The Effects of Fluctuating Operation on Reverse Osmosis Membranes
No full textDirectly coupling renewable energy to reverse osmosis may be the most cost effective solution to supply potable water to remote and isolated areas that lack infrastructure and safe drinking water. These systems do not use batteries but rather operate only when sufficient energy is available and store any excess energy as water. Since reverse osmosis membranes are designed to be operated for continuous periods under constant power, it has been unclear how the fluctuating operation will affect the performance of the membranes. In these experiments, a small-scale reverse osmosis unit (maximum production 8 m3/day) was set up in the laboratory to continually recycle and treat a reservoir of artificial seawater (32 800 mg/L NaCl). The power of the high pressure pump feeding the reverse osmosis membranes is fluctuated corresponding to inputs of real wind data entered through an automated computer system. Measurements of pressure, permeate production and conductivity were continually recorded and used to determine if there were changes in the membrane permeability coefficient and salt rejection of the membrane resulting from fluctuating operation. After more than 650 hours of fluctuating operation, no deterioration of reverse osmosis membrane performance was observed.Sanitary EngineeringWater ManagementCivil Engineering and Geoscience
Standardisation of Provenance Systems in Service Oriented Architectures --- White Paper
No full textThis White Paper presents provenance in computer systems as a mechanism by which business and e-science can undertake compliance validation and analysis of their past processes. We discuss an open approach that can bring benefits to application owners, IT providers, auditors and reviewers. In order to capitalise on such benefits, we make specific recommendations to move forward a standardisation activity in this domain
A framework for the real-time analysis of musical events
No full textIn this thesis I propose a framework for the real-time creation of a harmonic structural model of music. Unlike most uses of computing in musicology which are based on batch processing, the framework uses publish/subscribe messaging techniques found in business systems to create an interconnected set of collaborating applications within a network that process streamed events of the kind generated during a musical performance. These applications demonstrate the transformation of data in the form of MIDI commands into information and knowledge in the form of the music’s harmonic structure represented as a model using semantic web techniques.With such a framework, collaborative performances over the network become possible with a shared representation of the music being performed accessible to all performers both human and potentially software agents. The framework demonstratesnovel real-time implementations of pitch spelling, chord and key extraction algorithms interacting with semantic web and database technologies in a collaborative manner. It draws on relevant research in information science, musical cognition, semantic web and business messaging technologies to implement a framework and set of software components for the real-time analysis of musical events, the output of which is adescription of the music’s harmonic structure. Finally, it proposes a pattern based approach to querying the generated model which suggests a visual query and navigation paradigm

No full texteCRM capabilities of SMEs: a model and its relationships
No full textOrganizations today have a diversity of applications available to support the management of customerrelationships, namely electronic-customer relationship management (eCRM) applications. Despite thegrowing need of understanding eCRM in small and medium-sized enterprises (SMEs), eCRM research islargely focused on large organizations. Building on the theory of dynamic capabilities, this paperexamines the relationships among use of the internet infrastructure, eCRM capabilities, and theirresulting benefits through a survey across 286 SMEs in Ireland. Findings present significant theoreticaland practical contributions. It is posited that the ICT infrastructure strongly impacts eCRM capabilitiesof SME’s. Further, it is posited that the level of ICT use impacts on eCRM capabilities. Ultimately, themore proficient the eCRM capabilities, the higher the levels of benefits recorded for SME’s. Our eCRMfocused study provides a valuable theoretical contribution and also aims to inspire further research inthe SME context of this important are
Long-term sensorimotor adaptation in the ocular following system of primates
No full textThe sudden movement of a wide-field image leads to a reflexive eye tracking response referred to as short-latency ocular following. If the image motion occurs soon after a saccade the initial speed of the ocular following is enhanced, a phenomenon known as post-saccadic enhancement. We show in macaque monkeys that repeated exposure to the same stimulus regime over a period of months leads to progressive increases in the initial speeds of ocular following. The improvement in tracking speed occurs for ocular following with and without a prior saccade. As a result of the improvement in ocular following speeds, the influence of post-saccadic enhancement wanes with increasing levels of training. The improvement in ocular following speed following repeated exposure to the same oculomotor task represents a novel form of sensori-motor learning in the context of a reflexive movement
