Liberalized competitive electrical energy markets need tools for realtime stability assessment to link the technical with the market issues. Analytical tools are available but time-consuming. Alternatively, knowledge based systems speed up the stability assessment but most of them need extensive and assessed training data. Unsupervised learning methods like Growing Neural Gas or SelfOrganizing ...

Legacy conferences are costly and time consuming, exclude scientists lacking various resources or abilities. During the 2020 pandemic, we created an online conference platform, Neuromatch Conferences (NMC), aimed at developing technological cultural changes to make more democratic, scalable, accessible. We discuss lessons learned.

Cation exchange capacity (CEC) is one of the important indices in soil fertility. Direct measurement of CEC is time consuming and expensive, especially in aridisols containing high amounts of carbonates and gypsum. Alternatively, CEC could be indirectly predicted through pedotransfer functions (PTF). The objective of this study was to predict CEC using class and continuous PTFs.A data set (n = ...

soil hydraulic properties such as saturated and unsaturated hydraulic conductivity play an important role in environmental research. since direct measurement of these soil hydraulic properties is time-consuming and costly, indirect methods such as pedotransfer functions and artificial neural networks (ann) were developed based on readily available parameters. in this study, the use of ann to pr...

Background and purpose: Congenital Myasthenic Syndrome (CMS) is a rare genetic disease with autosomal recessive inheritance pattern which is caused by mutations in the COLQ gene. Molecular diagnosis of the disease using direct mutation analysis is expensive and time consuming. Alternatively, linkage analysis using Single Nucleotide Polymorphic markers (SNP) provides a suitable method in carrier...

The development of therapeutics is costly, time-consuming and has high attrition rates. Biopharmaceutical medications differ from traditional agents in their discovery, design, structure and formulation. Prior to marketing a drug must show efficacy and acceptable toxicity in both preclinical and clinical trials. Regulatory bodies have a pivotal role in the licensing, naming and marketing of an ...
