Complementary split-ring resonator and strip-gap based metamaterial fractal antenna with miniature size and enhanced bandwidth for 5G applications

This paper proposes two different types of metamaterial (MTM) antennas for fifth-generation (5G) mid-band frequency operation. The radiating patch of the proposed antenna is based on the combined Minkowski-Sierpinski carpet fractal structure. On the ground plane, two different types of MTM structures: Complementary split-ring resonator (CSRR), and Strip-gap are etched to enhance the overall bandwidth and gain of the antenna. The introduction of these structures on the ground plane also leads to antenna miniaturization. Both the proposed MTM structure based antennas resonate at 3.5GHz. The overall size of the two fabricated prototypes is 28×29.5 mm2 / 28×28.5 mm2, which shows the compactness of the proposed design by 43% / 42% as compared to the conventional microstrip patch antenna (MPA). The measured bandwidth/gain achieved by the proposed combined Minkowski-Sierpinski carpet fractal antenna (CMSFA) having CSRR MTM and strip-gap etched on the ground plane are 370 MHz / 2.42dBi and 440 MHz / 3.75dBi, respectively.
6D pose measurement of metal parts based on virtual geometric feature point matching

The 6D pose measurement of metal parts is of significance in intelligent manufacturing. This paper proposes a new method which provides a solution through the utilization of geometric features for pose measurement problem in intelligent manufacturing. The proposed method extracts the geometric features in the image and then calculates and matches the virtual geometric feature points according to the pose relation of the geometric features. We propose an algorithm to implement the method. Specifically, the straight lines and ellipses are extracted from the edges and the holes of parts as the geometric features. The crosspoints of the lines and the centers of the ellipses are calculated and utilized as virtual geometric feature points. In addition, to address the fact that the geometric features cannot be easily detected in a single image, this paper proposes a feature extraction method based on multi-image fusion. The experimental results demonstrate that the proposed method can achieve high robustness and accuracy.

Influence of particle size distribution of conventional fine aggregate and construction demolition waste aggregate in Portland cement mortar

Recycled aggregates present a varied mineralogical composition and the grading of these particulates over their particle size distribution influence the aggregate properties as well as those of the composites that they form. This study proposed a comparative investigation of the influence of the particle size distribution of fine aggregates from two different origins, namely, natural crushed stone and construction and demolition waste (CDW). Three particle size distributions were defined, so that each aggregate had its fineness modulus (FM) ranked in the granulometric ranges, following the NBR 7211 Brazilian standard. The following tests were carried out: consistency, bulk density in the fresh state, compression strength, absorption (by immersion and capillarity), dimensional and mass variation. The results showed that the aggregate mineralogical composition impacted the mortar properties and that, when analyzed along with the particle size distribution, CDW showed different and varied behavior as a function of its particle size and distribution. Another finding was that mortars produced with CDW aggregate with granulometry below the lower optimal zone (FM<2.20) presented reduced mechanical and physical performance. Therefore, it was concluded that CDW aggregates should not be included in the same standards as conventional aggregates regarding the fine aggregate granulometric composition.
A Novel Exponential Approach for Dynamic Event-Triggered Leaderless Consensus of Nonlinear Multi-Agent Systems Over Directed Graphs

This brief addresses the event-triggered (ET) consensus of nonlinear multi-agent systems (MASs) over directed graphs. A new nonlinearity condition is presented which can be applied specifically for ET consensus of a class of nonlinear MASs. The proposed condition is employed to design distributed consensus controller with exponential stability via dynamic ET mechanism for nonlinear systems. Based on the proposed condition, the resultant dynamic ET consensus approach guarantees elimination of the Zeno behavior. In contrast to existing linear studies, both handling of nonlinear dynamics and design of dynamic ET mechanism for nonlinear MASs are addressed. Simulation results are provided to verify the proposed approach.

