Kafeelah A. Yusuf, Surukite Oluwole, Ibrahim O. Abdusalam, Gbenga R. Adewusi

Abstract:-
This study investigated the distribution of SO2, NO2, PM10, CO, H2S, CH4 and noise in ambient air of Tin-Can port industrial estate Apapa, Lagos, Nigeria. Measurement was carried out at seven selected sampling sites in the months of October and November 2011. As a general finding, the selected air pollutant concentrations for SO2 and NO2 exceeded the USEPA national ambient air quality standards indicating traffic emissions and industrial sources. A statistical analysis using principal component analysis revealed that PC1 had high contributions from SO2, CO, H2S, Noise and moderate contribution from PM10(38.92 %) and was strongly associated with fossil fuel combustion, industrial sources and some non-road diesel equipment releasing sulphur dioxide into the air......

Ofdm Detection on Umts Utra-Fdd up-Link and Implementation of the Modulator/ Demodulator by Ifft/ Fft Algorithms
Ngom Agnès, Ouya Samuel, Farssi Sidi Mohamed, Ouess Mohamed El – Amine, Ndiaye Abdourahmane

Abstract:- In [1], we had applied OFDM modulation on UMTS UTRA-FDD up-link for multiplexing the physical data channels of a same mobile. We had given the expression of the OFDM signal emitted by a mobile having to send simultaneously K data symbols by channel for a total of N channels. In this paper, because the OFDM symbols was formed by chip time in [1], we process then the demodulation by chip time of the OFDM signal in [1] after its crossing of a perfect (without noise) frequency.........

Geophysical Investigation of Groundwater Potential in Ahmadu Bello University (Abu) Farm Area
Baba Adama Oleka, Benson Shadrach Jatau, Fadele S.I.

Abstract:- Hydrogeophysical investigation was carried out in Ahmadu Bello University Farm Area. The results obtain from the field were converted to response curves; depth of penetration of current to layers, resistivities, thicknesses, and groundwater potential were deduced. Water potential in the area shows three unit of water system at various depths (10 meter. 42 meter, and 82 meter). The apparent resistivity values ranges from as low as 29 ohm meter to as high as 25,027 ohm meter...........

Image Compression Techniques: A Survey
Athira B. Kaimal, S. Manimurugan, C.S.C .Devadass

Abstract:- The increasing attractiveness and trust on digital photography has given rise to its use for visual communication. It requires storage of large quantities of data. Due to limited bandwidth and storage capacity, images must be compressed before storing and transmitting. Many techniques are available for compressing the images. But in some cases these techniques will reduce the quality and originality of image. Some traces like blocking artifacts, transformation fingerprints etc are also introduced in to the reconstructed image as a result of compression. It mainly affect the medical imaging by reducing the fidelity and there by introducing diagnostic errors. Many hybrid techniques are also developed to overcome these problems. This paper addresses various compression techniques as it is applicable to various fields of image processing.
Keywords:-
Compression, Image compression, lossy compression, lossless compression, encoding, decoding.

On The Efficacy of Activated Carbon Derived From Bamboo in the Adsorption of Water Contaminants
Ijaola, O.O; Ogedengbe, K; Sangodoyin, A.Y.

Abstract:- A comparison of adsorption efficiency of the three Granular Activated Carbon (GAC) produced from waste Nigerian Bamboo at different level of activation in a fixed adsorption bed is reported. Bamboo carbonization was done at temperature range of 200-4000c and chemically activated at 4000c with chloride salt at percentage range of 0-20%. The 0, 10 and 20% level activation were selected for water treatment and comparison, based on surface pore area and........

Reduction of audio acoustic in Audio-visual transceiving with single port
Ujwal Pande, Shanti Swamy, K.N.Pande

Abstract:- In our day to day life we come across various challenges in communication. The communication is supposed to be complete only when an audio visualization is available, this can be achieved with audio visual communication. For audio visual communication a costly video-conferencing option is available for a small scale enterprise this cost is not affordable for internal communication. This paper deals with techno-economic remedy for mentioned problem by using single wireless transceiving port. When transceiving process is carried out an audio-acoustic effect hampers the communication quality........

Effects of addition of BaTiO3 Nano particles on the conductivity of PVdF/PMMA based polymer blend electrolytes
M. Ramesh Prabhu, S. Rajendra

Abstract:- Composite polymer electrolyte (CPE) membranes, comprising poly (vinylidene fluoride) (PVdF)/poly (methyl methacrylate) (PMMA), BaTiO3 as ceramic filler and LiBF4 as the lithium salt were prepared using a solution casting technique. The prepared membranes were subjected to XRD, FT-IR, impedance spectroscopy and thermal stability studies. The incorporation of nanofiller greatly enhanced the ionic conductivity and the thermal stability of the composite polymer electrolyte. Polymer blend electrolyte with 15 wt% of BaTiO3 ceramic powder exhibited higher ionic conductivity (1.335 x 10-3 S/cm) compared to the other ratios.

Fingerprint-Iris Fusion Based Multimodal Biometric System Using Single Hamming Distance Matcher
Ujwalla Gawande, Anushree Sapre, Apurva Jain, Sanchita Bhriegu, Shruti Sharma

Abstract:- In the real world applications, unimodal biometric systems often face limitations because of sensitivity to noise, intra class invariability,data quality, and other factors. Improving the performance of individual matchers in the aforementioned situation may not be effective. Multi biometric systems are used to overcome this problem by providing multiple pieces of evidence of the same identity. This system provides effective fusion scheme that combines information provided by the multiple domain experts based on score-level fusion method, thereby increasing the efficiency which is not possible in unimodal system.In this paper, we have proposedthe development of a fingerprint and iris fusion system which utilizes a single Hamming Distance based matcher to provide higher accuracy than the individual unimodal system.
Keywords:-Multimodal biometrics, fingerprint recognition, minutiae, iris recognition, hamming distance.
