Assessing B.A.Bar Device as a Tool for Supporting Labour Integration of a Severely Affected Person with Autism Who Carries Out Classifying Tasks
2004
This paper describes the case research carried out to demonstrate the utility of a specific technical aid (adapted bar code reader) to train an adult with severe autism in the performance of a work task of classifying products in a shop. The individual with autism who participated in this research has a combination of difficulties (degree of 76 percent of disability and unable to learn to read and write) and abilities (being able to follow single verbal instructions). Positive results are expounded together with considerations about the desirable features of future products that would overcome the mere training process and also be useful for the final and real task in any working environmen…
Medical news aggregation and ranking of taking into account the user needs
2019
The purpose of this work is to develop an intelligent information system that is designed for aggregation and ranking of news taking into account the needs of the user. The online market for mass media and the needs of readers, the purpose of their searches and moments is not enough to find the news is analyzed. A conceptual model of the information aggression system and ranking of news that would enable presentation of the work of the future intellectual information system, to show its structure is constructed. The methods and means for implementation of the intellectual information system are selected. An online resource for aggregation and ranking of news, news feeds and flexible setting…
Clustering-Assisted 3D Beamforming for Throughput Maximization in mmWave Networks
2021
Beamforming schemes have been widely used to improve network throughput in 5G mmWave networks. However, 3D beamforming schemes have hereto not been investigated in this context. In this work, a cluster-assisted 3D beamforming scheme is proposed to optimize the downtilt angle for network coverage and throughput maximization. User Equipment (UEs) are clustered based on inter-user and the inter-cluster distances. The interference is accounted from the adjacent clusters and thus frequency resources can be assigned to the non-adjacent clusters. Optimal downtilt angles are obtained for every cluster to maximize the throughput while considering the interference from adjacent clusters. 3D beam patt…
EVpedia: a community web portal for extracellular vesicles research
2014
Abstract Motivation: Extracellular vesicles (EVs) are spherical bilayered proteolipids, harboring various bioactive molecules. Due to the complexity of the vesicular nomenclatures and components, online searches for EV-related publications and vesicular components are currently challenging. Results: We present an improved version of EVpedia, a public database for EVs research. This community web portal contains a database of publications and vesicular components, identification of orthologous vesicular components, bioinformatic tools and a personalized function. EVpedia includes 6879 publications, 172 080 vesicular components from 263 high-throughput datasets, and has been accessed more tha…
On the design of pervasive computing applications based on Bluetooth and a P2P concept
2006
As an example of implementing the pervasive computing, we developed an application framework to deploy an easy, spontaneous, and infrastructureless network. We selected the Bluetooth technology with the peer-to-peer (P2P) concept to develop an experimental application which enables peers to exchange their resources. Overall network architecture and the prototype application are presented. We selected a small test-bed and simulation to evaluate the overall performance and system behaviour. We measured and present our findings in term of the duration of inquiry procedure and the throughput, according to various experimental parameters such as physical distance between nodes and their speeds.
Bibliotecas versus librerías de grandes superficies comerciales : usuarios y clientes
2007
En este artículo se analiza la polémica que surgió en Estados Unidos en 1998 entre la pervivencia de la biblioteca tradicional y una nueva forma de entender la información en las librerías de las grandes superficies comerciales. Después de una breve historia del origen de las grandes librerías y su posterior integración en las grandes superficies comerciales se examina como ha influido en la biblioteca esta nueva práctica empresarial. Cómo pretende convertir al usuario en cliente y obligarle a pagar por determinados servicios bibliotecarios. Por último, reflexiona de la manera que la popularización del ordenador y la irrupción de Internet han reforzado el papel de la biblioteca como centro …
Evolution-Oriented User-Centric Data Warehouse
2011
Data warehouses tend to evolve, because of changes in data sources and business requirements of users. All these kinds of changes must be properly handled, therefore, data warehouse development is never-ending process. In this paper we propose the evolution-oriented user-centric data warehouse design, which on the one hand allows to manage data warehouse evolution automatically or semi-automatically, and on the other hand it provides users with the understandable, easy and transparent data analysis possibilities. The proposed approach supports versions of data warehouse schemata and data semantics.
Christianity and digital culture : analysis of users' experiences of the christian social networking site in Taiwan - Walei
2011
Social Networking Sites (SNSs) have been a popular phenomenon worldwide, while religion in Computer Mediated Communication (CMC) studies has gained more academic attention. Walei as a pioneering social networking site is founded by a group of Protestant Christians targeting at the youth in Taiwan, and it exemplifies religious application on the Internet. This thesis investigates what role such a website plays both for its users and against its competition, particularly in the non-Christian cultural context. Using online interviews with nine users of Walei, how the interactivity affects Christian users‟ religious identity and the impression of non-Christian users toward Christianity is explo…
Relationships among Bicycle Rider Behaviours, Anger, Aggression, and Crashes in Finland
2022
Riding a bicycle is increasingly encouraged as a sustainable transport solution, especially in urban areas. However, safety concerns, both perceived and actual, can significantly lower the willingness to ride among the population. To support cycling planning and policy in the double task of increasing the levels of cycling while mitigating crash risk, there is a need to better understand the behaviours and attitudes of bicycle riders. In this manuscript, we study a cohort of Finnish bicycle riders through four questionnaires, the Cycling Behaviour Questionnaire (CBQ), Cyclist Risk Perception and Regulation Scale (RPRS), Cyclist Anger Scale (CAS), and Cyclist Aggression Expression Inventory …
Reinvestigation of the synthesis and evaluation of [N-methyl-11C]vorozole, a radiotracer targeting cytochrome P450 aromatase
2009
Abstract Introduction We reinvestigated the synthesis of [ N -methyl- 11 C]vorozole, a radiotracer for aromatase, and discovered the presence of an N -methyl isomer which was not removed in the original purification method. Herein we report the preparation and positron emission tomography (PET) studies of pure [ N -methyl- 11 C]vorozole. Methods Norvorozole was alkylated with [ 11 C]methyl iodide as previously described and also with unlabeled methyl iodide. A high-performance liquid chromatography (HPLC) method was developed to separate the regioisomers. Nuclear magnetic resonance (NMR) spectroscopy ( 13 C and 2D-nuclear Overhauser effect spectroscopy NMR) was used to identify and assign s…
