This paper defines and further explains what it refers to as the curse of dimensionality. This concept was identified and defined by Bellman and refers to "the exponential growth of hypevolume as a function of dimensionality." The paper also offers another explanation that is considered more extensive. i
From the Paper
"The curse of dimensionality was identified and defined by Bellman (1961), referring to "the exponential growth of hypevolume as a function of dimensionality" (Sinkonnen 2007, para. 1). Another explanation that is more extensive is offered by a website at UCLA (2001), stating that in "statistics it relates to the fact that the convergence of any estimator to the true value of a smooth function defined on a space of high dimension is very slow" (para. 2). Essentially, the concept holds that high dimensional data is hard to work with because adding more features can increase the noise and so the rate..."

Abstract
It has been well established that blind people are capable of identifying haptic pictures. However, the mechanism by which this operates is less clear. This essay reviews research that has been conducted into the way in which blind people identify haptic pictures. It reviews research which shows that blind people are better at identifying haptic pictures using manual exploration, and that the congenitally blind are better than the late blind. It also reviews research which compares bimanual exploration with unimanual exploration.

Abstract
This paper discusses the characters of Margaret Atwood's novel, "The Robber Bride." It analyzes the four principle characters individually and suggests that they are ones of psychological validity because they are tangible and allow the reader to deeply explore and dive headfirst into their lives of hardship, suffering, and remorse. The paper also briefly looks at the plot through the characters.
From the Paper
"Zenia herself remains a high-concept construct throughout the novel: as various reviewers have noted, she lacks all substance and credibility, particularly beside the solidity spun around each of the protagonists. But the hollow vessel Zenia remains is exactly the point. Atwood has alluded to the Jungian overtones of the novel, and in particular has described the mythic villainess upon which she has based Zenia as a "shadow" figure for female readers as well as for her fictional comrades. As such, Zenia serves as a canvas onto which the darkest fantasies of those who encounter her can be projected, with no foundation character in place to counteract such fantasies (Mycak 12-16)."

Abstract
Educational Leadership historically depended upon Educational Psychology for assessing the individual's personality traits in determining "who" would make a good school leader. The problem with personality and trait-based measurements, however, emerged in the difference between pencil-and-paper test performances, and interactive social behaviors, which often contradicted each other. As the ideas of school culture emerged with the introduction of Anthropology's understanding of "culture," school leadership was re-conceptualized towards a cultural and social-based understanding of inter-active participants with values and interests that required inclusivity in the school's community. As personality was regarded less and less relevant to educational leadership, sociality and communicative skills were regarded as more valuable, as were abilities in negotiation, compassion and patience. This has produced a multi-dimensional approach to educational leadership, where all levels of school activity, including the school's relation with its community, are included in understanding what it required of an educational leader.

Abstract
This paper examines the four sisters, their parents, the political backdrop, and the Dominican Republic's male-female nexus, which is so different from what one has come to view in America. The author points out that, in "How the Garcia Girls lost their Accent", which is set from the early 1960s to the mid 1980s, each sister brings her own dimensionality, which is a slice of what constitutes a woman. The paper states that the sisters' accents have completely changed; but, for better or worse, they have been fully assimilated into American culture.
From the Paper
"It is in Fifi's relationships with men that we see the most vagaries. The start of the novel shows that she is really a person who would support a stable family. She is headstrong and independent. She generally gets what she wants. She presents her parents with their first grandchildren a boy. She is the only one among her siblings that does not have a college degree, though there is no lack of intellect. Her husband is the most accomplished of all " the German nobody turned out to be a world class chemist."(p. 31) She seems to hold equal say in her marriage though her husband's character is not explored. Surprisingly, Fifi can adopt different roles."

Abstract
This paper explains that, although Henri Matisse and Picasso are noted as two of the greatest artists of the 20th century, Matisse, whose career spanned many decades, was always humble about his art especially his origins as an artist. The author points out that his work did not show natural items; instead, he attempted to capture emotions, sensations and the experience of his subjects, which very often took on a life of their own and looked more like caricatures rather than real subjects. The paper relates that Matisse is know for his vivid colors and one-dimensionality as seen in his paintings "The Blue Nude" and "The Red Studio".
From the Paper
"In "The Red Studio," Matisse's use of color, imagination, and freedom of expression are all abundantly clear. In the one-dimensional work, detailed paintings clutter the walls, giving a sense of space and yet seeming closely confined at the same time. That is one very interesting aspect of Matisse's work throughout his career. His work was all flat and one-dimensional, and yet it did not seem flat or uninteresting at all. Critic Danto continues, "In 'The Red Studio' we see a corner, but the color of the walls, which meet at right angles, is uniform, as if they stood in the same plane."

Abstract
In this article, the writer looks at the characters Dorian Gray in "The Picture of Dorian Gray" and Dr. Faustus in the play of the same name. The writer notes that in both Marlowe's and Wilde's tales of men overreaching the natural order, evil is primarily construed as transcending the natural, specifically of desiring eternal life, rather than bowing to the natural processes of change that are inherent in nature. Further, the writer points out that God's law is synonymous with nature, and both Faustus and Dorian Gray go against nature and embrace artifice and art. The writer concludes that for all of their unnaturalness and evil, the protagonists remain the most 'naturally' compelling characters of their respective dramas, given the unrealistic and 'unnatural' one-dimensionality and weakness of those individuals who are unfortunate enough to encounter Dorian and Faustus.
From the Paper
"The seductiveness of both protagonists' ambitions for the reader, however, has provoked contradictory interpretations in the responses of critics and its more general audience. On one hand, both works seem to argue that obeying God's natural order and law regarding knowledge and morality is best. In short, do not seek to become a magician or seek to be young forever. But although Dorian Gray may read like an argument against art and artifice on one hand, it itself is a work of art. Furthermore, although "Dr. Faustus" argues against magic, the actors on the stage need to make use of 'magic' to portray the morality tale of the fall of the scholar from Wittenberg. This confuses the question of what is good or bad in both plays, especially since the 'good' characters like the old man who counsels Faustus to repent, or Basil and Sybil in Wilde's work, are the weakest characters."

Abstract
This paper examines the impact of newly integrated computer-aided design (CAD) systems in improving safety factors in the aviation industry by looking at where it can be improved. The paper looks at how CAD has incorporated the human factors principle - that is, the type of people who use the technology - into the design-making process. The paper explains that on the whole, CAD technology is an enormous improvement over older aviation design because it allows designers to visualize situations in three-dimensionality throughout the design process. CAD can provide a very good visualization overview of human interaction with the product (in this case, the pilot user interface of a cockpit). The paper also explains that CAD technology is an excellent tool for designing pilot user interfaces because it saves time and money, and CAD technology is infinitely superior to the research tools that preceded it, because it allows designers to see hypothetical human reactions to environmental stimuli in three dimension. The paper then points out that, CAD is not so intuitive that it can anticipate every conceivable human reaction that might result from a particular situation. The writer believes, therefore, that there remains a need for live testing with actual people.

From the Paper
"Whenever a study examines new technology, there will be some limitations. Today, CAD technology offers the promise of creating cockpit devices that will accommodate pilots of every skill level and idiosyncrasy; although a CAD-based ergonomic analysis program allows for the creation of accurate, 3-D human models, it seems extremely unlikely that any computer program can truly simulate the enormous range of abnormal responses that can be expected of different human beings. Therefore, human subjects are desirable in assessing the effectiveness of different products within the cockpit - and finding an appropriate sample group is not easy. It is extremely difficult to assemble a representative sampling of different pilots (in simulated conditions, of course) with the intent of measuring the capability of CAD in avoiding in-air tragedies."
