When the input inductor operates in discontinuous current mode (DCM), Cuk converter can automatically achieve power factor correction (PFC) function with only a simple voltage control loop. However, conventional PFC suffers from high intermediate capacitor because of lack feedback and relatively low (PF). In this paper, using variable which varies transient rectified is proposed to enhance PF r...

The deployment of machine learning classifiers in high-stakes domains requires well-calibrated confidence scores for model predictions. In this paper we introduce the notion variable-based calibration to characterize properties a with respect variable interest, generalizing traditional score-based metrics such as expected error (ECE). particular, find that models near-perfect ECE can exhibit si...

Abstract Infinitely variable transmission (IVT) is a system which delivers the ratio between two turning elements to continuous (non-discrete) variation (including zero). This article uses Solidworks software build and simulate cam-based IVT system. There are identical units in under examination. Each unit comprises cam with an oscillating slot connection that swings on hinge can be vertically ...

based on symbolic manipulation program maple and using riccati equation mapping method several explicit exact solutions including kink, soliton-like, periodic and rational solutions are obtained for (2+1)-dimensional variable coefficient broer--kaup system in quite a straightforward manner. the known solutions of riccati equation are used to construct new solutions for variable coefficient broe...

In this paper, a new method for estimating the linear regression coefficients approximation is presented based on Z-numbers. In this model, observations are real numbers, regression coefficients and dependent variables (y) have values ​​for Z-numbers. To estimate the coefficients of this model, we first convert the linear regression model based on Z-numbers into two fuzzy linear regression mode...

Cultural awareness is important for a range of operations from disaster assistance to active conflict. This paper illustrates the application of an acknowledged system of systems (SoS) to train dismounted soldiers in cultural awareness. Such training system is required to not only increase intelligence gathering opportunities but also minimize troop member loss during missions. Moreover, given ...
