As a consequence of the research, it has been revealed that the living and non-living things concepts in the mind of the elementary school (4th and 5th classes pupils do not differentiate from each other by gender. Living and non-living concepts are the basic concepts of biology and as a result of this research it is recommended that the elementary pupils be taught living and non-living things without looking gender.

  2. Primary students' conceptions of living things

    Legaspi, Britt Anne

    Elementary school teachers are pressed for time throughout the instructional day to teach all curricular areas as expected by states and districts because of the current focus on reading and mathematics. Thus, foundational science concepts may be overlooked. For example, students' understandings of living and nonliving things may be overlooked by teachers, yet is useful in understanding the nature of living things. In this qualitative study, K-3 grade students were asked to sort objects as either living or nonliving and to give rationales for their choices. It was found that K-3 students readily used physical characteristics, such as having body parts, and physical abilities, such as being able to move, as criteria for living things. Students in grades 1 through 3 were able to articulate their reasons with more adult-like logic based on Jean Piaget' s research on developmental stages.

    This study investigated whether intuitive, naive conceptions of "living things" based on objects' mobility (movement = alive) persist into adolescence and affect 10th graders' accuracy of responses and reaction times during object classification. Most of the 58 students classified the test objects correctly as living/nonliving, yet they demonstrated significantly longer reaction times for classifying plants compared to animals and for classifying dynamic objects compared to static inanimate objects. Findings indicated that, despite prior learning in biology, the intuitive conception of living things persists up to age 15-16 years, affecting related reasoning processes. Consideration of these findings may help educators in their decisions about the nature of examples they use in their classrooms.

    Meaning in life is an important aspect of human well-being and motivation. But as the notion of 'meaning in life' is not easily assimilated to that of semantic meaning, it is difficult to define. While meaning in life is standardly discussed in terms of meaningful ways of living, I here take the alt

  6. When a Bilingual Child Describes Living Things: An Analysis of Conceptual Understandings from a Language Perspective

    2007-07-01

    With increasing numbers of students learning science through a second language in many school contexts, there is a need for research to focus on the impact language has on students’ understanding of science concepts. Like other countries, Brunei has adopted a bilingual system of education that incorporates two languages in imparting its curriculum. For the first three years of school, Brunei children are taught in Malay and then for the remainder of their education, instruction is in English. This research is concerned with the influence that this bilingual education system has on children’s learning of science. The purpose was to document the patterns of Brunei students’ developing understandings of the concepts of living and non-living things and examine the impact in the change in language as the medium of instruction. A cross-sectional case study design was used in one primary school. Data collection included an interview ( n = 75), which consisted of forced-response and semi-structured interview questions, a categorisation task and classroom observation. Data were analysed quantitatively and qualitatively. The results indicate that the transition from Malay to English as the language of instruction from Primary 4 onwards restricted the students’ ability to express their understandings about living things, to discuss related scientific concepts and to interpret and analyse scientific questions. From a social constructivist perspective these language factors will potentially impact on the students’ cognitive development by limiting the expected growth of the students’ understandings of the concepts of living and non-living things.

  7. Visual similarity is greater for line drawings of nonliving than living things: the importance of musical instruments and body parts.

    Laws, Keith R; Gale, Tim M; Frank, Ray; Davey, Neil

    2002-01-01

    It has been argued that greater intra-category structural similarity for living things, and the subsequent "visual crowding," makes them more difficult to recognize and name for neurologically damaged individuals and normal subjects (Humphreys et al., 1988). Nevertheless, the precise meaning and quantification of structural similarity remains unclear, as does the rationale for why it necessarily should be greater for living things. We derived a new measure of visual overlap from the Snodgrass and Vanderwart corpus of line drawings: the degree of pixel overlap within subcategories (Euclidean distance: ED). Contrary to existing notions of visual crowding and extant measures of contour overlap, within-category ED indicated less within-category visual overlap for living things. Furthermore, musical instruments clustered with living things (having low overlap), while body parts clustered with nonliving things (having high overlap). These counter-intuitive findings accord with patient data and thus, provide evidence for the psychological reality and utility of ED.

    Kwon, Young Re

    This qualitative study explored concepts of living things that five- and six-year-old Korean children held prior to formal instructional interventions and how their concepts were changed and developed over one semester in a kindergarten classroom. Six focal children in a class of 30 were interviewed in two phases and their hands-on classroom activities and teacher-children interactions were observed. The teacher's journal was also used to gather data. As the study was conducted, a number of alternative concepts related to the children's perceptions of living things were identified and described. The researcher interviewed the children to determine their initial ideas, using an informal interview guide; they responded whether certain objects were living or not, and how they told if the particular objects were living or not. The classroom activities were also observed in large/small groups and individually. An assisting observer viewed the classroom activities and simultaneously recorded science-related teacher-children interactions and the children's hands-on activities. Later the researcher made a transcription of the observer's notes. The data were also collected from the teacher's journal, in which she recorded everyday classroom activities and reflected on teaching and learning. Finally, after 8 weeks of the 16-week instructional intervention, the researcher interviewed the children, using a formal interview guide, as to how their concepts of living things had changed and developed. The researcher interviewed the children as to whether particular objects were plants or animals, neither or both, and the criteria they used to decide. The study showed that the kindergarten children had solid and unique ideas based on their everyday experience with living and non-living things prior to the formal instructional inventions. In the classroom activities, the children showed that they rejected or changed several of their own concepts of living things. The instructional

    Internet of Things (IoT) is the logical further development of today's Internet, enabling a huge amount of devices to communicate, compute, sense and act. IoT sensors placed in Ambient Assisted Living (AAL) environments, enable the context awareness and allow the support of the elderly in their daily routines, ultimately allowing an independent and safe lifestyle. The vast amount of data that are generated and exchanged between the IoT nodes require innovative context modeling approaches that go beyond currently used models. Current paper presents and evaluates an open interoperable platform architecture in order to utilize the technical characteristics of IoT and handle the large amount of generated data, as a solution to the technical requirements of AAL applications.

    There is a long-standing distinction in Western thought between scientific and historical modes of explanation. According to Aristotle's influential account of scientific knowledge there cannot be an explanatory science of what is contingent and accidental, such things being the purview of a descriptive history. This distinction between scientia and historia continued to inform assumptions about scientific explanation into the nineteenth century and is particularly significant when considering the emergence of biology and its displacement of the more traditional discipline of natural history. One of the consequences of this nineteenth-century transition was that while modern evolutionary theory retained significant, if often implicit, historical components, these were often overlooked as evolutionary biology sought to accommodate itself to a model of scientific explanation that involved appeals to laws of nature. These scientific aspirations of evolutionary biology sometimes sit uncomfortably with its historical dimension. This tension lies beneath recent philosophical critiques of evolutionary theory and its modes of explanation. Such critiques, however, overlook the fact that there are legitimate modes of historical explanation that do not require recourse to laws of nature. But responding to these criticisms calls for a more explicit recognition of the affinities between evolutionary biology and history.

    Full Text Available Problem statement: A study of the pattern of Candida spp. infection of the human body and the mode and pattern of reaction of the human body to this infection showed that disease infectivity and self healing by plants followed the same procedures and patterns. Approach: A comparism of these procedures and patterns of natural self- healing of disease infection by the human body and plants/plant parts with the cutaneous Candida spp. killing and elimination procedures and patterns of Vernonia amygdalina leaf extract, showed that cell surface receptors are the sites through which disease infects the body and also the sites at which the body is defended. They are also the sites where activities which result in normal body functioning are carried out. The mode and patterns of Cutaneous Candida infection in a human subject and its containment by the body was examined and photographed. The disease infection and self healing procedures and patterns of plants were also examined in comparism with those of their healthy counterparts and photographed. The findings from the observations on disease infectivity and natural body’s defence patterns and procedures of the plant parts studied and those of the human body in reaction to Candida spp. infection were compared with those of the Candida spp. killing procedures and patterns of aqueous and Arachis hypogeal oil extract of Vernonia amygdalina leaf. Results: The findings of this study also showed that disease-infective organisms gain access to the body of a host through attachment to the cell surface receptors of that host which are placed linearly and are interconnected by channels. The results of the study also indicated that living organisms have a main endogenous substance that mediates both their body’s defence and their normal physiological functioning which is therefore the owner of the cell surface receptor. Other endogenous substances which participate in normal body functioning/body’s defence or in

A package of cookies on the supermarket shelf suggests that we buy it, based on past purchases. The cookies themselves are on the shelf because of a "smart" supply chain. When we get home, the thermostat has already adjusted the temperature so that it's toasty or bracing, whichever we prefer. This is the Internet of Things -- a networked world of connected devices, objects, and people. In this book, Samuel Greengard offers a guided tour through this emerging world and how it will change the way we live and work.

    Semantic memory was investigated in a patient (MR) affected by a severe apperceptive visual agnosia, due to an ischemic cerebral lesion, bilaterally affecting the infero-mesial parts of the temporo-occipital cortices. The study was made by means of a Semantic Knowledge Questionnaire (Laiacona, Barbarotto, Trivelli, & Capitani, 1993), which takes separately into account four categories of living beings (animals, fruits, vegetables and body parts) and of artefacts (furniture, tools, vehicles and musical instruments), does not require a visual analysis and allows to distinguish errors concerning super-ordinate categorization, perceptual features and functional/encyclopedic knowledge. When the total number of errors obtained on all the categories of living and non-living beings was considered, a non-significant trend toward a higher number of errors in living stimuli was observed. This difference, however, became significant when body parts and musical instruments were excluded from the analysis. Furthermore, the number of errors obtained on the musical instruments was similar to that obtained on the living categories of animals, fruits and vegetables and significantly higher of that obtained in the other artefact categories. This difference was still significant when familiarity, frequency of use and prototypicality of each stimulus entered into a logistic regression analysis. On the other hand, a separate analysis of errors obtained on questions exploring super-ordinate categorization, perceptual features and functional/encyclopedic attributes showed that the differences between living and non-living stimuli and between musical instruments and other artefact categories were mainly due to errors obtained on questions exploring perceptual features. All these data are at variance with the 'domains of knowledge' hypothesis', which assumes that the breakdown of different categories of living and non-living things respects the distinction between biological entities and

    The research presented here aimed to obtain population norms on pertinent domains of quality of life and health related quality of life, and the relative importance of these domains to people. The OPCS Omnibus Survey was used as the vehicle for the study. This is a monthly survey of a random sample of 2000 adult members of the population in Great Britain, based on a random sample of households. The data was collected for a one month period. The response rate to the survey was 77%. In response to a generic question about the five (priority ordered) most important things in their lives (good or bad), respondents were most likely to freely mention as the first most important thing in their lives relationships with family or relatives, followed by their own health, the health of another (close) person and finances/standard of living/housing. When responses relating to respondents' priority ranked areas 1-5 were combined, the most frequently mentioned area of life was finances/standard of living/housing, followed by relationships with family and friends, own health, the health of close others and social life/leisure activities. Thus, different distributions were obtained depending on whether priority ordering or frequency with which item was mentioned was analysed. Of those who reported a longstanding illness, the conditions which were most likely to be reported as affecting their lives were respiratory conditions, joint disorders and heart and circulatory diseases. The most commonly freely mentioned first most important effects of the longstanding illness on their lives were (in order of frequency) ability to get out and about/stand/walk/go out shopping, being able to work/find a job and effects on social life/leisure activities (based on office coding from verbatim responses recorded on the questionnaire). When the responses relating to respondents' priority ranks 1-5 were combined, the most frequently mentioned area of life affected was ability to get out and about

    Evolution is one of the major omnipresent powers in the universe that has been studied for about two centuries. Recent scientific and technical developments make it possible to make the transition from passively understanding to actively mastering evolution. As of today, the only area where human experimenters can design and manipulate evolutionary processes in full is that of Evolutionary Computing, where evolutionary processes are carried out in a digital space, inside computers, in simulation. We argue that in the near future it will be possible to move evolutionary computing outside such imaginary spaces and make it physically embodied. In other words, we envision the "Evolution of Things", rather than just the evolution of code, leading to a new field of Embodied Artificial Evolution (EAE). The main objective of the present paper is to offer an umbrella term and vision in order to aid the development of this high potential research area. To this end, we introduce the notion of EAE, discuss a few examples...

    Full Text Available The purpose of this paper is to yield insight into the nature of relations between things within the Internet of things (IoT paradigm and to build the principles that can potentially be used for progressing from IoT into communities of things (CoT. This study engages in rhetorical analysis—a qualitative research technique designed to yield non-quantitative data and to build a strong theoretical foundation for future studies in the field of IoT. It reveals that things can be perceived as beings within the communication networks; IoT can be organized into CoT; and various models of communities can be generated depending on desired outcomes. The findings require empirical implementation of the proposed principles for creating CoT. The direction indicated in this study will help solve a number of technical challenges that IoT faces nowadays, from architecture and communication to privacy and security. Viewing things as beings will encourage a wide-ranging discussion of the applications of social science theories to IoT. This study is a call for building bridges between the social sciences and information technology.

    Advances in information and communications technologies (ICT) enable new personalized health care concepts which are often characterized by four "P" terms, i.e. personalized, predictive, preventive and participatory. However, real world implementations of the complete 4P spectrum hardly exist today. The Internet of Things (IoT) has been defined as an extension to the current Internet that enables pervasive communication between the physical and the virtual world. Smart devices and enabling elements like Near Field Communication (NFC) and Radio Frequency Identification (RFID) technology already exist and increasingly will be a mainstream element of our lives. This future vision paper attempts to assess if and how the Internet of Things for personalized health (IoT4pH) can help to facilitate the 4P healthcare paradigm and discusses related challenges and opportunities.

    Even the smartest among us can feel inept as we fail to figure out which light switch or oven burner to turn on, or whether to push, pull, or slide a door. The fault, argues this ingenious—even liberating—book, lies not in ourselves, but in product design that ignores the needs of users and the principles of cognitive psychology. The problems range from ambiguous and hidden controls to arbitrary relationships between controls and functions, coupled with a lack of feedback or other assistance and unreasonable demands on memorization. The Design of Everyday Things shows that good, usable design is possible. The rules are simple: make things visible, exploit natural relationships that couple function and control, and make intelligent use of constraints. The goal: guide the user effortlessly to the right action on the right control at the right time. In this entertaining and insightful analysis, cognitive scientist Don Norman hails excellence of design as the most important key to regaining the competitive e...

  7. Interaction, Change, and Wholeness of Material Things

    CERN Document Server

    Semyonov, Oleg G

    2007-01-01

    Interaction is the mode of being of material things amid other material things an the driving force of change and wholeness. Through mutual influence, changes of interacting things become interdependent and their properties interrelated, which leads to formation of ensembles - material wholes of correlated things, where the mode of being of a particular component depends on the modes of being of all other components and vice versa. Every ensemble attains its wholeness and becomes a physical body through togetherness of interrelated components coexisting as a collective being with mutually restrained internal motion. Properties of ensembles on all structural levels of matter composition emerge through the collective being of components.

    Linden, Anni; Wilmanns, Matthias

    2004-02-06

    There are currently 35 available nonredundant molecular structures of class-13 alpha-amylases (EC 3.2.1.1), mostly from microbial organisms living under a wide range of environmental conditions. One of the most recent additions has been the first alpha-amylase structure of a hyperthermophilic archaeon [Linden et al., J. Biol. Chem. 2003, 278, 9875-9884]. The structure has been used for comparative analyses with a representative set of three alpha-amylases from thermophilic, mesophilic and psychrophilic sources to identify molecular parameters for environmental adaptation. Our analysis supports generally observed trends such as an increase in structural compactness as well as an increase in salt bridges in order to cope with high-temperature conditions. The two representative thermophilic structures used in this comparative study have independently evolved di-metal centres--not present in the mesophilic and psychrophilic structures--in the vicinity of the active site. These observations may provide impetus for the design of alpha-amylases with improved molecular properties to enhance their utility in biotechnological processes.

  2. Formations of Feeling, Constellation of Things

    Directory of Open Access Journals (Sweden)

    Ben Highmore

    2016-03-01

    Full Text Available This essay revisits Raymond Williams’s notion of ‘structures of feeling’ with the intention of clarifying what Williams meant by ‘feelings’, and of exploring the concept’s possible range and reach within the study of culture. It recovers the initial anthropological context for the phrase by reconnecting it to the work of Ruth Benedict and Gregory Bateson. It goes on to suggest that while the analysis of ‘structures of feeling’ has been deployed primarily in studies of literary and filmic culture it might be usefully extended towards the study of more ubiquitous forms of material culture such as clothing, housing, food, furnishings and other material practices of daily living. Indeed it might be one way of explaining how formations of feeling are disseminated, how they suture us to the social world and how feelings are embedded in the accoutrements of domestic, habitual life. The essay argues that by joining together a socially phenomenological interest in the world of things, accompanied by an attention to historically specific moods and atmospheres, ‘structures of feelings’ can direct analyses towards important mundane cultural phenomena.

    Full Text Available

     

    Abstract: The act and practise of relating is a key element in developing narratives. This essay will explore the interplay and connections between relating and narrating, and the possibilities of producing alternative narratives, independent from hierarchical structures located in linearity, causality and genealogy, by exploring what Gilles Deleuze termed ‘involution,’ as an alternative device of relating. This essay will explore and exemplify this, by focusing on artistic and curatorial strategies of the artist/curators Carson & Miller in the exhibition The Story of Things. This exhibition’s re-organisation of anthropological and ethnographic objects challenges the conventional and traditional representation of such objects in linear and genealogical ways. Curatorial and artistic strategies of display, such as unconventional juxtapositions, slight shifts of the constituent parts of objects, and incongruous combinations of them will be examined. The essay will argue that such strategies are effective in establishing new modes of narrative organisation and new products of combination and juxtaposition.

