Performance of short piled raft foundation system on peat soil under static load
… and replace, especially for foundation under static point load. This research was conducted to explore a proposed Short Piled Raft (SPR) foundation system, which is a combination of a pile foundation and raft foundation, with a pile length short enough. The objectives of this research were to …

Effects of topical fluoride prophylactic agents on the mechanical properties of orthodontic nickel-titanium closed coil springs
… orthodontic closed coil springs. Unloading force and rigidity were measured at 1, 4, 8, and 12 weeks, after springs were exposed to phosphate buffered saline (PBS), PBS combined with acidulated fluoride (PBS+APF) or sodium fluoride (PBS+NaF) with or without spring static loading. …

Statnamic Lateral Load Testing and Analysis of a Drilled Shaft in Liquefied Sand
Three progressively larger statnamic lateral load tests were performed on a 2.59 m diameter drilled shaft foundation after the surrounding soil was liquefied using down-hole explosive charges. An attempt to develop p-y curves from strain data along the pile was made. Due to low quality and lack of …

The fatigue performance assessment of corrosion damaged RC beams, patch repaired and externally strengthened using CFRP
… CFRP strengthened, were subjected to a monotonic load in order to establish the ultimate static load at failure for the RC beams. The ultimate static load at failure was then used to derive the maximum imposed cyclic fatigue loading that was applied. The remaining four RC beams were then subjected …

The Correlation Between Biomechanical Loads and Psychophysical Ratings
… methodology, relate to physical (biomechanical) loads. A fundamental assumption of this method is that humans are capable of estimating biomechanical and physiological loads that are placed on the body. Based on this assumption, estimates that are obtained through the methodology are used as an …

Parallel dynamic load-balancing for adaptive distributive memory PDE solvers
… thesis is concerned with the issue of dynamic load-balancing in connection with the parallel adaptive solution of partial differential equations (PDEs). We are interested in parallel solutions based upon either finite element or finite volume schemes on unstructured grids and we assume that …

New Truck Loading Model For Rural Bridges In Saskatchewan
… existing information on estimating the critical load effects occurring on short span bridges, on low traffic roadways, and over specific reference periods makes it difficult to perform the bridge evaluations with an adequate degree of confidence. This study focuses on aspects of the estimation of …

Applicazione delle tecniche elettrosmotiche alla consolidazione dei fanghi di risulta dei processi mineralurgici
… the consolidation process, both under a static load (static consolidation) and a static load plus an electric field (combined consolidation). The research showed that the application of the electric gradient of 1V/cm reduces the consolidation time by about 80%. At the end of …

Nonlinear Finite Element Analysis of FRP Strengthened RC Beams under Static and Cyclic Loads
… behavior of FRP strengthened RC beams under static load. Very few finite element models for analysis of FRP-RC beam have been developed under cyclic load, and also the degradation of material properties of concrete, steel and FRP with number of cycles have been neglected in the existing few …

Comparison of the force and torque transfer for different cam profiles
This study presents static load and torque distribution measurements in groove cams for sinusoidal and cycloidal cam profiles. In this thesis, two different designs and apparatuses were developed and built for the static force and torque measurements in cam-follower systems. It was shown that for …

Network and Load Modeling for Power System Dynamic Analysis
… thesis involves the development of network and load models for power system analysis. Traditional power system models consist of detailed generator models and simple network and load models. In the past this has been acceptable as these models captured observed phenomena. These models do not …
