Evaluation of Intelligent Intrusion Detection Models
This paper discusses an evaluation methodology that can be used to assess the performance of intelligent techniques at detecting, as well as predicting, unauthorised activities in networks. The effectiveness and the performance of any developed intrusion detection model will be determined by means of evaluation and validation. The evaluation and the learning prediction performance for this task will be discussed, together with a description of validation procedures. The performance of developed detection models that incorporate intelligent elements can be evaluated using well known standard methods, such as matrix confusion, ROC curves and Lift charts. In this paper these methods, as well as other useful evaluation approaches, are discussed.Peer reviewe
RAROC Based Capital Budgeting and Performance Evaluation: A Case Study of Bank Capital Allocation
This paper describes the RAROC system developed at Bank of America (B of A) in order to examine how risk-based capital allocation models work. I begin by discussing the economic rational for allocating capital in a diversified organization like the B of A. Drawing on recent work by Froot and Stein (1995) and Stein (1996), I argue that the capital budgeting process used by the B of A resembles the operation of an internal capital market in which businesses are allocated capital with the objective of mitigating the costs of external financing. Viewing the capital budgeting process in this way is useful because it suggests that a businesses contribution to the overall variability of the cash flows of the bank will be an important factor in evaluating the risk of (and the capital allocated to) a specific business unit. In addition, since RAROC systems are used both for capital budgeting and management compensation, the measures of risk are designed to limit rent seeking and influence activities by division managers, Next, given the theoretical background, I provide a detailed look at how the RAROC capital allocation and performance evaluation system works at B of A. The primary objective of B of A's system is to assign equity capital to business units (and ultimately to individual credits) so each business unit has the same cost of equity capital. This process implies that investments in riskier projects or business units (measured by the projects contribution to the overall volatility of the market value of the bank) will be required to use less leverage than investments in less risky business units.

An Assessment of PIER Electric Grid Research 2003-2014 White Paper
This white paper describes the circumstances in California around the turn of the 21st century that led the California Energy Commission (CEC) to direct additional Public Interest Energy Research funds to address critical electric grid issues, especially those arising from integrating high penetrations of variable renewable generation with the electric grid. It contains an assessment of the beneficial science and technology advances of the resultant portfolio of electric grid research projects administered under the direction of the CEC by a competitively selected contractor, the University of California’s California Institute for Energy and the Environment, from 2003-2014
Measurement techniques and instruments suitable for life-prediction testing of photovoltaic arrays
Array failure modes, relevant materials property changes, and primary degradation mechanisms are discussed as a prerequisite to identifying suitable measurement techniques and instruments. Candidate techniques and instruments are identified on the basis of extensive reviews of published and unpublished information. These methods are organized in six measurement categories - chemical, electrical, optical, thermal, mechanical, and other physicals. Using specified evaluation criteria, the most promising techniques and instruments for use in life prediction tests of arrays were selected

Distribution System Voltage Management and Optimization for Integration of Renewables and Electric Vehicles: Research Gap Analysis
California is striving to achieve 33% renewable penetration by 2020 in accordance with the state’s Renewable Portfolio Standard (RPS). The behavior of renewable resources and electric vehicles in distribution systems is creating constraints on the penetration of these resources into the distribution system. One such constraint is the ability of present-‐‑day voltage management methodologies to maintain proper distribution system voltage profiles in the face of higher penetrations of PV and electric vehicle technologies. This white paper describes the research gaps that have been identified in current Volt/VAR Optimization and Control (VVOC) technologies, the emerging technologies which are becoming available for use in VVOC, and the research gaps which exist and must be overcome in order to realize the full promise of these emerging technologies
