Energy harvesting (EH) technologies could lead to self-sustaining wireless sensor networks (WSNs) which are set be a key technology in Industry 4.0. There numerous methods for small-scale EH but these differ greatly their environmental applicability, energy conversion characteristics, and physical form makes choosing suitable method particular WSN application challenging due the specific application-dependency. Furthermore, choice of is intrinsically linked non-trivial decisions on storage...

In a number of additive layer manufacturing processes, particularly for metals, additional support structure is required during the build process to act as scaffolding overhanging features and dissipate heat. Such structures use valuable raw materials their removal adds post processing time. The objective this study was investigate whether simple, single optimisation technique could be used find best orientation part, that would minimise volume needed build. Not only reducing waste but...

The choice of location the evaluation points is important in response surface generation, especially when evaluations are expensive. Space-filling designs can be used to specify so that as much design space sampled possible with minimum number evaluations. One popular technique optimal Latin hypercube experiments. However, its generation non-trivial, time consuming and – but for simplest problems infeasible carry out by enumeration. Therefore, solving this problem requires an optimization...

An automated fully stressed design approach based on the Xie and Steven algorithm is presented. With this a obtained by gradual removal of low material. By applying evolutionary procedure layout or topology structure can be found from an initial block A integrated, interactive program presented which incorporates automatic mesh generation, finite element analysis algorithm. The feasibility demonstrated using several examples.

This paper explores some design parameters of an interior permanent magnet synchronous motor that contribute to enhancing performance. Various geometry such as dimension, machine diameter, stator teeth height, and number poles are analyzed compare overall torque, power, torque ripples in order select the best their ranges. Pyleecan, open-source software, is used optimize for electric vehicle applications. Following optimization with Non-dominated Sorting Genetic Algorithm (NSGA-II), two...

Abstract Gestures are a common way people communicate. Gesture-based teleoperation control systems tend to be simple operate and suitable for most people’s daily use. This paper employed LeapMotion sensor develop mobile robot system based on gesture recognition, which mainly established connections through client/server structure. The principles of recognition in the were studied relevant self-investigated algorithms—GestureMoRo, association between gestures robots designed. Moreover, order...

This paper presents an approach of how warpage (i.e. part deflection) and injection pressure intricate geometry could be minimised by selecting optimal thermoplastic material gate location (through which the molten plastic flows into cavity). The numerical analyses for mould filling considered four locations along with a PP (polypropylene), PS (polystyrene) fibre-filled (each had different shrinkage characteristics, mechanical property viscosity). Results cavity simulations indicated that...

In this paper, the application of Augmented Reality (AR) for control and adjustment robots has been developed, with aim making interaction easier more accurate from a remote location. A LeapMotion sensor based controller investigated to track movement operator hands. The data allows gestures position hand palm’s central point be detected tracked. Kinect V2 camera is able measure corresponding motion velocities in x, y, z directions after our post-processing algorithm fulfilled. Unreal Engine...

In this work a two step approach to efficiently carrying out hyper parameter optimisation, required for building kriging and gradient enhanced metamodels, is presented. The suggested makes use of an initial line search along the hyper-diagonal design space in order find suitable starting point subsequent based optimisation algorithm. During upper bound constraint imposed on condition number correlation matrix keep it from being ill conditioned. Partial derivatives both condensed log...

Magnetic control systems of micro-robots have recently blossomed as one the most thrilling areas in field medical treatment. For sake learning how to apply relevant technologies services, we systematically review pioneering works published past and divide magnetic into three categories: stationary electromagnet systems, permanent magnet mobile systems. Based on this, ulteriorly analyze illustrate their respective strengths weaknesses. Furthermore, aiming at surmounting instability system,...

Residual stress is a major problem for most metal-based laser powder bed fusion (L-PBF) components. can be reduced by appropriate build planning and post-process heat treatments; however, it not always avoidable lead to failures due distortion cracking. Accurate measurement of residual levels difficult high equipment set-up costs long processing times. This paper introduces simple but novel method measuring stresses via three-pronged cantilever component, the three-prong (TPM). The allows...
