this paper presents a new method of lossless image compression. An image is characterized by homogeneous parts. the bit planes, which are of high weight are characterized by sequences of 0 and 1 are successive encoded with RLE, whereas the other bit planes are encoded by the arithmetic coding (AC) (static or adaptive model). By combining an AC (adaptive or static) with the RLE, a high degree of adaptation and compression efficiency is achieved. the proposed method is compared to both static and adaptive model. Experimental results, based on a set of 12 gray-level images, demonstrate that the proposed scheme gives mean compression ratio that are higher those compared to the conventional arithmetic encoders.

对苏丹南穆格莱德裂谷盆地１２０公里长的北东南西向横剖面成熟度和生油进行了模拟。该剖面穿过尤尼蒂和凯冈地区，在这两个地区有井控资料，用于控制根据重力和地震反射剖面作出的构造解释。利用校正后的井底温度进行地热模拟，得出井控地区目前的热流值是６０ｍＷ／ｍ＾２。在利用测定的镜质体数据作为刻度的条件下，采用与当前热流值相似的恒定古热流值或者采用与裂谷相关的复杂的热流样式，都可以很好地对成熟度进行模拟。
