  • A complete and permanent hydrophilic modification of poly (ethyleneterephthalate) (PET) films is achieved by argon-plasma irradiation, subsequently grafting acrylic acid (AA) in vapor phase onto their surface. Both Ar plasma irradiation alone and post grafting AA rendered a complete hydrophilicity to PET surfaces. However, the hydrophilicity of the PET surface, only treated with the Ar plasma, is not permanent. In contrast, PET films, irradiated by the Ar plasma, exposed to air, and subsequently grafted with AA monomer, are permanently hydrophilic. Degradation of polymer chains on the plasma-irradiated surface is proportional to time of exposure. Electron spectroscopy for chemical ana...

  • In the manufacturing processes of high-power laser diode modules, the module packaging technologies play an important role; decide the efficiency of the electro-optical conversation, the beam quality and the lifetime. This paper presents the packaging of high-power laser diode modules from single chip, evaluating the electro-optical characteristics and the beam quality of the modules. The obtained results show that the packaged module has an output optical power of 5 W at current 5.9 A; the Operation Voltage is 1.7 V; the Threshold Current is 1,0 A; the Divergence Angle Mean is 36.8 degree and the Asymmetry is 1.04. These parameters are almost the same that of some on-stock modules. ...

  • n Chap. 1, we insist that a nonlinear equation shouldnotbe considered as the pertur-bation of a linear equation. We illustrate using two simple examples the importanceof taking account of the singularity structure in the complex plane to determine thegeneral solution of nonlinear equations. We then present the point of view of thePainlev ́e school todefine new functionsfrom nonlinear ordinary differential equa-tions (ODEs) possessing a general solution which can be made single valued in itsdomain of definition (Painlev ́e property, PP).In Chap. 2, we present a local analysis, called thePainlev ́etest, in order to in-vestigate the nature of the movable singularities (i.e. whose locatio...

  • Nguyên đại Paleozoi (hay nguyên đại Cổ sinh) là một giai đoạn lớn trong lịch sử Trái Đất kéo dài gần 300 triệu năm (bắt đầu từ cách nay 542 tr. năm và kết thúc cách nay 251 tr. năm). Paleozoi là nguyên đại đầu của Liên nguyên đại Phanerozoi, tiếp nối nguyên đại Neoproterozoi và sau nó là nguyên đại Mesozoi (Trung sinh) rồi đến Kainozoi (Tân sinh). Nét đặc trưng của nguyên đại này là có thế giới sinh vật cổ xưa, tên gọi nguyên đại Paleozoi hay nguyên đại Cổ sinh cũng thể hiện đặc điểm này – tên gọi Paleozoi xuất phát từ tiếng Hy Lạp cổ: palaios (παλαιός) là “cổ xưa” và zoe (ζωή) – “sự sống”). Nhờ phát hiện nhiều hóa thạch bảo tồn tốt trong đá mà lịch sử Paleozoi được nghiên cứu chi ti...

  • A Palmprint Identification System using Robust Discriminant Orientation Code.pdf.jpg
  • Article


  • Authors: Hoang, Van Thien; Le, Thai Hoang (2014)

  • This paper presents a palmprint recognition system in which we propose a novel acquisition device and a Robust Discriminant Orientation Code, called RDORIC, for palmprint identification. In order to get the clear line features, the device is designed to capture the palmprint images under Green illuminations. To extract RDORIC feature, we present the algorithm which includes two main steps: Palm line orientation map computation and Discriminant feature extraction of the orientation map. In the first step, positive rientation and negative orientation maps are computed by applying the modified finite Radon transform (MFRAT). In the second step, the grid-sampling based 2DLDA, called Gri...

  • Actuellement, plusieurs recherches dans le domaine du système complexe sont interdisciplinaires et collaboratifs. Elles associent des scientifiques venant de différents domaines de recherche. De plus, les chercheurs sont souvent géographiquement distribués. Pour ces raisons, l’échange entre les scientifiques est difficile. Le but de notre travail est d’explorer une nouvelle approche de collaboration scientifique qui facilite l’interaction dans le processus de modélisation et la simulation. L’originalité de l’approche est considérée des modèles et des simulateurs comme un panneau de la collaboration : un objet partagé qui est manipulé par un groupe de scientifiques. Dans ce cont...

  • Orthogonal Frequency Division Multiplexing (OFDM) systems support high data rate wireless transmission, offer excellent immunity against fading and intersymbol interference. The major drawback of OFDM is large Peak to Average power Ratio (PAR) of the transmit signals. As consequence, the power amplifier has to be highly linear. Most power amplifiers are non-linear and produce spectral distortion in the adjacent channel of the OFDM-spectrum. There are several methods for reducing the PAR in OFDM systems. This paper investigates Tone Reservation (TR) method of J.Tellado.
