The book is intended to provide an introduction to the effects of nonlinear elements in feedback control systems. A central topic is the use of the Describing Function (DF) method since in combination with simulation it provides an excellent approach for the practicing engineer and follows on logically from a first course in classical control, such as the companion volume in this series. Some of the basic material on the topic can be found in my earlier book which is frequently referenced throughout the text....
NONOSCILLATORY HALF-LINEAR DIFFERENCE EQUATIONS AND RECESSIVE SOLUTIONS
ˇ ´ MARIELLA CECCHI, ZUZANA DOSLA, AND MAURO MARINI Received 30 January 2004 and in revised form 26 May 2004
Recessive and dominant solutions for the nonoscillatory half-linear diﬀerence equation are investigated. By using a uniqueness result for the zero-convergent solutions satisfying a suitable ﬁnal condition, we prove that recessive solutions are the “smallest solutions in a neighborhood of inﬁnity,” like in the linear case.
We present a novel transition system for dependency parsing, which constructs arcs only between adjacent words but can parse arbitrary non-projective trees by swapping the order of words in the input. Adding the swapping operation changes the time complexity for deterministic parsing from linear to quadratic in the worst case, but empirical estimates based on treebank data show that the expected running time is in fact linear for the range of data attested in the corpora.
.\lodern linguistic theory attributes surface complexity to interacting snbsystems of constraints. ["or instance, the I D LP gr,'unmar formalism separates constraints on immediate dominance from those on linear order. 5hieber's (t983) I D / I . P parsing algorithm shows how to use ID and LP constraints directly in language processing, without expandiqg them into an intcrmrdiate "object g a m m a r . " However, Shieber's purported O(:,Gi 2 .n ~) runtime bound underestimates the tlillicnlty of I D / L P parsing. I D / L P parsing is actually NP-complete, anti the worst-case runtime of...
The Affordable Care Act, landmark health legislation passed
in 2010, created the National Prevention Council and called
for the development of the National Prevention Strategy to
realize the benefits of prevention for all Americans’ health. The
National Prevention Strategy is critical to the prevention focus
of the Affordable Care Act and builds on the law’s efforts to
lower health care costs, improve the quality of care, and provide
coverage options for the uninsured.
Preventing disease and injuries is key to improving America’s
MTMF combines the best parts of the Linear Spectral Mixing model and the statistical
Matched Filter model while avoiding the drawbacks of each parent method (Boardman,
1998). It is a useful Matched Filter method without knowing all the possible endmembers in
a landscape especially in case of subtle, sub-pixel occurrences. Firstly, pixel spectra and
endmember spectra require a minimum noise fraction (MNF) (Green et al., 1988, Boardman,
1993) transformation. MNF reduces and separates an image into its most dimensional and
This chapter deals with independent component analysis (ICA) for nonlinear mixing models. A fundamental difﬁculty in the nonlinear ICA problem is that it is highly nonunique without some extra constraints, which are often realized by using a suitable regularization. We also address the nonlinear blind source separation (BSS) problem. Contrary to the linear case, we consider it different from the respective nonlinear ICA problem.
Notice the essential difference between equation (2.1.8) and equation (2.1.6). In the latter case, the C’s must be applied to b in the reverse order from that in which they become known. That is, they must all be stored along the way.
This chapter deals with independent component analysis (ICA) for nonlinear mixing models. A fundamental difﬁculty in the nonlinear ICA problem is that it is highly nonunique without some extra constraints, which are often realized by using a suitable regularization. We also address the nonlinear blind source separation (BSS) problem. Contrary to the linear case, we consider it different from the respective nonlinear ICA problem. After considering these matters, some methods introduced for solving the nonlinear ICA or BSS problems are discussed in more detail.
In Memory of Dick and Brian Abstract A group is locally ﬁnite if every ﬁnite subset generates a ﬁnite subgroup. A group of linear transformations is ﬁnitary if each element minus the identity is an endomorphism of ﬁnite rank. The classiﬁcation and structure theory for locally ﬁnite simple groups splits naturally into two cases—those groups that can be faithfully represented as groups of ﬁnitary linear transformations and those groups that are not ﬁnitary linear. This paper completes the ﬁnitary case.
The resulting view, that financial markets can be subject to inherent instability,
induces governments to intervene to provide depositor protection in some form or
other. Explicit deposit insurance is one approach, while an explicit or implicit deposit
guarantee is another. In either case, general prudential supervision also occurs to limit
the risk incurred by insurers or guarantors. To control the incentives of bank owners
who rely too heavily on government funded deposit insurance, governments typically
enforce some control over bank owners.
Another case in example is Ferrari, which has a programme called ‘One–to–One’, where
with the help of a Ferrari advisor, a customer can modify virtually every part of the car,
which does no affect reliability.
To bring the story a little closer to home, Viren Bhagat, a jeweller from Mumbai, who
specializes in bespoke pieces, believes in the take–it–or–leave–it attitude. He believes
that allowing a customer to make changes to the design destroys the uniqueness of the
price. He also insists that a customer visit his office to buy the price. ...
Certain works like agriculture or pests killing represent the biggest risks of acute
intoxication, while there is a latent danger for the population at large in their food chain
(Ospina et al, 2009) (Thundiyil et al, 2008).
The agricultural development model in Colombia is mainly based upon the use of agro
chemicals and according data reported by the Public Health Surveillance System of
Colombia (SIVIGILA), there were in 2008 6.650 intoxication cases for the use of pesticides
followed by 7.405 cases in 2009 and 8.
It is estimated that NRs. 0.5 billion per year in tourism revenue is lost due to air
pollution in Kathmandu valley (World Bank, 1997). Findings of a survey conducted
among 1,702 tourists between May and June 2001 by MARG Nepal indicate that
the quality of air is the number one area where tourists feel improvement is needed.
This shows that Kathmandu’s poor transportation system and pollution is not only
affecting human health and environmental quality, but also the tourism industry
(Business Age, 2001).
In most cases the resources (financial, human, and others) required for addressing all
identified water quality problems significantly exceed the resources allocated to the
water pollution control sector. Priorities, therefore, need to be assigned to all problems in
order to concentrate the available resources on solving the most urgent and important
problems. If this is not done the effect may be an uncoordinated and scattered
management effort, resulting in a waste of scarce resources on less important problems.

In bringing together the results of the presentations highlighted
in this paper, it becomes clear that aesthetic and artistic activities
typically involve a network of brain regions distributed over both
hemispheres, rather than a specialized area.
