This study proposes a way of designing reliable voltage controller for buck DC/DC converter in which the terminal attractor approach is combined with an enhanced reaching law-based Fast Terminal Synergetic Controller (FTSC). The proposed scheme will overcome chattering phenomena constraint existing Sliding Mode Controllers (SMCs) and issue related to indefinite time convergence traditional (SCs...
The extend to which geometrical effects contribute to the production and suppression of the J/ψ and qq minijet pairs in general is investigated for high energy heavy ion collisions at SPS, RHIC and LHC energies. For the energy range under investigation, the geometrical effects referred to are shadowing and anti-shadowing, respectively. Due to those effects, the parton distributions in nuclei de...
Thus the comparison ends in a manner fully as satisfactory as in [I] and [2]. The proof uses essentially the same method of acyclic models as was used in those papers. A standard (i.e., functorial) complex for each theory is constructed and the hypotheses of the theorem of acyclic models of [2] are shown to be satisfied, from which chain equivalence of these complexes follows. Here the standard...
This article adopts the concept of prosumption in order to better understand array contemporary food sustainability transition initiatives that often come under umbrella term Alternative Food Networks (AFNs). AFNs have developed parallel prosumption, which is significant because are oriented towards localized and direct relationships between producers consumers, while explains hybridization con...
This research examines the extent to which a Farm-to-Table restaurant prompted social and ecological changes in food system. Chefs restaurants are uniquely positioned both generate consumer interest certain foods motivate farmers grow such products. Despite their central role Alternative Food Networks (AFNs), influence of on farming practices re-localization sourcing is under-explored. In this ...
Abstract Community-supported agriculture (CSA) is an alternative way of supplying food based on direct interaction between producers and consumers. As network (AFN) a form civic agriculture, it considered more sustainable production consumption compared to the conventional system. The number CSA initiatives has been increasing in last few decades worldwide parallel growing scholarly debates abo...
BACKGROUND Human chorionic gonadotropin/luteinizing hormone (hCG/LH) function in the male is mediated by the LH receptor (LHR) and is crucial for the normal development of internal and external genitalia. We report a 46, XY patient who presented at the age of 16 with a female phenotype and delayed puberty. Gonads were located bilaterally in the inguinal canal, removed surgically and showed hypo...
This article estimates the frequency of cardiovascular (CV) events that occurred after diagnosis in a large Spanish cohort of patients with systemic lupus erythematosus (SLE) and investigates the main risk factors for atherosclerosis. RELESSER is a nationwide multicenter, hospital-based registry of ss-sectional study. Demographic and clinical traditional risk factors, and CV events were s defin...
Since the definition of the Geocentric Datum of Australia in 1994 (GDA94), Australia has had a GPS continuously operating reference station (CORS) network for datum maintenance. The Australian Fiducial Network (AFN) now comprises eight geologically stable, geodetic quality GNSS CORS stations which also contribute to the Australian Regional Geodetic Network and the International GNSS Network. In...
