Secure Sharing Of Related Organization Recordsin Cloud Computing

Cloud computing has emerged as one of the most influential paradigms in the IT industry in recent years. Since this new computing technology requires users to entrust their valuable data to cloud providers, there have been increasing security and privacy concerns on outsourced data. Several schemes employing attribute-based encryption (ABE) have been proposed for access control of outsourced data in cloud computing. The proposed scheme is not only achieves scalability due to its hierarchical structure, also inherits flexibility and fine-grained access control in supporting compound attributes of ASBE. This method is used to access the single dataset or local dataset from the cloud computer. In proposed system, data interoperation systems integrate information from different local sources to enable communication and exchange of data between them. A common model for these systems involves a global representation of the local data, which acts as a mediator for translating queries and conveying data to and from these sources using the global-as view approach. In addition, global resource employs multiple value assignments for access expiration time to deal with user revocation more efficiently than existing schemes. It formally proves the security of global resource based on security of the ciphertextpolicy attribute-based encryption (CP-ABE) scheme and analyzes its performance and computational complexity.
The effect of MFC on the pressability and paper properties of TMP and GCC based sheets

Abstract Different qualities of microfibrillated cellulose (MFC) were blended with thermomechanical pulp (TMP) and ground calcium carbonate (GCC) filler. The addition of MFC reduced the drainage of the pulp suspension but improved strength properties. Wet pressing experiments showed that optimal use of MFC and filler could enhance the strength and optical properties without reducing the solids content after wet pressing. Field-emission scanning electron microscopy (FESEM) revealed that MFC adsorbed onto and contributed to the bonding of the filler particles and fibres. The MFC binds the filler-MFC-fines aggregates to the fibre network and partially filled the pore network. As a result, MFC addition increased the air resistance and internal bonding of the sheet.
Architecture of low power energy harvester using hybrid input of solar and thermal for laptop or notebook: A review

This paper aims to develop and design the architecture of Low Power Hybrid Energy Harvester (LPHEH) using the hybrid input of solar and thermal that can be harvested for self-powered laptop or notebook. This research will focus on the development of the high performance boost power converter to power up any laptop or notebook and design power management system of the hybrid input of solar and waste heat that has been released. The main function of the boost converter is to generate a sufficient DC power supply for laptop or notebook. The second stage focuses on investigation, design and development of the architecture to convert the solar and waste heat energy to reusable energy. The solar energy harvesting elements such as solar panels and energy storage components are used and to be matched to each other with sufficient energy required to increase the energy harvesting efficiency. The proposed design performances will be described using PSPICE software simulation and experimental results. The final stage is to integrate the first stage and second stage, power management module and charge controller module. Then, the developed LPHEH will be simulated, synthesis using Mentor Graphics and coding using Verilog and then download the LPHEH modules into FPGA board for real time verification. The layout architecture of LPHEH will be tested and analyzed using CALIBRE tools from Mentor Graphics. The expected result from this LPHEH is to get 12 V to 20 V of the regulated output voltage from minimum input voltage sources range from 5 V to 12 V with efficiency more than 90%.
Boron and nitrogen doping of graphene from first principles

The modification of the electronic properties of sp carbon nanostructures by the controlled addition of foreign atoms into the carbon lattice has been widely proposed and investigated [1,2], in close analogy to the doping of silicon in the semiconductors industry. However, in contrast with conventional materials, the effect of foreign atoms in nanostructures is expected to depend significantly on the position and surrounding of each atom due to the quantum confinement of the electrons [2]. In principle, the fact that nitrogen atoms contain one additional electron than carbon, suggests that nitrogen doped carbon nanostructures will exhibit the characteristics of an n-type material [3,4]. Similarly, boron atoms which lack of one electron with respect to carbon atoms are good elements to achieve a p-doped material [2]. Furthermore, recent experiments on graphene reveal through scanning tunneling microscopy (STM) images, that B and N doping can occur in different kinds of geometries [5,6].
Empirical analysis of fiscal dominance and the conduct of monetary policy in Nigeria

The study empirically investigates fiscal dominance and the conduct of monetary policy in Nigeria, using quarterly data from 1986Q1 to 2016Q4. It adopts the vector error correction mechanism (VECM) and cointegration technique to analyze the data and make inference. The findings reveal that there is no evidence of fiscal dominance in Nigeria. The empirical results show that budget deficit, domestic debt and money supply have no significant influence on the average price level. However, budget deficit and domestic debt are shown to have significant influence on money supply, but only in the short-run. The policy implication is that the government should enforce fiscal discipline through the appropriate institution and the Central Bank should be given autonomy to perform the primary function of long-term price stability, among other functions.
Measuring the Information Security Maturity of Enterprises under Uncertainty Using Fuzzy AHP

