    Full Text Available India, the largest democratic country in the world, is marching ahead strongly on the growth and developmental front and is poised to be the leader in the market economy. This role creates and increases far greater responsibilities on us in ensuring that the benefit of the developmental cycle reaches each and every citizen of this country, including the able and the disabled ones. It has been enshrined in the Constitution of India to ensure equality, freedom, justice, and dignity of all individuals and implicitly mandates an inclusive society. With increase in consideration of quality parameters in all spheres of life including availability, access, and provision of comprehensive services to the disabled, it is pertinent to have a look on the contribution of government in keeping the aspiration and commitment towards common people. The article attempts to review the concept of rehabilitation for the disabled keeping a focus on the blind person, and list out the activities, programs/schemes, institutional structure and initiatives taken by the Government of India (GOI for the same and the incentives/benefits extended to blind persons. The article concludes by reiterating the importance of individual need assessment and mentioning new initiatives proposed on Low Vision services in the approved 11 th plan under National Programme for Control of Blindness (NPCB. The source of information has been annual reports, notification and the approved 11 th five-year plan of GOI, articles published with key words like rehabilitation, disability, assistive devices, low vision aids, and/or blind person through the mode of Internet. Annexure provides a list of selected institutions in the country offering Low Vision services compiled from various sources through personal communication and an approved list of training institutes under NPCB, GOI offering Low Vision training.

  3. Guiding Blind Pedestrians with a Personal Navigation System

    Science.gov (United States)

    Dodson, A. H.; Moon, G. V.; Moore, T.; Jones, D.

    With the assistance provided by the white cane or guide dog, most blind pedestrians can find their way to known destinations along familiar routes. Finding new or known destinations along unfamiliar routes is more challenging. Before such a journey is attempted, detailed instructions must be acquired. The difficulty of obtaining and then reliably following such instructions deters many blind pedestrians from travelling alone in unknown areas. This paper demonstrates a technological approach, by way of field trials, that supplements the existing aids and eliminates the need for sighted guides. The approach has the potential to offer greater independence to the blind person. The investigation suggests that the methodology used in personal navigation systems for the sighted is sub-optimal for guiding the blind pedestrian. Suitable extensions are introduced, and the results show the proposed methodology is efficient for guiding the blind individual to unknown destinations in the chosen field trial environment.

  4. Use of personal computing technology by deaf-blind individuals.

    Science.gov (United States)

    Zuckerman, D

    1984-10-01

    This paper describes a system that enables deaf-blind people to work with microcomputers. The system utilizes the International Morse Code as a general communication medium. The deaf-blind person "hears" Morse code via a vibrotactile device to "see" the computer's screen. This technique enables deaf-blind individuals to receive immediate feedback from their typing and to scan the screen. This makes it possible for them to use the keyboard and screen in the same way as do seeing persons. A side benefit is that it provides a means for deaf-blind people to communicate with the sighted through a common medium. The sighted person can see the screen while the deaf-blind person feels it. Hardware cost to equip a standard personal computer with this interface is negligible. Vibrotactile Morse code is particularly viable because it can be adapted for the individual's particular tactile sensitivities. Morse-encoded tactile communication fits well in a social facilitation context for learning. It is technologically simple and standard. This work can significantly improve the quality of life for deaf-blind individuals because it provides new opportunities for communication and vocation. PMID:6239896

    Vision is the key sensory system in humans, leading to the implicit assumption that the acquisition of spider phobia is predominantly mediated through the visual pathway. We report on a congenitally blind person with spider phobia, showing that the acquisition of spider phobia does not necessarily depend on visual cues. PMID:17597227

  7. Mobility and orientation aid for blind persons using artificial vision

    International Nuclear Information System (INIS)

    Blind or vision-impaired persons are limited in their normal life activities. Mobility and orientation of blind persons is an ever-present research subject because no total solution has yet been reached for these activities that pose certain risks for the affected persons. The current work presents the design and development of a device conceived on capturing environment information through stereoscopic vision. The images captured by a couple of video cameras are transferred and processed by configurable and sequential FPGA and DSP devices that issue action signals to a tactile feedback system. Optimal processing algorithms are implemented to perform this feedback in real time. The components selected permit portability; that is, to readily get used to wearing the device

  11. Can blind persons accurately assess body size from the voice?

    Science.gov (United States)

    Pisanski, Katarzyna; Oleszkiewicz, Anna; Sorokowska, Agnieszka

    2016-04-01

    Vocal tract resonances provide reliable information about a speaker's body size that human listeners use for biosocial judgements as well as speech recognition. Although humans can accurately assess men's relative body size from the voice alone, how this ability is acquired remains unknown. In this study, we test the prediction that accurate voice-based size estimation is possible without prior audiovisual experience linking low frequencies to large bodies. Ninety-one healthy congenitally or early blind, late blind and sighted adults (aged 20-65) participated in the study. On the basis of vowel sounds alone, participants assessed the relative body sizes of male pairs of varying heights. Accuracy of voice-based body size assessments significantly exceeded chance and did not differ among participants who were sighted, or congenitally blind or who had lost their sight later in life. Accuracy increased significantly with relative differences in physical height between men, suggesting that both blind and sighted participants used reliable vocal cues to size (i.e. vocal tract resonances). Our findings demonstrate that prior visual experience is not necessary for accurate body size estimation. This capacity, integral to both nonverbal communication and speech perception, may be present at birth or may generalize from broader cross-modal correspondences. PMID:27095264

  13. Some See It, Some Don't: Exploring the Relation between Inattentional Blindness and Personality Factors.

    Directory of Open Access Journals (Sweden)

    Carina Kreitz

    Full Text Available Human awareness is highly limited, which is vividly demonstrated by the phenomenon that unexpected objects go unnoticed when attention is focused elsewhere (inattentional blindness. Typically, some people fail to notice unexpected objects while others detect them instantaneously. Whether this pattern reflects stable individual differences is unclear to date. In particular, hardly anything is known about the influence of personality on the likelihood of inattentional blindness. To fill this empirical gap, we examined the role of multiple personality factors, namely the Big Five, BIS/BAS, absorption, achievement motivation, and schizotypy, in these failures of awareness. In a large-scale sample (N = 554, susceptibility to inattentional blindness was associated with a low level of openness to experience and marginally with a low level of achievement motivation. However, in a multiple regression analysis, only openness emerged as an independent, negative predictor. This suggests that the general tendency to be open to experience extends to the domain of perception. Our results complement earlier work on the possible link between inattentional blindness and personality by demonstrating, for the first time, that failures to consciously perceive unexpected objects reflect individual differences on a fundamental dimension of personality.

  16. Indoor Navigation to Support the Blind Person Using True Pathway within the Map

    Directory of Open Access Journals (Sweden)

    Abbas M. Ali

    2010-01-01

    Full Text Available Problem statement: Map creation remains a very active field in the robotics and AI community, however it contains some challenge points like data association and the high degree of accuracy of localization which are seems to be difficult in some cases, more than that, most of these study focus on the robot navigation, without any consideration for the semantic of the environment, to serve human like blind persons. Approach: This study introduced a monocular SLAM method, which uses the Scale Invariant Features Transform (SIFT representation for the scene. The scene represented as clouds of sift features within the map; this hierarchical representation of space, serving to estimate the current direction in the environment within the current session. The system exploited the tracking of the same features of successive frames to calculate scalar weights for these features, to build a map of the environment indicating the camera movement, then by comparing the camera movement of the current moving with the true pathway within the same session the system can help and advice the blind person to navigate more confidently, through auditory information for the path way in the surroundings. Extended Kalman Filter (EKF used to estimate the camera movement within the successive frames. Results: The experimental work tested using the proposed method with a hand-held camera walking in indoor environment. The results show a good estimation on the spatial locations of the camera within few milliseconds. Tracking of the true pathway in addition to semantic environment within the session can give a good support to the blind person for navigation. Conclusion: The study presented new semantic features model helping the blind person for navigation environment using these clouds of features, for long-term appearance-based localization of a cane with web camera vision as the external sensor.

    2011-06-01

    The aim was to assess glycemia regulation in a blind diabetic patient after getting a guide dog. Glycosylated hemoglobin (HbA1c) results of a blind patient before and after getting the guide dog were retrospectively collected. The paired t-test results yielded a two-tailed P value of 0.0925, a difference considered not statistically significant; the 95% confidence interval of this difference varied from -0.2494 to 1.889. An improvement of glycemia regulation was observed with the guide dog compared to previous glycemia regulation, however, the difference was not statistically significant. The moderate improvement could probably be attributed to the mobility of the blind person having a guide dog. Standard quality of life tests should be included in the evaluation of diabetic blind persons, especially the impact of a guide dog on glycemic control or other chronic complications of diabetes.

    Raheja, Gaurav; Tyagi, Megha

    2016-01-01

    Mobility for persons with visual impairments in Indian railway stations poses multidimensional challenges for access to an inclusive travel experience. India is a home to about twenty million persons with diverse disabilities out of which about five million are persons with visual impairments. Diversity of passenger movements on a railway station including persons with visual impairments requires a Universal Design approach to respond to the accessibility issues in these contexts. This research study is based on a series of live on-site experiences conducted along with persons with visual impairments at New Delhi Railway Station. It also includes the generic studies carried out with other diversities of railway passengers including aging, gender and diverse physical abilities. It employs research methods like ethnography, focus group interactions and trace study to develop a deeper understanding of human and spatial parameters of mobility in railway station environments. A Universal Design perspective with a holistic understanding remains critical to the foundation of this research study. While it deals in specific requirements of persons with visual impairments, it also brings an illustration of handling diversity on a railway station from a unique Indian perspective. It concludes by highlighting and reinterpreting the Universal Design India Principles integrating the needs of persons with visual impairments in railway station environments. Brief recommendation for an inclusive mobility experience on railway station forms a vital part of this grounded research study. PMID:27534355

    Investigations of self-acceptance are critical to understanding the development and maintenance of psychological health. However, valid and reliable instruments for measuring self-acceptance in persons with early blindness have yet to be developed. The current research describes three studies designed to develop and validate the Self-acceptance Scale for Persons with Early Blindness (SAS-EB). In Study 1, we developed the initial item pool. Thirty-three items were generated, based on data from specialized literature and from 2 focus groups. Items were organized in a three-factor structure, theoretically predicted for SAS-EB - (1) body acceptance, (2) self-protection from social stigmas, and (3) feeling and believing in one's capacities. In Study 2, information obtained from a panel of 9 experts and 22 persons with early blindness representing the target population was used to refine the initial item pool, generating a new pool of 27 items. In Study 3, 318 persons with early blindness (141 women and 177 men), between 18 and 60 years of age (M = 37.74 years, SD = 12.37) answered the new pool of 27 items. After the elimination of 9 items using confirmatory factor analysis, we confirmed the theoretical three-factor structure of the SAS-EB. Study 3 also provided support for the scale's internal consistency and construct validity. Finally, the psychometric properties of the SAS-EB, its utility, and its limitations are discussed along with considerations for future research. PMID:25268633

  6. Developing human capital by linking emotional intelligence with personal competencies in Indian business organizations

    Directory of Open Access Journals (Sweden)

    Singh, K.

    2010-01-01

    Full Text Available The concept of emotional intelligence has become so popular in the management literature that it has become imperative to understand and leverage it for the sake of enhancing the capacity of human capital in organizations. As the pace of change is increasing and world of work is making ever greater demands on a person’s cognitive, emotional and physical resources, this particular set of abilities are becoming increasingly important. Since majority of the concerns in organization involve people in different roles, emotional intelligence must become a determining factor for their effective management. It has also been found that ultimately it is the emotional and personal competencies that we need to identify and measure if we want to be able to predict performance at workplace resulting in its effectiveness, thereby enhancing the worth of the human capital. In this scenario the competencies possessed by the people will have a bearing on the extent to which they can actualize their emotional intelligence. The current paper sets out to examine the relationship between the emotional intelligence of executives in Indian business organizations with their personal competencies. The result suggests that emotional intelligence is significantly related with the personal competencies of employees and the variables of personal competency namely, people success, system success and self success have a predictive relationship with emotional intelligence.

    2004-10-01

    Full Text Available Abstract Background We set out to describe the risk of hospitalization from heart disease, stroke, and diabetes among persons born in India, all foreign-born persons, and U.S.-born persons residing in New York City. Methods We examined billing records of 1,083,817 persons hospitalized in New York City during the year 2000. The zip code of each patient's residence was linked to corresponding data from the 2000 U.S. Census to obtain covariates not present in the billing records. Using logistic models, we evaluated the risk of hospitalization for heart disease, stroke and diabetes by country of origin. Results After controlling for covariates, Indian-born persons are at similar risk of hospitalization for heart disease (RR = 1.02, 95% confidence interval 1.02, 1.03, stroke (RR = 1.00, 95% confidence interval, 0.99, 1.01, and diabetes mellitus (RR = 0.96 95% confidence interval 0.94, 0.97 as native-born persons. However, Indian-born persons are more likely to be hospitalized for these diseases than other foreign-born persons. For instance, the risk of hospitalization for heart disease among foreign-born persons is 0.70 (95% confidence interval 0.67, 0.72 and the risk of hospitalization for diabetes is 0.39 (95% confidence interval 0.37, 0.42 relative to native-born persons. Conclusions South Asians have considerably lower rates of hospitalization in New York than reported in countries with national health systems. Access may play a role. Clinicians working in immigrant settings should nonetheless maintain a higher vigilance for these conditions among Indian-born persons than among other foreign-born populations.

    2013-01-01

    大脑可塑性是大脑的主要属性之一,研究大脑可塑性对于揭示大脑活动的规律具有十分重要的意义.很早以前,人们就发现盲人虽然视觉缺失,但是他们的其他功能,如触觉、听觉等都好于正常人,为什么盲人这些方面的功能会好于正常人?研究盲人视皮层重塑对于了解大脑可塑性有着十分重要的作用.20世纪末,学者们开始利用正电子发射断层扫描(PET)、透颅磁刺激(transcranial magnetic stimulation,TMS)、功能磁共振成像(functional magnetic resonance imaging,FMRI)等技术研究盲人视皮层重塑,发现盲人在阅读盲文时,视皮层会被激活,由此得出盲人视皮层重塑的理论依据.但是,目前关于盲人视皮层重塑的机制尚不清楚,如在盲人视皮层重塑的过程中大脑的结构和功能到底发生了哪些变化?诱导大脑结构和功能发生变化的内在机制是什么?本文将结合神经解剖学、神经组织学、神经生理学、认知神经科学等学科的理论探讨盲人视皮层重塑的机制.%Plasticity was one of the most important traits of brain and quite vital for exploring the law of brain activity. Previous studies showed that it was worth considering that blind person with better touching and listening ability than healthy person. Therefore, the plasticity of blind person' s brain was valuabe for study. At the end of 20th centurary, the study results showed that plasticity occurred in blind person' s brain with the technology of positron emission tomography, transcranial magnetic stimulation, functional magnetic resonance imaging. Their visual cortex was activated while reading, however, it was ambiguous. What happened in the brain' s structure during the plasticity process? What was the mechanics? So the changes of neuron-anatomy structure, neuron-histology, neuron-physiology and cognitive neuroscience would be discussed in this article.

