Attraction and repulsion forces in melt-textured and sintered YBCO-superconductors: a comparative study

In this paper, we measure the attraction (suspension) and repulsion (levitation) forces produced by the interaction between a permanent magnet and different bulk superconductors. The measurements of the interaction force HTS-PM were carried out with a relatively simple technique developed by us, which is reproducible, reliable and low cost. The obtained results were analyzed with the Bean’s critical-state model assuming a uniform magnetic field applied to the superconductor. Two superconducting samples of YBa 2 Cu 3 O 7-δ (YBCO) prepared by solid-state reaction method and by the melt-textured growth method (MTG) were used. Both samples presented a different hysteresis behaviour in the field cooling (FC) and zero field cooling (ZFC) regimes. Levitation and suspension phenomena were observed in the MTG sample; however, the sintered sample (S) with Oxygen deficiencies (δ > 0.15) displayed a slight levitation force but did not show a suspension force, the latter one attributed to a more efficient magnetic flux pinning. Additionally, the critical current density of both samples was determined from the maximum gap of the force (ΔF) in the FC regime. The obtained values were between 43.00 A/cm 2 and 2,758 A/cm 2 for the sintered and MTG samples, respectively. These values show a remarkable difference between sintered and MTG samples like that observed from magnetization measurements, which indicate that attraction and repulsion force measurements could provide a rapid and reliable characterization method of polycrystalline superconducting samples.
Estimation Comparison of Small-Scale Fisherman Decision on Choice Fishing Gear and Outboard Engine Power

Although, the policy of infrastructure support program from the local government of Barru district South Sulawesi province Indonesia in the form of fishing gear and outboard machine has been done but the change of income of catching business has not sufficient for household economy needs of small-scale fishermen. The purpose of this article is to estimate the small-scale fisherman’s decision in selecting capture technology (fishing gear and outboard engine power) in Indonesia using model estimation model logit equation. The type of research used is explanatory method. The findings indicate that small-scale fisherman decision in choosing fishing gear is positively influenced by the income of catching business and the number of members covered and negatively by regional differences while the age of fisherman, education, side occupation and regional differences have no significant effect. Another case of fisherman decision in choosing the power of outboard engines is positively affected by the income of catching businesses and the number of members who are covered and negatively by different regions. While the age of fishermen, the number of family members, side jobs and regional differences have no significant effect.
A Critical Exploration of Agonistic Participatory Design

Abstract Agonism is often described as a means for designers and citizens to reveal and contest hegemonies in society. This paper explores how agonism used within participatory design processes can enable participants to question power structures embedded in projects, express diverging views and renegotiate project frames. The potential for reaching the democratic ideals of participation thereby increases. However, there are challenges with agonism that are yet to gain momentum in the design discourse. The purpose of this paper is to identify these challenges. This is done by reflecting on a community-based tourism development project in Kenya. The reflection illustrates that not everybody may feel comfortable with sharing views in democratic forums, that people have varying preconditions for engaging in agonism and that a multitude of hegemonies exists within projects. It also highlights a need to reflect on the transferability of agonism, at a time when participatory design moves across cultures.

A Review of Hydrogen Direct Injection for Internal Combustion Engines: Towards Carbon-Free Combustion

A paradigm shift towards the utilization of carbon-neutral and low emission fuels is necessary in the internal combustion engine industry to fulfil the carbon emission goals and future legislation requirements in many countries. Hydrogen as an energy carrier and main fuel is a promising option due to its carbon-free content, wide flammability limits and fast flame speeds. For spark-ignited internal combustion engines, utilizing hydrogen direct injection has been proven to achieve high engine power output and efficiency with low emissions. This review provides an overview of the current development and understanding of hydrogen use in internal combustion engines that are usually spark ignited, under various engine operation modes and strategies. This paper then proceeds to outline the gaps in current knowledge, along with better potential strategies and technologies that could be adopted for hydrogen direct injection in the context of compression-ignition engine applications—topics that have not yet been extensively explored to date with hydrogen but have shown advantages with compressed natural gas.
Solder Joint Recognition Using Mask R-CNN Method

