“…Architecture Design and Management Functions. The network management system is designed with the three components of the computing model at the edge in mind, namely, the IoT devices, [4,[16][17][18][19][20] the IoT Gateway, and the cloud Figure 1, and development of the network management system implies the definition of aspects related to the information of the IoT devices to be managed, precisely the attributes. Given that a standard network management architecture had to be chosen, the following three options were considered: The selection of the Internet management model to implement the IoT network management system was based on the simplicity and low memory and resource use of the SNMP protocol, which is one of the main characteristics of IoT devices, as compared to the CMIP protocol used in the OSI and ITU management models.…”

The Internet of Things (IoT) has the potential to transform the public sector by combining the leading technical and business trends of mobility, automation, and data analysis to dramatically alter the way public bodies collect data and information. Embedded sensors, actuators, and other devices that capture and transmit information about network activity in real-time are used in the Internet of Things to connect networks of physical objects. The design of a network management system for an IoT network is presented in this paper, which uses the edge computing model. This design is based on the Internet management model, which uses the SNMP protocol to communicate between managed devices, and a gateway, which uses the SOAP protocol to communicate with a management application. This work allowed for the identification and analysis of the primary network management system initiatives for IoT networks, in which there are four fundamental device management requirements for any deployment of IoT devices: provisioning and authentication, configuration and control, monitoring and diagnostics, and software updates and maintenance.

“…Several methods such as HPLC, electrochemistry [9,10], and spectrophotometry [11,12] are used to determine LD, despite the diversity of techniques used in the determination, but there are many obstacles (Table 1), for example, the chromatography and techniques connected with it are of high cost in terms of materials and tools used, need to experience in the operation system, sample preparation, and specific conditions in separation, and on the other hand, electrochemical methods are quick to accomplish the analysis, but it displays some errors in the analysis unless it provides a special environment such as the need to clean or polish the electrodes. erefore, spectroscopic methods were used for ease, speed, accuracy, and low cost [13][14][15][16][17][18].…”

A novel, accurate, precise, inexpensive, and sensitive spectrophotometric approach is established to assay levodopa (LD) in both bulk drug and its pharmaceutical formulations. The method depends on the reaction of the ternary complex of a mixed-ligand type among LD, nickel(II) (Ni(II)), and 2,3-diaminopyridine (DAP) to form a stable complex of Ni-LD-DAP which is not extractable. The complex showed maximum absorption at 478 nm, with the apparent molar absorptivity of 4.93 × 103 L·mol−1·cm−1 and Sandell’s sensitivity of 0.04 μg·cm−2. Beer’s law is obeyed within the concentration range of 2–58 μg·mL-1, and the regression line equation is as follows: Y = 0.0251X + 0.0045 (R2 = 0.9990; n = 5). The detection limit and quantitation limit are found to be 0.1388 μg·mL−1 and 0.4207 μg·mL−1, respectively. The present study achieved reasonable accuracy (average recovery of 100.17%) and good precision (RSD did not exceed 1.71%). The developed method has been validated according to the current ICH guidelines (2013). The results of pure LD and pharmaceutical preparations using the recommended spectrophotometry are promising.

“…As illustrated in Figure 1, we relaxed more from this ideal spacing to get the most energetically favorable arrangement for Roth, Meta, and para connections. Using the same method as before, we compute T (E) for each relaxed structure given in the figure using the GOLLUM algorithm [29][30][31][32]. We calculated the thermopower S over a wide range of Fermi energies in Table 2 using the equation…”

If high-efficiency organic isotherm models for mobile processors can be found, a variety of energy harvesting devices, such as Peltier coolers composed of flexible and transparent thin-film materials, might be manufactured. The thermoelectric characteristics of three zinc porphyrins (ZnP) were studied. Theoretical analyses of electron transport across a potassium (Zn-Diphenyl porphyrin: Zn-DPP) molecular sandwiched between electrode surface with three distinct connections were investigated. The contribution of this research is to see what happens because once pyridine is added above the surface of the zinc-porphyrin skeleton, the “edge-over-edge” dimer created from stacked formed rings has a high electrical conductance, minimal exciton thermal conductance, and a large thermal diffusivity on the order of 300 V K1. At room temperature, these variables add up to a projected ZT 4 figure of merit, the greatest ZT for a single organic molecule ever seen. The stacked arrangement of the porphyrin rings causes low phonon thermal conductance, which delays phonon transport across the edge-over-edge molecule and increases the Seebeck coefficient, resulting in a higher ZT value.
