A Data Compression Method for Wellbore Stability Monitoring Based on Deep Autoencoder

open access: yesSensors
The compression method for wellbore trajectory data is crucial for monitoring wellbore stability. However, classical methods like methods based on Huffman coding, compressed sensing, and Differential Pulse Code Modulation (DPCM) suffer from low real-time

Adaptive residual DPCM for lossless intra coding [PDF]

open access: yesSPIE Proceedings, 2015
In the Differential Pulse-code Modulation (DPCM) image coding, the intensity of a pixel is predicted as a linear combination of a set of surrounding pixels and the prediction error is encoded. In this paper, we propose the adaptive residual DPCM (ARDPCM) for intra lossless coding.

Delta Coding With Dead-Zone Quantization for Bandwidth-Efficient Split Computing on Video Streams

open access: yesIEEE Access
Split computing partitions a deep neural network (DNN) at an intermediate layer, executing the head network on an edge device and transmitting the intermediate feature tensor to a cloud server for tail-network inference.

Connectivity expectations as psychological contract terms in the digital workplace

open access: yesFrontiers in Psychology
IntroductionThe digitalisation of work has normalised expectations of continuous employee availability, yet the relational and contractual implications of these expectations remain insufficiently theorised.
