OPERA-PU-TUD321d<br/>Radioactive substances and ionizing radiation are used in medicine, industry, agriculture, re- search, education and electricity production. This generates radioactive waste. In the Netherlands, this waste is collected, treated and stored by COVRA (Centrale Organisatie Voor Radioactief Afval). After interim storage for a...

This report studies clamping phenomena in placed revetments on the Dutch dikes. One of the reasons of placing stones is that the stability of the single stones increases. Pull–out tests on single stones show a strength up to 10 times the single stone weight. In present standardized design methods for placed revetments there is no significant...

In designing marine and coastal structures there always exists a considerable uncertainty, especially regarding the reliability of the data to be used. This is primarily due to the stochastic nature of sea waves - one of the most complex, volatile, pertinacious and uncomprehensible of nature's forces. Indeed, even if using all the available...

In general a safety factor or a conventional partial coefficient is used for the design of structures at sea. These methods are classified as Level I (deterministic) methods. However, such approaches do not allow the determination of the reliability (or the failure probability) of the design, and consequently it is neither possible to optimize,...

During the last few decades the believe that absolute security could be provided has been recognized to be mistaken in many branches of engineering. This happens as a consequence of the imperfect predictability of load intensity, structural characteristics and structural behavior, as well as a consequence of human gross errors during the design...

The project to protect Venice against periodic flooding appears to be a complex problem due to the city and surrounding environment that are extremely fragile, the presence of the port activity and the hazard of perturbation of the physical, chemical, biological equilibrium of the Venice lagoon. The mobile barriers are one of the components of a...

The safety analysis of marine systems is studied. One assumes that the required results of the hazard analysis are available. The identification of the appropriate performance function and the relevant reliability calculation are discussed in detail. The procedure is exemplified for some basic categories of marine systems.

This paper examines the possibilities of using Landsat Thematic Mapper images for updating land-use information on topographic maps. Information obtained from satellite images can be kept up-todate and a large number of classes can be distinguished. However, the quality of the information still leaves much to be desired, with a reliability of no...

This report describes the concept of reliability of nondestructive inspection (NDI) and reviews the different aspects involved. First, the probability of detection (POD) of flaws in flawed specimens is discussed. To provide a measure of confidence in an estimated POD, lower botind values of this probability at a given confidence level are...

The infrared Astronomical Satellite IRAS is equipped with an on-board computer system that takes care of vital satellite functions as attitude control, ground dialogue and execution of the observation programs. Therefore an important purpose of the IRAS system tests was the Verification and Validation of the on-board software. The test...

Modern commercial transport aircraft contain digital avionics systems for more and more safety critical functions. The reliability and safety of those new systems depend on the hardware reliability and on the reliability of the embedded software. In this report, an overview is given of available methods and techniques to develop reliable...

The present report describes how fatigue cracks were produced in 102 specimens. After cracking these specimens were inspected non-destructively by means of eddy currents, ultrasonics. X-rays and penetrants, and the indications were recorded. Successively the specimens were exposed to corrosion whereafter the inspections were repeated. Upon...
