This paper illustrates an effective application of rapid prototyping (RP) to produce a high definition polymer model of a satellite structure prior to final machining of the aluminum panels. The benefits when using this type of model in the design and assembly stages of satellite fabrication make clear that RP can and should play an important role in the design and fabrication of small satellite structures.

Selective laser sintering was utilized to produce a full‐scale model of a novel modular small satellite structure. This model was then used as a tool for quality control, fit check, assembly process verification, mock‐up, and as a model for manufacturing tooling design.

This case study illustrates that the use of RP to create a model early in the design cycle is beneficial from a cost and time perspective even when applied to a product which will be produced in a quantity of one. In addition, the merits of RP mesh well with modular designs and for applications where assembly and test tooling is required to validate the quality of a product.

This paper illustrates an effective use of RP in the satellite fabrication industry. The benefits described are generally applicable to other complex systems which need design validation early in the design cycle.

There are few examples of the effective application of RP to produce models, but not the final product, of a complex structure in the satellite and other industries where small lot production occurs.

Bayesian additive regression trees (BART) is a fully Bayesian approach to modeling with ensembles of trees. BART can uncover complex regression functions with high-dimensional regressors in a fairly automatic way and provide Bayesian quantification of the uncertainty through the posterior. However, BART assumes independent and identical distributed (i.i.d) normal errors. This strong parametric assumption can lead to misleading inference and uncertainty quantification. In this chapter we use the classic Dirichlet process mixture (DPM) mechanism to nonparametrically model the error distribution. A key strength of BART is that default prior settings work reasonably well in a variety of problems. The challenge in extending BART is to choose the parameters of the DPM so that the strengths of the standard BART approach is not lost when the errors are close to normal, but the DPM has the ability to adapt to non-normal errors.

The purpose of this paper is to explore the effect of different parameter configurations of oscillation amplitude, welding speed, and normal force at 478 K (400°F) on the linear welding density of stainless steel 316L annealed utrasonically consolidated (UC) samples, and present an optimum parameter set based upon maximum linear welding density criteria.

The paper describes the application of analysis of variance to different experimental designs in order to compare factor effects and obtain the optimum linear welding density parameter set for the ultrasonic consolidation of stainless steel 316L annealed samples.

This work includes experimental results at assessing the explained variation due to factor effects on linear welding density, the statistical significance of these factors, and the combination of UC process parameters that maximizes linear welding density in stainless steel 316L annealed samples.

The paper presents results obtained with a specific UC system, a standard sample configuration, and relatively constant frictional conditions.

This work is a first step towards a reproducible UC of stainless steel 316L foils with high linear welding density.

There has been little thought given in science to the impact of direct brain‐machine interfacing upon the future development of human consciousness. Even less thought has been given to the possibilities for both optimizing and thwarting development in the cyborg child. A neurocognitive model of the evolution of cyborg consciousness is summarized, and from this model grounded speculations are offered pertaining to the future development of the higher cognitive functions in the cyborg child. It will be shown that cybernetic implants are “multistable”; that is, the artificial intelligence (AI) component of the cyborg brain‐machine linkage may function to condition development along ideological lines (the brain conditioned by the “ideological chip”), or may operate to open up neurocognitive development to new and heretofore unrealized limits (the brain’s development optimized by the “guru programme”). Development of the cyborg child may be conditioned in the interests of ideological concerns, or may lead to a consciousness that easily transcends all forms of ideology. Application of the guru programme may foster the emergence of new levels of cognitive complexity and information processing (à la Piagetian and neo‐Piagetian theory) that in turn allows new strategies of adaptation previously beyond human comprehension. The ethical and regulatory problems raised by cyborg technologies are addressed.

