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 ... Mehr lesen
Exposure to microgravity is known to alter genomic and proteomic expression and suppress immune cell activity. These changes may influence cancer development. Studying cancer cells in this environment, may help uncover novel therapeutic targets. SUNY Polytechnic Institute and ... Mehr lesen
Manufacturing of pharmaceutical drug substances involves chemical unit operations that are dependent on effective mixing, particularly reactions and crystallizations. Poor mixing can cause uneven distribution of chemical species in stirred tanks, leading to impurity formation and ... Mehr lesen
The objective of this research is to design a millimeter scale broadband energy harvester device through the use of a multi-cantilever beam approach with a non-linear geometry. In this research, we use COMSOL Multiphysics® software to design, simulate and analyze the voltage and power ... Mehr lesen
Ionic polymer-metal composite (IPMC) materials are promising candidates for soft robotics and artificial muscle applications. The primary actuation mechanism in such devices is ion migration in a polymer membrane, localized swelling, and a corresponding overall material deformation, ... Mehr lesen
A dielectric multilayer structure, with a grating profile on the surface layer, can couple light into a strongly confined surface wave, known as a Bloch surface wave. These surface modes can be used to design bio-sensors. The corrugated surface structure also enables azimuthal angular ... Mehr lesen
INTRODUCTION: Abnormalities in local body surface temperature have been recognized as a sign of disease for centuries, much before humans knew about the cause of ailments or of pain [1]. The idea of this work is to use numerical simulation tools to predict the location, size and ... Mehr lesen
Permanent magnets are ubiquitous in our world today, from refrigerator magnets to industrial sensor applications. Often, the magnitude of the field at a specific distance from an arbitrarily shaped magnet of variable strength is a necessary parameter for end-use systems. We used the the ... Mehr lesen
Radio frequency (RF) micro-electro mechanical system (MEMS) switch works in on/off modes controlled by electrostatic forces. In off mode, rough surfaces of electrodes come into a contact. Membrane contact surfaces have complex surface roughness patterns and the mechanical contact problem ... Mehr lesen
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 ... Mehr lesen
