Phase mode analysis of directional elements in a circular array
A technique for analyzing the directional elements of a circular array is presented. The technique is based on phase mode decomposition of measured element patterns. It can be used to calibrate the array and may help identify sources of measurement errors. It is illustrated with patterns from a 108-element circular array.
Constrained sum and difference pattern synthesis for a circular array
A method is presented for synthesizing the constrained sum and difference pattern of a circular array used by a secondary surveillance radar. The technique, based on the sample matrix inversion (SMI) approach, is shown to be considerably more efficient than solving the problem by nonlinear, iterative optimization. It is applied to measured data from a 108-element circular L-band array.
Facilitating Spiritual Care in the Rehabilitation Setting
&NA; Nurses, who traditionally have espoused a holistic approach to patient care, are in a unique position to attend to clients’ spiritual needs. The assessment, planning, and provision of spiritual care is particularly important in the rehabilitation setting. Research attention needs to be directed at gaps in the current state of knowledge and practice of spiritual care to meet the needs of rehabilitation clients.
