A practical and convenient method for the synthesis of oxabicyclo[3.3.1]nonenes has been developed using InCl3 (20 mol%) under mild conditions from aldehydes and R-(+)-limonene. Corresponding oxabicyclic compounds were obtained in high yields via (3,5)-oxonium-ene reaction. This protocol tolerates a wide range of substituents and functional groups. Mild reaction conditions, shorter time, and convenient workup makes this methodology practical. 2016 Copyright © Taylor & Francis Group, LLC

This paper focuses on Probabilistic Complex Event Processing (PCEP) in the context of real world event sources of data streams. PCEP executes complex event pattern queries on the continuously streaming probabilistic data with uncertainty. The methodology consists of two phases: Efficient Generic Event Filtering (EGEF) and probabilistic event sequence prediction paradigm. In the first phase, a Non-deterministic Finite Automaton (NFA) based event matching allows to filter the relevant events by discovering the occurrences of the user defined event patterns in a large volume of continuously arriving data streams. In order to, express the complex event patterns in a more efficient form, a Complex Event Processing (CEP) language named as Complex Event Pattern Subscription Language (CEPSL) is developed by extending the existing high level event query languages. Furthermore, query plan-based approach is used to compile the specified event patterns into the NFA automaton and to distribute to a cluster of state machines to improve the scalability. In the second phase, an effective Dynamic Fuzzy Probabilistic Relational Model (DFPRM) is proposed to construct the probability space in the form of event hierarchy. The proposed system deploys a Probabilistic Fuzzy Logic (PFL) based inference engine to derive the composite of event sequence approximately with the reduced probability space. To determine the effectiveness of the proposed approach, a detailed performance analysis is performed using a prototype implementation. © 2016, Zarka Private Univ. All rights reserved.

The IP Multimedia Subsystem (IMS) seems to be the technology that will prevail in Next Generation Networks (NGN s), since the interworking environment and the service flexibility that this technology offers to the currently deployed wireless broadband technologies makes it appealing to users, service developers and network operators. In this paper a heterogeneous network model based on the IMS that integrates the Worldwide Interoperability for Microwave Access (WiMAX), Universal Mobile Telecommunications System (UMTS) and Wireless Local Area Network (WLAN) technologies is proposed and provides it provides guaranteed QoS. The proposed Tight coupled WiMAX-UMTS-WLAN convergence architecture using IMS QoS provisioning algorithm is compared with interworking of WiMAX-UMTS interworking architecture using IMS QoS provisioning algorithm. The QoS performance metrics such as Email upload and download response time, Email traffic received, RIP (routing information protocol) traffic received and sent, TCP delay, TCP retransmission count, Transmission delay, Processing delay and Queuing delay were simulated using Opnet 14.5. © 2013 IEEE.

This paper presents the experimental and Finite Element Analysis results of the RC beams tested and analysed under four-point bending. For FE modeling of RC beams using ANSYS 12.0, IS 456: 2000 codal provisions are used and the critical values of the test and FE Analysis results are compared with the calculated values using the IS code provisions. © 2012 Pillay Engineering College.

This paper presents the findings of the comprehensive experimental investigation on the use of non-prestressed external reinforcing bars at soffit of the RC beams for enhancing the flexural strength. Based on the encouraging results of the preliminary experimental study conducted by the authors, a comprehensive experimental investigation was carried out by testing 20 numbers of RC beams with varying internal and external bar ratio in order to further explore the viability of this technique. External reinforcing bars technique has already been used by keeping the reinforcement at the sides of the beam using deflectors, mechanical anchoring devices and with strengthening end anchorage zones. The reported technique uses external reinforcing bars at the soffit, which eliminates the need of deflectors, and the anchoring was done by adopting a very simple technique, which eliminates the use of mechanical anchoring devices. The proposed technique is found to be cost effective, easy to execute, enhances moment carrying capacity and effective in deflection and crack control. © 2013 RILEM.
