Abstract In the study of new solutions for motorcycle passive safety, FE models of full-scale crash tests play a strategic role. The most important issue in the development process of FE models is their reliability to reproduce real crash tests. To help the engineering in the validation phase, a sensitivity analysis of a FE model for motorcycle-car crash tests is carried-out. The aim of this study is to investigate the model response subjected to variations of specific input parameters. The DOE is performed generating a list of simulations (each one composed by a unique combination of 8 parameters) through Latin Hypercube Sampling. The outputs monitored are the Head Injury Criterion (HIC) and Neck Injury Criteria (Nij). The analysis of the results is performed using scatter plots and linear regression curves to identify the parameters that have major impact on the outputs and to assess the type of dependency (linear or non-linear).
Abstract Powered Two-Wheelers (PTW) control is more complex than any other motorized vehicle control, in particular during emergency events, such as panic braking or last second swerving. For standard PTW, a common cause of accident in these situations is the loss of stability due to braking maneuvers. It is worth noting that for PTW the loss of stability means a high probability of fall, especially while cornering. Accordingly, the aim of this study is to propose a fall detection algorithm for PTW performing maneuvers leading to potential instability. The algorithm is composed of a number of parameters, named RISKi, able to detect potential fall events, critical for PTW safety. This fall detection methodology was developed to alert an advanced riding assistance system in order to produce proper counteractions against the imminent fall.
Abstract ISO 26262 (Road vehicles - Functional safety), a functional safety standard for motor vehicles, was published in November 2011. In this standard, hazardous events associated with each item constituting a safety-related system are assessed according to three criteria, namely, Severity, Exposure, and Controllability, thereby determining ASILs (Automotive Safety Integrity Levels) representing safety levels for motor vehicles. Although motorcycles are not included in the scope of application of the current edition of ISO 26262, it is expected that motorcycles will be included in the next revision. However, it is not appropriate to directly apply ASILs to motorcycles. In the first place, the situation of usage in practice presumably differs between motorcycles and motor vehicles. Accordingly, in this research, we attempted to newly define Motorcycle Safety Integrity Levels (MSILs).

Solid chemical oxygen supplies of interest to aircraft operations are 'chlorate candles' and potassium superoxide (KO 2 ). Chlorate candles are used in passenger oxygen supply units and other emergency oxygen systems, such as submarines and escape devices. Potassium superoxide is not used in aircraft operations but is used in closed-cycle breathing apparatus. Characteristics and applications of both are discussed, with emphasis on chlorate candles.
