From August 1939 until January 1941, W. Kreutz did systematical research to the CO2 content of the lower atmosphere for botanical/agricultural purposes, unaware of possible climate issues at that time. He makes a detailed analysis of the relation between weather factors and atmospheric CO2. The remarkable issue is that the average CO2 contents amounts to 438,5 ppmv. Moreover, there is a strong ...

The domain of security standardization within biometrics lacks of a systematical framework approach for evaluation and testing of biometric technology. The international standardization project NP 19792 of the ISO/IEC JTC1/SC27 Information Technology Security Techniques intends to fill this gap for the highly demanded field of IT security biometrics. This paper delivers a first contribution for...

This paper combines the use of the Harris index and the relative damping index (RDI) to give a new method for CPM-based controller tuning. The RDI is defined based on the disturbance impulse response, which is calculated as a byproduct of the Harris index. The proposed technique provides controller settings that attain the best-achievable performance by careful and systematical changing of cont...

An essential problem in the design of holographic algorithms is to decide whether the required signatures can be realized by matchgates under a suitable basis transformation (SRP). For holographic algorithms on domain size 2, [1, 2, 4, 5] have built a systematical theory. In this paper, we reduce SRP on domain size k ≥ 3 to SRP on domain size 2 for holographic algorithms on bases of rank 2. Fur...

Systematical event trace analysis requires both detailed knowledge about the event trace analysis environment used and detailed knowledge about the object system itself. This article presents three important knowledge bases which, when contained in event trace analysis environments, facilitate achieving useful performance results of the system under investigation. ParaGraph — a dedicated event ...

We propose a simple reflection measurement setup and a motion evaluation procedure based on a two dimensional recording of subsequent speckle images. The averaging of cross correlation functions is used to measure displacements. We demonstrate experimentally a 10 nm precision on a 50 μm measurement range limited by systematical errors. An image library is proposed to extend the measurement rang...

BACKGROUND Fractures of the proximal humerus in patients under the age of 18 years show a low incidence; existing clinical studies only comprise small patient numbers. Different treatment methods are mentioned in the literature but a comparison of the outcome of these methods is rarely made. Up to now, no evidence-based algorithm for conservative and operative treatment is available. The aim of...

1092 www.thelancet.com Vol 382 September 28, 2013 could be primarily due to diff erences in estimation methods. Compared with the methods based on direct observation that the four countries used, the GBD 2010 used a fi ve-step approach to estimate alcohol-related transport injury that was based on systematical review and synthesis of published and unpublished data because most countries lack hi...

PURPOSE To evaluate the restorative effectiveness of fiber post versus metal screw post through systematical review. METHODS Randomized controlled trials (RCTs) data from the establishment of the database up to June 2013 were searched from MEDLINE (Ovid), PubMed, The Cochrane Library, Embase, Wanfang Data, VIP, CNKI and CBM using the designed strategy. After data extraction and quality review...

There is a pressing need for long-term, controlled drug release for sustained treatment of chronic or persistent medical conditions and diseases. Guided drug delivery is difficult because therapeutic compounds need to survive numerous transport barriers and binding targets throughout the body. Nanoscale protein-based polymers are increasingly used for drug and vaccine delivery to cross these bi...
