چکیده
Pronalazak konstrukcije pravoga kuta odrazio se i u građevinarstvu i urbanizmu te limitiranju poljoprivrednih površina. Auktor opisuje nadgrobni spomenik rimskog agrimenzora iz Pompeja i zagonetni nalaz iz Pfiinza. Prihvaća rekonstrukciju pompejanskoga nalaza s tim da se jednonožni stalak radi stabilizacije instrumenta zamijeni tronolnim. Slobodno ovješene vizirne niti nategnute viškovima na vjetru su se nezavisno njihale ometajući mjernika pri viziranju. Ako se dvije suprotne niti dolje spoje i opterete s jednim viskom, postaju jedno tijelo. Auktor također ispravlja rekonstrukciju mjerne sprave nađene u Pflinzu. Na kraju je sažeto prikazana uporaba grome pri limitaciji agera rimskih kolonija.

The probability distribution of internal stresses in externally loaded 2 D dislocation systems Péter
Abstract. The distribution of internal shear stresses in a 2D dislocation system is investigated when external shear stress is applied. This problem serves as a natural continuation of the previous work of Csikor and Groma (Csikor F F and Groma I 2004 Phys. Rev. B 58 2969), where analytical result was given for the stress distribution function at zero applied stress. First, the internal stress ...

متن کاملGROMA Programming a Permanent Multichannel Sound Installation
In this paper I shall be addressing some of the more complex issues of developing the technical framework for the permanent urban sound installation GROMA, which incorporates environmental sounds from two partner cities of Cologne, Rotterdam and Liège, combined with ancient texts about urbanisation. This installation has been inaugurated in 2008 at the location of Europe’s largest underground p...
متن کاملOrigin of gradient terms in plasticity at different length scales
The origins of gradient terms in plasticity are discussed for three different cases related to atomic distance, dislocations, and finite grain size. 2002 Acta Materialia Inc. Published by Elsevier Science Ltd. All rights reserved.
متن کاملStochastic O(N ) algorithm for dislocation dynamics
A new computer simulation method based on stochastic integration of the Langevin equations of dislocation motion is proposed for the investigation of the dynamic properties of a system of parallel straight dislocations. The stochastic approach developed for weakly correlated dislocation systems allows for more than 106 dislocations in the simulation area. Relaxation of a system of 220 parallel ...
