Stark effect investigations in the 6, 7 and 8 2 D 3/2,5/2 levels of 85 Rb and the 8, 9 and 10 2 D 3/2,5/2 levels of 133 Cs were performed with the level crossing technique. The levels were populated in a two-step excitation process, involving a CW tunable dye laser. The tensor polarizability of all states was measured and a good agreement with theoretical values, obtained with the Coulomb approxim

Human safety and health, environmental and property protection and security concerning hazardous materials supply chain are important issues for many countries, industries and organisations around the world. This paper presents some key results of a comprehensive risk study on hazardous materials supply chain incidents. Based on a risk analysis framework adapted for mari-time transport of packaged

The incidence and prevalence of heart failure (HF) has increased successively over the past decade. Mortality and morbidity is high. It is the most common cause of hospitalisation in the elderly and has been estimated to account for 1-3% of health care costs in many countries. There is a need therefore, to improve care for HF patients. However, due to limited economic resources, this must be done

The paper considers the implementation of digital controllers as real-time tasks in priority-preemptive systems. The performance of a digital feedback control system depends critically on the timing of its sampling and control actions. It is desirable to minimize the computational delay in the controller, as well as the sampling jitter and the control jitter. It is shown that by scheduling the two

In many fMRI task-evoked studies, localized brain activity can be detected by GLM fitting and statistical hypothesis testing. Statistical parametric mapping (SPM) is the classical method that requires Gaussian pre-smoothing of the data. Instead, the wavelet transform provides a compact representation of activation patterns. Wavelet based SPM (WSPM) is an extension of SPM that combines wavelet proc

Wittgenstein once made a distinction between two uses of "I". The first use, as object, as in "I have broken my arm" or "The wind is blowing in my hair", involves the recognition of a particular person, and there is the possibility of error concerning the identity of the person. In the other use, as subject, as in "I think it will rain" or "I am trying to lift my arm", no person is recognised. No

This paper presents a 0.13/spl mu/m CMOS 1.7GHz VCO with frequency divider, suitable for ultra-low-power hearing-aid applications. The circuit has a 16% tuning range, a minimum power consumption of 320/spl mu/W from a 0.8V power supply, power-supply and temperature compensation, an excellent 188dBc/Hz figure-of-merit without the need of off-chip components, and an area of 0.2mm/sup 2/.
