We present a novel micro-mixer/reactor based on arrays of spatially impinging micro-jets. Using the plumes from two opposite micro-nozzles, interfacial contact in mixing chamber was significantly boosted. This effect has effectively increased efficiency. The presented this paper very simple structure and fabricated using technology UV lithography SU-8 resist. experimental results prototype mixers have proved high efficiency with pressure drop about 200 Pa. can be easily integrated other...
To reduce the cost of prototype and physical tests, CAE analysis has been widely used to evaluate vehicle performance during product development process. Combining optimisation approach, design process can be implemented more efficiently at affordable cost. Reliability-based (RBDO) formulation considers variations input variables, such as component gauges material properties. This paper is on application reliability-based automotive structures.

Abstract This research presents a new application of topology optimization. Patterns for spot weld location and adhesive distribution when joining body panels are determined by using the optimization method. The density method which parameterizes each finite element is employed sequential linear programming used solving problem. In this study, B-Pillar to Rail Joint exemplifies design methodology. results show that patterns optimal can be obtained maximum stiffness with mass constraints.

In response to the call for agent-based solutions that leverage ever-increasing capabilities of deep models' ecosystem, we introduce Hive -- a comprehensive solution selecting appropriate models and subsequently planning set atomic actions satisfy end-users' instructions. operates over sets and, upon receiving natural language instructions (i.e. user queries), schedules executes explainable plans actions. These can involve one or more available achieve overall task, while respecting...

Abstract This work deals with the problem of computing optimum topology structures subject to a force frequency spectrum. The analysis is done in domain and computed using simplified density approach. Optimization formulation as well sensitivity are discussed. An example showing capabilities computational implementation presented.
Abstract In many engineering structures, failure occurs either at the connection itself or in component point of attachment connection. To extend service life structure it is important to ensure that loads borne by connections are distributed as uniformly possible. This would also minimize possibility localized high stress regions within component. this work a topology optimization based approach has been developed incorporate fastener load constraints into problem formulated for optimal...
The connected pipe thread will be loosed under the pressure impact and vibration effects. Based on analysis of sealing mechanism thread, essence loosening is caused by fretting damage fatigue. following three methods are used to reduce damage: processing requirements internal external screw tooth type size improved;the deformations which made a screwing torque material itself fill gap in each part after screwed together;plasticity filler put between thread.