Generally, measuring the Information Security maturity(ISM) is the first step to build a new knowledge information security management system in an organization. Knowing the ISM level helps organizations decide the type of protection strategies and policies will be taken and their priorities to strengthen their competitive ability. One of the possible ways to solve the problem is a using multiple criteria decision-making (MCDM) methodology. Analytic hierarchy process (AHP) is one of the most commonly used MCDM methods, which combines subjective and personal preferences in the information security assessment process. However, the AHP involves human subjectivity, which introduces vagueness type of uncertainty and requires the use of decision-making under those uncertainties. In this paper, the IS maturity is based on hierarchical multilevel information security gap analysis model for ISO 27001:2013 security standard. The concept of fuzzy set is applied to Analytic Hierarchical Process (AHP) to propose a model for measuring organizations IS maturity under uncertain environment. Using fuzzy AHP approach helps determine more efficiently importance weights of factors and indicators, especially deal with imprecise and uncertain expert comparison judgments. A case study is used to illustrate the better new method for IS evaluation.
The Role of Saponin as Feed Additive for Sustainable Poultry Production

Poultry, especially broiler is an important protein source for people in developing countries. Under intensive condition, economical and efficient broiler production is disturbed by disease attack due to poor biosecurity management. Feed additives (coccidiostat and antibiotic growth promoter/AGP) that added to feed for disease prevention and growth improvement, have been banned by many countries including Indonesia. Antibiotic growth promoter can be substituted by bioactive compounds in certain plants which can improve poultry production. One of bioactive compounds is saponin which is a glycoside. This paper provides information about source and function of saponin as feed additive for poultry production. Saponin extracts or saponin containing plants have several functions, such as anticoccidia, immunostimulant, antibacteria and antifungi. Sustainable poultry production requires continues supply of feed ingredients and additive with consistent in quality. High saponin-containing plants need to be planted widely and supported by stakeholders for their avability and sustainability.
Comparison of Pre-emptive Use of Diclofenac, Ketorolac and Tramadol for Post-operative Pain in Laparoscopic Cholecystectomy

Under treatment of postoperative pain has been the topic of several recent editorials. The prevention, recognition, and management of postoperative pain in adults, as well as in children, have been receiving a great deal of interest. The poor outcome obtained with current regimens is primarily due to the inadequacies of drug administration techniques rather than the qualities of opioids themselves. In this prospective study comparison of preemptive use of diclofenac, ketorolac and tramadol was done for postoperative pain in laparoscopic cholecystectomy. 60 patients were divided into three groups. Group A received injection Diclofenac (3mg/kg) 75mg maximum at a time. Group B received injection Ketorolac (30 mg). And group C patients received injection Tramadol (100 mg). All drugs were given intravenous half an hour before induction. Analgesic efficacy was measured in VAS scale. In addition pulse, systolic blood pressure, diastolic blood pressure, mean blood pressure, total pethidine requirement and time of first pethidine requirement were recorded Patients received an increment of 10-20 mg of pethidine when pain score was 3-4. In this study, total pethidine consumption in group A is 56.5±5.14, in group B is 46.75±4.65 and in group C is 49±5.42. It shows that group B and group C have same analgesic effectiveness and which is better than group A. On the basis of present prospective clinical study postoperative pain can be managed by preemptive use of diclofenac, ketorolac and tramadol. The analgesic efficacy of ketorolac and tramadol is same and better than diclofenac. Key Words: Pre-emptive analgesia, Laparoscopic cholecystectomy.

Above- and below-ground response to soil moisture change on an alpine wetland ecosystem in the Qinghai-Tibetan Plateau, China

Abstract. Climate change is expected to affect plant communities worldwide. However, less is known about the consequences of global warming-induced decrease of soil moisture on alpine wetland ecosystem in the Qinghai-Tibetan Plateau. To determine response of natural alpine wetland community to decrease of soil moisture, we did a gradient analysis of soil moisture by sequence space-series variation. We used sequence space-series variation of soil moisture to reflect potential time-series variation of soil moisture in alpine wetland community, by examining the effects of spatial heterogeneity of soil moisture on wetland community, as well as by determining how shifts in above- and below-ground properties of alpine wetland community. We found that vegetation aboveground biomass, cover and height all significantly increased with increase of soil moisture, but species richness was decreased. Soil organic carbon, total nitrogen, available nitrogen, total phosphorus and available phosphorus all significantly increased with increase of soil moisture, but soil pH value, total potassium and available potassium were significantly decreased. Meanwhile, species richness showed significantly positive correlations to aboveground biomass, covers and height. Aboveground biomass, vegetation covers and height were all significant positively related to soil organic carbon, total N, P, and available N, P, but negatively related to total K. But, species richness were significant negatively related to soil organic carbon, total N, P, and available N, P, but positively related to total K. Our observation indicates that decreasing of soil moisture may potentially negatively impact on the above- and below-ground properties in alpine wetland community.
Modeling the Relationship between FDI and Financial Development in Small Island Economies: A PVAR Approach

