Gel de Clorhexidina intra-alveolar en la prevención de la alveolitis tras la extracción de terceros molares inferiores: Estudio piloto
2006
Purpose: Chlorhexidine is a good prophylactic agent for post-extraction dry socket alveolitis. The bio-adhesive 0.2% chlorhexidine gel could improve this action since its intra-alveolar positioning would allow a more direct action on the alveolus and more prolonged action of the medication. Materials and Method: We present a single blind, randomised study on 30 patients to evaluate the efficacy of the bio-adhesive 0.2% chlorhexidine gel, placed only once within the alveolus, on the reduction of the incidence of impacted third molar postextraction dry socket alveolitis and its post-operative effects on patients. Results. A reduction of 42.65% in the occurrence of alveolitis and a more favour…

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…
Multi-objective Optimization for Computation Offloading in Fog Computing
2018
Fog computing system is an emergent architecture for providing computing, storage, control, and networking capabilities for realizing Internet of Things. In the fog computing system, the mobile devices (MDs) can offload its data or computational expensive tasks to the fog node within its proximity, instead of distant cloud. Although offloading can reduce energy consumption at the MDs, it may also incur a larger execution delay including transmission time between the MDs and the fog/cloud servers, and waiting and execution time at the servers. Therefore, how to balance the energy consumption and delay performance is of research importance. Moreover, based on the energy consumption and delay,…
Pilvipohjaisten ERP -järjestelmien omaksumiseen vaikuttavia erikoispiirteitä
2016
Tämä pro gradu -tutkielma käsittelee pilvipohjaisten ERP -järjestelmien omaksumiseen liittyviä erikoispiirteitä. Pilvipohjaiset ERP -järjestelmät ovat osa 1960-luvulta alkanutta toiminnanohjausjärjestelmien luonnollista kehityskulkua. Viimeisen vuosikymmenen aikana nopeutuneet internetyhteydet ja muu internetpohjainen informaatioteknologia ovat synnyttänyt ilmiön, josta käytetään yleisesti termiä pilvilaskenta. Pilvilaskenta ja siihen liittyvät pilvipalvelut ovat esimerkki käynnissä olevasta digitalisaatiosta. Tutkielmassa esitetään tieteelliseen kirjallisuuteen sekä empiiriseen tutkimusaineistoon perustuen ERP -järjestelmien ja pilvilaskennan yhdistyessä syntyneiden pilvipohjaisen ERP -jär…
Pilvipalveluiden käyttö
2017
Tämä tutkielma perehtyy pilvipalveluihin, niiden käyttäjäryhmiin sekä syihin, miksi pilvipalveluita käytetään. Pilvipalvelut ovat internetin yli tarjottavia laitteita ja ohjelmistoja, joihin on samanaikainen pääsy eri puolilta maailmaa. Kaikilla on mahdollisuus hyödyntää pilvipalveluiden tuomia etuja niin teknisesti kuin taloudellisestikin. Mobiililaitteiden ja langattoman nettiyhteyden lisääntyvän suosion sekä koko ajan kasvavan datamäärän myötä myös pilvipalveluiden käyttö on laajentunut viime vuosina paljon. Pilvipalvelut tuovat paljon hyötyjä, jotka houkuttelevat lisää käyttäjiä. Toisaalta pilvipalveluiden varjopuolena on turvallisuus, joka mietityttää monia käyttäjiä. The usage of clou…
Quasi-periodical kinetic instabilities in minimum-B confined plasma
2022
We present the results of an experimental investigation of quasi-periodical kinetic instabilities exhibited by magnetically confined electron cyclotron resonance heated plasmas. The instabilities were detected by measuring plasma microwave emission, electron losses, and wall bremsstrahlung. The instabilities were found to be grouped into fast sequences of periodic plasma losses, separated by ∼100 µs between the bursts, followed by 1–10 ms quiescent periods before the next event. Increasing the plasma energy content by adjusting the plasma heating parameters, in particular the magnetic field strength, makes the instabilities more chaotic in the time domain. Statistical analysis reveals that …
Dynamic regimes of cyclotron instability in the afterglow mode of minimum-B electron cyclotron resonance ion source plasma
2016
The paper is concerned with the dynamic regimes of cyclotron instabilities in non-equilibrium plasma of a minimum-B electron cyclotron resonance ion source operated in pulsed mode. The instability appears in decaying ion source plasma shortly (1–10 ms) after switching off the microwave radiation of the klystron, and manifests itself in the form of powerful pulses of electromagnetic emission associated with precipitation of high-energy electrons along the magnetic field lines. Recently it was shown that this plasma instability causes perturbations of the extracted ion current, which limits the performance of the ion source and generates strong bursts of bremsstrahlung emission. In this artic…
Recent progress on the superconducting ion source VENUS.
2012
The 28 GHz Ion Source VENUS (versatile ECR for nuclear science) is back in operation after the superconducting sextupole leads were repaired and a fourth cryocooler was added. VENUS serves as an R&D device to explore the limits of electron cyclotron resonance source performance at 28 GHz with its 10 kW gryotron and optimum magnetic fields and as an ion source to increase the capabilities of the 88-Inch Cyclotron both for nuclear physics research and applications. The development and testing of ovens and sputtering techniques cover a wide range of applications. Recent experiments on bismuth demonstrated stable operation at 300 eμA of Bi31+, which is in the intensity range of interest for hig…
