a study on thermodynamic models for simulation of 1,3 butadiene purification columns

attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...

Estimation Efficiency Under Privacy Constraints

We investigate the problem of estimating a random variable Y ∈ Y under a privacy constraint dictated by another correlated random variable X ∈ X , where estimation efficiency and privacy are assessed in terms of two different loss functions. In the discrete case, we use the Hamming loss function and express the corresponding utility-privacy tradeoff in terms of the privacy-constrained guessing ...

the study of practical and theoretical foundation of credit risk and its coverage

پس از بررسی هر کدام از فاکتورهای نوع صنعت, نوع ضمانت نامه, نرخ بهره , نرخ تورم, ریسک اعتباری کشورها, کارمزد, ریکاوری, gdp, پوشش و وثیقه بر ریسک اعتباری صندوق ضمانت صادرات ایران مشخص گردید که همه فاکتورها به استثنای ریسک اعتباری کشورها و کارمزد بقیه فاکتورها رابطه معناداری با ریسک اعتباری دارند در ضمن نرخ بهره , نرخ تورم, ریکاوری, و نوع صنعت و ریسک کشورها اثر عکس روی ریسک اعتباری داردو پوشش, وثی...

Evaluating the efficiency of targeted designs for randomized clinical trials.

PURPOSE Genomic technologies make it increasingly possible to identify patients most likely to benefit from a molecularly targeted drug. This creates the opportunity to conduct targeted clinical trials with eligibility restricted to patients predicted to be responsive to the drug. EXPERIMENTAL DESIGN We evaluated the relative efficiency of a targeted clinical trial design to an untargeted des...
