Published: November 2019

With the wide use of the global navigation satellite system (GNSS), its vulnerability has become an increasing serious problem. More specifically, interference is one of the severe challenges faced by GNSS applications. There are relatively mature detection and excision methods for the simple interference currently, such as pulse interference, single-tone interference, and narrow-band interference. On contrary, for complicating interference, such as fast chirp interference, there are a few effective suppression methods. In this paper, the model of periodic fast chirp signal is built first. Then, several traditional interference suppression methods of GNSS receiver are used to excise fast chirp interference to analyse their feasibility. Finally, both theoretical analysis and simulation results show that traditional interference suppression methods for the GNSS receiver do not perform well on fast chirp interference.

Published: November 2019

In order to solve the defects in welding seams of submerged arc welding, the X-ray images were used to detect defects. By comprehensive analysis and experimental study, the offline database of defects in welding seams was established, and online intensification and segmentation algorithm as well as recognition method based on the compressed sensing for defect images were designed. First, the defect database of X-ray images of welding seams was established by the offline data. After the welding images were acquired, the defect segmentation and acquisition algorithm based on the clustering method were proposed. A series of characteristic values of defects in the offline database were used as atoms in the compressed sensing algorithm dictionary, and atoms were optimized with the PCA method, to facilitate the improvement of the processing speed. Supported by the optimal dictionary, the category of defects was obtained. The actual analysis of circular and linear defects was carried out to give ROC curves classified in two cases.

Published: November 2019

With the occurrence of terrorist attacks in tourist attractions, safe and efficient population evacuation scheme becomes very important. Effective evacuation plan can reduce casualties and economic losses, and more reasonable and scientific evacuation plan is of great significance. At present, most of the existing evacuation algorithms are for Single-storey buildings. Even for multi-storey buildings, they can not take into account the types of tourists and some additional interference factors in evacuation, and can not accurately estimate the shortest evacuation time needed, and can not be widely applied to various buildings. To solve these problems, an adaptive ant colony model based on CCRP optimization algorithm is proposed to help Louvre visitors escape from danger effectively in terrorist attacks. In this paper, the shortest escape time is accurately predicted, and the simulation results are basically consistent with the results of the model. Finally, three landmark buildings, Elements Museum in Austria, Student Apartment in Switzerland and Wal-Mart, are solved, which further illustrates the validity and universality of the model.

Authors: Zhu Jiang , Hosaka Yurio , Yoshioka Hayato
Published: November 2019

Self-intersection is a serious problem in computational geometry and digital manufacturing. Because intersected parts do not exist in the physical world, the self-intersection must be removed for actually applications such as 3D printing or CNC machining. In the conventional method, such intersected parts are usually deleted, which causes the change of the original shape. In this research, a robust algorithm to remove the self-intersection of 3D mesh model is proposed. It could automatically detect the self-intersection, and remove the self-intersection without changing the original shape. The proposed algorithm has four steps. (1) Detect the intersected facets in the mesh model. (2) Divide the intersected facets along the crossing lines. (3) Find the outside facets. (4) Delete the inner facets and burying facets. Different models are used to do experiments, and the experimental results prove the validity and practicability of the proposed algorithm.

Published: November 2019

Video object segmentation is a mainstream branch of current image processing direction. How to achieve deep learning from complete supervision to unsupervised is the key problem that people are trying to solve. In this process, One-Shot Video Object Segmentation (OSVOS) can successfully tackle the task of semi-supervised video object segmentation. It transfers the general semantic information learned on ImageNet to the foreground segmentation task, and then learns the mapping of a single annotated object in sequence. In this paper, based on the concept of OSVOS, an improved neural network structure with dilated convolution, multi-scale convolution fusion and skip layer is proposed. Dilated convolution can increase the size of the receiving field. Multi-scale convolution can obtain multi-scale feature maps and fuse them. Skip layers can transfer feature information from low layer to upper layer. All of them help to improve the final accuracy. The experimental results show that all indicators has been improved.

Published: November 2019

Giant atter species (Gigantochloa atter (Hassk) Kurz) is one of the non-timber forest products that is currently widely used by the community in various needs, including: conservation plants, buffer zone plants, home building construction materials, and for handicraft materials. However, the large number of uses of this bamboo as raw material is not balanced with efforts to preserve and develop it through cultivation, causing the giant atter declining in nature. Therefore, the multiplication technique using branch cuttings is one of the important choices for mass development of the bamboo in the future. This study aims to determine the effect of the position of branch cuttings on bamboo stems and the concentration of hormones that can provide the best growth in the field. The treatment consists of two factors as follows: the first factor is the position of branch cuttings on the stem, namely: the base, the middle part, and the tip of the bamboo stem. The branch cuttings were lubricated with growtone hormone with a dose variation of 15 mg, 30 mg, 45 mg, and 60 mg for each branch cuttings. The results showed that the development of giant atter in a large quantities, branch cuttings can be used from all parts of the bamboo stem as plant material, and a dose of growtone hormone as much as 30 mg gives a good ability to grow in the field. The impact of this study is expected to be a guideline for policy makers in the Department of Forestry in the context of mass development of bamboo through vegetative cultivation.

