A Survey of the Reliability Methods Approach in Some Codes for Structural Design
Structural codes are documents which are subject to periodic revision and amendment. The main reason of this is due to developments from theoretical and experimental research. The rules and codes for the design of civil engineering structures which are prepared or which are under preparation by different regional and international organizations are under review. Similarities and differences in the approaches to the reliability — oriented concept of calculated safety verifications on the design stages prescribed in the codes (available to author) are presented in this paper.
NEW FRAMES OF ARCHAEOMETRICAL DESCRIPTION OF SPINDLE WHORLS: A CASE STUDY OF THE LATE ENEOLITHIC SPINDLE WHORLS FROM THE 1C SITE IN GRÓDEK, DISTRICT OF HRUBIESZÓW, POLAND
The essential role of yarn spinning in textile production is indisputable. In this context, spindle whorls, the basic spinning accessories that can be found in the archaeological record, are commonly discussed. Even though the importance of the technical specification of spindle whorls has been already recognized by some authors, their functional characteristics are usually limited to the basic parameters affecting their usage range (i.e., weight, diameter and height). And since the mass moment of inertia of spindle whorls is considered to be a salient index when discussing their technical variability, the descriptions are deficient. With this short study, we intend to implement further res…
