We show that digital holography can be combined easily with optical coherence tomography approach. Varying the reference path length is the means used to acquire a series of holograms at different depths, providing after reconstruction images of slices at different depths in the specimen thanks to the short-coherence length of light source. A metallic object, covered by a 150-microm-thick onion...

A 47-year-old male was referred to Emergency Department of our hospital for acute urinary retention. Physical examination showed electrical cable with proximal part introduced into the urethra. Plain abdominal radiograph demonstrated a metallic object in the pelvis and the patient underwent an operation. We used suprapubic cystostomy approach, and the wire was removed from the bladder and urethra.

Low and non-metallic landmines are one of the most difficult subsurface targets to be detected using several geophysical techniques. Ground penetrating radar (GPR) performance at different field sites shows great success in detecting metallic landmines. However significant limitations are taking place in the case of low and non-metallic landmines. Electrical resistivity imaging (ERI) technique ...

This paper applies duration calculus to the speciication and ver-iication of a complex robotics task: Fingers grasping an object. We present a model of the relevant features of the mechanical design and provide a speciication for sensors, actuators and a controller. Requirements are then speciied in an assumption commitment style, and it is checked through calculation that the design satisses t...

The notion of \speciication" plays a key role in the developing science of computing. It is typically considered to be the keystone in the software development process. However, there is no single, generally agreed meaning of \speciication" that bears close scrutiny. Instead there is a variety of diierent, although partially interlocking and overlapping interpretations of the term. We catalogue...

We investigate the use of nanopatterned metallic films as transparent conductive electrodes in optoelectronic devices. We find that the physics of nanopatterned electrodes, which are often optically thin metallic films, differs from that of optically thick metallic films. We analyze the optical properties when performing a geometrical transformation that maintains the electrical properties. For...

We consider a general GMM framework where weaker patterns of identi cation may arise: typically, the data generating process is allowed to depend on the sample size. We are interested in providing inference about the identi cation of the structural parameter. First, we propose a consistent Hausman-type test to test whether additional moment conditions enhance its identi cation. Failing to rejec...

A technique of measuring contact resistance between an individual nanotube and a deposited metallic film is described. Using laser ablation to sequentially shorten the contact length between a nanotube and the evaporated metallic film, the linear resistivity of the nanotube as well as the specific contact resistivity between the nanotube and metallic film can be determined. This technique can b...

A study of the [C6 H6 Ir(PH3 )3 ]+ iridatropylium cation structure based on frontier orbital analysis, thermodynamic analysis, and natural bond orbital (NBO) theory is the main aim of the present research. Also, HOMO, LUMO energies, hardness, electrophilicity and chemical potential were calculated. Structural analysis indicated the optimized geometry shows a good agreement with the experimental...

in this study the binding abilities of 1,3-calix[4]biscrown-6 (l) toward ba2+ and ca2+ have beenestablished in methanol by spectrophotometric measurements at 25±0.1 °c and 0.01 m ionicstrength, and with using specfit computer program; stability constants for 2 : 1, metal : ligandcomplexes has been estimated