    This paper presents a virtual reality system (the BlindAid) developed for orientation and mobility training of people who are newly blind. The BlindAid allows users to interact with different virtual structures and objects via auditory and haptic feedback. This case study aims to examine if and how the BlindAid, in conjunction with a traditional rehabilitation programme, can help people who are newly blind develop new orientation and mobility methods. Follow-up research based on this study, with a large experiment and control group, could contribute to the area of orientation and mobility rehabilitation training for the newly blind. The case study research focused on A., a woman who is newly blind, for 17 virtual sessions spanning ten weeks, during the 12 weeks of her traditional orientation and mobility rehabilitation programme. The research was implemented by using virtual environment (VE) exploration and orientation tasks in VE and physical spaces. The research methodology used both qualitative and quantitative methods, including interviews, questionnaire, videotape recording, and user computer logs. The results of this study helped elucidate several issues concerning the contribution of the BlindAid system to the exploration strategies and learning processes experienced by the participant in her encounters with familiar and unfamiliar physical surroundings.

    The Muslim population of South Africa follows a practice which may be referred to as Muslim personal law. Although section 15 of the Constitution of the Republic of South Africa 108 of 1996 recognises religious freedom and makes provision for the future recognition of other personal law systems, Muslim personal law is, at this stage, not formally recognised in terms of South African law. Since Muslim personal law receives no constitutional recognition the question may be asked whether the 199...

    Full Text Available Context and Objectives: The number of people with diabetes is increasing exponentially in India. Owing to a unique "Asian Indian Phenotype," Indians develop diabetes a decade earlier and have an earlier onset of complications than Western populations. Therefore, it is essential to evaluate more effective treatment strategies at an earlier stage of disease progression, such as initial combination therapy, in Indian patients. In this study, we evaluated the efficacy and safety of initial combination therapy with linagliptin plus metformin in comparison to linagliptin or metformin monotherapy in Indian patients with type 2 diabetes mellitus. Methods: This is a subgroup analysis of Indian patients who participated in a Phase III, 24-week, double-blind, placebo-controlled, trial. Overall, 249 Indian patients were randomized to one of six treatment arms (Two free combination therapy arms: Linagliptin 2.5 mg twice daily [bid] + either low [500 mg, n = 36] or high [1000 mg, n = 44] dose metformin bid and four monotherapy arms: Linagliptin 5 mg once daily [qd, n = 40], metformin 500 mg [n = 49] or 1000 mg bid [n = 45], or placebo [n = 23]. Results: The placebo-corrected mean change in glycated hemoglobin from baseline (8.9% to week 24 was −1.83% for linagliptin + metformin 1000 mg bid; −1.46% for linagliptin + metformin 500 mg bid; −1.30% for metformin 1000 mg bid; −1.00% for metformin 500 mg bid; and −0.77% for linagliptin 5 mg qd. None of the patients in the combination therapy arms had hypoglycemia, whereas there was one event in the metformin 1000 mg bid arm. Rates of adverse event were similar across various treatments. Conclusions: In this subgroup analysis of Indian patients, initial combination therapy with linagliptin + metformin was more efficacious in improving glycemic control than the monotherapy arms, with a comparable tolerability profile. The results were comparable to the overall population.

    Direct reading dosemeter has been used for day-to-day radiation exposure control and management for last four decades in Indian nuclear power plants (NPPs). Recently new real time, alarm and pre-alarm on equivalent dose/dose rate, storage of dose/dose rate and maximum dose rate, user-friendly electronic active personal dosemeter (APD) has been implemented into practice for the first time at Kaiga Atomic Power Station-3&4,  of Indian NPPs. The dosemeter showed tolerance level (L) 0.1085±0.0450 compared with 0.1869±0.0729 (average±SD) for CaSO4:Dy, TL dosemeter, having narrow range trumpet curve, nil electromagnetic interference. Records of >29 000 for APD and TL dosemeter were analysed for comparasion of the measurement of the individual dose. APD followed general acceptance rule of ±25 % for dose >1 mSv. Monthly Station collective dose by TL dosemeters and APD for normal reactor operation as well as outage are found in good agreement. Operational experiences and statistical analysis support that an APD dosemeter is reasonably equivalent to CaSO4:Dy TL dosemeter. The accuracy, reproducibility and repeatability of the measurement of radiation for (137)Cs are comparable with CaSO4:Dy, TL dosemeter. Operational experience of APD during the normal operation as well as outage showed as one of the best ALARA tool for occupational dose monitoring, control, management and future outage planning.

    Full Text Available Background : The B vitamins niacinamide and panthenol have been shown to reduce many signs of skin aging, including hyperpigmentation and redness. Aims : To measure the facial skin effects in Indian women of the daily use of a lotion containing niacinamide, panthenol, and tocopherol acetate using quantitative image analysis. Methods : Adult women 30-60 years of age with epidermal hyperpigmentation were recruited in Mumbai and randomly assigned to apply a test or control lotion to the face daily for 10 weeks. Effects on skin tone were measured using an image capturing system and associated software. Skin texture was assessed by expert graders. Barrier function was evaluated by transepithelial water loss measurements. Subjects and evaluators were blinded to the product assignment. Results : Of 246 women randomized to treatment, 207 (84% completed the study. Women who used the test lotion experienced significantly reduced appearance of hyperpigmentation, improved skin tone evenness, appearance of lightening of skin, and positive effects on skin texture. Improvements versus control were seen as early as 6 weeks. The test lotion was well tolerated. The most common adverse event was a transient, mild burning sensation. Conclusions : Daily use of a facial lotion containing niacinamide, panthenol, and tocopheryl acetate improved skin tone and texture and was well tolerated in Indian women with facial signs of aging.

Second, I address the tactile objects from the point of view of empirical sources and historical evidence. Material objects are rarely used as historical testimonies for the simple reason that they, unlike archival material, do not present historians with written documents that can be held as evidence of the past. However, as I point out, certain historical questions of which archives remain silent could be approached by other means such as the use of material objects. Rather than delivering concrete methodological suggestions, this second part reflects upon the historical use of material objects - both their possibilities and their limits - within the context of blindness.

Methods The study was a double blind, placebo controlled, randomized trial. Sixty subjects with serum LDL values in the range of 130-190 mg/dl and with no history of coronary heart disease were randomized into experimental and placebo groups. The experimental group received 1 gm of the extract for 90 days while the placebo received a similar amount of maltodextrin in addition to dietary and physical activity advice for the control of their blood lipids. Anthropometry, blood biochemistry, dietary and physical activity were assessed at baseline, day 45 and day 90. Results While body weight, serum LDL cholesterol and triglyceride levels decreased in both groups, there were no significant differences between the experimental and placebo group. Conclusions It is likely that the observed effects were as a result of the patients following the standard dietary and physical activity advice. At a dose of 1 gm/day, hibiscus sabdariffa leaf extract did not appear to have a blood lipid lowering effect. Trial Registration REFCTRI2009000472

    Full Text Available Sub-clinical narcissism is the presence of narcissistic personality traits in otherwise normal people. People with high levels of these traits said to have inflated self-esteem and possibly a high egotism. A 40 itemed Narcissistic Personality Inventory is used to measure this type of personality traits. Those individuals who score above 20 points from the available 40 points of NPI-40 Inventory is considered to be having higher levels of Subclinical Narcissism and prone to exhibit socially dislikeable personality traits. This study tried to address the relationship between supposedly negative personality traits of Sub-clinical Narcissism using NPI-40 Score against past and present academic performance of a group of students in a Private University setup. The study included 202 participants from a Business School Division of a Private University. Analysis showed that only at the current academic levels of the respondents, NPI-40 scores were significantly correlating with their academic performance. Research implications are discussed.

The reasons for this excess CHD risk are multifactorial, but in part relate to a susceptibility to diabetes mellitus - where the aberrant metabolism of non-esterified fatty acids (NEFA and glucose are likely to underpin vascular disease in this population. Dietary intervention is an important and first line approach to manage increased CHD risk. However, there is limited information on the impact of the South Asian diet on CHD risk. Methods/Design The Diabetes Health, Residence & Metabolism in Asians (DHRMA study is a blinded, randomised, placebo controlled trial that analyses the efficacy of reduced glycaemic index (GI staples of the South Asian diet, in relation to cardio-metabolic risk factors that are commonly perturbed amongst South Asian populations - primarily glucose, fatty acid and lipoprotein metabolism and central adiposity.

    Full Text Available Introduction. To determine the prevalence and identify potentially curable causes of blindness. Material and methods. We analyzed causes of blindness in 808 blind persons, aged from 0 to 75 years. We classified our findings in 13 categories. Results. The least number of blind persons was discovered in children aged from 0 to 15 years (2.4%, as well as in teenagers (3.4%. The number of blind persons in working population, aged from 30 to 60 was (33.1% and in older population it was (60.7%. Glaucoma was the highest cause of blindness (15.9%. Complications of myopia (14.6% took the second place. Conclusion. We think that our community needs more screening projects for glaucoma, refraction anomalies in children and diabetic retinopathy, through which the causes of blindness would be discovered and treated on time and people would be much more educated about risks and consequences of untreated eye diseases and conditions.

    Cortical blindness following grand mal seizures occurred in five adult patients. The causes of seizures included idiopathic epilepsy, vascular accident, brain cyst, acute encephalitis and chronic encephalitis. Blindness was permanent in one patients, but the others recovered within several days. Since most of the patients were either unaware of or denied their blindness, it is possible that this event often goes unrecognised. Cerebral hypoxia is considered the most likely mechanism.

  18. Indian Summer

    Energy Technology Data Exchange (ETDEWEB)

    Galindo, E. [Sho-Ban High School, Fort Hall, ID (United States)

    1997-08-01

    This paper focuses on preserving and strengthening two resources culturally and socially important to the Shoshone-Bannock Indian Tribe on the Fort Hall Reservation in Idaho; their young people and the Pacific-Northwest Salmon. After learning that salmon were not returning in significant numbers to ancestral fishing waters at headwater spawning sites, tribal youth wanted to know why. As a result, the Indian Summer project was conceived to give Shoshone-Bannock High School students the opportunity to develop hands-on, workable solutions to improve future Indian fishing and help make the river healthy again. The project goals were to increase the number of fry introduced into the streams, teach the Shoshone-Bannock students how to use scientific methodologies, and get students, parents, community members, and Indian and non-Indian mentors excited about learning. The students chose an egg incubation experiment to help increase self-sustaining, natural production of steelhead trout, and formulated and carried out a three step plan to increase the hatch-rate of steelhead trout in Idaho waters. With the help of local companies, governmental agencies, scientists, and mentors students have been able to meet their project goals, and at the same time, have learned how to use scientific methods to solve real life problems, how to return what they have used to the water and land, and how to have fun and enjoy life while learning.

  19. A New Proxy Blind Signature Scheme based on ECDLP

    Directory of Open Access Journals (Sweden)

    Daniyal M Alghazzawi

    2011-05-01

    Full Text Available A proxy blind signature scheme is a special form of blind signature which allows a designated person called proxy signer to sign on behalf of two or more original signers without knowing the content of the message or document. It combines the advantages of proxy signature, blind signature and multi-signature scheme and satisfies the security properties of both proxy and blind signature scheme. Most of the exiting proxy blind signature schemes were developed based on the mathematical hard problems integer factorization (IFP and simple discrete logarithm (DLP which take sub-exponential time to solve. This paper describes an secure simple proxy blind signature scheme based on Elliptic Curve Discrete Logarithm Problem (ECDLP takes fully-exponential time. This can be implemented in low power and small processor mobile devices such as smart card, PDA etc. Here also we describes implementation issues of various scalar multiplication for ECDLP.

    A proxy blind signature scheme is a special form of blind signature which allowed a designated person called proxy signer to sign on behalf of original signers without knowing the content of the message. It combines the advantages of proxy signature and blind signature. Up to date, most proxy blind signature schemes rely on hard number theory problems, discrete logarithm, and bilinear pairings. Unfortunately, the above underlying number theory problems will be solvable in the postquantum era....

    2013-11-01

    Change blindness refers to human inability to recognize large visual changes between images. In this paper, we present the first computational model of change blindness to quantify the degree of blindness between an image pair. It comprises a novel context-dependent saliency model and a measure of change, the former dependent on the site of the change, and the latter describing the amount of change. This saliency model in particular addresses the influence of background complexity, which plays an important role in the phenomenon of change blindness. Using the proposed computational model, we are able to synthesize changed images with desired degrees of blindness. User studies and comparisons to state-of-the-art saliency models demonstrate the effectiveness of our model. PMID:24029902

    Full Text Available Blindness is a state of lacking the visual perception due to physiological or neurological factors. The partial blindness represents the lack of integration in the growth of the optic nerve or visual centre of the eye, and total blindness is the full absence of the visual light perception. In this work, a simple, cheap, friendly user, smart blind guidance system is designed and implemented to improve the mobility of both blind and visually impaired people in a specific area. The proposed work includes a wearable equipment consists of head hat and mini hand stick to help the blind person to navigate alone safely and to avoid any obstacles that may be encountered, whether fixed or mobile, to prevent any possible accident. The main component of this system is the infrared sensor which is used to scan a predetermined area around blind by emitting-reflecting waves. The reflected signals received from the barrier objects are used as inputs to PIC microcontroller. The microcontroller is then used to determine the direction and distance of the objects around the blind. It also controls the peripheral components that alert the user about obstacle's shape, material, and direction. The implemented system is cheap, fast, and easy to use and an innovative affordable solution to blind and visually impaired people in third world countries.

  13. Turning the tide of corneal blindness

    2012-01-01

    Full Text Available Corneal diseases represent the second leading cause of blindness in most developing world countries. Worldwide, major investments in public health infrastructure and primary eye care services have built a strong foundation for preventing future corneal blindness. However, there are an estimated 4.9 million bilaterally corneal blind persons worldwide who could potentially have their sight restored through corneal transplantation. Traditionally, barriers to increased corneal transplantation have been daunting, with limited tissue availability and lack of trained corneal surgeons making widespread keratoplasty services cost prohibitive and logistically unfeasible. The ascendancy of cataract surgical rates and more robust eye care infrastructure of several Asian and African countries now provide a solid base from which to dramatically expand corneal transplantation rates. India emerges as a clear global priority as it has the world′s largest corneal blind population and strong infrastructural readiness to rapidly scale its keratoplasty numbers. Technological modernization of the eye bank infrastructure must follow suit. Two key factors are the development of professional eye bank managers and the establishment of Hospital Cornea Recovery Programs. Recent adaptation of these modern eye banking models in India have led to corresponding high growth rates in the procurement of transplantable tissues, improved utilization rates, operating efficiency realization, and increased financial sustainability. The widespread adaptation of lamellar keratoplasty techniques also holds promise to improve corneal transplant success rates. The global ophthalmic community is now poised to scale up widespread access to corneal transplantation to meet the needs of the millions who are currently blind.

