Energy is a constrained resource in mobile wireless networks. In such networks, communication takes place over fading channels. By varying the transmission rate and power based on the current fading level, a user in a wireless network can more efficiently utilize the available energy. For a given average transmission rate, information theoretic arguments provide the optimal power allocation. Ho...

the voltammetric behaviour of sulfadoxine (sdn) was studied at a glassy carbon electrode in 0.2 m phosphate buffer solutions using cyclic, differential-pulse (dpv) and square wave voltammetry (swv). the dependence of the current on ph, concentration, and scan rate was investigated to optimize the experimental conditions for the determination of sdn. the oxidation process was shown to be diffusi...

We consider a Gaussian multiple access channel (GMAC) where the users are sensor nodes powered by energy harvesters. The energy harvester has no buffer to store the harvested energy and hence the energy need to be expended immediately. We assume that the decoder has perfect knowledge of the energy harvesting process. We characterize the capacity region of such a GMAC. We also provide the capaci...

Chemical Buffering Extracellular buffers, including plasma proteins, phosphates, and bicarbonate, are the earliest defense against acidosis. The most prominent extracellular buffer is bicarbonate, which is highly abundant and acts as a dynamic buffer by independently regulating Pco2 through changes in alveolar ventilation. This feature increases buffering capacity by more than 10-fold. Bufferin...

This paper examines the measures of performance and in particular addresses the throughput of an automated production line processing multiple products. The line is composed of a sequence of workstations connected in series with finite buffers in between. We explore the effects of buffer size on attenuating the impact of line blocking and starvation that can cause a reduction in the output. Suc...

This paper presents a new approach to global clock distribution in which traditional tree-driven grids are augmented with onchip inductors to resonate the clock capacitance at the fundamental frequency of the clock node. Rather than being dissipated as heat, the energy of the fundamental resonates between electric and magnetic forms. The clock drivers must only provide the energy necessary to o...

Nodes in Mobile Opportunistic Network (MON) have to cache packets to deal with the intermittent connection. The buffer management strategy obviously impacts the performance of MON, and it attracts more attention recently. Due to the limited storage capacity of nodes, traditional buffer management strategies just drop messages based on the property of message, and they neglect the collaboration ...

Objective: The study proposes using the dolomite buffer capacity (BCDolomite) as a method of estimating lime requirement in soils that agronomically require pH increase. Design/methodology/approach: In six soil samples with different levels response to application dolomite, organic matter (OM), content sand, silt and clay, pH, K, Ca, Mg potential acidity (Al+H) were determined. Assuming an appa...
