Rapid development in Information Technology(IT)has allowed several novel application regions like large outdoor vehicular networks for Vehicle-to-Vehicle(V2V)transmission.Vehicular networks give a safe and more effective driving experience by presenting time-sensitive and location-aware data.The communication occurs directly between V2V and Base Station(BS)units such as the Road Side Unit(RSU),named as a Vehicle to Infrastructure(V2I).However,the frequent topology alterations in VANETs generate several problems with data transmission as the vehicle velocity differs with time.Therefore,the scheme of an effectual routing protocol for reliable and stable communications is significant.Current research demonstrates that clustering is an intelligent method for effectual routing in a mobile environment.Therefore,this article presents a Falcon Optimization Algorithm-based Energy Efficient Communication Protocol for Cluster-based Routing(FOA-EECPCR)technique in VANETS.The FOA-EECPCR technique intends to group the vehicles and determine the shortest route in the VANET.To accomplish this,the FOA-EECPCR technique initially clusters the vehicles using FOA with fitness functions comprising energy,distance,and trust level.For the routing process,the Sparrow Search Algorithm(SSA)is derived with a fitness function that encompasses two variables,namely,energy and distance.A series of experiments have been conducted to exhibit the enhanced performance of the FOA-EECPCR method.The experimental outcomes demonstrate the enhanced performance of the FOA-EECPCR approach over other current methods. 展开更多

Since 2016,the National Institute of Standards and Technology(NIST)has been performing a competition to standardize post-quantum cryptography(PQC).Although Falcon has been selected in the competition as one of the standard PQC algorithms because of its advantages in short key and signature sizes,its performance overhead is larger than that of other lattice-based cryptosystems.This study presents multiple methodologies to accelerate the performance of Falcon using graphics processing units(GPUs)for server-side use.Direct GPU porting significantly degrades performance because the Falcon reference codes require recursive functions in its sampling process.Thus,an iterative sampling approach for efficient parallel processing is presented.In this study,the Falcon software applied a fine-grained execution model and reported the optimal number of threads in a thread block.Moreover,the polynomial multiplication performance was optimized by parallelizing the number-theoretic transform(NTT)-based polynomial multiplication and the fast Fourier transform(FFT)-based multiplication.Furthermore,dummy-based parallel execution methods have been introduced to handle the thread divergence effects.The presented Falcon software on RTX 3090 NVIDA GPU based on the proposed methods with Falcon-512 and Falcon-1024 parameters outperform at 35.14,28.84,and 34.64 times and 33.31,27.45,and 34.40 times,respectively,better than the central processing unit(CPU)reference implementation using Advanced Vector Extensions 2(AVX2)instructions on a Ryzen 95900X running at 3.7 GHz in key generation,signing,and verification,respectively.Therefore,the proposed Falcon software can be used in servers managing multiple concurrent clients for efficient certificate verification and be used as an outsourced key generation and signature generation server for Signature as a Service(SaS). 展开更多

Reliable sales forecasts are important to the garment industry. In recent years, the global climate is warming, the weather changes frequently, and clothing sales are affected by weather fluctuations. The purpose of this study is to investigate whether weather data can improve the accuracy of product sales and to establish a corresponding clothing sales forecasting model. This model uses the basic attributes of clothing product data, historical sales data, and weather data. It is based on a random forest, XGB, and GBDT adopting a stacking strategy. We found that weather information is not useful for basic clothing sales forecasts, but it did improve the accuracy of seasonal clothing sales forecasts. The MSE of the dresses, down jackets, and shirts are reduced by 86.03%, 80.14%, and 41.49% on average. In addition, we found that the stacking strategy model outperformed the voting strategy model, with an average MSE reduction of 49.28%. Clothing managers can use this model to forecast their sales when they make sales plans based on weather information. 展开更多

Due to the lack of long-range association and spatial location information,fine details and accurate boundaries of complex clothing images cannot always be obtained by using the existing deep learning-based methods.This paper presents a convolutional structure with multi-scale fusion to optimize the step of clothing feature extraction and a self-attention module to capture long-range association information.The structure enables the self-attention mechanism to directly participate in the process of information exchange through the down-scaling projection operation of the multi-scale framework.In addition,the improved self-attention module introduces the extraction of 2-dimensional relative position information to make up for its lack of ability to extract spatial position features from clothing images.The experimental results based on the colorful fashion parsing dataset(CFPD)show that the proposed network structure achieves 53.68%mean intersection over union(mIoU)and has better performance on the clothing parsing task. 展开更多

Falcon选矿机是一种新型的离心分选机.为研究其分选机理,以Falcon SB离心分选机为例,建立了球形颗粒在离心分选机分层区和分选区的动力学方程.分析结果表明,在Falcon SB分层区,高强度离心加速度是实现微细颗粒快速沉降的关键因素;分选区内独特的流态化反冲水形成流态化床层,使得微细高密度颗粒穿过床层沉积到来复圈槽中,而低密度颗粒所受的离心力较小,加上难以克服反冲水的作用而进入尾矿,从而实现了不同密度微细颗粒的有效分选.采用Falcon SB40选矿机分选-0.074 mm电路板的试验结果表明:在入料浓度为40 g/L,给料速度为160 L/h,反冲水压力为0.01 MPa,滚筒旋转频率为50 Hz时,一次分选获得金属富集体的品位为76.89%,回收率82.19%,综合效率80.77%. 展开更多
