Quantitative analysis of information flow is widely used to measure how much information was leaked from the secret inputs to the outputs or public inputs of a program. We propose to conduct the quantitative analysis of information flow within the trusted kernel of a higher-order-logic theorem prover in order to overcome the inaccuracy limitations of traditional analysis techniques used in this...

Based on the assumption of a uniform property annular-shaped region at the labyrinth entrance, this paper proposes a method for leakage flow rate prediction at the discharge end-face of twin-screw compressors. Assumption of such a region is the key aspect in the construction of an equivalent network of end-face leakage flows, in which the labyrinth entrance zone is a node. Using mass and energy...

A field-effect transistor is developed to control flow in microfluidic chips by modifying the surface charge condition. In this investigation, zeta potential at a particular location is altered locally by applying a gate voltage, while zeta potential at other locations is maintained at its original value. This non-uniform zeta potential results in a secondary electroosmotic flow in the lateral ...

A Bayesian system identification methodology is proposed for leakage detection in water pipe networks. The methodology properly handles the unavoidable uncertainties in measurement and modeling errors. Based on information from flow test data, it provides estimates of the most probable leakage events (magnitude and location of leakage) and the uncertainties in such estimates. The effectiveness ...

The gate-oxide (aka gate tunneling or gate) leakage due to quantum-mechanical direct tunneling of carriers across the gate dielectric of a device is a major source power dissipation for sub-65nm CMOS circuits. In this paper a high-level (aka architecture) synthesis algorithm is presented that simultaneously schedules operations and binds to modules for gate leakage optimization. The algorithm u...

A new approach to gas leakage detection in high pressure distribution networks is proposed, where two leakage detectors are modelled as a Linear Parameter Varying (LPV) system whose scheduling signals are, respectively, intake and offtake pressures. Running the two detectors simultaneously allows for leakage location. First, the pipeline is identified from operational data, supplied by REN-Gaso...

The internal leakage has a great effect on the performance of a rotary compressor. In this paper a leakage model as a part of a complete simulation model is developed. The leakage model analyzes the oil/refrigerant mixture leakage flow through the roller radial clearance caused by the motion of roller relative to cylinder wall and the pressure difference and considers the effect of the motion o...