FDI is considered as an important source of capital investment for small island economies and is considered as a crucial tool for attaining economic growth and development. Most studies that have been done relating to foreign direct investment (FDI) are rather on the link between FDI and economic growth or even the link between FD and economic growth. Certainly, there is sufficient theoretical rationale to ascertain that FDI does influence the development of financial market of the recipient countries. Hence, basing on the argument that there is a lack of studies done in this area mainly for the case of small island economies, this paper uses a panel vector autoregressive model (PVAR) which caters for both endogeneity and dynamism, and investigates the relationship between FDI and FD over the time period spanning from 1990 to 2013. Actually, the study shows that FDI can be an important ingredient for developing the financial market in small island economies. For instance, a bi-causal relationship between FDI and FD is observed from the results. Also, economic growth has been identified to play a crucial role in boosting financial development in this study. Moreover other interesting relationships have been detected in the PVAR model.
Approach to Topographic Map, Hydrogeological and Environmental Isotopes Analysis to Delineation of Watersheds in Drought-prone Areas

Gunung Kidul regency is one of the regencies in Indonesia that almost every year (often) is susceptible to drought, there is an even in term of synonymous with a drought in the province. Water is the essential lifeblood on Earth, with the power to generate, sustain, receive, and ultimately to unify life. Water is also one of the most important resources that need to be protected, conserved, and maintained to support humanity and all life on earth. Drought is a state of shortage of water supply in an area in which a prolonged period (several months to years). Usually, these events appear if a region is continuously subjected to rainfall below the average. Dry season long will cause drought. Drought is also a lack of water for human life and other living things in an area that is usually not a lack of water.The environmental isotopes most widely used as a tracer in the study of hydrology cycle are the stable isotopes deuterium (2H), oxygen-18 (18O) and carbon-13 and the radioisotopes tritium (3H) and carbon-14 (14C). The use of environmental isotopes as a tracer in groundwater studies are usually complementary to approach topography, hydro geology, and geology which has been frequently used.The result of this research show that elevation as an orthometric height of the 15 wells water in the research has a variation elevation which spread at most of the district in The from -18.390 m at Girisubo district up to 238.599 at Nglipar district m. Concerning with elevation of the water table at several geological cross section (East - West) are close to orthometric height.
Relationship between energy consumption and economic growth in South Africa: Evidence from the bootstrap rolling-window approach

ABSTRACT This article examines the relationship between energy consumption (EC) and economic growth for South Africa for the period 1971–2009. Most studies examining this relationship do assume that it remains constant through the years; however, the reality might be different since many factors can affect the existence and direction of this causality. This article looks at a bivariate vector autoregressive process and takes into consideration any instability in the model using bootstrap rolling Granger non-causality tests. Full-sample Granger causality tests report no causal relationship between the two variables. Moreover, parameter stability tests detect instability in the model which means that the full-sample Granger causality results are not valid. We therefore allow for the possibility of structural breaks by using bootstrap rolling-window Granger causality tests. Although our results are not very strong, we do however find a sub-period from 1987 to 1989 where EC has a causal effect on gross domestic product growth. Except for this brief sub-period, the results show no linkage between economic growth and EC.
Valuation of a Basket Loan Credit Default Swap

This paper provides a methodology for valuing a basket Loan CDS (LCDS) by considering both default and prepayment risks. Under “top down” and intensity framework, using a single-factor model, correlated default and prepayment risks are considered, where the stochastic interest rate is used to be their common factor. All stochastic processes in the model are assumed to follow CIR processes. Through Feynman-Kac formula, we obtain a PDE problem and its closed-form solution. Numerical examples are provided.
Indication of antagonistic interaction between climate change and erosion on plant species richness and soil properties in semiarid Mediterranean ecosystems

