Enhanced channel estimation techniques for pilot assisted OFDMA systems.

Generalised orthogonal frequency-division multiple-access (OFDMA) has been one of key air-interfaces for next-generation mobile communication systems. Allocated pilot symbols play a key role for the channel estimation and prediction that is essential for the design of OFDMA transceivers. In the past years, pilot-assisted channel estimation (PACE) has received extensive investigations particularly for the downlink. Many classical PACE schemes have been developed together with the pilot optimisation that minimises the noise-induced channel estimation error. However, in uplink communications, where polynomial interpolation schemes are usually employed, the interpolation error induced by the mismatch between interpolation models and actual channels often exists besides the noise-induced error. Conventional PACE approaches assume that the interpolation-error can be ignored. However, throughout the investigation of this thesis, it was found the interpolation error could not be compensated by increasing signal-to-noise-ratio (SNR), meanwhile it could be the dominative factor to affect the PACE performance in high-SNR or high-mobility environments. Therefore, investigation for uplink PACE by considering the interpolation error becomes an interesting issue, and it is addressed from the following two aspects in this thesis: First, it was found that interpolation errors could be minimised via pilot placement optimisation. Therefore, the optimum pilot placement for OFDMA uplink was investigated for chunk-based systems, where linear interpolation is often employed for PACE. Two interesting results were further found: 1. the pilot placement minimising the linear interpolation error is independent of channel environments under certain conditions; 2. the optimum pilot placement is a function of the SNR. However, the best SNR-independent pilot placement offering the near-optimum performance for practical systems were proposed. Second, the interpolation error can also be reduced by carefully designed interpolation algorithms. So, new PACE approaches that performed the linear interpolation for the amplitude and phase respectively were proposed. Another investigated issue in this thesis is the waste of channel-gain resource for OFDMA downlink when an OFDMA system is rich in pilots. In this scenario, an adaptive approach for joint placement of pilot and payload symbols was proposed to effectively improve the overall system performance with the pay of channel estimation performance. Key words: OFDMA, Chunk, Channel estimation, Interpolation error, Pilot placement, Link adaptation, Linear interpolation.
Looking beyond the stars: A description of text mining technique to extract latent dimensions from online product reviews

The purpose of this study is to contribute to the marketing literature and practice by describing a research methodology to identify latent dimensions of customer satisfaction in product reviews, and examining the relationship between these attributes and customer satisfaction. Previous research in product reviews has largely relied only on quantitative ratings, either stars or review score. Advanced techniques for text mining provide the opportunity to extract meaning from customer online reviews. By analyzing 51,110 online reviews for 1,610 restaurants via latent Dirichlet allocation, this study uncovers 30 latent dimensions that are determinants of customer satisfaction. Furthermore, this study developed measurements of sentiment and innovativeness as moderators of the effect of these latent attributes to satisfaction.

Psychological Resilience Enhances the Orbitofrontal Network in the Elderly With Mild Cognitive Impairment

Background: It has been suggested that maintaining the efficient organization of the brain’s functional connectivity (FC) supports neuroflexibility under neurogenerative stress. This study examined psychological resilience-related FC in 112 older adults with mild cognitive impairment (MCI). Methods: Using a resting-state functional magnetic resonance imaging (fMRI) approach, we investigated reorganization of the orbitofrontal gyrus (OFG)/amygdala (AMG)/hippocampus (HP)/parahippocampal gyrus (PHG) FC according to the different levels of resilience scale. Results: Compared with the low resilient group, the high resilient group had greater connectivity strengths between the left inferior OFG and right superior OFG (P < 0.05, Bonferroni corrected), between the right inferior OFG and left PHG (P < 0.05, Bonferroni corrected), and between the right middle OFG and left PHG (false discovery rate < 0.05). Conclusion: Psychological resilience may be associated with enhancement of the orbitofrontal network in the elderly with MCI.
Preparing Preservice School Counselors to Serve Students With Disabilities: A Case Study

