Automated Disassembly

The paper deals with the feasibility of a flexible robotic cell for the disassembly of electronic components. First, the need for an automated process for the end of life management of electronic boards is motivated: the reuse of electronic components represents a potential cost saving opportunity for a class of electronic board producers, other than an effective means to improve the waste management efficiency and the sustainability of the electronics sector. Then, starting from a state of the art survey, a technical implementation of the cell is proposed. Finally, some preliminary tests of the disassembly equipment, aimed at setting the most relevant process parameters, are described.

The improvement of the waste management efficiency and sustainability in the electronics sector requires the disassembly and reuse of valuable electronic components, instead of their recycling for precious materials recovery. In this context, this study proposes a robotic system for the disassembly of electronic components, grounded on the revamping of an existing soldering machine. First, the feasibility of an automated process for the end of life (EoL) management of electronic boards is investigated: the disassembly and reuse of electronic components represents a potential cost saving opportunity for producers of industrial electronic boards, other than an effective means to improve the environmental sustainability of the electronics sector. Then, the automatic system has been designed; it is mainly composed by a wave soldering machine, a two-axis manipulator equipped with a suction cup for components picking, and a central control unit to coordinate the motion. Finally, the prototype of the disassembly equipment has been realized. The experimental tests aimed at setting the most relevant process parameters (e.g., working temperatures) and verifying the performance of the developed disassembly equipment. Results confirmed the effectiveness and the reliability of the prototype: all the 450 microprocessors disassembled from 50 boards resulted to be not damaged and thus directly reusable in new boards without the need of additional treatments (e.g., washing).

This paper presents the development of an artificial intelligent algorithm to control circuits structuring of flexible remote experiments in engineering fields of electronics and electricity within a switching matrix architecture. In addition, this paper presents a technical analyze and characterization of VISIR system to point itsadvantages and its inconveniences.The developedartificial intelligent algorithm controlsthe interconnections between electrical and electronic components and monitorsthe power supplying and measurements conducting onVISIR system.We also developed an electronic board to provide the physical possibility of connecting any component to any other component on VISIR’s switching system, and thereby manifesting a switching matrix architecture within VISIR. The developed switching matrix architecture and the developed algorithm enable to have flexible remote experiments in engineeringfields of electronics and electricitywhile havingresilient control on circuits structuring for e-learning purposes.Inaddition, they open the way to havemore circuit combinations of experiments by offering the possibility of connecting any component to any other componentwhile respecting the electrical limits of current and voltage.

Abstract BACKGROUND: Intrawound vancomycin powder has been studied extensively in spinal fusion surgeries and been found to reduce rates of surgical site infections (SSIs) significantly. Despite its success in spinal surgeries, topical vancomycin has not been extensively studied with respect to cranial neurosurgery. OBJECTIVE: To evaluate the efficacy of intrawound topical vancomycin for prevention of SSIs following open craniotomies. METHODS: We retrospectively analyzed a large series of 350 patients from 2011 to 2015 in a pre/postintervention study of use of topical vancomycin to reduce postoperative craniotomy infection rates. We had a preintervention control group of 225 patients and a postintervention group of 125 patients that received intrawound topical vancomycin. RESULTS: Our preintervention incidence of SSI was 2.2% and this was significantly reduced to 0% following introduction of topical vancomycin (P < .5). An ad hoc cost analysis suggested a cost savings of ${\$}$59 965 with the use of topical vancomycin for craniotomies. CONCLUSION: Our study found a significant reduction in SSI rates after introduction of topical vancomycin. Thus, this simple intervention should be considered in all open craniotomy patients as both infection prophylaxis and a potential cost saving intervention.

AbstractStructural variants (SVs) remain challenging to represent and study relative to point mutations despite their demonstrated importance. We show that variation graphs, as implemented in the vg toolkit, provide an effective means for leveraging SV catalogs for short-read SV genotyping experiments. We benchmarked vg against state-of-the-art SV genotypers using three sequence-resolved SV catalogs generated by recent long-read sequencing studies. In addition, we use assemblies from 12 yeast strains to show that graphs constructed directly from aligned de novo assemblies improve genotyping compared to graphs built from intermediate SV catalogs in the VCF format.
