Lane changing assistance strategy based on an improved probabilistic model of dynamic occupancy grids

引用

Frontiers of Information Technology & Electronic Engineering 2021年第11期22卷 1492-1504页

作者： Zhengcai YANG zhenhai GAO Fei GAO Xinyu WU Lei HE State Key Laboratory of Automotive Simulation and Control Jilin UniversityChangchun130022China School of Automotive Engineering Hubei University of Automotive TechnologyShiyan442002China

Lane changing assistance in autonomous vehicles is a popular research topic. Scene modeling of the driving area is a prerequisite for lane changing decision problems. A road environment representation method based on a dynamic occupancy grid is proposed in this study. The model encapsulates the data such as vehicle speed, obstacles, lane lines, and traffic rules into a form of spatial drivability probability. This information is compiled into a hash table, and the grid map is mapped into a hash map by means of hash function. A vehicle behavior decision cost equation is established with the model to help drivers make accurate vehicle lane changing decisions based on the principle of least cost, while considering influencing factors such as vehicle drivability, safety, and power. The feasibility of the lane changing assistance strategy is verified through vehicle tests, and the results show that the lane changing assistance system based on a probabilistic model of dynamic occupancy grids can provide lane changing assistance to drivers taking into consideration the dynamics and safety.

Background:A fixed 8-cycle oxaliplatin and capecitabine(XELOX)regimen has been the standard adjuvant therapy for patients with stage III colon ***,completing the full-cycle of oxaliplatin is often associated with severe *** spare patients from the toxic effects,without comprising the required efficacy,we evaluated the safety and efficacy of a modified XELOX(mXELOX)adjuvant chemotherapy regimen with 6 cycles of oxaliplatin and a full cycle of ***:We retrospectively analyzed 330 eligible patients with stage III colon cancer who underwent cura-tive tumor resection followed by mXELOX,standard XELOX or unfinished XELOX adjuvant chemotherapy between December 2007 and April *** prognostic factors were investigated and their disease-free survival(DFS)and overall survival(OS)rates were also determined and compared among the different regimen ***:Compared with the standard XELOX group,the mXELOX group had lower total incidence rates of neuro-toxicity(39.3%vs.76.2%,P<0.001),leucopenia(53.6%vs.69.8%,P=0.017)and thrombocytopenia(38.1%vs.56.3%,P=0.011).The standard XELOX and mXELOX adjuvant chemotherapy regimens presented with comparable 3-year DFS rates(86.3%vs.89.2%;P=0.838)and 3-year OS rates(92.7%vs.97.6%;P=0.227).Compared to unfinished XELOX chemotherapy,the oncologic benefits of the mXELOX regimen were greater for patients with T4 tumors(3-year DFS:Hazard ratio[HR],2.184;95%confidence interval[CI],1.051-4.540;P=0.036;3-year OS:HR,4.529;95%CI 1.245-16.479;P=0.022)and for high-risk patients(3-year DFS:HR,1.962;95%CI 0.964-3.993;P=0.044;3-year OS:HR,4.193;95%CI 1.182-14.874;P=0.026).Conclusions:The mXELOX adjuvant chemotherapy presented a comparable survival benefit and lower incidence of toxicity than standard XELOX *** could be an alternative treatment for high-risk patients with operated stage III colon cancer.

泥岩盖层内断裂垂向封闭油气能力综合评价方法

石油地球物理勘探 2019年第3期54卷 650-655,489页

泥岩盖层内断裂垂向封闭油气能力主要受断层岩排替压力、泥岩盖层断接厚度和下伏储层油气剩余压力的影响,断层岩排替压力越大、泥岩盖层断接厚度越大、下伏储层油气剩余压力越小,泥岩盖层内断裂垂向封闭油气能力越强;反之则越弱。通过... 详细信息

泥岩盖层内断裂垂向封闭油气能力主要受断层岩排替压力、泥岩盖层断接厚度和下伏储层油气剩余压力的影响,断层岩排替压力越大、泥岩盖层断接厚度越大、下伏储层油气剩余压力越小,泥岩盖层内断裂垂向封闭油气能力越强;反之则越弱。通过确定断层岩排替压力、泥岩盖层断接厚度和下伏储层剩余压力,根据油气在下伏储层剩余压力的作用下通过泥岩盖层内断裂渗滤、散失速度的相对大小,建立了一套泥岩盖层内断裂垂向封闭油气能力的综合评价方法。对海拉尔盆地贝尔凹陷呼和诺仁构造的断裂垂向封闭油气能力综合评价结果表明:油气在剩余压力作用下通过14个测点处大一段泥岩盖层内断裂F1渗滤、散失速度均小于0,表明大一段泥岩盖层内断裂F1垂向封闭油气能力均相对较强,有利于油气在南二段聚集与保存,与目前断裂F1附近南二段已发现大量油气分布相吻合,说明文中方法适用于综合评价泥岩盖层内断裂垂向封闭油气能力。
