As an important support for quantum communication, quantum key distribution (QKD) networks have achieved a relatively mature level of development, and they face higher requirements for multi-user end-to-end networking capabilities. Thus, QKD networks need an effective management plane to control and coordinate with the QKD resources. As a promising technology, software defined networking (SDN) can separate the control and management of QKD networks from the actual forwarding of the quantum keys. This paper systematically introduces QKD networks enabled by SDN, by elaborating on its overall architecture, related interfaces, and protocols. Then, three-use cases are provided as important paradigms with their corresponding schemes and simulation performances.

A new concept of using a PV solar power plant as interline PV system is introduced in this paper. As the name suggests, the interline PV system interconnects two (possibly more) transmission/distribution lines by reconfiguring existing PV solar plant inverters. This newly developed system thus can act as a FACTS device providing a flexible control over both active and reactive powers on multiple lines simultaneously.

Control And Management

To solve the problems of unstable process, frequent change and difficult management in assembly process of complex products, by introducing the workflow technology, the reverse process flow was defined based on analysis of assembly process execution and feedback process. The information model of process feedback was presented and a workflow based assembly process control and management method was proposed, and the real-time feedback of technology problems in workshops, the automatic running of reverse process as well as the assembly BOM based integrated management of process information were realized. The feasibility of proposed method was proved by actual engineering applications.

Control And Management

Proceed with manual work, materials and machinery, non-quantification risk factors control and management method of bridges during construction is studied. The results indicate that the key of controlling unquantifiable risk factors lies on supervision of careless mistake and accident, making clear responsibility, preparing measures of remediation for problems that may occur and minimizing negative influence of project risk by subjective factors which can be controlled. Research achievement can ensure bridge construction quality and safety, and then provide technical contribution.

Abstract. Background: We present the methods and results of the surgical management of extracranial carotid artery aneurysms (ECCA). Postoperative complications including early and late neurological events were analysed. Correlation between reconstruction techniques and morphology of ECCA was assessed in this retrospective study. Patients and methods: In total, 32 reconstructions of ECCA were performed in 31 symptomatic patients with a mean age of 59.2 (range 33 - 84) years. The causes of ECCA were divided among atherosclerosis (n = 25; 78.1 %), previous carotid endarterectomy with Dacron patch (n = 4; 12.5 %), iatrogenic injury (n = 2; 6.3 %) and infection (n = 1; 3.1 %). In 23 cases, intervention consisted of carotid bypass. Aneurysmectomy with end-to-end suture was performed in 4 cases. Aneurysmal resection with patching was done in 2 cases and aneurysmorrhaphy without patching in another 2 cases. In 1 case, ligature of the internal carotid artery (ICA) was required. Results: Technical success defined as the preservation of ICA patency was achieved in 31 cases (96.9 %). There was one perioperative death due to major stroke (3.1 %). Two cases of minor stroke occurred in the 30-day observation period (6.3 %). Three patients had a transient hypoglossal nerve palsy that subsided spontaneously (9.4 %). At a mean long-term follow-up of 68 months, there were no major or minor ipsilateral strokes or surgery-related deaths reported. In all 30 surviving patients (96.9 %), long-term clinical outcomes were free from ipsilateral neurological symptoms. Conclusions: Open surgery is a relatively safe method in the therapy of ECCA. Surgical repair of ECCAs can be associated with an acceptable major stroke rate and moderate minor stroke rate. Complication-free long-term outcomes can be achieved in as many as 96.9 % of patients. Aneurysmectomy with end-to-end anastomosis or bypass surgery can be implemented during open repair of ECCA.
