Photovoltaic solar panels are now being manufactured via various methods, and different printing processes are being incorporated into the manufacturing process. Screen printing has been used most prevalently in the printing process to make solar cells, but some companies have used the offset web press type methods to put material onto foil; they also have created solar cells with inkjet printing. The printing of solar cells has helped to reduce manufacturing costs in most cases, and it also has increased the various applications in which solar power both is and can be used. Many more options for photovoltaic solar panels are available, and not simply the traditional ones that are often placed on rooftops. Such a variety of solar panels are partially to the result of the implementation of suitable printing processes during the production of these cells. Introduction With ever-increasing political and economic oil conflicts as well as climate change, a growing need for renewable energy that comes from natural resources, such as sunlight, wind, rain, tides, and geothermal heat, is warranted. Wars have been caused in part to protect oil supplies, and millions of tons of pollutants and greenhouse gases are emitted into the atmosphere every year due to the burning of fossil fuels to create energy. There is no other area of technology than renewable energy technologies that can both “meet the challenges of climate change and secure an energy supply in an intelligent manner” (Wengenmayr & Bührke, 2008, p. 1). A number of options for new technologies of renewable energy exist, that is, from geothermal to wind to hydrogen fuel cells to hydropower; however, one of the most accessible and widely used technologies is solar energy. Solar power does not create any noise when it is working, “is non-polluting, does not generate greenhouse gases, and creates no waste products,” (Brenner, 2010, p. 27), which is also why it is an increasingly preferred renewable energy. Additionally, the potential for solar power is immense. The energy from the sunlight that strikes the earth for only forty minutes is equal to the global energy consumption for an entire year (Zweibel, Mason, & Vasilis, 2008). All of that energy is of no use, unless it can be captured. A good method to harness this immense amount of energy and thus to eventually use it as electricity is through the use of photovoltaic (PV) energy systems.","PeriodicalId":142452,"journal":{"name":"The Journal of Technology Studies","volume":"559 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116276024","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A net zero energy home (ZEH) produces as much energy as is consumed in it over time. Students in a College of Technology in a Midwest Indiana State University and a technical University in Switzerland resulted in developing models of homes that combined U.S. and Swiss standards. The project was completed in two phases: during the first phase of this project, construction costs, energy use, and economic payback was calculated for six homes that were designed using both Swiss and U.S. standards. During the second phase of the project, cultural norms that influence energy use were explored. A survey was used to compare U.S. and Swiss college students’ lifestyles and energy habits. All homes had the same basic size and layout, but some used construction practices typical for the United States and others were designed according to Swiss guidelines for residential construction. The results of the study showed that a Swiss-style low-energy home is not cost effective for the Midwestern United States if energy costs remain low, but it could become attractive if energy rates escalate significantly. It was also recognized that technology by itself will not minimize energy consumption, a result of the second part of the project that explored cultural norms that influence energy use. From the survey of both U.S. and Swiss college students’ lifestyles and energy habits, it was revealed with a high level of confidence that Swiss students are more energy conscious than their U.S. counterparts. Introduction This project evaluated typical U.S. and Swiss residential design to identify construction practices that are most energy efficient. The analysis reviewed current best practices in both countries along with an evaluation of attitudes toward energy use by individuals. In the United States an Energy Star system is being used to model homes. Energy Star is an umbrella of voluntary programs started in 1992, which ran as a joint program since 1996 with the U.S. Environmental Protection Agency (EPA) and the DOE to improve energy efficiency of homes (Banerjee & Solomon, 2003). The Swiss method of building a sustainable home is the Minergie System (Minergie, 2010). Zero Energy Homes (ZEH) have been built in Japan, Sweden, Germany, Norway, Austria, and the United States. Unfortunately, there is no real database to centralize information to globalize the adoption of successful homes worldwide (Charron & Athientitis, 2005). To add to the existing body of knowledge, this project reviewed the importance of moving toward ZEH homes, and the current practices and attitudes of the United States and Switzerland toward energy efficiency. The research modeled six variations of designs that incorporated the Energy Star and Minergie systems.

The goal was to increase the level of dissolved oxygen in a body of water by harnessing solar energy for submerged aeration. The system is composed of six solar panels, a kit of batteries, a linear current booster, pressurized water tank, two pumps, an air compressor, and a float. The design factors for dissolved oxygen (DO) measurements were determined from depth of water, time of the day, location of fountain, and status of fountain (on or off). A Split Plot design was used to investigate the performance of the fountain, based on the changes in levels of DO in the pond. Statistical analysis showed a 120% gain in DO concentration during a 20-day period with significant destratification of the pond.

