Does Low Cost Large Panel Processing mean Low Performance?

The Large Area Processing for thinfilm substrates can be used to reduce the cost per layer per area significantly. Various process setups exist to achieve this goal, and they differ in terms of process tolerances and cost. As different process tolerances result in different performance tolerance bands of the produced structures, customers may want to chose the right process to obtain sufficient...

Does Low Surface Brightness Mean Low Density?

We compare the dynamical properties of two galaxies at identical positions on the Tully-Fisher relation, but with different surface brightnesses. We find that the low surface brightness galaxy UGC 128 has a higher mass-to-light ratio, and yet has lower mass densities than the high surface brightness galaxy NGC 2403. This is true for the gas surface density, the stellar surface density, and the ...

Low carbohydrate does not mean low glycaemic index!

Dumesnil et al. (2001) reported the results of a study from Laval University, Québec, in which overweight men were fed under metabolic ward conditions for 6 d on each of three different test diets. They concluded that: ‘. . . a lowglycaemic index–low-fat–high-protein diet can produce a marked decrease in ad libitum energy intake without increasing hunger or decreasing satiety while having rapid...

Planning the Behaviour of Low-Cost Quadcopters for Surveillance Missions

Micro Aerial Vehicles (MAVs) are increasingly regarded as a valid low-cost alternative to UAVs and ground robots in surveillance missions and a number of other civil and military applications. Research on autonomous MAVs is still in its infancy and has focused almost exclusively on integrating control and computer vision techniques to achieve reliable autonomous flight. In this paper, we descri...

Does Test Preparation Mean Low - Quality Instruction ?

Critics of test-based accountability warn that test preparation has a negative influence on teachers’ instruction due to a focus on procedural skills. Others advocate that the adoption of more rigorous assessments may be a way to incentivize more ambitious test-preparation instruction. Drawing on classroom observations and teacher surveys, we do find that testpreparation activities predict lowe...
