In this research, the application of multilayer perceptron (MLP) neural networks and support vector machine (SVM) for modeling the hydrodynamic behavior of Permeable Breakwaters with Porous Core has been investigated. For this purpose, experimental data have been used on the physical model to relate the reflection and transition coefficients of incident waves as the output parameters to the wid...
The main objective of this paper consists of the state look-ahead path and the counting path. The proposed counter is a single mode counter, which sequences through a fixed set of pre assigned count states, of which each next count state represents the next counter value in sequence. The counter is partitioned into uniform 2-bit synchronous up counting modules. Next state transitions in countin...
We conducted the measurement of the hardness-depth relationship of NiTi shape memory alloy with a sharp Berkovich indenter. Different from most ductile metals, NiTi reacts to the mechanical load of indentation through phase transition underneath the indentation tip. We found that the hardness decreases rapidly with the increase of the indentation depth and eventually approaches a constant. To u...
پوششهای tbc یکی از جدیدترین و پیشرفته ترین پوششهایی است که امروزه در توربینهای گازی نیروگاهها و توربینهای هواپیماها استفاده می شود. این پوششها با ایجاد اختلاف دما در حدود 100 تا 150 درجه سانتیگراد، باعث افزایش عمر سوپرآلیاژهای قطعات داغ و نیز باعث صرفه جویی چشمگیری در مصرف سوخت نیروگاهها و هواپیماها می گردد. در این تحقیق، بحث و بررسی در مورد علل تخریب پوششهای tbc در لاینرها و قطعات transition p...
Through a detailed analysis of seismicity at the base of the transition zone, we obtain an updated value of the maximum reliable depth of confirmed seismicity, we investigate regional variation in the maximum depth of seismicity among those Wadati-Benioff zones which reach the bottom of the transition zone, and we attempt to quantify the maximum possible rate of seismic release in the lower man...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
abstract the variables affecting the nature of reading comprehension can be classified into two general categories: reader’s variables, and text variables (alderson, 2000). despite the wave of research on vocabulary knowledge as reader’s variable, the role of this knowledge in c-test as a text-dependent test and its interaction with lexical cohesion of the test as a text feature has remained a...
The n-tree approximation scheme, introduced in the context of random directed polymers, is here applied to the computation of the maximum Lya-punov exponent in a coupled map lattice. We discuss both an exact implementation for small tree-depth n and a numerical implementation for larger ns. We find that the phase-transition predicted by the mean field approach shifts towards larger values of th...
for any educational program to be successful, many factors work hand in hand. based on pervious efl studies, teachers and learners are the keys to gain achievement. granted the fact that explicit and implicit practice plays a key role in education, knowledge of it can help teachers facilitate students’ vocabulary learning. this study investigated to determine the contribution of explicit and i...
