Lu Jiaxi (mathematician)
Lu Jiaxi (; June 10, 1935 – October 31, 1983) was a self-taught Chinese mathematician who made important contributions in combinatorial design theory. He was a high school physics teacher in a remote city and worked in his spare time on the problem of large sets of disjoint Steiner triple systems. Biography Background Lu Jiaxi was born in a poor family in Shanghai. His father was a seller of soy sauce concentrate. His parents had four children, but the three older children all died early from illness, and Lu Jiaxi was the only surviving child. When he was in junior middle school, his father died from an illness that the family could not afford to treat, so he started working after finishing junior middle school in 1949 to earn a living. He served an apprenticeship at an automobile hardware firm in Shanghai. In October 1951, he was admitted to a statistics training course in Shenyang offered by the administration for electrical equipment industry of Northeast China, and he fi ...

Hard Seat
The Hard seat () or Semi-cushioned seat, abbreviated YZ, is the cheapest class of seating in China Railway. It is available on non-high-speed trains. The name of Hard seat derives comes from the hard, wooden seats in the Mao era on regular passenger trains. Modern "hard seats", however, are upholstered. There are several different tickets and ticket prices that can be obtained. Each carriage provides the most basic services common to all Chinese trains, namely toilets, wash basins and a boiling water dispenser. This demonstrates the importance of the ticket prices and the ability for them to change over time. Compared to soft seat, hard seat carriages have more seats per row (2+3 vs. 2+2) and are usually more crowded, and people without seats may stand in hard seat carriages. Coaches The coaches current in use include: * YZ-21 (no air conditioner) * YZ-22 (no air conditioner) * YZ-22B (no air conditioner) * YZ-25B (no air conditioner) * YZ-25G * YZ-25K * YZ-25T * YZ- ...

Kang Bed-stove
The ''kang'' (; Manchu: ''nahan'', kk, кән) is a traditional heated platform, 2 metres or more long, used for general living, working, entertaining and sleeping in the northern part of China, where the winter climate is cold. It is made of bricks or other forms of fired clay and more recently of concrete in some locations. The word ''kang'' means "to dry". Its interior cavity, leading to an often-convoluted flue system, channels the hot exhaust from a firewood/coal fireplace, usually the cooking fire from an adjacent room that serves as a kitchen, sometimes from a stove set below floor level. This allows a longer contact time between the exhaust (which still contains much heat from the combustion source) and (indirectly) the inside of the room, hence more heat transfer/recycling back into the room, effectively making it a ducted heating system similar to the Roman hypocaust. A separate stove may be used to control the amount of smoke circulating through the ''kang'', main ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Block Design
In combinatorial mathematics, a block design is an incidence structure consisting of a set together with a family of subsets known as ''blocks'', chosen such that frequency of the elements satisfies certain conditions making the collection of blocks exhibit symmetry (balance). They have applications in many areas, including experimental design, finite geometry, physical chemistry, software testing, cryptography, and algebraic geometry. Without further specifications the term ''block design'' usually refers to a balanced incomplete block design (BIBD), specifically (and also synonymously) a 2-design, which has been the most intensely studied type historically due to its application in the design of experiments. Its generalization is known as a t-design. Overview A design is said to be ''balanced'' (up to ''t'') if all ''t''-subsets of the original set occur in equally many (i.e., ''λ'') blocks. When ''t'' is unspecified, it can usually be assumed to be 2, which means th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Soochow University (Suzhou)
Soochow University (), also known as Suzhou University, is a public university in Suzhou (Soochow), China. Its root can be traced to the original Soochow University (東吳大學) founded by Methodists in 1900, which was later split and merged with a couple of institutions. It is part of the Double First Class University Plan held by the Ministry of Education for developing world-class universities. It only admits those who score at top 5% in the National College Entrance Examination of China, thus is regarded as a relatively selective university. The School of Humanities, School of Textile and Clothing Engineering, School of Chemistry, Chemical Engineering and Materials Science, and School of Medicine are the university's most distinguished schools. History The original Soochow University () was founded by Methodists in Suzhou in 1900 as a merger of three existing institutions: the Po-hsi Academy, the Kung-hsiang Academy, and the Chung-hsi Academy.
