Theoretical and experimental investigation of acoustic performance of multi-chamber reactive silencers
No full textArslan, Hakan/0000-0002-2019-1882; Ranjbar, Mostafa/0000-0002-9670-7371The acoustic attenuation and performance analysis for blast flow field inside a silencer is investigated. In this regard, a silencer system is designed to reduce the exhaust noise. The effect of position and the number of the baffles for each design on sound transmission loss have been investigated using theoretical, numerical and experimental studies. Three prototypes are manufactured for the experimental studies. Using the measured results, insertion loss graphics have been obtained. The silencer performances are dependent on the baffle geometry, number and the positions. The experimental results are in a good agreement with the simulation results. It is observed that by considering the same number of baffle numbers but located at various locations, the model which shows the best sound transmission loss performance has also the best insertion loss performance and has the least value of peak sound pressure level.

Agosti. 1 ☿, Sharjah Desert Park, 5–6.x.2004, AvH; 1 ☿, 3.iii.2005, CAC. 1 ☿, al- Za'aba, 100 m, sandy soil with Rhaisa stricta [23°43'20"N, 55°33'49"E], 22.iii.1995, leg. D. Agosti. Description: A large worker from al-Ain was selected as holotype. The measurements are as follows: total length 8.40; head width 3.60; head length 4.20; scape length 3.84; funicular segment I 0.40; funicular segment II 0.23; petiole length 1.10; petiole width 0.72. Colour dark reddish brown. There are no exterior hairs on the scapes or hind tibia. The gaster, petiole and propodeum have dorsal hairs. Remarks: This species thought to correspond with C. desertorum has to be described as a new species. In fact it is one of the commonest Cataglyphis in southern Arabia. The main distinguishing feature compared with other dark Cataglyphis is the slender petiole, which has the anterior face more sloped than in other similar species such as C. niger (André, 1882) and C. savignyi (Dufour, 1862). Biology: Cataglyphus laylae nov. spec. does not appear to occur in open sandy desert and is most abundant in disturbed habitats such as man-developed plantations and open cultivated fields. Distribution: This species was recorded by Collingwood (1985) as C. desertorum from Saudi Arabia and Oman and as Cataglyphis spec. by Collingwood & Agosti (1996). Etymology: The new species is named after a village settlement called “Layla”, just north of Riyadh (Saudi Arabia) in the area where the author (CAC) first encountered it in numbers in an Acacia plantation.Published as part of Cedric A.

A Comparative Study on Optimization in Structural Acoustics
No full textThis dissertation presents an exhaustive comparative study on optimization in structural acoustics. A combination of a commercially available finite element software package and additional user-written programs is used to modify the shape of a structure. This is done iteratively and without manual intervention to achieve significant improvements of the objective function. The optimization process continues automatically until the predefined maximum number of function evaluations is reached.
The design variables are the structure's local geometry modification values at selected surface key-points. The objective of the optimization includes the minimization of the root mean square level of structure borne sound (a general measure of the vibrational sensitivity of a structure). In addition, the structural mass remains constant and the allowable ranges of design variable values are restricted by prescribed upper and lower limits. The optimization procedure is tested on the finite element model of a rectangular plate made of steel.
Twelve different optimization methods are tested against each others. These methods are considered either as approximate or exact. The approximate optimization methods use either an approximated value of objective function, e.g., hybrid design of experiments and hybrid neural networks, or the approximated values of the first and the second derivatives of the objective function, e.g., method of feasible directions, sequential quadratic programming method, Newton method, limited memory Broyden-Fletcher-Goldfarb-Shanno method for bound constrained problems, method of moving asymptotes, mid-range multi- oints method and controlled random search method. The exact optimization methods, e.g., genetic algorithms, tabu search and simulated annealing, are derivative-free methods and they use the exact value of objective function. Furthermore, a statistical approach is followed for the comparison of methods. Advantages and disadvantages of each optimization algorithm are reported in details.
The rate of convergence (a measure of optimization speed) and the robustness level of each optimization method are evaluated. Some optimization methods are classified as fast, medium and slow. Method of moving asymptotes and mid-range multi-points method are introduced as the fastest methods.
Finally, it is experienced that the use of e ective structural-acoustic analysis methods can drastically reduce the total optimization time. If the powerful optimization methods become equipped with effective (fast and reliable) structural acoustic analysis methods, then they can present more desirable optimization results in a shorter period of computation time. In this case, they can even be considered as a suitable replacement for the complex and the multi-stages hybrid optimization algorithms
Digital amplification for pathogen detection in bloodstream infections from whole blood
No full textSensitive and specific detection of bacteria is essential for control and treatment of bloodstream infections. Sepsis, a diagnostic challenge of blood stream infections, causes thousands of deaths each year. The gold standard for detection and identification of microorganisms is blood culture, which can take up to 5 days to yield a diagnosis or a negative result. Molecular diagnostic methods and nucleic acid assays developed to detect pathogens often require enrichment through blood culture prior to DNA extraction. Nonetheless, state of the art diagnostic tests that detect pathogens directly from blood are available with limitations. Increased amount of sample processing and purification is required before detection of pathogens and turnaround time to results can be up to 8 hours. Moreover, the sensitivity and specificity of such assays are broad in range. Thus, there is a need for a rapid detection method that can identify pathogens from whole blood within 1-2 hours, with minimal sample processing and high sensitivity and specificity.
In this work, we demonstrate detection of bacterial pathogens from whole blood through loop mediated isothermal amplification without the steps of DNA purification and extraction. Whole blood with pathogens is dried to tubes, creating separated phases of the cellular debris of blood from the amplification reaction and allowing for separation of background human DNA from target DNA as well as better detection of amplicons that are not masked by red blood cells. We show that this method is robust, having a detection limit of 1 cfu of pathogens in 4uL of whole blood. In preparation of processing higher blood volumes in a digital amplification method, we also show characterization experiments and preliminary results of amplification of pathogens from whole blood on chip.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2021-12-01The student, Ariana Mostafa, accepted the attached license on 2019-12-04 at 05:15.The student, Ariana Mostafa, submitted this Thesis for approval on 2019-12-04 at 05:29.This Thesis was approved for publication on 2019-12-05 at 09:04.DSpace SAF Submission Ingestion Package generated from Vireo submission #14686 on 2020-02-28 at 17:23:14Made available in DSpace on 2020-03-02T22:15:06Z (GMT).

The Egyptian Military in Popular Culture:Context and Critique
No full textThis book examines a key question through the lens of popular culture: Why did the Egyptian people opt to elect in June 2014 a new president (Abdel Fattah al-Sisi), who hails from the military establishment, after toppling a previous military dictator (Hosni Mubarak) with the breakout of the 25 January 2011 Revolution? In order to dissect this question, the author considers the complexity of the relationship between the Egyptian people and their national army, and how popular cultural products play a pivotal role in reinforcing or subverting this relationship. The author takes the reader on a ‘journey’ through crucial historical and political events in Egypt whilst focusing on multi-layered representations of the ‘military figure’ (the military leader, the heroic soldier, the freedom fighter, the conscript, the martyred soldier, and the Intelligence officer) in a wide range of popular works in literature, film, song, TV drama series, and graffiti art. Mostafa argues that the realm of popular culture in Egypt serves as the ‘blood veins’ which feed the nation’s perception of its Armed Forces
