Ca II K spectroheliograms for studies of long-term changes in solar irradiance [PDF]
, 2018 We address the importance of historical full disc Ca II K spectroheliograms for solar activity and irradiance reconstruction studies. We review our work on processing such data to enable them to be used in irradiance reconstructions.

Evolution of the solar irradiance during the Holocene [PDF]
, 2011 Aims. We present a physically consistent reconstruction of the total solar irradiance for the Holocene. Methods. We extend the SATIRE models to estimate the evolution of the total (and partly spectral) solar irradiance over the Holocene.

The Breast, 2017 Decreasing the burden of radiation therapy (RT) for breast cancer includes, next to complete omission, several ways to tailor the extent of RT. Possible options for this include lowering of the total dose, such as selective omission of the boost, hypofractionated RT to shorten the duration of treatment, the selective introduction of partial breast ...

Performance Analysis of a Maximum Power Point Tracking Technique using Silver Mean Method
Advances in Electrical and Electronic Engineering, 2018 The proposed paper presents a simple and particularly efficacious Maximum Power Point Tracking (MPPT) algorithm based on Silver Mean Method (SMM). This method operates by choosing a search interval from the P-V characteristics of the given solar array ...

Fractal Generalized Zone Plates [PDF]
, 2008 The construction of fractal generalized zone plates (FraGZPs) from a set of periodic diffractive optical elements with circular symmetry is proposed. This allows us to increase the number of foci of a conventional fractal zone plate (FraZP), keeping the ...
