    Integrating the sensing capabilities in Internet Protocol network will open the opportunities to build a wide range of novel multimedia applications. The problem when using sensors (e.g. temperature sensor, camera, audio, humidity, etc.) connected to the network is to know dynamically at any time if they are always connected or not, what type of data they can transmit and where they are geographically located. This paper describes an application enabler: IMS Sensor Search Engine Enabler (iSSEE), which allows IMS applications using sensors and IMS based devices, to get information about the sensor availability, its location and the type of the sensor. Using data collected by sensors and from the web, mash-ups convergent applications use cases are proposed by combining the contents from heterogeneous data.

    More and more sensors are getting Internet connected. Examples are cameras on cell phones, CCTV cameras for traffic control as well as dedicated security and defense sensor systems. Due to the steadily increasing data volume, human exploitation of all this sensor data is impossible for effective mission execution. Smart access to all sensor data acts as enabler for questions such as "Is there a person behind this building" or "Alert me when a vehicle approaches". The GOOSE concept has the ambition to provide the capability to search semantically for any relevant information within "all" (including imaging) sensor streams in the entire Internet of sensors. This is similar to the capability provided by presently available Internet search engines which enable the retrieval of information on "all" web pages on the Internet. In line with current Internet search engines any indexing services shall be utilized cross-domain. The two main challenge for GOOSE is the Semantic Gap and Scalability. The GOOSE architecture consists of five elements: (1) an online extraction of primitives on each sensor stream; (2) an indexing and search mechanism for these primitives; (3) a ontology based semantic matching module; (4) a top-down hypothesis verification mechanism and (5) a controlling man-machine interface. This paper reports on the initial GOOSE demonstrator, which consists of the MES multimedia analysis platform and the CORTEX action recognition module. It also provides an outlook into future GOOSE development.

    In this research project, completely new sensors wer developed, as there was nothing comparable on the market. The development was carried out by the partners Sick and Weidmueller, with the support of MB DATA for mining details and mining law authorisation. With regard to the developed sensors, the optical sensor from the firm of Sick represents a very capable equipment. By contrast, the ultrasonic sensors have not been developed ready for authorisation yet, but the management of the firm of Weidmueller states that they will continue development in 1994. The sensor system described here was developed in the context of the research project `Automation in mining/sensor for measuring the free through cross section`. The aim of this research contract was to develop an equipment which should succeed in detecting any obstacles on the route of a vehicle. In the case of the optical sensor, this project succeeded in doing this. (orig.)

    2015-03-01

    Full Text Available The Wireless Sensor Network similarity search problem has received considerable research attention due to sensor hardware imprecision and environmental parameter variations. Most of the state-of-the-art distributed data centric storage (DCS schemes lack optimization for similarity queries of events. In this paper, a DCS scheme with metric based similarity searching (DCSMSS is proposed. DCSMSS takes motivation from vector distance index, called iDistance, in order to transform the issue of similarity searching into the problem of an interval search in one dimension. In addition, a sector based distance routing algorithm is used to efficiently route messages. Extensive simulation results reveal that DCSMSS is highly efficient and significantly outperforms previous approaches in processing similarity search queries.

    The internet plays an important role in a growing number of medical applications. Finding relevant information is not always easy as the amount of available information on the Web is rising quickly. Even the best Search Engines can only collect links to a fraction of all existing Web pages. In addition, many of these indexed documents have been changed or deleted. The vast majority of information on the Web is not searchable with conventional methods. New search strategies, technologies and standards are combined in Intelligent Search Agents (ISA) an Robots, which can retrieve desired information in a specific approach. Conclusion: The article describes differences between ISAs and conventional Search Engines and how communication between Agents improves their ability to find information. Examples of existing ISAs are given and the possible influences on the current and future work in radiology is discussed. (orig.)

