Blockchain in Additive Manufacturing and its Impact on Supply Chains

Additive manufacturing (AM) appears to be a particularly attractive use case for blockchain. This research combines inductive in‐depth interviews with the Delphi method to explore what potentials blockchain technology in AM creates, which adoption barriers firms need to overcome, and how supply chains will be affected by the integration of these two potentially disruptive technologies. The results suggest opportunities that are related to intellectual property (IP) rights management, the monitoring of printed parts throughout their lifecycle, process improvements, and data security. The most important barriers for blockchain adoption in AM are an absence of blockchain‐skilled specialists on the labor market, missing governance mechanisms, and a lack of firm‐internal technical expertise. By addressing important limitations of AM, blockchain is expected to improve the competitiveness of AM in parts’ production, catalyzing the trend toward more decentralized manufacturing resulting in more agile, resilient, and flexible supply chains and reduced logistics costs. Beyond that, blockchain‐based AM platforms are expected to enhance supply chain visibility, drive supply chain digitalization, support supply chain finance, and contribute to the emergence of shared factory systems.

Reconfiguring the innovation policy portfolios for Taiwan's SIP Mall industry

Since the year 2000, silicon intellectual property (SIP), which can minimize the gap in ‘design productivity’ that exists with systems-on-chip (SOC), has become one of the most important factors in the development of integrated circuit (IC) products in the SOC era. Although SIP is very important for IC industry development, complicated business, technical as well as legal issues inside SIP transactions have hindered successful transactions and the integration of SIPs into SOCs. Thus, web-based SIP e-Commerce mechanisms, called SIP Malls, have emerged, aiming to resolve complex SIP issues. To maintain its leading position and competitiveness in the World's IC industry, as well as the value added by SOC products in Taiwanese IC firms, the Taiwanese government has developed SIP Malls, using innovation policy tools. However, the Taiwanese SIP Mall industry remains immature. No existing Taiwanese SIP Malls generate a profit or account for a significant share of worldwide SIP transactions. This research will develop an analytical framework for defining an innovation policy portfolio that aims to develop Taiwan's SIP Mall industry, so that it will enhance the value added of SIP Malls and, thus, the nation's competitiveness in the SIP and IC industries, something which already has become one of the Taiwanese government's major concerns. The industry innovation requirements (IIRs) are summarized using the Delphi method. Meanwhile, the major IIRs identified by Decision Making Trial and Evaluation Laboratory (DEMATEL) are introduced. After the IIRs are derived, the relationships between the IIRs and innovation policy tools are derived by Grey relational analysis (GRA). Then, the innovation policy tools are clustered, based upon the Grey grades derived by GRA. Finally, reconfigured innovation policy portfolios are presented for the Taiwanese government's policy definition. The results demonstrate that developing an innovative policy portfolio that includes scientific, technical, educational, public enterprise, information, legal and regulatory, financial, and taxation policy tools will be the most necessary step towards developing Taiwan's SIP Mall industry.

一种灵活的ADO方式的SQL Server数据连接方法

在基于SQLServer数据系统的C/S开发中,大多数的开发平台与数据库的连接在应用中使用的是固定参数的连接模式,灵活性很差,对于服务器端的可维护性(如服务器更名,IP地址的改变,多数据库系统混合应用等)变得越来越弱,同时维护成本也随之提升,有的甚至服务器系统安装完毕后除了数据备份之外便一直不作任何变动,在安全性和数据库系统混合运用上形成很多不兼容的问题。本文提供了一种基于TCP/IP的客户机与SQLServer连接方法(使用VB开发环境描述),使得无论服务端还是客户端的维护和应用具备高度灵活性也便于安全性维护,同时这种方法也适应于广域网环境的应用。

“互联网+”背景下的IP模式

IP即知识产权。IP模式指围绕某一特定IP品牌进行多媒体开发的商业模式。IP是媒体重要的文化资本,它也提供了新型文化生产关系。传统媒体IP模式开发存在市场短板,但"互联网+"战略为传统媒体融合新媒体,为IP模式带来了新的契机。     

基于 TCP/IP 的远程数字监控系统

根据美国国家经济研究局（NBER）的最新宣布,美国经济自2001年3月已经进入衰退。本文认为,美国此次衰退是难以避免的,这是经济周期的必然规律,由于此前虚拟经济与实体经济的发展脱离,形成泡沫,那些过剩的资本终究会退出,于是造成人们心理预期的过度反应,消费和投资需求出现大幅萎缩,而恐怖袭击事件则加速了衰退的进程。对中国而言,美国衰退的影响是利弊兼有,主要表现在出口、引资、经济格局等方面。
