Discusses ABB Combustion Division's design and construction of an overfire air system for biomass-fired power boilers at a number of paper mills, which increased capacity by 50% while reducing particulate emissions by 40%. Use of the FLUENT computation fluid dynamics (CFD) software from Fluent Inc.; Fuel used in the mills; Steps in the simulation process.

The article discusses the trends in digital product development. It highlights the developments in the engineering industry from the use of paper engineering drawing to three-dimensional (3-D) wire-frames. It cites that these changes in the engineering industry have been brought about by advances in information technology (IT). Moreover, it explores the three categories when examining trends in digital product development, which would be helpful in predicting the future of mechanical engineering. These categories include technology modeling, geometry modeling and process modeling.

The article reports on the white paper "Predicting Critical Metrics for Wireless RF Links" from National Instruments Corp. which focuses on the use of radio frequency (RF) system simulation software. It mentions that the white paper explains the benefits of Visual System Simulator (VSS) software to define components such as amplifiers and mixers. It also cites the examples presented in the white paper in which the capabilities of system design software were demonstrated.

The article announces the presentation by the National Training and Simulation Association of their 2017 Governor’s Award for Lifetime Achievement in Modeling and Simulation to senior director at Northrop Grumman Mission Systems John D. Illgen, the presentation of the I/ITSEC Lifetime Achievement Award to NTSA head staff member Barbara McDaniel, and the selection of "Human Systems and Instructional System Design for a Simulator of a Robotic Surgical System" as I/ITSEC 2017 Best Paper.

Information about several papers discusssed at the Automotive and Engine Testing Expo held in Sarasota, Florida in October 2015 is presented. Topics include automotive and engineering equipment and presentation by semiconductor industry veteran Gene Lukianov on mathematical analysis and simulations. The expo featured seveal exhibitors including Yokogawa, Newton's 4th, and Signal.X.

The article highlights the white paper "Using Simulation To Optimize Safety, Performance and Cost Savings When Integrating an Antenna Onto A Platform," which discussed computer simulation tools used to model the performance of antennas under moving conditions. Topics discussed include antenna simulations performed at the U.S. Army Communications-Electronics Research, Development, and Engineering Center (CERDEC) using the XFdtd software and an in-house ray tracing tool.

The article presents information on transaction-level models (TLM). TLM verification methodologies are propagating down from power users, such as large systems houses and integrated device manufacturers, to the broader design community. Standards organizations such as the Open Core Protocol International Partnership (OCP-IP) are helping to make TLM methodologies easier to use and ever more powerful. OCP-IP has released Version 2.1.1 of its TLM Channel specification, as well as a comprehensive methodology white paper that describes the use of TLMs for architectural modeling. Version 2.1.1 improves model interoperability by unifying the way time is modeled in transaction level 1(TLI). Some TLI application-programming-interface functions also have been redesigned to ensure interoperability, and new timing interfaces have been added to the TLI channel for automating the setting of module timing parameters. The new methodology package also aligns the Open SystemC Initiative's TLM methodology with OCP-IP's.

Presents the results of a study on the reason behind the manner of the flight of thin flat objects. Impact of air flow changes on the prediction of the falling trajectory; Background on the use of computer simulation in the study; Application of the falling-paper effect in the dispersal of seeds from trees.

The article presents information related to several events to be held related to computer animation. Under the SIGGRAPH 2004 Conference, different categories are divided. Under the category of Courses, which will be held from August 8-11, 2004, are tutorials, half-day sessions, and full-day courses teach beginning, intermediate, and advanced topics in digital art and science, including interaction design, perception, computing hardware, display systems, wireless applications, gaming, animation, and modeling. SIGGRAPH 2004 Papers, which will be discussed from August 9-12, set the standard in the field, stimulate future trends, and explore challenging issues in related fields: human-computer interaction, computer-aided design, computer vision, robotics, visualization, web graphics, and computer games, among others. Sketches, to be discussed from August 8-12, emphasize novel and interdisciplinary applications of computer graphics and interactive techniques, including provocative speculation, academic research, industrial development, practical tools, and behind-the-scenes explanations of commercial and artistic works.

The article describes the functions of Spice simulators. Types of tools of Spice simulators for voltage and current sources are independent, dependent, and behavioral. Behavioral sources are said to be the least-used sources but the most powerful. These sources can implement mathematical functions that correspond to those available on scientific calculators. Behavioral sources can also be used to test the mathematical viability of a design before the simulation of the circuit.
