ACO: Decisive Artificial Ants
Hassan Soltan
1
Abstract
The Ant Colony Optimization was inspired by the foraging behavior of real ant colonies. The main determinants of an ant algorithm are the way of pheromone update and the transition probability of an ant‘s travel from a position to another. This paper proposes adopting the decision systems to develop the transition probability function and make other frequent decisions such as switching between ways of pheromone update. This increases the possibility of deriving and improving a variety of ant algorithms. The original transition probability function is investigated and other three formulas have been developed as general frameworks for the problems of multiple objective. The Analytic Hierarchy Process is followed as a base for this contribution; thus, unlimited number of factors can be involved. Furthermore, paradoxical views are discussed to synthesize different types of artificial stigmergy to energize the artificial ants with more robust interaction.

ABSTRACTFor an ordered set P and for a linear extension L of P, Let s (P,L) stand for the number ofordered pairs (x, y) of elements of P such that y is an immediate successor of x in L but y is noteven above x in P. Put s(P) = min { s (P,L) : L linear extension of P}, the jump number of P.Call an ordered set P is jump-critical if s (P-{x}) < s (P) for any xP. We introduce some theoryabout the jump-critical ordered sets with jump number four. Especially, we introduce a completelist of the jump-critical ordered sets with jump number four ( it has four maximal elements).Finally, we prove that a k-critical ordered set is a k-tower ( its width is 2, k >1).KEYWORDS: Jump number, jump-critical ordered sets.

E. Abou El Dahab
1
AbstractThe basic concepts of generalized Hamiltonian ( Birkhoffian ) mechanics are derived usingGemotric Algebra. Both Generalized Poisson bracket (GPB) and Generalized Lagrangebracket (GLB) are introduced. Similarly Generalized plus Poisson bracket (GPPB) andGeneralized plus Lagrange bracket (GPLB) are derived which seems different from the formsby other authors. Differential constrains are derived, one of which resembles that ofelectromagnetic field strength.

Abstract:This paper proposed the application of the fuzzy evaluation model using fuzzy sets andapproximate reasoning. The objective of the study is to evaluate the weapon system in asubjective environment. The proposed method based on fuzzy sets has initiated the idea ofmembership set score value evaluation of each criterion alternative. This enables the inclusionof requirements which are incomplete and imprecise. The approximate reasoning of themethod allows the decision maker to make the best choice in accordance to human thinkingand reasoning processes. The proposed model is based on fuzzy multi-criteria decisionmakingthat consists of fuzzy rules. The use of fuzzy rules, which are extracted directly frominput data in making evaluation, contributes to a better decision in selecting the best optionand less dependency on the domain of experts. Finally, we constructed a practical examplefor evaluating attack helicopters to demonstrate the proposed method. From these results, theproposed method shows outstanding performance in comparing with Cheng et al.’s methodwith 100% accuracy in ranking three attack helicopter alternatives, S1 (MI-28), S2 (AH-64,and S3 (AH-1w). Again the subjective evaluation method showed the advantages of simplerrules properties in NR , Max_L and Min_L. This research work has achieved its objective andproduced good evaluation results. This portrays its major advantages in making decisions innew cases, where there is limited or an absence of specific knowledge.

Abstract.In this paper, with the help of the Lucas Riccati method and a linear variable separationmethod, new variable separation solutions with arbitrary functions are derived for a (2+1)-dimensional modified dispersive water-wave system. Next, we give a positive answer for thefollowing question: Are there any localized excitations derived by the use of anotherfunctions? For this purpose, some attention will be paid to dromion, peakon, dromion lattice,multi dromion-solitoff excitations, regular fractal dromions, lumps with self-similar structuresand chaotic dromions patterns based on the golden main and the symmetrical hyperbolic andtriangular Lucas functions.

AbstractWe consider non-linear singular perturbation problems of the form y (x ) p(y (x ))y (x ) q(x , y (x )) r (x ) , y (0) , y (1) with a boundary layer at one end point.The method is distinguished by the following fact: The original problem is reduced to anasymptotically equivalent first order initial value problem (IVP). Then, an initial-valuealgorithm is applied to solve this IVP. The algorithm is based on the locally exact integrationof a linearized problem on a non-uniform mesh. Two terms recurrence relation withcontrolled step size is obtained. Several problems are solved to demonstrate the applicabilityand efficiency of the algorithm. It is observed that the present method approximates the exactsolution very well.

