The interaction of H2 and H2S with tungsten, and of H2S with hydrogen-covered tungsten, has bean investigated in the field emission microscope. A number of chemisorbed states with varying heats of adsorption have been identified throughout H2 adsorption at a pressure of 10-5Nm-2 and 78K on tungsten. When H2S was adsorbed at 295K and gas pressure of 10-5Nm-2 on clean tungsten surface a preferential interaction occurred along the (111) zones. An increase in the average work function of 0.3V has been found for the process. Desorption of hydrogen, resulting from H2S adsorption, began at 1270K. Migration of the remaining sulphur began at 1400K while desorption occurred above 1500K and was complete at 1870K. Activation energies for the desorpt

Due to the increased of information existing on the World Wide Web (WWW), the subject of how to extract new and useful knowledge from the log file has gained big interest among researchers in data mining and knowledge discovery topics.
Web miming, which is a subset of data mining divided into three particular ways, web content mining, web structure mining, web usage mining. This paper is interested in server log file, which is belonging to the third category (web usage mining). This file will be analyzed according to the suggested algorithm to extract the behavior of the user. Knowing the behavior is coming from knowing the complete path which is taken from the specific user.
Extracting these types of knowledge required many of KDD
Pure Poly [Allylamine-Co-Butadiene] having high molecular weight was prepared for the first time from the reduction of the Poly [Acrylonitrile-Co-Butadiene] using Lithium Aluminium hydride. Softening point of the prepared polymer was (201-207)C, conversion percent was 88%, with intrinsic viscosity of the new polymer in benzene as a solvent was 1.56.
Then the new polymer was allowed to react with six acid anhydrides, (Maleic, Phthalic, Succinic, Glutaric, 1,8-Naphthalic and cis 1,2,3,4-tetrahydrophthalic) to produce six novel pendant polymers which contain the acids reffered above in its recurrent units.

A principal problem of any internet user is the increasing number of spam, which became a great problem today. Therefore, spam filtering has become a research fo-cus that attracts the attention of several security researchers and practitioners. Spam filtering can be viewed as a two-class classification problem. To this end, this paper proposes a spam filtering approach based on Possibilistic c-Means (PCM) algorithm and weighted distance coined as (WFCM) that can efficiently distinguish between spam and legitimate email messages. The objective of the formulated fuzzy problem is to construct two fuzzy clusters: spam and email clusters. The weight assignment is set by information gain algorithm.

The motivation we address in this paper is to find out a generic method used to
segment and classify different types of conceptual images. A novel median based
method was proposed as primary stage for image segmentation, in which the image is
partitioned into fixed sized quadrants called kernels. The size of kernels in a specific
image is determined according to the spectral uniformity measurements. Later, Ant
Colony Optimization (ACO) is used to find out the optimal number of classes may exist
in the image, and then classify the image in terms of the determined classes. Different
types of images with different semantic concepts were used to test the proposed
classification method. The results obta

... Show MoreThe presence of the "calcite eyes" is related to an internal physiological reason rather than genetically reason or parasite inhabitation. The individual of this family tries to create open spaces in the areas of its body intensively crowded by the main partition or its branches to avoid oxygen scarcity (dysoxic condition). This mechanism keeps the living matter in touch each to the other as well as continuity of the animal life. After death and burial, these created spaces are filled with pure calcite, as it is the case in the chamber passage. This phenomenon took place in both megalospheric and microspheric generations.

The computer vision branch of the artificial intelligence field is concerned with
developing algorithms for analyzing image content. Data may be compressed by
reducing the redundancy in the original data, but this makes the data have more
errors. In this paper image compression based on a new method that has been
created for image compression which is called Five Modulus Method (FMM). The
new method consists of converting each pixel value in an (4x4, 8×8,16x16) block
into a multiple of 5 for each of the R, G and B arrays. After that, the new values
could be divided by 5 to get new values which are 6-bit length for each pixel and it
is less in storage space than the original value which is 8-bits.
