Hakukonemarkkinoinnin tehokkuus B2B ja B2C asiakkaille autonvuokrausalalla Suomessa

2012

Internetin nopea kasvu kaupankäynti-, viihde ja tietomediaksi on johtanut siihen, että yritysten on oltava internetissä. Internetin myötä perinteisesti markkinointiviestintää hallinneet markkinoinninkeinot ovat menettäneet asemaansa verkkomainonnan voimakkaan kasvun kustannuksella. Nopea kasvu on tuonut mukanaan haasteita; kuinka saada oma verkkosivusto kohdeyleisön tietoisuuteen oikealla hetkellä? Yksi vastaus haasteeseen ovat hakukoneet. Hakukonemarkkinointi voi olla oikein hyödynnettynä tehokas apuväline kohderyhmän ohjaamisessa yrityksen verkkosivuille. Hakukonemarkkinointi koostuu kahdesta tekniikasta, hakukonemainonnasta ja hakukoneoptimoinnista, joihin tässä tutkimuksessa perehdytään…

Dynamic Analysis of a 7 DOF Robot Using Fuzzy Logic for Inverse Kinematics Problem

2019

Abstract In this paper, a dynamic analysis for a redundant, serial robot, with seven degrees of freedom is presented. The dynamic model of the robot is based on importing a tri-dimensional CAD model of the robot into MATLAB®, Simulink®-Simscape™-SimMechanics™. One can import complete CAD assemblies, including all masses, inertias, joints, constraints, and tri-dimensional geometries, into the model. The first step for executing a dynamic analysis is to resolve the Inverse Kinematics (IK) problem for the redundant robot. Because this type of robot has seven degrees of freedom the IK resolution implies an infinite number of solutions. So, to be able to resolve the IK for this kind of robot a F…

Measurement and storage of a network of jacobians as a method for the visual positioning of a robot arm

1996

The goal of this paper is to describe a method to position a robot arm at any visible point of a given workspace without an explicit on line use of the analytical form of the transformations between real space and camera coordinates (camera calibration) or between cartesian and joint coordinates (direct or inverse kinematics of the robot arm). The formulation uses a discrete network of points distributed all over the workspace in which a procedure is given to measure certain Jacobian matrices which represent a good local linear approximation to the unknown compound transformation between camera and joint coordinates. This approach is inspired by the biological observation of the vestibulo-o…

Koherentas kustības uztveres izvērtēšanas metodes izstrāde

2021

Maģistra darbs ir uzrakstīts latviešu valodā. Satur 43 lapaspuses, 21 attēlu, 4 tabulas, 52 literatūras avotus. Darba mērķis: novērtēt faktoru (stimula fona kontrasta polaritāte, stimula ātrums, atkārtoti mērījumi, dalībnieks) ietekmi uz koherentas kustības uztveres slieksni. Rezultāti: Tika novērots, ka lielākai daļai dalībnieku, stimula fona polaritāte koherentas kustības uztveres slieksni neietekmē. Tomēr, atsevišķi dalībnieki uzrādīja būtiski zemāku koherences slieksni pie pozitīvas kontrasta polaritātes. Mainot stimula kustības ātrumu, atkārtotā mērījumā, pie stimula kustības ātruma 5 grādi/sekundē, koherentas kustības slieksnis samazinājās. Dalībnieki atšķirīgi reaģēja uz stimula fona…

Le silence des mots pour dire la barbarie terroriste : le pari esthétique et éthique de Jaime Rosales dans Tiro en la cabeza (2008)

2017

This article questions the aesthetic and ethical values of silence in Tiro en la cabeza (Bullet in the Head, 2008), a film without dialogue or music in which the Spanish director Jaime Rosales recreates the circumstances of an unplanned attack of Basque terrorist organization ETA.

Three-Dimensional Kinematics during the Take-Off Phase in Competitive Long Jumping

2013

The purpose of the present study was to identify the relationships among selected kinematic variables that affect the take-off phase and performance in elite jumpers. The jump distance was found to be related to: I) the athlete's approach speed before the instant of touch down; and ii) the exchange in spatial velocity components at take-off, which results in a gain in maximum vertical velocity of the centre of mass (CM), favoured by the use of an optimum touch-down angle of the take-off leg, an active landing of the foot at touch-down, and a motion of the take-off leg during the compression phase that helps to manage the loss of horizontal velocity. Nonetheless, the results show that an ad…
