A Service Level Agreement Framework of Cloud Computing based on the Cloud Bank Model
No full textThe Cloud Bank model, which is derived from Grid bank [1], is a kind of commerce model of cloud computing that provides pay-as-you-go computing resources. In this model, Cloud Bank is an agent platform of resource transaction. Cloud computing uses the concept of service level agreement (S LA) to control the use and receipt of computing resources from, and by, Cloud Bank. As computing resources are provided in the form of services, Quality of Service (QoS) mechanisms are introduced to solve any quality of service problems. This paper presents a framework of Service Level Agreements in the Cloud Bank model (CBSLA), QoS attributes is added to the CBSLA to guarantee the quality of service. All the transactions of cloud bank are based on the CBSLA agreement

Previous issue date: 2019-12-11Several studies have shown that South America is one of the prime locations for the production of intense hailstorms in the world, with previous research showing South America to be a region of large hail production using TRMM and other satellite proxies. Until recently, there has been limited research on the hail production in Argentina due to a lack of consistent and quality-controlled observations, yet the damage from hail caused approximately 50 million USD in wine production losses annually.
This research utilizes Twitter to identify hail events, which are verified using GOES-13 satellite imagery and/or C-band radar signatures in Northern Argentina. ERA-5 reanalysis is then used to reconstruct the environment of giant hail (diameter > 70 mm) events. We found that areas surrounding Córdoba and Mendoza, Argentina have (1) enhanced synoptic-scale ascent through the overlapping of upper-level divergence from two jet streaks downstream of an anomalous trough; (2) a deep layer of moisture supplied from the Amazon basin transport by the South American low-level jet below mid-level cool, dry westerlies; and (3) composite CAPE > 1200 J/kg capped by CIN ~100 J/kg. Even though (1) and (2) are similar to the environment of hailstorms in the U.S., the relatively lower CAPE and higher CIN for giant hail production in Argentina poses interesting questions for future work.Submission published under a 24 month embargo labeled 'U of I Access', the embargo will last until 2021-12-01The student, Shaowen Chen, accepted the attached license on 2019-12-10 at 22:12.The student, Shaowen Chen, submitted this Thesis for approval on 2019-12-10 at 22:41.This Thesis was approved for publication on 2019-12-11 at 16:01.DSpace SAF Submission Ingestion Package generated from Vireo submission #14782 on 2020-02-28 at 17:24:22Embargo set by: Seth Robbins for item 113937

Critical Theory and Interaction Design
No full textClassic texts by thinkers from Althusser to Žižek alongside essays by leaders in interaction design and HCI show the relevance of critical theory to interaction design.
Why should interaction designers read critical theory? Critical theory is proving unexpectedly relevant to media and technology studies. The editors of this volume argue that reading critical theory—understood in the broadest sense, including but not limited to the Frankfurt School—can help designers do what they want to do; can teach wisdom itself; can provoke; and can introduce new ways of seeing. They illustrate their argument by presenting classic texts by thinkers in critical theory from Althusser to Žižek alongside essays in which leaders in interaction design and HCI describe the influence of the text on their work. For example, one contributor considers the relevance Umberto Eco's “Openness, Information, Communication” to digital content; another reads Walter Benjamin's “The Author as Producer” in terms of interface designers; and another reflects on the implications of Judith Butler's Gender Trouble for interaction design. The editors offer a substantive introduction that traces the various strands of critical theory.
Taken together, the essays show how critical theory and interaction design can inform each other, and how interaction design, drawing on critical theory, might contribute to our deepest needs for connection, competency, self-esteem, and wellbeing.

