Study of influence of cold rolling and annealing on ultimate tensile strength of AA2024 alloy using Box-Behnken experimental design
This study investigates the effects of thermo-mechanical processing parameters, specifically cold rolling and annealing, on the ultimate tensile strength (UTS) of AA2024 alloy, employing a Box-Behnken experimental design. The deformation during cold rolling, the annealing temperature, and the time annealing were varied to evaluate their individual and combined effects on the UTS.

Evaluating the sub-chronic toxicity of the Boga -TN tablets in experimental animals
The study was carried out in Wistar rats for 4 consecutive weeks by oral administration at the doses of 0.77 and 2.32g/kg/day. After treatment, no significant treatment-related abnormalities were observed at both doses of Boga-TN, compared to the control group, except for the white blood cells, with lower neutrophil but higher lymphocyte values observed in the treated animals. Histopathology assessment did not show any significant variation between control and treatment groups during the study period.

Experimental study on the application of TRC to enhance the load-bearing capacity of reinforced concrete slabs
To enhance load-bearing capacity and prevent structural damage, reinforced concrete elements are often strengthened with additional layers of material. This study investigates the bonding performance between Textile Reinforced Concrete (TRC) and reinforced concrete slabs through four-point bending tests.

Master's thesis of Engineering (Aerospace): Modelling and experimental analysis of aerospace composites in fire
The aim of this Master of Engineering (MEng) - Aerospace thesis is to study the structural response and failure of aerospace grade composites during exposure to fire. Key aspects of the research are to analyse the thermal and mechanical responses of laminates and sandwich composites in high temperature and fire environments, which result in softening and structural failure. The research is concentrated on carbon/epoxy laminates and sandwich composites, which are the most common composite materials used in aerospace structures. To achieve the general aim of this research project, the thermal response of aerospace composites will be validated using existing thermal models for fibreglass composites.

Master's thesis of Engineering: Experimental studies in aid of improving nasal drug delivery
The nasal route for drug administration has the potential for local and systemic delivery of a wide variety of therapeutics. Nasal spray drug delivery has the potential to administer drugs to the bloodstream, avoiding the use of painful needles. While there is great potential, studies in the area are limited and somewhat conflicting. This study aimed to support the improvement of nasal drug delivery through experimental work on a model nasal cavity and through experimental characterisation of nasal spray behaviour. Four different brands of nasal spray were investigated. Particle distribution studies via laser diffraction and high speed videography were performed at three different actuation forces, representing the average adult, child and maximum force applied to the spray device.

Extension of Bayesian inference for multi-experimental and coupled problem in neutronics a revisit of the theoretical approach
In this document, we rewrite Orlov theory to extend to multiple experimental values and parameters adjustment. We found that the multidimensional system expression looks like can be written as the monodimensional system in a matrix form.

Summary of PhD thesis: Personal values in service consumption - An experimental study in Vietnam
The study must achieve specific objectives: adjust the scale of 'personal values', then find what aspects of'personal values' are relevant to the current market in Vietnam. Testing the concept of 'personal values' as well asits aspects corresponding to the behavioral model in some typical service industries in Vietnam. Check the reliability of the research model used in testing 'personal values' with service consumption behavior.

Research " THE USE OF INTENAL AUDIT FINDINGS IN GOVERNMENTAL ORGANIZATION : AN EXPERIMENTAL STUDY "
THE USE OF INTENAL AUDIT FINDINGS IN GOVERNMENTAL ORGANIZATION : AN EXPERIMENTAL STUDY In modeling the effects of parental preferences on equilibrium outcomes under Tiebout choice, it is important to account for two key issues that do not arise under choice programs like vouchers. The first is that residential choice rations access to highlydemanded schools by willingness-to-pay for local housing.4 As a result, both schools and districts in high-choice markets (those with many competing school districts) are more stratified than in low-choice markets....
