Efficiently provisioning the resources in a large computing domain like cloud is challenging due to uncertainty in resource demands and computation ability of the cloud resources. Inefficient provisioning of the resources leads to several issues in terms of the drop in Quality of Service (QoS), violation of Service Level Agreement (SLA), over-provisioning of resources, under-provisioning of resources and so on. The main objective of the paper is to formulate optimal resource provisioning policies by efficiently handling the uncertainties in the jobs and resources with the application of Neutrosophic Soft-Set (NSS) and Fuzzy Neutrosophic Soft-Set (FNSS). The performance of the proposed work compared to the existing fuzzy auto scaling work achieves the throughput of 80% with the learning rate of 75% on homogeneous and heterogeneous workloads by considering the RUBiS, RUBBoS, and Olio benchmark applications.
Introduction: Non-Suicidal Self-Injury (NSSI) is the deliberate injury to one’s own body intended to cause mental or physical harm to oneself. In view of the growing scale of the NSSI, especially among young people without identifying any other psychiatric disorders, the disorder was included in both DSM-5 and ICD10 as independent diagnostic entity. Many etiopathogenetic hypotheses and research tools assessing various aspects of NSSI have been developed.
The aim of the work is to present and discuss the most commonly used scales for NSSI assessment.
Method: A review of available literature was made using the databases Medline / PubMed, using the key words: “self injury”, “self-mutilation”, “non-suicidal,”, “NSSI”, “self-harm” and time descriptors: 2005-2017
Results: Available tools were divided into three groups: I- scale of self-assessment made by the patient, II- assessment made by the clinician, and III- auxiliary scale.
Conclusions: None of the available scales covers the complexity of the NSSI phenomenon. For the overall NSSI assessment, several NSSI assessment tools are suggested, taking into account both self-assessment scales and clinical evaluation.
Herein, we are reporting, for the first time, a microwave-assisted synthesis of lead iodide (PbI2) nanosheets (NSs) with codoping of Zn and Mn, confirmed by SEM/EDX. In the co-doping Mn concentration was kept at a constant level (i.e. 15 %) while Zn concentration was varied from 1 wt.% to 10 wt.%. The morphological analysis confirming presence of the dopant was done through SEM/EDX. The single phase and polytypic nature of NSs were established by XRD and FT-Raman examinations. Homogeneous doping of Mn and Zn in prepared PbI2 NSs was confirmed by SEM mapping analysis. The dielectric and electrical properties were measured by preparing a compact pellet of NSs at 49820 Pa pressure. The dielectric constant and electrical conductivity were enhanced by Zn:Mn co-doping in PbI2. The radiation activity was tested by cesium-137 (137Cs) radioactive source and its increase resulting from the doping was observed. The enhanced properties suggest that the prepared NSs may be useful in electro-optic and radiation detection device applications.
The development of the new National Security Strategy (NSS) of the Republic of Croatia, begun in November 2016, takes place in a radically different security environment compared to the first (and current) Croatian NSS published in 2002. This paper aims to provide incentives for potential adaptations to the approach and methodology used in Croatia’s NSS development, particularly in relation to hybrid warfare. Assuming that the hybrid adversary tends heavily to exploit the vulnerabilities of the targeted state and society, the paper addresses some of Croatia’s widely recognized weaknesses that should be taken into consideration in a threat assessment. As a conclusion, the paper proposes some recommendations, including the concept of societal resilience, related to ways to counter hybrid threats.
Accelerated corrosion testing is indispensable for material selection, quality control and both initial and residual life time prediction for bare and painted metallic, polymeric, adhesive and other materials in atmospheric exposure conditions. The best known Neutral Salt Spray (NSS) test provides unrealistic conditions and poor correlation to exposures in atmosphere. Modern cyclic accelerated corrosion tests include intermittent salt spray, wet and dry phases and eventually other technical phases. They are able to predict the material performance in service more correctly as documented on several examples. The use of NSS should thus be restricted for quality control.
The Irish Government is in the process of developing a National Planning Framework (NPF). This will replace the National Spatial Strategy for Ireland 2002-2020 (NSS). The NSS is generally considered to have been unsuccessful, mainly due to a lack of implementation driven by shortcomings in governance. This paper explores these shortcomings, and suggests ways to prevent similar difficulties with the NPF. The paper concludes that the political process needs to be at the heart of the preparation and adoption of the NPF. There is the danger that the NPF will fail if the political environment remains embedded in traditional approaches to planning across the state.
Two Tomato spotted wilt virus (TSWV) isolates H1 and H2 found in Hippeastrum hybridum plants were characterized based on biological, serological, and molecular properties. Virus isolates showed differences in symptom expression – H1 isolate displayed severe necrotic spots and patterns, whereas mild mosaic symptoms were observed on H2-infected H. hybridum plants. Both TSWV isolates showed comparable reactivity with TSWV-specific antibodies and they induced similar symptoms on herbaceous indicator plants, but some differences between these isolates were detected at the nucleotide sequence level of genomic S and M ssRNAs segment fragments. The nucleotide sequences encoding nucleocapsid (N) and nonstructural (NSs and NSm) proteins showed 98.2%, 97.5%, and 96.5% identity, respectively. Phylogenetic analysis of N and NSs sequences conducted for tested isolates and 31 TSWV isolates included for comparison revealed that H1 and H2 isolates fell into the same cluster and they were grouped together with isolates found previously in different vegetables, ornamentals, and weeds. When NSm ORF was analyzed, the tested isolates formed a separate cluster: H1 isolate showed the highest affinity with TSWV isolates infecting chrysanthemum and pepper plants, whereas H2 isolate was most closely related to other virus isolates found in sweet pepper and tomatoes. These results indicate that both isolates were reassortants between different virus isolates, and represented two novel genetic patterns of TSWV.
The present study aims at exploring the under-investigated interface between SA and L2 phonological development by assessing the impact of a 3-month SA programme on the pronunciation of a group of 23 Catalan/Spanish learners of English (NNSs) by means of phonetic measures and perceived FA measures. 6 native speakers (NS) in an exchange programme in Spain provided baseline data for comparison purposes. The participants were recorded performing a reading aloud task before (pre-test) and immediately after (post-test) the SA. Another group of 37 proficient non-native listeners, also bilingual in Catalan/Spanish and trained in English phonetics, assessed the NNS' speech samples for degree of FA. Phonetic measures consisted of pronunciation accuracy scores computed by counting pronunciation errors (phonemic deletions, insertions and substitutions, and stress misplacement). Measures of perceived FA were obtained with two experiments. In experiment 1, the listeners heard a random presentation of the sentences produced by the NSs and by the NNSs at pre-test and post-test and rated them on a 7-point Likert scale for degree of FA (1 = “native” , 7 = “heavy foreign accent”). In experiment 2, they heard paired pre-test/post-test sentences (i.e. produced by the same NNS at pre-test and posttest) and indicated which of the two sounded more native-like. Then, they stated their judgment confidence level on a 7-point scale (1 = “unsure”, 7 = “sure”). Results indicated a slight, non-significant improvement in perceived FA after SA. However, a significant decrease was found in pronunciation accuracy scores after SA. Measures of pronunciation accuracy and FA ratings were also found to be strongly correlated. These findings are discussed in light of the often reported mixed results as regards pronunciation improvement during short-term immersion.
