Analytical model

This paper explores the application of GeoGebra software to assist teachers and students in lessons on fixed points of families of lines and circles, a relatively complex topic in secondary school geometry that requires logical reasoning and advanced proof skills. GeoGebra, as a visual modeling tool, enables the discovery and proof of fixed points in problems involving families of lines and circles.

In this study, one analytical procedure was established for simultaneous determination based on UV-Vis spectrometry coupled with several multivariate linear regress solved by Python – an open language programme to quantify three antibiotics, including TET, PGP, and CEX, in laboratoryprepared synthetic and pharmaceutical mixtures. This study also provided a universally analytical procedure for determining the three antibiotics in their pharmaceutical forms without the need for optimization for each analyte.

The main objective of this paper is to categorize the available literature (analytical/experimental). The discussion remains descriptive, and the reader is recommended to consult the cited references for specifics on parameters and mathematical models. Three phases were adopted to conduct this literature review: (a) conducting the review, (b) conducting the analysis, and (c) writing up the review.

Thermophysical properties of industrially complex fluids whose composition is always ill-defined are in practice predicted by using thermodynamic models. To ensure the prediction accurately and reliably, a three-step procedure to obtain the properties of these fluids must be validated. The focus of this study is laid on a short review of tools which can be served for each of the three steps.

In this study, a comprehensive database of 146 URM walls was compiled from 26 research groups and employed to evaluate the accuracy of established guidelines, including ASCE 41-17, NZSEE, Eurocode 6, and GB50003. The comparative analysis showed that ASCE 41-17 provided the most accurate predictions with acceptable safety levels, while NZSEE produced more conservative estimates and excelled in predicting diagonal shear failure modes.

This paper investigates flexural behavior and analytical approach for predicting the load and deflection at critical performance points of reinforced concrete (RC) beams strengthened with prestressed carbon fiber-reinforced polymer (CFRP) sheets. A finite element model is developed to simulate the interaction between the RC beam and the CFRP sheets, capturing key aspects such as failure modes, ultimate load, and mechanical behavior across the three phases of failure.

In the multi-dimensional model of data warehouses, data drawn from multiple sources is organized into fact tables and dimension tables. Data cubes pre-compute the aggregations of measurements along combinations of dimensions to speed up the processing of Online Analytical Processing (OLAP) queries. When the underlying fact tables or dimension tables change over time, data cubes need to be incrementally maintained to reflect these changes. In this thesis, we study the problem of incrementally maintaining data cubes under slowly changing dimensions.

In the course of current research the procedure of obtaining of the piecewise linear vibration systems time and frequency responses have been developed. The method is partly analytical and partly numerical and is based on combining of linear solutions of different sections in a cycle of motion. In a row with the method of obtaining of the exact steady state time and frequency response, also it is provided sensitivity analysis of the vibration isolator.

Modelling the diffusion of mobile commerce in a country is a difficult task due to the non-linear, complex and uncertain nature of its operating environment. Conventional analytical techniques are of limited use in this context, and a System Dynamics approach is more appropriate to model such a complex system.
