Using Blockchain Technology in Mobile Network to create decentralized Home Location Registry (HLR)

Blockchain can mean many things to many people. It is a set of protocols and encryption technologies for securely storing data on a distributed network for the developers. It is a distributed ledger for business and finance and the technology underlying the explosion of new digital currencies. For technologists, it is the driving force behind the next generation of the internet. On the other hand, it is a transformational technology facilitating large-scale human progress in previously unimagined ways for the rest of the people, a tool for radically reshaping society and economy. Some view it as a disruptive technology that can be the source of a great deal of fraud, illegal activity, where others see opportunities to bring into existing systems by providing decentralization, transparency, and efficiency. This complex technological, economic, and social phenomenon has been the subject of fervent debate. It calls into question what might have been seen to be established parameters of the modern world like currency, economics, trust, value, and exchange. It is a revolutionary new computing paradigm and one of the most significant, fundamental digital platforms’ advances since the internet. It is an emergent technology experiencing very rapid evolution, and so is our understanding of what it is and what it can be. This paper is subject to the use of Blockchain concepts in mobile networks to strengthen the Home Location Registry (HLR) database and make it decentralized for secure transactions and in banking and financial centers. Blockchain also holds potential implications for global commerce. It could make trade more efficient by removing the manual and paper-based processes and introducing streamlined and automated processes.     

基于STC单片机的家庭安全防护报警系统设计

为优化传统安防系统设计,实现家庭安全防护的智能化、自动化以及使用上的便捷化,本文基于STC89C52单片机的家庭安全防护报警系统是由单片机、液晶键盘模块、GSM模块、实时时钟模块和传感器模块组成。它借助GSM移动网络,以最直观的短消息形式,直接把报警情况通过手机发送给用户。主要结论表明,本设计较好地解决了传统机械式防有毒气体泄漏、防盗等弊端;能减少和避免户主的损失;提高系统的可移动性。     

Socially Inclusive Design in Denmark: The Maturing Landscape

With a tradition of social inclusion and innovative contemporary design, Denmark leads the way internationally in its architectural provision for an older population. Architect, author and researcher Terri Peters highlights some pioneering housing schemes in Denmark that use architecture to reduce the stigma of old age in the creation of environments that are overtly ‘homey’ or domestic – breaking away from the sanitised environment of the ‘nursing home’ – and that employ nature and landscape to positive effect, as a means of promoting healing and health.     

家电下乡售后服务存在的问题及对策

家电下乡作为一项全新的支农惠农政策,在有效促进家电生产、流通和农民需求三者有机对接的同时,随着政策的不断深入,也曾暴露出一些缺陷和弊端,出现了短期销售业绩显著、长期增长乏力等问题。基于我国目前家电下乡政策实施现状,本文就其售后服务环节上所存在的不足进行了初步归纳并提出了相关解决方案。     

一种分层移动IPv6路由优化模型的分析与研究

分层MobileIPv6架构中的HomeAgent在处理MobileNode移动而产生的信息传输问题时,有可能因Mobile Nodes与Correspond Nodes的节点过多而疲于应付信息的传送,这给Home Agent带来巨大负担而影响到Mobile IPv6的整体运作性能.为此,提出一种高性能路由优化模型,以提高Home Agent在Mobile IPv6中对MN位置移动的反应能力,同时改进移动后MN传输信息的性能.     

农民工返乡创业行为决定因素调查研究——以江西省为例

近两年,由于受金融危机影响而导致的就业压力变大,以及国家政策推动等方面因素的影响,返乡创业的农民工数量有了明显的增多,但其行为决定因素却是多样。本文通过实地调查,对农民工返乡创业行为的诸多决定因素进行深入分析研究,并提出相应的对策。     

家用洗涤过程对氨纶纬编针织物弹性性能的影响

采用不同洗涤条件对3种常见的氨纶纬编弹性针织物进行洗涤,比较织物弹性性能的变化。实验表明,家用洗涤对棉织物的弹性有较大影响,对化纤织物弹性影响较小。40℃洗涤温度是氨纶弹性织物比较合适的洗涤温度。自来水中的有效氯浓度对织物的弹性没有显著影响。不同品牌的洗衣粉对织物弹性的影响有所不同,活性氧有加大织物弹性损伤的趋势。     

无线家庭网络的网关设计

针对无线家庭网络中的核心设备-网关，设计了以ARM Core 32位高性能处理器及嵌入式操作系统μCOSⅡ为核心，以Bluetooth技术构建家庭内部网络，即个人局域网PAN(personal area network)；以2.5G移动通信网络GPRS技术组成信息外部传输网络，具有从而设计了可移动、功能强大、低成本、技术先进的无线家庭网关．     

试论国有企业摆脱困境走向市场的对策

市场经济的发展,要有一个与之相适应的充满生机和活力并积极参与市场竞争的企业主体作为其微观基础。而我国的国有企业由于正处在从计划经济体制向市场经济体制的转变过程中,当前的处境仍十分艰难。国有企业如何摆脱困境,走向市场,这是一个需要花大力气进行研究的重要社会课题。本文从确立自主企业制度、明晰产权关系、选聘管理人员、减轻国有企业社会负担等多个方面进行了全面系统的对策研究。
