外空活动私有化和商业化的趋势凸显了外空知识产权保护的重要性,外空知识产权保护法律制度的重构必须考虑外空法基本原则的要求。外空智力成果并不因其完成地点为无主权的外空而受到影响,各国可以根据本国知识产权法决定是否授予知识产权。但在确定外空智力成果知识产权客体范围及对外空知识产权进行限制时,应对现行知识产权法进行改造,以兼顾外空法基本原则的要求和鼓励外空科技创新的目的。类推船旗国法理论将登记国法适用于在该国登记的外空物体存在理论和实践的缺陷,在国内法和国际条约中直接予以规定不失为一种较好的协调方式,而"外空本身"的知识产权保护问题,则仍需通过国际条约予以解决。

以拟薄水铝石焙烧得到的γ-Al2O3为载体,分步浸渍负载(NH4)2S2O8、ZrOCl2和Cu(NO3)2,制成Cu/ZrO2/S2O28-/γ-Al2O3固体酸催化剂.考察了Cu/ZrO2/S2O82-/γ-Al2O3在富氧条件下对C3H6选择还原NO的催化性能,并借助SEM、XRD、Py-IR和TPR等表征方法研究了它的结构和性能的关系.性能的实验结果表明,Cu/ZrO2/S2O28-/γ-Al2O3在无水条件下能使NO的最大转化率达到82.9%,在有10%水蒸气存在条件下仍能使NO的最大转化率达到80.2%.表征测试的结果表明,S2O82-和ZrO2能够抑制γ-Al2O3颗粒之间的烧结及CuAl2O4尖晶石相的生成,同时促使催化剂表面新酸性中心(B酸)的形成及总酸量的增加,另外ZrO2还能提高Cu物种的还原性,从而有效地改善了催化剂的催化活性和水热稳定性.

With the emergence of industry 4.0 and Internet of things(IOT), more and more practical requirements need seamless connection from the smallest sensor to enterprise level systems and other systems with simple, convenient, reliable and economic approach. LoRa is a low-power wide area network(LPWAN) solution specifically designed for IoT devices that send and receive small amounts of data over a range of many kilometers with minimal power consumption. At the system architecture level, Lora is considered as a physical layer technology based on OSI model, mainly based on Chirp spread-spectrum(CSS) technology. LoRa is resulted in a robust and reliable technology compared to other standardized wireless solutions such as Zigbee, Bluetooth, WiFi, and 3 G/4 G cellular. In this paper, we have designed a single-channel LoRa gateway for Industrial IoT cloud applications using inexpensive single-board computer naming Raspberry Pi plus a LoRa add-on board with the necessary integrated circuits for wireless data communication. The system adopting the LoRa LPWAN technology consists of end devices, gateways, and cloud IoT services. The proposal gateway sends and receives LoRa messages to and from end devices and communicates with upstream cloud application servers through HTTP RESTful protocol and IoT-standard MQTT protocol, according to different data types and specific functional requirements. Unlike other ready-to-use LoRa gateways available on the market in which these gateways simply pass all the original LoRa packets back and forth between and network server over the air called "packet forwarding" mode, the proposal gateway contains smart-agent managing connectivity to devices, coordinating polling mechanism, decoding the packets, passing periodically the unified data to the public or private cloud service applications. Aside based on the embedded web server, the configuration of the gateway is carried out through the web page with desktop or mobile application and it can be u

采用泛化和抑制技术对数据进行K匿名化处理,需要在数据的有用性和隐私保护度之间保持平衡。提出一种新的利用基于差异信息理论的灰关联分析实现K匿名的方法,利用数据序列之间的均衡接近度描述数据点之间的相似程度,据此进行相应的泛化和抑制操作,并将K匿名后的数据应用于聚类分析。在真实数据集上的测试验证了该方法的有效性。
