High complexity of phenomena

School transportation (ST) crashes are associated with serious adverse consequences, particularly for students in developing countries. High-risk behaviors (HRBs) of ST drivers are a major factor contributing to ST crashes. This study aimed at exploring the facilitators and barriers to HRBs among ST drivers.

Dynamical models of gene regulatory networks (GRNs) are highly effective in describing complex biological phenomena and processes, such as cell differentiation and cancer development. Yet, the topological and functional characterization of real GRNs is often still partial and an exhaustive picture of their functioning is missing.

In the field of severe accident, the description of corium progression events is mainly carried out by using integral calculation codes. However, these tools are usually based on bounding assumptions because of high complexity of phenomena.

Hydrological modelling is a powerful technique of hydrologic system investigation for both the research hydrologists and the practicing water resources engineers involved in the planning and development of integrated approach for management of water resources. In present study, the observed rainfall and runoff data of 2010, 2011, 2013 and 2014years were used as input data. In ANN, input data was divided in 70 per cent, 15 per cent and 15 per cent for training, testing and validation purpose, respectively.

Specific writing prompts administered during testing are developed with the assistance of external prompt writers who are recruited on the basis of their expertise and to reflect the diversity of the populations served by the ACT. ACT prompt writers are male and female educators from both high schools and colleges, and they represent a variety of geographical regions, racial and ethnic backgrounds, and educational philosophies.

The type of soil strength characteristic (i.e. the variation of soil strength with soil water content) favourable to crop growth depends on both the amount and the distribution of the annual rainfall, and on the nature of the crop. The soil must have sufficient mechanical strength to provide adequate anchorage for the plant throughout its development, and to prevent the collapse of soil water and air pathways by soil overburden pressure and the weight of vehicle and animal traffic. Dense regions of high strength may limit root growth and crop...

In the range of high strain rates, the mechanical behaviour of materials is characterized by an increased strain rate sensitivity, by increasing effects of mass inertia forces and by the adiabatic character of the deformation process. For the relation between stress, strain and strain rate, empirical formulae are now mostly replaced by material laws based on structural mechanical models, whose parameters are to be determined by adequate systematic methods. Also special effects such as the influence of strain rate on...

In Chapter ?? we considered the ways in which one could form new statements from given statements. Now we shall consider an analogous procedure, the formation of new sets from given sets. We shall assume that each of the sets that we use in the combination is a subset of some universal set, and we shall also want the newly formed set to be a subset of the same universal set. As usual, we can specify a newly formed set either by a description or by a listing.

en the space limitations, the added material supplements, expands, and reinforces the ana-lytical methods that were, and continue to be, the main focus of this book. The analytical methods are the foundation of electromagnetics and provide understanding and physical interpretation of electromagnetic phenomena and interactions. Although numerical and computational methods have, especially in the last four decades, played a key role in the solution of complex elec-tromagnetic problems, they are highly dependent on fundamental principles.

Over $4 trillion is currently managed by equity mutual funds in the U.S., with roughly 90 percent invested in actively managed accounts. These mutual funds hold over 25 percent of the outstanding equity value of the average U.S. common stock. This high level of ownership makes it very unlikely that the equity fund industry as a whole is able to outperform the market by a large margin. However, several recent papers show some evidence of manager skills among subgroups of funds (see, for example, Gruber (1996)).

The results of this study suggest that the lowest exposures (concentrations of pollutants) are experienced by train commuters, largely a reflection of the routes being removed from any significant road traffic. Motorcyclists experienced significantly higher average concentrations as a result of high-concentration and very-short-duration peaks not seen in the traces of car and bus commuters travelling on the same road.

The impact of macroeconomics on daily life is less tangible than that of microeconomics. Everyone has to deal with rising supermarket prices, fluctuations in the labor market, and other microeconomic problems. Only a handful of policymakers and government officials really need to worry about fiscal and monetary policy, or about a country’s overall competitiveness.

A NEW CHALLENGE FOR APPLICATION DEVELOPERS Scientific and engineering applications have driven the development of high-performance computing (HPC) for several decades. Many new techniques have been developed over the years to study increasingly complex phenomena using larger and more demanding jobs with greater throughput, fidelity, and sophistication than ever before.
