Published: October 2020

Over the past three decades, China has experienced rapid economic growth along with a rapid increase in urbanization and living standards, leading to a boom in infrastructure demand. A large part of China’s newly constructed infrastructure is through urban construction; thus, cities have become a major source of material consumption and carbon emissions. Understanding the relationship between material consumption, carbon emissions, and the economic growth of cities is key to ensuring that the construction of infrastructure satisfies the needs for both economic development and dematerialization. In this study, we first accounted for material consumption and the carbon emissions of infrastructure construction of 34 cities in Northeast China and characterized spatial and temporal changes from 2010–2017. The material use and carbon emissions of infrastructure construction declined by 34.6% and 30.2% during this period. Specifically, material consumption decreased from 305.2 million tonnes to 199.6 million tonnes, and carbon emissions decreased from 77.7 million tonnes to 54.3 million tonnes. Furthermore, we used a decoupling indicator to evaluate the decoupling of material consumption or carbon emissions from GDP in these cities. We found that most cities have achieved the absolute decoupling of material consumption and carbon emissions from GDP over the study period. Finally, we proposed several policy recommendations for promoting the sustainable development of the infrastructure of cities. To ensure that cities realize low-carbon urbanization, policymakers need to promote modular buildings and low-emission construction materials. This paper also serves as a practical reference for the improvement of relevant materials and carbon emissions management strategies for other developing regions.

Published: October 2020

The stability control of a soft rock roadway is a crucial problem for sustainable utilization of limited coal resources in deep mining practices. To solve it, the soft rock types and failure mechanism of −890 entrance surrounding rock have been analyzed, taking Daqiang Coal Mine of China as an engineering example. The analysis shows that the damage to the surrounding rock was characterized by asymmetry, large deformation, severe damage, and extended durations. The surrounding rock can be divided into high‐stress‐jointed‐strong expansion soft rock based on S‐M scanning and mineral analysis. Numerical simulation is used to reproduce the failure process of the original supporting system and analyze the deformation of the surrounding rock, range of plastic zone, and distribution of the stress field. The failure mechanism is thus defined for a deep soft rock roadway. Combined with the above studies, the deformation mechanics of the surrounding rock is summarized as type IABIIABIIIABC. The stability transformation mechanism of the surrounding rock is proposed, based on which the control principle of deformation stability of a surrounding rock is formed. According to the control principle, “high strength support controls the surrounding rock deformation. The large deformation of the flexible support system releases the accumulated energy to the surrounding rock, and long‐term deformation of the surrounding rock is controlled by high strength truss support.” Meanwhile, the constant‐resistance, rigid, and flexible coupling (CRRFC) support system is proposed. The numerical analysis demonstrated that the CRRFC support system can effectively reinforce the shallow surrounding rock and improve the bearing capacity. Simultaneously, the development of the surrounding rock malignant plastic zone is effectively controlled. The application results show that the large deformation of the roadway can be effectively controlled by the CRRFC support system, which provides applications for similar engineering.

Angioimmunoblastic T-cell lymphoma (AITL) is a rare hematologic malignancy recognized in the WHO 2016 classification as a clinical and histological entity. It is a very poorly described disease in Africa due to its rarity and diagnostic difficulties, particularly differential diagnosis with tuberculosis. Here, we report a 57-year-old man who presented with fever, weight loss, and lymphadenopathies. The diagnosis of tuberculosis was carried out based on lymph node fine needle aspiration showing the image of tuberculous adenitis and CT images in favor of necrotic lymphadenopathies. The presence of autoantibodies and the failure of tuberculosis treatment led us to perform a biopsy with immunostaining that confirmed pathological features of AITL. The patient was treated by CHOP-based chemotherapy, and complete remission was achieved. This case highlights the difficulty of recognizing AITL and the importance of considering other potential differential diagnoses of tuberculosis in the endemic region.
Parking Space Reservation Behavior of Car Travelers from the Perspective of Bounded Rationality: A Case Study of Nanchang City, China
Authors: Xue Yunqiang , Cheng Lin , Lin Ping , An Jing , Guan Hongzhi
Published: October 2020

For travelers who inevitably use motor vehicles, in the case of limited parking spaces, reserving parking spaces in destination in advance helps reduce the time and emissions of searching for parking spaces and alleviate road traffic pressure. From the perspective of bounded rationality, this paper comprehensively considers the impact of traveler’s personal attributes and behavioral characteristics on parking reservations. The data processing analysis shows that the traveler’s age, gender, monthly income, and other characteristics have a certain impact on the parking reservation choice behavior. Reservation price is the key factor affecting the parking reservation policy. Travelers show different value perceptions of the reserved price of parking spaces, and this process has been verified to be roughly the same as the prospect theoretical model. As the reference point for highest reservation price becomes larger, travelers tend to choose to pay less than the ideal reservation price and become more sensitive to losses. It can be found from the model functions and survey data that the ideal reserved parking space price in the survey area is 5 yuan per hour which equals the normal parking fee, and the ideal parking reservation time is less than 2 hours. The research results provide a basis for formulating reasonable parking reservation schemes and parking policies.

