Mācību platformas izglītības digitalizācijas kontekstā Latvijā

2018

Šobrīd, Latvijā notiek vairākas izglītības sistēmas reformas, un viena no tām, nepārprotami, skar arī izglītības digitalizācijas politiku. Pedagoģiskie spēki, skolas vadība un izglītības satura veidotāji nespēj pilnvērtīgi izmantot daudzpusīgo, digitālo mācīšanās risinājumu iespējas un kavē izglītības digitalizācijas procesa norisi, jo tehnoloģiju attīstības straujā daba ir grūti savienojama ar izglītības sistēmas pārmaiņu procesu kārtību. Nepieciešamība izvērtēt izglītības digitalizācijas pedagoģisko potenciālu un Latvijā izveidotā un pielāgotā digitālā mācību satura iespējas noteica Artas Rūdolfas maģistra darba tematu “Mācību platformas izglītības digitalizācijas kontekstā Latvijā”.

Determinants of performance drivers in online food delivery platforms: a dynamic performance management perspective

2022

PurposeThis study aims to demonstrate that the Dynamic Performance Management (DPM) framework, integrating performance management with system dynamics modelling, enables decision-makers to identify sustainable strategies in online food delivery platforms, thereby avoiding company failure.Design/methodology/approachThis study undertakes a multistep methodological approach. After the literature review, a retrospective case study approach was used. To build the DPM framework and the system dynamics simulation model, primary and secondary data were collected and analysed.FindingsThis study by adopting the DPM perspective highlights the critical role performance drivers play to assess the viabil…

Scalable and effective multi-level entangled photon states: a promising tool to boost quantum technologies

2021

Abstract Multi-level (qudit) entangled photon states are a key resource for both fundamental physics and advanced applied science, as they can significantly boost the capabilities of novel technologies such as quantum communications, cryptography, sensing, metrology, and computing. The benefits of using photons for advanced applications draw on their unique properties: photons can propagate over long distances while preserving state coherence, and they possess multiple degrees of freedom (such as time and frequency) that allow scalable access to higher dimensional state encoding, all while maintaining low platform footprint and complexity. In the context of out-of-lab use, photon generation…

Force-Time Characteristics and Running Velocity of Male Sprinters during the Acceleration Phase of Sprinting

1988

Abstract In an effort to investigate the force-time characteristics during the acceleration phase of the sprint start, eight male sprinters were used as subjects. Runs up to 3 m were analyzed from film, and force-time parameters were measured on a force platform. In a starting stance the reaction time of the group was .118 ± .016 s and the force production lasted .342 ± .022 s. The maximal resultant force at the moment of maximal horizontal force was 19.3 ± 2.2 N x kg1, and the direction of the force was 32 ± 7°. In the very last instant before leaving the blocks the velocity of the center of gravity was 3.46 ± .32 m x s−1. In the first contact after leaving the blocks there was a braking p…

Mechanical power and segmental contribution to force impulses in long jump take-off

1979

Changes in total mechanical work, its partitioning into different energy states, mechanical power, force-time characteristics, force impulses of body segments and mass center's pathway characteristics during long jump take-off were investigated on four national and six ordinary level athletes. Both cinematographic and force-platform techniques were used. The data showed that the national level jumpers had higher run-up and higher take-off (release) velocities in horizontal and vertical directions. In addition, they were able to utilize efficiently the elastic energy stored in the leg extensor muscles at take-off impact. This was seen in high support leg eccentric and concentric forces, whic…

The design and implementation of Neuma, a collaborative Digital Scores Library - Requirements, architecture, and models

2012

This paper presents the design and implementation of the Neuma platform, a digital library devoted to the preservation and dissemination of symbolic music content (scores). Neuma is open to musicologists, musicians, and music publishers. It consists of a repository dedicated to the storage of large collections of digital scores, where users/applications can upload their documents. It also proposes services to publish, annotate, query, transform, and analyze scores. The long-term goal of the project is to enable an open and collaborative space where musician communities will be able to share music in symbolic notation. The project is organized around the French IRPMF institute (BnF–CNRS) whi…

La tutela del contraente debole nella platform economy

2018

Negli ultimi anni si è affermato un nuovo modello di attività produttiva nel quale piattaforme digitali mettono in contatto gruppi interdipendenti di agenti economici per facilitare lo scambio di beni e l’erogazione di servizi. Dinanzi a questa trasformazione nell’organizzazione d’impresa, nel coordinamento del lavoro e nella struttura dei mercati, il diffuso appello a stabilire un “terreno di gioco neutrale” diviene la premessa per proporre la deregolamentazione di interi comparti economici valorizzando la capacità di autogoverno delle piattaforme. Mentre le reazioni a queste proposte sono confinate quasi esclusivamente alla questione del lavoro, è mancata finora un’analisi più generale de…

A platform-independent software for the design and analysis of windings of rotating electrical machines

2014

In this paper the Authors present a highly modular and platform-independent software, being based on the MATLAB® programming environment, which is proposed as a valuable aid in the design and analysis of the windings of rotating electrical machines. Unlike the major part of the commercial software, the cases of both symmetric and asymmetric (unbalanced) windings with any number of phases are here considered. The software can perform a considerable amount of calculations in order to determine automatically the optimal structure of the winding starting from its specifications. It is also able to draw the winding map and gives the results of calculation for the harmonic winding factors. The re…

Platform switching on wide-diameter external hex implants: a finite element analysis.

2012

Objectives: The objective of this work was to use finite element analysis to compare the effect of forces coming to bear on abutments 4.1 or 5.0 mm in diameter connected to a 5.0 mm implant (i.e. with or without platform swit - ching). Study design: A 3D CAD model of a 5 x 11.5 mm external hex implant was developed, complete with a connection screw and either of two abutments, one 4.1 and the other 5 mm in diameter, to assess the influence of two loading conditions, i.e. 200 N loaded either axially or off center on the top of the abutment. Results and conclusions: In the symmetrically loaded models, greater stresses were transmitted to the bone in the area below the neck of the implant in t…