The Road from Money to Happiness

Nowadays, companies must be concerned with the levels of satisfaction and happiness of employees. Hence, this paper proposes to investigate the links between salary and happiness through an exploratory study with a quasi-experimental design. The sample included 376 respondents, and we employed structured equation modeling (SEM) in ADANCO. Prior to evaluating the structural model, the goodness of fit shows moderate/excellent values. Our empirical results show a positive relationship between salary and happiness, salary and life satisfaction, salary and financial satisfaction, financial satisfaction and life satisfaction, and financial satisfaction and happiness. Thus, we consider that our research contributes to the literature by analyzing the relationship between income and happiness in a developing country such as Romania. Congruent with previous findings, we consider that our results provide evidence of the road from salary to happiness in developing countries.
Recognition of emotions in music through the Adaptive-Network-Based Fuzzy (ANFIS)

This study aims to recognise emotions in music through the Adaptive-Network-Based Fuzzy (ANFIS). For this, we applied such structure in 877 MP3 files with thirty seconds duration each, collected directly on the YouTube platform, which represent the emotions anger, fear, happiness, sadness, and surprise. We developed four classification strategies, consisting of sets of five, four, three, and two emotions. The results were considered promising, especially for three and two emotions, whose highest hit rates were 65.83% for anger, happiness and sadness, and 88.75% for anger and sadness. A reduction in the hit rate was observed when the emotions fear and happiness were in the same set, raising the hypothesis that only the audio content is not enough to distinguish between these emotions. Based on the results, we identified potential in the application of the ANFIS framework for problems with uncertainty and subjectivity.

Controllable self-Kerr nonlinearity in a doubly dressed five-level atomic conformation

We theoretically investigate the linear and nonlinear optical properties of a five-level atomic system interacting with multiple electromagnetic fields. The relevant optical Bloch equations are numerically solved via iterative formalism to procure firstand third-order susceptibilities. Our numerical computations reveal that the switching field’s strength can be used as a knob to get either single or multiple transparency windows. It is also identified that colossal Kerr nonlinearity exists within the optical EIT dips. Furthermore, we found that the position, sign and magnitude of self-Kerr index can be manipulated by merely adjusting the Rabi frequency of switching field. We also resort to double dressed state mechanism in order to justify our numerical results. Our findings are of particular interest in multi-channel communication, quantum computation and designing of optical devices.
CHEMICAL CONSTITUENTS OF SOME WELLS WATER IN SINAI (EGYPT) AND THEIR SUITABILITY OF QUALITY TO DIFFERENT USE ACTIVITIES

The study site of Wadi Sidri locates at west central Sinai, on the eastern side of the Suez Gulf. Wadi Sidri is considered one of the most important hydrographic basins in Sinai Peninsula because it receives, seasonally a considerable amounts of rainfall, most of it flows in the form of floods towards the Suez Gulf. Other amounts of these rainfalls are surface run off and catchment or stored as groundwater in a lot of wells amongst the area of study. The present investigation aims at studing the chemical constituents of groundwater of the wells in Wadi Sidri, and to evaluate their suitability for irrigation or for other uses in different agriculture proposes; sharing in the development of the area. Chemical analysis for 21 ground water samples were collected from 21 selected wells from Sidri valley. Data can be summarized as follow:  Relatively use of groundwater in different human activities depend upon the general moderate values of pH, TDS, SAR, pHc and adj SAR and adj RNa.  Hydro-chemical parameters intended that the determination of the ion ratios is important to distinguish between groundwater having pale salinity characteristics and those mineralized resulting by evaporation processes. The most important parameters are: (Na + K) / Cl, (SO4 / Cl), (Ca / Mg) and (Na / K).  The hypothetical salts assemblages in groundwater result from the combination between cations and anions. Groundwater of the studied wells reflect the existence of two assemblages salts of; NaCl, MgCl2, MgSO4, CaSO4 and Ca (HCO3)2 beside to NaCl, Na2SO4, CaSO4, MgSO4 and Ca (HCO3)2.  Many heavy and trace elements (Fe, Mn, Zn, Cu, Pb and Cd) are present in groundwater with low concentration (less than 0.lppm), but sometimes much higher, particularly if the water has been in contact with mineralized rock or ore bodies.
A Compact SIW Cavity-Backed Self-Multiplexing Antenna for Hexa-Band Operation

