    Description

    Author: Andrew J. Felton
    Date: 10/29/2024

    This R project contains the primary code and data (following pre-processing in python) used for data production, manipulation, visualization, and analysis, and figure production for the study entitled:

    "Global estimates of the storage and transit time of water through vegetation"

    Please note that 'turnover' and 'transit' are used interchangeably. Also please note that this R project has been updated multiple times as the analysis has updated.

    Data information:

    The data folder contains key data sets used for analysis. In particular:

    "data/turnover_from_python/updated/august_2024_lc/" contains the core datasets used in this study including global arrays summarizing five year (2016-2020) averages of mean (annual) and minimum (monthly) transit time, storage, canopy transpiration, and number of months of data able as both an array (.nc) or data table (.csv). These data were produced in python using the python scripts found in the "supporting_code" folder. The remaining files in the "data" and "data/supporting_data"" folder primarily contain ground-based estimates of storage and transit found in public databases or through a literature search, but have been extensively processed and filtered here. The "supporting_data"" folder also contains annual (2016-2020) MODIS land cover data used in the analysis and contains separate filters containing the original data (.hdf) and then the final process (filtered) data in .nc format. The resulting annual land cover distributions were used in the pre-processing of data in python.

    #Code information

    Python scripts can be found in the "supporting_code" folder.

    Each R script in this project has a role:

    "01_start.R": This script sets the working directory, loads in the tidyverse package (the remaining packages in this project are called using the `::` operator), and can run two other scripts: one that loads the customized functions (02_functions.R) and one for importing and processing the key dataset for this analysis (03_import_data.R).

    "02_functions.R": This script contains custom functions. Load this using the
    `source()` function in the 01_start.R script.

    "03_import_data.R": This script imports and processes the .csv transit data. It joins the mean (annual) transit time data with the minimum (monthly) transit data to generate one dataset for analysis: annual_turnover_2. Load this using the
    `source()` function in the 01_start.R script.

    "04_figures_tables.R": This is the main workhouse for figure/table production and
    supporting analyses. This script generates the key figures and summary statistics
    used in the study that then get saved in the manuscript_figures folder. Note that all
    maps were produced using Python code found in the "supporting_code"" folder.

    "supporting_generate_data.R": This script processes supporting data used in the analysis, primarily the varying ground-based datasets of leaf water content.

    "supporting_process_land_cover.R": This takes annual MODIS land cover distributions and processes them through a multi-step filtering process so that they can be used in preprocessing of datasets in python.

    Description

    This dataset was developed by NREL's distributed energy systems integration group as part of a study on high penetrations of distributed solar PV [1]. It consists of hourly load data in CSV format for use with the PNNL taxonomy of distribution feeders [2]. These feeders were developed in the open source GridLAB-D modelling language [3]. In this dataset each of the load points in the taxonomy feeders is populated with hourly averaged load data from a utility in the feeder’s geographical region, scaled and randomized to emulate real load profiles. For more information on the scaling and randomization process, see [1].

    The taxonomy feeders are statistically representative of the various types of distribution feeders found in five geographical regions of the U.S. Efforts are underway (possibly complete) to translate these feeders into the OpenDSS modelling language.

    This data set consists of one large CSV file for each feeder. Within each CSV, each column represents one load bus on the feeder. The header row lists the name of the load bus. The subsequent 8760 rows represent the loads for each hour of the year. The loads were scaled and randomized using a Python script, so each load series represents only one of many possible randomizations. In the header row, "rl" = residential load and "cl" = commercial load. Commercial loads are followed by a phase letter (A, B, or C). For regions 1-3, the data is from 2009. For regions 4-5, the data is from 2000.

    For use in GridLAB-D, each column will need to be separated into its own CSV file without a header. The load value goes in the second column, and corresponding datetime values go in the first column, as shown in the sample file, sample_individual_load_file.csv. Only the first value in the time column needs to written as an absolute time; subsequent times may be written in relative format (i.e. "+1h", as in the sample). The load should be written in P+Qj format, as seen in the sample CSV, in units of Watts (W) and Volt-amps reactive (VAr). This dataset was derived from metered load data and hence includes only real power; reactive power can be generated by assuming an appropriate power factor. These loads were used with GridLAB-D version 2.2.

