A network (100) for replacement of a living tissue, said network is a scaffold-free artificial hollow biological tissue network comprising a plurality of longitudinal multicellular aggregates (11) arranged in a plurality of bioprinted layers (22) which are located on top of one another, further comprising an inner surface (20) and an outer surface (21), wherein at least one of said bioprinted layers (22) is in shape of a planar closed loop such that a conduit for conveying fluids is defined, and said longitudinal multicellular aggregate (11) is a mixture of at least two cell types. Also a method for obtaining said longitudinal multicellular aggregate, and a further method for biomodeling and planning said network are proposed.
摘要:
It is proposed a design and control of series elastic holonomic mobile platform, aimed to administer therapeutic table-top exercises to patients who have suffered injuries that affect the function of their upper extremities. The proposed mobile platform is a low-cost, portable, easy-to-use rehabilitation device for home use. It consists of four actuated Mecanum wheels and a compliant, low-cost, multi degree-of freedom Series Elastic Element as its force sensing unit. Thanks to its series elastic actuation, it is highly backdriveable and can provide assistance/resistance to patients, while performing omni-directional movements on plane. The device helps improving accuracy and effectiveness of repetitive movement therapies completed at home, while also providing quantitative measures of patient progress.
摘要:
The present invention relates to a novel graphene sheet with modulated thickness comprising electrically conductive areas of an array of ridges constituting a grid structure on graphene surface wherein the ridging areas are integrally formed with the graphene sheet and are themselves made of graphene. The invention further relates to a method for producing the thickness modulated graphene material of above type by way of a special capping technique where the capping structure having an array of protrusions is involved so that the said capping would transfer its physical structure to the graphene surface to form areas with improved electrically conductivity and optical transparency.

The present invention proposes a method of communication in a wireless relay network for finding group of relays that minimizes total energy consumption to send one successful bit to destination node, under reliability condition expressed in terms of average BER level, said method comprising three main phases in the manner that a reservation stage where cooperative data transmission request is made by the source node, an ACO epoch, where the announcements of the candidate relays are sent, the cooperation set is formed and power levels are assigned, and the cooperative data transmission stage itself, are defined.
摘要:
A method for automatic printing of a three dimensional heterogeneous structure in accordance with a computer-aided design procedure, including the steps of: aspirating a first portion consisting of a first material (M1) in liquid form, from a first liquid container into a capillary (C); aspirating a second portion consisting of a second material (M2) in liquid form different than the first material (M1), from a second liquid container into said capillary (C), such that the first portion and the second portion constitute longitudinally different parts of a longitudinally heterogeneous filament (F) encompassed by the capillary (C); and extraction of the filament (F) from the capillary (C) thus laying it as a portion of a printed layer.
