A cognitive approach to opposites:
In the present paper, opposites are examined and discussed, and a way of describing them from a cognitive perspective is suggested. Related research disagrees upon whether opposites are symmetrical, and whether concepts should be integrated in the relation of opposites. The Swedish opposites levande 'alive' and död 'dead' have been studied thoroughly in order to provide empirical data. Argument...
متن کاملIntensity statistics of Friedel opposites.
A previous analysis of the average intensity and mean-square intensity difference of Friedel opposites, confined to the space group P1 [Flack & Shmueli (2007). Acta Cryst. A63, 257-265], is here extended to all the non-centrosymmetric space groups. The present analysis presumes purely non-centrosymmetric content of the unit cell. An important result of this study is that the average intensity a...
متن کاملPaired Structures and other opposites-based models
In this paper we present a new class of fuzzy sets, paired fuzzy sets, that tries to overcome any conflict between families of fuzzy sets that share a main characteristic: that they are generated from two basic opposite fuzzy sets. Hence, the first issue is to formalize the notion of opposition, that we will assume dependent on a specific negation, previously determined. In this way we can defi...
متن کاملPooling in Manufacturing : Do Opposites Attract ?
In a stochastic environment pooling naturally leads to economies of scale, but heterogeneity can also create variability. In this article, we investigate this trade-off in the case of a manufacturing environment. Pooling for queueing systems has been widely investigated while much less attention has been given to manufacturing systems where jobs are given a due date upon arrival. In such system...

Much of the research on an Internet of Things assumes that users will be able to connect devices without consent by or interference from their service providers. However, in cable and satellite television networks, cellular networks, and some broadband Internet networks, the service provider often only allows use of set-top boxes, smart phones, and residential gateways obtained directly from th...
