Corrosion Control of Subsea Production Control Systems: Twenty Years' Experience

Simulation of subsea control systems

The pumping system is modelled as shown in Figure 3. Please note that it is an advantage to limit the size of the model by leaving out components which are not active in the sequences that we will be looking at. This is because all of the elements included in a model are included in the calculations, taking up part of our computer’s capacity. This is also the case for passive components such as...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

A Multivariate Quality Control Procedure in Multistage Production Systems

In this paper a multivariate quality control procedure is offered in which several correlated stages are present in production systems and in each stage there are several correlated control variable. Using Hotelling's T2 statistic, first, each stage is tested for being out of control. Then out of control variables are selected using Murphy's method. The remainder of the research involves evalua...

Hesburgh: still in control after twenty-five years

SOUTHBEND, Ind. [AP] Practic­ ing the virtue of hum ility, the Rev. Theodore M. Hesburgh submits his resignation as president of the University of Notre Dame once a year. But it hasn’t been accepted yet and isn’t likely to be accepted soon. Now in his 25th year at the helm of the nation’s best-known Catholic university, Hesburgh qualifies as dean of university presidents across the country. “ T...
