Camping along the Big Long River Summary In this paper, the problem that allows more parties entering recreation system is investigated. In order to let park managers have better arrangements on camping for parties, the problem is divided into four sections to consider. The first section is the description of the process for single-party's rafting. That is, formulating a Status Transfer Equation of a party based on the state of the arriving time at any campsite. Furthermore, we analyze the encounter situations between two parties. Next we build up a simulation model according to the analysis above. Setting that there are recreation sites though the river, count the encounter times when a new party enters this recreation system, and judge whether there exists campsites available for them to station. If the times of encounter between parties are small and the campsite is available, the managers give them a good schedule and permit their rafting, or else, putting off the small interval time t until the party satisfies the conditions. Then solve the problem by the method of computer simulation. We imitate the whole process of rafting for every party, and obtain different numbers of parties, every party's schedule arrangement, travelling time, numbers of every campsite's usage, ratio of these two kinds of rafting boats, and time intervals between two parties' starting time under various numbers of campsites after several times of simulation. Hence, explore the changing law between the numbers of parties (X) and the numbers of campsites (Y) that X ascends rapidly in the first period followed by Y's increasing and the curve tends to be steady and finally looks like a S curve. In the end of our paper, we make sensitive analysis by changing parameters of simulation and evaluate the strengths and weaknesses of our model, and write a memo to river managers on the arrangements of rafting.

眼科病床的合理安排 摘要 医院病床的合理安排是病人和医院共同关注的问题。本文对医院病床的分配进行分析,使用层次分析法找出模型的判定因素,通过对医院已制定的模型的判断,找出了原模型的优劣,并使用线性规划制定出合理的模型,通过模型的结果推断出第三问的答案,若该住院部周六、周日不安排手术,则改变模型的约束条件,使其判断之后的手术时间是否要做出相应的调整。考虑到便于医院进行管理,提出运用排队论的方法求解出病床比例分配模型。 关键词:层次分析法线性规划排队论 一、问题重述 医院就医排队是大家都非常熟悉的现象,它以这样或那样的形式出现在我们面前,例如,患者到门诊就诊、到收费处划价、到药房取药、到注射室打针、等待住院等,往往需要排队等待接受某种服务。 我们考虑某医院眼科病床的合理安排的数学建模问题。 该医院眼科门诊每天开放,住院部共有病床79张。该医院眼科手术主要分四大类:白内障、视网膜疾病、青光眼和外伤。附录中给出了2008年7月13日至2008年9月11日这段时间里各类病人的情况。 白内障手术较简单,而且没有急症。目前该院是每周一、三做白内障手术,此类病人的术前准备时间只需1、2天。做两只眼的病人比做一只眼的要多一些,大约占到60%。如果要做双眼是周一先做一只,周三再做另一只。 外伤疾病通常属于急症,病床有空时立即安排住院,住院后第二天便会安排手术。 其他眼科疾病比较复杂,有各种不同情况,但大致住院以后2-3天内就可以接受手术,主要是术后的观察时间较长。这类疾病手术时间可根据需要安排,一般不安排在周一、周三。由于急症数量较少,建模时这些眼科疾病可不考虑急症。 该医院眼科手术条件比较充分,在考虑病床安排时可不考虑手术条件的限制,但考虑到手术医生的安排问题,通常情况下白内障手术与其他眼科手术(急

The Keep-Right-Except-To-Pass Rule Summary As for the first question, it provides a traffic rule of keep right except to pass, requiring us to verify its effectiveness. Firstly, we define one kind of traffic rule different from the rule of the keep right in order to solve the problem clearly; then, we build a Cellular automaton model and a Nasch model by collecting massive data; next, we make full use of the numerical simulation according to several influence factors of traffic flow; At last, by lots of analysis of graph we obtain, we indicate a conclusion as follow: when vehicle density is lower than 0.15, the rule of lane speed control is more effective in terms of the factor of safe in the light traffic; when vehicle density is greater than 0.15, so the rule of keep right except passing is more effective In the heavy traffic. As for the second question, it requires us to testify that whether the conclusion we obtain in the first question is the same apply to the keep left rule. First of all, we build a stochastic multi-lane traffic model; from the view of the vehicle flow stress, we propose that the probability of moving to the right is 0.7and to the left otherwise by making full use of the Bernoulli process from the view of the ping-pong effect, the conclusion is that the choice of the changing lane is random. On the whole, the fundamental reason is the formation of the driving habit, so the conclusion is effective under the rule of keep left. As for the third question, it requires us to demonstrate the effectiveness of the result advised in the first question under the intelligent vehicle control system. Firstly, taking the speed limits into consideration, we build a microscopic traffic simulator model for traffic simulation purposes. Then, we implement a METANET model for prediction state with the use of the MPC traffic controller. Afterwards, we certify that the dynamic speed control measure can improve the traffic flow . Lastly neglecting the safe factor, combining the rule of keep right with the rule of dynamical speed control is the best solution to accelerate the traffic flow overall. Key words:Cellular automaton model Bernoulli process Microscopic traffic simulator model The MPC traffic control

