    Postoperative infection after elective arthrodesis of the interphalangeal joint is an uncommon complication often necessitating urgent debridement. We present the rare case of a female patient with a history of oral herpetic lesions, who underwent elective arthrodesis of the middle and index fingers for treatment of erosive osteoarthritis and subsequently developed a postoperative herpetic infection at the surgical site

    LIMO EEG: A Toolbox for hierarchical LInear MOdeling of ElectroEncephaloGraphic data

    Get PDF
    Magnetic- and electric-evoked brain responses have traditionally been analyzed by comparing the peaks or mean amplitudes of signals from selected channels and averaged across trials. More recently, tools have been developed to investigate single trial response variability (e.g., EEGLAB) and to test differences between averaged evoked responses over the entire scalp and time dimensions (e.g., SPM, Fieldtrip). LIMO EEG is a Matlab toolbox (EEGLAB compatible) to analyse evoked responses over all space and time dimensions, while accounting for single trial variability using a simple hierarchical linear modelling of the data. In addition, LIMO EEG provides robust parametric tests, therefore providing a new and complementary tool in the analysis of neural evoked responses

    The Matlab Vectorization Paradigm

    We give two examples of application of a vectorized programming paradigm: binary addition and cycle decomposition of directed graphs

    Optimization of toolpath trajectories on arbitrary surfaces

    Get PDF
    Given an arbitrary region on the plane, modelled as a graph with a symmetry, we describe a procedure to find the best orientation for slicing, via a zigzag tool-path trajectory based curve, in order to minimize its discontinuities. We also develop some directions on how to generalize the procedure up to the level of optimizing tool-path trajectories on arbitrary surfaces rather than planar regions only

    Finite orbit decomposition of endomaps

    In this work we present a vectorized Matlab algorithm for the decomposition of an endomap into its finite orbits

    Computer tool for maximizing the placement of congruent polyhedra

    Get PDF
    Given multiple identical polyhedral objects and a parallelepiped container, how should one place the objects so that the largest number fits inside the container? This simple question is important in many applications, yet the answer is elusive. In fact, we know of no published solution for this very general formulation. Still, in many circumstances, further restrictions apply, resulting in a large number of variations requiring different algorithmic strategies. This paper is the continuation of [12] and focus on the fundamental concepts and tools that are used for this kind of problem, such as the no-fit polygon. We also present some of its many variations, giving in particular one that applies to the stereolithographic rapid prototyping technology

    Computer construction of platonic solids

    In this paper we develop a novel method to generate a 3D geometrical model from 2D planer images. As an example of application, we construct 3D models of each one of the five platonic solids from their platonic graphs

    Assessing the mixing performance of extruders: indices and scale-up

    Get PDF
    This work proposes the use of global quantitative dispersive and distributive mixing indices to characterize the performance of a given screw. Calculation of these quantities uses a model of morphology evolution as a function of material and flow characteristics, which was coupled to a description of the flow developing along the screw from hopper to die. Scale-up on the basis of these indices is briefly discussed. Some results are presented in order to illustrate the usefulness of the methodology

    Capture of UAVs through GPS spoofing using low-cost SDR platforms

    Get PDF
    The increased use of unmanned aerial vehicles (UAVs), better known as drones, by civilians has grown exponentially and their autonomous flight control systems have improved significantly, which has resulted in a greater number of accidents and dangerous situations. To help resolve this problem, in this paper, we address the use of low-cost Software Defined Radio (SDR) platforms for simulating a global navigation satellite system (GNSS), more specifically the global positioning system (GPS), in order to transmit false signals and induce a location error on the targeted GPS receiver. Using this approach, a defensive system can be implemented which can divert, or even take control of unauthorized UAVs whose flight path depends on the information obtained by the GPS system.info:eu-repo/semantics/acceptedVersio