    Browse files in this dataset, accessible as individual files and as a single ZIP file. This dataset is approximately 242MB compressed or 475MB uncompressed.

    Description

    Open Context (https://opencontext.org) publishes free and open access research data for archaeology and related disciplines. An open source (but bespoke) Django (Python) application supports these data publishing services. The software repository is here: https://github.com/ekansa/open-context-py

    The Open Context team runs ETL (extract, transform, load) workflows to import data contributed by researchers from various source relational databases and spreadsheets. Open Context uses PostgreSQL (https://www.postgresql.org) relational database to manage these imported data in a graph style schema. The Open Context Python application interacts with the PostgreSQL database via the Django Object-Relational-Model (ORM).

    This database dump includes all published structured data organized used by Open Context (table names that start with 'oc_all_'). The binary media files referenced by these structured data records are stored elsewhere. Binary media files for some projects, still in preparation, are not yet archived with long term digital repositories.

    These data comprehensively reflect the structured data currently published and publicly available on Open Context. Other data (such as user and group information) used to run the Website are not included.

    IMPORTANT

    This database dump contains data from roughly 190+ different projects. Each project dataset has its own metadata and citation expectations. If you use these data, you must cite each data contributor appropriately, not just this Zenodo archived database dump.

    Description

    Database of Uniaxial Cyclic and Tensile Coupon Tests for Structural Metallic Materials

    Background

    This dataset contains data from monotonic and cyclic loading experiments on structural metallic materials. The materials are primarily structural steels and one iron-based shape memory alloy is also included. Summary files are included that provide an overview of the database and data from the individual experiments is also included.

    The files included in the database are outlined below and the format of the files is briefly described. Additional information regarding the formatting can be found through the post-processing library (https://github.com/ahartloper/rlmtp/tree/master/protocols).

    Usage

    • The data is licensed through the Creative Commons Attribution 4.0 International.
    • If you have used our data and are publishing your work, we ask that you please reference both:
      1. this database through its DOI, and
      2. any publication that is associated with the experiments. See the Overall_Summary and Database_References files for the associated publication references.

    Included Files

    • Overall_Summary_2022-08-25_v1-0-0.csv: summarises the specimen information for all experiments in the database.
    • Summarized_Mechanical_Props_Campaign_2022-08-25_v1-0-0.csv: summarises the average initial yield stress and average initial elastic modulus per campaign.
    • Unreduced_Data-#_v1-0-0.zip: contain the original (not downsampled) data
      • Where # is one of: 1, 2, 3, 4, 5, 6. The unreduced data is broken into separate archives because of upload limitations to Zenodo. Together they provide all the experimental data.
      • We recommend you un-zip all the folders and place them in one "Unreduced_Data" directory similar to the "Clean_Data"
      • The experimental data is provided through .csv files for each test that contain the processed data. The experiments are organised by experimental campaign and named by load protocol and specimen. A .pdf file accompanies each test showing the stress-strain graph.
      • There is a "db_tag_clean_data_map.csv" file that is used to map the database summary with the unreduced data.
      • The computed yield stresses and elastic moduli are stored in the "yield_stress" directory.
    • Clean_Data_v1-0-0.zip: contains all the downsampled data
      • The experimental data is provided through .csv files for each test that contain the processed data. The experiments are organised by experimental campaign and named by load protocol and specimen. A .pdf file accompanies each test showing the stress-strain graph.
      • There is a "db_tag_clean_data_map.csv" file that is used to map the database summary with the clean data.
      • The computed yield stresses and elastic moduli are stored in the "yield_stress" directory.
    • Database_References_v1-0-0.bib
      • Contains a bibtex reference for many of the experiments in the database. Corresponds to the "citekey" entry in the summary files.