  8. A MIDDLEWARE FOR THE INTERNET OF THINGS

    Directory of Open Access Journals (Sweden)

    Mahmoud Elkhodr

    2016-03-01

    Full Text Available The Internet of Things (IoT connects everyday objects including a vast array of sensors, actuators, and smart devices, referred to as “things” to the Internet, in an intelligent and pervasive fashion. This connectivity gives rise to the possibility of using the tracking capabilities of things to impinge on the location privacy of users. Most of the existing management and location privacy protection solutions do not consider the low-cost and low-power requirements of things; or, they do not account for the heterogeneity, scalability, or autonomy of communications supported in the IoT. Moreover, these traditional solutions do not consider the case where a user wishes to control the granularity of the disclosed information based on the context of their use (e.g. based on the time or the current location of the user. To fill this gap, a middleware, referred to as the Internet of Things Management Platform (IoT-MP is proposed in this paper.

    2010-06-01

    Full Text Available This bibliographic essay is based on the book that resulted from a series of discussions promoted by a group of doctoral students in the Department of Social Anthropology at Cambridge University in late 1990s. Despite the diversity of ethnographic contexts, all authors share the challenge of recasting the relationship between anthropological theory and ethnographic method in relation to the study of what is conventionally called material culture. Hence the title Thinking Through Things, besides denoting an anthropological question about what informants do, and how the authors could develop versions on the ways from which they perceive and conceive of things also includes the main character of the meetings that led to the writing of this book.

  17. Breakthrough Towards the Internet of Things

    Chaves, Leonardo W. F.; Nochta, Zoltán

    In this chapter we introduce the Internet of Things (IoT) from the perspective of companies. The Internet of Things mainly refers to the continuous tracking and observation of real-world objects over the Internet. The resulting information can be used to optimize many processes along the entire value chain. Important prerequisites for the IoT are that the objects of interest can be uniquely identified and that their environment can be monitored with sensors. Currently, technologies, such as different types of barcodes, active and passive Radio Frequency Identification (RFID) and wireless sensor networks play the most important role. However, these technologies either do not provide monitoring of their environment or they are too expensive for widespread adoption. Organic Electronics is a new technology that allows printing electronic circuits using organic inks. It will produce ultra-low cost smart labels equipped with sensors, and thus it will become an enabler of the IoT. We discuss how organic smart labels can be used to implement the Internet of Things. We show how this technology is expected to develop. Finally, we indicate technical problems that arise when processing large volumes of data that will result from the usage of organic smart labels in business applications.

    On a traditional view, words are the fundamental units of verbal behavior. They are independent, autonomous things that symbolically represent or refer to other independent, autonomous things, often in some other dimension. Ascertaining what those other things are constitutes determining the meaning of a word. On a behavior-analytic view, verbal behavior is ongoing, functional operant activity occasioned by antecedent factors and reinforced by its consequences, particularly consequences that are mediated by other members of the same verbal community. Functional relations rather than structure select the response unit. The behavior-analytic point of view clarifies such important contemporary issues in psychology as (a) the role of scientific theories and explanations, (b) educational practices, and (c) equivalence classes, so that there is no risk of strengthening the traditional view that words are things that symbolically represent other things.

    Even though public awareness about privacy risks in the Internet is increasing, in the evolution of the Internet to the Internet of Things (IoT) these risks are likely to become more relevant due to the large amount of data collected and processed by the "Things". The business drivers for exploring ways to monetize such data are one of the challenges identified in this paper for the protection of Privacy in the IoT. Beyond the protection of privacy, this paper highlights the need for new approaches, which grant a more active role to the users of the IoT and which address other potential issues such as the Digital Divide or safety risks. A key facet in ethical design is the transparency of the technology and services in how that technology handles data, as well as providing choice for the user. This paper presents a new approach for users' interaction with the IoT, which is based on the concept of Ethical Design implemented through a policy-based framework. In the proposed framework, users are provided with wider controls over personal data or the IoT services by selecting specific sets of policies, which can be tailored according to users' capabilities and to the contexts where they operate. The potential deployment of the framework in a typical IoT context is described with the identification of the main stakeholders and the processes that should be put in place.

    Abstract Background The negative effects of stigma on persons living with HIV (PLHIV) have been documented in many settings and it is thought that stigma against PLHIV leads to more difficulties for those who need to access HIV testing, treatment and care, as well as to limited community uptake of HIV prevention and testing messages. In order to understand and prevent stigma towards PLHIV, it is important to be able to measure stigma within communities and to understand which factors are associated with higher stigma. Methods To analyze patterns of community stigma and determinants to stigma toward PLHIV, we performed an exploratory population-based survey with 1874 randomly sampled adults within a demographic surveillance site (DSS) in rural Vietnam. Participants were interviewed regarding knowledge of HIV and attitudes towards persons living with HIV. Data were linked to socioeconomic and migration data from the DSS and latent class analysis and multinomial logistic regression were conducted to examine stigma group sub-types and factors associated with stigma group membership. Results We found unexpectedly high and complex patterns of stigma against PLHIV in this rural setting. Women had the greatest odds of belong to the highest stigma group (OR 1.84, 95% CI 1.42-2.37), while those with more education had lower odds of highest stigma group membership (OR 0.45, 95% CI 0.32-0.62 for secondary education; OR 0.19, 95% CI 0.10-0.35 for tertiary education). Long-term migration out of the district (OR 0.61, 95% CI 0.4-0.91), feeling at-risk for HIV (OR 0.42, 95% CI 0.27-0.66), having heard of HIV from more sources (OR 0.44, 95% CI 0.3-0.66), and knowing someone with HIV (OR 0.76, 95% CI 0.58-0.99) were all associated with lower odds of highest stigma group membership. Nearly 20% of the population was highly unsure of their attitudes towards PLHIV and persons in this group had significantly lower odds of feeling at-risk for HIV (OR 0.54, 95% CI 0.33-0.90) or of knowing

    Full Text Available We are entering a new era of computing technology, the era of Internet of Things (IoT. An important element for this popularization is the large use of off-the-shelf sensors. Most of those sensors will be deployed by different owners, generally common users, creating what we call the Collaborative IoT. This collaborative IoT helps to increase considerably the amount and availability of collected data for different purposes, creating new interesting opportunities, but also several challenges. For example, it is very challenging to search for and select a desired sensor or a group of sensors when there is no description about the provided sensed data or when it is imprecise. Given that, in this work we characterize the properties of the sensed data in the Internet of Things, mainly the sensed data contributed by several sources, including sensors from common users. We conclude that, in order to safely use data available in the IoT, we need a filtering process to increase the data reliability. In this direction, we propose a new simple and powerful approach that helps to select reliable sensors. We tested our method for different types of sensed data, and the results reveal the effectiveness in the correct selection of sensor data.

    2016-02-01

    Full Text Available This paper aims to address key concept of context awareness in the Internet of Things (IoT domain by providing a model that proactively monitors behaviour of devices and services. This concept represents context into two types of information representation, namely set based and mark-up based ontology for the purpose of defining a context awareness model that accurately represent context in IoT. The context model is defined using Resources, Actors, Ambients and Policies. The model adds value to the next stage of IoT evolution by using context ambients to bring about predictive and proactive modelling in understanding context and context awareness. IoT context is represented using the hierarchical hybrid context model. This model provides a method of representing contexts based on context quality and availability in an entity relation hierarchy form. The model is exemplified using the context management application based on agents. Experimental results indicate that context awareness in the Internet of Things can be enhanced by the proposed model.

    Full Text Available Patients with acquired brain injury may have difficulties in processing a unique semantic category. In patients with the most common semantic deficits, living things is the most commonly compromised domain. Nevertheless, the results of assessing healthy participants are contradictory. Most studies with healthy participants reported better performance with the category of living things, whereas other studies have reported better performance with artifacts, depending on the type of material used. Although researchers generally use black-and-white pictures to assess semantic categories, this kind of material omits an essential perceptual attribute in processing living things: colour. This study assessed a group of young healthy participants to determine differences in naming living things and artifacts in a naming task using black-and-white pictures. The stimuli used were matched according to the major lexical-semantic variables: name agreement, visual complexity, lexical frequency, conceptual familiarity, age of acquisition, number of syllables, and number of phonemes. The results show that healthy participants are more accurate and faster at naming when categorizing artifacts and that artifacts have an advantage over the category living things in which colour is a key attribute (animals and fruits/vegetables. This advantage is lost in relation to the category body parts in which colour is not an essential attribute for their recognition.

    Full Text Available Background: The gradual increase in the number of learners admitted into a nursing college in Gauteng resulted in an increase in class size without a proportional increase in the number of nurse educators.Objectives: To explore and describe the experiences of nurse educators teaching in large classes at a nursing college in Gauteng in order to present recommendations to facilitate teaching and learning.Method: A qualitative, exploratory, descriptive, and phenomenological research design which is contextual in nature was used. A total of 20 nurse educators were selected through purposive sampling, and in-depth phenomenological semi-structured individual interviews were conducted between January and February 2013. Data were analysed together with the field notes, using Tesch’s open coding protocol of qualitative data analysis. Lincoln and Guba’s four principles were used to ensure trustworthiness.Results: The themes that emerged from this study were that nurse educators experienced difficulty in recognising learners as individuals in a large class, using innovative pedagogical strategies, and managing a large class. These findings had a negative impact on meaningful teaching and learning as they interfered with an enabling learning environment.Recommendations: Nurse educators should be empowered with facilitative skills in order to effectively manage a large class and hence to achieve teaching and learning abilities.Conclusion: There is a need for nurse educators to finding alternative ways to overcome challenges associated with teaching in large classes and prepare learners to render individualised, caring and holistic nursing care to each unique patient in the healthcare setting.Keywords: Large class, Teaching, Learning; Hindrance

    Full Text Available The purpose of this study is to treat aspects that are related to the sensitivity of data, information and knowledge transmitted through Internet of Things, helping all people interested in these new ICT technologies to become aware of some ethical issues. In this new media, which is no more in its infancy, the vulnerabilities and attacks are various, caused by technological advances and proliferated through lack of users’ awareness. This warning message is needed because of data, information and knowledge transfer from virtual to physical devices that are connected to wireless networks of different sizes and importance. The transfer is augmented by the extended use of new technologies as RFID, NFC, sensors, 3G and 4G and brings along the adjustment of the traditional information security threats to this new environment, as well as the emergence of new characteristic dangers. The problems treated here are of interest both for each of us, as individuals, and for the organizations managers – especially in a world in which the borderline between the physical and virtual life is becoming more and more difficult to draw.

    Full Text Available The field of usability, user experience (UX design and human-computer interaction (HCI arose in the realm of desktop computers and applications. The current experience in computing has radically evolved into ubiquitous computing over the preceding years. Interactions these days take place on different devices: mobile phones, e-readers and smart TVs, amid numerous smart devices. The use of one service across multiple devices is, at present, common with different form factors. Academic researchers are still trying to figure out the best design techniques for new devices and experiences. The Internet of Things (IoT is growing, with an ever wider range of daily objects acquiring connectivity, sensing ability and increased computing power. Designing for IoT raises a lot of challenges; the obvious difference being the much wider variety of device form factors. IoT is still a technically driven field, thus the usability of many of IoT products is, in some way, of the level anticipated of mature consumer products. This study focuses on proposing a usability evaluation criterion for the generic IoT architecture and essential technological components

    Full Text Available Abstract Internet of things is emerging to be a promising trend towards an era of connectivity. IoT is powered by the internet boom and all the different devices connected to it that share data and communicate with each other. The applications of IoT range from smart clothes to smart cities to healthcare and security and so on. This paper deals with the scope of gaming as an application of IoT. Gamers today demand complete freedom in gaming experience and are always asking for more. To provide this the technology must be invisible yet omnipresent-thats the essence of IoT. Alternate reality gaming is the genre of gaming that has close resemblance to the essence of IoT. ARGs are driven by storyline and typically supported through some type of online game portal that manages the game. Websites social media tools media broadcasts phone calls text messages and sometimes person-to-person interactions are all potential elements that move the storyline along. In ARGs a story drives the game play and players are performing activities that mirror their real life. It also explores the scope of IoT games beyond just gaming and into the business world.

    Full Text Available Purpose – it is becoming increasingly difficult to ignore the input Internet of Things (IoT has to offer in development of public, business and other societal structures. Therefore, paper seeks to determine the current state of knowledge in the field of IoT terms of wisdom creation and emergence of collective intelligence. First, we discuss concept of collective intelligence, then we define phenomena of IoT and identify areas of its application. Later, the author reviews how intelligent outputs of IoT are defined in scientific literature. These findings of theoretical investigation may shed some light on research field that is promising but still very vague.Design/methodology/approach – this article provides a general overview of IoT concept and its growing relation to collective intelligence. Methods of document analysis and content analysis were applied. Theoretical analysis enabled recognition of IoT phenomena in relation to wisdom creation and emergence of collective intelligence.Findings – general overview of the field revealed that new understanding of collective intelligence surfaces. Often intelligent behavior and decisions emerge from ever increasing cooperation between ‘things’ and humans. The variety of new concepts and authors trying to describe relationship of ‘things’ with each other and humans when creating intelligent outcomes revealed that this field is still in its very infancy and still needs considerable amount of industry and scientific efforts to be understood and executed.Research limitations – although the paper has successfully demonstrated that IoT provides vast amounts of data for people to process and create knowledge this could be considered only as initial phase in studying the field. IoT and its intelligent outcomes need more investigations in terms of real life case studies and industry reviews in order to create valid definitions, models and future guidelines. Practical implications – this

    Full Text Available The Internet of Things is predicted to consist of over 50 billion devices aiming to solve problems in most areas of our digital society. A large part of the data communicated is expected to consist of various multimedia contents, such as live audio and video. This article presents a solution for the communication of high definition video in low-delay scenarios (<200 ms under the constraints of devices with limited hardware resources, such as the Raspberry Pi. We verify that it is possible to enable low delay video streaming between Raspberry Pi devices using a distributed Internet of Things system called the SensibleThings platform. Specifically, our implementation transfers a 6 Mbps H.264 video stream of 1280 × 720 pixels at 25 frames per second between devices with a total delay of 181 ms on the public Internet, of which the overhead of the distributed Internet of Things communication platform only accounts for 18 ms of this delay. We have found that the most significant bottleneck of video transfer on limited Internet of Things devices is the video coding and not the distributed communication platform, since the video coding accounts for 90% of the total delay.

Section provides the term definition and history of the Internet of Things. The IEEE 1888 IoT-related standard developed in 2011 as integrated solution based on energy-saving technologies for the Internet of Things. The author considers security challenges for the “smart home” system. Next section reviews the experiments of the author involved in testing of the Internet of Things devices. Materials and Methods: The subjects of study are the Apple Pay, the ZigBee wireless standard, Tesla Model S electric cars. The main methods for identification of security threats are analysis and comparison. Results: The companies of electronic devices simplify and reduce the price of manufacturing process. The customers and users are rarely interested in levels of electronic devices security policies. This is the weakest link of electronic products in terms of security and safety. The tests demonstrated that modern electronic-based technologies do not reach the 100-percentage security level. Apple Pay mobile payment system demonstrated the highest security rating. Discussion and Conclusions: Modern electronic devices for Internet of Things does not meet all safety requirements, from the point of view of the author. The article recommends analyzing the potential threats and developing new security standards. In addition, the logistics of electronic devices for Internet of Things need to be under control from the manufacturer to equipment installation time.

  5. Affine Geometry, Visual Sensation, and Preference for Symmetry of Things in a Thing

    2016-11-01

    Full Text Available Evolution and geometry generate complexity in similar ways. Evolution drives natural selection while geometry may capture the logic of this selection and express it visually, in terms of specific generic properties representing some kind of advantage. Geometry is ideally suited for expressing the logic of evolutionary selection for symmetry, which is found in the shape curves of vein systems and other natural objects such as leaves, cell membranes, or tunnel systems built by ants. The topology and geometry of symmetry is controlled by numerical parameters, which act in analogy with a biological organism’s DNA. The introductory part of this paper reviews findings from experiments illustrating the critical role of two-dimensional (2D design parameters, affine geometry and shape symmetry for visual or tactile shape sensation and perception-based decision making in populations of experts and non-experts. It will be shown that 2D fractal symmetry, referred to herein as the “symmetry of things in a thing”, results from principles very similar to those of affine projection. Results from experiments on aesthetic and visual preference judgments in response to 2D fractal trees with varying degrees of asymmetry are presented. In a first experiment (psychophysical scaling procedure, non-expert observers had to rate (on a scale from 0 to 10 the perceived beauty of a random series of 2D fractal trees with varying degrees of fractal symmetry. In a second experiment (two-alternative forced choice procedure, they had to express their preference for one of two shapes from the series. The shape pairs were presented successively in random order. Results show that the smallest possible fractal deviation from “symmetry of things in a thing” significantly reduces the perceived attractiveness of such shapes. The potential of future studies where different levels of complexity of fractal patterns are weighed against different degrees of symmetry is pointed out

    Binding assays with fluorescently labeled ligands and recombinant receptor proteins are commonly performed in 2D arrays. But many cell surface receptors only function in their native membrane environment and/or in a specific conformation, such as they appear on the surface of live cells. Thus, receptors on live cells should be used for ligand binding assays. Here, it is shown that antibodies preprinted on a glass surface can be used to specifically array a peptide receptor of the immune system, i.e., the major histocompatibility complex class I molecule H-2K(b) , into a defined pattern on the surface of live cells. Monoclonal antibodies make it feasible to capture a distinct subpopulation of H-2K(b) and hold it at the cell surface. This patterned receptor enables a novel peptide-binding assay, in which the specific binding of a fluorescently labeled index peptide is visualized by microscopy. Measurements of ligand binding to captured cell surface receptors in defined confirmations apply to many problems in cell biology and thus represent a promising tool in the field of biosensors.

    Mendel's name more than of any other draws our attention to the personal side in terms of success and failure in science. Mendel lived 19 years after presenting his research findings and died without receiving any recognition for his work. Are premature discoveries things of the past, you may ask? I review the material basis of science in terms of science boundary and field accessibility and analyze the possibility of premature discoveries in different fields of science such as, for example, physics and biology. I conclude that science has reached a stage where progress is being made mostly by pushing the boundary of the known from inside than by leaping across boundaries. As more researchers become engaged in science, and as more publications become open access, on-line, and interactive, the probability of an important discovery remaining buried and going unrecognized would become exceedingly small. Of course, as examples from physics show, a new theory or an important idea can always lie low, unrecognized until it becomes re-discovered and popularized by other researchers. Thus, premature discoveries will become less likely but not forbidden.

