First, this paper derives the prefix sum-of-products expression (PreSOP) and the number of products in a PreSOP for an interval function. Second, it derives Ψ(n, τp), the number of n-variable interval functions that can be represented with τp products. Finally, it shows that more than 99.9% of the n-variable interval functions can be represented with 2n − 1 products, when n is sufficiently larg...

Network configuration and policy updates occur frequently, and must be performed in a way that minimizes transient effects caused by intermediate states of the network. It has been shown that accurate time can be used for coordinating network-wide updates, thereby reducing temporary inconsistencies. However, this approach presents a great challenge; even if network devices have perfectly synchr...

The electrochemical detection of NADH is of considerable interest because it is required as a cofactor in a large number of dehydrogenase-based biosensors. However, the presence of oxygenated functionalities on the electrode often causes fouling due to the adsorption of the oxidised form, NAD(+). Here we report an electroanalytical NADH sensor based on DMF-exfoliated graphene. The latter is sho...

Ternary Content Addressable Memory (TCAM) is a hardware device which can support high-speed table lookups and is an attractive solution for applications such as packet forwarding and classification. We investigate various TCAM architectures recently proposed for TCAM power and memory reduction in packet forwarding and show that far better power and memory performance is possible when we use an ...

This study was carried out in order to evaluate the changes of Nitrogen, phosphor and potassium uptake by wheat and remaining of them in soil under foliar application of Leonardite and foliar application of N and K. The experiment was conducted in Gorgan University of Agricultural Sciences and Natural Resources during 2013- 2014. The experiment was laid out a using split-plot arrangement based ...

bituminous emulsion insulators are types of bituminous emulsions groups composed of different grades of bitumen emulsified in water by bentonite and emulsifiers at 80-90oc. these emulsions are water resistant after drying andtheir physical and mechanical properties are superior in comparison to bitumen properties. iranian climate, because of variety and extreme variations in temperature imposes...
