The impact of the number of high temporal resolution water meters on the determinism of water consumption in a district metered area
DMA zone parameters A diagram of the water consumption in the selected DMA zone is shown in Fig. 3a. Since the selected DMA zone is mainly dominated by multi-family housing, more than 85% of the injected water is taken for the domestic purposes of its residents. About 9% of the water is supplied to a school…

Hierarchical generative modelling for autonomous robots
Here we present the hardware implementation for inverting the implicit hierarchical generative model for autonomous robot control. The specification of the robot platform can be found in Supplementary Table 1. First, we detail the task that is completed autonomously by inverting the generative model, that is, using the model to predict sensor inputs and using…

Subjective data models in bioinformatics and how wet lab and computational biologists conceptualise data
Sample Based on the participant background survey, the majority of participants had postgraduate degrees in biology (doctoral or masters), but computational qualifications ranged from highschool/informal education only to full doctoral degrees. Years of full-time experience in biology ranged from one year to twenty-four years, with nearly half of participants (ten) having between ten to fifteen…

Doubly elastic net regularized online portfolio optimization with transaction costs
Price information We should consider price forecasting method to achieve the data-driven ideology, which can lessen the influence by irrational factors32,33,34 in the market. Specifically, we formulate the expected return by price forecasting method based on historical information. PAMR35 and CWMR12 showed that the predicted relative price in next period is inversely to the current…

Attributed network embedding based on self-attention mechanism for recommendation method
Our model first extracts item attributes and encodes the attribute set of the item into the item preference space. The preference of different users are different points in the item preference space, and users become the anchor vector in the space. In the item preference space, each anchor vector of the user is used to…

Numerical analysis of slip-enhanced flow over a curved surface with magnetized water-based hybrid nanofluid containing gyrotactic microorganisms
Take 2D flow of hybrid nanoliquid comprising of gyrotactic microorganisms on an elongating curved surface using porous media. The nanoparticles of TiO2 and Fe3O4 have dispersed in water for composition of hybrid nanofluid. A curvilinear coordinate system (\(R,S\)) having \(U\) and \(V\) as velocities in \(S -\) and \(R -\) directions are considered. The surface…

Aiding food security and sustainability efforts through graph neural network-based consumer food ingredient detection and substitution
Data The dataset used for this work was purchased from the data company Datafiniti, obtained via queries on their data for food and beverages with ingredients from US retailers (Amazon, Walmart and Target)46. The data acquired was initially noisy and contained errors. The data was sanitised and processed into a more usable form, resulting in…
