Frequency stability and Synthetic inertia
Abstract. Due to low inertia, stochastic nature of renewable energy sources and sudden load changes, nearly all the modern microgrids are associated with the dynamic frequency stability issues. Thus it restricts the maximum number of the renewable energy systems that can be penetrated to the microgrid. In order to increase the low inertia sources penetration to the microgrid, the frequency stability issues need to be addressed. The frequency stability issues of a typical microgrid are addressed by the addition of extra inertial support from the power sources using power converters and appropriate control loop. In this talk the readers are introduced with the basic concepts of the synthetic inertia support for the dynamic frequency stability issues of a hydro-PV microgrid. The details of the frequency –power response based synthetic inertial support and current control loops are elaborated using a simulation example. The deviation in system’s frequency is usually compensated by sourcing or absorbing the active power by the inertial support loop, so by utilizing the concept of inertial loop, the maximum number of RESs integration can be enhanced.

Exoskeletons in Rehabilitation Medicine
Abstract. Rehabilitation medicine applies two important strategies in fighting disability: functional restoration and functional compensation. The use of new assistive technology actually enhances functional recovery and the dividing line between the two begins to vanish, making place to an integrated approach.
Here comes the large variety of exoskeletons, providing safe and corrective assistance and, at the same time, support for functional training in what matters most, namely performing activities of daily living. Accurately compensating deficits and meeting real life functional needs of their users, last generation powered exoskeletons became already efficient tools of rehabilitation medicine.

Unsteady Flow and Sound Generation in Centrifugal Ventilators
Abstract.Generation of hydrodynamic noise in the flow section of centrifugal fans occurs due to various non-stationary flow phenomena: hydrodynamic interaction between the flow leaving the impeller and the fan volute casing due to stepwise non-uniformity of the flow at the impeller outlet; vortex phenomena which is expressed as small-scale turbulence in the boundary layer, formation of turbulent wakes during streamlining of housing elements, and generation of large-scale vortex structures and separation flows. Detailed studies of flow parameters in absolute and relative motion at the centrifugal impeller outlet confirm that flow in the blade channel and at the outlet of the centrifugal impeller can be subdivided into two areas – a high-energy stream and a low-energy zone of the wake. This gives substantial non-uniformity of relative and absolute velocities and angles of the flow across the impeller grid spacing, since the low-energy area adjoins the trailing side of the blade and velocities and angles of the flow are higher at the front side of the blade. Due to the non-uniform flow discussed above, the passing of the impeller blades generates BPF pressure pulsations and, as a rule, amplitudes of BPF tone components dominates in the spectra of noise and pressure pulsations in design. Pressure pulsations depend on profiling of the ventilator impeller and woking cavity. In ventilators the length of acoustic waves can be comparable to the size of the casing.The amplification of pressure pulsations can happen due to matching of frequencies of oscillations with acoustic resonance frequencies.Various numerical studies of BPF pressure pulsation in centrifugal ventilators are undertaken using the method and software package based on a representation of non-stationary motion of a compressible medium as a superposition of acoustic and vortex modes. In this case non-linear equations for unsteady vortex motion of an incompressible liquid are solved with a bigger time step. Wave equation relative to the pressure pulsations taking into account acoustic impedances on the borders of computational domain is solved by an explicit method.

