Gold is found in part by the thousands in rocks, which makes it necessary to mine a large quantity of rock in order to obtain a minimum quantity of gold. This leads to the generation of a significant amount of solid waste product because of the crushing and grinding of the material that generates waste from block size to sandy and fine granulometry. These residues end up as deposits on the surface or slopes that generate the danger of landslides or damage in the soil, another large part of the ground material ends up dumped in rivers and streams, which increases the rate of sedimentation and the deposition of heavy metals. In Colombia, the areas that are dedicated to the exploitation of gold encompass large regions, which generates that a significant amount of water sources are affected, in addition, the mines are in some cases close to the paramos such as the Santurban paramo, an important source of water in the north of Colombia. In the field studies, it was observed that 6 tons of sterile waste is generated per day that meets the standards as a construction aggregate for use in the concrete mix. In the tests carried out it was found that it can be used for structural concrete. Petrographic and chemical analyzes revealed significant silica content from plagioclase, quartz, and micas that make up the sterile residue.

A numerical lock-in prediction technique of a NACA 0012 hydrofoil, immersed in a flow having a Re of 3.07x106 is proposed in this paper. The technique observes the foil’s response as part of a fluid-structure interaction analysis. The response is modelled by foil’s vibration which is represented by spring and damper components. The technique identifies and predicts the foil’s lock-in when it vibrates. The prediction is examined using the Phase Averaged Method which employs the Hilbert Transform Method. The aim of this paper is to propose a numerical way to identify a lock-in condition experienced by a NACA 0012 foil in a high Reynolds number flow. The foil’s mechanical properties are selected and its motions are restricted in two modes which are in the pitch and heave directions. The rotational and transverse lock-in modes are identified in the model. The existence of lock-in is verified using pressure distribution plot, the history of trailing edge displacement and fluid regime capture. The history of total force coefficients is also shown to justify the result. The result shows that the technique can predict reliably the lock-in condition on the foil’s interaction. Three main fluid induced vibration frequencies are generated in the interaction. None of them are close to natural frequency of the foil and lock-in is apparently not found in the typical operational condition.

Solar air heater (SAH) is a renewable energy application for the drying process. SAH has a challenge to produce high performance under uncertain weather. The performance of SAH can be enhanced by providing the absorber plate by adding the fins. This study aims to evaluate the thermal performance of SAH with rectangular fins SAH at low air velocity. This study compares the performance of SAH without fins and SAH with rectangular fins. Two variations of a tilt angle of SAH are 0° and 30° which are observed in this study. The SAH uses a ventilator turbine to suck air into the collector box. The air velocity is 0.01 m/s. The method is experimental. The SAH is tested under real condition from 9 a.m. to 4 p.m. The measurement tools consist of a pyranometer, an anemometer, a temperature sensor in the inlet section, 3 sensors in the absorber plate, a sensor in the outlet section, 6 temperature sensors in the drying cabinet. The result showed the thermal efficiency of SAH with rectangular fins is 29.67 % higher than SAH without fins at 0 ̊ tilt of angle at noon. The thermal efficiency of SAH with rectangular fins is 25.26 % higher than that of without fins at 30 ̊ tilt of angle at noon.

This paper presents an analysis of the affected area at an ocean disposal site, in terms of sediment dispersion, as a consequence of the dis-posal of dredged material from the approach channel for Buenaventura´s Port. The analysis was carried out at three points within Buenaven-tura´s Bay, one located at the authorized disposal site, a second point at a proposed future disposal site and a third point at the Bocana Sector, where the highest tidal velocities are identified. The PTM (Particle Tracking Model) mathematical model was used for this investigation, showing that due to the hydrodynamic conditions, a sediment particle can reach a longer dispersion distance from its original disposal point. Finally, sediment dispersion at the three analysis points were compared in terms of current velocity and maximum displacement.

Locomotion of humanoid robot depends on the mechanical characteristic of the robot. Walking on descending stairs with integrated control systems for the humanoid robot is proposed. The analysis of trajectory for descending stairs is calculated by the constrains of step length stair using fuzzy algorithm. The established humanoid robot on dynamically balance on this matter of zero moment point has been pretended to be consisting of single support phase and double support phase. Walking transition from single support phase to double support phase is needed for a smooth transition cycle. To accomplish the problem, integrated motion and controller are divided into two conditions: motion working on offline planning and controller working online walking gait generation. To solve the defect during locomotion of the humanoid robot, it is directly controlled by the fuzzy logic controller. This paper verified the simulation and the experiment for descending stair of KMEI humanoid robot.

Wireless body area networks (WBANs) are emerging as important networks that are applicable in various fields. WBAN gives its users access to body sensor data and resources anywhere in the world with the help of the internet. These sensors offer promising applications in areas such as real-time health monitoring, interactive gaming, and consumer electronics. WBAN does not force the patient to stay in the hospital which saves a lot of physical movement. This paper reviews a review of WBANs. We study the following: prior researches, applications and architectures of WBAN, and compression sensing techniques.

Subsea separation is an attractive and economical solution for the development of deepsea offshore oil and gas fields that generate hydrate or wax-free fluids. The submarine separation system must be able to ensure successful operation over a wide range of multiphase flows. Subsea separators can be an efficient tool to improve hydrocarbon production and avoid or simplify the expensive surface platforms of floating vessels. One of the solutions of interest is separating and reinjecting water from the seabed so that water does not go up to the surface facility. In this study, the liquid-liquid flow characteristics inside the inline subsea separation system were investigated for the design of the subsea separation system. The separation efficiency of the submarine separator is determined through a liquid-liquid phase separation phosphorus experiment. In addition, the internal vortex element (ISE) modeling of the separator has been optimized. The results of the analysis were utilized to improve the reliability and efficiency of the subsea separation system.

Electricity Generating Authority of Thailand is the largest power producer in Thailand, owning and operating power plants at 45 sites across the country. With forthcoming global climate crisis, current effort in improving energy efficiency and adopting alternative sources of energy may not be sufficiently rapid. Post-combustion carbon capture with amine based solutions is a well-established technology and offers a further option in reducing carbon dioxide emissions from existing power plants. In this work, a laboratory-scale, amine based CO2 absorption setup was developed and its performance test was carried out, using Monoethanolamine at 30% concentration handling flue gas conditions similar to those from Mae Moh power plant. The preliminary results revealed high carbon capture efficiency (>97%) could be achieved in a continuous operation.
