In this study the consistency between MAX-DOAS measurements and radiative transfer simulations of the atmospheric O 4 absorption is investigated on 2 mainly cloud-free days during the MAD-CAT campaign in Mainz, Germany, in summer 2013. In recent years several studies indicated that measurements and radiative transfer simulations of the...

This paper presents a test case for coupling two physical aspects of an LED, optical and thermal, using specific simulation models coupled through an open source platform for distributed multi-physics modelling. The glue code for coupling is written with Python programming language including routines to interface specific simulation models. This...

We have developed a multi-scale model, consisting of an atomistic model in LAMMPS of an InSb nanowire, and a continuum model in COMSOL of a socalled Majorana research device, to study the effects of thermo-mechanical deformations during the cool down from room temperature to the operating temperature of about 50 mK. For the simulation of the...

In a highly competitive and demanding microelectronics market, reliable non-destructive methods for quality control and failure analysis of electronic components are highly demanded. Any robust non-destructive method should be capable of dealing with the complexity of miniaturized assemblies such as chip-scale packages and 3D IC stacks. Scanning...

The drive of increased electrical currents to achieve high luminous output for phosphor-converted white light-emitting diodes (PW-LED) has led to a series of thermal problems. The light performance of PW-LED is affected by the heat generated by the two major sources in a package/module: chip(s) and phosphors. In this work, spectral shift and...

Solid State Lighting (SSL) systems, powered by light-emitting diodes (LEDs), are revolutionizing the lighting industry with energy saving and enhanced performance compared to traditional light sources. However, around 70%-80% of the electric power will still be transferred to heat. As the elevated temperature negatively affects the maximum...

High Power Light Emitting Diode (HP LED) is one of the promising candidates for future lighting systems with efficient energy consumption. However, around 70% of the input power will be still transferred to heat. Recently, to obtain more light output, the increased electrical currents consequently cause more significant heat. To solve the...

The introduction of new materials or technologies can have an enormous impact on the Time to Market (TTM) of new products. Preferably, the performance of new materials or technologies is known before these are designed into a product. This paper presents a reliability assessment approach which has been developed with the aim to reduce the so...

The diode forward voltage method with pulsed currents was widely used for monitoring junction temperature (Tj of light-emitting diodes (LEDs). However, a thermal transient effect (TTE) was observed by the pulsed currents and consequent errors were introduced. Thermoelectric physics was conducted to explain this phenomena and a group of...
