Efficient Cloud Gaming Resource Provision Via Multi-dimensional Bin-Packing
Get PDFIn order to enable the acceptable level of service quality for cloud gaming services, sufficient resources should be always maintained and optimal resource management is then necessary. However, taking only a limited set of server-related parameters, but ignoring the client-related parameters, in the typical formulation of optimization problem cannot yield for optimal resource allocation in the cloud gaming environment nowadays, where the game server’s computing processors can be driven by both the CPU and GPU, and the client devices’ display resolutions are largely heterogeneous. In this paper, we describe how better cloud gaming resource utilization can be achieved through a formulation of Multi-dimensional bin-packing optimization problem. Based on the experiment results, our proposed mechanism looks promising for realistic cloud gaming services, where the adaptive feature must be taken as a prime consideration for efficient cloud gaming resource management
Efficient Computation of Group Skyline Queries on MapReduce
Get PDFSkyline query is one of the important issues indatabase research and has been applied in diverse applicationsincluding multi-criteria decision support systems and so on. Theresponse of a skyline query eliminates unnecessary tuples andreturns only the user-interested result. Traditional skyline querypicks out the outstanding tuples, based on one-to-one recordcomparisons. Some modern applications request, beyond thesingular ones, for superior combinations of records. For example,fantasy basketball is composed of 5 players, fantasy baseball of 9players, and a hackathon of several programmers. Group skylineaims at considering all the groups comprising several records,and finding out the non-dominated ones. Because of the highcomplexity, few studies have been conducted and none has beenpresented in either distributed or parallel computing. This paperis the first study that solves the group skyline in the distributedMapReduce framework. We propose the MRGS algorithm togenerate all the combinations, compute the winners at each localnode, and find out the answer globally. We further propose theMRIGS algorithm to release the bottleneck of MRGS onunbalanced computing load of nodes. Finally, we propose theMRIGS-P algorithm to prune the impossible combinations andproduce indexed and balanced MapReduce computation.Extensive experiments with NBA datasets show that MRIGS-P is6 times faster than the MRGS algorithm
AHP-based Adaptive Resource Selection for Cognitive Platform in Cloud Gaming Service
Get PDFCloud gaming service enables offloading heavy video-processing tasks up to the cloud server so that simple computers or mobile devices can be eligible to run sophisticated games, but on the expense of high network communications. In this regard, the adequate network utilization must be realized for delivering good gaming experiences to the game players. This necessitates a cognitive platform, which is capable of modifying its multimedia quality requirement in response to the network constraint, and notifying the cloud gaming server for updating the corresponded workload. In this regard, the Analytic Hierarchy Process (AHP) method has been proposed to deploy at the cognitive platform for cloud gaming service to select an optimal resource allocation strategy that satisfies various multimedia requirements and energy-awareness. Experiment results can confirm that the proposed method is flexible to enhance the capability of cloud gaming service in term of more efficient cloud gaming resource utilization, particularly during heavy-congested periods, while players’ quality of gaming experience can be still maintained under the mandate of intelligent agent on the player devices
SUDDEN UNEXPECTED INFANT DEATHS INVESTIGATION IN THE MIDDLE EAST REQUIRING FURTHER ACTION
Get PDFUnlike Western countries, little information available about the impact of Sudden Unexpected Infant Death (SUID) in the Middle East (ME) countries where high risk factors are very common. A structured literature review was performed to explore Sudden Infant Death Syndrome (SIDS) incidence across various ME countries, and shied lights on challenges associated with SUID investigation. The study found that data available on SUID in ME is extremely limited, however, it appears that SUID is a significant problem, could be a leading cause of mortality among infants in ME. Alarming data that sudden infant death rates could be higher than it reported. For a range of reasons, many infant deaths are registered as 'cause unknown', with no associated autopsy report or other details. Barriers to SUID reporting are linked to the regions’ political systems, culture, and religion. Further action is extremely recommended to investigate cases of unexpected infant deaths

Get PDFBackground: Indonesia is one of country with thelargest incidence of tuberculosis (TB) in the world. Adherenceto treatment is a significant problem to be managed. Therefore,there needs to be an intervention model that focuses on theinteraction between the nurse and the patient.Purpose: The purpose of this study was to analyze theinfluence of an Adherence Improvement Model (AIM) onpulmonary TB patients in Indonesia.Methods: The study used pre-test, post-test quasiexperimentaldesign to compared several factors related totreatment adherence over a six month period in 2013. Theintervention group (n=50) consisted of pulmonary TB patientsfrom one hospital in Surabaya, while the comparison group(n=50) consisted of pulmonary TB patients from a regionalpublic hospital in East Java.Results: Results showed that in the intervention group, therewere significant improvements in knowledge about the diseaseand its treatment, motivation to continue with the medications,and treatment adherence when compared to the comparisongroup.Conclusion: In conclusion an improvement in treatmentadherence in patients with pulmonary TB can be achieved byimplementing the Adherence Improvement Model (AIM)
