This manuscript describes the “smart” control system designed for a geothermal bridge deck heating system. The control system integrates concepts of model predictive control with a first-principles bridge deck model and hourly computerized National Weather Service (NWS) forecasts to prevent bridge icing without the use of salt or other chemical de-icing materials. The proactive nature of the co...

The most used life-line structure of the modern day is the bridges, which has been developed significantly, with the most recent introduction being of the curved bridges. They provide an aesthetic look and are also very convenient at various crossings and cross-over. However, curved bridges have been observed to have poor seismic response. Pounding between the adjacent segments, in-plane deck r...

Magic: The Gathering (MTG, or Magic) is the oldest and most popular trading card game played today, due in part to the complex interplay of thousands of cards. In two-player games, each player constructs a "main" deck (referred to as simply 'deck' hereafter) which consists of 60 cards, allowing players to pursue an enormous number of strategies and card combinations. When experienced Magic play...

In this paper, nonlinear implicit finite element analyses are used to explore parametric excitation of a bridge stay cable resulting from cyclic motion of the deck. “Parametric excitation” is excitation of a cable mode with deck motion at near twice the frequency of the excited mode. Third-mode parametric frequency response curves are consistently predicted when the finite element mesh is suffi...

In the near future, unmanned aerial vehicle (UAV) and unmanned ground vehicle (UGV) usage will expand into the Naval aircraft carrier operating environment. The new and different capabilities of these vehicles will likely introduce numerous potential changes in the nature of deck operations. The presence of UAVs and wireless data communications will enable centralized planning and control of la...

This article provides a review of Pear Deck which allows teachers to create interactive slide presentations. In this article, we first provide an overview Decks’ features and some background information about tool. Then, discuss its technological as well pedagogical features. Next, evaluate the teacher fit in terms theoretical underpinning tool how it can support student learning. We underline ...

There is a concern with worldwide deterioration of highway bridges, particularly reinforced concrete. Due to the corrosive nature of steel re-bars used in concrete bridge decks, the service-life of these bridges is reduced. The advantages of advanced composite materials (ACM) over conventional materials motivate their use in highway bridges for rehabilitation and replacement of structures. Howe...

A classic experiment used in testing for ESP abilities has the following general form. A deck of cards, consisting of a, identical cards of type i, 1 I i I r, is shuffled and placed face down (in most such experiments r = 5 and a, = 5 for 1 I i _( 5). The subject then attempts to correctly guess the type of each card as the cards are sequentially removed from the deck. In previous work [2,3], s...

BACKGROUND In their working activity, seafarers are exposed to high levels of stress that should be accuratelyinvestigated, measured, followed up and, if possible, countered. This is also required by regulations recently entered into force such as the Maritime Labour Convention 2006, recommending to consider special physiological or psychological problems created by the shipboard environment. T...
