A Casual [Causal] Relationship Between Building Maintenance Market And Gdp: Hong Kong Study, Yong-Tao Tan, Liyin Shen, Craig Langston
A Casual [Causal] Relationship Between Building Maintenance Market And Gdp: Hong Kong Study, Yong-Tao Tan, Liyin Shen, Craig Langston

Purpose: The purpose of this paper is to examine the causal relationship between the building maintenance market and GDP in Hong Kong. Design/methodology/approach: The Granger causality test is used to investigate the lead-lag relationships between the maintenance and repair work and GDP in Hong Kong. With regression analysis, the future trend of the maintenance market is forecasted. Findings: The results show that the growth of the economy will lead to the growth of the maintenance market, not vice-versa. And the building maintenance market in Hong Kong will keep increasing with the economy growth. Originality/value: This paper shows that the growth …

Haagerup's inequality for convolvers on free groups may be interpreted as a result on A1 buildings, i.e. trees. Here are proved analogous inequalities for discrete groups acting freely on the vertices of A1 x A1 and A2 buildings. The results apply in particular to groups of typerotating automorphisms acting simply transitively on the vertices of such buildings. These results provide the first examples of higher rank groups with property (RD).

Triangle Buildings And Actions Of Type Iii 1/Q2, Jacqueline Ramagge, Guyan Robertson
Professor Jacqui Ramagge
We study certain group actions on triangle buildings and their boundaries and some von Neumann algebras which can be constructed from them. In particular, for buildings of order q ≥ 3 certain natural actions on the boundary are hyperfinite of type III1/q2.

Cohomology Of Buildings And Finiteness Properties Of An-Groups, Jacqueline Ramagge, Wayne Wheeler

Borel and Serre calculated the cohomology of the building associated to a reductive group and used the result to deduce that torsion-free S-arithmetic groups are duality groups. By replacing their group-theoretic arguments with proofs relying only upon the geometry of buildings, we show that Borel and Serre's approach can be modied to calculate the cohomology of any locally nite ane building. As an application we show that any nitely presented e An-group is a virtual duality group. A number of other niteness conditions for e An-groups are also established.

Application Of A Fuzzy Controller To Seismically Excited Nonlinear Buildings, Mohammed Al-Dawod, Bijan Samali, Kenny Kwok, Fazel Naghdy
Professor Fazel Naghdy
Focuses on the benchmark control problems for seismically excited nonlinear buildings defined by Ohtori et al. (2000). This benchmark study focuses on three typical steel structures, 3-, 9- and 20-storey buildings designed for the SAC project for Los Angeles in the California region. The first stage of applying the fuzzy controller to this benchmark study for the 3-storey building is reported. The main advantage of the fuzzy controller is its inherent robustness and ability to handle the non-linear behaviour of the structure. This benchmark study is based on a number of evaluation criteria and control constraints and these limitations are …
