Energetic state regulates the exploration–exploitation trade-off in honeybees

Energetic trade-off between computing and communication resource in multimedia surveillance sensor network

In recent years, advances in microelectronics have allowed the development of low-power, low-cost, and small devices with sensing, computing, and wireless communication capabilities. An important criterion on the design and operation of these devices is their energy consumptions. Two factors that affect the energy consumption of the sensor network are computation and communication. The simple s...

Uncertainty trade-off and disturbance trade-off for quantum measurements

An important non-classical feature of quantum measurements is the celebrated uncertainty trade-off, namely that the uncertainties in the outcomes of measurements performed on distinct yet identically prepared ensembles of systems cannot all be made arbitrarily small. Recently, we have shown that quantum measurements also exhibit another non-classical feature of disturbance trade-off namely, tha...

The Diversity-Bandwidth Trade-off

The Equity/Efficiency Trade-off in Retrospect

Writing in 1975, Arthur Okun is generally credited with popularizing the idea of a “great tradeoff" between equity and efficiency. Indeed, a generation of economists has been brought up thinking that in the allocation of scarce resources to competing ends, the tradeoff between “equity” and “efficiency” is just another one of the many tough choices that economically rational individuals have to ...

Trade-off between Feedback Load for the Channel State Information and System Performance in MIMO Communications

The performance of multiple-input multiple-output (MIMO) communication systems is greatly increased by having channel state information (CSI) at the transmitter. In systems with no channel reciprocity, a limited feedback link is used to send the CSI from the receiver to the transmitter. However, the resources for the feedback link come at the expense of resources from the communications link. T...
