Engineering of medical informatics systems is a complex work because it is at the intersection of several critical domains, among which medicine, computer science, electrical engineering to mention just a few. One critical aspect of such systems is the interoperability of the different components. One key solution for the interoperability is the creation of good standards that will assure the interchange...
Assisted living and home monitoring systems are gradually becoming a necessity, considering the current trends in population ageing and older adults' desire to continue living independently in their homes and their communities for as long as possible. This paper presents our current achievements regarding the implementation of a cyber-physical system for assisted living and home monitoring, developed...
The work of this p aper is done within the context of European Project E! 8949 PrEmISES 1. One of the central pieces of PrEmISES[16] is the use of automatic tool generation algorithms for the creation of ontologies. The objective of this work is to extend the work from PrEmISES for raising the medical literacy of empowered patients by creating a digital library that contains relevant articles from...
Today digital medical imaging starts to be more introduced in the daily practice for clinical, educational, research uses. The work reported in this paper is done within the context of the Research Project UEFISCDI No. 31/2014, “AIMMS - Application for Using Image Data Mining and 3D Modeling in Dental Screening”. AIMMS provides an integrated platform to support dental treatment methods using the most...
The work of this paper is done within the context of European Project E! 9770 i-Light, which aims at developing intelligent systems based on smart luminaries for building monitoring. The work presented in this paper extends the work from i-Light project towards a smart guiding system for buildings. The system is based on the use of smart luminaries and drones. One of the main targets of such a system...
The opportunities offered by mobile technology continue to expand with the advances in wireless broadband. These days there are a lot of entrenched business solutions, upgraded for mobile devices, which likewise have direct use to services of the government services, work environment practices and involvement of stakeholders. Each advance has challenges. The usage of M-Government will bring several...
i-Light is a home-monitoring system that enables a pervasive, seamless, and inexpensive monitoring scheme. It is researched and implemented as part of a European Union funded project and it will achieve pervasive monitoring by means of a novel energy efficient luminaire equipped with an embedded sensing, indoor localization and communications electronic system, luminaire that is developed as part...
The objective of this paper1 is to present a framework that helps small and medium enterprise to exploit their available informational space. While large enterprises contains dedicated information management departments and software, the actual software framework implementations lack orientation towards small and medium companies with fewer employees and smaller budget. We propose a framework implementation...
This paper is made within the context of the research UEFISCDI project no. 31/2014, “AIMMS — Application for Using Image Data Mining and 3D Modeling in Dental Screening”. The project is interdisciplinary and wants to build a system framework composed of several sub-systems: dental pathology recognition part, 3D printing part, user interface part. The main emphasis of this article regards the pathology...
Molecular dynamics facilitates the simulation of a complex system to be analyzed at molecular and atomic levels. Simulations can last a long period of time, even months. Due to this cause the graphics processing units (GPUs) and multi-core systems are used as solutions to overcome this impediment. The current paper describes a comparison done between these two kinds of systems. The first system used...
Our paper is addressing an actual need of the modern society, which is to take advantage of Internet of Things for creating smart environments in order to improve everyday life. We propose a solution for helping the design of smart environments by letting the user test different topologies, without the actual equipment, in order to find out the best configuration for transforming the house into a...
Indoor positioning systems are becoming a required sub-system in many ambient assisted living scenarios. Also IoT (Internet of Things) device interaction would greatly benefit from the enriched context of localization. However, at this moment there is not a satisfying technology or approach for precise indoor positioning. In our paper we test the accuracy for Wi-Fi and Bluetooth Low Energy RSSI measurements...
Our paper presents the first phase in developing an indoor localization technique based on WiFi for patient monitoring scenarios in patient empowerment and ambient assisted living settings. We describe an experiment that measures the accuracy for positioning using WiFi signals and the results show that decent accuracy can be obtained using existing equipment and with a minimum setting effort.
In this paper, we explore the possibilities to detect and label straightforward the teeth in Cone Beam Computed Tomography images, without performing complex segmentation procedures on teeth. We are using the Circular Hough Transform (CHT) to find the teeth positions, segmentation using intensity level to determine the mandible and deformable templates to find the best fit position for the teeth on...
MSC is a visual formalism for specifying the behavior of systems. To obtain implementations for individual processes, the MSC choice construction poses fundamental problems. The best-studied cause is non-local choice, which e.g. is unavoidable in systems with autonomous processes. In this paper we characterize two additional problematic classes of choice nodes. Based on these three classes we point...
In this paper we present a technique for the Spin tool, inspired by practical experiences with Spin and a FireWire protocol. We show how to guide simulations with Spin, by constructing a special guide process that limits the behaviour of the original system. We set up a theoretical framework in which we prove under some sufficient conditions that the adjusted system (with the added guide process)...
Currently, communication protocols for medical devices are being developed for the IEEE 1073.2 standard. The protocol description in its draft remote control package consists of a collection of intended behaviors in terms of MSCs. We have contributed to actually constructing the protocol, ranging from determining an hMSC for these MSCs, via synthesizing process implementations, to integrating it with...
Edge detection is an important task in image processing, many times as part of the segmentation process. When segmentation is performed in medical imaging, one of the preferred tools is neural networks, because of their capabilities of adaptive learning and non-linear mapping. We present in this paper the neural network tools used for edge detection and we propose one that is able to perform edge...
Molecular dynamics (MD) studies the structure of molecular systems which are subject to certain constraints and forces. The simulation of particles is a tool for examining atomic systems during a period of nanoseconds in which the trajectory of atoms and the state of the system is analyzed. GROMACS is a package which supports molecular dynamics simulations and energy minimization, being started the...
The algorithm described in this paper is part of a program supporting the process of teeth contour detection, segmentation and 3D reconstruction. The data is taken from dental conical tomographies. Automatic contour detection starts by filtering the image according to an adaptive threshold. The region of interest is established and the tooth contour is determined using the possible edge directions...
