Implementation of viscoelastic Hopkinson bars
… soft or low impedance materials using metallic bars in a split Hopkinson pressure bar setup, poor signal to noise ratios and impedance mismatching occur. One solution is to use polymeric Hopkinson bars. In this dissertation, Polycarbonate, Polymethyl Methacrylate and Nylon are considered for use …

Bayesian error bars for regression
… are expressed in terms of the error bars, which specify the standard deviation of the distribution of predictions about the mean. Accurate estimate of error bars is of practical importance especially when safety and reliability is an issue. The Bayesian view of regression leads …

Mothers Behind Bars: The Lived Experience
Purpose</p><p> Few research studies have been conducted by nurses that focus on incarcerated women. In fact, there are a limited number of research studies with a focus on the incarcerated female by any individual group of health professionals. The purpose of this qualitative study was to explore …

Overhung-boring bars: The performance of undamped and damped bars under static and dynamic conditions when machining metals
… of some new designs of slug damped boring bars with a 10 to 1 overhang ratio. The bars were mounted on a centre lathe. The static behaviour of a boring bar in relation to the geometric form errors that might be produced during boring was studied both analytically and experimentally. …

CATHODIC PROTECTION OF REINFORCEMENT BARS IN CONCRETE
This research involved investigation of various aspects of cathodic protection in corrosion prevention of the steel reinforcement in concrete. The performance evaluation of cathodic protection, a very important aspect in its operation was widely dealt with. Various criteria used in the cathodic …

ANCHORAGE OF HEADED REINFORCING BARS IN CONCRETE
Headed reinforcing bars serve as a viable alternative to hooked bars for anchorage in concrete because they provide a more efficient anchorage mechanism and limit congestion of the reinforcement. This study is part of a comprehensive study of the anchorage behavior of the headed bars. The work …

Generation of sand bars under surface waves
(cont.) Experiments were performed in a large wave flume to validate the theory and to study additional aspects of sand bar evolution. The wave envelope and bar profile were recorded for low and high beach reflection, monochromatic and polychromatic waves, and several sediment grain sizes. In …

Star formation in the bars of nearby galaxies
… we quantify the star formation activity in bars as a function of the host stellar mass and the morphological type. We use a sample of 70 barred spiral galaxies in the nearby universe taken from the Spitzer Survey of Stellar Structure in Galaxies (S⁴G). The data are combined with Hα data from …

Spectral Element Analysis of Bars, Beams, and Levy Plates
This thesis is primarily concerned with the development and coding of a Levy-type spectral plate element to analyze the harmonic response of simply supported plates in the mid to high frequency range. The development includes the governing PDE, displacement field, shape function, and dynamic …

Bond between reinforcing bars and concrete under impact loading
The bond between reinforcing bars and concrete under impact loading was studied for plain, polypropylene fibre reinforced, and steel fibre reinforced concretes. The experimental program included setting up an impact test system, in which an impact load with considerable energy could be generated, …
