the central alborz mountains of northern iran (figure 1) is a zone of intense active continental deformation and is the most heavily populated region of iran, including the mega-city of tehran with a population of over 10 million. the region is affected by numerous active faults, some of them having great seismic potential, and documented historical seismicity. hence, the central alborz is a pr...

Abstract. Normal incidence seismic data provide the best images of crust and lithosphere. When properly designed continuous, these sections greatly contribute to understanding geometry orogens and, along with surface geology, unraveling their evolution. In this paper we present most complete transect, date, Iberian Massif, westernmost exposure European Variscides. Despite heterogeneity dataset,...

This paper deals with the handling of deformable linear objects (DLOs), such as hoses, wires or leaf springs, bases on force/torque sensing. First, we describe the characteristic change of force and moment for all single-contact transitions which may occur between DLO and a rigid polyhedron obstacle. Second, we present data processing algorithms for the automated detection of state transitions ...

We want to describe a procedure for enlarging real vector spaces to complex vector spaces in a natural way. For instance, the natural complex analogues of Rn, Mn(R), and R[X] are Cn, Mn(C) and C[X]. Why do we want to complexify real vector spaces? One reason is related to solving equations. If we want to prove theorems about real solutions to a system of real linear equations or a system of rea...

Throughout his prolific publishing career Conrad Gessner composed abundant paratexts which offer valuable insight into his methods of working. Gessner wrote many dedications, only a minority of which were addressed to major patrons of his day. Instead he used them to thank dozens of physicians and scholars for sending him information, images, and manuscripts for his ongoing projects. Gessner ac...
