Human, Nature, Harmony Self-service Travelling in Stockholm

I decided to visit my friends in Stockholm, Sweden in October. Took an overnight flight to Northern Europe from East Africa, and same as the return journey. It saved me two days of accommodation in this way. I can also go directly to the scenic spots if I am not tired after getting off the plane.

Customer-Value Creation in Self-service Technologies (SSTs) in the Tourism Industry

This paper explores and validates the process of customer value creation in self-service technologies(SSTs)in the context of the tourism industry.As the self-technology has been gradually advanced,its adoption in the tourism industry has brought many changes.A new trend of self-service technologies has helped service firms to save the labor costs and customers’waiting time for transactions.The purpose of this study is to confirm an applicability and a design of the original model of SSTs and explore the connection between SSTs and creation of value perception through a confirmatory factor analysis in the context of the tourism industry.Furthermore,the results of the online survey questionnaire from 234 responses in the United States and South Korea are explained in this study.The results of this study concluded that five statistically important factors are related to customers’motivations to use SSTs and enable customers to interact with SSTs as“SST location and capacity planning”,“SST service quality”,“motivations to use SST”,“SST design”,and“SST encounter”.These factors may imply an important meaning to better understand about customer value during the adoption of SSTs in the tourism industry.Tourism firms may use the results of this study to effectively enhance how customers perceive value about their products and services during the usage of SSTs.This will help tourism firms’efficiencies on the adoption of SSTs for their business plans and help them remain profitable in the competitive market.

The computer-aided design method of cabinet based on style imagery

Due to the practical problems of the high costs and the long development cycle of China’s cabinet production,a computer-aided design method of the cabinet based on style imagery is proposed.According to the principle of the conjoint analysis method, the rough set theory and the weight coefficient of different components of the cabinet,a multi-dimensional model of style imagery to evaluate the cabinet is built. Then the related constants of style imagery are calculated and the cabinet components library is also built by the three-dimensional modeling.Finally,with recombinant technology and the mapping model between cabinet style and external characteristics,the prototype system based on Visual Studio is proposed.This system actualizes the bidirectional reasoning between product style imagery and the shape features,which can assist designers to produce more creative designs,greatly improve the efficiency of cabinet development and increase the profits of companies.

Non-intrusive temperature rise fault-identification of distribution cabinet based on tensor block-matching

In this study,a novel non-intrusive temperature rise fault-identification method for a distribution cabinet based on tensor block-matching is proposed.Two-stage data repair is used to reconstruct the temperature-field information to support the demand for temperature rise fault-identification of non-intrusive distribution cabinets.In the coarse-repair stage,this method is based on the outside temperature information of the distribution cabinet,using tensor block-matching technology to search for an appropriate tensor block in the temperature-field tensor dictionary,filling the target space area from the outside to the inside,and realizing the reconstruction of the three-dimensional temperature field inside the distribution cabinet.In the fine-repair stage,tensor super-resolution technology is used to fill the temperature field obtained from coarse repair to realize the smoothing of the temperature-field information inside the distribution cabinet.Non-intrusive temperature rise fault-identification is realized by setting clustering rules and temperature thresholds to compare the location of the heat source with the location of the distribution cabinet components.The simulation results show that the temperature-field reconstruction error is reduced by 82.42%compared with the traditional technology,and the temperature rise fault-identification accuracy is greater than 86%,verifying the feasibility and effectiveness of the temperature-field reconstruction and temperature rise fault-identification.

Energy Conservation Effect of Refrigerated Cabinets at Supermarket Utilizing the Exhaust Heat from Dispersed Power

Since the nuclear disaster occurred from huge earthquake in Japan 2011, Japanese energy generation system has been expected to prioritize safety and trustworthiness. To meet this requirement, distributed power supply systems are considered to be one of solutions. In this study, we aimed to conserve energy and reduce carbon dioxide emission of supermarket which installed a novel environment-friendly dispersed power. We focused the energy used by refrigerated cabinets. We built small scale model of supermarket which was equipped with dispersed power. From this scale model, the energy conservation effect of supercooling is from 10% to 25% during the summertime and intermediate time. At last, we found that when outside temperature is about 14 ℃ or more, supercooling was effective. In addition, since energy consumption of refrigerated cabinet is influenced by inside enthalpy, we controlled the inside air temperature and humidity by installing desiccant system and examined its effect.

