Monitoring Kebocoran Gas LPG Menggunakan Mikrokontroler Berbasis Website
No full textThis study describes the design of an LPG gas leak monitoring system using a website-based microcontroller. Minister of Energy and Mineral Resources Decree No: 1971/26/MEM/2007 dated 22 May 2007 concerning the conversion of petroleum, namely kerosene, into LPG gas. Much of the LPG gas used by the public has experienced a decline in the quality of gas cylinders, due to the lack of supervision of gas cylinder products so that it can be dangerous for the community. Rusty, damaged, dented gas cylinders were found, and rubber seals on the gas cylinders were damaged, which in turn could cause LPG gas cylinders to leak and even explode. Based on these problems, in this study a gas leak monitoring and control system was created using the MQ2 sensor and microcontroller. The MQ2 sensor will detect a gas leak from the volume of gas in the room. If the gas value in the room is 300 ppm, the relay will turn on and will turn on the exhaust fan. Then wemos d1 mini will display this value in the database and will be displayed on the website. This research is expected to reduce the possibility of gas cylinders exploding and fires targeting kitchens or restaurants and other places that use LPG cylinders

Ross-Ade
No full textDave Ross (1871-1943) and George Ade (1866-1944) were trustees, distinguished alumni and benefactors of Purdue University. Their friendship began in 1922 and led to their giving land and money for the 1924 construction of Ross-Ade Stadium, now a 70,000 seat athletic landmark on the West Lafayette campus. Their life stories date to 1883 Purdue and involve their separate student experiences and eventual fame. Their lives crossed paths with U.S. First Lady Eleanor Roosevelt, Henry Ford, Amelia Earhart, and Will Rogers among others. Gifts or ideas from Ross or Ade led to creation of the Purdue Research Foundation, Purdue Airport, Ross Hills Park, and Ross Engineering Camp. They helped Purdue Theater, the Harlequin Club and more. Ade, renowned author and playwright, did butt heads with Purdue administrators at times long ago, but remains a revered figure. Ross's ingenious mechanical inventions of gears still steer millions of motorized vehicles, boats, tractors, even golf carts the world over

Mapping the Energy ADE to CityGML 3.0
No full textIn order to limit the global warming to well below 2 degrees Celsius, all sectors have to reduce their greenhouse gas emissions and become more sustainable. This also includes the building sector, which is in Europe responsible for 40% of the total energy consumption (European Commission, 2020). A way to work towards this goal is by retrofitting the existing building stock to become more energy efficient. Urban Building Energy Modelling (UBEM) can help in this endeavour by identifying energy-saving potentials and thus to effectively allocate the required resources (Horak et al., 2022). Yet, UBEM involves many stakeholders which is why standards are crucial to facilitate data exchange and interoperability among them. In this context, the Energy ADE v1.0 was developed as an extension for the semantic 3D city model standard CityGML 2.0. It serves two purposes, first by storing energy related information on the individual building level, and second by providing the necessary input data for UBEM simulations (Agugiaro et al., 2018). However, in September 2021 CityGML 3.0 was released. The introduced changes directly affect the structure of the Energy ADE, which is why it cannot fully function on it anymore. This thesis therefore answers the question, how and to what extent the Energy ADE for CityGML 2.0 needs to be adapted to be conformant with the new CityGML 3.0 standard. It is accomplished by following a model-driven approach, where the UML class diagrams for the mapped Energy ADE are created first, before automatically deriving the corresponding XSD schema file. Through the lossless mapping itself, the Energy ADE is integrated as much as possible into CityGML 3.0, while also maintaining a logical symmetry. As such it accounts for the introduced changes of CityGML 3.0, by making use of the space and geometry concept, the versioning possibilities as well as the provided structures to model time-dependent data. The result is eventually tested and verified by converting a sample dataset to the Energy ADE for CityGML 3.0. This work provides an example on how other ADEs can be adapted to fit the new CityGML 3.0 standard and thus hopefully to the further establishment of it.Geomatic
A metadata ADE for CityGML
No full textWhile there exist international standards for geospatial metadata (ISO 19115), these are rarely used in practice for 3D datasets, and one of the OGC standards for 3D city models, CityGML, does not offer a mechanism to store metadata in a structured way. Having metadata in CityGML files, which are in practice often very large and complex, would provide us with the ability to quickly understand the nature of a dataset and to determine if it is relevant for a specific task. Alack of metadata introduces uncertainty into models that are already full of assumptions and estimations. In this paper, we first examine the metadata needs that are specific for 3D geographical datasets and propose ISO 19115compliant categories. We then describe how these can be used within CityGML by defining an Application DomainExtension (ADE), which allows us to store metadata for existing city objects of CityGML, as well as objects in other domain-specific ADEs. Our ADE, its schema in both UML and XSD, and sample datasets is openly accessible, and it can be easily extended to support application specific metadata. In addition the metadata elements have been added to the core of CityJSON. We also offer software to generate automatically many of the metadata categories and we propose coupling it with the source 3D dataset.Urban Data Scienc
George Ade\u27s Role in National Literature
No full textThe purpose of this study has been {l) to appraise the existing literary reputation of George Ade and (2) to determine whether or not he has made a substantial contribution to national literature.
In the investigation the hypothesis assumed was that the humor which critics see in George Ade\u27s work and the local color contribution which he made to national literature were of secondary importance to the author\u27s personal intention to be a realist.
The presupposition which has been adopted is that George Ade endeavored to be one of the exponents of the realistic movement. He recreated with his works what perhaps might be described as an authentic expression of realism in American literature. Whether Ade did or did not accomplish the realism he set out to convey in his writings, he remains a minor figure in the American annals of literature
KALEMBO ADE AS AN INSTRUMENT OF RESOLVING CONFLICT AMONG MBOJO COMMUNITY: A STUDY ON SPEECH ACT
No full textThis study aims at describing variation of meaning carried in kalembo ade as an instrument of resolving conflict among individuals and groups in Mbojo community by applying speech act analysis. Data were collected from speech events in Mbojo community and further analyzed descriptively. One type of speech acts was taken by considering its relevancy towards to focus of this study, i.e. expressive. Results showed that kalembo ade dealt with one of types of speech acts, i.e. Expressive type. The expression was found to reflect some actions, including condolences, apologies, greetings, thanksgivings, refusal, and congratulations. Hence, by viewing the context of usage, members of Mbojo community used this expression as an instrument in communication to resolve conflict, in which the phrase was used as tool to control verbal interaction during a speech event
CityGML Application Domain Extension (ADE): overview of developments
No full textThe Application Domain Extension (ADE) is a built-in mechanism of CityGML to augment its data model with additional concepts required by particular use cases. The goal of this paper is to provide an overview of the ADE mechanism and a literature review of developments since its introduction a decade ago. The discovery of publications found that currently there are 44 ADEs supporting a wide range of applications, but also application-agnostic purposes such as harmonisation with national geographic information standards. We hope this paper to double as a reference material for the developers of new ADEs.Urban Data Scienc
