In the research method, the vehicle's driving mode was analyzed according to the NEDC (New European Driving Cycle) standard. The M1 category Chevrolet Nexia used the method of measuring fuel consumption by volume in the drive cycle at the auto polygon. In this method, the capabilities of the car's design and electronic control unit were used to determine fuel consumption and vehicle speed. The data were obtained via OBD-II from onboard the vehicle through the Scanmatic diagnostic device. The diagram forms were generated using computer technology. The fuel consumption of the car is 8.0 liters per 100 km in the technical parameters. The car consumed 7.5 liters of fuel while using automatic start-stop technology in the auto polygon. The calculation method showed us the system saved 6.25% of the fuel and emitted 6.25% less exhaust gases to the environment.","PeriodicalId":19674,"journal":{"name":"Open Access Journal of Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89996370","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}

There are a few techniques to shroud inside recorded cover-photographs. The spatial area strategies control the duvet-photograph pixel-bit esteems to insert the mystery data. The mystery pieces are composed quickly to the duvet picture pixel bytes. Thusly, the spatial territory procedures are basic and simple to execute.

The successful transmission of data from the source nodes to the destination nodes depends on the reliability of the network. In the absence of good networks the IoT technology will not be able to work properly as the failure in transfer of data would result in the malfunctioning of the applications. The Quality of Services (QoS) parameters of the network helps in knowing the capability of the networks in transferring data. These parameters would help the service providers to improve the shortcomings in the network and provide better service to its users. End to end delay, packet delivery ratio, energy consumption, jitter, routing over load and throughput are some of the parameters discussed in this paper. The parameters have been calculated by the different types of network and the variation of these parameters with the change in the size of network have been studied.","PeriodicalId":19674,"journal":{"name":"Open Access Journal of Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72588027","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}

Leaching, a traditional practice to cope with salinity through flushing of soils with fresh water in order to remove excess salts from the topsoil, is no longer feasible due to disrepair and inefficient operation of the drainage networks. As a result, salinized lands are either giving very low yields and income or are abandoned, which is negatively affecting rural livelihoods. As an intermediate solution, the cultivation of licorice (Glycyrrhiza glabra) is proposed as a viable alternative, as it rehabilitates salinized soils and improves their fertility - so that major crops can be again grown profitably in these abandoned or highly saline lands. In addition to its positive impact on the sustainability of agricultural production in irrigated areas, licorice cultivation can also increase farm income thanks to the high economic value and marketability of its roots and the value of its biomass as livestock feed.  ","PeriodicalId":19674,"journal":{"name":"Open Access Journal of Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2021-03-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72860233","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}

Online transportation is on the rise in Indonesia. Sometimes seen as providing more benefits to people of Indonesia, online transportation also has its side-effects. As the number of online transportations rises, so is the level of traffic in big cities such as Jakarta. This traffic is also getting worse due to the bad driving behavior of Indonesian people, especially the online transportation driver.
