We have designed a new type of optical channel drop filter (CDF) based on two dimensionaltriangular lattice photonic crystals. CDF operation is based on coupling to the photonic crystalwaveguide. The proposed structure is optimized to work as a CDF for obtaining the CDFcharacteristics and band structure of the filter the finite difference time domain (FDTD) method andplane wave expansion (PWE) ...

generally, studied villages as regard to the socioeconomic structure have not considerable development in comparison with their around structure due to functional area.  nowadays, regarding rural development, proceeding with economical analysis of geographical areas has a great position. considering the applied investigations, upon increasing the knowledge and literacy and scientific and practi...

this paper proposes a new method of gain scheduling control design for a nonlinear system which is described as linear parameter varying form. a performance measure based on linear matrix inequality is introduced. to consider stability and performance measures in design process, the h∞ loop-shaping method is used to design the local controllers, which can be described as state feedback observer...

background: sigma factors are proteins that regulate transcription in bacteria. sigma factors can be activated in response to different environmental conditions. the rpos (rna polymerase, sigma s) gene encodes sigma-38 (σ38, or rpos), a 37.8 kda protein in pseudomonas aeruginosa (p. aeruginosa) strains. rpos is a central regulator of the general stress response and operates in both retroactive ...

The paper introduces a new approach to preference structure, where from a weak preference relation derive the following relations:strict preference, indifference and incomparability, which by aggregations and negations are created and examined. We decomposing a preference relation into a strict preference, anindifference, and an incomparability relation.This approach allows one to quantify diff...

The trans-admittance-mode (TAM) might act as a transforming bridge for voltage-mode to current-mode conversion. In this study a new low voltage operated electronically tunable TAM biquad filter structure realizing all the seven standard filtering functions namely; low-pass (LP), band-pass (BP), high-pass (HP), regular-notch (RN), low-pass-notch (LPN), high-pass-notch (HPN) and all-pass (AP) fro...
