C is the number of correctly recognized words, I is the number of incorrect recognitions and N is the number of total words. A simulation of 200 runs is performed. To this end, a two small but well-known databases are used. The simulations are performed in two phases: the training phase and the testing phase. During the training phase, different words are estimated by GMM models and stored in the codebook to be used later during the testing phase. During the testing phase, unknown words are presented

One the day we were presented with the New Destinations project, the Looney Tunes group quickly jumped the gun on the topic of promotional items. Immediately we started to brainstorm which items would be the best; we came up with carpenter pencils, tape measures, magnets, and drink cozies. Once we narrowed down our choice of promotional items, with the help of Cheri, we sided with magnets and measuring tapes. Quickly, we began to search on the Internet for websites that would give us the best deal

Introduction: There are many ways of developing software but of the most popular one that is being followed by a lot of companies is called waterfall model. This method is easy to flow and no matter how big the project is it can be useful. Most of the software developers use this method by capturing the requirements from the client, once the complete of set requirements are captured, the developer move on to design phase where the set of requirements have been completely designed. After designing

Problem: A number N is called “nice” if a square can be dissected into N non-overlapping squares. What numbers are “nice”? Why? Problem Solving Process: During the entry phase I wrote down the number n is called nice and n can be cut up into nonoverlapping squares. For the want to know section, I wrote which squares are nice? Since I missed the first day of working on this problem, my group understood that only perfect squares were nice and we went right into the attack phase. For example, a 2

Unit 1 Research Assignment 1: Exploring Programming Language Structured Query Language (SQL) is a specialized language for updating, deleting, and requesting information from databases. SQL is an ANSI and ISO standard, and is the de facto database query language. A variety of established database products support SQL, including products from Oracle and Microsoft SQL Server. It is widely used in both industry and academia, often for enormous, complex datbases. (Base, 2013). SQL was developed in
