This paper studies the impact of mortgage curtailment behaviors on the subsequent default and prepayment performance. Although curtailment is not a popular event in the western countries, it is the dominant form of prepayment in Asia and other high saving rate regions. Using a sample of loan-level mortgage performance records from Taiwan, the results of the multinomial logit regressions indicat...

BACKGROUND The Current Opioid Misuse Measure (COMM) is a self-report questionnaire designed to help identify aberrant drug-related behavior in respondents who have been prescribed opioids for chronic pain. The full-length form of the COMM consists of 17 items. Some individuals, especially compromised individuals, may be deterred from taking the full questionnaire due to its length. This study e...

The Center for Epidemiologic Studies–Depression (CES-D) scale is a well-known self-report instrument that is used to measure depressive symptomatology. Respondents who take the fulllength version of the CES-D are administered a total of 20 items. This article investigates the use of curtailment and stochastic curtailment (SC), two sequential analysis methods that have recently been proposed for...

This paper studies the fundamental problem of sizing energy storage given an uncertainty level of variable resources in a microgrid. A queuing theoretical model is introduced, which provides unique insights on the coupling between energy storage size and uncertainty level of the net load. The proposed model lends itself to 3 levels of details: a random walk model with single uncertainty from on...

Growing penetration of wind power challenges to power system security, since the conventional generators may not have sufficient capacity to compensate wind power fluctuation plus the reverse peak regulation. In this paper, the high-capacity pumped-storage and fast-response battery-storage are coordinated to compensate the variation of both wind power and load, aiming at shifting peak load, res...
