Light field-based face liveness detection with convolutional neural networks

Abstract. Face recognition based-access systems have been used widely in security systems as the recognition accuracy can be quite high. However, these systems suffer from low robustness to spoofing attacks. To achieve a reliable security system, a well-defined face liveness detection technique is crucial. We present an approach for this problem by combining data of the light-field camera (LFC) and the convolutional neural networks in the detection process. The LFC can detect the depth of an object by a single shot, from which we derive meaningful features to distinguish the spoofing attack from the real face, through a single shot. We propose two features for liveness detection: the ray difference images and the microlens images. Experimental results based on a self-built light-field imaging database for three types of the spoofing attacks are presented. The experimental results show that the proposed system gives a lower average classification error (0.028) as compared with the method of using hand-crafted features and conventional imaging systems. In addition, the proposed system can be used to classify the type of the spoofing attack.
Image quality of energy-dependent approaches for x-ray angiography

Digital subtraction angiography (DSA) is an x-ray-based imaging method widely used for diagnosis and treatment of patients with vascular disease. This technique uses subtraction of images acquired before and after injection of an iodinated contrast agent to generate iodine-speci c images. While it is extremely successful at imaging structures that are near-stationary over a period of several seconds, motion artifacts can result in poor image quality with uncooperative patients and DSA is rarely used for coronary applications. Alternative methods of generating iodine-speci c images with reduced motion artifacts might exploit the energy-dependence of x-ray attenuation in a patient. This could be performed either by aquiring two or more post-injection images at di erent x-ray energies or from an analysis of the spectral shape of the transmitted spectrum. The rst method, which we call energy-subtraction angiography (ESA), was introduced as a dual-energy alternative to DSA over two decades ago but technological limitations of the time resulted in poor image quality. The second potential method, energy-resolved angiography (ERA), requires energy-resolving photon-counting (EPC) xray detectors that are under development in a number of laboratories. The goals of this thesis were to: 1) develop a method of comparing image quality in terms of signal-to-noise ratio (SNR) obtained using ESA and ERA with DSA assuming ideal instrumentation for each; 2) develop a method of describing performance and image quality that can be obtained in practice with photon-counting detectors, and; 3) assess the potential of ESA and ERA by comparing the available iodine SNR with that of DSA including the e ects of non-ideal detector performance. It is shown that using ideal instrumentation both ESA and ERA can provide iodine-speci c images with SNR equal to that of DSA. However, stochastic x-ray interaction and detection processes will degrade SNR obtained with ERA and ESA to a larger extent than DSA. Energy-resolved angiography will achieve near-ideal performance only with low detector electronic noise levels, high collection e ciency of secondary quanta liberated in the detector, and low Compton cross sections. It is concluded that, when these conditions are satsi ed, ESA and ERA can provide iodine SNR within 25% of that of DSA for the same patient entrance exposure, and therefore may provide alternatives to DSA in situations where motion artifacts are expected to result in compromised DSA procedures, such as in coronary applications. This could have important applications for subtraction imaging of the coronary arteries in the near future.
Psychological rehabilitation from sport injury: issues in training and development of chartered physiotherapists

Despite growing interest into the role of physiotherapists in providing psychological rehabilitation to athletes during sport injury, very little research exists outside North America, Australia, and New Zealand (e.g., Hemmings & Povey, 2002). Thus, the main purpose of this research was to explore the role of UK chartered physiotherapists in the process of psychological rehabilitation from sport injuries. This thesis consists of four studies. With the intention to gain further insights into the physiotherapists’ views on the psychological aspects of their work, study one used the Physiotherapists and Sport Psychology Questionnaire (PSPQ; Hemmings & Povey, 2002) in a national survey with 361 UK chartered physiotherapists working in sport medicine. The results from the survey provided useful insights into the ways in which psychological interventions are currently employed in rehabilitation physiotherapy. In study two, these findings were explored further, by developing a questionnaire survey to explore chartered physiotherapists’ (N = 22) preferred method of sport psychology intervention training. With the purpose of gaining an insight into the physiotherapists’ personal experiences in using psychological interventions with injured athletes, study three adopted a qualitative approach, in which semi-structured interviews were conducted with seven UK chartered physiotherapists. The findings from the Interpretative Phenomenological Analysis (IPA; Smith, 1996) provided deeper understanding on physiotherapists current knowledge on, and their past experiences and opinions on using range of psychological interventions in their work with injured athletes. Similarly study four used semi-structured interviews and IPA with ten athletes who had previously encountered moderate or severe sport injuries requiring physiotherapy treatment. The findings revealed useful information on the physiotherapists’ role in providing psychological support and using psychological interventions in their work with injured athletes. In conclusion, the research presented in this thesis makes a contribution to knowledge by: (a) providing an insight into the views of chartered physiotherapists in the UK on psychological content of their practice, (b) making preliminary suggestions into how further training in sport psychology for chartered physiotherapists could be delivered, (c) enabling deeper understanding of physiotherapists current practices and past experiences in utilising selected psychological interventions in their work, and (d) giving a voice to injured athletes with regard to the role of physiotherapists in providing psychological support during sport injury rehabilitation.
Awareness, attitude and practice of breast feeding among mothers at tertiary care center, Puducherry, India

