In decision making problems, there may be the cases where the decision makers express their judgements by using preference relations with incomplete information. Then one of the key issues is how to estimate the missing preference values. In this paper, we introduce an incomplete interval...

In this paper, an output-feedback-type wide area damping control (WADC) strategy is presented as a supplementary control of high-voltage direct current (HVDC) transmission to enhance thestability of large-scale interconnected power systems. This strategy can effectively suppress the...

We explore the relationship between some correlations and complete power in intersection-union tests. We invalidate the approach of using the product of individual powers from testing each individual hypothesis as a lower bound estimate of the complete power, assuming nonnegative correlations.

In order to simulate the uncertainty associated with impression or vagueness, a decision maker may give her/his judgments by means of triangular fuzzy reciprocal preference relations in the process of decision making. The study of their consistency becomes a very important aspect to avoid a...

This paper presents a comprehensive study on a controllable two-phase flow ejector component efficiencies and ejector performances in transcritical CO2 refrigeration cycles. A two-phase flow ejector expansion model was developed and experimentally validated. A method of determining the...

Traditional performance evaluation measures do not account for tail events and rare disasters. To address this issue, we reinterpret the riskiness measures of Aumann and Serrano (2008) and Foster and Hart (2009) as performance indices. We derive the moment properties of these indices and their...

Kunming City is accelerating the process of agricultural modernization, industrialization, informationization and ecological development. In this process, it needs speeding up building new high level and advanced rural practical skilled personnel team suitable for development demand. By...

Motivated by social and biological interactions, a novel type of phase transition model is provided in order to investigate the emergence of the clustering phenomenon in networks. The model has two types of interactions: one is attractive and the other is repulsive. In each iteration, the phase...

Regressions often use pre-orthogonalized regressors: prior to the main regression, an independent variable xi is regressed upon the other regressor(s), and its residuals are used in the right-hand side of the main regression instead of the raw variable itself. For example, the exposure of a...
