Discrete-time unscented Kalman filter: Comprehensive study of stochastic stability
No full textDimirovski, Georgi M. (Dogus Author) -- Conference full title: Itzhack Y. Bar-Itzhack Memorial Symposium on Estimation, Navigation, and Spacecraft Control : Book of abstracts : Dan Panorama Hotel, Haifa, Israel, October 14-17, 2012.The performance of the Unscented Kalman Filter (UKF) for a class of general nonlinear stochastic discretetime systems is investigated in this paper. It is proved that the estimation error of the UKF remains bounded provided a under certain conditions are satisfied. It is further shown that the estimation error remains bounded provided the system satisfies the nonlinear observability rank condition. Furthermore, it is shown that the design of noise covariance matrix plays an important role in improving the stability of the UKF algorithm. These results are verified by simulations for a given illustrative example of an inherently nonlinear plant.Doğuş Üniversitesi, Technion--Israel Institute of Techlnology
Particles at Nematic Liquid Crystal Interfaces
No full textInternational audienceLiquid crystal (LC) colloidal dispersions have been shown to promote complex ordered organizations due to the local distortion of the host by the particles and the resulting long-range elastic interactions mediated by the Frank elasticity. The key components responsible for these colloidal patterns have been well understood at the micron scale and are now increasingly studied at the sub-micron scale. One of the main challenges in order to design useful colloidal dispersions in a nematic however remains the fine control of the multipolar elastic interactions. The attractive components are indeed usually sufficiently strong to lead to a rapid aggregation of dispersed particles. We will first discuss some strategies to prevent this phenomenon in bulk. We will also discuss the case of particles trapped at liquid crystal interfaces where the elastic interactions are strongly modified by the confinement [1,2] but also might compete with capillary interactions, as we detailed recently [3]. When confined at LC interfaces, spherical particles with homeotropic anchoring interact with repulsive interactions only, then forming regular arrays with large lattice parameters. When they are confined in a thin nematic film the colloidal behaviour is much more complex depending on the boundary conditions at the interfaces. For example we have shown that the capillary attraction expected for particles confined in thin films with hybrid anchorings is counteracted by the nematic texture and the presence of topological defects.[1] M.A. Gharbi, M.

The Narrative Strategies of Nationalism in Returning to Haifa by Ghassan Kanafani
No full text이 글에서는 갓산 카나파니의 소설 ｢하이파에 돌아와서｣(Returning to Haifa)에 나타난 내셔널리즘 서사 전략을 분석하고자 한다. 1969년의 팔레스타인 상황에서 소설을 통해 내셔널리즘을 강화하고자 한 작가의 기획이 성공적으로 드러나는 면과 실패하는 국면을 함께 살펴봄으로써 내셔널리즘의 한계를 고찰하려는 것이 이 글의 목적이다. 이를 위해 이 글에서는 다음의 두 가지에 초점을 맞추었다. 첫 번째는 내셔널리즘을 강화하고자 한 이야기 형식을 살펴보는 것이고, 두 번째는 내셔널리즘의 타자들이 소설에서 어떤 방식으로 그려지는가 하는 점이다.
갓산 카나파니의 이력은 조국에서의 추방과 인접 아랍국들을 전전하는 피난생활 등 팔레스타인 인민들의 운명과 그 궤를 함께 한다. 1948년에 그는 12세의 나이로 다른 팔레스타인 사람들과 똑같이 피난길에 오르
게 되어, 레바논, 시리아, 쿠웨이트, 베이루트 순으로 옮겨다녔다. 문학저술 외에도 교사, 언론인, 정치가로 활동해 온 그는 PELP(팔레스타인 인민 해방전선) 대변인으로 활동하던 중 자동차 폭파 사고로 목숨을 잃었다. 뚜렷한 정치적 이력과 함께 그는 장편소설 세 편, 희곡 한 편, 그리고 50편이 넘는 단편소설을 남겼다.
