A new approach for climbing hard vertical surfaces has been developed that allows a robot to scale concrete, stucco, brick and masonry walls without using suction or adhesives. The approach is inspired by the mechanisms observed in some climbing insects and spiders and involves arrays of microspines that catch on surface asperities. The arrays are located(More)
We report on a series of 25 patients (26 cases) presenting an association of Wartenberg's radial neuritis and De Quervain's tenosynovitis. In all patients the diagnosis was made on clinical grounds. In group 1, conservative treatment of Wartenberg's syndrome was used in 16 patients (associated with surgical release of the first extensor compartment in 5(More)
Between March 1977 and December 1991, 98 surgical procedures on 85 patients were performed at SOS Main Strasbourg for osteoarthrosis of the carpometacarpal joint of the thumb. The mean age was 56 and 90% were female; 13 were operated on bilaterally. 40% had Swanson arthroplasties (group 1), 15% Ashworth-Blatt hemiarthroplasties (group 2), and 45% had soft(More)
The novel adhesive effects of magnetorheological fluid for use in climbing robotics were experimentally measured and compared to existing theoretical models. Contrary to these models, the fluid thickness between two parallel plates was found to have little effect on the adhesive failure strength and a positive effect on time to failure. Target surface(More)
The proposed hybrid stage shop scheduling (HSSS) model, inspired from a real case in the high-fashion industry, aims to fully exploit the potential of parallel resources, splitting and overlapping concurrent operations among teams of multifunctional machines and operators on the same job. The HSSS formally extends mixed shop scheduling (a combination of(More)
The most general flowshop scheduling problem is also addressed in the literature as nonpermutation flowshop (NPFS). Current processors are able to cope with the (n!) m combinatorial complexity of non-permutation flowshop scheduling by metaheuristics. After briefly discussing the requirements for a manufacturing layout to be designed and modeled as(More)
The results of a two-center clinical study on the use of the 3M Precise Microvascular Anastomotic System in microvascular procedures for hand trauma are presented. Since November 1992, 17 patients (age range, 18-76 years) have received an end-to-end vascular anastomosis using this device. All patients had vascular trauma or amputation requiring replantation(More)
We compared 3 methods of treatment of trapezometacarpal arthritis: partial trapezectomy with Ashworth Blatt interposition and total trapezectomy with either Swanson spacer or anchovy procedure. Out of a series of 85 patients (98 operations), 52 (62 operations) were reviewed by an independent observer after a mean follow-up of 5 years. Silicone spacers were(More)
