This study proposes a novel square/triangular wave generator based on a dual outputs differential voltage current conveyor (DO-DVCC). The proposed circuit uses one DO-DVCC combined with three grounded passive components. The presented scheme reveals a compact topology and can produce square/triangular waveform simultaneously. To verify their feasibility, commercially available ICs were used for...

This paper presents a dual-mode modeling approach based on innovation design and engineering design, which is applied to the design of belt conveyor. Dual mode modeling method fusions innovation design pattern and engineering design mode, and realizes a combination of liberalization design and precision design, while the traditional parametric modeling is restricted by single thought, which exi...

In this note we show that a Noetherian module has a dual module if and only if it satisfies AB5*. A connection between completeness and AB5* is also established. In this note we relate completeness, quasi-completeness, the A B5* condition, and duality. The main result is that a Noetherian R-module has a dual module if and only if it satisfies A B5*. Throughout this note R will denote a commutat...

A co-volume scheme is introduced for the rotating shallow water equations, in which both velocity components are specified on cell edges, and the thickness variables evolve on both the primary and the dual cell centers. The scheme applies to generic, conforming and non-orthogonal staggered grids, including the widely used lat-lon quadrilateral grids and the Delaunay-Voronoi tessellations. It ca...

This paper presents a single feed rectangular micro strip patch antenna and a different approach to design dual and triple band antennas using triangular slots on patch. Three triangular slots are there for triple band in this design, two triangular slots are above the feed point one triangular is near the feed point. A triple band antenna for 3.65 GHz, 4.11GHz and 6.48 GHz applications using s...

This paper deals with ridge estimation of fuzzy nonparametric regression models using triangular fuzzy numbers. This estimation method is obtained by implementing ridge regression learning algorithm in the La- grangian dual space. The distance measure for fuzzy numbers that suggested by Diamond is used and the local linear smoothing technique with the cross- validation procedure for selecting t...

Abstract We compute spectra of symmetric random matrices defined on graphs exhibiting a modular structure. Modules are initially introduced as fully connected sub-units of a graph. By contrast, inter-module connectivity is taken to be incomplete. Two different types of inter-module connectivities are considered, one where the number of intermodule connections per-node diverges, and one where th...

We describe a smart-pixel circuit that permits the use of a GaAs/AlGaAs multiple quantum well diode to be used both as a detector for data input and a modulator for data output. The module provides the ability to double the number of inputs or outputs to the array and is well suited to cascaded optoelectronic system architectures that require bidirectional communition.
