Supercavitation technology can greatly improve the speed of underwater vehicles by reducing drag. However, time-delay characteristic a supercavitating vehicle presents control challenge. In this paper, linear parameter-varying (LPV) model for is established analysing characteristics planing force. Moreover, considering that cavitation radius easily perturbed external disturbances, LPV delay dep...

Background: The erbium-doped yttrium, aluminum, and garnet (Er:YAG) laser is thought to be the most promising laser for periodontal treatment; however, its application is still under consideration. The aim of this study was to compare Er:YAG laser monotherapy with conventional scaling and root planing (SRP) for chronic periodontitis using clinical parameters, the detection rate of periodontal p...

AIM Root debridement by scaling and root planing may not completely remove contaminated cementum particularly in more apical areas. The smear layer formed during root planing inhibits cell migration and attachment leading to impaired marginal periodontal healing. The present study was done to compare the morphological effects of root surface demineralization using citric acid and EDTA as root-c...

BACKGROUND Glanzmann thrombasthenia (GT) is an exceedingly rare but well-defined inherited disorder of platelet function caused by a defect in the glycoprotein IIb/IIIa complex. The association of GT with consanguinity has been noted, especially in geographic regions in which intermarriage is common. In most patients, GT is diagnosed during early infancy or before the age of 5 years. Common man...

The success of software projects and the resulting software products are highly dependent on the initial stages of the life-cycle process – the inception and elaboration stages. The most critical success factors in improving the outcome of software projects have often been identified as being the requirements negotiation and the initial architecting and planing of the software system. Not surpr...
