A roofing shingle for enhanced wind/rain durability embodies two transverse lines of adhesion. A first discontinuous line of adhesive joins the butt edge of an overlying shingle to the underlying shingle. Secondly, a band of sealant adjacent the top edge of an underlying shingle seals against an overlying shingle to prevent penetration by wind driven rain to the roof deck. A reduced headlap is thereby permitted, thereby either reducing shingle size or extending shingle coverage. Exposed portions of the sealant band improve the erosion resistance of underlying shingles.

Embodiments are described herein to provide an efficient, adaptive and distributed approach to wireless resource allocation that seeks to maximize system capacity and/or coverage on the reverse link. The general approach is for each cell (sector) base station to allocate (102) its mobile units to frequency subbands based on a local optimization objective. This objective takes into account the performance “costs” to the neighboring cells/sectors of transmissions by different mobile units in different subbands. An example of such an optimization objective can be the maximization of the “utility” of user transmission rates within the sector minus the cost of the transmissions to neighboring cells/sectors.
