SOCIAL NETWORKING FOR BOTNET COMMAND AND CONTROL

A botnet is a group of compromised computers which is often a large group under the command and control of a malicious user, known as a botmaster. Botnets are generally recognized as a serious Internet threat. Botnets can be used for a wide variety of malicious attacks including spamming, distributed denial of service, and obtaining sensitive information such as authentication credentials or credit card information. This project involves building a botnet centered on Twitter. Our botnet uses individual bots controlled by commands tweeted by botmaster; the botnet can expand in a viral manner by following affected Twitter user’s friends. This botnet is only intended as a proof of concept and it does not perform any malicious actions

Operational radiation safety considerations during superficial x-ray treatment for veterinary applications

2021 Fall.Includes bibliographical references.This study was conducted to determine whether the scatter x-ray emission during a superficial radiation treatment (SRT) using the SRT-100™ result in a significant occupational dose to veterinary personnel present in the room during treatment. Measurements were taken for 50, 70, and 100 kV x-ray for 9 different SRT-100 applicators. The exposure rates at the surface of solid water phantom (SWP) phantom ranged from 3.9 mR/hr for applicator #2 to 396 mR/hr for CB18 for 50 kV, from 41 mR/hr to 2,880 mR/hr for 70 kV, and from 235 mR/hr to 7,500 mR/hr, for 100 kV, respectively. A heat map of scatter x-ray around the x-ray source was generated for 50, 70, and 100 kV at 25 cm and 75 cm above the SWP surface plane. The highest measured exposure rate was at 0.5 m from the applicator and was 76.8 mR/hr at 25 cm above SWP and 33.6 mR/hr at 75 cm above the SWP for 50 kV. Exposure rate values at same locations were 192 mR/hr and 96 mR/hr for 70 kV, and 389 mR/hr and 194 mR/hr for 100 kV, respectively. A horse phantom was utilized to generate a spatial dose profile at 1m for 50, 70, and 100 kV and it was discovered that backscatter emission has an angular response. Residence time for veterinary staff to exceed 10% of quarterly dose limits were calculated for 50, 70, and 100 kV and distances ranging from 0.5m to 2.5 m. These values ranged from a minimum of 24 min for 100 kV at 0.5m to a maximum of 7,813 min for 50 kV at 2.5 m. Minimum distance from the applicator for exposure rates below 2 mR/hr were calculated to be 1.78, 2.52, and 3.45 m, for 50, 70, and 100 kV, respectively

Cultural Transformation, Identity and Resistance in Jhumpa Lahiri’s ‘The Lowland’

Jhumpa lahiri‟s The Lowland is a judicious supplement to her already popular oeuvre of fiction writing, including Pulitzer Prize winner Interpreter of Maladies (1999), The Namesake (2003) and Unaccustomed Earth (2008). The story of novel concerns two siblings, Subhash and Udayan Mitra and due to circumstances in the 1960s, they parted their ways. Subhash moves to United States for higher studies in Oceanography and settles there while his younger brother, Udayan, lives by Marxist ideology. The tumultuous political context in the wake of colonial rule in India marks the personal saga of a family deeper than in any other Lahirian fiction. Lahiri‟s plots are well planned in the backdrop of diasporic predicament of characters striving to cope up with problems of familial relationships and interconnectedness between people. She delves deeply into emotional tangles of her characters and establishes the need for reaching out in renewed emotional communication between them to resolve conflicts and problems of mutual adjustment. Portraying life of the Indian migrants to America, Lahiri has been very poignant in capturing the diasporic spirit of her characters muddled in multiple emotional tangles. However, she deals purely with emotional turmoil and subsequent isolation and guilt experienced by central characters. The narrative deals with the theme of uprooting and assimilation with efforts made to establish connectivity among the characters. The present paper first discusses the concept of identity and cultural transformation in diasporic space and then traces these issues in The Lowland which was shortlisted for Man Booker Prize 2013.Keywords: Identity, Cultural Transformation, Naxalite, Diaspora and Third Space

Bimodal Emotion Classification Using Deep Learning

Multimodal Emotion Recognition is an emerging associative field in the area of Human Computer Interaction and Sentiment Analysis. It extracts information from each modality to predict the emotions accurately. In this research, Bimodal Emotion Recognition framework is developed with the decision-level fusion of Audio and Video modality using RAVDES dataset. Designing such frameworks are computationally expensive and require more time to train the network. Thus, a relatively small dataset has been used for the scope of this research. The conducted research is inspired by the use of neural networks for emotion classification from multimodal data. The developed framework further confirmed the fact that merging modality can enhance the accuracy in classifying emotions. Later, decision-level fusion is further explored with changes in the architecture of the Unimodal networks. The research showed that the Bimodal framework formed with the fusion of unimodal networks having wide layer with more nodes outperformed the framework designed with the fusion of narrow unimodal networks having lesser nodes