    File Format: Downsampled Data

    These are the "LP_

    • The header of the first column is empty: the first column corresponds to the index of the sample point in the original (unreduced) data
    • Time[s]: time in seconds since the start of the test
    • e_true: true strain
    • Sigma_true: true stress in MPa

    These data files can be easily loaded using the pandas library in Python through:

    import pandas
    data = pandas.read_csv(data_file, index_col=0)

    The data is formatted so it can be used directly in RESSPyLab (https://github.com/AlbanoCastroSousa/RESSPyLab). Note that the column names "e_true" and "Sigma_true" were kept for backwards compatibility reasons with RESSPyLab.

    File Format: Unreduced Data

    These are the "LP_

    • The first column is the index of each data point
    • S/No: sample number recorded by the DAQ

    Description

    With the ongoing energy transition, power grids are evolving fast. They operate more and more often close to their technical limit, under more and more volatile conditions. Fast, essentially real-time computational approaches to evaluate their operational safety, stability and reliability are therefore highly desirable. Machine Learning methods have been advocated to solve this challenge, however they are heavy consumers of training and testing data, while historical operational data for real-world power grids are hard if not impossible to access.

    This dataset contains long time series for production, consumption, and line flows, amounting to 20 years of data with a time resolution of one hour, for several thousands of loads and several hundreds of generators of various types representing the ultra-high-voltage transmission grid of continental Europe. The synthetic time series have been statistically validated agains real-world data.

    Data generation algorithm

    The algorithm is described in a Nature Scientific Data paper. It relies on the PanTaGruEl model of the European transmission network -- the admittance of its lines as well as the location, type and capacity of its power generators -- and aggregated data gathered from the ENTSO-E transparency platform, such as power consumption aggregated at the national level.

    Network

    The network information is encoded in the file europe_network.json. It is given in PowerModels format, which it itself derived from MatPower and compatible with PandaPower. The network features 7822 power lines and 553 transformers connecting 4097 buses, to which are attached 815 generators of various types.

    Time series

    The time series forming the core of this dataset are given in CSV format. Each CSV file is a table with 8736 rows, one for each hourly time step of a 364-day year. All years are truncated to exactly 52 weeks of 7 days, and start on a Monday (the load profiles are typically different during weekdays and weekends). The number of columns depends on the type of table: there are 4097 columns in load files, 815 for generators, and 8375 for lines (including transformers). Each column is described by a header corresponding to the element identifier in the network file. All values are given in per-unit, both in the model file and in the tables, i.e. they are multiples of a base unit taken to be 100 MW.

    There are 20 tables of each type, labeled with a reference year (2016 to 2020) and an index (1 to 4), zipped into archive files arranged by year. This amount to a total of 20 years of synthetic data. When using loads, generators, and lines profiles together, it is important to use the same label: for instance, the files loads_2020_1.csv, gens_2020_1.csv, and lines_2020_1.csv represent a same year of the dataset, whereas gens_2020_2.csv is unrelated (it actually shares some features, such as nuclear profiles, but it is based on a dispatch with distinct loads).

    Usage

    The time series can be used without a reference to the network file, simply using all or a selection of columns of the CSV files, depending on the needs. We show below how to select series from a particular country, or how to aggregate hourly time steps into days or weeks. These examples use Python and the data analyis library pandas, but other frameworks can be used as well (Matlab, Julia). Since all the yearly time series are periodic, it is always possible to define a coherent time window modulo the length of the series.

    Selecting a particular country

    This example illustrates how to select generation data for Switzerland in Python. This can be done without parsing the network file, but using instead gens_by_country.csv, which contains a list of all generators for any country in the network. We start by importing the pandas library, and read the column of the file corresponding to Switzerland (country code CH):

    import pandas as pd
    CH_gens = pd.read_csv('gens_by_country.csv', usecols=['CH'], dtype=str)

    The object created in this way is Dataframe with some null values (not all countries have the same number of generators). It can be turned into a list with:

    CH_gens_list = CH_gens.dropna().squeeze().to_list()

    Finally, we can import all the time series of Swiss generators from a given data table with

    pd.read_csv('gens_2016_1.csv', usecols=CH_gens_list)

    The same procedure can be applied to loads using the list contained in the file loads_by_country.csv.

