Abstract: Julia (http://julialang.org) is a modern open-source programming language for technical computing. Its design offers much greater speed and productivity compared to R or Python, as high-performance code does not need to be wrapped in a low-level language like C or Fortran. After almost a decade of active development, Julia reached its first major release, v1.0, in 2018, and is quickly gaining popularity in scientific computing and data science communities. In this workshop, I will present the basic concepts of Julia and show a little comparison between Julia and other languages, such as R, C, and Python.

The IDRE Early Career Researchers group's panel is a discussion on how high-performance computing (HPC) is used across STEM disciplines. It is led by the following new cohort of IDRE fellows (2023-2024) from various disciplines across the UCLA campus.

Robert Fofrich – Institute of the Environment and Sustainability
Fei-man Hsu – Department of Molecular, Cell, and Development Biology
Alec Linot – Mechanical and Aerospace Engineering
Xiao Luo – Department of Computer Science
Namjoon Suh – Department of Statistics and Data Science

In this presentation, we will explore how the HPC can be used to accomplish common DH tasks, such as network and GIS analysis with large data sets which would be computationally difficult or expensive on typical desktop / laptop hardware. We will use least-cost pathing with GDAL, network analysis with Python, and general DH data analysis and visualization with Jupyter Notebooks. This workshop is designed to highlight the usability and accessibility of these common tools in the HPC environment.

Machine learning has undeniably emerged as a crucial element in the field of science and technology in recent years. Consequently, mastering libraries like scikit-learn, pivotal in the arsenal of machine learning tools, is of paramount importance.In this session, we delve into advanced aspects of leveraging the scikit-learn Python library for high-performance machine learning. We will focus on enhancing modeling speed with multicore processors and accelerators, as well as implementing out-of-core learning. This lecture builds upon the foundational concepts covered in the first session. For optimal benefit, attendees should possess practical experience in Python programming and a solid understanding of fundamental machine learning concepts.

The application of machine learning (ML) and high performance computing (HPC) to humanities research holds tremendous potential, but there are significant challenges to developing a community of experts that can work together at this intersection of topic and technique. HPC experts may not have the background necessary to appreciate how their tools can best be brought to bear on the diverse datasets and conceptual approaches of humanities researchers, and humanities researchers may not have the well-honed background in computational and statistical modeling that resides with ML or HPC specialists. We will approach this topic by focusing on a few case studies in the humanities that illustrate how ML and HPC can both be used to powerful effect, whether by streamlining the initial processing of massive data, modeling and visualizing humanities-relevant datasets, or using deep learning frameworks and the speed and power of GPUs to rapidly prototype predictive models.

Scholarship of visual materials requires close looking and comparison across works. Digitization efforts across the world have allowed for many digital facsimiles of these materials to be made available online. For scholarship, digital viewers are extremely valuable to presenting high-resolution imaging, which allows for close examination of materials. Interoperability has become crucial for institutions for contrasting objects from different collections. Increasing stability in digital visual scholarship means working from authority files from museums, libraries, and archives — institutions are committed to long term preservation and standards.

This workshop will introduce participants to Mirador, an “open-source, web based, multi-window image viewing platform with the ability to zoom, display, compare and annotate images from around the world.” Leveraging the International Image Interoperability Framework (IIIF), the Mirador web-viewer allows users to compare and annotate images and documents. Participants will learn how to install a local instance of Mirador, find Mirador-friendly content and resources, make narratives with annotations, and complete side-by-side transcriptions.

All levels are welcome.

Augmented reality (AR) is the layering of computer-generated perceptual information onto real environments. The experience requires a level of interactivity and sensory engagement. AR is being adopted across the fields of architecture and engineering, as well as adopted by artists to make creative connections between our shared reality and that of innumerable virtual worlds.

This workshop will introduce participants to the design and mechanics of augmented reality. We will focus on working with images, bringing digital objects into live environments through the use of the ArtVive app. Attendees will create free Artivive accounts and learn to create an AR animation. No prior technical experience necessary.

3D models can be formed in a number of ways. Two common surveying methods that result in 3D models are photogrammetry and light detection and ranging or lidar for short.

A form of photogrammetry has been around since the beginnings of photography in the mid-19th century. The term usually refers to the method by which 2D images are compared and combined using optics, projective geometry, and computing to produce a 3D model. This method of image overlap to create a dimensional model is applied in many object-oriented disciplines such as archeology, topographic mapping, architecture, engineering, manufacturing, quality control, police investigation, cultural heritage, and geology.

