IoT Based Smart Manufacturing system-Case Studies

Manufacturing now a days growing and becoming more complex, automated and computerized. Smart manufacturing is an emerging form of production manufacturing asset of today and in the future with involvement of smart sensors, actuators, communication technology, smart consumer devices like smart phones and tablets and data-intensive modeling. This paper will highlight a review of IoT application in smart manufacturing. Case studies on advanced techniques used in manufacturing industries for different operation such as Monitoring and controlling of smart equipment, IoT based Smart factory connectivity for industries, Hazardous Gas Detection, Electromyogram (EMG) monitoring system, and Tool wears characterization, Defect predictive in a manufacturing system, Machinery Health monitoring are presented

Traditional utilization and phytochemical analysis of medicinal herb Exacum Linn. from central Western Ghats

In the present study, we focused on the traditional utilization and phytochemical screening of Exacum Linn., a traditional medicinal herb in the Western Ghats of Karnataka, India. There are five species of Exacum viz., E. bicolor, E. pedunculatum, E. lawii, E. carniatum and E. pluminum reported from Western Ghats of Karnataka. Exacum species were used to treat fever, dysentery, sore throat in addition to treat cough, body pain and eye diseases. Analysis of methanol and aqueous extracts showed the presence of phytochemicals such as flavonoids, saponins and alkaloids

Phytochemical Analysis, Antifungal and Antioxidant Activity of Leaf and Fruit of Zizyphus xylopyrus (Retz.) Willd. (Rhamnaceae)

In the present study, phytochemical screening, content of total phenolics, antifungal and antioxidant activity of leaf and fruit extract of Zizyphus xylopyrus (Retz.) Willd. (Rhamnaceae) was investigated in vitro. The leaf and fruit extracts were obtained by maceration process using methanol as solvent. The extracts were screened for phytochemicals by standard tests. Flavonoids, saponins, terpenoids, tannins and phenols were found in both extracts. Antifungal activity of extracts was evaluated by poisoned food technique. Leaf extract suppressed the growth of test fungi to high extent when compared to fruit extract. Antioxidant activity was determined by DPPH radical scavenging, ABTS radical scavenging and Ferric reducing assays. Both extracts exhibited radical scavenging and ferric reducing activity in dose dependent manner with marked activity exhibited by leaf extract. Folin-Ciocalteau reagent method was employed to estimate total phenolic content of extracts. Phenolic content was slightly higher in leaf extract. A positive correlation was observed between phenolic content and antioxidant activity. The plant can be used against phytopathogenic fungi and to prevent and control oxidative damage. Further studies are to be carried out to isolate active principles from the plant and to determine their bioactivities
