41.An Improved Brain Storm Optimization with Differential Evolution Strategy for Applications of ANNs

Author:Cao, ZJ;Hei, XH;Wang, L;Shi, YH;Rong, XF

Source:MATHEMATICAL PROBLEMS IN ENGINEERING,2015,Vol.2015

Abstract:Brain Storm Optimization (BSO) algorithm is a swarm intelligence algorithm inspired by human being's behavior of brainstorming. The performance of BSO is maintained by the creating process of ideas, but when it cannot find a better solution for some successive iterations, the result will be so inefficient that the population might be trapped into local optima. In this paper, we propose an improved BSO algorithm with differential evolution strategy and new step size method. Firstly, differential evolution strategy is incorporated into the creating operator of ideas to allow BSO jump out of stagnation, owing to its strong searching ability. Secondly, we introduce a new step size control method that can better balance exploration and exploitation at different searching generations. Finally, the proposed algorithm is first tested on 14 benchmark functions of CEC 2005 and then is applied to train artificial neural networks. Comparative experimental results illustrate that the proposed algorithm performs significantly better than the original BSO.

Source:ENVIRONMENTAL ARSENIC IN A CHANGING WORLD (AS2018),2018,Vol.

Abstract:In paddy soil the reductive dissolution of iron oxide and the availability of organic matter plays an important role in arsenic release under anaerobic conditions. Microbial fuel cells have been shown to reduce organic matter (OM) content and the rate in which this occurs strongly relate to the external resistance applied. In this study we investigated the effects of bioanode operating at different external resistance on the paddy soil microbial community and iron and arsenic concentration. The results show that MFC can be used to reduce soil pore water iron and arsenic concentration and the extent in which this occurs depend on the external resistance applied. The MFC is able to mitigate arsenic release by decreasing organic matter availability. Furthermore, our finding shows that external resistance had a significant influence on the bacterial community composition that develop on the bioanode however only had minimal effect on the community of the bulk soil. These findings suggest that the sMFC can influence the iron and arsenic concentration by reducing OM content and the microbial community that develop in the bioanode vicinity.

Abstract:Recycled aggregates have been widely studied and used in concrete products nowadays. There are still many waste materials that can be used as recycled aggregates other than crushed concrete particles. This paper aims to study the property variations of sustainable concrete paving block incorporating different contents of construction wastes. Five different types of waste materials were used in this project, including: recycled concrete coarse aggregate (RCCA), recycled concrete fine aggregate (RCFA), crushed glass (CG), crumb rubber (CB), and ground granulated blast furnace slag (GGBS). According to the test results of the properties of blocks mixed with different levels of wastes materials, it is concluded that adding both RCCA and RCFA in the block can decrease its strength and increase the water absorption. The suggested replacement levels for RCCA and RCFA are 60%% and 20%%, respectively. Mixing crushed glass in the concrete paving blocks as a type of coarse aggregates can improve the blocks' strength and decrease the blocks' water absorption. Addition of crumb rubber causes a significant deterioration of blocks' properties except for its slip resistance.

Abstract:Due to high flexibility, reliability, and strong actuation forces, piezo fiber based composite smart material, macro-fiber composite (MFC), is increasingly applied in various fields for vibration suppression, shape control, and health monitoring. The complexity arrangement of MFC materials makes them difficult in numerical simulations. This paper develops a linear electro-mechanically coupled finite element (FE) model for composite laminated thin-walled smart structures bonded with MFC patches considering arbitrary piezo fiber orientation. Two types of MFCs are considered, namely, MFC-d31 in which the d(31) effect dominates the actuation forces, and MFC-d33 which mainly uses the d(33) effect. The proposed FE model is validated by static analysis of an MFC bonded smart plate.

