This paper proposes an improved Deeplabv3+ model for semantic segmentation of urban scenes targeting autonomous driving applications. A high-quality dataset is constructed from 2,967 manually labeled aerial images captured at 200m height with a 5-eye camera. The contain 5 classes - buildings, vegetation, ground, lake and playgrounds. network enriches high-level semantics by replacing max pooling depthwise separable convolutions. Dilated convolutions extract multi-scale features to avoid...

From the perspective of Micro-Low-Carbon Economy, this paper studies low-carbon manufacturing decision model enterprises considering carbon emission trading and green technology input under cap.The shows that have optimal output is unique addressed three situations: trading, joint decision.The research brings more flexibility to enables increase their profits, however, maximum expected profit in (higher than, equal to, or lower than without cap constraint) mainly depends on initially granted...

Abstract This paper studies the optimal low carbon production decision system with considered constraints of emission reduction policy for manufacturing enterprises producing two kinds products in free market. Firstly, The research proved combination exists and it is unique under emissions limits, next, analyzed low-carbon decision-making three situations, which are trade decision, green technology input joint decision. results showed that permits can increase more flexibility to their...

This paper aimed to explore the difference in spatial distribution of compulsory education resource allocation. Raw data were collected from 2020 China Statistical Yearbook (county/district level) and Guangxi Province China. Data analysis was conducted using entropy method, comprehensive evaluation K-means clusters analysis, variance, statistical (Moran’s I index). It determined that there significant differences education. The equilibrium degree mandatory allocation divided into three...

In recent years, artificial intelligence (AI) technology garnered widespread attention and applied to various aspects of human life.Supported by Internet technology, AI transformed traditional problem-solving methods utilizing information as a medium for sharing communicating.It has significantly streamlined processing, playing crucial role in promoting the economic development society driving technological progress.This study aimed investigate relationship between self-efficacy, learning...

Abstract This paper researches the pricing strategy and government intervention mechanism for green supply chain in monopoly market, while considering strategic customer behavior. According to optimization theory, it establishes target functions of retailer customers investigates interactions between accordance with Stackelberg’s game so as confirm optimal discount level products. In addition, discusses regulatory effect intervention, including guiding price fiscal subsides, on sales The...

With the increasing competition of retail trade in China, only meeting customer's demand exactly and quickly developing service level revenue maximization, do enterprise can beat competition. The inventory management is key to success. It vital place operation management, because it relates cost has an influence on economic benefits level. traditional use strategy based natural property commodity. But ignores difference different goods contribution. This paper mostly according thought uses...

In recent years, increasing temperatures and extreme weather conditions have had a significant impact on quality of life, especially in terms the environment.Governments made environmental preservation priority received public support turn.We formulate models to investigate company's optimal production quantities over two periods, including green technology efforts, examine carbon trading policy.We build separate inter-temporal under cap policies based news vendor theory.Then, we utilize...

This paper researches the two products production strategy under cap and trade policies by newsboy model. The green product could be regarded as an equivalent of regular product. useful conclusions can obtained: 1) establishment will benefit for improvement manufacture performance. 2) After technology input, quantity raise decrease. 3) There is expectant profit that earned through selling extra carbon emission or buy less from outside market after input policy.

This paper deals with a production model involving one manufacturer who produces two products. One product adopts green technology and we term the as 'green' product, other regular technique, termed 'regular' product. In this paper, formulate models to examine impact of for products under cap-and-trade policy. Analytical results are obtained: policy, manufacture's maximum quantity 1 2 is lower than case without carbon emission constraint, expected profit situation depends on initial...

In this paper, an improved differential evolution algorithm is proposed to improve the positioning accuracy of electronic wristband system.The system composed STM32F103 microcontroller, Beidou module, LORA communication module and so on.In traditional algorithm, premature convergence local optimal will reduce algorithm.To solve problem, method introduces distance information between known unknown points all in fitness function overall initialization.This reduces improves optimization ability...

It takes a long time to detect target information in noisy radar and reduce the probability of false alarm.Therefore, it has become research direction alarm effective detection.This paper introduces new method occurrence non-uniform environment improve efficiency detection.The proposed involves faster more stable that preprocessing data set, splitting into smaller parts, utilizing KTH minimum value M determined by an ordered statistics class constant detection algorithm.Each point small...

Based on the stochastic market demand of products, this paper studies low-carbon manufacturing decisions making enterprises considering downward substitution and green technology input under carbon cap-and-trade policy. The results show that government’s trade policy will have a great impact production enterprises. Therefore, must attach importance to constraints emission reduction policies. In terms it, there are strategies for such as adjusting output, trading right, so on. On case, can...

Considering the fuzzy and uncertainty of evaluation information object, type indicators are expanded into five types mixed information, namely, exact number, interval triangular hesitant probabilistic linguistic term sets, different adopted according to characteristics indicators, respectively. When is hybrid generalized Shapley function based on measurement used analyze interaction between determine weights considering that more complicated. In view fact conversion same kind will lead...

With the carbon trading policy, it's important for enterprises to use a production and pricing strategy. This paper aims make study of joint strategy manufacturing by establishing cost functions newsboy model. Enterprises will sell out their remaining quotas if emission is less than its quota. shows that quota adversely impact profit enterprises. At same time, under cap-and trade differences between an enterprise's are compared, then compared purchasing per unit marginal producing products....

In this paper, we study the monopoly market two products manufacturing enterprises in carbon cap and trade policy, respectively, for emissions trading decisions, green technology investment decision, portfolio decision three cases optimal pricing decision. The combination of product under conditions is presented. research results show that government's quota will have an important impact on policy enterprises, can optimize improve decisions to a certain extent.

This paper researches a green supply chain comprised of one manufacturer and retailer. We build the profit model whole considering strategic customer behavior, compare two kinds optimal order quantity this under traditional mechanism option mechanism. Research shows that fails to maximize chain, while can increase equal which maximizes so as coordinate chain.

With the rapid development of e-commerce and adoption dual channels, conflict governance for channel is focused problem. In this paper, we use a game theory approach to investigate issue; explore manufacturer retailer integrate delivery coordinate realize win-win. We examine how market share relative intensity price competition impact cooperation implement mechanisms.
