“…These indices are often used to represent the physiochemical properties of chemical compounds in quantitative structure-property relationships QSPR ( ) and quantitative structureactivity relationships QSAR ( ) research. One might consult references [7][8][9][10][11][12][13][14][15][16] for more information on topological characterization of micro and nanostructures, and topological indices. A topological index based on molecular graph degrees is a collection of indices used to identify and model chemical compound features.…”

Mathematical chemistry is concerned with the use of mathematics to solve the problems in chemistry. A triangular chain graph is a simple graph composed of a series of triangles. This chain is widely used in the formation of triangular cactus, boron clusters, boron triangular nanotubes, and boron nanotubes. In this paper, the first Zagreb connection index, the first modified Zagreb connection index, and the second Zagreb connection index for triangular chain structures are calculated and derived closed formulas for them. Based on the derived formulas and obtained numerical results, the physicochemical properties of these type of structures can easily be investigated.

“…In quantitative structureproperty relation (QSPR) and quantitative structureactivity relation (QSAR) investigations, these indices are frequently employed to represent the physicochemical properties of chemical compounds [5][6][7][8][9][10][11][12][13]. One can consult references [14][15][16][17][18][19][20][21][22][23][24][25][26] for more information on the topological characterization of microstructure and nanostructure and the importance and applicability of the molecular descriptors. Topological indices include eccentric-based, degree-based, and distance-based indices; here, we are concerned about the degree-based topological indices [27][28][29][30].…”

Fuchsine acid is one of the supramolecular dyes used in Masson’s trichrome stain and has enormous applications in histology. It is also used in Van Gieson’s method with picric acid to show red collagen fibers and in Masson’s trichrome to show smooth muscle in contrast to collagen. In addition to these, it has several other important applications in electronic fields and photonic devices as an organic semiconductor. Therefore, it is of utmost importance to investigate and predict the complex molecular topology of fuchsine acid, which serves as a foundation for the link with its physicochemical properties. In this article, the supramolecular sheet of fuchsine acid is modeled topologically based on the edge partition, and closed formulae are derived for some of its important irregular molecular descriptors, with the ultimate object of throwing some light on the effectiveness of the computed molecular descriptors for QSAR and QSPR analyses.

“…As per the literature, ETAs are broadly classified into 2 major types: sonar input systems (laser signal, infrared signals, or supersonic signals) [30,31] and camera input systems (consisting principally of a mini-CCD camera and fuzzy system) [32][33][34][35]. Bat K sonar, sensible cane, smart vision, and guide cane to observe obstacles in front of the person by transmitting and receiving the mirrored wave normally used supersonic sensors or optical maser sensors [36][37][38][39]. In response to detected obstacles to warn the person, it produces either associate audio or vibration.…”

Vision is, no doubt, one of the most important and precious gifts to humans; however, there exists a fraction of visually impaired ones who cannot see properly. These visually impaired disabled people face many challenges in their lives—like performing routine activities, e.g., shopping and walking. Additionally, they also need to travel to known and unknown places for different necessities, and hence, they require an attendant. Most of the time, affording an attendant is not easier and inexpensive, especially when almost 2.5% of the population of Pakistan is visually impaired. There exist some ways of helping these physically impaired people, for example, devices with a navigation system with speech output; however, these are either less accurate, costly, or heavier. Additionally, none of them have shown perfect results in both indoor and outdoor activities. Additionally, the problems become even more severe when the subject/the people are partially deaf as well. In this paper, we present a proof of concept of an embedded prototype which not only navigates but also detects the hurdles and gives alerts—using speech alarm output and/or vibration for the partially deaf—along the way. The designed embedded system includes a cane, a microcontroller, Global System for Mobile Communication (GSM), Global Positioning System (GPS) module, Arduino, a speech output module speaker, Light-Dependent Resistor (LDR), and ultrasonic sensors for hurdle detection with voice and vibrational feedback. Using our developed system, physically impaired people can reach their destination safely and independently.
