This paper presents the design and preliminary performance assessment of a full-body assistive exoskeleton(AXO-SUIT)for older ***-SUIT is a system that consists of separate lower-body and upper-body modular exoskeletons,which can be combined to form a full-body system to provide flexible physical assistance as *** full-body exoskeleton comprises 27 degrees of freedom(dof),of which 17 are passive and 10 *** can assist people in walking,standing,carrying and handling tasks.A user-centered design approach was adopted throughout the development of the *** paper describes the design process of AXOSUIT,involving a review of user needs,a kinematic and kinetic motion study,and innovative system *** with the developed systems were conducted on selected end-user subjects,covering both performance evaluations at different levels and useability ***-user testing results show the effectiveness of the exoskeleton in providing flexible physical assistance.

城市化进程的加快意味着城市和国际组织需要去寻找各种能够提高能源效率和减少空气中污染物排放的方法。冷热电联产(CCHP)系统可以同时供暖、制冷和发电,具有提高城市或城市区域能源发电效率的潜力。本研究的目的是在满足建筑热需求(供热和制冷)的各种运行条件下,对亚特兰大大都市区内的五种常见建筑类型在采用CCHP系统时的发电耗水、CO_2和NO_x排放,及其经济性进行评价。对于大多数采用或不采用净计量策略的建筑类型来说,以满足每小时热需求去运行CCHP系统均可减少CO_2的排放量。该系统能否对这些建筑类型产生经济效益,主要取决于天然气的价格、净计量策略的采用和假定的CCHP系统的成本结构。当建筑物采用净计量策略并且CCHP系统是以满足建筑物每年的最大热需求而运行时,CCHP系统的发电耗水量和NO_x的排放量均有最大限度的减少,尽管此时该运行情景会增加温室气体排放和发电成本。CCHP系统对中型办公楼、大型办公楼和多户型住宅建筑更经济、实用。

The present research work deals with an extension of a previous work entitled [Exact Soliton-like spherical symmetric solutions of the Heisenberg-Ivanenko type nonlinear spinor field equation in gravitational theory, Journal of Applied mathematics and Physics, 2020, 8, 1236-1254] to Analytical Soliton-Like Solutions to Nonlinear Dirac Equation of Spinor Field in Spherical Symmetric metric. The nonlinear terms in the Lagrangian density are functions of the invariant mg src="Edit_***" alt="" />. Equations with power and polynomial nonlinearities are thoroughly scrutinized. It is shown that soliton is responsible for the deformation in the metric and hence in the geometry as well as gravitational field. The role of nonlinearity and the influence of the proper gravitational field of the elementary particles are also examined. The consideration of the nonlinear terms in the spinor Lagrangian, the own gravitational field of elementary particles and the geometrical properties of the metric are necessary and sufficient conditions in order to obtain soliton-like solutions with total charge and total spin in general relativity.

拥有多座大坝的大坝业主经常面临的困难挑战是需要对不同严重程度的大坝安全缺陷进行排序。监管者和企业利益相关者要求资本性支出均合情合理,所有决策制定都具有透明性。大坝资产管理者必须能总结和持续监测资产中大坝的健康和风险,并将这些信息以一种明确和简单易懂的方式传达给企业高管、董事会和监管者。笔者介绍了一种确定大坝安全修复工程优先性的方法,它基于大坝的物理状态、大坝在各潜在溃坝模式下的各设计荷载工况中的病险程度、出现设计荷载工况的概率和大坝溃决的后果。它使用大坝安全复核中已有的信息,不需要再做额外的工程研究。文中还给出了一个标准的电子表格格式,用于存储大坝安全信息并着手风险评估和大坝安全修复工程的优先排序。该电子表格还用于提供优先排序过程中的透明性和总结关于大坝健康的关键信息。大坝资产管理者可使用这些关键信息以一种系统的、透明的方式管理大坝,该方法易于被公司高管、董事会和监管者理解和接受。
