The task scheduling of real-time tasks request is an important component of survivability system. In survivability system, how to schedule real-time tasks to meet the needs of various services at different levels is one of the important topics in survivability research. A task scheduling algorithm is proposed based on optimization decision theory of variable fuzzy set, which apply optimization ...

The ability of a network to continue functioning even after the occurrence of any failure is very much required in optical networks. As optical networks are capable of transmitting a large amount of data at very high speed, so any failure or breakdown even for small duration can cause significant data and revenue loss. So the survivability of optical networks has become very important issue for...

Prediction of cancer survivability using machine learning techniques has become a popular approach in recent years. ‎In this regard, an important issue is that preparation of some features may need conducting difficult and costly experiments while these features have less significant impacts on the final decision and can be ignored from the feature set‎. ‎Therefore‎, ‎developing a machine for p...

The notion of a part of phase space containing desired (or allowed) states of a dynamical system is important in a wide range of complex systems research. It has been called the safe operating space, the viability kernel or the sunny region. In this paper we define the notion of survivability: Given a random initial condition, what is the likelihood that the transient behaviour of a determinist...

This paper deals with problems of computer networks survivability. We present and discuss survivability aspects of Content Delivery Networks (CDNs) and other services based on the anycast paradigm. After that, we propose a new unified approach to network survivability. This approach assumes using jointly survivability mechanisms for both kinds of traffic: anycast (oneto-one-of-many access to co...

As more and more traffic is transported over communication networks, network survivability becomes a key issue in network design and planning. In this paper first the need for deploying network recovery techniques at multiple layers is motivated. Then the efficient coordination of these network recovery techniques is studied. Not only static but also dynamic multi-layer survivability strategies...

This research focuses on the performance and timing behavior of a two level survivability architecture. The lower level of the architecture involves attack analysis based on kernel attack signatures and survivability handlers. Higher level survivability mechanisms are implemented using migratory autonomous agents. The potential for fast response to, and recovery from, malicious attacks is the m...

BACKGROUND & OBJECTIVES Bio-manipulation technique is of primary importance during the development of transgenic mosquitoes. The study describes the variable factors that influence the viability of medically important mosquito vectors during microinjection. METHODS Three mosquito vectors belonging to the genus Aedes, Anopheles and Culex were microinjected at different developmental stages of ...

In the Next Generation Internet security will be a cumulative, distributed, and probabilistic. The approach to security as survivability reflects the need of a Next Generation Internet where robustness must compensate for lack of hardening; and denial of service or disconnection are not acceptable defense mechanisms. In sum, the Next Generation Internet has to have survivability as a whole, as ...
