The WordPress.com stats helper monkeys prepared a 2013 annual report for this blog.

Here’s an excerpt:

The concert hall at the Sydney Opera House holds 2,700 people. This blog was viewed about 8,500 times in 2013. If it were a concert at Sydney Opera House, it would take about 3 sold-out performances for that many people to see it.

U.S. cracks open skies to testing, use of aerial drones

US-WEATHER-NASA-HURRICANE DRONES

 

NEW YORK (Reuters) – The U.S. aviation regulator took a step toward opening the skies to aerial drones on Monday, authorizing six sites where unmanned aircraft can be tested for a variety of uses.

The Federal Aviation Administration already has approved limited use of drones in the U.S. for law enforcement, surveillance, atmospheric research and other applications.

But Monday’s move will give companies, universities and other entities locations at which to test much broader use, such as crop spraying, catching exotic-animal poachers or delivering packages.

“It provides the platform for this research to be carried out on a very large scale across the country,” Federal Aviation Administration Administrator Michael Huerta told reporters.

The first test site is expected to be open in six months and the sites will operate at least until February 2017.

The FAA said the test sites will be developed by the University of Alaska, the state of Nevada, Griffiss International Airport in New York state, the North Dakota Department of Commerce, Texas A&M University at Corpus Christi, and Virginia Polytechnic Institute and State University, which includes locations in New Jersey.

The FAA is required to write initial rules governing commercial operation of drones by 2015. The test sites will operate longer, allowing rules to evolve with further testing, Huerta said.

Drones are smaller and less costly alternatives to manned aircraft, and are a growing business for aerospace companies such as Boeing Co, Northrop Grumman Corp, Lockheed Martin Corp and AeroVironment Inc.

Beyond military capabilities, they also offer uses to businesses and researchers. Amazon.com Inc recently unveiled plans for drones to deliver small packages to homes.

Global spending on unmanned aircraft will almost double to $11.6 billion a year by 2023, according to the latest estimate by aviation and aerospace industry research firm Teal Group.

The Association for Unmanned Vehicle Systems International (AUVSI), an industry group, estimates the industry could contribute more than $80 billion to the U.S. economy over a decade and create more than 100,000 jobs.

But the vehicles also have raised privacy and safety concerns, since they could be used for spying or could interfere with already crowded airspace.

The FAA chose the six sites from 25 applications it received from 24 states.

“These test sites will give us valuable information about how best to ensure the safe introduction of this advanced technology into our nation’s skies,” Transportation Secretary Anthony Foxx said in a statement.

Huerta said the FAA would first address the use of drones in small civil applications and expected to issue a proposed rule in early 2014.

Imagen foto_00000001Durante los días 18 y 19 de noviembre del presente año, en el marco del proyecto MECESUP UTA 1102 “Especialización interactiva y práctica de los estudiantes de la Carrera de Agronomía de la Universidad de Tarapacá, para el mejoramiento del desempeño laboral en el área de riego y fertirrigación como eje principal de una agricultura sustentable”, la Universidad de Tarapacá conto con la visita del Dr. Sigfredo Fuentes delDepartment of Agriculture and Food Systems, Melbourne School of Land & Environment University of Melbourne y MEMBER OF THE VINEYARD OF THE FUTURE (VoF) INITIATIVE, Australia.

El Dr. Fuentes, es ingeniero agrónomo de la Universidad de Talca, Chile y Doctor of Philosophy(PhD) at the Centrefor Plantand Food Science(PaFS), University of Western Sydney, Australia en Fisiología de Plantas y Riego, con mas de 40 publicaciones ISI. Durante su visita, dictó varias charlas para estudiantes en la Facultad de Ciencias Agronómicas de nuestra universidad, basada en los efectos del cambio climático en la agricultura y las nuevas y emergentes tecnologías para la investigación y adaptación a estos efectos. Destacando la utilización de drones (controladores de vuelos no tripulados y automatización para la toma de datos) llamados multicopters, cámaras infrarrojas y cámaras multiespectrales.

Gracias a su experiencia de trabajo en Australia, el Dr. Fuentes explico a los alumnos cómo en ese país han optimizado el riego para fines agrícolas, con el fin de ser más eficientes en el uso del agua y así mitigar la escasez de agua producto del cambio climático que esta sufriendo ese país. Además, presentó las nuevas tecnologías utilizadas hoy en día para monitorear el estado fisiológico de las plantas y el estado hídrico del suelo, ambos a tiempo reales. Todo esto, se realiza como se menciona anteriormente, mediante el uso de multicopters, para obtener los datos de los sensores de humedad de suelo, sensores instalados en las plantas, imágenes satelitales, estaciones meteorológicas, fotos infrarrojas cercanas y lejanas, entre otras. Con esta charla, los alumnos de la carrera de agronomía de la Universidad de Tarapacá, conocieron otra realidad, y las tecnologías de punta en Australia y a nivel mundial, toman medidas para mitigar los efectos del calentamiento global, siempre ligados al ámbito agrícola. Es importante considerar, que el grupo de trabajo del Dr. Fuentes, esta utilizando técnicas que puedan ser accesible, especialmente, con los sistemas de teléfonos celulares para medir el índice foliar, obtener fotografías para subirlas a plataformas de sistemas espectrales y así, evaluar el estado hídrico de las plantas, pero a nivel de extensiones grande de cultivos. En este ámbito, se esta redactando proyecto FONDEF IDEASen conjuntocon la Universidad de Talca (CITRA), Universidad de Melbourne y la Universidad de Tarapacá, para comenzar verdadera cooperación entre las universidades y firmar los convenios respectivos.

