In this work the influence of solid particles concentration from suspension on the buildup evolution for a single wire from a magnetic filter working in axial configuration is presented. The buildup differential equations are solved and the surface contour of the buildup at different moments is obtained. It is evidenced the existence of a suspension concentration for which the radial deposit ex...

We discuss the development and design of a Biomimetic Electrostatic Imaging (BEI) element for use in a future multichannel imaging instrument. Inspiration for electrostatic sensing is provided by the diverse species of fish that use passive and induced electric fields for hunting, defense, localization, and communication. Designing an electrostatic sensor is not without its challenges. Hardware...

In this work it is shown that one of the most employed filtering systems for use in continuous-flow industrial microwave ovens, namely doubly corrugated filters, does not work properly for many values of the electric permittivity of the processed material when it is partially filled. Thus, a novel bandstop filter which solves these inconveniences, based on a combination of metallic irises and d...

electric wheelchairs (ew) experience various terrains surfaces and slopesas well asoccupants with diverse weights. this, in turn, imparts a substantial amount of perturbation to the ewdynamics. in this paper we make use of a two-degree-of-freedom control architecture called disturbance observer (dob) which reduces sensitivity to model uncertainties while enhancing rejection of disturbances caus...

Lithium ion batteries have proven themselves the main choice of power sources for portable electronics. Besides consumer electronics, lithium ion batteries are also growing in popularity for military, electric vehicle, and aerospace applications. The present review attempts to summarize the knowledge about some selected membranes in lithium ion batteries. Based on the type of electrolyte used, ...

The most common cause of high voltage electric machine malfunction is an electrical failure of the insulation system due to extreme partial discharges activity. The paper discusses the methodology for the construction of a low-pass high voltage filter for partial discharge measurement. It focuses mainly on the shape optimization, using an analytical approach with subsequent verification using t...

The electric machine emulator (EME), using digital simulation and power electronics to emulate the characteristics of actual machines, can greatly accelerate testing drives. However, most existing EMEs are based on typical L filter linear controller, which causes control conflicts bandwidth limitation. To address this issue, paper presents an EME LCL with passive damping for a three-phase perma...

Dielectrophoresis (DEP), a nonlinear electrokinetic transport mechanism, can be used to concentrate and sort cells, viruses, and particles. To date, microfabricated DEP-based devices have typically used embedded metal electrodes to apply spatially nonuniform, time-varying (AC) electric fields. We have developed an alternative method in which arrays of insulating posts in a channel of a microchi...

the notion of absorbent ordered filters in implicative semigroupsis introduced, and its fuzzification is considered. relations among (fuzzy) orderedfilters, (fuzzy) absorbent ordered filters, and (fuzzy) positive implicativeordered filters are stated. the extensionproperty for (fuzzy) absorbent orderedfilters is established. conditions for (fuzzy) ordered filters to be (fuzzy)absorbent ordered ...
