Post-AGB candidates in LMC and SMC SALT spectra
2020
We selected a sample of post-AGB candidates in the Magellanic Clouds on the basis of their near- and mid-infrared colour characteristics. Fifteen of the most optically bright post-AGB candidates were observed with the South African Large Telescope in order to determine their stellar parameters and thus to validate or discriminate their nature as post-AGB objects in the Magellanic Clouds. The spectral types of absorption-line objects were estimated according to the MK classification, and effective temperatures were obtained by means of stellar atmosphere modelling. Emission-line objects were classified on the basis of the fluxes of the emission lines and the presence of the continuum. Out of…
Pulsating B and Be stars in the Small Magellanic Cloud
2008
Context: Stellar pulsations in main-sequence B-type stars are driven by the kappa-mechanism due to the Fe-group opacity bump. The current models do not predict the presence of instability strips in the B spectral domain at very low metallicities. As the metallicity of the SMC is lower than Z=0.005, it constitutes a very suitable object to test these predictions. Aims: The main objective is to investigate the existence of B-type pulsators at low metallicities, searching for short-term periodic variability in absorption-line B and Be stars in the SMC. The analysis has been performed in a sample of 313 B and Be stars with fundamental astrophysical parameters accurately determined from high-res…
Customer satisfaction in B2B cloud services
2013
Tutkimuksen tavoitteena on kirjallisuuskatsauksen kautta esitellä B2B-pilvipalveluiden asiakastyytyväisyyteen vaikuttavia seikkoja, ja kuinka näitä seikkoja tulisi ottaa huomioon asiakastyytyväisyyden parantamisessa. Tässä tutkimuksessa verkkopohjaiseen liiketoimintaan liittyvää asiakastyytyväisyyden tutkimusta käytettiin pohjana etsiessä asiakastyytyväisyyteen vaikuttavia seikkoja pilvipalveluissa. Tutkimuksessa vertaillaan asiakastyytyväisyyteen vaikuttavia seikkoja vertailemalla tyytyväisyyteen vaikuttavia seikkoja verkkopohjaisen liiketoiminnan, yritysliiketoiminnan (B2B) ja kolmen asiakastyytyväisyyden ja palvelun laadun mallin (American Customer Satisfaction Index, SERVQUAL and SaaS-Q…
Collision Avoidance with Potential Fields Based on Parallel Processing of 3D-Point Cloud Data on the GPU
2014
In this paper we present an experimental study on real-time collision avoidance with potential fields that are based on 3D point cloud data and processed on the Graphics Processing Unit (GPU). The virtual forces from the potential fields serve two purposes. First, they are used for changing the reference trajectory. Second they are projected to and applied on torque control level for generating according nullspace behavior together with a Cartesian impedance main control loop. The GPU algorithm creates a map representation that is quickly accessible. In addition, outliers and the robot structure are efficiently removed from the data, and the resolution of the representation can be easily ad…
Datos personales y Cloud Computing
2016
Póster presentado en el XV Workshop de Rebiun "Datos y Bibliotecas", celebrado en Castellón los días 29 y 30 de septiembre de 2016 Las bibliotecas Universitarias están recurriendo con más frecuencia a soluciones informáticas en la nube para seguir ofreciendo el mejor servicio a sus usuarios y, de paso, aprovecharse del ahorro en costes, escalabilidad y mejoras en la gestión de datos que ello supone. Estos servicios en la nube los suelen ofrecer grandes empresas internacionales que han construido complejas y robustas infraestructuras, muchas veces localizadas fuera del territorio de la UE, para ayudar a las bibliotecas a seleccionar, adquirir, procesar, conservar y difundir sus recursos. Per…
Cloud product capability assessment method
2015
Tutkimuksen tavoitteena on lisätä osaamista tuotehallintaan, miten IT-palveluhallinta- ja kokonaisarkkitehtuurimenetelmiä voidaan integroida pilvipalveluiden tuotteistamiseen. Tutkimuksen toisena tavoitteena on rakentaa uusi pilvipalveluiden kyvykkyyksien hallintamenetelmä, jonka avulla pilvipalveluiden tuotteistusta voidaan hallita ideasta markkinoille saamiseen asti. Uusi menetelmä on tarkoitettu tuote- ja projektipäälliköille sekä arkkitehdeille, jotka työskentelevät pilvipalveluiden kanssa. Pilvipalvelulle luodaan liiketoiminnan näkökulmasta uusi määritelmä, annetaan lyhyt esittely pilvipalveluiden tuotehallinnasta sekä määritellään tarve liiketoiminnan ketteryydelle. IT-näkökulmassa tu…
IoT -based adversarial attack's effect on cloud data platform services in a smart building context
2020
IoT sensors and sensor networks are widely employed in businesses. The common problem is a remarkable number of IoT device transactions are unencrypted. Lack of correctly implemented and robust defense leaves the organization's IoT devices vulnerable to numerous cyber threats, such as adversarial and man-in-the-middle attacks or malware infections. A perpetrator can utilize adversarial examples when attacking machine learning (ML) models, such as convolutional neural networks (CNN) or deep neural networks (DNN) used, e.g., in DaaS cloud data platform service of smart buildings. DaaS cloud data platform's function in this study is to connect data from multiple IoT sensors, databases, private…
Explaining organizational adoption of technology : the case of cloud platforms
2015
The internet of things (IOT) is a vision that represents a world of connected devices which are identifiable and may have capabilities to sense and act on the surrounding environment. Almost every item in the planet has the potential to become part of the IOT. The data exchange between these devices requires that cloud technologies are applied. These cloud computing platforms already exist and need to adapt to the specific needs of the IOT in order to cope with the high demands of the IOT, for example handling the Big Data generated by the IOT devices. Nonetheless, little is known about the adoption levels of these platforms. In the past the UTAUT2 has been used to help explain technology a…
