Meta is using AI to create low-carbon concrete for its data centres
Facebook's parent company, Meta, has used AI to develop a new way of creating concrete which it claims produces 40 per cent less carbon emissions than standard mixtures, and is already using it in its latest data centre. But experts say that concrete mixtures with similar emissions are already in use across Europe, and that constructing new buildings is incompatible with reducing carbon pollution. Meta is investing heavily in AI research, including building the world's most powerful AI-specific supercomputer. Its main aims are to develop better speech-recognition tools, automatically translate between different languages and help build a 3D virtual metaverse, but the company is also using AI to work on projects such as concrete production. The company says that this construction material is a major contributor to its carbon footprint as it builds data centres around the world for its online services.
Direct 3D Printing of Soft Fluidic Actuators with Graded Porosity
Willemstein, Nick, van der Kooij, Herman, Sadeghi, Ali
New additive manufacturing methods are needed to realize more complex soft robots. One example is soft fluidic robotics, which exploits fluidic power and stiffness gradients. Porous structures are an interesting type for this approach, as they are flexible and allow for fluid transport. Within this work, the Infill-Foam (InFoam) is proposed to print structures with graded porosity by liquid rope coiling (LRC). By exploiting LRC, the InFoam method could exploit the repeatable coiling patterns to print structures. To this end, only the characterization of the relation between nozzle height and coil radius and the extruded length were necessary (at a fixed temperature). Then by adjusting the nozzle height and/or extrusion speed the porosity of the printed structure could be set. The InFoam method was demonstrated by printing porous structures using styrene-ethylene-butylene-styrene (SEBS) with porosities ranging from 46\% to 89\%. In compression tests, the cubes showed large changes in modulus (more than 200 times), density (-89\% compared to bulk), and energy dissipation. The InFoam method combined coiling and normal plotting to realize a large range of porosity gradients. This grading was exploited to realize rectangular structures with varying deformation patterns, which included twisting, contraction, and bending. Furthermore, the InFoam method was shown to be capable of programming the behavior of bending actuators by varying the porosity. Both the output force and stroke showed correlations similar to those of the cubes. Thus, the InFoam method can fabricate and program the mechanical behavior of a soft fluidic (porous) actuator by grading porosity.
Artificial intelligence hiring levels in the mining industry rose in March 2022
The proportion of mining industry operations and technologies companies hiring for artificial intelligence related positions rose in March 2022 compared with the equivalent month last year, with 38.8% of the companies included in our analysis recruiting for at least one such position. This latest figure was higher than the 29.9% of companies who were hiring for artificial intelligence related jobs a year ago but a decrease compared to the figure of 41.4% in February 2022. When it came to the rate of all job openings that were linked to artificial intelligence, related job postings rose in March 2022, with 2% of newly posted job advertisements being linked to the topic. This latest figure was the highest monthly figure recorded in the past year and is an increase compared to the 1.9% of newly advertised jobs that were linked to artificial intelligence in the equivalent month a year ago. Artificial intelligence is one of the topics that GlobalData, from whom our data for this article is taken, have identified as being a key disruptive force facing companies in the coming years.
Viko 2.0: A Hierarchical Gecko-inspired Adhesive Gripper with Visuotactile Sensor
Pang, Chohei, Wang, Qicheng, Mak, Kinwing, Yu, Hongyu, Wang, Michael Yu
Robotic grippers with visuotactile sensors have access to rich tactile information for grasping tasks but encounter difficulty in partially encompassing large objects with sufficient grip force. While hierarchical gecko-inspired adhesives are a potential technique for bridging performance gaps, they require a large contact area for efficient usage. In this work, we present a new version of an adaptive gecko gripper called Viko 2.0 that effectively combines the advantage of adhesives and visuotactile sensors. Compared with a non-hierarchical structure, a hierarchical structure with a multimaterial design achieves approximately a 1.5 times increase in normal adhesion and double in contact area. The integrated visuotactile sensor captures a deformation image of the hierarchical structure and provides a real-time measurement of contact area, shear force, and incipient slip detection at 24 Hz. The gripper is implemented on a robotic arm to demonstrate an adaptive grasping pose based on contact area, and grasps objects with a wide range of geometries and textures.
The Future of Work in Developing Nations - IOT Helps Global Manufacturers Break Into Local Markets
Here, Claudia Jarrett, US country manager at automation parts supplier EU Automation, explains how big players can learn from local businesses, using the IoT to their advantage. Harvard Business Review reports that multinational companies are finding it difficult to optimize their products, services and culture to local markets. The article says that big players are finding international growth costly and cumbersome, especially in countries where they don't have staff who are familiar with local cultures and customers or reliable local supply chain partners. Local companies understand the culture, language and compliance issues, of course, which raises the question: is there a better and more cost-effective way for large manufacturers to integrate local businesses and workers into their networks? Let's look at some steps big manufacturers can take, and why the IoT will prove essential. Three quarters of German manufacturers surveyed in Pricewaterhouse Cooper (PwC)'s Digital Factories 2020 report named regionalization as their main driver for investing in digital factories.
Globalisation in Mining from the perspective of an AI agent
PLEASE NOTE: This is the first generated blog and each new run of the code will be different. This should not be taken as the ground truth. The mining industry has been globalised for many years, with companies operating in multiple countries to maximise production and profits. However, this has led to a number of challenges, including the need to operate in different regulatory environments, manage different labour forces, and navigate different tax systems. Additionally, the volatility of commodity prices has also led to challenges for the industry. Despite these challenges, the mining industry remains a key driver of globalisation, and offers a number of opportunities for companies looking to expand into new markets.
Data Mining: Market Basket Analysis with Apriori Algorithm
Some of us go to the grocery with a standard list; while some of us have a hard time sticking to our grocery shopping list, no matter how determined we are. No matter which type of person you are, retailers will always be experts at making various temptations to inflate your budget. Remember the time when you had the "Ohh, I might need this as well." Retailers boost their sales by relying on this one simple intuition. People that buy this will most likely want to buy that as well. People who buy bread will have a higher chance of buying butter together, therefore an experienced assortment manager will definitely know that having a discount on bread pushes the sales on butter as well.
Data Mining with Rattle
Rattle and R deliver a very sophisticated data mining environment. Data Mining with Rattle is a unique course that instructs with respect to both the concepts of data mining, as well as to the "hands-on" use of a popular, contemporary data mining software tool, "Data Miner," also known as the'Rattle' package in R software. Rattle is a popular GUI-based software tool which'fits on top of' R software. The course focuses on life-cycle issues, processes, and tasks related to supporting a'cradle-to-grave' data mining project. These include: data exploration and visualization; testing data for random variable family characteristics and distributional assumptions; transforming data by scale or by data type; performing cluster analyses; creating, analyzing and interpreting association rules; and creating and evaluating predictive models that may utilize: regression; generalized linear modeling (GLMs); decision trees; recursive partitioning; random forests; boosting; and/or support vector machine (SVM) paradigms. It is both a conceptual and a practical course as it teaches and instructs about data mining, and provides ample demonstrations of conducting data mining tasks using the Rattle R package.
