this paper presents an overview of model updating and particularly its application for updating of frame model. in this article a mathematical model of the frame was produced with finite element method. the frame was subjected to hammer modal testing. then the results of the modal testing were compared with those predicted with the model. this comparison revealed discrepancies between these two...

The objective of this study was to evaluate the long-term effects piling secondary forest residue (after 3 decades) on soil chemical properties, growth, and nutrition Pinus taeda weeds at three locations. After removal piling, areas were cultivated with P. (22 years), followed by eucalyptus (7 returned taeda. At 2 years age, tree height needle-nutrient levels ongoing from influenced outside zon...

Background: Piling, a behaviour where hens crowd together, is referred to as smothering if mortalities result. Smothering considerable concern for the egg industry, yet vastly understudied. Methods: During an outbreak of recurrent smothering, continuous video footage captured commercial, free-range flock over 35 days. We describe piling observed and potential associations with productivity heal...

The purpose of this study is to empirically reveal strategies of students' organization of learning-related digital materials within an online personal information archive. Research population included 518 students who utilized the personal Web space allocated to them on the university servers for archiving information items, and data describing their directory hierarchies. Several variables fo...

The operation and in particular the construction of offshore wind converters induce considerable underwater noise emissions. It is assumed that small whales and seals can be affected by noise from machines and vessels, piling and installation of the wind turbines. Piling, in particular using hydraulic hammers creates impulsive noise with considerable high energy levels. Currently, only little k...

In this paper we re-visit the Matsui’s linear cryptanalysis. The linear attack on the full round DES was the first attack that has been verified experimentally. Matsui extended one-round linear approximations to a linear mask of plaintext-ciphertext pairs by means of his piling-up lemma. The assumption of the lemma, the independence of the random variables in the round approximations, is hopefu...
