Purpose – Main purpose is to present methodology which allows efficient hand gesture recognition using low-budget, 5-sensor data glove. To allow widespread use of low-budget gloves in engineering virtual reality (VR) applications, dictionaries must be enhanced with more ergonomic and symbolically meaningful gestures, while providing high rates when used by different seen unseen users. Design/methodology/approach The simple boundary-value was replaced a probabilistic neural network...
Purpose The purpose of this study was to examine the impact five key build parameters – layer thickness, deposition angle, infill, extrusion speed and temperature, their interactions on maximum flexural force in specimens which are made polylactic acid (PLA). Design/methodology/approach Through a previous properties PLA specimens, statistically significant effect thickness indicated, requiring further experimentation establish values quadratic term model, as well perform optimization....
Purpose This study aims to investigate the impact of layer thickness, extrusion temperature, speed and build plate temperature on tensile strength, crystallinity achieved during fabrication (herein, in-process crystallinity) mesostructure Poly(lactic acid) specimens. Both strength were optimized verified as function processing parameters, their relationship was thoroughly examined.

AimTo analyze the influence of cavity design preparation on stress values in three-dimensional (3D) solid model maxillary premolar restored with resin composite.Methods3D second was designed using computed-tomography (CT) data. Based a factorial experiment, 9 different mesio-occlusal-distal (MOD) designs were simulated, three wall thicknesses (1.5 mm, 2.25 3.0 mm), and cusp reduction procedures (without reduction, 2.0 mm palatal buccal reduction). All MOD cavities simulated direct composite...
Single point incremental forming (SPIF) is one of the most promising technologies for manufacturing sheet metal prototypes and parts in small quantities. Similar to other processes, design SPIF process a demanding task. Nowadays, usually performed using numerical simulations virtual models. The modelling faces several challenges, including extremely long computational times caused by tool paths complexity problem. Path determination also This paper presents finite element (FE) analysis an...
An endodontically treated tooth with mesial-occlusal-distal (MOD) cavity is often restored composite resin. Palatal and buccal cusp reduction (MODP, MODPB), and/or fiber-reinforced posts (P), are used in an attempt to improve the longevity of restoration. The aim this study was determine effects these procedures on von Mises stress values distribution dental tissues restorative materials using finite element analysis. Based CT scans extracted second upper premolar, six 3D models (MOD, MODP,...
