Exponential Diversity Achieving Spatio-Temporal Power Allocation Scheme for Fading Channels
In this paper, we analyze optimal (in space and time) adaptive power transmission policies for fading channels when the channel-state information (CSI) at the transmitter (CSIT) an...

Discrete Power Control: Cooperative and Non-Cooperative Optimization
— We consider an uplink power control problem where each mobile wishes to maximize its throughput (which depends on the transmission powers of all mobiles) but has a constraint o...

Combined QoS scheduling and call admission control algorithm in cellular networks
— In this paper, a scheduling problem in wireless networks is considered when there simultaneously exist CBR (constant bit rate) users requiring exact minimum average throughput ...

Playing games with approximation algorithms
In an online linear optimization problem, on each period t, an online algorithm chooses st S from a fixed (possibly infinite) set S of feasible decisions. Nature (who may be adve...

On Coherent Rotation Angles for As-Rigid-As-Possible Shape Interpolation
Morphing algorithms aim to construct visually pleasing interpolations (morphs) between 2D or 3D shapes. One of the desirable properties of a morph is avoiding selfintersections of...
