When considering the use of games for teaching mathematics, educators should distinguish between an "activity" and a "game". Gough (1999) states that "A 'game' needs to have two or more players, who take turns, each competing to achieve a 'winning' situation of some kind, each able to exercise some choice about how to move at any time through the playing". The key idea in this statement is that of "choice". This article describes a classic game called...

Recharging the battery system on Navy Autonomous Underwater Vehicles requires physical electrical contact between the vehicle and a docking station specifically designed to accommodate only one particular hull size. Inductive power transfer using mutually coupled coils eliminates physical contact, which can lead to an electrical short in a seawater environment, and provides the flexibility needed to create a docking station that can accommodate numerous hull sizes. Unfortunately, the...

We review concepts, principles, and tools that unify current approaches to causal analysis, and attend to new challenges presented by big data. In particular, we address the problem of data-fusion-- piecing together multiple datasets collected under heterogeneous conditions (i.e., different populations, regimes, and sampling methods) so as to obtain valid answers to queries of interest. The avail- ability of multiple heterogeneous datasets presents new opportunities, since the knowledge that...

Concatenating two or more strings together while developing a C++ application is a very common task. For CStrings, there are two primary ways to concatenate strings. The first is to use the += operator to concatenate two strings, and the second is to use the + operator. This report compares the two operations.

Several pressing issues in reading instruction have prompted educators world-wide to conduct researches on how to best improve reading comprehension skills. Although there is a wealth of reading comprehension researches done with EFL learners and native English speakers, there seems to be limited published studies conducted in the Philippine ESL context, particularly one that focuses on the sub-skills of reading comprehension. The researchers attempted to address the aforementioned by assessing...

While prostate cancers initially respond to androgen ablation therapy, tumors often become treatment resistant as tumor cells develop mechanisms to evade the treatment. Dysfunction of the androgen receptor frequently observed in castration resistant stages of prostate cancer. We reasoned that early knowledge of androgen receptor dysfunction can predict the course of prostate cancer progression. We proposed an approach for monitoring potential dysfunctions of the androgen receptor by measuring...

Locating and surveying underwater dumping sites of unexploded ordnance (UXO) is challenging, particularly when they are buried beneath the seafloor sediment. Low-frequency (LF) sonars have a demonstrated capability for detecting buried objects. However, high clutter densities observed in relevant operational environments will limit their use unless a capacity is developed to distinguish between clutter (e.g., natural objects, debris, and seafloor topography) and UXO. In this project, a...

This paper presents a multimodal discourse analysis of a story that has been turned into a Yoruba song-drama, highlighting the ideational, interpersonal and textual aspects of the song-drama. The data is a short song-drama meant to teach children importunity, determination and hard work through persistence. The multimodal and narrative conventions used for analysis according to Kress and van Leeuwen (2001), show the need for cooperation and determination in a world that is characterized by...

This thesis is motivated by biological experiments, which display the harbor seal's ability to track the wake of an object several seconds after it swam by. In this work, I elucidate the basic fluid mechanisms that seals may employ to accomplish this detection. Key are the unique vortex-induced vibration (VIV) properties resulting from the geometry of the harbor seal whisker. First, force measurements and flow visualizations on a rigid whisker model undergoing 1- D imposed oscillations show...

The project aimed to unravel the molecular mechanism of structure alteration and force generation of protein actuators called forisomes. The proteins undergo a rapid calcium induced ATP independent anisotropic contraction. We aimed to express recombinant forisome proteins in a cell free wheat germ system and crystallize the proteins for x-ray diffraction and electron microscopy. While expression of the proteins was achieved, the conditions in the wheat germ system prevented crystallization....
