The article presents a method for optimizing driving strategies aimed at minimizing energy consumption while driving. The method was developed for the needs of an electric powered racing vehicle built for the purposes of the Shell Eco-marathon (SEM), the most famous and largest race of energy efficient vehicles. Model-based optimization was used to determine the driving strategy. The numerical model was elaborated in Simulink environment, which includes both the electric vehicle model and the environment, i.e., the race track as well as the vehicle environment and the atmospheric conditions. The vehicle model itself includes vehicle dynamic model, numerical model describing issues concerning resistance of rolling tire, resistance of the propulsion system, aerodynamic phenomena, model of the electric motor, and control system. For the purpose of identifying design and functional features of individual subassemblies and components, numerical and stand tests were carried out. The model itself was tested on the research tracks to tune the model and determine the calculation parameters. The evolutionary algorithms, which are available in the MATLAB Global Optimization Toolbox, were used for optimization. In the race conditions, the model was verified during SEM races in Rotterdam where the race vehicle scored the result consistent with the results of simulation calculations. In the following years, the experience gathered by the team gave us the vice Championship in the SEM 2016 in London.

Willingness To Cooperate

Victims play a central role in criminal case processing, but research suggests many victims do not report crimes to police or cooperate in a police investigation. This study extends the literature on victim cooperation by examining the effect of incident-level variables and neighborhood characteristics on victim cooperation in nonfatal shooting incidents. The sample includes 1,054 nonfatal shooting victims from two Midwestern cities. Results using binary logistic regression suggest that incident and victim characteristics are significantly associated with cooperation, but race conditions the effect of injury severity and motive on cooperation. The willingness to cooperate among Whites is contingent on injury severity while non-White victims do not become markedly more cooperative when confronted with serious injury. Race also moderates the relationship between crime motive and cooperation. This work demonstrates the need to incorporate nonfatal firearm violence into studies of victim cooperation and gun crime more broadly.

Steel Balls

The behaviour of individual ball to track contact areas is studied in close conformity oil lubricated conditions. Although primarily concerned with aero-engine operating conditions the results are expressed in dimension-less forms which permit use over a wide field of ball race geometries. An arbitrary boundary is established, based upon electrical conductance through the oil film, between running conditions which produce minimal wear damage and conditions which are probably unacceptable from this point of view. The major purpose of the paper is to focus attention on this criterion and to relate ball to track kinematic situations to it.
