Presentation of the invention and the development of early watercraft using Arches platform

Magistrska naloga se loteva problema evidence in predstavitve nepremične kulturne dediščine s pomočjo odprtokodne platforme Arches. Dosedanji registri so v večini narejeni z različnimi zaprtimi orodji, zaradi česar je razvoj takšnih sistemov ustrezno dražji, predvsem pa so takšni sistemi zaradi svoje zaprtosti med seboj nepovezljivi. Platforma Arches naslavlja in rešuje velik del teh problemov. V okviru magistrske naloge sem prilagodil sistem evidenci in predstavitvi izuma in razvoja zgodnjih plovil (EarlyWatercraft.org) in z njim predstavil vse do sedaj evidentirane slovenske deblake. Sistem služi predvsem za predstavitev koncepta rešitve, ki ga je mogoče enostavno razširiti za uporabo na širšem področju (tudi po vsem svetu) ali pa ga prilagoditi uporabi tako ožje kot širše usmerjenim registrom. Izdelek je dobrodošla pridobitev za predstavitev tega področja z najnovejšimi tehnologijami in standardi, ki jih nudi sistem Arches.This master thesis addresses the challenges associated with the management and presentation of immovable cultural heritage using the Arches open source platform. The existing inventories are mostly proprietary, expensive and extremely difficult to interconnect. The Arches platform comes to rescue with all of that. In my thesis, Arches has been employed to present the invention and development of early watercraft, and includes a database of all known logboats in the territory of Slovenia. The EarlyWatercraft.org application demonstrates the ability of the Arches platform to be employed in a wide range of usesit can be applied for small-scale solutions but it can also be extended to accomodate large-scale (global) inventory requirements. The product presents early watercraft, which is a less known area of cultural heritage, to a wider audience using modern technologies and standards

Global Database of Early Watercraft: Beginnings, Development and Future Plans

The management and presentation of cultural heritage over a given region requires a dedicated database which can store all relevant information (location, text, photography, 3D models, animations etc.) and an intuitive way of accessing this information (searching via different criteria such as geo-location, time-frame, type of find, state of preservation, etc.). We decided to test a recently available open source platform, Arches 3.0, to construct a database of all known logboats and other early watercraft in the country of Slovenia: the Early Watercraft Database. The software platforms of existing inventories are mostly proprietary, expensive to maintain and difficult to interconnect and upgrade to new requirements. Existing database inventories are therefore difficult to combine and this makes the study of early watercraft finds on a global scale, independent of modern state boundaries, more difficult. By contrast, information stored in applications developed on the Arches platform can be easily merged. The Early Watercraft Database application demonstrates the ability of the Arches platform to be employed for a wide range of applications; it can be used for small-scale solutions but it can also be extended to accommodate large-scale (global) inventory requirements.

Correction of mould cavity geometry for warpage compensation

Warpage is one of the most challenging defects occurring in plastic injection moulded parts. Various approaches to overcome this issue have been proposed in the literature, but they all provide only partial solutions to the problem. This paper proposes a new method for the compensation and minimisation of warpage. The method is based on Mould Cavity (MC) correction. In contrast to other similar methods, here the MC correction is accomplished through a direct comparison of the local deviations of the warped part’s geometry to the desired geometry of the part. Modifying the MC shape accordingly yields parts with a lower shape discrepancy from the desired geometry compared to the nonadjusted shape. The key novelty of the paper is the development of software that iteratively adjusts the MC shape to minimise local deviations. In every iteration, the warped part is compared to the desired geometry in order to compute local deviations between both geometries. Computation is done first by determining the point normal vector of the warped geometry mesh and its piercing point through desired geometry mesh. Second, distance between the base point and the piercing point is calculated. After all local deviations are determined, the MC geometry is adjusted accordingly. Two case studies demonstrate the method’s capabilities. In the first case we present a curved thin-walled plate part. The maximum warpage value of 0.005 mm (0.7% of the initial maximum warpage) was reached after three iterations of MC geometry correction and remained stable afterwards. In the second case the method was tested on the box-shaped part. The maximum warpage dropped from initial 0.711 mm to 0.066 mm after three iterations

Helicobacter pylori treatment results in Slovenia in the period 2013-2015 as a part of European Registry on Helicobacter pylori Management

Helicobacter pylori (H. pylori) is the most common chronic bacterial infection in the world affecting over 50% of the world’s population. H. pylori is a grade I carcinogen, responsible for the development of 89 % of noncardia gastric cancers. In the present study we analyzed the data for H. pylori eradication treatments in Slovenia
