模拟国际会议演讲稿

1. Introduction Thank you very much. Mr. Jiao, for your kind introduction. Ladies and gentlemen, Good afternoon! My name is Lijia, came from Harbin Engineering University. I am honored to have been invited to speak at this conference. Before I start my speech, let me ask a question. Do you know what can affect the properties of foam concrete? Do yo

Today, my topic is about Inﬂuence of ﬁller type on the properties of foam concrete. I want to share our interesting research result on reinforced concrete frame with you. The content of this presentation is divided into 4 parts: In section 1, I will introduce what is the foam concrete. In section 2, I will talk about Parameters investigated and mix compositions. In section 3, I will give Eﬀect of water–solids ratio on design density. And finally, I will make a conclusion. 2. Body Section 1: the foam concrete Now, I will introduce the foam concrete. Pre-formed(成型的) foam concrete is manufactured(加工)by adding foam, prepared by aerating(充气)a foaming agent solution, to cement paste or cement mortar(灰

浆). The composition(合成物), physical properties(性能)and uses of foam concrete were discussed in detail(详细的)by Valore, Short and Kinniburgh, Rudnai and Taylor. Although several investigations have been conducted on the properties of foam concrete, most of them deal with cement–sand mixes, neat cement paste with or without partial replacement(局部替换)using admixtures(掺合料). Few studies report on the inﬂuence of ﬁller type on the properties of foam concrete. By using ﬂy ash(粉煤灰)as ﬁller (ﬁne aggregate细骨料) instead of sand, the high volume(体积)utilization(利用)of ﬂy ash becomes possible可能, thus providing a means of eco-nomic(经济)and safe disposal(处理)of this waste product. Comparison(比较)of strength of air-cured foam concrete made with cement-sand and cement–ﬂy ash for masonry(砌体结构)by Durack and Weiqing show that for products of comparable density(比较密度), mixes with ﬂy ash as ﬁne aggregate in place of sand gave relatively higher strength. Section 2: Parameters(参数)investigated and mix compositions(组成成分)

So much for the foam concrete, now I will move on to Parameters(参数)investigated and mix compositions. As the experimental programme(实验程序)was aimed at studying the eﬀect of the ﬁllers on the properties like density(密度), ﬂow behaviour(流动特性), water absorption(吸水率)and strength of foam concrete, the following mixes

were investigated by keeping the basic ﬁller–cement ratio constant(恒定不变)at 1:1 by weight. The foam required for three densities(密度)of foam concrete viz. 1000, 1250, 1500 kg/m3 were arrived at as per ASTMC 796-97. In the cement–sand–ﬂy ash mixes 50% of the sand is replaced with ﬂy ash and in the cement–ﬂy ash mixes all the sand is replaced with ﬂy ash. Section 3: Eﬀect of water–solids ratio(水砂比率)on design density That bring me to Eﬀect of water–solids ratio(水砂比率)on design density. I think this part is the most important in my presentation, I will explain in detail. As the foam is added to the wet foam concrete mix, the consistency(稠度) of the wet mix is very important to get the design density. Fig. 2(a) and (b) show the variation of density ratio(密度变化率)(measured fresh density divided(分离)by design density) with water–solids ratio for mixes with diﬀerent ﬁller type for each of the design densities, viz., 1000 and 1500 kg/m3, respectively(分别地). It is observed that at lower water–solids ratios, i.e., at lower consistency, the density ratio is higher than unity(个体). The mix is too stiﬀ(严格地)to mix properly thus causing the bubbles(气泡)to break during mixing resulting in increased density. At higher water–solids ratios there is also an increase in density ratio as higher water contents make the slurry(泥浆)too thin to hold the bubbles resulting in segregation(分离)of the foam from the mix along with segregation of the mix itself thus causing

an increase in measured density. Therefore, as shown in Fig. 2(a) and (b), a density ratio of unity or nearly unity is achieved only at a particular consistency. This consistency requirement for the mix before adding foam to it can be expressed in terms of water–solids ratio. It is also observed that the water–solids ratio required to obtain a density ratio value of one, depends on the ﬁller type.

Section 4: Conclusion The conclusions drawn from this study and summarized below are applicable(合适的)to the characteristics of the materials(材料特性)used and the range of parameters(参数范围)investigated: (i) the consistency of pre-formed foam concrete mixtures (deﬁned as the water–solids ratio for achieving the target(目标)density) mainly depends on the ﬁller type, i.e., relatively higher for mixes with ﬂy ash as ﬁller compared to mixes with sand; (ii) the ﬂow behaviour mainly depends on the foam volume and as the foam volume increases the ﬂow decreases. For a given density, foam concrete with ﬂy ash as ﬁller showed relatively(相当的) higher ﬂow values; (iii) for a given density, an increase in ﬂy ash content of the mix results in increased strength. In comparison(比较)to cement–sand mixes, cement–ﬂy ash mixes showed relatively higher water absorption(吸收). That’s all. Thank you! Are there any questions?

The picture on this slide is

So much for ......, now I will move on to...... This slide shows the calculation result

As we know, the target user usually has taken a list of courses rather than a course, so we need to extent our probability calculation formulars. For example, suppose T={a,b}, Pr[x﹁T] the probability x occurs without either an a or b preceding it; Pr[x﹁T] the probability x occurs without either an a or b following it. This probability can be calculated exactly. So how to calculate it?

That bring me to Recommendation Algorithms. I think this part is the most important in my presentation, I will explain in detail.

In conclusion, we proposed a novel precedence mining model, developed

To sum up, first, I introduced the motivation and the outline of work; second, I gave the definition of precedence mining model; third, I described some new recommendation algorithms using precedence information; forth, I showed our experimental results to compare the new algorithms with traditional ones. Finally, I made a conclusion of our work..

That’s all. Thank you! Are there any questions?

Apart from our faculty and students, Most of the delegates and guests are prestigious experts and scientists, who are related in these fields from all over the world. With many significant achievements, they are the most dynamic leaders in the movements of the science and technology.

ICNC-FSKD is a premier international forum for scientists and researchers to present the state of the art of data mining and intelligent methods inspired from nature, particularly biological, linguistic, and physical systems, with applications to computers, circuits, systems, control, communications, and more. This is an exciting and emerging interdisciplinary area in which a wide range of theory and methodologies are being investigated and developed to tackle complex and challenging problems. As the host, I would like to take this opportunity to give you a general introduction about our school.. Xiamen University(XMU), founded in 1921 ,is the first university in China founded by overseas Chinese. Before 1949, it was named University of Amoy. The school motto: "Pursue Excellence, Strive for Perfection (自强不息, 止于至善)". Now this university ranked the 13th in China, which is in the front rank in China and maintain the top 20 ranking in china. This university is one of the comprehensive universities directly affiliated with the Education Ministry, is located in the city of Xiamen in Fujian Province. In 1995 it was included in the list of the “211 Project” for the state key construction; in 2000 it became one of China’s higher-level universities designated for the state key construction of the “985 Project”.

For this conference, we are following the agenda here. The meeting is supposed to last for three days，and to be separated into two parts. To begin with , we’ll invite some representatives from our guests to give lectures about their latest researches and reports on the issue, and then we will have some symposiums. During the conference we are pleased to be your guide to this city. If anything needed, don’t hesitate to contact us. We believe by our collaboration we are sure to make this gathering a consummation. And finally I wish you an unforgettable and prefect experience here.

Thanks!
