A 63-year-old man bearing most signs and symptoms (facial pigmentation, degenerative arthritis, and dark urine) pertinent to his known history of alkaptonuria underwent aortic valve replacement for critical aortic stenosis. Although rare, aortic stenosis is the most common cardiac manifestation of alkaptonuric ochronosis.

The paper aims at providing a complete survey of contemporary distributed systems of that time. The authors define a distributed operating system distinguishing it from networked systems. The paper endeavours to also explain in detail the key design issues involved in the building of such systems. A few examples of research projects are considered in light of the issues discussed. A distributed...

This paper gives an overview of educational operating system called COLIBROS. It is small, object oriented, library operating system, based on micro-kernel concepts, supporting high level concurrency and synchronization primitives. In fact, COLIBROS is simplified operating system kernel accompanied with hardware emulation layer that emulates keyboard, monitor, disk and interrupt mechanism. A co...

An operating system is a fundamental component of most modern computer systems, Operating systems are close to the hardware, it masks the details of the underlying hardware from the programmer and provides lowest layer of software visible to users. It can be viewed as a resource manager, responsible for fair resource sharing between different processes in the system. On the other hand, Operatin...

Realizing elasticity in cloud applications today is often a cumbersome process, requiring applications to integrate with services like elastic load balancers and/or be rewritten to accommodate distributed frameworks like map/reduce or cluster-based operating systems. In this paper, we introduce the concept of ElasticOS, which enables a process (or even a single thread) to stretch its associated...
