Electronic Health Records (EHR) are data generated during routine clinical care. EHR offer researchers unprecedented phenotypic breadth and depth and have the potential to accelerate the pace of precision medicine at scale. A main EHR use-case is creating phenotyping algorithms to define disease status, onset and severity. Currently, no common machine-readable standard exists for defining phenotyping...
This article discusses the possibilities of the location of aircraft via active and passive radiolocation systems. The next part is dedicated to location recording of the aircraft, which uses the general type of Radiolocation Warning Receiver by triangulation method and PG method. Then we examine the analysis of the measured data with the purpose of determination of the location of source radiotechnical...
An increased level of safety in operation is one of the requirements prescribed by EU regulations for control trans-formers. This requirement is verified by a special test of the transformer resistance during its short-time overload. The paper provides an analysis of testing conditions and gives an example of the testing equipment construction.
Traditional methods and new method for measurement of low non-linearity of electronic components and circuits are described in this paper. Maintaining a linearity of components and circuits that are on principle linear is a measure of their quality. Passive intermodulation distortion (PIM) and non-linearity itself arises as a result of faults in production or component degradation and limits their...
Increasing requirements on data sharing in the domain of electrophysiology lead to proposing new terminologies and data models. A current trend is to describe data by ontologies and semantic web resources. However, classic technologies and models cannot be replaced in a short time. Due to this, dependencies between various data models should be explicitly described and properties, which the models...
This paper describes a circuit arrangement, design and construction of the power load composed of many pieces of thick film flanged resistors, which are serial-parallel connected so that the resulting combination showed the desired impedance-resistance, which may or may not be consistent with the resistance of individual components and, at the same time, it can be loaded with more power than a single...
This article describes a device for phase noise measurement using the phase lock technique. This allows the user to measure signals with level of the phase noise lower than −160 dBc/Hz. The effects of the measuring device on the measurement results are analyzed and examples phase noise measurements using PLL method, circuits for low-frequency signal processing and for power supplies with minimal own...
The EEG/ERP (Electroencephalography/Even-Related Potentials) Portal serves for storage and management of ERP experiments. The protocols describing these experiments are designed and implemented using various software applications and/or hardware devices. Some protocols are kept in XML files and stored in the EEG/ERP portal database as LOB (Large Object) data types. Since it is important for researchers...
This article deals with design and realization of control system for foodstuffs air — conditioned storing. System was developed with regard to minimal demand on energy consumption. It controls the operation of ventilators ensuring the exchange of air with the outside environment according to temperature of outside environment and temperature inside of stock room.
All electronic equipment where large S/N ratio is requested for the signal processing is very sensitive on disturbances coming from power supplies. This is especially true for high accuracy measurement equipment. Then simple solution is to feed such equipment from accumulators or batteries; nevertheless, this brings problems with their servicing. This contribution presents the results of study of...
Bio-impedance evaluation is one of the medicine diagnostic methods for the evaluation of tissue perfusion. The bioimpedance on the patient's body surface is evaluated by analogue HF-vector Z-meter. The Z signal is converted into a digital form and further digitally processed and filtered. Spurious disturbing signals distorting the bio-impedance signal are suppressed by adaptive FIR filter.
This contribution describes bridge symmetric crystal oscillator. A selective component of the oscillator is realized as Wheatstone bridge with two identical crystal resonators. An amplifier of this oscillator is realized as a symmetrical differential amplifier. Oscillator is especially solved with a view to achieve minimal phase noise of generated signal. Results are compared with common Gouriet-Clapp...
This paper describes a wire resistor with the resistance of several hundreds ohms, with a power dissipation up to several hundreds watts. In a high frequency band, it shows maximum frequency reflection coefficient values with respect to the nominal resistance value of about 0.1, and which reaches a third order IM distortion products close to −130dBc at the dissipation power.
