AUTOMATIC GENERATION CONTROL IN MULTI AREA INTERCONNECTED POWER SYSTEM USING PID CONTROLLER BASED ON GA AND PSO

open access: yesDiyala Journal of Engineering Sciences, 2015
The goal of paper is to maintain the frequency and tie line power changes are maintained at their scheduled values, so in this paper presents two methods for determination of the optimal (Proportional-Integral-Derivate) PID parameters for Automatic ...

Introducing electric spring in the voltage frequency regulation of a multi area multi source integrated power system network

open access: yesScientific Reports
The present work demonstrates the application of an electric spring in a multi-source interconnected power system in which coordinated control of frequency and voltage loop is investigated. A two-area power system is considered with non–linearity for the

Exon 7 splicing of ERα predicts poor prognosis and increases phenotypic heterogeneity in luminal a subtype breast cancer

open access: yesFEBS Open Bio, EarlyView.
ERα splice variant ERα∆7 lacks the C‐terminus, and its expression may change phenotypes of breast cancers. Our results showed that ERα∆7 is found in the luminal A subtype, and elevated ERα∆7 levels are linked to improved cell survival with lower proliferation and migration.

A minimum approximate-BER beamforming approach for PSK modulated wireless systems

open access: yes, 2008
A beamforming algorithm is introduced based on the general objective function that approximates the bit error rate for the wireless systems with binary phase shift keying and quadrature phase shift keying modulation schemes.

Screening and epitope characterization of Nidogen‐2‐specific nanobodies

open access: yesFEBS Open Bio, EarlyView.
Camel immunization and phage display were employed to generate high‐affinity VHH nanobodies against Nidogen‐2. After library construction, biopanning, ELISA screening, sequencing, and recombinant expression, selected nanobodies were purified and characterized, leading to the preliminary exploration of a nanobody‐based sandwich ELISA for specific ...

Self-Adaptive Secondary Frequency Regulation Strategy Based on Distributed Model Predictive Control

open access: yesShanghai Jiaotong Daxue xuebao
To address the issues of reduced adaptability of secondary frequency regulation caused by changes in power system parameters, a self-adaptive secondary frequency regulation strategy based on distributed model predictive control (DMPC) is proposed. First,

YlmG1 is localized exclusively to the chloroplast envelope membrane and is involved in preprotein translocation in Arabidopsis thaliana

open access: yesFEBS Open Bio, EarlyView.
Cytosolically synthesized chloroplast preproteins are translocated across the outer and inner envelope membranes through translocons called TOC and TIC, respectively. In green algae and plants, the TIC core is composed of essential membrane proteins, Tic12, Tic20, and Tic214.

Rapid screening of staphylokinase protein variants using an unpurified cell‐free expression system

open access: yesFEBS Open Bio, EarlyView.
An unpurified cell‐free protein synthesis (CFPS) platform enables rapid functional screening of staphylokinase variants. Direct plasminogen‐activation assays performed in microplate format provide real‐time activity readouts, allowing rapid identification and ranking of variants with improved or reduced fibrinolytic activity without protein ...