Using a case study, researchers examined how preservice school counselors experienced course content and activities related to students with disabilities. Course content, activities, and pedagogical strategies were based on recommendations from counselor education scholars and Bandura’s model of self-efficacy. Aligned with case study research (Yin), researchers gathered and triangulated both quantitative and qualitative data, which revealed that participants reported an overarching positive experience, gaining knowledge and confidence and appreciating practical experiences regarding course content and activities specific to students with disabilities.
Correlated Resting-State Functional MRI Activity of Frontostriatal, Thalamic, Temporal, and Cerebellar Brain Regions Differentiates Stroke Survivors with High Compared to Low Depressive Symptom Scores

Background One in three survivors of stroke experience poststroke depression (PSD). PSD has been linked with poorer recovery of function and cognition, yet our understanding of potential mechanisms is currently limited. Alterations in resting-state functional MRI have been investigated to a limited extent. Fluctuations in low frequency signal are reported, but it is unknown if interactions are present between the level of depressive symptom score and intrinsic brain activity in varying brain regions. Objective To investigate potential interaction effects between whole-brain resting-state activity and depressive symptoms in stroke survivors with low and high levels of depressive symptoms. Methods A cross-sectional analysis of 63 stroke survivors who were assessed at 3 months poststroke for depression, using the Montgomery–Åsberg Depression Rating Scale (MÅDRS-SIGMA), and for brain activity using fMRI. A MÅDRS-SIGMA score of >8 was classified as high depressive symptoms. Fractional amplitude of frequency fluctuations (fALFF) data across three frequency bands (broadband, i.e., ~0.01–0.08; subbands, i.e., slow-5: ~0.01–0.027 Hz, slow-4: 0.027–0.07) was examined. Results Of the 63 stroke survivors, 38 were classified as “low-depressive symptoms” and 25 as “high depressive symptoms. ” Six had a past history of depression. We found interaction effects across frequency bands in several brain regions that differentiated the two groups. The broadband analysis revealed interaction effects in the left insula and the left superior temporal lobe. The subband analysis showed contrasting fALFF response between the two groups in the left thalamus, right caudate, and left cerebellum. Across the three frequency bands, we found contrasting fALFF response in areas within the fronto-limbic-thalamic network and cerebellum. Conclusions We provide evidence that fALFF is sensitive to changes in poststroke depressive symptom severity and implicates frontostriatal and cerebellar regions, consistent with previous studies. The use of multiband analysis could be an effective method to examine neural correlates of depression after stroke.

A Review on DTC-SVM Method with Back-to-Back Converter Connected to the Permanent Magnet Generator and Comparison with DTC in the Matrix Converter

In this paper, the direct torque control torque based on space vector modulation (DTC-SVM) for permanent magnet synchronous generator connected to the variable-speed wind power generation system will be discussed. One of the most widely used in industry to convert voltage converters, converters back to back due to the very good features it is used. The main use space vector modulation voltage source inverters and current source is 3-phase. DTC method reduces the limitations and complexity of operation, so the price is Replay torque and flux machines that caused the DTC-SVM method is an alternative to it. The possibility of over-voltage matrix converter there on both sides. In some methods, sampling frequency and high frequency is required in others. The space vector modulation method sampling frequency is far less Direct Torque Control solution is a matrix converter.
Sample average approximation for a two-echelon inventory system with service-level constraints

Abstract We propose a sample-average-approximation-based simulation optimisation approach for solving a two-echelon inventory problem containing a total cost objective function and multiple service-level constraints. Some necessary parameter settings and conditions are provided to achieve the stopping condition in practice and the convergence to the optimal solution. The approach takes into account the stochastic nature of the objective and constraint performance measures, and allows the customer demands to occur with a random size and all events to occur at random points in time (including the stochastic lead times). Experimental studies are performed to evaluate the efficiency of the developed algorithms and other existing solution approaches.
Building a workbench to improve sharing and reproducibility of MOOC experiments

