May 30, 2020 If you drop a ball from some height, for instance, kinematics predicts where that ball will be T seconds later. But the laws of kinematics break down at the atomic level. The model ceases to be useful. I propose a similar pithy statement for machine learning models No machine learning model is valuable, unless its deployed to production.

Industrial production in Malaysia jumped to a record pace of 50.1 percent year-on-year in April 2021, beating market estimates of a 46.1 percent gain and after a 9.3 percent rise a month earlier. This was the fifth straight month of increase in industrial output, amid a pick-up in economic recovery from the coronavirus pandemic and a low base comparison.
Impact of Covid-19 crisis on industrial production. Industrial production in the EU increased by 0.6 in March 2021 compared with one month before the total production level is now at a level of 99.5 of February 2020, the month immediately before the crisis. Between March 2021 and March 2020, the production of leather and related products ...
The ideal aggregate voids range is the high 30s to low 40s percent. However, voids outside this range can still be used. In some regions, the available coarse aggregate has voids ranging from mid to upper 40s percentage. If the aggregate voids exceed 43, concrete sand can be added to the mix as

coarse aggregate size consisting of ASTM C33 size No. 8 3 8 inch to No. 8, although aggregate sizes No. 7 and No. 67 have been used. This creates a void content in the mixture of 15 to 25. The content of Pervious concreteis another form of no-slump concrete and it
Dec 04, 2017 Aggregate productivity and the rise of mark-ups. Mounting evidence suggests that average mark-ups in the US economy have been increasing. This column argues that about half of measured aggregate productivity growth over the last 20 years can be accounted for by firms with higher mark-ups increasing their relative size.
Nov 01, 2002 The key to eliminating cement balling is keeping the cement from contacting the mix water directly in the drum. Cement has a high affinity for water. So upon contact with water, the dry cement powder acts like a sponge and globs up. The balls form
May 05, 2019 I. Choose a location of concrete batching plant Choosing a appropriate location of the concrete batching is critical, cause it not only affects the construction progress, but affects the quality and cost of the construction. In order to reduce the cost and facilitate the construction, the concrete batching plant should be built in a place that owns a convenient traffic.
specialty mixers or extended mixing times to ensure production of a homogenous fresh mixture. The sequencing of the components introduced into the mixer also influences the homogeneity of the fresh mixture. The high steel fiber content of UHPC can cause a high tendency for fiber balling, which can be more pronounced in large-scale production ...
Segregation of concrete is the separation of cement paste and aggregates of concrete from each other during handling and placement. Segregation also occurs due to over-vibration or compaction of concrete, in which cement paste comes to the top and aggregates settles at the bottom. Segregation of concrete affects strength and durability in ...
5 of the production capacities of conventional crushed stone plants. Two alternative processing systems for pulverized minerals are summarized in Figure 11-19.2-2. In dry processing systems, the mineral aggregate material from conventional crushing and screening operations is subject to coarse and fine grinding primarily in roller mills andor ...
Jul 01, 2019 In the production of concrete, aggregate makes up about 70 of what is added into the cement mix. Traditionally natural sand has been used to make up the aggregate in cement, but it is dredged up from riverbeds, which can be damaging to the environment Takahashi and Yabuta, 2002. In the 1980s scientists began to consider recycling waste ...
