Warehouse Management System

A warehouse management system using the three-dimensional location tracking and positioning system based on time-of-flight principle is presented in this paper. Integrating three distance measurement sensors and computer programming to process the signals obtained from the sensors, the system can capture, store, and retrieve the three-dimensional position of steel coils located in a warehouse in real time. Updated information will also be stored in a database as a backup. Experiment shows that the system designed in this paper has the merits of real-time tracking of steel coils stored in a warehouse, or any uniformed storage locations.

Abstract Real-time detection of extracellular hydrogen peroxide is important for dynamic monitoring of diseases and cytopathological research. Here, a novel composite of Fe-hemin-metal organic frameworks/three-dimensional graphene (Fe-hemin MOFs/3DG) was prepared by embedding hemin into amino-contained Fe-MOFs, then decorated with 3DG. The obtained Fe-hemin MOFs/3DG possessed efficient peroxidase-like bioactivity and could serve as an effective catalyst for construction of H2O2 electrochemical sensor. The electrochemical results show that the proposed sensor based on Fe-hemin MOFs/3DG has excellent catalytic activity for H2O2. With a linear range was 10 - 12080 μM and LOD was 0.34 μM, this sensor showed favorable selectivity, repeatability and stability, which could be used to detect H2O2 in real serum samples. Most importantly, this sensor realized the real-time determination of H2O2 released by A549 cells and possessed good biocompatibility. The outstanding electrochemical performance mainly benefited from the unique porous structure of MOFs, which could effectively protect the active center of hemin, and the introduction of 3DG greatly improved the conductivity of Fe-hemin MOFs. Therefore, the Fe-hemin MOFs/3DG could be a promising probe for real-time dynamic monitoring of H2O2.

Basic Services

Underground utilities are important assets that provide basic services for society’s daily life. They are generally very complex and remain unnoticed until they fail due to any particular reason. The stakeholders involved in the design, construction, and maintenance of utility infrastructure face many problems due to the traditional underground utility management system, resulting in injuries, loss of life, disruptions, project delays, and financial loss. The problem with the traditional system is that it uses 2D drawings and keeps unreliable information or a lack of updated information, which makes it an inefficient utility management system. With the advancement in construction information technology, we can address this effectively by integrating BIM and GIS. In this paper, a novel integrated BIM-GIS framework for underground utility management systems was developed on the basis of IFC to CityGML mapping. It provides an effective underground utility management system that facilitates designers in optimization of the design, assists in the excavator’s operator by providing real-time three-dimensional spatial information during the construction process, and acts as an as-built information database for utility facility management. For validation, a real-time project case study indicated that the proposed system can effectively provide comprehensive underground utility information at different project stages.

Database Technology

Web-based network management revolving about database puts forward a feasible mode for network information processing and has the characteristics of wide distribution, full interactivity, real-time dynamic and so on in the application; and is beneficial to timely adjustment for network performance and rapid recovery for fault. Combining the technologies of JSP, JavaBean, JDBC, Socket, JavaApplet, Ajax, JavaScript and so on, database-centric network management mode ensures the reliable, efficient and stable operation of configuration, performance, fault, security and accounting management in the development of business network management system, such as TD-SCDMA network, PON network, TMPLS network, IPTV network, power network and so on. In practice, it is worth mentioning that it improves the dynamical and real-time release performance of accounting management, realizes web-based management for rate and bill. Customers could receive bills real-timely in internet and deals with them conveniently. This is propitious to the management of network vendors as well.
