Sediment rating curve (SRC) is a conventional and a common regression model in estimating suspended sediment load (SSL) of flow discharge. However, in most cases the data log-transformation in SRC models causing a bias which underestimates SSL prediction. In this study, using the daily stream flow and suspended sediment load data from Shalman hydrometric station on Shalmanroud River, Guilan Pro...
Dynamic modeling and control of dc-dc series resonant converter (SRC) especially when operating in discontinuous conduction mode (DCM) is still a challenge in power electronics. Due to semiconductors switching, SRC is naturally represented as a switched linear system, a class of hybrid systems. Nevertheless, the hybrid nature of the SRC is commonly neglected and it is modeled as a purely contin...
ظرفیت نگهداری حلال آرد (Solvent retention capacity)، وزن حلال نگهداری‌شده توسط آرد پس از سانتریفیوژ است که براساس درصد وزن آرد دارای 14 درصد رطوبت بیان می‌شود. الگوی ترکیبی چهار مقدار SRC، وضعیت آرد از نظر کیفیت و خواص عملکردی را تعیین می‌کند. ظرفیت نگهداری حلال روشی سهل، اقتصادی و کاربرپسند است. فناوری SRC بر پایه‌ی انرژی و نه سینتیک بنا شده است. در مقابل، آزمون‌های رئولوژیکی خمیر، بر پایه‌ی س...
Estimation of sediment loads in rivers is one of the most important, difficult components of sediment transport studies and river engineering. Accessing new methods that can be effective in this background are more important. In this research, we have used the artificial neural network (ANN) to optimize the results of the sediment rating curve (SRC) to predict the suspended sediment loads. For ...
The estimation of the correct amount of suspended sediment has an important role in the optimal design of water structures, erosion studies and water quality studies. The sediment rating curve (SRC) is a conventional and well-known regression model. However, due to logarithmic transformations in calibrating this model, its estimated values are often less than actual values. In the present s...

This article presents the probability of ruin for classical risk process by including density function claims which satisfies a mixed linear exponential family. can be defined as , where src=image/13428362_02.gif>, src=image/13428362_03.gif>, src=image/13428362_20.gif> is positive integer with src=image/13428362_04.gif> src=image/13428362_05.gif>, src=image/134283...
An assignment of intergers to the vertices a graph subject certain constraints is called vertex labeling src=image/13424638_01.gif>. Different types techniques are used in field coding theory, cryptography, radar, missile guidance, src=image/13424638_02.gif>-ray crystallography etc. A DCL bijective function src=image/13424638_03.gif> from node set src=image/13424...
در این پایان نامه سعی خواهد شد حلقه های موضعی جابه جایی را مشخص کنیم که حلقه ی ماتریس های n×n روی آنها قویاً تمیز باشند. روند کار براساس تجزیه در[ r[t است.همچنین نشان می دهیم برای هر چندجمله ای تکین f متعلق به[ r[t قویاً تمیز بودن ماتریس همراه چندجمله ای f معادل است با اینکه همه ی ماتریس هایی با چندجمله ای مشخصه ی f قویاً تمیز باشند.در ادامه با معرفی( src(sr- تجزیه ها ارتباط میان src -تجزیه ها وم...
The aim of this study was to estimate suspended sediment by the ANN model, DT with CART algorithm and different types of SRC, in ten stations from the Lorestan Province of Iran. The results showed that the accuracy of ANN with Levenberg-Marquardt back propagation algorithm is more than the two other models, especially in high discharges. Comparison of different intervals in models showed that r...
