Extracting knowledge through the machine learning techniques in general lacks in its predictions the level of perfection with minimal error or accuracy. Recently, researchers have been enjoying the fruits of Rough Set Theory (RST) to uncover the hidden patterns with its simplicity and expressive power. In RST mainly the issue of attribute reduction is tackled through the notion of ‘reducts’ using lower and upper approximations of rough sets based on a given information table with conditional and decision attributes. Hence, while researchers go for dimension reduction they propose many methods among which RST approach shown to be simple and efficient for text mining tasks. The area of text mining has focused on patterns based on text files or corpus, initially preprocessed to identify and remove irrelevant and replicated words without inducing any information loss for the classifying models later generated and tested. In this current work, this hypothesis are taken as core and tested on feedbacks for e-learning courses using RST’s attribution reduction and generating distinct models of n-grams and finally the results are presented for selecting final efficient model.

Internet is a network of interconnected systems which works collaboratively and services the users without any disruption. But for achieving the same in real time, needs the new prominent technology cloud computing. The massive attractive features and simple pay-as-you-go model of cloud makes it reachable to all the users Denial-of-Service (DoS) plays a crucial role in making the services inaccessible to its intended users. The traditional DoS can no longer be successful in the cloud scenario as it poses the auto scaling feature. Still, the DoS can consume the bandwidth of the cloud customers as they need to pay for their complete usage. In spite of the huge number of recovery measures available in cloud, DoS becoming harder every day in terms of attack volume and severity. Hence complete mitigation against DoS attack is the expected solution which needs to be proved in today’s digital world. Moving Target Defence (MTD) is one such prominent emerging solution which aims to avoid the DDoS attacks in the cloud environment. The challenge of MTD is to change the attack surface periodically such that the attackers will be facing difficulty in even the attack attempts. This paper aims to provide solution for avoiding DoS attack by adopting MTD algorithm for making the web servers redundant in the cloud environment. Experimental simulations prove the effectiveness of MTD in the public cloud environment.

Topology of the of interconnection network is one of the most important considerations in the design of parallel systems as it is the backbone network over which the different components of the computer communicate with each other. The properties of the topology such as connectivity, reliability, cost, fault tolerance, diameter and bisection width determine the flawless-less data transmission between the source and the sink nodes. In this paper, we propose a new hybrid interconnection network topology called TOR-CUBE (TC) which is a product of two classical popular interconnection topologies namely hypercube and torus. Further, we show the construction and characteristics of the proposed interconnection topology. We also presented some basic important properties and formulated two routing algorithms for TC. Our results show that the proposed interconnection topology has high connectivity, lesser diameter, low cost, fault tolerant, scalable and low average distance. The different reliability measures of TC are computed and found to be better as compared with its counterpart topologies and the parent topologies.

The aim of operation reservoir during flood is to prevent overflow that endangers the dams. It is also to prevent flooding in the downstream of the dam, which leads to loss of life and property. This aim can be achieved with optimal reservoir management which is influenced by the reservoir’s condition during flooding such as: rain, reservoir storage, inflow, water level, and discharge of reservoir water released to the downstream. The successfully of the reservoir management depends on the accuracy of the estimated a). water level (due to the inflow of the reservoir) and b). outflow from the reservoir. One of the models which can be used to predict the water level and reservoir water released during flooding is the Artificial Neural Network (ANN). ANN can simulates flood events that are similar in fact to the previous occurence In this study a backpropagation ANN model was applied to the Wonogiri Reservoir in Central Java, Indonesia. The optimal ANN architecture produced in this study are the Input Pattern of 5-3-4 (which has a rain input recorded 1 – 5 hours earlier, a water level input recorded 1 – 3 hours earlier and a release input recorded 1 – 4 hours earlier). 27 pieces hidden layer, total epoch which is 200 and the learning rate of 0.01. The output is predicting the water level, the Outflow and Gate Opening of Reservoir. The current flood data was applied to the above model and it was concluded that the network can follow the flood management pattern adequately. In addition, the network is extra flexible with a lower flood discharge rate; and has the final elevation of the reservoir slightly lower than the normal operation.

The Nigerian Geodetic Reference Frame is defined by a number of Continuously Operating Reference Stations (CORS) that constitute the Nigerian GNSS Network (NIGNET). NIGNET is essential for planning and national development with the main goal of ensuring consistency in the geodetic framework both nationally and internationally. Currently, the strength of the network in terms of data reliability has not been adequately studied due to the fact that research into CORS in Nigeria is just evolving, which constitutes a limitation in its applications. Therefore, the aim of this research is to explore the reliability of the 3-dimensional coordinates of NIGNET to inform usability and adequacy for both scientific and practical applications. In particular, this study examines if the 3-dimensional coordinates of NIGNET are equally reliable in terms of positional accuracy. Accordingly, this study utilised GNSS data collected over a period of six years (2011 – 2016) from the network to compute the daily geocentric coordinates of the stations. Exploratory and statistical data analysis techniques were used to understand the magnitude of the errors and the accuracy level in the 3-dimensional coordinates. For this purpose, accuracy metrics such as standard deviation (𝜎), standard error (𝑆𝐸) and root mean square error (RMSE) were computed. While One-way ANOVA was conducted to explore the coordinate differences. The results obtained showed that SE and RMSE ranged from 13.00 − 56.50𝑚𝑚 and 14.38 − 73.16𝑚𝑚 respectively, which signifies high accuracy. Overall, while 88% of the network showed a high level of positional accuracy, the reliability has been compromised due to excessive gaps in the data archiving. Therefore, due attention must be given to NIGNET to achieve its purpose in the provision of accurate information for various geospatial applications. Also, any efforts directed at understanding the practical implications of NIGNET must be well-embraced for the realization of its set objectives.