    Averaging over time

    This second example shows how to change the time resolution of the series. Suppose that we are interested in all the loads from a given table, which are given by default with a one-hour resolution:

    hourly_loads = pd.read_csv('loads_2018_3.csv')

    To get a daily average of the loads, we can use:

    daily_loads = hourly_loads.groupby([t // 24 for t in range(24 * 364)]).mean()

    This results in series of length 364. To average further over entire weeks and get series of length 52, we use:

    weekly_loads = hourly_loads.groupby([t // (24 * 7) for t in range(24 * 364)]).mean()

    Source code

    The code used to generate the dataset is freely available at https://github.com/GeeeHesso/PowerData. It consists in two packages and several documentation notebooks. The first package, written in Python, provides functions to handle the data and to generate synthetic series based on historical data. The second package, written in Julia, is used to perform the optimal power flow. The documentation in the form of Jupyter notebooks contains numerous examples on how to use both packages. The entire workflow used to create this dataset is also provided, starting from raw ENTSO-E data files and ending with the synthetic dataset given in the repository.

    3D skeletons UP-Fall Dataset

                          Different between Fall and Impact detection 
    

    Overview

    This dataset aims to facilitate research in fall detection, particularly focusing on the precise detection of impact moments within fall events. The 3D skeletons data accuracy and comprehensiveness make it a valuable resource for developing and benchmarking fall detection algorithms. The dataset contains 3D skeletal data extracted from fall events and daily activities of 5 subjects performing fall scenarios

    Data Collection

    The skeletal data was extracted using a pose estimation algorithm, which processes images frames to determine the 3D coordinates of each joint. Sequences with less than 100 frames of extracted data were excluded to ensure the quality and reliability of the dataset. As a result, some subjects may have fewer CSV files.

    CSV Structure

    The data is organized by subjects, and each subject contains CSV files named according to the pattern C1S1A1T1, where:

    C: Camera (1 or 2)

    S: Subject (1 to 5)

    A: Activity (1 to N, representing different activities)

    T: Trial (1 to 3)

    subject1/`: Contains CSV files for Subject 1.

    C1S1A1T1.csv: Data from Camera 1, Activity 1, Trial 1 for Subject 1

    C1S1A2T1.csv: Data from Camera 1, Activity 2, Trial 1 for Subject 1

    C1S1A3T1.csv: Data from Camera 1, Activity 3, Trial 1 for Subject 1

    C2S1A1T1.csv: Data from Camera 2, Activity 1, Trial 1 for Subject 1

    C2S1A2T1.csv: Data from Camera 2, Activity 2, Trial 1 for Subject 1

    C2S1A3T1.csv: Data from Camera 2, Activity 3, Trial 1 for Subject 1

    subject2/`: Contains CSV files for Subject 2.

    C1S2A1T1.csv: Data from Camera 1, Activity 1, Trial 1 for Subject 2

    C1S2A2T1.csv: Data from Camera 1, Activity 2, Trial 1 for Subject 2

    C1S2A3T1.csv: Data from Camera 1, Activity 3, Trial 1 for Subject 2

    C2S2A1T1.csv: Data from Camera 2, Activity 1, Trial 1 for Subject 2

    C2S2A2T1.csv: Data from Camera 2, Activity 2, Trial 1 for Subject 2

    C2S2A3T1.csv: Data from Camera 2, Activity 3, Trial 1 for Subject 2

    subject3/, subject4/, subject5/: Similar structure as above, but may contain fewer CSV files due to the data extraction criteria mentioned above.

