ABSTRACTA variety of Cu/(Ni, Co) multilayers have been grown on Cu single crystals by pulse plating from an alloy electroplating bath. Copper is deposited under mass transport control while the iron group metal is deposited under interfacial charge transfer control. The structural evolution of these films is influenced by the morphological instability of the mass transport limited copper deposition reaction and the development of growth twins during iron-group metal deposition. Specular films have been obtained for growth on Cu(100) while rough, defective films were typically obtained for growth on Cu(111) and Cu(110).

Control center operations are highly demanding in terms of the collaboration required for monitoring and decision making in teams. In a joint effort led by the DLR, several institutions investigated psychological requirements among teams in control centers. This involved holding workshops and shadowing the work of experts for operative processes in control rooms of several industry partners (Deutsche Flugsicherung GmbH, Deutsche Lufthansa AG, Flughafen Hamburg GmbH, Hamburger Hochbahn AG). An initial control room resource management (CRRM) training was developed and tested with a group of operators from the Galileo Control Center (GCC). The refined version of the 2-day CRRM training was developed for groups of 10-12 participants and was validated in seven training sessions with a total of 79 operators from the subway control center of the Hamburger Hochbahn AG. In conclusion, the CRRM training provides a successful approach to improve teamwork in control rooms.

Various methods of collecting data on passenger traffic, their advantages and disadvantages are considered. It is shown that in order to improve the quality of transport services, it is necessary to regularly collect and refine data on passenger traffic. The goals and methods of obtaining information about passenger traffic in the system of municipal passenger transport are indicated. All currently existing methods are divided into three categories: data collection using technical means, data collection with the help of censors and volunteers, and interpretation of fare payments. All the methods presented in the article were compared in terms of labor intensity, costs and accuracy of the results obtained. The advantages and disadvantages of each method are considered. The general structure of an automated system for collecting data on passenger traffic is presented. The necessity of creating a centralized system for collecting and processing data associated with all passenger transport control systems has been substantiated. The tasks solved by this system at all levels of transport services for passengers are shown. Each of the tasks is assigned to one of three service levels: pre-transport, transport and post-transport. It is shown that only solving problems at all levels can ensure high-quality operation of the municipal passenger transport system.
