    Back to the future: A fully automatic method for robust age progression

    Get PDF
    It has been shown that significant age difference between a probe and gallery face image can decrease the matching accuracy. If the face images can be normalized in age, there can be a huge impact on the face verification accuracy and thus many novel applications such as matching driver's license, passport and visa images with the real person's images can be effectively implemented. Face progression can address this issue by generating a face image for a specific age. Many researchers have attempted to address this problem focusing on predicting older faces from a younger face. In this paper, we propose a novel method for robust and automatic face progression in totally unconstrained conditions. Our method takes into account that faces belonging to the same age-groups share age patterns such as wrinkles while faces across different age-groups share some common patterns such as expressions and skin colors. Given training images of K different age-groups the proposed method learns to recover K low-rank age and one low-rank common components. These extracted components from the learning phase are used to progress an input face to younger as well as older ages in bidirectional fashion. Using standard datasets, we demonstrate that the proposed progression method outperforms state-of-the-art age progression methods and also improves matching accuracy in a face verification protocol that includes age progression

    Developmental research of sustainable technologies to minimise problematic road embankment settlements

    Challenging, problematic and non-uniform ground conditions are a night mare to geotechnical engineers tasked with the design and construction of buildings and transport infrastructure. These often suffer undesirable structural settlements. Designing within the current understanding of geotechnics; settlement in peat and organic soils need to be recognised to include the known “primary and secondary consolidation characteristics” and the lesser known “tertiary consolidation phase”. These eventually contribute cumulatively to the consequential uneven and hazardous “bumpy road” surfaces. Undulating flexible road pavements result primarily from the transference of the heavy self-weight of the embankment fill to yielding and non-uniform subgrade. The adoption of conventional design/repair methods such as pile, vertical drain, soil replacement and soil stabilisation are expensive and inappropriate in very soft ground conditions. These then lead to unjustifiably high and repetitive maintenance costs. There being no one quick fix solution for all; pragmatic research must necessarily identify the best/progressively improved practical and sustainable solution. A viable solution is to develop criteria and explore the concept of a “masonry arch bridge structure/lintel-column structure” and adopting sustainable materials through pragmatic searching for appropriate recyclable waste materials. This will lead to the basis for a sustainable, innovative, strong, stiff, permeable composite mat structure that can be used on soft and/or yielding ground conditions. Conceptual lightweight fill technology including the popularly used expanded polystyrene (EPS) and the innovative composite mats recently being developed by the research team are outlined

    A Formal Study of the Privacy Concerns in Biometric-Based Remote Authentication Schemes

    Get PDF
    With their increasing popularity in cryptosystems, biometrics have attracted more and more attention from the information security community. However, how to handle the relevant privacy concerns remains to be troublesome. In this paper, we propose a novel security model to formalize the privacy concerns in biometric-based remote authentication schemes. Our security model covers a number of practical privacy concerns such as identity privacy and transaction anonymity, which have not been formally considered in the literature. In addition, we propose a general biometric-based remote authentication scheme and prove its security in our security model

    Supercapacitors Based On Patronite-reduced Graphene Oxide Hybrids: Experimental And Theoretical Insights

    Get PDF
    Here we report the hydrothermal synthesis and detailed study on supercapacitor applications of a patronite hybrid, VS4/reduced graphene oxide, which showed an enhanced specific capacitance of similar to 877 F g(-1) at a current density of 0.5 A g(-1). In comparison to bare vanadium sulfide and reduced graphene oxide, the hybrid showed similar to 6 times and similar to 5 times higher value of specific capacitance, respectively. The obtained energy density (117 W h kg(-1)) and power density (20.65 kW kg(-1)) are comparable to those of other reported transition metal sulfides and their graphene hybrids. Theoretical calculations using density functional theory confirm an enhanced quantum capacitance of VS4/graphene composite systems, owing primarily to the shifting of the graphene Dirac cone relative to the band gap of VS4. The results infer that the hybrid has the potential to be used as a high performance supercapacitor electrode.3371887418881DST (Government of India)DST-SERB [SB/FTP/PS-065/2013]Conselho Nacional de Desenvolvimento CientĂ­fico e TecnolĂłgico (CNPq)Ramanujan Fellowship [SR/S2/RJN-21/2012]Department of Science and Technology (DST-SERB), Govt. of India [SR/S1/IC-04/2012]Interconnect Focus Center (MARCO program)State of New YorkNational Science Foundation (NSF) Integrative Graduate Education and Research Traineeship (IGERT) program [0333314]Indo-US Science and Technology Forum (IUSSTF) through a joint INDO-US centre grantMinistry of Human Resources Development (MHRD), India through a center of excellence gran

