E-komercijas attīstība Eiropas Savienības digitālās ekonomikas ieviešanas stratēģijas kontekstā.

2016

Digitālā ekonomika Eiropas Savienībā šobrīd ir viena no galvenajām prioritātēm, ko ir noteikusi Eiropas Komisija ar izstrādāto Digitālo vienoto tirgus stratēģiju Eiropai visām Eiropas Savienības dalībvalstīm. Digitālai ekonomikai ir būtiska loma uzņēmējdarbības veicināšanā, kas ietver e-komerciju, IKT, jaunākās tehnoloģijas un inovācijas. Būtiski ir identificēt e-komercijas izmantošanas tendences un šķēršļus, kas pastāv Eiropas Savienības dalībvalstīs Tāpēc ir apskatīta digitālā ekonomika, e-komercija, nacionālās digitālās stratēģijas, Eiropas Savienības digitālais vienotais tirgus un tā stratēģiju, e-komercijas veidi, aktuālā statistika par digitālās ekonomikas attīstību un e-komercijas iz…

Industry 4.0: Advanced digital solutions implemented on a close power loop test bench

2021

Abstract The paradigm of Industry 4.0 allows to increase the efficiency and effectiveness of the production. Companies that will implement advanced solutions in production systems will increase their level of competitiveness and will be able reach high market shares. The present paper is focused on the development of advanced digital solutions to be implemented on a close power loop test bench designed to test high power transmissions for naval unit. In particular, the test configuration consists of a back-to-back connection between two identical mechanical reducers. Since the efficiency of these systems are very high, it is not necessary to use large electric motors, thus managing to conta…

A novel linear-non-linear digital control for DC/DC converters

2006

In this paper, a digitally controlled multi-module DC-DC converter with fast transient response, based on a linear-non-linear control is presented. The proposed digital control improves the stability of the system, cuts off the effects of limit-cycle and reduces the recovery time, by making the "effective" bandwidth of the system independent of the bandwidth of the linear control loop and limits, at the same time, output voltage variations. The novel digital control is AVP-compatible and halves the recovery time. Preliminary hardware tests on a single phase step-down converter are reported. The experimental results match simulation ones, obtained by modelling system with Matlab/Aldec mixed …

Detection of Ventricular Fibrillation Using the Image from Time-Frequency Representation and Combined Classifiers without Feature Extraction

2018

Due the fact that the required therapy to treat Ventricular Fibrillation (V F) is aggressive (electric shock), the lack of a proper detection and recovering therapy could cause serious injuries to the patient or trigger a ventricular fibrillation, or even death. This work describes the development of an automatic diagnostic system for the detection of the occurrence of V F in real time by means of the time-frequency representation (T F R) image of the ECG. The main novelties are the use of the T F R image as input for a classification process, as well as the use of combined classifiers. The feature extraction stage is eliminated and, together with the use of specialized binary classifiers, …

Laser Assisted Dirac Electron in a Magnetized Annulus

2021

We study the behaviour of a charge bound on a graphene annulus under the assumption that the particle can be treated as a massless Dirac electron. The eigenstates and relative energy are found in closed analytical form. Subsequently, we consider a large annulus with radius ρ∈[5000,10,000]a0 in the presence of a static magnetic field orthogonal to its plane and again the eigenstates and eigenenergies of the Dirac electron are found in both analytical and numerical form. The possibility of designing filiform currents by controlling the orbital angular momentum and the magnetic field is shown. The currents can be of interest in optoelectronic devices that are controlled by electromagnetic radi…

Practical procedure for verification of compliance of digital mobile radio base stations to limitations of exposure of the general public to electrom…

2002

In the last few years, society has witnessed the installation of an ever increasing number of radio base stations as a necessity for handling new capabilities and services to the large number of users. This rapid development of wireless networks, however, has induced a marked mistrustful attitude in people, who fear possible biological effects of electromagnetic emissions from mobile communications base stations. While there are guidelines on the limitation of human exposure to electromagnetic fields (emf ), there is no harmonised standard measurement procedure to evaluate compliance with the limits on exposure in the vicinity of a base station. The measurement procedure has to be practical…

Novel Method for the Direct Measurement of the τ Lepton Dipole Moments

2019

A novel method for the direct measurement of the elusive magnetic and electric dipole moments of the tau lepton is presented. The experimental approach relies on the production of tau+ leptons from Ds+ -> tau+ nu_tau decays, originated in fixed-target collisions at the LHC. A sample of polarized tau+ leptons is kinematically selected and subsequently channeled in a bent crystal. The magnetic and electric dipole moments of the tau+ lepton are measured by determining the rotation of the spin-polarization vector induced by the intense electromagnetic field between crystal atomic planes. The experimental technique is discussed along with the expected sensitivities.
