Pipeline inspection tools present some limitations related to power supply which require recharging after each operation. Using batteries or tethered tools make the duration to inspect any pipeline very limited and time consuming. This paper aims at designing a spherical self-recharging ... Read More

INTRODUCTION: Point-Of-Care (POC) and home care systems are of growing importance in biotechnological and medical applications [1]. These devices allow health monitoring directly at home or at the doctor’s office. Portability, low-cost, easy handling and compatibility with telemedicine ... Read More

This paper reports on the application of COMSOL Multiphysics’ Richard\'s Equation Interface in the assessment of irrigation moisture sensors for detecting the level of water saturation in a spatial variably saturated soil. The Richard\'s Equation (in COMSOL) provides the interface which ... Read More

Thomas Herrmannsdörfer got his PhD in experimental physics from the University of Bayreuth in 1994. In 1995, he received the Research Award of the Emil-Warburg-Foundation while he worked at the DFG-Graduiertenkolleg Bayreuth. From 1995 – 1998 he worked as a scientist at Hahn-Meitner ... Read More

Acoustic streaming (AS) describes a physical phenomenon where an oscillating sound emitter induces a steady fluid motion. Metal processing industry applies this treatment for grain morphology adjustments during the solidification of metal. Improvement and further development of this ... Read More

In our study of chaotic mixing, 3D velocity measurements (u,v,w) are required for evaluation of a micro mixer using a mix-prediction algorithm. The hybrid approach presented here combines 2D measurements, an imperfect numerical model, and appropriate fitting parameters. Because our ... Read More

Vortex ring can be useful to generate thrust force for e.g., jellyfish, but its mechanism has not been clarified. In this field, it seems that numerical simulation has an important role of understanding the propulsion mechanism of creature. A vortex ring in a tube, refered to confined ... Read More

Significant submarine mineral deposits form when hot, metal-laden, saline fluids emerge onto the seafloor and mix with ambient seawater. Resulting density changes of fluid mixtures can trigger fluid buoyancy reversals, brine pool formation, and metal accumulation (Figure 1). While some ... Read More

Insulator-based dielectrophoresis (iDEP) employs arrays of electrically insulator posts in a microfluidic device to create dielectrophoretic forces that affect particle movement (Figure 1). The trapping performance of iDEP devices involves a careful balance between electrokinetics (EK) ... Read More

In this work, we present a number of scoping calculations that have been carried out to design an in-situ redox experiment (Figure 1) focused on assessing potential changes in the pH and redox conditions and in the buffering capacity of the Olkiluoto bedrock (i.e. the site for the ... Read More