This article proposes a novel solder joint recognition method based on the state-of-the-art Mask Region-convolutional neural network (R-CNN) deep learning method. Traditional classification methods, such as neural networks and statistical methods, can only classify defect type, and the template-matching method can only match the position of the object. Based on Mask R-CNN, our proposed approach can classify, position, and segment the solder joint defect at the same time. To train our Mask R-CNN-based detection method, the transfer learning method uses the ResNet-101, which is initialized and trained on the Microsoft COCO data set. Through experimentation, our proposed method obtained better results than the traditional classification method in solder joint recognition, and it can achieve very high classification accuracy with more than 95% mean of average precision (mAP) for segmentation. The proposed method can classify and identify the position and segment of the solder joint defect simultaneously with very high recognition accuracy.
Investigation of a Direct Liquid Cooling System in a Permanent Magnet Synchronous Machine

A high demand for electrification of the transport sector has resulted in a need to provide compact and reliable electric power trains where the electric machine is a key element. The cooling system has a strong impact on the specific torque and power capability of the machine. The selection of the cooling solution should not be based on the steady-state cooling performance only but also on the transient characteristics owing to the typical operational load nature of the propulsion system, where the load is not continuous (as it usually is in industrial applications), but it frequently varies in time depending on the vehicle type and the driving style. This article investigates in detail the cooling capabilities of a direct winding liquid cooling solution and compares it with a traditional frame liquid cooling arrangement in the transient condition. As a result of the comparison, it was found that the location of heat removal close to the heat source makes the temperature transient time faster, which allows to apply overload operating points more frequently.

A STUDY OF PREVALENCE OF ORAL PRECANCEROUS LESIONS IN RELATION TO TOBACCO HABITUATION

Background: Oral cancer is a becoming leading global cause of morbidity and mortality. It is one of the ten most common cancers in the world. Oral cancer is almost all the time preceded by some type of precancerous lesion. Early detection and elimination of the causative risk factor like tobacco can help in the reduction of the incidence of oral cancer. Aims and Objectives: To study the prevalence of oral precancerous lesions and its correlation with the use of tobacco in tobacco habituated population. Material and Methods: This one year duration study was undertaken on 106 employees of a charitable trust. After taking detailed history about tobacco habituation they were screened for the presence of oral precancerous lesions. Only clinical criteria were used for diagnosis of oral precancerous lesions. Efforts were also made to motivate them to quit the tobacco habit. Results and Observations: Out of total 106 subjects studied, 57 (53.77%) were tobacco users. Prevalence of oral precancerous lesions was (47.16%) in our study population, and all the lesions were exclusively seen in tobacco habitual. In tobacco habitual, oral leukoplakia as a sin- gle lesion was found in 18 cases, Erythroplakia in 9 cases and oral sub mucous fibrosis in 16 cases. A total of 9 (14%) subjects were showing multiple oral precancerous lesions. Conclusion: Tobacco acts as a major risk factor in the development of single or multiple oral precancerous lesions and they could be identi- fied by simple oral cavity examination before they undergo malignant transformation.
Effects of Electroacupuncture of "Zusanli" on Brain-gut Peptide Contents in Rat Pituitary Gland and Peripheral Blood and on the Immune System

Objective: To investigate effects of electroacupuncture (EA) of "Zusanli" (ST 36) on changes of SP immunereactivity (IR) and VIP IR contents in rats' pituitary gland and peripheral blood as well as on cellular immune, and to explore the regulatory effect of EA on the nerve endocrine immune regulatory network. Methods: 40 SD rats were evenly randomized into normal control, "Zusanli" EA, immunosuppressive model, non acupoint and "Zusanli"+immunosuppressive groups. Immunosuppressive model was established by intraperitoneal (ip)injection of cyclophosphamide (CY,100 mg/kg). Non acupoint was located about 0.5 cm beside "Zusanli" (ST 36). Both "Zusanli" and non acupoint were punctured and stimulated with electrical parameters of frequency 2 Hz, strength 3 V, intermittent waves and duration of 30 min. Acupuncture treatment was given once daily continuously for 7 days. Changes of SP IR and VIP IR contents in the pituitary gland and peripheral blood were determined by radioimmunoassay. By using micro whole blood direct immunofluorescence staining and flow cytometer T lymphocyte subpopulations were assayed. Erythrocyte immunity indexes including red blood cell C 3b receptor rosette (RBC C 3bRR) and red blood cell immune complex rosette (RBC ICR) were determined using immunoadhesion yeast rosette method. Results: Following ip of CY, SP and VIP contents in blood and pituitary gland, CD + 4% and RBC C3bRR rate reduced significantly in comparison with normal control group (P0.01). Hypophysis and blood SP and VIP contents, percent of CD + 4, RBC C 3bRR and RBC ICR in "Zusanli" group were significantly higher than those of control group (P0.01). While CD + 8% in "Zusanli" and immunosuppressive groups had no evident changes compared with control group (P0.05). In addition, both changes of CD + 4 and SP and VIP contents, and those of CD + 4 and RBC C3bRR presented a significantly positive correlation (P0.05～0.01). There were no significant differences between "Zusnali" +immunosuppressive group and control group, and between non acupoint group and control group in the above mentioned indexes (P0.05). Conclusion: Acupuncture can raise the immunity of the body , that may be closely associated with the increased synthesis and release of SP and VIP in thepituitary gland and peripheral blood, facilitating modulation of the nerve endocrine immune regulatory network.
An Accurate, Light-Weight Wind Speed Predictor for Renewable Energy Management Systems