Lidar is a method for measuring distances (ranging) by illuminating the target with laser light and measuring the reflection with a sensor. Differences in laser return times and wavelengths can then be used to make digital 3D representations of the target. While long used in the earth sciences, lidar is becoming increasingly available to all as these sensors are being added to cellular mobile devices, increasing its academic and commercial potential.

In this workshop, participants will learn about the hardware and software required for these methods. We will also cover the workflow that is involved in producing photogrammetric and lidar 3D models. All levels welcome.

The digital realm is becoming an increasingly popular space for creatives. By creatives, I don't just mean artists, but anyone who wants to harness their creativity, skill, and imagination to produce something with a personal touch and flair. From interactivity to detailed design, browser windows can connect with viewers in powerful ways. So how do you start making the computer screen your canvas? It starts with programming.

Programming is writing instructions that computers can understand and execute. For more than fifty years, computer programmers have been writing code and there are now more than 2,500 documented programming languages. So which language do you start with? What are the differences?

In this workshop, you will receive an introduction to the basics of programming. Specifically, we will cover:

-What is programming
-What is processing
-The difference between Low-Level vs High Level programming languages
-The difference between Client Side vs. Service Side Programs
-p5.js, a free and open-source JavaScript library for creative coding, with a focus on making coding accessible and inclusive for artists, designers, educators, and beginners
-How to use the p5.js web editor
-How to create shapes and draw using p5.js

Satellites are circling our planet, allowing us to "sense" things about the Earth. It is the art and science of making measurements using sensors. Remote sensing has thus become a valuable tool in research and applications in a wide range of disciplines, such as engineering, geology, geography, urban planning, public health, archeology, environmental studies, disaster research, forestry, and agriculture.

In this workshop, you will:

- learn the basic principles of remote sensing methods in research
- have a hands-on session on using Jupyter Notebooks to code in Python
- import Landsat imagery using Google Earth Engine's Python library
- conduct a basic NDVI (Normalized Difference Vegetation Index) analysis

Visual interpretations are meaningful ways to determine spatial trends in our data. However, underlying factors—such as inconsistent geographies, scale, data gaps, overlapping data—have the potential to produce incorrect assumptions, as valuable information may be conveniently hidden from the visual output.

One way to address this issue is to amend your visual output with geo-statistical validation. In this workshop, we will use Python to look at one such approach: Spatial Autocorrelation.

As members of an academic community with a myriad of research initiatives, the need to map information, to spatially analyze, to geoprocess, and to visualize space and time is becoming ubiquitous. But how do you get started? The answer to this question largely depends on what you want to map, and how you want to create your map. The what is usually easy. It is driven by your passion to pursue a research question and to have maps assist in the development of an argument. The how is the difficult part. It may depend on what data you have, what tools you have access to, how comfortable you are with software packages, if you are open to write code or use the command line. Often times, your research question lends itself to a spatial argument. However, providing insights to questions using spatial visualization tools is a process that involves any number of factors, including: data acquisition, data cleanup, geo-enabling data, geocoding data, georeferencing data, visualizing spatial data, overlaying other spatial data, conducting spatial analysis and/or geoprocessing, analyzing results, visualizing results, and publishing results.

In the hands-on segment of the workshop, we will be using the following tools to learn how to analyze and map COVID-19 data:

Abstract: DNA methylation is associated with pathogenesis and disease progression. The IMPACC cohort includes hospitalized COVID-19 participants with five respiratory illness trajectory groups (TGs) according to the prognosis during acute infection (first 28 days). We report the longitudinal DNA methylation profiling of PBMC from 75 participants of IMPACC cohort in UCLA and find (1) DNA methylation is associated with respiratory status and days post-admission, (2) T cell depletion and band neutrophil backlog were observed during acute infection, and (3) Baseline DNA methylation profiles bear prediction power of follow-up risk course. The characterized CpG loci function in immune cell differentiation and STAT protein phosphorylation suggests an epigenetic-regulated SARS-CoV-2 pathogenesis.

Are you interested in creating and publishing 3D virtual environments on the Web? Would you like to be able to quickly spatially model multimedia assets? This workshop will introduce you to foundational techniques and resources which will enable you to produce WebXR (eXtended Reality) content.