This thesis improves sharing of code and reproducibility (SaR) in research for massive open online courses (MOOCs). Reproducibility is recreating an experiment by a different researcher. Science in general struggles with repro- ducibility. MOOC experiments often contain useful code that could be used by other researchers, but that code is oftentimes not shared with others. To improve SaR in MOOC research, this thesis first identifies the challenges MOOC sci- entists encounter when trying to share code and when making their experiments reproducible. Then, user interviews are performed to further understand MOOC research and to better understand the challenges identified earlier. A conceptual experimental workflow is designed and implemented in the form of a workbench. The workbench is then evaluated. The identified challenges based on literature with regards to SaR are: (1) Difficulty in selecting the right tools, (2) lack of a standardized workflow that en- ables reprodubility and (3) manual work required to enable reproducibility with- out a clear incentive to perform that work. From the user interviews, researchers indicate experiencing these same challenges. Based on these challenges, I pro- pose an experimental workflow that focuses on making research reproducible and on sharing code. This workflow is implemented in the form of a work- bench, where researchers can create and manage their MOOC experiments. This workbench allows for sharing code between researchers and is evaluated using a real-world data science task by three actual large-scale learning analytics re- searchers and a visiting volunteer researcher. The evaluation finds that the work- bench needs more work to be suitable for actual MOOC research use and that more researcher education is needed to improve sharing and reproducibility in MOOC research.
Space Efficient Data Structures and Algorithms in the Word-RAM Model

In this thesis we study space-efficient data structures for various combinatorial objects. We focus on succinct and compact data structures. Succinct data structures are data structures whose size is within the information theoretic lower bound plus a lower order term, whereas compact data structures are data structures whose size is a constant factor from the information theoretic lower bound. We start by discussing the compact representation of unlabeled permutations, where the goal is to store a permutation π if we are permitted to reassign the labels of the elements, while supporting the following query: given k and i compute π(i) quickly. We study this problem in several scenarios. In the first scenario the queries are answered by just examining the labels of the queried elements. In the second scenario we assign labels to the n elements from the label set {1, . , cn} where c ≥ 1 is a constant. In the third scenario we assign labels to the n elements from the label set {1, . , cn} where c is a constant and 0 < ε < 1. We give tight upper and lower bounds in all the three scenarios and we are able to answer queries in constant time independent of k. Finally, as an application we show how to improve the representation of general (labeled) permutations using our results. We then deviate from the general scheme of designing space-efficient data structures to designing space-efficient algorithms. We cover the problem of powering permutations in place. Given a permutation of n elements, stored as an array, we address the problem of replacing the permutation by its k power while using o(n) bits of extra storage. To this end, we first present an algorithm for inverting permutations that uses O(lg n) additional bits and runs in O(n lg n) worst case time. This result is then generalized to the situation in which the permutation is to be replaced by its k power. We present an algorithm whose worst case running time is O(n lg n) and uses O(lg n+min{k lg n, n}) additional bits. Next, we cover data structures for range reporting. In range reporting problems a set S of n points in R is preprocessed such that the following query can be efficiently computed. Given an axis-aligned box Q return an aggregate function over S ∩ Q. Range reporting problems have fundamental importance in computational geometry, and are interesting to study both for their optimality with respect to space and query time, and as tools employed to provide efficient solutions to various geometric problems. We start by presenting a data structure that answers multi-dimensional range mode queries that improves a result by Chan et al. Then we present succinct data structures for one dimensional approximate color counting, one dimensional approximate median reporting, and one dimensional color reporting.
Information creation and models of information behavior: Grounding synthesis and further research

