This paper proposes a control structure for a heterogeneous leader-follower formation involving an unmanned ground vehicle (UGV) - the leader, and an unmanned aerial vehicle (UAV) - the follower, based on their kinematic models. The control architecture is a centralized one, in which it is possible to get the robots sensory data and to synthesize and deliver the control signals necessary to establish the formation. The experimental platform, the mathematical models of the robots and other structures needed to carry out the cooperative navigation are detailed. The closed-loop system stability is demonstrated and the effectiveness of the proposed methodology is validated through experimental results.

A fully homomorphic encryption system hides data from unauthorized parties, while still allowing them to perform computations on the encrypted data. Aside from the straightforward benefit of allowing users to delegate computations to a more powerful server without revealing their inputs, a fully homomorphic cryptosystem can be used as a building block in the construction of a number of cryptographic functionalities. Designing such a scheme remained an open problem until 2009, decades after the idea was first conceived, and the past few years have seen the generalization of this functionality to the world of quantum machines. Quantum schemes prior to the one implemented here were able to replicate some features in particular use-cases often associated with homomor-phic encryption but lacked other crucial properties, for example, relying on continual interaction to perform a computation or leaking information about the encrypted data. We present the first experimental realisation of a quantum fully homomorphic encryption scheme. We further present a toy two-party secure computation task enabled by our scheme. Finally, as part of our implemen-tation, we also demonstrate a post-selective two-qubit linear optical controlled-phase gate with a much higher post-selection success probability (1/2) when compared to alternate implementations, e.g. with post-selective controlled-Z or controlled-X gates (1/9).

This paper proposes a shunt active power filter (SAPF) composed of four H-bridge converters. Each of them is connected by means of isolation transformers. Compared to conventional topologies, the proposed converter permits reducing: dc-link voltage rating, grid current harmonic distortion and/or switching frequency (switching losses). A suitable control strategy to adjust the filter currents as well as dc-link voltage are presented. Two PWM strategies are designed to command the converter according to the reference voltage provided by the controllers. Simulation and experimental results are presented in order to validate theoretical approaches.

This paper proposes a complex system optimization method to solve economic emission load dispatch. First, a real-world economic emission load dispatch is modeled as a complex system problem, and the optimization objectives include economic load dispatch, emission load dispatch and transmission network loss. Then a called BBO/complex method is introduced, which extends biogeography-based optimization to a multi-archipelago environment to suit the structure of complex systems. Finally, the proposed method is applied to the economic emission load dispatch, and the results show that it can obtain good performance for economic emission load dispatch studied in this paper, and it is a competitive algorithm for solving complex system optimization problem.

This study is to investigate the main operating mechanism of zinc oxide layer of ZnO RRAM (Resistance Random Access Memory). This experiment prepared four types of ZnO RRAM under different thermal annealing temperatures, Keithley 4200 measurement system was used to measure the operating voltage and current under a high impedance state and a low resistance state into the dielectric layer transmission mechanism analysis. This study found that the operating mechanism of a zinc oxide layer under the low-resistance state is mainly ohm conduction state. However, the operating mechanism of a zinc oxide layer under the high-resistance state is Poole-Frenkel Emission.

This paper presents a methodology for developing an adequacy assessment of the generating and storing mix capacity in nearly-Zero Energy Residential Buildings (nZEB). The adequacy of a given generating and storing mix will be quantified by means of a set of reliability indices obtained by adapting the traditional reliability techniques employed in power systems. The analysis will use a Montecarlo based sampling, to obtain the hourly load and generation profiles of the buildings. Then, the obtained profiles will be used together with the building management system (BMS) model and the energy storage system (ESS) model for obtaining the desired reliability indices. © 2015 IEEE.

The traditional control strategy of hydraulic flight motion simulator (HFMS) cannot meet the high tracking performance requirement, and the control precision is sensitive to disturbance. This paper presents an adaptive inverse controller based on the Wiener-type recurrent neural network (WRNN) to deal with the parametric uncertainties and uncertain nonlinearities in HFMS. The WRNN is a dynamic linear subsystem cascaded with a static nonlinear subsystem. The controller contains two WRNNs, one to identify the Jacobian information of the controlled plant and another to approximate the inverse model of the plant. Since the inverse transfer function behaves sensitive to the initial value, a feedback controller is designed. The input of the controlled plant includes the feedback controller output and the WRNN inverse controller output. Simulations have confirmed the effectiveness and superiority of the proposed WRNN adaptive inverse control strategy. © 2015 IEEE.
