 Free Download Filippo Furfaro, Francesco Parisi, "Repairing and Querying Databases under Aggregate Constraints" English | 2011 | pages: 66 | ISBN: 146141640X | PDF | 1,0 mb Research has deeply investigated several issues related to the use of integrity constraints on relational databases. In particular, a great deal of attention has been devoted to the problem of extracting "reliable" information from databases containing pieces of information inconsistent with regard to some integrity constraints. In this manuscript, the problem of extracting consistent information from relational databases violating integrity constraints on numerical data is addressed. Aggregate constraints defined as linear inequalities on aggregate-sum queries on input data are considered. The notion of repair as consistent set of updates at attribute-value level is exploited, and the characterization of several data-complexity issues related to repairing data and computing consistent query answers is provided. Moreover, a method for computing "reasonable" repairs of inconsistent numerical databases is introduced, for a restricted but expressive class of aggregate constraints. An extension of this method for dealing with the data repairing problem in the presence of weak aggregate constraints which are expected to be satisfied, but not required to, is presented. Furthermore, a technique for computing consistent answers of aggregate queries in the presence of a wide form of aggregate constraints is provided. Finally, extensions of the framework as well as several open problems are discussed.  Free Download Walmor C. DeMello, Edward D. Frohlich, "Renin Angiotensin System and Cardiovascular Disease" English | 2009 | pages: 249 | ISBN: 1607611856, 1617796387 | PDF | 4,6 mb Experimental and clinical evidence supports the view that the activation of the renin angiotensin aldosterone system is involved in cardiovascular pathology including hypertension, heart failure, myocardial ischemia, and atherosclerosis. The present volume describes the intricacies involved in these processes, including the in?uence of prorenin/renin, angiotensin II, angiotensin (1-7), and aldosterone on cardiac and vascular functions as well as their involvement in the generation of cardiovascular diseases. Fundamental aspects like intracellular signaling, regulation of cell volume in the failing heart, and the presence of an intracrine renin angiotensin system are discussed. Moreover, the role of the mineralocorticoid receptor as an important c- ponent of the intracrine renin angiotensin system and as a regulator of extracellular action of angiotensin II is described, reinforcing the view that aldosterone inhibitors are helpful in the treatment of heart failure and hypertension. Let us hope the imp- tant topics included here motivate basic and clinical investigators and contribute to the development of new therapeutic approaches for cardiovascular diseases. We want to thank the distinguished authors and Humana Press for the opportunity to publish this important book. Walmor C.

This book develops a concept and a theory of reluctance in world politics. Applying it to the study of regional crisis management by leading powers, it finds that reluctance emerges when governments fail to devise clear foreign policy preferences and face competing international pressures. The study of reluctance in world politics sheds new light on some of the most pressing problems of our time, from weak crisis management to cooperation deficits in global governance.

Shin, Rex Gantenbein, Tei-Wei Kuo, "Reliable and Autonomous Computational Science" English | 2010 | pages: 416 | ISBN: 3034800304 | PDF | 16,8 mb Increasing size and complexity of software and hardware systems makes it harder to ensure their reliability. At the same time, the issues of autonomous computing become more critical as we more and more rely on software systems in our daily life. Such complexity is getting even more critical with the ubiquitous computing of embedded devices and other pervasive systems. These trends ask for techniques and tools for developing reliable and autonomous software which can support software engineers in their efforts. This book summarizes the state of the art of research in the diverse fields concerned, including novel designs, case studies and experimental as well as theoretical results.
