Research Article A MIMO-OFDM Testbed, Channel Measurements, and System Considerations for Outdoor-Indoor WiMAX
To understand an entity’s internal control, the auditor will evaluate the design and implementation of a control.
The auditor's primary consideration is whether, and how, a specific control prevents, or detects and corrects, material misstatements in classes of transactions, account balances or disclosures.
The heaviest emphasis by auditors is on controls over classes of transactions rather than account balances or disclosures
System Architecture III Distributed Objects presents of real time - software considerations; buffering example cd controller; continuous operation; example - routers and other network computing; example - transaction monitor; software reuse - application packages; reuse - objects basic definitions; objects distributed objects; object request broker (orb); interface definition language; distributed objects and the system life cycle
In writing this book the author has been primarily concerned with the presentation
of the basic essentials of power-system operation and analysis to students in the
final year of first degree courses at universities and colleges of technology. The
emphasis is on the consideration of the system as a whole rather than on the engineering
details of its constituents, and the treatment presented is aimed at practical
conditions and situations rather than theoretical nicety.
The HVAC designer cannot neglect consideration of the sound and
vibration generated by HVAC equipment. This chapter briefly discusses
the fundamentals of sound and vibration control. References
for further study are cited at the end of the chapter.
The objectives of the project were to review developments in embedded system design and future trends, and to explore board-level rapid prototyping using FPGAs. The embedded process design flow consists of many important steps that make it essential to achieve a functioning final product within the allocated design time. In order to make appropriate decisions, embedded systems hardware and software knowledge is an important requirement. The embedded hardware decisions are analyzed in terms of processor, memory, and peripheral requirements and limitations.
In keeping with the objectives of the previous editions, the third edition
is intended to provide broad coverage of satellite communications
systems, while maintaining sufficient depth to lay the foundations for
more advanced studies. Mathematics is used as a tool to illustrate
physical situations and obtain quantitative results, but lengthy mathematical
derivations are avoided. Numerical problems and examples
can be worked out using a good calculator or any of the excellent mathematical
computer packages readily available.
Flight controls have advanced considerably throughout the years. In the earliest
biplanes flown by the pioneers flight control was achieved by warping wings
and control surfaces by means of wires attached to the flying controls in
the cockpit. Figure 1.1 clearly shows the multiplicity of rigging and control
wires on an early monoplane. Such a means of exercising control was clearly
rudimentary and usually barely adequate for the task in hand.
- Packaging is the science, art, and technology of enclosing or protecting products for distribution, storage, sale, and use.
Packaging can be described as a coordinated system
Many companies conduct extensive research on color schemes, designs and types of product packaging that is the most appealing to its intended consumers.
At $13 billion and roughly five percent of the total semiconductor market (2004
data) the power semiconductor market is big and growing fast, typically outgrowing
the rest of the semiconductor market.
Modern electronic appliances, while exhibiting increasing functionality, are
also expected to consume little power, for reasons of portability, thermal performance,
and environmental considerations.
In recent years, all western industrialized countries, and to a growing extent
even many developed and developing Asian nations, have witnessed a remarkable
growth in numbers of older people . Future projections anticipate continued
increases, particularly in numbers of individuals who are 85 years and older .
Although US statistics have indicated recent declines in disability trends , overall
numbers of older individuals living with disability and functional dependence
are likely to increase given projected increases in life expectancy .
Because of the fast-evolving nature of technology and the issues and opportunities faced
by public-sector managers as they wrestle with the information age, it is perhaps not
surprising that this second edition of the Handbook of Public Information Systems
contains approximately two thirds new material, including a whole new section on
e-government. I wish to thank all those in government service, schools of public administration,
and elsewhere who contributed to this volume, either directly or as reviewers.
In this paper we propose a methodology for investigating the relationship between architectures of natural language generation (NLG) systems and stylistic properties of texts. Biber's (1988) methodology is used to obtain both the characterisation of style of our corpus and the division of the corpus into sets of linguistically similar texts. These sets will be used for studying the architectural aspects.
In the belief that the establishment of a first-class Terminal Market system, worthy of twentieth century requirements, is a matter of vital importance to every family in New York, I have spent considerable time during the past few months investigating markets on both sides of the Atlantic.
As a result I am more than ever conscious of the need for an enlightened public opinion to support the efforts of the Terminal Market Commission to secure this benefit for our community.
To give appropriate translation equivalents for target words is one of the most fundamental problems in machine translation systrms. Especially, when the MT systems handle languages that have completely different structures like Japanese and European languages as source and target languages. In this report, we discuss about the data strucutre that enables appropriate selections of translation equivalents for verbs in the target language. This structure is based on the concepts strucutre with associated information relating source and target languages.
This chapter describes the functions and operations of intrusion detection systems (IDS) and intrusion prevention systems (IPS). It explains the underlying IDS and IPS technology embedded in the Cisco IOS IPS solutions. It describe the use of signatures, the need for IPS alarm monitoring, and the design considerations in deploying IPS.
Chapter 14 - Enterprise system risks and controls. A consideration of utmost importance for enterprise system designers, managers, and auditors is the consideration of risk and control. The objective of this chapter is to introduce some types of risk that occur in enterprises and discuss how these risks may be lessened by controls designed into enterprise information systems. This chapter uses the REA pattern as a framework for identifying types of risks and controls to mitigate those risks.
Chapter 7 - Infrastructure, cloud computing, metrics, and business continuity planning: building and sustaining the dynamic enterprise. In this chapter, students will be able to: Describe how a service-oriented architecture can be used as a philosophical approach to help the organization of the future meet all its IT-related needs, define and describe the various hardware and software infrastructure considerations in an organization.
Zn the past decade, a number of natural language database access systems have been constructed (e.g. Hendrix 1976; Waltz et e l . 1976; Sacerdoti 1978; Harris 1979; Lehner~ and Shwartz 1982; Shvartz 1982). The level of performance achieved by natural language database access systems varies considerably, with the sore robust systems o p e r a t i n g v i t h t n a narrow domain ( i . e . , content area) and r e l y i n g heavily on domain-specif i c knowledge to guide the language understanding process.
