Processing of Ceramic Fragments for Archeology
Šunka, Pavel ; Levek, Vladimír (referee) ; Šteffan, Pavel (advisor)
Presented thesis gives an insight into measuring the density and water absorption of ceramic fragments for archaeological purpose. It focuses on the design and construct of semi-automatic measuring device with a microchip PIC24FJ64GA004, storage of data on the SD card and subsequent processing by a spreadsheet.

New devices for diagnostics of historical structures
Hasníková, Hana ; Kloiber, Michal ; Zíma, Pavel
Two new devices developed at ITAM AS CR for non-destructive testing of materials, especially from historical structures, are presented below. So called microtube is a semi-automatic portable tool for water absorption measurements. The natural stones, mortars and other porous materials can be measured and it is very useful to assess the efficiency of various hydrophobic treatments used within the restoration also. The diagnostic device for in-situ assessment of timber enables direct determination of conventional compressive strength and modulus of deformation in arbitrary depth along timber profile. The semi-destructive method causes a very gentle damage on the structural members.
