ABSTRACT
In this paper, we have suggested rectifications in differential cryptanalysis of ultra-lightweight block cipher PRESENT reduced to 16 rounds. We have shown that proposed differential attack by Wang [3] on 16 round PRESENT can recover at the most 30 subkey bits, although the author has claimed to recover 32 bits of subkey for last two rounds. We have also computed data complexity and success probability for recovering 30 subkey bits accordingly by the differential attack on 16 round PRESENT.

Post-Reform Development in Asia: Essays for Amiya Kumar Bagchi
No full textThis festschrift volume for professor Amiya Kumar Bagchi dwells on issues often raised in the development debate whether neo-liberal reforms in developing nations have raised inequality and poverty, food insecurity, hindered empowerment of women, aggravated agrarian distress, reallocated resources for private profitability and facilitated the rise of multi-national oligopoly according inferior status to the domestic industries in the host countries most of the issues have been examined on the basis of empirical data drawn from China, India and Bangladesh essays on china concentrate on post-reform issues of inequality across regions and rural-urban locations and its failure to achieve targets of human development while experiencing rapid economic growth discussions on changes in policy environment since the early days of the people\u27s republic of china also constitute the basic themes of the essays food insecurity, growth-poverty-employment relationship, gender discrimination in the labour market and agrarian distress caused by withdrawal of state support to small farmers growing commercial crops and revision of priority sector lending policy at the cost of small farmers and entrepreneurs are the major themes of essays written in the Indian context of post-reform development in an essay on Bangladesh the poverty issues has been revisited in the context of child work agrarian issues have also been raised in an essay where the author proposes an alternative peasant social construction for the dual affirmation of land rights of the state and of the peasant family in the last two essays authors look far beyond the mainstream tradition to develop an analytical framework for understanding issues relating to the recent rise of multi-national firms and the phenomenal growth of India\u27s software technology. -- Provided by publisherhttps://scholarworks.uni.edu/facbook/1150/thumbnail.jp
D-Penicillamine for preventing retinopathy of prematurity in preterm infants
No full textBackground The rate of retinopathy of prematurity (ROP) in moderately premature infants has decreased dramatically with improved care in the neonatal intensive care unit. A low rate of this disorder was unexpectedly observed among infants treated with intravenous D-penicillamine to prevent hyperbilirubinaemia. This observation led to the investigation of its use, both enterally as well as intravenously, to prevent ROP. Objectives To determine the effect of prophylactic administration of D-penicillamine on the incidence of acute ROP or severe ROP and other morbidities in preterm infants. Search methods We used the Cochrane Neonatal Review Group search strategy. Two review authors independently searched multiple electronic databases, previous reviews including cross references, abstracts, conference/symposia proceedings, and expert informants. We updated the search on November 27, 2012. Selection criteria We included randomised or quasi-randomised controlled trials if they administered D-penicillamine and compared it with no treatment or placebo to premature infants and reported on the outcome of ROP. Data collection and analysis We used the criteria and standard methods of the Cochrane Neonatal Review Group to assess the methodological quality of the included trials. One review author examined trials for validity. A second review author checked validity and they reached consensus on the final data before entry into this review. We used the standards of the Neonatal Cochrane Review Group to analyse data. Main results Three randomised trials met the inclusion criteria. The meta-analysis showed no significant differences in the risk of any stage ROP (typical risk ratio (RR) 0.32, 95% confidence interval (CI) 0.03 to 3.70), severe ROP (typical RR 0.38, 95% CI 0.03 to 4.26) or death (typical RR 0.95, 95% CI 0.68 to 1.32) in all treated infants. When the subgroup of infants under 1500 g birth weight was examined, the results were similar. No side effects were reported, and follow-up at one year revealed no significant differences in spasticity or developmental delay. Authors' conclusions Administration of prophylactic D-penicillamine in preterm infants does not prevent acute or severe ROP, death or neurodevelopmental delay. D-penicillamine cannot be recommended for the prevention of ROP based on the available evidence
Exploring the rainfall data from satellites to monitor rainfall induced landslides – A case study
No full textIn the present study, rainfall estimates from TRMM (Tropical Rainfall Measuring Mission) and GPM (Global Precipitation Mission) constellation of satellites are analyzed in the context of rainfall induced landslide occurrences over Western Ghats (WG) of India along with the daily gridded rainfall data developed by the India Meteorological Department (IMD) and Advanced Research Weather Research and Forecasting (ARW) numerical model simulations. This study aims to analyze the pattern of changes in rain rate and total rainfall triggering the large landslides over WG in TMPA (product of TRMM) and IMERG (GPM product) rainfall data sets. As a case study, performance of IMERG V5 is assessed during Malin landslide which occurred on 30 July 2014 (initial GPM era). Results indicate that IMERG shows significant increase in rain rate (>60 mm/h in half-hourly data) during Malin landslide. Near real-time IMERG V5, underestimates the rain rate but increasing pattern of rain-rate are observed which is similar to that of final version. Spatial pattern of ARW rainfall output is also close to the satellite and IMD rainfall patterns. We propose that IMERG V5 can be used as an indicator to reliably depict the higher rainfall scenario over the sites that are vulnerable to rainfall induced landslide occurrence over the WG region.Authors are thankful to the anonymous reviewers for their constructive comments that improved the quality of the article.

