A Proactive Attack Detection for Heating, Ventilation, and Air Conditioning (HVAC) System Using Explainable Extreme Gradient Boosting Model (XGBoost).

The advent of Industry 4.0 has revolutionized the life enormously. There is a growing trend towards the Internet of Things (IoT), which has made life easier on the one hand and improved services on the other.

Thermal and dynamic mechanical properties of cellulose nanofibers reinforced epoxy composites.

The current study presents about the effect of cellulose nanofibers (CNFs) filler on the thermal and dynamic mechanical analysis (DMA) of epoxy composites as a function of temperature. In this study hand lay-up method was used to fabricate CNF reinforced Epoxy nanocomposites with CNF loading of 0.5%, 0.

Aqua-(2,2'-bipyridine-κN,N')(3,5-dinitro-benzoato-κO)copper(II) tetra-hydro-furan monosolvate.

The title complex, [Cu(C(7)H(3)N(2)O(6))(2)(C(10)H(8)N(2))(H(2)O)]·C(4)H(8)O, features a penta-coordinate Cu(II) atom bound by two monodentate carboxyl-ate ligands, a bidentate 2,2'-bipyridine mol-ecule [dihedral angle between pyridine rings = 5.0 (2)°] and a water mol-ecule. The resulting N(2)O(3) donor set defines a distorted square-pyramidal geometry with the coordinated water mol-ecule in the apical position.

2,4,6,8-Tetra-kis(4-ethyl-phen-yl)-3,7-diaza-bicyclo-[3.3.1]nonan-9-one.

The bicyclo-[3.3.1]nonane ring in the title compound, C(39)H(44)N(2)O, adopts a chair-boat conformation with the four benzene rings being directed away from the carbonyl group.
