The seismic performance of a two-story 2D frame and a five-story 3D frame–shear-wall structure founded on spread (isolated) footings is investigated. In addition to footings conventionally designed in accordance with “capacity-design” principles, substantially under-designed footings are also used. Such …

The overriding purpose of the thesis research is to develop new design concepts for improved and sustainable asphalt mixes. To accomplish this goal, it became necessary to reach some prerequisite goals. Determining what a sustainable asphalt means, and how that ideal is connected with the field of asphalt …

Extrudate swell simulations and experiments have been performed with a viscoelastic tire rubber compound at high flow rates through a circular die. A 3-mode PTT model was fitted onto rheological data of the rubber. The PTT model covers the range of shear rates present in the simulation. Convergence of …

As a means to decrease the amount of waste tires and to re-use tire rubber for new tires, devulcanization of ground passenger car tires is a promising process. Being an established process for NR and EPDM, earlier work has shown that for ground passenger car tire rubber with a relatively high amount …

Microfluidic devices have the potential to adopt more accurate physiological conditions of the human intestine through the use of continuous flow and by producing mechanical stress to the cells. This study evaluated the translocation properties of a microfluidic gut-on-chip device in comparison with …

This paper investigates the limits and efficacies of the Fiber Reinforced Polymer (FRP) material for strengthening mid-rise RC buildings against seismic actions. Turkey, the region of the highest seismic risk in Europe, is chosen as the case-study country, the building stock of which consists in its …

Coupling beams between shear walls are one of the key elements for energy dissipation in tall buildings. A representative mathematical model of coupling beam should represent flexure, shear and interface slip/extension mechanisms simultaneously. This goal can be achieved by using either detailed finite …

Barges are used in order to transport all types of offshore structures and equipment. Structures which are transported are becoming larger and heavier. Therefore, there is need for barges that can handle these structures. This research will explore the possibilities to increase barge capacity by adding …

Purpose: Pressure ulcers are a high cost, high volume issue for health and medical care providers, having a detrimental effect on patients and relatives. Pressure ulcer prevention is widely covered in the literature, but little has been published regarding the risk to patients in the radiographical setting. …

Force transmission across the wrist during a grasping maneuver of the hand was simulated for three children with juvenile idiopathic arthritis (JIA) and for one healthy age-matched child. Joint reaction forces were estimated using a series of springs between articulating bones. This method (i.e., rigid …