The Australian wine industry contributes strongly to the country’s economy (Lin, 2013). Australia is the sixth largest wine producer and the fourth largest wine exporter (WFA, 2013). Sparkling wine accounts for approximately 9% of the domestic wine sales and 13% of total wine imports in Australia (ABS, 2013). Wines with dissolved carbon dioxide are also economically important for several countries, France, Spain, Italy, USA, and Chile (IWSR, 2011; CIVC, 2013). Increase in temperature and carbon dioxide levels in the atmosphere have shown to affect flavour and aroma of wines (Johnson and Robinson, 2013), decrease protein concentration in plants (Högy et al., 2009; Azam et al., 2013; Mishra et al., 2013) and increase alcohol in wines (Howden and Stokes, 2009). Consequently, climate change is expected to influence the final quality of sparkling wine, since several compounds, including protein concentration and alcohol are related to foam stability and the ability of the wine to produce foam (Pozo-Bayón et al., 2009; Coelho et al., 2011).

Figure 3: Sparkling wine pouring

The quality of sparkling wine is visually assessed by its colour, bubble behaviour, appearance (bead) and foam persistence (mousse) (Liger-Belair, 2013). However, as discussed by a number of authors, these parameters are extremely variable and are affected by pouring, reception vessel shape and type as well as temperature (Cilindre et al., 2010; Liger-Belair et al., 2012; Liger-Belair et al., 2013). Robotics and chemometrics allows us to control and monitor these parameters, and thus repeatedly measure sparkling wine for quality assessment and to correlate it with traditional measures of quality. A robotic bottle pourer has been developed to standardise time and wine volume of pouring into a standardised vessel. Images are collected automatically with a digital camera attached to the pourer and transferred to a computer. These images are then evaluated by image analysis algorithms, which convey the information into bubble size and speed, foamability (ability of the wine to produce foam), foam persistence and stability, and collar stability.

As a result, this robotic pourer and image analysis algorithms, which simultaneously quantify both bubble’s individual behaviour and collectively as part of the foam, allows the development of a reproducible, easy and inexpensive method to measure sparkling wine quality. Results from this novel technology have been compared to chemometrics and sensory panel data using multivariate data analysis.

The MSLE with the Department of Mechanical Engineering from The University of Melbourne are developing customised unmanned aerial vehicles (UAVs) in the form of multicopters. The main aim of this project is to develop continuous remote monitoring systems to assess spatial and temporal variability of plant growth and water status, combined with a decision-making tool based on processed GIS maps (GIS-DMT). These tools will enable grapegrowers to apply efficient management strategies to maximise genetic cultivar potentials. Currently available methods to assess plant vigour and water status rely on expensive portable or fixed location instrumentation making the assessment of spatial and temporal variability of these parameters within a grapevine field difficult. Spatial variability can be obtained from airborne sensors and satellite imagery, which can be cost prohibitive and also have operational complexity in the information handling and data interpretation. Satellites also have a spatial resolution problem and long revisiting periods (low temporal resolution). Advances in miniaturised remote sensing technology (visual, infrared thermography and multispectral cameras) allow mounting them on UAVs and UTVs to assess plant vigour and water status using visible, multispectral and infrared thermal images. These systems are of high temporal and spatial resolution, which can be combined with GIS-DMT for rapid automated data analysis and reporting. The expected outcome would be management GIS maps of grapevine fields accessible to grapegrowers through a web page and specialised smartphone/tablet PC App. This integrated tool will offer competitive advantages to the Australian wine industry at a reduced cost compared to other available technologies.

The use of dogs for detection is nothing new. Dogs are used in a range of different detection endeavours including detecting drugs, explosives, ores and minerals, insect pests and cancer to name a few (Yinon, 1999; Furton and Myers, 2001; Bhadra, 2011). A dog’s olfactory cortex is 40 times larger than a humans and enables them to detect concentrations nearly 100 million times lower than humans. Dogs are able to recall isolated scents and can “store” scent in a nasal pocket created by a bony subethmoidal shelf. This nasal pocket permits odour molecules that are unrecognizable in a single sniff to accumulate and interact with olfactory receptors.

Early detection of pests and diseases in grapevines is vital to enable more effective control or eradication before symptoms occur or disease spreads. This project aims to train dogs to seek out and indicate the presence of three target odours; Brettanomyces, Eutypa lata and Phylloxera (Daktulosphaira vitifoliae). Determining firstly the ability of the dogs to detect the odour and secondly to assess reliability and thresholds for detection of that target odour. Six dogs of various breeds are currently being used for this project. Once trained, a dog can be switched from one scent to another relatively quickly. There are a large number of possibilities for use in the winery and vineyard. A properly trained dog can be more reliable than many current forms of detection, however one of the main reasons for this project is to ascertain the presence of odours for the potential for use of an electronic nose & chemosensors.
