Show moreThere continues to be significant growth in the development and use of speech–mediated devices and technology products; however, there is no evidence that non-native English speech is used in these devices, despite the fact that English is now spoken by more non-native speakers than native speakers, worldwide. This relative absence of non-native English speech in devices may be due in part to the costs associated with localizing speech devices, but it may also be attributable to the fact that not enough is known about user performance with accented speech in speech–mediated environments. In the absence of targeted research, developers may be relying on existing studies which focus on perception (impression) of accented speech, as a basis of decision-making. However, perception paints only part of the picture when it comes to understanding how and why people perform in certain ways and in certain environments. Three studies were conducted to answer the following questions: (1) What are the acoustic-phonetic characteristics of negatively- and positively-perceived accented speech? And how are these characteristics related to markers of intelligible speech? (2) How do participants perform on different types of accented-speech tasks? (3) What is the relationship between user perception of accented speech and user performance in response to accented speech? and; (4) How do participants perform on accented speech tasks of varying complexity? Arising out of this research, there are six recommendations for the use of accented speech in speech-mediated devices. Also, the findings of this study raise questions about inherent linguistic stereotypes which impact both our perceptions and our choices about xvi the accents we want to hear on our speech devices. A discussion about if and how these stereotypes can be altered and measured are included. Future research should examine the role of experienced non-native talkers in speech devices. Results of study one demonstrated that some experienced non-native talkers were positively-perceived by raters and may be good candidates for talkers in speech devices. A study like this would explicitly establish if listeners consistently make native vs. non-native distinctions in their preferences or if a prestige continuum emerges.

Show moreIndia’s huge and growing population is putting severe strain on all of the country’s natural resources. Most water sources are used on a domestic, industrial and agricultural basis. The quality of the water used is presumed to be the major problem that the people face, but the real problem is the quantity of water supplied. Quite a few organizations have been engaged with supplying drinking water to the community, but still not enough to address the needs of all the different sectors of the community, especially irrigation. In order to increase the availability of water to the people, it is necessary that the people have alternative means of supply of water, and a strong sense of the value of water.

Show moreThe overall conflict that IPRO 313 is trying to resolve is the dependency on oil as a fuel source for automotive vehicles. Along with the global and financial concerns that go along with oil as a fuel source, there has been growing interest in electric vehicles. Electric vehicles are the competitive issue that IPRO 313 has researched, investigated, and is working to resolve. Currently, most electric vehicles run on lithium batteries. The problems associated with these vehicles are the recharge time and service station compatibilities. The most popular electric vehicle is the Testla Roadster, which has a driving distance of approximately 270 miles per full charge. Although this is an adequate driving distance, it takes six to eight hours for a full charge. This amount of charge time is a vital drawback for electric vehicles. The vast majority of service stations are not electric vehicle friendly. Gas stations do not and have not set up areas for electric battery pack replacement, or vehicle charge. Withou

Show moreIPRO 340 (The Idea Fermentors) is working with Rock Bottom Brewery to determine alternative uses for the spent grain the brewery produces. Over 1,000 pounds of spent grain are produced at each of the three area locations weekly. Spent grain has many applications because of its high content of protein and fiber. Applications range from production of bio-plastics and bio-fuel, to agricultural uses as animal feed and compost material, to reuse as food for people. A major issue that Rock Bottom Brewery faces is that spent grain spoils very quickly, so alternative uses of spent grain must happen within a matter of days. IPRO 340 will determine what will be the best use of Rock Bottom Brewery’s spent grain in terms of logistics, cost, practicality, and environmental impact. The Idea Fermentors will lean and understand the brewery process and various applications for spent grain, as it pertains to Rock Bottom Brewery. The team will work together to accomplish project requirements as set forth by the IPRO office at IIT on time as well as satisfy the sponsor company’s needs.

Show moreThe goal of this project is to assist our client, the Lugenia Burns Hope Center, expand an already-established parents organization serving seven of Bronzeville's public schools: Doolittle West, Dootlittle East, Raymond, Abbot, Donahue, Wells-Prep, and Mayo. This organization P.O.W.E.R. for our kids (Parents Organization Working for Educational Responsibility for our kids)--is an independent network of parents and community organizers working in concert with the Local School Councils to improve student achievement and educational opportunity. Our team will create promotional literature advertising the cause of the union, research the problems in the schools, and propose changes to the curriculum and the culture of the schools, which members of POWER and the local school councils can implement. This project gives students in the Leadership Academy an introduction to grass-roots, community organizing. Students involved with Math/Science education and the Young Women's Charter School might join the team to advise our client on best classroom practices. Students of public policy, law, political science, and architecture would be challenged to place the problems of the schools within the context of city, state, and federal policies on education, housing, land-use and other aspects related to the vitality of healthy neighborhoods. Should students of psychology join the project, they might help the team understand those aspects of human motivation and behavior required for building of human capital in low income communities. And, of course, students of technical communication, design, and internet communications, finally, would not only be valuable additions to the team because of their interests in web site and document design, but because of their interests in constructing persuasive texts. In general, students with an interest in making a difference in the surrounding, IIT community would have an opportunity to work with community leaders who likewise want to see Bronzeville's public schools better serve their children.

