Abstract

As for the criteria to purchase an air conditioner, noise level has emerged as an important issue, equal to design characteristics and performance. The main feature of the noise of the outdoor unit is a complex characteristic noise due to the operation of the fan and compressor. Air-borne noise is usually caused by the vortex separation on the fan blade, and structure-borne noise is caused by compressor or vibration transmission to the chassis and components. Due to the efforts of researchers and designers who have worked on noise reduction, the sound pressure level (SPL) of outdoor units launched on the market is under 50dB (A). While the SPLs of the noises are similar, consumers can feel the noise differently according to the frequency characteristics. Therefore in this study, it was purposed to evaluate sound quality by a comparative analysis of the noise characteristics, and tests were performed on the same outdoor unit only changing the compressors. To analyze the noise characteristics of the outdoor unit of the airconditioner, sound quality metrics such as Unbiased Annoyance (UA) and Psychoacoustic Annoyance (PA) were applied.

Abstract

We report on an indium-free and cost-effective Cu2O/Cu/Cu2O multilayer mesh electrode grown by room temperature roll-to-roll sputtering as a viable alternative to ITO electrodes for the cost-effective production of large-area flexible touch screen panels (TSPs). By using a low resistivity metallic Cu interlayer and a patterned mesh structure, we obtained Cu2O/Cu/Cu2O multilayer mesh electrodes with a low sheet resistance of 15.1 Ohm/square and high optical transmittance of 89% as well as good mechanical flexibility. Outer/inner bending test results showed that the Cu2O/Cu/Cu2O mesh electrode had a mechanical flexibility superior to that of conventional ITO films. Using the diamond-patterned Cu2O/Cu/Cu2O multilayer mesh electrodes, we successfully demonstrated TSPS of the flexible film-film type and rigid glass-film-film type TSPs. The TSPs with Cu2O/Cu/Cu2O mesh electrode were used to perform zoom in/out functions and multi-touch writing, indicating that these electrodes are promising cost-efficient transparent electrodes to substitute for conventional ITO electrodes in large-area flexible TSPs.

Abstract

An aerobic, motile, Gram-negative, ice-active substance-producing, rod-shaped psychrophile, designated strain ArB 0140T, was isolated from seawater collected from near a glacier in Kongsfjorden, Svalbard Archipelago, Norway. Phylogenetic analysis using 16S rRNA gene sequences indicated that strain ArB 0140T showed a distinct phyletic line within the genus Moritella. Characteristic chemotaxonomic data [predominant isoprenoid quinone, Q8; major fatty acids, C14 : 0, C14 : 1, C16 : 0, C16 : 1 and C22 : 6 (docosahexaenoic acid; DHA)] also corroborated the affiliation of strain ArB 0140T to the genus Moritella. The maximal growth rate of the novel strain was observed at 9 degrees C, with a maximum temperature for growth of 18 degrees C. The genomic DNA G+C content was 46.9 mol%. Based on the data obtained from this polyphasic study, including DNA-DNA relatedness, physiological and biochemical tests and ice-controlling activity, strain ArB 0140T was found to be genetically and phenotypically different from other recognized species of the genus Moritella. Therefore strain ArB 0140T represents a novel species, for which the name Moritella dasanensis sp. nov. is proposed. The type strain is ArB 0140T (=KCTC 10814T=KCCM 42845T=JCM 14759T).
