Abstract: Provided is a Charpy impact specimen notch inspector and a use method thereof. The Charpy impact specimen notch inspector includes an inspection table, where a specimen auto-alignment mechanism is provided on a top of the inspection table; a support rod is fixedly connected to a rear side of the top of the inspection table; a host is fixedly connected to a front side of the support rod; and a switch button and a universal serial bus (USB) interface are provided at a left side of the host. This application can automatically recognize and align the position of the to-be-inspected Charpy impact specimen, without adjusting the Charpy impact specimen back and forth, thereby improving the inspection efficiency. Moreover, this application can directly compare the notch picture of the Charpy impact specimen with the corresponding standard model based on the residual neural network in inspection to determine whether the notch is qualified.

Abstract: Techniques for processing a service request are disclosed. An example method includes receiving, from a client device, a request specifying a service that consumes a resource. The method includes generating, by a neural network and without using a forecast for future utilization of the resource, a response to the request. The response includes a prediction of an opportunity cost of consumption of the resource. Generating the response is based on a remaining capacity of the resource and a remaining time to expiration of the resource. The method also includes providing, to the client device, an access to the service based on the response.

Abstract: Techniques for training a prediction model are disclosed. An example method includes processing historical event data comprising a plurality of computer-readable events for a resource to determine previous parameters for the resource. The method also includes generating training data for training the prediction model without using a forecast for future utilization of the resource. The training data comprises a set of proxies generated from previous parameters for the resource. Each proxy is associated with a remaining capacity of the resource and a remaining time to expiration of the resource. The method also includes training the prediction model to generate a mapping from the remaining capacity of the resource and the remaining time to expiration of the resource to the proxy. The method also includes receiving a request that describes a potential future event pertaining to the resource and generating a prediction for the potential future event using the prediction model.

Abstract: Computing devices having slots and components for receipt of different types of peripherals are disclosed. According to an aspect, a computing device includes a body that defines an interior and comprises a rear wall defining a slot that extends into the interior. The slot is sized and shaped for receipt of two or more different types of peripherals. The computing device includes a motherboard that defines another slot being sized and shaped for receipt of the different types of peripherals. The other slot is substantially coplanar with the second slot. The computing device includes a connector operably interfaced with the motherboard and configured to interface with the different types of peripherals.

Abstract: A computing system includes a low-profile chassis a motherboard disposed therein and at least one full-size circuit board coupled to the motherboard within the chassis. A method and another computing system are disclosed.

Abstract: An IT chassis, configured to house IT componentry, includes a forward portion having a forward portion width and a rearward portion having a rearward portion width that is narrower than the forward portion width. A first side of the rearward portion is configured to engage a first slide assembly having a first slide width. A second side of the rearward portion is configured to engage a second slide assembly having a second slide width. The sum of the rearward portion width, the first slide width and the second slide width is substantially equal to the forward portion width.
