The progressing urbanization leads to the growth of buildings within the cities and taking up new areas for investments. Uncontrolled urban sprawl entails a number of consequences resulting in the soil sealing of the areas which has been permeable so far. Cutting off deeper soil layers from gas exchange and access to water causes a reduction in biological activity and biodiversity. That is why EU...
One of the most recent methods for speech articulators assessment is the Electromagnetic articulography (EMA). By correlational and regressive analysis of signals from articulograph and video camera it becomes possible to determine relationships between motion of internal and external speech articulators. This is important from the point of view of the visual to articulatory speech inversion — which...
Electromagnetic articulography (EMA) is a novel method of speech articulators assessment. By correlating signals from articulograph and video camera one can determine dependencies between internal and external speech articulators. This in turn is important for visual to articulatory speech inversion — the method allowing to estimate inner articulators movement without using aticulograph. This paper...
In the paper a movements analysis of a basic articulators is presented. Pronunciation of selected polish affricates consonants has been studied in two ways: electromagnetic articulography (EMA) and high speed video camera. Both methods was compared in the case of lip's tip movement. Solution with a camera can be used for analysis of external articulators instead of onerous EMA. This kind of investigation...
Electromagnetic Articulography (EMA) is one of the methods of examining tongue movements. This technique is usually supported by audio recordings and may be supplemented by video data in order to analyze external articulator movements. In the research presented here, a new approach using a microphone array and synchronous video recordings is proposed and an examination of Polish nasal consonant is...
Performance of Silicon Photomultipliers (SiPM) [1] strongly depends on bias voltage and temperature. The key aspect in low light detection is precision and stability of SiPMs gain. These requirements can be met by delivering accurate bias and keeping temperature on constant level. It is not very demanding task in case of single SiPM. However, in applications consisting of thousands of SiPMs it is...
This paper presents the effect SOI detector's bias voltage has on current-voltage characteristics of different types of transistors (core transistors, io transistors, body floating, sourcetie, body-tie, low/normal/high threshold voltage). Methods of minimizing this effect were presented. Also, the I–V characteristic of transistors utilizing shielding layer (BPW - buried P Well) were measured and presented...
This paper presents the method for the compensation of the temperature fluctuations in the measurement system based on the Silicon Photomultipliers. The system was created by the authors of the paper. Temperature has very strong influence on the gain of the detectors. Because single photons are detected and the system is very sensitive, its parameters has to be steady during the measurements. Temperature...
This paper presents an efficient measurement system for a low-level light detection, emitted by fluorescent dye. The system setup and measuring method has been discussed. Silicon photomultiplier, which is called Multi Pixel Photon Counting developed by Hamamatsu, has been used as a light detector. Tests were made for fluorescein specimens in 1.5ml volume PMMA (Polymethyl Methacrylate) cuvettes positioned...
In the paper a measurement system for low intensity light is presented. This system has been adapted for fluorescence light measurement, generated by fluorescein solution with pH equal 8.1. The whole system is capable of measuring the fluorescence light intensity of the solution deposited in a transparent cuvette, and positioned in a specially prepared optical system. A new semiconductor device, called...
