Wellbore integrity during Carbon Dioxide (CO2) storage in deep aquifers is a major problem as the currently used well cement will lose its integrity at higher temperatures and eventually leads to CO2 leakage into the atmosphere. Researchers have conducted several studies in order to find a proper well cement material and have tested several types of geopolymers mixing fly ash and different type of cements with an alkaline solution curing in different temperatures. This paper presents a study on geopolymer composites made from fired siltstone, slag as well as alkaline liquid which were cured at temperatures ranging from 23°C to 80°C. Five different types of geopolymer were prepared with ratios of fired siltstone (to 700 oC) and slag as 0:100, 20:80, 30:70, 40:60 and 50:50, separately. After preparing samples with various proportions under different temperatures, the mechanical properties of them were compared. The experimental results reveal that optimum curing temperature range is 50 to 70°C and addition of higher proportion of slag would help geopolymer gain better performance on mechanical strength compared to other geopolymer materials.

Power transmission network is the most critical part of a power system due to its connectivity with generation and distribution stations. Though it is a riskier employment to carry out the routine inspections of the transmission lines manually, the task of inspection is imperative to the continuous operation of the power system. However, the new trend of transmission line inspection is based on extracted details of the lines by means of Remotely Operated Vehicles (ROVs) traversing through them. This paper proposes a method being tested by a prototype for traversing alone the transmission conductor, inspecting the line through real time video streaming, detecting faults and pinpointing them through Geo Tagging. Automated transmission line inspection and fault detection is proposed to carry out through image processing and sensory data acquisition. Radio Frequency (RF) technology is the main communication mechanism between the operator and the ROV. This technology will expand the remotely operating distance of the ROV. Furthermore, a mechanism was developed to enable the robot to cross over from one span to another in the transmission network which include suspension type insulators.

Recent advances in network science have encouraged researchers to adopt a topological perspective in network assessment. This represents a paradigm shift from traditional network analyses for which the primary focus was flows. In this paper, we present a comprehensive topological investigation of the Road Traffic Network (RTN) of the Western Regional Megapolis in Sri Lanka. We identify the critical nodes (intersections) and links (road sections) within the RTN based on various network theoretic metrics. In addition, we assess the topological robustness of the RTN based on sequential failure (both random and targeted based on connectivity) of the intersections in the system. Our findings could inform policymakers in prioritizing the scarce funds available for future infrastructure investments.

Village tanks have been used for irrigation purposes from a longer period of time and its behavior as a cascade system can be considered as an efficient methodology towards a sustainable water management system. Though it’s not vividly addressed in recent studies, some tanks are present in a cascade system with a mere intention of retaining water for the downstream tanks and, are being called as retention tanks. Nevertheless, in the present day, those are being used to fulfill human water needs instead of their initial use as retention tanks. Due to this reason, the overall working capacity of village tank cascade systems is being diminished. And in this case study, a methodology is proposed to identify retention tanks using five cascade systems in Walawe ganga river basin.

Determination of the grain size is usually done by microscopic techniques which require special sample preparations. Nondestructive evaluation of grain size becomes important when sample preparation is restricted such as on a finished product. Nondestructive evaluation of grain size could be done through ultrasonic attenuation measurements. However, in such instances the dimensions of the components need to be known. As such, this work focuses on determining the grain size nondestructively when the material thickness is unknown. Hence, this paper presents a method to determine the grain size of a metal through ultrasonic longitudinal wave velocity to shear wave velocity ratio.

The strength and load slip behaviour of bolted timber joints depends on such as embedment strength of timber, bending strength of the bolt and on the joint geometry. This paper discusses an experimental study in which bolt diameter and timber member thickness ratio between side member and middle member were varied in three member bolted joints of “Hora” (Dipterocarpus zeylanicus) timber species consisting of a single bolt. Specimens were tested in compression applied parallel to grain direction. Load slip curves were plotted and compared to obtain influence of geometry parameters on load slip behaviour. In most cases load per unit slip is greatly increased with increase in bolt diameter. It was also identified that load per unit slip did not change considerably with timber member thickness ratio. British Standards are widely used in Sri Lanka. These are based on empirical approaches developed on European softwoods. In Sri Lanka hardwoods are frequently used. Experimental values were compared with predicted values from BS 5268-Part 2:2002. Failure modes predicted from BS 5268-part 2: 2002, compared well with those observed experimentally. Up to the predicted permissible load, experimental and theoretical joint slip values are very similar; the difference was less than 1mm.

Fretting fatigue is a complex mechanical phenomenon which combines the fretting and fatigue. This is common in components in contact and undergoing in oscillatory motion at the same time. Experimental studies of fretting fatigue require applying millions of load cycles in predicting fatigue life which consumes immense amount of time and money. This paper focuses on assessing use of finite element models and analytical techniques for fretting fatigue crack propagation. An analytical method based on Paris law and finite element simulation method using extended finite element method (XFEM) were adopted for predictions. For the analytical method stress intensity factor of the crack tip was extracted using a finite element model based on Virtual Crack Closure Technique (VCCT).

Halide Perovskite materials play a prominent role in solar cell industry as they comprise with advanced photovoltaic properties. Research is mainly based on the objective of investigating basic fundamental properties of CH3NH3PbI3 using Viana Ab-Initio Simulation Package(VASP). Before go to the experimental data analysis we have simulated fundamental photovoltaic properties of Methyl Ammonium Lead Iodide using computational method. CH3NH3PbI3 perovskite undergoes a phase transition between orthorhombic, tetragonal and cubic around 165K and 327K. Then the most stable structures are tetragonal and cubic phases. Therefore, in this research we have focused to study the basic crystallographic orientations, Energy band gap variation, Density of states in P, S orbitals and effective mass values of cubic and tetragonal phases in Methyl Ammonium Lead Iodide. Basic Density Function (DFT) theories like Local-density approximation of Kohn-Sham theory, Exchange correlation functional are basically used for theoretical calculations in this computational study.

Urban Heat Island phenomenon and heat column formation effects are directly affected by the outdoor temperature of the building. This leads to high on-coil temperature at the outdoor unit of the air conditioners (ACs). As a result, energy consumption by the AC system increases and Coefficient of Performance decreases and eventually provides low AC capacities than the rated amounts by the manufacturer. In reality and very often, building designers and shop keepers decide the required AC capacity for a given space referring the already tabulated cooling load capacity per unit area without performing any cooling load calculation or considering the other factors that would affect to the AC load. When it comes to high rise buildings, their approximations are often incorrect and obtaining the required thermal comfort from low capacity machineries is impossible. In order to prevent under-estimation of the required AC load, this study investigated the temperature increment of the outdoor conditions due to UHI and heat column formation by conducting few case studies and with the support of the Computational Fluid Dynamics simulations. It was revealed that in high-rise buildings surrounding temperature generally increases by 1.0 – 1.7°C for a 10-story building and the cooling load requirement of 10th floor in a high-rise building increases by 9–10% with respect to the ground floor.

Decolourization of textile dye containing effluent is a very difficult and challenging task textile industries have to face. Biological dye decolourization techniques can be effectively used in textile effluent treatments as an environmental friendly solution for the pollution created by coloured effluents. During the current study, Reactive Red EXF dye decolourization potential of isolated bacterial strain, Proteus mirabilis was studied. Dye decolourisation was most effective under static conditions and reached 94% decolourization after 72 hours of incubation. Optimum dye decolourization was observed at pH 7–7.5 range and at 40 °C temperature.
