Surrogate Safety Measures (SSMs) are used to express road safety in terms of the safety risk in traffic conflicts. Typically, SSMs rely on assumptions regarding the future evolution of traffic participant trajectories to generate a measure of risk, restricting their applicability to scenarios where these assumptions are valid. In response to...

BACKGROUND: Decreased pelvic mobility and pelvic retroversion may result from spinal degeneration and lead to changes in the orientation of the acetabular implant after total hip arthroplasty (THA). While multiple patient and surgery-related factors contribute to THA dislocations, there is increasing evidence that sagittal spinopelvic...

Femoral component orientation plays a key role in implant stability and therefore the success rate of total hip arthroplasty. To date, this topic has been studied using various definitions and a variety of imaging modalities and protocols. The aim of this study is a proof of concept that a new algorithm can be used to describe the femoral...

Introduction: Dislocation remains a major complication in total hip arthroplasty (THA), in which femoral component orientation is considered a key parameter. New imaging modalities and definitions on femoral component orientation have been introduced, describing orientation in different planes. This study aims to systematically review the...

Background: Anterior and posterior pelvic tilt appears to play a role in total hip arthroplasty (THA) stability. When changing from the standing to the sitting position, the pelvis typically rotates posteriorly while the hips flex and this affects the femoro-acetabular positions. This case-control study compares changes in 3-D acetabular cup...

Objective: To determine the comparability among 10 radiographic anteversion methods for acetabular cup orientation in total hip arthroplasty (THA) found in the literature and the “gold” standard of assessing the anteversion with CT. Methods: This is a retrospective study that blindly compares 10 different conventional radiographic anteversion...

Background: Acetabular cup orientation plays a key role in implant stability and the success of total hip arthroplasty. To date, the orientation has been measured with different imaging modalities and definitions, leading to lack of consensus on optimal cup placement. A 3-dimensional (3D) concept involving a trigonometric description enables...

Innovation is vital to find new solutions to problems, increase quality, and improve profitability. Big open linked data (BOLD) is a fledgling and rapidly evolving field that creates new opportunities for innovation. However, none of the existing literature has yet considered the interrelationships between antecedents of innovation through...

Prior to being used in aviation, alternative fuels have to be tested thoroughly to ensure safe operation. At Delft University of Technology, a test programme was performed to evaluate the safety, performance and emissions of synthetic fuel blends. During test preparations, compatibility of the synthetic fuel with the aircraft, a Cessna Citation...

International jet fuel specifications permit up to 50% volume Fischer-Tropsch synthetic paraffinic kerosines (FT-SPKs), such as Gas-to-Liquids (GTL) Kerosine, in Jet A-1. Higher SPK-content fuels could, however, produce desirable fuels: lower density, higher SPK-content fuels may have benefits for Payload range (P/R) performance and their...

The radiative forcing caused by the emissions of jet aircraft is calculated using data from an aircraft performance model. Data from the performance model is needed to calculate the emissions of the aircraft. The sensitivity function and lifetime of the emitted gasses and particles are used to calculate the integrated radiative forcing of the...

The search for alternative fuels has lead to a number of possibilities. The most promising alternative fuels for the short term are drop-in fuels such as synthetic fuel and hydrotreated renewable jet. These fuels are similar to Jet A-1 but some differences are present. Synthetic fuels are produced using a process that results in a fuel without...

The present study is based on previous research on the poor body posture of surgeons and their experienced discomfort during surgical procedures. Since surgeons have head-bent and back-bent posture during open surgical procedures, a chest support is a viable supporting principle. This support is meant to reduce lower back pain by minimising...

This article describes a novel CVD process for TiN films developed in a 300 mm Vertical Furnace. We have solved Chlorine incorporation at low temperature inside the TiN layer while at the same time the batch process yields a 3 times higher throughput per dual reactor system compared to a single wafer system with 3 chambers.We show process...

TU Delft in the Netherlands is performing research into the effects of the use of synthetic kerosene in aircraft. The research program consists of both desk research and tests. In the desk research gas turbine simulations will be combined with payload range performance calculations to show engine effects and fuel consumption changes. Ground and...

Background: One of the main ergonomic problems during surgical procedures is the surgeon's awkward body posture, often accompanied by repetitive movements of the upper extremities, increased muscle activity, and prolonged static head and back postures. In addition, surgeons perform surgery so concentrated that they tend to neglect their posture....

The filling is reported of the air holes of an InP-based two-dimensional photonic crystal with solid polymer and withliquid crystal 5CB. The polymer filling is obtained by thermal polymerization of an infiltrated liquid monomer,trimethylolpropane triacrylate. The filling procedure for both the monomer and liquid crystal relies on the...

One-dimensional (1D) solid state systems can behave drastically different from their higher dimensional counterparts. Increased interactions can produce electronic and/or structural instabilities. In this respect, the following fundamental questions are important for a proper understanding of the properties of the ultimate 1D systems consisting...
