With the rapid advance of the intelligent transportation system (ITS), the vehicular networks have a potential importance. Currently, these networks are suffering a major challenge due to the widespread demand for services associated with shipping safer, more efficient, cheaper, infotainment, and more sustainable. Researchers and companies are working to generate novel applications. Intelligent Transportation...
Many structural elements are exposed to conditions of load that are difficult to consider during the design stage, such as environment uncertainties, random impacts, overloads and inherent material idealization amongst others, hence, miss-estimating its life-time cycle. One way to test those designs is to construct a representative full-scale specimen and test it under the most critical load conditions...
3D image rendering for virtual reality HMDs is typically generated based on a set of parameters taken from the manufacturer-supplied specifications and an idealised perspective model. But actual displays may vary in build features that alter spatial perception. Moreover, the eye focusing effort is often ignored. The resulting visual discomfort and incorrect geometry perception has discouraged use...
Facility layout has an important impact on the performance of a manufacturing organization. The problem concerns the modeling, planning and design determination of the human activities and the physical resources. The manufacturing activities require an interaction between several management departments of the organization such as procurement, storage and maintenance; thus the necessity of the consideration...
Driving cycles currently available cannot be used for the eco-design of vehicles power trains because those cycles do not describe local driving patterns. The main difficulty in obtaining a representative driving cycle is the lack of a repeatable and reproducible methodology to ensure that the resulting cycle is representative of local conditions. We developed a methodology to address this need, based...
The pharmaceutical manufacturing field is one of the most challenging fields due to stringent regulations, global harmonization and tough competition. It has been realized that quality, safety and efficacy of pharmaceutical drug products are key elements for success in market. However, improving quality requires better understanding of the product and process critical quality attributes (CQAs). The...
This paper presents the remote control of a mobile robot via the Internet. The delay time is one of the biggest obstacles for many real-time applications, especially for Internet-based control systems. This article presents three architectures to control a robot in an Internet network without guaranteed quality of service. These architectures allow us to control the robot movements accurately and...
This paper deals with the application of interactive engineering through an electroencephalogram (EEG) to detect the level of distraction or concentration of drivers of automotive vehicles. In particular, for the case of alerts, signals or outputs emitted by an advanced driver assistance systems (ADAS) in the intelligent transportation systems context. To do that and based on the state-of-the-art,...
The hardware in the loop (HIL) platforms constitute an accelerated engineering design medium that subsequently reduces the risk of failure in the implementation process. This fact is enhanced when the designer is faced with extremely complex tasks and when design errors can lead to destructive and costly testing. The design of complex algorithms such as non-linear controllers applied to electronic...
In this paper, finite element analyses were carried out on thermal stresses at the tubesheet of floating-head or U-tube heat exchangers with square layout of tubes based on parametric finite element models of the tubesheet established with ANSYS parametric design language (APDL). It is found that for thick tubesheet with large temperature difference between two the sides, the maximum thermal stress...
The complexity of the physical or technological systems to be developed or studied led to employing numerical methods based on the principle of an approach as possible nominal solution, but these require large computations requiring efficient computers. The computer code ANSYS also allows the determination and the visualization of the structural deformations due to the contact of slipping between...
Game theory is a branch of mathematics that deals with the analysis of competitive situations in which the outcome of the participants critically depends on the actions of other participants. Popular fields of application include economics and finance, business, military, politics and biology, and more recently it has been applied to several aspects related to networks and Intelligent Transportation...
The global product development is done by global teams being physical, Virtual Teams or blend in-between. Millennials are the new engineers and designers that conform Virtual Teams. Virtual Teams members interact through various electronic media. Even the social collaboration platforms such as Facebook, Skype, Whatsapp, etc are software tools or apps designed to enable social interaction of a group...
The progress of problem solving techniques in industry must gain concentration and commitment otherwise innovation results obtained by new technologies and recent researches will produce weak output. Moreover due to rapid changes in product, material, tool and process, advances in Problem Solving can be focused on transferring knowledge for troublesome assemblage by thinking in productivity in order...
The objective of this paper is to formalize and enrich the relation between user experience and interaction. Both a State of the Art and an Empirical Study are presented along this paper. It results in a theoretical model of design information that formalizes and highlights key principles of the interdependency between user experience and interaction in early design. The research is situated within...
What does it make some sports such as off-road motorcycle to be perceived as non-environmentally-friendly? Are the activities themselves or the actual and/or traditional way of their fulfillment? How is it possible to make them more environmentally sustainable without giving up the fun? This paper aims to give an answer to these questions, analyzing the case of off-road motorcycling. It is clear that...
The distribution characteristics of cutting heat in hardened steel mold surface the milling process have a significant impact on its surface integrity. To meet the structural styles of convex surface, concave surface or both co-exist surface functional required in actual machining, die with characteristic of sinusoidal surface is established. Through the milling experiment, the cutting temperature...
This paper proposes a methodology for enabling a 3 axes Mill CNC machine to work in a synchronized operation with 5 axes. Different alternatives for communicating the fifth axis were analyzed, as using a TRT-160 with a microcontroller and an analog multiplexer. Another option could be done by using a CNC via serial bus and a Microcontroller digital I/O ports, passing the code through a converter code,...
In this study, the finite element method was used to produce a Y-block valve with a weight of 2042 kg. To compare the new process with the traditional production process for this workpiece, both were simulated using finite element ABAQUS software. The viscoplastic properties of material were measured using a thermomechanical simulator (plasto-dilatometer),and then the two models were simulated in...
Over the last years, good strategies for efficient manufacturing were considered increasing the volume of production and reducing the time and costs. Emerging design strategies as the Design for Environment and life cycle assessment, the Design for Sustainability, the Design for Disassembly moved the focus to conceive a product by taking care of all the effect that its use can cause to the economy,...
