The aim of this paper is to find normative foundations of Approval Voting.In order to show that Approval Voting is the only social choice functionthat satisfies anonymity, neutrality, strategy-proofness and strict mono-tonicity we rely on an intermediate result which relates strategy-proofnessof a social choice function to the properties of Independence of IrrelevantAlte...

Agents partition deterministic outcomes into good or bad. A direct revelation mechanism selects a lottery over outcomes — also interpreted as time-shares. Under such dichotomous preferences, the probability that the lottery outcome be a good one is a canonical utility representation. The utilitarian mechanism averages over all deterministic outcomes “approved” by the largest number of agents. I...

We consider the problem of allocating a set on indivisible items to players with private preferences in an efficient and fair way. focus valuations that have dichotomous marginals, which added value any item is either 0 or 1, aim design truthful allocation mechanisms (without money) maximize welfare are fair. For case submodular we such deterministic mechanism. The output by our mechanism Loren...

Signals with direct spread spectrum are widespread in modern communication and navigation systems. Often for channels which such signals used, significant changes the carrier frequency relation to information speeds of received characteristic. In particular, Doppler shift. Therefore, estimation plays a key role solving problem initial synchronization demodulators spectral broadening. first part...
