Foundation specialist contractors already have guidelines for carrying out bored pile work. However, in its implementation there are risks that could potentially lead to delays. This is because work not visible the ground. Therefore, existing need be developed based on risk. study aims identify and analyze potential will occur, as well responses taken form of preventive corrective actions, so d...

The contents of polycyclic aromatic hydrocarbons (PAH) in Frankfurtertype sausages were investigated in depency on hot smoking conditions (glow smoke), type of casing, back fat content and different types of wood chips. For the smoking experiments three different types of smoke densities and ventilator velocities, three types of casings, four different back fat contents (10%, 20%, 30%, and 39%)...

RWTH participated in the System Combination task of the Fifth Workshop on Statistical Machine Translation (WMT 2010). For 7 of the 8 language pairs, we combine 5 to 13 systems into a single consensus translation, using additional n-best reranking techniques in two of these language pairs. Depending on the language pair, improvements versus the best single system are in the range of +0.5 and +1....

The emphasis placed on bonding with the introduction of Acoustic Cement Bond Logs has led to a study of many of the variables influencing this property, as well as methods for improving bond at the casing-cement interface. Special cementing problems concerning gas storage wells and tubingless completion wells have also indicated the need for better pipe-cement bonding. This presentation stresse...

A unit that encloses a motor-compressor and a condenser of refrigerant fluid in a single hermetic casing is presented. After a description of the general advantages of the component compared with the traditional solution, as far as weight, size, cost and very low noise emission are concerned, experimental test results are presented. COP values in different working conditions show that a good en...

A critical phase of oil well completion involves positioning cement between the outer surface of a metal casing and the sides of the well. This task is done by injecting a specially formulated cement slurry down the center of the casing and up the sides of the bore hole. Designing these slurry systems is time consuming and expensive because of the variability of the conditions between wells and...

Although several studies have investigated the effect of degradation on the behavior of structures, investigations on collapse margin ratios are rare in the literature. In this study, the effect of strength and stiffness degradation on collapse capacity of steel moment frames is investigated. The aim is to determine margin of safety against collapse using a probabilistic approach. For this reas...

The answer may be yes. A discrete model of energy-conserved wavefunction collapse is proposed. It is shown that the model is consistent with existing experiments and our macroscopic experience.
