Climate change is perhaps the most pressing and urgent environmental issue facing the world today. However our ability to predict and quantify the consequences of this change is severely limited by the paucity of in situ oceanographic measurements. Marine animals equipped with sophisticated oceanographic data loggers to study their behavior offer one solution to this problem because marine anim...

The globally increasing prevalence of childhood obesity is one of the most serious public health challenges of the twenty-first century. Due to the need for multi-professional therapies that require a high amount of personnel and financial resources, IT-supported interventions promise help. So far, meta-studies show their limited impact on health outcomes. This work presents therefore a design ...

Through the use of multiple-input/single-output (MISO) modeling, the propagation paths of sound within a reciprocating refrigeration compressor have been investigated and ranked. By investigating the nature of sound propagation within reciprocating compressors. it is hoped that strategies for compressor sound reduction can effectively be formulated . From experimental data of compressor far-fie...

We has been conducted the lightning observation with four type sensors at the International Space Station (ISS). One of the sensors is very high frequency interferometer: VITF. The objective of the VITF is to locate the radiation source of received signals with two very high frequency interferometer (VHF) sensors attached on the ISS. Lightning and sprite imager: LSI is also one of the optical s...

Numbered bee tags, developed for marking honey bees (Apis mellifera Linnaeus), are glued to the mesosoma of many bees to uniquely identify them. We recorded whether or not bees sonicated to collect pollen after being marked, and we compared the sonication frequency, sonication length, and wing beat frequency of Bombus (Pyrobombus) impatiens Cresson that were tagged with bee tags vs. marked with...

This paper describes the finite element modelling of air coupled ultrasonic using multiphysics approach. In the model, the two different physics domains were coupled to each other at the interface by using proper boundary conditions for each domain. The simulation result shows that, ultrasonic waves generated in plate structure are leaked to the air medium by creating the pressure wave. The tim...

We present a new technique for granular sampling using a pulsecoupled network of spiking artificial neurons to generate grain events. The system plays randomly selected sound grains from a given sound sample when any one of a weakly coupled network of up to 1000 neurons fires. The network can exhibit loosely correlated temporal solutions and also collective synchronised behaviour. This leads to...

Existing 3D ultrasound systems are based on mechanically moving 1D arrays for data collection and post-processing of data to achieve 3D images. To be able to both collect and process 3D data in real-time, a scaling of the ultrasound system from 1D to 2D arrays is necessary. A typical 2D-system uses 1D arrays with about 100 receive and transmit channels. Scaling of this system to get a 3Dsystem ...

This paper describes a prototype system for the objective assessment of voice quality in patients recovering from various stages of laryngeal cancer. A large database of male subjects steadily phonating the vowel /i/ was used in the study, and the quality of their voices were independently assessed by a speech and language therapist (SALT) according to their 7-point ranking of subjective voice ...

Key changes are common in Western classical music. The precise segmentation of a music piece at instances where key changes occur allows for further analysis, like self-similarity analysis, chord recognition, and several other techniques that mainly pertain to the characterization of music content. This article examines the automatic segmentation of audio data into parts composed in different k...