This spring, Mozilla sunsetted their WebXR platform, Mozilla Hubs, and builder, Spoke. While the company did release the platform as an open-source tool available at the https://hubsfoundation.org/, personal installations locally or on the cloud can present a challenge with the current level of documentation and community support.

This workshop will cover two new and exciting online alternatives to Hubs. Mud Verse (MUD VERSE – MUD Foundation INC / Art + Tech + Community) is supported by “an innovative nonprofit organization dedicated to the exploration of art, technology, and education” and allows for Spoke files to be imported. The platform operates nearly identically to Mozilla Hubs and it is free to register an account. A second option is 8XR – an HTML5 native game engine. As a game engine, published environments can have increased interactivity built-in and added through additional programming.

During the workshop, participants will be shown how to:

- How to find 3D resources to build a project quickly
- Import, augment, and arrange 2D and 3D visual assets
- Integrate text, video, and audio materials into the WebXR platforms
- Publish and share virtual environments
- Learn how to navigate within the published XR spaces and participate interactively with other digital avatars

No prior technical experience necessary. All levels welcome.

Information systems since the advent of the World Wide Web have offered increasingly sophisticated and reliable tools for inquiry and scholarship based upon centuries-old practices of annotation. What are the connections and tensions between visual and verbal media? How do idiosyncratic readerly practices of scribbling in margins of a book translate into W3C standards for networked multimedia scholarly communication, and what impacts will community standards development have upon the future of knowledge production (or your career)?
This workshop will provide a theoretical introduction to the ancient and still evolving social practice of annotation and situate leading ideas in the concrete tools and practices of digital knowledge production. Taking a 3-tiered approach (simple, intermediate, complex), it will present several handy tools for immediate and long-term application.

This workshop is part of the Research Collections and Digital Scholarship series — a collaboration between the Office of Advanced Research Computing (OARC) and the UCLA Digital Library Program.

Most would agree that in terms of creating virtual experiences as part of research, more context is better. Contextual information allows for a bigger picture to be seen and can provide in situ understanding, despite being remote. With the proliferation of 360 cameras, creating immersive virtual tours has become more commonplace. Whether it is to document the layout of a hydroelectric power plant, provide archival information about historical relics, such as the HMAS OVENS submarine, or share information regarding a cultural heritage site, such as Google Arts and Culture’s Street View tours, immersive 360 capture with annotations has become a strong visual research method and product.
In addition, many fields of research look to present information or scenarios and then survey a sample of participants regarding their experience. Interactive surveys or modules can provide valuable research data for any number of disciplines.

In this workshop, participants will be introduced to Adobe Captivate, a software for building e-learning interactives and annotated 360 virtual tours. Focusing on examples that bridge UCAL’s Biomedical Library space and digital collections, participants will learn how to build a virtual tour with 360 images and video. They will also learn how to annotate their tours with collections materials and how to build some of the platforms various interactive activities, which include:

No prior experience with Adobe products will be needed. However, this product is not part of the Adobe Creative Cloud Suite. If participants want to follow along during the workshop, they will need to purchase and download Adobe Captivate before the workshop.

This workshop is part of the Research Collections and Digital Scholarship series — a collaboration between the Office of Advanced Research Computing (OARC) and the UCLA Digital Library Program.

Within the scholarship of teaching and learning, it has been proven time and again that “Assembling and curating specimen collections is a valuable educational exercise that integrates subject-specific skills such as field collection, curation, identification, organization, and interpretation of relationships.” (Lucky et. al 2019) Digital collections increasingly avail students and scholars of primary source research materials that were only accessible previously by exclusive arrangement in person, if at all. Rare and unique items, such as manuscript documents, cultural artifacts, and historical print ephemera, still present methodological challenges for intensive engagement, even when they are readily and openly accessed. In this third workshop of the series, the focus will shift to strategies for the design, development, and implementation of curriculum-based learning activities that engage collections of IIIF (International Image Interoperability Framework) content.

In this workshop, participants will:
- Learn various strategies for learning activity design using curated collections of items
- Create usable sample learning activities in Bruin Learn, using IIIF-based collections content and embedded IIIF-compatible tools

All levels are welcome. This workshop series is a collaboration between the UCLA Digital Library Program and the Office of Advanced Research Computing. Additional leadership provided by UCLA faculty who have been participating in the LMS Design Lab.

