Microcontroller Software
Published in Syed R. Rizvi, Microcontroller Programming, 2016
Often referred to as a technical solution, the purpose of design development is to design, develop, and implement solutions to requirements. Design development with respect to HC11 is usually the process of sequencing the operations into an order that will simplify coding, minimize execution time, and conserve storage space. It is not always possible to attain all three objectives. It is frequently necessary to compromise between minimum time and maximum conservation of storage space. However, the most efficient program is the one that solves the problem with the minimum number of instructions and in a minimum amount of time. This requires the designer to come up with design alternatives and choose the best-suited solution for a specific problem. Probably one of the hardest and most discipline-challenging aspects of writing software is to develop alternative solutions. A program flowchart is a useful tool in program organization. It helps to keep the entire program in view and aids in developing the proper sequence of operations.

7B. Process flowchart and process mapping. Some types of processes and structures can be better understood through visualization of flow patterns. A flowchart is a method used to provide a picture of the steps and relationships in a process. This technique would be considered one of the classical diagnostic tools used in areas such as information systems, quality management systems, and employee procedural handbooks. The flowchart can also be used in the measurement phase as a procedural aid, as well as in the analysis phase for identifying improvement potential compared to similar processes. It can be useful in the control phase to aid in describing new processes and would help guide those executing that process.

Flowcharting is a method of graphically describing an existing or proposed process by using simple symbols, lines, and words to pictorially display the sequence of activities. Flowcharts are used to understand, analyze, and communicate the activities that make up major processes throughout an organization. It can be used to graphically display movement of product, communications, and knowledge related to anything, takes an input and adds value to it, and produces an output.

After constructing the graph network for the floorplan, four weighting matrices are applied to it, and finally, the parameterized geometric network model is obtained. By applying the shortest path algorithm, the model provides two outputs: 1) shortest path from each node to the most appropriate exit staircase, 2) the time required to navigate the path based on the length of the path and the speed of movement in proportion to determined LOS. These outputs are related to the ‘base scenario’ and can be implemented to answer questions 1 and 2. To answer the third question and to analyse the bottlenecking effect of different corridor topologies on the evacuation performance in a complex layout, in the subsequent step, all corridor nodes are removed in separate scenarios, and the corresponding ‘bottleneck impact (BI)’ index is calculated for each scenario. The corridor nodes are then ranked based on the resulting BI value, analysing the highest ‘bottleneck impact’ positions. The flowchart in Figure 2 presents the model workflow. This model is scripted as a Python programming code and relies on simple user input to run (Excel file).
Distance-Oriented Cuckoo Search enabled optimal histogram for underwater image enhancement: a novel quality metric analysis
Published in The Imaging Science Journal, 2019
In the proposed underwater image enhancement model, the main objective is to find the optimal histogram limits, since this is the major core of any image quality enhancement. In this work, a new optimization algorithm is proposed, which is the modified form of conventional Cuckoo Search algorithm and it is illustrated in Algorithm. 2. The process of the proposed algorithm is as follows: Initially, it finds the best solution . Then, the evaluation is done by mean absolute difference among the best solution and the remaining solution to attain the distance . The attained distance is as . Then, do the sorting of these distances in ascending order for obtaining the best 10 distance components. Afterward, for the first seven best solutions , apply the Levi Flight update as per Equations (1) and (2). Subsequently for the next three remaining solutions , choose the best solution among values randomly. The flowchart of the proposed Docs algorithm with respect to optimal histogram limits is illustrated in Figure 3.

QT and methods are key to reduce the level of defective items, and thus reducing the overall quality costs contributing to increasing organization’s competitiveness and sustainability (Awaj, Singh, & Amedie, 2013; Ismyrlis & Moschidis, 2015; Tague, 2005). Quality improvement could be done through structured and systematic problem-solving processes (PDCA, DMAIC, Juran Trilogy) where QT can make the process more efficient (Campos, Luz, Rivabem, & Mocelin, 2017). The “seven basic quality control tools” are highlighted by Kaoru Ishikawa for solving the vast majority of problems related to quality in companies: check sheet, Pareto chart, histogram, scatter diagram, flowchart, cause-and-effect diagram and control charts (Ishikawa, 1985). The ability to correctly identify the problem, use the appropriate tools based on the nature of the problem and communicate the solution quickly to others are the key aspects to successful problem resolution (Ishikawa, 1985). These tools are not characterized as complex and they are the easiest to use. Other tools and techniques more complex, like Design of experiments, Quality costing, Quality function deployment, Six Sigma, Benchmarking and Quality circles are also used for manufacturing companies but do not have the same level of use (Fonseca et al., 2015; Lopes, Nunes, Sousa, & Esteves, 2011). However, the use of such methodologies and tools has associated costs (which are part of the manufacturing costs) and different control mechanisms have different associated costs (Germani, Mandolini, & Cicconi, 2011; Peruzzini & Pellicciari, 2017; Xiao et al., 2017).