In this communication a compact planar-fed substrate integrated waveguide (SIW)-based self-multiplexing (SM) antenna for hexa-band operation is proposed for the first time. Six different patches with planar $50~\Omega $ feed lines are designed and attached to the top side of the rectangular SIW cavity. The antenna operates at six different frequencies (5.33, 5.76, 6.31, 6.86, 7.34, and 7.8 GHz) simultaneously. The antenna attains 4.5, 4.94, 4.9, 5.12, 6.12, and 6.6 dBi peak gain at respective resonant frequencies. Port relocation, stepped patches, and additional vias are exploited to maintain isolation (>23 dB) between any two ports. The front-to-back ratios (FTBRs) are between 10 and 20 dB and Co-pol to Cross-pol ratios are between 10 and 29 dB. The design supports single-variable independent frequency tuning for all six patches and eligible for wide range of applications. The proposed design is fabricated and results are validated through measurement. The antenna is suitable for planar microwave devices.

The OpenSees computational platform has allowed unprecedented opportunities for conducting seismic nonlinear soil-structure interaction simulations. On the geotechnical side, capabilities such as coupled solid-fluid formulations and nonlinear incrementalplasticity approaches allow for representation of the involved dynamic/seismic responses. This paper presents recent research that facilitated such endeavors in terms of response of ground-foundation-structure systems using advanced material modeling techniques and high-performance computing resources. Representative numerical results are shown for large-scale soil-structure systems, and ground modification liquefaction countermeasures. In addition, graphical user interface enabling tools for routine usage of such 3D simulation environments are presented, as an important element in support of wider adoption and practical applications. In this context, Performance-Based Earthquake Engineering (PBEE) analysis of bridge-ground systems is highlighted as an important topical application.
Linkage of ABO blood groups with ischemic stroke

Aim: Like cancer and myocardial infarction, the cerebrovascular accident causes death and morbidity in adults. Ischemic stroke is the most common type of stroke. Predisposing conditions to other cardiovascular diseases similarly play a facilitating role for stroke. The association of ABO blood types with several illnesses as described in previous studies. In this retrospective observational study, our purpose is to show the contribution of ABO blood types in ischemic stroke patients. Our study is important because it is a rare analysis elucidating the link between ABO blood groups with IS risk in the Turkish population. Materials and Methods: 1,540 cases diagnosed with ischemic stroke and 20,863 healthy subjects determined as the control group was included in this research. Ischemic stroke cases and the healthy subjects were between 45-90 years old. Both these groups were examined for blood group analysis. Results: When the patients and healthy subjects were examined in terms of blood group distributions, the blood group type distribution within each group had similar characteristics. In terms of Rh status and Blood type distribution, Ischemic stroke cases, and the healthy subjects were not statistically different from each other. Conclusion: We were not able to show any relation between ischemic stroke and ABO blood type in our study.
Helping Automated Vehicles With Left-Turn Maneuvers: A Game Theory-Based Decision Framework for Conflicting Maneuvers at Intersections