    Chinyang Henry Tseng

    2016-01-01

    Full Text Available In the next-generation technology, Internet of Things (IoT, billions of smart objects will communicate with one another to make human lives more convenient. IoT is based on wireless sensor network (WSN, and Zigbee is one of the most popular WSN protocols. A mature IoT environment involves heavy WSN data transmission causing bottleneck problems. However, Zigbee’s AODV routing stack does not have load balance mechanism to handle bursty traffic. Therefore, we develop Multipath Load Balancing (MLB Routing to substitute Zigbee’s AODV routing. Our proposed MLB consists of two main designs: LAYER_DESIGN and LOAD_BALANCE. LAYER_DESIGN assigns nodes into different layers based on node distance to IoT gateway. Nodes can have multiple next-hops delivering IoT data. All neighboring layer nodes exchange flow information containing current load, used by LOAD_BALANCE to estimate future load of next-hops. With MLB, nodes can choose the neighbors with the least load as the next-hops and thus can achieve load balance and avoid bottlenecks. Compared with Zigbee’s AODV and multipath version AODV (AOMDV, experiment results demonstrate that MLB achieves better load balance, lower packet loss rate, and better routing connectivity ratio in both grid and random uniform topologies. MLB provides a more convincing routing solution for IoT applications.

  18. Representing and Reasoning with the Internet of Things: a Modular Rule-Based Model for Ensembles of Context-Aware Smart Things

    Directory of Open Access Journals (Sweden)

    S. W. Loke

    2016-03-01

    Full Text Available Context-aware smart things are capable of computational behaviour based on sensing the physical world, inferring context from the sensed data, and acting on the sensed context. A collection of such things can form what we call a thing-ensemble, when they have the ability to communicate with one another (over a short range network such as Bluetooth, or the Internet, i.e. the Internet of Things (IoT concept, sense each other, and when each of them might play certain roles with respect to each other. Each smart thing in a thing-ensemble might have its own context-aware behaviours which when integrated with other smart things yield behaviours that are not straightforward to reason with. We present Sigma, a language of operators, inspired from modular logic programming, for specifying and reasoning with combined behaviours among smart things in a thing-ensemble. We show numerous examples of the use of Sigma for describing a range of behaviours over a diverse range of thing-ensembles, from sensor networks to smart digital frames, demonstrating the versatility of our approach. We contend that our operator approach abstracts away low-level communication and protocol details, and allows systems of context-aware things to be designed and built in a compositional and incremental manner.

This analysis suggests that the risks are as yet poorly delineated (having features in common with the oracle Pythia, and with Pandora and her box), and that adopting the precautionary principle is appropriate.

    从Internet发展历史及应用环境变化的角度讨论IoT( Internet of Things)提出背景、内涵、组成结构和体系结构等关键问题.在分析对IoT的典型定义的基础上,笔者认为“ITU把IoT作为Internet平台在应用领域实现人、机、和智能化物理对象(SPO)信息全方位互通和实践普适计算理念的下一代Internet及其应用系统的概括”是对IoT更为合理的广义定义.以该定义为基础,全面地分析了“由多个用户域网(CPN)通过骨干通信子网互联”的基本组成结构,讨论了两类SPO-CPN的基本组成结构及其支撑技术;指出SPO的引入主要影响CPN资源网络中的接入部分,属于应用系统的范畴,对Internet基本技术影响甚微.笔者不赞同以欧盟为代表的把IoT定义为联物专用网的狭义定义,指出其IoT模型和体系结构研究混淆了网络平台与应用系统,实质上是网络应用系统模型和体系结构.%Based on the analysis of development history and application environment changes of Internet, this paper provided a comprehensive discussion on the incentive, connotation, organization, and some key issues of the Internet of Things (IoT). On the basis of the analysis of the typical definition of IoT, the author believed that " the full range of information interoperability ITU to IoT as an Internet platform in the application areas of human, machine, and intelligent physical objects (SPO) and the next generation Internet applications generalization of Pervasive Computing (Ubiquitous Computing) concept " is a more reasonable broad definition of the IoT. Based on this definition, the author analyzed the basic organization of IoT, which consisted of interconnected multiple Customer Premises Network (CPN) via backbone Subnetworks, and examined two types of components of SPO-CPN and their supporting techniques. It was also pointed out that introduction of SPO has little impact on Internet technology, except on access part of

    2016-01-01

    This contribution focuses on the medical practice of the policlinics in Würzburg and Göttingen in the first half of the nineteenth century. In these institutions patients were treated free of charge by medical students and assistant physicians who, in turn, were able to gain further experience and develop their skills. The policlinics were therefore an important part of poor-healthcare in both these cities. The essay tries in particular to illustrate healthcare for poor patients against the background of their everyday lives and working environment. Based on the situation of individual poor patients, the concepts of 'sickness' and 'poverty' are discussed as mutually dependent determinants of the 'reality of life' among the urban lower classes. This contribution combines the evaluation of medical practice journals and patient histories with the analysis of source materials on urban poor relief and healthcare. It looks particularly at the children and elderly people who attended the policlinics. The encounters between physicians and poor patients documented in the sources not only provide valuable insights into historical patient behaviours, they also open up new perspectives of the physician-patient relationship during the nineteenth century transition from the 'sickbed-society' to hospital medicine.

Internet of Things is still in full development; this implies that there is a lack of standards for its proper implementation. Among these gaps is for example the technology used to allow objects to connect to the network, since there are several options but none seems to end imposed that is why this work try to provide architecture that imposes an alternative solution to this problem. However, it is difficult to provide a common solution to all the objects used in everyday life because of its great diversity, it requires us to classify them and thus create an appropriate architecture for each of the types These architectures are designed to facilitate the devices orchestration in a similar way as is currently done with web services enabling business process modeling.

    Full Text Available In the future network with Internet of Things (IoT, each of the things communicates with the others and acquires information by itself. In distributed networks for IoT, the energy efficiency of the nodes is a key factor in the network performance. In this paper, we propose energy-efficient probabilistic routing (EEPR algorithm, which controls the transmission of the routing request packets stochastically in order to increase the network lifetime and decrease the packet loss under the flooding algorithm. The proposed EEPR algorithm adopts energy-efficient probabilistic control by simultaneously using the residual energy of each node and ETX metric in the context of the typical AODV protocol. In the simulations, we verify that the proposed algorithm has longer network lifetime and consumes the residual energy of each node more evenly when compared with the typical AODV protocol.

    Tumor cells are inherently heterogeneous and often exhibit diminished adhesion, resulting in the shedding of tumor cells into the circulation to form circulating tumor cells (CTCs). A fraction of these are live CTCs with potential of metastatic colonization whereas others are at various stages of apoptosis making them likely to be less relevant to understanding the disease. Isolation and characterization of live CTCs may augment information yielded by standard enumeration to help physicians to more accurately establish diagnosis, choose therapy, monitor response, and provide prognosis. We previously reported on a group of near-infrared (NIR) heptamethine carbocyanine dyes that are specifically and actively transported into live cancer cells. In this study, this viable tumor cell-specific behavior was utilized to detect live CTCs in prostate cancer patients. Peripheral blood mononuclear cells (PBMCs) from 40 patients with localized prostate cancer together with 5 patients with metastatic disease were stained with IR-783, the prototype heptamethine cyanine dye. Stained cells were subjected to flow cytometric analysis to identify live (NIR(+)) CTCs from the pool of total CTCs, which were identified by EpCAM staining. In patients with localized tumor, live CTC counts corresponded with total CTC numbers. Higher live CTC counts were seen in patients with larger tumors and those with more aggressive pathologic features including positive margins and/or lymph node invasion. Even higher CTC numbers (live and total) were detected in patients with metastatic disease. Live CTC counts declined when patients were receiving effective treatments, and conversely the counts tended to rise at the time of disease progression. Our study demonstrates the feasibility of applying of this staining technique to identify live CTCs, creating an opportunity for further molecular interrogation of a more biologically relevant CTC population.

  10. Anorexia: a taste of things to come?

    Science.gov (United States)

    Wilcock, Andrew

    2006-01-01

    Anorexia, the loss of the desire to eat, is common in patients with cancer. Studies report a prevalence of up to 66% and clinical practice suggests that it is an almost universal experience as the cancer progresses. It generally leads to a reduction in food intake that contributes to the development of malnutrition and cachexia, impairing quality of life and increasing morbidity and mortality. Successful curative or palliative treatment of the underlying cancer is an effective approach. When this is not possible, there are limited treatment options, which generally have not been shown to be practicable, tolerable, effective or safe in the long-term management of the cachexia-anorexia syndrome. Recent increases in the understanding of the physiology of energy intake and of the pathophysiology of anorexia are helping to guide the development of rational approaches. This journal club provides an outline of the pathophysiology of anorexia and highlights a paper that may provide an exciting glimpse of the future.

  11. Unification: Not Just a Thing of Beauty

    Directory of Open Access Journals (Sweden)

    Ioannis Votsis

    2015-03-01

    Full Text Available We often hear that simplicity, explanatory power and unification, though aesthetically pleasing or beautiful qualities, are at best pragmatic considerations in matters of choosing between rival hypotheses. This paper aims to offer a novel conception and an associated measure of unification, both of which are demonstrably more than just pragmatic considerations. The discussion departs from a brief survey of some failed attempts to carve out adequate conceptions of unification. It then proceeds to an analysis of the notions of confirmational connectedness and disconnectedness. Roughly speaking, these notions attempt to capture the way support propagates or fails to propagate between the content parts of a hypothesis or, equivalently, between the contents of two or more hypotheses. The two notions are instrumental in helping to tackle the problem of ad hoc, and in particular monstrous, hypotheses. More importantly for the purposes of this paper, they are essential ingredients in the proposed conception of unification and its associated measure. In simple terms, the more the content of a hypothesis (or, equivalently, the content of a set of hypotheses is confirmationally connected the more that content is unified. Since the confirmational connectedness of two content parts is determined by purely objective matters of fact, the proposed notion and measure of unification are themselves strictly objective, i.e. not merely pragmatic considerations in matters of hypothesis choice. The paper concludes with a discussion of how the proposed measure handles real and hypothetical examples but also how it stands up to various objections.

    Full Text Available This paper develops the notion of heteroclite sociable objects in the context of the emerging internet of things, and examines their transformative effect for understandings of sociability and agency. The notion of sociable objects attempts to capture the heterogeneous identity-shift occurring when heretofore obscure and mute objects ranging from toasters to thermostats acquire the agencies to leave semantically distinct traces online, and detour their human interlocutors into an object-mediated entanglement. Using a toolkit drawn from actor network theory and object oriented ontology, the paper discusses several examples illustrating the case for new parameters of sociability, better suited to a materiality acquiring conversational and anticipatory agencies.

    Full Text Available Although previously accepted as the less toxic alternative, with low impact on animals, farmers as well as consumers who are exposed to residues in food, glyphosate chemicals are now increasingly controversial as new evidence from research is emerging. We argue that specific aspects of the history, chemistry and safety of glyphosate and glyphosate-based herbicides should be thoroughly considered in present and future re-evaluations of these dominant agrochemicals:· Glyphosate is not a single chemical, it is a family of compounds with different chemical, physical and toxicological properties.· Glyphosate is increasingly recognized as having more profound toxicological effects than assumed from previous assessments.· Global use of glyphosate is continuously increasing and residues are detected in food, feed and drinking water. Thus, consumers are increasingly exposed to higher levels of glyphosate residues, and from an increasing number of sources.· Glyphosate regulation is predominantly still based on primary safety-assessment testing in various indicator organisms. However, archive studies indicate fraud and misbehavior committed by the commercial laboratories providing such research.We see emerging evidences from studies in test-animals, ecosystems indicators and studies in human health, which justify stricter regulatory measures. This implies revising glyphosate residue definitions and lowering Maximum Residue Limits (MRLs permissible in biological material intended for food and feed, as well as strengthening environmental criteria such as accepted residue concentrations in surface waters.It seems that although recent research indicates that glyphosates are less harmless than previously assumed and have complex toxicological potential, still regulatory authorities accept industry demands for approving higher levels of these residues in food and feed.

Recent efforts to use persistent identifiers (PIDs), most notably Open Researcher and Contributor ID (ORCiD) for person, Digital Object Identifier (DOI) for publications including data sets, and Open Funder Registry (FundRef) codes for research grants and awards are realizing success in unambiguously identifying the pieces that represent results of environmental research. This presentation uses BCO-DMO as a test case for adding PIDs to the locally-curated information published out as standards compliant metadata records. We present a summary of progress made thus far; what has worked and why, and thoughts on logical next steps.

    The regression of instruction to life raises as a developmental tendency of course reform among the world. Emphasis on the connection between instruction and students’lives has become an important aspect of curriculum reform. The student learner’s role and the development of students’potentials in their lives also have been emphasized;all these conceptions provide broad space for the implementation of life-orientation of instruction. Situational teaching emphasizes that students should be re-garded as the nucleus of the class. Through acquiring knowledge by themselves, they can bear the knowledge in their mind and improve their communicating ability. The teaching activity should always obey the rule of students centered and teacher aided and make sure that the teaching atmosphere can be kept in an authentic situation. And the most important thing that will be talk-ed about is how to apply situational teaching in Junior Middle English Class.

    Full Text Available Visual programming has transformed the art of programming in recent years. Several organizations are in race to develop novel ideas to run visual programming in multiple domains with Internet of Things. IoT, being the most emerging area of computing, needs substantial contribution from the visual programming paradigm for its technological propagation. This paper surveys visual programming languages being served for application development, especially in Internet of Things field. 13 such languages are visited from several popular research-electronic databases (e.g., IEEE Xplore, Science Direct, Springer Link, Google Scholar, Web of Science, and Postscapes and compared under four key attributes such as programming environment, license, project repository, and platform supports. Grouped into two segments, open source and proprietary platform, these visual languages pertain few crucial challenges that have been elaborated in this literature. The main goal of this paper is to present existing VPLs per their parametric proforma to enable naïve developers and researchers in the field of IoT to choose appropriate variant of VPL for particular type of application. It is also worth validating the usability and adaptability of VPLs that is essential for selection of beneficiary in terms of IoT.

    Full Text Available This paper examines the contribution that Warburg's theories can bring to thematology. It does so concretely, above all, through a discussion of historical-literary material. The author hypothesises that the literary representation of non-inert objects took place, in the 18th- and 19th-century fantastic genre, also by using spatio-temporal constants and recurring figurative formulae. By analysing not so much the linguistic, but rather the iconic or imaginative aspect of such constants and formulae (which can be considered as loci communes, these end up resembling Pathosformeln, or moving themes. Through the example of a canonical text such as Berenice, the author illustrates the basic characteristics of this sort of imaginative rhetoric. Subsequently, he shows how the image of things' gaze, which is arguably part of such rhetoric, in the 19th century is transposed also to non-literary texts, and above all to Lacan's psychoanalytic theory. Lastly, on the basis of the arguments and the data collected, the paper proposes an archaeological approach to the study of themes.Keywords: Literary theory, Theme, Thing theory, Fantastic

    Numerous authors have envisioned the future internet where anything will be connected: the Internet of Things (IoT). The idea is an extrapolation of the spread of networked devices such as phones, tablets etc. Each device is expected to have its own Internet address and thus be easy to access. The key building blocks of any IoT system are networking, hardware platforms and node software - so they are similar to wireless sensor network requirements. Most existing IoT demonstrators and applications have been gadget-style objects where power and connectivity problems are not too restricting. Environmental sensor networks can benefit from using some of the technologies involved in IoT development. However it is expected that tuning the networking and power management will be necessary to make them as efficient as state of the art wireless sensor networks. Some IoT assumptions such as always-connected nodes and full IP capability need to be considered. This paper will illustrate the advantages and disadvantages of IoT techniques for environment sensing drawing on a range of employment scenarios. We also describe a glacial 'Internet of things' project, which aims to monitor glacial processes. In particular we describe the IoT developments in a deployment in Iceland to examine glacier seismicity, velocity and provide camera images.

    'In much the same way that HTML and HTTP enabled WWW, the Open Geospatial Consortium (OGC) Sensor Web Enablement (SWE), envisioned in 2001 [1] will allow sensor webs to become a reality.'. Due to the large number of sensor manufacturers and differing accompanying protocols, integrating diverse sensors into observation systems is not a simple task. A coherent infrastructure is needed to treat sensors in an interoperable, platform-independent and uniform way. SWE standardizes web service interfaces, sensor descriptions and data encodings as building blocks for a Sensor Web. SWE standards are now mature specifications (version 2.0) with approved OGC compliance test suites and tens of independent implementations. Many earth and space science organizations and government agencies are using the SWE standards to publish and share their sensors and observations. While SWE has been demonstrated very effective for scientific sensors, its complexity and the computational overhead may not be suitable for resource-constrained tiny sensors. In June 2012, a new OGC Standards Working Group (SWG) was formed called the Sensor Web Interface for Internet of Things (SWE-IoT) SWG. This SWG focuses on developing one or more OGC standards for resource-constrained sensors and actuators (e.g., Internet of Things devices) while leveraging the existing OGC SWE standards. In the near future, billions to trillions of small sensors and actuators will be embedded in real- world objects and connected to the Internet facilitating a concept called the Internet of Things (IoT). By populating our environment with real-world sensor-based devices, the IoT is opening the door to exciting possibilities for a variety of application domains, such as environmental monitoring, transportation and logistics, urban informatics, smart cities, as well as personal and social applications.

    Full Text Available The SELIDA framework is an integration layer of standardized services that takes an Internet-of-Things approach for item traceability in the library setting. The aim of the framework is to provide tracing of RFID tagged physical items among or within various libraries. Using SELIDA we are able to integrate typical library services—such as checking in or out items at different libraries with different Integrated Library Systems—without requiring substantial changes, code-wise, in their structural parts. To do so, we employ the Object Naming Service mechanism that allows us to retrieve and process information from the Electronic Product Code of an item and its associated services through the use of distributed mapping servers. We present two use case scenarios involving the Koha open source ILS and we briefly discuss the potential of this framework in supporting bibliographic Linked Data.

