Hydrologic Network Design Formulation

New MILP Formulation for Instrumentation Network Design and Upgrade

The problem of instrumentation network design and upgrade consists of determining the optimal set of instruments to obtain sufficiently accurate and reliable estimates of ®ariables. An existing formulation of the cost optimal sensor network design and up( ) grade problem Bagajewicz, 1997 is in the form of a mathematical programming problem, but it has the disad®antage that the constraints are n...

Impact of Streamflow Persistence on Hydrologic Design

Conventional methods for estimating the average return period, E(T), and failure risk, R, generally ignore the impact of persistence in annual streamflows on associated probabilistic statements and streamflow statistics. Recent evaluations of streamflow observations indicate statistically significant serial correlations ~persistence! associated with annual low flows in the United States. We def...

Ofloxacin Ocular Inserts: Design, Formulation and Evaluation

In developing a drug delivery strategy, issues of absorption, distribution, metabolism, and elimination must be considered. The eye presents unique opportunities and challenges when it comes to the delivery of pharmaceuticals. While absorption by this route is bungling, there are few side effects with conventional ocular dosage forms. Hence, ocular inserts were prepared with prolonged release o...

طراحی تلفن های داخلی تحت شبکه ip design pabx under network ip

برای اینکه یک ارتباط تلفنی ساده بین مبدا و مقصد برقرار شود نیاز به تجهیزاتی از قبیل گوشی تلفن مشترک a ، کابل جهت ارتباط با مرکز سوئیچینگ ، گوشی تلفن مشترک b ، اگر هر دو مشترک a و b در یک ناحیه نباشند در اینصورت نیاز به تجهیزات transmission که در مخابرات به قسمت pcm مشهور است . حال در نظر بگیرید مشترک a بخواهد با مشترک b تماس بگیرد چه کسی مشترک b را خبر می کند یا وقتی مشترک b گوشی را برمی دارد چ...
