On the Li--Zheng theorem
Full text linkBy the well-known I.Kotlarski lemma, if , , and are
independent real-valued random variables with nonvanishing characteristic
functions, and , then the distribution of
the random vector determines the distributions of the random
variables up to shift. Siran Li and Xunjie Zheng generalized this
result for the linear forms and
assuming that all have first and second
moments, and are identically distributed, and ,
satisfy some conditions. In the article, we give a simpler proof of this
theorem. In doing so, we also prove that the condition of existence of moments
can be omitted. Moreover, we prove an analogue of the Li--Zheng theorem for
independent random variables with values in the field of -adic numbers, in
the field of integers modulo , where , and in the discrete field of
rational numbers.Comment: 15 page
[[alternative]]Professor Li Zheng-Zhi research achievements of Li Bai's poems
No full text[[abstract]]李正治教授致力於李白研究數十年，雖然相關著作不多，但形諸文字的論著卻是篇篇擲地有聲。從早期的〈「下江陵」的聯想與李白的江湖行〉到〈李白的「釣鼇」意識〉等，都是具有獨創性的見解之作。本文論述採逆向的研究進程：先整體性分析李正治教授的詩歌研究文本，再從這些資料中探進李教授的詩歌觀念，接著進入其李白研究的核心成就－釣鼇意識。最後，分析李教授對李白提出的文學史定位－｢兩漢六朝詩的集大成者」之依據。希望透過本文，能夠完整的呈現李正治教授的李白詩研究成果。[[abstract]]Professor Li Zheng-Zhi committed Li Bai decades of research, although related works much, But it is very important works of each . From the early "Go Gangneung” Lenovo and Li Bai to go traveltoLi Bai's “Diaoao” consciousnessare made with a view of originality. This paper discusses research progress reverse mining : first holistic analysis of Poetry Professor Li Zheng-Zhi text, and further study of his poetry from these data views , then re-enter the core of their research achievements－Li Bai's “Diaoao”consciousness. Finally, analysis of Li Bai position he made history in literature－" Han and Six Dynasties master of poetry ." Basis.

Water Injection of a Small Engine
No full textThe main objective of this project is to create a water injection system for a small air cooled engine. The design involves a 6.5 hp 4 stroke engine, with a displacement of 196cc. The design intent is to design an injection system to inject a water/methanol mixture at a given rate to assist the air cooling of the engine and increase the density of the intake air by decreasing the temperature. These systems are common on high performance, large 4 stroke water cooled engines in cars. Some benefits of using a water/methanol mixture is that it cools the intake air and reduces the emission of NOx from combustion. Our design is focused on creating an intake tube that will be easily bolted onto the intake of any small engine, and an injection system to inject the water mist into the tube. The solution to be injected is a water mist, which will cool the intake charge and cause the air to be denser. There will be two temperature sensors, one for the incoming air and one for the treated air with the mixture. Due to our budget constraint of $400, there will not be a NOx sensor on the exhaust to measure the emissions. In order to use the NOx emission reduction, the intake charge must have a sizable temperature reduction in the intake tube before proceeding into the engine. Our simplistic design will be able to record the temperature difference between the incoming air and treated water/methanol vapor mixture. The design also incorporates a small nozzle of size 0.003” for the mixture passageway into the tube, limiting the flow from the electric pump to prevent too much flow into the engine. The pump, which is a 12v DC powered pump, will have a potentiometer to adjust the resistance and therefore adjust the flow from the pump into the system
