    Financial Option Market Model for Federated Cloud Environments

    Pay-per-use service by Cloud service providers has attracted customers in the recent past and is still evolving. Since the resources being dealt within Clouds are non-storable and the physical resources need to be replaced very often, pricing the service in a way that would return profit on the initial capital...

    Cooperative Spectrum Sensing With Noncoherent Transmission

    The problem of decision fusion for cooperative spectrum sensing in cognitive radio networks is studied when noisy fading channels are present between the Cognitive Radios (CRs) and the Fusion Center (FC). The CRs perform spectrum sensing using energy detection and transmit their binary decisions to the FC for a final...

    MDP-Based Admission Control for Multicast Streaming Services in Wireless Mobile Networks

    The authors investigate the optimal admission control policy for Multicast Streaming Services (MSS) in the 3rd Generation (3G) and beyond wireless mobile networks. An admission decision in MSS is required only when an empty session not being in service is requested due to the point-to multipoint nature, whereas it is...

    Performance Analysis of Cognitive Radio Networks With Channel Assembling and Imperfect Sensing

    This paper investigates the performance of a wideband cognitive radio network where each cognitive user can assemble multiple primary channels. Two channel assembling schemes are considered: a Constant Channel Assembling (CCA) and a Variable Channel Assembling (VCA). In the variable channel assembling scheme, cognitive users assemble their channels on the...

    An Improved Channel Model for Cognitive Radio

    To analyze scenarios like spectrum handoff in overlay cognitive radio networks, the authors need to capture the status change of the target channels in a more realistic manner. Most of the existing cognitive radio channel models assume target channels to be busy only when occupied by primary users. However, in...

    Applying Dataflow and Transactions to Lee Routing

    Programming multicore shared-memory systems is a challenging combination of exposing parallelism in their program and communicating between the resulting parallel paths of execution. The burden of communication can introduce complexity that is hard to separate from the pure expression of the algorithm and can negate the performance that is gained...

    What's Wrong And Right With Microfinance - Missing An Angle On Responsible Finance?

    Microfinance as the best way of tackling poverty is under attack. It has been accused of failing to help the poor, of treating its clients badly, of charging high interest rates and of encouraging poor people to take on excessive debt burdens. The authors examine these issues, and find that...

    Checking Flight Rules With TRACECONTRACT Application of a Scala DSL for Trace Analysis

    Typically during the design and development of a NASA space mission, rules and constraints are identified to help reduce reasons for failure during operations. These flight rules are usually captured in a set of indexed tables, containing rule descriptions, rationales for the rules, and other information. Flight rules can be...

    Discrete Time Analysis of Cognitive Radio Networks With Saturated Source of Secondary Users

    The strategy used for sensing in a cognitive radio network affects the white space that Secondary Users (SUs) perceive and hence their throughput. For example, let the average time interval between consecutive sensing be fixed. There are several possible ways to achieve this mean value. The SU may sense the...

    TRACECONTRACT: A Scala DSL for Trace Analysis

    In this paper, the authors describe TRACECONTRACT, an API for trace analysis, implemented in the SCALA programming language. They argue that for certain forms of trace analysis the best weapon is a high level programming language augmented with constructs for temporal reasoning. A trace is a sequence of events, which...

    Lost in Translation: Data Integration Tools Meet the Semantic Web

    More information is now being published in machine processable form on the web and, as de-facto distributed knowledge bases are materializing, partly encouraged by the vision of the Semantic Web, the focus is shifting from the publication of this information to its consumption. Platforms for data integration, visualization and analysis...

    Capital Regulation, Monetary Policy And Financial Stability

    This paper examines the roles of bank capital regulation and monetary policy in mitigating procyclicality and promoting macroeconomic and financial stability. The analysis is based on a dynamic stochastic model with imperfect credit markets. Macroeconomic (financial) stability is defined in terms of the volatility of nominal income (real house prices)....

    The Innofusion Of Electronic Banking In Indonesia

    Even though financial innovation plays an important role in the modern economy, surprisingly there have been few empirical literatures. In developing countries, electronic banking (e-banking), for example, received relatively little attention although has been deployed for years. Indonesia presents unique case of Asian tiger economies, especially after experiencing crisis, financial...

    User Feedback as a First Class Citizen in Information Integration Systems

    User feedback is gaining momentum as a means of addressing the difficulties underlying information integration tasks. It can be used to assist users in building information integration systems and to improve the quality of existing systems, e.g., in dataspaces. Existing proposals in the area are confined to specific integration sub-problems...

    Microfinance Regulation And Social Protection

    Arguably, micro-finance provides social protection for the vulnerable by enabling them to access finance, create assets and avoid backsliding into poverty traps. This paper aims to survey the status quo of regulation of micro-finance services in Africa and to map out patterns of micro-finance regulation. The paper explores the relationship...

    A Kernel Technique For Forecasting The Variance- Covariance Matrix

    The forecasting of Variance-Covariance Matrices (VCMs) is an important issue in finance, having applications in portfolio selection and risk management as well as being directly used in the pricing of several financial assets. In recent years an increasing body of literature has developed multivariate models to forecast this matrix; these...

    Regime Shifts In Mean-Variance Efficient Frontiers: Some International Evidence

    Regime switching models have been assuming a central role in financial applications because of their well-known ability to capture the presence of rich non-linear patterns in the joint distribution of asset returns. This paper examines how the presence of regimes in means, variances, and correlations of asset returns translates into...

    Microfinance And Poverty A Macro Perspective

    This paper tests the hypothesis that microfinance reduces poverty at macro level using cross-country and panel data, based on the Microfinance Information EXchange (MIX) data on MFIs and the new World Bank poverty estimates. Taking account of the endogeneity associated with loans from MFIs, the authors' econometric analysis shows that...

    A Cholesky-MIDAS Model For Predicting Stock Portfolio Volatility

    This paper presents a simple forecasting technique for variance covariance matrices. It relies significantly on the contribution of Chiriac and Voev (2010) who propose to forecast elements of the Cholesky decomposition which recombine to form a positive definite forecast for the variance covariance matrix. The method proposed here combines this...
