Automatic Smart Contract Generation for Internet of Media Things
Mohamed Allouche,Mihai Mitrea,Alexandre Moreaux,Sang-Kyun Kim 한국통신학회 2021 ICT Express Vol.7 No.3
Formally known as ISO/IEC 23093, Internet of Media Things (IoMT) is an emerging paradigm ensuring interoperability among media-centric applications and services designed and deployed for the interpretation, representation or analysis of multimedia content collected by media devices such as cameras or microphones. Under this framework, the present paper establishes the proof of concept for the automation of IoMT specified Smart Contract generation. The advanced modus operandi enables media devices and their content to be seamlessly protected against payment counterfeiting, malicious control, access, interception and/or redirection. To this aim, a comprehensive architectural and experimental framework is conceived, designed, and demonstrated. While the methodological approach is blockchain agnostic, the experimental results are obtained on a 3-node, EEA (Enterprise Ethereum Alliance)-compliant private blockchain.

Geopolymer concrete is finding a growing number of niche applications in the field of civil engineering due to its high compressive strength and strength gain rate, retainage of structural properties in elevated temperature environments, chemical stability in highly acidic conditions and environmental benefits. Combining the above mentioned characteristics with induced electrical conductivity, could enable geopolymer cement to serve as a smart and sustainable cementitious material suitable for health monitoring of civil structures. Carbon fibers were added to fresh geopolymer and OPC (ordinary Portland cement) mixes to enhance their electrical conductivities. AC-impedance spectroscopy analysis was performed on the specimens with fiber fraction ranging from 0.008 to 0.8 with respect to the weight of cementitious binder, to measure their electrical resistivity values and to determine the maximum beneficial fiber content required to attain electrical percolation. Experimental observations suggest that CFR-geopolymer cement exhibits superior performance to CFR-OPC in terms of conducting electrical current.

This study was established that after 3 months storage, olive mill waste (OMW) was enriched with hydroxytyrosol (HT) (2,652 mg/L) and contained only phenolic monomers. It also showed that HT supplementation to surviving diabetic rats decreases considerably intestinal maltase, lactase, sucrose, and lipase activities by 49, 31, 42,and 40%, respectively. In addition, HT enhanced the superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPX) activities by 330, 170, and 301%, respectively and reduced gluthation (GSH) level by 79% in pancreas compared to diabetic rats. Moreover, a significant decrease in the thiobarbituric acid reactive substances (TBARs) level and lactate dehydrogenase (LDH) activity in diabetic rats pancreas by 34 and 49%respectively after administration of HT. In addition, HT improved plasma triglyceride and cholesterol levels in diabetic rats by lowering low density lipoprotein (LDL)-cholesterol and triglycerides (TG) by 27 and 53%,respectively and increasing high density lipoprotein (HDL)-cholesterol content by 72%. These properties of HT are interesting regarding its use as therapeutic agent in biotechnological applications, especially in developing anti-diabetic and hypocholesterolemic drugs.
Experimental Evaluation of Deteriorated CMPs Retrofitted by Different Non-invasive Approaches

Corrugated metal pipes (CMPs) deployed across North America are in various states of deteriorations with diminishing structural health that can cause road failure and pose serious threat to public safety. This paper presents an extensive experimental study conducted on deteriorated and retrofitted CMPs, and compares the results with available analytic approach - Modified Iowa equation. Simulated deterioration was performed on the new CMPs using mechanical approach and later, those CMP specimens were retrofitted using four different non-invasive methods. The specimens were tested under five different overburden pressures. Responses of the soil-pipe systems for deteriorated and rehabilitated specimens in terms of surrounding soil pressure and deformations at crown, spring-line, and invert were recorded and compared. It was found that the soil envelops and the CMPs experienced considerable change in pressure and deflections, respectively due to deterioration. However, rehabilitation using all the invasive approaches helped to regain soil pressures and deflections close to the original state, indicating their viability. The measured deflections from experimental studies were also compared with the predicted values obtained from the Modified Iowa equation. Such comparison is of immense importance to establish design guidelines for rehabilitated liner-CMP culvert systems.

The present study revealed that the nutritive value of grape seeds (Vitis vinifera L.) was $383.55{\pm}0.13Kcal/100g$, with magnesium as the most abundant mineral element ($70.44{\pm}0.88 mg/L$). The maximum phenolic ($392.58{\pm}1.70mg\;of\;GAE/g$), flavonoid ($256.16{\pm}1.60mg\;of\;QE/g$), and tannin ($30.95{\pm}0.17mg\;of\;CE/g$) contents were also found in the ethanol, dichloromethane, and hexane extracts, respectively. The major phytochemical compounds in the ethyl acetate extract were identified via gas chromatography-mass spectrometry (GC-MS) analysis. The ethanol extract has the highest antioxidant activity ($IC_{50}=140{\pm}1.20{\mu}g/mL$ for DPPH, $145.28{\pm}0.45mg$ ${\alpha}-tocopherol/g$ for total antioxidant capacity, and $EC_{50}=80{\pm}1.41{\mu}g/mL$ for ferric-reducing power assays). For ${\beta}-carotene$ test, the highest antioxidant activity was obtained in the hexane extract. A satisfactory antimicrobial activity was found against a panel of microorganisms with the ethyl acetate extract as the best antimicrobial agent. Additionally, it was found that the bactericidal concentration required for the grape seed extract to kill Listeria monocytogenes should be less than 12.50 mg/mL (minimum inhibitory concentration=4).

The maximum phenolic (392.58±1.70mg of GAE/g), flavonoid (256.16±1.60 mg of QE/g), and tannin (30.95±0.17mg of CE/g) contents were also found in the ethanol, dichloromethane, and hexane extracts, respectively. The major phytochemical compounds in the ethyl acetate extract were identified via gas chromatography–mass spectrometry (GC–MS) analysis. The ethanol extract has the highest antioxidant activity (IC50=140±1.20 μg/mL for DPPH, 145.28±0.45mg α-tocopherol/g for total antioxidant capacity, and EC50=80±1.41 μg/mL for ferric-reducing power assays). For β-carotene test, the highest antioxidant activity was obtained in the hexane extract. A satisfactory antimicrobial activity was found against a panel of microorganisms with the ethyl acetate extract as the best antimicrobial agent. Additionally, it was found that the bactericidal concentration required for the grape seed extract to kill Listeria monocytogenes should be less than 12.50 mg/mL (minimum inhibitory concentration=4).
