Numerous of home appliance companies have put in much effort to solve this problem but there is still large room for further improvements especially in the rinse and the spin cycles of the washing machine. This work illustrates the performances of a multi-body modelled of washing machines realized with the aim to analyze the vibrational acoustic emission. An experimental measurement has been carried out using a digital sound level meter (SLM) to determine the overall noise produced by four different models of automated washing machines with a view of noting the model that has the highest sound pressure level during the three different cycles (the wash, rinse and spin). Result shows that all the machines produced their highest noise during the spinning cycle. Out of the four different model considered. IPSO HF: 304 has the highest sound level of 99.62dB during its spin cycle when maximum load of 30Kg was applied, followed by Imesa RC 23 with a 96.13dB. On the other hands, LG: Direct Drive 13 has the least sound pressure level of 84.75dB. With this knowledge in mind, one can advise a buyer which model to purchase from the market and if an operator must use the machine, how long he can operate such machine without health challenges.","PeriodicalId":202219,"journal":{"name":"EnergyRN: Other Energy Efficiency (Sub-Topic)","volume":"54 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134485291","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}

It examines how headwinds faced by developing economies due to non-natural energy crises is evidence of the fact that there are flaws and inconsistencies on the part of national stakeholders (public value agents) in keeping pace with the demand-supply requirements of power services. This inability to manage the public’s needs, a shortage of power generation from the back-end, and technical as well as political problems give rise to a vicious cycle of circular debt. The debt is being accumulated at the cost of the state’s social and economic stability. This implies that circular debt is a wider problem of public value creation, which must be addressed through a concerted and joint effort of public value agents.","PeriodicalId":202219,"journal":{"name":"EnergyRN: Other Energy Efficiency (Sub-Topic)","volume":"95 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-01-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115225717","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}

Technological headways in wireless correspondence cleared the path to the advancement of minuscule ease, low-power and multifunctional sensor nodes in wireless sensor networks. The organization layer manages routing issues in sensor networks. Since radio transmission and gathering devours enormous measure of vitality, power is a significant factor to be researched on. Vitality preservation is, in this way, a vital issue in wireless sensor networks. Progressing research includes planning routing conventions that require less vitality during correspondence along these lines expanding the networks lifetime. For the more significant part of the applications, a substitution of vitality is excessively costly. A vitality reaping wireless sensor networks utilize nodes that can gather vitality from the condition. This paper gives an overview of vitality effective routing. In any WSN application estimated information is assembled at customary spans and the equivalent is sent to the Base station (BS) by utilizing neighbouring nodes. By shaping bunches of nodes in the WSN, the deliberate information from the nodes can be collected, and the collected worth can be sent towards the BS rather than sending each estimation esteem and subsequently diminishing vitality devoured by the nodes. By receiving progressive routing conventions, it is conceivable to lessen vitality utilization extensively.","PeriodicalId":202219,"journal":{"name":"EnergyRN: Other Energy Efficiency (Sub-Topic)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2019-09-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134204502","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}

Mild climate, deindustrialization, and its demographics explain part of this differential. California energy efficiency policy is often claimed to be another key factor. A challenge in judging this claim is the heterogeneity of the real estate capital stock. Residential homes differ along a large number of physical attributes. We access a proprietary dataset from a large hotel chain that allows us to evaluate the environmental performance of comparable commercial real estate across the United States. Controlling for climate conditions and geographic location, we document that California’s commercial real estate stock is the most energy efficient at a point in time but this differential is quantitatively small. However, over the years 2007 to 2013, California’s hotels achieved much greater energy efficiency progress than hotels in other states.","PeriodicalId":202219,"journal":{"name":"EnergyRN: Other Energy Efficiency (Sub-Topic)","volume":"112 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"134464290","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}
