Triangular meshes are often used to represent surfaces, at least initially, one reason being that meshes are relatively easy to generate from point cloud data. However, we often want a smoother surface representation, and hence the need arises to fit a smooth parametric surface through the vertices of the mesh. This requires making a suitable parameterization. Parameterizations are also useful ...

Felix, as he was known to his friends and colleagues, was born in New York City on February 4, 1948. He graduated from Stuyvesant High and Brooklyn College. Here, he was elected to Phi Beta Kappa and received his Bachelor of Science degree magna cum laude and the Jonas Scholarship with which he attended Yale School of Medicine. After leaving Yale, he spent almost three years as a fellow in the ...

Efficient and one-pot synthesis of 1,8-dioxo-octahydroxanthenes was described by Knoevenagel condensation, Michael addition and cyclodehydration of dimedone. This reaction was carried out through condensation of dimedone and various aromatic aldehydes in the presence of task-specific Brønsted acidic ionic liquid under solvent free conditions. The catalyst could be recycled five times without si...

The MICHAEL PRIZE was awarded for the first time in 1963 to stimulate epilepsy research in Germany; it is now one of the most highly regarded international awards for the best contribution to scientific and to clinical research which promote further development in epileptology. The MICHAEL PRIZE is awarded biennially and specially designed to attract younger scientists (normally not older than ...

For the best contribution to scientific and clinical research that promotes further development in epi-leptology. The MICHAEL PRIZE is one of the most highly regarded international awards for the best contribution to scientific and clinical research promoting further developments in epileptology; it is awarded biannually and specially designed to attract younger scientists (under 45 years of ag...

Michael J. Ryan is the Clark Hubbs Regents Professor in Zoology in the Section of Integrative Biology, University of Texas, Austin, USA, and a Research Fellow at the Smithsonian Tropical Research Institute in Panama. His main research has been on sexual selection and communication and his 1985 book The Túngara Frog: A Study of Sexual Selection and Communication has become a classic in that fiel...

In this paper, new attacks against TKIP based IEEE 802.11 networks are described. Using the known Beck-Tews attack, we define schemas to continuously generate new keystreams, which allow more and longer packets to be injected. Also an attack against the Michael message integrity code is presented, that allows an attacker to reset the internal MIC state and building on top of that, concatenating...
