The state of the art of the machine industry has experienced a rapidly accelerating evolution since the outset of the ﬁrst industrial revolution. Modern machines are required to perform to varying requirements of accuracy, productivity, and surface ﬁnish requirements. It is the purpose of this discussion to establish some guidelines of machine system design to attain the desired performance requirements of accuracy, surface ﬁnish, etc. Modern industrial machines are considered as a total system comprised of the control, drive, and machine....

A project of this magnitude and scope is never the work of only one person. It
requires the support of many individuals. Such is the case here, and I mention some
of those individuals below. I am indebted to them and many others for sharing their
knowledge and giving me opportunities over the years to gain valuable experience
and achieve intellectual growth.
I’m deeply indebted to Marc Holzer, of Rutgers University-Newark, for the
inspiration to promote government performance and the countless learning and
growth opportunities he has provided me....
We believe that .NET developers cannot achieve systematically high-performance software solutions without
thoroughly understanding all three areas. For example, .NET memory management (facilitated by the CLR
garbage collector) is an extremely complex field and the cause of significant performance problems, including
memory leaks and long GC pause times. Without understanding how the CLR garbage collector operates,
high-performance memory management in .NET is left to nothing but chance. Similarly, choosing the proper
collection class from what the .
Zheng (1999) further develops the analyses of Gruber (1996), expanding the
data set to cover the universe of all equity funds between 1970 and 1993. She
finds that funds that enjoy positive net f lows subsequently perform better on
a risk-adjusted basis than funds that experience negative net f lows. She also
examines whether a trading strategy could be devised based on the predictive
ability of net f lows and finds evidence that information on net f lows into smal
funds could be used to make risk-adjusted profits....
In this activity, you will reorganize your candidate components to take int
account additional constraints or requirements. Microsoft Official Curriculum (MOC), available to IT Academies at a discounted price, is professional courseware intended for IT professionals and developers who build, support, and implement solutions by using Microsoft products and technologies. MOC is designed to cover the topics that employers know are mission-critical in the real world.
Engineered barriers to isolate potentially harmful waste
from humans and ecosystems have been used for over 35
years, and much has been written about them and their constituent
components. However, few reports have provided an
overall assessment of the performance of engineered barrier
systems. The last broad assessment was conducted in 1995
(Rumer and Mitchell, 1995). Since that time, new materials
and sensor technologies have been introduced and models to
predict contaminant transport have improved.
In finance and healthcare, event processing systems handle
sensitive data on behalf of many clients. Guaranteeing
information security in such systems is challenging
because of their strict performance requirements in terms
of high event throughput and low processing latency.
We describe DEFCON, an event processing system
that enforces constraints on event flows between event
processing units. DEFCON uses a combination of static
and runtime techniques for achieving light-weight isolation
of event flows, while supporting efficient sharing of
In this paper we investigate how much data is required to train an algorithm for attribute selection, a subtask of Referring Expressions Generation (REG). To enable comparison between different-sized training sets, a systematic training method was developed. The results show that depending on the complexity of the domain, training on 10 to 20 items may already lead to a good performance.
We consider the problem of answering complex questions that require inferencing and synthesizing information from multiple documents and can be seen as a kind of topicoriented, informative multi-document summarization. The stochastic, graph-based method for computing the relative importance of textual units (i.e. sentences) is very successful in generic summarization.
The Littoral Combat Ship (LCS) is a relatively small surface combatant vessel intended to perform littoral or coastal missions where highspeed maneuverability, agility, and sprint speed are required. In early 2005, the U.S. Navy commissioned the RAND Corporation to evaluate the operational, logistical, and cost implications of modules being developed and put into service aboard the LCS, a new platform that, through modular design, can be rapidly reconﬁgured to suit changing tactical situations. The ships will com...
In the manufacturing industry, however, the word robot means a
reprogrammable stationary manipulator with few, if any sensors, com-
monly found in large industrial manufacturing plants. The third common
meaning of robot is a teleoperated vehicle similar to but more sophisti-
cated than a radio controlled toy car or truck. This form of robot usually
has a microprocessor on it to aid in controlling the vehicle itself, perform
some autonomous or automatic tasks, and aid in controlling the manipu-
lator if one is onboard....
Crane testing requirements for performance tests includes both operational performance testing and load performance testing. the following tables and their associated guidelines are of a general nature.
A Anybody can call themselves an accountant,
but a recognised qualification
generally guarantees proper training,
experience and professional standards.
5 Most accountants work in-house for
companies or organisations in the
private, public or voluntary sectors.
Those employed by accountancy firms,
on the other hand, usually specialise in
\0 very specific areas, such as auditing,
taxation, insolvency or forensic accounting.
Naturally, each specialism has
different training requirements.
Welcome to CST MICROWAVE STUDIO®, the powerful and easy to use
electromagnetic field simulation software. This program combines both a user friendly
interface and simulation performance in an unsurpassed manner.
With its native Windows based user interface you will feel familiar with the simulation
environment straight away. This means that you can immediately start caring about your
actual electromagnetic problem rather than dealing with a cryptic proprietary user
interface. Excellent visual feedback at all...
As stated in Chapter 1, Section 1.2, requirements for International Mobile Telecommunications-2000 (IMT-2000) include system ﬂexibility, economy and conditions on data transmission speed deﬁned in numerical terms. The minimum performance requirement in terms of transmission speed is 2 Mbit/s in an indoor environment, 384 kbit/s in a pedestrian mode and 144 kbit/s in a vehicle mode.
East and Southern Europe), India, parts of South America, Southwest U.S./northern Mexico and
Australia. The operating characteristics of STPPs are relatively well matched with the
intermediate and peak electricity load requirements in these regions.
Two types of collectors have been used in STPPs: parabolic trough and central receiver.
Electricity is generated by incorporating the solar collectors with a Rankine cycle power plant or
as an add-on to a natural gas combined cycle (referred to as an ISCCS).
