Let f(x, y) be a real polynomial of degree d with isolated critical points, and let i be the index of grad f around a large circle containing the critical points. An elementary argument shows that |i| ≤ d − 1. In this paper we show that i ≤ max{1, d − 3}. We also show that if all the level sets of f are compact, then i = 1, and otherwise |i| ≤ dR − 1 where dR is the sum of the multiplicities of...

The doctoral symposium at MODELS'14 took place in Valencia, Spain on Septem-ber 30, 2014. It received 16 submissions, all of which were reviewed by 3 members of the program committee. This committee was composed of the symposium chair and grad students who presented their work in the Doctoral symposium in MODELS'13. Out of the 16 submissions, 11 were accepted and presented during symposium. Aut...

Im medizinischen Fachbereich der Anästhesie ist die Informationsverarbeitung an der Erkrankung des Patienten orientiert. Die zu erfassenden Informationen orientieren sich streng an der Erkrankung und dem Grad der Erkrankung des Patienten. Aufgabe eines Anästhesie-Informationssystems ist die Verarbeitung der Gesamtheit aller Informationen, die generell in der Anästhesie zu dokumentieren sind. Mo...

Modellbasierte Softwareentwicklung wird zunehmend gängige Praxis. Da immer umfangreichere Modelle arbeitsteilig in Teams entwickelt werden, sollte das parallele Bearbeiten von Modellen durch ähnliche Mischfunktionen unterstützt werden, wie man es für textuelle Dokumente gewohnt ist. Wir analysieren zunächst die technischen Randbedingungen bei der modellbasierten Softwareentwicklung; demzufolge ...

The present paper proves that all limit points of sequences of renormalized solutions of the Boltzmann equation in the limit of small, asymptotically equivalent Mach and Knudsen numbers are governed by Leray solutions of the Navier-Stokes equations. This convergence result holds for hard cutoff potentials in the sense of H. Grad, and therefore completes earlier results by the same authors [Inve...

Evidence grids provide a uniform representation fo r fusing temporally and spatially distinct sensor readings. However, the use of evidence grids requires that the robot be localizeo! within its environment. Odometry errors typically accumulate over time, making localization estimates degrade, and introducing significant errors into evidence grads as they are built. W e have addressed this prob...

The Goddard Earth Sciences (GES) Data and Information Services Center (DISC) is undertaking an architectural upgrade of its GES-DISC Interactive Online Visualization ANd aNalysis Infrastructure or "Giovanni" to take it from a synchronous CGI application to an asynchronous Web services workflow management system. Because Giovanni has been enormously successful from a user standpoint, increased i...

In this article, we address the implementation of a distributed data system designed to serve Earth system scientists. Recently, a consortium led by George Mason University has been funded by NASA’s Working Prototype Earth Science Information Partner (WP-ESIP) program to develop, implement, and operate a distributed data and information system. The system will address the research needs of seas...

Introduction: The endoscope is an equipment used successfully in several procedures of several medical specialties. However, in the otology area, even with incorporation of endoscopes in joint procedures with microscope, the procedures purely assisted by endoscopy are still very limited. Objective: Our work is aimed at carrying out transcanal and modified transcanal endoscopic dissection of the...

Due to the rapid development of motor vehicle Driver Assistance Systems (DAS), the safety problems associated with automatic driving have become a hot issue in Intelligent Transportation. The traffic sign is one of the most important tools used to reinforce traffic rules. However, traffic sign image degradation based on computer vision is unavoidable during the vehicle movement process. In orde...
