Indicators for Social and Economic Coping Capacity - Moving Toward a Working Definition of Adaptive Capacity”, Wesleyan-CMU Working Paper.

by Gary Yohe , Richard S J Tol , Gary Yohe , 2001
"... Abstract This paper offers a practically motivated method for evaluating systems' abilities to handle external stress. The method is designed to assess the potential contributions of various adaptation options to improving systems' coping capacities by focusing attention directly on the u ..."

Section 2 uses a more formal representation of vulnerability to show how overall coping capacity might be judged

Abstract—A Gaussian interference channel (IC) with a relay is considered. The relay is assumed to operate over an orthogonal band with respect to the underlying IC, and the overall system is referred to as IC with an out-of-band relay (IC-OBR). The system can be seen as operating over two parallel interferencelimited channels: The first is a standard Gaussian IC and the second is a Gaussian relay channel characterized by two sources and destinations communicating through the relay without direct links. We refer to the second parallel channel as OBR Channel (OBRC). The main aim of this work is to identify conditions under which optimal operation, in terms of the capacity region of the IC-OBR, entails either signal relaying and/or interference forwarding by the relay, with either a separable or non-separable use of the two parallel channels, IC and OBRC. Here “separable ” refers to transmission of independent information over the two constituent channels. For a basic model in which the OBRC consists of four orthogonal channels from sources to relay and from relay to destinations (IC-OBR Type-I), a condition is identified under which signal relaying and separable operation is optimal. This condition entails the presence of a relay-to-destinations capacity bottleneck on the OBRC and holds irrespective of the IC. When this condition is not satisfied, various scenarios, which depend on the IC channel gains, are identified in which interference forwarding and non-separable operation are necessary to achieve optimal performance. In these scenarios, the system exploits the “excess capacity ” on the OBRC via interference forwarding to drive the IC-OBR system in specific interference regimes (strong or mixed). The analysis is then turned to a more complex IC-OBR, in which the OBRC consists of only two orthogonal channels, one from sources to relay and one from relay to destinations (IC-OBR Type-II). For this channel, some capacity resuls are derived that parallel the conclusions for IC-OBR Type-I and point to the additional analytical challenges. I.

Peak Power and Interference Outage Probability Constrained Optimal Transmission Policy for Underlay Cognitive Radios

by Salil Kashyap, Student Member, Neelesh B. Mehta, Senior Member
"... Abstract—In an underlay cognitive radio (CR) system, a secondary user (SU) can transmit even when the primary is on but under stringent constraints on the interference that it causes at the primary receiver (PRx). The interference constraint fundamentally influences and changes how the SU transmits. ..."

. We develop a novel and optimal transmit power policy for an SU that minimizes its symbol error probability (SEP) when it is subject to two practically motivated constraints, namely, a peak transmit power constraint and an interference outage probability constraint. We derive new expressions
