This study was carried out to estimate the effect of shaliness on water saturation from TN field of Niger Delta. The conventional Archie and the Shaly-sand water saturation models was used in the evaluation of wells. Two sand bodies (Sand 01 and 02) were mapped with thicknesses range from 76.8ft to 119.3ft across the three wells for Sand 01 and 187.5 to 339.9ft across wells TN_1 and TN_4 for Sand 02. The cross plot of the effective porosity (φe) versus volume of shale (Vsh) show a decrease in the effective porosity with an increase in shale volume. This reveals a laminated shale pattern across the reservoir sands. The estimations from the conventional method and the Shaly-sand models of Simandoux and Indonesia show a clear disparity due

The number and quality of commercially available multispectral sensors and the
data they provide are continually improving, but there is always compromise
between achieving high spatial resolution, necessary for those applications that
require high degree of detail, and high spectral resolution when a better feature
discrimination level is needed. However, there are some situations that
simultaneously require high spatial and spectral resolutions in a single image. The
techniques of data fusion, or data merging, provide an alternative to that constraint,
being used to combine low-resolution multispectral satellite imagery with higher
resolution panchromatic or radar imagery, improving their visual

In this paper, a proposed video tracking system is introduced. The proposed
system consists of two parts: motion estimation and tracking. Motion estimation is
carried out by computing the difference between two successive images. The
difference is dark image contains small relatively brightness at the region of
existence the moving object. The average location of the moving object in the
difference image is the target location, the tracking aims to make the head of camera
facing the target location. Such that, the relation between the head of the camera and
the target location relative to camera location is modeled to computes the deflection
in the head. The tracking part depends on the head deflec

The field of mathematical morphology contributes a wide range of operators to image processing, all based around a few simple mathematical concepts from set theory. The two most basic operations in mathematical morphology are erosion and dilation, both of these operators take two pieces of data as input; an image to be eroded or dilated, and a structuring element. Opening and closing are two important operators from mathematical morphology; they are both derived from the fundamental operations of erosion and dilation. The primary application of mathematical morphology in this work occurs in binary images throw applying erosion and dilation operations to extract boundary edges, and then basic morphology operations are adopted to grey leve

The iris of human eye is one of the most useful traits for biometric recognition.
This paper presents an iris recognition system based on semantic indexing. The
proposed system uses the concepts of latent semantic indexing (LSI) for iris
recognition. One technique of LSI is the singular value decomposition (SVD). The
SVD is an information retrieval uses numerical decomposition methods to compute
one characteristic value (i.e. SVD) for each iris image to be used as a recognition
feature. The proposed system consists of two phases: the training and recognition.
The training phase is responsible on storing the iris models in the database, while the
task of recognition phase is to compute the similarit

Most of the Arabic language vocabulary is built from the roots derivation. These roots are words composed of three to five consonants letters. Any performance in Arabic language for the purpose of information retrieval needs to deal with the language morphological and structural changes first (which is called the stemming process) then a statistical method for extracting information is implemented. This approach presents a method for categorizing the Classical Arabic Poetry (CAP) into its categorizations: Ghazal, Medeh, Wasef, Hijaa',..etc. by combining the algorithm of a light stemmer (which identify sets of prefixes and suffixes in an Arabic word in order to reach to the word root after removing the suffixes and prefixes) with "N-gram"
