Authors: Cayo Pabllo, Rafael Soto, Jorge Campos
Venue: Proceedings of the 2008 Euro American Conference on Telematics and Information Systems (2008)

Mistakes during the administration of medication process are one major source of deaths and injuries caused by medical errors at hospitals. The use of mobile computing can seriously contribute to reduce this statistic and to improve the satisfaction of the public and healthcare professionals with the medical system. This paper presents a framework to develop mobile applications for the healthcare domain. The framework considers aspects that vary from the specification of the user interface to the integration of the mobile application with enterprise resources. This paper also presents a prototype of medication administration application developed under the proposed framework.
Tool Support for Holistic Modelling of Distributed Embedded Systems in Creol
Authors: Marcel Kyas
Venue: Electronic Notes in Theoretical Computer Science (ENTCS) (2009)

A holistic approach to modelling embedded systems is advocated: Many aspects of a system should be analysed in isolation to keep the task manageable, but they often influence each other during integration in a way that the desired system becomes unrealisable. A tool-supported approach that aims at integrated models of different concerns based on formal methods is suggested to solve this problem. This approach uses Creol, which is a language designed for object-oriented modelling of distributed systems. We report on ongoing work on the design and the implementation of tools that support modelling, validation, and verification. We focus on sensor networks, which are distributed system that consists of many embedded devices with tight constraints on computational power, energy availability, and timeliness. The described tools are a compiler that performs static checks and optimisations, an interpreter that defines a formal semantics, and a prototypical LTL model checker. This supports seamless development with formal methods.

A Theoretical Analysis of the k-Satisfiability Search Space
Authors: Andrew M. Sutton, Adele E. Howe, L. Darrell Whitley
Venue: Proceedings of the Second International Workshop on Engineering Stochastic Local Search Algorithms. Designing, Implementing and Analyzing Effective Heuristics (2009)

Local search algorithms perform surprisingly well on the k-satisfiability (k-SAT) problem. However, few theoretical analyses of the k-SAT search space exist. In this paper we study the search space of the k-SAT problem and show that it can be analyzed by a decomposition. In particular, we prove that the objective function can be represented as a superposition of exactly k elementary landscapes. We show that this decomposition allows us to immediately compute the expectation of the objective function evaluated across neighboring points. We use this result to prove previously unknown bounds for local maxima and plateau width in the 3-SAT search space. We compute these bounds numerically for a number of instances and show that they are non-trivial across a large set of benchmarks.

A Multi-touch Tool for Co-creation
Authors: Geke D. Ludden, Tom Broens
Venue: Proceedings of the 12th IFIP TC 13 International Conference on Human-Computer Interaction: Part II (2009)

Multi-touch technology provides an attractive way for knowledge workers to collaborate. Co-creation is an important collaboration process in which collecting resources, creating results and distributing these results is essential. We propose a wall-based multi-touch system (called CoCreate) in which these steps are made easy due to the notion of connected private spaces and a shared co-create space. We present our ongoing work, expert evaluation of interaction scenarios and future plans.

Active Learning for Reward Estimation in Inverse Reinforcement Learning
Authors: Manuel Lopes, Francisco Melo, Luis Montesano
Venue: Proceedings of the European Conference on Machine Learning and Knowledge Discovery in Databases: Part II (2009)

Inverse reinforcement learning addresses the general problem of recovering a reward function from samples of a policy provided by an expert/demonstrator. In this paper, we introduce active learning for inverse reinforcement learning. We propose an algorithm that allows the agent to query the demonstrator for samples at specific states, instead of relying only on samples provided at "arbitrary" states. The purpose of our algorithm is to estimate the reward function with similar accuracy as other methods from the literature while reducing the amount of policy samples required from the expert. We also discuss the use of our algorithm in higher dimensional problems, using both Monte Carlo and gradient methods. We present illustrative results of our algorithm in several simulated examples of different complexities.

Venue: Proceedings of the International Conference on Ergonomics and Health Aspects of Work with Computers: Held as Part of HCI International 2009 (2009)

The purpose of this research is to emphasize on the concept of integrating computer and interactive technologies to the rehabilitation robotic with biofeedback. First, the robot is actuated with pneumatic muscle actuator which have interesting characteristics that can be exploited for upper limbed machines. The rehabilitation robotic system is using measurement which has two channels to detect and collect the rehabilitation robotic system from electromyography and the rotary encoder. Through PCI interface transferring the rehabilitation robotic system to personal computer, we can use our algorithms to attain real-time the force and/or contraction velocity of the muscle detection and other common information like the frequency of under muscle curve of user. Finally, the human-computer interface for rehabilitation system is designed. In this human computer interface consists of three main parts: detect the signal; a control scheme of robotic system combined with multimodal environment based biofeedback system; clinical database.

