Solar Energy: The Physics and Engineering of Photovoltaic Conversion, Technologies and Systems

This book uniquely covers both the physics of photovoltaic (PV) cells and the design of PV systems for real-life applications. - Fundamental principles of semiconductor solar cells. - PV technology: crystalline silicon solar cells; thin-film cells; PV modules; third-generation concepts. - PV systems, from simple stand-alone, to complex systems connected to the grid; components; design; deployment; performance. The book is an invaluable reference for researchers, industrial engineers and designers working in solar energy generation. The book is also ideal for university and third-level physics or engineering courses on solar photovoltaics, with exercises to check students' understanding and reinforce learning. It is the perfect companion to the Massive Open Online Course (MOOC) on Solar Energy (DelftX, ET.3034TU) presented by co-author Arno Smets. The course is available in English on the nonprofit open source platform, and in Arabic on Over 100,000 students have already registered for these MOOCs.

Mathematics for the Physical Sciences

Introduction to and use of complex analysis and algebraic techniques to understand the solution of boundary value problems. Physics examples serve to introduce the fundamental partial differential equations and "special functions" of mathematical physics. A thorough analysis of Green's functions leads to a discussion of integral equations. Supplementary topics include dispersion relations and rational function approximation.

Eating to win: activity, diet and weight control

What should we eat before and after exercise? This free course, Eating to win: activity, diet and weight control, examines the importance of nutrition in physical activity, sport and weight management. The role that physical activity has alongside nutrition in controlling body weight will be discussed, as will considerations for pre-exercise and post-exercise nutrition and hydration.

Developing Your Intuition: 5 Simple Steps To Help You Live a More Intuitive Life

***For a limited time, you can get this author's latest book, The Yin & Yang Lifestyle Guide, for free - click here to find out more > (just copy and paste into your browser)***

The little book will help you connect more readily and easily with your intuition. We all have the capacity for intuitive insight; in fact, intuition is already within us - whether we are aware of it or not.

Having intuition doesn't involve having psychic powers or having to visualize white lights coming out of our heads. These common "new age" style techniques are not at all necessary to develop our intuition. In some cases, these techniques further impair our capacity to be intuitive simply because it can add more clutter into our minds. Developing your intuition is not about adding more or wanting more, it's about throwing things out and wanting less - when we have cultivated a healthy space within, we can hear, see and feel our intuition more clearly.

This book will help you to understand what intuition is and why it is an important part of our lives. It will outline some very simple and progressive steps to take in order to de-clutter the mind so that you can become more aware and sensitive to your intuitive abilities.

Transforming ADHD: Practical Exercises: Companion Book to Transforming ADHD: Simple, Effective Attention and Action Regulation Skills to Help You Focus and Succeed

When you have ADHD, you have obstacles to trying strategies & skills. The biggest obstacle may be, first, remembering them &, second, practicing them when you do.

The thing is, with ADHD, it's the nature of the beast to forget, procrastinate, & remain optimistic that tomorrow will be different. But, with ADHD, next time & tomorrow often mean never or too late.


Because you're unable to count on your brain to guide your attention & action toward your intentions. You need external guides. If partly blind, would you rely on sight to navigate the world? Squint, stare & see what happens? Likely you'd welcome external resources (e.g., a dog) to augment your vision. The good news? External guides surround you.

Images, sounds, vibrations are external guides. They call your attention to all kinds of things. An exciting book cries, "Read me." A phone says "Look!" The trick to guides is having the right ones & reducing their competition (e.g., with social media).

Guides offer the possibility of adaptive neurodiversity. Rather than being about changing your brain, guides are about knowing your brain and what gives you the best chance of mastery and control.

In TRANSFORMING ADHD: SIMPLE, EFFECTIVE ATTENTION AND ACTION REGULATION SKILLS TO HELP YOU FOCUS AND SUCCEED, Greg Crosby, LPC & I had no room to include guides for the book's exercises. This e-book fills this gap & introduces many of its exercises to readers without the book.

I designed the pages to be handouts of sorts, if you'd like to print them for your personal use (consider this my permission at least). Having them posted or placed where needed to guide your behavior works best. Posting them may also be one of your motivational strategies. I wish you success.