We analyzed the consequences of climate change and the increase in soil erosion, as well as their interaction on plant and soil properties in semiarid Mediterranean shrublands in Eastern Spain. Current models on drivers of biodiversity change predict an additive or synergistic interaction between drivers that will increase the negative effects of each one. We used a climatic gradient that reproduces the predicted climate changes in temperature and precipitation for the next 40 years of the wettest and coldest end of the gradient; we also compared flat areas with 20° steep hillslopes. We found that plant species richness and plant cover are negatively affected by climate change and soil erosion, which in turn negatively affects soil resistance to erosion, nutrient content and water holding capacity. We also found that plant species diversity correlates weakly with plant cover but strongly with soil properties related to fertility, water holding capacity and resistance to erosion. Conversely, these soil properties correlate weaker with plant species cover. The joint effect of climate change and soil erosion on plant species richness and soil characteristics is antagonistic. That is, the absolute magnitude of change is smaller than the sum of both effects. However, there is no interaction between climate change and soil erosion on plant cover and their effects fit the additive model. The differences in the interaction model between plant cover and species richness supports the view that several soil properties are more linked to the effect that particular plant species have on soil processes than to the quantity and quality of the plant cover and biomass they support. Our findings suggest that plant species richness is a better indicator than plant cover of ecosystems services related with soil development and protection to erosion in semiarid Mediterranean climates.
Suffering in Igbo-African Ontology

Suffering in a broad sense, is an individual's basic affective experience of unpleasantness and aversion associated with harm or threat of harm. Suffering may be physical or mental. It occurs in the lives of sentient beings in numerous manners, and often dramatically. As a result, many fields of human activity are concerned, from their own points of view, with the meaning of suffering. Considerations include the nature of suffering, its processes, its origin and causes, its meaning and significance, its related personal, social, and cultural behaviours, its remedies, management, and uses. This paper studies the contribution of the Igbo-African world to the ongoing discourse on human suffering. “Igbo” is a language and the name of an ethnic group or tribe in Nigeria. It is referred to as Igbo-African because it is an ethnic group in Africa and relates culturally to other ethnic groups in Africa. This would involve the study of the different Igbo-African perspectives regarding human suffering in the world. This will include the Igbo Cosmological optimistic view which believes that man is the cause of his suffering and not God. The personal god and destiny view which sees human suffering as the product of a person’s personal god. There is also a middle course view, which sees human suffering as the product of both views already expressed. This paper discovers that with all these understandings of evil and its dimensions, evil still remains a puzzle to the Igbo-African. Keywords: Suffering, African, Igbo, Ontology, god, destiny, Nigeria, World, middle-course, experience.
Convergence in Banking Efficiency across European Countries

Since the preparation of the Single Market program in the 80s, financial integration in Europe has been expected to provide gains in growth by favoring competition and efficiency on financial markets. Our paper aims to check whether financial integration has taken place on the banking markets, by investigating the convergence in banking efficiency for European Union countries. We measure cost efficiency of banks from 10 EU countries between 1994 and 2005 with the stochastic frontier approach. Our work then constitutes the first one to apply tests of β and σ convergence specified for panel data on banking efficiency measures. We provide evidence of cross-country differences in cost efficiency and of an improvement in cost efficiency for all EU countries. Tests of convergence support the view of a process in convergence in cost efficiency between EU countries. Robustness checks with alternative specifications confirm these findings. These results support the view that financial integration has taken place on the EU banking markets in the recent years.
Analysis of QoS Platform Cooperation Strategies

In this paper we present a value-oriented modeling approach fort he assessment of the QoS interconnected market. This approach is based on the economics of two-sided markets and takes cross-side market externalities between networks into account. The presented model comes along with a realistic number of players and a higher level of complexity, we are proposing the use of a bottom-up, agent-based model. The novel micro-level modelling approach enables the analysis of QoS interconnection strategies. This model can be used to analyze macro-level simulation results and derive implications for the network type specific optimal interconnection stratagies.
‘Security from Below’ in Contexts of Chronic Violence

At the same time that the field of security moves away from traditional state-centred perspectives towards a human-centred understanding of security, contemporary states seem to be incapable of protecting people from increasingly complex forms of insecurity. Inadequate and inefficient public responses have contributed to the erosion of the idea of security as a public good, especially in contexts of chronic violence. In this article, we suggest that in these contexts ‘security from below’ could help analytically and in practice to humanise security provision by focusing attention on the lived experiences of insecurity, by encouraging participation in debates about the local and universal values that should inform state responses and by enabling people to demand a people-centred but publicly delivered form of security. Rethinking security from below is not a suggestion for replacing the state; it is instead an attempt to increase the capacity of communities and local level actors to articulate their demands for better security provision based on agreed norms and under democratic principles in which security must be at the heart of all struggles for equitable development and social justice.Article first published March 2009, IDSB40.2.
