Poorly performing enterprise applications are the weakest links in a corporation's management chain, causing delays and disruptions of critical business functions. This groundbreaking book frames enterprise application performance engineering not as an art but as applied science built on model-based methodological foundation. The book introduces queuing models of enterprise application that visualize, demystify, explain, and solve system performance issues.
Written by a team of expert SQL users, this comprehensive resource approaches performance tuning from a new perspective by showing you a methodical scientific approach to diagnose performance problems. The book first walks you through how to discover bottlenecks when something is wrong and you’ll then learn how to identify and remove the problems that are causing poor performance. You’ll discover preventive measures you can take to try to avoid a performance problem entirely and you’ll learn how to achieve better performance....
Performance Appraisals. Two words that can make the hair stand on end for both employees
Poorly done, performance appraisals can leave you with underperformers who lack the direc-
tion to change their behavior, good performers who feel unrecognized for their work, and,
worse yet, problem employees who should be dismissed, but a lack of appropriate documenta-
tion prevents this.
The dialogue strategies used by a spoken dialogue system strongly influence performance and user satisfaction. An ideal system would not use a single fixed strategy, but would adapt to the circumstances at hand. To do so, a system must be able to identify dialogue properties that suggest adaptation. This paper focuses on identifying situations where the speech recognizer is performing poorly. We adopt a machine learning approach to learn rules from a dialogue corpus for identifying these situations. ...
Essential oils (also called volatile oils) generally extracted by
distillation from plants are hydrophobic liquids containing
volatile aromatic compounds. The essential oils are widely
used in perfumes, cosmetics as well as in food and drink as
flavor additives. Some essential oils show multiple pharmacological
activities and have been considered as the major active
fractions of herbal medicines [1–3].
This paper describes our work on building Part-of-Speech (POS) tagger for Bengali. We have use Hidden Markov Model (HMM) and Maximum Entropy (ME) based stochastic taggers. Bengali is a morphologically rich language and our taggers make use of morphological and contextual information of the words. Since only a small labeled training set is available (45,000 words), simple stochastic approach does not yield very good results. In this work, we have studied the effect of using a morphological analyzer to improve the performance of the tagger. ...
The record, however, shows that in many, if not most, developing coun-
tries, the poor have by and large not benefited from government pro-
grams and projects in these areas. The reason, of course, has been the
weak capacity of government. States with weak institutions have to find
other ways to deliver basic social services and economic infrastructure
to their poor citizens. One of these ways is to work in partnership with
private sector and community organizations, sometimes called civil so-
We address the problem of translating from morphologically poor to morphologically rich languages by adding per-word linguistic information to the source language. We use the syntax of the source sentence to extract information for noun cases and verb persons and annotate the corresponding words accordingly. In experiments, we show improved performance for translating from English into Greek and Czech. For English–Greek, we reduce the error on the verb conjugation from 19% to 5.4% and noun case agreement from 9% to 6%. ...
Part II of this book focuses on financial markets, markets in which funds are trans-
ferred from people who have an excess of available funds to people who have a short-
age. Financial markets such as bond and stock markets are crucial to promoting
greater economic efficiency by channeling funds from people who do not have a pro-
ductive use for them to those who do. Indeed, well-functioning financial markets are
a key factor in producing high economic growth, and poorly performing financial
markets are one reason that many countries in the world remain desperately poor.
I knew I had to look for new ways to guide my children's education.
As a mother as well as an accountant, I have been concerned by the lack of financial education our
children receive in school. Many of today's youth have credit cards before they leave high school, yet
they have never had a course in money or how to invest it, let alone understand how compound
interest works on credit cards. Simply put, without financial literacy and the knowledge of how
money works, they are not prepared to face the world that awaits them, a world in which spending is
emphasized over savings....
Methods of collecting job analysis information
1. Direct observation Direct Observation is a method of job analysis to observe and record behavior / events / activities / tasks / duties while something is happening.
2. Work methods analysis Work methods analysis is used to describe manual and repetitive production jobs, such as factory or assembly-line jobs. Work methods analysis includes time and motion study and micro-motion analysis.
3. Critical incident technique (CIT model).
Report on the Millennium Development Goals (MDGs) in
Zimbabwe pointed out that notwithstanding the poor performance of the economy,
Zimbabwe has made relative progress in a number of key areas such as universal
primary education. Enrolment in primary schools has consistently been relatively high (with
a net enrollment ratio of 91% in 2009 down from 98.5% in 2002). The rate of HIV infection
has also seen an improvement with a decline from 16.1 percent in 2007 to 13.7 percent by
2009 partly on account of public awareness programs and education.
Conflict is a part of life that many of us tend to avoid and fear.
Traditional schooling gives us little training to handle conflict,
and most of us have poor role models from which to learn.
Despite the lack of attention we give it, conflict has the power to
destroy self-esteem, relationships, and even corporations.
Conversely, it also has the power to generate creativity, better
solutions, next-level thinking, and passionate results. Conflict
when handled poorly is incredibly destructive. Conflict when
handled well turns mediocre businesses into stellar corporations...
Pig production is an expert of farmers in Thua Thien Hue and Quang Nam, more than 80% of sows, are kept in small farm holdings. To meet increasing demand for pig husbandry systems for pigs, smaller owners have enhanced breeding and feeding systems, while others tried to continue to produce larger pigs poorly designed facilities.
Customers expect manufacturers to provide excellent quality, reliable delivery
and competitive pricing. This demands that the manufacturer’s machines
and processes are highly reliable. But what does the term ’highly reliable’
Certainly, with manufacturing, process and service industries becoming
progressively dependent on the reliability of fewer but more sophisticated
machines and processes, it means that poor equipment operating performance
is no longer affordable or acceptable.
There is also a good dataset for open-end real estate funds. Over the last 10
years, investors in this asset class have been able to achieve a higher average
annual return than on investments in equity funds (see Fig. 16). However,
compared with most bond funds, open-end real estate funds come off worse.
This relationship has also generally been maintained over longer periods of up
to 20 years: however it is probably also be affected by the poor performance of
the stock market in the last few years. On a 30-year average, equity funds with
an investment focus in Germany...
This book is a quick-reference guide for tuning Oracle SQL. This is not a comprehensive Oracle tuning book. The purpose of this book is to give you some light reading material on my "real world" tuning experiences and those of my company, Mark Gurry & Associates. We tune many large Oracle sites. Many of those sites, such as banks, large financial institutions, stock exchanges, and electricity markets, are incredibly sensitive to poor performance. With more and more emphasis being placed on 24/7 operation, the pressure to make SQL perform in production becomes even more critical.
Milk from the udder of a healthy cow contains very few bacteria.
Poor hygiene introduces additional bacteria that make the milk
spoil quickly. To ensure that the milk remains fresh for a longer
time it is necessary to practice good hygiene. Good hygiene needs
to be observed at all stages of milk production, handling and
marketing. Therefore you need to advise the farmer on hygienic
milk production and handling after milking.
ADC’s HDSL2/4 line cards provide visibility of faulty or missing remote chassis frame ground
connections on a real-time basis. A remote unit not connected to frame ground is susceptible to
poor performance and possible damage to HDSL and other transmission equipment. This has
become an increasingly critical factor in the delivery of T1 service to cell sites. Cell sites are
particularly vulnerable to power surges, induction and changes in ground potential caused by RF
transmission equipment and lightning strikes.
