    Networks Utilization Improvements for Service Discovery Performance

    Service discovery requests' messages have a vital role in sharing and locating resources in many of service discovery protocols. Sending more messages than a link can handle may cause congestion and loss of messages which dramatically influences the performance of these protocols. Re-send the lost messages result in latency and...

    Financial Capability, Income And Psychological Wellbeing

    The authors examine whether financial capability has impacts on psychological health independent of income and financial resources more generally using a nationally representative survey. British Household Panel Survey data are used to construct a measure of financial capability, which they relate to respondents' psychological health using the 12-item General Health...

    A Driven Backup Routing Table to Find Alternative Disjoint Path in Ad Hoc Wireless

    The performances of the routing protocols are important since they compute the primary path between source and destination. In addition, routing protocols need to detect failure within a short period of time when nodes move to start updating the routing table in order to find a new primary path to...

    Robust IPTV Delivery With Adaptive Rateless Coding Over a Mobile WiMAX Channel

    As intelligent content management of IPTV moves popular material nearer to the end-user, application-layer channel coding schemes, involving the retransmission of extra redundant data, become attractive as a result of the reduced latency. Application-layer, adaptive rateless channel coding is exploited in this paper's scheme to reconstruct streamed video across an...

    Multiple Mental Thought Parametric Classification: A New Approach for Individual Identification

    This paper reports a new approach on identifying the individuality of persons by using parametric classification of multiple mental thoughts. In the approach, ElectroEncephaloGram (EEG) signals were recorded when the subjects were thinking of one or more (up to five) mental thoughts. Autoregressive features were computed from these EEG signals...

However, in the hands of trained constraint problem solvers, the same constraints that create the problems in the first place can also guide problem solvers to solutions. Constraint satisfaction is all about learning how to flow with the force of the constraints. Examples...

    Capital Structure With Opportunistic Stakeholders' Coalitions

    This paper shows that stakeholders' multilateral opportunistic behavior during financial distress may lead to premature liquidation of the firm. Consequently, the firm will use its capital structure to mitigate the costs of such opportunism. Specifically, the firm will reduce its debt so that the probability of multilateral opportunism is zero;...