Background: The knowledge and practice of exclusive breastfeeding has been prejudiced by demographic, social, cultural, biophysical, and psychosocial factors. About two-thirds of under-five deaths in India are associated with inappropriate infant feeding practices. Objective of this study was to assess the awareness, knowledge and practice of breastfeeding among the mothers attending to the tertiary care institute at Puducherry, India.Methods: This hospital-based, cross-sectional study was carried out among 150 postnatal mothers who attended immunization clinics, post-natal and paediatric wards at the tertiary care hospital at Puducherry collecting data about breastfeeding knowledge and practices using a structured interview.Results: The breastfeeding practices were significantly poorer in terms of initiation, feeding colostrums, timing and frequency of feeding and inclusion of pre-lacteal feeds among obese women compared to the normal weighted mothers. The breastfeeding knowledge and attitude was healthy among the mothers as depicted by the awareness of nutritive value of breast milk by majority (84%) of mothers.Conclusions: The mothers had poor knowledge regarding initiation of breastfeeding and administration of colostrum. There was a positive attitude about exclusive breastfeeding, frequency of feeding and social aspects of breastfeeding.

GENDER GAP IN JOB UTILITY OF BRITISH WORKERS

The gender gap in attaining a university qualification has gradually narrowed in Britain and this has motivated the evaluation of gender differences in non-pecuniary returns of education. Therefore, this paper explores the trends in job utility of workers, measured by subjective self-evaluation of satisfaction scores from work. The data shows that while female workers experience higher job utility compared to men during the survey period, male workers are reporting higher utility in recent years, resulting in narrowing gender gap in job utility. Logistic regression models are used to understand the factors contributing to this gender gap. The results suggest that education is unlikely to contribute to this trend whereas unemployment has a small contribution to the emerging pattern. Furthermore, the results show that job utility of male workers is more cyclically sensitive compared to female workers as stalling unemployment during an economic downturn affects men more than women.
The position of greater palatine foramen in the adult human skulls of North Indian origin.

Dentists and Anaesthetists anaesthetize greater palatine nerve at greater palatine foramen, to perform various surgeries on hard palate. But even standard textbooks of Anatomy mention the position of greater palatine foramen in a very general way. Considering the paucity of literature on exact location of greater palatine foramen in North Indians and its variable description in standard textbooks of anatomy and anaesthesiology, following study was felt necessary to be conducted. Various parameters in relation to greater palatine foramen were noted in one hundred adult human skulls of North Indian origin. The dentition was complete with full eruption of third molar teeth. Greater palatine foramen was medial to third molar in most of the skulls seen (47.5%). Greater palatine canal opened vertically downwards in majority of the skulls examined (93.5%). Generally, the palatal vault was “U” shaped. Posterior margin of the foramen was raised in more than 63% skulls.
TISSUE RESPONSE OF TYPE 2 DIABETICS TOWARDS NON-SURGICAL PERIODONTAL THERAPY: A RETROSPECTIVE, COMPARATIVE STUDY WITH NON-DIABETICS - A PRELIMINARY INVESTIGATION

The purpose of this study was to assess the tissue response of Type 2 diabetic subjects towards non surgical periodontal therapy as compared with matched, non-diabetic subjects. This was a retrospective, comparative study using periodontal case notes of 40 subjects attending undergraduates’ periodontal clinics (20 diabetics, 20 non-diabetics), who were selected based on the inclusion and exclusion criteria. Response towards non surgical periodontal therapy was assessed through three clinical periodontal parameters, namely plaque score, gingivitis score and number of periodontal pocket ≥5mm at the baseline and after initial non surgical periodontal therapy. Data obtained was then analyzed by SPSS Version 12. Both diabetic and non-diabetic subjects showed significant improvements (p-value = 0.021; 0.000; 0.001 and 0.010; 0.014; 0.001) in all three parameters after the therapy. However, when comparison was made between the two groups, there was no significant difference (p-value = 0.913; 0.892 and 0.903) in any of the parameters. Periodontal conditions improved clinically in both diabetic and non-diabetic subjects after non-surgical periodontal therapy. Therefore, both groups responded similarly towards the therapy and thus it can be postulated that well-controlled diabetic status does not have a significant effect on the outcome of periodontal therapy.
Reimaging the role of the information professionals in the Educational process: the case of the Sultanate of Oman

