Higher Learning (IHL). This study is expected to finish within a 12-month period.

Methodology: The study is proposed to be conducted through a mix of methodology comprising qualitative and quantitative methods, including interviews and observations with a range of stakeholders such as ministry officers, computer centre managers, technicians and the end users from different IHL in Malaysia.

Results: The result of the data collection will be analyzed using the causal modelling approach of SEM SmartPLS for the validity and the relationship between construct. The expected finding from this research is the Business Intelligent Readiness Model (BiRM) as a guild for IHL before implementing the BI system.

Zygophyllum coccineum L. (Family Zygophyllaceae) was collected from two locations namely Wadi Hagul and Deltaic Mediterranean coast. Methanol, acetone and ethanol extracts prepared from Z. coccineum leaves and they were tested for their antibacterial activity. The bacterial strains tested were Escherichia coli, Bacillus subtilis, Staphylococcus aureus, Bacillus cereus, and Pseudomonas aeruginosa. Methanol extract from desert plant was the most potent extract against bacterial growth compared with other extracts. Also, the three extracts expressed antifungal activities against the tested fungi Candida albicans, Aspergillus niger and Aspergillus flavus. Methanol extract from the desert plant was the strongest in retarding the fungal growth. The aqueous leaf extract of Z. coccineum from both desert and coastal areas inhibited seed germination and radical growth of Chenopodium album at 50 and 100 µgml-1. The inhibition rate was remarkable with the desert plant compared to that of coastal one and this may be due to the higher contents of bioactive compounds.

The paper aims at studying the strength characteristics of steel fibre reinforced concrete (SFRC), within the fibre dosage of 0.5 to 2%. Discontinuous discrete steel fibres were explored in concrete of grade M60, and normal concrete of 0% steel fibre dosage used as control. The concrete behavioural properties were investigated under compression at 3, 7, 14, 21, 28, 90 and 120 curing days. Steel fibre reinforced concrete sample with highest compression yield were further examined under tension and flexure respectively.

The findings revealed that, the addition of steel fibre to concrete improve the strength properties of the concrete, with better performance under compression, tensile and flexure compared to control concrete. The SFRC specimens were observed to yield a percentage increase of 3.96-10.54% in compression, 49.83-97.08% in tension and 13.63-28.27% flexural compare to the control. The presence of steel fibre was also observed to minimize crack propagation over conventional concrete, which shows that steel fibres helps in better bonding of the concrete and displays steel fibre reinforced concrete as to possess good ductility properties.

The maker is the pioneer of open source, and the open hardware is the essential tools for the makers. As the typical representative of the open hardware, Raspberry Pi has been widely applied in open source since 2012. Z notation is a formal specification language based on the set theory and the first order predicate logic. So the Z notation can improve the reliability and robustness of the computer system using strict mathematical theory. This paper accomplishes a technical explanation of the concept of open hardware and the organization of the Raspberry pi via utilizing the Z notation. The Z notation of Raspberry pi is more precise and more systematic compared with the other informal specification. This research has great significance for the large-scale popularization of Raspberry pi and open hardware development.

Identification of microorganisms is central to the study of microbiology at all levels of research. The methods employed are also important. It is however very pertinent that scientists the world over continuously improve on the method of microbial identification for greater efficiency. A study was conducted to isolate and identify Bacillus species from some ready-to-eat (RTE)/convenience food samples. The Bacillus species isolated were identified by using the classical method. The same isolates were further identified via use of the 16SrDNA sequencing method.The classical method identified all bacilli isolates as members of a precise species in the genus Bacillus, but with discrepancies observed in 3 out of 9 identified cases (33.3%) when comparison was made with PCR/sequencing method. PCR/sequencing method provided results which were in accordance with both classical and genotypic identification in more than 70% of cases.This study emphasized the presumptive nature of classical methods in identifying Bacillus species/strains, without further recourse to the use of more sensitive and molecular methods. Identities from the PCR method hold greatest sway and are regarded as most reliable as it involves the analysis of genetic sequences of this group of microorganisms.

In this paper a Decision Support System named W8st colSoft is developed by employing dynamic programming and swarm intelligence model encoded in Visual Basic Studio 10.0. Solved solutions from literatures were used to validate the developed decision support system. The results obtained from these validation presented an average error margin of 2.58% when compared with that from literature. Also, in order to present the scalability of the swarm intelligence model employed in the developed decision support system, it was used as a decision tool to analyze the collection of solid waste of the University of Port Harcourt three campuses as a whole, unlike recent publication where it was analyzed Campus-wise. The resultant optimal path from the analysis presented a total distance of 15,682 m saving a total distance of 17.15 m when compared with other route options. Additionally, an Evolutionary Algorithm in Microsoft Excel 2013 was applied to the University of Port Harcourt four campus segments and the results were compared with those of the Proposed model. The percentage error margin between Evolutionary Algorithm and the Proposed model prediction ranges from -0.34 to 11.27. The Proposed model was able to achieve optimum value with minimum number of iterations in all cases and this is an advantage.

