Gradient remediability in linear distributed parabolic systems analysis, approximations and simulations

The aim of this paper is the introduction of a new concept that concerned the analysis of a large class of distributed parabolic systems. It is the general concept of gradient remediability. More precisely, we study with respect to the gradient observation, the existence of an input operator (gradient efficient actuators) ensuring the compensation of known or unknown disturbances acting on the considered system. Then, we introduce and we characterize the notions of exact and weak gradient remediability and their relationship with the notions of exact and weak gradient controllability. Main properties concerning the notion of gradient efficient actuators are considered. The minimum energy problem is studies, and we show how to find the optimal control, which compensates the disturbance of the system. Approximations and numerical simulations are also presented.Keywords: actuators efficient; disturbance; gradient; parabolic systems; remediability; sensor

Regionally Gradient Efficient actuators and Sensors

In this paper, we introduce and characterize the notions of regional gradient remediability and regionally gradient efficient actuators. We study their relationship with regional gradient controllability and sensors. As an application, we consider the case where the domain is one and two dimension. nbs

Cloud privacy and security issues beyond technology: championing the cause of accountability

Cloud computing provides IT service providers increased efficiency of resource utilization while enabling consumers to benefit from innovative advantages like access to up-to-date IT resources and low upfront investment. A significant hindrance to adoption of cloud computing is the lack of trust arising from worries over privacy and security when data resources of cloud service consumers are handled by third parties. A key factor in fostering cloud privacy and security is accountability, which increases trust by obligating an entity to be answerable for its actions. This paper uses a hermeneutic literature review to investigate (i) the prevailing methods and strategies of fostering privacy and security through accountability, (ii) the key actors in championing cloud accountability and (iii) the key barriers to cloud accountability. This literature review provides insight into current practices associated with championing cloud accountability and contributes to cloud service provider awareness of ways to improve cloud computing trustworthiness

Rhetorical Resolutions to the Tension Between Issue Ownership and Agency OR What do you do with an old social movement?

This paper will apply Gusfield’s theory of issue ownership to one specific social issue: domestic violence. It will briefly trace the evolution of the issue as a social problem, looking at the battered women’s movement. It will present a case study of a specific, localized issue owner – Boulder County Safehouse, now SPAN (Safehouse Progressive Alliance for Nonviolence) as it attempts to reframe the problem and expand its control of the issue. Finally, the case study and paper will serve as an exemplar for how other issue owners might meet the challenge of expanding the power of ownership to reframe an issue -- to keep it current and viable

The medical aspects of personal injury assessment

The doctor who writes the report on injury cases should be a specialist in this very specific field of medico-legal science, with considerable experience. In this article the author describes how such a doctor assesses and reports an injured individual.peer-reviewe
