Deadlock Prevention in Process Control Computer System

Deadlock can occur wherever multiple processes interact. System deadlock is a serious problem in a multiprogramming environment. The approaches to this problem can be divided into three categories: (1) prevention, (2) detection and recovery, and (3) avoidance. This paper proposes a variation of the first approach, partially applying ideas developed in the second and third approaches. This is an...

Computer Mediated Organizational Memory for Process Control

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...

On the design of computer support for process control

The paper investigates augmented reality as a perspective on the design of computer support for process control in a distributed environment. Based on empirical studies of work in a wastewater treatment plant, three technical approaches on augmented reality — augmenting the user; the object of work; and the environment — are examined in terms of a collection of design scenarios .We conclude tha...

Integrating Computer, Control and Communication (C) in Mechatronic Design Process

Mechatronic system design has received considerable attention over the past decade. This trend has been further accelerated by the rapid advancement of computer, communication, and control (C) technologies and the need for technology integration in modern manufacturing, which depends on the harmonious blending of many different technologies. In helping to prepare our future mechanical engineers...