This paper contributes to the conceptualization of information creation in the field of information behavior. To do so, it synthesizes discussions and conceptual models on information creation and related topics, such as communication, design and documentation, which to date have been disconnected. A number of models are discussed, as well as some of the strengths, weaknesses and unique contributions of each with respect to information creation. This discussion leads to a number of paths for further research, both conceptual and empirical, on information creation. In particular, one fruitful site for further research in information creation is art. Drawing on the ground-breaking work of Tidline, it is clear that art is informative, and that the activities involved in and surrounding the creation of art showcase the aspects of information creation that have been highlighted in theoretical models of information behavior. Further research should consider the information behavior involved in an artistic task from start to finish.
An evaluative study of reliability and validity of Grit 12 item scale in Indian Context

Background: Grit refers to determination to achieve long term goals of life despite of unfavorable and unavoidable circumstances. It is implicated as the energetic working to challenges, along with preserving efforts and interests over the time, in-spite of facing barriers, hardships, and failures in the way of progress. The construct of grit comprises of two dimensions: consistency of interestsand perseverance of effort. The grit scale by Duckworth, Peterson, Matthews, and Kelly (2007) is originally developed to measure grit among Ivy League undergraduates. In present study researcher made an attempt to explore whether this two-factor model of grit to Indian sample. Method: The alternative model of grit was tested by employing confirmatory factory analysis (CFA) in AMOS 19.0. For this purpose, maximum likelihood techniques were used. 530 senior secondary school students from Himachal Pradesh, Northern India, completed the 12- item survey of grit. Results: The confirmatory factor analysis of the grit revealed that the 12 item, two factor model of grit determines a good fit model on the Indian sample. The results revealed that the grit scale possesses a good psychometric property on Indian sample which is evident from calculated internal consistency and composite reliability. The results also revealed that the grit scale have a good construct validity, as calculated AVE of all the factor was 0.50. Conclusion: From the analysis it is evident that the grit scale possesses adequate psychometric properties in Indian sample. The instrument of grit can be considered as a unitary construct in the developing country like India.
Yes! Kissing Too… The Child Would Not Be Hurt in Any Way: Social Constructions of Child Sexual Abuse in the Ga Community in Ghana

The United Nations Convention on the Rights of the Child obligates nations to protect children from all forms of abuse including sexual. However, child sexual abuse is a complex phenomenon which is difficult to understand as a result of cultural reasons. In view of this, the programs, policies, and interventions put in place to curb the phenomenon of child sexual abuse globally can only be effective if they are relevant to the social and cultural setting within which it happens. This is an exploratory study that sought to investigate social constructions of child sexual abuse in the Ga community. The study uses qualitative research methods to collect data from 42 respondents via six focus group discussions across three selected towns in the Greater Accra Region of Ghana. The findings showed that sexual activities between adults and children that were regarded as acceptable did not constitute child sexual abuse. However, sexual behaviors between adults and children that were regarded as unacceptable were viewed as serious, hence, considered as sexual abuse. The findings of this study illustrate the need for appropriate cultural interventions in curbing the phenomenon of child sexual abuse in the Ga Community in Ghana.
Tarrant Launceston: Survey and excavation of a long barrow with secondary burial at Race Down.

In March 2003, it was noted that rabbit burrowing had uncovered possible human remains close to the centre of Race Down long barrow. In order to determine whether the bones were human and/or of forensic interest, the School of Conservation Sciences (now the Department of Archaeology, Anthropology & Forensic Science), Bournemouth University, carried out a limited investigation on behalf of Dorset Police and the landowner, Defence Estates. The spoil heap of the rabbit burrow was excavated and this process revealed other displaced human bones, including long bones. A human osteologist examined the recovered bones and determined that the burial was ancient. Based upon results of the initial investigation, Dorset Police concluded that, although the remains were human, they would not be carrying out a criminal investigation due to the antiquity of the remains. In March 2004, a small excavation team from Bournemouth University returned to the site to fully recover any in situ human remains, together with recording the burial context and stratigraphy. A wider topographic survey of the long barrow was also carried out. This paper reports on the results of this field survey and excavation.