    Column Descriptions

    Each CSV file contains the following columns representing different skeletal joints and their respective coordinates in 3D space:

    Description

    The speed, direction of the wind and the variable wind indicator are the variables recorded by the meteorological network of the Chilean Meteorological Directorate (DMC). This collection contains the information stored by 326 stations that have recorded, at some point, the orientation of the wind since 1950, spaced one hour apart. It is important to note that not all stations are currently operational.

    The data is updated directly from the DMC's web services and can be viewed in the Data Series viewer of the Itrend Data Platform.

    In addition, a historical database is provided in .npz* and .mat** format that is updated every 30 days for those stations that are still valid.

    *To load the data correctly in Python it is recommended to use the following code:

    import numpy as np
    
    with np.load(filename, allow_pickle = True) as f:
      data = {}
      for key, value in f.items():
        data[key] = value.item()
    

    **Date data is in datenum format, and to load it correctly in datetime format, it is recommended to use the following command in MATLAB:

    datetime(TS.x , 'ConvertFrom' , 'datenum')

    Example of how to read the metadata and the superclasses: metadata_path = './cifar-100-python/meta' # change this path`\ metadata = unpickle(metadata_path) superclass_dict = dict(list(enumerate(metadata[b'coarse_label_names'])))

    How to load the training and test sets (using superclasses): ``` data_pre_path = './cifar-100-python/' # change this path

    File paths

    data_train_path = data_pre_path + 'train' data_test_path = data_pre_path + 'test'

    Read dictionary

    data_train_dict = unpickle(data_train_path) data_test_dict = unpickle(data_test_path)

    Get data (change the coarse_labels if you want to use the 100 classes)

    data_train = data_train_dict[b'data'] label_train = np.array(data_train_dict[b'coarse_labels']) data_test = data_test_dict[b'data'] label_test = np.array(data_test_dict[b'coarse_labels']) ```

    Downloading the data

    We recommend downloading from Kaggle if you can authenticate through their API. The advantage to Kaggle is that the data is compressed, so it will be faster to download. Links to the data can be found at the top of the readme.

    First, you will need to create an account on kaggle.com. Afterwards, you will need to install the kaggle API: pip install kaggle

    Then, you will need to follow the instructions here to add your username and key. Once that's done, you can run: kaggle datasets download xhlulu/medal-emnlp

    Now, unzip everything and place them inside the data directory: unzip -nq crawl-300d-2M-subword.zip -d data mv data/pretrain_sample/* data/

    Loading FastText Embeddings

    For the LSTM models, we will need to use the fastText embeddings. To do so, first download and extract the weights: wget -nc -P data/ https://dl.fbaipublicfiles.com/fasttext/vectors-english/crawl-300d-2M-subword.zip unzip -nq data/crawl-300d-2M-subword.zip -d data/

    Model Quickstart

    Using Torch Hub

    You can directly load LSTM and LSTM-SA with torch.hub: ```python import torch

    lstm = torch.hub.load("BruceWen120/medal", "lstm") lstm_sa = torch.hub.load("BruceWen120/medal", "lstm_sa") ```

    If you want to use the Electra model, you need to first install transformers: pip install transformers Then, you can load it with torch.hub: python import torch electra = torch.hub.load("BruceWen120/medal", "electra")

    Using Huggingface transformers

    If you are only interested in the pre-trained ELECTRA weights (without the disambiguation head), you can load it directly from the Hugging Face Repository:

    from transformers import AutoModel, AutoTokenizer
    
    model = AutoModel.from_pretrained("xhlu/electra-medal")
    tokenizer = AutoTokenizer.from_pretrained("xhlu/electra-medal")

    Description

    Description

    This dataset contains simultaneous electroencephalography (EEG) and near-infrared spectroscopy (fNIRS) signals recorded from 12 participants while performing a silent naming task and three sensory-based imagery tasks using visual, auditory, and tactile perception. Participants were asked to visualize an object in their minds, imagine the sounds made by the object, and imagine the feeling of touching the object.