This research applied a mixed-approach to investigate professionals perceive on their profession and what others expect from them to lead professional organizations setting their core competencies for the future. Furthermore, the research aimed to explore LRCs observes their educational preparation and job practices in building their profession. Besides, it defines the critical restrictions that prohibit them from reimaging their future professional roles within the educational process. Questionnaires are used to explore Omani professionals acquired competencies from learning and work. In addition, the research conducted tow discussion sessions with 10 focus groups to support the quantitative data collected through questionnaires. The quantitative findings indicated that a weak correlation between educational programs and work practices, especially in tasks requiring specialized skills and competencies. The qualitative findings highlighted the Competencies acquired by the information professional from work which are public relations, research skills, and partnership, marketing services skills, dealing with technology, and ways of dealing with the beneficiary. Besides, the findings revealed skills needed by the learning resource specialists as training in updating developments in the field, English language. Negative School staff's view information profession as multifunction of tasks that are not directly attributed to their occupation as well as far from the LRC regulations. The lack of communication between information professionals and supervisors, the absence of the learning resource specialists at schools in the first cycle of the basic education, the weakness of maintenance of hardware and Internet in schools, incorrect Job Title which is LRC Resource Specialist, are challenges hindered Omani professionals to make improvements in their profession. Accordingly, findings present suggestions to improve the actual status.
Engineering success: Using problem-based learning to develop critical thinking and communication skills in a Chemical Engineering classroom

This paper discusses the implementation of a joint, end-of-term PBL exercise (a project lab) into our second-year chemical engineering curriculum at University of Toronto through two courses, Applied Chemistry Laboratory I (CHE204) and Communication (CHE299). The activity was designed to help students learn (i) research skills, (ii) how to select appropriate experiment techniques and equipment, (iii) how to design and conduct a research experiment, (iv) how to analyze real-world results, (v) how to communicate using a technical voice, (vi) how to work collaboratively in a group. Students were guided through the project with e-Learning modules, in-class active learning exercises, and written feedback, but were not provided with the type of detailed guidance typically provided in their LBL. Student feedback indicates that they are able to apply their learning from the activity to new contexts in a later assignment.
Free-Access Higher Education.

The purpose of this study was to describe the degree of accessibility of all higher education institutions in the country and to estimate the proportion of various ponulations living within commuting distance of those colleges judged Lasily accessible or free-access institutions. The main idea was to put together an analysis of educational resources and demographic characteristics as one additional way of judging how higher education serves the population. Chapter 1 discusses the new meaning of equal opportunity and the developments of the 1960's that affected college admissions. Chapter 2 describes the procedure with which the degree of accessibility of all colleges was rated with respect to selectivity and cost, and how each free-access college with an appropriate commuting radius was plotted on detailed state maps. Chapter 3 is concerned with the colleges themselves -how many and what types there are at each level of accessibility and where they are located. Chapter 4 describes the populations living within commuting distance of the free-access colleges. Chapter 5 describes the accessibility of higher educaticn in each state, and the implication of the state profiles are discussed in Chapter 6. Chapter 7 considers the problem of relevance and suggests a framework for improving relevant educational opportunity. The final chapter summarizes the study.

The Customer Value: A Bibliographical Review

The perceived customer value is a multi-faceted concept and there is a relationship between the elements that compose an offering and the subjective interpretation of individuals. Within the same product category, different components are more meaningful to customers and have a different influence on shaping their value perception. Identifying the elements of value and the components that are meaningful to customers in a given distribution context helps marketers to focus on the specific characteristics that a value offering should have, in order to be more effective and resonate with the largest number of customers in a target market.
Topical arnica and mucopolysaccharide polysulfate (hirudoid) to decrease bruising and pain associated with haemodialysis cannulation - related infiltration: a pilot study

ABSTRACT Background: Topical treatments such as Arnica cream and mucopolysaccharide polysulfuric acid (contained in Hirudoid cream) have been used to treat the bruising and pain arising from dialysis-related infiltrations. Aim: To undertake a randomised controlled pilot study comparing the efficacy of Arnica and Hirudoid creams in treating bruising and pain following post-needling infiltration. Methods: One dialysis centre of 40 patients over a 12-month period. Following infiltration, and at the five subsequent dialysis treatments, pain was measured using the Abbey pain scale and size of the bruise was recorded. Results: Eleven cases of infiltration were recorded consisting of seven males (64%) and four females (36%) who had a mean age of 78 years (SD=9). Access for eight patients was via arteriovenous fistula and for three patients via arteriovenous graft. Eight patients experienced bruising and two patients reported mild pain post-infiltration but there were no differences found between the effect of Arnica or Hirudoid in treating either symptom. Conclusion: This pilot study was unable to detect any differences in the effect of Arnica and Hirudoid on pain or bruising. The study demonstrated that a larger, multicentre trial would be required to power a study and that a non-interventional control group should be added.
A literature review of methods to detect fabricated survey data

This paper reviews literature dealing with the issue of detecting interviewers who falsify survey data. The most reliable method of detecting falsifiers is through face-to-face reinterviewing of survey participants. However, only a limited number of participants can usually be reinterviewed. A review of the present literature clearly indicates that reinterviewing is more effective if the reinterview sample is put together according to some indicators that might be based on metadata, survey data or interviewer characteristics. We examine existing literature with regard to the suitability of different types of indicators that have been used in this context.
