Corruption manual for beginners: "Corruption techniques" in public procurement with examples from Hungary

This paper develops 30 novel quantitative indicators of grand corruption that operationalize 20 distinct techniques of corruption in the context of public procurement. Each indicator rests on a thorough qualitative understanding of rent extraction from public contracts by corrupt networks as evidenced by academic literature, interviews and media content analysis. Feasibility and usefulness of the proposed indicators are demonstrated using micro-level public procurement data from Hungary in 2009-2012. While the prime value of this broad set of indicators is the possibility of combining them into a robust composite indicator of high-level corruption, the high degree of detail also reveals that many regulatory interventions have succeeded in changing the form of corruption, but not its overall incidence

Estimation of Parameters for an Extremely Low Fuel Consumption Internal Combustion Engine-based Megameter-III Vehicle

Megameter-III is a special vehicle designed and constructed for international competitions by our team. A crucial part of the vehicle is the internal combustion engine, which ought to have extremely low fuel consumption. The experiences of previous competitions confirmed that it is necessary to develop a professional telemetry system, which allows tracking and logging online important parameters of the engine and the vehicle. In this paper, we discuss results for estimating of several parameters of the engine (angular velocity, angular acceleration, the Coulomb-Morin external friction torque and the damping constant). In our work, injector-pulses and inductive sensor’s signals were monitored
