this study looks at the communication between users concerning health risks, with the aim of exploring their use of fora and assessing whether participants establish a niche with like-minded users during these exchanges. by integrating a corpus linguistic approach with content analysis and multiple studies on computer mediated health discourse, this study analyses the intense attention paid to ...
Objectives: Older adults show many difficulties of speech perception in noisy situations due to peripheral and central auditory impairments, and cognitive dysfunctions. One of the most common rehabilitative procedures for older adults with hearing loss is amplification. However, there is some evidence of dissatisfaction of amplification in older adults. Methods & Materials: We assessed cogni...
A measurement station dedicated for quantitative radiological characterisation of naturally occurring radionuclides in a metallurgical company and based on gamma-ray spectrometry was developed. The station is intended for performing quality control of final non-ferrous metal products and for radiological checks of incoming materials. A low-background point-contact HPGe-detector was used and the...
We developed a new method of determining site response and amplification for use in hazard analysis and station corrections. The method employs the conversion of P to S energy beneath a soft-rock station, which results in complex receiver functions that are frequency and amplitude dependent. At low frequencies ( 0.1 Hz), the ratio of vertical to radial energies for Pnl appear uniform across the...
We have improved the hardware and software of our autocompensating system for quantum key distribution by replacing bulk optical components at the end stations with fiber-optic equivalents and implementing software that synchronizes end-station activities, communicates basis choices, corrects errors, and performs privacy amplification over a local area network. The all-fiber-optic arrangement p...
This thesis report details the design and manufacture of HandWave, a wearable wireless Bluetooth skin conductance sensor, and dedicated housing. The HandWave collects Electrodermal Activity (EDA) data by measuring skin conductance over a pair of electrodes. The EDA data signal is used to infer the excitement level of the subject. The injection-molded housing is affixed to the wrist of the subje...
[1] We present a methodology to obtain frequencydependent relative site amplification factors using ambient seismic noise. We treat a seismic network or array as a forced damped harmonic oscillator system where each station responds to a forcing function obtained from frequencywavenumber beams of the ambient noise field. A network or array beam is necessary to estimate the forcing function. Tak...
In this study, soil characteristics were investigated using four well-located earthquakes recorded by six accelerometers located in North Cyprus. The amplification values obtained according to the soil features were mapped in accordance with different frequencies using horizontal to vertical spectral ratio method. The dominant period values of the units below the station locations were calculat...