This paper proposes an approach for accurate wind speed forecasting. While previous works have proposed approaches that have either underperformed in accuracy or were too computationally intensive, the work described in this paper was implemented using a computationally efficient model. This model provides wind speed nowcasting using a combination of perturbed observation ensemble networks and artificial neural networks. The model was validated and evaluated via simulation using data that were measured from wind masts. The simulation results show that the proposed model improved the normalized root mean square error by 20.9% compared to other contending approaches. In terms of prediction interval coverage probability, our proposed model shows a 17.8% improvement, all while using a smaller number of neural networks. Furthermore, the proposed model has an execution time that is one order of magnitude faster than other contenders.

Practical value. Using the proposed technique, it is possible to determine the parameters of the discharge circuit at which test voltage pulses are formed on the load capacitance without distorting the shape of the pulse front.
Research on China’s photovoltaic modules recycling models under extended producer responsibility

ABSTRACT The global photovoltaic (PV) industry has been developing rapidly in recent years. We have to face the dilemma of waste PV modules at the end of their life. It is important for government to construct recycling system to collect waste PV modules in the future. This paper analyses the three recycling models under Extended Producer Responsibility (EPR) from the perspective of reverse supply chain. The Government Subsidy is taken into account in the recycling model as an incentive factor. This paper examines the level of the PV producer’s recycling responsibility which is expressed by the recycling proportion of producers. The results show that there are some general rules about recycling responsibility by comparing the results of different models. What’s more, a coordinating way is designed in mixed recycling model within a certain recycling scale range in order to cut down the producer’s recycling cost. Our research shows that the coordinating way is a great method with practical value when it is difficult for the government to implement a complete EPR system.

Fatigue Reliability Analysis of Rib-To-Deck Joints Using Test Data and In-Situ Measurements

In this paper, the fatigue performance of rib-to-deck joints in orthotropic steel decks (OSDs) using thickened edge U-ribs (TEUs) and the OSD using conventional U-ribs (CUs) are investigated based on the fatigue test result and in-situ monitoring data. Firstly, comparative fatigue tests were carried out with full-scale rib-to-deck specimens. Probability–stress–life (P–S–N) curves were derived through the test data measured from a total of 18 specimens, including 7 CU specimens and 11 TEU specimens. According to the results, the TEU can lead to a notable enhancement in the fatigue strength of rib-to-deck joints, i.e., 21.4% in terms of nominal stress and 21.1% in terms of hot spot stress. After that, a typical OSD steel bridge was selected as the prototype to investigate the fatigue performance of rib-to-decks in the OSD using TEUs under actual applications. In the analysis, the uncertainty in both fatigue strength, and vehicle loads were considered. A multi-scale finite element model of the prototype bridge was established, and numerical analysis conducted to derive the vehicle-induced stress spectra of the rib-to-deck joints in critical positions. In the derivation, a stochastic traffic model was employed, through which the in-situ measurement was incorporated. Finally, fatigue reliability analysis was carried out for the prototype bridge based on the above works. The result showed that a notably higher fatigue reliability can be expected in the rib-to-deck joint in OSDs using TEUs when compared with the joints in OSDs using CUs, which in turn can lead to notable improvement in fatigue life. For instance, under the target reliability of 2.3, the fatigue life of the two critical rib-to-deck joints were, respectively, increased by 153% and 155% when using TEUs.
