Automated Mixed Traffic Vehicle (AMTV) technology and safety study

Technology and safety related to the implementation of an Automated Mixed Traffic Vehicle (AMTV) system are discussed. System concepts and technology status were reviewed and areas where further development is needed are identified. Failure and hazard modes were also analyzed and methods for prevention were suggested. The results presented are intended as a guide for further efforts in AMTV system design and technology development for both near term and long term applications. The AMTV systems discussed include a low speed system, and a hybrid system consisting of low speed sections and high speed sections operating in a semi-guideway. The safety analysis identified hazards that may arise in a properly functioning AMTV system, as well as hardware failure modes. Safety related failure modes were emphasized. A risk assessment was performed in order to create a priority order and significant hazards and failure modes were summarized. Corrective measures were proposed for each hazard

STEP-UP: Enabling low-cost IMU sensors to predict the type of dementia during everyday stair climbing

Posterior Cortical Atrophy is a rare but significant form of dementia which affects peoples’ visual ability before their memory. This is often misdiagnosed as an eyesight rather than brain sight problem. This paper aims to address the frequent, initial misdiagnosis of this disease as a vision problem through the use of an intelligent, cost-effective, wearable system, alongside diagnosis of the more typical Alzheimer’s Disease. We propose low-level features constructed from the IMU data gathered from 35 participants, while they performed a stair climbing and descending task in a real-world simulated environment. We demonstrate that with these features the machine learning models predict dementia with 87.02% accuracy. Furthermore, we investigate how system parameters, such as number of sensors, affect the prediction accuracy. This lays the groundwork for a simple clinical test to enable detection of dementia which can be carried out in the wild

ASSESSING TENNIS PLAYER INTERACTIONS WITH TENNIS COURTS

Different types of tennis injury have been associated with play on different court surfaces and current knowledge of tennis player and court interactions is limited. This paper provides a brief overview of tennis injury incidence, player movements and the biomechanics of slips. The discussion proposes a new direction for assessing tennis player-surface interactions and outlines current work. It is envisaged that current work will contribute to the understanding of tennis player-surface interactions and be of practical use in the future regulation of tennis courts

Lessons learned on the Skylab program

Lessons learned in the Skylab program and their application and adaptation to other space programs are summarized. Recommendations and action taken on particular problems are described. The use of Skylab recommendations to identify potential problems of future space programs is discussed

Advanced extravehicular activity systems requirements definition study. Phase 2: Extravehicular activity at a lunar base

The focus is on Extravehicular Activity (EVA) systems requirements definition for an advanced space mission: remote-from-main base EVA on the Moon. The lunar environment, biomedical considerations, appropriate hardware design criteria, hardware and interface requirements, and key technical issues for advanced lunar EVA were examined. Six remote EVA scenarios (three nominal operations and three contingency situations) were developed in considerable detail

Development of an inventory for consumer products containing nanomaterials : Final report

No RIVM report number ( 000201006 ) in publicationWhile various databases include consumer products containing nanomaterials, there is no consistent and reliable overview of these products. This study commissioned by DG Environment developed a methodology to identify consumer products containing nanomaterials, and tested it in populating a searchable database with a sample of 200 such products. In designing the database, attention was given to identifying and establishing the purpose and key stakeholders. A data model was developed for a structured record of data on individual products. The data model is directed to meeting user requirements in a searchable database. In addition, a methodology has been developed to address the validity of nano claims given the large degree of uncertainty about claim validity with respect to nanomaterials in consumer products. Using the data model, a sample database was populated with 200 products, which is searchable in various ways, and an output is made available in static HTML pages. This methodology and sample database could form the basis for further development of a database on nanomaterials in consumer products at the EU market. Recommendations for further action are included in the reportRIV
