Reaction constants and heat release during thermophilic aerobic digestion of typical secondary and mixed sludges were determined. Maximum reaction constant, determined by measuring the amounts of biodegradable volatile suspended solids (bVSS) removed, occurred in the temperature range of 55-60 ºC. Measurement of heat releases were carried out, at the same range, by the aid of a temperature ...

The plastic industry is a very important manufacturing sector and injection molding is a widely used forming method in that industry. The contribution of this work is the development of a strategy to retrofit control of an injection molding machine based on an embedded system microprocessors sensor network on a field programmable gate array (FPGA) device. Six types of embedded processors are in...

In order to communicate with a PLC (Programmable Logic Controller) flexibly and freely, a data communication model based on the PLC's free port is designed. In the structure of the model, a distributed data communication environment is constructed by using Ethernet and serial adapters. In the communication algorithm, a method of queuebuffer for multi-threaded is used to improve the real-time of...

A unique family of high-speed, microprogrammable asyn-chronous controller (MAC) modules is described in this correspondence.Each MAC module consists of two fundamental mode machines thatcommunicate by means of a handshake interface that permits it to bedriven by any programmable logic device including ROM’s. Any statemachine controller design@ with a MAC module will operate ...

A test procedure for testing mainly the boundary scan cells, and testing partially the test access port controller in programmable logic devices, and field programmable gate array devices, is suggested. The test procedure involves; the configuration of programmable logic devices or field programmable gate array device, the application of test vectors, and finally the verification of the respons...

Area optimization is one of the important problems in reconfigurable systems. A Field-programmable gate array (FPGA) based optimised Fuzzy Logic Controller(FLC) has been developed for speed control of DC Motor by exploiting the basic features of Fuzzy logic. The aim of the proposed scheme is to reduce the area, as compared with conventional Fuzzy Logic Controller. The area of a design refers to...

The heart of most machine control applications is an electronic controller such as a programmable automation controller (PAC) or programmable logic controller (PLC) [1]. The controller is used to receive sensor data and to control the machine using analog and digital I/O signals, and mathematical algorithms like PIDs [2]. Traditionally PLCs have been used in machine control and they are program...

We discuss the unique capabilities of programmable logic devices (PLDs) for experimental quantum optics and describe basic procedures of design and implementation. Examples of advanced applications include optical metrology and feedback control of quantum dynamical systems. As a tutorial illustration of the PLD implementation process, a field-programmable gate array controller is used to stabil...