Visual Word Recognition Study on Bilingual Groups of Odisha
Get PDFThe current study examined how emotional and neutral words affected during visual word recognition task. The test is measured with two different bilingual groups; Group A (SO) Santali first language (L1), Odia second language (L2) and Group B (OS) Odia first language (L1), Santali second language (L2). These two groups are considered as subject of the experiment. The test was conducted  with two different languages (Santali and Odia).The multivariate ANOVA technique was used to analyze the data generated from experiment for two dependent variables namely, recognition accuracy (RA) and response latency (RL).The factors considered in the ANOVA are visual field (VF) (LVF- Left visual field, RVF- Right visual field), stimulus content (SC) (EW-emotional word, NW- neutral word), word type (WT) (SW- Santali word, OW- Odia word), and presentation mode (PM) (unilateral, bilateral). The result of this study show emotional stimuli were better recognized in LVF than RVF. Unilaterally presented words were significantly better recognized than bilaterally presented words.Â

The outcomes of the present studyindicate that there is a +VE (positive) relationship betweenperformance and higher salary of employees, moreover, the vitalmotivational factor has been found to be the annual salaryprogression in a public sector organization. From the results, theauthors suggests that the strategies for management ofperformance of employees can be devised according to the levelof motivation of the employees
The Role of Gatekeepers in Research: Learning from Reflexivity and Reflection
Get PDFResearch is now an integral part of everyday health, education and social science practice. These professions need to be responsive to meet the changing needs in light of evidence based research findings. Within this process, gatekeepers have a key role to ensure researchers gain access to potential participants and sites for research. Positive influences of the gatekeepers can be invaluable to the research process by facilitating the smooth running of research activity to completion. At times, gatekeeping can be problematic with researchers having limited or no access to sites. In this present study to recruit vulnerable adolescents, a number of gatekeepers denied, limited or delayed access to potential participants and sites despite ethical, professional and organizational approval. In response, the researchers incorporated learning tools to address challenges brought about by gatekeepers in this study and for improvements in future studies. Reflexivity was used during the study to critically review all aspects of the research process and retrospective reflection identified areas that worked well and those areas for improvement in future studies. In broad terms, a number of factors were found to influence the action of gatekeepers. This related to level of understanding about the research, communication issues, motivation issues and fear or anxiety about the outcome. One recurring issue seemed to relate to the sensitive nature of the study and the deeply held attitudes and values of the individual gatekeepers. Researchers need to engage and involve the gatekeeper/s early in the research process. Other positive influences include sharing of clear information with the purpose of the research, the gatekeeper being motivated with a positive attitude to research which is also supported within the gatekeeper’s environment. When these positive influences are not present then this can have a negative influence on research activity
Integrating Scientific Publication into an Applied Gaming Ecosystem
Get PDFThe European (EU)-based industry for non-leisuregames (so called Applied Games, AGs) is an emerging business. Assuch it is still fragmented and needs to achieve critical mass tocompete globally. Nevertheless, its growth potential is widelyrecognized and even suggested to exceed the growth potential ofthe leisure games market. The European project Realizing anApplied Gaming Ecosystem (RAGE) is aiming at supporting thischallenge. RAGE will help to seize these opportunities by makingavailable an interoperable set of advanced Applied Game (AG)technology assets, as well as proven practices of using such AGassets in various real-world contexts. As described in [1], RAGEwill finally provide a centralized access to a wide range of appliedgaming software modules, relevant information, knowledge andcommunity services, and related scientific documents, taxonomies,media, and educational resources within an online communityportal called the RAGE Ecosystem. Besides this, an integrationbetween the RAGE Ecosystem and relevant social networkinteraction spaces that arranges and facilitates collaboration thatunderlie Research and Development (R&D), as well as marketorientedinnovation and exploitation will be created in order tosupport community building, as well as collaborative assetexploitation of User Generated Contents (UGCs) of the RAGEEcosystem. In this paper, we will describe the integration of theScientific Publication Platform (SPP) Mendeley [2] into the RAGEEcosystem. This will allow for automating repetitive tasks,reducing errors, and speeding up time consuming tasks. On theother hand it will support information, UGC, and knowledgesharing, as well as persistency of social interaction threads withinSocial Networking Sites (SNSs) and Groupware Systems (GWSs)that are connected to the RAGE Ecosystem. The paper reviewsrelevant use cases and scenarios, as well as related authentication,access, and information integration challenges. In this way, on theone hand a qualitative evaluation regarding an optimal technicalintegration is facilitated while on the other hand designapproaches for supporting features of resulting user interfaces areinitiated
