Foundations of Industrial Automation and Control (Part I) provides a comprehensive introduction to industrial automation, covering essential components such as sensors, actuators, relays, and control devices. It explains fixed, programmable, and flexible automation, highlighting their principles, applications, and benefits in modern industry. The book also discusses key control systems, including PLC (Programmable Logic Controllers), SCADA (Supervisory Control and Data Acquisition), and magnetic control systems, emphasizing their role in monitoring, controlling, and optimizing industrial processes. Through real-time examples, diagrams, and flowcharts, readers gain practical insights into system design, operation, troubleshooting, and performance enhancement. Designed for diploma and undergraduate students, this volume bridges theoretical knowledge with hands-on practice, preparing learners for advanced studies and real-world industrial challenges.

3-phase core type transformers are one of most important equipment and are mostly used as power transformers in various applications. These transformers are equipped with a third winding for supplying station auxiliaries and for other reasons which is called tertiary winding. The cost of these transformer is a sizable proportion of the total system cost within which it is operated. A number of methodologies have already been developed to execute design of the transformer cost optimally. However, a developed a simplified method for optimizing the design process is depicted in this book in presence of constraints specified by the customer and the regulatory authorities, through exhaustive search using nested loops. The method appears to be best at present considering the enormous speed of the computers. A case study is given in this book based on this method and has been given at the end. Optimal design of 3-phase 3-winding transformers have been made by using two methods and the cost of production has been taken as the objective function based on the two key variables. Exhaustive search and sequential gradient search are used to reach the goal.

Hypertension is another name for high blood pressure. It can lead to severe complications and increases the risk of heart disease, stroke, and death. Blood pressure is the force exerted by the blood against the walls of the blood vessels. Presented as a collection of carefully selected, recent articles from authoritative, well-known journals, this book provides cardiologists and trainees with the latest knowledge and developments relating to hypertension and its management. Divided into seven sections, the text begins with discussion on blood pressure measurement, diet and lifestyle, and epidemiology. The following sections cover hypertension in women specifically, therapeutics, and pathophysiology, concluding with commentary on hypertension control.
