Kehä V – opastuksen toteutusmahdollisuuksia valtatiellä 25 ja kantatiellä 55

Tämä työ on osa vuonna 2007 alkanutta Kehä V –hanketta ja jatkoselvitys Kehä V:n opastuksen ja viitoituksen esiselvitykselle. Hankkeen taustalla vaikuttavat kaikki tien lähialueen kunnat sekä kauppakamarit. Myös kuntien elinkeinotoimet ja –yhtiöt ovat sitoutuneet hankkeeseen. Tässä selvityksessä on tutkittu tarkemmin Kehä V –viitoituksen toteutuksen mahdollisuuksia. Lähtökohtaisesti tarkoituksena oli tehdä tarkempia liittymäkuvia Kehä V -opasteista tarkempine kustannuksineen. Työn aikana jouduttiin kuitenkin myös uudelleen miettimään Kehä V –opastuksen muotoa ja luonnostelemaan sen teknistä toteutusta. Suunnittelun aikana työryhmä selvitti myös viranomaisilta Kehä V –opastuksen toteutumisnäkymiä. Tähän selvitykseen on koottu yhteen Kehä V:n viitoituksen lähtökohtia, toteutukseen liittyviä näkökohtia ja alustavaa kustannustietoa jatkotyöskentelyä varten.

Graduale (MS A.ö.II.55, Ilmajoen graduale)

A graduale (defect) from Ilmajoki. Written in three parts, part I (fols. 1-134) dating probably from the 1540's, part II (fols. 135-140) probably from the 1550's and part III (fols. 141-194) from the 1530's.

Real-time monitoring of laser scribing process utilizing high-speed camera

Currently, laser scribing is growing material processing method in the industry. Benefits of laser scribing technology are studied for example for improving an efficiency of solar cells. Due high-quality requirement of the fast scribing process, it is important to monitor the process in real time for detecting possible defects during the process. However, there is a lack of studies of laser scribing real time monitoring. Commonly used monitoring methods developed for other laser processes such a laser welding, are sufficient slow and existed applications cannot be implemented in fast laser scribing monitoring. The aim of this thesis is to find a method for laser scribing monitoring with a high-speed camera and evaluate reliability and performance of the developed monitoring system with experiments. The laser used in experiments is an IPG ytterbium pulsed fiber laser with 20 W maximum average power and Scan head optics used in the laser is Scanlab’s Hurryscan 14 II with an f100 tele-centric lens. The camera was connected to laser scanner using camera adapter to follow the laser process. A powerful fully programmable industrial computer was chosen for executing image processing and analysis. Algorithms for defect analysis, which are based on particle analysis, were developed using LabVIEW system design software. The performance of the algorithms was analyzed by analyzing a non-moving image from the scribing line with resolution 960x20 pixel. As a result, the maximum analysis speed was 560 frames per second. Reliability of the algorithm was evaluated by imaging scribing path with a variable number of defects 2000 mm/s when the laser was turned off and image analysis speed was 430 frames per second. The experiment was successful and as a result, the algorithms detected all defects from the scribing path. The final monitoring experiment was performed during a laser process. However, it was challenging to get active laser illumination work with the laser scanner due physical dimensions of the laser lens and the scanner. For reliable error detection, the illumination system is needed to be replaced.
