The architectural design of Wireless Sensor Networks (WSNs) for the Industrial Internet Things (IIoT) applications requires careful planning and selection an appropriate operational strategy. Harmonization standards is crucial to ensure easier certification commercialization IIoT solutions. ongoing research activities are directed toward designing agile, reliable, secure transmission technologi...

Subclinical hypocalcemia (SCH) affects many high-producing dairy cows in the postpartum period. Recent work has shown that experiencing prolonged or delayed SCH are at increased risk for disease and produce less milk than a transient reduction normal concentrations of plasma Ca following parturition. Our objective was to determine association between different dynamics with pre- dry matter inta...

IEEE 802.15.4e time-slotted channel hopping (TSCH) is one of the most reliable resources Industrial Internet Things (IIoT). TSCH operates on slot-frame structure consisting multiple channel-offsets and slot-offsets. It gaining acceptance due to its simple architecture consume low power in industrial applications. The performance mainly dominated by media access control (MAC) mechanism, which co...

To provide wireless coverage in challenging industrial environments, IEEE802.15.4 Time-Slotted Channel Hopping (TSCH) presents a robust medium access protocol. Using multiple Physical Layers (PHYs) could improve TSCH even more these heterogeneous environments. However, only defines one fixed-duration timeslot structure allowing packet transmission. PHYs with various data rates therefore does no...

چکیده: استاندارد 802.15.4e برای افزایش قابلیت اطمینان به هنگام انتقال بسته­ها در زیرلایه کنترل دسترسی  و برای استفاده در شبکه­های کم توان و مستعد خطا نظیر شبکه­های حسگر بی­سیم ارائه شده است. امکان استفاده از کانال­های متعدد غیرهمپوشان در این استاندارد، احتمال رخداد تصادم بین فرستنده­ها را کاهش می­دهد که این نیز به­نوبه خود باعث افزایش کیفیت سرویس در شبکه و بـالاخـره کاهش مصرف انرژی می­شود. مکان...

Abstract New thiosemicarbazone (TSC) ligands, AMT-C N-TSCH (L1), N-TSC(CH3) (L2), CIN-C (L3) and (L4) (AMT = 2-acetyl-5-methylthiophene, TSCH = thiosemicarbazide, TSC(CH3) = 4-methyl-3-thiosemicarbazide, CIN = cinnamaldehyde) were synthesized by condensation reaction. The reaction of [PdCODCl2] with the ligands L1, L2 L4in ratio 1:1 yielded complexes [Pd(L1)Cl] (C1), [Pd(L2)Cl2] (C2), [Pd(L4)2C...
