In this paper the workspace and payload capacity of a new design reconfigurable Delta-type parallel robot is analysed. The reconfiguration achieved by adjusting length kinematic chains given link simultaneously symmetrically during operation robot. This would produce dynamic in shape volume. A numerical analysis variation volume presented. Based both on results practical requirements, proposal for reconfiguring mechanism
Persimmon fruit processing-derived waste and by-products, such as peels pomace, are important sources of dietary fiber phytochemicals. Revalorizing these by-products could help promote circular nutrition agricultural sustainability while tackling deficiencies chronic diseases. In this study, fiber-rich fractions were prepared from the Sharoni Brilliant Red persimmon varieties. These quantified for their phenolic composition assessed ability to growth beneficial human colonic Firmicutes...
This paper presents a new version of the camera-space-manipulation method (CSM). The set nonlinear view parameters classic CSM is replaced with linear model. Simulations and experiments show similar precision error for two methods. However, approach simpler to implement faster.
Transparent monolithic gels were prepared from the cohydrolysis of diethylphosphatoethyltriethoxysilane (OC2H5)2P(O)CH2CH2Si(OC2H5)3 (SiP) and tetraethoxysilane Si(OC2H5)4 (TEOS) in various ratios, under acidic conditions. The hydrolysis initial polycondensation SiP studied by high-resolution 29Si-NMR. Based on signal intensities, singnals due to following oligomers identified: R(OH)2SiOSi(OH)(R)OSi(OH)2, R(OH)2SiOSi(OH)2, R(OH)(OEt)SiOSi(OH)2R, R(OH)2SiOSi(OH)(R)OSi(OH)2R [R(OH)SiO-]-3....
In this paper we present a new methodology to achieve vision-based control using mobile manipulator reach required three-dimensional target position and orientation. Examples of manipulators include standard forklifts backhoes, which have fixed mounted on platform. The overall objective is apply the nonholonomic degrees freedom represented by two independently driven wheels together with holonomic dexterity on-board arm in order bring about desired positioning for arm.

We created a sensor-fusion suite for the acquisition of biometric information that can be used estimation human control strategy in variety everyday tasks. This work focuses on experimental validation integrated motion capture subsystem based raster images. Understanding strategies utilized activity requires measurement several variables grouped as kinematic, dynamic, and biological-feedback variables. Hence, there is strong need acquisition, analysis, synchronization measured by...
This work proposes a set of simulation and experimental measurements to estimate muscle biomechanical parameter during human quiet standing. Understanding the mechanisms involved in postural stability is indispensable improve knowledge how humans can regain balance against possible disturbances. Postural requires ability compensate movement body’s center gravity caused by external or internal perturbations. paper describes implementation hybrid parameter-estimation approach infer features...

Postural is an integral task to daily living reliant upon ankle hip. To this end, estimation joint parameters can be a useful tool when analyzing compensatory actions aimed at maintaining postural stability. Methods Using analytical approach, study expands on previous work analyzes two degrees freedom human model. The first modes vibration system are...

Our approach consists collecting exposing them reagents activate amplify light emission produced...
This paper presents the theoretical development and experimental implementation of a sensing technique for robust precise localization robotic wheelchair. Estimates vehicle’s position orientation are obtained, based on camera observations visual markers located at discrete positions within environment. A novel particle filter sensor space (Camera-Space Particle Filter) is used to combine with sensed wheel rotations mapped onto through an observation function. The fuses odometry vision...
Abstract Mass transfer through a liquid membrane was studied in macroscopic setup that allowed an estimate of the resistance to interface crossing. It found interfacial associated with phase behavior and physicochemical formulation surfactant‐oil‐water system. The mass closely followed variation tension, i.e., it minimal at optimal so‐called Winsor III systems.
ABSTRACT In this work we studied the influence of membrane hydrophobicity on filtration oil/water (O/W) emulsions with a dispersed phase content 30% (V/V). The process was realized by using ceramic tubular hydrophilic or hydrophobic membranes different mean pore size (0.2 pm, 1.2 and 1.4 pm radius). Hydrophobic character obtained modifying superficially surface very thin polymer layer. results showed that emulsion viscosity droplet distribution depend shearing forces transmembrane pressure....
