The Environmental and Economic Effects of European Emissions Trading

In 2005, the EU introduced an emissions trading system in order to pursue its Kyoto obligations. This instrument gives emitters the flexibility to undertake reduction measures in the most cost-efficient way and mobilizes market forces for the protection of the earth's climate. In this paper, we analyse the effects of emissions trading in Europe, with some special reference to the case of Germany. We look at the value of the flexibility gained by trading compared to fixed quotas. The analysis will be undertaken with a modified version of the GTAP-E model using the latest GTAP version 6 data base. It is based on the national allocation plans as submitted to and approved by the EU. We find that, if the NAP is combined with a regional emissions trading scheme, then Germany, Great Britain, and Czech Republic are the main sellers of emissions permits, while Belgium, Denmark, Finland, and Sweden are the main buyers. The welfare gains from regional emissions trading - for the trading sectors only - are largest for Belgium, Denmark, and Great Britain; smaller for Finland, Sweden, and smallest for Germany and other regions. When we take into account the economy-wide and terms of trade effects of emissions trading, however, the (negative) terms of trade effects can offset the (positive) allocative efficiency gains for the cases of the Netherland and Italy, while all other regions ended up with positive net welfare gains. All regions, however, experienced positive increases in real GDP as a result of regional emissions trading.

Improved Fault Diagnosis in Hydraulic Systems with Gated Convolutional Autoencoder and Partially Simulated Data

This paper examines the effectiveness of neural network algorithms for hydraulic system fault detection and a novel neural network architecture is suggested. The proposed gated convolutional autoencoder was trained on a simulated training set augmented with just 0.2% data from the real test bench, dramatically reducing the time needed to spend with the actual hardware to build a high-quality fault detection model. Our fault detection model was validated on a test bench and showed accuracy of more than 99% of correctly recognized hydraulic system states with a 10-s sampling window. This model can be also leveraged to examine the decision boundaries of the classifier in the two-dimensional embedding space.</jats:p

Influence of Laser Beam Wobbling Parameters on Microstructure and Properties of 316L Stainless Steel Multi Passed Repaired Parts

The results of experimental studies of repair of the supporting structure components made of 316L steel multi-pass laser cladding with filler wire are presented. The influence of the wobbling mode parameters, welding speed, and laser power on the formation of the deposited metal during multi-pass laser cladding with filler wire of 316L steel samples into a narrow slot groove, 6 mm deep and 3 mm wide, are shown. Non-destructive testing, metallographic studies, and mechanical tests of the deposited metal before and after heat treatment (2 h at 450 &deg;C) were carried out. Based on the results of experimental studies, the optimal modes of laser beam wobbling were selected (amplitude&mdash;1.3 mm, frequency&mdash;100 Hz) at which the formation of a bead of optimal dimensions (height&mdash;1672 &mu;m, width&mdash;3939 &mu;m, depth of penetration into the substrate&mdash;776 &mu;m) was ensured. A laser cladding technology with ESAB OK Autrode 316L filler wire has been developed, which has successfully passed the certification for conformity with the ISO 15614-11 standard. Studies of the chemical elements&rsquo; distribution before and after heat treatment showed that, after heat treatment along the grain boundaries, particles with a significantly higher Mo content (5.50%) were found in the sample, presumably precipitated phases. Microstructure studies and microhardness measurements showed that the upper part metal of the third pass, which has a lower microhardness (75% of base metal), higher ferrite content, and differently oriented dendritic austenite, significantly differs from the rest of the cladded metal