Abstract:In this paper we describe a methodology that includes the complementary use of response surface methodology (RSM) and simulated annealing algorithms(SAA).In this methodology we use response surface methodology (RSM) through 12 experiments for 3 input (depth of cut- cutting speed and feed rate) with 3 levels for each to develop an approximating model for end-milling process. This approximating model is based on observed data from the process. Then we use simulated annealing algorithms to solve this model within the range of the factors (depth of cut- cutting speed and feed rate) to predict the optimal value of surface roughness and cutting condition.

Abstract
In a fuzzy environment, Decision Maker (DM) generally gives all objectives their vague targets. DM permits the objectives less than or equal to (or more than or equal to) aspiration levels by predetermining the respective tolerances. In this research, an approach to the case of the fuzzy multiple objectives linear programming problems with fuzzy goals in objective functions and constraints is described. This approach is associated with modifying the compromise model by reconstructing the membership functions by changing tolerances of the objectives using the principle of the interactive Attainable Reference Point Method to guarantee the optimization problem feasibility. To demonstrate the effectiveness of the optimization approach proposed here a numerical example is solved.

AbsractThis paper deals with the possibilistic linear programming problem with exponential distribution function which is converted to a usual mathematical programming problem based on maximizing the possibility measure, then the stochastic linear programming problem with multivariate normal distribution is treated using the probability maximization model. For such problems the stability set of the first kind is defined and characterized. The transformation between the possibilistic linear programming problem with exponential distribution function and the stochastic linear programming problem with multivariate normal distribution is discussed also. Finally, numerical examples is given to illustrate the idea developed in this paper.

AbstractThis paper presents an efficient evolutionary algorithm for solving multiobjectivetransportation problem MOTP. a new chromosome's structure was introduced, which isadopted as it is capable to representing all possible feasible solutions. Also, in order to keepthe feasibility of the chromosome, a criterion of the feasibility was designed. Based on thiscriterion the crossover and mutation were implemented and they can always generate feasiblechromosomes. To avoid an overwhelming number of solutions the algorithm maintains afinite-sized archive of non-dominated solutions, which gets iteratively updated in the presenceof new solutions based on the concept of Epsilon-dominance. Epsilon dominance processsaves the most representative solutions. Finally, we report numerical results in order toestablish the actual computational burden of the proposed algorithm and to assess itsperformances with respect to classical approaches for solving MOTP.

Abstract
The effect of Al–substitution on the physical, magnetic and electrical properties of Ni–Cu–Zn ferrite of chemical formula Ni0.4Cu0.2Zn0.4AlxFe2-xO4 (x = 0 to x = 0.15 with step = 0.025) which prepared by conventional ceramic method has been studied. X-ray patterns indicated the presence of a single spinel phase. The magnetization is measured using VSM at room temperature. The initial permeability is measured, on toroidal samples used as transformer cores, as a function of temperature at constant frequency of 10 KHz and Curie temperature is determined. It was found that Al–ion substitute improved the magnetization as well as the initial permeability. The dc resistivity is also increased with increasing Al – concentration. Such results are promising ones for the high frequency applications.

AbstractPlasma technology utilised in power engineering can be divided to: I. High temperature plasma technology. The development of experimental equipment for decomposing the toxic compounds that arise in the pyrolysis or combustion of PCB oils, plastics and other dangerous wastes, by subsequently raising the combustion temperature above the threshold for dissociation of toxic gas molecules. The design of experimental dissociation chamber plant, rated at 100 kg/hour of dangerous waste is presented. II. Low temperature plasma technology is one of the possibilities how to replace efficiently noble fuels (mazut or gas) used for the start-up and stabilization of power stations and utilization in the incineration plants. The output 320 kVA of plasma generator and temperature 6 000 oC for the boiler is sufficient. The operating costs of plasma ignition of coal powders are significantly lower than the start-up of boiler with mazut, and/or the start-up or stabilization with the use of gas. These conclusions have been fully confirmed and verified.

