The introduction of high speed computers with excellent graphic rendering capabilities and software that takes advantage of those capabilities have precipitated a change in the philosophy of teaching introductory courses in graphics. studies of introductory computergraphics courses have indicated that algorithms, such as line and circle drawing and polygon fills, and the study of data structures to support graphics are common topics taught in introductory courses. A cursory review of available software tools for teaching computergraphics topics indicates that there is a lack of web-based visualizations of commonly taught computergraphics algorithms. The purpose of this paper is to describe a web-based tutorial that has been used to supplement an introductory computergraphics course.

Cloud Gaming is emerging as a viable alternative to traditional stand-alone and online computer games. The current trend is to design efficient remote-rendering models for cloud gaming that allow video packets of game scenes to be sent across, from servers to clients, for an optimal game experience. This approach, however, still raises concerns in terms of network bandwidth and costs associated, becoming bottlenecks for game developers and users, particularly under scarce bandwidth availability. In this paper, we propose an architecture for computer gaming that leverages cloud advantages for gaming in the absence of necessary bandwidth to support remote rendering. Implementation of the proposed model through Amazon Web Services (AWS) using a prototype game and evaluation through several studies has revealed that only 1KBps data per player is transferred between cloud and players. Through these results, the paper presents arguments for more careful planning and need for further documentation in order to design games, choosing the correct resources as part of the architecture.

Personal computer (PC)-based systems have made some inroads into the professional video production arena in recent years, sewing primarily as nonlinear editing and graphics workstations, However PCs have thus far failed to replace single-function legacy equipment, instead they function with existing products such as video switchers, digital video effects systems, character generators, and audio mixers, The true benefits of the PC in video production will not be realized until the entire pr odncfion process is integrated into one system. This step will use the economics of the general purpose PC to dramatically decrease the cost of video production, while making the entire process easier to learn and practice, integration will also further expand the toolset available to producers by providing a myriad of tools from hundreds of developers, all for one platform. This paper examines the reasons why PC-based systems have failed thus far to make this step and examines some solutions to these problems.

How can a company establish a baseline measurement of its safety culture against which to gauge improvement? The Site Safety Index™ (SSI) quantifies in part (on a scale of 0 - 4) the degree to which a company's end-user practices support the attainment and retention of an appropriate safety culture for operations and maintenance. Further, the SSI can be used to appropriately adjust parameters that directly impact measures of safety such as probability of failure on demand (PFDavg). Thus, the impacts of safety culture can be further quantified and the effects of changes to safety culture can be assessed.

In this work we address the problem of landmark recognition. We extend PlaNet, a model based on deep neural networks that approaches the problem of landmark recognition as a classification problem and performs the recognition of places around the world. We propose an extension of the PlaNet technique in which we use a voting scheme to perform the classification, dividing the image into previously defined regions and inferring the landmark based on these regions. The prediction of the model depends not only on the information of the features learned by the deep convolutional neural network architecture during training, but also uses local information from each region in the image for which the classification is made. To validate our proposal, we performed the training of the original PlaNet model and our variation using a database built with images from Flickr, and evaluated the models in the Paris and Oxford Buildings datasets. It was possible to notice that the addition of image division and voting structure improves the accuracy result of the model by 5-11 percentage points on average, reducing the level of ambiguity found during the inference of the model.

In early spring 2002 the technology support staff at Bucknell University set out on a staff-driven reorganization and work redesign. In addition to describing the processes we used to begin, plan, develop and implement our reorganization, we will focus on the characteristics of our unique collaborative work environment and organizational values that enable us to undertake projects such as this. Many believe that reorganizations have to happen from the top down. Our reorganization took place from the bottom up and it has made all the difference. Ownership, trust, empowerment, collaboration, service, leadership at all levels of the organization, and creativity - these words sum up our process and our outcomes. It has been an amazing adventure!

2014 We present a new approach for combining k-d trees and graphics processing units for nearest neighbor search. It is well known that a direct combination of these tools leads to a non- satisfying performance due to conditional computations and suboptimal memory accesses. To alleviate these problems, we propose a variant of the classical k-d tree data structure, called buffer k-d tree, which can be used to reorganize the search. Our experiments show that we can take advantage of both the hierarchical subdivision induced by k-d trees and the huge computational resources provided by today's many-core devices. We demonstrate the potential of our approach in astronomy, where hundreds of million nearest neighbor queries have to be processed.

In image morphing applications, deformation is not desired since it looks strange. To avoid deformation, the angles must be locally preserved. By deforming features, we can obtain funny-looking images, however, the shapes of the features will not look preserved if angles are not preserved. The angle-preserving operations are called conformal maps and locally they expect to be reduced into a concatenation of rotation, uniform scaling, and translation operations. This conceptual framework appears to give us a straightforward framework to construct general conformal maps. We can simply define desired rotation, uniform scaling, and translation in some select points and interpolate them by preserving their conformal property. Unfortunately, this does not work if these local operations are defined by using 3x3 matrices. Our approach is based on the well-known conformal property of maps in complex domains. Namely, any map in a complex domain is angle-preserving. Based on this well-known property of complex numbers, we show that if the local operations are defined as affine operations on complex numbers then any interpolation on complex numbers will give us conformal mapping of the whole domain. This is very useful since we can make extreme exaggeration of some local features and the resulting maps are still guaranteed to be conformal. Using this property, we have implemented an extended and conformal version of feature-based image metamorphosis.