Venue: Proceedings of the 5th International on ConferenceUniversal Access in Human-Computer Interaction. Part II: Intelligent and Ubiquitous Interaction Environments (2009)

This paper describes the structure of real-time face detection hardware architecture for household robot applications. The proposed architecture is robust against illumination changes and operates at no less than 60 frames per second. It uses Modified Census Transform to obtain face characteristics robust against illumination changes. And the AdaBoost algorithm is adopted to learn and generate the characteristics of the face data, and finally detected the face using this data. This paper describes the hardware structure composed of Memory Interface, Image Scaler, MCT Generator, Candidate Detector, Confidence Mapper, Position Resizer, Data Grouper, and Overlay Processor, and then verified it using Virtex5 LX330 FPGA of Xilinx. Verification using the images from a camera showed that maximum 16 faces can be detected at the speed of maximum 30.

Venue: Proceedings of the 2008 10th International Symposium on Symbolic and Numeric Algorithms for Scientific Computing (2008)

In patients with cardiac artery disease myocardial perfusion scan, which is a non-invasive method, is utilized. This study is conducted to achieve an advantageous software applicable to quantitative myocardial SPECT perfusion. Each cross-section of the left ventricle is segmented by applying fuzzy clustering method. After obtaining the myocardial skeleton of the left ventricle from its short axis cross sections, we make use of fuzzy logic to decide whether the pixel belongs to myocardial muscle and any perfusion perturbation or not. Abnormal critical conditions in rest and stress studies and coronary artery disease diagnosis were investigated in a set of about 200 images. Measurement and allocation of different myocardial sectors to specific coronary arteries were accomplished by utilizing collected information about respectively 75 patient men and 62 patient women, and the validity of artery obstruction diagnosis has been proved in 40 patients having been under the coronary angiography. We named the achieved software DCAD(b) which has demonstrated a considerably good performance in coronary artery occlusion diagnosis and would be a promising method aiding nuclear medicine specialists in diagnosing these defections.
Symmetry-Aware Mesh Processing
Authors: A. Golovinskiy, J. Podolak, T. Funkhouser
Venue: Proceedings of the 13th IMA International Conference on Mathematics of Surfaces XIII (2009)

Perfect, partial, and approximate symmetries are pervasive in 3D surface meshes of real-world objects. However, current digital geometry processing algorithms generally ignore them, instead focusing on local shape features and differential surface properties. This paper investigates how detection of large-scale symmetries can be used to guide processing of 3D meshes. It investigates a framework for mesh processing that includes steps for symmetrization (applying a warp to make a surface more symmetric) and symmetric remeshing (approximating a surface with a mesh having symmetric topology). These steps can be used to enhance the symmetries of a mesh, to decompose a mesh into its symmetric parts and asymmetric residuals, and to establish correspondences between symmetric mesh features. Applications are demonstrated for modeling, beautification, and simplification of nearly symmetric surfaces.

A traditional goal of Artificial Intelligence research has been a system that can read unrestricted natural language texts on a given topic, build a model of that topic and reason over the model. Natural Language Processing advances in syntax and semantics have made it possible to extract a limited form of meaning from sentences. Knowledge Representation research has shown that it is possible to model and reason over topics in interesting areas of human knowledge. It is useful for these two communities to reunite periodically to see where we stand with respect to the common goal of text understanding. In this paper, we describe a coordinated effort among researchers from the Natural Language and Knowledge Representation and Reasoning communities. We routed the output of existing NL software into existing KR software to extract knowledge from texts for integration with engineered knowledge bases. We tested the system on a suite of roughly 80 small English texts about the form and function of the human heart, as well as a handful of "confuser" texts from other domains. We then manually evaluated the knowledge extracted from novel texts. Our conclusion is that the technology from these fields is mature enough to start producing unified machine reading systems. The results of our exercise provide a performance baseline for systems attempting to acquire models from text.

Venue: Proceedings of the sixth ACM international workshop on VehiculAr InterNETworking (2009)

Securing communication using broadcast authentication schemes (BAS) in V2V does not always guarantee exchange of correct and/or accurate information. Misbehavior Detection Schemes (MDS) are aimed at detecting the exchange of such information. In this paper, we propose a MDS for Post Crash Notification (PCN) application based on root-cause analysis that is capable of detecting different types of misbehaviors possible, for example, a false crash alert raised in the absence of a crash and a crash alert raised with incorrect positional information.