    Internet of Things (IoT) is regarded as a remarkable development of the modern information technology. There is abundant digital products data on the IoT, linking with multiple types of objects/entities. Those associated entities carry rich information and usually in the form of query records. Therefore, constructing high quality topic hierarchies that can capture the term distribution of each product record enables us to better understand users' search intent and benefits tasks such as taxonomy construction, recommendation systems, and other communications solutions for the future IoT. In this paper, we propose a novel record entity topic model (RETM) for IoT environment that is associated with a set of entities and records and a Gibbs sampling-based algorithm is proposed to learn the model. We conduct extensive experiments on real-world datasets and compare our approach with existing methods to demonstrate the advantage of our approach.

The object of my analysis are complex derivatives of the type (adjective noun + suffix in Serbian and componds of the type noun's + noun, noun + noun and adjective + noun in English. I try to show that there is a difference in metaphorical designation of human beings and other living creatures and things by such compound nouns. My thesis is that the metathorical designation of human beings by such compounds is based on the symbolic meaning of some words and expressions while the designation of other things and beings relies on noticed similarity. In Serbian language such designation is provided by comples derivatives praznoglavac 'empty-headed person', tupoglavac 'dullard' debolokoiac 'callos person', golobradac 'young, inexperienced person' žutokljunac 'tledling' (fig, in English chicken liver, beetle brain birdbrain, bonehead, butterfingers, bigwig, blackleg, blue blood bluestocking, eat's paw, deadhead,fat-guts,fathead, goldbrick (kol hardhat, hardhead, greenhorn, redcoat (ist, redneck (sl, thickhead, etc. Polisemous compounds like eat's paw lend support for this thesis because their designation of human beings is based on symbolic meaning of some words or expressions. I hypothesize that the direction and extend of the possible metaphorization of names may be accounted for by the following hierarchy (11 people - animals - plants - meterial things. Such hierarchy is well supported by the observations of Lakoff (1987 and Taylor (1995 about the role of human body in early experience and perception ofthe reality. Different restrictions which may be imposed in the hierarchy (11 should be the matter of further study, some of which have been noted on this paper. The compounds of this type denoting people have

    Full Text Available Smart embedded objects will become an important part of what is called the Internet of Things. However, the integration of embedded devices into the Internet introduces several challenges, since many of the existing Internet technologies and protocols were not designed for this class of devices. In the past few years, there have been many efforts to enable the extension of Internet technologies to constrained devices. Initially, this resulted in proprietary protocols and architectures. Later, the integration of constrained devices into the Internet was embraced by IETF, moving towards standardized IP-based protocols. In this paper, we will briefly review the history of integrating constrained devices into the Internet, followed by an extensive overview of IETF standardization work in the 6LoWPAN, ROLL and CoRE working groups. This is complemented with a broad overview of related research results that illustrate how this work can be extended or used to tackle other problems and with a discussion on open issues and challenges. As such the aim of this paper is twofold: apart from giving readers solid insights in IETF standardization work on the Internet of Things, it also aims to encourage readers to further explore the world of Internet-connected objects, pointing to future research opportunities.

    The Internet of Things (IoT) is a technological revolution that represents the future of computing and communications. One of the most important challenges of IoT is security: protection of data and privacy. The SSL protocol is the de-facto standard for secure Internet communications. The extra energy cost of encrypting and authenticating of the application data with SSL is around 15%. For IoT devices, where energy resources are limited, the increase in the cost of energy is a very significant factor. In this paper we present the energy efficient SSL protocol which ensures the maximum bandwidth and the required level of security with minimum energy consumption. The proper selection of the security level and CPU multiplier, can save up to 85% of the energy required for data encryption.

    The monitoring of runway surfaces, for the detection of ice formation or presence of water, is an important issue for reducing maintenance costs and improving traffic safety. An innovative sensor was developed to detect the presence of ice or water on its surface, and its repeatability, stability and reliability were assessed in different simulations and experiments, performed both in laboratory and in the field. Three sensors were embedded in the runway of the Turin-Caselle airport, in the north-west of Italy, to check the state of its surface. Each sensor was connected to a GPRS modem to send the collected data to a common database. The entire system was installed about three years ago, and up to now it shows correct work and automatic reactivation after malfunctions without any external help. The state of the runway surface is virtual represented in an internet website, using the Internet of Things features and opening new scenarios.

Today’s globalization of food production chains, their extensive complexity and limitations arising from manual insertion and data processing of products information make it impossible for consumers the task of being informed in real-time. This obstacle can be overcome, and the current level of technology and low implementation costs allow full automation of this process. We propose a sensors network architecture based on Internet of Things (IoT components, which is using autonomous embedded modules and radio identification tags (RFID that will automatically collect data, covering the entire life cycle of the food product and all the factors that influence its chemical composition. This architecture offers consumers complete data about their food products and how their components were obtained.

    Abstract— The growth of the Internet of Things (IoT) is driven by market pressures, and while security is being considered, the relationship between the unintended consequences of billions of such devices connecting to the Internet cannot be described with existing mathematical methods. The possibilities for illicit surveillance through lifestyle analysis, unauthorized access to information, and new attack vectors will continue to increase by 2020, when up-to 50 billion devices may be connected. This paper discusses various kinds of vulnerabilities that can be expected to arise, and presents a research agenda for mitigating the worst of the impacts. We hope to draw research attention to the potential dangers of IoT so that many of these problems can be avoided.

    Many localization algorithms and systems have been developed by means of wireless sensor networks for both indoor and outdoor environments. To achieve higher localization accuracy, extra hardware equipments are utilized by most of the existing localization solutions, which increase the cost and considerably limit the location-based applications. The Internet of Things (IOT) integrates many technologies, such as Internet, Zigbee, Bluetooth, infrared, WiFi, GPRS, 3G, etc, which can enable different ways to obtain the location information of various objects. Location-based service is a primary service of the IOT, while localization accuracy is a key issue. In this paper, a higher accuracy localization scheme is proposed which can effectively satisfy diverse requirements for many indoor and outdoor location services. The proposed scheme composes of two phases: 1) partition phase, in which the target region is split into small grids; 2) localization refinement phase, in which a higher accuracy of localization can ...

    When Isaac Newton died in 1727 he left a rich legacy in terms of draft manuscripts, encompassing a variety of topics: natural philosophy, mathematics, alchemy, theology, and chronology, as well as papers relating to his career at the Mint. One thing that immediately strikes us is the textuality of Newton's legacy: images are sparse. Regarding his scholarly endeavours we witness the same practice. Newton's extensive drafts on theology and chronology do not contain a single illustration or map. Today we have all of Newton's draft manuscripts as witnesses of his working methods, as well as access to a significant number of books from his own library. Drawing parallels between Newton's reading practices and his natural philosophical and scholarly work, this paper seeks to understand Newton's recondite writing and publishing politics.

    In recent years, the advancement of sensor technology has led to the generation of heterogeneous Internet-of-Things (IoT) data by smart cities. Thus, the development and deployment of various aspects of IoT-based applications are necessary to mine the potential value of data to the benefit of people and their lives. However, the variety, volume, heterogeneity, and real-time nature of data obtained from smart cities pose considerable challenges. In this paper, we propose a semantic framework that integrates the IoT with machine learning for smart cities. The proposed framework retrieves and models urban data for certain kinds of IoT applications based on semantic and machine-learning technologies. Moreover, we propose two case studies: pollution detection from vehicles and traffic pattern detection. The experimental results show that our system is scalable and capable of accommodating a large number of urban regions with different types of IoT applications.

    The traditional Internet is oriented towards person-to-person connection, whereas the Internet of things (loT) is oriented towards connections between inanimate objects, loT covers a larger range of connections and involves more semantics than traditional Internet. Traditional Internet and telecom networks focus on information transfer, but loT focuses on information services. By combining sensor networks, Internet, telecom networks, and cloud computing platform, loT can sense, recognize, affect, and control the physical world. The physical world can be unified with the virtual world and human perception. In this part, we discuss ubiquitous network convergence and cooperation technologies in terms of their application scenarios, technical advantages and research directions. We also briefly introduce loT services.

    2016-12-02

    This paper addresses the issue of evaluating the Quality of Experience (QoE) for Internet of Things (IoT) applications, with particular attention to the case where multimedia content is involved. A layered IoT architecture is firstly analyzed to understand which QoE influence factors have to be considered in relevant application scenarios. We then introduce the concept of Multimedia IoT (MIoT) and define a layered QoE model aimed at evaluating and combining the contributions of each influence factor to estimate the overall QoE in MIoT applications. Finally, we present a use case related to the remote monitoring of vehicles during driving practices, which is used to validate the proposed layered model, and we discuss a second use case for smart surveillance, to emphasize the generality of the proposed framework. The effectiveness in evaluating classes of influence factors separately is demonstrated.

    Full Text Available Chinua Achebe in his novel Things Fall Apart gives us a unique picture of life in Africa before the arrival of Christianity and colonization and the era afterwards. He shows how African people lost their traditional culture and values, replacing them with foreign beliefs. In this article, the way black people lived before the arrival of white people, how they encountered and reacted to white colonizers, in addition to how they converted to Christianity and subsequently to White culture, as portrayed in this novel, will be analyzed. The purpose of this study is to trace the roots of this rapid pace of colonialism back to when colonial subjects lost their original culture to the new-coming people and to what extent those colonized people were affectively actualizing their inferiority and subordination to the white society. Frantz Fanon’s theories on the relation between language and culture or language and civilization, as well as his discussion of White notion of Blacks and Blacks’ conception of themselves are discussed and analyzed in Achebe’s masterpiece Things Fall Apart to prove that black people attempted to make up for their deep feeling of incompleteness by imitating white people and forming a white personality in a black statue as a result of their own conscious volition.

    2016-07-01

    Full Text Available The new era of computing technology is emerging as it will encompass every aspects of our lives with amazing potentials and it can be termed as Internet of Things (IOT. The IOT generally comprised of smart machines interacting and interactive with other machines, objects, environments and infrastructures. In embedded computing system each thing is uniquely identifiable but it is able to be interoperable within the existing internet infrastructure in IOT. As a result, massive volumes of data are being created, and that data is being processed into useful actions that can “command and control” things to make our living much comfortable and safer—and to ease our impact on the environment. In this paper we have proposed a elephant intrusion monitoring system using IOT. The various drawbacks in already existing system using embedded systems can be overcome as we have cloud based services, low cost and advanced miniaturization in packaging technology. Here we are developing a prototype model for real time interaction of elephant intrusion in forest border areas that allows a persistent monitoring by making use of an On board computer and cloud services.

    2013-01-01

    Full Text Available According to recent research in literary studies, literature has a specific knowledge about things. My contribution supports this thesis by analyzing the world of things in Hans Christian Andersen's fairy tales. Exemplary readings reveal how Andersen's texts acknowledge the power of things in modern life and how these texts thus question scientific and philosophical concepts of subjectivity that dominated in the nineteenth century. The agency of things in Andersen's texts challenges the ideal of a rational subject that acts autonomously. Current theoretical approaches, notably Actor-Network-Theory, allow us to understand the realism of acting things in Andersen's work. That which is marvelous, which is prevalently used to define the genre Fairy Tale in literary studies, is inherent to modernity. The relationship between magic and modernity is different than expected: modernity consists of an interplay between enchantment and disenchantment.

    Internet of Things (IoT) is the next wave of industry revolution that will initiate many services, such as personal health care and green energy monitoring, which people may subscribe for their convenience. Recommending IoT services to the users based on objects they own will become very crucial for the success of IoT. In this work, we introduce the concept of service recommender systems in IoT by a formal model. As a first attempt in this direction, we have proposed a hyper-graph model for IoT recommender system in which each hyper-edge connects users, objects, and services. Next, we studied the usefulness of traditional recommendation schemes and their hybrid approaches on IoT service recommendation (IoTSRS) based on existing well known metrics. The preliminary results show that existing approaches perform reasonably well but further extension is required for IoTSRS. Several challenges were discussed to point out the direction of future development in IoTSR.

    The Internet of Things is built based on various sensors and networks. Sensors for stereo capture are essential for acquiring information and have been applied in different fields. In this paper, we focus on the camera modeling and analysis, which is very important for stereo display and helps with viewing. We model two kinds of cameras, a parallel and a converged one, and analyze the difference between them in vertical and horizontal parallax. Even though different kinds of camera arrays are used in various applications and analyzed in the research work, there are few discussions on the comparison of them. Therefore, we make a detailed analysis about their performance over different shooting distances. From our analysis, we find that the threshold of shooting distance for converged cameras is 7 m. In addition, we design a camera array in our work that can be used as a parallel camera array, as well as a converged camera array and take some images and videos with it to identify the threshold.

    2015-12-01

    Over the next several decades, the population of the world's cities is projected to nearly double, increasing by 2.6 billion people and requiring massive urban expansion globally. This massive growth in urban density and scale will compound ongoing city challenges related to climate change, energy, infrastructure, public health, and more. Cities are using data they already collect such as 311 calls, bus and train operations, street repair orders, census data and building permits to help understand the complex interactions between the human, built and natural systems within a city and inform their decision making. Helping to guide urban decision-making is The Array of Things (AoT): a new tool for measuring many aspects of the physical environment of urban areas at the city block scale with continuous, reliable, integrated data from a variety of sensors. An AoT node includes multiple sensors to measure basic meteorological quantities such as pressure, temperature and humidity as well as light and trace gases such as carbon monoxide, nitrogen dioxide, sulfur dioxide and ozone. The sensors operate 24/7 with ingest frequencies as high as 1Hz. The nodes are modular and allow new sensors to be added or swapped out. The hardware/software backbone of an AoT node is provided by the Waggle architecture. Each AoT node includes, via Waggle, compute power from a single board computer running Linux that allows data to be processed in-situ and, if needed, command and control of components of the node. Data is communicated in near real-time typically through WiFi, 3G or wired ethernet to a designated host and resilience is built-in to prevent data loss if communication is disrupted. The AoT includes a software stack with a programmable API and cloud-based infrastructure for performing data ingest and further analysis. The first full instance of AoT will comprise 500 nodes deployed in the City of Chicago, each with power, Internet, and a base set of sensing and embedded information

  12. Recoverable Random Numbers in an Internet of Things Operating System

    2017-03-01

    Full Text Available Over the past decade, several security issues with Linux Random Number Generator (LRNG on PCs and Androids have emerged. The main problem involves the process of entropy harvesting, particularly at boot time. An entropy source in the input pool of LRNG is not transferred into the non-blocking output pool if the entropy counter of the input pool is less than 192 bits out of 4098 bits. Because the entropy estimation of LRNG is highly conservative, the process may require more than one minute for starting the transfer. Furthermore, the design principle of the estimation algorithm is not only heuristic but also unclear. Recently, Google released an Internet of Things (IoT operating system called Brillo based on the Linux kernel. We analyze the behavior of the random number generator in Brillo, which inherits that of LRNG. In the results, we identify two features that enable recovery of random numbers. With these features, we demonstrate that random numbers of 700 bytes at boot time can be recovered with the success probability of 90% by using time complexity for 5.20 × 2 40 trials. Therefore, the entropy of random numbers of 700 bytes is merely about 43 bits. Since the initial random numbers are supposed to be used for sensitive security parameters, such as stack canary and key derivation, our observation can be applied to practical attacks against cryptosystem.

    2017-01-01

    Full Text Available The Internet of Things (IoT being a promising technology of the future is expected to connect billions of devices. The increased number of communication is expected to generate mountains of data and the security of data can be a threat. The devices in the architecture are essentially smaller in size and low powered. Conventional encryption algorithms are generally computationally expensive due to their complexity and requires many rounds to encrypt, essentially wasting the constrained energy of the gadgets. Less complex algorithm, however, may compromise the desired integrity. In this paper we propose a lightweight encryption algorithm named as Secure IoT (SIT. It is a 64-bit block cipher and requires 64-bit key to encrypt the data. The architecture of the algorithm is a mixture of feistel and a uniform substitution-permutation network. Simulations result shows the algorithm provides substantial security in just five encryption rounds. The hardware implementation of the algorithm is done on a low cost 8-bit micro-controller and the results of code size, memory utilization and encryption/decryption execution cycles are compared with benchmark encryption algo-rithms. The MATLAB code for relevant simulations is available online at https://goo.gl/Uw7E0W.

    Full Text Available The vision for the Internet of Things (IoT demands that material objects acquire communications and computation capabilities and become able to automatically identify themselves through standard protocols and open systems, using the Internet as their foundation. Yet, several challenges still must be addressed for this vision to become a reality. A core ingredient in such development is the ability of heterogeneous devices to communicate adaptively so as to make the best of limited spectrum availability and cope with competition which is inevitable as more and more objects connect to the system. This survey provides an overview of current developments in this area, placing emphasis on wireless sensor networks that can provide IoT capabilities for material objects and techniques that can be used in the context of systems employing low-power versions of the Internet Protocol (IP stack. The survey introduces a conceptual model that facilitates the identification of opportunities for adaptation in each layer of the network stack. After a detailed discussion of specific approaches applicable to particular layers, we consider how sharing information across layers can facilitate further adaptation. We conclude with a discussion of future research directions.

    We present far-infrared spectral line observations of five galaxies from the LITTLE THINGS sample: DDO 69, DDO 70, DDO 75, DDO 155, and WLM. While most studies of dwarfs focus on bright systems or starbursts due to observational constraints, our data extend the observed parameter space into the regime of low surface brightness dwarf galaxies with low metallicities and moderate star formation rates. Our targets were observed with Herschel at the [CII] 158um, [OI] 63um, [OIII] 88um, and NII 122um emission lines using the PACS Spectrometer. These high-resolution maps allow us for the first time to study the far-infrared properties of these systems on the scales of larger star-forming complexes. The spatial resolution in our maps, in combination with star formation tracers, allows us to identify separate PDRs in some of the regions we observed. Our systems have widespread [CII] emission that is bright relative to continuum, averaging near 0.5% of the total infrared budget - higher than in solar-metallicity galaxi...

