A diode-pumped LPE-grown Yb:KYW planar waveguide laser is demonstrated in a microchip monolithic cavity configuration. Output powers as high as 148 mW and thresholds as low as 40 mW were demonstrated during continuous-wave operation. Pulses of 170 ns duration with maximum pulse energy of 44 nJ at a 722 kHz repetition rate were generated when Q-switched using a semiconductor saturable absorber m...

The problem of routing military convoys between specific origin and destination pairs is known as convoy movement problem (CMP). In this study, we consider an existing mathematical model of CMP and propose a lower bounding procedure based on Lagrangean Relaxation. The robustness of the proposed procedure is evaluated on a variety of test problem instances. Encouraging results are obtained. Jour...

This paper describes a multiband vector quantization (VQ) technique based on inner product for wideband speech coding at 16 kb/s. Our approach consists of splitting the input speech into two separate bands and then applying an independent coding scheme for each band. A code excited linear prediction (CELP) coder is used in the lower band while a transform based coding strategy is applied in the...

We assessed the effectiveness of secondary prevention of coronary heart disease (CHD) in primary care, in a cross-sectional study of 1015 patients aged < 75 years with documented CHD. Patients records were examined for documentation of CHD risk factors; 722 patients then attended education sessions where blood pressure and cholesterol were measured, a supervised questionnaire detailing modifiab...
