System reliability

Rolling bearing faults have been capturing substantial research attention as they are the root causes of malfunctions in mechatronics systems than any other factors. The detection of rolling bearing faults in the early stage is therefore a mandatory requirement demanded by reliable industrial plants.

Seismic analysis of soil-structure interaction (SSI) is a challenge due to the nonlinearities of soil-foundation interaction (SFI). The reliability of the design and the analysis results will suffer if SSI is ignored. In this paper, a two-step method based on the superposition theorem is used to perform a seismic analysis of a soil-foundation-tank-liquid system (soil-liquid tank system).

In this study, MCS is applied to compute the reliability of the nodes and the network under uncertain demand and roughness, and to determine how reliability is distributed among the various nodes of WDN, as well as assessing the reliability of the network as a series or parallel system. The effect of the resilience index on the nodal and network reliability is also assessed.

In this thesis, focus on the wireless links between devices equipped by deployed operating personnel and intermediary access point infrastructure. We use multi-radio (MR) platforms, wireless devices with multiple and diverse transceiver technologies, to produce robust and reliable links through adaptive control of available transceivers. Primarily, we study the application of intelligent control techniques, namely reinforcement learning (RL), for adaptive control over diverse transceivers to achieve the desired robustness and reliability under dynamic environmental conditions.

The main aims of the project were to firstly find out or identify barriers that are inhibiting builders from installing greywater systems and secondly to identify and formulate strategies to reduce or eliminate the barriers identified. The main barriers for builders are; high cost, government regulations, lack of builder awareness or knowledge, and low client demand.

This thesis has proposed two systems: the RIM-OFDM system with diversity reception exploits simultaneously the frequency and spatial diversity to achieve better SEP performance than the conventional IM-OFDM with diversity reception; The RIM-OFDM system with CI attains higher reliability and flexibility than the conventional IM-OFDM-CI system. The low-complexity detectors were also proposed to reduce the complexity while still achieve nearly same performance of the ML detector.

In this research, a bi-objective hybrid vehicle routing problem is presented and solved by considering alternative paths, various lengths and reliabilities. The first objective function minimizes overall system costs, fuel consumption, and greenhouse gas emissions, whereas the second objective function maximizes the reliability of the entire system with alternative paths and several reliabilities.

The Hitachi SV1100 utilizes capillary electrophoresis on a microchip that is capable of rapidly sizing DNAfrag-ments. Reproducibility of electrophoresis in different channels was shown by comparing the migration times of the internal controls, DNAfragments of 100 and 800 bp. The range of DNAsizing for this microchip is between 100 and 800 bp, and accuracy in sizing of a 322 bp DNA fragment of a pUC118 PvuII digest was observed, inde-pendent of DNAconcentration. Although relatively good quantification of this fragment was observed with a DNA concentration of 1.
