Tunneling 100 ft below a busy city with varying substructure is a delicate job, especially when the work comes .....A.... 8 ft of existing tunnels. Such is the case on San Francisco's new $1.5-billion Central Subway Project, which began major subterranean excavation last month.
"The tunnels pass through both soft ground and Franciscan formation, which is heterogeneous rock that is not predictable except in its unpredictability," says Sarah Wilson, a San Francisco Municipal Transportation Agency (SFMTA) resident engineer.
While underground conditions will be tricky, the project's twin earth-pressure-balance tunnel-boring machines will be able to adjust their blades and cut through any sand, dirt or rock, says Wilson. The TBMs, dubbed Mom Chung and Big Alma, are each 350 ft long and weigh 750 tons.
Mom Chung was first out of the 450-ft-long launch box. Over the next 10 months, she will travel north, creating a 1.7-mile-long tunnel. Big Alma will begin digging a southbound parallel tunnel later this month.
The tunnels are the main component of the Central Subway Project, which is extending the Muni Metro T Third Line through one of the most densely populated neighborhoods in the U.S. with three new underground stations and one at street level. Work on the line is scheduled to wrap up in 2019.
To prevent and control ground and adjacent structure settlement, the team will use compensation grouting, in which a horizontal array of grout pipes is installed into a shaft drilled down next to the tunnel alignment. "We are basically preconditioning the ground and making it homogeneous so that there are no surprises for the crossing," says John Funghi, SFMTA program director.

Application and multi-server management provides the DBA with the tools necessary to gain centralized insights into instance and database application utilization as well as a better way to develop, deploy, and manage data-tier applications.

For mobile computers and telephones, cellular radio is the up-and-coming technology. GSM, CDPD, and CDMA are widely used.
The IEEE 802 LANs are: CSMA/CD, token bus, and token ring. Each of these has its own unique advantages and disadvantages, and each has found its own user community and will probably continue to serve that community for years to come. Convergence to a single LAN standard is an unlikely event. A new addition to this family is DQDB, being sold as a MAN in many cities.
An organization with multiple LANs often connects them with bridges. When a bridge connects two or more different kinds of LANs, new problems arise, some of them insoluble.

Testing, examination and interviewing are methods which can result in effective assessments of people.
Procedural programming has been around since the inception of computers and programming. Object-oriented paradigms arrived a little later - in the late 1950s to early 1960s - which means over 50 years of object-oriented problem solving. Still, many developers lack a full understanding of the thought process in developing object-oriented software and therefore can’t take advantage of its concepts. I’m happy to see that this book, The Object-Oriented Thought Process, has taken this fairly old perspective and given it full attention and renewed interest.
Not having read the previous editions, I’m not familiar with the changes represented in this fourth edition. Author Matt Weisfeld is a professor who understands these important concepts and the level of knowledge and process required for readers and students to grasp what they need to know. The examples in the book are concise, clear, and easy to follow. Additionally, the book makes good use of white space, lists, pictures, and diagrams to make the content easier to follow and scan quickly.
Weisfeld has organized the concepts to build on each other, ensuring that students understand one concept well before moving to the next. On the other hand, readers who already understand the fundamentals can go directly to object-oriented thought processes for particular programming paradigms, such as Web services or client-server applications.
The book is language-neutral. Its examples are in C#, but a supplementary website offers example code in other languages. If your language isn’t fairly represented, don’t be deterred from acquiring this book because object-oriented concepts and semantics are mostly universal - just the particular implementation might vary due to the language.
Each chapter contains UML and example code to better understand the concepts and see how they’re implemented. The last chapter introduces design patterns but without going into great detail about how to use them. This lets the inexperienced reader know that design patterns would be the next step in the path to developing good code.
Overall, I can recommend this book to code developers, designers, and testers - to anyone with an interest in proper software development semantics. It's available in a digital format that serves as a useful ready reference.

The author of the review states that he is unware of how the current edition differs from the others.
“Algorithms may require several different types of operations to be performed on sets. For example, many algorithms need only the ability to insert elements into, delete elements from, and test membership in a set. We call a dynamic set that supports these operations a dictionary. Other algorithms require more complicated operations.”
Segundo o texto,
“In 1968, Knuth published the first of three volumes with the general title The Art of Computer Programming. The first volume ushered in the modern study of computer algorithms with a focus on the analysis of running time, and the full series remains an engaging and worthwhile reference for many of the topics presented here.”
De acordo com o texto, o primeiro volume da série de livros publicada por Knuth
“Analyzing an algorithm has come to mean predicting the resources that the algorithm requires. Occasionally, resources such as memory, communication bandwidth, or computer hardware are of primary concern, but most often it is computational time that we want to measure.”
Sobre o texto, é correto afirmar que
“If computers were infinitely fast, any correct method for solving a problem would do.”
A ideia que ela transmite é de que
In the text, the verb form “retrieve” (l.8) is synonymous with apply.
