Since there are many types of mutations one common problem lies in selecting the appropriate type. The decision then becomes more difficult and needs more trial and error to find the best mutation to be used. This paper investigates the use of more than one mutation operator to enhance the performance of genetic algorithms. New mutation operators are proposed, in addition to two election strategies for the mutation operators. One is based on selecting the best mutation operator and the other randomly selects any operator. Several experiments were conducted on the Travelling Salesman Problem (TSP) to evaluate the proposed methods. These were compared to the well-known exchange mutation and rearrangement mutation. The results show the importance of some of the proposed methods, in addition to the significant enhancement of the genetic algorithms' performance, particularly when using more than one mutation operator.

This partition determines the number of elements for each order. The aim of this paper is to find the order classes of 2-generator p-groups of class 2. The results obtained here are supported by Groups, Algorithm and Programming (GAP).

The core of this classifier depends mainly on measuring the distance or similarity between the tested examples and the training examples. This raises a major question about which distance measures to be used for the KNN classifier among a large number of distance and similarity measures available? This review attempts to answer this question through evaluating the performance (measured by accuracy, precision and recall) of the KNN using a large number of distance measures, tested on a number of real-world datasets, with and without adding different levels of noise. The experimental results show that the performance of KNN classifier depends significantly on the distance used, and the results showed large gaps between the performances of different distances. We found that a recently proposed non-convex distance performed the best when applied on most datasets comparing to the other tested distances. In addition, the performance of the KNN with this top performing distance degraded only about 20% while the noise level reaches 90%, this is true for most of the distances used as well. This means that the KNN classifier using any of the top 10 distances tolerate noise to a certain degree. Moreover, the results show that some distances are less affected by the added noise comparing to other distances.

Malaysia is the world’s largest producer of palm oil in the industry. Since palm oil clinker is abundant, lots of attempt have been made to investigate the possible use of this material, especially in the field of construction more so, as concrete is one of the most versatile construction materials. This agricultural waste, being referred to as Palm Oil Clinker Incinerated By-products (OPIB), can totally replace the stone aggregate in concrete mixtures. In this research, the focus is on the strength development of OPIB concrete. Tests have been conducted to investigate the effect of using OPIB aggregate, on the engineering properties of concrete in order to determine the optimum mix proportion of lightweight concrete, using different OPIB of aggregate size. In the tests, the aggregate is graded and...

Police reports and questionnaires were used in the study; the questionnaires were processed by the drivers. The results indicated that there were some points in the questionnaire which agree with the police reporting where the other didn’t agree with it, in comparing the results of self-reporting records with those of the police some points were not.

Three sieve sizes of crumb rubbers were used in asphalt mixture No. 4, No. 8 and No. 50, with five percent of asphalt cements (4, 4.5, 5, 5.5 and 6%) by weight and four percent of crumb rubbers (10, 20, 30 and 40%) by weight used as an aggregate for preparing asphalt mixture specimens. The Hot Mix Asphalt (HMA) Marshal test method for asphalt mixture specimens was used; 72 specimens were prepared for evaluation of Marshall Properties (flow, Stability, bulk density, air void percentage and void in mineral aggregate). Previous studies showed that the crumb rubber has further effects on the performance of asphalt mixture by increasing its Marshall flow, stability, air voids and decreasing the bulk density. It is concluded that the crumb rubber as a fine aggregate improves the stability and flow with respect to a crumb rubber as a coarse aggregate.

Pozzolans of Jabl Onyzh have been described as the major supply from Jordan. It is often used in the place of a conservative aggregate in frivolous concrete. A practical examination was carried out on the resistance of Pozzolana Lightweight Concrete (PLWC) with diverse ratios (35 and 50%) of pozzolana from the whole size of admixture order to ascertain its impact. In this study, a design mix was used with several A mix design was determined through various experimental mixtures to make certain that the pozzolanas lightweight concrete will be able to attain the needed fundamental performance. A self-fabricated was used to simulate a low-velocity projectile effect on the slab specimens was aroused with the use of a self-invented drop-weight impact test rig. Twofold factors were examined to determine the impact resistance on slab (300×300 mm) with diverse viscosity (20, 25 and 30 mm) support, with pozzolana content and concrete thickness. The impact resistance of concrete decreases with the addition of pozzolana but progresses with slab thickness. However, the influence is more prominent for the final crack resistance than for the first crack resistance. When slab thicknesses were compared with each other, the outcome was that 25 cm has a general superior performance in lightweight concrete for impact resistance.

This paper investigates for the first time a new way to identify persons, particularly (terrorists) from their victory sign. We have created a new database in this regard using a mobile phone camera, imaging the victory signs of 50 different persons over two sessions. Simple measurements for the fingers, in addition to the Hu Moments for the areas of the fingers were used to extract the geometric features of the shown part of the hand shown after segmentation. The experimental results using the KNN classifier were encouraging for most of the recorded persons; with about 40% to 93% total identification accuracy, depending on the features, distance metric and K used.

The use of Bentonite as filler materials in self-compacting concrete can add many benefits that are directly related to the durability of various cementitious materials, besides the fact that it is possible to reduce the quantities of cement and optimize the percentage in the composite. The performance of the model can be judged by the correlation coefficient (R2), Mean Absolute Error (MAE) and root Mean Square Error (MSE) have been adopted as the comparative measures against the experimental results obtained from the mixtures and found the best percentage of Bentonite in SCC.

It is played by two teams, each consisting of at least one player. In addition to presenting the game and its rules, the authors develop three versions of the game: human versus human, human versus computer, and computer versus computer. The authors employ a Genetic Algorithm (GA) to help the computer to choose the ‘best' move to play. The computer game is designed allowing two degrees of difficulty: Beginners and Advanced. The results of several experiments show the strategic properties of this game, the strength of the proposed method by making the computer play the game intelligently, and the potential of generalizing their approach to other similar games.

In recent years, occasional attestations of game boards have been found in rock surfaces corresponding with geographical locations at the outer borders of the Ottoman Empire, such as Sudan and Oman. In those locations, the game boards were differentiated from Roman gaming practices.
This survey of the archaeological region of Petra in Jordan reveals an unusually large number of ṭāb playing boards carved in rock surfaces. The study presents the implications of these finds for our understanding of the game, as well as the importance of this game for the history of the region.
