  • Psychiatric disorders represent a complex interaction between psychological, developmental, neurobiological, and genetic factors. This book focuses on the neurobiological elements of psychiatric conditions. In the last 30 years, much has been learned about the neuroanatomic, neurophysiological, neurochemical, and molecular elements that contribute to major psychiatric illnesses such as schizophrenia, drug dependence, anxiety disorders, major depression, bipolar disorder, and dementias.

  • The eight NPN Darlington connected transistors in this family of arrays are ideally suited for interfacing between low logic level digital circuitry (such as TTL, CMOS or PMOS/NMOS) and the higher current/voltage requirements of lamps, relays, printer hammers or other similar loads for a broad range of computer, industrial, and consumer applications. All devices feature open–collector outputs and free wheeling clamp diodes for transient suppression.

  • Today’s control system designers face an ever-increasing “need for speed” and accuracy in their system measurements and computations. New design approaches using microcontrollers and DSP are emerging, and designers must understand these new approaches, the tools available, and how best to apply them. This practical text covers the latest techniques in microcontroller-based control system design, making use of the popular MSP430 microcontroller from Texas Instruments.

  • Temperature measurement and control are vital in many industrial processes. Accurate control of the temperature is essential in nearly all chemical processes. In some applications, an accuracy of around 5-10~ may be acceptable. There are also some industrial applications which require better than 4-1 ~ accuracy.

  • Modern electronic systems are increasingly digital: digital microprocessors, digital logic, digital interfaces. Digital logic is easier to design and understand, and it is much more flexible than the equivalent analog circuitry would be. As an example, imagine trying to implement any kind of sophisticated micro- processor with analog parts. Digital electronics lets the PC on your desk execute different programs at different times, perform complex calculations, and communicate via the World Wide Web....

  • Making microsystems at a scale level of few microns is called micromachining. Micromachining is used to fabricate three-dimensional microstructures. It is the foundation of a technology called Micro-Electro-Mechanical-Systems (MEMS). MEMS usually consist of three major parts: sensors, actuators, and an associate electronic circuitry that acts as the brain and controller of the whole system.

  • The relationship between the manufacturers of electronic components and the assemblers of electronic circuitry resembles that between two different orders of living beings, for example insects and plants: they need one another to be able to exist, and for that reason there are close links between the evolutionary paths of both. The shapes and the dimensions of their bodies, or respectively their functions, must match one another, so that whatever is needed to ensure the survival of either species can be properly performed. Any mistakes or mismatches are punished by extinction....

  • The passive components used in electronic circuits all make use of one or more of the three fundamental phenomena of resistance, capacitance and inductance. Some components depend for their operation on the interaction between one of these electrical properties and a mechanical property, e.g. crystals used as frequency standards, piezo-electric sounders, etc. The following sections look at components particularly in the light of their suitability for use at RFs, and at how they can be inter-connected for various purposes....

  • An ultrawideband (UWB) pentagon shape planar microstrip slot antenna is presented that can find applications in wireless communications. Combination of the pentagon shape slot, feed line and pentagon stub are used to obtain 124% (2.65–11.30 GHz) impedance bandwidth which exceeds the UWB requirement of 110% (3.10–10.60 GHz). A ground plane of 50 mm 80 mm size is used which is similar to wireless cards for several portable wireless communication devices. The proposed antenna covers only the top 20 mm or 25% of the ground plane length, which leaves enough space for the RF circuitry.

  • What is the correct schematic for the pullup circuitry? Assuming the pullup circuitry is designed correctly, what is the logic function implemented this gate? Assuming the pullup circuitry is designed correctly, when the output of the CMOS gate above is a logic "0", in the steady state what would we expect the voltage of the output terminal to be? What would be the voltage if the output were a logic "1"?
