Evidence for the utility of quantum computing before fault tolerance

Abstract Quantum computing promises to offer substantial speed-ups over its classical counterpart for certain problems. However, the greatest impediment to realizing its full potential is noise that is inherent to these systems. The widely ...

A Calculus for Access Control in Distributed Systems

The Breakdown of Coordinated Decision Making in Distributed Systems

OBJECTIVE: This article aims to explore the nature and resolution of breakdowns in coordinated decision making in distributed safety-critical systems. BACKGROUND: In safety-critical domains, people with different roles and responsibilities ...

Sensors and Controls in the Analysis of Distributed Systems

The object of this book is to present the principal results in the analysis of distributed parameter systems, which are concerned with the structure of input-output operators, i.e. actuators and sensors.We have adopted an approach via semig...

Optimal Control of Spatially Distributed Systems

In this paper, we study the structural properties of optimal control of spatially distributed systems. Such systems consist of an infinite collection of possibly heterogeneous linear control systems that are spatially interconnected via cer...

Dynamics and Control of Distributed Systems

Distributed parameter systems encompass a broad range of engineering applications from stereo speakers to space structures. The dynamic behaviour of these systems is usually governed by one or more partial differential equations, which may ...

Distributed Systems

Distributed applications consist of a collection of heterogeneous but fully autonomous components that can execute on different computers. While each of these components has full control over its constituent subparts, there is no master com...

A policy framework for management of distributed systems

Policy-based management is one of the latest developments in network and distributed systems management. Academic and commercial settings, as well as standardisation bodies are concentrating on policy-based management as a very promising so...

Functionally Accurate, Cooperative Distributed Systems

A new approach for structuring distributed processing systems, called functionally accurate, cooperative (FA/C), is proposed. The approach differs from conventional ones in its emphasis on handling distribution-caused uncertainty and errors...

Dynamic Thermal Management for Distributed Systems

In modern data centers, the impact on the thermal properties by increased scale and power densities is enormous and poses new challenges on the designers of both computing as well as cooling systems. Controltheoretic techniques have proven ...

A Formal Composition of a Distributed System Formal Composition of a Distributed System Formal Composition of a Distributed System Formal Composition of a Distributed System

Nowadays, information systems are becoming a vital and st rategic component of any organization. However, in most cases, these systems are designed and implemented without taking into consideration aspects. To ensure a certain level of secu...

DISTRIBUTED SYSTEM-A TOOL FOR BUILDING DEPENDABLE DISTRIBUTED SYSTEM

Physically, a Distributed System consists of a set of processors, with a collection of local storage mechanisms associated with each processor. A processor is able to execute programs that access and manipulate the local storage, where the ...

Distributed Systems

This chapter provides an introduction to distributed computing as a foundation for better understanding of cloud-enabled business processes. Distributed systems constitute of a large umbrella under which several different software systems a...

On the controllability of distributed systems

To "control" a system is to make it behave (hopefully) according to our "wishes," in a way compatible with safety and ethics, at the least possible cost. The systems considered here are distributed-i.e., governed (modeled) by partial differ...

1. Pointwise Control for Distributed Systems

1.1. Introduction. We consider in this chapter systems modeled by Partial Differential Equations of evolution, i.e., evolution distributed systems. We suppose that we can act on the system only at some particular points, this is the so-call...

Synchronization and control of distributed systems and programs

Part 1 Different forms of synchronization between processes: distributed systems, networks, and networks of processes synchronization. Part 2 The concept of a wave, and synchronization by wave train: wave algorithms example of use - computa...

Safety and reliability driven task allocation in distributed systems

Distributed computer systems are increasingly being employed for critical applications, such as aircraft control, industrial process control, and banking systems. Maximizing performance has been the conventional objective in the allocation ...

The Digital Distributed System Security Architecture

The Digital Distributed System Security Architecture is a comprehensive specification for security in a distributed system that employs state-of-the-art concepts to address the needs of both commercial and government environments. The archi...

The complexity of sorting on distributed systems

Conflicts in policy-based distributed systems management

Modern distributed systems contain a large number of objects and must be capable of evolving, without shutting down the complete system, to cater for changing requirements. There is a need for distributed, automated management agents whose ...
