Reproducing Kernel Method For Solving Fuzzy Initial Value Problems, Qamar Kamel Dallashi Feb 2022

Reproducing Kernel Method For Solving Fuzzy Initial Value Problems, Qamar Kamel Dallashi

Theses

In this thesis, numerical solution of the fuzzy initial value problem will be investigated based on the reproducing kernel method. Problems of this type are either difficult to solve or impossible, in some cases, since they will produce a complicated optimized problem. To overcome this challenge, reproducing kernel method will be modified to solve this type of problems. Theoretical and numerical results will be presented to show the efficiency of the proposed method.


Technology-Intensive Exports, R&D, Human Capital, And Economic Growth In The Twenty-First Century, Pierce Plucker Jan 2022

Technology-Intensive Exports, R&D, Human Capital, And Economic Growth In The Twenty-First Century, Pierce Plucker

Electronic Theses and Dissertations

This thesis investigates twenty-first century economic growth through a distanceto- frontier (technology-gap) lens where growth in a country’s knowledge stock is determined by knowledge creation and knowledge imitation. The creation term is assumed to be a function of research and development, technology-intensive export performance, and human capital, while the imitation term is a function of the technology gap, technology-intensive export performance, and human capital. Over the period 1997-2018, two samples of countries are analyzed in a panel setting, and two growth models are estimated in total—one for each sample. While research and development has been extensively analyzed in the economic …
