Abstract

This paper depicts a model which not only evaluates the node's reputation, but also avoids the malicious node in the forwarding path. The simulation is performed by using the NS2 software. This model uses the IEEE 802.11 protocol with RTS, CTS, DATA and ACK signalling at the MAC layer. The paper models packet forwarding, passive misbehavior, active misbehavior and avoidance of malicious nodes in the route. The model also takes into account the blocking caused by the hidden node problem in wireless networks. The results achieved are both graphical as well as in the form of a network animation. Curves such as throughput and jitter are plotted to analyse the performance of the MANET.

Abstract

Quality Function Deployment (QFD) is a product development process that encompasses a sheer amount of data gathered from customers through several market research techniques like personal interview, focus groups, surveys, video conferencing etc. This massive, unsorted and unstructured data is required to be transformed into a limited number of structured information to represent the actual 'Customer Needs'. However the process is tedious and time consuming and cannot be dealt with manually. In order to address these issues, this paper proposes a futuristic software framework based on an Affinity Process. The paper begins with the topic introduction and outlines the QFD process. The paper then describes the Affinity Process, builds the data structure and then makes an attempt to build the proposed framework using tools Visual Basic (VB) and MS-Access. The proposed framework is developed as a part of QFD software and it is anticipated that when completely developed, it would act as a vital component of QFD software.

Abstract

Mobile ad hoc networks are this newly evolved networking concept primarily due to the increase in use of wireless technology for communication. But the MANET concept faces issues over resource sharing, volatility of the network and erroneous data transmission. Thus a new cross layer design approach is being proposed where service discovery and routing functions are coupled for optimization. Congestion avoidance adopted due to the noise resulting from interference rather than from actual congestion or packet loss results in low bandwidth utilization. The new approach adopted in this paper will try and overcome these issues by sharing the information among various levels and minimizing data retransmissions and losses by making appropriate responses for the events.

Keywords

Abstract

Siddha Clinical Research Unit (SCRU) Tirupati, working under the Central Council for Research in Siddha (CCRS), Ministry of AYUSH, Govt. of India, conducted a National Web conference titled “Integrated Siddha Approach in Clinical Practice and Research on COVID-19 Pandemic (ISACC)” on 23^rd Dec 2020, as a part of the fourth Pre-Siddha Day observance. Totally, 256 participants from Siddha colleges and various institutes of CCRS attended the Web conference and 9 eminent Speakers share their knowledge at the conference. The Technical session was separated by three panels, (i)Siddha Standalone and Integrative Clinical trials on COVID-19, (ii)Siddha Preventive and Prophylactic Measures on COVID-19, (iii)Experiences in Siddha Integrative Clinical Practice on COVID-19. The take home message of the conference insisted upon the three facts - the need for more clinical trials , need for increased experience sharing platforms for Siddha medical system and finally that Siddha standalone as well as integration for COVID-19 management gave significant outcome in both preventive and promotive healthcare. Central Council for Research in Siddha (CCRS), Ministry of AYUSH, Govt. of India and Directorate of Indian Medicine and Homeopathy (DIM&H), Government of Tamil Nadu, contributed a lot in Research and services in COVID-19 pandemic.

Abstract

Respiratory Tract Infections (RTIs) are the most common, and potentially most severe, of infections treated by health care practitioners. Lower RTIs along with influenza, are the most common cause of death by infection. The fatality risk is doubled if the person is with other morbid conditions or in extremes of age. These seasonal respiratory infections caused by viruses are of more concern as their spread is very vast than we imagine. COVID-19 (corona virus disease 2019) is such a pandemic respiratory illness caused by severe acute respiratory syndrome corona virus 2 (SARS-CoV-2), a strain of Corona virus. The emerging anti-microbial resistance and easy spread of respiratory pathogens has also increased the challenge for appropriate management of RTI like COVID-19. Drugs with anti-viral property and potency to prevent the comorbidity stand are the need of the hour. This review article includes information on preclinical studies and clinical studies to add a scientific validation to formulations that are commonly used in Siddha system of Medicine. The ingredients of the Siddha drugs possessing anti-viral property and immune-modulatory effect particularly against respiratory pathogens are elaborated. Evidence of anti-viral property has been made out to the light for further clinical trials.
