Ceramics are inorganic, non-metallic materials made from a combination of metallic and non-metallic elements. They are frequently silicates, oxides, nitrides or carbides. Ceramics are typically insulative to heat and electricity, and resistant to high temperatures and harsh environments. Ceramic crystal structures are predominantly ionic in nature, with cations and anions arranged in repeating patterns depending on their size and charge. Ceramics exhibit extreme hardness, corrosion resistance, and heat resistance but are also brittle with low ductility. They are classified based on their composition into traditional ceramics, advanced ceramics, oxides, non-oxides, and composites.
Ceramic materials can be classified according to their type, function, or microstructure. They have properties including high strength and stiffness, resistance to heat and corrosion, and hardness. Important ceramic materials include structural ceramics, refractories, abrasives, cements, glasses, advanced ceramics, and magnetic and electronic ceramics.
Composite materials are made from two or more constituent materials that remain separate within the finished structure. They consist of a matrix that supports a reinforcement material, imparting enhanced properties. Common composites include bone, wood, fibers in resin, and carbon fibers in epoxy. Reinforced carbon-carbon is a composite of carbon fibers in a graphite matrix used in spacecraft and missiles due to its strength at high temperatures. Metal matrix composites contain at least two materials, one being a metal matrix with another material such as ceramic or organic reinforcement.
This document provides information about ceramics and pottery materials science. It discusses the classification of solids as crystalline or amorphous and describes properties of materials like mechanical, electrical, thermal and optical properties.

The document also discusses the various stages of clay bodies from greenware to bisque and glaze firing. Different clay types used for pottery like earthenware, kaolin, ball clay and fire clay are described.
Ceramic biomaterials, also called bioceramics, are used to repair or replace damaged bone. They have advantages like high compression strength, wear and corrosion resistance, and the ability to be highly polished. However, they also have disadvantages such as low strength in tension, low fracture toughness, and difficulty in fabrication. The main types are inert ceramics like alumina and zirconia, bioactive ceramics including glass ceramics and bioglass, and biodegradable ceramics like calcium phosphates. Bioceramics are biologically compatible and can enhance healing, but their brittleness limits load-bearing applications. Areas of future research include improving mechanical properties and developing
Alloy steel is steel that contains other alloying elements in addition to carbon. Common alloying elements include manganese, nickel, chromium, molybdenum, vanadium, silicon, and boron. Alloy steel has improved properties over carbon steel such as higher tensile strength, hardness, toughness, wear resistance, creep resistance, and high temperature resistance. These properties make alloy steel suitable for applications in automotive, engineering, construction, agriculture, home goods, and military uses. Production of alloy steel has been increasing to meet the demands of growing industries such as automotive and engineering.

Powder metallurgy is a process that involves producing metal powders and using them to make finished parts. It consists of three main stages: 1) physically powdering the primary material, 2) injecting the powder into a mold or passing it through a die to form a weakly cohesive pre-form, and 3) applying high pressure, temperature, and time to fully form the final part. The process allows for high production rates, low material waste, and flexibility in alloy choices. Parts are made through blending metal powders, compacting them into shapes using dies and presses, and sintering the compacts to strengthen the bonds between particles.

This document summarizes the weldability of nickel and titanium alloys and selection of welding processes. It discusses that nickel alloys like monel and inconel have good weldability by TIG, MIG, and SMAW processes. Preheating is generally not required but post weld heat treatment may be needed. Titanium alloys including pure titanium, alpha, alpha-beta, and beta alloys can be welded by TIG and electron beam processes. Porosity is a major issue in titanium welds due to gas entrapment during solidification. Stress relief heat treatment may be required after welding of some titanium alloys.
Ceramics are nonmetallic materials made by firing clay and other materials like silicates and metal oxides. Ceramics have been made since prehistoric times and the modern ceramics industry produces a wide range of structural materials and products. Key raw materials include clay minerals, feldspar, silica, and refractory materials. The manufacturing process involves preparing and grinding raw materials, shaping, drying, firing, and glazing or other finishing steps.
A composite material is made by combining two or more materials with different properties. The materials do not dissolve into each other but work together to give the composite unique properties. Composites have advantages like higher strength, lower weight, improved stiffness, and better corrosion and fatigue resistance compared to traditional materials. Composites are made of a matrix phase that forms the bulk and a dispersed strengthening phase. Fiber-reinforced composites use a continuous fiber reinforcement for high strength. Common composite materials are used in automobiles, boats, aircraft, electronics, and body armor.

The technology uses reclaimed CO₂ as the dyeing medium in a closed loop process. When pressurized, CO₂ becomes supercritical (SC-CO₂). In this state CO₂ has a very high solvent power, allowing the dye to dissolve easily.
The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

Describing and Interpreting an Immersive Learning Case with the Immersion Cub...Leonel Morgado
Current descriptions of immersive learning cases are often difficult or impossible to compare. This is due to a myriad of different options on what details to include, which aspects are relevant, and on the descriptive approaches employed. Also, these aspects often combine very specific details with more general guidelines or indicate intents and rationales without clarifying their implementation. In this paper we provide a method to describe immersive learning cases that is structured to enable comparisons, yet flexible enough to allow researchers and practitioners to decide which aspects to include. This method leverages a taxonomy that classifies educational aspects at three levels (uses, practices, and strategies) and then utilizes two frameworks, the Immersive Learning Brain and the Immersion Cube, to enable a structured description and interpretation of immersive learning cases. The method is then demonstrated on a published immersive learning case on training for wind turbine maintenance using virtual reality. Applying the method results in a structured artifact, the Immersive Learning Case Sheet, that tags the case with its proximal uses, practices, and strategies, and refines the free text case description to ensure that matching details are included. This contribution is thus a case description method in support of future comparative research of immersive learning cases. We then discuss how the resulting description and interpretation can be leveraged to change immersion learning cases, by enriching them (considering low-effort changes or additions) or innovating (exploring more challenging avenues of transformation). The method holds significant promise to support better-grounded research in immersive learning.

ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.

Authoring a personal GPT for your research and practice: How we created the Q...Leonel Morgado
Thematic analysis in qualitative research is a time-consuming and systematic task, typically done using teams. Team members must ground their activities on common understandings of the major concepts underlying the thematic analysis, and define criteria for its development. However, conceptual misunderstandings, equivocations, and lack of adherence to criteria are challenges to the quality and speed of this process. Given the distributed and uncertain nature of this process, we wondered if the tasks in thematic analysis could be supported by readily available artificial intelligence chatbots. Our early efforts point to potential benefits: not just saving time in the coding process but better adherence to criteria and grounding, by increasing triangulation between humans and artificial intelligence. This tutorial will provide a description and demonstration of the process we followed, as two academic researchers, to develop a custom ChatGPT to assist with qualitative coding in the thematic data analysis process of immersive learning accounts in a survey of the academic literature: QUAL-E Immersive Learning Thematic Analysis Helper. In the hands-on time, participants will try out QUAL-E and develop their ideas for their own qualitative coding ChatGPT. Participants that have the paid ChatGPT Plus subscription can create a draft of their assistants. The organizers will provide course materials and slide deck that participants will be able to utilize to continue development of their custom GPT. The paid subscription to ChatGPT Plus is not required to participate in this workshop, just for trying out personal GPTs during it.