Venue: Proceedings of the 2009 Advanced Technologies for Enhanced Quality of Life (2009)

Introduction: Spine cord injuries arefrequent pathology in general population, which cause significant locomotor disabilities. Objective: We wanted to evaluate the clinical benefits of rehabilitation using natural factors (climate, sapropelic mud, salty water of the lake), applied to patients with spine cord injury. Material and method: We studied ( retrospective) patients with spine cord injury at first presentation in Techirghiol health resort, hospitalized from June, 1st 2007 to June, 1st, 2008, undergoing specific rehabilitation treatment and evaluated the clinical benefits of balneal treatment. Results: The first traumatic condition was fall down (37%), and the second car accident(14,4%). The most of them (84%)usewheelchair as support of travel and 30% needs accompanying standing. We noticed after the treatment improvement of muscle activity (both: spastic and flaccid) and psychological and muscle relaxation. Conclusions: Adequate administration of natural factors corroborate with progressive intensity of kinetotherapy or hydro-kineto-therapy completed with electrotherapy and massage lead to improvement of scores of patient. Quality of life of patients can increases in many ways: self esteem, interest for treatment, encouraging other patients, implication in family life and finding new means of support for travel and self assistance.
RATC: A Robust Automated Tag Clustering Technique
Authors: Ludovico Boratto, Salvatore Carta, Eloisa Vargiu
Venue: Proceedings of the 10th International Conference on E-Commerce and Web Technologies (2009)

Nowadays, the most dominant and noteworthy web information sources are developed according to the collaborative-web paradigm, also known as Web 2.0. In particular, it represents a novel paradigm in the way users interact with the web. Users (also called prosumers) are no longer passive consumers of published content, but become involved, implicitly and explicitly, as they cooperate by providing their own resources in an "architecture of participation". In this scenario, collaborative tagging, i.e., the process of classifying shared resources by using keywords, becomes more and more popular. The main problem in such task is related to well-known linguistic phenomena, such as polysemy and synonymy, making effective content retrieval harder. In this paper, an approach that monitors users activity in a tagging system and dynamically quantifies associations among tags is presented. The associations are then used to create tags clusters. Experiments are performed comparing the proposed approach with a state-of-the-art tag clustering technique. Results ---given in terms of classical precision and recall--- show that the approach is quite effective in the presence of strongly related tags in a cluster.

Challenges for Routing and Search in Dynamic and Self-organizing Networks
Authors: Gerhard Hasslinger, Thomas Kunz
Venue: Proceedings of the 8th International Conference on Ad-Hoc, Mobile and Wireless Networks (2009)

Search methods in self-organizing networks usually cannot rely on stable topology from which shortest or otherwise optimized paths through the network are derived. When no reliable search indices or routing tables are available, other methods like flooding or random walks have to be considered to explore the network. These approaches can exploit partial knowledge in the network to reach a destination, but the search effort naturally increases with the lack of precise paths due to network dynamics. This problem is especially relevant for wireless technology with strict limitation on power consumption/ We address the efficiency of random walks and flooding for exploring networks based on case studies evaluated by simulation and transient analysis. In this way, performance tradeoffs are demonstrated when combining shortest path routing with randomized techniques.
Multimodal references in GEORAL Tactile
Authors: Jacques Siroux, Marc Guyomard, Franck Multon, Christophe Rémondeau
Venue: Referring Phenomena in a Multimedia Context and their Computational Treatment (1997)

The paper specifically presents how linguistic (oral) and tactile references are dealt with in the GEORAL system which has already been described in other papers. In this system, users can formulate their queries and provide their responses using the oral (linguistic) modality and the tactile modality separately or together. We describe the referential phenomena which occur in such a context and we point out why the oral modality has to be the basis of the processing of the references and why robustness problems have to be dealt with. We then provide details about the three steps of the reference processing (linguistic analysis, processing of the tactile events and merging process) as well as the modeling of the communicative acts used in the system (as planning operators).
Relief analysis and extraction
Authors: Rony Zatzarinni, Ayellet Tal, Ariel Shamir
Venue: ACM SIGGRAPH Asia 2009 papers (2009)

We present an approach for extracting reliefs and details from relief surfaces. We consider a relief surface as a surface composed of two components: a base surface and a height function which is defined over this base. However, since the base surface is unknown, the decoupling of these components is a challenge. We show how to estimate a robust height function over the base, without explicitly extracting the base surface. This height function is utilized to separate the relief from the base. Several applications benefiting from this extraction are demonstrated, including relief segmentation, detail exaggeration and dampening, copying of details from one object to another, and curve drawing on meshes.
