The broker accepts communications from publishers and sends them to clients which here is the ESP board. The clients are also known as subscribers. The data subscription in the case of motor speed control is variation in speed data which can be supervised by a suitable sensor. The IoT-based control also requires an end-user control panel as graphical user interface with remote control features. This can be achieved using various open-source software. One such application is Blynk IoT platform that can be installed in any android enabled smartphone. Blynk uses some libraries which can be freely downloaded in the programming environment. Using precise code, the same can be used as a dashboard to connect to the ESP board and control the hardware. This method of control is quite secure and will allow control over only a single dashboard user interface.
Thermal, mechanical, quantum, and analytical sensors

Graphical programs typically consist of an icon diagram including a front panel that serves as the source code for an application program. The front panel provides a graphical user interface for functions to be executed concurrently. The LabVIEW diagram of Figure 1.23 shows a View Image module for generating the data display images shown in Figure 1.22, which may be exported as Matlab files. When this program is initiated, the front panel, enumerated (1), defines display visibility attributes. Assets within a ‘while loop’ are then executed cyclically until control Done is set false, enumerated (2), allowing conditional expressions to break this ‘while loop.’ The metronome icon describes a 50-msec interval within which the ‘while loop’ iterates. The data structure that performs this image generation executes sequentially.
Configuring TCP/IP on a Windows NT Computer

From the Start menu, select Settings>Control Panel. Once the Control panel is displayed, double-click on the Network icon to display the Network dialog box. If the TCP/IP is not installed, one can do so by selecting the Protocols tab in the Network dialog box and then selecting the Add button. Once the TCP/IP protocol suite is added to the computer, the Network dialog box appears similar to the one shown in Exhibit 28.1.

Load to the foundation was applied by a special design loading unit. The loading machine consists of three units: (a) the electrical control panel, (b) hydraulic power pack, and (c) loading device. The loading device is a combination of a beam, four cylinders, four supporting columns, and a base. The hydraulic cylinder is the device that converts fluid energy to linear mechanical force and motion. It converts fluid energy to an output force in a linear direction for executing different jobs. The capacity of the hydraulic cylinder in the universal static loading set- up was 100 kN. The load could be applied to the model foundation in the range of 0–100 kN with an accuracy of 1 N. Forward and backward movement of the cylinder could change the inclination of the load. The inclination of the load remains intact throughout the testing period by the provision of check valve. Dial gauges placed on two sides of the model foundation measured the settlement along the centerline of the model foundation. The arrangement of the test set-up conducted in the laboratory is shown in Figure 4.
Design of an automated particle detection system for Rutherford backscattering (RBS) using LabVIEW

LabVIEW programing is based on the front panel and block diagram windows, which use virtual instruments imitating physical instruments. These subsystems are the most basic and important components of the LabVIEW framework. The block diagram, consisting of input, output, functions, and wires, is a graphical source code that controls individual operations. Basic structures connect multiple functional nodes, which are linked by wires. The front panel is a graphical user interface showing both controls and indicators connected in each block diagram.[20] It combines all of the block diagrams and determines the operational order. Using the front panel, variables are controlled or set as inputs, and the results are displayed simultaneously.

An experimental arrangement was made with the required apparatus to evaluate the DI diesel engine parameters such as performance, combustion, and emission at different operating conditions. The test engine was a direct injection, monocylinder, and water-cooled engine. Figure 4 shows the experimental setup. The experimental methods and selection of instruments to measure various parameters were chosen to minimize the uncertainty of the experimental setup. The exhaust gas is recirculated through a piping system taken from the exhaust pipe. The mass of exhaust gas is governed by means of a control valve. The exhaust gas flow rate is measured using orifice with a manometer. The experiment is carried out to make an analysis of emission and find out the effect on the performance by using EGR, using biodiesel (optimum blend B20), B20TCSAO with MWCNT40ppm, and diesel. For the best blend of B20EESAO with MWCNT30ppm and diesel, an experimental test was carried out with various EGR percentages (5%, 10%, 15%, and 20%). The engine load (20%, 40%, 60%, 80%, and 100%) was applied by eddy current dynamometer at a speed of 1,500rpm. The dynamometer was interfaced with a control panel. The emission parameters such as HC, CO, smoke density, and NOx were measured. All the emissions were sensed by the AVL DI gas analyzer, and AVL smoke meter was used to measure the smoke density. The K-type thermocouple was mounted in the tailpipe of the engine to measure EGT. The combustion parameters such as cylinder pressure and heat release rate were analyzed by an AVL combustion analyzer. The fuel blend was homogeneously mixed for 1 hwith the help of a magnetic stirrer and glass jar. The specification of the engine is listed in Table 3.