In this study, high-performance liquid chromatography (HPLC) and colorimeter were applied to evaluate the quality of different species and differently prepared slices of Zedoray Rhizome samples with the aid of chemometric tools. Fifty batches of Zedoray Rhizome samples from different species and forty-two batches of Zedoray Rhizome samples from differently prepared slices were collected. The quantitative method was developed using HPLC to simultaneously determine the contents of twelve chemical ingredients in Zedoray Rhizome. The colour parameters L, a, and b were measured by a colorimeter. Then, the collected data were analyzed by the principal component analysis and Pearson correlation analysis. The results showed that the proposed method was capable of accurately determining the contents of the twelve chemical ingredients and the colour parameters for the collected samples. There was a dramatic difference in the contents of the chemical ingredients and in the colour parameters among different species and differently prepared slices of Zedoray Rhizome samples. This study reveals that combining HPLC, colorimeter, and chemometric tools can provide a new approach to comprehensively evaluate the quality of Zedoray Rhizome samples.

Background: Most data about the trachea are collected during deep inspiration breath holding (DIBH) using multi-detector computed tomography (MDCT). Images of the physiological changes in the central airway are lacking. Objective: The aim of this study was to explore the physiological changes in the central airway on MDCT during DIBH and deep expiration breath holding (DEBH). Method: The data from 62 patients (38 men and 24 women) who underwent enhanced computed tomography in our hospital were collected. Patients were grouped according to sex and age (18–45, 46–60, and >61 years). Anteroposterior diameter (APD) and transverse diameter (TD) at 3 levels (cricoid, intrathoracic inlet, and 2 cm above the carina), tracheal length, bronchial length, and subcarina angle (SCA) were measured. Results: The average length of the trachea from the cricoid cartilage to the carina was 103.91 ± 10.37 mm at DEBH and 108.63 ± 11.31 mm at DIBH (p < 0.001). The APD of the trachea at the level of the cricoid, intrathoracic inlet, and 2 cm above the carina showed no differences between DEBH and DIBH. The TD of the trachea at the level of the cricoid, intrathoracic inlet, and 2 cm above the carina showed no differences between DEBH and DIBH. The average length of the right main bronchus during DEBH and DIBH was measured as 13.21 ± 3.60 and 13.24 ± 3.49 mm, respectively (p = 0.956). The average length of the left main bronchus at DEBH and DIBH was measured as 44.19 ± 5.50 and 44.27 ± 5.11 mm, respectively (p = 0.929). The average SCA was 81.74 ± 14.56 at DIBH, while it was 80.53 ± 14.38 at DEBH. The change in SCA between DIBH and DEBH showed no significant difference (p = 0.642). Conclusions: The APD at the level of the intrathoracic inlet is larger than that at the cricoid and 2 cm above the carina, while the TD is the opposite. These findings about the trachea and bronchus in our study may contribute to bronchoscopy examinations, tube applications, stent design, and stenting.

Published: October 2020

Particle swarm optimization (PSO) is one of the famous heuristic methods. However, this method may suffer to trap at local minima especially for multimodal problem. This paper proposes a modified particle swarm optimization with dynamic acceleration coefficients (ACPSO). To efficiently control the local search and convergence to the global optimum solution, dynamic acceleration coefficients are introduced to PSO. To improve the solution quality and robustness of PSO algorithm, a new best mutation method is proposed to enhance the diversity of particle swarm and avoid premature convergence. The effectiveness of ACPSO algorithm is tested on different benchmarks. Simulation results found that the proposed ACPSO algorithm has good solution quality and more robust than other methods reported in previous work.

