Charley is worried! Her archaeologist parents have been marooned on a sinking island and, when an antique mirror becomes a gateway to another world, she too faces many dangers. But she is helped by Charles, a boy version of herself she meets there, with whom she is unknowingly linked to a great source of magic. They must now flee through further magic mirrors to other worlds, pursued by horrific magical creatures sent by a sinister wizard who wants to tear this secret from them. Charley’s magical aunt accompanies them – at least her spirit does in the body of the cat, Selena. They travel through worlds that are both similar yet unlike their own in different times. They must journey from Charles’ Victorian home, through a future world where magic and science are in harmony, and finally in an ancient Britain where they meet versions of Merlin and Arthur. Finally, on the island of Lyonesse, they face the wizard himself within a magical maze in a desperate battle to rescue her parents and return them safely to their own world and time.
It’s too late! A disastrous end as hundreds of worlds have been corrupted. Mr. Lewnbrawn is a cruel pianist whose soul is being manipulated with one purpose... to unlock all 88 doors. A different secret lies behind each door because behind the tall Gates of Odenton lies his mansion, filled with dark secrets.
This report presents the findings of a research program designed to: a) evaluate current door observation practices and procedures and assess how they relate to transit property characteristics, such as facilities, vehicle configurations, and operating procedures; b) identify the range and scope of existing observation aids and assess their merits relative to their specific applications; c) identify promising observation technologies and define conceptual observation aids based on them; and d) develop guidelines for transit system use in the selection and implementation of observation aids for their specific application.
Until the 1990s, the reduction of the minimum feature sizes used to fabricate in- grated circuits, called “scaling”, has highlighted serious advantages as integration density, speed, power consumption, functionality and cost. Direct consequence was the decrease of cost-per-function, so the electronic productivity has largely progressed in this period. Another usually cited trend is the evolution of the in- gration density as expressed by the well-know Moore’s Law in 1975: the number of devices per chip doubles every 2 years. This evolution has allowed improving signi?cantly the circuit complexity, offering a great computing power in the case of microprocessor, for example. However, since few years, signi?cant issues appeared such as the increase of the circuit heating, device complexity, variability and dif?culties to improve the integration density. These new trends generate an important growth in development and production costs. Though is it, since 40 years, the evolution of the microelectronics always f- lowed the Moore’s law and each dif?culty has found a solution.

Recent years have seen rapid strides in the level of sophistication of VLSI circuits. On the performance front, there is a vital need for techniques to design fast, low-power chips with minimum area for increasingly complex systems, while on the economic side there is the vastly increased pressure of time-to-market. These pressures have made the use of CAD tools mandatory in designing complex systems. Timing Analysis and Optimization of Sequential Circuits describes CAD algorithms for analyzing and optimizing the timing behavior of sequential circuits with special reference to performance parameters such as power and area. A unified approach to performance analysis and optimization of sequential circuits is presented. The state of the art in timing analysis and optimization techniques is described for circuits using edge-triggered or level-sensitive memory elements. Specific emphasis is placed on two methods that are true sequential timing optimizations techniques: retiming and clock skew optimization. Timing Analysis and Optimization of Sequential Circuits covers the following topics: Algorithms for sequential timing analysis Fast algorithms for clock skew optimization and their applications Efficient techniques for retiming large sequential circuits Coupling sequential and combinational optimizations. Timing Analysis and Optimization of Sequential Circuits is written for graduate students, researchers and professionals in the area of CAD for VLSI and VLSI circuit design.
From the rising-star designer and author of the hit blog, Elements of Style, a full-color, fully illustrated book packed with honest advice, inspiration, ideas, and lessons learned about designing a home that reflects your personality and style. Elements of Style is a uniquely personal and practical decorating guide that shows how designing a home can be an outlet of personal expression and an exercise in self-discovery. Drawing on her ten years of experience in the interior design industry, Erin combines honest design advice and gorgeous professional photographs and illustrations with personal essays about the lessons she has learned while designing her own home and her own life—the first being: none of our homes or lives is perfect. Like a funny best friend, she reveals the disasters she confronted in her own kitchen renovation, her struggles with anorexia, her epic fight with her husband over a Lucite table, and her secrets for starting a successful blog. Organized by rooms in the house, Elements of Style invites readers into Erin’s own home as well as homes she has designed for clients. Fresh, modern, and colorful, it is brimming glamour and style as well as advice on practical matters from choosing kitchen counter materials to dressing a bed with pillows, picking a sofa, and decorating a nursery without cartoon characters. You’ll also find a charming foreword by Erin’s husband, Andrew, and an extensive Resource and Shopping Guide that provides an indispensable a roadmap for anyone embarking on their first serious home decorating adventure. With Erin’s help, you can finally make your house your home.
This "current-amplifier cookbook" contains an extensive review of different current amplifier topologies realisable with modern CMOS integration technologies. The book derives the seldom-discussed issue of high-frequency distortion performance for all reviewed amplifier topologies, using as simple and intuitive mathematical methods as possible.
Statistical timing analysis is an area of growing importance in nanometer te- nologies‚ as the uncertainties associated with process and environmental var- tions increase‚ and this chapter has captured some of the major efforts in this area. This remains a very active field of research‚ and there is likely to be a great deal of new research to be found in conferences and journals after this book is published. In addition to the statistical analysis of combinational circuits‚ a good deal of work has been carried out in analyzing the effect of variations on clock skew. Although we will not treat this subject in this book‚ the reader is referred to [LNPS00‚ HN01‚ JH01‚ ABZ03a] for details. 7 TIMING ANALYSIS FOR SEQUENTIAL CIRCUITS 7.1 INTRODUCTION A general sequential circuit is a network of computational nodes (gates) and memory elements (registers). The computational nodes may be conceptualized as being clustered together in an acyclic network of gates that forms a c- binational logic circuit. A cyclic path in the direction of signal propagation 1 is permitted in the sequential circuit only if it contains at least one register . In general, it is possible to represent any sequential circuit in terms of the schematic shown in Figure 7.1, which has I inputs, O outputs and M registers. The registers outputs feed into the combinational logic which, in turn, feeds the register inputs. Thus, the combinational logic has I + M inputs and O + M outputs.
