Electricity has become a vital part of the modern life. Ever increasing electricity demand and inefficiency of the old electricity grid have led to the new vision which is called smart grid. Since, much work has been done to study the different aspects of the smart grid using computer and mathematical models. However little is done to combine those efforts to study the smart grid and ecodistrict in the same context. In this work we discuss the importance of the smart grid technologies in an ecodistrict development and the theoretical approaches for modeling smart grid and ecodistrict. Further more, we propose an agent-based model of ecodistricts with smart grid elements, by following a modeling approach called ASPECS. Though the simulations based on this kind of models can not be used as an exact predictive tools, it provides us with an exploratory tool to study how to integrate smart grid elements in an ecodistrict, and how different actors interact with each other.

Designing interactive applications is a complex and error-prone activity, because of the importance of the human-computer interaction aspect. For the same reason, thoroughly testing such applications is particularly important and requires a lot of effort. Automating this activity can result to significant development cost reduction and quality improvement. This paper presents a research work aiming at defining a test modeling language for interactive applications based on task trees, called TTT. The objective of the TTT language is to provide a means for expressing abstract test scenarios for interactive applications, including non-deterministic choices and action occurrence probabilities that can be used to automate the test generation.

In this paper, we present fast approaches for object segmentation and surface restoration of indoor 3D point clouds, which are the results of 3D reconstruction methods or range scanners. These two problems are significant in constructing a augmented reality system using a range camera to build a virtual environment and provide the interaction mechanisms to the virtual model. For point-cloud segmentation, we apply a density-based clustering algorithm to extract the desired object after removing its ground planes. This low-complexity method gives stable results with high accuracy. After the segmented object has been removed, a restoration algorithm is proposed in such a case that the holes on the ground plane are revealed by removed objects. These holes are there because the corresponding surfaces are hidden by the segmented objects in the scanner phase. The process of filling the holes includes an object-ground-plane detection, a geometric restoration and a color fusion step. The newly added points are directly interpolated from the existing object points, which cover the holes in the original point clouds. Our approaches are experimented through a variety of test datasets and yield promising results.

In this paper, we propose a method that uses both semantic rules and machine learning to extract infectious disease events in Vietnamese electronic news, which can be used in a real-time system of monitoring the spread of diseases. Our method contains two important steps: detecting disease events from unstructured data and extracting information of the disease events. The event detection uses semantic rules and machine learning to detect a disease event; in the later step, Name Entity Recognition (NER), rules, and dictionaries are used to capture the event's information. The performance of detection step is ≈77,33% (F-score) and the precision of extraction step is ≈91,89%. These results are better that those of the experiments in which rules were not used. This indicates that our method is suitable for extracting disease events in Vietnamese text.

Keyword search is a user-friendly way to retrieve information from XML and relational database (RDB). There have been many approaches proposed for keyword search over XML and RDB. However, the existing approaches cannot fully exploit hidden semantics in XML document or RDB. This causes serious problems in processing some class of keyword queries. In this paper, we thoroughly point out mismatches between answers returned by existing approaches and the expectations of common users. Through detailed analysis of these mismatches, we show the importance of semantics in keyword search over XML and RDB and propose a semantics-based approach for processing XML and RDB keyword queries. Particularly, we propose to use Object Relationship (OR) data graph and Object Relationship Mixed (ORM) data graph, which fully capture semantics of object, relationship and attribute, to represent XML document and RDB respectively, and we develop algorithms based on the proposed data model to return more comprehensive answers.

Major researches in the domain of complex systems are interdisciplinary, collaborative/participative and geographically distributed. Therefore, the simulation of complex systems is usually a collaborative/participative work that highly demands the exchange, from distance, of participants. However, most of the actual simulators cannot support this exchange. In this paper, we will present a new method to create a participatory simulator supporting the collaboration/participation from distance in the complex system participatory simulation. The method includes: (i) a collaborative software infrastructure, named PAMS, containing common collaborative tools (videoconferencing, instant messaging, and many other communication tools) and specific tools dedicated to the simulation domain (sharing experiments, results, experience exchange and various type of manipulation tools) and (ii) a role-based meta-model facilitating the integration of actual simulators into PAMS.

Integrated environmental modeling approaches, especially agent-based modeling ones, are increasingly used in large-scale decision support systems. A major consequence of this trend is the manipulation and generation of a huge amount of data in simulations, which require to be efficiently managed. In this paper, we present a Combination Framework of Business intelligence solution and Multi-agent platform (CFBM) and its implementation on the GAMA platform. CFBM is a logical framework dedicated to the management of the input and output data of simulations, as well as the corresponding empirical datasets in an integrated way and the analysis on integrated data, which we propose as a coupling of two major methodologies: Multi-Agent Simulation (MAS) on one hand and Business Intelligence (BI) solution on the other. An integrated model of a surveillance network and Brown Plant Hopper (BPH) invasion is presented. This model is used throughout the paper as a case study of CFBM regarding to the database accesses, the integration of internal and external processing, and the model validation tasks. We show how the proposed combination framework can be an appropriate choice for all decision-support systems with a huge data, hence the modelers can be also encouraged to develop the big model in a large scale.

Client-server application model has several drawbacks such as server bottleneck and weak scalability. Peer-to-Peer (P2P) model resolves these problems by distributing tasks on the nodes participating in the system. P2P application development and protocol designing are much more difficult than client-server model. This paper proposes an approach to take the advantages of both models: the scalability of the P2P model and the simplicity of the client-server model. This paper presents a hybrid P2P and client-server model to achieve both goals based on caching mechanism which allows using cache content not only on a single client, but for all clients in the system. The proposed model has been applied to implement a Web application.

Dramatic paradigm shifts over the past few centuries have led to a rich landscape of options in human and machine communication. Communication today is deeply intertwined with our personal and social lives in addition to being a vital part of businesses and government operations---both overt and covert. This talk will address the evolving role that the fundamental laws of quantum physics are likely to play in giving communication yet another dimension in its richness. Quantum communication will bring about not only communication in the form as we know it, but also ensure that it is unconditionally secure as it transits through any medium. Given that information is the currency of a modern society, its security is paramount for the wellbeing of an individual, a society, a nation, or the globe as a whole. The talk will discuss the short history of quantum communication and draw upon the theoretical and experimental work that the author and his colleagues have conducted over the past few years in order to chart out the likely course of future events in the emerging age of secure communication.

In the era of information explosion, a program is necessary to be scalable. Therefore, scalability analysis becomes very important in software verification and validation. However, current approaches to empirical scalability analysis remain limitations related to the number of supported models and performance. In this paper, we propose a runtime approach for estimating the program resource usage with two aims: evaluating the program scalability and revealing potential errors. In this approach, the resource usage of a program is first observed when it is executed on inputs with different scales, the observed results are then fitted on a model of the usage according to the program's input. Comparing to other approaches, ours supports diverse models to illustrate the resource usage, i.e., linear-log, power-law, polynomial, etc. We currently focus on the computation cost and stack frames usage as two representatives of resource usage, but the approach can be extended to other kinds of resource. The experimental result shows that our approach achieves more precise estimation and better performance than other state-of-the-art approaches.