This thesis deals with the narrative strategies of Nationalism in Returning to Haifa written by Ghassan Kanafani. He intended to strengthen Nationalism by dealing with the Palestinian situation in 1969 in his novel. The objective of this thesis is to understand the limitations
of Nationalism by looking into the successes and failures of what he intended to.
In this novel who we can see a narrator, who assimilated with a character in the novel, who considers the others as his enemies and suppress them in an authoritative manner, which implies what Nationalism is. In addition, we can see a unique structure where the Nationalism that the author
intended to highlight is reinforced, while three returning narratives are overlapped. However, the irony is, we can notice that the authors messages with the monophonic voice become weaker when we pay attention
to the otherness that is eventually exposed. The narrative strategies of Nationalism start to rupture at this point where the imagination to resolve the Israeli Palestinian issue can newly created
Nakba and Survival
No full textBeginning in 1948, Israeli paramilitary forces began violently displacing Palestinian Arabs from Palestine. Nakba and Survival tells the stories of Palestinians in Haifa and the Galilee during, and in the decade after, mass dispossession. Manna uses oral histories and Palestinian and Israeli archives, diaries, and memoirs to meticulously reconstruct the social history of the Palestinians who remained and returned to become Israeli citizens. This book focuses in particular on the Galilee, using the story of Manna’s own family and their village Majd al-Krum after the establishment of Israel to shed light on the cruelties faced by survivors of the military regime. While scholars of the Palestinian national movement have often studied Palestinian resistance to Israel as related to the armed struggle and the cultural struggle against the Jewish state, Manna shows that remaining in Israel under the brutality of occupation and fighting to return to Palestinian communities after displacement are acts of heroism in their own right.
“Nakba and Survival is bound to be the standard authoritative study of the 1948 war in the city of Haifa and the Galilee.”—Salim Tamari, coauthor of Camera Palaestina: Photography and Displaced Histories of Palestine
“Essential reading for anyone wishing to understand how the events of 1948 continue to shape the Palestinian condition today.”—Maha Nassar, author of Brothers Apart: Palestinian Citizens of Israel and the Arab World
“The empathy for, and solidarity with, Adel Manna’s historical subjects shapes the book’s narratives, the questions it asks, and its deft use of oral histories. A must-read for all those who want to understand daily lives under settler colonial rule.”—Orit Bashkin, coeditor of Jews and Journeys: Travel and the Performance of Jewish Identit

Elastocapillarity in thin nematic films
No full textInternational audienceby solid substrates, the particle creates a hyperbolic hedgehogdefect, usually located near the bead (at a distance of order of its size) and the pair particle-defectforms a neutral unit, stable in time. Here we show theoretically and experimentally how capillaryeffects strongly modify the behaviour of particles trapped in a thin nematic film with hybrid anchoringconditions at free surfaces. For a certain range of thickness values (films thinner than the particles’size) two new interesting patterns are formed by isolated particles: the giant dipole [3] and the“butterfly” texture (see Fig.1). In the giant dipole, a micron-sized sphere is accompanied by a pointdefect which is located at a distance up to several hundreds microns. The situation is quite different inthe “butterfly” texture: the particle still produces an accompanying defect in its close neighbourhood,but a p-wall is formed on the opposite side. Using spatially resolved retardation and easy-axis maps,we analysed quantitatively and separately the 2D interfaces deformation and the nematic textures.Both behaviours are due to the same axisymmetric capillary deformation of the thin film around thebeads but with different boundary conditions for the polar 2D c-director. Using a simple 2D Ansatz,we were able to reproduce the c-director patterns found in the films. The local 3D textures have beenalso investigated in the framework of the Landau-de Gennes theory. Although capillary interactionsbetween inclusions in a thin film are always attractive [4], these new spontaneous organizations in thinnematic films offer new ways to self-assemble complex colloidal systems in 2D.Figure1: The two different birefringence patterns formed by microparticles trapped in a thin nematicfilm, observed a) between crossed polarizers and b) with an Abrio birefringence measurement system.[1] I.
