  • In the course of researching and writing this book, I have been blessed with abundant help. Arthur McEvoy has been a personal and scholarly model for more than a decade, and it is to him that I owe the greatest thanks for anything that is creative in this project. Whenever recommending one of his favorite books or his foolproof model for writing, he often promised me, “This will change your life.” My studies with him did.

  • Some studies are content with establishing simple correlations, while others involve sophisticated econometric analysis, attempting to ascertain the existence and direction of causality. Yet other studies involve complex systems with feedback loops or large simulation models with scenario analysis. Inevitably, they reach different conclusions even when they analyze the same body of data because of differences in perspectives, levels of aggregation and methods of analysis.

  • There are many methods to design digital circuits without hazard, such as the use of Boolean algebra, algebra hazard, karnaugh map, matrix method, VHDL, etc. However, these methods are not very suitable for the design of circuit system such as design of GALS circuits. In this case, synchronization is the most optimal method. 1. Introduction Hazard is the essence of digital circuits including synchronous circuit and asynchronous circuit. Hazard occurs as much as “autumn’s leaves” [1] and has adverse impact on the working of digital circuits. ...

  • Migration and remittances patterns in Nicaragua are also worth noting. Migration from Nicaragua is predominantly to Costa Rica and the United States. In a nationwide study conducted in June 2001, 42 per cent of those living in Managua reported having a relative abroad, compared to 35 per cent in the Pacific region and 29 per cent from North-Central Nicaragua. The majority of those reporting outside Managua had relatives working in Costa Rica, whereas those living in Managua had relatives primarily migrating to the United States (Orozco, 2003).

  • Under the name of ideal circuit network, it is easy to make us understand that digital circuits are independent of the inner status and their outputs just only depend on the inputs. They are time constants and therefore Boolean algebra is a special suitable means of describing. In fact propagation delay time of circuit system should be in thought firstly in designing circuit network. In that case Boolean algebra does not seems to be fully suitable for describing actual circuit systems.

  • It is not easy to point out Hazards and Deadlock in a circuit with a complex structure. Determination methods for Hazard, Race, Deadlock in [1-3] cannot be applied to this case. With complex circuit structure, specific solution must be offered for each circuit type such as solution of synchonization for asynchronous circuits [4]. GALS circuit is a complex circuit system; thus, the above-mentioned solution is also applied to this circuit. 1. Introduction GALS (Global Asynchronous - Local Synchronous) is a combined system.

  • Theoretical study of earthquakes as well as practical application is actually important to determine the earthquake hazard assessment and risk in a specific region. This is probably the most important contribution of seismology to society. recent earthquake showed the inadequacy of a large part of the building construction in and around the epicentral area, so the study of earthquakes has become and more important.

  • The mitigation of earthquake-related hazards represents a key role in the modern society. The mitigation of such kind of hazards spans from detailed studies on seismicity, evaluation of site effects, and seismo-induced landslides, tsunamis as well as and the design and analysis of structures to resist such actions. The study of earthquakes ties together science, technology and expertise in infrastructure and engineering in an effort to minimize human and material losses when they inevitably occur.

  • It is hard to imagine that less than fifteen years ago building and fire codes specific to the construction of a wafer fabrication facility were just in the process of being developed. Detection and evaluation of leaking underground storage tanks and epidemiological health studies aimed at qualifying and quantifying our “cleanroom” image were in their infancy stages and Cal- OSHA had just completed the first in-depth study of the industry’s chemical processes and associated industrial hygiene exposures....

  • This study of a large, nationally representative sample of Australian women who had recently given birth provides the first examination of consultancy patterns across conventional maternity care providers and CAM practitioners during pregnancy. The study presents four key findings. First, the study reveals a substantial level of CAM practitioner use with nearly half of the pregnant women consulting a CAM practitioner concurrent to conventional maternity care.

  • Climate change is happening now. Climate-induced disasters are occurring in the Asia Pacific region, where a distinctly increasing trend has been observed in recent decades. This shows that the region is the most disaster prone, compared with other parts of the world. Studies on the causes of disaster in many affected regions suggest that in a typical disaster, cities with high population density see increases in mortality and number of people affected. Increased economic losses within the region are also inevitable.

  • Skylines, and other directly related problems such as multiobjective opti- mization [Steuer 1986], maximum vectors [Kung et al. 1975; Matousek 1991], and the contour problem [McLain 1974], have been extensively studied and nu- merous algorithms have been proposed formain-memory processing. To the best of our knowledge, however, the first work addressing skylines in the context of databaseswasBorzsonyi et al.

  • Mangroves play an important role in coastal zones in many aspects e.g. extremely essential habitats for many species, coastlines protection from natural hazards, and so on. However, in Vietnam, like in other developing countries, these mangrove areas have been destroyed and encroached as a consequence of a poorly planned economic development. The study has been conducted in Phu Long - Gia Luan region, which have the largest mangrove area in the Cat Ba Archipelago Biosphere Reserve, Hai Phong City, Vietnam. The aims of the study are to investigate existing land...

  • Normally the frequency divider designed by Boole algebra and to design a frequency divider with any divide factor, we have to repeat all over again every design step as the same. So to avoid of wasting time and money, instead of using traditional Boole algebra in digital technical we replace it by mathematical models in high algebra. And because of that we can design frequency dividers use computer. 1. Modeling of function circuit

  • This paper considers the case for mortgage covered bonds as an alternative to the originate- to-distribute mortgage funding model. It argues that the economic incentives provided to market participants under the covered bonds model are less susceptible to moral hazard even while retaining the key benefits of securitization such as capital market funding and flexibility in risk allocation.