    Approximately 39 million people are blind worldwide, with an estimated 285 million visually impaired. The developing world shoulders 90% of the world's blindness, with 80% of causative diseases being preventable or treatable. Blindness has a major detrimental impact on the patient, community, and healthcare spending. Corneal diseases are significant causes of blindness, affecting at least 4 million people worldwide. The prevalence of corneal disease varies between parts of the world. Trachoma, for instance, is the second leading cause of blindness in Africa, after cataracts, but is rarely found today in developed nations. When preventive strategies have failed, corneal transplantation is the most effective treatment for advanced corneal disease. The major surgical techniques for corneal transplantation include penetrating keratoplasty (PK), anterior lamellar keratoplasty, and endothelial keratoplasty (EK). Indications for corneal transplantation vary between countries, with Fuchs' dystrophy being the leading indication in the USA and keratoconus in Australia. With the exception of the USA, where EK will soon overtake PK as the most common surgical procedure, PK is the overwhelming procedure of choice. Success using corneal grafts in developing nations, such as Nepal, demonstrates the feasibility of corneal transplantation on a global scale. The number of suitable corneas from deceased human donors that becomes available will never be sufficient, and so research into various alternatives, for example stem cells, amniotic membrane transplantation, synthetic and biosynthetic corneas, and xenotransplantation, is progressing. While each of these has potential, we suggest that xenotransplantation holds the greatest potential for a corneal replacement. With the increasing availability of genetically engineered pigs, pig corneas may alleviate the global shortage of corneas in the near future. PMID:25268248

  18. Unconditionally verifiable blind computation

    CERN Document Server

    Fitzsimons, Joseph F

    2012-01-01

    Blind Quantum Computing (BQC) allows a client to have a server carry out a quantum computation for them such that the client's input, output and computation remain private. Recently the authors together with Broadbent proposed a universal unconditionally secure BQC scheme where the client only needs to be able to prepare single qubits in separable states randomly chosen from a finite set and send them to the server, who has the balance of the required quantum computational resources. A desirable property for any BQC protocol is verification, whereby the client can verify with high probability whether the server has followed the instructions of the protocol, or if there has been some deviation resulting in a corrupted output state. A verifiable BQC protocol can be viewed as an interactive proof system leading to consequences for complexity theory. In this paper we extend the BQC protocol presented in [Broadbent, Fitzsimons and Kashefi, FOCS 2009 p517] with new functionality allowing blind computational basis m...

    We investigate the possibility of having someone carry out the work of executing a function for you, but without letting him learn anything about your input. Say Alice wants Bob to compute some well-known function f upon her input x, but wants to prevent Bob from learning anything about x. The situation arises for instance if client Alice has limited computational resources in comparison with mistrusted server Bob, or if x is an inherently mobile piece of data. Could there be a protocol whereby Bob is forced to compute f(x) "blindly", i.e. without observing x? We provide such a blind computation protocol for the class of functions which admit an efficient procedure to generate random input-output pairs, e.g. factorization. The setting is quantum, the security is unconditional, the eavesdropper is as malicious as can be. Keywords: Secure Circuit Evaluation, Secure Two-party Computation, Information Hiding, Information gain vs disturbance.

  1. Stochastic Blind Motion Deblurring

    KAUST Repository

    Xiao, Lei

    2015-05-13

    Blind motion deblurring from a single image is a highly under-constrained problem with many degenerate solutions. A good approximation of the intrinsic image can therefore only be obtained with the help of prior information in the form of (often non-convex) regularization terms for both the intrinsic image and the kernel. While the best choice of image priors is still a topic of ongoing investigation, this research is made more complicated by the fact that historically each new prior requires the development of a custom optimization method. In this paper, we develop a stochastic optimization method for blind deconvolution. Since this stochastic solver does not require the explicit computation of the gradient of the objective function and uses only efficient local evaluation of the objective, new priors can be implemented and tested very quickly. We demonstrate that this framework, in combination with different image priors produces results with PSNR values that match or exceed the results obtained by much more complex state-of-the-art blind motion deblurring algorithms.

Refraction and low vision workup was done where indicated. World Health Organization′s reporting form was used to code anatomical and etiological causes of visual loss. Statistical Analysis: Microsoft Excel Windows software with SPSS. Results: A total of 376 students were examined of whom 258 fulfilled the eligibility criteria. The major anatomical causes of visual loss amongst the 258 were congenital anomalies (anophthalmos, microphthalmos 93 (36.1%; corneal conditions (scarring, vitamin A deficiency 94 (36.7%; cataract or aphakia 28 (10.9%, retinal disorders 15 (5.8% and optic atrophy 14 (5.3%. Nearly half of the children were blind from conditions which were either preventable or treatable (48.5%. Conclusion: Nearly half the childhood blindness in the NER states of India is avoidable and Vitamin A deficiency forms an important component unlike other Indian states. More research and multisectorial effort is needed to tackle congenital anomalies.

    This work is developed within the scope of rehabilitation technology to enable blind and visually impaired persons read non-Braille material commonly available in digital form to normal-vision readers. This approach, therefore, tries to broaden the reaching capacity for these persons and, thus, allow for better inclusion in social, work, educative and even leisure activities. Specifically, it is devised for reading any kind of text in digital form --books, files, documents, Internet information and exchanges, etc.-- that can be loaded in a PC to be later read on the devised Braille reading line. It consists of a string-like platform of electrodes that simulate, through tactile electrostimulation, the letter characters displayed in Braille fashion. Finger-tip feeling from these electric discharges is caused by stimulating the skin nerve receptors underneath the tip. These electric discharges produce a similar effect as when reading embossed-type characters of traditional Braille-relief paper material. After design and development, experiences were made with blind persons, with fairly satisfactory results. At present, further work is under way in order to improve the system.

    Full Text Available Purpose: To characterize the demographic and psychosocial problems of a group of blind people as a way of attracting more attention to and providing data that can improve the psychosocial care of the visually impaired. Materials and Method: A cross-sectional descriptive study of a population of totally blind people in Ilorin, Nigeria using a self-report questionnaire (SRQ. The questionnaire was verbally administered by the study personnel in the local language. Simple frequency tables were obtained and the Chi-square test was performed to determine significant differences between variables. P-value <0.05 was considered statistically significant. Results: Sixty one blind patients consented to participate. Most participants were engaged in street begging for their livelihood. Most subjects desired a job change, signifying dissatisfaction with the present occupation. Up to 80% of the cohort was married and had spouses who were also blind in at least one eye. Approximately two-thirds had five or more children and majority lived with family members who were responsible for taking care of their personal hygiene, cooking and mobility. The majority developed blindness in childhood and 16% had a family history of blindness and 77% had never used conventional eye care, with corneal disease being the most frequent cause of blindness. Many feared that their children may also become blind. Thirty-one (51% scored ≥5 on SRQ and were classified as probable cases of psychological disorder. Conclusion: Blindness in a majority of cases that started in childhood was probably preventable. Inaccessibility to or failure of the formal rehabilitation and social welfare systems may have caused this psychosocial dilemma. The high level of social and family interaction provides opportunity for organized preventive ophthalmology, community health care services and psychosocial care.

    Full Text Available BACKGROUND: The majority of vision loss is preventable or treatable. Population surveys are crucial for planning, implementation, and monitoring policies and interventions to eliminate avoidable blindness and visual impairments. This is the first rapid assessment of avoidable blindness (RAAB study in Thailand. METHODS: A cross-sectional study of a population in Thailand age 50 years old or over aimed to assess the prevalence and causes of blindness and visual impairments. Using the Thailand National Census 2010 as the sampling frame, a stratified four-stage cluster sampling based on a probability proportional to size was conducted in 176 enumeration areas from 11 provinces. Participants received comprehensive eye examination by ophthalmologists. RESULTS: The age and sex adjusted prevalence of blindness (presenting visual acuity (VA <20/400, severe visual impairment (VA <20/200 but ≥20/400, and moderate visual impairment (VA <20/70 but ≥20/200 were 0.6% (95% CI: 0.5-0.8, 1.3% (95% CI: 1.0-1.6, 12.6% (95% CI: 10.8-14.5. There was no significant difference among the four regions of Thailand. Cataract was the main cause of vision loss accounted for 69.7% of blindness. Cataract surgical coverage in persons was 95.1% for cut off VA of 20/400. Refractive errors, diabetic retinopathy, glaucoma, and corneal opacities were responsible for 6.0%, 5.1%, 4.0%, and 2.0% of blindness respectively. CONCLUSION: Thailand is on track to achieve the goal of VISION 2020. However, there is still much room for improvement. Policy refinements and innovative interventions are recommended to alleviate blindness and visual impairments especially regarding the backlog of blinding cataract, management of non-communicative, chronic, age-related eye diseases such as glaucoma, age-related macular degeneration, and diabetic retinopathy, prevention of childhood blindness, and establishment of a robust eye health information system.

    2015-09-01

    Full Text Available BACKGROUND: It is estimated that there are 1.4 million irreversibly blind children in the world out of which 1 million are in Asia alone. India has the highest number of blind children than any other country. Nearly 70% of the childhood blindness is avoidable. There i s paucity of data available on the causes of childhood blindness. This study focuses on the posterior segment causes of blindness among children attending blind schools in 3 adjacent districts of Andhra Pradesh. MATERIAL & METHODS: This is a cross sectiona l study conducted among 204 blind children aged 6 - 16 years age. Detailed eye examination was done by the same investigator to avoid bias. Posterior segment examination was done using a direct and/or indirect ophthalmoscope after dilating pupil wherever nec essary. The standard WHO/PBL for blindness and low vision examination protocol was used to categorize the causes of blindness. A major anatomical site and underlying cause was selected for each child. The study was carried out during July 2014 to June 2015 . The results were analyzed using MS excel software and Epi - info 7 software version statistical software. RESULTS: Majority of the children was found to be aged 13 - 16 years (45.1% and males (63.7%. Family history of blindness was noted in 26.0% and consa nguinity was reported in 29.9% cases. A majority of them were belonged to fulfill WHO grade of blindness (73.0% and in majority of the cases, the onset of blindness was since birth (83.7%. The etiology of blindness was unknown in majority of cases (57.4% while hereditary causes constituted 25.4% cases. Posterior segment causes were responsible in 33.3% cases with retina being the most commonly involved anatomical site (19.1% followed by optic nerve (14.2%. CONCLUSIONS: There is a need for mandatory oph thalmic evaluation, refraction and assessment of low vision prior to admission into blind schools with periodic evaluation every 2 - 3 years

  20. Blind Known Interference Cancellation

    CERN Document Server

    Zhang, Shengli; Wang, Hui

    2011-01-01

    This paper investigates interference-cancellation schemes at the receiver, in which the original data of the interference is known a priori. Such a priori knowledge is common in wireless relay networks. For example, a transmitting relay could be relaying data that was previously transmitted by a node, in which case the interference received by the node now is actually self information. Besides the case of self information, the node could also have overheard or received the interference data in a prior transmission by another node. Directly removing the known interference requires accurate estimate of the interference channel, which may be difficult in many situations. In this paper, we propose a novel scheme, Blind Known Interference Cancellation (BKIC), to cancel known interference without interference channel information. BKIC consists of two steps. The first step combines adjacent symbols to cancel the interference, exploiting the fact that the channel coefficients are almost the same between successive sy...

  1. The superiority in voice processing of the blind arises from neural plasticity at sensory processing stages.

    Föcker, Julia; Best, Anna; Hölig, Cordula; Röder, Brigitte

    2012-07-01

    Blind people rely much more on voices compared to sighted individuals when identifying other people. Previous research has suggested a faster processing of auditory input in blind individuals than sighted controls and an enhanced activation of temporal cortical regions during voice processing. The present study used event-related potentials (ERPs) to single out the sub-processes of auditory person identification that change and allow for superior voice processing after congenital blindness. A priming paradigm was employed in which two successive voices (S1 and S2) of either the same (50% of the trials) or different actors were presented. Congenitally blind and matched sighted participants made an old-young decision on the S2. During the pre-experimental familiarization with the stimuli, congenitally blind individuals showed faster learning rates than sighted controls. Reaction times were shorter in person-congruent trials than in person-incongruent trials in both groups. ERPs to S2 stimuli in person-incongruent as compared to person-congruent trials were significantly enhanced at early processing stages (100-160 ms) in congenitally blind participants only. A later negative ERP effect (>200 ms) was found in both groups. The scalp topographies of the experimental effects were characterized by a central and parietal distribution in the sighted but a more posterior distribution in the congenitally blind. These results provide evidence for an improvement of early voice processing stages and a reorganization of the person identification system as a neural correlate of compensatory behavioral improvements following congenital blindness.

    Full Text Available Introduction. Visual impairment and blindness are serious social and health problems in the world. 1992 classification of visual disorders by World Health Organization has recently been implemented. The goal of this study was to determine common causes of visual impairment and blindness in the region of Eastern Herzegovina. Material and methods. In this population based study we have analyzed medical records stored in the regional Association of Visually Impaired and Blind Persons of the Republic of Srpska (Trebinje, Bileća, Foča, Eastern Sarajevo. The analysis included sex and age distribution of registered population, classification and leading causes of visual disability and blindness. Results. There are 298 registered persons with visual disability and blindness in the region of Eastern Herzegovina and Eastern Sarajevo. The prevalence of visual impairment and blindness in the aforementioned region is 0.1%. Among the studied population, there are more males than females with visual disability or blindness (56% versus 44%. Most (78% of registered persons are blind, and only 22% are visually impaired. 43% of registered population are in the IV category and only 8.38% are registered in the II category. Only 2% of registered population are children. Common causes of visual disability and blindness in the region of Eastern Herzegovina are: glaucoma (22%, cataract (17%, myopia alta (13%, diabetic retinopathy (12% and ocular trauma (11%. Common causes of children's visual impairment include: optic nerve anomalies, congenital cataract and premature retinopathy. Discussion and conclusion Compared with literature data, common causes of blindness and visual impairment in the region of Eastern Herzegovina do not differ significantly from those in other regions. Registration is based on the WHO model, but it is possible only by performing active epidemiological studies. .

