How Smart is your Android Smartphone?

Smart phones are ubiquitous today. These phones generally have access to sensitive personal information and, consequently, they are a prime target for attackers. A virus or worm that spreads over the network to cell phone users could be particularly damaging. Due to a rising demand for secure mobile phones, manufacturers have increased their emphasis on mobile security. In this project, we address some security issues relevant to the current Android smartphone framework. Specifically, we demonstrate an exploit that targets the Android telephony service. In addition, as a defense against the loss of personal information, we provide a means to encrypt data stored on the external media card. While smartphones remain vulnerable to a variety of security threats, this encryption provides an additional level of security

Dynamic Hierarchical Cache Management for Cloud RAN and Multi- Access Edge Computing in 5G Networks

Cloud Radio Access Networks (CRAN) and Multi-Access Edge Computing (MEC) are two of the many emerging technologies that are proposed for 5G mobile networks. CRAN provides scalability, flexibility, and better resource utilization to support the dramatic increase of Internet of Things (IoT) and mobile devices. MEC aims to provide low latency, high bandwidth and real- time access to radio networks. Cloud architecture is built on top of traditional Radio Access Networks (RAN) to bring the idea of CRAN and in MEC, cloud computing services are brought near users to improve the user’s experiences. A cache is added in both CRAN and MEC architectures to speed up the mobile network services. This research focuses on cache management of CRAN and MEC because there is a necessity to manage and utilize this limited cache resource efficiently. First, a new cache management algorithm, H-EXD-AHP (Hierarchical Exponential Decay and Analytical Hierarchy Process), is proposed to improve the existing EXD-AHP algorithm. Next, this paper designs three dynamic cache management algorithms and they are implemented on the proposed algorithm: H-EXD-AHP and an existing algorithm: H-PBPS (Hierarchical Probability Based Popularity Scoring). In these proposed designs, cache sizes of the different Service Level Agreement (SLA) users are adjusted dynamically to meet the guaranteed cache hit rate set for their corresponding SLA users. The minimum guarantee of cache hit rate is for our setting. Net neutrality, prioritized treatment will be in common practice. Finally, performance evaluation results show that these designs achieve the guaranteed cache hit rate for differentiated users according to their SLA

Challenges and Opportunities for Trade and Financial Integration in Asia and the Pacific

During the past two decades, intraregional trade has assumed a lot of importance - with intraregional trade growing rapidly in several regions, such as the Association of Southeast Asian Nations (ASEAN), North American Free Trade Agreement (NAFTA) and the European Union. However, intraregional trade in South Asia has not witnessed rapid expansion despite the institutional measures taken by the South Asian countries through the South Asian Preferential Trade Agreement (SAPTA) and the South Asian Free Trade Agreement (SAFTA).intraregional trade, South Asia, ASEAN, NAFTA, SAFTA, SAPTA

Radial modes of levitating atmospheres around Eddington-luminosity neutron stars

We consider an optically thin radiation-supported levitating atmosphere suspended well above the stellar surface, as discussed recently in the Schwarzschild metric for a star of luminosity close to the Eddington value. Assuming the atmosphere to be geometrically thin and polytropic, we investigate the eigenmodes and calculate the frequencies of the oscillations of the atmosphere in Newtonian formalism. The ratio of the two lowest eigenfrequencies is $\sqrt{\gamma+1}$, i.e., it only depends on the adiabatic index.Comment: 7 pages, 3 figures, Accepted for publication in MNRA

An Analysis of the Special Safeguard Mechanisms in the Doha Round of Negotiations - A Proposed Price-trigger-based Safeguard Mechanism

In the Doha Round of negotiations on agriculture it has been decided that all developing and least developed Member countries of the WTO will have access to a Special Safeguard Mechanism (SSM). This means that developing countries will now have the option to temporarily impose higher tariff rates on the import of an agricultural product if there is either a surge in its import volumes or a sharp dip in its import prices. However, the exact mechanisms of the implementation of SSMs have not been spelt out. It is also not clear what legal provisions the Member countries will have to follow to use this safeguard mechanism. This paper takes a detailed look at the SSM and analyzes its usefulness for developing countries. It also explores how the concept of a special agricultural safeguard has evolved in the present round of negotiations and what are the country positions on SSMs in the Doha Round. The paper then proposes a price-trigger-based SSM instrument which is consistent with the goals spelt out in the Doha Development Agenda and satisfies most of the desired features of a safeguard instrument.WTO, agriculture, Volatility, Special safeguards, Tariff rates

Enrichment on quality of aonla (Emblica officinalis G.) fruit bars by blending

The main objective of the study was to standardize enrichment of aonla pulp to develop fruit bars. The experiment was laid out in Completely Randomized Design (CRD) with 10 treatments. Aonla pulp was blended with 25 to 75% of different fruit (mango, papaya and jackfruit) pulp viz. Aonla pulp, Aonla with mango, papaya and jackfruit in different proportion of 3:1, 1:1 and 1:3 each fruit respectively. The initial moisture content was higher in aonlapulp enriched with mango pulp in 1:3 proportions. Enrichment of aonlapulp with fruit pulp of mango, papaya and jackfruit reduced the ascorbic acid, titratable acidity and tannin content of the resultant fruit bars compared to that from pure aonla pulp, which is an indication in the reduction of astringency. Enrichment also resulted in an increase in total soluble solids, reducing, non-reducing and total sugars of the resultant fruit bars. Enrichment of aonla pulp with fruit pulp of provitamin A rich fruits like mango, papaya and jackfruit showed a rise in total carote-noids and reduced astringency and acidity, thereby resulting in fruit bars with altered palatability and enhanced nutrition. Enriched fruit bars contained three vital antioxidants viz. Vitamin C, carotenoids and polyphenols of all the treatments, enriched fruit bar containing 25 % aonlaand 75 % mango (T4) was found superior in organoleptic evaluation

Morphological and germination physiognomies of Carissa carandas seedlings influenced by seed storage at ambient conditions

The present study was taken up to know the morphological and germination physiognomies of karonda (Carissa carandas) seeds influenced by seed storage period at ambient conditions (26 ?C temperature and 55 % RH). Seeds were subjected to store at 10, 20, 30, 40, 50 and 60 days at room temperature (26?C). Germination percentage and various morphological characteristics viz., vigour index, fresh weight of shoot and root, dry weight of shoot and root, root to shoot ratio were recorded. Among stored seeds 10 days old seeds recorded highest germina-tion percentage (57 %) and 60 days old seeds recorded lowest germination (20.33 %). At the end (90 days after sowing) 10 days old seeds again possessed higher fresh weight of root (0.300 g) and shoot (1.240 g), dry weight of root (0.103 g) and shoot (0.487 g), root to shoot ratio (0.212) and vigour index (1772.70 cm) among stored seeds. These physiological observations were quite similar with the freshly harvested seed which found maximum values for all the parameters owing to higher moisture content. Karonda seeds showed good viability upto10 days thereafter its value declined and it reached minimum after 60 days of storage

Energy Controlled Edge Formation for Graphene Nano Ribbons

On the basis of first principles calculations, we report energy estimated to cut a graphene sheet into nanoribbons of armchair and zigzag configurations. Our calculations show that the energy required to cut a graphene sheet into zigzag configuration is higher than that of armchair configuration by an order of 0.174 eV. Thus, a control over the threshold energy might be helpful in designing an experiment for cutting a graphene sheet into smooth edged armchair or zigzag configurations
