The paper deals with the development of a Power Hardware-In-the-Loop (PHIL) simulator using parallel connected Active Neutral Point Clamped (ANPC) bridge arms. The parallel connection offers better emulation precision due to the increased number of available voltage levels and the higher apparent switching frequency. The concept to emulate the transient inductance and the inner voltage of an AC machine is introduced and analyzed in a single phase model using interleaved modulation in the parallel arms, and level shifted carriers for the upper and lower side of the arms. The static and dynamic precision of the emulation is influenced by the current balancing applied for distributing the power evenly on the parallel arms. A compromise is required to keep both the emulation and balancing error at low level.

The first evidence for the Higgs boson decay to a Z boson and a photon is presented, with a statistical significance of 3.4 standard deviations. The result is derived from a combined analysis of the searches performed by the ATLAS and CMS Collaborations with proton-proton collision datasets collected at the CERN Large Hadron Collider (LHC) from 2015 to 2018. These correspond to integrated luminosities of around 140 fb−1 for each experiment, at a center-of-mass energy of 13 TeV. The measured signal yield is 2.2±0.7 times the standard model prediction, and agrees with the theoretical expectation within 1.9 standard deviations.

The advances in FPGA technology have enabled to develop fast HIL (Hardware-in-the-Loop) simulators, revolutionizing control software and hardware development for power electronics. HIL simulators should reproduce the same analogue signals that could be measured on real main circuits. A very common limitation in these applications is the usable pin count of the FPGA, therefore using the most pin-effective Digital-to-Analogue Converters (DACs) becomes critical. Σ-Δ DACs provide a simple, FPGA-synthesizable solution using a single pin for each output, but the output signal's bandwidth and latency is usually not sufficient, because of the required analogue filters. Higher order Σ-Δ DACs usually perform much better in the aspect of the Signal-to-Noise-Ratio (SNR) but not the usable bandwidth. This paper introduces a new bitstream DAC architecture based on the sliding mode control of the output analogue filter model. It is optimized mainly to reproduce current transducer signals in power electronics (usually triangle waves), which can be done more accurately than traditional Σ-Δ solutions.

The free-climbing robots are the alternative to wheeled vehicles, because the legged locomotion allows mobility on the steep gradients under the harsh environmental conditions. The steady progression requires coordination of leg movements for which the force sensors implemented in the joints of the robot legs are not always sufficient. Considering the previous developments in the field of robotics, the combination of the impedance and vision sensors comprises an obvious solution for providing stable and accurate contact between the individual legs and the ground. The implementation of additional, non-invasive sensor/s on all the legs of the hexapod robotic platform, for the indirect measuring and analysis of the terrain surface, is investigated. Furthermore, a method for the parametric 3D modeling of simulation assemblies is described in a mixed top-down, bottom-up and middle-out design approach. Mechanisms were created using the common origin skeletal modeling (top-down approach), allowing the context analysis and the definition of the parameters for the further numerical optimization in an early phase of the development. Finally, the applicability of the anytime approach during the optimization of the mechanical parts of the mechanism in the design process was tested.

This paper introduces a new five level resonant DC/DC converter and examines its operation in steady-state symmetrical conditions in discontinous current conduction mode. The converter has four outputs, which can provide four equivalent voltage levels or four different ones as well. It has several advantages such as improved performance at high efficiency and lower EMI. By using this converter, zero voltage and zero current switching is possible which helps reducing the swtiching losses. The most important relations among the input, output, and control variables will be derived and verified by simulation results. Three control variables will be examined in the paper, switching angle α_p[°], capacitor peak voltage V_c~* [pu] and switching frequency f_s~* [pu]. Parameters V_c~* and α_p are dependent variables, while f_s is independent of them. This converter can be applied in UPS systems or in multi-level inverter drives as well.

Development of driverless road vehicles is one of the most active research areas of robotics today. Path planning among obstacles is one of the challenging problems to be solved in order to achieve autonomous navigation. In this paper we present a geometric path planning approach for car-like robots, intended for generating good quality paths even in cluttered environments containing narrow areas. The presented planner is designed to cope with situations which need nontrivial maneuvering between obstacles. The resulting paths are similar to those a human driver would find and have continuous curvature profile, which makes them appropriate for application on real cars. A comparative analysis of our method with possible alternatives in the literature is presented to illustrate its effectiveness regarding path quality and computation time.

Participatory Computing is the concept of a group of computers contributing processing power and storage to form a larger, distributed computing system. Past experiences show that a system of this type can reach performance rivaling the fastest supercomputers in the world. In theory, any connected modern PC could participate and yet the prevalence of these systems is not comparable to their potential numbers. In this paper, we analyze the main barriers ahead the larger adaptation of participatory systems and propose solutions around them. Ultimately by applying these solutions we prove their workability by showing and evaluating a proof-of-concept system and measurements related to it. The proposed results can offer several advantages in the field of participatory computing where the new technologies are applied.
