TRANSMISSION NETWORK LOSS MINIMIZATION USING ARTIFICIAL NEURAL NETWORK AND FACTS DEVICES
, 2022 : Due to the increase in voltage instability problem and power losses in Nigeria grid are a serious operational challenger facing electricity supply utilities. The Nigeria 330Kv power grid was used as a case study for the evaluation of the proposed power

Transmission loss allocation through a modified Ybus
, 2005 A methodology to allocate the active power transmission loss among agents of a power pool is proposed. The approach is based on the inclusion of the admittances equivalent to bus power injections in the bus admittance matrix.

Local model of plane acoustic waves propagation in multilayered infinite sandwich structures
Archives of Mechanics, 2011 A local model for computing the coincidence frequencies and the transmission loss of multilayered infinite sandwich plates composed of isotropic layers is presented in the paper. The model is derived within the local theory of linear elastodynamics under

Gut microbiome and aging—A dynamic interplay of microbes, metabolites, and the immune system
FEBS Letters, EarlyView.Age‐dependent shifts in microbial communities engender shifts in microbial metabolite profiles. These in turn drive shifts in barrier surface permeability of the gut and brain and induce immune activation. When paired with preexisting age‐related chronic inflammation this increases the risk of neuroinflammation and neurodegenerative diseases.

Study on Nature Fiber Composite for Noise Material Control
International Journal of TechnologyTransportation tracks of railways and highways are the highest noise pollution contribution to the inhabitant urban due to the sources near residential areas. Many researchers proved that the composite material could help reduce the noise by 30%. This

From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Design and Testing of a Gasoline Engine Muffler Based on the Principle of Split-Stream Rushing
Applied SciencesIn order to reduce the exhaust noise, which is the main source of gasoline engine noise, this paper uses on orthogonal test to optimize the parameters of the main structure of split-stream rushing muffler (the perforation rate of the perforated pipe ...