Abstract:Key issues of indoor localization is taking full advantages and overcoming its disadvantages. indoor localization based on Wi-Fi fingerprinting attracts researchers' attentions since it does not require new infrastructure and devices. Many devices such as smart phones and laptops, which have a function to capture Wi-Fi signals, can be used for Wi-Fi fingerprinting. However, due to unreliable Wi-Fi signals, there are still difficulty to achieve high positioning accuracy. The unreliable signal disturbs devices to find their locations. As a result, getting localization with devices sometimes makes a wrong decision in building classification. It is useless for people to find a destination floor if they are in different building. In this paper, we propose two consecutive multi-layer perceptrons to get more precise localization. With sumple structure, we get better performance and show precise decision results in building classification, which is critical in Wi-Fi fingerprinting. We use UJIndoorLoc dataset which is open dataset.

Abstract:Technologies are continuously evolving and transportation agencies are always trying to find appropriate technologies to assist with their projects. However, it might be hard to answer what technologies and tools are appropriate for them to use and when to use those technologies and tools. Thus, the purpose of this study is to investigate leading transportation agencies' uses of various advanced technologies (e.g. geographic information system (GIS), light detecting and ranging (LiDAR), 3D engineered models, automatic machine guidance (AMG), mobile devices, intelligent compaction (IC), and electronic document management (EDM) system). Based on the 2 weeks of on-site visits to seven transportation agencies, benefits and lessons learned of using these technologies are summarized in the paper. Additionally, a framework is developed to suggest the proper occasions to use various technologies and manage the resulting data throughout the lifecycle of a transportation project.

53.Macroinvertebrate drift-benthos trends in a regulated river

Author:Tonkin, JD;Death, RG

Source:FUNDAMENTAL AND APPLIED LIMNOLOGY,2013,Vol.182

Abstract:Downstream drift plays a fundamental role in the spatial distribution and community structure of lotic macroinvertebrates. We sampled both benthic and drifting macroinvertebrates at 15 sites, in three sections of river with varying flow alteration along the Tongariro River, New Zealand. Our objectives were to examine whether (i) benthic and drift density were linearly related throughout the river, (ii) the presence of dams affected the propensity of macroinvertebrates to drift, and (iii) drift propensity was related to benthic periphyton biomass or natural longitudinal patterns down the river. More taxa were collected from the drift than the benthos, although drift and benthic samples were generally taxonomically similar, despite some structural differences. Nonetheless, differences were evident between the major groups when assessing density and relative abundance links between the benthos and drift. The presence of dams did not affect the propensity of macroinvertebrates to drift on the whole, nor was propensity affected by periphyton biomass or distance from source. These results suggest that although altered periphyton biomass in downstream sections in the Tongariro River is altering the composition of benthic and drifting macroinvertebrates, drift propensity is unaffected. However, some deviations from linear relationships between benthic and drift density are evident suggesting these links may be taxon specific.

Source:Journal of Power Supply,2019,Vol.17

Abstract:To achieve a higher power conversion efficiency, a cascode structure based on 650 V gallium nitride high electron mobility transistor(GaN HEMT) was introduced, together with its applications in wireless power transmission. From the aspect of GaN HEMT design, the effects of field plate design on capacitance and electric field were discussed through simulations. The fabricated cascode device had a leakage current of 2 muA at drain-source voltage of 650 V. At 400 V, the input capacitance C_(iss), the output capacitance C_(oss) and the reverse transfer capacitance Crss were 1 500 pF, 32 pF and 12 pF, respectively, and the dynamic on-resistance increased by about 16%%. Based on the design of this cascode device, a wireless charging prototype with operation frequency of 240~320 kHz and full-load power of 1 kW was designed and presented. Compared with the equivalent Si device, its efficiency was obviously higher within the load range of 200~1 000 W, with the peak efficiency higher than 95%%.

Abstract:Objective: To propose a fast and reliable method for the determination of intracellular lipid accumulation. Method: Lipid accumulation in HepG2 cells were induced by oleic acid. Lipid droplets were stained with BODIPY 493/503 and measured with fluorescent image processing using Matlab or ImageJ. The images results were compared to those of Adipophilin,a widely served marker for lipid accumulation,which were determined from protein and mRNA levels by Western blotting and qPCR. Result: By processing fluorescent images using BODIPY 493/503 staining for lipid droplets and comparing data outputs with Matlab and ImageJ, a method using Matlab as image processing platform was established for the determination of intracellular lipid accumulation ; a 1. 41 - fold increase in oleic acid - induced lipid accumulation was detected by fluorescent image processing, which were in accordance with the markedly enhancement in Adipophilin protein levels (2. 07 - fold) and mRNA levels (1. 53 - fold). Conclusion: The method combining fluorescent staining and image processing shall help analyze the intracellular lipid accumulation both rapidly and accurately.

