In this paper we present a numerical technique for solving Kuramoto-Sivashinsky equation, based on spectral Fourier methods. This equation describes reaction diffusion problems, and the dynamics of viscous-fuid films flowing along walls. After we wrote the equation in Fourier space, we get a system. In this case, the exponential time differencing methods integrate the system very much more accurately than other methods since the exponential time differencing methods assume in their derivation that the solution varies slowly in time. When evaluating the coefficients of the exponential time differencing and the exponential time differencing Runge Kutta methods via the”Cauchy integral”. All computational work is done with Matlab package.

The main objective of this paper is to design a generalized architecture for polyphase code identification used in RADAR signal processing applications. The proposed VLSI architecture will identify the type of a given polyphase code, amount of phase change and number of phase changes. RADAR signal processing applications require a set of sequences with individually peaky autocorrelation and pair wise cross correlation. Obtaining such sequences is a combinatorial problem. This paper aims at implementation of an efficient VLSI system for the design of polyphase codes identification useful for RADAR applications. The VLSI system is implemented on the field programmable gate array as it provides the flexibility of reconfigurability and reprogrammability and it is a real time signal processing solution which identifies the polyphase codes. The simulation results and the FPGA implementation shows the successful code identification, amount of phase, number of phase changes for a given input sequence.

Recently, irregular sampling techniques have been proposed for the design of digital front-end of a radio receiver. This front-end consist in the interface between the analog front-end and the baseband processing. The advantage of these techniques is the simplification of the sampling frequency conversion and the channel selection. The objective of the proposed work is to study if a gain in power consumption is also obtained. In this paper, the major research is the digital-front-end power consumption by using random sampling. Firstly, we introduce the methods of random sampling JRS (Jitter random sampling) and ARS (Additive random sampling). Then we use these methods to generate the random clock, select the hardware as mixed platform with ADC and FPGA and implement different solutions. At last, we measure the power consumption of different solutions and make a comparison.

Availability of clean water is a serious problem, especially in developing countries like Nigeria, where conventional treatment methods are inappropriate due to high cost and low availability of chemical coagulants like alum. The paper presents the use of moringa seeds extract as alternative to alum in raw water treatment. Preliminary engineering properties such as jar test, speeds of flocculation; 98, 196 and 260rpm; detention and setting times were conducted to determine the integrity of moringa extract as a natural coagulant. The results shows that at the speed of 98rpm and settling time of 1 hour, 85 – 89% removal of solids was achieved, while 41 – 59%, 63 – 80% removal of solids were possible at 260rpm and 196rpm respectively. Similarly, after 2 hours of settling time, 93 – 96%, 64 – 75%, 65 – 80% removal of solids were obtained at 98rpm, 260rpm and 196rpm respectively. The treatment suggests optimum performance at low and medium speeds better than maximum speed of flocculation. It is suggested that further investigation be carried out on particle sizes of moringa oleifera seeds powder.

This study investigated pollutants emissions from filling stations and their impact on the air quality. Gas monitors were employed to identify the different pollutants present in the ambient air of the study areas. The results showed that the most prominent pollutants present in the ambient air are the volatile organic compounds followed by methane, then carbon monoxide. Measurements were taken at the controls at distances between 20 to 200m.The pollutants concentration recorded at the study areas showed that the level of pollutants exceeded the FEPA air quality guidelines. There are few exceptions in pollutants like the particulate matter which was found to be at concentrations within the FEPA limits. Regression analysis of the pollutants at the controls showed that only the volatile organic compounds and methane are the only significant pollutants present in the ambient air primarily because of the presence of the filling stations. These two pollutants showed a strong negative correlation with distance from the study area. While the regression curve for the volatile organic compounds (VOCs) shows a nearly perfect curve with exponential functions as its regression equations, that of methane is linear. Specifically, both VOCs and methane have a correlation coefficient (R) that is above 0.9 for the study areas. Hence a conclusion was drawn from the findings that the primary pollutant to consider when building filling station are the VOCs and methane and that the minimum safe distance to site a filling station is a distance of 80m away from residential areas.

Deliberate or accidental burning of materials containing heavy metals such as electronic components may result in serious environmental pollution. Burning of these materials is common in open waste dumps and sometimes during fire disasters. This paper looked at the determination of heavy metal concentration in soil samples at burnt computer business centre (A case study of PTI, Effurun). Soil samples were collected from the site and another sample from unaffected area as control. The samples were analyzed for the presence of copper, zinc, cadmium, lead and mercury using GBC Scientific AAS GF 3000. The result of the analysis shows that the concentrations of the heavy metals at the site are much higher than the control sample. The mean concentration of copper is 0.284ppm which is more than 2400 % higher than the control sample’s concentration of 0.011 ppm, lead 2.749 ppm higher by 50 %, cadmium 0.058 ppm higher by 222 %, and zinc 1.626 ppm higher by 80 %. Though the concentrations of the heavy metals analyzed are much higher than that of the control sample, yet they are less than the maximum permissible limits by World Health Organization (WHO) for soil except cadmium in samples C and E (0.09 ppm each) which is higher than the WHO maximum permissible limits of 0.06 ppm. Based on the results obtained, it can be concluded that there is an increase in concentration of heavy metals in the burnt computer business centre.

This study ascertained the extent of pollution of the water body of river Benue at the reach of Makurdi. Trend analysis gives an insight to the possible outcome over a period of time in data processing. In this study, available data for twelve points ranging from 1 – 12m distance, and some laboratory analysis were used to estimate the trend of Escherichia Coli (E.coli), Biochemical oxygen Demand (BOD) and chemical oxygen demand (COD) in river Benue at the reach of Makurdi, Benue State. The concentration of E.coli ranged from 584.7 cfu/100ml to 1067.1 cfu/100ml, BOD values ranged from 727.3 mg/l to 870.4mg/l and COD values ranged from 1454.7mg/l to 1758.6mg/l. The values increased with distance with the highest E-coli, BOD and COD at the 12m distance. Three regression models for trend projection were developed. The trend shows that, the water quality of river Benue is not pleasant. Some recommendations are made and if adopted will help to improve the quality of the water for consumption and other recreational purposes.

New measurement method for soil surface profile has been described in this study. This method includes new designed soil profile meter, digital imaging equipment and image tracking & analysis software. Using such modified soil profile meter can help to observe and measure changes occur in irrigation channels, small ditches and to quantify changes at specific cross sections within soil furrows. By using image processing and tracking system we can trace marked points in fixed level of meter pins, these points have vertical displacements and vary according to existing profiles and cross-sectional shape in different locations, which give us ability to record presented form of different profiles. The modified profile meter used to measure and track changes in different profiles; two types of ditches and two types of furrow. The recorded profiles heights for different locations gave us perspicuous knowledge about the geometry of furrows and ditches shapes before and after seasonal irrigation process. The differences in measurements for same locations and sites have been noted. Designed soil profile meter successfully demonstrated changes in profiles pattern due to surface irrigation erosion in term of height variations, for shallow and wide ditches, the differences in measured heights by soil profile meter after and before the irrigation generally ranged from 0 to 11 mm, while in deep ditches, differences in heights ranged from 0 to 44 mm. With ridge profiles, soil profile meter tracked variation in measured heights from 0 to 13.88 %, also, high percentage of variation obtained by studying flat top bed furrow changes, the largest percentage was 17.1 % at beginning of the furrow line. This clarifies the ability to track and record erosion effect in different furrows and ditches by using soil profile meter as a part of used image processing and tracking system.
