These routines model tropospheric radiowave propagation over variable terrain and calculates propagation loss vs. height and range. Propagation loss is displayed in dB contours on a height vs. range plot. TPEM is based on the split-step Fourier PE method and was originally developed from an early PE model called PEPC, written by Fred Tappert. Propagation loss over variable terrain is modeled by shifting the field an appropriate number of bin widths correspondc ing to the height of the ground. The field is determined using the smooth earth PE method.
It has been suggested1 that an appropriate figure of merit for a low probability of intercept and
detection (LPI/D) waveform is the quantity “Range x Bandwidth / Joule”. That is, the further the
range, the wider the bandwidth and the less amount of energy used to achieve these values, the
more covert is the resultant communications system.
OReilly.Java.Rmithis book provides strategies for working with serialization,
threading, the RMI registry, sockets and socket factories, activation,
dynamic class downloading, HTTP tunneling, distributed garbage
collection, JNDI, and CORBA. In short, a treasure trove of valuable
RMI knowledge packed into one book.
This book uses the Python language to teach pro
-
gramming concepts and problem
-solving skills, without assuming any previous program- ming experience. With easy-to-understand examples, pseudocode, flowcharts, and other
tools, the student learns how to design the logic of programs and then implement those
programs using Python. This book is ideal for an introductory programming course or a
programming logic and design course using Python as the language.
As with all the boolts in the
Starting Out With
series, the hallmark of this text is its clear,
friendly, and easy
-to-understand writing. In addition, it is rich in example programs that
are concise and practical. The programs in this book include short examples that highlight
specific programming topics, as well as more involved examples that focus on problem
solving. Each chapter provides one or more case studies that provide step
-by-step analysis
of a specific problem and shows the student how to solve it.
Huffman codes
In telecommunication, how do we represent a
set of messages, each with an access
frequency, by a sequence of 0’s and 1’s?
To minimize the transmission and decoding
costs, we may use short strings to represent
more frequently used messages.
This problem can by solved by using an
extended binary tree which is used in the 2-
way merging problem.
The SP486 and SP487 are low–power quad differential line drivers meeting RS-485 and RS-422
standards. The SP486 features a common driver enable control the SP487 provides independent
driver enable controls for each pair of drivers. Both feature tri–state outputs and wide
common–mode input range. Both are available in 16–pin plastic DIP and SOIC packages.
The CSS Cookbook cuts straight through the theory to provide hundreds of useful examples and CSS code recipes you can use immediately to format your web pages. Reflecting CSS2 and including topics that range from basic web typography and page layout to techniques for formatting lists, forms, and tables, the CSS Cookbook is a must-have resource for any web author who has even considered using CSS.
