the present sought to draw a comparison between model predictive control performance and two other controllers named simple pi and selective pi in controlling large-scale natural gas transport networks. a nonlinear dynamic model of representative gas pipeline was derived from pipeline governing rules and simulated in simulink® environment of matlab®. control schemes were designed to provide a s...

In late 2013, the Submarine Force decided to modernize the 1990's combat systems on OHIOClass submarines. In early 2014, as the Submarine Combat and Weapon Control Systems (PMS 425) Program Manager, I realized that due to the process we use for developing software and hardware, it would take until 2022 to modernize all SSBN combat systems. Based on this lengthy timeline, I challenged my team "H...

In coastal regions, the study of karst aquifers and the ground water resource exploitation require a specific methodology and exploration and monitoring techniques. Two directions are investigated, leading to new technological and methodological developments. The first investigation axis deals with the exploration of fresh water plumes from submarine karst springs. An Autonomous Underwater Vehi...

Our objective was to apply ideas from complexity theory to derive neurophysiologic models of Submarine Piloting and Navigation showing how teams cognitively organize around changes in the task and how this organization is altered with experience. The cognitive metric highlighted was an electroencephalography (EEG)derived measure of engagement (termed NS_E) which was modeled into a collective R....

In 1929, an earthquake off the Grand Banks of Newfoundland initiated a submarine mass movement that sheared undersea communication cables and generated a tsunami that resulted in deaths of 27 people along the south coast of Newfoundland. This event initiated the modern realization that the seafloor is a dynamic environment with potential to do harm. More recent catastrophic examples include sub...

Exploratory in nature, this study was designed to identify some of the personality trait configurations and attitude change patterns related to individual differences in cold coping capacity (CCC). Three enlisted marines participated in a week-long cold weather North Atlantic Treaty Organization (NATO) combat exercise in upper Norway. The Minnesota Multiphasic Personality Inventory (MMPI) was a...

127 Bergsten Abstract We describe how specialized database technology and data analysis methods were applied by the Swedish defense to help deal with the violation of Swedish marine territory by foreign submarine intruders during the Eighties and early Nineties. Among several approaches tried some yielded interesting information, although most of the key questions remain unanswered. We conclude...

in this paper, the behaviour of buried pipelines under the effect of propagation of seismic waves and faulting is studied seperately. the stability of this type of structure was first studied by using three different methods proposed by newmark-hall, kenndey et al. and wang - yeh under the effect of ground faulting. by parametric study, the effect of soil types, size of pipeline, depth of embed...