HYDROïD: New Humanoid platform with Integrated Hydraulic Actuation technology
Abstract. HYDROïD (HYDraulic andROïD) is a full-size under development humanoid robot aims to contribute to improving our understanding of the phenomena of locomotion and manipulation of humans. Humanoid with hydraulic actuation are able to achieve hard and useful tasks and
replace human in disaster environment.
In hydraulic actuation, pistons are used to produce motion. At least one hydraulic piston
is implemented for each degree of freedom (DoF). The main difficulty is how to bring hydraulic energy to each piston. Hydraulic pipes are usually employed to drive hydraulic power from the control unit to pistons. Each piston needs two pipes, one to drive fluid “in” and the other to drive it “out”. In robotic applications, flexible hydraulic pipes are used to drive the oil in parallel to the joints. This solution suffers from three main disadvantages: I) The hydraulic pipes connected in parallel to joint will give a spring effect. This phenomenon has to be considered while developing the control law. II) The more the number of pipes, the more of the leakage probabilities. III) External pipes increase dramatically the robot size and decrease its anthropomorphic aspects.
To answer all these questions, a new “integrated hydraulic actuation” method was proposed and implemented on HYDROïD. The goal is to eliminate all external pipes and replace them with integrated hydraulic passages. Fluid paths is integrated internally through the mechanical structure and not externally through pipes. In other words, “arteries” and “veins” were built inside the HYDROïD body to drive hydraulic fluid like blood in human body.
This presentation will focus on two research areas. First, we will focus in two innovative hybrid mechanisms, each consisting of a rotating actuator carrying a parallel structure with two active DoF. The first type has been dedicated to the modules of the hip, shoulder and torso. The second type, actuation of parallel structure with cables was chosen for the ankle, the wrist and the neck modules.
The second part of this presentation will be dedicated to the actuation of the HYDROïD robot for which a new highly integrated actuator has been proposed. The actuation principle will be detailed and the benefits of the proposed solution will be shown. Very interesting performance of the realized prototype will be presented.

Liquid injectors for the revolutionary combined rocket engine reveal unusual features
Abstract: Experimental flow characteristic of the injection head isued through experimental evaluation of the revolutionary ORVEAL combined rocket engine add new and unexpected findings. The presentation shows evidence of this experimental phase, after the years of theoretical and design labor upon the new engine and combustion method, patented by ADDA LLC. The ubiquitous approach of injection characteristic based on the Bernoulli law and a constant flow rate coefficient proves far from applicable for the specific injector head. A pressure law with the power smaller than 1⁄2 was found more adequate. Such a law is not met in the known literature and could open a debate. This finding is only proved for the specific ORVEAL design, that involves the anti-return nozzle injectors, patented by ADDA to avoid reversed flows and could remain a specific feature. Confidence in the new and unexpected injector characteristic required refined measurements, which were performed by means of a HAMEG make, high accuracy oscilloscope, especially prepared by the manufacturer for ADDA. The theoretical explanation of the experimental evidence remains to be obtained as well as additional confirmation of the present, unexpected findings. This presentation is aimed to subject experimental facts to the attention of interested researchers and open a path for further investigation on the subject. Integration of the combined rocket engine into the SPARTACUS orbital socket vehicle is also scketched.

Multi Objective optimization of the dynamic behaviour in Robotics
Abstract. Multi objectives optimisation in the dynamic behaviour of robots is one of the most difficult problem to be solved. In the paper will be shown the complex matrix form of the active forces and moments in the robot's joints, the mathematical models for the inertial tensors for different form of the robot's body and the proper algorithm to establish the best case between some studied cases when were changed: the movements- simultaneously, successive or combination of them; the dimensions of the bodies; the constant velocity of each trapezoidal characteristics; the acceleration and deceleration time. The mathematical matrix form of the active forces and moments equations were transposed in to the virtual LabVIEW instrumentation with the goals to obtain some characteristics of the active forces and moments variation vs. time in each joints of the robot, in the cases when were changed some functional or constructive parameters. In controlling the movements of the end-effector and joints of a manipulator in the workspace, an important problem is to identify the joints’ best relative displacements to assure extreme precisions for the end-effector movements. Applications where multiple manipulators with a common controller to be controlled in 3D space are more challenging compared to single robot control since the movements of the end-effectors of all robots must be determined using complex forward (FK) and inverse kinematics (IK).The presented method is a multi-objective technique with the employed Virtual LabVIEW Instrumentations (VI) for the assisted research of the robot joint’s moments that could be generalized to other robots tracking for any conventional and unconventional space curves. By using proper optimization algorithm was choose the best solution between all these studied cases. The applied method, the algorithm and the proper virtual instrumentation solve one small part of the complex problems of the optimisation of the dynamic behaviour in robotics.
