Model-driven engineering techniques and tools for machine learning-enabled IoT applications: A scoping review

This paper reviews the literature on model-driven engineering (MDE) tools and languages for the internet of things (IoT). Due to the abundance of big data in the IoT, data analytics and machine learning (DAML) techniques play a key role in providing smart IoT applications. In particular, since a significant portion of the IoT data is sequential time series data, such as sensor data, time series analysis techniques are required. Therefore, IoT modeling languages and tools are expected to support DAML methods, including time series analysis techniques, out of the box. In this paper, we study and classify prior work in the literature through the mentioned lens and following the scoping review approach. Hence, the key underlying research questions are what MDE approaches, tools, and languages have been proposed and which ones have supported DAML techniques at the modeling level and in the scope of smart IoT services.info:eu-repo/semantics/publishedVersio

Structural study of the coordination behavior of a tetradentate NO3-donor amino alcohol ligand toward a CdII:HgII mixture

In this work, the reaction of 2,2′,2″-nitrilotriethanol (NTE) with a 1:1 mixture of CdI2 and HgI2 is investigated. The complex [Cd(NTE)2][Hg2(μ-I)2I4] was synthesized and identified by elemental analysis, FT-IR, 1H NMR spectroscopy and single-crystal X-ray diffraction. The structure of the [HNTE]Cl salt is also presented. In the crystal structure of the complex, the cadmium atom has a CdN2O6 environment in a slightly distorted cube geometry. This geometry is one of the rare cube geometries with a minimum distortion among the Cambridge Structural Database structures for cadmium complexes. The anionic moiety has a binuclear structure with the mercury atoms being in tetrahedral environments. In the network of the complex, in addition to O−H · · · I hydrogen bonds, there are I · · · I interactions which lead to ten-membered rings.Publisher PDFPeer reviewe

2D-coordination polymer containing lead(II) in a hemidirected PbO4S3 environment formed by molecular breaking of the 1,3-oxathiolane ligand

new 1,3-oxathiolane-based ligand, 2-(1,3-oxathiolan-2-yl)pyridine, was prepared and its coordination to lead(II) was investigated. Experiments revealed a ligand-breaking reaction during the complexation process, which leads to the formation of a 2D-coordination polymer of lead(II), [Pb(μ3-HME)(μ-OAc)]n; H2ME: 2-mercaptoethanol. The compounds have been characterized by elemental analysis, FT-IR, 1H NMR spectroscopy and single-crystal X-ray diffraction. X-ray analysis revealed a 2D-coordination polymer extending via acetato bridges. The lead(II) center adopts a rare PbO4S3-distorted pentagonal bipyramidal geometry with a hemidirected arrangement. Upon coordination, the thiol group of the H2ME ligand is deprotonated to coordinate as an anionic ligand. The network extends in sheets in the crystallographic ab plane via Pb–S–Pb and Pb–O–Pb bridges, aided by O–H⋯O hydrogen bonds.Publisher PDFPeer reviewe

The nexus between tax reformation, financial development and economic recovery: The case of Malaysia

The main purpose of this paper is to establish the plausibility and the dynamic nexus between financial developments, economic growth and tax revenue in Malaysia. The analysis of these relationships is vital considering the instability of the global economy which has affected growth. In this study, we employed annual time series data covering the period of 1970–2015. Using advanced co-integration and causality analysis, we found strong evidence on the relationship between each of the examined variables. The results from this study provide evidence on the taxes-growth nexus for Malaysia. An inverted U-shaped relationship is found between financial development and tax collection, while a U-shape reflects the economic condition. The nexus between economic growth and tax revenue enhances fiscal policies in the creation of transparent and mature financial systems which will further boost the collection of government revenues in Malaysia. The results of this study may provide an avenue for researchers and policymakers to understand the nature of the relationship between the examined variables and further assist in the formulation of new policies for economic sustainability

The effect of knowledge management, organizational culture and organizational learning on innovation in automotive industry

The main objective of this study was to examine the direct and indirect effects of organizational culture, knowledge management and organizational learning on innovation. The study combined knowledge-based view theory (KBV), competitive value framework to develop a new original theoretical framework for investigation of factors that affect innovation. Data was gathered from a survey of 279 companies supplying automobile parts to Iran Khodro Company, an Iranian leading automobile manufacturer. Study discovered that organizational culture and knowledge management influenced organizational innovation. Besides that, organizational learning played a significant role as a mediator in that relationship. However, knowledge management was not considered as a mediator in the relationship between organizational culture and organizational innovation. As a practical contribution, the findings of the study serve as a guideline for policy makers and managers in the formulation of policies and strategies for sustainable innovation. Knowing the effectiveness of the innovation can help the government to make decisions about the continuation of this policy. Moreover, study contributes to firm management in formulation of policies and strategies for sustainability in innovation context. Innovation assists organizations supplying the product or service in the automotive sector to operate innovatively, competitively and profitably

Treatment of cadmium(II) and zinc(II) with N2-donor linkages in presence of β-diketone ligand; supported by structural, spectral, theoretical and docking studies

Five compounds, {(μ-OAc)(DPPD)Cd(μ-PYZ)Cd(DPPD)(μ-OAc)}n ( 1 ); HDPPD: 1,3-diphenylpropane-1,3-dione; PYZ: pyrazine, {Cd(μ-4,4'-Bipy)(DPPD)2}n ( 2 ) Bipy: bipyridine [(DPPD)2Zn(μ-4,4'-Bipy)Zn(DPPD)2] ( 3 ), {Cd(μ-DPP)(DPPD)2}n ( 4 ); DPP: 1,3-di(pyridin-4-yl)propane and (Z)-3-hydroxy-1,3-bis(4-methoxyphenyl)prop-2-en-1-one (Z-HMPP), were prepared and identified by elemental analysis, FT-IR, 1H NMR spectroscopy and single-crystal X-ray diffraction. 1 , 2 and 4 form 1D coordination polymers whereas 3 adopts a binuclear structure with the zinc atom in a distorted square-pyramidal geometry. In addition to these complexes, the enolic structure of the Z-HMPP is reported. The ability of compounds to interact with the nine biomacromolecules (BRAF kinase, CatB, DNA gyrase, HDAC7, rHA, RNR, TrxR, TS and Top II) is investigated by the Docking calculations (for 3 and its ligands). The charge distribution pattern of the optimized structure of 3 was studied by NBO analysis. The Polymer Stability Slope for pentameric chain (PSS5, new parameter which is proposed in this paper) of the coordination polymers of 1 , 2 and 4 were calculated to investigate the variation of energy level during the growing the polymeric chain in the solid phase.PostprintPeer reviewe

An ionic Cd/Hg mixed-metal complex with an aminoalcohol ligand

This study was supported financially by the Iran National Science Foundation (INSF).A cadmium-mercury mixed-metal complex of cis-2-((2-((2-hydroxyethyl)amino)ethyl)amino)cyclohexan-1-ol (HEAC), [Cd(HEAC)2][HgI4] (1), was prepared and identified by elemental analysis, FT-IR, 1H NMR spectroscopy, and single-crystal X-ray diffraction. The X-ray analysis revealed an ionic structure for 1 in which the cadmium and mercury atoms have CdN4O2 and HgI4 environments, with distorted octahedral and tetrahedral geometries, respectively. The packing of the components in the crystal of 1 is supported by O-H···I hydrogen bonds, and these interactions lead to the formation of an R44 ${\rm{R}}$ (22) motif.Publisher PDFPeer reviewe
