  • Engineering often involves applying a consistent, structured approach to the solving of problems. A general problem-solving approach and method can be defined, although variations will be required for specific problems. Problems must be approached methodically, applying an algorithm, or step-by-step procedure by which one arrives at a solution.

  • Building on MATLAB (the language of technical computing), Simulink provides a platform for engineers to plan, model, design, simulate, test and implement complex electromechanical, dynamic control, signal processing and communication systems. Simulink-Matlab combination is very useful for developing algorithms, GUI assisted creation of block diagrams and realisation of interactive simulation based designs. The eleven chapters of the book demonstrate the power and capabilities of Simulink to solve engineering problems with varied degree of complexity in the virtual environment....

  • MATLAB (MATrix LABoratory) is an interactive technical computing environment for scientific and engineering applications. It integrates numerical analysis, matrix computation, signal processing, and graphics in an easy-to-use environment. By using its relatively simple programming capability, MATLAB can be easily extended to create new functions. MATLAB is further enhanced by numerous toolboxes such as the Signal Processing Toolbox.

  • Starting MATLAB on Windows Platforms To start MATLAB on a Microsoft Windows platform, double-click the MATLAB shortcut icon on your Windows desktop. The shortcut was automatically created by the installer in the installation directory. If you start MATLAB from a DOS window, type matlab at the DOS prompt. After starting MATLAB, the MATLAB desktop opens – see Chapter 2, “Using the Desktop.” If you use a virus scanner, your settings may slow down MATLAB startup. For example, if you use McAfee VirusScan, set the options to scan program files only....

  • Starting MATLAB Startup Options You can define startup options for MATLAB, which instruct MATLAB to perform certain operations upon startup. There are two ways to specify startup options for MATLAB: • “Using the Startup File for MATLAB, startup.m” on page 1-5 • “Adding Startup Options for Windows Platforms” on page 1-5 or “Adding Startup Options for UNIX Platforms” on page 1-7 Using the Startup File for MATLAB, startup.m At startup, MATLAB automatically executes the master M-file matlabrc.m and, if it exists, startup.m. The file matlabrc.

  • A purchaser should assess the environmental risks associated with a property being purchased. In Canada, government o"cials do not “certify” that a property is free from such risks. A property’s environmental status can be ascertained by inspecting applicable company and public records. In virtually all cases, a purchaser will want to do an “environmental audit” of the property which may include conducting scienti!c testing and a technical analysis of the property. Lending institutions often require such an audit before advancing any funds.

  • In the case studies, lack of institutional capacity and non-transparent processes that did not involve local consultation led to overlapping land claims, conflict, and negative outcomes for local communities. Weak land governance creates challenges to reigning in opportunistic behavior by elites, e.g. by ensuring proper consultation with local and indigenous populations and makes it difficult to appreciate the true value of a piece of land. In many cases this appears to have resulted in land being transferred at implicit values that were well below its opportunity cost.
