Published: July 2020

Abstract
Automated optical inspection (AOI) is getting popular in quality of control in manufacturing. There is a huge demand to install AOI systems in production lines seamlessly. Usually, a conveyor is used in a product line to carry work-pieces. Thus, it becomes difficult to inspect the quality of products by images when work-pieces are moving. This paper proposed a robotic AOI system which is able to track moving objects in a conveyor to take clear images. This system can be installed into production lines on the fly. To achieve this, the system estimates the pose of the coming work piece using a camera before the work-piece arrives the inspection spot, and adjust the poses of the inspection cameras to align with the work piece. Then, the robot moves along the conveyor at the same speed and the system requires the correct calculation of image Field of View (FOV). By doing this, the robotic AOI system can take clear images of the work piece. We validated the system on a Denso RC8-series industrial robot equipped with eye-in-hand cameras to capture clear images while the work-piece is moving. The results show that the proposed system is able to take clear images when the conveyor speed is up to 10cm/sec.

Abstract
Recent years have seen a growing concern over global warming, as well as environmental pollution and protection issues. Resource recycling helps the effective reduction of greenhouse gases and environmental pollution, and improves the quality of life for many people. This paper proposes a deep-learning object detection system for resource recycling. The resource recycling of the objects including paper cups, plastic bottles, and aluminum cans was conducted by artificial intelligence. Single shot multibox detector (SSD) and faster region-based convolutional neural network (Faster R-CNN) models were utilized for the training of the deep-learning object detection. With regard to data set images and training time, the accuracy, training steps, and loss function of the SSD and Faster R-CNN models were studied. The accuracy and loss characteristics of the deep-learning object detection system for resource recycling were demonstrated. The system exhibits good potential for the applications of resource recycling and environmental protection.
Influence of Fly Ash and Recycled AAC Waste for Replacement of Natural Sand in Manufacture of Autoclaved Aerated Concrete
Authors: Lam N N 
Published: July 2020

Abstract
Currently in Vietnam, the source of natural sand used in construction in general and in production of autoclaved aerated concrete (AAC) in particular is increasingly exhausting, so finding new sources of raw materials to replace natural sand has important role to ensure the maintenance of construction material production activities as well as towards sustainable construction development. Autoclaved aerated concrete (AAC) is one of the lightweight concretes that commonly used in construction. AAC is relatively light in weight, having lower thermal conductivity, higher heat resistance, lower shrinkage, and faster in construction process when compared to the conventional concretes. This paper aims to research, use and compare the use of recycled AAC waste and fly ash to replace natural sand in AAC concrete brick production factory. The new developed AAC was conducted by replacing sand with recycled AAC and fly ash in ratio of 0%, 5%, 10%, 15%, 20%, 30%, 40% and 60, 80 and 100%. Mechanical tests such as density, compressive strength have been carried out. Research results show that it is possible to take advantage of recycled AAC waste products with a maximum content of 5% and fly ash with a content of up to 100% to replace the natural sand in the manufacture of AAC bricks. In terms of economic and technical efficiency, the use of fly ash is more optimal, because it allows reducing the volumetric density, enhancing compressive strength and minimizing the grinding cost as well as contributing to environmental protection, aiming to sustainable construction.
A Study on Using Crushed Sand to Replace Natural Sand in High-Strength Self-compacting Concrete Towards Sustainable Development in Construction
Authors: Lam N N 
Published: July 2020

Abstract
In recent years, the use of natural sand to produce concrete has led to increased demand for sand quarrying, resulting in this valuable resource exhaustion. Therefore, there should be synchronous solutions to limit the use of resources that are gradually depleted, contributing to environmental protection. One of the solutions is to use crushed sand to replace natural sand as aggregate in concrete, especially the study of using crushed sand to make high-strength self-compacting concrete. Crushed sand is an aggregate of angular shape and surface roughness that hinders the self-compacting of the concrete mixtures. Combination with fine mineral admixtures will be a good solution to improve the rheological properties of the concrete, i.e. reducing the internal friction between the angular particles in the paste system, increasing the ability to “lubricate” the aggregate particles, thereby creating excellent workability and self-compacting ability for concrete with slump flow of 820 mm and flow time of 4.5s, the ability to flow through reinforcing steel meets the technical requirements of EFNARC and compressive strength at the age of 28 days reaches over 85MPa.

