A method, system and computer-readable media that enable the employment of an intrusion detection process are provided. This present invention is able to differentiate between certain malicious and benign incidents by means of a two-stage anomaly-based intrusion detection and prevention system. The invented system works at high-speed and with low-memory resources requirements. In particular, the invented method is implemented in a two-stage detector that performs coarse grain detection using sub-profiles 30A-30H (key features extracted from a profile) at one stage and fine grain (detailed behavioral profile) detection at another stage to eliminate unwanted attacks and false positives. Furthermore, in order to suppress specific alarms, the invented system allows the administrator to specify detailed profiles 32A-32H. By using a sub-profile extractor, a sub-profile is extracted, which is then downloaded into the coarse grain detector.

When a transition from a first state where one stage is positioned at a first area directly below projection optical system to which liquid is supplied to a state where the other stage is positioned at the first area, both stages are simultaneously driven while a state where both stages are close together in the X-axis direction is maintained. Therefore, it becomes possible to make a transition from the first state to the second state in a state where liquid is supplied in the space between the projection optical system and the specific stage directly under the projection optical system. Accordingly, the time from the completion of exposure operation on one stage side until the exposure operation begins on the other stage side can be reduced, which allows processing with high throughput. Further, because the liquid can constantly exist on the image plane side of the projection optical system, generation of water marks on optical members of the projection optical system on the image plane side is prevented.

The thermostat may even be used to control a modulated system having more than one stage of cooling or heating.

The Annulus Fibrosus Stent (AFS) is a platform of barriers used in the intervertebral disc. The barrier can be inserted into an intervertebral disc to act to reinforce and / or supplement the disc. The AFS can be inserted at any of the many different stages of disc pathology. The AFS can be inserted to prevent pressure and dissection of disc material which in and of itself can decrease and / or eliminate pain from damaged AF fibers. The AFS can be inserted before disc pathology progresses to a substantial event such as a disc herniation. It can be inserted at any time in the progression of the natural history of disc disease. It can even be inserted when substantially the entire intervertebral disc has been removed. It can be inserted in conjunction with another procedure such as a Nucleus Pulposus Replacement (NPR) or Total Disc Replacement (TDR), etc. The various shapes and material of the AFS in this patent are designed to address particular clinical situations, particular anatomy and particular stages of disc degeneration. The AFS can be inserted directly through the AF, or by a technique of detaching part of the AF with bone without actually cutting a substantial part of AF fibers or layers of fibers or by the Transosseous approach.

An interactive method for radiation treatment planning is disclosed. The method applies to staged treatment planning algorithms, as used, for example, with arc therapy.

A synchronous full bridge rectifier is controlled to provide a power factor near unity. The full bridge rectifiers are transistors each with a controlling input. The AC input signal and currents within the circuit are sensed and sent to a controller. In response, the controller output control signals to turn on / off the rectifying MOSFETS on a timely basis to form a power factor of near one with respect to the AC input signal. The full wave rectifier is made of N-channel MOSFET's, some with fast body diodes. The MOSFET's are rectifiers and PFC control elements. The result is a one stage synchronous rectifier with PFC.

A more efficient multi-stage turbocharging system and method for internal combustion engine systems is set forth. The present invention recovers the loss of a portion of exhaust energy that conventionally occurs in bypassing exhaust flow from one stage to another in a multi-stage turbocharging system. The preferred method of preserving such exhaust energy is through converting a portion of the exhaust energy of the bypassed flow from pressure to kinetic energy (velocity) by passing the bypassed flow through a VGT vane outlet or other variable geometry valve / nozzle, and then not allowing the accelerated flow to dissipate energy before reaching the subsequent stage's turbine wheel, where the accelerated flow may then be converted to a mechanical rotational force by the lower pressure turbine's wheel. Preferred hardware for achieving the object of the invention is also set forth, including a preferred two-volute low pressure turbocharging system with a VGT mechanism in one turbine volute only, or an alternative low pressure turbocharger with two low pressure turbines on a common shaft (again, preferably, with a VGT mechanism in one turbine only).

An optimal thermal seawater desalination process is disclosed, which combines two or more substantially different water pretreatment processes in a unique manner and in a special configuration, hereto unknown to prior desalination arts, to produce a high yield of high quality fresh water, including potable water. In this process a two stage NF membrane pretreatment unit (NF2) with an energy recovery turbo charger (TC) device in between the stages or equipped with an energy recovery pressure exchanger (PX) is synergistically combined with at least one thermal desalination unit to form a dual hybrid of NF2-Thermal (FIG. 4 ), or alternatively the two stage NF2 unit is synergistically combined with a two stage SWRO unit (SWRO2) with an energy recovery TC in between the stages or combined with one stage SWRO (SWRO1) equipped with an energy recovery TC or PX system and the reject from the SWRO2 or SWRO1 unit is made make-up to a thermal unit to form a tri-hybrid of NF2-SWRO2 reject-Thermal (FIG. 5 ). In both the cases of di- or trihybrids the thermal unit is equivalent to a multistage flash distillation (MSFD) or multieffect distillation (MED) or vapor compression distillation (VCD) or thermal reheat (RH) evaporator. Typically a process of this invention using the two stage NF2 initial pretreatment step will perform a semi-desalination step by reducing feed TDS by about 35 to 50%, but most important, especially to the thermal seawater desalination process, it removes the water recovery limiting, scale forming hardness ions of Ca++ and Mg++ by better than 80% and their covalent anions of sulfate to better than 95% and bicarbonate to about 65%. The removal of scale forming hardness ions, especially SO4=, and bicarbonates allowed for the operation of thermal unit in the above hybrids at top brine temperature (TBT) much greater than its present TBT limit by the singular conventional process of 120° C. for MSFD and operation of MED or VCD or RH unit at TBT much higher than their present TBT limit of 65-70° C., with many advantages gained by this process over prior art sweater desalination processes. The process of this invention exceeds all prior thermal seawater desalination arts in efficiency, including water yield, product water recovery ratio and unit water cost as well as in energy consumption per unit product which is equivalent or less than other efficient prior art seawater thermal desalination processes. By this process, an NF product recovery ratio of 75 and 80% or better is achieved from the high salinity Gulf sea (TDS≈45,000 ppm) and about an equal product recovery ratio is also obtained from the SWRO or thermal unit when it is operated on NF product for a total water recovery ratio in excess of 52% for seawater
