In this paper, after analysing deformations of loading ball-bearing it is able to investigate vibrations of rotor-bearing system as the system with non-linear and periodically varying stiffness.The modelling of the systems is depent on properties of the shaft (rigid or flexible) and on measurement techniques for system vibrations (by eddy current I
A wide range of commonly abused drugs have effects on the noradrenergic neurotransmitter system, including alterations during acute intoxication and chronic use of these drugs.It is not established, however, that individual differences in noradrenergic signaling, which may be present prior to use of drugs, predispose certain persons to substance ab
This paper focuses on the classification of seven locomotion modes (sitting, standing, level ground walking, ramp ascent Dolls Pram and descent, stair ascent and descent), the transitions among these modes, and the gait phases within each mode, by only using data in the frequency domain from one or two inertial measurement units.Different deep neur
The rental of houses is a common economic activity.However, there are many inconveniences that arise when renting a property.The lack of trust between the landlord and the tenant due to fraud or squatters makes it necessary to involve third parties to minimize risk.A blockchain (such as Ethereum) provides an ideal solution to act as a low-cost inte
Hereditary epidermolysis bullosa is a big group of hereditary diseases with the main manifestations in the form of blisters on the skin and mucous coat after slight mechanical injuries.It is not always possible to diagnose this disease based on the clinical picture.The article discusses current laboratory diagnostics methods for hereditary epidermo
