The combination of Smart Grid and Smart Cities concepts provides municipalities with new capabilities that will lead to better and informed decision making processes. This paper focuses on illustrating key aspects related to a holistic energy efficiency management at a city level, as well as presenting an innovative platform architecture to achieve such objectives. The approach presented focuse...
Interval DEA frontiers are here used in situations where one input or output is subject to uncertainty in its measurement and is presented as an interval data. We built an efficient frontier without any assumption about the probability distribution function of the imprecise variable. We take into account only the minimum and the maximum values of each imprecise variable. Two frontiers are const...

Transactional Memory (TM) intends to simplify the design and implementation of the sharedmemory data structures used in parallel software. Many Software TM systems are based on writerlocks to protect the data being modified. Such implementations can suffer from the “privatization” problem, in which transactional and non-transactional accesses to the same location can lead to inconsistent result...
This paper is devoted to the so-called pessimistic version of bilevel programming programs. Minimization problems of this type are challenging to handle partly because the corresponding value functions are often merely upper (while not lower) semicontinuous. Employing advanced tools of variational analysis and generalized differentiation, we provide rather general frameworks ensuring the Lipsch...
Self-reported measures of life satisfaction may be biased by optimistic or pessimistic dispositions of respondents. In this paper we view life satisfaction as stochastic and estimate a two-tiered quality of life stochastic frontier model to account for upward and downward biases in self-reported quality of life questions. Using the British Household Panel Survey 1995, we interpret the two one-s...
Previous studies have shown that a pessimistic explanatory style is a risk factor for illness, but the factors linking explanatory style and illness are unknown. One's characteristic response to poor health may mediate this relationship. Perhaps pessimistic individuals act helplessly in the face of their symptoms, thereby exacerbating disease. In the present study, we investigated this possibil...
This paper studies abstraction and refinement techniques in the setting of multi-valued model checking for the μ-calculus. Two dimensions of abstractions are identified and studied: Abstraction by joining states of the underlying multi-valued Kripke structure as well as abstraction of truth values, for each following both an optimistic and pessimistic account. It is shown that our notion of abs...
This study examined the relationship between depressive symptoms and bias in the prediction of future life events. Responding to internet announcements, 153 participants varying widely in self-reported depression symptom severity estimated the probability of 40 events occurring over the succeeding 30 days. After the 30-day period, participants reported which events occurred. Optimistic/pessimis...
As there is extensive survey evidence on persistent heterogeneity in unemployment expectations across workers, it a reasonable premise that the expected cost of job loss and resulting provision effort are similarly heterogeneous workers. Based such premise, paper shows significant positive correlation between pessimistic actual which consistently observed with household data can arise novel exp...
