An ideal dental implant is a design that maximizes the anchorage strength of implants in human jawbones and minimizes peak stress values in bone-implant interfaces under given standard loads. The stress concentration at the bone-implant contact is controlled by implant design, which determines the bone biological response. Implant design has improved as a result of marketing demands. The modification of shape, size, material, and surface topography of primary designs has been the focus of dental implant design in response to marketing needs. Since the integration of bone-implant has been highlighted in dentistry investigations, improving implant design depends on the prediction of mechanical reactions and remodeling response of bony tissues around implants. There are four types of implants design including Screws, cylinders, Conical cylinders, and Blades type implants. The major difference between these designs is in implant primary stability. With the development of computational technologies, researchers can predict long term oral bone remodeling around implants by use of the finite element method. This review considers the design parameters of dental implants in which affect stress, strain in bone-implant interfaces, and bone remodeling around the implant.

Saving energy and low carbon strategy has becoming the future trend of manufacturing industry. Cutting process in mechanical manufacturing has the characteristics of heavy energy consumption and complex process. The estimation and evaluation of energy consumption and energy efficiency of cutting process are hot topics in research groups and industry. The energy consumption of cutting process is determined by the load, which is related to the cutting parameters under fixed cutting systems, while the cutting parameter might change with the cutting process and material. Based on the relationship between energy consumption and cutting characteristics and the quality requirements, the cutting specific energy u(t) = P(t)/M(t), which is varies with time is proposed to evaluate the energy consumption of various cutting parameters under complex machining processes. The influence of cutting parameters on cutting energy consumption is studied by experiments and a calculation method is proposed to calculate cutting energy consumption. Finally, a case study of complex curve machining in mold manufacturing is illustrated to prove the effectiveness of the proposed evaluation method.

The study of earthquakes losses in buildings has traditionally been approached for a single amplification factor of the design spectrum, but it could be useful to use other amplification factors to reduce costs. This paper analyzes the evolution of seismic damage costs in three models based on the performance level achieved by these structures, as well as the amplification factor of the design spectrum. Three nonlinear analytical models of reinforced concrete were analyzed. Each model differs in dynamic characteristics and was designed by scaling the design spectrum for three amplification factors. A firm soil earthquake was analyzed, which was scaled to 22 intensities and with this results, dynamic capacity curves of the studied models were constructed. From the analyses it was obtained interstory drift and maximum accelerations, with which the following seismic damage costs were estimated: structural and non-structural damage, contents replacement, income and profits, injuries and deaths. The results show different types of relations between intensity and each type of loss. They also justify the importance of introducing amplification factors at the design stage to minimize the cost of a particular type of damage.

Dynamic characteristic analysis is the key step to improve the transmission performance of eccentric permanent magnet gear. The study of this step can not only analyze the dynamic force process of each transmission part, but also improve the operation stability and bearing capacity of eccentric permanent magnet gear. Taking three-shaft ring-plate magnet gear (TRMG) as the research object, based on its operation mechanism and dynamic model, this paper establishes the balance equation of force and torque of each part of TRMG. Through the combination of electromagnetic finite element simulation and mathematical analysis method, the force of the input shaft and the supporting shaft in the TRMG motion process is solved. By improving the TRMG power input mode, the dynamic performance of TRMG is optimized, and the stability of transmission structure is improved. The feasibility of this new transmission mode is verified by multi-body dynamics analysis.

The information has been used to estimate the total SF{displaystyle _{6}} mass in the current fleet and to determine historical emissions. The environmental and economic impacts are evaluated using the obtained results on simple models. Recommendations are made in order to mitigate the estimated impacts.

Beams on elastic foundation are basic elements within structural analysis, which are used to model foundation beams, foundation piles, retaining walls, and more complex structures that include some of these elements. For their analysis, the finite element method is usually used [1], which produces an approximate solution of the problem; and the Green's function stiffness method [2], which produces an exact solution. This article presents a methodology 100% based on the use of Green function's (response to a unit point force), to obtain the exact response of beams on elastic foundation. The main advantage of this formulation is its computational low cost compared to the aforementioned alternatives, and even for a large number of problems, it can be expressed only by means of sums and integrals, which can be easily performed numerically. Also, a great variety of Green function's for finite and infinite beams on elastic foundations with different boundary conditions are also presented, as well as some examples with the implementation of the proposed methodology.

In addition, by considering the stochastic linear restriction for the vector of fixed effects parameters we are introduced the stochastic restricted two parameter estimation. Methods are proposed for estimating variance parameters when unknown. Also, the superiority conditions of the two parameter estimator over the best linear unbiased estimator, and the stochastic restricted two parameter estimator over the stochastic restricted best linear unbiased estimator are obtained under the mean square error matrix sense. Methods are proposed for estimating of the biasing parameters. Finally, a simulation study and a numerical example are given to evaluate the proposed estimators
