AX-PET: A novel PET detector concept with full 3D reconstruction
2009
We describe the concept and first experimental tests of a novel 3D axial Positron Emission Tomography (PET) geometry. It allows for a new way of measuring the interaction point in the detector with very high precision. It is based on a matrix of long Lutetium-Yttrium OxyorthoSilicate (LYSO) crystals oriented in the axial direction, each coupled to one Geiger Mode Avalanche Photodiode (G-APD) array. To derive the axial coordinate, Wave Length Shifter (WLS) strips are mounted orthogonally and interleaved between the crystals. The light from the WLS strips is read by custom-made G-APDs. The weighted mean of the signals in the WLS strips has proven to give very precise axial resolution. The ach…
APPLICATION OF REAL-TIME POLYMERASE CHAIN REACTION FOR RAPID DETERMINATION OFSALMONELLAIN RESTAURANT FOODS
2008
Several foods have been identified as frequently or occasionally contaminated with Salmonella, such as eggs, raw milk and all raw foods of animal origin that may carry salmonella and other bacteria. Salmonellosis is the most common food-borne illness, but it is usually preventable according to the implementation of a food safety system that includes Hazard Analysis and Critical Control Point. In this study, 96 food samples of the University restaurant of Valencia (Spain) were divided into four groups: first course; main course; accompaniment; and dessert, and were analyzed simultaneously with classical and fluorogenic polymerase chain reaction microbiological analysis. Neither of the proced…
Measuring Illness Behavior in One Minute
2019
Abstract. The present study addresses shortcomings in previous psychometric research into the Scale for the Assessment of Illness Behavior (SAIB) and develops a short form, the SAIB-10. We used ant-colony optimization to construct a subset of items in an exploratory sample ( n = 1,187) and affirmed it in factor analysis in a confirmatory sample ( n = 1,208). We find excellent model fit and evidence for strict invariance across sex and age. As expected, there were associations with distressed personality, perceived social support, and mental health. Finally, we report normative values for usage by researchers and clinicians. In sum, the SAIB-10 is an economical measure of illness behavior a…
Developing a Tool Point Control Scheme for a Hydraulic Crane Using Interactive Real-time Dynamic Simulation
2010
This paper describes the implementation of an interactive real-time dynamic simulation model of a hydraulic crane. The user input to the model is given continuously via joystick and output is presented continuously in a 3D animation. Using this simulation model, a tool point control scheme is developed for the specific crane, considering the saturation phenomena of the system and practical implementation. This paper describes the implementation of an interactive real-time dynamic simulation model of a hydraulic crane. The user input to the model is given continuously via joystick and output is presented continuously in a 3D animation. Using this simulation model, a tool point control scheme…
CUSHAW3: Sensitive and Accurate Base-Space and Color-Space Short-Read Alignment with Hybrid Seeding
2014
The majority of next-generation sequencing short-reads can be properly aligned by leading aligners at high speed. However, the alignment quality can still be further improved, since usually not all reads can be correctly aligned to large genomes, such as the human genome, even for simulated data. Moreover, even slight improvements in this area are important but challenging, and usually require significantly more computational endeavor. In this paper, we present CUSHAW3, an open-source parallelized, sensitive and accurate short-read aligner for both base-space and color-space sequences. In this aligner, we have investigated a hybrid seeding approach to improve alignment quality, which incorp…
Educational Tools for Second Life: a handbook for educators in virtual worlds.
2010
As a result of two collective activities organised during the MUVEnation programme, we have produced a collection of educational tools for Second Life. This collection has been produced in two stages. First, back in September 2008, 33 partcipants in the introductory module worked together in groups for the identification of more than 100 tools used for teaching and learning in Second Life. Later, in March 2009, 55 education professionals (lecturers, researchers, learning technologists and teachers) have collected, tested and fully described more than 150 tools. The result of this collective work has been transformed into a book, published as an Open Educational Resource under CC licence by …
THE VALIDATION OF A SELF-ASSESSMENT TOOL FOR THE TEACHER'S PRACTICES THAT EMBRACES THE NEURO-EDUCATIONAL APPROACH
2021
This contribution intends to present a study and research path that, starting from the theoretical framework of neuro-education, has led to the identification of five indicators (transversal area, socio-emotional-affective area, cognitive area, linguistic-communicative area, praxico-motor) on the basis of which a neuro-evaluation tool for teachers was built and validated: Self-assessment questionnaire of neuro-didactic and educational practices for teachers. Neuroscientific research is offering numerous points of reflection-action on the functioning of the brain and on how to modify the teaching and the educational proposal to improve the performance and growth of the person. However, the p…
Seamless Learning Environments in Higher Education with Mobile Devices and Examples
2016
The use of seamless learning environments that have the potential to support lifelong learning anytime and anywhere has become a reality. In this sense, many educational institutions have started to consider introducing seamless learning environments into their programs. The aim of this study is to analyze how various educational university programs implement the design elements for seamless learning environments with mobile devices. For that purpose, three cases involved in a Finnish teaching development project are explored by conducting semi-structured interviews with key participants. The themes of the interviews were related to the theoretical background for (mobile) seamless learning …

Applied study on the rotational molding and processing technology of rotational molds
2021
Computer-aided manufacturing involves a set of computerized activities related to the preparation, launch and follow-up of manufacturing. Computer-aided manufacturing is a tool that allows the use of 3D models based on computer-aided design. This paper addresses the process of rotational formation, with an effective focus on the technology of processing a rotational mold using CAM simulation as a research method. In this sense, the right choice of CNC and cutting tools is essential. The use of numerically controlled machine tools and high-performance cutting tools reduces the number of operations. The manufacturing route realized is specific to the parts machining on numerical control machi…
