Innovative design technology: An optimal surgical aid system for Hip Resurfacing Arthroplasty

Hip Resurfacing Arthroplasty (HRA) is a treatment option for the patients with the advanced hip disease; it is considered as the most technically difficult techniques of all procedures recommended for osteonecrosis of the hip. Technically, the currently applied HRA surgeries lead to unstable and inconsistent results. Surgeons rely a lot on the manual technique and conventional tools as well as their skills to determine the right drilling angle for locating the implant system. Although the robotic and surgical planning systems are available for HRA, the drilling line is still defined geometrically and intra-operatively, not fully considering about the biomechanics aspects of the implant and bone structure. In this paper, an optimal surgical aid system for HRA is proposed. With the integration of the state of the art biomedical modelling, pre-operative planning and personalised surgical tools, knowledge based and expert system, as well as biomechanics modelling and analysis, the precision, safety and speed of surgery are improved, the complexity of surgery is reduced, and therefore the survival rate of the implant is increased. Especially, the proposed system provides a cheap and practically feasible solution with the integration of expertise from both engineering and medicine for improving the treatment quality of the patients

An adaptive image inpainting method based on the modified mumford-shah model and multiscale parameter estimation

Image inpainting is a process of filling missing and damaged parts of image. By using the Mumford-Shah image model, the image inpainting can be formulated as a constrained optimization problem. The Mumford-Shah model is a famous and effective model to solve the image inpainting problem. In this paper, we propose an adaptive image inpainting method based on multiscale parameter estimation for the modified Mumford-Shah model. In the experiments, we will handle the comparison with other similar inpainting methods to prove that the combination of classic model such the modified Mumford-Shah model and the multiscale parameter estimation is an effective method to solve the inpainting problem

Ultraviolet Complete Electroweak Model Without a Higgs Particle

An electroweak model with running coupling constants described by an energy dependent entire function is utraviolet complete and avoids unitarity violations for energies above 1 TeV. The action contains no physical scalar fields and no Higgs particle and the physical electroweak model fields are local and satisfy microcausality. The $W$ and $Z$ masses are compatible with a symmetry breaking $SU(2)_L\times U(1)_Y \rightarrow U(1)_{\rm em}$, which retains a massless photon. The vertex couplings possess an energy scale $\Lambda_W > 1$ TeV predicting scattering amplitudes that can be tested at the LHC.Comment: 19 pages, no figures, LaTex file. Equation and text corrected.

A taxonomy of information-centric networking architectures based on data routing and name resolution approaches

This study presents a vast coverage of current Information-Centric Network (ICN) submission by evaluating eight distinct and popular routing and name resolution approaches.Internet build-up and initial deposition were based on a host-driven approach.With the increasing demands for mediadriven data flooding the cost of the Internet, a new semantic and paradigm shift was envisioned known as ICN.Information Centrism is an approach that partly dissociates the host dependencies by referring to contents by unique identifiers called name.However, to benefit from the content network, forwarding, naming and routing, among other issues are still in its developmental stages.The taxonomy serves as a basis for research directions, challenges, implementation and future studies for standardizing the ICN routing and naming. Routing and Name Resolution were themed in categories of strategies, contributions, issues and drawbacks. The major findings of this paper are providing a classification and review of the data routing and name resolutions approaches that are proposed on eight ICN architectures; presenting drawback areas in the selected architectures; and finally highlighting some challenges of ICN routing for the ICN research community vending

Crystal structure of (1RS,21SR,22RS,24SR)-28-oxo-24-propyl-8,11,14-trioxa-24,27-diazapentacyclo[19.5.1.122,26.02,7.015,20]octacosa-2,4,6,15(20),16,18-hexaene acetic acid monosolvate

The title compound, C26H32N2O4(M)·C2H4O2, (I), is the product of the Petrenko-Kritchenko condensation of N-propylpiperidinone with 1,5-bis(2-formylphenoxy)-3-oxapentane and ammonium acetate. In M, the aza-14-crown-3-ether ring adopts a bowl conformation, with the configuration of the C - O - C - C - O - C - C - O - C polyether chain being t-g (-)-t-t-g (+)-t (t = trans, 180°; g = gauche, ±60°). The dihedral angle between the planes of the benzene rings fused to the aza-14-crown-4-ether moiety is 62.75 (5)°. The central piperidinone ring has a boat conformation, whereas the terminal piperidinone ring adopts a chair conformation. The boat conformation of the central piperidinone ring is supported by the bifurcated intramolecular N - H⋯O hydrogen bond. In the crystal, each solvent molecule is linked to molecule M via strong O - H⋯N hydrogen bonding, forming hydrogen-bonded pairs of molecules, which further interact through weak C - H⋯O hydrogen bonds, forming layers parallel to the ac plane. © 2016
