This paper presents the concept and architecture of a fatigue damage control system for mechanical structures. In contrast to the conventional cycle-based approach, fatigue damage is represented via non-linear differential equations with respect to time in the state-variable setting. This damage model is compatible with the dynamic model of the plant, i.e. the process under operation and contro...

INTRODUCTION AND AIMS Anticoagulation control as assessed by time in therapeutic range (TTR) correlates positively with the safety and efficacy of thromboprophylaxis in atrial fibrillation. We set out to assess TTR in our unit and to investigate determinants of better control. METHODS This was a case series study of atrial fibrillation patients anticoagulated with warfarin or acenocoumarol at...

The following article, submitted in two complementary parts deals with an important and also modern concept developed under the name of damage-control surgery. Physiopathologically, the multiple injured patient is characterised by the probable, not just possible, appearance of the "blood's vicious cycle" of hypocoagulability, hypothermia and acidosis with death as a result. The first part of th...

In a recent issue of this JournuZ, Richard 0. Zerbe [7] considered the effects of alternative assignments of liability for damage in the field of pollution control and presented a useful categorization and analysis of alternative methods of achieving any particular level of control. In the process, Zerbe makes some rather strong claims for the “Coase theorem” which deserve further discussion. F...

Objective(s):Ischemia is described as organs and tissues are destitute of oxygen due to decreased arterial or venous blood flow. Many mechanisms play role in cell death happened as a consequence of a new blood flow is needed for both cell regeneration and to clean toxic metabolites during ischemia and later. Lung damage induced by ischemia/reperfusion (I/R) is a frequent problem in lung transpl...

| We propose an optimization approach to ow control where the objective is to maximize the aggregate source utility over their transmission rates. We view network links and sources as processors of a distributed computation system to solve the dual problem using gradient projection algorithm. In this system sources select transmission rates that maximize their own beneets, utility minus bandwid...

With the rapid growth of Web 2.0 technologies, users are contributing more and more content on the Internet, in the form of user profiles, blogs, reviews, etc. With this increased sharing comes a pressing need for access control policies and mechanisms to protect the users’ privacy. Access control has remained largely centralized and under the control of the web applications hosted on their ser...

Binary tree classification has been useful for classifying the whole population based on the levels of outcome variable that is associated with chosen predictors. Often we start a classification with a large number of candidate predictors, and each predictor takes a number of different cutoff values. Because of these types of multiplicity, binary tree classification method is subject to severe ...

In this first part of our paper, we introduce some basic concepts and terminology of distributed planning, and describe a novel CoordinatorCoworker structure — a control mechanism that can dynamically reorganize the planning system in response to the tasks at hand. Coordinators get either self-appointed in unambiguous situations or selected through a unique and inexpensive nomination/confirmati...

This paper presents a framework for plot control in interactive story systems. In this framework, the user takes the place of the main character of the story, the protagonist. The rest of the cast consists of discrete characters, each playing a specific role in the story. A separate module in this system, the plot manager, controls the behavior of the cast and specifies what the protagonist can...