Investigating the Embodied Effect in Drivers’ Safe Headway Learning
No full textabstract: Safe headway learning plays a core role in driving education. Traditional safe headway education just use the oral and literal methods to educate drivers the concept of safe headway time, while with the limitation of combining drivers subject and situational domains for drivers to learn. This study investigated that whether using ego-moving metaphor to embody driver's self-awareness can help to solve this problem. This study used multiple treatments (ego-moving and time-moving instruction of safe time headway) and controls with pretest experimental design to investigate the embody self-awareness effect in a car-following task. Drivers (N=40) were asked to follow a lead car at a 2-seconds safe time headway. Results found that using embodied-based instructions in safe headway learning can help to improve driver's headway time accuracy and performance stability in the car-following task, which supports the hypothesis that using embodied-based instructions help to facilitate safe headway learning. However, there are still some issues needed to be solved using embodied-based instructions for the drivers' safe headway education. This study serves as a new method for the safe headway education while providing empirical evidence for the embodied theories and their applications.Dissertation/ThesisMasters Thesis Applied Psychology 201
Dynamic Resource Provisioning for an Interactive System
No full textIn a data centre, server clusters are typically used to provide the required processing capacity to provide acceptable response time performance to interactive applications. The workload of each application may be time-varying. Static allocation to meet peak demand is not an efficient usage of resources. Dynamic resource allocation, on the other hand, can result in efficient resource utilization while meeting the performance goals of individual applications.
In this thesis, we develop a new interactive system model where the number of logon users changes over time. Our objective is to obtain results that can be used to guide dynamic resource allocation decisions. We obtain approximate analytic results for the response time distribution at steady state for our model. Using numerical examples, we show that these results are acceptable in terms of estimating the steady state probabilities of the number of logon users. We also show by comparison with simulation that our results are acceptable in estimating the response time distribution under a variety of dynamic resource allocation scenarios. More importantly, we show that our results are accurate in terms of predicting the minimum number of processor nodes required to meet the performance goal of an interaction application. Such information is valuable to resource provisioning and we discuss how our results can be used to guide dynamic resource allocation decisions
Efecto de la aplicación de biocarbón de sarmientos sobre las propiedades fisicoquímicas de un suelo de vid
No full textSe realizó una experiencia de campo con transformación de sarmientos en biochar y
aplicación al suelo, en parcelas de viñedo con el fin de comprobar el interés de este
aprovechamiento de los residuos de poda y su efecto sobre el suelo. Se han tomado
muestras de suelo en marzo de 2020, así como en 2018 (un mes más tarde de la
aplicación del biochar).
Se estudiaron los efectos del aporte de biochar en propiedades fisicoquímicas del
suelo, con tres tipos de textura y a dos profundidades. Se determinó la facilidad de
penetración de una sonda (en 2020), densidad aparente, pH y contenidos de fósforo
asimilable Olsen y de nitratos.
El aporte de biochar aumentó la facilidad de penetración de la sonda, medida a dos
años de la aplicación, sin observarse cambios en la densidad aparente del suelo. Se
encontró un aumento de pH en el muestreo del año de aplicación, pero no a los dos
años. No se encontró un aumento significativo en la disponibilidad de fósforo, pero sí
en el contenido de nitrato en el año de aplicación.Grado en Enologí

L-amino acid oxidase from Naja atra venom activates and binds to human platelets
No full textAn L-amino acid oxidase (LAAO), NA-LAAO, was purified from the venom of Naja atra. Its N-terminal sequence shows great similarity with LAAOs from other snake venoms. NA-LAAO dose-dependently induced aggregation of washed human platelets. However, it had no activity on platelets in platelet-rich plasma. A low concentration of NA-LAAO greatly promoted the effect of hydrogen peroxide, whereas hydrogen peroxide itself had little activation effect on platelets. NA-LAAO induced tyrosine phosphorylation of a number of platelet proteins including Src kinase, spleen tyrosine kinase, and phospholipase Cgamma2. Unlike convulxin, Fc receptor gamma chain and T lymphocyte adapter protein are not phosphorylated in NA-LAAO-activated platelets, suggesting an activation mechanism different from the glycoprotein VI pathway. Catalase inhibited the platelet aggregation and platelet protein phosphorylation induced by NA-LAAO. NA-LAAO bound to fixed platelets as well as to platelet lysates of Western blots. Furthermore, affinity chromatography of platelet proteins on an NA-LAAO-Sepharose 4B column isolated a few platelet membrane proteins, suggesting that binding of NA-LAAO to the platelet membrane might play a role in its action on platelets