    Internet Of Things (IOT) drives a significant increase in the extent and type of sensing technology and equipment. Sensors, instrumentation, control electronics, data logging and transmission units comprising such sensing systems will all require to be powered. Conventionally, electrical powering is supplied by batteries or/and electric power cables. The power supply by batteries usually has a limited lifetime, while the electric power cables are susceptible to electromagnetic interference. In fact, the electromagnetic interference is the key issue limiting the power supply in the strong electromagnetic radiation area and other extreme environments. The novel alternative method of power supply is power over fiber (PoF) technique. As fibers are used as power supply lines instead, the delivery of the power is inherently immune to electromagnetic radiation, and avoids cumbersome shielding of power lines. Such a safer power supply mode would be a promising candidate for applications in IOT. In this work, we built up optically powered active sensing system, supplying uninterrupted power for the remote active sensors and communication modules. Also, we proposed a novel maximum power point tracking technique for photovoltaic power convertors. In our system, the actual output efficiency greater than 40% within 1W laser power. After 1km fiber transmission and opto-electric power conversion, a stable electric power of 210mW was obtained, which is sufficient for operating an active sensing system.

    2016-05-01

    In this paper some of the motivations for energy-efficient communications in wireless systems are described by highlighting emerging trends and identifying some challenges that need to be addressed to enable novel, scalable and energy-efficient communications. So an architecture for Internet of Things systems is presented, the purpose of which is to minimize energy consumption by communication devices, protocols, networks, end-user systems and data centers. Some electrical devices have been designed with multiple communication interfaces, such as RF or WiFi, using open source technology; they have been analyzed under different working conditions. Some devices are programmed to communicate directly with a web server, others to communicate only with a special device that acts as a bridge between some devices and the web server. Communication parameters and device status have been changed dynamically according to different scenarios in order to have the most benefits in terms of energy cost and battery lifetime. So the way devices communicate with the web server or between each other and the way they try to obtain the information they need to be always up to date change dynamically in order to guarantee always the lowest energy consumption, a long lasting battery lifetime, the fastest responses and feedbacks and the best quality of service and communication for end users and inner devices of the system.

    Determining the application and version of nodes in the Inter⁃net of Things (IoT) is very important for warning about and managing vulnerabilities in the IoT. This article defines the attributes for determining the application and version of nodes in the IoT. By improving the structure of the Internet web crawler, which obtains raw data from nodes, we can obtain da⁃ta from nodes in the IoT. We improve on the existing strate⁃gy, in which only determinations are stored, by also storing downloaded raw data locally in MongoDB. This stored raw da⁃ta can be conveniently used to determine application type and node version when a new determination method emerges or when there is a new application type or node version. In such instances, the crawler does not have to scan the Internet again. We show through experimentation that our crawler can crawl the IoT and obtain data necessary for determining the application type and node version.

    A decade after our discovery of the involvement of proprotein convertase subtilisin/kexin type 9 (PCSK9) in cholesterol metabolism through the identification of the first mutations leading to hypercholesterolemia, PCSK9 has become one of the most promising targets in cholesterol and cardiovascular diseases. This challenging work in the genetics of hypercholesterolemia paved the way for a plethora of studies around the world allowing the characterization of PCSK9, its expression, its impact on reducing the abundance of LDL receptor, and the identification of loss-of-function mutations in hypocholesterolemia. We highlight the different steps of this adventure and review the published clinical trials especially those with the anti-PCSK9 antibodies evolocumab (AMG 145) and alirocumab (SAR236553/REGN727), which are in phase III trials. The promising results in lowering LDL cholesterol levels raise hope that the PCSK9 adventure will lead, after the large and long-term ongoing phase III studies evaluating efficacy and safety, to a new anticholesterol pharmacological class.

  13. Performance Evaluation of a Dual Coverage System for Internet of Things Environments

    2016-01-01

    Full Text Available A dual coverage system for Internet of Things (IoT environments is introduced. This system is used to connect IoT nodes regardless of their locations. The proposed system has three different architectures, which are based on satellites and High Altitude Platforms (HAPs. In case of Internet coverage problems, the Internet coverage will be replaced with the Satellite/HAP network coverage under specific restrictions such as loss and delay. According to IoT requirements, the proposed architectures should include multiple levels of satellites or HAPs, or a combination of both, to cover the global Internet things. It was shown that the Satellite/HAP/HAP/Things architecture provides the largest coverage area. A network simulation package, NS2, was used to test the performance of the proposed multilevel architectures. The results indicated that the HAP/HAP/Things architecture has the best end-to-end delay, packet loss, throughput, energy consumption, and handover.

    At present, hospitals in our country have basically established the HIS system, which manages registration, treatment, and charge, among many others, of patients. During treatment, patients need to use medical devices repeatedly to acquire all sorts of inspection data. Currently, the output data of the medical devices are often manually input into information system, which is easy to get wrong or easy to cause mismatches between inspection reports and patients. For some small hospitals of which information construction is still relatively weak, the information generated by the devices is still presented in the form of paper reports. When doctors or patients want to have access to the data at a given time again, they can only look at the paper files. Data integration between medical devices has long been a difficult problem for the medical information system, because the data from medical devices are lack of mandatory unified global standards and have outstanding heterogeneity of devices. In order to protect their own interests, manufacturers use special protocols, etc., thus causing medical decices to still be the "lonely island" of hospital information system. Besides, unfocused application of the data will lead to failure to achieve a reasonable distribution of medical resources. With the deepening of IT construction in hospitals, medical information systems will be bound to develop towards mobile applications, intelligent analysis, and interconnection and interworking, on the premise that there is an effective medical device integration (MDI) technology. To this end, this paper presents a MDI model based on the Internet of Things (IoT). Through abstract classification, this model is able to extract the common characteristics of the devices, resolve the heterogeneous differences between them, and employ a unified protocol to integrate data between devices. And by the IoT technology, it realizes interconnection network of devices and conducts associate matching

    We present far-infrared (FIR) spectral line observations of five galaxies from the Little Things sample: DDO 69, DDO 70, DDO 75, DDO 155, and WLM. While most studies of dwarfs focus on bright systems or starbursts due to observational constraints, our data extend the observed parameter space into the regime of low surface brightness dwarf galaxies with low metallicities and moderate star formation rates. Our targets were observed with Herschel at the [C ii] 158 μm, [O i] 63 μm, [O iii] 88 μm, and [N ii] 122 μm emission lines using the PACS Spectrometer. These high-resolution maps allow us for the first time to study the FIR properties of these systems on the scales of larger star-forming complexes. The spatial resolution in our maps, in combination with star formation tracers, allows us to identify separate photodissociation regions (PDRs) in some of the regions we observed. Our systems have widespread [C ii] emission that is bright relative to continuum, averaging near 0.5% of the total infrared (TIR) budget—higher than in solar-metallicity galaxies of other types. [N ii] is weak, suggesting that the [C ii] emission in our galaxies comes mostly from PDRs instead of the diffuse ionized interstellar medium (ISM). These systems exhibit efficient cooling at low dust temperatures, as shown by ([O i]+[C ii])/TIR in relation to 60 μm/100 μm, and low [O i]/[C ii] ratios which indicate that [C ii] is the dominant coolant of the ISM. We observe [O iii]/[C ii] ratios in our galaxies that are lower than those published for other dwarfs, but similar to levels noted in spirals.

  16. Medical Internet of Things and Big Data in Healthcare

    Science.gov (United States)

    2016-01-01

    Objectives A number of technologies can reduce overall costs for the prevention or management of chronic illnesses. These include devices that constantly monitor health indicators, devices that auto-administer therapies, or devices that track real-time health data when a patient self-administers a therapy. Because they have increased access to high-speed Internet and smartphones, many patients have started to use mobile applications (apps) to manage various health needs. These devices and mobile apps are now increasingly used and integrated with telemedicine and telehealth via the medical Internet of Things (mIoT). This paper reviews mIoT and big data in healthcare fields. Methods mIoT is a critical piece of the digital transformation of healthcare, as it allows new business models to emerge and enables changes in work processes, productivity improvements, cost containment and enhanced customer experiences. Results Wearables and mobile apps today support fitness, health education, symptom tracking, and collaborative disease management and care coordination. All those platform analytics can raise the relevancy of data interpretations, reducing the amount of time that end users spend piecing together data outputs. Insights gained from big data analysis will drive the digital disruption of the healthcare world, business processes and real-time decision-making. Conclusions A new category of "personalised preventative health coaches" (Digital Health Advisors) will emerge. These workers will possess the skills and the ability to interpret and understand health and well-being data. They will help their clients avoid chronic and diet-related illness, improve cognitive function, achieve improved mental health and achieve improved lifestyles overall. As the global population ages, such roles will become increasingly important. PMID:27525156

    The Web of Things (WoT) plays an important role in the representation of the objects connected to the Internet of Things in a more transparent and effective way. Thus, it enables seamless and ubiquitous web communication between users and the smart things. Considering the importance of WoT, we propose a WoT-based emerging sensor network (WoT-ESN), which collects data from sensors, routes sensor data to the web, and integrate smart things into the web employing a representational state transfer (REST) architecture. A smart home scenario is introduced to evaluate the proposed WoT-ESN architecture. The smart home scenario is tested through computer simulation of the energy consumption of various household appliances, device discovery, and response time performance. The simulation results show that the proposed scheme significantly optimizes the energy consumption of the household appliances and the response time of the appliances.

    2017-03-14

    The Internet of Things (IoT) offers opportunities for new applications and services that enable users to access and control their working and home environment from local and remote locations, aiming to perform daily life activities in an easy way. However, the IoT also introduces new challenges, some of which arise from the large range of devices currently available and the heterogeneous interfaces provided for their control. The control and management of this variety of devices and interfaces represent a new challenge for non-expert users, instead of making their life easier. Based on this understanding, in this work we present a natural language interface for the IoT, which takes advantage of Semantic Web technologies to allow non-expert users to control their home environment through an instant messaging application in an easy and intuitive way. We conducted several experiments with a group of end users aiming to evaluate the effectiveness of our approach to control home appliances by means of natural language instructions. The evaluation results proved that without the need for technicalities, the user was able to control the home appliances in an efficient way.

    2016-09-01

    Full Text Available In recent years, the advancement of sensor technology has led to the generation of heterogeneous Internet-of-Things (IoT data by smart cities. Thus, the development and deployment of various aspects of IoT-based applications are necessary to mine the potential value of data to the benefit of people and their lives. However, the variety, volume, heterogeneity, and real-time nature of data obtained from smart cities pose considerable challenges. In this paper, we propose a semantic framework that integrates the IoT with machine learning for smart cities. The proposed framework retrieves and models urban data for certain kinds of IoT applications based on semantic and machine-learning technologies. Moreover, we propose two case studies: pollution detection from vehicles and traffic pattern detection. The experimental results show that our system is scalable and capable of accommodating a large number of urban regions with different types of IoT applications.

    2016-06-01

    In recent years, with the increasing world environmental pollution happening, sudden water pollution incident has become more and more frequently in China. It has posed a serious threat to water safety of the people living in the water source area. Conventional water pollution monitoring method is manual periodic testing, it maybe miss the best time to find that pollution incident. This paper proposes a water pollution warning framework to change this state. On the basis of the Internet of things, we uses automatic water quality monitoring technology to realize monitoring. We calculate the monitoring data with water pollution model to judge whether the water pollution incident is happen or not. Water pollution warning framework is divided into three layers: terminal as the sensing layer, it with the deployment of the automatic water quality pollution monitoring sensor. The middle layer is the transfer network layer, data information implementation is based on GPRS wireless network transmission. The upper one is the application layer. With these application systems, early warning information of water pollution will realize the high-speed transmission between grassroots units and superior units. The paper finally gives an example that applying this pollution warning framework to water quality monitoring of Beijing, China, it greatly improves the speed of the pollution warning responding of Beijing.

    Concerns about security on Internet of Things (IoT) cover data privacy and integrity, access control, and availability. IoT abuse in distributed denial of service attacks is a major issue, as typical IoT devices' limited computing, communications, and power resources are prioritized in implementing functionality rather than security features. Incidents involving attacks have been reported, but without clear characterization and evaluation of threats and impacts. The main purpose of this work is to methodically assess the possible impacts of a specific class-amplified reflection distributed denial of service attacks (AR-DDoS)-against IoT. The novel approach used to empirically examine the threat represented by running the attack over a controlled environment, with IoT devices, considered the perspective of an attacker. The methodology used in tests includes that perspective, and actively prospects vulnerabilities in computer systems. This methodology defines standardized procedures for tool-independent vulnerability assessment based on strategy, and the decision flows during execution of penetration tests (pentests). After validation in different scenarios, the methodology was applied in amplified reflection distributed denial of service (AR-DDoS) attack threat assessment. Results show that, according to attack intensity, AR-DDoS saturates reflector infrastructure. Therefore, concerns about AR-DDoS are founded, but expected impact on abused IoT infrastructure and devices will be possibly as hard as on final victims.

    The advent of 3D printing is giving us new production opportunities but is creating new economic and social assets. In the paper we will analyze the new conditions we will live in. The current industrial production scenario will be analyzed to see how it works and how 3D printing is being introduced into it: where the traditional production comes from and how it actually works, from the historical, technological, social and economic point of view, including transports of materials and products. This asset is being "polluted" and possibly transformed by 3D printing: what is it, how it works, but most important, how this technology is transforming our personal approach to industrial products.

    Thanks to the recent advances of miniaturization and the falling costs for sensors and also communication technologies, Internet specially, the number of internet-connected things growth tremendously. Moreover, geosensors with capability of generating high spatial and temporal resolution data, measuring a vast diversity of environmental data and automated operations provide powerful abilities to environmental monitoring tasks. Geosensor nodes are intuitively heterogeneous in terms of the hardware capabilities and communication protocols to take part in the Internet of Things scenarios. Therefore, ensuring interoperability is an important step. With this respect, the focus of this paper is particularly on incorporation of geosensor networks into Internet of things through an architecture for monitoring real-time environmental data with use of OGC Sensor Web Enablement standards. This approach and its applicability is discussed in the context of an air pollution monitoring scenario.

    2016-01-01

    Internet of Things is starting to be implemented in healthcare. An example is the automated monitoring systems that are currently being used to provide healthcare workers with feedback regarding their hand hygiene compliance. These solutions seem effective in promoting healthcare workers self-awareness and action regarding their hand hygiene performance, which is still far from desired. Underlying these systems, an indoor positioning component (following Internet of Things paradigm) is used to collect data from the ward regarding healthcare workers' position, which will be later used to make some assumptions about the usage of alcohol-based handrub dispensers and sinks. We found that building such a system under the scope of the healthcare field is not a trivial task and it must be subject to several considerations, which are presented, analyzed and discussed in this paper. The limitations of present Internet of Things technologies are not yet ready to address the demanding field of healthcare.

    Why was there a meltdown at the Fukushima power plant? Why do some people get cancer and not others? Why is global warming happening? Why does one person get depressed in the face of life's vicissitudes while another finds resilience? Questions like these -- questions of causality -- form the basis of modern scientific inquiry, posing profound intellectual and methodological challenges for researchers in the physical, natural, biomedical, and social sciences. In this groundbreaking book, noted psychiatrist and author Peter Rabins offers a conceptual framework for analyzing daunting questions of causality. Navigating a lively intellectual voyage between the shoals of strict reductionism and relativism, Rabins maps a three-facet model of causality and applies it to a variety of questions in science, medicine, economics, and more. Throughout this book, Rabins situates his argument within relevant scientific contexts, such as quantum mechanics, cybernetics, chaos theory, and epigenetics. A renowned communicator o...

    2016-06-14

    The Internet-of-things (IoT) refers to the massive integration of electronic devices, vehicles, buildings, and other objects to collect and exchange data. It is the enabling technology for a plethora of applications touching various aspects of our lives such as healthcare, wearables, surveillance, home automation, smart manufacturing, and intelligent automotive systems. Existing IoT architectures are highly centralized and heavily rely on a back-end core network for all decision-making processes. This may lead to inefficiencies in terms of latency, network traffic management, computational processing, and power consumption. In this paper, we advocate the empowerment of front-end IoT devices to support the back-end network in fulfilling end-user applications requirements mainly by means of improved connectivity and efficient network management. A novel conceptual framework is presented for a new generation of IoT devices that will enable multiple new features for both the IoT administrators as well as end users. Exploiting the recent emergence of software-defined architecture, these smart IoT devices will allow fast, reliable, and intelligent management of diverse IoT-based applications. After highlighting relevant shortcomings of the existing IoT architectures, we outline some key design perspectives to enable front-end intelligence while shedding light on promising future research directions.

    We present high-resolution rotation curves and mass models of 26 dwarf galaxies from LITTLE THINGS. LITTLE THINGS is a high-resolution Very Large Array HI survey for nearby dwarf galaxies in the local volume within 11 Mpc. The rotation curves of the sample galaxies derived in a homogeneous and consistent manner are combined with Spitzer archival 3.6 micron and ancillary optical U, B, and V images to construct mass models of the galaxies. We decompose the rotation curves in terms of the dynamical contributions by baryons and dark matter halos, and compare the latter with those of dwarf galaxies from THINGS as well as Lambda CDM SPH simulations in which the effect of baryonic feedback processes is included. Being generally consistent with THINGS and simulated dwarf galaxies, most of the LITTLE THINGS sample galaxies show a linear increase of the rotation curve in their inner regions, which gives shallower logarithmic inner slopes alpha of their dark matter density profiles. The mean value of the slopes of the 2...

    2015-12-24

    The Internet of Things (IoT), which can be regarded as an enhanced version of machine-to-machine communication technology, was proposed to realize intelligent thing-to-thing communications by utilizing the Internet connectivity. In the IoT, "things" are generally heterogeneous and resource constrained. In addition, such things are connected to each other over low-power and lossy networks. In this paper, we propose an inter-device authentication and session-key distribution system for devices with only encryption modules. In the proposed system, unlike existing sensor-network environments where the key distribution center distributes the key, each sensor node is involved with the generation of session keys. In addition, in the proposed scheme, the performance is improved so that the authenticated device can calculate the session key in advance. The proposed mutual authentication and session-key distribution system can withstand replay attacks, man-in-the-middle attacks, and wiretapped secret-key attacks.

