Neolitsea cassia Neolitsea cassia Neolitsea cassia is a species of tree in the Lauraceae family. It is endemic to Sri Lanka. It is known as "dawulu kurundu - දවුල් කුරුදු" or "kudu dawula - කුඩු දවුල" in Sinhala. Bark - thick, smooth, gray; W- light, hard, pale orange. Montane and rain forest understory. Wood - panelling; leaves- mucilaginous extract used in preparation of local sweet called "aasmi" ; Bark,leaves- medicinal. Straight stem with greyish bark and short, slender branches. The leaf flush is smooth, silvery copper, drooping, crowded at the ends of branchlets, and turn bright green when mature. Leaves are lanceolate
SPICE effect of component variations on performance, a task which is impractical using calculations by hand for a circuit of any appreciable complexity. Circuit simulation programs, of which SPICE and derivatives are the most prominent, take a text netlist describing the circuit elements (transistors, resistors, capacitors, etc.) and their connections, and translate this description into equations to be solved. The general equations produced are nonlinear differential algebraic equations which are solved using implicit integration methods, Newton's method and sparse matrix techniques. SPICE was developed at the Electronics Research Laboratory of the University of California, Berkeley by Laurence Nagel with direction from