As the bell rang, sounding the beginning of the school day, Ji-Sook (Elizabeth) entered the classroom, her pink tweed coat and mittens still frosty from the snow outside. This was Ji-Sook's second year of school in Canada and her first year at Streamside School. She really liked it here and loved her teacher, Ms. Song Lee. Ms. Lee was always sharing stories with the class about her experiences growing up in another country as well as her arrival to Canada and growing up in small towns where Ms. Lee was often the only Chinese person in her school. Listening to Ms. Lee's stories helped Ji-Sook think about Korea and her family there.Removing her coat, Ji-Sook moved quickly to hang it up, her dark curly bobbed hair bouncing as she skipped. Her newly permed hair felt different, but she liked the way it looked. Today Ji-Sook was wearing a favourite outfit, a knitted sweater with a matching plaid skirt. After hanging up her coat, Ji-Sook turned to face the class and noticed that along with her teacher, Ms. Lee, was Ms. Mitton and Ms. Simmee. Ji-Sook was surprised to see Ms. Mitton and Ms. Simmee at school on a Tuesday morning for they usually came in the afternoon. She greeted them happily and took another close look around the room for Ms. Jean. Ji-Sook asked Ms. Mitton where Ms. Jean was; Ms. Mitton smiled and reminded Ji-Sook that Ms. Jean would be coming Wednesday afternoon. Ji-Sook remembered to ask if Ms. Mitton would read with her during shared reading time.Ji-Sook knew it was going to be a very special day. Yesterday afternoon Ms. Lee had reminded the children that in the morning they were to begin a wonderful art project and create their own Starry Night paintings. Quickly Ji-Sook removed the book about Van Gogh, which discussed his Starry Night painting, from her backpack and, before everyone was seated, showed Ms. Lee and Ms. Simmee her book from home. The night before, she and her mother had spent time reading the book aloud. Ji-Sook felt it was much easier to read aloud in Korean than in English. Today's art lesson was out of the ordinary for she loved being able to bring things from home that fit with what they were learning in the classroom. And today was very special.Before going to her desk, Ji-Sook retrieved the poetry book that had a picture of a boy peering over the end of a sidewalk,¹ Ji-Sook hurried to her desk and sat down and waited for Ms. Mitton to join her for reading. Seated with three of her classmates at a table composed of 4 desks, she smiled at Nathan, Grace, and Dana. There was so much to be excited about as she knew that after school today there were parent teacher interviews. Ji-Sook knew her mother was not working at the deli shop and was going to come to the interviews with their neighbour who would translate for her. Ji-Sook so loved it when her mother came to school. Once Ms. Mitton arrived, she and Ji-Sook spent a few minutes reading aloud together before Ms. Mitton went to join Ji-Sook's friend, Hailey, who had also asked Ms. Mitton to read with her. Ji-Sook continued to read and look at the drawings in this wonderful book.Adjusting her headset and microphone, Ms. Lee asked Ella, the class's ‘star-of-the-week’, to tap on the desks of each group to indicate that they were to come to the sharing area. Ji-Sook waited excitedly for Ella to tap her group's desks and then she hurriedly joined Grace, Nathan, Dana, and the rest of her classmates on the foam mats by the picture window. Ms. Lee began the art lesson by showing examples of Starry Night paintings completed by the students she had taught last year. Ms. Lee then shared the rubric with which Ji-Sook and her friends could assess their paintings. Ji-Sook knew that Ms. Lee worked with Mrs. D, the other Grade 3 teacher, and that students in both classes would be making the paintings. Once Ms. Lee finished explaining the steps of their art lesson, she asked Ji-Sook if she would like to come and share the book she brought from home.Sitting at the front of the class in Ms. Lee's chair and wearing her microphone, Ji-Sook read aloud from the book. The book was in Korean and Ji-Sook scanned each page quickly before explaining to the class bits and pieces about Van Gogh's life. Ji-Sook, reading from her book, explained that Van Gogh cut off his ear because he couldn’t draw his own portrait properly. Ms. Lee later returned to this detail and asked about how this piece of information in Ji-Sook's book was different from what they had previously read about the artist. The children remembered that Van Gogh cut off his ear for a woman he loved and had offered his ear as a gift to her. Ms. Lee asked the class to think about these two different pieces of information. Following this question Ms. Lee asked what the children might do to ensure the information they found was accurate. Logan suggested that reading many sources would help.Ms. Lee then drew the children's attention to Ji-Sook and said that as Ji-Sook read she was doing two things at the same time. She asked the class what they thought she was doing. Mya suggested Ji-Sook was reading and then talking. Picking up on Mya's point, Ms. Lee emphasized that Ji-Sook was reading in Korean first and then translating what she read into English. Ms. Lee asked Ji-Sook if she would like to read aloud in Korean. Ji-Sook momentarily hesitated but responded with a smile when her classmates encouraged her. Ji-Sook read one page aloud. She read quickly and the rhythm of how she read aloud in Korean sounded very different from her reading skills in English.Paper and crayons were distributed. Ji-Sook, Grace, Nathan, and Dana were quiet as they began their Starry Night paintings. Looking over the rubric that Ms. Lee had explained, Ji-Sook understood the first step today was to plan the sky and landscape of her painting. She knew the sky was to be about 2/3 of the paper and that everything she drew was to be in small dashes. It was important for the sky of her painting to look like it was moving. Ji-Sook was aware of Ms. Lee moving about the classroom, helping her classmates check, whether or not, the sky in their paintings was approximately the right size. As everyone worked, Ji-Sook heard Ms. Lee remind the class to press hard with their crayons so that the paint would have something to cling to as it dried. Taking Ms. Lee's advice seriously, Ji-Sook pressed firmly each time her crayons touched the paper, and soon her right arm grew tired. Ji-Sook now had a better idea about what Ms. Lee meant by this art project taking a long time to complete. (Interim research text based on field notes,² November 21, 2006)