{"title":"Student Reflective Perceptions of High School Educational Cell Phone Technology Usage","authors":"Beth Humble-Thaden","doi":"10.21061/jots.v37i1.a.2","DOIUrl":"https://doi.org/10.21061/jots.v37i1.a.2","url":null,"abstract":"High school students are prohibited from using cell phones during the school day within most public schools in the United States; the majority of students, however, maintain possession of a personal cell phone within the high school setting. Most administrators and teachers regard cell phone possession and usage as a negative distraction and deterrent to learning rather than as an educational learning tool. This study investigates college freshman students’ reflective perceptions of potential high school utilization of cell phones by students and teachers as educational learning tools. Positive response from surveys suggests there is interest in and potential for educational implementation and use of cell phones as learning tools in schools. Perceptional gender differences were uncovered suggesting further study is necessary before successful implementation can occur. School policy regarding cell phones, within the majority of public schools in the United States, is generally quite prohibitive and requires students to leave their cell phones at home or turn them off and leave them in their lockers during the school day (Obringer & Coffey, 2007). Other schools report changing policy from banning cell phone use to allowing students to use them before or after school (St. Gerard, 2006). As a result of the rapidly occurring technological advances within the cell phone industry, schools have been hard pressed to make and keep current educational policy regarding the use of cell phones (Obringer & Coffey, 2007). Students’ personal and social cell phone use has been well established, but how do high school students reflect on the usage of such phones in an educational setting? Determining student perception toward using the educational technological capabilities of cell phones within a learning environment is a first step. Knowledge of students’ attitudes could possibly lead to, aid in, and influence future decision making regarding the implementation of cell phone use for academic purposes within high school classrooms. Literature Review Administrators and teachers often regard the use of cell phones by students at school as a deterrent to student learning (Johnson & Kritsonis, 2007). Administrators often are concerned about inappropriate use of cell phones in schools and this is the major cause of restricting their use (Obringer & Coffey, 2007; St. Gerard, 2006). Cell phones ringing during a class time present unwanted distractions and, for some students, sending or receiving text messages can lead to cheating (Gilroy, 2003). The existing possibility of posting improper photos on the Internet is also a cause for concern (Obringer & Coffey, 2007). For these reasons, students are not allowed to visibly possess cell phones within most high school classrooms. The challenge faced by many administrators is to effectively balance the needs of the school with the demands of the students and the parents.

Technology can contribute to the education and literacy of university students. If one looks at the larger picture of education and the technological literacy of its students, isn’t this the mission that our profession has as design and technology educators? Expanding design and technology courses to the university general population can be used as numbers to support academic programs while also contributing to a wider student population. This helps us achieve technological literacy for all. Literacy is an important term when one judges the capabilities of people. Connotations of the term literacy reflect on citizen’s abilities to read, write, and use basic mathematics. Countries, where average adult literacy rates are low, are often referred to as developing countries. The levels of literacy are not equal around the globe. Often literacy is associated with a country’s ability to graduate its youth from high school. These rates are often important considerations when one applies for a position at a company in the developing and developed world, e.g., high school graduate, college graduate, master’s degree, etc. The U.S. Workforce Investment Act of 1998 defines literacy as \"an individual's ability to read, write, speak in English, compute and solve problems at levels of proficiency necessary to function on the job, in the family of the individual and in society” (p. 131).","PeriodicalId":142452,"journal":{"name":"The Journal of Technology Studies","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127446350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hartman","doi":"10.21061/jots.v37i1.a.1","DOIUrl":"https://doi.org/10.21061/jots.v37i1.a.1","url":null,"abstract":"Computer-aided design (CAD) software and other product life-cycle management (PLM) tools have become ubiquitous in industry during the past 20 years. Over this time they have continuously evolved, becoming programs with enormous capabilities, but the companies that use them have not evolved their design practices at the same rate. Due to the constant pressure of bringing new products to market, commercial businesses are not able to dedicate the resources necessary to tap into the more advanced capabilities of their design tools that have the potential to significantly reduce both time-to-market and quality of their products. Taking advantage of these advanced capabilities would require little time and out-of-pocket expense, since the companies already own the licenses to the software. This article details the work of a small research team working in conjunction with a major turbine engine manufacturer endeavoring to make better use of the underutilized capabilities of their design software. By using the scripting language built into their CAD package for design automation, knowledge-based engineering applications, and efficient movement of data between design packages, the company was able to significantly reduce design time for turbine design, increase the number of feasible design iterations, increase benefits from relational modeling techniques, and increase the overall quality of their design processes. The design of turbine engines involves creating, modeling, and documenting the development of airfoil geometry for turbine, impeller, and compressor blades. This process is highly iterative due to the circular revisions made between design and analysis groups chasing the optimal airfoil shape and performance. Airfoil blades are a crucial component within a turbine engine, and their design covers many engineering disciplines such as thermodynamics and statics. For both analysis and manufacturing, these airfoils are modeled in a CAD system. However, the complex shapes of airfoils make this difficult. They are typically modeled using b-splines or NURBS, and the development of methods to do this has been ongoing for decades (Corral, Roque, Pastor, & Guillermo, 2004; Korakianitis & Pantazopoulos, 1993)). After revisions are made, geometric data are often reengineered and recreated within the CAD system. This process ranges from hours to days because the current methods of creating the airfoil models in the CAD system are not parametric, (i.e., the geometry is not associated with the engineering definition of the airfoil after the model is created). A turbine engine can contain as many as of 20 different airfoils, so any improvement in the time for one design iteration will have a beneficial effect on the total design process. In addition, additional benefits can be realized depending on whether a turbine, compressor, or fan blade is being designed, as the geometric complexity of each part varies from relatively simple to highly complex.

