polystyrene (PS), polypropylene (PP) and polyethylene (PE). Polyethylene can form with different densities. These include low density (LDPE), linear low density (LLDPE), medium density (MDPE), high density (HDPE), and ultra-high density (UHDPE). It is possible for samples of LLDPE to take on characteristics of either LDPE or HDPE.
yield and air content. After the density is determined, the yield and air content can then be calculated using given formulas. Density (unit weight) is a measure of weight per unit volume and is expressed in lbs/ft³ or kg/m³. The density of fresh concrete is similar to the density of hardened concrete. After the unit weight is determined ...

It is also common to express pulp yield as air-dry or oven-dry tons of pulp per cord or other unit of wood volume. Alternatively, the reciprocal of these measures indicates the number of cords or other wood unit required per ton of pulp. In addition to the factors discussed above, these measures are affected by wood density. Yield is
of density in kilogram per cubic metre. Let us consider another physical quantity like force. From Newton’s second law of motion, force can be defined as the product of mass and acceleration. We can therefore take the unit of force as 1 kilogram 1 metre/second2. We call this by the name, Newton for convenience. The unit of energy is Newton-metre.

the distributions that need to be approximated. Distributions with densities that are very non-smooth and have tremendous integrated curvature (i.e., lots of wiggles) may require large numbers of normal components. The success of normal mixture models is also tied to the methods of inference. Given that many multivariate density ap-
