classifications: a, b, and c products, ranked from most important to least important. since there were two criteria: 1) sales revenue, and 2) picking frequency, it was then necessary to do an abc analysis on each and then combine them which created a double abc analysis. this meant that instead of having three classifications from one abc analysis,,description for 3541: machine tools, metal cutting types,establishments primarily engaged in the manufacture of electric and gas welding and soldering equipment are classified in industry 3548, and those manufacturing portable power-driven handtools are classified in industry 3546. automatic chucking machines. boring
the an/slq-48 detects, locates, classifies, and neutralizes moored mines and mines resting on the seabed. the vehicle uses high-frequency, high-resolution sonar, low light level television (llltv), cable cutters, and explosive charges to detect and dispose of mines, while remaining tethered to the vessel by a 1,070 metres (3,510 ft) cable and under control of the vessel.,tong li (李童) - google scholar,hierarchy construction and classification of heterogeneous information networks based on rsdaef j zhang, z jiang, y du, t li, y wang, x hu data & knowledge engineering 127, 101790 , 2020
solving a simple classification problem with python — fruits lovers’ edition. in this post, we’ll implement several machine learning algorithms in python using scikit-learn, the most popular machine learning tool for python. using a simple dataset for the task of training a classifier to distinguish between different types of fruits.,hazardous area classification for electrical systems,the iec zone classification also differs from north american standards in its grouping of the hazardous gases or vapors as either group i or group ii. group i is for use in describing atmospheres that contain firedamp (a mixture of gases, composed mostly of methane, found underground, usually in mines). group ii covers all other flammable gases.
types of soil excavation tools and machines: now a days, for the soil excavation there are so many equipment’s are there and these are classified into two types. 1. hand tools 2. machineries hand tools for soil excavation: these are generally used for smaller depths of excavations in small areas. man power is required to operate these tools.,mining - dredging | britannica,mining - mining - dredging: dredging is the underwater excavation of a placer deposit by floating equipment. dredging systems are classified as mechanical or hydraulic, depending on the method of material transport. the bucket-ladder, or bucket-line, dredge has been the traditional placer-mining tool, and it is still the most flexible method for dredging under varying conditions.
classification of surveying surveying is classified based on various criteria including the instruments used, purpose, the area surveyed and the method used. classification on the basis of instruments used. based on the instrument used; surveys can be classified into; i) chain tape surveys ii) compass surveys iii) plane table surveys,github - kk7nc/text_classification: text classification,naïve bayes text classification has been used in industry and academia for a long time (introduced by thomas bayes between 1701-1761). however, this technique is being studied since the 1950s for text and document categorization. naive bayes classifier (nbc) is generative model which is widely used in information retrieval.
