Das Thema „Erfolgsnachweis des Bürosystem-Einsatzes“ ist sowohl in der Wissenschaft als auch in der Praxis seit vielen Jahren Gegenstand der Diskussion. Beiträge, die sich um das Wechselspiel von Potentialerwartungen und Zielerreichung ranken, sind hingegen rar. Es finden sich insgesamt wenig Untersuchungen zu begleitender oder nachträglicher Bewertung des Bürosystem-Einsatzes. Die wenigen, die sich in systematischer Weise mit dem Einsatz und Erfolg auseinandersetzen, basieren wiederum jeweils auf den unterschiedlichen Bezugspunkten, Erfahrungs- und Handlungsbezügen der einzelnen Autoren. In diesem Feld sind mit unterschiedlichen Interessen Technik-Anbieter wie auch Beratungshäuser und DV-/Organisationsabteilungen der Anwenderunternehmen selbst tätig.
Bifacial photovoltaic (PV) modules are able to utilize light from both sides and can therefore significantly increase the electric yield of PV power plants, thus reducing the cost and improving profitability. Bifacial PV technology has a huge potential to reach a major market share, in particular when considering utility scale PV plants. Accordingly, bifacial PV is currently attracting increasing attention from involved engineers, scientists and investors. There is a lack of available, structured information about this topic. A book that focuses exclusively on bifacial PV thus meets an increasing need. Bifacial Photovoltaics: Technology, applications and economics provides an overview of the history, status and future of bifacial PV technology with a focus on crystalline silicon technology, covering the areas of cells, modules, and systems. In addition, topics like energy yield simulations and bankability are addressed. It is a must-read for researchers and manufacturers involved with cutting-edge photovoltaics.

Radiotherapy (RT) treatment planning is based on computed tomography (CT) images and traditionally uses the conventional Hounsfield unit (CHU) range. This HU range is suited for human tissue but inappropriate for metallic materials. To guarantee safety of patient carrying implants precise HU quantification is beneficial for accurate dose calculations in planning software. Some modern CT systems offer an extended HU range (EHU). This study focuses the suitability of these two HU ranges for the quantification of metallic components of active implantable medical devices (AIMD). CT acquisitions of various metallic and non-metallic materials aligned in a water phantom were investigated. From our acquisitions we calculated that materials with mass-density ρ > 3.0 g/cm3 cannot be represented in the CHU range. For these materials the EHU range could be used for accurate HU quantification. Since the EHU range does not effect the HU values for materials ρ < 3.0 g/cm3, it can be used as a standard for RT treatment planning for patient with and without implants.
