The solar photovoltaic (PV) industry in the United States has been the recipient of billions of dollars of subsidies at the federal and state level, often motivated by environmental externalities and dynamic spillovers from learning-by-doing in the installation of the technology. This paper investigates cost reductions due to learning-bydoing (LBD) using comprehensive data on all solar PV insta...

MAGNETIC RESONANCE IMAGING: PROCESS AND RISKS Medical diagnostics has made furious progress in recent decades. This development is one of the main reasons why a whole series of malignant diseases can now be identified at an early stage, thus considerably increasing the chances of recovery. Large arrays of apparatus are often required for this, not only in clinics, but also in the practices of t...

This paper presents a solution for automating dual boot Linux and Windows NT 4.0 installations on a PC. The process is automated to the extent that one starts with a PC with a blank hard disk and ends up with a fully customized dual-boot PC. The process involves booting a PC with a floppy disk; choosing what kin of system is required from a menu and then, once the install begins, popping out th...

70% of the patients affected by PSP are not correctly diagnosed in the first 2 to 3 years of the disease. I personally have followed three patients who at CT presented the features of PSP while none of them showed clinical signs definitively suggestive of the disease. This suggests that the CT findings could be present before the complete clinical manifestation of the syndrome, at least in a nu...

A basic assumption often made in risk/reliability based inspection planning is that a Bayesian approach can be used. This implies that probabilities of failure can be updated in a consistent way when new information (from inspections and repairs) becomes available. The Bayesian approach and a no-crack detection assumption implies that the inspection time intervals usually become longer and long...

The number of installations of the Spin model checking tool is steadily increasing. There are well over two thousand installations today, divided roughly evenly over academic and industrial sites. The tool itself also continues to evolve; it has more than doubled in size, and hopefully at least equally so in functionality, since it was rst distributed in early 1991. The tool runs on most standa...