The society has an active chapter at Kolkata. The society was formed with the main aim to promote, encourage and develop the growth of Vacuum Science, Techniques and Applications in India. In order to achieve this aim it has conducted a number of short term courses at graduate and technician levels on vacuum science and technology on topics ranging from low vacuum to ultrahigh vacuum So far it has conducted 39 such courses at different parts of the country and imparted training to more than 1200 persons in the field. Some of these courses were in-plant training courses conducted on the premises of the establishment and designed to take care of the special needs of the establishment. IVS also regularly conducts national and international seminars and symposia on vacuum science and technology with special emphasis on some theme related to applications of vacuum. A large number of delegates from all over India take part in the deliberations of such seminars and symposia and present their work. IVS also arranges technical visits to different industries and research institutes. The society also helped in the UNESCO sponsored post-graduate level courses in vacuum science, technology and applications conducted by Mumbai University. The society has also designed a certificate and diploma course for graduate level students studying vacuum science and technology and has submitted a syllabus to the academic council of the University of Mumbai for their approval, we hope that some colleges affiliated to the university will start this course from the coming academic year. IVS extended its support in standardizing many of the vacuum instruments and played a vital role in helping to set up a Regional Testing Centre along with BARC.

  14. The global cost of eliminating avoidable blindness

    Directory of Open Access Journals (Sweden)

    Kirsten L Armstrong

    2012-01-01

    Full Text Available Aims : To complete an initial estimate of the global cost of eliminating avoidable blindness, including the investment required to build ongoing primary and secondary health care systems, as well as to eliminate the ′backlog′ of avoidable blindness. This analysis also seeks to understand and articulate where key data limitations lie. Materials and Methods : Data were collected in line with a global estimation approach, including separate costing frameworks for the primary and secondary care sectors, and the treatment of backlog. Results : The global direct health cost to eliminate avoidable blindness over a 10-year period from 2011 to 2020 is estimated at $632 billion per year (2009 US$. As countries already spend $592 billion per annum on eye health, this represents additional investment of $397.8 billion over 10 years, which is $40 billion per year or $5.80 per person for each year between 2010 and 2020. This is concentrated in high-income nations, which require 68% of the investment but comprise 16% of the world′s inhabitants. For all other regions, the additional investment required is $127 billion. Conclusions : This costing estimate has identified that low- and middle-income countries require less than half the additional investment compared with high-income nations. Low- and middle-income countries comprise the greater investment proportion in secondary care whereas high-income countries require the majority of investment into the primary sector. However, there is a need to improve sector data. Investment in better data will have positive flow-on effects for the eye health sector.

    We present a real-time vision system to assist blind and visually impaired persons. This system complements the white cane, and it can be used both indoor and outdoor. It detects borders of paths and corridors, obstacles within the borders, and it provides guidance for centering and obstacle avoidance. Typical obstacles are backpacks, trash cans, trees, light poles, holes, branches, stones and other objects at a distance of 2 to 5 meters from the camera position. Walkable paths ar...

  2. PARLOMA – A Novel Human-Robot Interaction System for Deaf-Blind Remote Communication

    2015-05-01

    Full Text Available Deaf-blindness forces people to live in isolation. At present, there is no existing technological solution enabling two (or many deaf-blind people to communicate remotely among themselves in tactile Sign Language (t-SL. When resorting to t-SL, deaf-blind people can communicate only with people physically present in the same place, because they are required to reciprocally explore their hands to exchange messages. We present a preliminary version of PARLOMA, a novel system to enable remote communication between deaf-blind persons. It is composed of a low-cost depth sensor as the only input device, paired with a robotic hand as the output device. Essentially, any user can perform hand-shapes in front of the depth sensor. The system is able to recognize a set of hand-shapes that are sent over the web and reproduced by an anthropomorphic robotic hand. PARLOMA can work as a "telephone" for deaf-blind people. Hence, it will dramatically improve the quality of life of deaf-blind persons. PARLOMA has been presented and supported by the main Italian deaf blind association, Lega del Filo d'Oro. End users are involved in the design phase.

    outputs are indistinguishable for a given environment in the same way as a color-blind person cannot distinguish some colors. Color-blindness can be used to model surprisingly many aspects of realistic environments (for example causality between firing and timing-out of a stop-watch, boolean memory flags......, or use of a single actuator in place of two). The environments which are formalized as color-blind I/O-alternating transition systems, can also describe dynamic properties such as; an output that is ignored only after a certain set of other outputs....

    2015-01-01

    Full Text Available BACKGROUND AND OBJECTIVE : Tibetans are the oldest population living permanently at high altitude (4000m. This ethnic group along with Sherpas may have been living at high altitude for longer than any other population. Previous research has shown Tibetans living at high altitude to have superior pulmonary functions. The size of the lungs relative to the size of the person varies depending on eth nic group and a host of environmental factors. Peak expiratory flow rate (PEFR measurement is the easiest and cheapest method to evaluate respiratory functions. MVV tests the overall functioning of the respiratory system, the respiratory muscles, airway r esistance and compliance of lungs and chest wall. So, the study was carried out to evaluate PEFR and MVV of healthy Tibetans youths born and brought up in India and compare their values with healthy Indian youths , to know whether Tibetans born and brought up in India (sea level retain better respiratory parameters as their ancestors (born at high altitude. MATERIALS AND METHOD : A comparative study was conducted in which the PEFR and MVV of 50 Tibetan male youths born and brought up in Mundgod , North Karnataka district , Hubli , in the age group of 20 - 30yrs were compared with 50 Indian male youths matched for age and sex as controls. The PEFR and MVV were measured with spiroanalyser SPL - 95. The obtained data was analysed using unpaired student’s ‘t ’ test. RESULTS : The Indian born Tibetan male youths had a PEFR (L/sec of value 8.18 2.47 where as the corresponding value for Indian male youths was 4.86 1.89. The PEFR was higher in Indian born Tibetan male youths than Indian male youths. This was stat istically highly significant at (P<0.001. The Tibetan youths had a MVV (L/min of value 116.16 25.78 whereas the corresponding value for Indian youths was 101.49 19.21.The MVV was less in Indian youths than Tibetan youths. This was statistically signi ficant at p<0.01. CONCLUSION : Though both

    Aim: To evaluate the prevalence and causes of low vision and blindness in an urban south Indian population. Settings and Design: Population-based cross-sectional study. Exactly 3850 subjects aged 40 years and above from Chennai city were examined at a dedicated facility in the base hospital. Materials and Methods: All subjects had a complete ophthalmic examination that included best-corrected visual acuity. Low vision and blindness were defined using World Health Organization (WHO) criteria. The influence of age, gender, literacy, and occupation was assessed using multiple logistic regression. Statistical Analysis: Chi-square test, t-test, and multivariate analysis were used. Results: Of the 4800 enumerated subjects, 3850 subjects (1710 males, 2140 females) were examined (response rate, 80.2%). The prevalence of blindness was 0.85% (95% CI 0.6–1.1%) and was positively associated with age and illiteracy. Cataract was the leading cause (57.6%) and glaucoma was the second cause (16.7%) for blindness. The prevalence of low vision was 2.9% (95% CI 2.4–3.4%) and visual impairment (blindness + low vision) was 3.8% (95% CI 3.2–4.4%). The primary causes for low vision were refractive errors (68%) and cataract (22%). Conclusions: In this urban population based study, cataract was the leading cause for blindness and refractive error was the main reason for low vision. PMID:23619490

    India is a vast country depicting wide social, cultural and sexual variations. Indian concept of sexuality has evolved over time and has been immensely influenced by various rulers and religions. Indian sexuality is manifested in our attire, behavior, recreation, literature, sculptures, scriptures, religion and sports. It has influenced the way we perceive our health, disease and device remedies for the same. In modern era, with rapid globalization the unique Indian sexuality is getting diffused. The time has come to rediscover ourselves in terms of sexuality to attain individual freedom and to reinvest our energy to social issues related to sexuality. PMID:23858263

    2015-03-01

    Glaucoma is the leading cause of acquired blindness in Japan. One reason that it often leads to blindness is that it can continue to worsen even after effective medical reduction of intraocular pressure (IOP), the only evidence-based treatment. The limitations of current treatments make it critical to identify IOP-independent factors that can cause glaucoma and develop new drugs to target these factors. This is a challenging task, as the pathology of glaucoma is thought to be very complex, with different combinations of factors underlying its development and progression in different patients. Additionally, there is a deficiency in methods to efficiently perform clinical evaluations and reliably probe the state of the disease over relatively short periods. In addition, newly developed drugs need to be evaluated with clinical trials, for which human and financial resources are limited, before they can be widely used for treatment. Taking all these issues into consideration, it is evident that there are two urgent issues to consider: the development of methods to classify glaucoma in detail based on its pathology, and the improvement of clinical evaluation methods. In this review, we discuss some of our efforts to develop new neuroprotective agents for glaucoma, with a focus on the following three areas: 1. Clinical research and development of methods to classify glaucoma in detail based on IOP-independent factors, and the exploration of possibilities for the improvement of clinical evaluation of glaucoma. 2. Pathology-based research and development of new drugs for glaucoma, focusing on comprehensive gene expression analysis and the development of molecule-targeting drugs, using murine optic nerve crush as a disease model. 3. Development of next generation in vivo imaging modalities and the establishment of infrastructure enabling "big-data" analysis. First, we discuss our clinical research and the development of methods to classify glaucoma in detail based on IOP

    Full Text Available Introduction Cataract is the second leading cause of blindness and visual disability in the region of Eastern Herzegovina and Eastern Sarajevo. It is a curable and preventable cause of blindness, because visual function can be surgically recovered. The aim of our study was to determine the frequency of cataract among registered blind population. .Material and methods We used data stored in the Regional Association of Blind Persons from municipalities of Eastern Herzegovina (Trebinje, Kileča, Foča and Eastern Sarajevo. In this population-based study data were analyzed using standard statistical methods. We have investigated sex and age distribution, visual acuity and type of cataract in the registered population. Results Among 298 registered blind persons and persons with visual disability, 17% are persons with cataract Males are more frequent than women. Most people with cataract are older than on and are with age-related cataract. Discussion and conclusion Literature data show that cataract is one of the leading causes of blindness and visual disability in the world. Cataract is the second leading cause of visual disability and blindness in the registered population of Eastern Herzegovina. The total number of people with visual disability caused by cataract would decrease by increasing the number of surgeries, which correlates with improving the quality and training of ophthalmologists.

  17. PROXY BLIND SIGNATURE BASED ON ECDLP

    Directory of Open Access Journals (Sweden)

    SATARUPA PRADHAN,

    2011-03-01

    Full Text Available Proxy blind signature combines the properties of both proxy signature and blind signature. In a proxy signature scheme, a signer delegates his signing power to a proxy, who signs a message on behalf of the original signer. In a blind signature scheme, the signer cannot link the relationship between the blind message and the signature of the chosen message. Therefore, it is very suitable for electronic commerceapplication. In this paper, a proxy blind signature scheme based on ECDLP (Elliptic Curve Discrete Logarithm Problem has been proposed, which satisfy the security properties of both the blind signature and the proxy signature. Analysis shows that our scheme is secure and efficient.

  19. [The punishment of blinding and the life of the blind].

    Büttner, Jan Ulrich

    2009-01-01

    The article deals with a group of people who were deprived of their eyesight by private acts of force or by executions of lawful sentences. In early medieval texts blinding is frequently mentioned in connection with popes, kings, princes or bishops. However, since the High Middle Ages these dignitaries were increasingly spared the loss of their eyes. It may be said that on the whole, from the eighth to the twelfth century, blinding was overwhelmingly used to dispose of political adversaries, but did then rapidly turn into a criminal punishment. In the earliest 'Landfriedensordnungen' of the late eleventh century, the loss of the perpetrator's eyes crops up as punishment for breach of the peace, while later it was applied to a variety of more or less serious offences. The destiny of the blinded in the early Middle Ages is only highlighted by sketches of a few individual cases; for the High and late Middle Ages--apart from a few notable exceptions--it is only possible to reflect on the general situation of blind people in society, since the sources usually do not differentiate between those having lost their sight through human violence or due to other causes.

    Full Text Available This project is developed to make the life of blind people easy. This is a camera based system to scan the barcode behind the image and read the description of the product with the help of Id stored in the barcode. This is very beneficial in case of finding out the description of packaged goods to the blind people and thus helping them in deciding to purchase a product or not especially which are packaged. This is because it becomes very difficult for the blind people to distinguish between the packaged goods. In order to use this system, all the user needs to do is capture the image on the product in the mobile phone which then resolves the barcode which means it scans the image to find out the Id stored. Thus this application really benefits blind and visually impaired people and thus making their work of identifying products easy. This is very easy to use and affordable as it requires a scanner to scan the barcode and a camera phone to take the picture of the image containing the barcode. This is now easy to implement as most of the mobile phones today have the required resolution in order to scan the barcode to identify the Id stored in it and read out the product description. This project can be implemented in any shopping mall, supermarket, Book stores, Medical stores etc.

    2010-07-01

    Full Text Available Background: Immunity status, individual response to disease and types of antibodies produced are well known to vary from person to person, place to place and probably from population to population. A broad spectrum of specific auto antibodies that have so far been associated with specific rheumatic diseases, as noted in Western literature, has been well taken as a reference standard all over the world. There is neither research work nor any data correlating the auto antibodies and their antinuclear antibody (ANA patterns with the immunoprofile in the Indian population to date. Aims: To understand a definite association between ANA patterns and specific antibodies in the serum in the Indian study population and to document similarities / differences with the West. Settings and Design: This prospective and retrospective double blind study was undertaken on the South Indian population referred for ANA testing by Indirect Immunofluorescence method and by immunoline methods. Materials and Methods: Serum samples of patients from a random South Indian population who sought medical help for rheumatic disease were subjected for ANA testing by indirect immunofluorescence (IIF method and line immunoassay during the study period of 27 months. Serum samples were processed in dilution of 1:100 using HEp - 2010 / liver biochip (Monkey (EUROIMMUN AG. The serum samples which were further processed for line immunoassay were treated in 1:100 dilution on nylon strips coated with recombinant and purified antigens as discrete lines with plastic backing (EUROIMMUN AG coated with antigens nRNP / Sm, Sm, SSA, Ro-52, SSB, Scl-70, PM-Scl, PCNA, Jo-1, CENP-B, dsDNA, nucleosomes, histones, ribosomal protein-P, anti-mitochondrial antibodies (AMA-M2 along with a control band.

