A novel comb compensator with a good passband deviation-complexity tradeoff
This paper presents a novel simple multiplierless comb compensator which exhibits a good tradeoff between the resulting passband droop compensation and introduced complexity. The filter is composed of two second order sections, both working at the lowest rate, and with sine squared magnitude characteristics. The first section remains the same for all comb parameters. The second section depends only on the number of the cascaded comb filters. A simple formula which relates compensator parameter and the number of cascaded combs, is derived. The comparisons with some known compensators are also provided in order to demonstrate the benefit of the proposed compensator.
Design of multiplierless comb compensators with magnitude response synthesized as sinewave functions
This paper presents a research on design of multiplierless comb compensators
 with magnitude response synthesized as sinewave functions. First, it is
 elaborated the importance of comb decimation filter and why we need its
 compensator. In continuation are presented some favorable characteristics of
 comb compensator. The compensators, with magnitude characteristic
 synthesized as sinewave functions fulfill those favorable characteristics.
 Next, are described some most important results on design of compensators
 with sinewave-based magnitude responses including single and cascaded
 sinewave-based functions. In all designs are presented the overall
 corresponding magnitude responses and the zooms in the passband. The
 parameters of design generally depend only on number of cascaded combs and
 generally do not depend on decimation factor. Design parameters are
 presented in tables along with the corresponding required number of adders.
Complex thoracic vascular injury repair using deep hypothermia and circulatory arrest.
A 61-year-old man with a penetrating injury to the innominate artery, left common carotid artery, and left subclavian artery at their origins from the aortic arch with associated injuries to both innominate veins and an innominate artery to vein fistula after a single stab wound is described. The patient was managed successfully using cardiopulmonary bypass together with deep hypothermia and circulatory arrest. Presentation and management are discussed.
