The concrete structure remedial assessements in marine environment from whole life asset management perspectives

This study makes use of a desk top review methodology to discover and understand the remedial assessment of damage concrete structures in the marine environment (sea water). Basically, the restorations of asset marine facility are done by using a correct and present repair technique to both spall concrete as well as corrode rebar and must follow the code and standards throughout construction periods. Specifically, the study undertook a comprehensive insight into the literature review of three (3) major components of research, consisting of reinforced concrete of marine structure, understanding marine environment and management of rehabilitation marine facility. The research chooses a case study of an oil refinery jetty piles terminal at Marsden Point in New Zealand. The asset facility is poorly deteriorating due to aggressive action of marine environment and need attention. The asset owners are aim to establish potential maintenance strategies in restoration of his asset facilities. The damaged marine structure will be looked at from whole life asset management perspectives; to identify various components of concrete structures that were subjected to steel corrosion and concrete deterioration. Application of whole life asset management paradigm in the case study will have significant impacts to the facilities and the owner as well. The benefits with regard to implementation of whole life asset management approaches in managing the asset marine facility correlate with risk management, accountability, service facility management and financial efficiency. The refurbishment work will make use of current repair method in assessing the restoration of damage concrete piles. This should take account of a risk management study prior selection of best procurement routes for the case studies. The case study is critically reviewed for options that suit the asset facility present condition and set up objectives to get the best approach adopted with regards to asset problem. The findings demonstrate that the adoption of the whole life asset management paradigm will promote the asset owner, to obtain best value for money concept from the investment and to gain benefits in terms of time, cost, quality and fit for purpose. It also help in promoting and prolong the asset lifespan and also to provide constant sustainable and economic service of asset facilities

Development of step-compliant system for turn-mill operations

Today with the latest technology the information beyond tool movement and switching instruction such as tooling, manufacturing features and process sequences are needed to support global adaptability for manufacturing with a specific focus on CNC-based manufacture. This research focuses on the use of the new standard; ISO 14649 (STEP-NC), to address the process planning and machining of discrete turn/mill components and proposes a STEP Compliant NC structure for generation of ISO 14646 code which can be used for turning component manufacture. The novel application of this work is STEP-NC compliant process control where the research will utilise and extend the standard for in process measurement at the machine and also explore the application and integration of the STEP-NC standards. The major contribution of this research is the review of a computational environment for a STEPNC compliant system for turn/mill operations by focusing the outlines of the three major CAD/CAM frameworks to support the implementation of the standard with various levels of STEP compliant architecture. Issues related to the implementation of these frameworks and their use with STEP compliant NC controllers provide a major change in the current day use of CAD, CAPP, CAM and CNC systems. This change will bring new challenges to industrial users and software vendors to identify the new boundaries and define intelligent CNC manufacture in the 21st century

Finite element formulation for free vibration of composite beams

Investigations concerning the dynamic response of composite beams with partial interaction are scarce. Derivation of the differential equations describing the interaction between composite elements normally involves with the solution of high order system of equations, which closed form solutions are difficult. This study concerns with the finite element formulation of composite beams for free vibration. The formulation involves with the establishment of the stiffness matrix and the mass matrix of the beam. The former was obtained through extremization of the total potential energy (or Hamilton principle for dynamic) whilst the latter was obtained by lumping the elements mass at nodes. Natural frequencies of the beam were obtained as eigenvalues. These were then verified by existing analytical solution

The role of Zionist movement towards the creation of the state of Israel (Peranan pergerakan zionist terhadap pembentukan negara Israel)

The problem of Palestine has been a subject of much debate not only among scholars but also involved world superpowers as well. As this conflict rages on, there is a need to look at the root cause of the problem which one could argue that, among others, was caused by the ambitions of Zionist Movement. This paper examines the emergence of Zionist Movement and its role in establishing the State of Israel by confiscating Palestinians‟ territory and land. Zionist controls over the territory has resulted in the expulsion of Palestinians from their homeland. This study was conducted as a library research with textual analysis on the sources of Palestine historiography. The result shows that the Zionist Movement had lobbied the world superpowers, especially Britain and United States of America, until they supported the movement and resulting in the creation of the State of Israel on the Palestinian land

Medical image classification and symptoms detection using neuro fuzzy

The conventional method in medicine for brain MR images classification and tumor detection is by human inspection. Operator-assisted classification methods are impractical for large amounts of data and are also non-reproducible. MR images also always contain a noise caused by operator performance which can lead to serious inaccuracies classification. The use of artificial intelligent techniques, for instance, neural networks, fuzzy logic, neuro fuzzy have shown great potential in this field. Hence, in this project the neuro fuzzy system or ANFIS was applied for classification and detection purposes. Decision making was performed in two stages: feature extraction using the principal component analysis (PCA) and the ANFIS trained with the backpropagation gradient descent method in combination with the least squares method. The performance of the ANFIS classifier was evaluated in terms of training performance and classification accuracies and the results confirmed that the proposed ANFIS classifier has potential in detecting the tumors

Aerodynamics of a swirling fluidized bed

Swirling Fluidized Bed (SFB) is one of the fluidized bed systems that have potential to be widely used in the mineral processing, power generation and chemical industries. By using an annular bed and inclined injection of gas through the distributor in SFB it will archive a high performance in fluidization. A numerical simulation Computational Fluid Dynamics (CFD) and experimental work with Particle Image Velocimetry (PIV) has been used to investigate physical parameters that influence the type of plenum chamber, the distributor pressure drop and the uniformity of tangential velocity distribution. The study focused on the 60 blades distributor whereby the effect of two horizontal inclinations (12° and 15°) and tangential entry plenum chamber (single, double and triple). Three velocities component were analyzed; tangential velocity, radial velocity and axial velocity. In actual industrial applications, the axial velocity will create fluidization while the tangential velocity provides swirling effect. The presence of radial velocity can be explained as a consequence of centrifugal force generated by the swirling gas. The tangential velocity is the major velocity component in this study and it represents the velocity of the swirling air in the annular region of the bed. The uniformity of tangential velocity distribution and pressure drop is set as performance criteria and has been analyzed with statistical method; mean value, standard deviation & root mean square of difference (RMSD). The most significant finding in simulation configuration is the pressure drop of the distributor blade increased when a triple tangential entry plenum chamber along with horizontal inclination 15° has been applied which then create high tangential velocity. Only parameter for double tangential entry plenum chamber consists with horizontal inclination, 12° has been selected to validate with the PIV result. Comparison of the simulation result (CFD) and experimental data (PIV) are presented, and it is confirmed that good agreement is obtained