  4. A Lattice-Based Identity-Based Proxy Blind Signature Scheme in the Standard Model

    Directory of Open Access Journals (Sweden)

    Lili Zhang

    2014-01-01

    Full Text Available A proxy blind signature scheme is a special form of blind signature which allowed a designated person called proxy signer to sign on behalf of original signers without knowing the content of the message. It combines the advantages of proxy signature and blind signature. Up to date, most proxy blind signature schemes rely on hard number theory problems, discrete logarithm, and bilinear pairings. Unfortunately, the above underlying number theory problems will be solvable in the postquantum era. Lattice-based cryptography is enjoying great interest these days, due to implementation simplicity and provable security reductions. Moreover, lattice-based cryptography is believed to be hard even for quantum computers. In this paper, we present a new identity-based proxy blind signature scheme from lattices without random oracles. The new scheme is proven to be strongly unforgeable under the standard hardness assumption of the short integer solution problem (SIS and the inhomogeneous small integer solution problem (ISIS. Furthermore, the secret key size and the signature length of our scheme are invariant and much shorter than those of the previous lattice-based proxy blind signature schemes. To the best of our knowledge, our construction is the first short lattice-based identity-based proxy blind signature scheme in the standard model.

  5. Blind prediction exercise on modeling of PHWR fuel at extended burnup

    International Nuclear Information System (INIS)

    A blind prediction exercise was organised on Indian Pressurised Heavy Water Reactor (PHWR) fuel to investigate the predictive capability of existing codes for their application at extended burnup and to identify areas of improvement. The blind problem for this exercise was based on a PHWR fuel bundle irradiated in Kakrapar Atomic Power Station-I (KAPS-I) up to about 15 000 MWd/tU and subjected to detailed post-irradiation examination (PIE) in the hot cells facility at BARC. Eleven computer codes from seven countries participated in this exercise. The participants provided blind predictions of fuel temperature, fission gas release, internal gas pressure and other performance parameters for the fuel pins. The predictions were compared with the experimental PIE data which included fuel temperature derived from fuel restructuring, fission gas release measured by fuel pin puncturing, internal gas pressure in pin, cladding oxidation and fuel microstructural data. The details of the blind problem and an analysis of the results of blind predictions by the codes vis-a-vis measured data are provided in this paper

  7. Indian Ocean Traffic: Introduction

    Directory of Open Access Journals (Sweden)

    Lola Sharon Davidson

    2012-06-01

    Full Text Available Like the Mediterranean, the Indian Ocean has been a privileged site of cross-cultural contact since ancient times. In this special issue, our contributors track disparate movements of people and ideas around the Indian Ocean region and explore the cultural implications of these contacts and their role in processes that we would come to call transnationalization and globalisation. The nation is a relatively recent phenomenon anywhere on the globe, and in many countries around the Indian Ocean it was a product of colonisation and independence. So the processes of exchange, migration and cultural influence going on there for many centuries were mostly based on the economics of goods and trade routes, rather than on national identity and state policy.

    The blind and visually impaired people are facing a number of challenges in their daily life. One of the major challenges is finding their way both indoor and outdoor. For this reason, routing and navigation independently, especially in urban areas are important for the blind. Most of the blind undertake route finding and navigation with the help of a guide. In addition, other tools such as a cane, guide dog or electronic aids are used by the blind. However, in some cases these aids are not efficient enough in a wayfinding around obstacles and dangerous areas for the blind. As a result, the need to develop effective methods as decision support using a non-visual media is leading to improve quality of life for the blind through their increased mobility and independence. In this study, we designed and implemented an outdoor mobile sensor-based wayfinding system for the blind. The objectives of this study are to guide the blind for the obstacle recognition and the design and implementation of a wayfinding and navigation mobile sensor system for them. In this study an ultrasonic sensor is used to detect obstacles and GPS is employed for positioning and navigation in the wayfinding. This type of ultrasonic sensor measures the interval between sending waves and receiving the echo signals with respect to the speed of sound in the environment to estimate the distance to the obstacles. In this study the coordinates and characteristics of all the obstacles in the study area are already stored in a GIS database. All of these obstacles were labeled on the map. The ultrasonic sensor designed and constructed in this study has the ability to detect the obstacles in a distance of 2cm to 400cm. The implementation and the results obtained from the interview of a number of blind persons who employed the sensor verified that the designed mobile sensor system for wayfinding was very satisfactory.

    2006-01-01

    Threshold digital signature and blind signature are playing important roles in cryptography as well as in practical applications such as e-cash and e-voting systems.Over the past few years, many cryptographic researchers have made considerable headway in this field. However, to our knowledge, most of existing threshold blind signature schemes are based on the discrete logarithm problem. In this paper, we propose a new robust threshold partial blind signature scheme based on improved RSA cryptosystem.This scheme is the first threshold partial blind signature scheme based on factoring, and the robustness of threshold partial blind signature is also introduced. Moreover, in practical application, the proposed scheme will be especially suitable for blind signature-based voting systems with multiple administrators and secure electronic cash systems to prevent their abuse.

    2015-08-01

    Recently, some quantum blind signature protocols have been proposed. However, the previous schemes cannot satisfy the unlinkability requirement. To overcome the drawback of unlinkability in the previous schemes, we propose a new quantum blind signature based on Bell states with the help of an authentic party. In this paper, we provide a method to inject a randomizing factor into a message when it is signed by the signer and then get rid of the blind factor from the blinded signature when it is verified by the verifier. Even when the message owner publishes the message-signature pair, the signer cannot identify the association between the message-signature pair and the blind signature he generated. Therefore, our scheme really realizes unlinkability property. At last, analysis results show that this scheme satisfies the basis security requirements of a weak signature such as no-counterfeiting, no-disavowing, blindness and traceability, and our total efficiency is not less than the previous schemes.

    In profound impairement of vision the function of colour and seen objects perception is absent, with the person being unable to orient himself in space. The uncovered sensory sensations of colour allowed their use in training the blind in recognizing the colour of paper, fabric, etc. Further study in those having become blind will, we believe, help in finding eligible people and relevant approaches toward educating the blind, which will make for development of the trainee's ability to recognize images on the "inner visual screen".

  1. Sensory augmentation for the blind

    2012-03-01

    Full Text Available Enacted theories of consciousness conjecture that perception and cognition arise from an active experience of the regular relations that are tying together the sensory stimulation of different modalities and associated motor actions. Previous experiments investigated this concept by employing the technique of sensory substitution. Building on these studies, here we test a set of hypotheses derived from this framework and investigate the utility of sensory augmentation in handicapped people. We provide a late blind subject with a new set of sensorimotor laws: A vibro-tactile belt continually signals the direction of magnetic north. The subject completed a set of behavioral tests before and after an extended training period. The tests were complemented by questionnaires and interviews. This newly supplied information improved performance on different time scales. In a pointing task we demonstrate an instant improvement of performance based on the signal provided by the device. Furthermore, the signal was helpful in relevant daily tasks, often complicated for the blind, such as keeping a direction over longer distances or taking shortcuts in familiar environments. A homing task with an additional attentional load demonstrated a significant improvement after training. The subject found the directional information highly expedient for the adjustment of his inner maps of familiar environments and describes an increase in his feeling of security when exploring unfamiliar environments with the belt. The results give evidence for a firm integration of the newly supplied signals into the behavior of this late blind subject with better navigational performance and more courageous behavior in unfamiliar environments. Most importantly, the complementary information provided by the belt lead to a positive emotional impact with enhanced feeling of security. This experimental approach demonstrates the potential of sensory augmentation devices for the help of

    2008-01-01

    Certificateless public key cryptography is a new paradigm introduced by AI-Riyami and Paterson. It eliminates the need of the certificates in traditional public key cryptosystems and the key escrow problem in IDentity-based Public Key Cryptography (ID-PKC). Due to the advantages of the certificateless public key cryptography,a new efficient certificateless pairing-based signature scheme is presented,which has some advantages over previous constructions in computational cost. Based on this new signature scheme,a certificateless blind signature scheme is proposed. The security of our schemes is proven based on the hardness of computational Diffie-Hellman problem.

    This conceptual, perspective and review paper on Indian scales and inventories begins with clarification on the historical and contemporary meanings of psychometry before linking itself to the burgeoning field of clinimetrics in their applications to the practice of clinical psychology and psychiatry. Clinimetrics is explained as a changing paradigm in the design, administration, and interpretation of quantitative tests, techniques or procedures applied to measurement of clinical variables, traits and processes. As an illustrative sample, this article assembles a bibliographic survey of about 105 out of 2582 research papers (4.07%) scanned through 51 back dated volumes covering 185 issues related to clinimetry as reviewed across a span of over fifty years (1958-2009) in the Indian Journal of Psychiatry. A content analysis of the contributions across distinct categories of mental measurements is explained before linkages are proposed for future directions along these lines. PMID:21836709

    Full Text Available Personality is the integration of characteristics acquired or brought by birth which separate the individual from others. Personality involves aspects of the individual's mental, emotional, social, and physical features in continuum. Several theories were suggested to explain developmental processes of personality. Each theory concentrates on one feature of human development as the focal point, then integrates with other areas of development in general. Most theories assume that childhood, especially up to 5-6 years, has essential influence on development of personality. The interaction between genetic and environmental factors reveals a unique personality along growth and developmental process. It could be said that individual who does not have any conflict between his/her basic needs and society's, has well-developed and psychologically healthy personality.

  18. A comparative study of simple auditory reaction time in blind (congenitally and sighted subjects

    2013-01-01

    Full Text Available Background: Reaction time is the time interval between the application of a stimulus and the appearance of appropriate voluntary response by a subject. It involves stimulus processing, decision making, and response programming. Reaction time study has been popular due to their implication in sports physiology. Reaction time has been widely studied as its practical implications may be of great consequence e.g., a slower than normal reaction time while driving can have grave results. Objective: To study simple auditory reaction time in congenitally blind subjects and in age sex matched sighted subjects. To compare the simple auditory reaction time between congenitally blind subjects and healthy control subjects. Materials and Methods: Study had been carried out in two groups: The 1 st of 50 congenitally blind subjects and 2 nd group comprises of 50 healthy controls. It was carried out on Multiple Choice Reaction Time Apparatus, Inco Ambala Ltd. (Accuracy΁0.001 s in a sitting position at Government Medical College and Hospital, Bhavnagar and at a Blind School, PNR campus, Bhavnagar, Gujarat, India. Observations / Results: Simple auditory reaction time response with four different type of sound (horn, bell, ring, and whistle was recorded in both groups. According to our study, there is no significant different in reaction time between congenital blind and normal healthy persons. Conclusion: Blind individuals commonly utilize tactual and auditory cues for information and orientation and they reliance on touch and audition, together with more practice in using these modalities to guide behavior, is often reflected in better performance of blind relative to sighted participants in tactile or auditory discrimination tasks, but there is not any difference in reaction time between congenitally blind and sighted people.

    Full Text Available Economic analysis is one way to determine the allocation of scarce resources for health-care programs. The initial step in this process is to estimate in economic terms the burden of diseases and the benefit from interventions for prevention and treatment of these diseases. In this paper, the direct and indirect economic loss due to blindness in India is calculated on the basis of certain assumptions. The cost of treating cataract blindness in India is estimated at current prices. The economic burden of blindness in India for the year 1997 based on our assumptions is Rs. 159 billion (US$ 4.4 billion, and the cumulative loss over lifetime of the blind is Rs. 2,787 billion (US$ 77.4 billion. Childhood blindness accounts for 28.7% of this lifetime loss. The cost of treating all cases of cataract blindness in India is Rs. 5.3 billion (US$ 0.15 billion. Similar estimates for causes of blindness other than cataract have to be made in order to develop a comprehensive approach to deal with blindness in India.

It is believed that the blind's superior performance is because of their efficient use of proprioceptive signals and...... environmental cues such as temperature and echolocation. We hypothesize that by limiting these cues, blind individuals will lose their advantage compared with controls in spatial navigation tasks. We therefore evaluated the performance of blind and sighted individuals in small-scale, tactile multiple T mazes.......

    Full Text Available Cryptography is increasingly applied to the E-commerce world, especially to the untraceable payment system and the electronic voting system. Protocols for these systems strongly require the anonymous digital signature property, and thus a blind signature strategy is the answer to it. Chaum stated that every blind signature protocol should hold two fundamental properties, blindness and intractableness. All blind signature schemes proposed previously almost are based on the integer factorization problems, discrete logarithm problems, or the quadratic residues, which are shown by Lee et al. that none of the schemes is able to meet the two fundamental properties above. Therefore, an ECC-based blind signature scheme that possesses both the above properties is proposed in this paper.

  9. Blindness in designing intelligent systems

    Denning, Peter J.

    1988-01-01

    New investigations of the foundations of artificial intelligence are challenging the hypothesis that problem solving is the cornerstone of intelligence. New distinctions among three domains of concern for humans--description, action, and commitment--have revealed that the design process for programmable machines, such as expert systems, is based on descriptions of actions and induces blindness to nonanalytic action and commitment. Design processes focusing in the domain of description are likely to yield programs like burearcracies: rigid, obtuse, impersonal, and unable to adapt to changing circumstances. Systems that learn from their past actions, and systems that organize information for interpretation by human experts, are more likely to be successful in areas where expert systems have failed.

    Full Text Available We focus on a form of joining conversations among multiple parties in service-oriented applications where a client may asynchronously join an existing conversation without need to know in advance any information about it. More specifically, we show how the correlation mechanism provided by orchestration languages enables a form of conversation joining that is completely transparent to clients and that we call 'blind-date joining'. We provide an implementation of this strategy by using the standard orchestration language WS-BPEL. We then present its formal semantics by resorting to COWS, a process calculus specifically designed for modelling service-oriented applications. We illustrate our approach by means of a simple, but realistic, case study from the online games domain.

  11. The PHENIX Hadron Blind Detector

    International Nuclear Information System (INIS)

    Dielectron measurements by the PHENIX Experiment at RHIC are limited by the combinatorial background from electrons and positrons which are not produced in the same pair. The Hadron Blind Detector will allow a substantial reduction of this background by correctly identifying dielectrons from photon conversions and pion Dalitz decays which dominate the signal in the low mass region of the spectrum. Triple GEM stacks, with a CsI photocathode deposited on the uppermost GEM, detect Cherenkov light produced by electrons in a CF4 radiator. The transparency of CF4, high quantum efficiency of CsI in the UV, and absence of a window between the gas radiator and the GEMs allow a large photoelectron yield, while minimizing the hadron signal. Results from the HBD in RHIC's Run-7 and preparations for upcoming runs are discussed.