    EEG

    EEG data were acquired with a BioSemi ActiveTwo system with 64 electrodes positioned according to the international 10-20 system, plus one electrode on each earlobe as references ('EXG1' channel is the left ear electrode and 'EXG2' channel is the right ear electrode). Additionally, 2 electrodes placed on the left hand measured galvanic skin response ('GSR1' channel) and a respiration belt around the waist measured respiration ('Resp' channel). The sampling rate was 2048 Hz.

    The electrode names were saved in a default BioSemi labeling scheme (A1-A32, B1-B32). See the Biosemi documentation for the corresponding international 10-20 naming scheme (https://www.biosemi.com/pics/cap_64_layout_medium.jpg, https://www.biosemi.com/headcap.htm).

    For convenience, the following ordered channels ['A1', 'A2', 'A3', 'A4', 'A5', 'A6', 'A7', 'A8', 'A9', 'A10', 'A11', 'A12', 'A13', 'A14', 'A15', 'A16', 'A17', 'A18', 'A19', 'A20', 'A21', 'A22', 'A23', 'A24', 'A25', 'A26', 'A27', 'A28', 'A29', 'A30', 'A31', 'A32', 'B1', 'B2', 'B3', 'B4', 'B5', 'B6', 'B7', 'B8', 'B9', 'B10', 'B11', 'B12', 'B13', 'B14', 'B15', 'B16', 'B17', 'B18', 'B19', 'B20', 'B21', 'B22', 'B23', 'B24', 'B25', 'B26', 'B27', 'B28', 'B29', 'B30', 'B31', 'B32'] can thus be renamed to ['Fp1', 'AF7', 'AF3', 'F1', 'F3', 'F5', 'F7', 'FT7', 'FC5', 'FC3', 'FC1', 'C1', 'C3', 'C5', 'T7', 'TP7', 'CP5', 'CP3', 'CP1', 'P1', 'P3', 'P5', 'P7', 'P9', 'PO7', 'PO3', 'O1', 'Iz', 'Oz', 'POz', 'Pz', 'CPz', 'Fpz', 'Fp2', 'AF8', 'AF4', 'AFz', 'Fz', 'F2', 'F4', 'F6', 'F8', 'FT8', 'FC6', 'FC4', 'FC2', 'FCz', 'Cz', 'C2', 'C4', 'C6', 'T8', 'TP8', 'CP6', 'CP4', 'CP2', 'P2', 'P4', 'P6', 'P8', 'P10', 'PO8', 'PO4', 'O2']

    fNIRS

    fNIRS data were acquired with a NIRx NIRScoutXP continuous wave imaging system equipped with 4 light detectors, 8 light emitters (sources), and low-profile fNIRS optodes. Both electrodes and optodes were placed in a NIRx NIRScap for integrated fNIRS-EEG layouts. Two different montages were used: frontal and temporal, see references for more information.

    Stimulus

    Folder 'stimuli' contains all images of the semantic categories of animals and tools presented to participants.

    Example code

    We have prepared example scripts to demonstrate how to load the EEG and fNIRS data into Python using MNE and MNE-BIDS packages. These scripts are located in the 'code' directory.

    Description

    This dataset contains materials from the Coalition for Community-Supported Affordable Geothermal Energy Systems (C2SAGES) project, which evaluated the techno-economic feasibility of a community geothermal system for a residential development in Hinesburg, VT. The dataset includes detailed soil conductivity test reports, energy models, borehole design reports, hourly energy loads for heating, cooling, and hot water, and design layouts. EnergyPlus was used to model building energy loads, and Modelica software was applied for geothermal loop sizing based on these loads and soil conductivity results. Python scripts for network design further refined the models. Key files include PDF reports on borehole design (with projections for 1-year, 15-year, and 30-year systems), soil conductivity test results, EnergyPlus modeling outputs, and 2D/3D design drawings in PDF, DWG, and DXF formats. Python notebooks for network design and OnePipe model files are also provided, with Modelica required for viewing certain files. Outputs and modeling data are in various formats including CSV, JPG, HTML, and IDF, with units and data clearly labeled to support understanding of system design and performance for the proposed geothermal solution.
