Diagnostics of conductive adhesive joints and selected parts of adhesive assembly
Get PDFDizertační práce se zabývá novou tunelovou teorií vodivosti elektricky vodivých lepidel. Tato znalost je důležitá pro řízení optimálních podmínek procesu elektricky vodivé adhezní montáže. Součástí práce je I rozbor vlivů různých faktorů na kvalitu vodivých adhezních spojů. K tomuto rozboru bylo využito dvou metod: metody úplných faktorových experiment a metody Taguchiho ortogonálních oblastí. Taguchi-ho přístup je podstatně efektivnější v porovnání s úplnými faktorovými experimenty, ale nezahrnuje interakce. Cílem práce zde bylo ověřit, zda, a případně kdy, je možné nahradit úplné faktorové experiment Taguchi-ho metodou.This dissertation deals with a new tunnel theory of conductivity of electrically conductive adhesives. Such knowledge is necessary for control of optimum conditions of a joining process. The effect of different factors on quality of electrically conductive adhesive joints are examined using two methods: factorial experiments and Taguchi. The influence of selected technological factors and different climatic and electrical conditions on the resistance of conductive adhesive joints is studied using Taguchi approach and full factorial experiments. Taguchi approach is effective but provides less information as interactions cannot be calculated, while full factorial experiments gives information about effects of interactions on quality of adhesive joints

Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
