<abstract><p>In this article, we make mathematical and practical contributions to the Bell-X family of absolutely continuous distributions. As a main member family, special distribution extending modeling perspectives famous Burr XII (BXII) is discussed in detail. It called Bell-Burr (BBXII) distribution. stands apart from other extended BXII distributions because its flexibility te...

This paper proposes an approach which simultaneously considers the properties of cost and quality based on the Burr distribution to determine three parameters (including sample size, sampling interval between successive samples, and the control limits) when an x-bar chart monitors a manufacturing process with Weibull failure characteristic and non-normal data. Also, the cost model of Banerjee a...

The drilling and riveting processes are widely used in the assembly of carrier rocket, which makes the efficiency and quality of drilling become the important factor affecting the assembly process. According to the problem existing in the drilling of thick stacked plate (thickness larger than 10mm) of carrier rocket, such as drill break, large noise and burr etc., experimental study of the infl...

AIM To compare the rates of recurrence of chronic subdural hematoma following surgical evacuation by one of two methods, namely, using frontal and parietal burr holes without a drain or a single parietal burr hole with the addition of a subdural drain. MATERIAL AND METHODS This was a randomized controlled trial with two groups of 70 patients each. Patients in group I had two burr holes and th...

PURPOSE: Tracked navigation systems are generally impractical in bedside neurosurgical procedures, such as a twist-drill crainiostomy for the removal of a subdural hematoma, where the use of navigation could optimize the placement of the drill in relation to the underlying fluid. We use the Microsoft HoloLens to display a hologram floating in the patient’s head to mark a burr hole on the skull....
