Systems and Applications

The synergetic integration of mechanical processes, microelectronics and information processing opens new possibilities to the design of processes as well as for its automatic control. The solution of tasks within mechatronic systems is performed on the process side and the digital–electronic side. As the interrelations during the design play an important role, simultaneous engineering has to take place from the very beginning. Mechatronic systems are developed for mechanical elements, machines, vehicles and precision mechanic devices. The integration of mechatronic systems can be performed by the components (hardware integration) and by information processing (software integration). The information processing consists of low-level and high-level feedback control, supervision and diagnosis and general process management. Special signal processing, model-based and adaptive methods are applied. With the aid of a knowledge base and inference mechanisms, mechatronic systems with increasing intelligence will be developed. The main goals are to increase systems performance, reliability and economy, and decrease production costs. Key words: adaptive control; electronics; fault diagnosis; fuzzy control; hardware-in-the-loo

Design of a compact laparoscope manipulator with releasable hybrid control

Twenty years ago, the emergence of endoscopic technology opened up the way to minimal access surgery, which strongly reduced operative traumatisms and significantly improved the patient’s comfort. Nowadays, manipulation of the scope tends to be entrusted to a robot controlled by the surgeon, so as to allow the latter to work without the need of an assistant and to guarantee the stability of the image. However, current robots remain quite expensive and suffer from many limitations : bulk, ergonomics, set-up time, restricted control etc. The purpose of this research is to develop a new compact manipulator which is quick to install, equipped with a hybrid control including optic tracking so at to maintain the field of vision, and allowing a manual manipulation of the laparoscope to permit a short general exploration

With the static #global growth 🌏 of the #biomass-derived #fuel #supplychain, coupled with their inclusion in the long-term #decarbonization of many transport enterprises, the sector still addresses the following #questions: are the emerging technologies assessing the #sustainability and #scalability of biofuels? and if so, what are the #challenges in the implementation of the future global #energy– #water–#climate #nexus? Despite #hydrothermal #liquefaction (HTL) being a competitive technology and apart from #crudeoil as the target product, the major challenge limiting the economic viability and technical scalability of the HTL-related process is the safe disposal of generated by-products, including nearly 25 wt.% to 50 wt.% post-hydrothermal #aqueous #phase (HTL-AP 💧) and 5 wt.% to 20 wt.% solid #hydrochar residues (HCs). #Integrating #adsorbents such as commercially #activatedcarbon and #zeolites can be a potential step to the removal of xenobiotic and recalcitrant #organic and #nutrient compounds from HTL-AP. However, these expensive adsorbents require a substitute for adsorption sustainability. Solid HCs, which are generated from HTL with carbon as the major element, can be used as low-cost adsorbents. However, its #porosity of 0.058–0.082 cm3/g and BET-specific surface area of 1.56–17 m2/g remain comparatively low because of the formation and condensation of hydrocarbons on the surface, thereby clogging pores and reducing its #adsorption capacity. To the best of our knowledge, existing HTL studies have well-characterized crude bio-oils but have not focused on hydrochar except for primary details such as yield and ultimate analysis. Furthermore, the use of HTL hydrochar as an alternative low cost for #commercial adsorbents and #wastewater #remediation purposes is very less explored in comparison to pyrolytic char. Hence, the focus of our just available online accepted article is to contribute to the knowledge development of these #gaps

Design and realization of a new backdrivable laparoscope manipulator

Twenty years ago, the emergence of endoscopic technology opened up the way to minimal access surgery. These new types of procedures strongly reduced operative traumatisms by requiring only small incisions in order to insert long instruments through the abdominal wall. The scars are barely visible, and the recovery period is shortened so that the patient resumes his normal life sooner. Nowadays, manipulation of the scope tends to be entrusted to a robot controlled by the surgeon, so as to allow the latter to work without the need of an assistant and to guarantee the stability of the image. However, current robots remain quite expensive and suffer from many limitations : bulk, lack of ergonomics, long set-up time, restricted control and simple motions etc. The purpose of this research is to develop a new compact manipulator which is quick to install, requires no adaptation to the patient or type of procedure, allows a manual manipulation of the laparoscope to permit a short general exploration without releasing it from the robot, and is equipped with user-friendly programming capabilities to enhance safety and ergonomics

A Multi-agent Evolution Algorithm used for Input Shaping of a Repetitive Non-linear Dynamic System

This software uses Matlab/Simulink environment to simulate and optimize the performance of a so-called Digital Displacement Unit (a fluid power technology). It does so iteratively with a custom-made evolution type algorithm which requires little programming effort but yet deploys a priori knowledge of the system. The results and deeper description have/are gonna be presented at the conference on fluid power and motion control in the paper with the name of the title
