Distributed computing system (DCS) performance is enhanced by caching optimizations. The DCS includes nodes with local caches. Resource accessors such as users are clustered based on their similarity, and the clusters are assigned to nodes. Then processing workloads are distributed among the nodes based on the accessors the workloads implicate, and based on which nodes were assigned to those accessors' clusters. Clustering may place security peers together in a cluster, and hence place peers together on a node. Security peers tend to access the same resources, so those resources will more often be locally cached, improving performance. Workloads implicating peers also tend to access the same resources, such as peers' behavior histories, so those resources will likewise tend to be cached locally, thus optimizing performance as compared for example to randomly assigning accessors to nodes without clustering and without regard to security peer groupings.

This disclosure describes a novel methodology for anti-surge and anti-choke control systems protecting centrifugal and axial compressors. The methodology, based on Buckingham's π-theorem for compressors, presents compressor performance maps in dimensionless rectangular π-term coordinates that are independent of compressor inlet conditions, fluid molecular weight and rotational speed. The full range of compressor operating points from surge to choke is monitored and controlled when surge and choke limits are available. This is accomplished by converting rectangular coordinates presented in π-terms to polar coordinates, and then converting them to a controlled variable used in the closed-loop controllers. The methodology provides control algorithms for variable speed compressors, variable geometry compressors equipped with inlet guide vanes or stator vanes that exhibit displacement of surge and choke limits. The methodology most accurately estimates the location of the operating point relative to its limit in polar coordinates if only the surge or choke limit is available. The presented protection methods are applicable to any known types of dynamic compressors for industrial, commercial, jet engines, turbochargers.

This disclosure shows the ability of a readily-available oxidizer to achieve oxidation of 5-amino-1H-tetrazole (5-AT) to 5-nitrotetrazole (5-NT) in high yields in a single pot synthesis. This strategy reduces the synthesis of this important energetic material down to a single step and eliminates highly sensitive diazonium and copper salt primary explosive intermediates. The overall yield of this process is 48-53% and the resultant aqueous solution of product effectively used for the preparation of nitrotetrazole-containing primary explosive DBX-1. Unlike current methods of nitrotetrazole preparation, the novel method is entirely solution-based and prepares a final solution of sodium nitrotetrazolate, never once needing to handle energetic intermediates or products, making it a much safer method of nitrotetrazole preparation.

A bicycle gearshift is operated by imposing on the chain guide a primary displacement in the axial direction with respect to a cogset, to move the chain between the sprockets. Simultaneously with imposing on the primary displacement imposing on the chain guide a secondary displacement in the radial direction with respect to the cogset. The secondary displacement is of a greater size when the primary displacement takes place in the area of the cogset with the larger sprockets whereas it is of a smaller size when the primary displacement takes place in the area of the cogset with the smaller sprockets.

The embodiments herein provide a system and method for controlling an operation of the components in the two/three wheeled vehicle through a smartphone. The system comprises a vehicle module, a smartphone and a cloud computing system. The vehicle module reads the vehicle parameters with a vehicle parameter reader and sensors. The read vehicle parameter are forwarded to the microprocessor for transmission to the smartphone through a transceiver using a wired or wireless network. The microprocessor sends the vehicle parameters data to the smartphone for generating the commands/events for controlling an operation of the parts/components of the vehicle through the vehicle parameter controller. The data is uploaded to a cloud computing system and analyzed using an artificial intelligence module, a machine learning module and a pattern recognition module for providing insights/predictions to the user for controlling the vehicle.

When a diagnostic period of a specific failure arrives, a management center transmits, to a vehicle, an instruction to order execution of a failure diagnosis of the specific failure. When an ECU of the vehicle receives the instruction to order execution of the failure diagnosis from the management center, the ECU of the vehicle determines whether or not the failure diagnosis can be executed. When the failure diagnosis cannot be executed, the ECU causes the vehicle to continue traveling without executing the failure diagnosis, and ends a process. In this case, the ECU postpones the failure diagnosis in the current diagnostic period, and executes the failure diagnosis when a next diagnostic period arrives. When the ECU determines that the failure diagnosis can be executed, the ECU executes the failure diagnosis.

A vehicle includes a powerplant, a front axle having first and second wheels and a differential operably coupled to the powerplant. A power-takeoff unit (PTU) is connected to the differential. A rear axle has third and fourth wheels and a gearbox connected to the PTU without a center differential. The gearbox has a first clutch configured to selectively couple the third wheel to the PTU and a second clutch configured to selectively couple the fourth wheel to the PTU. A controller is programmed to determine, during a turn, which of the third and fourth wheels is an outer rear wheel, determine whether there is a positive or negative torque on the outer rear wheel, and disengage, or keep disengaged, the one of the first and second clutches that is associated with the outer rear wheel in response to a negative torque on the outer rear wheel.

Techniques and methods for providing additional safety for interactions with pedestrians. For instance, a vehicle may identify a region through which the vehicle and agent (such as a pedestrian) pass. The vehicle may then use a first state of the vehicle and predicted positions for the agent to determine a first collision metric between the vehicle and the agent within the region. Additionally, the vehicle may use the first collision metric to determine a maneuver for the vehicle. Next, the vehicle may simulate a state of the vehicle at a second time, where the state if based on the maneuver. The vehicle may then determine a second collision metric between the vehicle and the agent within the region using the state and the predicted positions of the agent. Additionally, the vehicle may use the second collision metric to determine another maneuver for the vehicle.

When a speed difference between a maximum rotation speed and an engine rotation speed, that is, an actual rotation speed difference, is equal to or less than a margin rotation speed difference, an engine operating point is changed such that the actual rotation speed difference becomes greater than the margin rotation speed difference. Accordingly, the speed difference between the maximum rotation speed and the engine rotation speed is prevented from becoming equal to or less than the margin rotation speed difference. As a result, since a relatively sufficient margin is secured in the difference between the maximum rotation speed and the engine rotation speed, it is possible to prevent the engine rotation speed from falling into a high-rotation state in which the engine rotation speed exceeds the maximum rotation speed.
