UJI RobInLab's approach to the Amazon Robotics Challenge 2017
2017
This paper describes the approach taken by the team from the Robotic Intelligence Laboratory at Jaume I University to the Amazon Robotics Challenge 2017. The goal of the challenge is to automate pick and place operations in unstructured environments, specifically the shelves in an Amazon warehouse. RobInLab's approach is based on a Baxter Research robot and a customized storage system. The system's modular architecture, based on ROS, allows communication between two computers, two Arduinos and the Baxter. It integrates 9 hardware components along with 10 different algorithms to accomplish the pick and stow tasks. We describe the main components and pipelines of the system, along with some e…
Detection of algorithmically generated malicious domain names using masked N-grams
2019
Abstract Malware detection is a challenge that has increased in complexity in the last few years. A widely adopted strategy is to detect malware by means of analyzing network traffic, capturing the communications with their command and control (C&C) servers. However, some malware families have shifted to a stealthier communication strategy, since anti-malware companies maintain blacklists of known malicious locations. Instead of using static IP addresses or domain names, they algorithmically generate domain names that may host their C&C servers. Hence, blacklist approaches become ineffective since the number of domain names to block is large and varies from time to time. In this paper, we i…
Reliable diagnostics using wireless sensor networks
2019
International audience; Monitoring activities in industry may require the use of wireless sensor networks, for instance due to difficult access or hostile environment. But it is well known that this type of networks has various limitations like the amount of disposable energy. Indeed, once a sensor node exhausts its resources, it will be dropped from the network, stopping so to forward information about maybe relevant features towards the sink. This will result in broken links and data loss which impacts the diagnostic accuracy at the sink level. It is therefore important to keep the network's monitoring service as long as possible by preserving the energy held by the nodes. As packet trans…
Plädoyer für einen (berufs-) alltagstauglichen Begriff von Spiritualität
2021
Zusammenfassung Ein Blick auf die deutschsprachige Diskussion um Spiritual Care zeigt: Die Konzepte sind noch rar, die Grundlagen und Methoden spiritueller Kommunikation im Berufsalltag darstellen und entfalten. Dabei betonen so gut wie alle Stellungnahmen der Gesundheitsfachberufe die Wichtigkeit der Spiritualität in ihrer Arbeit. Der folgende Beitrag lenkt den Blick von der Metaebene der Diskussion um Spiritualität auf die Mikroebene der konkreten Situationen, die die Angehörigen der versorgenden Berufe in Krankenhaus, Altenheim und Palliative Care antreffen. In diesem Beitrag wird ein Begriff von Spiritualität vorgestellt, der nicht nur der Hochform dieser Dimension, sondern auch der im …
Biomonitoring and evaluation of permethrin uptake in forestry workers using permethrin-treated tick-proof pants.
2014
We conducted a randomized case-control trial to analyze uptake of the insecticide/arcaricide permethrin in wearers of permethrin-impregnated and non-impregnated pants in German forestry. Eighty-two male workers were each equipped for a 16-week period with permethrin-treated (test group) or with non-treated work pants (control group). Pants with or without lining to protect against cuts, obtained from two different distributors, were worn in each group. Urinary permethrin metabolite levels were measured by GC-MS/MS before, during and after wearing of the pants. Permethrin uptake was calculated using additional questionnaire data. In the control group, metabolite levels in the range of enviro…
New contribution to the knowledge of two species of culicids inhabiting a mountainous rural area of Spain: Aedes (Rusticoidus) refiki (Medschid, 1928…
2017
espanolEntre final de abril y principio de mayo de 2017, en un area de montana con altitudes superiores a 1.500 msnm, se capturaron dos especies de mosquitos (Diptera, Culicidae) poco comunes: Aedes (Rusticoidus) refiki y Aedes (Ochlerotatus) pullatus. Se recolectaron 626 ejemplares, con densidades larvarias mayoritarias de Ae. refiki (87%). Se describio una nueva asociacion larvaria entre ambas especies, hasta la fecha desconocida. Los culicidos se localizaron en un entorno habitualmente nevado en invierno, del Parque Natural del Alto Tajo (Guadalajara, Comunidad de CastillaLa Mancha) y en los Montes Universales (Teruel, Comunidad Auto- noma de Aragon). En consecuencia, se presentan como p…

Tillage intensity and pasture in rotation effectively shape soil microbial communities at a landscape scale
2018
International audience; Soil microorganisms are essential to agroecosystem functioning and services. Yet, we still lack information on which farming practices can effectively shape the soil microbial communities. The aim of this study was to identify the farming practices, which are most effective at positively or negatively modifying bacterial and fungal diversity while considering the soil environmental variation at a landscape scale. A long-term research study catchment (12 km2 ) representative of intensive mixed farming (livestock and crop) in Western Europe was investigated using a regular grid for soil sampling (n = 186). Farming systems on this landscape scale were described in terms…
The Bioactive Compounds and Antioxidant Activity of Food Products of Rhizophora stylosa Fruit (Coffee and Tea Mangrove)
2018
The objective of this study is to investigate the bioactive compounds and antioxidant activity of coffee and tea mangrove (locally known in Indonesia) produced from the fruit of Rhizophora stylosa. Furthermore, three raw materials of coffee mangrove were also investigated to clarify their potencies. The crude extracts of five samples were subjected to antioxidant assay using DPPH. The results show that the extract of tea mangrove has the strongest activity; then, it was successfully fractionated using different polarity of solvents and yielded acetone and methanol fractions that had high antioxidant activity. The acetone fraction was purified and gave fractions A1, A2, A3, A4, A5, and A6, b…
Effect of Jasonia glutinosa on immune and oxidative status of gilthead seabream (Sparus aurata L.).
2020
Jasonia glutinosa (rock-tea, RT) has numerous biological activities. In the present work, the beneficial effects of dietary RT on gilthead seabream (Sparus aurata L.) were studied. Fish fed experimental diets containing 0 (control), 10 or 30% of RT for 15 and 30 days. Samples from skin mucus, blood, head kidney, liver and gut were obtained at 15 and 30 days. The antioxidant properties from RT were analysed such as the antioxidant capacity and phenolic content. The heat shock protein 70 level (HSP70) and the total oxidized proteins were evaluated on skin mucus as stress markers. Immune parameters, both humoral (peroxidase activity, immunoglobulin M levels and complement activity) and cellula…
