Towards Semantic Integration of Heterogeneous Sensor Data with Indigenous Knowledge for Drought Forecasting
In the Internet of Things (IoT) domain, various heterogeneous ubiquitous
devices would be able to connect and communicate with each other seamlessly,
irrespective of the domain. Semantic representation of data through detailed
standardized annotation has shown to improve the integration of the
interconnected heterogeneous devices. However, the semantic representation of
these heterogeneous data sources for environmental monitoring systems is not
yet well supported. To achieve the maximum benefits of IoT for drought
forecasting, a dedicated semantic middleware solution is required. This
research proposes a middleware that semantically represents and integrates
heterogeneous data sources with indigenous knowledge based on a unified
ontology for an accurate IoT-based drought early warning system (DEWS).Comment: 5 pages, 3 figures, In Proceedings of the Doctoral Symposium of the

Effect of pressure on density, porosity and flexural strength during cold isostatic press of alumina-ysz chromia cutting too
This study presented the effect of pressure on the density, porosity and
flexural strength when cold isostatic press (CIP) was applied to compact the ceramic
powders in the form of insert cutting tools. Specific composition of alumina (Al2O3)
wt.90%,yittria stabilized zirconia (YSZ) wt.10%, chromium oxide(Cr2O3) wt.0.6% and
polyethylene glycol (PEG) wt.0.6% were ball milled and hand pressed to form green
body of ceramic inserts. These green body were undergone further compaction inside
CIP with pressures variation of 200 MPa, 300 MPa, 400 MPa with 30 seconds and 60
seconds pressuring time. The ceramic composts were then sintered at 1440°C for 9 hours
before being assessed with density, porosity, Rockwell hardness (HRC) and bending
test. The results show that CIP use with 300 MPa parameters with 60 seconds shows the
best mechanical properties with relative density 95.5%, porosity 4.5% and HRC 65.5
hardness. Further assessment of microstructure revealed that the particles size distributed
evenly along fracture surface with coarse grain and porosity dominant in the certain area
Study terrestrial applications of solar cell powered systems
Terrestrial applications of solar cells and design systems are considered for those applications that show the most promise for becoming practical and accepted by users within the next five years. The study includes the definition, categorization, evaluation and screening of the most attractive potential terrestrial applications for solar cells. Potential markets are initially grouped and categorized in a general sense and are weighted in priority by their business volume, present and future. From a categorized list including marine, transportation, security, communication, meteorological and others, 66 potential solar cell applications have been cataloged. A methodology was formulated to include the criteria for evaluation and screening. The evaluation process covers all parts and components of the complete system required for each application and gives consideration to all factors, such as engineering, economic, production, marketing and other factors that may have an influence on the acceptance of the system
Urban integrated meteorological observations: practice and experience in Shanghai, China
Observations of atmospheric conditions and processes in citiesare fundamental to understanding the interactions between the urban surface and weather/climate, improving the performance of urban weather, air quality and climate models, and providing key information for city end-users (e.g. decision-makers, stakeholders, public). In this paper, Shanghai's urban integrated meteorological observation network (SUIMON) and some examples of intended applications are introduced. Its characteristics include being: multi- purpose (e.g. forecast, research, service), multi-function (high impact weather, city climate, special end-users), multi-scale (e.g. macro/meso-, urban-, neighborhood, street canyon), multi-variable (e.g. thermal, dynamic, chemical, bio-meteorological, ecological), and multi- platform (e.g. radar, wind profiler, ground-based, satellite based, in-situ observation/ sampling). Underlying SUIMON is a data management system to facilitate exchange of data and information. The overall aim of the network is to improve coordination strategies and instruments; to identify data gaps based on science and user driven requirements; and to intelligently combine observations from a variety of platforms by using a data assimilation system that is tuned to produce the best estimate of the current state of the urban atmosphere
Visualization of flood data using HTML5 technologies
Human civilization always used to settle near water sources, such as rivers, lakes and seas. But, beside the vast benefits that these regions offer, they sometimes present a huge threat of flooding the inhabited areas, when even the human life could be endangered. Thus, a systems that would offer an early information about the flood state of an endangered region is crucial for all the inhabitants, so they can base their quick actions on real and accurate data and not only on certain speculations. This paper presents a low cost solution that offers precise information about a flooded (or high risk) region using current web technologies. The system presents mapped data visualizations that show the position, the water level and the time of the last condition of multiple marked map points representing the flood sensors placement

Metroview-Sick Competition 2019
El proyecto fue llevado a cabo por un grupo multidisciplinar y multicultural de ingenieros cada uno de una disciplina y país distinto. Utilizamos técnicas de búsqueda y de Project Management durante todo el European Project Semester y el idioma común fue el inglés.
El proyecto se desarrolló de cara a participar en competición de innovación de la empresa SICK Inteligence. La empresa proporciona a los alumnos uno de sus sensores de última generación valorado en 8.000 € y ellos tienen que buscarle una aplicación innovadora y funcional además de una forma atractiva de comercializarlo.
El proyecto consistió en elaborar todas las fases de diseño de un nuevo producto además de crear un prototipo real para mostrar la idea seleccionada por el grupo.
Nos clasificamos entre los cinco finalistas entre todas las universidades de Finlandia con nuestra idea de usar el sensor para la seguridad en las estaciones de metro y presentamos la idea frente los altos cargos e ingenieros de SICK intelligence y obtuvimos un cheque de 1.000€.Departamento de Tecnología ElectrónicaGrado en Ingeniería en Organización Industria
