Improvement Of Calorimetric Quality Analyzers For Substances, Makhfuza Azimovna Radjabova Dec 2023

Improvement Of Calorimetric Quality Analyzers For Substances, Makhfuza Azimovna Radjabova

Chemical Technology, Control and Management

It is noted that the development of intelligent means of measuring qualitative indices is of topical importance. Since the quality of many substances is determined by optical methods, an algorithm for spectrophotometric data processing has been developed, which consists of primary data processing (stage I) and determination of qualitative indices of liquid products (stage II). Since the task of numerical determination of colour characteristics of transmittance coefficients of liquid samples is incorrectly set, it is recommended to use regularization methods of A.N.Tikhonov to improve metrological characteristics of the device.

The Power Of Eponyms: Exploring Cultural And Social Factors In Their Adoption And Popularization, Sawsan A. Qasim Dec 2023

The Power Of Eponyms: Exploring Cultural And Social Factors In Their Adoption And Popularization, Sawsan A. Qasim

Uruk Journal of Human Sciences

The aim of this article is to investigate eponyms, which are not just linguistic phenomena but also cultural since they demonstrate one's influence on society and history. Words formed from a person's name, such as "volt" from Alessandro Volta and "sandwich" from John Montagu, 4th Earl of Sandwich, are examples of eponyms. Eponyms can be used to honor prominent persons, such as scientists, innovators, or well-known figures. They also demonstrate how society prioritizes specific accomplishments or attributes, as in the situations of “Fahrenheit” and “Celsius,” which are named after two pioneering scientists in the field of temperature measurement. Eponyms may …

Genome-Wide Search Algorithms For Identifying Dynamic Gene Co-Expression Via Bayesian Variable Selection, Wenda Zhang, Zichen Ma, Lianming Wang, Daping Fan, Yen Yi Ho

Faculty Publications

A wealth of gene expression data generated by high-throughput techniques provides exciting opportunities for studying gene-gene interactions systematically. Gene-gene interactions in a biological system are tightly regulated and are often highly dynamic. The interactions can change flexibly under various internal cellular signals or external stimuli. Previous studies have developed statistical methods to examine these dynamic changes in gene-gene interactions. However, due to the massive number of possible gene combinations that need to be considered in a typical genomic dataset, intensive computation is a common challenge for exploring gene-gene interactions. On the other hand, oftentimes only a small proportion of gene …

Argumentation Practice In Engineering Design Process, Tharuesean Prasoplarb, Pongprapan Pongsophon, Ekgapoom Jantarakantee, Chatree Faikhamta

Journal of Education Studies

Argumentation practice is consisted in science and engineering practices (SEPs) that play a crucial role in shifting science education from “knowing science” to “doing science” while also challenging the learner to solve real-world problems. However, teaching argumentation practice in science classrooms has become a challenge for teachers in regard to distinguishing argumentation from constructing scientific explanations, understanding the nature of argumentation, and embedding argumentation in STEM to a more authentic context. This article aims to draw the teaching of argumentation practice with the engineering design process through investigating the ecology of engineering features synthesized from the nature of engineering, nature …

Financial Contagion And Financial Lockdowns, Gabriele Camera, Alessandro Gioffré Dec 2023

Financial Contagion And Financial Lockdowns, Gabriele Camera, Alessandro Gioffré

ESI Working Papers

Extreme financial shocks often elicit extraordinary policy interventions that preclude financial activity on a large scale, for example as the 1933 U.S. “bank holiday.” We study these interventions using a random matching framework where the financial contagion process is explicit and the diffusion of the initial shock can be analytically characterized. The study suggests that there is scope for forced closures of individual firms or even economy-wide financial lockdowns only when firms are financially vulnerable and policy institutions are not well-functioning. Here, ordinary policy alone cannot prevent or sufficiently mitigate contagion, while complementing it with a lockdown or individual closures …
