Ever since Rick Shull asked me to prepare an essay of appreciation of Fred Keller, I have found myself putting it off. Somehow, something else was always needing to be done. Finally, I realized what was happening. I just did not want to face the fact that Fred was no longer with us. After a relationship that extended over more than 50 years, during which Fred taught me both pedagogically and by...

I design and build secure and reliable networked systems using a cross-layer approach that draws from networking, operating systems, distributed systems, and computer architecture. My focus is on virtualization and the movement toward cloud-based services. Rather than simply patching existing systems, I question the underlying assumptions to create new designs that are fundamentally more secure...

Zusammenfassung Bei der Identifizierung einer unbekannten, stark verwesten Leiche oder eines Skelettes ohne Hinweise auf die Identität durch Auffindesituation spielt Erstellung des sog. biologischen Profils eine entscheidende Rolle. Vorgestellt wird ein Leichenfund in einem mehr weniger frei zugänglichen Kellerabteil Mehrfamilienhauses. Der Leichnam war weitgehend skelettiert, das Skelett jedoc...

This article is centered around generalizing a previous implicit function theorem of the author to be applicable for maps f : E⊓F → F which can be lifted to Keller C π –maps fi : E ⊓ Fi → Fi with Fi Banach and F = proj limFi . We prove theorems about existence and differentiability of functions g satisfying f (x, g (x)) = b constant. In addition to these abstract theorems, we give several examp...

An analytical model is developed to study the viscoelastic micropolar fluid convection from an inclined plate as a simulation of electro-conductive polymer materials processing with nonlinear temperature. Jeffery’s viscoelastic model is deployed to describe the non-Newtonian characteristics of the fluid and provides a good approximation for polymers. Micro-structural is one of the characteristi...

The current research study is focusing on a mathematical model for free convection boundary flow horizontal circular cylinder in viscoelastic nanofluid has been constructed this paper with conditions constant heat flux. Tiwari and Das Nanofluid have chosen analysis to investigate more effects. A dimensionless set of partial differential equations formed by using suitable non-dimensional variabl...

The hybrid materials are an impressive class of nanofluids with exciting thermal outcomes and present applications in enhancing the heat transfer procedure, solar energy, extrusion processes, different engineering processes. current contribution aims to reflect improved mechanism phenomenon for nanofluids. Aluminum oxide, copper, copper oxide at solid volume fractions used report phenomenon. Fo...
