In this article, we investigate the measurement of performance in DMUs in which input and/or output values are given as imprecise data. By imprecise data, we mean that in some cases, we only know that the actual values are inside certain intervals, and in other cases, data are specified only as ordinal preference information. In this article, we present two distinct perspectives for determining...
Abstract Constraints on water resources and increasing the number and variety of water users has led to appeal of the importance of optimal water allocation. The Khanmirza watershed in Chaharmahal Va Bakhtiari Province, has experienced unsustainable development by relying on groundwater resources. As a result of this imbalance, a dramatic drop occurred in the aquifer of the Khanmiza plain. Th...

This paper describes the design and implementation of a distributed file repository that supports data sharing in a variable connected environment. Our design is based on the observation that it is difficult to make a clean cut between the various choices for important issues like consistency and concurrency control when the system is designed. Hence, we make it possible for the user to choose ...
In this paper, we present a new computation scheme for pessimistic bilevel optimization problem, which so far does not have any computational methods generally applicable yet. We first develop a tight relaxation and then design a simple scheme to ensure a feasible and optimal solution. Then, we discuss using this scheme to compute linear pessimistic bilevel problem and several variants. We also...
This research intends to clarify the future prospects of hospital pharmacists and also the factors which influence on their practices of blood drawing or injection by conducting research on their consciousness. We studied it using mail-in survey targeting on randomly selected 476 hospital pharmacists. Study items were the attribution of responders, the prospects of their status in 10 years late...
Temperature change in the future, which is very important in terms of agriculture, development and health, can be one of the consequences of climate change and global warming. Knowing how it can be a significant help to the agricultural sector and development issues and managerschr(chr(chr(chr('39')39chr('39'))39chr(chr('39')39chr('39')))39chr(chr(chr('39')39chr('39'))39chr(chr('39')39chr('39')...
In this paper we present performance measurements in a cluster environment. First, we briefly explain our version of optimistic concurrency control and load balance. Then we compare performance and speed-up of a CORBAand an AspectC++-implementation of a distributed object server for pessimistic and optimistic concurrency control.
Gilbert et al. conclude that evidence from the Open Science Collaboration's Reproducibility Project: Psychology indicates high reproducibility, given the study methodology. Their very optimistic assessment is limited by statistical misconceptions and by causal inferences from selectively interpreted, correlational data. Using the Reproducibility Project: Psychology data, both optimistic and pes...
