Optimum Parameters for Freeze-Drying Decellularized Arterial Scaffolds
(2013)Decellularized arterial scaffolds have achieved success in advancing toward clinical use as vascular grafts. However, concerns remain regarding long-term preservation and sterilization of these scaffolds. Freeze drying ... -
Optimum stability in control system design
(Trinity College (Dublin, Ireland). Department of Electronic & Electrical Engineering, 2007)This thesis develops for the first time a general approach to the design of control systems that emphasizes optimum system stability as the primary design criterion. The design method is to select controller parameters ... -
Organic Electrochemical Transistors (OECTs) Toward Flexible and Wearable Bioelectronics
(2020)Organic electronics have emerged as a fascinating area of research and technology in the past two decades and are anticipated to replace classic inorganic semiconductors in many applications. Research on organic light-emitting ... -
Organic-based flexible thermoelectric generators: From materials to devices
(2022)There is a rapidly growing demand for self-powered technologies in wearable electronic devices that can be integrated with the human body to accomplish various functions. Flexible thermoelectric generators produce electricity ... -
ORIENTATION ESTIMATION USING KALMAN FILTERS WITH MULTIPLE SENSORS
(2015)The ability to repeatedly and accurately position robotic end-effectors is a key requirement for modern industrial automation. Parallel developments in domestic and service robotics are opening up exciting possibilities ... -
Orientation polarization from faster motions in the ultraviscous and glassy diethyl phthalate and its entropy
(2006)Dielectric spectra of the relaxation in glassy and ultraviscous liquid diethyl phthalate show that its relaxation strength , the distribution of times, and the relaxation rate are more sensitive to temperature T in the ... -
The orientational order and the dynamics of the dendritic liquid crystal organo-siloxane tetrapodes determined using dielectric spectroscopy
(2006)The dielectric measurements have been carried out on the two zeroth generation dendrimers with four branched arms (called tetrapodes) based on the siloxane cores. The results are analyzed in the framework of the molecular ... -
Orientational order of a ferroelectric liquid crystal with small layer contraction
(2010)We present spectroscopic and optical studies of a non-layer-shrinkage ferroelectric liquid crystal DSiKN65. The orientational order parameters S, measured with respect to the smectic layer normal using IR spectroscopy on ... -
Orientational/translational relaxation in aqueous electrolyte solutions : a molecular model for microwave/far-infrared ranges
(Royal Society of Chemistry, 2001)A model is given where the complex permittivity of an electrolyte solution is calculated as a superposition of the contributions due to the translation of ions and the reorientation of water molecules, which occur in ... -
Origin and technology of the Georgian brick at Fade Mansion, Dublin, built c. 1728
(2021)This paper studies the provenance and firing technol- ogy of the Fade Mansion brick. The microstructure was studied with scanning electron microscopy (SEM), mineral associations and transformation were ... -
Origin of films on monumental stone
(Earthscan, 2006)This paper investigates the origin of superficial films on different rock types from rural and urban locations in Spain and Ireland, focusing mainly on oxalate films. There is little agreement on the origin of oxalate films ... -
Osteoarthritis-associated basic calcium phosphate crystals alter immune cell metabolism and promote M1 macrophage polarization
(2019)Objective: A number of studies have demonstrated that molecules called ‘alarmins’ or danger-associated molecular patterns (DAMPs), contribute to inflammatory processes in the OA joint. Metabolic reprog-ramming of immune ... -
Output-only Finite Element Model Updating for Post-Earthquake Monitoring
(2023)After any seismic event, it is critical to rapidly assess the damage condition of bridges. This process could be facilitated using digital technologies to eliminate the barriers of manual inspections. The post-event response ... -
An overview of current techniques for ocular toxicity testing.
(2015)Abstract Given the hazardous nature of many materials and substances, ocular toxicity testing is required to evaluate the dangers associated with these substances after their exposure to the eye. Historically, animal tests ... -
An overview of the University College Dublin hollow cylinder apparatus
(2001)Most sedimentary soils are inherently ansiotropic. Their response to loading will depend on the directions of the principal stresses. In most geotechnical problems the principal stresses gradually rotate during loading. ... -
An Overview of the University College Dublin Hollow Cylinder Apparatus
(2001)This presentation is divided into two sections. First, an example showing the influence of the principal stresses on the strength and deformation characteristics of a soil is discussed. Secondly, an overview of a unique ... -
Oxygen tension differentially regulates the functional properties of cartilaginous tissues engineered from infrapatellar fat pad derived MSCs and articular chondrocytes.
(2010)Background For current tissue engineering or regenerative medicine strategies, chondrocyte (CC)- or mesenchymal stem cell (MSC)-seeded constructs are typically cultured in normoxic conditions (20% oxygen). However, within ...
