-精选财经经济类资料- -最新财经经济资料-感谢阅读- 1 国际学术会议发言稿(精选多篇) 1. prologue thank you, mr. chairman, for your gracious introduction. i am honored to have the chance to address you on this special occasion. the topic of my paper is “transaction cost and farmers choice of agricultural products selling”. the outline of my talk as follows. the first part i want to introduce the background of this research. the second part suggests a simple household choice model .the third part covers the data used in this research. and then, we introduce the empirical results. finally, a simple conclusion is given. 2. introduction -精选财经经济类资料- -最新财经经济资料-感谢阅读- 2 well, lets move on the first part of this topic .the motivation of this work like this. institutional economics posits that agents making decisions on different types of transactions do so in a costly way .for example , farmers deciding sell a particular crop to whom base their decisions not only on the price they expect to receive in each market choice but also on additional costs related to transacting in these markets. i want to use a picture to illustrate it. for example, given some market channels, farmers choices can be regarded as equilibrium between the surplus and the additional costs that related to transacting .especially in developing countries, high-value crop producers fully participate in the market and the transaction cost has been the hard constraint to farmers. furthermore, -精选财经经济类资料- -最新财经经济资料-感谢阅读- 3 farmers market choices can be taken as a choice dilemma of transaction cost and production surplus. consequently, the scientific question of this research is how transaction cost affects planters choices. 3. methodology lets move to the theoretical model of our research. consider a household model in one rotation. in stage 1 , famer needs to allocate the input factors .this process can qbe set into a function like this q? ? q , q means the output farmers decide qto produce .p implies the output price w implies input price and.z: ? is fixed input. once produce what and produce how many are decided, next question to be considered is how much products to be transacted in market. here we use three ccc means how functions to describe this question. the first equation, c ? -精选财经经济类资料- -最新财经经济资料-感谢阅读- 4 ?p , z ? much agricultural products used by famers themselves. p implies the price the cagricultural product,z ?suggests the fluctuation of c. the second equation q ? ? q ? ?c?, q means the amount of agricultural products transacted in q?n?market. the third equationi ? q ?implies the amount exchanged in nth time. in stage 3, farmers will decide to sell the products to whom. chanel js market price is bdecided by an exogenesis price and farmers negotiating power.pij?p* j?bbesides this, we use a matrix to show the net profit of chanel jx ik? ik, ? ? ik ? and then farmers choice can be expressed in a typical choice model exppr?1 exp? k?1 -精选财经经济类资料- -最新财经经济资料-感谢阅读- 5 based on the choice model, another important concept is famers channel choice .here, we set five types .they rank by the market barriers. accordingly, we set a group discrete number to express them. y: dependent variable y=5,means farmer choose brokers. y=1, farmers sell products to consumers directly. 4. data and estimation procedures here, we illustrate the data distribution with this map. according to the agricultural regionalization from department of agriculture, the apple specialization areas in china contain two parts: bo sea area and loess plateau. bo sea area in red color, contains hebei, shandong and liaoning 3 provinces. and loess plateau in green color, contains shanxi, henan, shaanxi and gansu 4 provinces. firstly, we use pps method to get the first stage

prediction model of bus arrival time -精选财经经济类资料- -最新财经经济资料-感谢阅读- 11 the urban public transportation information service system, for the bus arrival time showed on the intelligent electronic station board，is designed to provide accurate and timely information which can help travelers choose transit lines and the shortest paths, can improve the travel efficiency and attract more potential travelers. however, the current bus arrival time prediction model under application cant achieve satisfactory results. this paper analyzes the technology components of the bus arrival time, and builds real- time dynamic models for each component. finally, it adds up all the technology components of the bus arrival time, gets a much more accurate prediction model. keywords electronic station board; bus arrival time; prediction model introduction -精选财经经济类资料- -最新财经经济资料-感谢阅读- 12 1、nowadays, urban public transportation system has attracted the peoples unprecedented attention and experienced a very good development; meanwhile, theory research，system design and implementation of the advanced public transportation systems, as an important part of the intelligent transportation systems ,are being promoted. 2、installing the intelligent electronic station board at the bus stop station for showing the distribution of transit lines related to the station, the distance of the bus belong to some transit line and their prediction arrival time, can help passengers know the location of each bus and determine their travel arrangements. 