A vast literature focuses on the predictability of U.S. and international stock returns using macroe-
conomic variables, such as the short government interest rate or the yield spread between defaultable
and government bonds. For instance, Ferson and Harvey (1993) nd that returns on international
stock indexes are predictable using macroeconomic indicators as conditioning variables. More
strikingly, Ferson and Harvey (1999) nd that broad economic variables explain the cross-sectional
variation in U.S. individual stock returns better than the Fama and French (1993) empirical factors.
In this paper, we address the problem of reducing the unpredictability of userinitiated dialogue contributions in humancomputer interaction without explicitly restricting the user’s interactive possibilities. We demonstrate that it is possible to identify conditions under which particular classes of user-initiated contributions will occur and discuss consequences for dialogue system design.
Models for Dynamic Systems. Since their introduction by Isaac Newton in the seventeenth century, differential equations have provided concise mathematical models for many dynamic systems of importance to humans. By this device, Newton was able to model the motions of the planets in our solar system with a small number of variables and parameters. Given a ®nite number of initial conditions (the initial positions and velocities of the sun and planets will do) and these equations, one can uniquely determine the positions and velocities of the planets for all time....

ME-430 INTRODUCTION TO COMPUTER AIDED DESIGN
A steady state thermal analysis calculates effects of constant thermal loads on a model and is used to determine temperatures, heat flow rates, and the heat fluxes in a part. A steady state analysis is commonly used as a precursor to a transient thermal analysis to determine the initial conditions.

The high-pressure cylinder of a turbogenerator unit receives 1,000,000 lb per h (454,000 kg / h) of steam at initial conditions of 1800 psia (12,402 kPa) and 1050 F (565.6 C).
In 1991, David Gale and Raphael Robinson, building on explorations carried out by Michael Somos in the 1980s, introduced a three-parameter family of rational recurrence relations, each of which (with suitable initial conditions) appeared to give rise to a sequence of integers, even though a priori the recurrence might produce non-integral rational numbers. Throughout the '90s, proofs of integrality were known only for individual special cases. In the early '00s, Sergey Fomin and Andrei Zelevinsky proved Gale and Robinson's integrality conjecture.

4.1 INTRODUCTION In this chapter, we consider another application of the extended Kalman ﬁlter recurrent multilayer perceptron (EKF-RMLP) scheme: the modeling of a chaotic time series or one that could be potentially chaotic. The generation of a chaotic process is governed by a coupled set of nonlinear differential or difference equations.
4 Do Initial Conditions Persist between Firms? An Analysis of Firm-Entry Cohort Eﬀects and Job Losers Using Matched Employer-Employee Data. 4.1 Introduction Economists have long been interested in how persistent the eﬀects of short-term unexpected shocks in the labor market are on workers’ careers (e.g., Okun 1973)
In this research, the growth and metabolic activities of Saccharomyces cerevisiae immobilized in alginate gel during alcoholic fermentation with different initial glucose concentration were studied. Starting from initial glucose concentration at 140 g/L, we observed that increasing this concentration to 220 g/L had little effect on the growth of immobilized yeast. Under the same conditions, the maximum biomass, glucose uptake rate, and final ethanol concentration obtained in the immobilized yeast cultures were always higher than those in the free yeast cultures....
Each Federal Reserve Bank gathers anecdotal information on current economic conditions in its District through reports from Bank and Branch directors and interviews with key businessmen, economists, market experts, and other sources. The Beige Book summarizes this information by District and sector.
It may have already occurred to you that this "toughest job you'll ever love seems almost
impossible. Look at some of the obstacles you may be facing. Your students are numerous;
many may be older than you. Textbooks are scarce, and again, many may be older than you.
The physical conditions are austere, with a tin roof that creaks as the temperature rises and
obliterates all other sound when the rains come. Pictures and posters disappear from the
classroom walls. Desks are too few. The blackboard has been worn to a light grey and chalk
This book proposes a framework for a national-scale program to monitor changes
in mercury concentrations in the environment following the reduction of atmospheric
mercury emissions. The book is the product of efforts initiated at a workshop held
in Pensacola, Florida, in September 2003, involving more than 30 experts in the
fields of atmospheric mercury transport and deposition, mercury cycling in terrestrial
and aquatic ecosystems, and mercury bioaccumulation in aquatic food webs and
Then the system is switched into automatic mode. Digital computers are often used to replace the manual adjustment process because they can be readily coded to produce complicated functions for the start-up signals. Care must also be taken when switching from manual to automatic. For example, the integrators in electronic controllers must be provided with the proper initial conditions. 2 . . Reset Windup 875 In practice, all actuators and final control elements have a limited operating range.
FUZZY MODELING AND CONTROL OF CHAOTIC SYSTEMS
Chaotic behavior is a seemingly random behavior of a deterministic system that is characterized by sensitive dependence on initial conditions. Chaotic behavior of a physical system can either be desirable or undesirable, depending on the application. It can be beneficial in many circumstances, such as enhanced mixing of chemical reactants. Chaos can, on the other hand, entail large-amplitude motions and oscillations that might lead to system failure....
There are many factors accounting for losses after rice harvest and occurs as
as early as pre-harvest period and the next stage from harvesting to storage. the
the appearance of cracks in the rice-harvest period reduces the yield.
Grain can be damaged or lost quantity and quality due to inappropriate
practice in the sun time, harvest, harvest, dam / mechanical drying, loading / unloading,
transport, milling and processing storage conditions.
Milling process is an important stage because it produces the final product (white rice).
