A fingerprint reading system includes a camera module, a control module, and a signal processing module. For each candidate column pair remaining after simultaneously generating column pairs, pruning pairs not satisfying specified heuristic constraints, and eliminating pairs with trivial instances of correlation, a random sample of data values is collected. Furthermore, the present invention provides a hybrid gasification system having a structure in which unreacted substances and tar within synthetic gas generated from a first reaction chamber reacts within a second reaction chamber, thereby increasing the entire gasification efficiency. The mechanisms determine whether the critical real time thread currently accessing the scoped memory area is in a defined state so as to accommodate garbage collection of the scoped memory area. In addition, \u03946-TGF-\u03b22 can be used to slow aging and extend longevity.
