This paper presents H∞ control problem for input-delayed systems. A neutral system approach is considered to the design of PD controller for input delay systems in presence of uncertain time-invariant delay. Using this approach, the resulting closed-loop system turns into a specific time-delay system of neutral type. The significant specification of this neutral system is that its delayed coeff...

this paper proposes a novel robust control scheme based on delay-dependent h∞for unified power quality conditioner (upqc) in a microgrid under the influence of the delay and parameter uncertainties. a new upqc model considering the effects of the delay and parameter uncertainties is established. then, the h∞ controller is designed based on the cone complementarity linearization (ccl) algorithm....

Three test-plot series have been performed to gather information on runoff of sulfonamides from manured arable and grassland after sprinkler irrigation. To prepare test slurries with defined aged residues, liquid bovine manure was fortified with sulfadiazine, sulfadimidine, and sulfamethoxazole and stored short-term. After test-slurry application, the arable land was treated by soil cultivation...

Objectives—A prospective cohort study was initiated to clarify whether the current level of exposure to carbon disulphide (CS2) is low enough to prevent occurrence of subclinical health impairments or to ameliorate health eVects due to past high exposure. This paper describes the eVects of exposure to CS2 on the nervous and endocrine systems, and the subjective symptoms in a baseline observatio...

Assay of free and acid labile carbon disulphide (free and total CS2 respectively) in human blood was performed by gas chromatography/spectrometry. The method used a large dynamic head space volume and a "cryogenic trap". Blood CS2 concentration was measured in 42 subjects not occupationally exposed to CS2 (group A) and in 11 alcoholic subjects (group B) treated with disulfiram. Free CS2 concent...

Records of blood pressure and body weight of CS2 workers were analyzed in relation to the levels of CS2 exposure at a Japanese rayon-producing fac tory. A cohort of 46 CS2 workers who had later been transferred to non-CS2 jobs showed first a statistically significant rise, which was then followed by two consecutive episodes of statistically significant falls in systolic blood pressure. These ep...

On 1 June 2021, a heavy rainstorm hit the coast of South China (148.6 mm in h, 361 over 12 h). The storm process was successively affected by two convective systems (CSs). initial convection CSs occurred at similar location; however, they subsequently showed different evolution characteristics. Based on multi-source data, including dual-polarimetric radars, wind profiling sounding, and automati...

Carbon disulfide (CS2) has been historically associated with the production of rayon, cellophane, and carbon tetrachloride. This study identifies multiple mechanisms by which CS2 contributes to the formation of CO2 in the atmosphere. CS2 and other associated sulfide compounds were found by this study to be present in emissions from unconventional shale gas extraction and processing (E&P) operat...

In the title compound (systematic name: 4,4'-{[2-(5,6-di-hydro-[1,3]di-thiolo[4,5-b][1,4]dioxin-2-yl-idene)-1,3-di-thiole-4,5-di-yl]bis-(sulfanedi-yl)}di-benzoic acid 0.25-hydrate), C22H14O6S6·0.25H2O, the tetra-thia-fulvalene (TTF) core adopts a boat conformation, where the central S2C=CS2 plane makes dihedral angles of 31.34 (4) and 26.83 (6)°, respectively, with the peripheral S2C=CS2 and S2...
