Fault-tolerant Semantic Mappings Among Heterogeneous and Distributed Local Ontologies
Full text linkABSTRACT Overcoming semantic mapping faults, i.e. semantic incompatibility, is a vital issue for the success of semantic-based peer-to-peer systems. There are various research efforts which address the classification and the resolution of the semantic mapping fault problem, i.e. translation errors. All of the precedent research related to semantic mapping faults demonstrates one significant shortcoming. This flaw is the inability to discriminate between non-permanent and permanent semantic mapping faults, i.e. how long do semantic incompatibilities stay effective and are the semantic incompatibilities permanent or temporary? The current research examines the destructive effect of semantic mapping faults on the Emerging Semantics, i.e. bottom-up construction of ontology and proposes a solution to detect temporal semantic mapping faults. The current research also demonstrates that fault-tolerant semantic mapping will result in Emerging Semantics which are more complete and agreeable than those domain ontologies that are built without consideration for fault-tolerant semantic mapping

No full textImprovisation facilitates divergent thinking and creativity: Realising a benefit of primary school arts education
No full textAbstract The benefit of arts education for cultural engagement, wider academic achievement, and as a contributor to the creative economy is a subject of significant debate. In the present work we focus on the potential for simple arts-based improvisation activities to enhance divergent thinking skills and creativity in primary school age children. In a first experiment we compared the effect of children taking part in an improvised vs. non-improvised dance class on their subsequent performance on the Instances Tas
Pulverized Coal Combustion: The Influence of Flame Temperature
Full text linkA laboratory combustor was used to investigate the factors that influence the conversion of fuel nitrogen in coal during coal combustion. Fuel NO was isolated by experimentation utilizing Argon/Oxygen/Carbon Dioxide mixtures as the oxidant, and care was taken to compare cases with air at matched conditions. For both well mixed and slowly mixed flame types, fuel NO contributed over 75% of the total NO emissions for all conditions examined. Fuel NO was insensitive to temperature changes except when the adiabatic flame temperatures were above 2480 0 K (4000°F). At the highest adiabatic flame temperature, 2580 0 K (4200°F), a 10% increase in fuel NO was observed. Four different coals and one coal char were investigated. Fuel NO could not be correlated with fuel nitrogen content alone, even though aerodynamic conditions were kept constant. Fuel nitrogen conversion to NO during pulverized char combustion was 12-16% at a stoichiometric ratio of 1.15 compared to 28% for a pulverized coal of the same nitrogen content. Furthermore, in contrast to the coal results, NO emissions from char combustion were not greatly influenced by changes in injector design. The implication is that although conversion of fuel nitrogen to NO may be relatively low during the char burnout regime of coal combustion, the residual "char NO" may be especially resistant to abatement by modifications of the burner aerodynamics
Comparative Study of Enophthalmos Treatment with Titanium Mesh Combined with Absorbable Implant vs. Costochondral Graft for Large Orbital Defects in Floor Fractures
Full text linkABSTRACT Introduction: Several treatment options are available for the optimal treatment for orbital fractures, depending on aesthetic and functional results after orbital wall reconstruction. The objective of this study is to compare the effect and safety of large orbital fl oor fractures with titanium mesh combined with poly-L-lactic acid/polyglycolic acid copolymer implants (Lactosorb®) vs. autologous costochondral graft. A wide range of permanent and biodegradable materials have been used successfully for orbital fl oor reconstruction, however they present with disadvantages for reconstruction of large defects, even if combined. Results: Follow up of 21 patients (12 weeks) 17 male, 4 female, ages 22-63 was made. Enophthalmos, main objective of this study, was identifi ed with statistical signifi cance presenting 0% (n=0) post-op Group B patients and 30% (n=3) for Group A (p=0.049). Statistical signifi cance was found referring to inpatient days between two groups being less for costochondral reconstruction patients (p=0.02). No pain in patients undergoing alloplastic surgery. An interesting result was that donor area analogue pain scale for costochondral graft was 2.9/10. Patients and Methods Conclusion: Surgical outcome and complications where evaluated comparing different materials for orbital fl oor reconstruction. Costochondral graft is a suitable choice when orbital reconstruction is indicated
Studies on Some Benzoxazine-4-one Derivatives with Potential Biological Activity
No full textAbstract 2-(4-Toluenesulphonyloxy phenyl)-3,1-benzoxazine-4-one 2 was prepared and reacted with some nitrogen nucleophiles, e.g., ammonia, o-phenylendiamine, some heterocyclic amines, hydrazine hydrate and hydroxylamine hydrochloride and sulphur nucleophile, e.g., phosphorous pentasulphide. Structures of the newly synthesized compounds were established by elemental analysis and spectral data. All new prepared compounds were subjected to antimicrobial activity evaluation where compounds, 8, 9, 10 and 18 exhibited good activities against Bacillus Thuringenesis and 5, 10, 11, 14, 15, 17 and 18 exhibited good activities against Klebseilla Pneumonia. On the other hand, the results for antifungal activities revealed that, compounds 5, 6, 7, 16 and 17 exhibited good activities against Trichoderma Herzianum and Trichoderma Virdi
