“…The energy-delay trade-off is investigated for timer-based coalescing in [8] and for size-based coalescing in [25]. Furthermore, the authors of [26] propose an analytical model for byte-based coalescing which terminate the LPI state when the accumulated workload is above a threshold. Most analytical models developed for 10GBASE-T consider the joint use of time and size based coalescing [14], [20], [27], [28].…”

Frame coalescing is a well-established technique which manages the low power idle (LPI) mode supported by energy efficient Ethernet (EEE) interfaces. Generally, this technique enables EEE interfaces to remain in the LPI mode for a certain amount of time upon the arrival of the first frame (timer-based coalescing), or until a predefined amount of traffic accumulates in the transmission buffer (size-based coalescing). In this paper, we propose a novel open-loop dynamic coalescing technique that is based on model predictive control (MPC) and queuing theory. In contrast with the conventional timer-based coalescing, the proposed method enables the update of the timer parameter repeatedly throughout the duration of the LPI mode of a single coalescing cycle by taking into account the arrival instant and size of the frames waiting in the buffer. Two different methods, namely MPC-mean and MPC-tail, are proposed which attempt to minimize the energy consumption of the Ethernet link under constraints on mean and tail of the queue waiting time, respectively. The effectiveness of the proposed dynamic MPCbased coalescing algorithms are validated using simulations with synthetic and actual traffic traces.

“…Solar and electrical heat gain and Q EM do not change significantly with rain, however the conductor heat losses parameters specifically convective heat loss reacts differently during rainy days. Rain droplets reduce viscosity of air and increase air mass of air [11]. Impact of rain was touched on by the work done by pioneers like Murray Davies, whose work influenced the formation of IEEE 738, Murray found that convective cooling increases by 50% when conductor is wet [12].…”

The worldwide fast pace at which wind power generation technology and its drive train is growing has increased the demand for wind farm connection into the power grid. The UK target of increasing wind energy contribution coupled with the excellent wind profile has led to growing demand for distribution and transmission connection points. The main obstacle hindering large scale of integration of the wind energy is the thermal capacity limits of the existing transmission lines infra structure. Thermal capacity computation techniques are based on heat balance equation stipulated in IEEE 738. This paper analyses the heat balance equation and proposes the addition of new variable to the set of heat balance equations, discusses the economic aspects of dynamic line ratings. The main objective of this paper is to mathematically integrate the effect of precipitation rate into the heat balance equation, based on empirical study conducted. Index Terms-Ampacity of bare power lines, dynamic ratings, ruling span of transmission line, temperature overshoot effect and thermal time constant. I.
