Determining the waveguide conductivity in a hyperbolic equation from a single measurement on the lateral boundary

We consider the multidimensional inverse problem of determining the conductivity coefficient of a hyperbolic equation in an infinite cylindrical domain, from a single boundary observation of the solution. We prove H{\"o}lder stability with the aid of a Carleman estimate specifically designed for hyperbolic waveguides

The Echo of a Century: Coleridge’s Perception of Nature in The Rime of the Ancient Mariner and Modern Ecological Studies

This thesis analyzes the relationship between man and nature as portrayed in Samuel Taylor Coleridge’s The Rime of the Ancient Mariner. In the narrative poem, his unique views on Nature present a remote echo to today’s ecological concerns and scientific efforts to improve our ecosystem. The current study explores the implied ideas of Coleridge’s poetical manifestation and contemporary activists’ environmental consciousness so as to join the increasingly important discussion of how human beings adapt a reasonable pace to relieve some of the unbearable burden they have exerted on the Earth at an unprecedented speed and in a large scale. Such analytic attempts focus mainly on the critical connection between natural ecology and spiritual ecology. When understanding sustainable development at both the natural and spiritual levels, mankind may find real motivations to respect and protect Nature, and live in harmony with Nature.

University Success Oral Communication

A book review presented in this essay suggests that teacher-centered oral communication is not the only—nor is it an essential—means for helping students develop a sense of critical consciousness in oral communication. Utilizing Murphy’s theory—Listening and speaking abilities are an indispensable aspect of second language proficiency, I point out the importance of his book in the introduction part. Outlined the second part is the organization and comments on this book. In the third part of the book’s disadvantages and advantages are highlighted.
