Marine seismic exploration uses air guns or air gun arrays to generate high energy, short duration acoustic pulses deep into the ocean floor but some of the seismic/acoustic energy remains in the water column and can propagate to considerably distances. This may cause disturbance to marine life and...
This paper presents an efficient way to compute second-order gradients by using the adjoint method for PDE-constrained optimization. The gradient thus obtained will then be used in an optimization algorithm. We propose a conjugate gradient combined with the trust-region method, which may have a...
In the secondary phase of oil recovery, water flooding is the most common way to sweep remaining oil in the reservoirs. The process can be regarded as a nonlinear optimization problem. This paper focuses on how to handle state constraints in an adjoint optimization framework for such systems. The...
...3D packaging and heterogeneous integration has revealed new opportunities with regard to where instrumentation can be applied. Extreme miniaturization of systems makes it possible to include sensors and electronics in regions where this was not possible earlier due to size or weight limitations...
Small and medium-sized enterprises are crucial to value creation in the European economy. The SMEs need continuous improvement initiatives to stay competitive. However, SMEs are less likely to implement lean practices compared to larger companies. Limited research exists on the factors that are...
The design, fabrication, and measurement results for a diaphragm-based single crystal silicon sensor element of size 820 µm × 820 µm × 500 µm are presented. The sensor element is designed for in vivo applications with respect to size and measurement range. Moreover, it is optimized for long-time...
Smartphones with third-party applications have become very popular. Recently, they have received attention for quietly monitoring and transferring personal information without the users’ knowledge. The objective of this work is to help users to protect their privacy by increasing their consciousness...
The main objective of the REMICS project is to specify, develop and evaluate a tool-supported modeldriven methodology for migrating legacy applications to interoperable service cloud platforms. The migration process consists of understanding the legacy system in terms of its architecture and...
... The objective of this paper is to further exploit and demonstrate the potential benefits of a V-min diagram based analysis, using a fifteen component feed mixture as base case. Detailed explanations are given on how to interpret properly a V-min diagram and use it for DWC assessment. Emphasis is on...
