thesisCurrent Intrusion Detection Systems (IDS) in a typical enterprise or campus network are limited by having a number of static monitoring points and static IDS resources deployed. The monitoring points are typically deployed using hardware optical taps or span ports which are directly fed into the IDS. The IDS system is a compute resource requiring dedicated-server-grade hardware, and these are statically configured when installing the network for an enterprise or campus. We designed a framework for making a distributed elastic Intrusion Detection System (IDS) for a Software Defined Network (SDN) capable network, called Distributed Elastic Intrusion DeTECTion (DEIDtect). We combine the flexibility of SDN and the elastic resource usage of a cloud infrastructure with a DEIDtect orchestrating controller to achieve an elastic IDS framework. DEIDtect enables simple and more dynamic management of IDS systems. The flexibility of our approach also enables new IDS use cases and deployment strategies

Intelligent transportation system and smart traffic flow with IOT

64-67There has been an increase in vehicles across the globe. Also, the congestion due to traffic has leapfrogged in India. The traffic flow information has been required to find out the route with minimum congestion and forecast the traffic. And this has been a part of the Intelligent Transportation System (ITS) which would help build smart cities. A lot of work has been done on the traffic measurement system. But the integration of emerging techniques such as the Internet of Things (IoT) and cloud computing has provided a lot of research scope in ITS. This paper has proposed an IoT-based method to determine the real-time traffic flow in a road section with ultrasonic sensors, Arduino, ESP8266 Wi-Fi module, and an open-source cloud. There has been an average traffic flow every five minutes to be displayed in the cloud platform. This method can be very much cost-effective with less power consumption and improved accuracy. Hence, the proposed IoT-based technique has provided the traffic flow data, and this data shall further be used for traffic predictions using machine learning algorithms

CBSE-2014 [2 nd and 3 rd April 2014] Challenges in Biochemical Engineering and Biotechnology for Sustainable Environment Comparative Study on Candida Sp. for the Production of Glycerol

Abstract : Candidmagnoliae and Candida glycerinogenes are the yeast isolated from the natural environment used for the production of glycerol. In this work potential of glycerol production by both candida species was compared by the fermentation of glucose by optimizing certain parameters.C.glycerimogenesconverts up to 64.5% (w/w) of the available glucose into glycerol and it was 55% in C. magnolia. C. glycerinogenesyields 9% of higher concentration of glycerol than C. magnoliae. In C. magnoliaethe optimum temperature of 30 o C and a pH of 5 yields highest glycerol production whereas for C.glycerinogenesa temperature of 32 o C and a pH of 5. The parameters which found to influence the glycerol production like phosphate ,glucose were studied

Comparative study to evaluate the efficacy of radiofrequency ablation versus trichloroacetic acid in the treatment of xanthelasma palpebrarum

Background: Xanthelasma palpebrarum (XP) is a metabolic disorder involving the eyelids. Radiofrequency(RF) surgery and trichloroacetic acid (TCA) applications have been listed among the procedures for XP, but comparative studies are not available. Aim: To compare the efficacy of radiofrequency surgery versus trichloroacetic acid application in the treatment of XP. Settings and Design: 20 consecutive cases of XP attending dermatology, medicine and endocrinology out-patient departments of M.S.Ramaiah teaching hospital were enrolled for the study. It was an open-label clinical trial conducted in our hospital for a duration of 1 year. Materials and Methods: 20 consecutive patients conforming to inclusion criteria were selected for the study. For each patient, lesions were treated with radiofrequency ablation on one side and TCA application on the other side. Results: RF ablation was done for 12 patients over right eye lesions and 8 patients over the left eye lesions. TCA applications were done for 8 patients over right eye lesions and 12 patients over left eye lesions. 70% of lesions treated with RF ablation had a score of improvement of 4 and 70% of lesions treated with TCA application had a score of improvement of 4, at 4 weeks of follow-up. At four weeks of follow-up 40% in RF group and 15% in TCA group had scarring and 45% in RF group and 30% in TCA group had pigmentation. Conclusion: RF ablation as compared to TCA application, required fewer sessions for achieving more than 75% clearance of lesions. However, TCA applications were associated with fewer complications comparatively

Recurrence of tuberculosis among newly diagnosed sputum positive pulmonary tuberculosis patients treated under the Revised National Tuberculosis Control Programme, India: A multi-centric prospective study

<div><p>Introduction</p><p>There is lack of information on the proportion of new smear—positive pulmonary tuberculosis (PTB) patients treated with a 6-month thrice-weekly regimen under Revised National Tuberculosis Control Programme (RNTCP) who develop recurrent TB after successful treatment outcome.</p><p>Objective</p><p>To estimate TB recurrence among newly diagnosed PTB patients who have successfully completed treatment and to document endogenous reactivation or re-infection. Risk factors for unfavourable outcomes to treatment and TB recurrence were determined.</p><p>Methodology</p><p>Adult (aged ≥ 18 yrs) new smear positive PTB patients initiated on treatment under RNTCP were enrolled from sites in Tamil Nadu, Karnataka, Delhi, Maharashtra, Madhya Pradesh and Kerala. Those declared “treatment success” at the end of treatment were followed up with 2 sputum examinations each at 3, 6 and 12 months after treatment completion. MIRU-VNTR genotyping was done to identify endogenous re-activation or exogenous re-infection at TB recurrence. TB recurrence was expressed as rate per 100 person-years (with 95% confidence interval [95%CI]). Regression models were used to identify the risk factors for unfavourable response to treatment and TB recurrence.</p><p>Results</p><p>Of the1577 new smear positive PTB patients enrolled, 1565 were analysed. The overall cure rate was 77% (1207/1565) and treatment success was 77% (1210 /1565). The cure rate varied from 65% to 86%. There were 158 of 1210 patients who had TB recurrence after treatment success. The pooled TB recurrence estimate was 10.9% [95%CI: 0.2–21.6] and TB recurrence rate per 100 person–years was 12.7 [95% CI: 0.4–25]. TB recurrence per 100 person–years varied from 5.4 to 30.5. Endogenous reactivation was observed in 56 (93%) of 60 patients for whom genotyping was done. Male gender was associated with TB recurrence.</p><p>Conclusion</p><p>A substantial proportion of new smear positive PTB patients successfully treated with 6 –month thrice-weekly regimen have TB recurrence under program settings.</p></div
