Two variants of run-length encoding are the diagram encoding and the pattern substitution algorithms. The diagram encoding is actually a very simple algorithm. Unlike run-length encoding, where the input stream must consists of many repeating elements, “aaaaaaaa” for instance, which are very rare in a natural language, there are many so-called “diagrams” in almost any natural language. In plain English there are some diagrams such as “the”, “and”, “ing” (in the word “waiting” for example), “ a”, “ t”, “ e” and many doubled letters. Actually we can extend those diagrams by adding surrounding spaces. Let’s say we’ve to encode the message “successfully accomplished”, which consists of four doubled letters. // 8 chars replaced by 8 chars!? The problem is that if the input text contains numbers, “2” in particular, we’ve to chose an escape symbol (“@” for example), which we’ll use to mark where the encoded run begins. // the compressed message is longer!!!

10 tools that simplify collaboration
A collaboration tool is something that helps people collaborate. The term is often used to mean collaborative software, but collaboration tools were being used before computers existed. A piece of paper, for example, can be used as collaboration tool. Everything that helps to solve a predefined task together in a group more easily is an effective collaborative tool. Collaboration means, in this context, working together to fulfill a shared, collective, bounded goal. See also Sources Eugene Eric Kim (2005).
Best Online Collaboration Tools - Free and paid tools for online collaboration
Previously, businesses were confined to their offices, where employees dutifully clocked in, worked their eight or nine hour shifts, then clocked out. Now, employees grab their BlackBerrys, laptops or iPads, find wi-fi access, and are good to go at anytime and anywhere ... with the help of online collaboration tools to get the job done. To help businesses make the most of their mobile workforce, many collaboration tools have been created with a variety of features to suit any company, whether large or small. Choosing the right tool will help you not only share documents easily, but also create the right atmosphere for team-building, regardless of where team members are located. 1. Huddle has a highly intuitive easy-to-use interface, so those who have never used an online collaboration tool will be able to quickly figure out how to make the best of all the features provided. 2. The interface is very simple, perhaps too much so, as it is so plain that at times it looks unfinished. 3.

In previous blogs, we focused on web tools to collect and organize content and tools to help students create and present ideas. In this module, we focus on how to use web tools to foster collaboration. Randy Nelson (Pixar University) provides a brilliant definition of collaboration by using two principles of improv. First, accept every offer and second, make your partner look good. Principle 4: Shut up and Listen Good improvisers are not necessarily more clever, or more quick-witted. Principle 5: Action beats inaction Don't talk about doing it, do it. Principle 8: There are no mistakes Earlier I said that we have to be willing to make mistakes. As a quick example, watch this video (caution, one bad word near the end). Imagine what would have happened if the cast would have cut him off. Extending Class and Thinning the Walls A variety of web tools provide opportunities for students to collaborate with each other (in or out of the classroom) or with others outside of the class. Tools

5 Fun and Mathematical Ways to Teach Your Child About Money
This is a guest post by Troy Edwards who writes for the “What is Economics?” blog. For many of today’s students, having to take and master math has as much appeal as a visit to the dentist. For this reason, the savvy parent recognizes that a little “creativity” and fun can go a long way. It can be considered the equivalent of a mother administering a little honey with a spoon of medicine to make it more palatable. photo credit: ~jjjohn~ Since money is a currency of exchange that kids can understand and relate to, there are many ways to work monetary concepts into exercises, real life examples, and games to achieve educational goals. Here are a few things to consider. With this in mind, here are 5 fun and mathematical ways to teach your child about money. 1. photo credit: merfam Allow the little ones to accompany you to the next visit to your local grocers. 2.Play with coins photo credit: midnightglory 3. photo credit: Thomas Hawk 4.Add a language photo credit: bradipo 5.Be the banker
Here are eleven techniques that you can use in your classroom that will help you achieve effective group management and control. They have been adapted from an article called: "A Primer on Classroom Discipline: Principles Old and New" by Thomas R. McDaniel, Phi Delta Kappan, September 1986. 1. Be sure you have the attention of everyone in your classroom before you start your lesson. Inexperienced teachers sometimes think that by beginning their lesson, the class will settle down. The focusing technique means that you will demand their attention before you begin. A soft spoken teacher often has a calmer, quieter classroom than one with a stronger voice. 2. An effective way to marry this technique with the first one is to include time at the end of the period for students to do activities of their choosing. The teacher is more willing to wait for class attention when he knows there is extra time to meet his goals and objectives. 3. 4. 5. 6. 7. 8. 9. 10. 11. Make ample use of praise.
