The design of a right contour/structure of the NFC-antenna is presented. The NFC-reader-antenna is applied later to communicate with the NFC-tag (transponder) of a smart phone placed in the phone box of the car. The NFC-reader-antenna with selected contour is printed directly on the PCB and the antenna-PCB is placed under the phone box at the center console. The designed antenna must fulfill ...

INTRODUCTION Enhancement of a single-photon emission is a great demand in recent science and applications, including development novel class of light sources, encoded information transfer and biological imaging [1, 2, 3]. Fluorescence can be improved through excitation and emission enhancement. Improvement of these two processes can be realized by using the near-field enhancement accompanying ...

Recent studies report problems related to premature aging and degradation of high-voltage polymeric insulators. Corona activity, which is induced in areas of high electric field levels, is considered one of the leading causes of these problems. The insulator operation under adverse conditions including rain, fog, dew and pollution is affected by these key factors that modify the electric field ...

A 2nd-generation irradiation target holder is being developed at the High Flux Isotope Reactor (HFIR) of Oak Ridge National Laboratory (ORNL). This 2nd-generation holder design is focused on improving the loading and unloading of the targets by the HFIR operators since a large number of targets are anticipated to be irradiated in the future. Part of the safety analysis required is to ensure ...

The objective was to make a visualisation application for the pupil's lab of the University of Applied Sciences Bielefeld. The application serves as a supplement for a workshop. It should provide a better understanding of a fuel cell, to visualize important influences and collect first experience with a simulation. To achieve this objective, a model of the fuel cell is created. The ...

Microwave heating is known for its efficiency and instantaneity. However, the non-uniformity of the microwave heating has limited the development of its application in industry. In order to solve this problem, a metal patch sticking to the turntable was proposed. During the heating process, the location of the metal patch will change along with the rotation of turntable. Thus, regulate the ...

In this work, we present simulations of a novel micromachined calorimetric flow sensor using COMSOL Multiphysics. The sensor is based on four germanium thermistors that serve as heat sources and as temperature sensors simultaneously. In operational mode, the heated membrane is cooled by any passing flow and the local cooling rate depends on the flow velocity. The simulation results demonstrate ...

In this study, numerical simulations of mixing in turbulent flow, subject to a change in density, are performed. Attention is focused on the binary mixing between two streams of fluid in which a variable density step are formed due to a difference in the temperature. This binary mixing problem performed by assuming low Mach number flow. The results demonstrate the variable density effects and ...

Aging infrastructure requires frequent inspections to assess their structural integrity. However, the large amount of existing infrastructure, and the distance between these structures present significant challenges to inspectors. Acoustics-based technologies represent a simple, and relatively inexpensive, technique to monitor the integrity of a structure. To develop these techniques, designers ...

There is considerable interest in the possibility of combining NTE materials with normal (positive) thermal expansion materials, to reduce the potential of failure of a material or component due to thermal stress fracture. Finite element analysis (FEM) is used to explore the overall expansion and thermal stress in composites.
