Published: January 2018

Abstract
We propose a current superimposition variable flux reluctance motor for a traction motor of electric vehicles and hybrid electric vehicles, which consists of 10 salient poles in the rotor and 12 slots in the stator. However, iron losses of this motor in high rotation speed ranges is large because the number of salient poles is large. In this paper, we propose a current superimposition variable flux reluctance motor that consists of 8 salient poles and 12 slots. The characteristics of the 10-pole-12-slot and 8-pole-12-slot current superimposition variable flux reluctance motors are compared using finite element analysis under vector control.

Abstract
Rosacea is a chronic inflammatory skin disorder affecting predominantly adult patients. The aim of the current investigation was to evaluate clinical response by using quality of life assessment before and after an IPL (intensive pulsed light) therapy course for patients sufferring from rosacea treated in the outpatient clinic “Health and Aesthetics” in Rīga during a one-year period (in 2016). All patients presented with typical clinical symptoms of rosacea on the face — acneiform papules, pustules, telangiectasia, centrofacial erythema, and complaints about flushing and burning. In the current study, 100 rosacea patients treated with IPL therapy were selected. Each patient filled in the quality of life questionnaire before and after two courses of IPL therapy. The interval between IPL therapy sessions was one month. The results reflected comprehensive benefit from IPL therapy for all rosacea patients. No serious side effects from IPL therapy were detected. Side effects like mild eythema after procedure (75%), mild oedema (10%), vesiculation (3%), and hyperpigmentation (8%) were completely resolved within four weeks after completion of treatment. In all patients, quality of life assessment showed a statistically significant increase after two courses of IPL therapy.

Authors: Rahimi-Ahar Zohreh , Hatamipour Mohammad Sadegh 
Published: January 2018

AbstractThis article reviews the major research and development on spouted beds (SBs). Due to its unique structural and flow characteristics, the SB is a very successful system in most applications. Two-phase and sometimes three-phase interactions generate a large number of variables to be noted in each process. Up-to-date information on the fundamentals and applications of SBs has been briefly presented, based on the published works. Thousands of interesting studies on hydrodynamic characteristics, numerical simulations, and new applications of SBs are reported. In the first step, the present work presents a review of hydrodynamic characteristics (circulation of solids in SB, measurement techniques for particle tracking and empirical hydrodynamics, pressure drop, maximum spoutable height, minimum spouting velocity, and diameter of the spout). In the second step, main mathematical models and computational fluid dynamics (CFD) simulation of the SB to predict and analyze different processes are described. Some main mathematical modeling and the recent advances of two fluid methods and discrete element method approaches in CFD simulation of SBs are summarized. In the last step, some new applications of the SB are presented. As the result of this review, we can observe the importance of further development of hydrodynamics structure, working on modeling and related correlations and improve the applications of SBs.

Abstract
Concrete pavements is an attractive alternative to asphalt pavements because of its lower cost and higher durability. Major contribution to sustainable development can be made by partial replacement of cement in concrete pavement with supplementary cementitious materials of different nature and origin. In this paper, the effect of natural zeolite and perlite additives in complex with chemical admixtures on the structure and properties of concrete for pavement was studied. Compressive and flexural strength test was used to study the mechanical behavior of designed concrete under load. Generally, the compressive strength of both control concrete and concrete containing mineral additives levels at the later ages of hardening. The microstructure analysis of concrete with mineral additives of different nature activity showed the formation of additional amount of hydration products such as tobermorite type calcium hydrosilicate which provide self-reinforcement of hardening concrete system.
PV Module Integrated Dual Boost Isolated dc-dc Converter Fed Three-Phase Micro-Inverter
Authors: Geetha P. , Ravi S. 
Published: January 2018

Abstract
This paper presents a photovoltaic (PV) array-integrated dual-boost isolated dc-dc converter-fed three-phase micro-inverter for the grid-connected applications. The coupled inductor and high-frequency DC link-based dc-dc converter offer more advantages over the conventional dc-dc converters used in the grid-tied PV system. A controller with an inner voltage control loop and frequency control loop is proposed to operate the converters of a micro-inverter to transfer the maximum power generated on the PV array to the grid. The inner voltage control loop generates the required control signal for the proposed high step-up dc-dc converter to extract the maximum possible power from the PV array during sunny days. It eliminates the need of cascaded connection of dc-dc converters. High maximum power point tracking (MPPT) accuracy, high voltage gain, and high energy conversion efficiency can be attained with the proposed system. The principles of operation and design considerations of the dual-boost isolated dc-dc converter-fed micro-inverter are presented. The MATLAB/Simulink simulation results are presented to validate the performance of the proposed three-phase micro-inverter.