    Signal specific electric potential sensors for operation in noisy environments

    Get PDF
    Limitations on the performance of electric potential sensors are due to saturation caused by environmental electromagnetic noise. The work described involves tailoring the response of the sensors to reject the main components of the noise, thereby enhancing both the effective dynamic range and signal to noise. We show that by using real-time analogue signal processing it is possible to detect a human heartbeat at a distance of 40 cm from the front of a subject in an unshielded laboratory. This result has significant implications both for security sensing and biometric measurements in addition to the more obvious safety related applications

    Impact of remittances on economic growth in developing countries: The role of openness

    Get PDF
    The paper examines the empirical relationship between remittances and economic growth for a sample of 62 developing countries over the time period 1990–2014. Remittances seem to promote growth only in the ‘more open’ countries. That is because remittances are in themselves not sufficient for growth. The extent of the benefit depends on domestic institutions and macroeconomic environment in the receiving country. Unlike the ‘less open’ countries, ‘more open’ countries have better institutions and better financial markets to take advantage of the remittances income and channelise them into profitable investments which, in turn, accelerates the rate of economic growth in these countries.N/

    Promoting the importance of aquatic foods on human nutrition and public health under APART in Assam

    Get PDF
    One of the key activities (Deliverable 7) under the APART project is “Improving impact of aquaculture and beel fisheries on human Nutrition”. WorldFish with partners is supporting the implementation of this activity. This consolidated report summarizes all the work done by WorldFish and partners as part of deliverable 7. The project has developed and tested several Social Behavioural Change Communication (SBCC) resources (e.g. banners, leaflets, brochures, calendars, TV spots, and videos) to promote the consumption of aquatic foods by vulnerable communities, PLM, adolescent girls, and children by targeting relevant stakeholders (e.g. Integrated Child Development Services programs, District Social Welfare (DSW) field functionaries, Anganwadi workers, Village communities, primary health centres, and the general public). We have trained 597 trainers to spread the message on the role of aquatic foods. We conducted 36 cluster-level awareness programs where 1994 numbers of women, adolescent girls and community people were given information on the benefits of fish consumption. We also organised 2 zonal workshops and 1 statelevel workshop for different stakeholders to build awareness of the importance of aquatic foods. Based on the demonstrations at the community level, the project documented all the small fish-based recipes cooked locally at the community level and produced a Small Fish Recipes book

    Finance, Development, and Remittances: Extending the Scale of Accumulation in Migrant Labour Regimes

    Get PDF
    The last decade has seen a heightened level of interest in the relationship between remittances and development, driven by the World Bank and other Bretton Woods Institutions. This has materialised in a global agenda to incorporate migrants and their households in commercial banking. The double significance of this policy rests in the financial incorporation of migrants and their households, and in the deepening entrenchment of the historical labour migration dynamic between sending communities and centres of capital. The central role of labour power in the advance of money forms the core of this analysis of a contemporary market-building strategy. This article presents a threefold critique of the global remittance agenda, based on (1) its transformative profit-driven development ideology, (2) its detachment of remittances from the political economy of migrant labour regimes, and (3) its dismissal of existing modes of remitting and uses of the funds
