‎In this paper we consider the special classes of Sonnenschein matrices‎, ‎namely the Karamata matrices $K[alpha,beta]=left(a_{n,k}right)$ with the entries‎ ‎[{a_{n,k}} = sumlimits_{v = 0}^k {left( begin{array}{l}‎ ‎n\‎ ‎v‎ ‎end{array} right){{left( {1‎ - ‎alpha‎ - ‎beta } right)}^v}{alpha ^{n‎ - ‎v}}left( begin{array}{l}‎ ‎n‎ + ‎k‎ - ‎v‎ - ‎1\‎ ‎,,,,,,,,,,k...

antenna structures with low side lobe levels are normally the main goal during antenna design. in this paper, a new method for reduction of radiation pattern side lobe level in phased array antenna with uniform and non-uniform weighting is presented. in this method, by changing the array elements weight or adding several elements, such as slc technique, the pattern with low side lobe level can ...

a 56-year-old man with a two year history of chronic stable angina underwent elective coronary artery bypass grafting (cabg) due to angiographic report of three vessel disease and tight stenosis at proximal part of left anterior descending artery (lad). while harvesting of radial artery (ra), the distal half of radial artery was found to bifurcate to two parallel branches with equal size. we us...

background: disorders of sex development (dsds) belong to uncommon pathologies and result from abnormalities during gonadal determination and differentiation. various gene mutations involved in gonadal determination and differentiation have been associated with gonadal dysgenesis. despite advances in exploration of genes and mechanisms involved in sex disorders, most children with severe 46,xy ...

The HARP (Heterodyne Array Receiver Programme) B-band camera will incorporate a focal-plane array of 16, 850 micron (325-375 GHz), SIS heterodyne detectors. This receiver has been commissioned for use on the James Clerk Maxwell Telescope in Hawaii. The complete instrument will o er greatly improved spectroscopic mapping speeds (>x10) of extended objects complementing existing continuum bolomete...

This paper reports a novel actuating design that uses the shear deformation of a piezoelectric actuator to deflect a bulge-diaphragm for driving an array microdroplet ejector. In essence, we employed a circular-shaped actuator poled radial direction with remnant polarization normal to the actuating electric field for inducing the piezoelectric shear effect. The array microdroplet ejector consis...

A Phased Array Doppler Sonar (PADS), as developed at SIO, images both acoustic backscatter intensity and Doppler shift over areas up to 90 degrees in bearing by 500 m in range. Sequences of images are recorded continuously for up to two months, with individual “pings” 0.5 to 1.0 seconds apart. The images permit two independent estimates of the mean velocity to be formed over the imaged area: on...

This paper proposes a novel signal-detection-theory-based definition for the resolution of Neuromagnetic imaging systems, and develops a Monte Carlo computer simulation method to compute the resolution. Using the resolution as a performance measure, the performance of various types of sensor hardware is assessed. The assessments include performance improvements due to the increase in the number...

We report the jet width profile of of the nearby (∼30 Mpc) AGN NGC 4261 for both the approaching jet and the counter jet at radial distances ranging from ∼103–109 Schwarzschild radius (RS) from the central engine. Our Very Large Array (VLA) and Very Long Baseline Array (VLBA) observations reveal that the jets maintain a conical structure on both sides over the range 103–109 RS without any struc...

In this paper, the subdomain analysis model of eddy current brake (ECB) is established. By comparing with finite element method, accuracies and are verified. Furthermore, resistance characteristics radial, axial, Halbach arrays under impact load calculated compared. The axial array has a large braking force coefficient but low critical velocity. radial high advantages first two arrays. Not only...
