Patent number: 10659328Abstract: A packet of data and a packet-identification value are transmitted to a network device having an identifier. The stored packet-identification value and the identifier are recorded. The stored packet-identification value is then increased and the process repeats. To receive data, an expected identification value is stored in association with the identifier. A packet and a packet-identification value are received from the network device. The identifier and an indication of receipt are stored. If the received value does not match the expected value for the identifier, the received value is stored. If the values match, the stored packet-identification value and identifier are recorded. If the received value exceeds the expected value, the stored packet-identification value, the identifier and the received identifier are recorded. Subsequently, the stored expected value is increased. The process repeats. Network devices and systems are described.Type: GrantFiled: March 28, 2019Date of Patent: May 19, 2020Assignee: Purdue Research FoundationInventors: Vinaitheerthan Sundaram, Patrick Eugster, Xiangyu Zhang

Publication number: 20200151518Abstract: A regularized multi-metric active learning (AL) image classification system which includes three main parts. First, a regularized multi-metric learning process is utilized to jointly learn distinct metrics for different types of image features from remotely sensed image data. The regularizer incorporates the unlabeled data based on the neighborhood relationship, which helps avoid overfitting at early stages of AL, when the quantity of training data is particularly small. Then, as AL proceeds, the regularizer is also updated through similarity propagation, thus taking advantage of informative labeled samples. Finally, multiple features are projected into a common feature space, in which a batch-mode AL strategy combining uncertainty and diversity is utilized in conjunction with k-nearest neighbor (kNN) classification to enrich the set of labeled samples.Type: ApplicationFiled: September 17, 2019Publication date: May 14, 2020Applicant: Purdue Research FoundationInventors: Melba Crawford, Zhou Zhang

Patent number: 10634397Abstract: Heat transfer devices and systems are provided for the rapid cooling of pulsed high-powered, high-flux devices using flash boiling. Such devices comprise at least two fluidly connected chambers and a heat exchanger in thermal communication with a heat source. A flash boiling event is actively triggered at a location close to the heat source by rapid depressurization of the chamber containing a multi-phase coolant. This boiling process allows for high heat transfer rates from the heat source into the chambers due to the latent heat of vaporization, which results in the rapid cooling of the heat source. A porous medium may also be positioned within a chamber of the device to enhance boiling nucleation and extended surface heat transfer. Methods of rapidly cooling pulsed heat sources are also provided using the devices and systems hereof.Type: GrantFiled: September 19, 2016Date of Patent: April 28, 2020Assignee: Purdue Research FoundationInventors: Timothy S.
