The present study aims at constructing Confidence Intervals (C.I) for the predicted values of a Time Series with the application of a Hybrid method. The presented methodology is complicated and thus is completed in different stages. Initially the Artificial Neural Networks (ANNs) is applied on the raw time series in order to estimate C.I of the forecasts. Then, the Bootstrap method is employed on the residuals generated by the preceded process. On the upper and lower limit of the estimated C.I., two new ANNs are employed in order to make point estimations (of the upper and lower limits) using of Object Oriented programming. For the empirical analysis daily observations of the closing prices of Alpha Bank stocks have been used. The sample period is extended from 28/01/2004 until 30/11/2005. The nonstationarity of the time series employed in our study is not a forbidding condition for the estimation of the confidence intervals, in our case, since the level of bootstrap still provides a satisfactory approximation for the roots arbitrarily close to unity (Berkowitz, Kilian 1996). The accuracy of the forecasts was surveyed with the use of different criteria and the results were satisfactory.

There are many visual programming languages for education but they are poorly used in German schools as most do not fit the requirements of the various curricula. This paper introduces a new visual programming language called Puck, that has been developed at the Friedrich Schiller University, Jena, in accordance with the wishes of teachers in Thuringia (a federal state of Germany). The visualisation in Puck is based on text-based programs, but syntax errors are prevented through the use of a visual system. Data types, variables, control structures, procedures and parameters can be taught with Puck. In addition, with code generation for Oberon-2, Java and pseudocode, students can be prepared for textual programming. Puck combines ideas from other visual programming languages and adds new features, such as the creation of correct expressions through context menus and a complexity calculation for a program.

programming takes designers away from typical domainand task-based interfaces such as three-dimensional modellers. It thus imposes additional cognitive load on the already challenging design task. programming in the model is a system design strategy that embeds the act of programming in a 3D CAD model. This paper presents the argument for programming in the model and two user interface constructs that support such programming.

Purpose - The aim of this paper is to introduce a new technique for convection visualization. This is similar to Bejan's heatlines and is even an exact match to Landau and Lifshitz's energy streamlines for two-dimensional geometries. Design/methodology/approach - The work benefits from a combination of numerical and analytical tools to show that, in two-dimensional space, heatlines and energy streamlines are effectively the same. More importantly, the energy flux vectors are tracing both of them accurately;as verified for some cases of free and forced convection problems in this paper. Findings - The new technique is easier to implement compared to the existing counterparts which are available in the literature. More specifically, the advantage of this new technique is that, contrary to heatlines and energy streamlines, it does not require further numerical analysis in addition to solving momentum and energy equations. Originality/value - Energy flux vectors offer higher resolution compared to existing visualization tools.

Monaco is a domain-specific language for machine automation programming. It has been developed with the objective to empower domain experts with limited programming capabilities. Its main language features are an imperative notation for reactive systems, concepts for describing asynchronous event handling in a. concise way, and a state-of-the-art component approach. Monaco is a programming language with a Pascal-like syntax, but also comes with a visual programming environment. In. this paper we review the language Monaco, show the visual representation scheme, report on the programming environment and compare our visual notation to Statecharts.

There is a growing need for custom visualization applications to deal with the rising amounts of volume data to be analyzed in fields like medicine, seismology, and meteorology. visual programming techniques have been used in visualization and other fields to analyze and visualize data in an intuitive manner. However, this additional step of abstraction often results in a performance penalty during the actual rendering. In order to prevent this impact, a careful modularization of the required processing steps is necessary, which provides flexibility and good performance at the same time. In this paper, we will describe the technical foundations as well as the possible applications of such a modularization for GPU-based volume raycasting, which can be considered the state-of-the-art technique for interactive volume rendering. Based on the proposed modularization on a functional level, we will show how to integrate GPU-based volume ray-casting in a visual programming environment in such a way that a high degree of flexibility is achieved without any performance impact.

In this paper we propose frameworks and tools supporting a Statecharts-based development of JADE-based multi-agent systems (MASs) with the purpose of providing an effective approach for engineering MASs and leveraging agent-oriented development methodologies and processes adopting JADE as target agent platform. In particular, a framework for programming JADE behaviors through a variant of the Statecharts, named Distilled StateCharts (DSCs), has been first developed by enhancing the JADE add-on HSMBehaviour. Then, to enable rapid prototyping of JADE agents, a visual tool for DSCs has been extended with translation rules based on the developed framework which allows to automatically translate DSC specifications into DSC-based JADE behaviors. The proposed approach is exemplified through a case study concerning an agent-based meeting organization system.

Stix is a platform managing emerging large-scale broadband wireless access (BWA) networks. It has been developed to make it easy to manage such networks for community deployments and wireless Internet service providers while keeping the network management infrastructure scalable and flexible. Stix is based on the notions of goal-oriented and in-network management. With Stix, administrators graphically specify network management activities as workflows, which are deployed at a distributed set of agents within the network that cooperate in executing those workflows and storing management information. We implement the Stix system on embedded boards and show that the implementation has a low memory footprint. Using real topology and logging data from a large-scale BWA network operator, we show that Stix is significantly more scalable (via reduction in management traffic) compared to the commonly employed centralized management approach. Finally we use two case studies to demonstrate the ease with which Stix platform can be used for carrying out network reconfiguration and performance management tasks, thereby also showing its potential as a flexible platform to realize self-management mechanisms.