Authors: Li Sheng , Yang Fan , Liu Zhao-Hui 
Published: January 2018

Abstract
This research was performed to improve the interlayer shear bond strength of rigid-flexible composite pavement. Based on the laboratory testing, three types of additive, which are listed as follows, were recommended and investigated to determine the optimum content of crumb tire rubber (CTR) and thermoplastic styrene-butadiene-styrene (SBS): 8 % CTR + 3.5 % SBS, 10 % CTR + 3 % SBS, and 12 % CTR + 2.5 % SBS. The high-temperature property and viscous nature of co-modified asphalts were studied by using a rotational rheometer. A temperature sweep and a shear fatigue test were performed to characterize the dynamic mechanical performance and fatigue property of asphalt materials. The results showed that the co-modified asphalt with 8 % CTR and 3.5 % SBS performed best in a viscosity test at 60°C. At 135°C and 165°C, it exhibited good viscous nature and had the desired workability of asphalt pumping and mixing. The high-temperature grade, the dynamic mechanical performance, and fatigue property of this co-modified asphalt were of great satisfaction as well. Therefore, 8 % CTR + 3.5 % SBS is recommended as a modifying material for construction and design purpose.

Transmission electron microscopy was applied to study defects in laterally overgrown GaN layers, with initial growth on Al2O3 substrates followed by further growth over SiO2 masks. Dislocations found in the overgrown areas show changes in line direction. Most dislocations propagate along c-planes. In the overgrown material planar defects (faulted loops) are present on c-planes and their presence is most probably related to segregation of excess point defects and impurities present in this material. They appear to be initiated by the fast lateral growth. Some dislocations with screw orientation become helical resulting from climb motion.Formation of voids and also a high dislocation density was observed at the boundaries where two overgrowing fronts meet. Tilt and twist components were observed for these boundaries that were different for different overgrown strips grown in the same crystallographic direction suggesting that the GaN subgrain orientations on the two sides of a SiO2 mask are responsible for the final tilt and twist value.
Thermal Annealing of InGaN/GaN Strained-Layer Quantum Well

Published: January 2018

Quantum well (QW) material engineering has attracted a considerable amount of interest from many people because of its ability to produce a number of optoelectronic devices. QW composition intermixing is a thermal induced interdiffusion of the constituent atoms through the hetero-interface. The intermixing process is an attractive way to achieve the modification of the QW band structure. It is known that the band structure is a fundamental determinant for such electronic and optical properties of materials as the optical gain, the refractive index and the absorption. During the process, the as-grown square-QW compositional profile is modified to a graded profile, thereby altering the confinement profile and the subband structure in the QW. The blue-shifting of the wavelength in the intermixed QW structure is found in this process.In recent years, III-nitride semiconductors have attracted much attention. This is mainly due to their large bandgap range from 1.89eV (wurtzite InN) to 3.44eV (wurtzite GaN). InGaN/GaN quantum well structures have been used to achieve high lumens blue and green light emitting diodes. Such structures also facilitate the production of full colour LED displays by complementing the colour spectrum of available LEDs.In this paper, the effects of thermal annealing on the strained-layer InGaN/GaN QW will be presented. The effects of intermixing on the confinement potential of InGaN/GaN QWs have been theoretically analysed, with sublattices interdiffusion as the basis. This process is described by Fick’s law, with constant diffusion coefficients in both the well and the barrier layers. The diffusion coefficients depend on the annealing temperature, time and the activation energy of constituent atoms. The optical properties of intermixed InGaN/GaN QW structure of different interdiffusion rates have been theoretically analyzed for applications of novel optical devices. The photoluminescence studies and the intermixed QW modeling have been used to understand the effects of intermixing.

