Abstract

For each of a number of workloads, time intervals within execution performance information that was collected during execution of the workload on a first hardware platform are correlated with corresponding time intervals within execution performance information that was collected during execution of the workload on a second hardware platform. For a workload, the time intervals within the execution performance information on the second hardware platform are correlated to the time intervals within the execution performance information the first hardware platform during which the same parts of the workload were executed. A machine learning model that outputs predicted performance on the second hardware platform relative to known performance on the first hardware platform is trained. The model is trained from the correlated time intervals within the execution performance information for each workload on the hardware platforms.

Abstract

Aspects of the present disclosure are directed to forming a layer of material on a print head. As may be implemented in a manner consistent with examples herein, a layer of material from a transfer film is pressed against a surface of a print head, in which the surface defines fluid nozzle openings that extend from the surface into the print head. Portions of the material pressed onto the surface are therein adhered to the surface and caused to wrap over edges of the surface extending around the openings The transfer film is removed along with a thickness of the material pressed into contact with the surface that remains adhered to the transfer film, as well as some or all of other regions of the material over the openings The remaining layer of the material on the surface is thus formed with a uniform thickness.

A method of digital printing is disclosed in which a digital image to be printed has at least one region having pixels comprising superpositioned layers of a first ink and a second ink. The method includes producing at least one sample print and calibrating misalignment of the superpositioned layers at a plurality of calibration locations on the sample print. The resultant misalignment data is provided to a morphing program to pre-deform the digital image to provide a modified digital image which compensates for misalignment during printing. The image is then printed using the modified digital image. An apparatus and a machine readable storage medium comprising instructions executable by a processor are also disclosed.

The control logic controls the operation of an energy component through the energy component interface and an agent depositing component through the agent depositing component, in forming an output object that is specified in a print job. Additionally, in some examples, the control logic can implement a plurality of modes. Each mode, when selected modulate one or more operational parameters of a least one of the energy component or agent depositing component.

Abstract

Techniques for allocating power budget to a central processing unit (CPU) of a computing device are described. According to an example of the present subject matter, a CPU is operated at default power level corresponding to a thermal design power (TDP) of the computing device. Thereafter, an unused power of the computing device is determined at run-time. The unused power is a difference between an allocated power budget of the component and current power consumption of the component, wherein the allocated power budget is an amount of power allocated to the component based on the TDP of the computing device. Based on the unused power the CPU is operated at a high-performance power level. The high-performance power level is a power level above the default power and up to a maximum power level of the CPU.

Abstract

Aspects are directed to systems in which control node communicates through a peripheral-side wired communications bus for data communications with other bus-coupled nodes. The control node acts as a master with a main-circuit domain during an initialization mode and when the main-circuit domain is deactivated, and acts as a slave, after completion of the initialization mode and when the main-circuit domain is not deactivated. An isolation circuit is used to isolate the main-circuit domain from the control node and, while the main-circuit domain is deactivated, to facilitate communications over the peripheral-side wired communications bus between the control node and another node connected to the peripheral-side wired communications bus.

Abstract

In various examples, a master press and a slave press may be synchronized. A signal associated with the master press printing a first frame on a first web may be received. A point in time may be determined at which the slave press should begin printing, on a second web, a second frame corresponding to the first frame. The determining may be based on the signal associated with the master press and a first distance between the slave press and a downstream location at which the first and second webs converge. The slave press may be operated to begin printing the second frame at the point in time.

A response to the challenge is generated by combining the partial responses from the subset of devices, and is communicated to an authenticator. The user is authenticated when the subset of devices is an authorised subset. Every authorised subset of the set of registered devices comprises at least one device from the first group of devices.

A proximal air flow path from the proximal intake segment to the outlet is shorter than a distal air flow path from the distal intake segment to the outlet. Each of the proximal and distal intake segments comprises a wall segment with at least one hole. An opening ratio of an area of the at least one hole and an area of the respective wall segment is larger in the distal intake segment than in the proximal intake segment.

Abstract

In one example in accordance with the present disclosure, a system is described. The system includes a reader to read an identifier associated with a part. An extractor of the system extracts, based on the identifier, a design file for the part. A modifier of the system receives user input modifying the design file and a transmitter transmits the modified design file for production of the part.

Abstract

An example redundant power supply system comprises a power supply input to receive power from a power supply; a buck-boost converter coupled to the power supply input; and a controller coupled to the buck-boost converter. The controller is to receive a power supply identification signal from the power supply. The controller is also to enable or disable the buck-boost converter based on the power supply identification signal.

Abstract

An example system includes: a landmark detection engine to detect landmark positions of landmarks in images based on facial detection; an optical flow landmark engine to determine the landmark positions in the images based on optical flow of the landmarks between the images; a landmark difference engine to determine, for a landmark in a given image: a distance between a detected landmark position and an optical flow landmark position of the landmark; and a weighted landmark determination engine to determine, for a first and second image, a position for the landmark in the second image based on: a respective detected landmark position and a respective optical flow position of the landmark in the second image; and respective distances, determined with the landmark difference engine, between a first detected landmark position of the landmark in the first image and respective optical flow landmark positions for the first and second images.

Abstract

According to examples, an apparatus may include a fluidic chamber, in which fluid is to be temporarily held. The apparatus may also include a heating component to generate heat to form a drive bubble in the fluid held in the fluidic chamber and a cavitation plate may be provided between the fluidic chamber and the heating component. The cavitation plate may be in communication with the fluidic chamber and may physically separate the fluidic chamber from the heating component to protect the heating component. In addition, a controller may determine a condition in the fluidic chamber based on an electrical signal received from the cavitation plate.
