This paper deals with part sequencing and optimal robot moves sequence in 2-machine robotic cells according to Petri net graph. We have assumed that the robotic cell is capable of producing same and different parts. We have considered a new motion cycle for robot moves sequence which is the development of existing motion cycles in 2-machine robotic cells. The main goal of this study is to minimize the cycle time by determining the optimal part sequencing and robot moves sequence in the robotic cell. So, we have proposed a model based on Petri network.

半径小于等于550 m的圆曲线路段是车辆易产生高碳排的路段。为揭示载重柴油车在这些小半径圆曲线路段的二氧化碳排放水平变化规律,以moves模型为基础,应用符合我国实际情况的道路、交通、车辆、燃油等信息,对moves模型中的参数做本地化修正及设置。通过采用moves模型进行载重柴油车碳排放模拟,得到了不同平面线形及行驶速度组合条件下的碳排量数据库。在此基础上,首先采用回归分析的方法分别建立了单位圆曲线长碳排量与圆曲线半径、圆曲线长度、车辆驶入圆曲线路段的初始速度3个参数的关系模型,其次采用迭代的方法建立了小半径圆曲线路段载重柴油车累积碳排放量预测模型。通过实地油耗试验,选用IPCC碳排放核算方法,将车辆油耗数据转换成碳排放数据,对比了碳排量核算值与模型预测值,验证了模型的预测精度。结果表明:单位圆曲线长碳排量以圆曲线半径、车辆驶入圆曲线路段的初始速度这2个参数分别为变量作二次函数形式的变化,以圆曲线长度为变量作幂函数形式的变化;累积碳排量以上述3个参数为变量作多元非线性函数形式的变化;经过参数本地化修正及设置的moves模型可以用于我国实际道路交通条件下的载重柴油车碳排放水平预测,以moves模拟为基础而建立的多元碳排量模型预测值与试验实测值的相对误差平均值为6. 02%,小于10%,具有较高的预测精度,可以在无需借助moves模型的情况下方便、快速地估算载重柴油车在小半径圆曲线路段的碳排量。

为研究高速公路纵坡路段的碳排放规律,以西安绕城高速为依托工程进行现场试验,采用moves进行碳排放模拟,并利用试验核算的碳排放数据评估模拟结果。基于moves模型得到我国高速公路不同纵坡情况下的碳排量数据库文件,建立高速公路纵坡路段的载重汽车的碳排放模型,并对碳排放模型进行敏感性分析。研究结果表明:高速公路纵坡路段的碳排放量以初速度、坡度、坡长为自变量作多元非线性函数形式的变化;高速公路上坡路段是机动车产生碳排放的主要路段,累计碳排量对坡度i_(上坡_∈[3%,6%]的敏感性居第一位次,对坡长l_(上坡)的敏感性居第二位次,反映出路线设计过程应尽量采用较小纵坡,避免长大纵坡的设计方案;在高速公路下坡路段,累计碳排放对坡度i_(下坡)∈[-3%,-6%]的变化最敏感,坡长次之。

Open Journal of Discrete Mathematics 2013年第3期3卷 151-154页

Using geometric techniques, formulas for the number of squares that require k moves in order to be reached by a sole knight from its initial position on an infinite chessboard are derived. The number of squares reachable in exactly k moves are 1, 8, 32, 68, and 96 for k = 0, 1, 2, 3, and 4, respectively, and 28k – 20 for k ≥ 5. The cumulative number of squares reachable in k or fever moves are 1, 9, 41, and 109 for k = 0, 1, 2, and 3, respectively, and 14k2 – 6k + 5 for k ≥ 4. Although these formulas are known, the proofs that are presented are new and more mathematically accessible then preceding proofs.

The development of science and technology has made it not only possible but very convenient for people living in different parts of the world to communicate with each other, thus bringing forth a new form of communication: computer-mediated communication (CMC). Text-based CMC is one of the most popular forms of CMC in which people send instant messages to others in different settings. Since this mode of interaction combines features of both the written and spoken language (Greenfield & Subrahmanyam, 2003), it's of great interest whether it follows the same sequential rule as the telephone conversation. However, compared to telephone conversations, computer-mediated communication has received much less attention, let alone text-based CMC. The existing body of literature mostly focuses on content analysis and linguistic features but neglects the sequential organization of such interaction (Paolillo, 1999; Greenfield and Subrahmanyam, 2003; Herring, 1999). In light of this, this paper examines the opening moves of instant message exchanges among Chinese adults in an attempt to find out the unique features characterizing the way they open an online chat. The framework that was chosen for data analysis was the sequential model proposed by Schegloff for American telephone openings.