The purpose of this paper is to explore how flourishing is achieved among sport employees working at intercollegiate sport organizations in the USA. To do so, a model is constructed that examines the impact of pride and path-goal leadership on job engagement and then flourishing. The model is grounded in the Human Resource Development (HRD) paradigm to extend the literature on positive performance outcomes in sport organizations.

Quantitative methods were used to analyze the data. Altogether, 282 useable surveys were completed by sport employees working in intercollegiate athletics departments. The hypotheses were examined with structural equation modeling to provide robust calculations of the relationships within the model.

The findings of this study demonstrated that both path-goal leadership and pride enabled job engagement, which in turn supported flourishing among intercollegiate athletics employees (e.g. equipment, marketing or facility/event positions). Job engagement is positioned as an important variable as it linked path-goal leadership and pride with flourishing.

This study examined mechanisms (i.e. path-goal leadership, pride) to enhance intercollegiate athletics employees' personal resources (i.e. job engagement, flourishing) through the HRD paradigm. The HRD framework posits that improved employee functioning leads to a superior organizational performance and has yet to be assessed within intercollegiate athletics. The findings add to the HRD literature by focusing on employees' workplace experiences and generating pathways to improved job engagement and the subsequent influence on intercollegiate athletics employees' ability to flourish, which is also understudied.

The increasing interest in engineering structures made from multiple materials has led to corresponding interest in technologies, which can fabricate multi‐material parts. The purpose of this paper is to further explore of the multi‐material fabrication capabilities of ultrasonic consolidation (UC).

Various combinations of materials including titanium, silver, tantalum, aluminum, molybdenum, stainless steel, nickel, copper, and MetPreg^® were ultrasonically consolidated. Some of the materials were found to be effective as an intermediate layer between difficult to join materials. Elemental boron particles were added in situ between selected materials to modify the bonding characteristics. Microstructures of deposits were studied to evaluate bond quality.

Results show evidence of good bonding between many combinations of materials, thus illustrating increasing potential for multi‐material fabrication using UC.

Multi‐material fabrication capabilities using UC and other additive manufacturing processes is a critical step towards the realization of engineering designs which make use of functional material combinations and optimization.

Recently, a number of research projects have been focused on an emerging additive manufacturing process, termed ultrasonic consolidation (UC). The purpose of this paper is to present an analytical energy model aimed at investigating the effects of process parameters on bond formation in UC.

In the model, two factors are defined, energy input to the workpiece within a single cycle of ultrasonic vibration (E₀) and total energy input to the workpiece (E_t), to evaluate to the magnitude of transmitted energy into the workpiece during UC.

It is found that linear weld density, E₀ and E_t are affected by process parameters in similar manners.

The current model is developed based on several simplifying assumptions, and energy dissipation and bond degradation during UC are not considered in the model.

The current model gives a useful understanding of the effects of process parameter on the bond formation in UC from an energy point of view.

Rapid prototyping (RP) techniques are being increasingly used to manufacture injection molding and die casting core and cavity sets, known as tools, and for other tooling‐related parts, such as EDM electrodes. This paper presents a STL‐based finish machining technique for tools and parts made using RP techniques in order to achieve the tight tolerance and surface finish requirements necessary for tooling applications. Rotate, scale, translate and offset algorithms are used to pre‐process the 3D model prior to its manufacture. A machining strategy of adaptive raster milling of the surface, plus hole drilling and sharp edge contour machining, is developed to finish the parts and tools after fabrication using RP. Finally, a benchmark part was designed and fabricated using the above‐mentioned strategies and the results show the effectiveness of the developed software.