Authors: Alamirew Tesfaye , Balaji V. , Gabbeye Nigus
Published: October 2020

Proportional–Integral–Derivative (PID) controllers are used in many of the Industries for various process control applications. PID controller yields a long settling time and overshoot which is not good for the process control applications. PID is not suitable for many of the complex process control applications. This research paper is about developing  a better type of controller, known as MPC (Model Predictive Control). The aim of the paper is to design MPC and PID for a pasteurization process. In this manuscript comparison of PID controller with MPC is made and the responses are presented. MPC is an advanced control strategy that uses the internal dynamic model of the process and a history of past control moves and a combination of many different technologies to predict the future plant output. The dynamics of the pasteurization process was estimated by using system identification from the experimental data. The quality of different model structures was checked using best fit with data validation, residual and stability analysis. Auto-regressive with exogenous input (ARX322) model was chosen as a model structure of the pasteurization process and fits about 80.37% with datavalidation. MPC and PID control strategies were designed using ARX322 model structure. The controller performance was compared based on settling time, percent of overshoot and stability analysis and the results are presented.

The dynamic circuits are supposed to offer superior speed and low power dissipation over static CMOS circuits. The domino logic circuits are used for high system performance but suffer from the precharge pulse degradation. This article provides different design topologies on the domino circuits to overcome the charge sharing and charge leakage with reference to the power dissipation and delay. The precharge keeper circuit has been proposed such that the keeper transistors also work as the precharge transistors to realize multiple output function. The performance improvement of the circuit’s analysis have been done for adders and logic gates using HSPICE tool. The proposed keeper techniques reveal lower power dissipation and lesser delay over the standard keeper circuit with less transistor count for different process variation.

Virtualization is a new revolutionary approach in networking industry, its make possible to build several virtual machine (VM) in one physical hardware. In virtualization practice, one VM might be connected to others, but not all of VM in one environment must be connected due the privacy and security issues. One of the solutions which can address this issue is tunneling protocol. Tunneling protocol is a layer-2-in-layer-3 protocol which can isolate tenant traffic in virtualize environment. This research conducted about the performance of VXLAN and NVGRE tunneling protocol which works on virtualize environment and aims to determine the perfomances of throughput, delay, jitter, and vCPU Usage using variable packet size in range of 128-1514 byte. From the the result, can be conclude that both of tunneling protocol can isolate the traffic between tenant. For the performance result, NVGRE has the highest value of throughput, 771,02 Mbps and the VXLAN got 753,62 Mbps. For the delay NVGRE got 2.24 ms and VXLAN got 2.29 ms. For the jitter, NVGRE has better rate value of 0.361 ms, than VXLAN value of 0.348 ms, and the vCPU usage performance, NVGRE has the highest performance too that value is 60.57%. So on overall performance NVGRE has the better performance than VXLAN.

Published: October 2020

Tool wear prediction plays a significant role in machining industry for proper planning and control machining parameters and optimization of cutting conditions. This paper aims to investigate the effect of tool path strategies that are contour-in and zigzag tool path strategies applied on tool wear during pocket milling process. The experiments were carried out on CNC vertical machining centre by involving PVD coated carbide inserts. Cutting speed, feed rate and depth of cut were set to vary. In an experiment with three factors at three levels, Response Surface Method (RSM) design of experiment with a standard called Central Composite Design (CCD) was employed. Results obtained indicate that tool wear increases significantly at higher range of feed per tooth compared to cutting speed and depth of cut. This result of this experimental work is then proven statistically by developing empirical model. The prediction model for the response variable of tool wear for contour-in strategy developed in this research shows a good agreement with experimental work.

Authors: Periyasamy C.
Published: October 2020

Drawback of losing high frequency components suffers the resolution enhancement. In this project, wavelet domain based image resolution enhancement technique using Dual Tree Complex Wavelet Transform (DT-CWT) is proposed for resolution enhancement of the satellite images. Input images are decomposed by using DT-CWT in this proposed enhancement technique. Inverse DT-CWT is used to generate a new resolution enhanced image from the interpolation of high-frequency sub band images and the input low-resolution image. Intermediate stage has been proposed for estimating the high frequency sub bands to achieve a sharper image. It has been tested on benchmark images from public database. Peak Signal-To-Noise Ratio (PSNR) and visual results show the dominance of the proposed technique over the predictable and state-of-art image resolution enhancement techniques.

Published: October 2020

In this paper, a hybrid of Bat-Inspired Algorithm (BA) and Genetic Algorithm (GA) is proposed to solve N-queens problem. The proposed algorithm executes the behavior of microbats with changing pulse rates of emissions and loudness to final all the possible solutions in the initialization and moving phases. This dataset applied two metaheuristic algorithms (BA and GA) and the hybrid to solve N-queens problem by finding all the possible solutions in the instance with the input sizes of area 8*8, 20*20, 50*50, 100*100 and 500*500 on a chessboard. To find the optimal solution, consistently, ten run have been set with 100 iterations for all the input sizes. The hybrid algorithm obtained substantially better results than BA and GA because both algorithms were inferior in discovering the optimal solutions than the proposed randomization method. It also has been discovered that BA outperformed GA because it requires a reduced amount of steps in determining the solutions.

