Tīmekļa tehnoloģijās balstītu kiosku pārvaldības risinājumi

2018

Palielinoties tehnoloģisko iespēju pieejamībai, pieaug interaktīvo stendu jeb kiosku pielietojums. Tie tiek izmantoti tirdzniecībā, saziņai un izklaides un izglītošanas nolūkiem. To programmatūras nodrošinājums bieži ir veidots, izmantojot tīmekļa tehnoloģiju risinājumus. Darba ietvaros pētīti kioska risinājumus ietekmējošie faktori, aktuāli pieejamie komerciālie un atvērtā koda risinājumi kioska programmatūras prasību nodrošināšanai, kā arī apskatīta tīmekļa tehnoloģijās balstītu lietojumprogrammatūras ietvaru atbilstība kioska programmatūras izstrādē un veikta lietotnes automatizētās atjaunināšanās sistēmas prototipa ieviešana.

Žestu atpazīšanas sistēmas realizācija Android lietotnē

2019

Darbā apskatīta ideja vienkāršot lietojumprogrammas palaišanu, bez meklēšanas ar žestu palīdzību. Darbā tiek apskatītas dažas žestu apatzīšanās metodes, īpašu uzmanību pievēršot dziļajiem neironu tīkliem. Lai žestu iemācītos no dažiem paraugiem ir realizēta datu papildināšana ar daudziem pārveidotiem žestu variantiem. Tika veikti eksperimenti labāko tīkla parametru atrašanai. Praktiski realizēta Android lietojumprogramma, kas ļauj atpazīt žestus, un spēj uz tālruņa, bez interneta lietošanas, apmācīt modeli uz jauniem, lietotāja definētiem žestiem. Darba mērķi ir: ● izveidot papildus mehānismu viedtālruņa vadībai; ● labāku neironu tīklu meklēšana apmācot atpazīt jaunus žestus.

A comparison of force-, velocity- and balanced training approach on force-velocity mechanical outputs and vertical jump height – of national level at…

2019

Master's thesis Sports Science ME517 - University of Agder 2019 INTRODUKSJON.Optimalisering av muskulær power-produksjon har blitt vurderttil å være en essensiell del av prestasjon i ulike idretter, men det foreligger lite litteratur på utøvere på nasjonalt nivå. På bakgrunn av dette,er målet med studien å sammenlikne hvilkettreningsprogram (kraftdominert, hastighetsdominert eller balansert) som er mest gunstig for å øke kraft-hastighetsparametre (F0, V0& Pmax)og vertikal hopphøyde. METODE.Trettifem mannlige elite-utøvere ble rekruttert og delt med stratifisert randomisering ut ifraderes kraft-hastighetsprofil inn i tre ulike treningsgrupper(kraftdominert, hastighetsdominert og balansert), …

Unipedal vertical jumping performance in soccer players

2011

Introduction: The muscular strength between the dominant and non-dominant legs of soccer players has been the centre of research that has highlighted contradictory results. Several researchers have reported symmetry between the dominant and non-dominant legs, whereas others suggest the existence of a significant asymmetry. Kicking and cutting skills in soccer are clearly unilateral, require asymmetrical motor patterns and can lead to the development of asymmetrical adaptations in the musculoskeletal function of the lower limbs (Fousekis et al., 2010). The purpose of this study was to examine the flight time [FT] and jump height [JH] during a vertical one-legged countermovement jump by domin…

Sequent depth ratio of B-jumps on smooth and rough beds

2013

A hydraulic B-jump has the toe section located on a positively sloping upstream channel and the roller end on a downstream horizontal channel. This paper analyses the B-jump on a rough bed, such as at the transition from a block ramp to the stilling basin. Laboratory measurements of the sequent depth were carried out using three different channel slopes for the rough bed and a single slope for the smooth bed. A solution useful for estimating the sequent depth ratio in a rectangular channel for different relative roughness and bed slope is proposed and positively tested by the present measurements. This solution can also be used to estimate the sequent depth ratio of classical hydraulic jump…

Might as well jump: Sound affects muscle activation in skateboarding

2014

The aim of the study is to reveal the role of sound in action anticipation and performance, and to test whether the level of precision in action planning and execution is related to the level of sensorimotor skills and experience that listeners possess about a specific action. Individuals ranging from 18 to 75 years of age - some of them without any skills in skateboarding and others experts in this sport - were compared in their ability to anticipate and simulate a skateboarding jump by listening to the sound it produces. Only skaters were able to modulate the forces underfoot and to apply muscle synergies that closely resembled the ones that a skater would use if actually jumping on a ska…

External Load Variables Affect Recovery Markers up to 72 h After Semiprofessional Football Matches.

2019

Background: Player tracking devices are commonly used to monitor external load from training and matches in team sports. Yet, how the derived external load variables relate to fatigue and recovery post-training or post-match is scarcely researched. The objective was, therefore, to investigate how external load variables affect recovery markers up to 72 h post-match. Methods: Semiprofessional players from six teams wore tracking devices during three experimental football matches. External load variables including individual playing duration, total distance, PlayerLoad™, high-intensity running, and high-intensity events were derived from the tracking devices, and blood samples and performance…

Concentric force enhancement during human movement

2001

In order to understand the possible mechanisms contributing to enhanced concentric performance in stretch-shortening cycle exercises in vivo the present study examined knee extension torque, electromyogram (EMG) activity and fascicle length of the vastus lateralis muscle in maximal and submaximal human movements. Maximal concentric knee extensions (120 degrees s(-1)) were done after pre-stretch and pre-isometric conditions by nine volunteers. During shortening at the knee angle of 115 degrees (180 degrees = extended) the knee extension torque was found to be greater in pre-stretch condition (272 vs. 248 N m, P < 0.05) although the torque level prior to shortening was smaller than in pre-iso…