The deployment of connected, automated vehicles (CAVs) provides the opportunity to enhance the safety and efficiency of transportation systems. However, despite the rapid development of this technology, human-driven vehicles are predicted to predominate the vehicle fleet, compelling CAVs to be able to operate in a mixed traffic environment. The key to achieving a reliable and safe human-CAV collaboration in such environments is to characterize the interactions between the actors and incorporate the underlying decision-making mechanism of human drivers into CAVs’ motion planning algorithms. Towards this goal and extending a previously developed game theoretical model, the present study proposes a decision-making dynamic to achieve more realistic models of human behavior when making conflicting maneuvers at intersections. A novel field test is conducted to extract the required modeling data directly from CAVs’ perception system, facilitating the incorporation of the model into CAV navigation algorithms. Model validation and sensitivity analysis provided invaluable insights into the nature of human decisions and indicated that the proposed structure is robust to environmental uncertainties and can well capture the real-world behavior of human drivers in unprotected left-turn maneuvers. The derived knowledge can be directly used in CAV motion planning algorithms to provide the vehicle with more accurate predictions of human actions when operating in mixed traffic environments.
Differential Responses of Soil Bacterial and Fungal Community to Short-Term Crop Tree Management in a Larix gmelinii Plantation

Crop tree management (CTM) is a widely applicable silviculture technology that is used to improve the performance of individual trees. However, only little information is available about the effects of the CTM regime on the soil microbial community structure. We conducted a study to explore the effects of short-term (five years) CTM on the soil bacterial and fungal diversity, community composition, and structure in the 0–10 cm soil layer in a Larix gmelinii (Rupr.) Kuzen. plantation. We set out to investigate the differential response of bacterial and fungal communities to variations in soil properties mediated by short-term CTM. Compared with the control plots, the soil microbial biomass carbon and microbial biomass nitrogen in CTM increased significantly by 64.2% and 32.3%, respectively. CTM significantly promoted the content of soil organic carbon, dissolved organic carbon, and nitrate nitrogen, and reduced the content of dissolved organic nitrogen. CTM changed the Shannon and Simpson indices of soil fungi to a remarkable extent but had little effect on the α diversity of bacterial communities. The bacterial β diversity was more sensitive to CTM than fungi. The relative abundance of Verrucomicrobiae (the dominant class of soil bacteria) in CTM was significantly increased by 78.2%, while the relative abundance of Agaricomycetes (dominant class for soil fungi) was reduced by 43.3%. We observed a significantly increased number of unique OTUs for soil fungi in the CTM plots. Redundancy analysis showed that dissolved organic carbon, soil moisture, and total phosphorus content significantly affected the composition of bacterial communities, while soil dissolved organic nitrogen, C/N, and total phosphorus drove the high variation in fungal community composition. Overall, our results emphasize the divergent response of soil bacterial and fungal communities in Larix gmelinii plantations to short-term CTM. We must pay more attention to the functional role of soil microbiota in future forest management.
Effect of Direct Statistical Contrast Enhancement Technique on Document Image Binarization

Background: Contrast enhancement plays an important role in the image processing field. Contrast correction has performed an adjustment on the darkness or brightness of the input image and increases the quality of the image.Objective: This paper proposed a novel method based on statistical data from the local mean and local standard deviation.Method: The proposed method modifies the mean and standard deviation of a neighbourhood at each pixel and divides it into three categories: background, foreground, and problematic (contrast & luminosity) region. Experimental results from both visual and objective aspects show that the proposed method can normalize the contrast variation problem effectively compared to Histogram Equalization (HE), Difference of Gaussian (DoG), and Butterworth Homomorphic Filtering (BHF). Seven (7) types of binarization methods were tested on the corrected image and produced a positive and impressive result.Result: Finally, a comparison in terms of Signal Noise Ratio (SNR), Misclassification Error (ME), F-measure, Peak Signal Noise Ratio (PSNR), Misclassification Penalty Metric (MPM), and Accuracy was calculated. Each binarization method shows an incremented result after applying it onto the corrected image compared to the original image. The SNR result of our proposed image is 9.350 higher than the three (3) other methods. The average increment after five (5) types of evaluation are: (Otsu = 41.64%, Local Adaptive = 7.05%, Niblack = 30.28%, Bernsen = 25%, Bradley = 3.54%, Nick = 1.59%, Gradient-Based = 14.6%). Conclusion: The results presented in this paper effectively solve the contrast problem and finally produce better quality images.
