Signs of microbial life on Mars, if they exist, will probably exist underground. This paper describes a robotics system for handling and sub-sampling cores taken from a robotic drill. The system prepares samples for analysis and life detection experiments. This system has been integrated with a drill and other instruments and tested in the field. This paper presents a description of the system ...

This paper proposes a Graph semantic based Object Oriented Multidimensional Data Model (GOOMD). The model defines a set of graph based formal constructs that are used to specify the conceptual level design of data warehouses (DW). Besides offering a novel graph based semantic for multidimensional data representation, the proposed GOOMD model renders a unified realization of different logical st...

Drilling tools currently used in surgery depends only on the surgeon’s manual skills to stop the penetration when completing a hole. This paper presents a modular mechatronic system for automatic bone drilling in surgery. The development of a “modular system” that is compatible with motor-driven drills that are commercially available, rather than developing a new surgical drill, is emphasized. ...

• Oil, gas, and geothermal exploration benefit from drill bit monitoring • Bits are expensive and may be damaged by high temperature or pressure • Bit orientation can be monitored to help guide bore hole • State of the art: mud modulation • Mud used to cool and lubricate drill bit • Collar near bit chokes flow to relay signal • Pressure sensor at surface decodes • Effective but slow, unidirecti...

SAS/GRAPH® software enables you to summarize your data and present a summary using various charting options and view it from different directions. Drill down graphs let you slice and dice ONLY what you see in the main chart. To literally drill into a graph for additional information and charting, further coding is required, but easy to do. The method presented makes a chart vastly more dynamic....

This paper investigates an approach that combines ensemble methods with graphical models to analyse multiple sensor measurements in the context of mine automation. Drill sensor measurements used for drilling automation have the potential to provide an estimate of the subsurface geological properties of the rocks being drilled. A Boosting algorithm is used as a local classifier mapping drill mea...

A highly skilled surgical technic is an important factor for the success of implant. But the heat generation during bone preparation will greatly affect the healing process of bone and prognosis of implant. In this study, the heat occurrence and distribution during bone preparation which performed on an in vitro mandible model (ribs of pig) were considered with the aid of a real-time thermograp...

The effects of reinforcement and extinction on response variability and stimulus generalization in the punching and kicking techniques of 2 martial arts students were evaluated across drill and sparring conditions. During both conditions, the students were asked to demonstrate different techniques in response to an instructor's punching attack. During baseline, the students received no feedback...

Improving the welfare of nonhuman animals in captivity and maintaining behavioral competence for future conservation purposes is of the highest priority for zoos. The behavior of an aggressive male drill (Mandrillus leucophaeus poensis) was assessed in Barcelona Zoo. The 2-year study presented in this article examined the effects of introducing changes in the exhibit of the drill to improve his...