Photoluminescence (PL) and photoluminescence excitation (PLE) spectroscopy have been carried out at 6K on the 1540 nm 4I13/2 → 4I15/2 emission of Er3+ in in situ Er-doped and Erimplanted GaN grown by hydride vapor phase epitaxy (HVPE). The PL and PLE of these two different Er-doped HVPE-grown GaN films are compared with Er-implanted GaN grown by metal organic chemical vapor deposition (MOCVD).In the in situ Er-doped HVPE-grown GaN, the lineshape of the broad PLE absorption bands and the broad PL bands is similar to that in Er-doped glass. The PL spectra of this in situ Er-doped sample are independent of excitation wavelength, unlike the PL of the Er-implanted GaN. These PL spectra are quite different from the site-selective PL spectra observed in the Er-implanted GaN, indicating that the seven different Er3+ sites existing in the Er-implanted MOCVD-grown GaN are not observed in the in situ Er-doped HVPE-grown GaN. Four of the seven different Er3+ sites observed in the Er-implanted MOCVD-grown GaN annealed at 900°C under a flow of N2 are present in the Er-implanted HVPE-grown GaN annealed at 800°C in an NH3/H2 atmosphere.

At present plastic becomes inseparable from human life especially in the food and beverage industry. One of the methods used in the manufacturing process of plastic products is injection molding. Injection molding is one of manufacturing technique that consists of a series of cyclical processes and is used to produce thermoplastic materials. The effect of the combination of process parameters impact on the product results such as the quantity and quality of the product, the non-conformity of the parameters causes the production to be not optimal. One method that can be used for optimization is the taguchi method. The taguchi method is a set of special matrices called orthoghonal arrays that are used as reference in the determination combination of parameters and level values. The purpose of this research is to determine the optimal cycle time and net of the product on the process of making 180 ml bottle cap but by minimizing flash defects. The method used in this phase is ANOVA, and the calculation of taguchi method by using minitab 16 software. From the result of the research, the result of optimal condition is combination injection pressure 1320 bar, injection speed 50 mm/s, holding pressure 300 bar, and nozzle temperature 255oC produces a cycle time value of 15.72 seconds and netto 3.56 grams. This result is better than the setting of the company that produces 16.66 seconds cycle time and entered in the net range of 4 ± 0.5 grams resulting in an increase in production of 5.97%. While with combination of injection pressure 1280 bar, injection speed 50 mm / s, holding pressure 300 bar, and nozzle temperature 245oC resulted in fewer number of flash defects compared to company setting that is 12 units from 80 units of sample.

THE ADMINISTRATIVE-TERRITORIAL REFORM OF YAMATO RULER – EMPEROR HOMUDA IN KIBI REGION
Authors: Surowen D. A. 
Published: January 2018

The current paper features the reasons and the content of the administrative-territorial reform introduced by Yamato ruler – emperor Homuda (Ōjin, 390 – late 414 / early 415 AD [of the corrected chronology]) in 411 AD [of the corrected chronology] in Kibi area (in western Honshu). The article contains the data obtained about the administrative-territorial units he organized and the local governors he appointed. It has been revealed that the elderly emperor delegated the rule to his three sons and retreated to Kibi area, which was the homeland of his younger wife E-hime. Upon his arrival, emperor Homuda undertook an administrative-territorial reform for the benefit of the hereditary owners of these lands, i.e. the Mitomo-wake clan. He established districts (Jap. agata) and appointed the “lords of districts” (Jap. agata-nushi). Besides, he appointed the “rulers of regions” (Jap. kuni-no miyatsuko) in the regions (Jap. kuni) of Bizen and Bicchū (in Near and Central Kibi). This reform resulted in the fact that emperor’s cousins-in-laws from his younger wife’s side rose to power in the regions (Jap. kuni) and in the newly- created districts (Jap. agata) of Near and Central Kibi.

Published: January 2018

The research uses the method of cross sections to identify the current trends in the development of representations among schoolchildren and undergraduate students. The article is an attempt to answer the following question: what is the role of individual features of representation, certain individually changeable integral features of performance at various stages of school and university education? It features the results of the study of the integral characteristics (brightness-clearness, controllability and liveliness), taking into account age and different modalities of representation. This study reveals the contribution of each of the integral features of representation throughout the period of study by highlighting age-related peculiarities of formation of representations in pupils and students. The study has identified two distinct phases, characterized by different dynamics of representation formation, the school period and the higher education period. The first one displays the following features: a decrease in liveliness and a simultaneous increase in brightness-clearness, controllability, and ability to representations brightness-clearness. The second period shows an increase in liveliness and simultaneous decrease in brightness-clearness, controllability and ability to representations of the brightness-sharpness of representations.
