Electrostatic field theory and circuit analysis in the design of coalescers with pulsed dc voltage

2009

This paper presents a mathematical analysis of the electric field and interfacial free charge experienced by the emulsion in an electrostatic coalescer that is subjected to a pulsed dc voltage. Previous work in this area is re-assessed, but the analysis is expanded. A novel static analysis of the system is presented, giving valuable physical insight. It becomes obvious that there must be a limited range of frequencies that are effective in a pulsed dc scheme. Thereafter, analytical expressions for the steady-state solution, where both the switching frequency and duty ratio (or mark space ratio) can be varied, are presented for the first time. These expressions are used to derive voltage and…

Ytterbium-doped fibers for high-power fiber lasers

2021

Ytterbium (Yb) doped optical fibers are widely used in high-power applications and ultrafast lasing since they show adequate power-handling capability and provide desirable beam quality. Yb-doped fibers with large core area can support high power but often act as a multimode fiber and compromise the output beam quality. Hence, it is important to attain a proper balance between the power-handling capability and the beam quality. Yb-doped fibers as a gain medium in pulsed fiber laser systems are prone to nonlinear optical effects due to the presence of high peak power in the ultrashort pulses. Nonlinearity such as self phase modulation (SPM) affects the width and the shape of the pulse, both …

Religious Engagement and the Migration Issue: Towards Reconciling Political and Moral Duty

2020

The increasingly acknowledged post-secular perspective has resulted in the emergence of some new approaches theorizing this phenomenon. One such approach has been the concept of religious engagement, which calls for the redefinition of the perception of religious non-state actors towards including them as important partners in the process of identifying and realizing political goals. According to this view, due to the multidimensional role played by religious communities and non-state religious actors, they need to be recognized as pivotal in creating a new form of knowledge generated through encounter and dialogue of the political decision-makers with these subjects. Among numerous others,…

Danno da prodotto e mercati digitali. Verso la responsabilità delle piattaforme di e-commerce

2021

Questo articolo intende ricostruire l'impatto della rivoluzione digitale sulla disciplina della responsabilità da prodotto difettoso al fine di individuare in che modo i mutamenti in atto si riflettano sulla distribuzione delle responsabilità e sul regime giuridico delle piattaforme di e-commerce per danni da prodotti di venditori terzi.

A VR-Enhanced Rollover Car Simulator and Edutainment Application for Increasing Seat Belt Use Awareness

2021

Most countries have active road safety policies that seek the objective of reducing deaths in traffic accidents. One of the main factors in this regard is the awareness of the safety measures, one of the most important being the correct usage of the seat belt, a device that is known to save thousands of lives every year. The presented work shows a VR-enhanced edutainment application designed to increase awareness on the use of seat belts. For this goal, a motorized rollover system was developed that, synchronized with a VR application (shown in a head-mounted display for each user inside a real car), rolls over this car with up to four passengers inside. This way, users feel the sensations …

Asynchronous sensor fusion of GPS, IMU and CAN-based odometry for heavy-duty vehicles

2021

[EN] In heavy-duty vehicles, multiple signals are available to estimate the vehicle's kinematics, such as Inertial Measurement Unit (IMU), Global Positioning System (GPS) and linear and angular speed readings from wheel tachometers on the internal Controller Area Network (CAN). These signals have different noise variance, bandwidth and sampling rate (being the latter, possibly, irregular). In this paper we present a non-linear sensor fusion algorithm allowing asynchronous sampling and non-causal smoothing. It is applied to achieve accuracy improvements when incorporating odometry measurements from CAN bus to standard GPS+IMU kinematic estimation, as well as the robustness against missing da…
