introduction:expensive chemical tests are usuallyapplied to control the efficiency of wastewater treatment plants. however, the cost of measuring these parameters is one of the challenges of the wastewater treatment plants. using statistical methods has been evaluated for possibility of calculating expensive parameters by measuring the inexpensive parameters in this study. methods:initial sampl...

this paper examines the effects of corporate governance (board structure and ownership structure) and some financial variables on financial statement restatements. for this purpose, citing firms have been divided into two groups: a group comprising firms (48 firms) that have maximum amount of the annual adjustment (more than 5% of ebit) and a group (control group; 46 firms) comprising firms tha...

philosophy of mathematics suited well the ‘‘general emphasisin later nineteenth-century mathematics on revisiting foundationalquestions’’ (p. 61). Pure geometry as it emerged from Frege, Paschand Hilbert, provided a diagram-free, purely sentential notion ofproof, which has lasted unto our own day.In the second, and greater, part of the book, Greaves traces outthe interre...

The status of the search for pentaquark baryon states is reviewed in light of new results from the first two dedicated experiments from CLAS at Jefferson Lab and of new analyses from several labs on the Θ + (1540). Evidence for and against the heavier pentaquark states, the Ξ(1862) and the Θ 0 c (3100) observed at CERN and at HERA, respectively, are also discussed. I conclude that the evidence ...

due to urbanization and consequent environmental problems in iran, many people have been interested in improving the weather quality. lack of information about health risks as a result of pollution is a big obstacle which stops policy-making in this regard. the present study examines the type of relationship between low air quality and tehran citizens’ willingness to pay in order to improve wea...

In the last few years, Run-to-Run (R2R) control techniques have been developed and used to control various processes in industries. These techniques combine response surface, statistical process control, and feedback control techniques. The R2R controller consists of a linear regression model that relates input variables to output variables using Exponentially Weighted Moving Average (EWMA). In...