Published: October 2020

Deprivation indices are similar to inequalities index or index of disadvantageous. It was built to measure the basic necessities in a specific study area or region. There were many indices that have been constructed in the previous study. However, since these indices had depended mostly on two factors; socio-economic conditions and geography of the study area, thus different result would be generated in different areas. The objective of this study is to construct the new index based on above factors in Peninsular Malaysia by using a fuzzy logic approach. This study employed twelve variables from different facilities condition that was obtained from Malaysia 2000’s census report. These variables were considered as input parameters in the fuzzy logic system. Data turned into linguistic variables and shaped into rules in the form of IF-ELSE conditions. After that, the centroid of area method is applied to acquire the final deprivation index for a specific district in Peninsular Malaysia. The result showed that less developed states generated lower index for examples Kelantan and Kedah while more developed states generated a higher index for examples Selangor and W.P. Kuala Lumpur.

Published: October 2020

Python is a dynamic object-oriented programming language. Python provides strong support for integration with other programming languages and other tools. Python programming is rarely used in the field of artificial intelligence, especially artificial neural networks. This research focuses on running Python programming to recognize hiragana letters. In learning the character of Hiragana, one can experience difficulties because of the many combinations of vowels that form new letters by different means of reading and meaning. Discrete Hopfield network is a fully connected, that every unit is attached to every other unit. This network has asymmetrical weights. At Hopfield Network, each unit has no relationship with itself. Therefore it is expected that a computer system that can help recognize the Hiragana Images. With this pattern recognition Application of Hiragana Images, it is expected the system can be developed further to recognize the Hiragana Images quickly and precisely.

Published: October 2020

One of the main aspects of improving health for the elderly is the maintenance of sleep to ensure recovery of bodily functions to an optimal functional level. The elderly will experience physical, psychosocial and spiritual changes with age. One of those changes is the change in sleep quality. Changes in sleep quality is one of the problems caused by the degeneration process in the elderly. Determining the effect of morning walking on the latency and duration of sleep in the elderly. This type of research is a “pre-experiment” research with one group pre-post-test design research design. A total of 20 study subjects carried out walking interventions in the morning as far as 1,800 meters. Before the intervention is pre-tested, then the walking exercise intervention was carried out 5 times a week in the range of 07.00 am-08.00 am. It was observed and accompanied by researchers together with the research team. The intervention was carried out for 2 weeks and continued with a post-test given to respondents to determine the latency and duration of sleep by asking respondents to return the questionnaire filled out by researchers. The results of the latency variable before the intervention were dominated by less categories i.e., 50% but after the intervention the good category increased by 25% the statistical test results showed a p value of 0.001. Sleep duration which was initially dominated by bad category, after intervention the good category became 10% and has a p value of 0.002. Morning walking exercise influences the latency and duration of sleep in the elderly.

Published: October 2020

Hypertension is a degenerative disease that is common in elderly. This can be a risk factor for stroke, heart failure, and coronary disease. One of the factors of hypertension is high cholesterol levels, lack of sports activities, and poor food consumption habits. This study aims to investigate the effectiveness of the Walking, Passion fruit and Mineral Water (JAKI-MAAP) intervention on blood pressure and cholesterol levels in the elderly with hypertension and high cholesterol. This study conducted a quasi-experimental design. This study analyzed the effect of JAKI-MAAP treatment on cholesterol levels and blood pressure levels before and after treatment. By using purposive sampling technique, the number of respondents was 15 respondents in the treatment group and 15 respondents in the control group. The results showed that there was an effect of JAKI-MAAP on the average level of cholesterol reduction in the intervention group of 32 mg/dl (p= 0.000) and the control group 10.13 mg/dl (p= 0.003).

Published: October 2020

Type-1 lepra reaction commonly occurs in borderline leprosy as a result of cellular immune response toMycobacterium lepraeantigen, and it’s characterized as acute inflammation. Clinical manifestations of type-1 lepra reaction are leprosy lesions with or without ulceration, edema, neuritis, permanent nerve damage and disability. Interleukin-17 (IL-17) and interferon gamma (IFN-γ) tests in leprosy patients can help in anticipating type-1 lepra reaction that commonly causes disability. This case control study was carried out from March to July 2015 in 60 borderline leprosy patients with and without type-1 reaction at Skin and Venereal Unit of Dr. Soetomo Teaching Hospital, Surabaya, Indonesia. We used ELISAto measure IL-17 and IFN-γ levels. We found a significant IL-17 level difference between borderline leprosy patients with and without type-1 reaction (3.7 pg/mL vs. 3 pg/mL;p= 0.005). On the other hand, there was no significant IFN-γ difference between borderline leprosy patients with and without type-1 reaction (53.15 pg/mL vs. 44.15 pg/mL;p= 0.680). IL-17 had a more dominant role in type-1 lepra reaction. There was a significant IL-17 level difference between borderline leprosy patients with and without type-1 reaction.