外卖配送电动自行车换电柜选址定容实证研究

针对外卖配送电动自行车换电柜布局不合理带来的部分换电柜利用率低与部分换电需求得不到及时满足的供需矛盾问题,本文通过聚类POI(Point of Interest)数据确定外卖配送起止点,并通过仿真模拟外卖骑手配送路径预测外卖配送电动自行车换电需求时空分布,构建换电柜运营商总成本最低和用户满意度最高的多目标换电柜选址定容模型,并以新乡市主城区为例,采用NSGA-II(Non-dominated Sorting Genetic Algorithm II)算法得到换电柜选址定容方案。研究结果表明:仿真模拟得出的换电需求时间分布预测值与实际值基本吻合,换电需求在11:00,14:00,17:00和20:00左右急剧增长,且11:00和14:00左右的换电需求量显著高于17:00和20:00左右的换电需求量,外卖骑手配送路径仿真模拟方法在换电需求预测上具有较高的预测精度;换电柜选址方案不能同时满足运营商和用户利益均为最优,用户满意度的提高需以增加运营商总成本为代价;同时,兼顾运营商和用户利益的新乡市主城区外卖配送电动自行车换电柜最佳建设数量为26,其中,容量为11的换电柜11个,容量为22的换电柜8个,容量为33的换电柜7个;新乡市主城区应按照备选点编号15-7-19-17依次新增换电柜至30个,此时,用户满意度最大,若继续增加换电柜建设数量,只会增加运营商总成本。

丧钟敲响:皇族内阁的社会反响与抗议风潮

1911年皇族内阁成立后,遭到各方反对。有的官员公开表达不满,本为阁员的官员的表态则暴露出清廷最高层的矛盾;各报刊给予持续的批评和讥讽;以各省咨议局联合会为中心的立宪派人士多次上书抗议,又联络各团体抗争,成为反对皇族内阁的核心,并引发持续的抗议风潮。立宪派人士反对皇族内阁的根本原因,在于他们完全不信任清廷权贵,不相信他们能领导国家走出危机。在国会请愿后出台的皇族内阁,使本已十分尖锐的清政府与立宪派及社会各方的矛盾更为激化,等于敲响了清王朝的丧钟。

分立式开关电源系统抗震性能的振动台试验研究

开关电源是通信机楼和通信基站中最重要的设备之一,相当于机楼和基站内供电系统的“心脏”,若在地震作用下发生功能失效将导致通信机楼和基站完全停止工作。开关电源的抗震性能研究是通信系统抗震韧性评估研究的基础。本文以通信机楼内常用的分立式开关电源系统为研究对象,通过振动台试验研究其在地震下的特征损伤模式、损伤发展过程以及其供电功能在地震作用下的变化等。试验过程中为了模拟开关电源在通信机楼中的实际使用状态,为开关电源连接了380 V电压输入和一台模拟负载,组成了一个完整的用电系统。试验中台面激励采用了1条人工地震动、1条天然地震动和1条正弦拍波,逐步增大台面PGA直至振动台位移超限停止试验。从试验结果看:当PGA达到1.0 g时电源柜开始损伤,表现为柜门与主框架磨损掉漆,PGA在1.2~1.5 g时,电源柜顶部连接松动,面板连接螺丝松动,螺栓孔发生冲切破坏,PGA达到2.0 g时,试验结束,电源柜的主体未发生严重破坏,交流柜与直流柜前门轴变形;另外即使在较大PGA下,正弦拍波也无法对电源柜激起较大位移而造成破坏。试验过程中电气信号始终稳定,该开关电源柜抗震性能良好。
