in order to assess the influence of breed on the vertebral heart scale (vhs) of dogs, the vhs was measured and compared in left to right (ll) and right to left lateral (rl) views. for all dogs (n=56), the mean vhs on the rl radiographs [9.7 vertebra (v)] was significantly larger than the mean vhs on the ll radiographs (9.6 v) (p=0.047). doberman dogs had higher mean values of the vhs in ll (9.9...

Resin Transfer Molding, as a method for the manufacture of advanced ber reinforced composite materials, is attractive because it ooers the possibility of lower manufacturing costs and more complex shapes than the traditional manufacturing methods. A major issue in this new manufacturing process is the elimination of void spaces in the resin ll operation, so that products with high quality are m...

An improved numerical algorithm for front tracking method is developed to simulate the rising of a bubble in quiescent viscous liquid due to buoyancy. In the new numerical algorithm, volume correction is introduced to conserve the bubble volume while tracking the bubble’s rising and deforming, and volume flux conservation based SIMPLE algorithm is adopted to solve the Navier–Stokes equation for...

This paper presents a low-profile user-terminal antenna for mobile bi-directional Ka-band satellite communication networks for emergency scenarios. We have devised an antenna with a circularly polarised radiation pattern and dual-band capability, which addresses a hybrid tracking. The principle of operation of a rectangular antenna panel applying a dual-band partially reflective surface (PRS) o...

Locata positioning technology was developed to address the shortcomings of current technologies for reliable positioning in challenging environments such as when GPS satellite coverage is poor or not available. Previous research in this area has demonstrated proof-of-concept for the Locata technology using a first generation prototype system. In this paper details of Locata’s next generation sy...

In an ideal case telepresence achieves a state, where a human operator can no longer di erentiate between an interaction with a real environment or a technical mediated one. This state is called transparent telepresence. The applicability of telepresence to on-orbit servicing (OOS), i.e. an unmanned servicing operation in space, teleoperated from ground in real time, is veri ed in this paper. F...

Automated road information extraction enables the ready creation, maintenance, and update of the transportation network databases used for traffic management and automated vehicle navigation. This paper presents a semi-automatic method for road network extraction from high-resolution satellite images. First, we focus on detecting the seed points in candidate road regions using a Kohonen-type se...