    2012-04-01

    Full Text Available The aim of this paper is to develop a reliable and valid CRM (Customer relationship management scale specifically catering to Indian banking sector. An exhaustive review of literature on CRM was followed by depth interview and questionnaire survey. Exploratory factor analysis was followed by confirmatory factor analysis, which was presented in three forms; the single factor model, covariance model and the structural model. The covariance model shows CRM in Indian banking sector as a multidimensional construct comprising of fact ors namely organizational structure and customer support, service quality, trust, technology, personalization and market orientation. The structural model validates the previously extracted factors along with their indicators. The findings of this study validate the long held belief that CRM is a multidimensional construct and serves as a critical success factor for business performance. Since this study was conducted in context of Indian banking sector, the generalizability of the CRM scale has to be tested in other countries. A fair amount of literature on Indian banking sector dealt with identifying factors explaining the constructs of quality, value or satisfaction. But there is paucity of research pertaining to industry specific CRM scale development and validation. This study is an attempt to bridge this gap in the existing literature. It provides a conceptually validated CRM scale catering to Indian banking sector, which can help the managers in implementing the CRM in an effective manner and also can be used as a tool to identify the major areas requiring attention.

    Blind deconvolution is a classical image processing problem which has been investigated by a large number of researchers over the last four decades. The purpose of this monograph is not to propose yet another method for blind image restoration. Rather the basic issue of deconvolvability has been explored from a theoretical view point. Some authors claim very good results while quite a few claim that blind restoration does not work. The authors clearly detail when such methods are expected to work and when they will not. In order to avoid the assumptions needed for convergence analysis in the

  12. Blind extraction of exoplanetary spectra

    Science.gov (United States)

    Morello, Giuseppe; Waldmann, Ingo P.; Tinetti, Giovanna

    2016-06-01

    In the last decade, remote sensing spectroscopy enabled characterization of the atmospheres of extrasolar planets. Transmission and emission spectra of tens of transiting exoplanets have been measured with multiple instruments aboard Spitzer and Hubble Space Telescopes as well as ground-based facilities, revealing the presence of atomic, ionic and molecular species in their atmospheres, and constraining their temperature and pressure profiles.Early analyses were somehow heuristic both in measuring the spectra and in their interpretation, leading to some controversies in the literature.A photometric precision of 0.01% is necessary to detect the atmospheric spectral modulations. Current observatories, except Kepler, were not designed to achieve this precision. Data reduction is necessary to minimize the effect of instrument systematics in order to achieve the target precision. In the past, parametric models have extensively been used by most teams to remove correlated noise with the aid of auxiliary information of the instrument, the so-called optical state vectors (OSVs). Such OSVs can include inter- and intra-pixel position of the star or its spectrum, instrument temperatures and inclinations, and/or other parameters. In some cases, different parameterizations led to discrepant results.We recommend the use of blind non-parametric data detrending techniques to overcome those issues. In particular, we adopt Independent Component Analysis (ICA), i.e. a blind source separation (BSS) technique to disentangle the multiple instrument systematics and astrophysical signals in transit/eclipse light curves. ICA does not require a model for the systematics, and for this reason, it can be applied to any instrument with little changes, if any. ICA-based algorithms have been applied to Spitzer/IRAC and synthetic observations in photometry (Morello et al. 2014, 2015, 2016; Morello 2015) and to Hubble/NICMOS and Spitzer/IRS in spectroscopy (Waldmann 2012, 2014, Waldmann et al. 2013

  15. Iterated Gate Teleportation and Blind Quantum Computation.

    Science.gov (United States)

    Pérez-Delgado, Carlos A; Fitzsimons, Joseph F

    2015-06-01

    Blind quantum computation allows a user to delegate a computation to an untrusted server while keeping the computation hidden. A number of recent works have sought to establish bounds on the communication requirements necessary to implement blind computation, and a bound based on the no-programming theorem of Nielsen and Chuang has emerged as a natural limiting factor. Here we show that this constraint only holds in limited scenarios, and show how to overcome it using a novel method of iterated gate teleportations. This technique enables drastic reductions in the communication required for distributed quantum protocols, extending beyond the blind computation setting. Applied to blind quantum computation, this technique offers significant efficiency improvements, and in some scenarios offers an exponential reduction in communication requirements. PMID:26196609

    Full Text Available Facial melanoses (FM are a common presentation in Indian patients, causing cosmetic disfigurement with considerable psychological impact. Some of the well defined causes of FM include melasma, Riehl′s melanosis, Lichen planus pigmentosus, erythema dyschromicum perstans (EDP, erythrosis, and poikiloderma of Civatte. But there is considerable overlap in features amongst the clinical entities. Etiology in most of the causes is unknown, but some factors such as UV radiation in melasma, exposure to chemicals in EDP, exposure to allergens in Riehl′s melanosis are implicated. Diagnosis is generally based on clinical features. The treatment of FM includes removal of aggravating factors, vigorous photoprotection, and some form of active pigment reduction either with topical agents or physical modes of treatment. Topical agents include hydroquinone (HQ, which is the most commonly used agent, often in combination with retinoic acid, corticosteroids, azelaic acid, kojic acid, and glycolic acid. Chemical peels are important modalities of physical therapy, other forms include lasers and dermabrasion.

    2013-01-01

    Full Text Available Purpose: To determine the causes of childhood blindness and severe visual impairment in pupils attending schools for the blind in Burundi in order to assist planning for services in the country. Materials and Methods: All pupils attending three schools for the blind in Burundi were examined. A modified WHO/PBL eye examination record form for children with blindness and low vision was used to record the findings. Data was analyzed for those who became blind or severely visually impaired before the age of 16 years. Results: Overall, 117 pupils who became visually impaired before 16 years of age were examined. Of these, 109 (93.2% were blind or severely visually impaired. The major anatomical cause of blindness or severe visual impairment was cornea pathology/phthisis (23.9%, followed by lens pathology (18.3%, uveal lesions (14.7% and optic nerve lesions (11.9%. In the majority of pupils with blindness or severe visual impairment, the underlying etiology of visual loss was unknown (74.3%. More than half of the pupils with lens related blindness had not had surgery; among those who had surgery, outcomes were generally poor. Conclusion: The causes identified indicate the importance of continuing preventive public health strategies, as well as the development of specialist pediatric ophthalmic services in the management of childhood blindness in Burundi. The geographic distribution of pupils at the schools for the blind indicates a need for community-based programs to identify and refer children in need of services.

    Despite the well-established finding that American Indian adolescents are at a greater risk of illicit substance use and abuse than the general population, few generalist explanations of deviance have been extended to American Indian substance use. Using a popular generalist explanation of deviance, General Strain Theory, we explore the predictive utility of this model with a subsample of American Indian adolescents from waves one and two of the National Longitudinal Study of Adolescent Health (Add-Health). Overall, we find mixed support for the utility of General Strain Theory to account for American Indian adolescent substance use. While exposure to recent life events, a common measure of stress exposure, was found to be a robust indicator of substance use, we found mixed support for the thesis that negative affect plays a key role in mediating the link between strain and substance use. However, we did find evidence that personal and social resources serve to condition the link between stress exposure and substance use, with parental control, self-restraint, religiosity, and exposure to substance using peers each serving to moderate the association between strain and substance use, albeit in more complex ways than expected.

    American Indians are disproportionately burdened by alcohol-related problems. Yet, research exploring predictors of alcohol use among American Indians has been limited by cross-sectional designs and reservation-based samples. Guided by a life course developmental perspective, the current study used a subsample of American Indians (n=927) from the National Longitudinal Study of Adolescent Health (Add Health) to explore alcohol use (current drinking, usual number of drinks, and binge drinking) among this population. We examined whether adult social roles (i.e., cohabitation, marriage, parenthood, college enrollment, and full-time work) were linked to the rise and fall of alcohol use. Multi-level models demonstrated that adult social roles were linked to alcohol use at the within- and between-person levels. Becoming a parent was linked to a lower likelihood of being a current drinker, fewer alcoholic drinks, and less frequent binge drinking. Transitioning to full-time work was associated with a higher likelihood of being a current drinker and more frequent binge drinking. Results point to the importance of exploring within-group trajectories of alcohol use and highlight the protective and risky nature of adult social roles among American Indians. PMID:24857795

    India suffers from major heatwaves during March-June. The rising trend of number of intense heatwaves in recent decades has been vaguely attributed to global warming. Since the heat waves have a serious effect on human mortality, root causes of these heatwaves need to be clarified. Based on the observed patterns and statistical analyses of the maximum temperature variability, we identified two types of heatwaves. The first-type of heatwave over the north-central India is found to be associated with blocking over the North Atlantic. The blocking over North Atlantic results in a cyclonic anomaly west of North Africa at upper levels. The stretching of vorticity generates a Rossby wave source of anomalous Rossby waves near the entrance of the African Jet. The resulting quasi-stationary Rossby wave-train along the Jet has a positive phase over Indian subcontinent causing anomalous sinking motion and thereby heatwave conditions over India. On the other hand, the second-type of heatwave over the coastal eastern India is found to be due to the anomalous Matsuno-Gill response to the anomalous cooling in the Pacific. The Matsuno-Gill response is such that it generates northwesterly anomalies over the landmass reducing the land-sea breeze, resulting in heatwaves.

    Neuman [1] has made an ambitious attempt to integrate perspectives on the psychology of personality that usually run in parallel. The field calls to mind the fable of the blind men and the elephant: each perspective makes different claims about the person based on the aspect it apprehends. Neuman links cognition, affective neuroscience and psychodynamics in a bold effort to sketch the entire beast. However, his hefty framework has some elephantine elements, and is at times conceptually loose and baggy.

    As the volume of electronically available information grows, relevant items become harder to find. This work presents an approach to personalizing search results in scientific publication databases. This work focuses on re-ranking search results from existing search engines like Solr or ElasticSearch. This work also includes the development of Obelix, a new recommendation system used to re-rank search results. The project was proposed and performed at CERN, using the scientific publications available on the CERN Document Server (CDS). This work experiments with re-ranking using offline and online evaluation of users and documents in CDS. The experiments conclude that the personalized search result outperform both latest first and word similarity in terms of click position in the search result for global search in CDS.

    The MicroPLB (personal locator beacon) is a search and rescue satellite-aided tracking (SARSAT) transmitter. When activated it emits a distress signal to a constellation of internationally operated satellites. The endangered person's identity and location anywhere on Earth is automatically forwarded to central monitoring stations around the world. It is accurate to within just a few meters. The user uses the device to download navigation data from a global positioning satellite receiver. After the download is complete, the MicroPLB functions as a self-locating beacon. Also, it is the only PLB to use a safe battery. In the past, other PLB devices have used batteries that have enough volatility to explode with extreme force. It was developed by Microwave Monolithic, Inc. through SBIR funding from Glenn Research Center and Goddard Space Flight Center.

  19. Renewable energy in Indian country

    Energy Technology Data Exchange (ETDEWEB)

    NONE

    1995-12-31

    On June 25--27, 1995, at Mesa Verde National Park in southwestern Colorado, the Center for Resource Management (CRM), organized and sponsored a conference in conjunction with the Navajo Nation, EPA, and Bechtel Group, Inc., to deal with issues associated with developing renewable energy resources on Indian lands. Due to the remoteness of many reservation homes and the cost of traditional power line extensions, a large percentage of the Indian population is today without electricity or other energy services. In addition, while they continue to develop energy resources for export, seeing only minimal gain in their own economies, Indian people are also subject to the health and environmental consequences associated with proximity to traditional energy resource development. Renewable energy technologies, on the other hand, are often ideally suited to decentralized, low-density demand. These technologies--especially solar and wind power--have no adverse health impacts associated with generation, are relatively low cost, and can be used in applications as small as a single home, meeting power needs right at a site. Their minimal impact on the environment make them particularly compatible with American Indian philosophies and lifestyles. Unfortunately, the match between renewable energy and Indian tribes has been hampered by the lack of a comprehensive, coordinated effort to identify renewable energy resources located on Indian lands, to develop practical links between Indian people`s needs and energy producers, and to provide the necessary training for tribal leaders and members to plan, implement, and maintain renewable energy systems. Summaries of the presentations are presented.

    Debilitating ocular pain poses a significant challenge to the ophthalmologist. When the pain is intractable and the eye has very poor vision and is disfigured, surgical removal of the eye has traditionally been the definitive treatment of choice. Because many people are uncomfortable psychologically with removal of their eye, however painful, and other patients are not good surgical candidates, an alternative to enucleation is sometimes warranted, and injection of a neurolytic substance can often induce long-lasting anesthesia for a blind painful eye. This article reviews a range of options for management of blind painful eye from anesthesia to enucleation. PMID:16701166

    This paper applies blind source separation or independent component analysis for images that may contain mixtures of text, audio, or other images for steganography purposes. The paper focuses on separating mixtures in the transform domain such as Fourier domain or the Wavelet domain. The study addresses the effectiveness of steganography when using linear mixtures of multimedia components and the ability of standard blind sources separation techniques to discern hidden multimedia messages. Mixing in the space, frequency, and wavelet (scale) domains is compared. Effectiveness is measured using mean square error rate between original and recovered images.

  7. Suicidal behavior in Indian adolescents.

    Suicide is both a public and mental health problem, and is a leading cause of deaths, especially among adolescents. Two factors that contribute to the decision of adolescents to commit suicide are having a primary mood disorder and/or substance use. In the Indian culture, the family unit has both a positive and negative impact on suicide. The family serves as a protective factor that provides a strong support for the individual, but alternately creates an inseparable individual when seeking mental health care, which often complicates the situation. Due to the stigma, Indians typically perceive having a mental illness as shameful. Religion is integral to the Indian culture so much so that individuals often use herbal remedies, seek help from religious leaders, and attend religious establishments prior to obtaining a mental health evaluation in those that are subsequently deemed as mentally ill. Despite the fact that suicides are underreported and misdiagnosed in India, it is known that the highest rates are among those immigrating, Indians tend to switch the methods they use to commit suicide from ingestion of poison to hanging, which may reflect a lack of available poisonous substances or the influence of the host culture. Considering the high suicide rates in adolescents, the importance of providing psychoeducation, restricting access to lethal means, and promoting social integration in immigrants are various ways by which suicides in Indian adolescents can be avoided.

