The safety of workers in the construction industry is a big concern because of the high number of fatalities and injuries that occur in the industry. Selecting contractors based on safety performance can improve safety and reduce the risks of injuries. However, owners commonly choose contractors based on competitive bidding...
The objective of this investigation is the development
of improved techniques for the estimation of robustness for
dynamic systems with structured uncertainties, a problem
which was approached by application of the Lyapunov direct
method. This thesis considers the sign properties of the
Lyapunov function derivative integrated along finite intervals
of...
The development of modern industries calls for the
robotic manipulators with high speed and accurate tracking
performance. Many authors have paid attention to robust
control of robotic manipulators; however, only few authors
have also considered the control problem of manipulators
with power limitation.
In this dissertation, the robotic manipulator is...
An investigation focusing on methods of estimation
of robustness of nominally linear dynamic systems with
unstructured uncertainties was performed.
The algorithm proposed involves the consideration
of an associated system, selection, and subsequent
development, of Liapunov function candidate and integration
of their derivatives along the solution trajectory.
A nominally linear multi-dimensional...
The Lyapunov direct method is utilized to determine the
robustness bounds for nonlinear, time-variant uncertainies
p[subscript i]. Determination of the robustness bounds consists of two
principal steps: (i) generation of a Lyapunov function and
(ii) determination of the bounds based on the generated
Lyapunov function. Presently in robustness investigations,
a...
This thesis presents a method for determining the
kinematic geometry of arthropod legs. A kinematic
description makes possible the analysis of arthropod leg
motion, as a prelude to investigating how various arthropod
species are able to negotiate diverse terrains. Such
knowledge will aid in design of legged vehicles.
The focus...
In the problem of testing the median using a random sample from a
certain distribution, and if no other parametric family is suggested,
the t-test is known to be the optimal procedure when this distribution
is normal. If the sample appears to be non-normal, one has the choice
either to...
IIFET 2008 Vietnam keynote presentation. Power Point presentation by Professor Ola Flaaten from The Norwegian College of Fishery Science, University of Tromso.
T cells are one of the key cells in the immune system. Although they are not the first line of defense against a pathogen, their functions can greatly enhance the phagocytosis and destruction of pathogens as well as the development of antibody responses. Furthermore, even when responding T cells have...
Government financial transfers (GFTs) to the marine capture fishery sectors in OECD Member countries represent a significant policy intervention. These transfers have a variety of objectives and governments employ a number of means to implement them. This paper reviews an OECD study and discusses the findings in the context of...
