In this study, a pulp beating machine was used to premix the pulp fibers with high density polyethylene (HDPE) particles in water. The wet or pre-dried pulp fiber/HDPE mixture was then melt-compounded by a twin screw extruder. For further improving the dispersion of pulp fiber, some mixture was forced to pass through the twin-screw extruder twice. The resulting mixture was compression molded to...

The refrigeration cycle with the thro~tling device has moe work power consumption and less refrigeration capacity than tha~ with the expander. It is S':Jggested that substituting the expander for the throttling device in the refrigeration cycle should be the efficient way for saving the energy of the refrigeration system. Up to now, the design and ~anufacturing of the two-phase expander seems t...

A compact multicolor beam illuminator and a compact multicolor beam expander are presented. The illuminator performs the dual task of demultiplexing a narrow red-green-blue (RGB) input beam into three separate beams, each of a different color, and expanding them to yield three separate magnified plane waves. The beam expander expands a narrow RGB input beam into a single magnified RGB plane wav...

Overview If ALIGNs or NOTIFYs are corrupted, but they are replaced in the data stream by expander(s) with valid ERROR primitives, the elasticity buffer of an expander or the frame recipient could overflow at a later time. If the expander determines that its elasticity buffer is full and it is expecting an ALIGN, it should be allowed to delete the invalid dword (assuming it might have been an AL...

The processing during extrusion can be done either in the steady or transient state. In the first case, all components are added continuously in the extruder and the machine produces great quantities of mixed compound. In the transient state, the polymer that will form the matrix is fed continuously in the extruder and all other components are added as a single or multiple pulse. The mixed mate...

Families of expander graphs are sparse graphs such that the number of vertices in each graph grows yet each graph remains difficult to disconnect. Expander graphs are of great importance in theoretical computer science. In this paper we study the connection between the Cheeger constant, a measure of the connectivity of the graph, and the smallest nonzero eigenvalue of the graph Laplacian. We sh...

In the present article, a model of scroll expander will be introduced. This model is able to evaluate the performance of a given machine with influence of the geometry. Several losses are also included by the model such as internal leakages, heat transfers or mechanical losses. The forces generated by the gas pressure on the involutes can also be calculated. That expander model is used in order...

Four different ways of obtaining low-density parity-check codes from expander graphs are considered. For each case, lower bounds on the minimum stopping set size and the minimum pseudocodeword weight of expander (LDPC) codes are derived. These bounds are compared with the known eigenvalue-based lower bounds on the minimum distance of expander codes. Furthermore, Tanner’s parity-oriented eigenva...
