We show how stability as a solution concept in matching often comes at the cost of extreme forms on inequality. Restricting our attention to aligned preferences, we that stable results from lexicographic welfare maximization pairs’ welfare, starting with best-off. compare this an alternative allocation, although unstable, maximizes lexicographically worst-off pairs.

Abstract This article will consider the ways states have exercised imperialism over Antarctica, focusing on two methods: use of administrative acts and control scientific research resources. The then compare Outer Space Treaty Antarctic System around these methods, as well military capabilities an important aspect imperial control, to question whether space law prohibits imperialism. seeks prev...

In the previous chapter it became evident that the Zimbabwean space economy is very unequal in terms of socio-economic development and that there are several development problems. Over the years the Zimbabwean government, like other governments in countries with severe spatial inequalities in development, has adopted various policies and strategies to obtain a more equal spatial distribution of...

This study examines the robust facility layout problem (RFLP) while taking into account unpredictable health and environmental safety standards. problem's major goal is to arrange departments in various of a hall, allot each department appropriate amount space, identify kind amenities equipment needed for chosen sector. To accomplish aforementioned objective, five criteria were taken account: t...

A space-time coded orthogonal frequency-division multiplexed (STC-OFDM) system is proposed to transmit layered video signals over wireless channels. The space-time coding can provide a diversity gain for the multiple-antenna system while OFDM can alleviate the frequency-selective fading effect. An input video sequence is compressed and partitioned into layers with different priorities. Then, an...
