Assessment of Regional Site-Specific Sorghum Ergot Severity Potential Using Radar-Rainfall Measurement

Sorghum ergot, caused by Claviceps africana, generally requires cool weather and humid conditions for optimum infection. Rainfall reportedly is not required for infection as long as relative humidity is high. However, occurrence of high humidity in the Texas Panhandle during the summer is usually associated with rain showers, and ergot incidence in the region has been observed to be associated with rain events. These events are often irregular and can vary within a small area both in incidence and intensity. Existing ground weather stations are too far apart to provide accurate representation of localized rainfall events. Radar-based precipitation measurements have a resolution of 4 × 4 km out to 230 km from the radar location. In the present study, radar rainfall measurements were used to assess regional site-specific sorghum ergot potential in the Texas Panhandle. The results have a potential for development of a web-based ergot risk assessment system in which growers can enter the GPS locations of their fields and determine whether management actions are necessary.

English Instruction

CSIEC (Computer Simulation in Educational Communication), is not only an intelligent web-based human-computer dialogue system with natural language for English instruction, but also a learning assessment system for learners and teachers. Its multiple functions—including grammar-based gap filling exercises, scenario show, free chatting and chatting on a given topic—can satisfy the various requirements for students with different backgrounds and learning abilities. After a brief explanation of the conception of our dialogue system, as well as a survey of related works, we will illustrate the system structure, and describe its pedagogical functions with the underlying AI techniques in detail such as NLP and rule-based reasoning. We will summarize the free Internet usage within a six month period and its integration into English classes in universities and middle schools. The evaluation findings about the class integration show that the chatting function has been improved and frequently utilized by the users, and the application of the CSIEC system on English instruction can motivate the learners to practice English and enhance their learning process. Finally, we will conclude with potential improvements.

Abstract. Precipitation during the monsoon season over the Indian subcontinent occurs in form of enormously complex spatiotemporal patterns due to the underlying dynamics of atmospheric circulation and varying topography. Employing methods from nonlinear time series analysis, we study spatial structures of the rainfall field during the summer monsoon and identify principle regions where the dynamics of monsoonal rainfall is more coherent or homogenous. Moreover, we estimate the time delay patterns of rain events. Here we present an analysis of two separate high resolution gridded data sets of daily rainfall covering the Indian subcontinent. Using the method of event synchronization (ES), we estimate regions where heavy rain events during monsoon happen in some lag synchronised form. Further using the delay behaviour of rainfall events, we estimate the directionalities related to the progress of such type of rainfall events. The Active (break) phase of a monsoon is characterised by an increase(decrease) of rainfall over certain regions of the Indian subcontinent. We show that our method is able to identify regions of such coherent rainfall activity.

In the world of information technology has changed the lifestyle in the aspect of our lives especially in the educational world. E-Raport is an academic information system used to input web-based student value data. The current value data input system is a benchmark for the creation of quality output and able to compete with other schools. One of the benchmarks that can be the competitiveness for other schools is the result of student learning assessments that are handled by each class. Problems that occur in the input of the value of Raport at SDN Sukanagara is currently still a manual that is the value of Raport recorded in the book Raport, so it takes a long time and a lot of energy needed. Research has the purpose of designing a value information system that facilitates the checking, recording and reporting of the computerized value of the students. Computerized Raport value reports can minimize errors in student data processing. This WEB based online raport is very easy data information and can be accessed anytime and anywhere, the system design works to insert and save value Report data and attendance and display info from school. The system uses data collection methods such as interviews, library studies, and system design, which are context diagrams, and prototypes. The information system of online Raport SDN Sukanagara is expected to be able to bring positive impact to the educational world, especially for SDN Sukanagara in the development of information technology applied in the world of education.

Abstract. This study presents an easy and convenient empirical method to optimize polarimetric variables and produce more accurate dual polarization radar rainfall estimation. Weather Radar Center (WRC) in Korea Meteorological Administration (KMA) suggested relations between polarimetric variables (Z–ZDR and Z–KDP) based on a 2-D Video Distrometer (2DVD) measurements in 2014. Observed polarimetric variables from CAPPI (Constant Altitude Plan Position Indicator) images composed at 1 km of height were adjusted using the WRC's relations. Then dual polarization radar rainfalls were estimated by six different radar rainfall estimation algorithms, which are using either Z, Z and ZDR, or Z, ZDR and KDP. Accuracy of radar rainfall estimations derived by the six algorithms using the adjusted variables was assessed through comparison with raingauge observations. As a result, the accuracy of the radar rainfall estimation using adjusted polarimetric variables has improved from 50 % to 70 % approximately. Three high rainfall events with more than 40 mm of maximum hourly rainfall were shown the best accuracy on the rainfall estimation derived by using Z, ZDR and KDP. Meanwhile stratiform event was gained better radar rainfalls estimated by algorithms using Z and ZDR.

Urban sprawl and the related landscape fragmentation is a Europe-wide challenge in the context of sustainable urban planning. The URBan land recycling Information services for Sustainable cities (URBIS) project aims for the development, implementation, and validation of web-based information services for urban vacant land in European functional urban areas in order to provide end-users with site specific characteristics and to facilitate the identification and evaluation of potential development areas. The URBIS services are developed based on open geospatial data. In particular, the Copernicus Urban Atlas thematic layers serve as the main data source for an initial inventory of sites. In combination with remotely sensed data like SPOT5 images and ancillary datasets like OpenStreetMap, detailed site specific information is extracted. Services are defined for three main categories: i) baseline services, which comprise an initial inventory and typology of urban land, ii) update services, which provide a regular inventory update as well as an analysis of urban land use dynamics and changes, and iii) thematic services, which deliver specific information tailored to end-users' needs.

In October 2011, the coastal municipalities of North Myrtle Beach, Myrtle Beach, Surfside, and Horry County signed a resolution, under the aegis of their Coastal Alliance of mayors, to develop and implement the Long Bay Hypoxia Monitoring Consortium. The goal of this consortium is to support monitoring and studies that further characterize hypoxia and its causes in Long Bay. The baseline data will enable assessments of water quality management efforts. Monitoring stations are to be maintained at three piers, Cherry Grove (NMB), Apache (Horry County), and Second Ave N. Pier (Myrtle Beach). Turbidity and chlorophyll sensors will be deployed at two piers and radon detectors at three piers. All piers will have weather stations. Data will be accessible via a real-time public website. Biological responses to low dissolved oxygen (DO) will be assessed via monitoring of larval recruitment and net plankton. The S.C. Department of Natural Resources (SCDNR) is also conducting creel surveys at the piers. These efforts are being coordinated with a marine education outreach campaign that includes signage at the piers, presentations at pier events, and web-based content.
