Systems Analysis and Design: Chapter 15 - Designing Accurate Data Entry Procedure's Objectives is Understand the uses of effective coding to support users in accomplishing their tasks; Design effective and efficient data capture approaches for people and systems.
Data communications and networking are changing the way we do business and the way
we live. Business decisions have to be made ever more quickly, and the decision makers
require immediate access to accurate information. Why wait a week for that report
from Germany to arrive by mail when it could appear almost instantaneously through
computer networks? Businesses today rely on computer networks and internetworks.
(USGS) is to assess the quantity and quality of the
natural resources of the Nation and to provide
information that will assist resource managers and
policymakers at Federal, State, and local levels in
making sound decisions. Assessment of water-quality
conditions and trends is an important part of this
One of the greatest challenges faced by waterresources
scientists is acquiring reliable information
that will guide the use and protection of the Nation’s
Given a collection of records (training set )
Each record contains a set of attributes, one of the attributes is the class.
Find a model for class attribute as a function of the values of other attributes.
Goal: previously unseen records should be assigned a class as accurately as possible.
A test set is used to determine the accuracy of the model. Usually, the given data set is divided into training and test sets, with training set used to build the model and test set used to validate it.
Fully updated for Xcode 4.2, Pro Core Data for iOS explains how to use the Core Data framework for iOS SDK 5 using Xcode 4.2. The book explains both how and why to use Core Data, from simple to advanced techniques. Covering common and advanced persistence patterns, this book prepares any iOS developer to store and retrieve data accurately and efficiently.
Effective data presentation is an essential skill for anybody wishing to display or publish research results, but when done badly, it can convey a misleading or confusing message. This new addition to the popular “How to” series explains how to present data in journal articles, grant applications or research presentations clearly, accurately and logically, increasing the chances of successful publication.
Building an accurate Named Entity Recognition (NER) system for languages with complex morphology is a challenging task. In this paper, we present research that explores the feature space using both gold and bootstrapped noisy features to build an improved highly accurate Arabic NER system.
We present a simple but accurate parser which exploits both large tree fragments and symbol reﬁnement. We parse with all fragments of the training set, in contrast to much recent work on tree selection in data-oriented parsing and treesubstitution grammar learning. We require only simple, deterministic grammar symbol reﬁnement, in contrast to recent work on latent symbol reﬁnement.
Data-driven function tag assignment has been studied for English using Penn Treebank data. In this paper, we address the question of whether such method can be applied to other languages and Treebank resources. In addition to simply extend previous method from English to Chinese, we also proposed an effective way to recognize function tags directly from lexical information, which is easily scalable for languages that lack sufﬁcient parsing resources or have inherent linguistic challenges for parsing. ...
A wide range of supervised learning algorithms has been applied to Text Categorization. However, the supervised learning approaches have some problems. One of them is that they require a large, often prohibitive, number of labeled training documents for accurate learning. Generally, acquiring class labels for training data is costly, while gathering a large quantity of unlabeled data is cheap. We here propose a new automatic text categorization method for learning from only unlabeled data using a bootstrapping framework and a feature projection technique.

The Illustrated Dictionary of Electronics—8th Edition has been revised, clarified, and updated, reflecting technological advances of recent years. New definitions have been added in the fields of wireless technology, robotics, and artificial intelligence. Every effort has been made to be concise and accurate, without “talking down” to the reader.
Risk assessment of chemical substances is an ever-developing discipline. Transparent and accurate
risk assessments are necessary for decision-makers to make wise risk management decisions. The
outcome of risk assessments may have enormous economical consequences, in addition to the
consequences for human health and the environment. Globalization is a fact, with huge possibilities
for economic and social prosperity. Food and consumer products are produced in one part of the
world and put on the market in another....
Nowadays we assist to the increasing of devices and equipments connected to power systems (non-linear loads, industrial rectifiers and inverters, solid-state switching devices, computers, peripheral devices etc). Hence, the parameters of the power supply should be accurately estimated and monitorized. For this purpose have been proposed power quality monitoring systems that are abble to automatically detect and classify disturbances.
The questionnaire (survey) is a useful tool for Tyne and Wear University (TWU) to access and justify the success of the safety bus. In order to collect the greatest number of respondents with accurate response, the university need to design and distribute the effective questionnaire.
The reason for choosing the questionnaire is caused by several advantages it brings to the business. According to Robson, Pemberton and McGrane (2011), the questionnaire seems to cover a numerous people, so, it increases the sample size....
The logical data design is the middle stage of the natural progression from
conceptual design to physical design. The process of deriving a logical data
design from the conceptual data design accomplishes the following:
Translates conceptual data needs into real data requirements.
You must turn the conceptual data needs identified during conceptual design
into actual entities and relationships that will define how the data interacts.
Helps organize your thinking about the data.
A data model is an integrated collection of concepts for
describing and manipulating data, relationships between
data, and constraints on the data in an organization.
• A model is a representation of “real world” objects and
events, and their associations. It is an abstraction that
concentrates on the essential, inherent aspects of an
organization and ignores accidental properties.
• A data model must provide the basic concepts and notations
that will allow database designers and end-users
unambiguously and accurately to communicate their
understanding of the organizational data....
One redundant characteristic of dismantling operations of nuclear facilities is the lack of
exhaustive and accurate data relating to the actual state of the facilities. Most of the time the
harsh working conditions (heat, dust, radiological contamination...) are rated far too severe
for human workers to carry out the work. As a consequence robots are set to take over from
human staff. It is necessary to use flexible, powerful and remotely-operated manipulator
arms that are fitted with specially-designed processes and tools for cutting, handling and
It would be possible to create a score for each respondent from the factor analysis, and this approach
is widely considered to be good practice when scoring complex data
. However, there is also a strong
argument for giving each component of financial knowledge equal weighting, as each has benefits for
individuals, and each has been identified as important by international experts.
Presentations play an important role in both your education and career at all levels. Presentations include the integration of all skills -- reading, writing, listening, speaking, and research -- to make oral and visual communication serve an aim. In education, the aim can be to give new or cumulative information, and in the business world, to introduce new products or services and/ or revamp existing ones.
