Abstract: The present disclosure provides a control device for a rotating cylinder that may align horizontality or precisely control a target angle using six obliquely cut wheels, and at the same time, adjust a height and a position of a rotation axis. In an embodiment, the control device for a rotating cylinder includes a first rotary unit including a first wheel and a second wheel; a second rotary unit connected to the first rotary unit and including a third wheel and a fourth wheel; and a third rotary unit including a fifth wheel and a sixth wheel; a driving unit independently driving the first to sixth wheels; a memory storing commands; and a processor rotating at least one wheel among the first to sixth wheels by executing the commands, to control the driving unit such that an inclination angle of the rotating cylinder is adjusted to a preset target value.

Abstract: A data market using federated learning is disclosed. According to an embodiment, an operating method of a central server includes providing data provider information to a consumer, receiving, from the consumer, data request information including an artificial neural network (ANN) model, transmitting the data request information to target data providers, receiving, from the target data providers, a result of training of an individually trained ANN model, generating a common model based on the result of the training, and transmitting the common model to the consumer.

Abstract: A method for detecting a radionuclide using energy spectrum data represented by a count depending on energy obtained from a radiation detector, including: calculating a count ratio for a particular energy value using a background energy spectrum data measured without a target object to detect the radionuclide and a target energy spectrum measured in the presence of the target object; and comparing a background count ratio and a target object count ratio, where the count ratio is a ratio of a low count sum of count values which is an energy value or less divided by a high count sum of the count values which is greater than the particular energy value, or a ratio of the low count sum of the count values which is smaller than the particular energy value divided by the high count sum of the count values which is the particular energy value or greater.

Abstract: Systems, methods, and media for connecting emergency communications are provided.

Abstract: A system includes one or more devices connected to or within one of a group of emergency services networks. The one or more devices may generate a text message that includes information identifying a user device, information identifying a geographic location of the user device, and information identifying a particular emergency services network of the group of emergency services networks; establish, based on the text message, a text-based communication session between the user device and a call taker device within the particular emergency services network; store session information regarding the text-based communication session; receive a subsequent text message; and transmit the subsequent text message to the call taker device based on the session information.
