IEEE SIGNAL PROCESSING LETTERS‚ VOL. 21‚ NO. 7‚ JULY 2014 829 Discrete Anamorphic Transform for Image Compression Mohammad H. Asghari‚ Member‚ IEEE‚ and Bahram Jalali‚ Fellow‚ IEEE Abstract—To deal with the exponential increase of digital data‚ new compression technologies are needed for more efficient representation of information. We introduce a physics-based transform that enables image compression by increasing the spatial coherency. We also present the Stretched Modulation Distribution‚ a

Dictogloss represents a major shift from traditional dictation. When implemented conscientiously‚ dictogloss embodies sound principles of language teaching which include: learner autonomy‚ cooperation among learners‚ curricular integration‚ focus on meaning‚ diversity‚ thinking skills‚ alternative assessment‚ and teachers as colearners. These principles flow from an overall paradigm shift that has occurred in second language education (Jacobs & Farrell‚ 2001). While there are many variations on

Access log sampler Step-by-step This is a short tutorial on Jmeter’s access log sampler. The purpose of the access log sampler is to provide an easy way to simulate production traffic. There are several benefits to using access logs. 1. rather than guess what users are doing‚ the test plan is using real traffic data 2. as the traffic pattern changes‚ the access log provides a record of individual changes and general shifts in usage 3. access logs contain a lot of useful data‚ which may provide

Any research done without documenting the study so that others can review the process and results is not an investigation using the scientific research process. The scientific research process is a multiple-step process where the steps are interlinked with the other steps in the process. If changes are made in one step of the process‚ the researcher must review all the other steps to ensure that the changes are reflected throughout the process. Parks and recreation professionals are often involved in

1. Books are concentrated sources of wisdom. The more books you read‚ the more wisdom you expose yourself to. What are some books you can start reading to enrich yourself? Some books I’ve read and found useful are Think and Grow Rich‚ Who Moved My Cheese‚ 7 Habits‚ The Science of Getting Rich and Living the 80/20 Way. I’ve heard positive reviews for The Tipping Point‚ Outliers and The Difference Maker‚ so I’ll be checking them out soon. 2. Learn a new language. As a Singaporean Chinese‚ my

Step 1: Go online‚ head to the library or search an academic database. Don’t hesitate to ask a reference librarian to help you. That’s why they’re there. •Know which sources are acceptable to your teacher. •Does your teacher want a certain number of primary sources and secondary sources? •Can you use Wikipedia? Wikipedia is often a good starting point for learning about a topic‚ but many teachers won’t let you cite it because they want you to find more authoritative sources. •Take detailed
