Control and Filtering for Discrete Linear Repetitive Processes with H infty and ell 2--ell infty Performance
Repetitive processes are characterized by a series of sweeps, termed passes, through a set of dynamics defined over a finite duration known as the pass length. On each pass an output, termed the pass profile, is produced which acts as a forcing function on, and hence contributes to, the dynamics of the next pass profile. This can lead to oscillations which increase in amplitude in the pass to pass direction and cannot be controlled by standard control laws. Here we give new results on the design of physically based control laws for the sub-class of so-called discrete linear repetitive processes which arise in applications areas such as iterative learning control. The main contribution is to show how control law design can be undertaken within the framework of a general robust filtering problem with guaranteed levels of performance. In particular, we develop algorithms for the design of an H? and dynamic output feedback controller and filter which guarantees that the resulting controlled (filtering error) process, respectively, is stable along the pass and has prescribed disturbance attenuation performance as measured by and – norms

Study of carbonation rate of synthetic C-S-H by XRD, NMR and FTIR
Supplementary cementitious materials (SCMs) like fly ash (FA) and blast furnace slag (BFS) are broadly used in concrete to replace part of the Ordinary Portland Cement (OPC) because of both economic and environmental issues. In concrete blended with SCMs, C-S-H with different C/S ratios, formed from the hydration and pozzolanic reactions of blended cement, is the major calcium-bearing phases which reacts with CO2 during carbonation. Therefore, it is important to study the carbonation rate of different C-S-H phases. In this paper, the C-S-H phases (C/S ratio: 0.66 to 2.0) were synthesized and used for accelerated carbonation testing. Synthetic C-S-H phases with different C/S ratios were identified by X-ray diffraction and 29Si nuclear magnetic resonance (NMR). Carbonation rate and products of different C-S-H phases are also determined. The results show that C-S-H (I) phases with different target C/S ratio (lower than 1.40) were synthesized in the mix solution of lime and fume silica. The portlandite appears in the products when the designed C/S ratio is higher than 1.40 under this synthetic condition. C-S-H with lower C/S ratio is decomposed faster than that with a higher C/S ratio. After exposition to the accelerated carbonation condition for three days, in this research, the C-S-H phases with different C/S ratio were all fully decomposed to CaCO3 and silica gel.</p
Formation and stability of point defects in monolayer rhenium disulfide
Abstract: Recently, rhenium disulfide (ReS2) monolayers were experimentally extracted by conventional mechanical exfoliation technique from as-grown ReS2 crystals. Unlike the well-known members of transition metal dichalcogenides (TMDs), ReS2 crystallizes in a stable distorted-1T structure and lacks an indirect to direct gap crossover. Here we present an experimental and theoretical study of the formation, energetics, and stability of the most prominent lattice defects in monolayer ReS2. Experimentally, irradiation with 3-MeV He+2 ions was used to break the strong covalent bonds in ReS2 flakes. Photoluminescence measurements showed that the luminescence from monolayers is mostly unchanged after highly energetic a particle irradiation. In order to understand the energetics of possible vacancies in ReS2 we performed systematic first-principles calculations. Our calculations revealed that the formation of a single sulfur vacancy has the lowest formation energy in both Re and S rich conditions and a random distribution of such defects are energetically more preferable. Sulfur point defects do not result in any spin polarization whereas the creation of Re-containing point defects induce magnetization with a net magnetic moment of 1-3 mu B. Experimentally observed easy formation of sulfur vacancies is in good agreement with first-principles calculations
The Bible between Literary Traditions: John C. H. Wu’s Chinese Translation of the Psalms
In the history of Chinese Bible translation, the Psalms have been a privileged site for the encounter between biblical thinking, poetics, and Chinese classical literature. This encounter was initiated by the translators of the Delegates’ Version, followed by John Chalmers, and outstandingly represented in particular by John C. H. Wu吳經熊. In his version of the Psalms, underpinned by his cultural stance of “beyond East and West”, Wu borrows numerous Chinese idioms and popular verses and transposes Chinese traditions from Confucianism, Buddhism, and Daoism. Specifically, Wu’s rendition inaugurates an intertextual dialogue between the Psalms and Shijing, involving the disciplines of both comparative literature and comparative scripture at the same time. By adapting various Chinese classical poetry styles for his version of the Psalms, Wu transforms their spiritual traditions and broadens their representation spaces by injecting a Judeo-Christian spirit. Relocating the biblical texts among multifarious Chinese literary traditions, Wu’s translation of the Psalms achieves a deep interaction between the Bible and Chinese culture, provokes questions, and provides insights regarding the relation between biblical theology and intercultural poetics

Functorial Decompositions of Looped Coassociative Co-<i>H</i> Spaces
AbstractSelick and Wu gave a functorial decomposition of Ω∑X for path-connected, p-local CW-complexes X which obtained the smallest nontrivial functorial retract Amin(X) of Ω∑X. This paper uses methods developed by the second author in order to extend such functorial decompositions to the loops on coassociative co-H spaces.</jats:p
