Wireless networks, such as 5G (and future 6G) networks, can recognize opportunities to enhance message performance by analyzing fault types in real-time, and selecting an appropriate mitigating modulation table accordingly. Noise patterns causing adjacent-amplitude faults and adjacent-phase faults indicate the need for different modulation schemes, while the large non-adjacent faults from pulsed external interference lead to yet a different choice. Disclosed examples show how to select an appropriate mitigating modulation table through fault analysis of failed messages. By selecting and switching to different modulation tables according to the types of message faults experienced by user messages, network operators can reduce message failure rates and increase overall throughput while reducing average delay per message, according to some embodiments.

The disclosure provides a tension leg platform (“TLP”) with a plurality of buoyant pontoons suitable for highly disturbed seas that can expand the stability of the tension leg platform by extending at least one buoyant pontoon beyond an intersection of two pontoons. In at least one embodiment, the location of the column can be decoupled from the customary end of the pontoon. The tendons can be located at the ends of the pontoons extending beyond the intersection.

The performance and durability of compressor wheels coupled to turbocharger shafts are at odds with each other in that a higher rotational speed can be accommodated by an aluminum compressor wheel. But, aluminum has a low yield strength which causes the compressor wheel to expand outwardly at high rotational speeds such that the slip fit on the shaft no longer prevents wobble at high rotational speeds. To at least partially address this issue, the compressor wheel has two portions: an inner portion made of steel or titanium that has a relatively higher yield strength and a blade portion made of a lightweight, castable material. The inner portion is manufactured with grabbing features on its periphery, placed in a die, and the blade portion is cast over the grabbing features to yield a compressor wheel of two materials that provides sufficient shaft stiffening without high rotational inertia.
