How to be sarcastic: The echoic reminder theory of verbal irony.

Abstract: Les conditions dans lesquelles un enonce est reconnu comme sarcastique varient selon que l'enonce est positif ou negatif. Il est rendu compte de cette asymetrie a l'aide de la theorie «du rappel en echo» (un sarcasme fait alusion a une situation antecedente) dans un cas et aux normes et attentes sociales dans l'autre cas (enonce positif) ― 3 experiences avec des scenaris contenant ou non des «victimes» testent cette hypothese

Algorithms for facility location problems with outliers

Abstract: Facility location problems are traditionally investigated with the assumption that all the clients are to be provided service. A significant shortcoming of this formulation is that a few very distant clients, called outliers, can exert a disproportionately strong influence over the final solution. In this paper we explore a generalization of various facility location problems (K-center, K-median, uncapacitated facility location etc) to the case when only a specified fraction of the customers are to be served. What makes the problems harder is that we have to also select the subset that should get service. We provide generalizations of various approximation algorithms to deal with this added constraint.

Performance analysis of priority schemes for IEEE 802.11 and IEEE 802.11e wireless LANs

Abstract: The IEEE 802.11 distributed coordination function (DCF) enables fast installation with minimal management and maintenance costs, and is a very robust protocol for the best effort service in wireless medium. However, the current DCF is unsuitable for real-time applications. This paper studies backoff-based priority schemes for IEEE 802.11 and the emerging IEEE 802.11e standard by differentiating the minimum backoff window size, the backoff window-increasing factor, and the retransmission limit. An analytical model is proposed to derive saturation throughputs, saturation delays, and frame-dropping probabilities of different priority classes for all proposed priority schemes. Simulations are conducted to validate analytical results. The proposed priority schemes can be easily implemented, and the results from this paper are beneficial in designing good priority parameters.
