The surface cold working (SCW) of austenitic stainless steel (SS) causes martensitic transformation in the layers, and percentage fraction strain-induced martensite depends on degree SCW. Higher content α′−martensite increases micro-hardness fatigue strength, but deterioration corrosion resistance is possible. Therefore, desired operational behaviour SS can be ensured by corresponding SCW heat ...

The main objective of this study was to investigate the effect of income smoothing on investors reaction to Earnings Persistence of companies listed on the Stock Exchange in Tehran. The population of the study was companies listed on the Stock Exchange in Tehran, the sample size due to screening method and after removing outliers is equal to 118 companies. In this study, earnings persistence an...

Simple exponential smoothing (SES) methods are the most commonly used methods in forecasting and time series analysis. However, they are generally insensitive to non-stationary structural events such as level shifts, ramp shifts, and spikes or impulses. Similar to that of outliers in stationary time series, these non-stationary events will lead to increased level of errors in the forecasting pr...

This letter presents a novel C-band rectifier that is capable of handling high input power. The consists Schottky diode, an impedance matching circuit with compensation microstrip structure, and output filter harmonic suppression ripple smoothing. experimental results indicate the yields conversion efficiency exceeding 70% peak 74.1% over wide power range 20 to 26 dBm (6 dB) at 5.8 GHz, utilizi...

A power conversion interface for a small-capacity photovoltaic generation system (PPGS) is proposed in this paper. The composed of DC–DC converter (DDC), battery pack and buck–boost inverter (BBI). integrated to the store or release energy smoothing fluctuation PPGS. only activated when large change occurs array (PV array). DC power, no matter whether from PV pack, needs be converted into AC by...

conclusions the use of smoothing methods helps us to eliminate non-linear effects but it is more appropriate to use cox proportional hazards model in medical data because of its’ ease of interpretation and capability of modeling both continuous and discrete covariates. also, cox proportional hazards model and smoothing methods analysis identified that age at diagnosis and tumor size were indepe...

floorplanning is an important step in physical design of vlsi circuits. it is used to plan the positions of a set of circuit modules on a chip in order to optimize the circuit performance. however, modern floorplanning takes better care of providing extra options to place dedicated modules in the hierarchical designs to align circuit blocks one by one within certain bounding box for helping seq...

Rotational smoothing is a phenomenon consisting in gain of regularity by means averaging over rotations. This present operators that regularize only certain directions, contrast to regularizing all directions. The the result rotating directions where corresponding operator performs effect. In this paper we carry out systematic study rotational for class includes k-vector-space Riesz potentials ...