Published: July 2020

Abstract
The SnBi solder system are argued to be the possible replacement for the lead and hazardous SnPb solder alloy. The features that differs in this study from the other types of Sn58Bi/Cu is the low mass usage of 20g. This low mass serves as to preserve materials and reduce waste. Yet, the main objectives to provide substantial data in term key properties of melting temperature, hardness and contact area properties of this Sn58Bi solder. The melting point of the Sn58Bi solder alloy is 142.25°C, close to the eutectic temperature. The average Vickers hardness value produced by the Sn58Bi was 28.8Hv, considerably high and close to the SnPb. The spreading area of the Sn58Bi solder alloy on the Cu substrate was calculated to 14.85mm2, at the soldering temperature 230°C. These properties are based on 20g of SB that can be predicted to be quite standout, and at the same time provides less waste of materials. Insight discussions are elaborated in this paper.

Published: July 2020

AbstractThe different wood modification processes give the opportunity to improve the applicability of such wood materials, which due to their lower biological resistance and/or weather resistance and/or dimension stability have a limited application field. Beside several plantation grown species (e.g. poplars or black locust), there are some species that are not plantation grown but available in considerable quantities, but with low added value during their utilization. These species are mainly used for energy recovery, but they have also the potential for the utilization with higher added value (e.g. furniture, claddings, etc.). These hardwood species are Turkey oak (Quercus cerrisL.), hornbeam (Carpinus betulusL.) and tree-of-heaven (Ailanthus altissimaMill.). They have in general high density, strength values and surface hardness. By improving of the properties their application could be widened by substituting more valuable wood species. Different modification techniques were used for the improvement of the properties of these wood species, namely heat treatment and oil heat treatment. In this paper selected wood properties were investigated which are important by the specification of the application fields of the treated material.
Relationship between the Fixation Period and Some Mechanical Properties of Pleated Wood
Authors: Németh R , Báder M 
Published: July 2020

Abstract
Longitudinally compressed wood (or pleated wood) is much easier bendable compared to untreated wood, even to much smaller curves. Its properties make pleated wood both an economically and environmentally friendly product for performing curved wood products. As a result of longitudinal compression, modulus of elasticity and required bending stress highly decrease, while bendability coefficient increases threefold. The longitudinal compression is usually followed by the fixation process: the degree of compression is held constant for a certain amount of time to relax the internal stresses in the wood. Fixation strengthens the effects of the treatment and it is used by the industry, but unfortunately, there is very slight literary knowledge available in this topic. We try to fill this gap by using different times of fixation and bending tests. The first minute of fixation is the most effective, but for example fixation for more than 10 hours results in a maximum deflection during 4-point bending tests of 675%, in a decrease of modulus of elasticity to 18.6% and in a decrease in bending stress at 5 mm crosshead displacement to 29.3%, compared to untreated specimens. Finally, pleated wood can undergo significant plastic deformation before fracture.
Role of Electrical Conductivity on Salinity and Mineralization due to Groundwater Level Fluctuations in Kolkata City
Authors: John B , Das S 
Published: July 2020

