Social factors in occupational health: a history of hard hats.
Personal protective equipment (PPE) is the least desirable way to ensure workplace safety, and it is difficult to use consistently. Hard hats are different; they have cachet and are often worn even when they are not required. We investigated the history of this personal protective equipment to see if there were any lessons that could be applied to other forms of PPE. We learned that what makes ...
متن کاملHats, auctions and derandomization
We investigate derandomizations of digital good randomized auctions. We propose a general derandomization method which can be used to show that for every random auction there exists a deterministic auction having asymptotically the same revenue. In addition, we construct an explicit optimal deterministic auction for bi-valued auctions.

techniques attempt to differentiate between stego-objects and cover-objects. In recent work we developed an analytic upper bound for the steganographic capacity of LSB based steganographic techniques for a given false of detection. In this paper we look at adaptive steganographic techniques. Adaptive steganographic techniques steps to escape detection. We explore different techniques that can b...
متن کاملOn Hats and other Covers
We study a game puzzle that has enjoyed recent popularity among mathematicians, computer scientist, coding theorists and even the mass press. In the game, n players are fitted with randomly assigned colored hats. Individual players can see their teammates’ hat colors, but not their own. Based on this information, and without any further communication, each player must attempt to guess his hat c...
متن کاملProgram Transformation Using HATS 1.84
This article gives an overview of a transformation system called HATS – a freely available platform independent IDE facilitating experimentation in transformation-oriented software development. Examples are discussed highlighting how the transformational abstractions provided by HATS can be used to solve various problems.
