For decades, metal corrugated sheets have usually been manufactured using conventional roll-forming machines with lower and upper rollers or a die and a press as the main shaping elements. However, these machines and their related processes present economic disadvantages because of additional expenses required to improve and manage forming tools. To overcome these drawbacks, reconfigurable machines, such as dedicated and flexible manufacturing systems, were used as alternatives; they possess high flexibility for accomplishing forming processes. Reconfigurable machines are designed around a particular family of manufactured outcomes, allowing for high system flexibility. In light of the latest developments in reconfigurable machine design

Temperatures are important factors that have an impact directly and indirectly on
the human, so the attention to this aspect certainly will be in the interest of human
life. It is no secret to anyone increased warming and cause concern in the scientific
authorities. On this basis, interested search to produce digital map and classified
chromatically for the temperature distribution and by taking advantage of the band 6
of the satellite Landsat ETM+ and TM, also introduced in the calculations standards

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

Change detection is one of the most widely used processing techniques in remote
sensing. It is a process of identifying differences in the state of a geographic feature
or phenomenon by monitoring at different times. In order to detect the changes in a
phenomenon, the function Water Index (WI) is used to identify changes in water
content of the marsh during different periods of time. Landsat satellite data is used
of sensors MSS for the years 1974 &1992 and sensors TM 1984 and ETM sensors
for the years 2003, 2006, 2009 By using Arc GIS software, the results are converted
to thematic maps which represent water index coefficient through multiple years, as
well as the use of Erase tool in the tool

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"

Analyzing Google map to find optimal path routing is an important and advanced
strategy in geographic information system (GIS), it provides strong decision support
for the users in service area.
Optimal path routing system built to allows the users, businesses, and militaries to
find the optimal path (shortest and fastest path) between any two points (locations)
on a road networks (edges) of Google map image.

A new simple and sensitive spectrophotometric method has been developed for the determination of Bromhexine Hydrochloride in pure form and pharmaceutical preparations. The method is based on the diazotization reaction of Bromhexine Hydrochloride with sodium nitrite in hydrochloric acid medium to form diazonium salt, which is coupled with chromotropic acid to form a red water-soluble azo dye, that has a maximum absorption at λmax = 507 nm. Beer's law is obeyed over the concentration range (2-60 μg.ml-1) with RSD less than 2.050% and molar absorptivity of 1.569x104 l.mol-1.cm-1 and Sandell sensitivity of 0.0262 μg.cm-2. The method was applied successfully for the determination of Bromhexine Hydrochloride in pharmaceutical preparations.<

Edges are significant local changes of intensity in an image. In this paper, an
elimination rule which based on triangular inequality elimination (TIE) has been
adopted to perform the edge detection procedures. A new method has been included
the combining between an elimination rule which based on triangular inequality
elimination (TIE) and the differentiation operator by using the filters mask in one
dimension. The introduced algorithm has been produced a good image quality by
comparison with that which may be obtained by using the differentiation operator of
sharpening an image. The proposed algorithm has been proved it is good for finding
the edge in an image data.
