Optical Diagnostics of Hcci and Low-Temperature Diesel Using Simultaneous 2-D Plif of Oh and Formaldehyde

Simultaneous OH- and formaldehyde planar-LIF measurements have been performed in an optical engine using two laser sources working on 283 and 355 nm, respectively. The engine used for the measurements was a car diesel engine converted to single-cylinder operation and modified for optical access. The fuel, n-heptane, was injected by a direct injection common-rail system and the engine was also fitt

How can Asian Encounters help expose blind spots in sociological research?

How can Asian Encounters help expose blind spots in sociological research? During its 27th biannual conference, the Nordic Sociological Association (NSA) hosted the panel discussion Asian Encounters – Exposing or creating blind spots? Building on the theme of the conference – Exploring blind spots, the panel discussed the drawbacks and merits of studying Asia, as well as encounters between Asia

Electronic structure of [100]-oriented free-standing InAs and InP nanowires with square and rectangular cross sections

We report on a theoretical study of the electronic structure of free-standing InAs and InP nanowires grown along the [100] crystallographic direction, based on an atomistic tight-binding approach. The band structure and wave functions for nanowires with both square (nanowires) and rectangular (nanobelts) cross sections are calculated. A comparison is made between the calculations for InAs, InP, an

How does the brain respond to everyday objects?

Abstract in UndeterminedAn experiment is described where the participants were presented with pictures of four different objects and were also allowed to handle the objects while their brain activity was recorded by means of EEG. The objects were also evaluated by means of semantic scales. When the objects were visually displayed significant effects appeared in the posterior part of the brain, but

Importance of vertex corrections for obtaining correct selection rules in the theory of photoemission

It is shown that the commonly used approximation for the no-loss angle-resolved photocurrent from solids in general violates the optical selection rules if the final-state inverse low-energy electron diffraction orbital is taken to be damped. The violations occur in the velocity formula, which is inconsistent with the corresponding and commonly used acceleration formula in which the matrix element

Modelling tool life in the machining of strain-hardening material - Alloy 718

This publication presents a model that describes the lifetime of a tool when used for cutting work in strain-hardened material. The model is known as the Shortcut-Wear-Model (SWM) and can be com-pared with the established model based on Colding equation. The extent of this work has been limited to the turning of the nickel-based alloy 718 with fibre reinforced ceramic cutting tools. This model has
