The Low Pass Filter (LPF) model used to calculate the average queue length in the original RED results in a poor time response, low throughput, and high delay. We proposed a new algorithm, called Low Pass Filter/Over Drop Avoidance (LPF/ODA), to improve the performance of RED gateways. Simulation results have shown that our LPF/ODA algorithm significantly improves the time response of RED gatew...

We give two optimal linear-time algorithms for computing the Longest Previous Factor (LPF) array corresponding to a string w. For any position i in w, LPF[i] gives the length of the longest factor of w starting at position i that occurs previously in w. Several properties and applications of LPF are investigated. They include computing the Lempel-Ziv factorization of a string and detecting all ...

The Longest Previous Factor (LPF) table of a string s of length n is a table of size n whose i element indicates the length of the longest substring of s starting from position i that has appeared previously in s. LPF tables facilitate the computing of the Lempel-Ziv factorization of strings [20, 21] which plays an important role in text compression. An open question from Clément, Crochemore an...

AI software is often used as a means for providing greater autonomy to automated systems, capable of coping with harsh and unpredictable environments. Due in part to the enormous space of possible situations that they aim to addrs, autonomous systems pose a serious challenge to traditional test-based verification approaches. Efficient verification approaches need to be perfected before these sy...

A novel compact microstrip lowpass filter (LPF) is proposed in this paper, which consists of the complementary rectangle split ring defected microstrip structure (CRSR-DMS), open stubs, spurline and the dumbbell-shaped defected ground structure (DGS). Due to the unique response of the presented CRSR-DMS, a low passband insertion loss and a sharp transition of the proposed LPF was achieved. Mean...

Partial functions and operators are used extensively in the formal development of programs and thus development methods have to clarify how to reason about them. There are a number of approaches which cover up the fact that “First Order Predicate Calculus” does not handle undefined logical values. There is also at least one specific “Logic of Partial Functions” (LPF) which tackles the issue at ...

OBJECTIVE The use of locally produced forage (LPF) in cattle production has economic and environmental advantages over imported forage. The objective of this study was to characterize the nutritional value of LPF commonly used in Korea. Differences in ruminal fermentation characteristics were also examined for the LPF species commonly produced from two major production regions: Chungcheong and ...

In the study, we propose a method to select components from datasets to form two kinds of categorizes {reqProcessing, noProcessing} for tempogram selector, which is built from a classifier. The research utilizes the low pass filtering (LPF) as the processing, so there are two tempogram with LPF or without LPF. The trained classifier is used to select the best out of the tempograms, which repres...

Abstract This paper describes new proposed algorithms for constructing the transfer function of nth order Butterworth LPF using the idea of the cascade combination of active filters. Computer-aided design is used with new algorithms to achieve the procedure of constructing the transfer function and give the practical results of the nth order Butterworth active LPF. C++ program is used for desig...

─ A novel quarter-circle defected ground structure shape is introduced in this paper to design and implement an ultra-wide reject band low-pass filter (LPF). Moreover, an equivalent circuit model (ECM) is presented. The proposed LPF has small size and, a low insertion loss and a return loss less than -20 dB. Also, a round -20 dB suppression level ranging from 4 GHz to more than 20 GHz is achiev...
