In this letter, we present techniques, utilizing dielectrophoresis and electrohydrodynamics, which can be used for assembling single-crystal silicon devices suspended in a solution onto a binding site on a heterogeneous substrate. Silicon resistors with gold/chromium layers located at the end of the resistors and silicon blocks without metal were fabricated on bonded and etched-backed silicon-o...

A technique for implementing monolithic resistors with a desired temperature coefficient (TC) over a wide temperature range is introduced. A typical monolithic resistor consists of a core resistive layer terminated with contact layers on each end. In a typical process, there are core resistive layers that have TCs with opposite sign of that of the contacts. The authors propose to take advantage...

A novel configuration for realizing voltage/current-mode (VM/CM) universal filter using a single four terminal floating nullor (FTFN), a single current feedback amplifier (CFA), two capacitors and three resistors is presented. The VM configuration has three inputs and a single output and implements all the five generic filtering functions through the selection of inputs. This topology enjoys ca...

Efficient maintenance and upgrading of a building during its lifecycle are difficult because a cementitious finish uses materials and parts with low disassembly properties. Additionally, the reuse and recycling processes during building demolition also present numerous problems from the perspective of environmental technology. In this study, an induction heating (IH) method was used to disassem...

This research proposes a new neural network for text categorization which uses alternative representations of documents to numerical vectors. Since the proposed neural network is intended originally only for text categorization, it is called NTC (Neural Text Categorizer) in this research. Numerical vectors representing documents for tasks of text mining have inherently two main problems: huge d...

Current-sensing topology with multi resistors in series has limitations improving the dynamic range of current acquisition, so a sensing parallel is proposed. The overcurrent state shunt circuit cannot be latched, resulting protection hiccups. A dual threshold-detection designed to achieve latching and self-recovery. rectified mean applied for magnitude detection its validity proved. But delay ...
