he regional coastal evolution model Cascade was enhanced to better describe the transfer and storage of sediment. Focus was on the cross-shore exchange of material from the subaerial to the sub-aqueous portion of the beach and on shoal evolution at coastal inlets. Cross-shore material exchange now includes erosion due to wave impact and overwash, and barrier and dune build-up by wind. Cascade was

Bundle adjustment is a key component of almost any feature based 3D reconstruction system, used to compute accurate estimates of calibration parameters and structure and motion configurations. These problems tend to be very large, often involving thousands of variables. Thus, efficient optimization methods are crucial. The traditional Levenberg Marquardt algorithm with a direct sparse solver can be

Lattice Boltzmann method (LBM) is an alternative to conventional CFD to capture the detailed activities of the transport processes at microscale. Here LBM is used to model the hydrogen production by splitting water by incident sunlight over water covered Si-nanorods. The purpose of this study is, by a 3D microscale model, to investigate the transport and the formation of the hydrogen bubbles by el

A new method based on the mode matching technique and the finite element method (FEM) is presented. The method can handle a general thick frequency selective structure (FSS), that consists of an arbitraryn umber of aperture layers and dielectric layers. An aperture layer consists of a conducting plate with a periodic arrayof apertures. The order and the thickness of the layers can be arbitrary. The

Reading methods for software inspections are used for aiding reviewers to focus on special aspects in a software artefact. Many experiments have been conducted for checklist-based reading and scenario-based reading concluding that the focus is important for software reviewers. This paper describes and evaluates a reading technique called usage-based reading (UBR). UBR utilises prioritised use case

Research in innovation has resulted in much applicable knowledge in terms of tools, methods and processes. However, the challenge of allowing “space”, time and competence for innovation capability development is sparsely reported. The purpose of this research is to identify how organizational and behavioral factors affect product innovation capability and its development in organizations. The rese

TPA is known to cooperate with an activated Ras oncogene in the transformation of rodent fibroblasts, but the biochemical mechanisms responsible for this effect have not been established. In the present study we used c-fos promoter-luciferase constructs as reporters, in transient transfection assays, in NIH3T3 cells to assess the mechanism of this cooperation. We found a marked synergistic interac

The high-luminosity phase of LHC operations (HL-LHC), will feature a large increase in simultaneous proton-proton interactions per bunch crossing up to 200, compared with a typical leveling target of 64 in Run 3. Such an increase will create a very challenging environment in which to perform charged particle trajectory reconstruction, a task crucial for the success of the ATLAS physics program, an
