In railway applications, performance studies are fundamental to increase the lifetime of railway systems. One of their main goals is verifying whether their working conditions are reliable and safety. This task not only takes into account the analysis of the whole traction chain, but also requires ensuring that the railway infrastructure is properly working. Therefore, several tests for detecting any dysfunctions on their proper operation have been developed.

Abstract: Recent wide-scale deployment of APC connectors in the outside plant for FTTH
initiatives has forced connector manufacturers to consider reliability issues of these
connectors. Angled connectors exhibit two phenomena not found in non-angled
connectors: First, the lower ferrule endface radius of angled connectors makes the
connector more susceptible to permanent fiber withdrawal at elevated temperatures.
Second, any rotation of the ferrule in angled connectors will increase the apex offset of the
There are several key aspects of GUI design that you need to consider when designing and implementing the GUI for your project. At a high level, they can be broken down into two main areas of focus:
1. Designing the GUI to be usable and friendly from the end user’s perspective. 2. Designing and implementing the GUI to be reliable, and maintainable from the programmer’s perspective.
This chapter will focus almost entirely on the first point—ease of use for the end user. We start with a very brief overview of the technical issues you probably want to address in implementing your...
refers to the ability of the event notiﬁcation service to provide a powerful data
model with which to capture information about events, to express ﬁlters and
patterns on notiﬁcations of interest, and to use that data model as the basis
for optimizing notiﬁcation delivery.
Since the advent of the ﬁnancial crisis in the summer of 2007,
each year has brought new challenges to ﬁnancial markets,
the fund industry, and ICI. For us, 2011 will be remembered as
an inﬂection point: a period when the Institute engaged with
more U.S., foreign, and multinational policymakers on more
issues of greater consequence for our members than at any
The accuracy of the cytologic examination from any body site depends greatly on the quality
of collection, preparation, staining and interpretation of the material. Inadequacy in any of
these steps will adversely affect the quality of diagnostic cytology.
Diagnostic accuracy and reliability are major issues in cytology practice.
This is the first of two reports that address the complex issue of incorporating the needs of climate research
into the National Polar-orbiting Operational Environmental Satellite System (NPOESS). NPOESS, which has
been driven by the imperative of reliably providing short-term weather information, is itself a union of heretofore
separate civilian and military programs. It is a marriage of convenience to eliminate needless duplication and
reduce cost, one that appears to be working.
This raises the issue of the measurement of the informal sector, which is known to be substantial in
transition and developing countries. In the former Soviet Union countries it is estimated to contribute
between 20 and 40 per cent of GDP. Even in the European Union (EU) there is considerable informal activity:
in Italy, for example, it has been estimated to contribute between 10 and 20 per cent of GDP. It has been
estimated that the informal sector contributes some nine trillion ‘undetected’ dollars to global GDP.
Traditional software lifecycle development methodologies grew out of a need to control ever-larger development
projects, and the difficulties of estimating and managing these efforts to reliably deliver results. These
methodologies drew heavily on the principles from engineering such as construction management. As a
result, they stressed predictability (one has to plan every last detail of a bridge or building before it is built),
and linear development cycles – requirements led to analysis which led to design which in turn led to
To accomplish this, a reliable transportmechanismis required
in addition to robust modulation and media access, link error
control and fault tolerant routing. The functionalities and design
of a suitable transport solution for WSN are the main issues
addressed in this paper.
The need for a transport layer for data delivery in WSN was
questioned in a recent work  under the premise that data
ﬂows from source to sink are generally loss tolerant.
In this chapter you will: Exploring different communication medium over which we can send data, understanding the issue of encoding bits onto transmission medium so that they can be understood by the receiving end, understanding the issue of encoding bits onto transmission medium so that they can be understood by the receiving end, discussing different technique to detect transmission errors and take the appropriate action.
(BQ) Part 2 book "Computer network - A systems approach" has contents: Simple demultiplexer, remote procedure call, reliable byte stream, performance, issues in resource allocation, queuing disciplines, TCP congestion control, congestion avoidance mechanisms,...and other contents.
We have all heard the saying "It’s what’s inside that counts" at some point in our lives. In the world of
networking Cisco’s Internetwork Operating Systems (IOS) has taken that saying to heart. The very
core of Cisco Systems phenomenal success is the breadth of services provided by the Cisco IOS
No two networks are exactly alike. There are connectivity requirements that differ between healthcare
and manufacturing, entertainment and shipping, finance and telecommunications. Each of which has
different security issues.
Drivers, urban planners and private car park operators have totally different takes on the ”parking” issue. It’s a good thing that Siemens ITS offers proven solutions that open up a new world of parking for everyone. A world where drivers are guided reliably and on the shortest route to the nearest free parking lot by our systems, which thus help substantially reduce traffic in search of a parking space and ensure optimum management of valuable parking space.
This book is intended to provide the reader with a guide to the issues involved with
creating powerful and reliable add-ins for Excel. With years of use, many people build
up the experience and understanding needed to create custom functions for Excel in C
and C++. However, given the very limited books and resources available, this can be a
largely trial-and-error process. The motivation in writing this book is to create something
I wish I had had through the years: a coherent explanation of the relevant technology,
what steps to follow, what pitfalls to avoid, and a good reference guide.
