Towards Study an Ant Colony Optimization
Manoj Kumar Bisht
DOI: 10.17148/IARJSET.2020.7101
Abstract: Ant Colony Optimization (ACO) is a paradigm for designing met heuristic algorithms for combinatorial optimization problems. The essential trait of ACO algorithms is the combination of a priori information about the structure of a promising solution with a posteriori information about the structure of previously obtained good solutions. Heuristic algorithms are algorithms which, in order to escape from local optima, drive some basic heuristic: either a constructive heuristic starting from a null solution and adding elements to build a good complete one, or a local search heuristic starting from a complete solution and iteratively modifying some of its elements in order to achieve a better one. The met heuristic part permits the low-level heuristic to obtain solutions better than those it could have achieved alone even if iterated. Usually, the controlling mechanism is achieved either by constraining. The particular way of defining components and associated probabilities is problem-specific, and can be designed in Different ways, facing a trade-off between the specificity of the information used for the conditioning and the number of solutions which need to be constructed before effectively biasing the probability distribution to favor the emergence of good solutions. Different applications have favored either the use of conditioning at the level of decision variables, thus requiring a huge number of iterations before getting a precise distribution, or the computational efficiency, thus using very coarse conditioning information.

Mohamed R. A. Rashwan, Manal.A.M.Hassan
DOI: 10.17148/IARJSET.2020.7106
Abstract: In this study, two white sorghum (sorghum bicolor L) cultivars namely: Dorado and Giza 15 were subjected to soaking treatment for 24 hours then knowing its effect on chemical, minerals composition and phosphorus fractions. Dorado Treated Whole Flour (DTWF) was chosen as a best sample to prepare sweet fermented bread and chicken burger with ratios 10, 20, 30 and 40% from it. Further, the resulting fresh breads were used to determine sensory, physical properties, phosphorus fractions and starch content as well as gelatinization properties by DSC. The obtained data revealed that there were significant (P<0.05) differences between flour mixtures and also among the fresh bread samples. The gelatinization enthalpies and temperatures varied significantly (P<0.05) between wheat flour, DTWF and flours mixtures. For flours mixtures the Onset Temp (To) was ranged from 30.02 to 45.67°C; Peak Temp (Tp) from 66.08 to 80.13°C; End Temp (Te) from 136.21 to 141.36 as compared to 44.42; 79.12; 155.46°C , 31.68; 74.13; 130.84°C for wheat flour and DTWF sample; respectively. On the other hand, the gelatinization temperatures were significantly (P<0.05) different between the bread samples especially Te which found with higher degrees when compared to flours and flours mixtures. The gelatinization temperatures and change of enthalpies varied significantly between stored bread samples. The To was ranged from 30.10 to 38.49°C; Tp 109.01 to 120.17°C; Te 139.55 to 147.22 °C. It is clear that the Te was decreased significantly in bread stored 4 days when compared with the same bread at 0 time of storage. Consequently, the ∆HP was significantly decreased with range 4.43 to 4.70 J.g-1 for the stalled bread, which stored for 4 days. The retrograde% of supplemented stored bread was significantly (P<0.05) higher ranged from 90.00 to 94.00 when compared to control WF bread with value 88.60%. The consumer acceptability which expressed by total score was highest for burgers containing 10%, 20% supplemented burgers, with values 59.30 and 56.60, respectively, as compared with 61.21 for control (100% chicken breast meat). The best results were obtained for bread and burger samples supplemented with 10% and 20% replacement ratio. The chemical composition of the products was found in reasonable amounts, which confirms the highly nutritional value of these products, as well as, desirable properties that the consumer will accepted them.

Abstract: Currently the consumer needs for anti-diabetic products are very large and require answer from healthy food provider answers. Products that are commonly known are tea and stevia. Tea and stevia have advantages as an antioxidant and anti-diabetic. The use of commercially available products is very depended on sensory characteristics which can be accepted by consumers. How much is consumed (food intake) depends on the sensory sensitivity of the consumer. Tea and stevia products are products that contain poly phenols which give a sense of briskness or bitterness. At the time of serving alone, stevia tea and steeping have a certain value, which will be different if brewed simultaneously. The study aims to determine the sensory acceptance threshold value, to steeping a mixture of black tea and dried stevia leaves. The study was conducted using the absolute threshold test, using a proportion of the concentration of stevia black tea between 20:1 to 4:1(w/w) and maximum weight of 2 grams. The mixture was brewed using 200 mL hot water with a temperature of 900 Celsius for 5 minutes. The steeped product was then tested by 80 untrained panelists to find out the absolute threshold for sweet and bitter taste. From the research it was known that the absolute threshold value for sweetness of stevia-black tea was 0.39% (w/v) and bitterness ofstevia - black tea was 0.42% (w/v).

DOI: 10.17148/IARJSET.2020.7114
Abstract: Replacement of natural aggregates with rubber tyre aggregates is an alternative way to dispose of waste tyre safely. Research has found that using rubber in concrete will enhance and reduce its density. This study considers how to minimize the loss of strength of concrete using rubber tyre crumb aggregates. In the recent research study rubber modified concrete was made by two different ways: 1) by replacing natural fine aggregate in normal concrete of M35 grade with untreated crumb waste tyre particles and 2) by replacing natural fine aggregate in normal concrete of M35 grade with crumb rubber particles treated with synthetic resin (PVA). The replacement of fine aggregates in both the cases was done at 5% ,10% and 15%.the rubber reduced the density and compressive strength of concrete while increased the flexural strength, water absorption and damping ratio. The size of crumb rubber varies from 4.75 mm to 0.15 mm. rubberized concrete recommended to be used in circumstances where vibration damping was required such as in bridge construction. Waste rubber tyres can be incorporated in concrete either as coarse aggregates or fine aggregates. Waste rubber aggregates have been categorized in to four types based upon their particle size. Crumb waste rubber is a material derived by reducing/shredding scrap tires or other rubber into uniform granules. The source of scrap tyres are: passenger car tires, truck tires and off-the-road tires. On average, about 10 to 12 pounds of waste crumb rubber can be manufactured from one passenger tire. Realizing the problem of strength reduction on the addition of tyre particles in concrete appropriate measures are needed in order to improve the strength of rubber modified concrete.
