David Steel, the author of this perfect, very useful and informative two-volume set, was deservedly considered to be among the world recognized and respected naval publishers who worked in the past, namely in the late XVIII/early XIX centuries. His interesting and well-though publications were focusing on the naval strategy and established ship construction techniques.

The present work by Steel was originally released nearly forty years ago and was treated as the very first English manual providing all interested readers including students and specialists, with the best naval practice. The content of this set was specifically designed and worked out to aspire the young officers. The success of these books resulted in establishing the brilliant reputation of David Steel as a publisher. These publications provide all readers with the good descriptions of both practical and theoretical aspects of the masts/rigging, sails and the whole science of sailing.

The author perfectly combined the practical advice which is supported by both scientific and math explanations with the numerous helpful illustrations providing valuable insight into the British seamanship of the times of the Napoleonic wars. We would recommend these volumes to all persons with the deep interest in naval sciences.

In this release of Electronics for Dummies the text part is supplemented with a huge number of colourful images and detailed diagrams; the publication will provide readers with the very easy-to-follow instructions that will show them how exactly various electronic components function, advice on proper choosing and using of the essential electronic tools, and even some nice projects that the readers can build themselves in less than half-an-hour.

The publication provides necessary information and technical guidance on the circuit basics, including the explanation of the voltage, current flow and power, critical components of the electrical circuit, namely inductors, capacitors, diodes, resistors, etc., versatile chips... The readers will get to know how to perform a correct analysis of the electrical circuit and understand all associated rules governing voltage and current, as well as their proper application.

The safety tips necessary to follow in order to keep yourself safe are also there in the book. In short, this publication is aimed to help interested people in their exploration of the very basics of electronics. You will see how various tiny parts manipulate the electric current, how the transistors switch and amplify it, and get so much more other useful and interesting information.

The approach to probability and statistics used in this chapter is the pragmatic one that probability and statistics are methods of operating in the presence of incomplete knowledge. The most common example is tossing a coin. It will land heads or tails, but the relative frequency is unknown. The two events are often assumed equally likely, but a skilled coin tosser may be able to get heads almost all of the time.

The statistical problem in this case is to determine the relative frequency. Given the relative frequency, probability techniques answer such questions as how long can we expect to wait until three heads appear in a row. Another example is light bulbs. The outcome is known: any bulb will eventually fail. If we had complete knowledge of the local universe, it is conceivable that we might compute the lifetime of any bulb. In reality, the manufacturing variations and future operating conditions for a lightbulb are unknown to us. It may be possible, however, to describe the failure history for the general population. In the absence of any data, we can propose a failure process that is due to the accumulated effect of small events (corrosion, metal evaporation, and cracks) where each of these small events is a random process.

It is shown in the statistics section that a failure process that is the sum of many events is closely approximated by a distribution known as the normal distribution. A manufacturer can try to improve a product by using better materials and requiring closer tolerances in the assembly. If the light bulbs last longer and there are fewer differences between the bulbs, then the failure curve should move to the right and have less dispersion...

Here is the truly must-have reference for any electrical engineer. We would treat this publication as the power system engineering classic. The book was prepared by the professional practicing electrical engineers that were considered the recognized industry experts. This reference book covers all relevant power generation aspects as well as transmission/distribution of the electric power.

This publication starts with the sections describing and discussing the basic characteristics of the power system, such as the overhead lines and cable, reactors, transformers, symmetrical components etc. Then the authors move to the calculations and various applications including regulation of the electric power regulation and possible losses, stability and relaying issues, distribution system, protection from lightning, steady state performance etc.

Though published quite a long time ago, the book remains very actual since the basic design and equipment of the power systems are in operation and did not change fundamentally, so all the information provided in the book can be considered current; note that it is quite difficult to find any new technical reference sources that would be readable and practical...

In the present latest release of the electrical safety handbook the team of the well respected and recognized authors did a perfect job and brought together nearly all important aspects of the electrical safety. The book covers all major standards relating to the electricity including but not limited to NESC, NFPA, NEC, OSHA, IEEE 1584, 70E. It is a very practical and nicely illustrated source of lifesaving info specifically designed for work environments.

The guide mainly is intended to provide the readers with the up-to-date and actual strategies of the electrical safety to be uses in various commercial/industrial and other electrical systems in a very understandable and easy-to-follow format. The publication has been prepared by the experts in operation, construction, engineering, maintenance and, of course, safety of electrical equipment and systems and delivers necessary details on the electrical hazards, associated safety equipment, procedures and methods, safe maintenance of the electrical equipment, accident prevention and investigation, rescue, first aid, bounding and grounding, low-, medium- and high- voltage safety management, safety training, relevant safety standards, guidelines and requirements etc. We would definitely consider this publication to be a sort of safety resource that anyone dealing with the electrical safety must possess.​

This book features quite informal and accessible style of writing, combined with a simple treatments of math, and a very clear guidelines to applications - all this have made the publication one of the best selling and most popular ones in the fields of electrical engineering and electronics. The readers will find this book comprehensive though very readable.

The authors have emphasized all fundamental ideas that are relevant to the correct understanding of the various electrical properties of materials. All topics in the publication have been selected with the author's intent to explain the principles of construction/operation of various devices used in engineering or proposed for future use in the industry. The use of math has been kept to a minimum owing to choosing the simplest model capable of displaying the essential properties of a phenomenon.

Most of the sections in this book are self contained and might actually be used as background reading. All challenging topics have been explained in this publication and we specifically recommend this reading to anyone having the materials science/materials engineering background. However, it suits everyone - the authors made their best to explain the technology using the introductory-level physics and mathematics.

The issue of the quality of the generated/provided electric power is becoming more and more important for the electric utilities as well as for the end users. Nowadays, the engineers involved in the power quality matters are trying to deal with such issues by means of the system approach.

We would use the "power quality" as the common term to describe the core subject of the present publication; however, it should be noted as necessary that in most of the cases the voltage quality is being addressed. From the technical point of view, power represents the rate of energy delivery and it would be quite difficult to try to define the quality of the power. The book consists of eleven major chapters with the first one being introductory and describing the scope of the book.

The 2nd chapter provides descriptions of most commonly used terms and definitions, the 3rd chapter addresses the voltage sags/interruptions, the 4th deals with the overvoltage problem, the 5th provides the fundamentals of harmonics... the rest of the chapters deal with the applied harmonics, long-duration voltage variations, benchmarking of the power quality, distributed generation, grounding and wiring issues. and monitoring of the power quality. Some of the applicable industry standards have also been mentioned in the last chapter together with the references.