Show moreWomen and men communicate differently in both face-to- face and computer-mediated environments. We study linguistic patterns considered gendered in reviews contributed to the Internet Movie Database. IMDb has been described as a male-majority community, in which females contribute fewer reviews and enjoy less prestige than males. Analyzing reviews posted by prolific males and females, we hypothesize that females adjust their communication styles to be in sync with their male counterparts. We find evidence that while certain characteristics of “female language” persevere over time (e.g., frequent use of pronouns) others (e.g., hedging) decrease with time. Surprisingly, we also find that males often increase their use of “female” features. Our results indicate, that even when they resemble men’s reviews linguistically, women’s reviews still enjoy less prestige and smaller audiences.

Finkl & Sons (Chicago, IL), a substantial amount of time and money is lost due to the fact that cutting inserts break catastrophically and without warning. The goal of this project is to devise an effective means by which a cutting insert breakage event can be quickly and reliably detected, thereby minimizing damage to the steel and other cutting inserts, and also freeing technicians to attend multiple machines at a time. This increases the productivity of their operations, and it has the potential to save A. Finkl & Sons substantial costs per year in time lost in rework and prematurely broken cutting inserts.

Show moreHuman norovirus (HuNoV) is considered an important cause of foodborne outbreaks, often attributed to the preparation of fresh produce by infected food handlers. In this investigation, methods for recovery of murine norovirus (MNV-1), a surrogate for HuNoV, from food preparatory surfaces were optimized, and MNV-1 crosscontamination between various surfaces common in a food service setting were studied. Fifty microliters of MNV-1 was inoculated onto demarcated 1 x 1 inch squares of polypropylene cutting board, stainless steel knife and spigots. After drying, MNV-1 was recovered from each surface using either a cotton swab, composite tissue or sterile sponge in combination with different eluents such as tissue culture growth medium, 3% beef extract, glycine buffer (50mM glycine, 1% beef extract), stripping solution (0.04% K2HPO4, 1.01% Na2HPO4, 0.1% Triton X-100), and Earle’s Balanced Salt Solution (EBSS). The eluent/recovery tool combinations that recovered the highest percentage of MNV-1 from cutting board were stripping solution/sponge (20%) and growth medium/swab (20%). The greatest recovery from the knife blade was achieved with the growth medium/composite tissue combination (43%), while recovery from spigots was greatest using the stripping solution/sponge (28%) and the growth medium/sponge combinations (27%). In the second phase of this investigation, human volunteers were asked to perform various tasks in order to quantify the amount of MNV-1 cross contamination between various surfaces, including bare hands, fresh-cut lettuce, and spigots. The percentage of MNV-1 transfer from hands to spigots varied from 0.06% to 3.59%, spigots to hands varied from 10% to 90.4% and lettuce to hands varied from 0.30% to 4.33%. x The results of this investigation can be used in developing a model describing the transfer pattern of HuNoV between surfaces common in retail food service, and used in developing educational materials for food service workers.

Show moreWe would like to develop a system that measures the applied torque at a bicycle crank set. In contrast to current solutions, we want to be able to retrofit our system to existing crank sets, obviating the need to abandon parts that the bicyclist already owns. In principle, according to preliminary tests performed at the MMAE department, this can be done using sets of quite inexpensive strain gauges. However, being able to get accurate torque measurements will require some advanced signal processing from the strain gauges. These signals can then be transmitted wirelessly to a bicycle computer like the Edge 705 that the global positioning system corporation Garmin released last year. There is a defined wireless protocol, called ANT+Sport, which has been developed specifically for the purpose of transmitting exercise data, such as power output or heart rate, to small computers. Chipsets and development kits for this protocol are also available commercially. Therefore, our task will be to find an optimal configuration of strain gauges that will be attached to the crank set, and to develop an algorithm to process the strain gauge data in order to isolate a signal that is proportional to the applied torque. This signal will then be transmitted to the bicycle computer for display and storage.