Printing and related industries constitute one of the major sources of environmental pollution due to heavy energy and resource (materials) use. Therefore, there is a need to adopt resourceful thinking regarding activities in the printing and related industries, so they can contribute to environmental protection by adhering to greener, eco-friendly, and sustainable practices. This article discusses strategies that these industries could adopt, which would put their businesses on sound economic footing as they adhere to sustainable business practices that contribute to and safeguard the environment. Introduction Resourceful thinking about printing and related industries is much more than a focus on hardware and software acquisition in an effort to amass a profit. It is about finding the best tool to get the job done, lowering overhead costs, getting more for less, while eliminating or reducing the negative impact on the environment. As companies realize that wealth is created through technology and by adding value to natural resources, efforts need to be made to ensure that sustainable practices are put in place to protect the environment. Resourceful thinking is about meeting the challenges of creating an environment that fosters scientific discoveries and technological development. It involves the ability to know the demands of the environment, to respond to these demands with technological solutions, to create solutions that link and match the research with the actual demands of the environment, and to structure an environment that moves resourceful thinking through the global economic climate with a view of achieving the solutions needed to address business problems. Some of the strategies that printing and related industries can use to achieve the aforementioned goals include contributing to environmental and economic sustainability; using socially conscious, environmentally friendly products and packaging; establishing safety and efficacy in product design; using renewable and recyclable resources; supporting biodegradability; promoting sustainable harvesting practices; and being accountable to present and future generations of packaging products.

In ENGR1010 at Robert Morris University, freshmen engineering students are introduced to engineering design theory and practice through fun and challenging Rube Goldberg implementations to give them self-confidence early in their education. This article presents a background on Rube Goldberg mechanisms and their use in engineering education. However, the main focus is given to engineering design and microcontrollers in Rube Goldberg mechanisms. The authors worked with a multidisciplinary group of freshmen software and mechanical engineering students to complete an intelligent Rube Goldberg mechanism to assemble cheese sandwiches. The project was accomplished by using a 10-step design process and generating an automated assembly line with Rube Goldberg contraption elements controlled by a microcontroller. The Robot C programming language was employed for programming. The project details, project evaluation, and student responses are also included in this paper. Introducing Engineering Design through an Intelligent Rube Goldberg Implementation Background The Accreditation Board for Engineering and Technology (ABET) and industry demand that engineering students be able to design, work in teams, and be effective communicators (Feland & Fisher, 2002). One freshman engineering course at Robert Morris University entitled, “ENGR1010: Introduction to Engineering” was revised by the authors in order to introduce engineering students to the design process through an implementation of a Rube Goldberg device. A Rube Goldberg process is used to trigger and maintain student motivation for engineering because it provides a mechanism for “learning while having fun.” This design process facilitated teamwork and emphasized communication. According to the Merriam-Webster Online Dictionary (2010) the Rube Goldberg concept is defined as \"accomplishing by complex means what seemingly could be done simply.” This is how Reuben Lucius Goldberg, a Pulitzer Prizewinning artist, portrayed machines and gadgets as excessive for well over 50 years. In addition, he was sometimes skeptical about the technology upon which these devices were based . His cartoons combined simple machines and common household items to create complex and wacky contraptions that accomplished trivial tasks.
