the objective of this study was to evaluate the effects of weaning age on dry matter intake (dmi), average daily gain (adg), feed efficiency (fe), feed cost (fc) and benefit index (bi) of holstein calves reared under organic farming system. thirty two holstein calves were divided into two treatments: early weaning (ew) vs. late weaning (lw). calves in the both groups were provided with whole mi...

Centralized procurement is now the development trend of procurement management of large enterprise groups at home and abroad. State Grid Materials Co, Ltd has accumulated rich experience of providing agent services to many international tendering projects including those using the World Bank and the Asian Development Bank loans. It has developed a standardized centralized procurement procedure ...

This paper studied pricing, service level, and production quantity decision problems in a supply chain with one manufacturer and one retailer under demand and production cost disruptions. The joint impact of demand and production cost disruptions on optimal pricing, service level, and production decisions in centralized and decentralized supply chain was analyzed, respectively. By solving the o...

Electric vehicles (EVs) are becoming increasingly popular in ride-hailing services, but their slow charging speed negatively affects service efficiency. To address this challenge, we propose PROLIFIC, a deep reinforcement learning-based approach for efficient EV scheduling and services. The objective of PROLIFIC is to minimize passenger waiting time cost. formulates the problem as Markov decisi...

the aim to achieve in this study is to recover the cr(iii) and process waters used in thewastewaters of chrome tanning operation by membrane process during leather production. in the treatmentalternative contains, cartridge filter, nanofiltration (nf(np10)), nanofiltration nf(xn45) and reverse osmosisro(acm2) membranes. the raw chrome wastewater from the cartridge filter was given to nf(np10)me...

A face recognition system gains flexibility and cost efficiency while being integrated into a wireless network. Meanwhile, face recognition enhances the functionality and security of the wireless network. This paper proposes a distributed wireless network prototype, consisting of feature net and database net, to accomplish face identification task by optimally allocating network resources. The ...

Topology control is one of the main techniques that can be used to decrease energy expenditure and/or interference in wireless sensor networks. Less attention, however, has been devoted to algorithms that address energy and interference efficiency together. In this paper, we describe a localized topology control algorithm called TCO which is very efficient in terms of interference while minimiz...

The evolvable multiprocessor (EvoMP), as a novel multiprocessor system-on-chip (MPSoC) machine with evolvable task decomposition and scheduling, claims a major feature of low-cost and efficient fault tolerance. Non-centralized control and adaptive distribution of the program among the available processors are two major capabilities of this platform, which remarkably help to achieve an efficient...

Abstract – This paper is concerned with the performance of distributed and centralized fusion with best linear unbiased estimation (BLUE), also known as linear minimum mean-square error (LMMSE) estimation, and optimal weighted least squares (WLS) estimation. Necessary and sufficient conditions for optimal distributed fusion rules to have identical performance as their centralized counterparts a...

The coordination problem of relief items’ distribution operations is essential in humanitarian relief chains. If the coordination is proper, it will improve the response phase to the crisis. In order to improve the coordination in humanitarian relief chains, distribution and warehousing operations of relief items were outsourced to the third-party logistics. In this paper, the procurement-distr...
