Energy shaping is a remarkably effective control strategy which can be applied to wide range of systems, including underactuated mechanical systems. However, research in this area has generally neglected actuator dynamics. While often appropriate, it might result degraded performance the case fluidic actuation. In work we present some new results on energy for systems action mediated by pressur...

In this paper we prove a recent conjecture [Robnik M and Salasnich L 1997 J. Phys. A: Math. Gen. 3

increasing of word demand load caused a new distributed generation (dg) to enter to powersystem. one of the most renewable energy is the photovoltaic system. it is beneficial to use thissystem in both separately as well as connected to power system using power electronics interface.in this paper an optimal pid controller for photovoltaic system systems has been developed. theoptimization techni...

A novel, integrated micromechanical actuator based on the principle of undulatory fish locomotion and intended for efficient on-chip cooling or venting applications is conceived and designed for an aluminum nitride-based thin-film technology applying coupled piezoelectric, mechanical, and fluidic analyses. The results of the investigations prove that an undulatory motion of the fin-like micro-f...

Self-Driving Fluidic Micro-Processors In article number 2200017, Milad Abolhasani and co-workers present a self-driving lab using artificial intelligence-guided fluidic blocks for accelerated fundamental applied studies of emerging clean energy materials. Autonomous doping metal halide perovskite quantum dots is demonstrated as material testbed this lab.

Ultrasound is an attractive modality for controlling micro/nanorobots due to penetrating deep into tissue, not being affected by the opaque nature of animal bodies, and generating a broad range forces. However, ultrasound microrobots have poor navigation capabilities number parameters involved in its motion make it extremely challenging human controller accurately predict manually correct micro...

M q ðxÞ 1⁄4 x T q ðxÞ x T q ðxÞ: (5) Since Jþi is a leading-twist operator, it is clear that such a simple partonic interpretation should exist. However, Ji, Xiong, and Yuan misleadingly interpret Jþi as the transverse angular momentum operator. Indeed, in light-front quantization, the role of time is taken by xþ, so that Jþi is the light-front transverse boost operator. In terms of the more co...

In this paper, we emphasize our long series of experiments proving that the physical processes along fluid interfaces can be exploited for creating unusual fluidic objects. We report for the first time a couple of new fluidic objects so-called “liquid onions” and “mayonnaise” droplets. The study starts from the observation of antibubbles, exhibiting unstable liquid–air–liquid interfaces. We sho...

Two methods of attaching fluidic interconnects are presented. By using gold to gold fusion bonding and copper to gold fusion bonding, micro-scale tubes are attached to a MUMPS fabricated fluidic channel. The fusion bonding is done by resistively heating a gold layer on top of the poly 2 layer, so that the gold melts. A range of different heater geometries is presented. The tensile and shear str...
