    In graphics our goal is clear; help students learn to visualize so they can ideate with themselves, communicate graphically with others, and communicate according to industrial standards. How we reach these goals is ever changing. In my thirty-four years of teaching graphics the most significant change in the curriculum has been the introduction of 3-D modeling. It has fundamentally changed the way students learn to visualize. But even with this fundamental change my preferred method of teaching graphics has not changed. The only way to learn graphics is to draw and/or model. My teaching philosophy reflects this principle. I call it my “Sink AND Swim” principle of teaching graphics. In a graphics course students do not want to listen to you talk about drawing – they want to do it! I believe students learn and retain graphic principles best when they are allowed to struggle with a problem on their own. After giving students the minimal amount of information to get started, I like to use my three favorite words in teaching “go to work”. This gives me the opportunity to become more of a coach and help students with their struggle. When they begin to sink we can reconvene and talk through the problem a little more. Then the process repeats itself until the task is completed. Ideally I prefer to have all my lecture/lab time entirely in the lab so I can give mini lectures when they are needed

    Pengembangan Blog Budaya Sebagai Sarana Belajar Budaya

    Indonesia is a country that has a diverse culture, ethnicity, language, and rich tourism potentials. However, many people abroad who do not know about the diversity of Indonesian culture. The younger generations were much less aware of even less have sufficient of the richness of the culture of Indonesia. The knowledge about Indonesian culture of Japanese Language Education students Semarang State University, is still inadequate, so they can not be explained to the Japanese society apropiately, not good enough. Therefore students need to be given education by developing blog that contains Indonesian culture which is written in Japanese. The purpose of this study was developing a blog that can be a means of learning the culture. The method used is the Research and Development (R & D), with a step preliminary studies, product development, and product validation testing. Data was collected by questionnaire. Japanese expert validation results towards this blog are considered quite good as a means of studying Indonesian culture with an average score of 2.7 on the aspects of the format, quality, clarity, and clarity of language

    Correctional management : the systemic impact and consequences of truth-in-sentencing legislation

    Recently, a growing number of states have enacted truth-in-sentencing policies which will ensure that certain violent offenders serve at least 85% of their sentence. These policies are designed as a general deterrent to crime by placing an offender behind bars without the chance of parole. Theoretically by increasing the incarceration rate, the effects of incapacitation will grow because fewer offenders will be free to victimize the population at large (Parent, Dunworth, McDonald, & Rhodes, 1997, p.l). Although, truth-in-sentencing policies may sound practical, there is growing debate as to the systemic impact that truth-in-sentencing laws will have on correctional systems. This project examines the systemic impact and consequences associated with truth-in-sentencing legislation. Data was collected on each state\u27s current inmate population, and 5-year prison population forecasts. Previously, studies have only been able to make impact projections based on the assumption that each state will pass truth-in-sentencing laws. This study addresses this limitation by comparing two groups: (1) states that have met the requirements in order to be awarded the FY 1996 Federal Truth-in-Sentencing Grant (see Appendix B); and, (2) states that were not awarded the grant. Additionally, each state adopting truth-in-sentencing was asked to provide the most recent count of inmates serving sentences under truth-in-sentencing laws, as well as to respond to a national mailed survey (see instrument in Appendix D). The results indicated the following: (1) no significant statistical difference between the 5-year projected prison populations of those states that received the FY 96 Federal Truth-in-Sentencing Grant and states that did not; (2) a significant difference within groups projected populations and the number of inmates actually serving sentences under truth-in-sentencing laws; and (3) a variety of consequences associated with truth-in-sentencing legislation. The findings of this study support the hypothesis that truth-in-sentencing legislation may not have an immediate direct systemic impact. Rather, the impact will be felt overtime as a sub-population of violent inmates serving 85% of their sentences will increase, slowing population turnover for this group and effecting prison growth in the future. The results of this study reveal shortcomings and additional questions raising the need for further examination into the systemic impact of truth-insentencing policies

