Construction Industry operates relying on various key economic indicators. One of these indicators is material prices. On the other hand, cost a concern in all operations construction industry. In uncertain conditions, reliable forecasts become an important source information. Material one components overall construction. addition, overrun common problem industry, where nine out ten projects fa...

This paper discusses an R & D project selection and scheduling problem in which there are no historical data about the project parameter values. The net income and investment cost in the problem are given by experts’ evaluations and treated as uncertain variables. The different interactions among projects and the flexibility of project beginning time are considered. A new cost overrun risk is e...

We investigate theoretically the effect of a finite electric field on the resistivity of a disordered one-dimensional system in the variable-range hopping regime. We find that at low fields the transport is inhibited by rare fluctuations in the random distribution of localized states that create high-resistance breaks in the hopping network. As the field increases, the breaks become less resist...

World War II began on September 1, 1939 with the German invasion of Poland. By early May 1940, German troops had overrun the Netherlands, Belgium, and Luxembourg; soon thereafter Germany broke through the French defensive forces near Sedan. Political lethargy, a poor communication system and many mistakes accelerated the downfall of the French army. By the end of May approximately 350,000 Frenc...

Our goal is to utilize living microorganisms as smart, autonomous microrobots. In previous work, we constructed a dynamics model of Paramecium cells for navigation using galvanotaxis (locomotion response to an applied electric field). In this paper, an overrun phenomenon, which affects the control performance, is evaluated using the proposed dynamics model, and it is found that the turning traj...

We live in a culture that, for many historical and economic reasons, pathologizes many of the normal processes and responses of human growth and development— especially for women. The cultural reasons for this are deeply embedded in a 6,000 year-old process of systematic overrun of indigenous peoples by a culture based on exploitative, empire-building patriarchal values. Daniel Quinn, in his aw...

Historians of science Naomi Oreskes and Erik Conway, authors of Merchants of Doubt, have written a new book as ambitious as it is concise. The Collapse of Western Civilization: A View from the Future is told from the perspective of a Chinese historian several centuries in the future, looking back at our current time and attempting to explain to readers the irrationality of our behavior. In the ...
