This paper presents the operation principle and development of a micromachined thermal convective inclination sensor using Carbon Nanotube (CNT) sensing elements. The operation principle of this type of inclination sensor is based on sensing the convection of fluids in a micro chamber. External motion will lead to redistribution of the temperature profile around a heater and will be asymmetric....

Dipole sonic log data recorded in a vertical pilot well and the associated production well are analyzed over a 200 × 1100-ft section of a North American gas shale formation. The combination of these two wells enables angular sampling in the vertical direction and over a range of inclination angles from 54° to 90°. Dipole sonic logs from these wells show that the formation’s average properties a...

Obese populations present challenges for acetabular cup placement during total hip arthroplasty (THA). This study examines the accuracy of acetabular cup inclination and version in the obese patient with robotic-assisted computer navigation. A total of 105 patients underwent robotic-assisted computer navigation THA with a posterior approach. Groups were divided on body mass index (BMI, kg/m(2))...

Manually powered hand tricycles are commonly used vehicles used by the mobility challenged for conveyance and transportation in India. However, the existing models are inadequate in many essential features. The authors have developed a new design, which can be configured according to the user’s requirement and comfort. The features that are adjustable are the driving mechanism, seat height, and...

We compare two derivations of a popular formula for the tidal despinning rate, and emphasise that both are strongly limited to the case of a vanishing inclination and a certain (sadly, unrealistic) law of frequency-dependence of the quality factor. One method is based on the MacDonald torque, the other on the Darwin torque. Fortunately, the second approach is general enough to accommodate both ...

The effect of inlet humidity conditions and inclination angle on the air side thermal hydraulic performance of a brazed aluminum heat exchanger has been investigated experimentally. The crossflow heat exchanger had flat tubes and folded fins with fin and louver pitch of 2.1 mm and 1.4 mm, respectively. The glycol temperature was held nearly isothermal at 1C, while humidity of the 12C inlet air ...
