Two class-D RF power amplifiers consisting of CMOS inverter chains have been designed and measured. The first amplifier operates at 1GHz and has a maximum output power of 12dBm, whereas the second operates at 1.5GHz and outputs a maximum of 6dBm. The amplifiers have been characterized for use in two different polar transmitter architectures, Pulse Width Modulation by Variable Gate Bias (PWMVGB) an
The high-energy satellite of the L2,3 X-ray emission band in Na, Mg, Al and Si has for a long time been attributed to the decay of an initial state with two holes in the 2p shell. In particular, the satellite threshold has been assigned to an initial (2p2)1D state. It has recently been found that X-ray and Auger data give two different values for the energy of this doubly-ionized state, and attemp
Abstract in Undetermined Increased global competition demands for increased manufacturing costs awareness. Maintenance activities and strategies have been studied extensively, but few studies discuss maintenance costs. This paper presents a model for calculating performance-driven manufacturing costs (in currency/piece), including parameters for determining the maintenance costs in relation to the
Cycle-resolved wall temperature measurements have been performed in a one-cylinder, port-injected optical Scania D12 truck engine run in HCCI mode. Point measurements at various locations were made using Laser-Induced Phosphorescence (LIP). Single point measurements with thermographic phosphors utilize the temperature dependency of the phosphorescence decay time. The phosphorescence peak at 538 nm
Regarding access to remote sensing data, there are a number of aspects that need to be taken into consideration such as user time limit for e.g. space scientists, what rights do the involving states have, access rights for foreign domains and archiving. But the most central aspect is perhaps the pricing of such information. The demand for remote sensing data creates a competitive market, a market
Aims: To analyse which factors influence nursing home placement (NHP) and time until NHP in long-term cholinesterase inhibitor treated patients with Alzheimer’s disease (AD). Methods: The Swedish Alzheimer Treatment Study (SATS) is an open, on-going, non-randomized, multicentre study in a routine clinical setting. Patients with the diagnosis of AD, living at home at the time of inclusion, receive