56.HOW THE 1978 FOREIGN DOMESTIC WORKERS LAW INCREASED THE LABOR SUPPLY OF SINGAPOREAN WOMEN

Author:Freire, T

Source:SINGAPORE ECONOMIC REVIEW,2016,Vol.61

Abstract:In 1978, Singapore became the first country to introduce legislation allowing foreign domestic workers to work in the country under special visas. Although Singapore is often cited in the literature as a success story, no studies have quantified the impact of this legislation. In this paper, we use data derived from the Singapore Yearbook of Manpower Statistics between 1974 and 1985 to determine the influence of the 1978 legislation on the labor supply of Singaporean women. We find that the labor supply of women affected by this policy increased by between 3.1%% and 6.2%%.

57.A novel cluster HAR-type model for forecasting realized volatility

Author:Yao, XZ;Izzeldin, M;Li, ZX

Source:INTERNATIONAL JOURNAL OF FORECASTING,2019,Vol.35

Abstract:This paper proposes a cluster HAR-type model that adopts the hierarchical clustering technique to form the cascade of heterogeneous volatility components. In contrast to the conventional HAR-type models, the proposed cluster models are based on the relevant lagged volatilities selected by the cluster group Lasso. Our simulation evidence suggests that the cluster group Lasso dominates other alternatives in terms of variable screening and that the cluster HAR serves as the top performer in forecasting the future realized volatility. The forecasting superiority of the cluster models are also demonstrated in an empirical application where the highest forecasting accuracy tends to be achieved by separating the jumps from the continuous sample path volatility process.

Source:Matters,2019,Vol.

Abstract:Many infectious diseases lack cheap, fast, and reliable serodiagnostic tools. Recently, glycans coupled to gold nanoparticles (GNPs) have shown potential to fill this void by utilizing them as a coating in ELISA experiments. In this study, we used GNPs functionalized either with galactofuranose (Galf), rhamnose (Rhap) or a mixture of these monosaccharides to detect the presence of IgM and IgG antibodies against these non-human carbohydrates in sera obtained from tuberculosis patients and control groups. Our findings confirm the wide abundance of anti-Rhap antibodies in humans and show for the first time the presence of anti-Galf antibodies in human sera. This study supports further investigation of using GNP-ELISA with microbe-specific carbohydrates for serodiagnosis of infectious diseases.

Source:MONTHLY NOTICES OF THE ROYAL ASTRONOMICAL SOCIETY,2021,Vol.506

Abstract:Recent observations of young embedded clumpy clusters and statistical identifications of binary star clusters have provided new insights into the formation process and subsequent dynamical evolution of star clusters. The early dynamical evolution of clumpy stellar structures provides the conditions for the origin of binary star clusters. Here, we carry out N-body simulations in order to investigate the formation of binary star clusters in the MilkyWay and in the Large Magellanic Cloud (LMC). We find that binary star clusters can form from stellar aggregates with a variety of initial conditions. For a given initial virial ratio, a higher degree of initial substructure results in a higher fraction of binary star clusters. The number of binary star clusters decreases over time due to merging or dissolution of the binary system. Typically, similar to 45 per cent of the aggregates evolve into binary/multiple clusters within t = 20 Myr in the Milky Way environment, while merely similar to 30 per cent survives beyond t = 50 Myr, with separations <= 50 pc. On the other hand, in the LMC, similar to 90 per cent of the binary/multiple clusters survive beyond t = 20 Myr and the fraction decreases to similar to 80 per cent at t = 50 Myr, with separations less than or similar to 35 pc. Multiple clusters are also rapidly formed for highly substructured and expanding clusters. The additional components tend to detach and the remaining binary star cluster merges. The merging process can produce fast rotating star clusters with mostly flat rotation curves that speed up in the outskirts.
