In recent years, the Western European MARKAL-model has been extended witha materials system module covering the whole life cycle 'from cradle to grave'. The model including energy and materials is called MATTER 1.0. This document describes a further extension with an agricultural model, called MATTER 2.0. Ten agricultural crop types are...

The deployment of CCS in industry has a number of similar challenges as in the power industry. Unproven technology, increased energy use and the cost of innovative technology will hamper many projects. However, the heterogeneity of industrial processes means that certain early opportunities exist, whereby steams of near pure CO2 could be...

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...

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...

Molding compounds are key materials to deliver well packaged reliable IC’s for demanding applications, such as automotive electronics. With shrinking sizes of IC’s and the increased requirements with respect to loading conditions, application environment and lifetime, the reliability of the packaging becomes increasingly important. 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...

This paper introduces an approach to study the coupling structure between the design parameters and design objectives of a LED system-in-package (SiP) design concept [1]. The LED SiP is an integrated device that combines the LED chip with driver chips and potential other components in a single package, simplifying the design of lighting products...

Crash compatibility of a car fleet can be attained by simultaneous optimization of the car structures for all crash scenarios, with respect to self and partner protection. In this paper the approach is illustrated using detailed three-dimensional rigid body car models of a Neon Chrysler and a Ford Taurus. Only frontal crashes were considered for...

Light-emitting diodes (LEDs) are revolutionizing the illumination with energy savings and enhanced functionality. However, around 80% of the input power will be still transferred to heat. As the elevated temperature negatively affects the maximum light output, efficiency, quality, reliability and the lifetime of the SSL systems, thermal...

The reliability assessment aspect of the LED field is not fully developed. The lack of complete understanding is due, in part, to the newness of the field. SSL has not existed long enough to directly gauge the accuracy of the Lifetime Assessments being made. The approach of using simulation in qualification to Lifetime Assessment is one of the...

Intrinsic stresses in bondpads may lead to early failure of IC's. In order to determine the intrinsic stresses in semiconductor structures, a new procedure is set up. This procedure is a combined experimental/numerical approach which consists of the following steps: First, a conductive gold layer (20 nm thickness) is deposited on the power line...

Automotive electronics, solid-state-lighting, and solar cells need have to operate under harsh circumstances, either by the kind of environment they operate in, such as automotive electronics under the hood, or by the long durations of exposure. In both cases traditional lifetime assessment methods are failing: The accelaration factors, who are...

In the last few years Technical University of Delft, under leadership of Prof.dr.ir. Leo Kouwenhoven, has developed several successful concepts for quantum devices that are suitable for quantum computing and quantum communication. From a quantum research point of view we are still in a very fundamental state, several practical issues already...
