In the last decade, signi?cant changes have occurred in the ?eld of vehicle motion planning, and for UAVs in particular. UAV motion planning is especially dif?cult due to several complexities not considered by earlier planning strategies: the - creased importance of differential constraints, atmospheric turbulence which makes it impossible to follow a pre-computed plan precisely, uncertainty in the vehicle state, and limited knowledge about the environment due to limited sensor capabilities. These differences have motivated the increased use of feedback and other control engineering techniques for motion planning. The lack of exact algorithms for these problems and dif?culty inherent in characterizing approximation algorithms makes it impractical to determine algorithm time complexity, completeness, and even soundness. This gap has not yet been addressed by statistical characterization of experimental performance of algorithms and benchmarking. Because of this overall lack of knowledge, it is dif?cult to design a guidance system, let alone choose the algorithm. Throughout this paper we keep in mind some of the general characteristics and requirements pertaining to UAVs. A UAV is typically modeled as having velocity and acceleration constraints (and potentially the higher-order differential constraints associated with the equations of motion), and the objective is to guide the vehicle towards a goal through an obstacle ?eld. A UAV guidance problem is typically characterized by a three-dimensional problem space, limited information about the environment, on-board sensors with limited range, speed and acceleration constraints, and uncertainty in vehicle state and sensor data.

The only comprehensive reference work of its kind, this book provides complete coverage of everything that a fund raiser must know when preparing for an international fund-raising campaign. Offers an overview of a country's tax and regulatory system, an examination of its not-for-profit sector, what sources of funding are available, and what fund-raising methods are considered acceptable by the culture and the government.


Next Generation Of International Chemical Additives

RRP $301.95

The objective is writing 'Next Generation Chemical Additives' to identify the next generation chemical additives for eight selected industries. The text will also provide methods for their preparation, additive treatment levels, and testing methods to evaluate additive performance. To ensure optimum performance of materials and products, chemists, formulators, and blenders must be provided with the most current information on existing chemical additives. It is even more essential that corporate operations officers can easily identify the next generation of chemical additives. In addition to this a critical comparison will be given with the existing additives.

  • Structural and physical properties as well as low and elevated temperature toxicity information provided in an easy to understand format
  • Highlights the advantages of the selected additive over existing agents

  • Applications using the newly identified chemical additive provided for existing commercial materials and products

  • The most direct method for preparing the chemical agent described

  • Simplistic and sophisticated method for characterizing the chemical agent provided