“空瓶换汽水”问题探讨 摘要:“空瓶换汽水”问题是一个比较经典的趣味数学问题,曾以“空瓶换啤酒”“废电池换新电池”“费电珠换新电珠”等形式出现在前苏联、德国和中国各种数学竞赛题目中。这个问题的探讨与解决,对于我们在日常生活中如何使开支与效益达到最优化等问题,具有一定的指导意义。 关键词:瓶数空瓶不含瓶单价推论 日常生活中,我们经常遇到过空瓶换汽水问题。喝完了凉爽的汽水还能用空瓶换汽水继续喝,那简直是炎炎夏日里的一种享受。如果没有经历过,那么以下这几道数学题你应该似曾相识。 【问题一】 某品牌汽水可以用3个空瓶再换回1瓶汽水,某人买回10瓶汽水,则他最多可以喝到多少瓶汽水 【解析一】 “用3个空瓶再换回1瓶汽水”,假设汽水一瓶3元,则空瓶相应的1元,而真正的汽水就只值2元,“某人买回10瓶汽水”意味着花去人民币 3*10=30元, 故而“最多可以喝到?30/2=15瓶。 【问题二】 5个空瓶可以换1瓶汽水,某班同学喝了161瓶汽水,其中有一些是用喝剩下来的空瓶换的,那么他们至少要买汽水多少瓶? 【解析二】 同理“5个空瓶可以换1瓶汽水”由题意,假设1瓶汽水5元,空瓶则1元,真正的汽水只值4元,“某班同学喝了161瓶汽水”则一共真正汽水的钱是:161*4元; 而买整个汽水(真正的汽水加空瓶)需要5元,所以“他们至少要买汽水多少瓶”则等于( 161*4)/5=(161/5)*4=(32*4)...余1,此时就可算出32*4+1=129瓶。 笔者对类似的题目的思考与研究,得到以下推论: 1,汽水的瓶数=总共的钱/汽水(不含瓶)的钱; 2,至少要买汽水多少瓶=总花去的钱/汽水的单价+余数。 这些推论是否正确呢是否可以解决此类问题呢我们不妨拿类似的问题验证一下。 【问题三】 超市规定每3个空汽水瓶可以换一瓶汽水,小李有12个空汽水瓶,最多可以换几瓶汽水A.4瓶B.5瓶C.6瓶D.7瓶 【解答三】 由题意可知,空汽水瓶的价钱是1元,汽水加瓶是3元,所以“小李有12个空汽水瓶”等于小李有12元钱,问题是“最多可以换几瓶汽水”,就是小李

Titile Summary During cell division, mitotic spindles are assembled by microtubule-based motor proteins1, 2. The bipolar organization of spindles is essential for proper segregation of chromosomes, and requires plus-end-directed homotetrameric motor proteins of the widely conserved kinesin-5 (BimC) family3. Hypotheses for bipolar spindle formation include the 'push?pull mitotic muscle' model, in which kinesin-5 and opposing motor proteins act between overlapping microtubules2, 4, 5. However, the precise roles of kinesin-5 during this process are unknown. Here we show that the vertebrate kinesin-5 Eg5 drives the sliding of microtubules depending on their relative orientation. We found in controlled in vitro assays that Eg5 has the remarkable capability of simultaneously moving at 20 nm s-1 towards the plus-ends of each of the two microtubules it crosslinks. For anti-parallel microtubules, this results in relative sliding at 40 nm s-1, comparable to spindle pole separation rates in vivo6. Furthermore, we found that Eg5 can tether microtubule plus-ends, suggesting an additional microtubule-binding mode for Eg5. Our results demonstrate how members of the kinesin-5 family are likely to function in mitosis, pushing apart interpolar microtubules as well as recruiting microtubules into bundles that are subsequently polarized by relative sliding. We anticipate our assay to be a starting point for more sophisticated in vitro models of mitotic spindles. For example, the individual and combined action of multiple mitotic motors could be tested, including minus-end-directed motors opposing Eg5 motility. Furthermore, Eg5 inhibition is a major target of anti-cancer drug development, and a well-defined and quantitative assay for motor function will be relevant for such developments

