The aim of this book is to explain point-and-figure charting to European investors and traders, and to show why it is the most reliable technical tool for timing entry and exit points in stocks, indices and other securities. The book is written for all levels of trader, from the novice to the experienced. It starts by explaining the basics of point-and-figure, and by showing its advantages over other types of chart. Readers are then given step-by-step instructions on how to start a point-and-figure chart from simple price data, and how to add to it day-by-day using simple rules based on end of day highs and lows. The emphasis is on simplicity and clarity. The section on chart interpretation introduces the basic buy and sell signals, and goes on to explain the more complex signals, in each case illustrating the pattern, and the precise entry and exit points, with colour charts from FTSE stocks and indices. It also shows how trend lines are incorporated into a chart. The latest point-and-figure trading techniques are covered in depth. The authors show how to: use horizontal and vertical counts to estimate the size of price moves, use stop-orders to protect positions, use pyramiding to maximise profitable trends, and use swing trading in combination with p&f. They also show how to adapt your trading style to the amount of capital you have available and to your risk tolerance. In the later sections of the book, the authors concentrate on optimisation of p&f trading and the avoidance of the most common trap - 'over-fitting' - and on analysis of the profitability of p&f trading. They demonstrate conclusively that point and figure, correctly applied, produces consistent and reliable profits across a variety of markets. In summary, Heinrich Weber & Kermit Zieg's book is the definitive guide to the theory and application of point-and-figure charting. It is especially welcome for UK and European traders, since it uses recent charts of FTSE and European securities as examples, and includes hitherto unpublished research on p&f's applicability to European securities.

An important theorem by Beilinson describes the bounded derived category of coherent sheaves on $\mathbb{P n$, yielding in particular a resolution of every coherent sheaf on $\mathbb{P n$ in terms of the vector bundles $\Omega {\mathbb{P n j(j)$ for $0\le j\le n$. This theorem is here extended to weighted projective spaces. To this purpose we consider, instead of the usual category of coherent sheaves on $\mathbb{P ({\rm w )$ (the weighted projective space of weights $\rm w=({\rm w 0,\dots,{\rm w n)$), a suitable category of graded coherent sheaves (the two categories are equivalent if and only if ${\rm w 0=\cdots={\rm w n=1$, i.e. $\mathbb{P ({\rm w )= \mathbb{P n$), obtained by endowing $\mathbb{P ({\rm w )$ with a natural graded structure sheaf. The resulting graded ringed space $\overline{\mathbb{P ({\rm w )$ is an example of graded scheme (in chapter 1 graded schemes are defined and studied in some greater generality than is needed in the rest of the work). Then in chapter 2 we prove This weighted version of Beilinson's theorem is then applied in chapter 3 to prove a structure theorem for good birational weighted canonical projections of surfaces of general type (i.e., for morphisms, which are birational onto the image, from a minimal surface of general type $S$ into a $3$-dimensional $\mathbb{P ({\rm w )$, induced by $4$ sections $\sigma i\in H0(S,\mathcal{O S({\rm w iK S))$). This is a generalization of a theorem by Catanese and Schreyer (who treated the case of projections into $\mathbb{P 3$), and is mainly interesting for irregular surfaces, since in the regular case a similar but simpler result (due to Catanese) was already known. The theorem essentially states that giving a good birational weighted canonical projection is equivalent to giving a symmetric morphism of (graded) vector bundles on $\overline{\mathbb{P ({\rm w )$, satisfying some suitable conditions. Such a morphism is then explicitly determined in chapter 4 for a family of surfaces with numerical invariant

Now in full color, the 10th anniversary edition of this classic book takes you deep into the influences that underlie modern video games, and examines the elements they share with traditional games such as checkers. At the heart of his exploration, veteran game designer Raph Koster takes a close look at the concept of fun and why it’s the most vital element in any game. Why do some games become boring quickly, while others remain fun for years? How do games serve as fundamental and powerful learning tools? Whether you’re a game developer, dedicated gamer, or curious observer, this illustrated, fully updated edition helps you understand what drives this major cultural force, and inspires you to take it further. You’ll discover that: Games play into our innate ability to seek patterns and solve puzzles Most successful games are built upon the same elements Slightly more females than males now play games Many games still teach primitive survival skills Fictional dressing for modern games is more developed than the conceptual elements Truly creative designers seldom use other games for inspiration Games are beginning to evolve beyond their prehistoric origins