    Aeroelastic Analysis of SUGAR Truss-Braced Wing Wind-Tunnel Model Using FUN3D and a Nonlinear Structural Model

    Considerable attention has been given in recent years to the design of highly flexible aircraft. The results of numerous studies demonstrate the significant performance benefits of strut-braced wing (SBW) and trussbraced wing (TBW) configurations. Critical aspects of the TBW configuration are its larger aspect ratio, wing span and thinner wings. These aspects increase the importance of considering fluid/structure and control system coupling. This paper presents high-fidelity Navier-Stokes simulations of the dynamic response of the flexible Boeing Subsonic Ultra Green Aircraft Research (SUGAR) truss-braced wing wind-tunnel model. The latest version of the SUGAR TBW finite element model (FEM), v.20, is used in the present simulations. Limit cycle oscillations (LCOs) of the TBW wing/strut/nacelle are simulated at angle-of-attack (AoA) values of -1, 0 and +1 degree. The modal data derived from nonlinear static aeroelastic MSC.Nastran solutions are used at AoAs of -1 and +1 degrees. The LCO amplitude is observed to be dependent on AoA. LCO amplitudes at -1 degree are larger than those at +1 degree. The LCO amplitude at zero degrees is larger than either -1 or +1 degrees. These results correlate well with both wind-tunnel data and the behavior observed in previous studies using linear aerodynamics. The LCO onset at zero degrees AoA has also been computed using unloaded v.20 FEM modes. While the v.20 model increases the dynamic pressure at which LCO onset is observed, it is found that the LCO onset at and above Mach 0.82 is much different than that produced by an earlier version of the FEM, v. 19

    Combustion-derived nanoparticles: mechanisms of pulmonary toxicity

    Get PDF
    1. The general term ‘nanoparticle’ (NP) is used to define any particle less than 100 nm in at least one dimension and NPs are generally classified as natural, anthropogenic or engineered in origin. Anthropogenic, also referred to as ‘ultrafine’ particles (UFPs), are predominately combustion derived and are characterized by having an equivalent spherical diameter less than 100 nm. 2. These particles, considered to be ‘combustion-derived nanoparticles’ (CDNPs), are of toxicological interest given their nanosized dimensions, with properties not displayed by their macroscopic counterparts. 3. The pulmonary deposition efficiency of inhaled UFPs, along with their large surface areas and bound transition metals, is considered important in driving the emerging health effects linked to respiratory toxicity. 4. The toxicology of CDNPs is currently used to predict the health outcomes in humans following exposure to manufactured NPs. Their similar physicochemistry would suggest similar adverse health effects (i.e. pulmonary (and perhaps cardiac) toxicity). As such, it is essential to fully understand CDNP nanotoxicology in order to minimize occupational and environmental exposure. Key words: carbon black, combustion-derived particles, diesel exhaust, fly ash, nanoparticles, pulmonary toxicity

    Outdoor, Indoor, and Personal Exposure to VOCs in Children

    We measured volatile organic compound (VOC) exposures in multiple locations for a diverse population of children who attended two inner-city schools in Minneapolis, Minnesota. Fifteen common VOCs were measured at four locations: outdoors (O), indoors at school (S), indoors at home (H), and in personal samples (P). Concentrations of most VOCs followed the general pattern O ≈ S < P ≤ H across the measured microenvironments. The S and O environments had the smallest and H the largest influence on personal exposure to most compounds. A time-weighted model of P exposure using all measured microenvironments and time–activity data provided little additional explanatory power beyond that provided by using the H measurement alone. Although H and P concentrations of most VOCs measured in this study were similar to or lower than levels measured in recent personal monitoring studies of adults and children in the United States, p-dichlorobenzene was the notable exception to this pattern, with upper-bound exposures more than 100 times greater than those found in other studies of children. Median and upper-bound H and P exposures were well above health benchmarks for several compounds, so outdoor measurements likely underestimate long-term health risks from children’s exposure to these compounds