Markets are economic institutions serving as social entities. Diverse people based on ethnic groups, racial backgrounds and cultural traits are linked by a market. Socio-cultural, religious and political activities equally take place in the markets. This study was carried out in Okitipupa the regional headquarter of Ikale people of Ondo State. The sample size of 120 was selected by the purposive sampling technique, taking cognizance that they were fully representative of the populations of the study area. The questionnaires retrieved, were coded and analysed using SPSS (Statistical Package for Social Sciences) Version 16 computer programs and the Excel spreadsheet software. The findings of the study reveal that infrastructure such as road, water, electricity, and waste management facilities were in a deplorable state. This in effect created a problem for market women and a discomfort to patrons of the market. It is recommended that the community should embark on self-help development of the market, create market management committee, seek for the intervention from the government and provide sustainable redevelopment programs for quick improvement of the market.
Investigating the Reaction and Transport Controlled Mechanism for the Sorption of Cr(III) and Mn(II) Ions onto Acid Activated Shale using Non-Linear Error Functions

Published: August 2019

Time dependent adsorption study on the sorption of Cr(III) and Mn(II) ions onto acid activated shale was conducted using batch adsorption techniques to investigate the effect of initial metal ion concentration on the process of adsorption. Experimental data obtained were fitted into different kinetic models to analyze the mechanism of adsorption in terms of reaction controlled and transport controlled mechanism. Some of the selected kinetic models include; Pseudo-first order, Pseudo-second order, Elovich, Film diffusion, Parabolic diffusion and Intra-particle diffusion model. From the result, it was observed based on the linear coefficient of determination (r2) that the experimental data fitted well into the various kinetic model tested. Application of non-linear error function such as error sum of square (SSE), root mean square error (RMSE) and residual average (RA) revealed that the rate limiting step for the adsorption of Cr3+ and Mn2+ ions on acid activated shale was chemical attachment (chemisorption) and the reaction mechanism follows the Pseudo-second order kinetic model.

Farmers in the tropical environment face the acute problem of using mineral fertilizers due to their unsustainable attributes ranging from scarcity and high cost of the material to the adverse effects on tropical soil which resulted to soil acidity and pollution of underground water. This study evaluated the effects of rice-bran compost on the growth and yield of improved variety of soybean on an Alfisol, in Ibadan, Nigeria. The investigation involved a screen house experiment conducted at the Department of Agronomy, University of Ibadan. The experiment comprised five rates of compost (0, 2.5, 5.0, 7.5 and 10 t/ha) replicated four times with two pots per replicate in a Completely Randomized Design (CRD) using soybean (TGX 1740- 1F) variety with a total of 40 pots in all. The data collected were subjected to analysis of variance ANOVA and Duncan multiple range test was used to separate the means. The experimental results showed significant differences (p˂0.05) among the levels of compost on soybean; however, 10 t/ha gave the highest value on the number of leaves while 7.5 t/ha performed better in respect of plant height compared with the other treatments. Also, rice bran compost at 10 t/ha produced statistically highest root and grain yields followed closely by 7.5 t/ha. However, 10 t/ha of rice bran compost promoted shoot performance. Soybean yield increased with higher rates of rice-bran compost. Soybean growth and yield are improved with a compost of rice- bran and cattle dung up to 7.5 t/ha to supply 95 kg N, 169 kg P and 12 kg K.

Soil degradation due to water erosion among other causes has been a major problem in southeastern Nigeria, therefore a study was conducted to determine sediment yield, detachment, and runoff from soil under selected parent material in southeastern Nigeria. The objective was to characterize the selected soils in terms of their physical and chemical parameters, carry out rainfall simulation, and to establish some relationships that exist among studied parameters with selected soil properties. Soil samples were collected in three replicates from twenty locations, 5 location each from 4 geologic formations namely Asu River Group, Bende Ameki Group, Coastal Plain Sand and False bedded Sandstone at a depth of 0 – 20 cm using soil auger. Standard laboratory procedures were followed for samples for routine analyses while the rest was subjected to rainfall simulation at an intensity of 190 mm/hr for a period of 30 minutes under dry and wet conditions of the soils. Result showed that significant P<0.05) differences among studied parameters. Sediment yield under wet and dry states ranged from 0.56 - 3.95 kg m-2 hr-1 and from 0.80 - 4.97 kg m-2hr-1. The highest sediment yield under both conditions was recorded at Ishiagu, Bende, Obinze and Okigwe from ARG, BAG, CPS and FBS derived parent materials, respectively. Detachment under both conditions ranged from 0.04 - 0.13 kg m-2hr-1 and from 0.03 - 0.21 kg m-2 hr- . Similarly, runoff ranged from 79.80 - 125.30 mm and 28.00 – 106.90 mm under wet and dry states. Result also indicated a negative relationship between clay fraction and sediment yield (r= - 0.62) under dry and ( r= - 0.27) under wet condition. Conclusively, the study noted that rainfall has great impact on studied soils as higher values of sediment yield and detachment were noted mostly under dry than in wet conditions.