3、the urban public transportation information service system is an important -精选财经经济类资料- -最新财经经济资料-感谢阅读- 13 part of apts, also reflects the modernization of urban public transportation; it constitutes a part of the modern urban public transportation system, collaborating with the intelligent transit dispatching system, the transit optimization system and the transit evaluation system. technical analysis of bus arrival time 1、the accuracy of the bus arrival prediction time is directly related to the precision of information showed on the intelligent electronic station board. therefore, the accuracy of the next buss arrival prediction time showed on the intelligent electronic station board is a very key indicator. 2、the prediction model of bus arrival time displayed on the intelligent electronic station board need to be improved urgently. -精选财经经济类资料- -最新财经经济资料-感谢阅读- 14 meanwhile, theory research，system design and implementation of the advanced public transportation systems, as an important part of the intelligent transportation systems ,are being promoted. 3、the technology components of the bus arrival time are divided into the following five parts: ? ? ? ? the average travel time through the sections; queuing delay time as a result of the impact of signal control; the time the bus travel through the intersection; stop time at the last few stop stations as a result of the passengers get off and on before the prediction stop station; ? lost time of slow down and speed up because of bus entering and leaving the -精选财经经济类资料- -最新财经经济资料-感谢阅读- 15 stop at the last few stop stations before the prediction stop station. the prediction model of bus arrival time a. the travel time on sections travel time is defined as pure running time on sections, does not contain short delayed time because of traffic signal control, the time for passengers getting on and off on each stop station and the stop time for vehicle technical problems. b. the delay time on stop stations before the prediction stop station the delay time at stop station denotes the lost time when they slow down and speed up because of bus entering and leaving the stop station, the time for opening the bus doors and the time occupied by passengers to get on . c. queuing delay time as a result of the impact of signal control -精选财经经济类资料- -最新财经经济资料-感谢阅读- 16 d. the time the bus travel through the intersection it is presumed that the speed of vehicles travel through kth intersection equals to the average vehicle speed of upstream section and downstream section, then the time the bus travel through the kth intersection equals e. calculating the bus arrival time conclusion ? ? ? ? the average travel time through the sections; queuing delay time as a result of the impact of signal control; the time the bus travel through the intersection; stop time at the last few stop stations as a result of the passengers get off and on before the prediction stop station; ? lost time of slow down and speed -精选财经经济类资料- -最新财经经济资料-感谢阅读- 17 up because of bus entering and leaving the stop at the last few stop stations before the prediction stop station. ? finally, i find my explanation about my major is too professional for my classmates to understand, so i find it is important to make use of examples if i want to make my audience clear. this majors main job is making and optimizing machines. students of this major will learn the theory of machines and build the machine based on the knowledge. in addition, analyzation optimization of the machine is also required in this major, which will make the machine works well. this major deals with the whole plan of the project including investment regulation, risk control, quality and quantity. all of the work makes the plan -精选财经经济类资料- -最新财经经济资料-感谢阅读- 18 goes well and get rich profit. 参加国际学术会议总结 高 兵

-精选财经经济类资料- -最新财经经济资料-感谢阅读- 19 大会共有 600 余篇 poster 展出， 本人的第一作者论文“applicationof structuredexceptionhandlinginsoftware anti-debugging ”被本次大会安排为会议 首日第一个分会场的第一个口头宣读， 充分体现了大会对本论文的重视，作为 本次大会第一个宣读的论文，本论文也 得到了分会场主席和与会专家和学者的 普遍好评并得到很多有益的建议，可谓 收获颇丰。具体内容是： 随着软件产业的快速发展，以反 跟踪技术为核心的软件安全已经成为一 个重要的课题。在与软件解密做着不懈 斗争的同时，软件从业人员不断发现新 的软件反跟踪策略，提出新的软件保护 方案，增强了软件的安全性。 结构化异常处理，是操作系统提 供的用于解决系统软硬件异常的一种机 制，在程序设计中的合理使用可以提高 软件的稳定性、容错性。本文着重探讨 了其在软件反跟踪中的应用。 应用程序正常执行中出现异常时, -精选财经经济类资料- -最新财经经济资料-感谢阅读- 20 操作系统将收集异常发生的原因、类型、 位置等信息，填写相关的数据结构,并从 用户程序转到系统级执行,将控制权交给 系统的异常调度函数。该函数将根据系 统收集的异常信息选择一个异常处理例 程处理异常。用户可定义的异常处理例 程分为两种；一种是线程相关的，一种 是进程相关的:线程相关的异常处理例程,监 视某线程中某段代码是否发生异常，由 于线程是程序执行的最小单位，所以把 异常解决于线程的内部，可以避免该异 常对其它线程的干扰，保证程序的稳定 运行。进程相关的异常处理例程：也称 为筛选器，监视进程中所有线程发生的 异常，做进程退出前的清理工作。 异常处理流程是指运行在 win32 系统中的程序通常包含多个线程，而每 个线程都会安装各自的异常处理例程； 除此之外，程序中可能存在一个全局性 的异常处理例程；再者，如果进程被调 试的话，调试进程也相当于一个异常处 理例程。当异常发生时，系统将根据异 -精选财经经济类资料- -最新财经经济资料-感谢阅读- 21 常类型选择一个异常处理例程来处理异 常，正常情况下，系统进行异常处理的 流程为： 系统首先判断异常是否应发送给 目标程序的异常处理例程。如果应该发 送，并且目标程序正在被调试则系统 挂起程序；如果程序没有被调试或者调 试器未能处理异常，系统继续查找是否 安装了线程相关的异常处理例程。如果 已经安装，系统就把异常发送给 seh 处 理例程。每个线程相关的异常处理例程 可以处理或者不处理这个异常，如果它 不处理并且安装了多个线程相关的异常 处理例程可交由 链起来的其他例程处理；如果这 些 seh 处理例程均不处理异常，且程序 处于被调试状态，操作系统会再次通知 调试器；如果程序未处于被调试状态或 者调试器没有能够处理，并且程序调用 setunhandledexceptionfilter 函数安装了 进程相关的异常处理例程的话，系统转 向对它的调用；如果没有安装进程相关 -精选财经经济类资料- -最新财经经济资料-感谢阅读- 22 的异常处理例程或者它没有处理这个异 常，系统会调用默认的异常处理例程， 通常显示一个对话框，用户可以选择 “关闭”或者可以将程序附加到调试器的 “调试”按钮。如果没有可以附加的调试 器或调试器也不处理，系统就对线程异 常处理句柄进行展开做最后的清理工作， 最终调用 exitprocess 终结程序。通过对 系统异常处理流程分析可知，当应用程 序执行过程中发生异常时，系统可在三 个层次上完成异常处理：调试器、进程、 线程。线程层次的异常处理即 seh，能 够准确定位异常的信息，更加灵活、隐 蔽的实现反跟踪的功能，是本文研究的 主要方面。下面深入分析 seh 的工作原 理。 系统级处理机制，seh 作为系统 内部处理异常的一种机制，其工作主要 在系统级完成，因此掌握系统内部异常 处理的工作原理是研究基于 seh 的软件
