Abstract Attacks on industrial control systems remain rare overall, yet they may carefully target their victims. A particularly challenging threat consists of adversaries aiming to change a plant's *process flow*. A prominent example of such a threat is Stuxnet, which manipulated the speed of centrifuges to operate outside of their permitted range. Existing intrusion detection approaches fail to address this type of threat. In this paper we propose a novel network monitoring approach that takes process semantics into account by (1) extracting the value of process variables from network traffic, (2) characterizing types of variables based on the behavior of time series, and (3) modeling and monitoring the regularity of variable values over time. We implement a prototype system and evaluate it with real‐world network traffic from two operational water treatment plants. Our approach is a first step towards devising intrusion detection systems that can detect semantic attacks targeting to tamper with a plant's physical processes.

What distinguishes the AGI approach from the initial, supposedly equally idealistic and holistic, AI approach? Why do we think that we could make any progress in our recent times? The answer to these questions is not clear

: The paper presents the life cycle cost structure of a newly designed office building where the costs of planning, construction, operation and maintenance are analyzed for time periods of 20 and 30 years according to current market prices and reduced to net present value. The results of the life cycle cost analysis show that for a period of 20 years, the shares of initial or capital costs and operation and maintenance costs are approximately equal. For a period of 30 years, the share of capital costs is 42.6%, and the share of operation and maintenance costs is 57.4%, which exceeds capital costs. These results confirm previous research and the significance of the operation and maintenance costs, and indicate that in engineering practice in the design stage it is necessary to analyze and calculate the total costs of the life cycle of buildings for the purpose of evaluating variant solutions