    Full Text Available The present article is the study of Louise Erdrich’s Tracks (1997 and Arundhati Roy’s The God of Small Things (1988 in the light of postcolonial feminism theories of Spivak. Feminist discourse shares many similarities with post-colonial theory and for this reason the two fields have long been thought of as associative, even complimentary. “Subalternity” is a very important term in both post-colonial and feminist aspects. The word Subaltern describes the lower classes and the social groups who are at the margins of a society. Tracks and The God of Small Things depict the cultural background of their authors. Erdrich Native American culture and Roy's Indian heritage has helped them in creating certain types of female characters in their novels that still carry within themselves some features of their culture. In these novels Louise Erdrich and Roy's main focus is on the female protagonists and the specific roles they have within their communities. Although these novels depict two different cultures, there are many similarities that these two cultures share. Roy and Erdrich present several different female characters in their novels The God of Small Things and Tracks, all in different ways trapped in a system of oppression but also with a substantial degree of agency. From a postcolonial feminist perspective, Roy and Erdrich have contributed to make the representation of the subaltern women more diverse, through giving us various portraits of women that, despite their oppressed and marginalized status.

    The User-Generated Service (UGS) concept allows end-users to create their own services as well as to share and manage the lifecycles of these services. The current development of the Internet-of-Things (IoT) has brought new challenges to the UGS area. Creating smart services in the IoT environment requires a dynamic social network that considers the relationship between people and things. In this paper, we consider the know-how required to best organize exchanges between users and things to enhance service composition. By surveying relevant aspects including service composition technology, social networks and a recommendation system, we present the first concept of our framework to provide recommendations for a dynamic social network-based means to organize UGSs in the IoT.

    2016-01-01

    We explore the question of which shape a manifold is compelled to take when immersed into another one, provided it must be the extremum of some functional. We consider a family of functionals which depend quadratically on the extrinsic curvatures and on projections of the ambient curvatures. These functionals capture a number of physical setups ranging from holography to the study of membranes and elastica. We present a detailed derivation of the equations of motion, known as the shape equations, placing particular emphasis in the issue of gauge freedom in the choice of normal frame. We apply these equations to the specific case of holographic entanglement entropy for higher-curvature three-dimensional gravity and find new classes of entangling curves. In particular, we discuss the case of New Massive Gravity where we show that non-geodesic entangling curves have always a smaller on-shell value of the entropy functional. Nevertheless, the correct value for the entanglement entropy is provided by geodesics. Th...

    2009-02-01

    Full Text Available Abstract Background For older persons with complex care needs, accounting for the variability and interdependency in how health dimensions manifest themselves is necessary to understand the dynamic of health status. Our objective is to test the hypothesis that a latent classification can capture this heterogeneity in a population of frail elderly persons living in the community. Based on a person-centered approach, the classification corresponds to substantively meaningful groups of individuals who present with a comparable constellation of health problems. Methods Using data collected for the SIPA project, a system of integrated care for frail older people (n = 1164, we performed latent class analyses to identify homogenous categories of health status (i.e. health profiles based on 17 indicators of prevalent health problems (chronic conditions; depression; cognition; functional and sensory limitations; instrumental, mobility and personal care disability Then, we conducted latent transition analyses to study change in profile membership over 2 consecutive periods of 12 and 10 months, respectively. We modeled competing risks for mortality and lost to follow-up as absorbing states to avoid attrition biases. Results We identified four health profiles that distinguish the physical and cognitive dimensions of health and capture severity along the disability dimension. The profiles are stable over time and robust to mortality and lost to follow-up attrition. The differentiated and gender-specific patterns of transition probabilities demonstrate the profiles' sensitivity to change in health status and unmasked the differential relationship of physical and cognitive domains with progression in disability. Conclusion Our approach may prove useful at organization and policy levels where many issues call for classification of individuals into pragmatically meaningful groups. In dealing with attrition biases, our analytical strategy could provide critical

It is hard for users including people and smart things to master valuable information hidden in the massive data, which is more useful and understandable than raw data for users to get the crucial points for problems-solving. Thus, how to automatically and actively extract the knowledge of events and their internal links from the big data is one key challenge for the future Web of Things. This paper proposes an effective approach to extract events and their internal links from large scale data leveraging predefined event schemas in the Web of Things, which starts with grasping the critical data for useful events by filtering data with well-defined event types in the schema. A case study in the context of smart campus is presented to show the application of proposed approach for the extraction of events and their internal semantic links.

    Floris, Alessandro; Atzori, Luigi

    2016-01-01

    This paper addresses the issue of evaluating the Quality of Experience (QoE) for Internet of Things (IoT) applications, with particular attention to the case where multimedia content is involved. A layered IoT architecture is firstly analyzed to understand which QoE influence factors have to be considered in relevant application scenarios. We then introduce the concept of Multimedia IoT (MIoT) and define a layered QoE model aimed at evaluating and combining the contributions of each influence factor to estimate the overall QoE in MIoT applications. Finally, we present a use case related to the remote monitoring of vehicles during driving practices, which is used to validate the proposed layered model, and we discuss a second use case for smart surveillance, to emphasize the generality of the proposed framework. The effectiveness in evaluating classes of influence factors separately is demonstrated. PMID:27918437

    Full Text Available The number of devices on the Internet exceeded the number of people on the Internet in 2008, and is estimated to reach 50 billion in 2020. A wide-ranging Internet of Things (IOT ecosystem is emerging to support the process of connecting real-world objects like buildings, roads, household appliances, and human bodies to the Internet via sensors and microprocessor chips that record and transmit data such as sound waves, temperature, movement, and other variables. The explosion in Internet-connected sensors means that new classes of technical capability and application are being created. More granular 24/7 quantified monitoring is leading to a deeper understanding of the internal and external worlds encountered by humans. New data literacy behaviors such as correlation assessment, anomaly detection, and high-frequency data processing are developing as humans adapt to the different kinds of data flows enabled by the IOT. The IOT ecosystem has four critical functional steps: data creation, information generation, meaning-making, and action-taking. This paper provides a comprehensive review of the current and rapidly emerging ecosystem of the Internet of Things (IOT.

    2016-04-01

    Full Text Available The Web of Things aims to make physical world objects and their data accessible through standard Web technologies to enable intelligent applications and sophisticated data analytics. Due to the amount and heterogeneity of the data, it is challenging to perform data analysis directly; especially when the data is captured from a large number of distributed sources. However, the size and scope of the data can be reduced and narrowed down with search techniques, so that only the most relevant and useful data items are selected according to the application requirements. Search is fundamental to the Web of Things while challenging by nature in this context, e.g., mobility of the objects, opportunistic presence and sensing, continuous data streams with changing spatial and temporal properties, efficient indexing for historical and real time data. The research community has developed numerous techniques and methods to tackle these problems as reported by a large body of literature in the last few years. A comprehensive investigation of the current and past studies is necessary to gain a clear view of the research landscape and to identify promising future directions. This survey reviews the state-of-the-art search methods for the Web of Things, which are classified according to three different viewpoints: basic principles, data/knowledge representation, and contents being searched. Experiences and lessons learned from the existing work and some EU research projects related to Web of Things are discussed, and an outlook to the future research is presented.

  1. Environment Observation System based on Semantics in the Internet of Things

    Directory of Open Access Journals (Sweden)

    Liang Hu

    2013-12-01

    Full Text Available The Internet of Things is rapidly developing in recent years. A number of devices connect with the Internet. Hence, the interoperability, which is the access and interpretation of unambiguous data, is strongly needed by distributed and heterogeneous devices. The semantics promotes the interoperability in the Internet of Things using ontology to provide precise definition of concepts and relations. In this paper, we demonstrate the importance of the semantics in three aspects: firstly, the semantics means that the machines could understand and respond to the human command. Secondly, the semantics is mainly reflected in the ontology of the physical world. Thirdly, the semantics is important for interoperability, data integration and reasoning. Then, we introduce a semantic approach to construct an environment observation system in the Internet of Things. The environment observation system contains three major components, the first is the ontology of the environment observation system, the second is the semantic map of the environment observation system, and the last is exposing the observation data. Finally, the system publishes the environment observation data on the Web successfully. The environment observation system with semantics provides a better service in the Internet of Things

    This book sets out the conditions in which the need for a new approach to the production of architecture in the twenty-first century is established, where our homes and cities are facing increasing pressures from environmental challenges that are compromising our well being and our lives. Vibrant architecture embodies a new kind of architectural design practice that explores how lively materials, or ‘vibrant matter’ may be incorporated into our buildings to confer on them some of the properties of living things such as, movement, growth, sensitivity and self-repair. My research examines the theoretical and practical implications of how this may occur through the application of a new group of materials in the production of our living spaces, collectively referred to as ‘vibrant matter’.

  6. Growing in Motion: The Circulation of Used Things on Second-hand Markets

    Directory of Open Access Journals (Sweden)

    2015-03-01

    Full Text Available From having been associated with poverty and low status, the commerce with second-hand goods in retro shops, flea markets, vintage boutiques and trade via Internet is expanding in Sweden as in many countries in the Global North. This article argues that a significant aspect of the recent interest in second-hand and reuse concerns the meaning fulness of circulation in social life. Using classic anthropological theory on how the circulation of material culture generates sociality, it focuses on how second-hand things are transformed by their circulation. Rather than merely having cultural biographies, second-hand things are reconfigured through their shifts between different social contexts in a process that here is understood as a form of growing. Similar to that of an organism, this growth is continuous, irreversible and dependent on forces both internal and external to it. What emerges is a category of things that combine elements of both commodities and gifts, as these have been theorized within anthropology. While first cycle commodities are purified of their sociality, the hybrid second-hand thing derives its ontological status as well as social and commercial value precisely from retaining "gift qualities", produced by its circulation.

  10. Detection and Interpretation of Long-lived X-Ray Quasi-periodic Pulsations in the X-class Solar Flare on 2013 May 14

    Dennis, Brian R.; Tolbert, Anne K.; Inglis, Andrew; Ireland, Jack; Wang, Tongjiang; Holman, Gordon D.; Hayes, Laura A.; Gallagher, Peter T.

    2017-02-01

    Quasi-periodic pulsations (QPP) seen in the time derivative of the GOES soft X-ray light curves are analyzed for the X3.2 event on 2013 May 14. The pulsations are apparent for a total of at least two hours from the impulsive phase to well into the decay phase, with a total of 163 distinct pulses evident to the naked eye. A wavelet analysis shows that the characteristic timescale of these pulsations increases systematically from ∼25 s at 01:10 UT, the time of the GOES peak, to ∼100 s at 02:00 UT. A second “ridge” in the wavelet power spectrum, most likely associated with flaring emission from a different active region, shows an increase from ∼40 s at 01:40 UT to ∼100 s at 03:10 UT. We assume that the QPP that produced the first ridge result from vertical kink-mode oscillations of the newly formed loops following magnetic reconnection in the coronal current sheet. This allows us to estimate the magnetic field strength as a function of altitude given the density, loop length, and QPP timescale as functions of time determined from the GOES light curves and Ramaty High Energy Solar Spectroscopic Imager (RHESSI) images. The calculated magnetic field strength of the newly formed loops ranges from ∼500 G at an altitude of 24 Mm to a low value of ∼10 G at 60 Mm, in general agreement with the expected values at these altitudes. Fast sausage-mode oscillations are also discussed and cannot be ruled out as an alternate mechanism for producing the QPP.

  16. Class III obesity and unwanted pregnancy among women with live births in New York City, 2004-2007.

    Science.gov (United States)

    Garbers, Samantha; Chiasson, Mary Ann

    2013-10-01

    Obesity is associated with numerous adverse health effects for pregnant women and their newborns. Unintended pregnancy is associated with suboptimal prenatal health behaviors and adverse birth outcomes. While research has suggested a link between obesity and unintended pregnancy, the evidence has been contradictory. Research has not focused on women at the highest level of obesity, Class III (body mass index ≥40). Pregnancy Risk Assessment Monitoring System data for 4,161 women in New York City with a live birth from 2004 to 2007 and complete data on pregnancy intention, height, and weight were examined. The primary outcome, having a live birth that resulted from an unwanted pregnancy (not wanted at that time or at any time in the future), was compared across 6 groups of pre-pregnancy body mass index (BMI). Logistic regression models adjusting for sociodemographic factors and stressors during pregnancy were conducted. The proportion of women reporting their pregnancy was unwanted increased with increasing BMI level to a high of 24 % among women with Class III obesity. After adjustment for confounding sociodemographic factors, women classified as Class III obese were significantly more likely than women with normal BMI to report an unwanted pregnancy [AOR = 2.81 (95 % CI: 1.41-5.60)]; this relationship held after adjusting for stressors during pregnancy. No significant association was found for women of other BMI groups. Previous analyses may have masked a relationship between BMI and unwanted pregnancy among women with Class III obesity. Further research exploring underlying mechanisms which are amenable to intervention is of critical public health importance.

  17. Mutual Authentication Scheme in Secure Internet of Things Technology for Comfortable Lifestyle

    Directory of Open Access Journals (Sweden)

    Namje Park

    2015-12-01

    Full Text Available The Internet of Things (IoT, which can be regarded as an enhanced version of machine-to-machine communication technology, was proposed to realize intelligent thing-to-thing communications by utilizing the Internet connectivity. In the IoT, “things” are generally heterogeneous and resource constrained. In addition, such things are connected to each other over low-power and lossy networks. In this paper, we propose an inter-device authentication and session-key distribution system for devices with only encryption modules. In the proposed system, unlike existing sensor-network environments where the key distribution center distributes the key, each sensor node is involved with the generation of session keys. In addition, in the proposed scheme, the performance is improved so that the authenticated device can calculate the session key in advance. The proposed mutual authentication and session-key distribution system can withstand replay attacks, man-in-the-middle attacks, and wiretapped secret-key attacks.

    2016-06-01

    Over 20 years ago, the Australian Liberal/National Party Federal Opposition had a set of policies with which it hoped to persuade the Australian people to return it to government in the election due in 1996. This particular collection of proposed initiatives was called "The things that matter". When the then leader of the opposition, Alexander Downer (later Australia's Foreign Minister 1996-2007 and now Australian High Commissioner in London), launched the Opposition's policy on family violence (the Coalition parties, like their Labor opponents, were and are against it in principle), his introductory line was: "From the things that matter to the things that batter". Not long afterwards he lost his job as Opposition Leader, his engagement with what was and is a serious and troubling issue having been deemed too glib by half by the shapers of public opinion.

    The Internet of things (IOT) is a kind of intelligent networks which can be used to locate, track, identify and supervise people and objects. One of important core technologies of intelligent visual internet of things ( IVIOT) is the intelligent visual tag system. In this paper, a research is done into visual feature extraction and establishment of visual tags of the human face based on ORL face database. Firstly, we use the principal component analysis (PCA) algorithm for face feature extraction, then adopt the support vector machine (SVM) for classifying and face recognition, finally establish a visual tag for face which is already classified.

    Cloud computing and the Internet of Things are the two hot points in the Internet application field. The application of the two new technologies is in hot discussion and research, but quite less on the field of medical monitoring and managing application. Thus, in this paper, we study and analyze the application of cloud computing and the Internet of Things on the medical field. And we manage to make a combination of the two techniques in the medical monitoring and managing field. The model architecture for remote monitoring cloud platform of healthcare information (RMCPHI) was established firstly. Then the RMCPHI architecture was analyzed. Finally an efficient PSOSAA algorithm was proposed for the medical monitoring and managing application of cloud computing. Simulation results showed that our proposed scheme can improve the efficiency about 50%.

    The Internet of Things (IoT) has made it possible for devices around the world to acquire information and store it, in order to be able to use it at a later stage. However, this potential opportunity is often not exploited because of the excessively big interval between the data collection and the capability to process and analyse it. In this paper, we review the current IoT technologies, approaches and models in order to discover what challenges need to be met to make more sense of data. The main goal of this paper is to review the surveys related to IoT in order to provide well integrated and context aware intelligent services for IoT. Moreover, we present a state-of-the-art of IoT from the context aware perspective that allows the integration of IoT and social networks in the emerging Social Internet of Things (SIoT) term.

    Wireless Sensor Networks (WSNs) are generally used to collect information from the environment. The gathered data are delivered mainly to sinks or gateways that become the endpoints where applications can retrieve and process such data. However, applications would also expect from a WSN an event-driven operational model, so that they can be notified whenever occur some specific environmental changes instead of continuously analyzing the data provided periodically. In either operational model, WSNs represent a collection of interconnected objects, as outlined by the Internet of Things. Additionally, in order to fulfill the Internet of Things principles, Wireless Sensor Networks must have a virtual representation that allows indirect access to their resources, a model that should also include the virtualization of event sources in a WSN. Thus, in this paper a model for a virtual representation of event sources in a WSN is proposed. They are modeled as internet resources that are accessible by any internet application, following an Internet of Things approach. The model has been tested in a real implementation where a WSN has been deployed in an open neighborhood environment. Different event sources have been identified in the proposed scenario, and they have been represented following the proposed model.

    Internet of Things is a ubiquitous concept where physical objects are connected over the internet and are provided with unique identifiers to enable their self-identification to other devices and the ability to continuously generate data and transmit it over a network. Hence, the security of the network, data and sensor devices is a paramount concern in the IoT network as it grows very fast in terms of exchanged data and interconnected sensor nodes. This paper analyses the authentication and access control method using in the Internet of Things presented by Jing et al. (Authentication and Access Control in the Internet of Things. In Proceedings of the 2012 32nd International Conference on Distributed Computing Systems Workshops, Macau, China, 18-21 June 2012, pp. 588-592). According to our analysis, Jing et al.'s protocol is costly in the message exchange and the security assessment is not strong enough for such a protocol. Therefore, we propose improvements to the protocol to fill the discovered weakness gaps. The protocol enhancements facilitate many services to the users such as user anonymity, mutual authentication, and secure session key establishment. Finally, the performance and security analysis show that the improved protocol possesses many advantages against popular attacks, and achieves better efficiency at low communication cost.

    2009-01-01

    The Milnor-Hirzebruch class of a locally complete intersection X in an algebraic manifold M measures the difference between the (Poincare dual of the) Hirzebruch class of the virtual tangent bundle of X and, respectively, the Brasselet-Schuermann-Yokura (homology) Hirzebruch class of X. In this note, we calculate the Milnor-Hirzebruch class of a globally defined algebraic hypersurface X in terms of the corresponding Hirzebruch invariants of singular strata in a Whitney stratification of X. Our approach is based on Schuermann's specialization property for the motivic Hirzebruch class transformation of Brasselet-Schuermann-Yokura.