Abstract
Optical imaging systems are widely used in different applications include tracking for portable scanners; input pointing devices for laptop computers, cell phones, and cameras, fingerprint-identification scanners, optical navigation for target tracking, and in optical computer mouse. We presented an experimental work to measure and analyze the laser speckle pattern (LSP) produced from different optical sources (i.e. various color LEDs, 3 mW diode laser, and 10mW He-Ne laser) with different produced operating surfaces (Gabor hologram diffusers), and how they affects the performance of the optical imaging systems; speckle size and signal-to-noise ratio (signal is represented by the patches of the speckles that contain or carry information, and noise is represented by the whole remaining part of the selected image). The theoretical and experimental studies of the colorimetry (color correction is done in the color images captured by the optical imaging system to produce realistic color images which contains most of the information in the image by calculating the RGB components) for the used optical sources are investigated and introduced to present the relations between the signal-to-noise ratios with different diffusers for each light source. From the experimental results, we found that the speckle size ranged from 4.59 to 4.62 m, which are slightly different or approximately the same for all produced diffusers. But, the calculated value of signal-to-noise ratio takes different values ranged from 0.69 to 0.92 for different diffuser, which means that surface texture will affects the performance of optical sensor based on laser speckle pattern used for optical imaging system.

Abstract A complete characterization and comparison of thermal effect between two high power fiber coupled diode laser modules operating at wavelengths of 808 nm and 975 nm. For the diode laser to operate at certain wavelength, the internal construction and the used material inside the diode must be different. Both wavelengths have a wide use in the laser design such as pumping another active medium to be lase at a new wavelength, 808 nm used to excite solid state lasers such as Nd:YVO and 975 nm used to excite fiber laser such as Yb fiber laser and Er-Yb fiber lasers, and also in applications in several fields such as military, industrial and biomedical engineering fields. For the 808 nm diode laser the output wavelength varied with changing the temperature while the 975 nm has a very large stability against the change of the operating temperature. We obtained an optical power up to 6 Watt (cw). The electrical characterization of the diode laser modules was examined by measuring the dependence of the laser driving current on the operating voltage. The optical characterization was investigated at different temperatures. These included the laser output power versus the driving current, the output optical power versus electrical input power, the laser output spectrum, the laser beam profile and the dependence of the output power on the temperature. The measured diode laser of 975 nm parameters at 25oC were (0.3A) threshold current, (35.84%) overall slope efficiency and (975.34 nm) central wavelength with line width of (1.3 nm) at FWHM. The variation of the output power, spectrum with temperature are presented. The measured diode laser of 808 nm parameters at 25oC were (1.3A) threshold current, (42%) overall slope efficiency and (807.96nm) central wavelength with line width of (3.59nm) at FWHM. The variation of the above mentioned parameters with temperature are presented

Abstract
The effects of laser irradiation on are of great interest, as they allow for the optimization of hyperthermia treatment. Thermal effect of laser radiation is now used routinely in surgery to incise, coagulate, or vaporize tissues. The laser irradiation power is converted into heat in the target volume with resulting coagulative, necrosis, secondary degeneration and atrophy, and tumor shrinkage with minimal damage to surrounding structures [1]. Accordingly, the main purpose of this study is to develop a finite element model to simulate the laser distribution through the tumor tissue and the heat transfer due to this laser irradiation. Also, we studied the effects of varying laser intensity and cooling conditions at the breast surface. This can be achieved by using finite element models using COMSOL Multiphysics (FEM lab) software

Abstract
It has been shown that tumor cells are resistant to radiation and that increasing tumor oxygen levels via laser-mediated hyperthermia treatment increases tumor cell radio sensitivity. Hence, studies of the effects of laser irradiation on tumor oxygen levels are of great interest, as they allow for the optimization of hyperthermia treatment. Accordingly, in this study is to develop a finite element model to simulate the heat transfer due to laser irradiation of tumor tissue, the blood flow through a tumor capillary, and the effect of changing temperature on blood flow rates and oxygen delivery to tumor tissue and. This can be achieved by using finite element models using COMSOL Multiphysics software (FEM lab).

Abstract
For the sake of developing the process of medical analysis of biological solutions (Blood, Urea) there should be more substitutions for the current methods using the chemical agents' addition to the samples. An important and fundamental development in medical research is the widening of the field of activity. The medical researcher is no longer content with the study only of the sick individuals; he is also concerned with the problem of keeping the healthy person fits. This shift in behavior needs "mass production" methods, since he will be often working with large group of communities and not only individual patients. Several experiments have been performed in using computers to process medical information. Light spectroscopy and imaging with computerized systems support this process with more accuracy and the storage ability. Optical coherence tomography (OCT) is an emerging technology that can generate high resolution images of tissues in real time. OCT is analogous to ultrasound imaging, except that it uses the echo delay of light instead of sound to generate images. Fourier transform aided with power spectrum density built the theoretical way to achieve the pattern recognition of different materials doped in one solution.
