US Army Research Laboratory researchers designed a head-up display (HUD) that overlays driving information on a switchable vision block. Bradley and Stryker drivers were surveyed for recommendations to incorporate in the prototype. A simulation experiment was conducted to evaluate a HUD versus a traditional head-down display (HDD). Results about driving task performance were mixed, with the HUD...

The aim of this research was to develop an efficient and accurate method to fabricate a dental implant surgical guide. The surgical guide is adapted from the patient's vacuum-formed clear template with the use of a plate with three ceramic balls, a six-axis drilling machine and its fixture. The plate, with the ceramic balls used as radiographic markers, is glued to the template, and the patient...

Borehole cleaning is still a major challenge for most directional wells despite significant progress achieved in drilling fluids, tools and field practice, as well the development of academic industry research. Insufficient borehole causes undesirable phenomena form various complications. Therefore, purpose conducted research was to present main correlations that determine nature degree annular...

Effective gas management is vital to the success of the longwall mining in the Bulli seam, in the Southern Coalfield, Sydney Basin, NSW, Australia. The evolution of gas drainage methods and practices are discussed with respect to gas type, gas drainage lead time and prevailing geological conditions. Both underground to inseam drilling and surface to inseam drilling techniques are described at b...

In this paper, we propose a robust method to register a panoramic range data obtained by a panoramic laser range finder and an omni-directional image acquired by a stereo omni-directional system (SOS), by matching the horizontal and vertical edge histograms of the two images. The proposed method first estimates the relative horizontal rotation angle by matching the vertical edge histograms. Nex...

automatic facial recognition has many potential applications in different areas of humancomputer interaction. however, they are not yet fully realized due to the lack of an effectivefacial feature descriptor. in this paper, we present a new appearance based feature descriptor,the local directional pattern (ldp), to represent facial geometry and analyze its performance inrecognition. an ldp feat...