A Comparative Study of Manoj Das’s Akasara Isara (Odia) and The Escapist (English)
No full textThere are very few bilingual writers of repute in the country and Manoj Das distinctly stands as a prolific writer who has carved a niche for himself in this arena. In fact, he is one of the greatest writers of the country, who has given a new direction to the bilingual writing and proved his brilliance through his great short stories and novels both in Odia and English languages with his creative genius. He is one of the widely acclaimed bilingual story tellers of the country whose writings have been accepted by the readers for their novelty of thoughts and flawless narration. Many prestigious literary awards like the Sahitya Akademi Award, the Padma Shri and the Saraswati Samman and many more have been bestowed upon him. He is in fact one of the towering literary personalities in the Indian English fictions arena who has been instrumental in establishing a native identity. His in-depth analysis of human emotions and their universal appeal is something that is amazingly brilliant in his writings. He has been widely acclaimed and appreciated for his literary genius and creative brilliance. The present research article attempts a comparative study of these two novels which are unique with their thematic treatment as well as the subtle realities combined with powerful philosophical messages. His novel Akasara Isara (1997) which originally appeared in Odia and later translated by the author himself in English as The Escapist (2001) describes the human tragedy against the backdrop of an all-pervading destiny. The article discusses such issues of translation and bilingual writing. It also focuses on the cultural aspects
Key Author Analysis in Research Professionals’ Relationship Network Using Citation Indices and Centrality
No full textAbstractIn social network analysis, the importance of an actor can be found by using the centrality metrics. There are many centrality metrics available e.g. degree, closeness, betweenness, eigenvector etc. In research community authors forms a social network, which is called Research Professionals’ Collaboration Network. This is similar to social network where each author is an actor and an article written together by some authors establishes collaboration between them. Each author acquires a certain value based on the citation of their articles. There are many citation indices are available such as citation count, h-index, g-index, i10-index etc. To analyze the Research Professionals’ collaboration Network and for finding the key author, the citation indices can be used. In this paper, we compare and combine both social network analysis metrics and the citation indices to get better result in finding the key author
Design of a GSM based digital door lock
No full textThe proposed project is intended to design an access control system using GSM technology. GSM (Global System for Mobile communication) is a digital mobile telephony system that uses a variation of Time Division Multiple Accesses (TDMA) and most widely uses the three digital wireless telephony technologies i.e., TDMA, CDMA & FDMA. The present project is an innovative idea for providing security by restricting the access of certain areas to certain people only. In this case of security, the opening & closing of the gate of the restricted areas is done through SMS. A GSM modem is used for this purpose. It allows only authenticated SIM cards or number for the access purpose rejecting all other unauthenticated SIM card users. When an ‘OPEN ’SMS is sent, the gate opens up and then closes automatically
On the Development of Hybrid Optimization Techniques for Containerized Cloud
No full textContainer-as-a-Service (CaaS) in cloud has emerged as a prominent cloud computing paradigm, providing developers with a convenient platform for deploying and managing containerized applications. In CaaS environments, efficient resource management is crucial for optimizing performance, minimizing costs, and ensuring the timely execution of tasks. Makespan, the total duration required to complete a set of tasks or jobs, is a critical metric for evaluating resource utilization and workload efficiency. This thesis explores on the development of makespan-aware resource management strategies tailored explicitly for containerized cloud. It also talks about the architecture of CaaS model and the basic ideas behind containerization, the advantages of resource isolation, scalability, and portability in CaaS when deploying and managing applications using containers. The main objective of this thesis is to propose different hybrid optimization approaches for minimizing makespan in the containerized cloud while maintaining the required Quality of Service (QoS). Improvements in resource use at the server and virtual machine levels help to achieve the goal. First, a meta-heuristic approach for load balancing in CaaS cloud is proposed to distribute incoming workload across available resources in a balanced manner, minimizing makespan and optimizing resource utilization. Next, a Fractional Pelican Optimization based VM sizing is proposed, which make use of Deep-ConvLSTM to minimize makespan, task rejection rate and response time. Then, a Fractional Pelican Hawks Optimization (FPHO) based container consolidation is proposed to enhance the system performance where energy consumption, resource utilization, SLA violations, and makespan are considered as the performance metric. Simulations show that all three approaches improve the performance of the containerized cloud system. This thesis enhances the state of the art through the following key contributions: A detailed survey of resource management strategy in containerized cloud An approach for load balancing in containerized cloud. An efficient VM sizing technique for hosting containers in cloud. A framework for consolidation of containers in the containerized cloud
