Minimal paths (MPs) play an important role in network reliability evaluation. In this paper, we report an efficient recursive algorithm for finding all MPs in two-terminal networks, which consist of a source node and a sink node. A linked path struct

For a planetary gear set, the transducer-perceived vibration signal contains vibration information from multiple sources including the sun gear, planet gears, and the ring gear. All these vibration sources are subject to corresponding transmission pa

In most of literatures of age replacement policy, failures before planned replacement age can be either minimally repaired or perfectly repaired based on the types of failures, cost for repairs and so on. In this paper, we propose age replacement pol

Derating is the operation of an item at a stress that is lower than its rated design value. Previous research has indicated that reliability can be increased from operational derating. In order to derate an item in field operation, however, an engine

Non-thermal ultrasonics and thermosonication of Taylor’s Gold pear, Royal Gala apple and Camarosa strawberry purees were carried out to inactivate polyphenoloxidase (PPO), the enzyme that causes fruit browning. The PPO thermosonication (0.6 and 1.3

A general method for reliability evaluation of multistate network is using minimal path vectors. A minimal path (MP) vector to system state d is called a d-MP. Most reported works on generating d-MPs are for a particular d value. However, if all d-MP

The rotating speed information is significant for condition-based monitoring of rotating machines which are often operated under varying speed conditions. To automatically extract rotating speed from vibration signals, a deep learning model named man
