PRIORITY MECHANISM DESIGN FOR INCOMING TRAFFIC IN 4G LTE NETWORK

Long Term Evolution (LTE) is currently being used for commercial networks and the same technology will also be used for Public Safety (PS) applications. As a way to maximize network usage and also to allow PS users to share the commercial networks especially during emergency or disaster situations, PS users need to co-exist with commercial users in a shared network environment. To ensure proper assignment of resources in a network originated call scenario, priority mechanisms have been proposed in this report. Priority mechanism in terms of assignment of resources for the user plane, for scheduling of resources in the control plane, and for meeting Quality of Service (QoS) requirements have been discussed. To provide priority treatment, the use of a new parameter named Call Priority Number (CPN) generated by the Policy control and Charging Rules Function (PCRF) is proposed. This parameter signifies the priority of a call in terms of the caller priority, the callee priority and the priority of the application. For incoming calls, the functionality of providing priority mechanism for resource assignment using CPN is proposed to be in the Mobility Management Entity (MME). The functionality for scheduling resources in the control plane, for performing paging, for priority mechanism functionality that uses CPN and the implementation of using different paging cycles for the users based on their priority resides in the evolved NodeB (eNodeB). For managing the priority based on QoS, a mapping of the priority of applications served by LTE networks to the Differentiated Services has been proposed. The mapping can be implemented in the Packet data network Gate Way (PGW). The proposals are verified by simulation. The results show that the PS users are assigned the x required resources for the user plane, they get prioritized QoS treatment within the LTE network, and the PS users are given higher priority over the commercial users. As a result of the techniques proposed in this report, the time it takes to set up a call between PS users is reduced, the number of dropped calls for the PS user decrease, and the PS users have a faster access to network resources.M.S. in Electrical Engineering, December 201

Synthesis, characterization and antimicrobial screening of novel quinoline-thiazole derivatives

508-5132-Chloroquinoline-3-carbaldehyde 1 reacts with 2-cyanoacetohydrazide in ethanol to result in 1-[1-aza-2-(2-chloro(3-quinolyl))vinyl]-2-cyanoacetamide 2. Phenyl isothiocyanate added to a stirred solution of compound 2, sulphur and triethylamine in a mixed solvent of dimethylformamide : ethanol to result in N-[1-aza-2-(2-chloro(3-quinolyl))vinyl](4-amino-3-phenyl-2-thioxo(1,3-thiazoline-5-yl)) carboxamide 3. Compound 3 reacts with different aldehydes in ethanol to yield {4-[1-aza-2-(aryl)vinyl]-3-phenyl-2-thioxo(1,3-thiazolin-5-yl)}-N-[1-aza-2-(2-chloro(3-quinolyl))vinyl]carboxamides 4a-l. These newly synthesized compounds 4a-l have been screened for their antibacterial activity on Escherichia coli, Pseudomonas aeruginosa, Staphylococcus aureus and Streptococcus pyogenes, and antifungal activity on Candida albicans, Aspergillus niger and Aspergillus clavatus

Persistent mullerian duct syndrome in a patient with bilateral cryptorchid testes with seminoma

Persistent mullerian duct syndrome (PMDS) is a rare form of male pseudohermaphroditism in which mullerian duct derivatives are present in an otherwise normally differentiated 46 XY male. We report a case of a 33-year-old male with PMDS operated for postchemotherapy seminoma. A diagnosis of PMDS was made on subsequent histopathological evaluation

Surgical management of early and late ureteral complications after renal transplantation: Techniques and outcomes

© 2014 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd. Background: In this study, we present our experience with ureteral complications requiring revision surgery after renal transplantation and compare our results to a matched control population. Methods: We performed a retrospective analysis of our database between 1997 and 2012. We divided the cases into early (\u3c60 d) and late repairs. Kaplan-Meier and Cox proportional hazards models were used to compare graft survival between the intervention cohort and controls generated from the Scientific Registry of Transplant Recipients data set. Results: Of 2671 kidney transplantations, 51 patients were identified as to having undergone 53 ureteral revision procedures; 43.4% of cases were performed within 60 d of the transplant and were all associated with urinary leaks, and 49% demonstrated ureteral stenosis. Reflux allograft pyelonephritis and ureterolithiasis were each the indication for intervention in 3.8%; 15.1% of the lesions were located at the anastomotic site, 37.7% in the distal segment, 7.5% in the middle segment, 5.7% proximal ureter, and 15.1% had a long segmental stenosis. In 18.9%, the location was not specified. Techniques used included ureterocystostomy (30.2%), ureteroureterostomy (34%), ureteropyelostomy (30.1%), pyeloileostomy (1.9%), and ureteroileostomy (3.8%). No difference in overall graft survival (HR 1.24 95% CI 0.33-4.64, p = 0.7) was detected when compared to the matched control group. Conclusion: Using a variety of techniques designed to re-establish effective urinary flow, we have been able to salvage a high percentage of these allografts. When performed by an experienced team, a ureteric complication does not significantly impact graft survival or function as compared to a matched control group