美赛一等奖经验总结

当我谈数学建模时我谈些什么——美赛一等奖经验总结 作者:彭子未 前言:2012 年3月28号晚,我知道了美赛成绩,一等奖(Meritorus Winner),没有太多的喜悦,只是感觉释怀,一年以来的努力总算有了回报。从国赛遗憾丢掉国奖,到美赛一等,这一路走来太多的不易,感谢我的家人、队友以及朋友的支持,没有你们,我无以为继。 这篇文章在美赛结束后就已经写好了,算是对自己建模心得体会的一个总结。现在成绩尘埃落定,我也有足够的自信把它贴出来,希望能够帮到各位对数模感兴趣的同学。 欢迎大家批评指正,欢迎与我交流,这样我们才都能进步。 个人背景:我2010年入学,所在的学校是广东省一所普通大学,今年大二,学工商管理专业,没学过编程。 学校组织参加过几届美赛,之前唯一的一个一等奖是三年前拿到的,那一队的主力师兄凭借这一奖项去了北卡罗来纳大学教堂山分校,学运筹学。今年再次拿到一等奖,我创了两个校记录:一是第一个在大二拿到数模美赛一等奖,二是第一个在文科专业拿数模美赛一等奖。我的数模历程如下: 2011.4 校内赛三等奖 2011.8 通过选拔参加暑期国赛培训(学校之前不允许大一学生参加) 2011.9 国赛广东省二等奖 2011.11 电工杯三等奖 2012.2 美赛一等奖(Meritorious Winner) 动机:我参加数学建模的动机比较单纯,完全是出于兴趣。我的专业是工商管理,没有学过编程,觉得没必要学。我所感兴趣的是模型本身,它的思想,它的内涵,它的发展过程、它的适用问题等等。我希望通过学习模型,能够更好的去理解一些现象,了解其中蕴含的数学机理。数学模型中包含着一种简洁的哲学,深刻而迷人。 当然获得荣誉方面的动机可定也有,谁不想拿奖呢? 模型:数学模型的功能大致有三种:评价、优化、预测。几乎所有模型都是围绕这三种功能来做的。比如,今年美赛A题树叶分类属于评价模型,B题漂流露营安排则属于优化模型。 对于不同功能的模型有不同的方法,例如评价模型方法有层次分析、模糊综合评价、熵值法等;优化模型方法有启发式算法(模拟退火、遗传算法等)、仿真方法(蒙特卡洛、元胞自动机等);预测模型方法有灰色预测、神经网络、马尔科夫链等。在数学中国网站上有许多关于这些方法的相关介绍与文献。

2019 MCM/ICM Summary Sheet (Your team's summary should be included as the first page of your electronic submission.) Type a summary of your results on this page. Do not include the name of your school, advisor , or team members on this page. Ecosystems provide many natural processes to maintain a healthy and sustainable environment after human life. However, over the past decades, rapid industrial development and other anthropogenic activities have been limiting or removing ecosystem services. It is necessary to access the impact of human activities on biodiversity and environmental degradation. The main purpose of this work is to understand the true economic costs of land use projects when ecosystem services are considered. To this end, we propose an ecological service assessment model to perform a cost benefit analysis of land use development projects of varying sites, from small-scale community projects to large national projects. We mainly focus on the treatment cost of environmental pollution in land use from three aspects: air pollution, solid waste and water pollution. We collect pollution data nationwide from 2010 to 2015 to estimate economic costs. We visually analyze the change in economic costs over time via some charts. We also analyze how the economic cost changes with time by using linear regression method. We divide the data into small community projects data (living pollution data) and large natural data (industrial pollution data). Our results indicate that the economic costs of restoring economical services for different scales of land use are different. For small-scale land, according to our analysis, the treatment cost of living pollution is about 30 million every year in China. With the rapid development of technology, the cost is lower than past years. For large-scale land, according to our analysis, the treatment cost of industrial pollution is about 8 million, which is lower than cost of living pollution. Meanwhile the cost is trending down due to technology development. The theory developed here provides a sound foundation for effective decision making policies on land use projects. Key words: economic cost , ecosystem service, ecological service assesment model, pollution.
