6. Sabermetric Thinking

Slice ePub May 27, 2014

I think that this chapter contains the most fun set of hacks in the book. I like scoring games, searching for data, and compiling databases. But the reason for doing all of these things is to learn more about baseball, which is what this chapter is all about.

The term sabermetrics comes from SABR, the Society for American Baseball Research (see http://www.sabr.org for more information). In 1974, Bill James, Pete Palmer, and Dick Cramer started a statistics committee to encourage the exchange of ideas on baseball. These three pioneers, and many other committee members, popularized thinking about baseball statistics and strategy. As described in Chapter 5, they developed some of the most famous formulas in baseball. Over time, this type of numbers-based thinking has come to be known as sabermetrics.

In this chapter, I examine some classic questions about baseball and some questions of my own. Some fellow baseball fans have contributed to this chapter, and I hope you enjoy reading their hacks as much as I did. These hacks arent designed just to answer questions about baseball, but to teach you how to answer questions about baseball.

Abstract- With the rapid increase in low-cost and sophisticated digital technology the need for techniques to authenticate digital material will become more urgent. Inspired by the image forgery detection, we develop a method to detect the forgery in VoIP audio streams by checking the offset differential features with learning machine. Our experimental results on Speex VoIP streams show that our approach is promising to expose the forgery manipulation in VoIP audio streams.

Keywords- Multimedia forensics, forgery detection, SVM classifier, speex, VoIP

Introduction

Recently, there has been a tremendous increase in the use of

VoIP applications. In some cases, they may be submitted as digital evidence. If these files are being submitted as digital evidence, then there is a need to authenticate such material. In order to authenticate such material, there is an urgent need to develop authentication methods for VoIP files. Digital watermarking and signature are the two typical technologies for digital multimedia authentication. These two techniques need some side information such a signature or digital watermark at the time of detection. Since, it is impossible to retrieve any available side information from the questionable data; these methods are useless in many real applications.

144. Varicose Veins

Slice ePub January 13, 2014

Varicose veins, which usually occur in the legs, are bluish, swollen, stretched veins that can often be seen bulging through the skin. This condition sometimes causes discomfort and aching in the legs, especially when it is first beginning to develop. Thought to be due in part to heredity, varicose veins cannot be reversed. Surgery to remove as many of the veins as possible is sometimes undertaken. However, natural steps can be taken to improve the appearance of the veins, reduce the associated discomfort, and possibly reduce the chances of more developing.

VIII Our Lost Paradise

Slice ePub October 05, 2013

I RETURNED from Evans to Denver feeling more strongly than ever the attraction of the cattle business in this glorious country of unlimited free range, but I had not quite made up my mind as yet to go in for it. Also, before deciding, there was still one place I particularly wanted to see, the Wet Mountain Valley, of which I had heard men speak very highly. I was told that the whole floor of the valley was open grazing land like the Plains, but it was shut in by pine-clad mountains, which provided splendid natural shelter for stock. So I struck out for Cañon City on Methusalem, knowing that from there some sort of road or trail into the Valley could be found. Stopping overnight at a ranch on Fountain Creek on my road, a man told me that, if I cared to ride off my route for a mile or so up the cañon where the creek came out of the mountains, I should there behold the sight of my life.

“That’s a real big spring of pure soda-water,” he explained, “bubbling up into a great basin out of the solid rock, and from thar’ it runs over and tumbles into the Fountain Creek; you never saw the like of it in all your born days.”
