Given a multi-dimensional Markov diffusion X, the Malliavin integration by parts formula provides a family of representations of the conditional expectation E[g(X2)|X1]. The different representations are determined by some localizing functions. We discuss the problem of variance reduction within this family. We characterize an exponential function as the unique integratedvariance minimizer amon...

Normally, the communication in the earth surface is through electromagnetic or radio waves. But this is not possible in the underwater environments in an efficient way. In underwater environments radio does not work well due to its quick attenuation in water. Hence the acoustic signals are sent using the acoustic channels. If the communication is done with retransmission, it gives rise to the p...

Due to the importance of longest path analysis in networks of queues, we develop an analytical method for computing the steady-state distribution function of longest path in acyclic networks of queues. We assume the network consists of a number of queuing systems and each one has either one or infinite servers. The distribution function of service time is assumed to be exponential or Erlang. Fu...

In practical situations, distribution network loads are the mixtures of residential, industrial, and commercial types. This paper presents a hybrid optimization algorithm for the optimal placement of shunt capacitor banks in radial distribution networks in the presence of different voltage-dependent load models. The algorithm is based on the combination of Genetic Algorithm (GA) and Binary Part...

Multimedia Content distribution is playing an increasingly prominent role in the Internet today, with a proliferation of diverse services and delivery mechanisms. Due to this increasing heterogeneity the management of next generation content networks is becoming increasingly complex. This paper presents Juno, a configurable component-based middleware designed to address the divergent nature of ...

Quantum Key Distribution (QKD) is a secure key distribution technology, which provides information theoretic or unconditional security. BBN DARPA quantum network and SECOQC network of secrets are the examples of such networks. Research is also in progress for the integration of QKD with the protocols in different layers of OSI model. Integration of QKD in point-to-point protocol (PPP) OSI layer...

Modern aircraft increasing rely on electric power, resulting in high safety-criticality and complexity in their electric power generation and distribution systems. Motivated by the resulting rapid increase in the costs and duration of the design cycles for such systems, we investigate the use of formal specification and automated, correct-byconstruction control protocols synthesis for primary d...

Planing the operation in modern power systems requires suitable anticipation of load evolution at different levels of distribution network. Under this perspective, load forecasting performs an important task, allowing the optimization of investments and the adequate exploitation of existing distribution networks. This paper describes the models developed for current intensity forecasting at pri...

Modern groupware systems serve as universal information sharing platforms by providing manifold capabilities for customization and extension of their core functionalities. In this paper we introduce a set of extension modules that were developed in the context of the ‘Distribution networks Relationship Management’ (DRM) project2 to support distribution networks of industrial small and medium si...

Many recent generative models make use of neural networks to transform the probability distribution of a simple low-dimensional noise process into the complex distribution of the data. This raises the question of whether biological networks operate along similar principles to implement a probabilistic model of the environment through transformations of intrinsic noise processes. The intrinsic n...
