Leachable and dislodgeable arsenic and chromium from CCA (chromated copper arsenate)treated wood were studied to evaluate the fate of these CCA-chemicals and possible human exposures when the chemicals have been released to the environment. To evaluate the leachable component, two full sized decks were constructed. One was made of CCA-treated wood, and the other was made of untreated wood. Rain...

The purpose of this study is to provide evaluation data to examine and verify the effectiveness of the materials through physiological comparison and analysis of the new prototype snowboard deck with the existing equipments. In order to achieve the purpose, blood lactate concentrations and energy metabolic variables were measured from the targeted snowboarders. Five male snowboarders (Slope-sty...

Card shuffling is an interesting topic to explore because of its complexity. Initially, card shuffling seems simple because it is ubitquitous. The majority of people know how to shuffle a deck of cards but few consider the math behind it. However, when it comes to analyzing the elements of card shuffling, it incorporates linear algebra, group theory, probability theory, and Markov Chains. When ...

Research has shown that cognitive load affects overall Iowa Gambling Task (IGT) performance, but it is unknown whether such load impacts the selection of the individual decks that correspond to gains or losses. Here, participants performed the IGT either in a full attention condition or while engaged in a number monitoring task to divide attention. Results showed that the full attention group w...

This quarter we modified the database to account for the ship classification and ship counting guidance in the Secretary of the Navy’s Instruction 5030.8A [3]. First, we inserted four new fields: 1. 5030.8A Force Category – “Battleforce” or “Non-Battleforce.”1, 2 2. 5030.8A Ship Category – “Combatant Ship,” “Auxiliary Ship,” or “Combatant Craft.” 3. 5030.8A Ship Classification – For example: “W...

To reduce water traffic accident, identification of overloaded ships has been of major importance for enforcing inland river management, especially in some developing countries. Driven by rising oil prices or other economic benefits, the ship overload phenomenon continued to occur in China. Therefore, overloaded ship detection has been of a key factor of shipping safety. This paper presented a ...

A flight deck display that allows the pilot to “see” the neighboring aircraft, as well as its wake, may allow for a decrease in spacing and an increase in airport and airspace capacity, while maintaining safe separation distances from wake vortices. This research evaluates a model based on aircraft parameters that are readily available in flight to predict aircraft wake vortices in real time. U...

A time domain method is presented to identify the moving loads on the bridge deck from measuring strains. The bridge deck is modelled as a rectangular orthotropic plate. The vehicle is modelled as two axle loads moving on the bridge deck. Like all inverse problems, the identification is an ill-posed problem, so a regularization technique is employed to stabilize the solution. This paper gives a...

Let Va be the element (defined more precisely in the paper) of the group algebra Q(S n ) which describes the action of taking the first a cards out of a deck of n cards and then inserting these cards back into the deck either upright or flipped. We prove that
