This paper presents a new method to decrease the error of real time numerical integration in an Inertial Navigation System (INS), which is widely used in aircrafts, spacecrafts, and field robotics. The well-known Runge–Kutta method is often used for real time numerical integration in INS algorithms. Here a combination of the composite Simpson's 1/3 and 3/8 rules is developed to effectively reduce the total integration error, named Subtractive Composite Simpson Method (SCSM). Also we propose a new method that efficiently reduces the error of the integrator block using the combination of a fourth-order Runge–Kutta (RK4) and SCSM. Simulation results show one order of magnitude decrease in position error after double integration of acceleration value. Extra accuracy gain using this new method makes it possible to choose low cost inertial sensors to realize a low cost INS.

Specific Orientation

Investigations which require electron microscope examination of a few specific areas of non-homogeneous tissues make random sampling of small blocks an inefficient and unrewarding procedure. Therefore, several investigators have devised methods which allow obtaining sample blocks for electron microscopy from region of tissue previously identified by light microscopy of present here techniques which make possible: 1) sampling tissue for electron microscopy from selected areas previously identified by light microscopy of relatively large pieces of tissue; 2) dehydration and embedding large numbers of individually identified blocks while keeping each one separate; 3) a new method of maintaining specific orientation of blocks during embedding; 4) special light microscopic staining or fluorescent procedures and electron microscopy on immediately adjacent small areas of tissue.
