Automatic processing and full analysis of in situ liquid phase scanning transmission electron microscopy (LP-STEM) acquisitions are yet to be achievable with available techniques. This is particularly true for the extraction information related nucleation growth nanoparticles (NPs) as several parasitic processes degrade signal interest. These degradations hinder use classical or state-of-the-art techniques making understanding NPs formation difficult access. In this context, we propose...
Individuals are more accurate in performing body-related perceptual tasks when viewing their own body-parts compared to those of others. This self-advantage phenomenon revealed an implicit (i.e., task irrelevant) recognition process one’s body. Indeed, no appears participants have recognize body parts explicitly. Whether this extends movements remains unknown. Here, we investigated hypothesis and the role vision proprioception explicit actions. In task, judged perceived lateral direction...
This paper presents a new gravity compensation method for an upper extremity exoskeleton mounted on wheel chair. device is dedicated to regular and efficient rehabilitation training post-stroke injured people without the continuous presence of therapist. The wearable robotic attached human arm. user provides information signals controller by means force sensors around wrist arm, robot generates appropriate control different strategies paradigms. covers four basic degrees freedom shoulder...
This paper presents a novel bilateral control scheme for pneumatic teleoperation systems that are actuated by low cost solenoid valves. A sliding mode is incorporated into two-channel, architecture involving position-position, force-force, or force-position schemes. An analysis of stability and transparency the closed-loop system carried out. The proposed design verified on single-degree-of-freedom with four on/off Moreover, simulation results demonstrate high accuracies in terms position...
In past research on the control of pneumatic actuators, typically proportional servovalves have been used for achieving high-performance mass flow rate. this brief, we instead use fast-switching ON/OFF valves due to their distinct advantages in terms low cost and small size. Accurate actuators with solenoid is a challenge since system dynamics both discrete input highly nonlinear. apply hybrid algorithm actuator valves. Such approach developed choosing best vector at each sample time track...
Articular and soft tissue punctions or injections are widely used for the diagnosis treatment of rheumatic disorders. Ultrasound is increasingly to guide these interventions in order correctly position needle target area, thereby improve efficiency safety procedure. During their learning, medical students need practice master manipulation ultrasound probe at same time acquire enough skills before practicing a real patient. To offer risk-free training apprentices, we present this paper design...
This paper aims to highlight the benefits of simulator training in obstetric manipulations such as forceps blade placement. The BirthSIM is used mimic operative vaginal deliveries. To characterise placement, we studied curvature path. orientation blades are quaternion unit space ensure time-independent analysis. results showed progress for all novices Simulator helps them develop their self-confidence and acquire experience before working delivery room.
Because our civilization has relied on pesticides to fight weeds, insects, and diseases since antiquity, the use of these chemicals become natural exclusive. Unfortunately, progressively had alarming effects water quality, biodiversity, human health. This paper proposes improve farming practices by replacing with a laser-based robotic approach. study focused neutralization aphids, as they are among most harmful pests for crops complex control. With help deep learning, we developed mobile...
Today, medical simulators are increasingly gaining appeal in clinical settings. In obstetrics childbirth provide a training and research tool for comparing various techniques that use obstetrical instruments or validating new methods. Especially the case of difficult deliveries, instruments-such as forceps, spatulas, vacuum extractors-has become essential. However, such increase risk injury to both mother fetus. Only experience acquired delivery room enables health professionals reduce this...
In obstetrics, manipulations are mainly learned during real deliveries. To minimize the risks linked to such training, we propose a childbirth simulator as teaching tool in hospitals. More specifically, focus on training with forceps obstetric manipulation.The method can be divided into two steps: of placement, and extraction manipulation. this paper manipulation analysis results, taking account several parameters using an evaluation function obtain global score.Experimental results reveal...
This paper presents a new predictive hybrid control law for the of electro-pneumatic systems using solenoid valves. The method is based on model mass flow rate In order to evaluate this strategy, comparison study in simulation has been performed with classical PWM force tracking problem. results show that accuracy steady state but also dynamic behavior pressures are better case than control. validity theory verified through simulations.
Endovascular surgery is performed by placing a catheter through blood vessels. Due to the fragility of arteries and difficulty in controlling long elastic wire reach target region, training plays an extremely important role helping surgeon acquire required complex skills. Virtual reality simulators augmented systems have proven be effective minimally invasive surgical training. These systems, however, often employ pre-captured or computer-generated medical images. We developed system for...
This paper presents a new predictive hybrid control law for pneumatic teleoperation system using solenoid valves. Based on model of the mass flow rate valves, this method is used within four-channel (4CH) bilateral architecture haptic teleoperation. An analysis controller parameters carried out in order to achieve acceptable performances. To evaluate strategy, comparison study has been performed with classical PWM system. The results show that accuracy position and force tracking steady...
In modern medical diagnostics, magnetic resonance imaging (MRI) is an important technique that provides insights into anatomical structures. This paper presents a comprehensive methodology focusing on streamlining the segmentation, reconstruction, and visualization of MRI data for surgical training. Segmentation involves extraction regions with help state-of-the-art deep learning algorithms. Then, 3D reconstruction converts segmented from previous step multiple representations. Finally,...
Today, medical simulators are increasingly gaining attraction in clinical settings.
