In this paper, two compact quad-channel and six-channel diplexer are designed and fabricated using defected microstrip structure (DMS). This structure is designed for the desired frequency based on the literature reviews. The proposed configuration is composed of a conventional T-junction divider with two pairs of open bended stubs and dual/tri-band filters. In designing dual band filters, a lo...

Boolean equivalence checking is a well established approach for verifying combinational circuits and is on the verge of becoming an integrated part of the design cycle. In [12], we have presented a method for performing automatic error correction in combinational circuits if equivalence checking fails. However, like all other automatic error correction techniques proposed in the past, it cannot...

In this work, a novel nonlinear filter, called tri-state median (TSM) filter, is proposed for preserving image details while effectively suppressing impulse noise. We incorporate the standard median (SM) filter and the center weighted median (CWM) filter into a noise detection framework to determine whether a pixel is corrupted, before applying filtering unconditionally. Extensive simulation re...

We propose a multicast-capable free-space optical switch using tri-state switching elements (SEs) and investigate its complexity and loss. We also show that an N-input M-output multicast-capable switch requires only N ·M non-movable tri-state SEs. OCIS codes: (060.1810) Buffers, couplers, routers, switches, and multiplexers; (060.4255) Networks, multicast.

Conventional two-state dc to dc voltage converters have in their small signal transfer function a right half planzero in pole-zero plane whichthis zero result in speed reduction and lowfrequency operation, especially, because position of the zero is not fixed andmovesby the load variation. To remedy this problem the tri-state boost converters have been introduced. These converters haven’t the m...

This project represents a continuous effort of Mauch Laboratories toward the improvement of artificial limbs, particularly for the lower limbs. Work on five items has been underway : A semivoluntary Swing and Stance Control knee mechanism (S-N-S System), an automatically controlled Tri-axial Ankle mechanism, a fully Voluntarily Actuated Swing and Stance Control knee mechanism, a mechanical low-...

Transgenerational epigenetic inheritance, while poorly understood, is of great interest because it might help explain the increase in the incidence of diseases with an environmental contribution in humans, such as cancer, diabetes, and heart disease. Here, we review five Drosophila examples of transgenerational epigenetic inheritance and propose a unified mechanism that involves Polycomb Respon...
