Cotton-Fiber.pptx
Cotton is a cellulosic plant fiber that is commonly used to make clothing and other textile products. It has been cultivated for over 5,000 years starting in the Middle East and India. China is currently the largest cotton producer, growing 27 million tons annually. The growth cycle of cotton varies by species but involves bolls growing on bushes that contain fibers. Cotton fiber is comfortable, soft, absorbent, color retaining, washable and has good strength when wet, though it wrinkles easily. Over 60% of cotton is used for apparel with the remainder going to home goods and industrial products.
Natural Fibers with Cultivation & Uses
Natural Fibers with Cultivation & Uses (Leaf Fibres, Bast Fibres, Flax, Hemp, Jute, Knaf, Ramie, Sunn or Sunn Hemp, Abroma Augusta, Sisal, Mauritius Hemp, Pineapple Fibre, Caroa Fibre, Abaca or Manila Hemp, Coir or Coconut Fibre, Coco Fibre, Kapok Fibre, Akund Floss)
Fiber or fibres (see spelling differences) are a class of hair-like materials that are continuous "'filaments"' or are in discrete elongated pieces, similar to pieces of thread. They can be used as a component of composite materials. They can also be matted into sheets to make product such as paper or felt. Fibers are of two types: natural fiber, which consists of animal and plant fibers, and man-made fiber, which consists of synthetic fibers and regenerated fibers. The earliest evidence for humans using fibers is the discovery of wool and dyed flax fibers found in a prehistoric cave in the Republic of Georgia that date back to 36,000 BP.

It begins by distinguishing between dyeing and printing, noting that dyeing results in uniform coloration while printing applies color locally in designs. It then covers various printing styles like direct, resist, and discharge printing. The document concludes by describing common printing methods such as block, stencil, roller, screen, and digital printing.
General composition of print paste
The document summarizes the general composition and essential qualities of print pastes used in textile printing. Print pastes typically contain dyestuffs, thickeners, solvents, humectants, oxidizing agents, and defoaming agents. Thickeners are important for ensuring the print paste sinks into the fabric quickly and adheres properly after printing and drying. Other components like hydroscopic agents and pH controllers help facilitate dye fixation during steam treatment. Proper selection and balance of ingredients is necessary for achieving high quality, well-defined prints on fabrics.
Pigment printing
There are key differences between dye and pigment printing. Pigments have no affinity for fibers and are insoluble in water, requiring a binder to fix them onto fibers. Dyes have affinity for fibers and are water soluble. Pigment printing uses a binder that is an aqueous emulsion copolymer which polymerizes during curing to form a strong film embedding the pigment and adhering it to the fiber. Suitable thickeners for pigment printing are emulsion or synthetic thickeners which do not interact negatively with the binder. Emulsion thickeners are prepared using oil, water, emulsifiers and other agents, while synthetic thickeners are high molecular weight copolymers that thicken when

-Hallie Cramer, Google
-Daniel Roesler, UtilityAPI
-Henry Richardson, WattTime
In response to the urgency and scale required to effectively address climate change, open source solutions offer significant potential for driving innovation and progress. Currently, there is a growing demand for standardization and interoperability in energy data and modeling. Open source standards and specifications within the energy sector can also alleviate challenges associated with data fragmentation, transparency, and accessibility. At the same time, it is crucial to consider privacy and security concerns throughout the development of open source platforms.
This webinar will delve into the motivations behind establishing LF Energy’s Carbon Data Specification Consortium. It will provide an overview of the draft specifications and the ongoing progress made by the respective working groups.
Three primary specifications will be discussed:
-Discovery and client registration, emphasizing transparent processes and secure and private access
-Customer data, centering around customer tariffs, bills, energy usage, and full consumption disclosure
-Power systems data, focusing on grid data, inclusive of transmission and distribution networks, generation, intergrid power flows, and market settlement data
From Natural Language to Structured Solr Queries using LLMs
This talk draws on experimentation to enable AI applications with Solr. One important use case is to use AI for better accessibility and discoverability of the data: while User eXperience techniques, lexical search improvements, and data harmonization can take organizations to a good level of accessibility, a structural (or “cognitive” gap) remains between the data user needs and the data producer constraints.
That is where AI – and most importantly, Natural Language Processing and Large Language Model techniques – could make a difference. This natural language, conversational engine could facilitate access and usage of the data leveraging the semantics of any data source.
The objective of the presentation is to propose a technical approach and a way forward to achieve this goal.
The key concept is to enable users to express their search queries in natural language, which the LLM then enriches, interprets, and translates into structured queries based on the Solr index’s metadata.
This approach leverages the LLM’s ability to understand the nuances of natural language and the structure of documents within Apache Solr.
The LLM acts as an intermediary agent, offering a transparent experience to users automatically and potentially uncovering relevant documents that conventional search methods might overlook. The presentation will include the results of this experimental work, lessons learned, best practices, and the scope of future work that should improve the approach and make it production-ready.

Essentials of Automations: Exploring Attributes & Automation Parameters
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
Dandelion Hashtable: beyond billion requests per second on a commodity server
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).
