Historical awareness support and its evaluation in collaborative software engineering [PDF]
, 2003 The types of awareness relevant to collaborative soft- ware engineering are identified and an additional type, "historical awareness" is proposed. This new type of awareness is the knowledge of how software artefacts re- sulting from collaboration ...

Internal Induced Voltage Modification for Current Limitation in Virtual Synchronous Machine
Energies, 2022 Virtual inertia control is a methodology to make inverter-based resources (IBR) behave like a synchronous machine. However, an IBR cannot fully emulate the response of synchronous machine because of its low-current capacity. When the inertial response of

Information Transmission Strategies for Self‐Organized Robotic Aggregation
Advanced Robotics Research, EarlyView.In this review, we discuss how information transmission influences the neighbor‐based self‐organized aggregation of swarm robots. We focus specifically on local interactions regarding information transfer and categorize previous studies based on the functions of the information exchanged.

A Novel Pre-Synchronization Control for Grid Connection of Virtual Synchronous Generator
Elektronika ir Elektrotechnika, 2020 The virtual synchronous generator (VSG) introduces rotational inertia and damping through the droop control to take part in frequency regulation of the grid. By building the VSG model, the VSG controller, including both the frequency controller and the excitation controller, are analysed and designed.

Tumbling Magnetic Microrobots for Targeted In Vivo Drug Delivery in the GI Tract
Advanced Robotics Research, EarlyView.We introduce a microrobot design and integrated system for on‐demand targeted drug release in the gastrointestinal tract. The microrobot has an embedded magnet for actuation with external magnetic fields and is visualized in real time using ultrasound. It has two drug release ports sealed with a thermally sensitive wax. Local heating of the wax using a
