Summary: This paper investigates the fault detectability of Boolean control networks and proposes passive fault detectability and four types of active fault detectability. Discriminant conditions and algebraic criteria for verification are provided. The relationships between different types of active fault detectability are discussed, and an approach for calculating fault detection time is given.

Summary: This study numerically and experimentally investigates the flow over a slitted (0.1D) cylinder at Re = 100 with varying slit angles (0 degrees - 90 degrees). The numerical solution solves the Unsteady Reynolds-Averaged-Navier-Stokes (URANS) equations and analyzes coefficients of lift (CL) & drag (CD), velocity, and vorticity. The experimental part visually validates the scalar data of the flow pattern using soap film and a high-speed camera. The study observes passive and active control of the slit's effects on lift, drag, and injection and blowing/suction modes.

Summary: This study investigates a wickless two-phase heat spreader with boiling heat transfer for thermal management of hot spots with a high heat flux. Thermal management studies are performed using two different approaches: fabricating a boiling-driven heat spreader to confirm thermal performance, and establishing the working mechanism of the heat spreader for visualization and observation of boiling/condensation phenomena. The proposed advanced boiling-driven heat spreader with improved thermal performance is suitable for dissipating highly concentrated heat in various thermal management applications.

Summary: Single-layer and multilayer alloy deposits were electroplated onto a mild steel substrate, consisting of Zn and Fe alloys with different compositions. The corrosion resistance of these deposits was evaluated using potentiodynamic polarization method, while their surface morphology, crystal structure, and Fe content were characterized using scanning electron microscopy, X-ray diffraction, colorimetry, and energy-dispersive X-ray spectroscopy, respectively. The microhardness of the coatings was measured using a Vickers indenter. It was found that the Zn-Fe multilayer coatings showed significantly improved corrosion resistance compared to the single-layer coating, making them crucial for the automotive industry and steel-based vehicle parts.

Summary: Tracking the plating and stripping behaviours of lithium metal in real time using operando synchrotron X-ray tomographic microscopy reveals the formation of inactive lithium microstructures. Efficient lithium metal stripping and plating operation is crucial for safe lithium metal batteries. However, monitoring the evolution of lithium metal microstructures during cell cycling is challenging.

Summary: This study reveals that trace amounts of chloride ions in the electroplating bath are the source of active chlorine species that accelerate the breakdown at the insoluble anode. A sacrificial perfluorinated polymer coating effectively reduces the emission of active chlorine species from the electrode, thereby decreasing the consumption of brightener during Cu electrodeposition.

Summary: This study introduces a method of robotic rock-and-walk manipulation for dynamic, nonprehensile object locomotion. By periodically rocking the object, it is able to roll along a zigzag path and achieve forward walking while in contact with the environmental surface. Rock-and-walk is a special-purpose method used for transporting large and heavy objects that cannot be handled with other primary methods. The authors conducted a detailed study of the object-robot-environment system's dynamics, kinematics, and mechanics, and developed a feedback control strategy to regulate the object's energy and posture for rock-and-walk gaiting. Extensive experiments demonstrated the feasibility and practicality of their approach in various settings.

Summary: This study systematically investigated the morphologies and textures of Re coatings electrodeposited under different conditions, and determined the optimal deposition process range to be 800-850 degrees C and 50-100 mA/cm(2). The average microhardness of the Re coatings deposited at 50 mA/cm(2) in the temperature range of 800-850 degrees C was around 377 kg/mm(2).
