An Experimental Study on Low-Calcium Flyash and Metakaolin Based Geo-Polymer Concrete

Geo-polymer concrete is known as one of environmental- friendly construction materials. Using by-product material such as flyash and metakaolin replace cement would avoid carbon dioxide CO2 emission during the manufacturing process of ordinary Portland cement OPC . The objective of his research work was to produce a carbon dioxide emission free cementious material. This paper discusses low-calcium Flyash and metakaolin based geo-polymer concrete with different proportion of binder and molarities. 

The alkaline liquids used in this study for the polymerization are the solutions of Sodium hydroxide NaOH and sodium silicate Na2Sio3 . In this paper variation of source material for low-calcium Fly ash and Metakaoline and at various molarities like 10M, 12M and 14M is done to achieve compressive strength for medium grade of concrete of M-25. They are curing by oven at 600C for 24 hours then after ambient temperature. It is found that geo-polymer concrete with Metakoline and low-calcium Fly ash as increase its strength and shows good strength with increase in the molarity of the alkaline solution also comparable with that of Ordinary portland cement concrete.

Identifying the Slider-Crank Mechanism System by the MPSO Method

This paper mainly proposes an efficient modified particle swarm optimization MPSO method, to identify a slider-crank mechanism driven by a field-oriented PM synchronous motor, dynamic formulations of a slider-crank mechanism have been successfully formulated with only one independent variable. The parameters of many industrial machines are difficult to obtain if these machines cannot be taken apart. In system identification, we adopt the MPSO method to find parameters of the slider-crank mechanism. This new algorithm is added with "distance" term in the traditional PSO's fitness function to avoid converging to a local optimum. 

It is found that the MPSO method can obtain optimal high-quality solution, high calculation efficiency, and its feasibility and effectiveness. Finally, the comparisons of numerical simulations and experimental results prove that the MPSO identification method for the slider-crank mechanism is feasible.

Condition Monitoring of Wear Progress in Hydrostatic Pumps

This paper represents a practical methodology for monitoring the wear in the displacement elements in hydrostatic pumps. The technique is based on appropriate signal processing of the output pressure wave which reflects the geometrical changes in the internal parts. The geometry deviates in case of wear and the degree of deviation can be spatially analyzed to gain an indicator to the wear progress. The method is effective and computationally efficient in comparison to other algorithms, for ex. wavelet transformation. The design is followed by a successful experimental validation, for a case of internal gear pump IGP.

Homogeneous Swarm Robots Exploration

Exploration process in a real application seems had attracts the interest from researchers and academics nowadays. The usage of robots rather than human themselves give many benefit in term of security and safety, also in time and energy consumption. This project aims to generate a code represent the exploration technique in an unknown environment for homogeneous multi-agents systems. In multi-agents system, there are many variable involve in the result of the exploration process. 

The number of the agents, network connectivity, type of hardware, the environment and other aspects must be considered in multi-agents system exploration investigation. However, due to time constraint, this project only studies the effect of the number of robots or agents in the exploration task. The technique chose for the task must have a certain rules and assumptions to make the exploration process run smoothly and efficient. 

The code has been developed by using NetLogo due to the availability of sample models and toolboxes. Recording of the data was also done through the use of NetLogo. Finally, the data is arranged by using Microsoft Excel to extract the recorded data for analysis process. The usage of Minitab software is used to plot the graph. Hopefully, this system can be used in real application with the appropriate hardware.

Investigation on the Existing Geometry of Pathein Suspension Bridge

Pathein Suspension Bridge constructed across Pathein River completed in 2004 is a single-span suspension bridge. The region has soft alluvial ground. According to 2012 bridge inspection report, Current Situation and Issues of Myanmars Bridge Work, this suspension bridge had lost a great deal of camber since completion. And also it is found that there are some problems such as movement of anchor block, tilting tower. In this study, investigations on the existing of Pathein suspension bridge are presented by using 3D laser scanner, and site surveying. 

According to the investigation results, it is found that all towers are inclined towards river and the maximum inclination occurs the downstream tower of Chaungthar side. The downstream main cable sag is lower than the upstream one. Most hangers are inclined towards Pathein side and the maximum inclination degree occurs at middle portion. The existing truss profile is very different from as per drawing and all truss nodes are under the horizontal surface. Therefore seismic risk assessment and disaster mitigation plan for unexpected future severe earthquake should be developed.

Inter-Cell Interference

The continuously increasing demand for higher data rates results in increasing network density, so that inter-cell interference is becoming the most serious obstacle towards spectral efficiency. Considering that radio resources are limited and expensive, new techniques are required for the next generation of cellular networks, to enable a more efficient way to allocate and use radio resources. In this framework, we target the design of a frequency reuse 1 scheme, which exploits the coordination between base stations as a tool to mitigate inter-cell interference.