  10. Living together and living apart: the sexual lives of bryophytes.

    Science.gov (United States)

    Haig, David

    2016-10-19

    Haploid gametophytes of bryophytes spread by clonal growth but mate locally, within an area defined by the range of sperm movement. Rarity of establishment from spores or vegetative competition can result in unisexual populations unable to reproduce sexually. Females typically outcompete males, probably because females expend fewer resources than males on the production of gametes. Extreme sexual dimorphism-tiny males growing as epiphytes on much larger females-has evolved many times. Haploid selfing is common in bryophytes with bisexual gametophytes, and results in completely homozygous sporophytes. Spores from these sporophytes recapitulate the genotype of their single haploid parent. This process can be considered analogous to 'asexual' reproduction with 'sexual' reproduction occurring after rare outcrossing between haploid parents. Ferns also produce bisexual haploid gametophytes but, unlike bryophytes, haploid outcrossing predominates over haploid selfing. This difference is probably related to clonal growth and vegetative competition occurring in the haploid but not the diploid phase in bryophytes, but the reverse in ferns. Ferns are thereby subject to stronger inbreeding depression than bryophytes.This article is part of the themed issue 'Weird sex: the underappreciated diversity of sexual reproduction'.

The proposed system integrates RFID for tracking and tracing through a distributed architecture developed for heavy goods vehicles, and the sensors embedded in the SunSPOT platform for monitoring the goods transported based on the concept of the Internet of Things. This paper presents how the Internet of Things is integrated for improving terrestrial logistics offering a comprehensive and flexible architecture, with high scalability, according to the specific needs for reaching an item-level continuous monitoring solution. The major contribution from this work is the optimization of the Embedded Web Services based on RESTful (Web of Things for the access to TTM services at any time during the transportation of goods. Specifically, it has been extended the monitoring patterns such as observe and blockwise transfer for the requirements from the continuous conditional monitoring, and for the transfer of full inventories and partial ones based on conditional queries. In definitive, this work presents an evolution of the previous TTM solutions, which were limited to trailer identification and environment monitoring, to a solution which is able to provide an exhaustive item-level monitoring, required for several use cases. This exhaustive monitoring has required new communication capabilities through the Web of Things, which has been optimized with the use and improvement of a set of communications patterns.

    2014-10-01

    Full Text Available I examine, in this short paper, the work of Henri Bergson on Lucretius first published in 1884, and argue for its vital significance in understanding the development of his philosophical thinking. This publication was to serve as an introduction to extracts from Lucretius, for his students at Clermont-Ferrand, with a commentary and notes on the poetry, philosophy, the physics, language and text of his poem De Rerum Natura. In the published volume most of the overview of Lucretius by Bergson is given in the long preface, and this is followed by extracts in Latin, without translation into French, with comments on lines and individual words, which covers all the books of the original poem. By 1899 it had gone to a third edition, and was still in print until the 1960's. Copies today are very difficult to obtain, and only recently has a full electronic version become available on the Internet Archive, to which readers are here directly referred.

    2014-04-01

    Full Text Available Typical challenges that manufacturing enterprises are facing now are compounded by lack of timely, accurate, and consistent information of manufacturing resources. As a result, it is difficult to analyze the real-time production performance for the shop-floor. In this paper, the definition and overall architecture of the internet of manufacturing things is presented to provide a new paradigm by extending the techniques of internet of things (IoT to manufacturing field. Under this architecture, the real-time primitive events which occurred at different manufacturing things such as operators, machines, pallets, key materials, and so forth can be easily sensed. Based on these distributed primitive events, a critical event model is established to automatically analyze the real-time production performance. Here, the up-level production performance analysis is regarded as a series of critical events, and the real-time value of each critical event can be easily calculated according to the logical and sequence relationships among these multilevel events. Finally, a case study is used to illustrate how to apply the designed methods to analyze the real-time production performance.

    Huang, Chih-Yuan; Wu, Cheng-Hung

    2016-08-31

    The Internet of Things (IoT) is an infrastructure that interconnects uniquely-identifiable devices using the Internet. By interconnecting everyday appliances, various monitoring, and physical mashup applications can be constructed to improve human's daily life. In general, IoT devices provide two main capabilities: sensing and tasking capabilities. While the sensing capability is similar to the World-Wide Sensor Web, this research focuses on the tasking capability. However, currently, IoT devices created by different manufacturers follow different proprietary protocols and are locked in many closed ecosystems. This heterogeneity issue impedes the interconnection between IoT devices and damages the potential of the IoT. To address this issue, this research aims at proposing an interoperable solution called tasking capability description that allows users to control different IoT devices using a uniform web service interface. This paper demonstrates the contribution of the proposed solution by interconnecting different IoT devices for different applications. In addition, the proposed solution is integrated with the OGC SensorThings API standard, which is a Web service standard defined for the IoT sensing capability. Consequently, the Extended SensorThings API can realize both IoT sensing and tasking capabilities in an integrated and interoperable manner.

    2014-01-01

    Full Text Available Emerging Internet of Things (IoT/Machine-to-Machine (M2M systems require a transparent access to information and services through a seamless integration into the Future Internet. This integration exploits infrastructure and services found on the Internet by the IoT. On the one hand, the so-called Web of Things aims for direct Web connectivity by pushing its technology down to devices and smart things. On the other hand, the current and Future Internet offer stable, scalable, extensive, and tested protocols for node and service discovery, mobility, security, and auto-configuration, which are also required for the IoT. In order to integrate the IoT into the Internet, this work adapts, extends, and bridges using IPv6 the existing IoT building blocks (such as solutions from IEEE 802.15.4, BT-LE, RFID while maintaining backwards compatibility with legacy networked embedded systems from building and industrial automation. Specifically, this work presents an extended Internet stack with a set of adaptation layers from non-IP towards the IPv6-based network layer in order to enable homogeneous access for applications and services.

    Full Text Available This article deals with the class society, the emergence of the working class, its recognition as such and the education. Starts with a brief discussion of the positivist and materialist conceptions of society and historical dialectics, following, discusses the tests made by the working class in its long history to win his consciousness to another. If, from ancient times we live in a class society, this period is not the consciousness of belonging to a class of workers and much less for an action based on and consistent with this membership. This achievement goes through several times and struggles, whether against the nobility and aristocracy or against the bourgeoisie, who rub shoulders with many struggles to overthrow the forces of the Old Regime. However, these struggles the working class was also realizing that if the bourgeoisie, at various times, was interested in making alliances incidental to the conquest of power, definitely had no interest in sharing it. Thus, in the successive struggles and betrayals of the bourgeoisie, the working class was learning not only not believe in the promises and illusions of his former "comrades", but also claim the right to give the direction of their lives and "their destination".

    The Defence Medical Services (DMS) deployed on Op GRITROCK to Sierra Leone in support of the Ebola outbreak. This operation was the first large-scale DMS deployment since operations in Afghanistan ceased at the end of 2014. This type of operation revealed a number of ethical issues and challenges that the DMS had not faced for a long time. The ethical issues identified during the deployment are discussed in this article using the principalism approach of Beauchamp and Childress. Many of these issues were not identified prior to deployment, and troops were not adequately prepared. The article will outline the difficulties of using the principles of autonomy, beneficence, non-maleficence and justice during a public health emergency, and conclude with recommendations for ethical considerations that should be identified and mitigated against for future deployments to a public health emergency.

    Science.gov (United States)

    Wintroub, Michael

    2010-12-01

    Beginning with the meaning and use of the word "performance," this essay analyzes some of the ambiguities and tensions performance has historically engendered. These tensions were both social and epistemic and can be sketched out with relation to either the corrupting influences of performance as dissimulation and masquerade or its didactic possibilities as exemplary of morality, virtue, and truth. Following these tensions across the history of antitheatrical literature into early modern natural philosophy, the essay attempts to show some of the ways that natural philosophy was used to perform--regulate, discipline, and direct--its audience(s), while simultaneously being itself performed-through interlocking practices enacted by sites, objects, and humans--as demonstrative of the legitimacy of its social and epistemic authority.

    Positing complex adaptive systems made of agents with relations between them that can be composed, it follows that they can be described by gauge theories similar to elementary particle theory and general relativity. By definition, a universal dynamics is able to determine the time development of any such system without need for further specification. The possibilities are limited, but one of them - reproduction fork dynamics - describes DNA replication and is the basis of biological life on earth. It is a universal copy machine and a renormalization group fixed point. A universal equation of motion in continuous time is also presented.

    Full Text Available What is a book? Perhaps the notion refers firstly to an articulate format: to a substantive amount of printed pages bound together. Yet it also presupposes an articulate discourse: these pages are bound together for a reason, they have a single organizing principle in the conceptual as in the material level. The order in which the pages are arranged corresponds to the gradual spinning out of an overall sense. Furthermore, this coherent material and discursive entity circulates in social worlds, becoming charged with different attributes according to context. A consistent symbolic role in a given time and place may lead a book to operate as the book, or at least allow the generic idea of the book to act as a constant mediation in our relationship with any particular volume. Homi Bhabha, for example, has described how “the English book” – a blanket reference to canonical Western texts such as The Bible – impacted the postcolonial contexts in which it was introduced. According to Bhabha, the English book is emblematic of original truth, whether it be the word of God, the entrance into history by way of the written record, or the universal truths proclaimed by humanist literary traditions. All these truths tend to become reified by means of the foreign, imposed, printed text in contexts of reception that hold different configurations of orality and writing (102-122.

  3. A week for records… and things of record

    CERN Multimedia

    2015-01-01

    This week, the LHC set an important record on the way to the start of data taking for Run 2. At around 10.30 p.m. on Wednesday, 20 May, two bunches of particles were brought into collision at 13 TeV for the first time as part of the commissioning process for the systems that protect the detectors from stray particles. This milestone triggered ripples of excitement around the Laboratory and, coming right on schedule, is a clear sign that we are on course for physics data taking to start at the beginning of June. My congratulations go to all involved.   That was not the only record set this week: there was a sporting record as well.

  5. Remembrance of Things Past: Somali Roads to Police Development

    Directory of Open Access Journals (Sweden)

    Alice Hills

    2014-03-01

    Full Text Available Police reform is thought to require a police force to break with its past. This is notably so in the aftermath of conflict or regime change. In practice, however, most police forces are selectively reconstituted, and their development is influenced as much by legacy issues as by international standards filtered through local norms. This article uses the experience of Somalia’s three regional police forces to reconsider the relationship between past and present projects to build police authority and capacity, and what this says about institutional memory in the absence of documentation. In Somalia, as in other clan or tribal-based societies, police development is influenced by a blend of security levels, political imperatives, pragmatism, international resources and memories of past practices, with group experience playing a more significant role than institutional memory. The only identifiable general principle is the need for political settlements and tactical flexibility – that is, for stability.

  6. The Decline of Violence is Surely a Good Thing

    Directory of Open Access Journals (Sweden)

    Bill Philips

    2013-01-01

    Full Text Available Despite the widespread belief that the world grows increasingly violent, Steven Pinker's 2011 volume The Better Angels of Our Nature convincingly argues that the opposite is true. Tracing the history of humanity from its origins to the present day, Pinker shows how violence has declined, and that strong, stable government is the principal reason for this happening. The book briefly touches on the way literature may play a part in the reduction of violence through the transmission of empathy – the way in which stories about other people, even fictional people, teach us to comprehend more closely our fellow human beings. This article expands on Pinker's assertion and suggests that violence has also declined in literature, or become increasingly unacceptable to the point of rejection.

    Full Text Available The family Filoviridae contains several of the most deadly pathogens known to date and the current Ebola virus disease (EVD outbreak in Western Africa, due to Ebola virus (EBOV infection, highlights the need for active and broad research into filovirus pathogenesis. However, in comparison, the seven other known filovirus family members are significantly understudied. Many of these, including Marburgviruses and Ebolaviruses other than EBOV, are also highly virulent and fully capable of causing widespread epidemics. This review places the focus on these non-EBOV filoviruses, including known immunological and pathological data. The available animal models, research tools and currently available therapeutics will also be discussed along with an emphasis in the large number of current gaps in knowledge of these less highlighted filoviruses. It is evident that much research is yet to be done in order to bring the non-EBOV filovirus field to the forefront of current research and, importantly, to the development of more effective vaccines and therapeutics to combat potential future outbreaks.

  9. Are radioisotope shortages a thing of the past?

    Energy Technology Data Exchange (ETDEWEB)

    Peykov, Pavel; Cameron, Ron [OECD Nuclear Energy Agency, Issy-les-Moulineaux (France)

    2014-10-15

    Since June 2009, the NEA and its High-level Group on the Security of Supply of Medical Radioisotopes (HLG-MR) have examined the causes of {sup 99}Mo/{sup 99m}Tc supply shortages and developed a policy approach, including principles and supporting recommendations to address those causes. The NEA has also reviewed the global {sup 99}Mo/{sup 99m}Tc supply situation periodically, using the most up-to-date data from supply chain participants, to highlight periods of reduced supply and underscore the case for implementing the HLG-MR policy approach in a timely and globally-consistent manner. In 2012, the NEA released a {sup 99}Mo supply and demand update for the period up to 2030 (A Supply and Demand Update of the Molybdenum-99 Market, OECD/NEA, 2012), identifying periods of low supply relative to demand. This paper presents the preliminary results from an updated {sup 99}Mo supply and demand forecast, focusing on the potentially critical 2015-2020 period, when two major {sup 99}Mo producers (the NRU reactor in Canada and the OSIRIS reactor in France) are scheduled to cease {sup 99}Mo irradiations. On the demand side, the NEA had previously released a study with the results from a global survey of future demand for {sup 99}Mo/{sup 99m}Tc (OECD-NEA, 2011), devising a scenario based on a data assessment by an expert advisory group. In the current analysis, the expected demand growth rate and total demand have been modified, based on the latest information from supply chain participants. On the supply side, the NEA has updated the list of current and planned new {sup 99}Mo/{sup 99m}Tc irradiation and processing projects. The modelling results incorporate revisions to production start/end dates, potential additional projects, and impacts of converting to the use of low-enriched uranium (LEU) targets on {sup 99}Mo/{sup 99m}Tc capacity and production. The supply forecast horizon (2015 to 2020) has been chosen to reflect upcoming, important changes in global production capacity

  12. Coppice forests, or the changeable aspect of things, a review

    Directory of Open Access Journals (Sweden)

    Gianfranco Fabbio

    2016-11-01

    Full Text Available Coppiced forests were the main source of firewood, brushwood, and charcoal for rural and urban settlements’ basic needs such as cooking food and domestic heating for thousands of years and up to the mid-20th century in many European countries and, specifically, in Mediterranean countries. The global diffusion of fossil fuels reduced this leadership and the coppice system turned, to some extent, to a reminder of the past. Nowadays, the ongoing global changes and the related green-economy issues call for resilient systems and effective bio-energy producers. These issues have caused a second turning point and the coppice has returned fifty years later to play a role. A review of the silvicultural system has been carried out with a special focus on the changes which have occurred in between, taking Italy as a consistent case-study. The analysis is mainly framed upon the long-term research trials established by the CREA-Forestry Research Centre in the late sixties, to find out adaptive management strategies and overcome the system’s crisis. The findings and further knowledge achieved so far on the dynamics and functioning of coppice forests in the outgrown phase, both as natural evolutive patterns and silviculture-driven processes, are highlighted in this paper. They provide useful tools to handle the management shift regarding forthcoming issues, i.e. the current role attributable to the coppice system within the changing environment and the renewable energy demand. The basic features of each management area and their complementarities within the current framework are outlined.

  15. Design and Implement AN Interoperable Internet of Things Application Based on AN Extended Ogc Sensorthings Api Standard

    Science.gov (United States)

    Huang, C. Y.; Wu, C. H.

    2016-06-01

    The Internet of Things (IoT) is an infrastructure that interconnects uniquely-identifiable devices using the Internet. By interconnecting everyday appliances, various monitoring and physical mashup applications can be constructed to improve people's daily life. However, IoT devices created by different manufacturers follow different proprietary protocols and cannot communicate with each other. This heterogeneity issue causes different products to be locked in multiple closed ecosystems that we call IoT silos. In order to address this issue, a common industrial solution is the hub approach, which implements connectors to communicate with IoT devices following different protocols. However, with the growing number of proprietary protocols proposed by device manufacturers, IoT hubs need to support and maintain a lot of customized connectors. Hence, we believe the ultimate solution to address the heterogeneity issue is to follow open and interoperable standard. Among the existing IoT standards, the Open Geospatial Consortium (OGC) SensorThings API standard supports comprehensive conceptual model and query functionalities. The first version of SensorThings API mainly focuses on connecting to IoT devices and sharing sensor observations online, which is the sensing capability. Besides the sensing capability, IoT devices could also be controlled via the Internet, which is the tasking capability. While the tasking capability was not included in the first version of the SensorThings API standard, this research aims on defining the tasking capability profile and integrates with the SensorThings API standard, which we call the extended-SensorThings API in this paper. In general, this research proposes a lightweight JSON-based web service description, the "Tasking Capability Description", allowing device owners and manufacturers to describe different IoT device protocols. Through the extended- SensorThings API, users and applications can follow a coherent protocol to control Io

    Full Text Available This paper examines the semiotics of props and other physical items in Plautus’ Curculio. The play is over-determined with props: a candle, a door, fragrant wine, water, a ring, which comes in twice (and has a twin, a letter to go with it, a seal with represented elephant-slaying sword, a missing eye, a bad gut, animal names, like the wolfy banker Lyco, and the weevil-parasite Curculio, and a property manager who comes out for a little chat with the audience about the real-life Rome they can see around them. I am particularly concerned with the most powerfully metatheatrical and metapoetic elements, including the preternaturally quiet door, and the ring which has a life of its own weaving through the play and indeed through the comic tradition.

