The present paper deals with the problem of calculating mean delays in polling systems
with either exhaustive or gated service. We develop a mean value analysis (MVA) to
compute these delay figures. The merits of MVA are in its intrinsic simplicity and its
intuitively appealing derivation. As a consequence, MVA may be applied, both in an
exact and approximate manner, to a large variety of models.

This the third edition of the Writing Device Drivers articles. The first article helped to simply get you acquainted with device drivers and a simple framework for developing a device driver for NT. The second tutorial attempted to show to use IOCTLs and display what the memory layout of Windows NT is. In this edition, we will go into the idea of contexts and pools. The driver we write today will also be a little more interesting as it will allow two user mode applications to communicate with each other in a simple manner. We will call this the “poor man’s pipes” implementation.

A web crawler (also known as a web spider or web robot) is a program or automated script
which browses the in a methodical, automated manner. Other less frequently used names for
web crawlers are ants, automatic indexers, bots, and worms (Kobayashi and Takeda, 2000).來(lái)源。

Matlab is an ideal tool for simulating digital communications systems, thanks to
its easy scripting language and excellent data visualization capabilities. One of the
most frequent simulation tasks in the field of digital communications is bit-error-
rate testing of modems. The bit-error-rate performance of a receiver is a figure of
merit that allows different designs to be compared in a fair manner. Performing
bit-error-rate testing withMatlab is very simple, but does require some prerequisite
knowledge

WSNs being energy constrained systems, one major problem is to employ the sensor nodes in such a manner so as to ensure maximum coverage and connectivity with minimal or optimal number of nodes and furthermore elongate network lifetime with maximum energy utilization.
The problem addressed has been tackled for 1-D linear array and further extended to 2-Dimensions as stated in the next slides.

C++ by Dissection presents a thorough introduction to the programming process by
carefully developing working programs to illuminate key features of the C++ programming
language. Program code is explained in an easy-to-follow, careful manner throughout.
The code has been tested on several platforms and is found on the bundled CDrom
accompanying this text. The code in C++ By Dissection can be used with most C++
systems, including those found in operating systems such as MacOS, MS-DOS, OS/2,
UNIX, and Windows.

The book consists of three sections. The first, foundations, provides a tutorial overview of the principles underlying data mining algorithms and their application. The presentation emphasizes intuition rather than rigor. The second section, data mining algorithms, shows how algorithms are constructed to solve specific problems in a principled manner. The algorithms covered include trees and rules for classification and regression, association rules, belief networks, classical statistical models, nonlinear models such as neural networks, and local memory-based models. The third section shows how all of the preceding analysis fits together when applied to real-world data mining problems. Topics include the role of metadata, how to handle missing data, and data preprocessing.

Two scripts are included here.
1. convsys.m - combines the state space representation of two systems connected in series.
[Ao,Bo,Co,Do]=convsys(A1,B1,C1,D1,A2,B2,C2,D2)
This algorithm gives the convolution of two state space representations
| A1 B1 | | A2 B2 |
u ==> | | ==> | | ==> y
| C1 D1 | | C2 D2 |
The algorithm also accepts state space objects as inputs and gives out a state space object as output.
2. sysfeedbk.m
[Ao,Bo,Co,Do]=convsys(A1,B1,C1,D1,A2,B2,C2,D2)
Gives the closed loop state space representation for two systems connected with negative feedback in the following manner.
| A1 B1 |
u ==> | | ==> y
+ o | C1 D1 | |
- | |
| | A2 B2 | |
|= | |= |
| C2 D2 |
The zip file also contains checkcompatibility.m , which checks the compatibility of matrix dimensions in the system and cleanss.m which can be used to clean a state space representation.

Providing QoS while optimizing the LTE network in a cost efficient manner is
very challenging. Thus, radio scheduling is one of the most important functions
in mobile broadband networks. The design of a mobile network radio scheduler
holds several objectives that need to be satisfied, for example: the scheduler needs
to maximize the radio performance by efficiently distributing the limited radio re-
sources, since the operator’s revenue depends on it.
