In this paper we describe in detail our sensor fusion framework for augmented reality applications. We combine inertia sensors with a compass, DGPS and a camera to determine the position of the user’s head. We use two separate extended complementary Kalman filters for orientation and position. The orientation filter uses quaternions for stable representation of the orientation.

This paper presents a fuzzy control application in the unmanned driving field. Two electric cars have been conveniently instrumented in order to transform them in platforms for automatic driving experiments. The core of the guiding system is based essentially on an alliance of global navigation satellite systems, by now a centimetric DGPS, and on board speed and steering fuzzy controllers.

Digital platforms have become essential tools for the operational transformation of organizations over last few decades. Governments realized their advantages and are making progress in incorporating them into infrastructure, especially during COVID-19 era. This paper examines digital government (DGPs), value, characteristics. Previous research has identified a variety factors that affect e-gov...

We conduct a simulation study of Local Projection (LP) and Vector Autoregression (VAR) estimators structural impulse responses across thousands data generating processes, designed to mimic the properties universe U.S. macroeconomic data. Our analysis considers various identification schemes several variants LP VAR estimators. A clear bias-variance trade-off emerges: have lower bias than but sub...
