−− This paper addresses the problem of testing continuous-time nuclear-pulse shapers using Oscillation-Based Test (OBT). The proposal is to convert the whole systems into non-linear oscillators, avoiding the partition in low-order sections. The design of the oscillators is very simple because the nonlinear elements are mathematically modeled using the describing function approach, and the study...

This paper discusses a probabilistic methodology for detecting permanent or transient functional changes in the statetransition mechanism of a deterministic finite-state machine (FSM). The associated detector observes the frequencies with which states are occupied and detects faults by analyzing the deviation between the expected frequencies and the actual measurements. In addition to state occ...

The High Redundancy Actuator project deals with the construction of an actuator using many redundant actuation elements. Whilst this promises a high degree of fault tolerance, the high number of components poses a unique challenge from a control perspective. This paper shows how a simple robust controller can be used to control the system both in nominal state and after faults. To simplify the ...

Backgrounds: Syndactyly is failure of differentiation in which the fingers fail to separate into individual appendages. It most common congenital hand anomaly, with an incidence 1 2,000 2,500 live births. Surgical separation as early 6 month-old indicated when syndactyly involves digits unequal length (i.e., ring and little fingers). Early also required complex cases acrosyndactyly. The timing ...

The move towards nanoscale circuits poses new challenges to circuit design. As the dimensions shrink, it is becoming increasingly difficult to control the variance of physical parameters in the manufacturing process, for instance the concentration of dopants, the thickness of the gate and the insulation oxides, the width and thickness of metal wires, etc. This results in decreased yield which i...

estimation. APE's solution to the parameter estimation problem is to estimate only those parameters associated with the proposed fault, thereby reducing the computation and focussing fault diagnosis. Within APE, Qmimic and QMI fault diagnosis can be accomplished in several ways, and we have examined two methods: deening all fault models in advance (QMI), or creating new models based on the faul...

In this paper, a state space model is developed to describe the dimensional variation propagation of multistage machining processes. A complicated machining system usually contains multiple stages. When the workpiece passes through multiple stages, machining errors at each stage will be accumulated and transformed onto the workpiece. Differential motion vector, a concept from the robotics field...

A geothermal power plant projected in Unterhaching, south of Munich/Germany, will generate 3.36 MW of electrical power. Two boreholes (doublet) have developed the karstified Malm at a depth of approx. 3000 m. Available seismic profiles were reprocessed with the aim of interpreting the facies and thus the degree of karstification within the Malm. The most prospective areas are, beside fault zone...

The NNW-trending Dena Fault, with 140 km length, cuts the major structures of Zagros Fold-Thrust Belt in Borujen region. The fault has divided the region in two zones, in which different structural, andmorphological features as well assedimentation and seismtectonic characteristics have developed. This study presents a new interpretation for the kinematics of Dena Fault based on field evidence....
