Acoustic manipulation of sound with soft material-based actuators
No full textThis thesis describes a unique parabolic acoustic manipulator with an inflatable structure, which has high gain and directivity. We created a morphable elastomeric reflecting surface with a diameter of 14 cm (6 in). Applying vacuum deforms the device into a concave structure, which provides directional amplification of incoming acoustic waves. In addition, the author characterized the impedance of the soft material employed in the acoustic reflector, Ecoflex 00-10, in an impedance tube. Ecoflex 00-10 has a measured reflection coefficient of approximately 0.9 at frequencies ranging from 500 Hz to 5000 Hz. This new characterization suggests this class of silicone-based elastomers is capable of advanced morphable devices to manipulate sound. Simulations also demonstrate that the soft reflecting surface is capable of transformation into a set of desired parabolic shapes between an initial planar geometry (neutral position) and a configuration with maximum curvature. With an applied vacuum, the membrane reaches its maximum deformation limited by the aluminum housing. At this stage of actuation, experimental results show the deformed membrane has similar gain and directionality (polar response) as rigid parabolic reflectors. This type of system might find future uses for adjustable parabolic microphones and long-range communication devices.M.S.Includes bibliographical referencesby Yanjun Wan
Numerical simulations of laser wakefield acceleration using ionization-induced injection
No full textPráca sa zaoberá štúdiom laserového urýchľovania s ionizačnou injektážov elektrónov do brázdovej vlny pomocou particlein-cell kódu EPOCH. Simuláciami rôznych schém pre LWFA používajúc jeden resp. dva laserové zväzky a rôzne hustotné profily sme sa snažili získať vysoko-kvalitný elektrónový zväzok s malým energetickým rozptylom a nízkou emitanciou. Výsledky simulácií ukazujú, že elektrónový zväzok s relatívne dobrými parametrami (energetický rozptyl (FWHM) 23% a priečna emitancia - 2.55 ?m) je možné dosiahnuť pomocou dvoch laserových zväzkov s rôznymi vlnovými dľžkami pohybujúcich sa kolineárne. Na základe výsledkov zo simulácií sme navrhli a preskúmali vhodné parametre pre experiment na femtosekundovom laser v laboratóriu PALS. Navrhnuté jedno laserové sch´ema umožňuje urýchlenie elektrónov s energetickým píkom v okolí 30 MeV s energetickým rozptylom (FWHM) 32% a priečnou emitanciou 13, 22 ?m.Electron acceleration driven by laser wakefield and ionization-induced injection mechanism is studied in detail using the particle-in-cell code EPOCH. Different laser-plasma schemes using one or two laser pulses and different density profiles are examined with the aim to acquire highquality electron beam with small energy spread and low emittance. Simulation results show that relatively good electron beam quality can be reached (energy spread (FWHM) 23% and transverse emittance of 2.55 ?m) through two collinear propagating laser pulses with different wavelengths. On the ground of achieved simulation results we have proposed and analyzed suitable laser-plasma parameters for experimental setup for PALS laboratory experiment. Recommended single laser scheme allows acceleration of electrons with the maximal energy peak at around 30 MeV, energy spread of (FWHM) 32% and transverse beam emittance 13.22 ?m
AudioEar: Single-View Ear Reconstruction for Personalized Spatial Audio
No full textAbstract
We introduce AudioEar3D, a high-quality 3D ear dataset consisting of 112 point cloud ear scans with RGB images, to benchmark the ear reconstruction task. We further collect a 2D ear dataset composed of 2,000 images, each one with manual annotation of occlusion and 55 landmarks, named AudioEar2D. To our knowledge, both datasets have the largest scale and best quality of their kinds for public use.

Postgraduate Student, College of Tourism and Service Management, Nankai University. Her research interests are meteorological tourism, consumer behavior and tourism destination marketing.While the uncertainty is increasingly becoming a challenge in the supply of meteorological landscape for destinations, little is known about the emotional experiences and behavioural tendencies of visitors triggered by this uncertainty under landscape viewing. Grounded upon cognitive appraisal theory, this study conducted in-depth interviews with 31 visitors who had experience of seeing the meteorological landscape to solicit their perceptions and appraisals of uncertainty. Results revealed that the uncertainty influenced visitors’ cognitive appraisal process, including cognitive appraisal, emotional experiences, coping strategies, and behavioural tendency in the future. Specifically, five positive and four negative emotions, and two coping strategies were identified. In addition, four types of revisit intention were also discussed and summarised. Interestingly, this study found that positive emotions didn’t always trigger positive behavioural tendencies, while negative emotions may also contribute positively to behavioural tendencies. Theoretical and practical implications for destination management are also offered
Poinsettia and Easter Lily Growth and Development Responses to Root Substrate Containing Biochar
No full textGreenhouse production of Poinsettia (Euphorbia pulcherrima) and Easter lily (Lilium longiflorum) mainly uses peat-based root substrates. The decrease of peatland has increased the need for alternative root substrate components in the horticulture industry. Biochar, a byproduct of bio-energy production, has the potential to be an alternative root substrate component to reduce the use of peatmoss in greenhouse production. The objectives of the present studies were to determine the effects of different percentages of biochar and fertigation regimes on the growth and development of ���Prestige Red��� poinsettia and Easter lily ���Nellie White��� in greenhouse production.
Two experiments were conducted to evaluate different percentages of one type of biochar added to a commercial peat-based root substrate for poinsettia and Easter lily greenhouse production. In experiment one, rooted poinsettia cuttings were potted in one of the six root substrates mixes including Sunshine Mix #1 replaced by 0%, 20%, 40%, 60%, 80%, or 100% biochar (by volume) and irrigated under four fertigation regimes (100 to 200 mg���L-1 N, 200 to 300 mg���L^-1 N, 300 to 400 mg���L^-1 N, or 400 to 500 mg���L^-1 N). Root rot and red bract necrosis were only observed in the highest fertigation regime (400-500 mg���L^-1 N) combined with the highest biochar percentage (100%). At 100 to 400 mg���L^-1 N fertilization rate, up to 80% of the commercial peat-based root substrate could be replaced by biochar without a significant change in poinsettia growth and quality.
In experiment two, Easter lily bulbs were potted in one of the five root substrates mixes (Sunshine Mix #1 amended with 0%, 20%, 40%, 60%, and 80% biochar) and irrigated under four fertigation regimes (constant liquid feed at 200 mg���L^-1 N or 300 mg���L^-1 N, and fertilization at every third watering with 200 mg���L^-1 N or 300 mg���L^-1 N). Neither fertigation regimes nor biochar percentages significantly affected the Easter lily growth and development. Under the four fertigation regimes used in this experiment, up to 80% peat-based root substrate could be replaced by biochar without a significant difference on the growth and development of Easter lily
