Compressor Handbook: Principles and Practice

Compressor Handbook: Principles and Practice

This book examines the full spectrum of compressor types how they operate how to control them and how operating conditions can significantly impact their performance. Discussed in detail are the influence of pressure temperature molecular weight specific heat ratio compression ratio speed vane position and volume bottles. The various methods of throughput control are also addressed including discharge throttling suction throttling guide pain positioning volume bottles suction valve unloaders speed control as well as how each of these control methods affects compressor life. Compressor surge is defined and discussed in detail along with the types of instrumentation (controllers valves pressure and temperature transmitters) available and which of those are most suitable for controlling search. Case studies have been included to illustrate the principles covered in the text. This edition also includes detailed information on compressor seals. Various types of seals providing the best results for different applications are discussed thereby giving the reader a basic understanding of seals serotypes and applications. | Compressor Handbook: Principles and Practice

Serial Communication Protocols and Standards

Serial Communication Protocols and Standards

Data communication standards are comprised of two components: The “protocol” and “Signal/data/port specifications for the devices involved”. The protocol describes the format of the message and the meaning of each part of the message. To connect any device to the bus an external device must be used as an interface which will put the message in a form which fulfills all the electrical specifications of the port. These specifications are called the “Standard”. The most famous such serial communication standard is the RS-232. In IT technology Communication can be serial or parallel. Serial communication is used for transmitting data over long distances. It is much cheaper to run the single core cable needed for serial communication over a long distance than the multicore cables that would be needed for parallel communication. It is the same in wireless communication: Serial communication needs one channel while parallel needs multichannel. Serial Communication can also be classified in many other ways for example synchronous and asynchronous; it can also be classified as simplex duplex and half duplex. Because of the wide spread of serial communication from home automation to sensor and controller networks there is a need for a very large number of serial communication standards and protocols. These have been developed over recent decades and range from the simple to the highly complicated. This large number of protocols was necessary to guarantee the optimum performance for the targeted applications. It is important for communication engineers to have enough knowledge to match the right protocol and standard with the right application. The main aim of this book is to provide the reader with that knowledgeThe book also provides the reader with detailed information about:- Serial Communication- Universal Asynchronous Receiver Transmitter (UART)- Universal Synchronous/Asynchronous Receiver Transmitter (USART - Serial Peripheral Interface (SPI) - eSPI- Universal Serial Bus (USB)- Wi-Fi- WiMax- InsteonThe details of each technology including specification operation security related matters and many other topics are covered. The book allocates three chapters to the main communication standards. These chapters cover everything related to the most famous standard RS-232 and all its variants. Other protocols such as: I2C CAN ZigBee Z-Wave Bluetooth and others are the subject of the authors separate book “Microcontroller and Smart Home Networks”. | Serial Communication Protocols and Standards

A Holter for Parkinson’s Disease Motor Symptoms: STAT-On

A Holter for Parkinson’s Disease Motor Symptoms: STAT-On

A new information and communication technology (ICT) has been deployed in the battle against Parkinson’s disease a neurodegenerative disorder that is both progressive and disabling with significant impact on quality of life. This book explains the experience following from the achieved results in the REMPARK project on Parkinson’s disease management up to the launch of a new medical product to the European market STAT-ON™. The new medical device STAT-ON™ is a real Holter for the motor symptoms associated to PD. It provides objective information about the severity and distribution of PD motor symptoms and their fluctuations in daily life allowing for an unbiased and correct monitoring of the patient. This real-time remote monitoring solution gives additional information to neurologists opening up new possibilities for more effective treatment more accurate control in clinical trials and for early detection of motor complications. The number of PD patients is continuously rising adding complexity especially in the management at the level of public health. It is an incurable disease with a symptomatic treatment that tries to alleviate the associated symptoms through a correct adjustment of the medication. For this reason it is also very important to be aware of changes in the manifestation of the symptoms which may indicate the need for an adjustment or even a change in the therapy strategy. The intensive complementary use of STAT-ON™ by neurologists health professionals and researchers will increase the independence and quality of life of patients improving their disease management and contributing to a deeper understanding of the nature of the disease.