    Full Text Available In King Oedipus (429 B.C.E by Sophocles and Death of a Salesman (1949 A.D by Arthur Miller, the central characters Oedipus and Willy Loman take extreme pride in their professions; their pride blinds them from seeing the reality of their circumstances, and it eventually brings their ruin. At he same time, the other characters also display their figurative blindness in both the tragedies. However, it is demonstrated that the protagonists do not succeed in executing their responsibilities as leaders and instead encircle themselves with personal conflicts, which affect their families and others. They strive to rise above their problems with a view to avoiding any possibility of failure. Accordingly, they imbibe willingness in their nature to bring happiness in their plain lives. Ironically, just like Oedipus, Willy Loman never realises the full truth of himself and goes through his life in a blind manner.Keywords: American Dream, blindness, false pride, hamartia, intentional delay of vision, reality, second conscience

    The universal blind quantum computation (UBQC) protocol [A. Broadbent, J. Fitzsimons, and E. Kashefi, in Proceedings of the 50th Annual IEEE Symposiumon Foundations of Computer Science (IEEE Computer Society, Los Alamitos, CA, USA, 2009), pp. 517-526.] allows a client to perform quantum computation on a remote server. In an ideal setting, perfect privacy is guaranteed if the client is capable of producing specific, randomly chosen single qubit states. While from a theoretical point of view, this may constitute the lowest possible quantum requirement, from a pragmatic point of view, generation of such states to be sent along long distances can never be achieved perfectly. We introduce the concept of ɛ blindness for UBQC, in analogy to the concept of ɛ security developed for other cryptographic protocols, allowing us to characterize the robustness and security properties of the protocol under possible imperfections. We also present a remote blind single qubit preparation protocol with weak coherent pulses for the client to prepare, in a delegated fashion, quantum states arbitrarily close to perfect random single qubit states. This allows us to efficiently achieve ɛ-blind UBQC for any ɛ>0, even if the channel between the client and the server is arbitrarily lossy.

  7. Wavelet Coherence Analysis of Change Blindness

    2013-01-01

    Full Text Available Change blindness is the incapability of the brain to detect substantial visual changes in the presence of other visual interruption. The objectives of this study are to examine the EEG (Electroencephalographic based changes in functional connectivity of the brain due to the change blindness. The functional connectivity was estimated using the wavelet-based MSC (Magnitude Square Coherence function of ERPs (Event Related Potentials. The ERPs of 30 subjects were used and were recorded using the visual attention experiment in which subjects were instructed to detect changes in visual stimulus presented before them through the computer monitor. The two-way ANOVA statistical test revealed significant increase in both gamma and theta band MSCs, and significant decrease in beta band MSC for change detection trials. These findings imply that change blindness might be associated to the lack of functional connectivity in gamma and theta bands and increase of functional connectivity in beta band. Since gamma, theta, and beta frequency bands reflect different functions of cognitive process such as maintenance, encoding, retrieval, and matching and work load of VSTM (Visual Short Term Memory, the change in functional connectivity might be correlated to these cognitive processes during change blindness.

  11. Creative thought as blind-variation and selective-retention: Combinatorial models of exceptional creativity

    Science.gov (United States)

    Simonton, Dean Keith

    2010-06-01

    Campbell (1960) proposed that creative thought should be conceived as a blind-variation and selective-retention process (BVSR). This article reviews the developments that have taken place in the half century that has elapsed since his proposal, with special focus on the use of combinatorial models as formal representations of the general theory. After defining the key concepts of blind variants, creative thought, and disciplinary context, the combinatorial models are specified in terms of individual domain samples, variable field size, ideational combination, and disciplinary communication. Empirical implications are then derived with respect to individual, domain, and field systems. These abstract combinatorial models are next provided substantive reinforcement with respect to findings concerning the cognitive processes, personality traits, developmental factors, and social contexts that contribute to creativity. The review concludes with some suggestions regarding future efforts to explicate creativity according to BVSR theory.

    Full Text Available There are 50 million people living with epilepsy worldwide, and most of them reside in developing countries. About 10 million persons with epilepsy are there in India. Many people with active epilepsy do not receive appropriate treatment for their condition, leading to large treatment gap. The lack of knowledge of antiepileptic drugs, poverty, cultural beliefs, stigma, poor health infrastructure, and shortage of trained professionals contribute for the treatment gap. Infectious diseases play an important role in seizures and long-term burden causing both new-onset epilepsy and status epilepticus. Proper education and appropriate health care services can make tremendous change in a country like India. There have been many original researches in various aspects of epilepsy across India. Some of the geographically specific epilepsies occur only in certain regions of our country which have been highlighted by authors. Even the pre-surgical evaluation and epilepsy surgery in patients with drug-resistant epilepsy is available in many centers in our country. This article attempts to provide a complete preview of epilepsy in India.

    Full Text Available Personality is said to be the product of genes and environmental factors. Amid several environmental factors, culture seems to play an imperative role in shaping ones behavior. Studying the influence of culture on organizational behavior from heterogeneity perspective has become a predominant factor among the eminent researchers and academicians. Since it has been frequently stated that Indian studies are seems to be contradictory and inconsistent in its cultural study, this paper tries to address the difference between South Indian managers and other than south Indian Managers on their value systems and their Conflict management Style. T test and one way Anova are the statistical tests used to infer the collected data. Result shows that there is no major significant differences with respective to individual values exist between the south Indian and other than south Indian Managers except with the value system of Conformity at 1 per cent level of significance, where south Indian manager are seems to be somewhat traditional when compare to managers hail from other than south India and more over they are seems to be having withdrawal style of conflict management. There is no significant difference seems to exist among these managers with respect to other conflict management styles. Influence of years of stay away from birth place has also been analyzed where it shows external exposure has its influence on individual value.

    Full Text Available In his entertaining 1986 book, The Real Coke, the Real Story, Thomas Oliver tells the story of the now infamous “New Coke”, a story retold in Malcolm Gladwell’s (2005 best-seller Blink. In the early 1980s, Pepsi began running commercials in which people took a sip from two glasses, not knowing which was Coke and which Pepsi. The majority preferred Pepsi. The Coca-Cola Company replicated these blind taste-tests and found the same result. Losing market share, Coke—long the dominant brand—changed its old formula and came out with “New Coke”, a soda made to a new formula, one that in a new round of blind taste-tests came out above Pepsi. But New Coke was a disaster.Consumers hated it. Coke not only returned to its old formula, but Pepsi never did overtake Coke, which remains today the dominant brand world-wide.

    A 35-year-old female with a known medical history of cystic fibrosis was admitted to our institution for massive hemoptysis. CTA depicted a hypertrophied bronchial artery to the right upper lobe and showed signs of recent bleeding at that location. Bronchial artery embolization (BAE) was performed with gelfoam slurry, because pronounced shunting to the pulmonary artery was present. Immediately after BAE, the patient developed bilateral cortical blindness. Control angiography showed an initially not opacified anastomosis between the embolized bronchial artery and the right subclavian artery, near to the origin of the right vertebral artery. Cessation of outflow in the bronchial circulation reversed the flow through the anastomosis and allowed for spill of embolization material into the posterior circulation. Unfortunately the cortical blindness presented was permanent.

  5. Latent Images, Blind Comments on Photography

    Directory of Open Access Journals (Sweden)

    Jenny Feray

    2013-12-01

    Full Text Available Photographs, or images as the final result of a process, merely mark out the moment when the eye is helplessly limited to what it sees. Thus, what escapes the eye in the physical sense, i.e. what the eye will never see, is what occurs before the product- image, within the act itself. The latent image, the desire-image, unfolds throughout the duration of the photographic act. When the picture is ‘taken’, then the desire subsides until the next desire for another image arises. Based on the photographic experiment by Jerry Chan, member of a group of blind people, this article aims at rethinking the photographic act as the real- life experience of an impression process, leading the blind apprentice photographer to experience sightedness within his very flesh.

    CERN Document Server

    Aschwanden, Markus J; Malanushenko, Anna

    2015-01-01

    We test the feasibility of 3D coronal-loop tracing in stereoscopic EUV image pairs, with the ultimate goal of enabling efficient 3D reconstruction of the coronal magnetic field that drives flares and coronal mass ejections (CMEs). We developed an automated code designed to perform triangulation of coronal loops in pairs (or triplets) of EUV images recorded from different perspectives. The automated (or blind) stereoscopy code includes three major tasks: (i) automated pattern recognition of coronal loops in EUV images, (ii) automated pairing of corresponding loop patterns from two different aspect angles, and (iii) stereoscopic triangulation of 3D loop coordinates. We perform tests with simulated stereoscopic EUV images and quantify the accuracy of all three procedures. In addition we test the performance of the blind stereoscopy code as a function of the spacecraft-separation angle and as a function of the spatial resolution. We also test the sensitivity to magnetic non-potentiality. The automated code develo...

  7. Blind Estimation of Multiple Carrier Frequency Offsets

    CERN Document Server

    Yu, Yuanning; Poor, H Vincent; Koivunen, Visa

    2007-01-01

    Multiple carrier-frequency offsets (CFO) arise in a distributed antenna system, where data are transmitted simultaneously from multiple antennas. In such systems the received signal contains multiple CFOs due to mismatch between the local oscillators of transmitters and receiver. This results in a time-varying rotation of the data constellation, which needs to be compensated for at the receiver before symbol recovery. This paper proposes a new approach for blind CFO estimation and symbol recovery. The received base-band signal is over-sampled, and its polyphase components are used to formulate a virtual Multiple-Input Multiple-Output (MIMO) problem. By applying blind MIMO system estimation techniques, the system response is estimated and used to subsequently transform the multiple CFOs estimation problem into many independent single CFO estimation problems. Furthermore, an initial estimate of the CFO is obtained from the phase of the MIMO system response. The Cramer-Rao Lower bound is also derived, and the la...

  8. Emergence of Blind Areas in Information Spreading

    CERN Document Server

    Zhang, Zi-Ke; Han, Xiao-Pu; Liu, Chuang

    2013-01-01

    Recently, contagion-based (disease, information, etc.) spreading on social networks has been extensively studied. In this paper, other than traditional full interaction, we propose a partial interaction based spreading model, considering that the informed individuals would transmit information to only a certain fraction of their neighbors due to the transmission ability in real-world social networks. Simulation results on three representative networks (BA, ER, WS) indicate that the spreading efficiency is highly correlated with the network heterogeneity. In addition, a special phenomenon, namely \\emph{Information Blind Areas} where the network is separated by several information-unreachable clusters, will emerge from the spreading process. Furthermore, we also find that the size distribution of such information blind areas obeys power-law-like distribution, which has very similar exponent with that of site percolation. Detailed analyses show that the critical value is decreasing along with the network heterog...

  9. Multiple Blind Beamforming Based on LSCMA

    Science.gov (United States)

    Guo, Yan; Li, Ning; Lim, Myoung-Seob; Wang, Jin-Long

    Blind beamforming plays an important role in multiple-input multiple-output (MIMO) Systems, radar, cognitive radio, and system identification. In this paper, we propose a new algorithm for multiple blind beamforming algorithm based on the least square constant modulus algorithm (LSCMA). The new method consists of the following three parts: (a) beamforming of one signal with LSCMA. (b) direction-of-arrival (DOA) estimation of the remaining signals by rooting the weight vector polynomial. (c) beamforming of the remaining signals with linear constraints minimum variance (LCMV) method. After the convergence of LSCMA, one signal is captured and the arrival angles of the remaining signals can be obtained by rooting the weight vector polynomial. Therefore, beamforming can be quickly established for the remaining signals using LCMV method. Simultaneously the DOA of the signals can also be obtained. Simulation results show the performance of the presented method.

    Full Text Available The research carried out in Juiz de Fora, MG, Brazil, intended at investigating, together with men and women who suffer from congenital visual impairment, how they felt about diversity, body image, self-esteem and vanity. The investigation of autobiographical accounts was the option for this study. Initially, 20 (twenty interviews were analyzed and 6 (six autobiographical accounts, selected from the peculiarities of each single interviewee – each one containing his/her single life lessons - followed suit. The conclusion reached is that the subjects had undergone an exhausting process of acceptance of their own impairment. If, on the one hand, the blindness comes with angst, uncertainties, and many difficulties, on the other hand, these circumstances lead the blind to face the ups and downs of life with courage, determination and will to live. Surprisingly, in the study the body was not approached at a source of concern or are which should be emphasized.

CTA depicted a hypertrophied bronchial artery to the right upper lobe and showed signs of recent bleeding at that location. Bronchial artery embolization (BAE) was performed with gelfoam slurry, because pronounced shunting to the pulmonary artery was present. Immediately after BAE, the patient developed bilateral cortical blindness. Control angiography showed an initially not opacified anastomosis between the embolized bronchial artery and the right subclavian artery, near to the origin of the right vertebral artery. Cessation of outflow in the bronchial circulation reversed the flow through the anastomosis and allowed for spill of embolization material into the posterior circulation. Unfortunately the cortical blindness presented was permanent

    The mobility of the blind and visually impaired is associated with many barriers and risks. To secure crossings, signalized intersections are partially equipped with acoustic or tactile indicators. However, environmental conditions might interfere with the acoustic identification of the green time. Furthermore, information such as intersection topology, bicycle traffic or the curb structure is not accessible to visually impaired road users. Therefore, most trips are limited to trained routes....

    During development of a Venetian Blind polarizer, high reflections and substantial pattern deformation were noted. Analysis showed that when the polarizer was illuminated slightly off axis, a degenerate mode was excited. This mode is resonant at the design center frequency, and was the cause of the problems. A design developed using dual vanes has been shown to be free of the problem. It also has greater bandwidth.

    This paper focuses on the blind image separation using sparse representation for natural images. The statistics of the natural image is based on one particular statistical property called sparseness, which is closely related to the super-gaussian distribution. Since natural images can have both gaussian and non gaussian distribution, the original infomax algorithm cannot be directly used for source separation as it is better suited to estimate the super-gaussian sources. Hence, we explore the...

    This paper presents an algorithm for blind recognition of punctured convolutional codes which is an important problem in adaptive modulation and coding. For a given finite sequence of convolutional code, the parity check matrix of the convolutional code is first computed by solving a linear system with adequate error tolerance. Then a minimal basic encoding matrix of the original convolutional code and its puncturing pattern are determined according to the known parity check matrix of the punctured convolutional code.

  6. Indian gatekeepers of foreign journals: A preliminary analysis

    2013-01-01

    Full Text Available In recent years, efforts have been made to quantify and measure various aspects of performance of a country by measuring both the quantity and quality of research. Recently, a new science indicator has been introduced of named as the "gatekeepers" or "members of editorial boards" to investigate the scientific/technological contribution of a country. The editorial boards of scientific journals play a crucial role in science by helping to guarantee the quality and relevance of the research eventually published. Besides, it can be assumed the presence on an editorial board of persons of a given nationality can influence the scientific output of their country, which could be made more visible. Until date, little explicit attention has been given to editorial board memberships of Indians despite such appointments being generally regarded as representing evidence of significant scholarship and research achievement by individual academics. The objective of this research is to contribute data on patterns of editorial board membership of Indian academics and journals. Specifically, we examine the composition and concentration of individuals on editorial boards in academic journals with high rankings. The study contributes to the best of our knowledge of Indian contribution in influencing the research at international level by means of gate-keeping.