Published: November 2019

Women play an important role in supporting the environment economics, especially in supporting the independence of the area around the forest through entrepreneurial activities. This study aims to analyze the relationship between social conflict and natural resources, especially in forest areas, and identify the role of women in conflict resolution management through the use of natural resources. Since women have the skills and knowledge in processing natural products, it has been utilized as a strategy to minimize social conflicts. Social conflict closely related to natural resources due to dissatisfaction from the community. Conflicts in forestry areas will persist as long as differences in interests among stakeholders still exists. For this reason, the role of women in processing natural products becomes essential. Even though the activity is one of the informal sector activities, it can support the family economy if conducted optimally. This study found that the role of government was insufficient in supporting entrepreneurial activities in remote areas, especially in forest areas. Research data showed that there are still many village women who do not have skills in processing natural products. The condition is a result of the lack of collaboration between the government and the private sectors.

Published: November 2019

Rice classified as susceptible to salinity, especially at the seedling stage. To improve the salinity tolerance, one of the methods used is through seed priming. This study aims to figure out the effect of seed priming with NaCl on the seedling of Banyuasin and IR 64 varieties growth under salinity stress (1.2 m/s). The research was conducted in the Laboratory of Plant Science, Faculty of Agriculture, Ehime University, Japan using an experiment with clustered randomized design pattern. There were eight package of treatment, including V1H0M0, V1H0M1, V1H1M0, V1H1M1, V2H0M0, V2H0M1, V2H1M0, and V2H1M1 (V1: IR 64 variety, V2: Banyuasin variety, H0: Seeds without priming, H1: Seeds with priming, M0: non-saline media. M1: saline media of 1.2 m/s). Each treatment was replicated three times resulting in 24 units of the experiment. The results showed that salinity suppressed seedling growth. Even though primed Banyuasin seeds showed the best results for the variables mean of plant height, root length, shoot biomass, root biomass, and plant biomass, (34.27 cm, 19.03 cm, 0.81 g, 0.18g, and 0.99 g) under salinity stress, these results were not statistically different from any other treatment under the same growth condition. We suspected that the salinity level of the media was too high so that even primed seeds are unable to overcome the stress. This study also showed that primed Banyuasin seeds growth under salinity stress can maintain the lowest Na+ions accumulation in the shoot (2.33 mg g-1), and these results were significantly different with any other treatment under the same condition. This data indicated that seed priming enhances plant ability to maintain lower Na+accumulation in a shoot, that is crucial to overcome salinity and to improve tolerance to salinity stress.

Nowadays, the research about the harvesting of renewable energy sources is more interesting on being able to do the conversion and conservation of thermal energy source, which is very abundant in our environment especially in form of waste heat. The abundance of waste heat energy in our daily life is needed to be converted to become something useful like electrical energy. The research about a material called metamaterial in the form of thermal concentrator has shown the capacity for focusing heat flux into a specific area. Optimized flower-shaped metamaterial thermal concentrator design is successful to concentrated the heat flux from any direction to specific area efficiently. This research is about numerical analysis of harvesting thermal energy to become DC electrical energy by using a design of metamaterial thermal concentrator, especially the design of optimized flower-shaped metamaterial concentrator by using the thermoelectric device. The result showed that with using optimized metamaterial thermal concentrator can increase the output voltage of thermoelectric device become 4,1 volt, compare than without using the concentrator that just gets output voltage 3,3 volt.

Mudskipper is a species of fish that mostly found in the estuaries and coastal areas with mud substrates. This fish can adapt to wet conditions and change temperatures by hiding in the holes around the mangrove. The purpose of this study was to identify the diversity of mudskipper fish according to the environmental conditions of estuarine in Merauke district. The study was conducted in April-June 2018, with two observation stations. These stations were based on the characteristic differences in the estuary waters of Merauke district. This study used purposive sampling method. Data analysis used an ecological index (diversity index, uniformity, and dominance). The results showed that the diversity index was a moderate category (1.5858-1.5845). The distribution of species and individuals were spread evenly in each community while the environmental parameters were temperature (23-300C), salinity (20-30 ppt), pH (7, 1-8,1), Do (1.55-2.16), BOD (0.42-0.89), BOT (11.14-29.39. The clay (muddy) substrates strongly supported mudskipper live in the estuary.

Protected forests are the foundation of water availability and soil health. Even so, many protected forest areas that should be preserved, in fact, damaged and changed land functions. The preservation of protected forests is the responsibility of all parties. From the field of education, the application of an environment-based curriculum is a way of educating future generations about the importance of preserving the environment. This research is a type of descriptive research that aims to illustrate the extent to which environmental education has been implemented in schools. Data obtained by filling out a questionnaire which was then analyzed in a descriptive manner. Data analysis showed that the percentage of implementation of environmental education was 65.21% in the ‘good’ category. Although the results obtained are right, the application of particular environmental subjects has not yet been carried out to the fullest, plants in the school garden have not all been equipped with types and Latin names, and the use of nature as a learning medium has not been maximized.