    Nowadays, we daily meet new wireless technologies. This is often achieved through the use of RFID (Radio Frequency IDentification) tags and wireless sensors. Our environment and surrounding objects become communicating. New applications thus arise in domains such as logistic, health, rescue and environment preservation. Embedding such devices in various industrial goods could lead to a world in which objects communicate and interact with other objects and with people, i.e. the so-called "Internet of things". This article describes the various types of RFID tags, and the hot topic for research and some examples of applications are given.

In addition to looking at gendered space, then, understanding a city requires considering the dynamic relationship between the seen and the unseen. And in order to understand this relationship, we need more than preconceived pronouncements about how the city works, or about how gender and class work on space. Rather, we need rich, fine-grained ethnography that traces the dynamic intersections of gender, space, and class in a city. To do such ethnography properly requires peering beyond the surface appearances of the city and listening intently to the everyday lives lived within it. The four new ethnographic perspectives on gender, class, and space in Ho Chi Minh City discussed in this essay all offer ways to see the city again. Three of them do this by looking at class and gender, and one does it by rethinking how we make maps; two of them are by anthropologists, one by a sociologist, and one by an urban planner.

    2015-01-01

    Recently, researchers are focusing on a new use of the Internet called the Internet of Things (IoT), in which enabled electronic devices can be remotely accessed over the Internet. As the realization of IoT concept is still in its early stages, manufacturers of Internet-connected devices and IoT web service providers are defining their proprietary protocols based on their targeted applications. Consequently, IoT becomes heterogeneous in terms of hardware capabilities and communication protocols. Addressing these heterogeneities by following open standards is a necessary step to communicate with various IoT devices. In this research, we assess the feasibility of applying existing open standards on resource-constrained IoT devices. The standard protocols developed in this research are OGC PUCK over Bluetooth, TinySOS, SOS over CoAP, and OGC SensorThings API. We believe that by hosting open standard protocols on IoT devices, not only do the devices become self-describable, self-contained, and interoperable, but innovative applications can also be easily developed with standardized interfaces. In addition, we use memory consumption, request message size, response message size, and response latency to benchmark the efficiency of the implemented protocols. In all, this research presents and evaluates standard-based solutions to better understand the feasibility of applying existing standards to the IoT vision. PMID:26402683

    Current challenges demand a profound restructuration of the global healthcare system. A more efficient system is required to cope with the growing world population and increased life expectancy, which is associated with a marked prevalence of chronic neurological disorders such as Parkinson's disease (PD). One possible approach to meet this demand is a laterally distributed platform such as the Internet of Things (IoT). Real-time motion metrics in PD could be obtained virtually in any scenario by placing lightweight wearable sensors in the patient's clothes and connecting them to a medical database through mobile devices such as cell phones or tablets. Technologies exist to collect huge amounts of patient data not only during regular medical visits but also at home during activities of daily life. These data could be fed into intelligent algorithms to first discriminate relevant threatening conditions, adjust medications based on online obtained physical deficits, and facilitate strategies to modify disease progression. A major impact of this approach lies in its efficiency, by maximizing resources and drastically improving the patient experience. The patient participates actively in disease management via combined objective device- and self-assessment and by sharing information within both medical and peer groups. Here, we review and discuss the existing wearable technologies and the Internet-of-Things concept applied to PD, with an emphasis on how this technological platform may lead to a shift in paradigm in terms of diagnostics and treatment.

    2015-01-01

    Full Text Available UAVs, Unmanned Aerial Vehicles, have gained significant attention recently, due to the increasingly growing range of applications. Most UAVs use radio frequency transmission to communicate with the ground station to receive commands and send data. However, this model of communication restricts the user to being in specific locations and limits missions to narrow areas. This paper proposes a Cloud Computing (CC integration where the UAVs become part of the cloud infrastructure and can be accessed ubiquitously. This concept is similar to the Internet of Things (IoT where smart objects are connected to the Internet and are given unique identification. Moreover, to provide an appropriate way of communication, UAV resources are developed as web services. They provide their resources and services through a uniform interface using the RESTful HTTP architecture. This concept is relevant to the Web of Things (WoT that provides smart objects with interfaces to be accessed through the World Wide Web (WWW. However, in UAVs, not only the web services are computational services but they are also physical elements affecting and affected by the real world environment.

    It has been more than fifteen years since the term Internet of Things (IoT) was introduced to the public. However, despite the efforts of research groups and innovative corporations, still today it is not possible to say that IoT is upon us. This is mainly due to the fact that a unified IoT architecture has not been yet clearly defined and there is no common agreement in defining protocols and standards for all IoT parts. The framework that current IoT platforms use consists mostly in technol...

  14. Proximity-Based Asynchronous Messaging Platform for Location-Based Internet of Things Service

    2016-07-01

    Full Text Available The Internet of Things (IoT opens up tremendous opportunities to provide location-based applications. However, despite the services around a user being physically adjacent, common IoT platforms use a centralized structure, like a cloud-computing architecture, which transfers large amounts of data to a central server. This raises problems, such as traffic concentration, long service latency, and high communication cost. In this paper, we propose a physical distance-based asynchronous messaging platform that specializes in processing personalized data and location-based messages. The proposed system disperses traffic using a location-based message-delivery protocol, and has high stability.

    2014-08-01

    Full Text Available Internet of Things is a ubiquitous concept where physical objects are connected over the internet and are provided with unique identifiers to enable their self-identification to other devices and the ability to continuously generate data and transmit it over a network. Hence, the security of the network, data and sensor devices is a paramount concern in the IoT network as it grows very fast in terms of exchanged data and interconnected sensor nodes. This paper analyses the authentication and access control method using in the Internet of Things presented by Jing et al. According to our analysis, Jing et al.’s protocol is costly in the message exchange and the security assessment is not strong enough for such a protocol. Therefore, we propose improvements to the protocol to fill the discovered weakness gaps. The protocol enhancements facilitate many services to the users such as user anonymity, mutual authentication, and secure session key establishment. Finally, the performance and security analysis show that the improved protocol possesses many advantages against popular attacks, and achieves better efficiency at low communication cost.

    The time of our conception is when we are most vulnerable to survival and growing as a healthy human being. Genetic and environmental effects on gametes and the developing embryo can be literally life-and-death events with regard to the successful outcome of pregnancy. In the past decade, we have also understood that environmental factors under which the gametes grow and the embryo develops have lifelong implications with regard to developmental origins of health and disease. We now know that parenting begins before conception in that a compromised egg or sperm from either parent can alter the trajectory of development even if the embryo and intrauterine environment is optimal. There are now a large number of factors known to impact on the gametes to adversely affect them, including obesity, nutrition, cigarette smoking and environmental pollutants. The increasing use of in vitro fertilisation across the world exposes developing embryos to less than optimal environmental conditions through altered culture media, gases and potential pollutants from plastics, air and water. Many of these environmental exposures have not undergone experimental investigation and yet widely implemented in thousands of laboratories across the world. There have been many attempts to set up periconception planning either through the health service, the print and electronic media or through government action. We as a profession, as well as our Colleges, could do much better job in this area of preventative medicine by developing better guidelines and education for professional colleagues, the health service and the community.

    Full Text Available This study aim to give an analysis of the threats to privacy in wireless sensors in the context of the Internet of things and we review the pros and cons of some of the proposed solutions in order to ensure privacy. We propose a solution for the management of security keys based on symmetric encryption, taking into account two important factors, the sensors resources constraints and their mobility being linked to the patient body that may move occasionally. Tests gave significant results confirm that our proposed solution is secure, energy efficient and unable to deal with mobility. The field of healthcare knew an important development due to the evolution of the technology used in its applications, from sophisticated equipment in the operating rooms, to diagnostic and analysis equipment offering accurate and effective results. Among devices that have contributed to the development of the field of healthcare is the mobile monitoring sensors that are placed on the patient's body. By the emergence of the Internet of Things, it became possible to access to them remotely, so the possibility of offering patients a continuous and real-time monitoring and keep track of his health condition wherever he goes, from inside his home, in the street, in the workplace, etc. However, the main drawback of these applications is the lack of consideration of data security and privacy. The nature of these sensors from a wireless connection and limited capacities, making them vulnerable to a range of attacks aimed at eavesdrop or tamper patients’ personal information.

    Zheng, Yan

    2015-03-01

    Internet of things (IoT), focusing on providing users with information exchange and intelligent control, attracts a lot of attention of researchers from all over the world since the beginning of this century. IoT is consisted of large scale of sensor nodes and data processing units, and the most important features of IoT can be illustrated as energy confinement, efficient communication and high redundancy. With the sensor nodes increment, the communication efficiency and the available communication band width become bottle necks. Many research work is based on the instance which the number of joins is less. However, it is not proper to the increasing multi-join query in whole internet of things. To improve the communication efficiency between parallel units in the distributed sensor network, this paper proposed parallel query optimization algorithm based on distribution attributes cost graph. The storage information relations and the network communication cost are considered in this algorithm, and an optimized information changing rule is established. The experimental result shows that the algorithm has good performance, and it would effectively use the resource of each node in the distributed sensor network. Therefore, executive efficiency of multi-join query between different nodes could be improved.

  8. A DHT-Based Discovery Service for the Internet of Things

    2012-01-01

    Full Text Available Current trends towards the Future Internet are envisaging the conception of novel services endowed with context-aware and autonomic capabilities to improve end users’ quality of life. The Internet of Things paradigm is expected to contribute towards this ambitious vision by proposing models and mechanisms enabling the creation of networks of “smart things” on a large scale. It is widely recognized that efficient mechanisms for discovering available resources and capabilities are required to realize such vision. The contribution of this work consists in a novel discovery service for the Internet of Things. The proposed solution adopts a peer-to-peer approach for guaranteeing scalability, robustness, and easy maintenance of the overall system. While most existing peer-to-peer discovery services proposed for the IoT support solely exact match queries on a single attribute (i.e., the object identifier, our solution can handle multiattribute and range queries. We defined a layered approach by distinguishing three main aspects: multiattribute indexing, range query support, peer-to-peer routing. We chose to adopt an over-DHT indexing scheme to guarantee ease of design and implementation principles. We report on the implementation of a Proof of Concept in a dangerous goods monitoring scenario, and, finally, we discuss test results for structural properties and query performance evaluation.

    2016-01-01

    With the development of the Internet of Things (IoT), resources and applications based on it have emerged on a large scale. However, most efforts are “silo” solutions where devices and applications are tightly coupled. Infrastructures are needed to connect sensors to the Internet, open up and break the current application silos and move to a horizontal application mode. Based on the concept of Web of Things (WoT), many infrastructures have been proposed to integrate the physical world with the Web. However, issues such as no real-time guarantee, lack of fine-grained control of data, and the absence of explicit solutions for integrating heterogeneous legacy devices, hinder their widespread and practical use. To address these issues, this paper proposes a WoT resource framework that provides the infrastructures for the customizable openness and sharing of users’ data and resources under the premise of ensuring the real-time behavior of their own applications. The proposed framework is validated by actual systems and experimental evaluations. PMID:27690038

    Full Text Available The common vision of smart systems today, is by and large associated with one single concept, the internet of things (IoT, where the whole physical infrastructure is linked with intelligent monitoring and communication technologies through the use of wireless sensors. In such an intelligent vibrant system, sensors are connected to send useful information and control instructions via distributed sensor networks. Wireless sensors have an easy deployment and better flexibility of devices contrary to wired setup. With the rapid technological development of sensors, wireless sensor networks (WSNs will become the key technology for IoT and an invaluable resource for realizing the vision of Internet of things (IoT paradigm. It is also important to consider whether the sensors of a WSN should be completely integrated into IoT or not. New security challenges arise when heterogeneous sensors are integrated into the IoT. Security needs to be considered at a global perspective, not just at a local scale. This paper gives an overview of sensor integration into IoT, some major security challenges and also a number of security primitives that can be taken to protect their data over the internet

    Full Text Available Internet of Things (IoT is emerging as a significant technology in shaping the future by connecting physical devices or things with the web. It also presents various opportunities for the intersection of other technological trends which can allow it to become even more intelligent and efficient. In this paper, we focus our attention on the integration of Intelligent Conversational Software Agents or Chatbots with IoT. Prior literature has covered various applications, features, underlying technologies and known challenges of IoT. On the other hand, Chatbots are a relatively new concept, being widely adopted due to significant progress in the development of platforms and frameworks. The novelty of this paper lies in the specific integration of Chatbots in the IoT scenario. We analyzed the shortcomings of existing IoT systems and put forward ways to tackle them by incorporating chatbots. A general architecture is proposed for implementing such a system, as well as platforms and frameworks – both commercial and open source – which allow for the implementation of such systems. Identification of the newer challenges and possible future research directions with this new integration have also been addressed.

    Aroua TAAMALLAH

    2015-12-01

    Full Text Available Nowadays, learning is more and more taking place anywhere and anytime. This implies that e-learning environments are expanded from only virtual learning environments to both virtual and physical ones. Thanks to the evolution of Internet, ICT (Information and Communication Technology and Internet of Things, new learning scenarios could be experienced by learners either individually or collaboratively. These learning scenarios are Pervasive in such a way that they allow to mix virtual and physical learning environments as well. They are therefore characterized by possible interactions of the learner with the physical environment, the Learner's contextual data detection as well as the adaptation of pedagogical strategies and services according to this context. This paper aims to take advantage of this trend and keep up also with existing e-Learning standards such as IMS LD and LOM. The solution proposed is therefore to extend these standards models with that of Internet of Things and to provide an adaptation approach of learning activities based on learner's context and her/his track using the eXperience API. In this context and in order to allow both reasoning capabilities and interoperability between the proposed models Ontological representations and implementation are therefore proposed. Moreover a technical architecture highlighting the required software components and their interactions is provided. And finally, a relevant pervasive learning scenario is implemented and experimented.

    2013-11-14

    The Internet of Things (IoT) is a networking paradigm where interconnected, smart objects continuously generate data and transmit it over the Internet. Much of the IoT initiatives are geared towards manufacturing low-cost and energy-efficient hardware for these objects, as well as the communication technologies that provide objects interconnectivity. However, the solutions to manage and utilize the massive volume of data produced by these objects are yet to mature. Traditional database management solutions fall short in satisfying the sophisticated application needs of an IoT network that has a truly global-scale. Current solutions for IoT data management address partial aspects of the IoT environment with special focus on sensor networks. In this paper, we survey the data management solutions that are proposed for IoT or subsystems of the IoT. We highlight the distinctive design primitives that we believe should be addressed in an IoT data management solution, and discuss how they are approached by the proposed solutions. We finally propose a data management framework for IoT that takes into consideration the discussed design elements and acts as a seed to a comprehensive IoT data management solution. The framework we propose adapts a federated, data- and sources-centric approach to link the diverse Things with their abundance of data to the potential applications and services that are envisioned for IoT.

    Directory of Open Access Journals (Sweden)

    Warren Carter

    2014-02-01

    Full Text Available This article observes the rarely-discussed phenomenon that the Marcan paying-the-tax scene refers to tax in the singular, whilst the concluding saying uses the plural ‘the things of Caesar and of God’. The article accounts for this phenomenon by means of developing traditions. The section under the heading ‘Mark’s scene and saying about taxes (12:13–17’ counters the common claim that scene and saying originated as a unit from the historical Jesus. It proposes that whilst the saying may have originated with Jesus, the scene as we have it did not. The section under the heading ‘Social memory, orality, and a multi-referential saying?’ suggests some contexts that the saying about the things of Caesar addressed pre-Mark. And under the section ‘Trauma and Mark’s scene’ it is argued that Mark created a unit comprising scene and saying to negotiate the ‘ trauma’ of the 66–70 war. The unit evaluates freshly-asserted Roman power as idolatrous and blasphemous whilst simultaneously authorising the continued involvement of Jesus-believers in imperial society.

    2017-01-01

    Full Text Available Under unreliable constrained wireless networks for Internet of Things (IoT environments, the loss of the signaling message may frequently occur. Mobile Internet Protocol version 6 (MIPv6 and its variants do not consider this situation. Consequently, as a constrained device moves around different wireless networks, its Internet Protocol (IP connectivity may be frequently disrupted and power can be drained rapidly. This can result in the loss of important sensing data or a large delay for time-critical IoT services such as healthcare monitoring and disaster management. This paper presents a reliable mobility management mechanism in Internet of Things environments with lossy low-power constrained device and network characteristics. The idea is to use the Internet Engineering Task Force (IETF Constrained Application Protocol (CoAP retransmission mechanism to achieve both reliability and simplicity for reliable IoT mobility management. Detailed architecture, algorithms, and message extensions for reliable mobility management are presented. Finally, performance is evaluated using both mathematical analysis and simulation.

    Full Text Available The security of Internet of Things (IoT has received extensive attention recently. This paper presents a novel analytical model to investigate the eavesdropping attacks in Wireless Net of Things (WNoT. Our model considers various channel conditions, including the path loss, the shadow fading effect, and Rayleigh fading effect. Besides, we also consider the eavesdroppers in WNoT equipped with either omnidirectional antennas or directional antennas. Extensive simulation results show that our model is accurate and effective to model the eavesdropping attacks in WNoT. Besides, our results also indicate that the probability of eavesdropping attacks heavily depends on the shadow fading effect, the path loss effect, Rayleigh fading effect, and the antenna models. In particular, we find that the shadow fading effect is beneficial to the eavesdropping attacks while both the path loss effect and Rayleigh fading effect are detrimental. Besides, using directional antennas at eavesdroppers can also increase the eavesdropping probability. Our results offer some useful implications on designing antieavesdropping schemes in WNoT.

    Full Text Available The Internet of Things benefits from an increasing number of interconnected technical devices. This has led to the existence of so-called smart environments, which encompass one or more devices sensing, acting, and automatically performing different tasks to enable their self-organization. Smart environments are divided into two parts: the physical environment and its digital representation, oftentimes referred to as digital twin. However, the automated binding and monitoring of devices of smart environments are still major issues. In this article we present a method and system architecture to cope with these challenges by enabling (i easy modeling of sensors, actuators, devices, and their attributes, (ii dynamic device binding based on their type, (iii the access to devices using different paradigms, and (iv the monitoring of smart environments in regard to failures or changes. We furthermore provide a prototypical implementation of the introduced approach.
