In order to reduce nitrogen oxides (NOx) and soot emissions while maintaining high thermal efficiency, more advanced combustion concepts have been developed over the years, such as Homogeneous Charge Compression Ignition (HCCI) and Partially Premixed Combustion (PPC), as possible combustion processes in commercial engines. Compared to HCCI, PPC has advantages of lower unburned hydrocarbon (UHC) an
Modern organizations face significant information security violations from inside the organizations to which they respond with various managerial techniques. It is widely believed in IS security literature that enforcing IS security policy compliance on employees through various means is the solution for security effectiveness. Nevertheless, this manuscript challenges that notion and advances a st
Increased research is being driven by the automotive industry facing challenges, requiring to comply with both current and future emissions legislation, and to lower the fuel consumption. The reason for this legislation is to restrict the harmful pollution which every year causes 3.3 million premature deaths worldwide [1]. One factor that causes this pollution is NOx emissions. NOx emission legisl
The extensive discussions of the relationship between the history of science and the philosophy of science in the mid-20th century provide a long history of grappling with the relevance of empirical research on the practices of science to the philosophical analysis of science. Further, those discussions also touched upon the issue of importing empirical methods into the philosophy of science throu
An intense octave-spanning supercontinuum with pulse energy of 160 μJ has been generated in an all-solid-state multiple-plate arrangement and successfully compressed to near-transform limited single-cycle duration of 2.8 fs.
In order to study the notion of habit as an instance of Thirdness in Peirce’s work, it is necessary to go back to the intuitions at the basis of Peirce’s categories, trying to spell out concretely, as I think this has not been done before, the meaning of the three categories. This involves entangling the notions of fallibilism and of the collaborative work of the community of scholars, which may n
Within the project LATERES COCTILES early fired bricks have been the objectof a multifaceted investigation. One aim has been to elucidate the mechanisms behind the diffusion of this innovation. An inventory of Hellenistic and early Roman fired bricks around the Mediterranean resulted in an archaeological database comprising 276 brick contexts. Network analysis was applied to these data using a two
Scrubbing is widely used in biomass gasification plants for tar removal. However, the cost of the scrubber liquid and its disposal once used can represent a non-negligible part of the plant operating cost. It is possible to lower this cost by regenerating and reusing the scrubber liquid by removing ash and heavy tars with the help of a centrifuge. Data from the two biomass gasification plants Hort
Optical spectroscopy, and in particular laser spectroscopy, has numerous applications in the assessment and probing in ecology, such as agricultural field and flying pest insect monitoring, as well as in the measurement of atmospheric pollutants. An overview of recent work by our group is given.
Yearly 3.3 million premature deaths occur worldwide due to air pollution and NOx pollution counts for nearly one seventh of those [1]. This makes exhaust after-treatment a very important research and has caused the permitted emission levels for NOx to decrease to very low levels, for EURO 6 only 0.4 g/kWh. Recently new legislation on ammonia slip with a limit of 10 ppm NH3 has been added [2], whic
A surprisingly dominant contribution of slow electrons is observed following NIR strong-field ionization of clusters. This is consistent with highly efficient intra-Rydberg correlated electronic decay processes, from which the emission of low-energy electrons is expected.
