NEW DIRECTIONS IN STRUCTURAL HEALTH MONITORING
作者：Khalid Mosalam , Sifat Muin , Yuqing Gao
来源：[J].NED University Journal of Research, 2019, pp.77 - 112NED工程技术大学
摘要：This paper presents two on-going efforts of the Pacific Earthquake Engineering Research (PEER) center in the area of structural health monitoring. The first is data-driven damage assessment, which focuses on using data from instrumented buildings to compute the values of damage f...

    SEISMIC RETROFIT OF NONDUCTILE REINFORCED CONCRETE FRAME AND MASONRY BUILDINGS
    作者：Murat Saatcioglu
    来源：[J].NED University Journal of Research, 2019, pp.143 - 164NED工程技术大学
    摘要：A large proportion of existing building and bridge infrastructure across the world consists of seismically deficient non-ductile structural systems. Performance of structures during recent earthquakes have demonstrated seismic vulnerability of these systems, the majority of which...

      SEISMIC VULNERABILITY AND RETROFIT METHODOLOGIES IN MEDIUM-LENGTH REINFORCED CONCRETE BRIDGES
      作者：Jose Manuel Jara , Bertha Alejandra Olmos , Guillermo Martínez
      来源：[J].NED University Journal of Research, 2019, pp.129 - 142NED工程技术大学
      摘要：An important number of short and medium span bridges in the world were built before 1970. Particularly, in Mexico, the typical structural configuration of these bridges is a simple supported concrete deck on reinforced concrete beams, for two lane roads. Just a few of them have b...

        GEOPOLYMER CONCRETE AT AMBIENT AND ELEVATED TEMPERATURES: RECENT DEVELOPMENTS AND CHALLENGES
        作者：Zhong Tao , Zhu Pan
        来源：[J].NED University Journal of Research, 2019, pp.113 - 128NED工程技术大学
        摘要：Geopolymer concrete (GPC) is attracting increasing attention due to its potential to replace ordinary Portland cement (OPC) concrete to reduce the carbon dioxide emissions from cement production. Although extensive research has been conducted in this area since the 1970s, its app...

          EXPONENTIATED HALF-LOGISTIC LOMAX DISTRIBUTION WITH PROPERTIES AND APPLICATION
          作者：Farrukh Jamal , Hesham Mohammed Reyad , Soha Othman Ahmed ...
          来源：[J].NED University Journal of Research, 2019, Vol.XVI (2), pp.1 - 11NED工程技术大学
          摘要：A new three-parameter continuous model called the exponentiated half-logistic Lomax distribution is introduced in this paper. Basic mathematical properties for the proposed model were investigated which include raw and incomplete moments, skewness, kurtosis, generating funct...

            SUPPRESSION OF CROSS-TERM IN WIGNER DISTRIBUTION USING DIRECTIONAL FILTERING AND IMAGE PROCESSING
            作者：Sadiq Ali , Nabeel Ali Khan
            来源：[J].NED University Journal of Research, 2019, Vol.XVI (2), pp.23 - 29NED工程技术大学
            摘要：Cross-term suppression in the Wigner distribution is a challenging task. Kernel based schemes are most widely used for reducing cross-terms. However, these schemes suffer from the intrinsic give and take between auto-term resolution and cross-term suppression. This paper presents...

              EXPERIMENTAL INVESTIGATION OF FLOW RESPONSE TO STATIONARY DISTURBANCE IN ROTATING-DISK FLOW
              作者：Muhammad Ehtisham Siddiqui
              来源：[J].NED University Journal of Research, 2019, Vol.XVI (2), pp.13 - 22NED工程技术大学
              摘要：Three-dimensional boundary-layer flow is well known for its abrupt and sharp transition from laminar to turbulent regime. The presented study is a first attempt to achieve the target of delaying the natural transition to turbulence. The behaviour of two different shaped and sized...

                HYBRID ITERATIVE LEARNING CONTROL FOR POSITION TRACKING OF AN ELECTRO HYDRAULIC SERVO SYSTEM
                作者：Mansoor Zahoor Qadri , Ahsan Ali , Inam-ul-Hassan Sheikh
                来源：[J].NED University Journal of Research, 2019, Vol.XVI (2), pp.31 - 42NED工程技术大学
                摘要：Accurate position control of an electro hydraulic servo system (EHSS) is a challenging task due to inherent system nonlinearities, parametric variations and un-modelled dynamics. Since feedback controllers alone cannot provide perfect tracking control, an integration of feedback ...

                  DESIGN OF A PRACTICALLY FABRICATED MINIATURE SIZE PATCH ANTENNA
                  作者：Gulzar Ahmad , Asif Sultan , Muhammad Inayatullah Khan Babar ...
                  来源：[J].NED University Journal of Research, 2019, Vol.XVI (2), pp.43 - 52NED工程技术大学
                  摘要：This paper presents the results of simulation and experimental investigations on a locally fabricated patch antenna using a high dielectric ceramic (alumina) substrate. The antenna was designed for a centre frequency of 6.32 GHz within C-Band which was excited using micro-strip l...

                    SEISMIC BEHAVIOUR OF NOVEL INTEGRAL ABUTMENT BRIDGES
                    作者：Bruno Briseghella , Fuyun Huang , Gabriele Fiorentino
                    来源：[J].NED University Journal of Research, 2019, pp.1 - 20NED工程技术大学
                    摘要：Integral abutment bridges (IABs) are becoming rather common due to the durability problems of bearings and expansion joints. Monolithic connections between the deck and sub-structure allow, on one side, to increase the structure redundancy and reduce the maintenance costs. Howeve...
