摘要：双惯量谐振系统易产生低频机械谐振现象,针对此问题设计了带有前馈+反馈控制的双自由度速度控制器和全状态反馈控制器。结合电机和负载的动力学方程建立双惯量谐振系统数学模型,基于此模型设计双自由度及状态反馈控制器,考虑控制系统的参考输入跟踪能力以及抗扰动力矩能力,采用不同的极点配置策略对控制系统的增益进行求取。对比仿真试验结果验证了本文该速度控制算法的可行性和有效性。

摘要：电子仓单是供应链物流流转过程中的重要凭证,电子仓单及其背后的仓储过程信息必须是可信且不可修改的,而传统数据库技术无法有效解决这一问题.针对仓储物流中物联网的特点,利用区块链技术设计了区块链系统以存储电子仓单及相关物联网信息的总体框架,并设计了基于信誉度的共识算法.基于Bitcoin源码设计了可以存储各种信息以及适合交易运算的底层区块存储系统,并且设计了可以交易电子仓单以及存储仓储信息的交易算法.实验证明了该系统的有效性和可行性.

摘要：Sluggish kinetics of anodic hydrogen oxidation reaction(HOR)in alkaline media,which arises from the two orders of magnitude lower HOR activity in alkali than that in acid media for platinum group metals,hinders the commercial implementation of anion exchange membrane fuel cells(AEMFCs).Consequently,the development of platinum-based catalysts combined with high efficiency and durability is urgently ***,we report a facile route for the synthesis of ternary PtRuTe alloy nanofibers with Pt atomic ratio of only 11%via a simple galvanic replacement *** optimize the adsorption strength of platinum and ruthenium towards hydrogen and hydroxyl species by regulating the electron donation from tellurium to platinum and ***,the obtained trimetallic alloy catalyst exhibits an impressive kinetic current density of 30.6 mA cm^(−2)_(geo) at 50 mV and an exchange current density of 0.426 mA cm^(−2)_(metal),which shows 3.0-and 2.5-fold enhancement compared with the commercial Pt/C in alkaline electrolyte,***,the catalyst also demonstrates excellent stability with merely 5%activity attenuation after 2000 potential *** work offers new pathways to boost alkaline HOR by rationally designing multicomponent alloys.

摘要：贵州花灯剧是贵州成形最早,传播最广的地方戏曲剧种,已列入国家级非物质文化遗产名录。贵州花灯是广大城乡群众喜闻乐见的"草根"艺术,具有浓郁的乡土气息和独特的艺术风格,而今这一"非遗"濒临消亡、失传,亟待抢救和保护传承。

摘要：随着计算机技术的不断发展,展示手段日益多样化。虚拟现实等高新技术融入到展示设计中,互动性、综合性和现场感得到加强。展示设计是一项包含多种学科的综合性艺术设计,主体是商品与文化,涵盖领域非常广泛,更符合信息时代人们的多种感官要求。基于此,分析虚拟现实技术在各大展示展览中的具体应用,阐述其设计原理和应用技术,指出其不同的应用价值和意义。

摘要：为提高常规公交的出行服务质量,建立了考虑车内拥挤状态的公交弹性发车间隔优化模型.通过量化车内拥挤状态,给出各拥挤状态下的乘车成本;建立了线路各区间的拥挤状态转移函数.考虑乘客的车内拥挤状态感知,建立站点乘客随时间的上下车数量的度量模型;构建乘客出行成本度量模型,以乘客出行成本与车辆运营亏损之和最小化为目标函数,建立了公交弹性发车间隔优化模型;并设计遗传算法对模型进行求解.结果表明:优化模型能够有效降低出行成本.模型对等待成本有着“补短板”效果,对乘车成本有着“削峰”效果,即通过增加乘客到站量小站点的等待成本,降低乘客到站量大站点的等待成本,削弱乘车成本峰值的手段,达到总成本最低的效果.

摘要：针对数字文化产业人才结构性短缺问题,通过调研无锡市10所高职院校相关专业的专业建设和人才培养情况,提出了“群链对接、产学联动”的数字媒体专业群建设思路,并以无锡商业职业技术学院为例分析了数字媒体专业群的组群逻辑,探索构建出“一二三四五”产教协同育人体系。

摘要：部分病人对其电子病历访问有全程管控的特殊需求,而现有云环境下的电子病历共享系统却无法满足这一需求,于是提出了一种基于超级账本和星际文件系统的电子病历安全访问方案HyperEHR.该方案设计了由病历请求者所在机构以及病人双重审核且由病人决定病历最终访问权的方法.为保证跨机构之间的医疗数据安全互访,将病历生成、更新以及访问等信息存储在联盟链区块中,而将各医院、诊所产生的具体病历信息和访问控制策略加密存储在云端星际文件系统中.系统实现及分析表明:该方案有较好的可扩展性、互操作性及安全性,可满足病人对其医疗数据访问的管控,有效防止病历隐私泄露.
