Performance Evaluation of Caching Policies in NDN - an ICN Architecture

Information Centric Networking (ICN) advocates the philosophy of accessing the content independent of its location. Owing to this location independence in ICN, the routers en-route can be enabled to cache the content to serve the future requests for the same content locally. Several ICN architectures have been proposed in the literature along with various caching algorithms for caching and cache replacement at the routers en-route. The aim of this paper is to critically evaluate various caching policies using Named Data Networking (NDN), an ICN architecture proposed in literature. We have presented the performance comparison of different caching policies naming First In First Out (FIFO), Least Recently Used (LRU), and Universal Caching (UC) in two network models; Watts-Strogatz (WS) model (suitable for dense short link networks such as sensor networks) and Sprint topology (better suited for large Internet Service Provider (ISP) networks) using ndnSIM, an ns3 based discrete event simulator for NDN architecture. Our results indicate that UC outperforms other caching policies such as LRU and FIFO and makes UC a better alternative for both sensor networks and ISP networks

Effect of Drip Irrigation and Polythene Mulch on the Fruit Yield and Quality Parameters of Mango (Mangifera indica L.)

A field experiment was carried out at Horticultural Research Farm, Precision Farming Development Centre, Department of Horticulture, Indira Gandhi Krishi Vishwavidyalaya, Raipur, Chhattisgarh during the year 2009- 2010 in Randomized Block Design with three replications and ten treatment combinations ( 100%, 80%, 60%, and 40% water through drip irrigation system with and without polythene mulch + Basin irrigation with and without mulch). Fruits characters, yield and yield attributing parameter were higher under drip irrigation with 0.6 V volume of water + polythene mulch (T8) and the same characters were lowest under control (Basin irrigation with V- volume of water). Application of black plastic mulch with drip irrigation system can conserve moisture, check the growth of weeds and improve the fruit yield and quality. Water use efficiency was higher under drip irrigation with 0.6 V volume of water + polythene mulch and low under basin irrigation with V volume of water. The net income and benefit cost ratio was also higher under the treatment T8 as compared to surface method of irrigation

Effect of mobile reminders on screening yield during opportunistic screening for type 2 diabetes mellitus in a primary health care setting: A randomized trial

AbstractObjective. We wanted to study whether mobile reminders increased follow-up for definitive tests resulting in higher screening yield during opportunistic screening for diabetes. Methods. This was a facility-based parallel randomized controlled trial during routine outpatient department hours in a primary health care setting in Puducherry, India (2014). We offered random blood glucose testing to non-pregnant non-diabetes adults with age >30years (667 total, 390 consented); eligible outpatients (random blood glucose ≥6.1mmol/l, n=268) were requested to follow-up for definitive tests (fasting and postprandial blood glucose). Eligible outpatients either received (intervention arm, n=133) or did not receive mobile reminder (control arm, n=135) to follow-up for definitive tests. We measured capillary blood glucose using a glucometer to make epidemiological diagnosis of diabetes. The trial was registered with Clinical Trial Registry of India (CTRI/2014/10/005138). Results. 85.7% of outpatients in intervention arm returned for definitive test when compared to 53.3% in control arm [Relative Risk=1.61, (0.95 Confidence Interval — 1.35, 1.91)]. Screening yield in intervention and control arm was 18.6% and 10.2% respectively. Etiologic fraction was 45.2% and number needed to screen was 11.9. Conclusion. In countries like India, which is emerging as the diabetes capital of the world, considering the wide prevalent use of mobile phones, and real life resource limited settings in which this study was carried out, mobile reminders during opportunistic screening in primary health care setting improve screening yield of diabetes

Fashioning readers: canon, criticism and pedagogy in the emergence of modern Oriya literature

Through a brief history of a widely published canon debate in nineteenth century Orissa, this article describes how anxieties about the quality of ‘traditional’ Oriya literature served as a site for imagining a cohesive Oriya public who would become the consumers and beneficiaries of a new, modernized Oriya-language canon. A public controversy about the status of Oriya literature was initiated in the 1890s with the publication of a serialized critique of the works of Upendra Bhanja, a very popular pre-colonial Oriya poet. The critic argued that Bhanja’s writing was not true poetry, that it did not speak to the contemporary era, and that it featured embarrassingly detailed discussions of obscene material. By unpacking the terms of this criticism and Oriya responses to it, I reveal how at the heart of these discussions were concerns about community building that presupposed a new kind of readership of literature in the Oriya language. Ultimately, this article offers a longer, regional history to the emerging concern of post-colonial scholarship with relationships between publication histories, readerships, and broader ideas of community – local, Indian, and global