Abstract
This paper attempts to explain the relationship between the falling Groundwater level and the rising electrical conductivity of the Kolkata Metropolitan City. The groundwater level of the city is on the fall, and if it further depreciates, then it will lead to the flow of toxic elements from the Dhapa areas leading to increased minerals and dissolved salts in the groundwater, rendering the groundwater unfit for consumption. It is seen that the salinity of the groundwater is on the rise in Kolkata. The salinity or the degree of dissolved salts was tested using electrical conductivity parameter. The water level and electrical conductivity data was collected from different Government organisation and the EC for post 2018 was collected through field measurement using a TLC metre. Maps were prepared using GIS techniques and both the parameters (groundwater level and electrical conductivity) were correlated. It shows a positive correlation between groundwater level and electrical conductivity and maximum fall in the level is seen in the northern part of the city. If artificial recharge is done in the trough areas then only the problem can be solved to a greater extent.
Experimental Analysis and Numerical Simulation of Hydraulic Jump
Authors: Nandi B , Das S , Mazumdar A 
Published: July 2020

Abstract
Saint Venant equations are numerically solved to simulate the formation of hydraulic jump in a rectangular channel having a small bed slope. The MacCormack’s scheme is used for the solution by applying specified initial and boundary conditions until a steady state flow is reached. The location of the hydraulic jump is determined as a part of these computations. The artificial viscosity technique should be used in the computations to dampen the superior oscillations near the steep gradient of the simulated hydraulic jump. Twenty laboratory experiments were carried out for verification of the numerical model. The upstream Froude number for these experiments ranged from 2.17 to 7.0 in three different bed slopes 0, 0.02174, 0.0475. The simulated hydraulic jump profiles using the MacCormack’s scheme shows a good agreement with the experimental data. An empirical equation was developed to determine the location of hydraulic jump using regression analysis based on simulated data. Software based on Computational Fluid Dynamics (CFD) was also used to simulate two of these experiments. The results obtained from CFD analysis matched fairly with the experimental results.

Abstract
Maize silage, in spite of its rising prize and technological problems of monoculture in Eastern Germany, is still the most popular substrate for biogas plants. However waste materials often generate income, because of the potential technological or ecological problems they cause. Such an approach seems to be more profitable even considering lower biogas yield of dose waste substrates. To compare these different scenarios energetic and economical assessment of waste fermentation processes such be conducted. In this paper, three different substrates will be evaluated to determine their suitability for agricultural biogas plant feedstock.The research was based on the modified German standards DIN and VDI, while chemical and physical analytical methods were based on the Polish Standard System. Economic analysis was performed using standard prices in the polish biogas market. The calculation was conducted for 500 kW installation. Based on the obtained results, it was proven that refood was characterized by the highest methane and biogas yield from the analyzed substrate group. Maize silage fermentation in the Polish condition is least profitable due to the approximately 50 % income reduction by the costs of obtaining silage. However due to the price received for treating waste materials, refood fermentation is the most economically feasible option.

Published: July 2020

Abstract
Black soldier fly larvae (BSFL) are known to convert organic wastes into useful biomass, of which the composition depends on the substrate. It is of interest whether feed protein can be sustainably obtained from waste materials by feeding them to BSFL. This study aimed to convert rice straw and duck manure into BSFL biomass for conversion of waste into animal feed. The growth parameters of BSFL fed with pure fermented rice straw, pure duck manure, and an equal parts mixture of the two as well as its nutritional composition was determined. The larvae’s efficiency to consume and convert the different substrates was also evaluated. Results showed that BSFL fed with duck manure had significantly higher average individual weight of 0.0619±0.004 g, followed by mixture of duck manure and rice straw (0.0614±0.001 g), while those fed solely with rice straw did not accumulate the same biomass (0.0415±0.002 g). Correlations were also made for mass-length, mass-width, and length-width. Mass-length connection was the most reliable correlation (r = 0.732). The harvested BSFL protein was the highest for those fed with rice straw at 34.62%. Feed conversion ratio ranging from 3.71 to 11.3 was achieved for the substrates used. The availability of the waste substrate in large quantities coupled with efficient biomass conversion makes BSFL a sustainable organic matter converter primarily useful as additive to animal feed.
