THE DETERMINATION OF THE STATISTICAL PARAMETERS OF THE CONVERTERS IN CIRCUITS TEST STANDS FOR TRACTION MOTORS OF THE LOCOMOTIVE

Nauka ta progres transportu, 2008
In the article the method of static converters parameters calculation is resulted. It is proposed to replace the electromachine linear generator and balancing booster with static converters in the scheme of the traditional stand for test of locomotives ...

Improvements in Bidirectional Power-Flow Balancing and Electric Power Quality of a Microgrid with Unbalanced Distributed Generators and Loads by Using Shunt Compensators

Energies, 2018
Improper connections of unbalanced distributed generators (DGs) and loads in a three-phase microgrid cause unbalanced and bidirectional power flow problems. The unbalanced DGs and loads may also aggravate the electric power quality (EPQ), such as voltage

Design Considerations for 3RRR Parallel Robots with Lightweight, Approximate Static-Balancing

, 2023
Balancing parallel robots throughout their workspace while avoiding the use of balancing masses and respecting design practicality constraints is difficult. Medical robots demand such compact and lightweight designs.

Iron homeostasis disruption and lipid peroxidation in skeletal muscle during short‐term immobilization

FEBS Open Bio, EarlyView.
14‐day casting‐induced immobilization reduced gastrocnemius muscle mass and increased non‐heme iron and ferritin heavy chain levels. Despite iron accumulation, transferrin receptor 1 and iron regulatory protein 2 were paradoxically upregulated. Lipid peroxidation was elevated without compensatory antioxidant responses.

Research of Static-couple Separation Swing Frame on the Fixed Vibration Center

工程科学与技术, 2019
Owing to the structure of the swing frame, the vibration center of the traditional two-plane vertical balancing machine is fluctuated, which often leads to the large error on measurement and the poor effect for static-couple separation.

Performance tradeoffs in static and dynamic load balancing strategies

, 1986
The problem of uniformly distributing the load of a parallel program over a multiprocessor system was considered. A program was analyzed whose structure permits the computation of the optimal static solution.

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

FEBS 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 ...

Systemic dysregulation of apolipoproteins in amyotrophic lateral sclerosis serum

FEBS Open Bio, EarlyView.
Amyotrophic lateral sclerosis (ALS) is a fatal disease that damages motor neurons. This study found that people with ALS show significant changes in blood fats and the proteins that carry them. Several apolipoproteins were higher, lipid balances were altered, and normal protein–lipid relationships were disrupted.
