Dual Half-Integrality for Uncrossable Cut Cover and Its Application to Maximum Half-Integral Flow
Get PDFGiven an edge weighted graph and a forest F, the 2-edge connectivity augmentation problem is to pick a minimum weighted set of edges, E', such that every connected component of E' ∪ F is 2-edge connected. Williamson et al. gave a 2-approximation algorithm (WGMV) for this problem using the primal-dual schema. We show that when edge weights are integral, the WGMV procedure can be modified to obtain a half-integral dual. The 2-edge connectivity augmentation problem has an interesting connection to routing flow in graphs where the union of supply and demand is planar. The half-integrality of the dual leads to a tight 2-approximate max-half-integral-flow min-multicut theorem
Design and analysis of a soft spiral gripper
Get PDFContinuum robots have been gaining popularity in recent years for their umpteen advantages. Soft robots are a class of continuum robots which are made of squishy materials which have the added benefit of being innocuous to humans. Soft robotic grippers are one of the major application of soft robots as they have the ability to conform and adapt their structure to the object to be grasped. This work presents a bio-inspired technique to increase contact area while grasping and handling long slender objects by helically twisting around them. An embodiment of such a spiral gripper utilizes unique configurations of pneumatically actuated Fiber Reinforced Elastomeric Enclosures which has a range of motions like extension, rotation, contraction. This work presents a detailed analysis technique using Cosserat beam theory to estimate the normal contact force exerted by the spiral gripper on cylindrical objects.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2018-12-01The student, Naveen Kumar Uppalapati, accepted the attached license on 2016-12-06 at 09:16.The student, Naveen Kumar Uppalapati, submitted this Thesis for approval on 2016-12-06 at 09:27.This Thesis was approved for publication on 2016-12-06 at 14:34.DSpace SAF Submission Ingestion Package generated from Vireo submission #10442 on 2017-02-28 at 14:43:14Made available in DSpace on 2017-03-01T17:02:04Z (GMT).

Patriarchy, Superstition and the Feminisation of Evil
No full textThis chapter critically examines how patriarchal ideologies and superstitions intersect to make women the primary targets of witchcraft accusations. Focusing on the cultural and societal mechanisms that frame the concept of evil through a gendered lens, this analysis reveals how patriarchal control is exercised by casting women as scapegoats for malevolent forces