Title: Teaching & Research w/ Digital Collections (2): Tools and Practices for Engaging Digital Collections Content

Date: 1/26/22, Time: 1-2:30pm PT

Description:

The active engagement of digital primary source collections content can, and often does, go beyond viewing materials on collections websites. For sustained inquiry, a wide variety of tools and platforms have been developed that support in-depth scholarly analysis of high quality, reliably-hosted image-based digital content and enable the creation of public-facing scholarly work products. This workshop is the second in a series about teaching and research with digital collections, which highlights the affordances of IIIF content (for International Image Interoperability Framework) but it does not require prior knowledge or skills from the first workshop. It will focus upon the “interoperable” use of digital materials outside of their original institutional context, in both lightweight, easy-to-use tools for analysis, presentation and annotation (such as Storiiies, Exhibit.so, Mirador, and MISE), and more robust platforms for digital scholarship, such as Scalar.

In this workshop, participants will learn:
- What are IIIF manifests and image URLs, and how can they be used in IIIF-compatible tools and platforms?
- How to extract details from image-based content
- How to import materials as linked content into various platforms
- How to annotate, caption, and present content in multimedia essays and exhibits

All levels are welcome. This workshop series is a collaboration between the UCLA Digital Library Program and the Office of Advanced Research Computing. Additional leadership provided by UCLA faculty who have been participating in the LMS Design Lab.

Teaching and Research w/ Digital Collections (Part 1): Navigating A World of High-Quality Primary Source Materials
Thursday, Jan 19, 2023 - 1:00pm to 2:30pm
Online and in-person

Scholarship of visual materials often requires close looking and comparison across works. Digitization programs at “GLAM” institutions (Galleries, Libraries, Archives, and Museums) around the world, including the UCLA Library, have resulted in extraordinary collections of digital facsimiles of rare and unique primary source books, documents, artifacts, and ephemera, available online. For scholarship and curricular research assignments, sophisticated digital viewers present high-resolution image-based content, which allows for close and comparative examination of materials. Interoperable content, which follows certain standards of web-delivery, has become crucial for institutions for contrasting objects from different collections. Increasing stability in digital visual scholarship means working from authority files from museums, libraries, and archives — institutions are committed to long term preservation and standards. Finding items of interest, however, can be a challenge, as digital collections are not universally searchable using familiar tools and practices, and they often differ between institutions.

This workshop will introduce participants to International Image Interoperability Framework or IIIF (generally pronounced “triple-eye-eff”), which is a way to standardize the delivery of images and audio/visual files from servers to different environments on the Web. In this first workshop session in a series of three, participants will learn:

- How to locate and use digital collections with IIIF content
- The benefits of IIIF materials for research and teaching
- Image API
-Presentation API

All levels are welcome. This workshop series is a collaboration between the UCLA Digital Library Program and the Office of Advanced Research Computing. Additional leadership provided by UCLA faculty who have been participating in the LMS Design Lab.

Workshop will be held both:

in person at the IDRE Portal (520 Portola Plaza, 5628 Math Sciences Building, Los Angeles, CA 90095)
over Zoom

Recorded: Tuesday, October 25, 2022 - 12:00pm to 2:00pm

Description
Whether it is interviews, documentary coverage, or contextual footage, video has become a common practice within research. This course is designed to help scholars manage and make use of their research video footage. The workshop will discuss various best practices regarding file management, editing platforms, and techniques for putting footage together to meet your research goals. Participants will be introduced to Davinci Resolve to learn the basics of a preliminary editing process with industry standard software. Software alternatives, such as Adobe Premiere and iMovie will be discussed. In addition, related resources will be shared so that participants can continue to progress in the video editing process.

NFTs seem to be everywhere now. NFT stands for non fungible tokens. The creation and exchange of NFTs has been revolutionary in many ways, particularly in terms of arts and services markets. For example, in the art market, NFTs use blockchain technology to allow for the secure transfer and proof that an original piece of digital art has been sold and is now in the possession of the buyer. It also allows for what we in art history may refer to as provenance of an artwork to be more carefully tracked. The benefits of blockchain is that it enables a global secure transfer of private smart contracts between parties that are stored on an open decentralized network. The result has exposed art market sales more openly and shifted the value of digital art drastically.

In this workshop you will learn about rarity, royalties, and crypto wallets. We will look at some examples of the way NFTs are being used in different markets, but will focus most specifically on growing digital art markets. You will also learn how to set up your own crypto wallet, create your own NFT, and begin mining Ethereum, a popular crypto currency, which is used in the buying and selling of many NFT artworks and items.

No prior knowledge or experience required.