  7. A Completely Blind Video Integrity Oracle.

    2016-01-01

    Considerable progress has been made toward developing still picture perceptual quality analyzers that do not require any reference picture and that are not trained on human opinion scores of distorted images. However, there do not yet exist any such completely blind video quality assessment (VQA) models. Here, we attempt to bridge this gap by developing a new VQA model called the video intrinsic integrity and distortion evaluation oracle (VIIDEO). The new model does not require the use of any additional information other than the video being quality evaluated. VIIDEO embodies models of intrinsic statistical regularities that are observed in natural vidoes, which are used to quantify disturbances introduced due to distortions. An algorithm derived from the VIIDEO model is thereby able to predict the quality of distorted videos without any external knowledge about the pristine source, anticipated distortions, or human judgments of video quality. Even with such a paucity of information, we are able to show that the VIIDEO algorithm performs much better than the legacy full reference quality measure MSE on the LIVE VQA database and delivers performance comparable with a leading human judgment trained blind VQA model. We believe that the VIIDEO algorithm is a significant step toward making real-time monitoring of completely blind video quality possible. PMID:26599970

    Corona is one of important reasons of electrical energy loss in the electric power. According to incomplete statistics, corona loss electrical energy has achieved two thousands and fifty millions kW.h in our nation every year. Sometimes corona also can have some disturbance to radio and communication. Therefore to discover and examine corona promptly has the extremely vital significance for conserving energy and realizing high quality communication. Ultraviolet image detecting technology is a preferred corona detection method in electric power. It may realize all-weather reliable survey to corona. The solar blind ultraviolet signal discharged by corona is quite weak. Moreover the ultraviolet image quality has been affected seriously by the detection system noise. A corona solar blind ultraviolet image processing method is proposed in this paper. Ultraviolet image has so small target, low contrast image, district characteristic and real-time demand that it is processed by multi-scale ultraviolet morphology filter technology based on mathematics morphology in this paper. Results show that the method can stretch image contrast, enhance target and weaken noise. The algorithm is easy to deal in parallel and it can be realized easily by hardware. It will be accurately demarcated when the condition of device need to be absolutely measured. The paper proposes a kind of mathematics morphology algorithm. Solar blind ultraviolet image will be further processed according to temperature and humidity in order to remove the infection of corona discharge demarcation and solve correct demarcation question when equipment condition need to be absolutely measured.

    Full Text Available The number of users making online transactions has registered a strong growth in the recent past. In today's world of globalisation, expansion of business is possible through internet. Understanding the behaviour of online consumers is crucial for business enterprises to grow. Hence the study aims to examine the behaviour of the online users engaged in Business to Consumer (B2C E-commerce. A questionnaire based survey is used to examine the most conducted and recommended online activities; their preferred reasons; modes of online payment; factors limiting the popularity of online transactions and features enhancing the quality of an online experience. The survey findings indicate booking travel tickets online as the most conducted and the recommended online activity in India and time saving as the most important reason for conducting these transactions. Indian consumers consider risk of theft of personal/banking information and inability to assess the quality of product as the two important factors limiting the popularity of online transactions and a more secure website as the most significant feature for a better online experience.

  10. Experiences of childbirth in Natal Indian women

    H.B. Brookes

    1991-09-01

    Full Text Available Through fifteen in-depth case studies of primipara, Natal Indian women’s experiences of childbirth have been described Common problems were identified, including lack of a family support person throughout labour, lithotomy position for delivery, episiotomies and their sequelae, breast-feeding difficulties and lack of professional support in the early puerperium at home. Preparation for common medical interventions in labour, breast-feeding and parenting appeared inadequate. Pertinent sociocultural aspects have been identified. These include continuing family support and culturally prescribed behaviour pertaining most importantly to the early puerperium and affecting the maternal-neonatal dyad. In the early adaptation to motherhood informants continued their role as daughter or daughter-in-law and would only actively continue their role as wife later or at the end of the puerperium. These traditional patterns of behaviour persist despite marked changes in educational level, language spoken and employment status. In the light of this research and founded on scientific evidence, a number of recommendations are made and areas for further research are identified

    Margo, Curtis E; Harman, Lynn E; Smith, Don B

    2013-01-01

    Several months after anonymously publishing an essay in 1749 with the title "Letter on the Blind for the Use of Those Who Can See," the chief editor of the French Encyclopédie was arrested and taken to the prison fortress of Vincennes just east of Paris, France. The correctly assumed author, Denis Diderot, was 35 years old and had not yet left his imprint on the Age of Enlightenment. His letter, which recounted the life of Nicolas Saunderson, a blind mathematician, was intended to advance secular empiricism and disparage the religiously tinged rationalism put forward by Rene Descartes. The letter's discussion of sensory perception in men born blind dismissed the supposed primacy of visual imagery in abstract thinking. The essay did little to resolve any philosophical controversy, but it marked a turning point in Western attitudes toward visual disability. PMID:23307219

    Purpose To identify independent risk factors for incident visual impairment (VI) and monocular blindness. Design Population-based prospective cohort study. Participants 4,658 Latinos aged 40 years in the Los Angeles Latino Eye Study (LALES) Methods A detailed history and comprehensive ophthalmological examination was performed at baseline and at the 4-year follow-up on 4,658 Latinos aged 40 years and older from Los Angeles, California. Incident VI was defined as best corrected visual acuity (BCVA) of 20/200 in the better-seeing eye at the 4 year follow-up examination in persons who had a BCVA of ≥20/40 in the better seeing eye at baseline. Incident monocular blindness was defined as BCVA of ≤20/200 in one eye at follow-up in persons who had a BCVA >20/200 in both eyes at baseline. Socio-demographic and clinical risk factors identified at the baseline interview and examination and associated with incident VI and loss of vision were determined using multivariable regression. Odds ratios (OR) were calculated for those variables that were independently associated with visual impairment and monocular blindness. Main Outcome Measures ORs for various risk factors for incident VI and monocular blindness Results Independent risk factors for incident VI were older age (70–79 years OR=4.8, ≥80 years OR=17.9), being unemployment (OR=3.5), and having diabetes mellitus (OR=2.2). Independent risk factors for monocular blindness were being retired (OR=3.4) or widowed (OR=3.7), having diabetes mellitus (OR=2.1) or any ocular disease (OR=5.6) at baseline. Persons with self-reported excellent/good vision were less likely to develop VI or monocular blindness (OR=0.4–0.5). Conclusion Our data highlight that older Latinos and Latinos with diabetes mellitus or self-reported eye diseases are at high risk of developing vision loss. Furthermore, being unemployed, widowed or retired confers an independent risk of monocular blindness. Interventions that prevent, treat, and focus on

  5. A NEW EFFICIENT ID-BASED PROXY BLIND SIGNATURE SCHEME

    Institute of Scientific and Technical Information of China (English)

    Ming Yang; Wang Yumin

    2008-01-01

    In a proxy blind signature scheme, the proxy signer is allowed to generate a blind signature on behalf of the original signer. The proxy blind signature scheme is useful in several applications such as e-voting, e-payment, etc. Recently, Zheng, et al. presented an IDentity (ID)-based proxy blind signature. In this paper, a new efficient ID-based proxy blind signature scheme from bilinear pairings is proposed, which can satisfy the security properties of both the proxy signatures and the blind signature schemes. Analysis of the scheme efficiency shows that the new scheme is more efficient than Zheng, et al.'s scheme. The proposed scheme is more practical in the real world.

    2004-01-01

    This paper proposes a new untraceable Partially Blind Signature scheme which is a cross between the traditional signature scheme and the blind signature scheme. In this proposed scheme, the message M that the signer signed can be divided into two parts. The first part can be known to the signer (like that in the traditional signature scheme) while the other part cannot be known to the signer (like that in the blind signature scheme). After having signed M, the signer cannot determine if he has made the signature of M except through the part that he knows. We draw ideas from Brands' "Restricted Blind Signature" to solve the Untraceable Partially Blind Signature problem. Our scheme is a probabilistic signature scheme and the security of our Untraceable Partially Blind Signature scheme relies on the difficulty of computing discrete logarithm.

    In the congenitally blind (CB), sensory deprivation results in cross-modal plasticity, with visual cortical activity observed for various auditory tasks. This reorganization has been associated with enhanced auditory abilities and the recruitment of visual brain areas during sound and language processing. The questions we addressed are whether visual cortical activity might also be observed in CB during passive listening to auditory speech and whether cross-modal plasticity is associated with adaptive differences in neuronal populations compared to sighted individuals (SI). We focused on the neural substrate of vowel processing in CB and SI adults using a repetition suppression (RS) paradigm. RS has been associated with enhanced or accelerated neural processing efficiency and synchronous activity between interacting brain regions. We evaluated whether cortical areas in CB were sensitive to RS during repeated vowel processing and whether there were differences across the two groups. In accordance with previous studies, both groups displayed a RS effect in the posterior temporal cortex. In the blind, however, additional occipital, temporal and parietal cortical regions were associated with predictive processing of repeated vowel sounds. The findings suggest a more expanded role for cross-modal compensatory effects in blind persons during sound and speech processing and a functional transfer of specific adaptive properties across neural regions as a consequence of sensory deprivation at birth.

  16. Blind estimation of compartmental model parameters

    International Nuclear Information System (INIS)

    Computation of physiologically relevant kinetic parameters from dynamic PET or SPECT imaging requires knowledge of the blood input function. This work is concerned with developing methods to accurately estimate these kinetic parameters blindly; that is, without use of a directly measured blood input function. Instead, only measurements of the output functions - the tissue time-activity curves - are used. The blind estimation method employed here minimizes a set of cross-relation equations, from which the blood term has been factored out, to determine compartmental model parameters. The method was tested with simulated data appropriate for dynamic SPECT cardiac perfusion imaging with 99mTc-teboroxime and for dynamic PET cerebral blood flow imaging with 15O water. The simulations did not model the tomographic process. Noise levels typical of the respective modalities were employed. From three to eight different regions were simulated, each with different time-activity curves. The time-activity curve (24 or 70 time points) for each region was simulated with a compartment model. The simulation used a biexponential blood input function and washin rates between 0.2 and 1.3 min-1 and washout rates between 0.2 and 1.0 min-1. The system of equations was solved numerically and included constraints to bound the range of possible solutions. From the cardiac simulations, washin was determined to within a scale factor of the true washin parameters with less than 6% bias and 12% variability. 99mTc-teboroxime washout results had less than 5% bias, but variability ranged from 14% to 43%. The cerebral blood flow washin parameters were determined with less than 5% bias and 4% variability. The washout parameters were determined with less than 4% bias, but had 15-30% variability. Since washin is often the parameter of most use in clinical studies, the blind estimation approach may eliminate the current necessity of measuring the input function when performing certain dynamic studies

    We investigate the nonlinear blind equalization for volume holographic data storage channel. Base on the recurrent neural network channel model, we describe a novel blind equalizer for the volume holographic data storage system to improve the bit error rate and hence to make the storage densities achievable. The experimental results also indicate that a significant improvement in the bit error rate to 2.55 × 10-3 is possible with the nonlinear blind equalization.

    2004-01-01

    An iterative separation approach, i.e. source signals are extracted and removed one by one, is proposed for multichannel blind deconvolution of colored signals. Each source signal is extracted in two stages: a filtered version of the source signal is first obtained by solving the generalized eigenvalue problem, which is then followed by a single channel blind deconvolution based on ensemble learning. Simulation demonstrates the capability of the approach to perform efficient mutichannel blind deconvolution.

    Plasticity in the visual cortex of blind individuals provides a rare window into the mechanisms of cortical specialization. In the absence of visual input, occipital (“visual”) brain regions respond to sound and spoken language. Here, we examined the time course and developmental mechanism of this plasticity in blind children. Nineteen blind and 40 sighted children and adolescents (4–17 years old) listened to stories and two auditory control conditions (unfamiliar foreign speech, and music). ...

    We discuss the challenge high school teachers face when teaching physics to the blind. Using the oral history method, we interview physics teachers who have dealt with the inclusion of blind students in regular classrooms. Based on our study, we find that the performance of these students varies, depending on the studied subject. The narrative makes clear the teachers' lack of preparation to deal with inclusion, and their search for alternative methods to improve blind students' learning.

    When engaged in an attention demanding task, people are surprisingly vulnerable to inattentional blindness, the failure to notice an unexpected event. Two theories of cognitive aging, attentional capacity models and inhibitory deficit models, make opposite predictions about age differences in susceptibility to inattentional blindness. We tested these predictions using an inattentional blindness paradigm developed by Simons and Chabris (1999) and found that older adults were more likely to exp...

    2003-01-01

    By generalizing the learning rate parameter to a learning rate matrix, this paper proposes agrading learning algorithm for blind source separation. The whole learning process is divided into threestages: initial stage, capturing stage and tracking stage. In different stages, different learning rates areused for each output component, which is determined by its dependency on other output components. Itis shown that the grading learning algorithm is equivariant and can keep the separating matrix from be-coming singular. Simulations show that the proposed algorithm can achieve faster convergence, bettersteady-state performance and higher numerical robustness, as compared with the existing algorithmsusing fixed, time-descending and adaptive learning rates.

  15. Constrained variable projection method for blind deconvolution

    International Nuclear Information System (INIS)

    This paper is focused on the solution of the blind deconvolution problem, here modeled as a separable nonlinear least squares problem. The well known ill-posedness, both on recovering the blurring operator and the true image, makes the problem really difficult to handle. We show that, by imposing appropriate constraints on the variables and with well chosen regularization parameters, it is possible to obtain an objective function that is fairly well behaved. Hence, the resulting nonlinear minimization problem can be effectively solved by classical methods, such as the Gauss-Newton algorithm.

    2015-01-01

    The sky is full of variable and transient sources on all time scales, from milliseconds to decades. Planck's regular scanning strategy makes it an ideal instrument to search for variable sky signals in the millimetre and submillimetre regime, on time scales from hours to several years. A precondition is that instrumental noise and systematic effects, caused in particular by non-symmetric beam shapes, are properly removed. We present a method to perform a full sky blind search for variable and transient objects at all Planck frequencies.

    A 3-year-old boy had persistent cortical blindness following acute carbon monoxide poisoning. He was believed to have suffered anoxic brain damage due to incomplete combustion of the briquette-type solid fuel. Computed tomographic (CT) scan of the brain and visual evoked potentials (VEP) in the early stage were normal. However, on the 20th hospital day CT scan showed leukomalacia and VEP showed an absence of N1-, and P1-waves which was well correlated with the clinical feature at that time. PMID:4083389

    Results of a blind test of photometric redshift predictions against spectroscopic galaxy redshifts obtained in the Hubble Deep Field with the Keck Telescope are presented. The best photometric redshift schemes predict spectroscopic redshifts with a redshift accuracy of |Delta-z|<0.1 for more than 68 percent of sources and with |Delta-z|<0.3 for 100 percent, when single-feature spectroscopic redshifts are removed from consideration. This test shows that photometric redshift schemes work well at least when the photometric data are of high quality and when the sources are at moderate redshifts.
