This study presents a novel application of mesh-free method using the smoothed-radial basis functions for the computational homogenization analysis of materials. The displacement field corresponding to the scattered nodes within the representative volume element (RVE) is split into two parts including mean term and fluctuation term, and then the fluctuation one is approximated using the integrated radial basis function (iRBF) method.

Unexpected defects of concrete in a completed bored pile can arise during the construction stage. Therefore, post-construction testing of bored pile concrete is an important part of the design and construction process. The Cross-hole Sonic Logging (CSL) method has been the most widely used to examine the concrete quality.

This body of work is the culmination of a part-time five year investigation into the use of mirroring in digital art composition and its potential to generate affective intensity.The research has occurred through a series of installative works and artefacts produced with digital media in which mirrored operations have been employed in a variety of different ways. The aim of these explorations was to develop and articulate a compositional approach based in acts of mirroring, with the aim of extending affective invitations to the viewer.

This study investigated trace essential metals (Cu, Zn and Cr) and non-essential metals (Pb, Cd and Hg) in water, sediment and tissues of water spinach, snake head fish and swamp eel from the Saigon River. Sampling was conducted from January to December 2004 at three sites. Three water and sediment samples, edible parts of twenty water spinach (Ipomea aquatica) samples (leaves and stems), twenty snake head fish (Channa striata) and twenty swamp eels (Monopterus albus) were collected at each site.

The aim of the research was the processing of the vibration signatures from healthy and damaged composite beams acquired with the help of a Scanning Laser Vibrometer (SLV) upon excitation and analysis of the mode shapes acquired for damage detection. The displacement mode shapes acquired were then converted into curvature mode shapes with the help of a Central Difference Approximation method (CDA).

The purpose of this study was to explore of the role of language switching in a group of Iranian bilingual students while they were involved in mathematical problem solving. Language switching has been viewed as a common practice in bilingual students in their classroom, particularly for mathematics learning. In bilingual students, using their first language to solve at least part of a problem may facilitate mathematical thinking and lead to a successful problem solving process.

In the course of current research the procedure of obtaining of the piecewise linear vibration systems time and frequency responses have been developed. The method is partly analytical and partly numerical and is based on combining of linear solutions of different sections in a cycle of motion. In a row with the method of obtaining of the exact steady state time and frequency response, also it is provided sensitivity analysis of the vibration isolator.

This thesis presents an evaluation of the mapping performance of a variety of SLAM algorithms that are freely available in the Robot Operating System (ROS), in conjunction with ranging data from various ranging sensors suitable for use onboard small UAS. To compare the quality of the generated maps, an existing metric was initially employed, however deficiencies noted in this metric led to the development of two new metrics. A discussion of both the existing and new map quality metrics, and the advantages and disadvantages of each, is presented as part of this thesis.

This research investigates a means of negating such shortcomings and reaping the benefits of both LPBF additive manufacturing and traditional manufacturing methods by joining such parts together using laser welding in the autogenous mode (no fillers required). Based on the literature review conducted in this field and the gaps identified, a two-stage methodology was utilised, as per following.

Once the mechanical properties of printed TPU are characterised, a novel, low cost, and environmentally friendly method for concrete casting using printed TPU moulds is proposed in this thesis. The findings of this thesis will provide clear guidelines for the selection of processing parameters for additively manufactured TPU parts and the method of casting complicated concrete structures with additively manufactured TPU mould.

The noise level of the temperature measurement system was approximately 0.08 mK (peak to peak). The temperature of the core part rose by approximately 8.6 mK at 800 MU (monitor unit) for 6-MV Xray beams, and it increased as X-ray energy increased. The temperature rise showed less spread when it was normalized to the accumulated charge, as measured by an external monitoring chamber.

To provide high shunt impendence with low power losses, an 81.25 MHz continuous wave (CW) radio frequency quadrupole (RFQ) accelerator has been designed and machined as parts of the Low Energy Accelerator Facility (LEAF). In this paper, the mechanical structure and the main processing technology of the RFQ cavities are described according to the physical and geometric parameters requirements of the RFQ. The fabrication of the RFQ has been completed and the test results agree well with the design requirements.

This study simulated a control rod assembly (CRA), which is a part of reactor shutdown systems, in immersed and fluid flow conditions. The CRA was inserted into the reactor core within a predetermined time limit under normal and abnormal operating conditions, and the CRA (which consists of complex geometric shapes) drop behavior is numerically modeled for simulation.
