Development and Investigation of Minimum Power Non-contact Swirl Vane Gripper
Abstract: The Swirl vane gripper is a new non-contact gripper, which uses negative pressure created by the air swirling flow to create an upward lifting force. This upward force can be used to lift an object, which is placed underneath the gripper. In comparison with other non-contact grippers, this gripper is electrically actuated (rather than pneumatically) and hence require less power to generate same lifting force as produced by other grippers. …

Evaluation of Acceleration Signal Frequency Results on Bearing Shell Non-destructive Testing, Ultrasonic Waves, Simulation
Abstract: Bearings are used in many rotary machines. Defects in them can cause car breakdowns, loss of production, and even catastrophic accidents. This makes them difficult to maintain and will make it costly to repair and maintain. Therefore, detecting defects in bearing vibrations is an important issue for the industry. On the other hand, error-related frequencies may be identified as discrete frequency lines, and therefore error characteristics cannot be easily identified.For …

Comparison of Ultra Wide Band Indoor Multipath IEEE 802.15.3 Channel Model
Abstract: ABSTRACT A very large bandwidth of frequency (3.1–10.6 GHz) has been allocated to UWB systems. A single-band UWB signal propagates differently in the lower and upper bands of the spectrum due to the size of its bandwidth. The lower part of the signal can be obstructed more easily and the man-made interferences are not homogeneously distributed over the whole spectrum. The first experimental results obtained for a UWB channel show …
