We have experimentally designed the cleaning system for single (Photovoltaic) PV panel. The weeper cleaning system is controlled using a microcontroller. The cleaning system operates by spraying an amount of water on the PV panel surface, and then actuating the weeper using a DC motor. Two limit switches are used to sense the weeper position at the edge of the PV panel. In the experimental test, an amount of dust is deployed on the PV panel surface to test its power performance. The experimental results have shown that the weeper can improve the efficiency of the PV panel of about 47% over the efficiency before the PV panel is cleaned. The weeper can be managed to work periodically for example five times in a day, or can be manually activated using remote control mechanism. The power performance of the weeper system is also tested. The percentage of the power consumption over total PV system power during standby condition of the weeper is about 0.79%. While during water spray and weeper operations, it consumes respectively about 8.94% and 4.49%. This low power consumption make this cleaning system feasible for further product development.","PeriodicalId":30772,"journal":{"name":"International Journal on Smart Material and Mechatronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-10-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68299146","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mineralogical properties of the ores analyzed by means of optical microscopy and X-ray diffractometry (XRD) show that samples from Barru consist mainly of rhodochrosite (MnCO 3 ) with less cryptomelane, groutite, bixbyite, and todorokite. Goethite, calcite and small amount of quartz present as impurities. Manganese ore samples from Bone are predominantly composed of pyrolusite (MnO 2 ) with subordinate ramsdellite and hollandite. Barite, quartz, hematite and clay are present as gangue minerals. Chemical compositions determined by using XRF method revealed that Barru samples contain higher in MnO (average is 40.07 wt%) than the Bone samples (average is 34.36 wt%). Similarly, Fe 2 O 3 and CaO are also higher in Barru than those of the Bone samples. In contrast, concentrations of SiO 2 and total alkali (K 2 O + Na 2 O) are lower in the Barru samples. The average P 2 O 5 content of samples in both areas is low (<0.2 wt%). Relatively higher grade of Fe 2 O 3 in the Barru ore implies that it has potential application for ferromanganese production; whereas the elevated SiO 2 content of the Bone ore is a good indication for silicomanganese manufacture. However, both ores may not favorable to be directly used as raw materials in metallurgical uses. Prior to be used, the ores should be treated by applying physical beneficiation in order to reduce deleterious elements.","PeriodicalId":30772,"journal":{"name":"International Journal on Smart Material and Mechatronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68297733","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Furthermore, the influence of oscillation condition on the electrical power generation properties of lead zirconate titanate (PZT) piezoelectric ceramics has been investigated. It is found that the power generation is directly attributed to the applied load and wave mode. The voltage rises instantly to the maximum level under square-wave mode, although the voltage increases gradually under triangular-wave mode. After this initial increase, there is a rapid fall to zero, followed by generation of increasingly negative voltage as the applied load is removed for all wave modes. Variation of the electric voltage is reflected by the cyclic loading at higher loading frequencies. On the basis of the obtained experimental results for the wave modes, the electrical power generation characteristics of PZT ceramics are proposed, and the voltages generated during loading and unloading are accurately estimated. The electric generation value is decrease with increasing the cyclic number due to the material failure, e.g., domain switching and crack. The influence of domain switching on the mechanical properties PZT piezoelectric ceramics is clarified, and 90 degree domain switching occurs after the load is applied to the PZT ceramic directly. Note that, in this paper, our experimental results obtained in our previous works were introduced [1,2].","PeriodicalId":30772,"journal":{"name":"International Journal on Smart Material and Mechatronics","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2015-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68298049","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
