In this paper, a new transformerless buck-boost converter based on ZETA converter is introduced. The proposed converter has the ZETA converter advantages such as, buck-boost capability and input to output DC insulation. The suggested converter voltage gain is higher than the classic ZETA converter. In the presented converter, only one main switch is utilized. The proposed converter offers low v...

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...

In this paper, we propose a new method for checking randomness of non-Gaussian stable data based on a characterization result. This method is more sensitive with respect to non-random data compared to the well-known non-parametric randomness tests.

based on the current approach, to ascertain and enforce the sanctions in law is one of the exclusive functions of governments. but the deeper examination reveals that many transactors prefer non-legal sanctions. at first glance, this self-enforcement mechanism seems to be contrary to legal fundamentals. therefore, these sanctions are contested in law. this article is an attempt to consider a ne...

this commentary follows up on an editorial by eyal and colleagues in which these authors discuss the implications of the emergence of non-physician clinicians (npcs) on the health labour market for the education of medical doctors. we generally agree with those authors and we want to stress the importance of clarifying the terminology to describe these practitioners and of defining more formall...