The main goal of present study is to experimentally and analytically investigate the behavior of indirect loading, deep flanged reinforced concrete (RC) beams. The load is applied via shear on the side arms of the beam with bearing plates. Eighteen reinforced concrete deep T- beams designed to fail in shear. The beams without web reinforcement were tested under indirectly loading conditions. The beams were divided into three groups according to the ratio of shear span to effective depth. The specimens had different flange depth and flange width in order to investigate the effects of flange dimensions. The behavior of beams was observed; cracking load, ultimate loads, concrete strain, deflections and crack widths. Experimental results indicate that the indirectly loaded deep beams can carry additional loads after diagonal cracking.

The study includes numerically predicted the Ultimate Loads carrying capacity with strut-and-tie method (STM) which is based on the ACI Building Code (318-08). The prediction results of ultimate shear capacity for (STM) models are agreed with the experimental finding. As well as the performance of the beams conformed with 3D non-linear finite element analysis that involves discrete reinforcement modeling. This modeling process is performed by using ANSYS 12.1 the prediction results of ultimate shear capacity for Ansys models are agreeing with the experimental finding. Furthermore, the experimental results were compared with prediction data used the equation for ordinary beams that recommended by ACI Building Code (318-08). It was concluded that the ACI Code equation underestimated the concrete shear strength of the single span indirectly loaded Flanged deep beams.

In this research, one-dimensional steady state thermal structure in part of Niger Delta sedimentary basin has been modelled using one layer model. The solution to the Fourier one dimensional heat flow was used to generate geotherm the area. The model column is about 7.0 Km thick, has average thermal conductivity and radioactive heat generation of 2.5 Wm−1 C−1, and 2.0 µWm-3 respectively. Two boundary conditions; surface temperature and heat flow of 27oC and 50mWm2 were also used. The computed temperatures using the model increases with depth from earth surface to about 6500 metres. Beyond 6500 metres, the temperature starts decreasing with depth as a result of the quadratic nature of the model. The depth range within which the temperature increases with depth falls within the Benin and Agbada Formations of the Niger Delta. Comparison between the computed temperature and measured bottom hole temperature from three wells reveal a very good matched. The diference between computed and measured temperature ranges between -4.0 to 6.0°C. The thermal structure of the sedimentary basin is controlled by thermal conductivity and radiogenic heat production.

DOI: 10.9734/BJAST/2016/25752

Background: The study examines the spatial distribution of low birth weight by the ten administrative Regions in Ghana using Area to Point Kriging method. Low birth weight babies, defined by World Health Organization as babies born at term who weigh less than 2.5 kg is an important indicator of reproductive health and general health status of population. The incidence of LBW is quite high in the sub region which has a public health concern.

Methods: The study used a data set based on a Multiple Indicators Cluster Survey conducted by Ghana Statistical Service in 2011 with a sample of 10,963 women within the reproductive age. The geostatistical analysis applied in this study consists of three steps: filtering of noise in the data based on Poisson kriging, mapping of the corresponding risk at a fine scale and estimating geographical clustering of the low birth weight at the administrative units

Results: This study has demonstrated how geostatistical method can be used to model low birth weight incidence by administrative units. The Area to Point method employed has given an insight into a more localized potential “hot spots” for low birth weight incidence. The research showed a large range of spatial autocorrelation in the northern part than in the south in the incidence of low birth weight. The risk associated with low birth weight is centred broadly in the northern districts, districts in Central region and districts in the southern part of Ashanti region in the country which coincidentally are dominated by people of Sissala, Kassena, Mamprusi, Mole Dagbani, Wassa and Akan descends.

The least affected areas are those settlements along the Volta lake who are predominantly Ewes. This suggests that low birth weight incidence in Ghana is more of an ethnic problem with some cultural undertones and parity as a main contributing factor than any other factor.

Conclusion: The geostatistical method adopted has been able to identify a more localized potential “hot spots” for low birth weight incidence that may not be evident using other non geostatistical methods. The results further show that low birth weight incidence in Ghana is more of an ethno-cultural problem with parity as a driving factor.

Surfaces are the primary place of contact a biomaterial and its host organism. Surface treatment or coating provides a means to overcome the problem which appeared after knee replacement surgery. There are two main problems; the stress shielding and subsequent bone remodeling causes bone resorption around the implant especially at the proximal part of the knee under the tibia tray. The other problem is stem tip pain. Therefore, the aim of this investigation is to find a new design of coating material of a cementless total knee replacement using functionally graded material (FGM). The objective of this research is to find the optimal material compositions, as well as the optimal gradation direction. It is found that using both vertical and horizontal FGM coating increased the von Mises stress at the proximal part of the tibial cancellous bone. Von Mises stress in cancellous epiphyseal bone is increased by 77% using vertical and horizontal FGM coating compared to hidroxyapatite HAP coating. It is found that this new coating design will improve the performance of a cementless tibia tray and will increase the life of the knee prosthesis.
