Demands on real-time kernels increase every year: as applications grow larger and become more complex, real-time kernels must give short and predictable
در سیستم های کنترل نظارتی و اکتساب داده (scada)، انتقال اطلاعات مابین rtuها و مرکز کنترل به د لایل مختلفی از جمله، محدودیت سرعت انتقال داده، مسافت بین rtu و مرکز کنترل، ترافیک شبکه ارتباطی و نیز زمان های مورد نیاز برای مدولاسیون، دی مدولاسیون و پردازش اطلاعات، با تأخیر همراه است. ازطرفی، در سیستم های صنعتی، خصوصاً شبکه های قدرت، لازم است که داده های اندازه گیری و فرمان های کنترلی، به صورت بلادرن...
Supply disruption such as overloading will cause interruptions of electricity supply to customers. The technicians have to manually locate the fault point and this tedious work may last for extended periods of time. The other reasons are the lack of use of efficient tools for operational planning and advanced methodology for quick detection of fault, isolation of the faulty section and service ...
The communication infrastructure of the modern Supervisory, Control and Data Acquisition (SCADA) system continues to enlarge, as hybrid High Voltage Direct Current (HVDC)/Alternating (AC) networks emerge. A centralized SCADA faces challenges meet time requirements two different power topologies, such employing toolboxes for both grids. This paper presents a HVDC/AC network. In addition, case st...
The objective of this study was to re-evaluate our previously published technique of estimating total physically separable internal fat (IFAT) in beef cattle using real-time ultrasound (RTU) and carcass measurements from live animals by including more breed types and genders under different management scenarios. We expanded the original database and performed additional analyses. The database w...
The distribution of non-ant arthropods was examined in 40 urban habitat fragments in coastal San Diego County, California, USA, to look for effects of fragmentation, proximity to developed edge, and the non-native Argentine ant (Linepithema humile). Arthropods were sampled with pitfall traps and by vacuum sampling from California buckwheat shrubs (Eriogonum fasciculatum). Individual arthropods ...
Minute intestinal flukes, Haplorchis taichui and H. pumilio, belong to the family Heterophyidae (Trematoda: Platyhelminthes), which have been studied very limited, especially molecular markers of mitochondrial genomes (mtDNA) ribosome transcription units (rTU or rDNA). We obtained complete genome coding part unit pumilio Vietnam. Nucleotide amino acid data were compared between Metagonimus yoko...
