In this paper, we present an eecient algorithm to compute a tighter lower bound for the one-dimensional bin packing problem. The time complexity of the algorithm is O(n log n). We have simulated the algorithm on randomly generated bin packing problems with item sizes drawn uniformly from (a; b], 0 a < b B. If our lower bound is used, on average, the error of BFD is less than 2%. For a + b B, th...

Abstract The Yellow River (YR) is famous for its ‘hanging river’ due to the high sedimentation rate in lower reaches. Reservoir sediment retention (RSR) and water–sediment regulation (WSR) of Xiaolangdi (XLDR) contribute mitigating siltation adjusting bankfull channel geometry (LYR). However, few studies have been conducted quantify contribution RSR WSR medium-sized shaping. In this paper, we a...

Abstract In this paper, we design full-duplex (FD) medium access control (MAC) protocol for co-existing wireless local area networks (WLANs) in 5G cellular (WCFD-MAC). Our considers some significant features of networks, exceptionally, beamforming and FD capabilities at both, the base station user equipment. communications may generate interferences, namely self-interference (SI) bidirectional ...

Given data d ∈ R , we consider its representation u involving the least number of non-zero elements (denoted by l0(u∗)) using a dictionary A (represented by a matrix) under the constraint ‖Au− d‖ ≤ τ , for τ > 0 and a norm ‖.‖. This (nonconvex) optimization problem leads to the sparsest approximation of d. We assume that data d are uniformly distributed in θBfd (1) where θ>0 and Bfd (1) is the ...

Ingested inorganic arsenic is strongly associated with a wide spectrum of adverse health outcomes. We propose a bioaccumulation and the Weibull model-based epidemiological framework to accurately estimate the reference arsenic intake guideline for tilapia consumption and tilapia-cultured water arsenic concentration based on bioaccumulations of tilapia and gender/age/cancer-specific epidemiologi...

Segmental dorsolumbar epidural anesthesia has been considered difficult to perform. The purpose of this study was to determine whether or not it is difficult for beginners to learn how to do modified dorsolumbar epidural anesthesia of cattle. Thirty cattle were divided into two groups, young (n = 8) and adult (n = 22), according to their age and body weight, and 0.12% new methylene blue (NMB) w...

The CMC, BFD, and CIE94 color-difference formulas have been compared throughout their weighting functions to the CIELAB components DL*, DC*, DH*, and from their performance with respect to several wide datasets from old and recent literature. Predicting the magnitude of perceived color differences, a statistically significant improvement upon CIELAB should be recognized for these three formulas...

Quantitative analysis for the risk of human cancer from the ingestion of inorganic arsenic has been based on the reported cancer mortality experience in the blackfoot disease (BFD) -endemic area of southwest Taiwan. Linear regression analysis shows that arsenic as the sole etiologic factor accounts for only 21% of the variance in the village standardized mortality ratios for bladder and lung ca...

Parameter (or variable) of automotive embedded networked control system is named as signal. In order to improve system performance and provide more remaining bandwidth for system extension, it is necessary to minimize the bandwidth consumption of frames transmitting the datum of signals. In this paper, the signal framing problem and methods of automotive embedded networked control system for ba...