The intensity of the solar radiation and the surface area of the photovoltaic module directly influence the amounts of electricity produced by the photovoltaic module. This needs to be known to determine the design of an effective solar power system for the use of electricity from solar energy sources. This research aims to determine the influence of the intensity of solar radiation and the area of the photovoltaic module on the performance of the photovoltaic module in producing current and voltage to be distributed to charge the battery. The method used in this research is an experimental method that measures the current and voltage of the photovoltaic module, the intensity of the solar radiation, the temperature, and the surface area of the photovoltaic module the equipment used is 600 Wp photovoltaic module, ammeter, voltmeter, luxmeter, solar charge controller, batteries and temperature gauges. Results of the research show the intensity of the solar radiation is directly proportional to the battery charging current. The intensity of the solar radiation up to 10000 lux produces a charging current on a 100 Ah 12 volt battery that is 0 to 1.55 Amperes, for 10000 lux to 60000 lux produces 1.6 to 8.35 A, for 60000 lux to 90000 lux produces 9 to 14 A and for above 90000 lux produces 14 to 19 A. The ratio of the surface area of the photovoltaic module is proportional to the ratio of the battery charging current and the increase in battery voltage. Photovoltaic modules with a surface area ratio of 1:2:3, produce a battery charging current and voltage that is 1:2:2.7 and 1:2.1:3.1. Comparison of the amount of electricity produced by a photovoltaic module is proportional to the ratio of the surface area of a photovoltaic module if the measurements are made at the same place and time, at the same scc (solar charge controller) and at the same initial voltage of the battery.

The method of thermal imaging inspection allowing detecting defects at an early stage of their development is considered. The essence of the method consists in recalculation of measured temperature drops into insulating characteristics measured under operating voltage. It is shown that defects are detected at the early stage of their development using the defect detection criterion (tgδmeas-tgδcalc). It is concluded that it is possible to abandon a number of traditional methods of testing with electrical equipment shutdown.

Published: October 2020

High heavy metal contents in soil of abandoned coal mining pose a risk to the environment. Acidic conditions impose a potential mobilization and availability of toxic heavy metals to water body. The objective of this study was to reduce mobilization of manganese and cadmium in the soil by amending lignite base biochar. The immobilization was investigated in a fixed bed column experiment in which concentrations of the metals in aliquot after the column were compared. Demineralized water adjusted to pH 4.7 to mimic environmental condition was pumped up through the column and the aliquots were collected at empty head space at liquid to solid (L/S) ratios of 1, 2, 5, 8 and 10. The results show that biochar amendment improves fraction of Mn and Cd immobilization in the soil and reduces mobility and availability of the metals. Amendment of 10% biochar could immobilize Mn (30%) and Cd (1%), respectively.
Distance Estimation Based on Deep Convolutional Neural Network Using Ultra-Wideband Signals

Published: October 2020

Recently, high accuracy localization technique is required to provide indoor location services. The purpose of this paper is to propose a distance estimation technique based on deep convolutional neural network (DCNN) for indoor environments. Among distance estimation techniques based on wireless communication signals, the use of ultra-wideband (UWB) signals has the advantage of high accuracy in the time domain. The proposed distance estimation method uses UWB signals and proposes a new DCNN-based distance estimator. The superiority of the proposed method is confirmed through computer simulation. Widely used conventional distance estimators are based on the power threshold. The threshold is determined by signal to noise ratio (SNR) of the received signal. The arrival time of the received signal that exceeds the threshold is considered as the time-of-arrival (ToA) and the distance between transmitter and receiver is obtained from the ToA. On the other hand, the proposed distance estimator requires only the received signal without SNR estimation, which make the proposed technique simpler to implement. According to computer simulation, the conventional method is highly sensitive to SNR and distance. In contrast, the proposed method shows less than 2 m root mean square error (RMSE) performance in a wide range of SNR and the RMSE performance is not degraded in long distances. The proposed distance estimator shows excellent distance estimation performance at low SNR and long distance, so it can be applied to indoor localization system of large indoor space and can be used for precise location service.