  11. Using insect electroantennogram sensors on autonomous robots for olfactory searches.

    2014-08-04

    Robots designed to track chemical leaks in hazardous industrial facilities or explosive traces in landmine fields face the same problem as insects foraging for food or searching for mates: the olfactory search is constrained by the physics of turbulent transport. The concentration landscape of wind borne odors is discontinuous and consists of sporadically located patches. A pre-requisite to olfactory search is that intermittent odor patches are detected. Because of its high speed and sensitivity, the olfactory organ of insects provides a unique opportunity for detection. Insect antennae have been used in the past to detect not only sex pheromones but also chemicals that are relevant to humans, e.g., volatile compounds emanating from cancer cells or toxic and illicit substances. We describe here a protocol for using insect antennae on autonomous robots and present a proof of concept for tracking odor plumes to their source. The global response of olfactory neurons is recorded in situ in the form of electroantennograms (EAGs). Our experimental design, based on a whole insect preparation, allows stable recordings within a working day. In comparison, EAGs on excised antennae have a lifetime of 2 hr. A custom hardware/software interface was developed between the EAG electrodes and a robot. The measurement system resolves individual odor patches up to 10 Hz, which exceeds the time scale of artificial chemical sensors. The efficiency of EAG sensors for olfactory searches is further demonstrated in driving the robot toward a source of pheromone. By using identical olfactory stimuli and sensors as in real animals, our robotic platform provides a direct means for testing biological hypotheses about olfactory coding and search strategies. It may also prove beneficial for detecting other odorants of interests by combining EAGs from different insect species in a bioelectronic nose configuration or using nanostructured gas sensors that mimic insect antennae.

  14. Phonon Sensor Dynamics for Cryogenic Dark Matter Search Experiment

    Yen, Jeffrey [Stanford Univ., CA (United States)

    2015-01-01

    Understanding the quasiparticle diffusion process inside sputtered aluminum (Al thin films (~ 0.1-1 μm is critical for the Cryogenic Dark Matter Search (CDMS experiment to further optimize its detectors to directly search for dark matter. An initial study with Al films was undertaken by our group ~ 20 years ago, but some important questions were not answered at the time. This thesis can be considered a continuation of that critical study. The CDMS experiment utilizes high purity silicon and germanium crystals to simultaneously measure ionization and phonons created by particle interactions. In addition to describing some of the rich physics involved in simultaneously detecting ionization and phonons with a CDMS detector, this thesis focuses on the detailed physics of the phonon sensors themselves, which are patterned onto CDMS detector surfaces. CDMS detectors use thin sputtered Al films to collect phonon energy when it propagates to the surfaces of the detector crystals. The phonon energy breaks Cooper pairs and creates quasiparticles (qps). These qps diffuse until they get trapped in an proximitized “overlap” region where lower-Tc tungsten films connect to the Al film. These tungsten films are the transition edge sensors (W-TESs CDMS uses to readout phonon signals. We performed a wide range of experiments using several sets of test devices designed and fabricated specifically for this work. The devices were used mostly to study quasiparticle (qp transport in Al films and qp transmission through Al/W interfaces. The results of this work are being used to optimize the design of detectors for SuperCDMS SNOLAB. This thesis is intended for CDMS collaborators who are interested in knowing more about the detailed fundamentals of how our phonon sensors work so they can take full advantage of their benefits. However, this work can also be read by general readers who are interested in particle detection using TES technology. This thesis contains eight chapters. The

    new lower bound on the performance of adaptive controllers in these scenarios, develop algorithms for computing solutions to this lower bound, and use these algorithms as part of a RH controller for sensor allocation in the presence of moving objects We also consider an adaptive Search problem where sensing actions are continuous and the underlying measurement space is also continuous. We extend our previous hierarchical decomposition approach based on performance bounds to this problem and develop novel implementations of Stochastic Dynamic Programming (SDP) techniques to solve this problem. Our algorithms are nearly two orders of magnitude faster than previously proposed approaches and yield solutions of comparable quality. For supervisory control, we discuss how human operators can work with and augment robotic teams performing these tasks. Our focus is on how tasks are partitioned among teams of robots and how a human operator can make intelligent decisions for task partitioning. We explore these questions through the design of a game that involves robot automata controlled by our algorithms and a human supervisor that partitions tasks based on different levels of support information. This game can be used with human subject experiments to explore the effect of information on quality of supervisory control.

  16. Generalized Voronoi Partition Based Multi-Agent Search using Heterogeneous Sensors

    CERN Document Server

    Guruprasad, K R

    2009-01-01

    In this paper we propose search strategies for heterogeneous multi-agent systems. Multiple agents, equipped with communication gadget, computational capability, and sensors having heterogeneous capabilities, are deployed in the search space to gather information such as presence of targets. Lack of information about the search space is modeled as an uncertainty density distribution. The uncertainty is reduced on collection of information by the search agents. We propose a generalization of Voronoi partition incorporating the heterogeneity in sensor capabilities, and design optimal deployment strategies for multiple agents, maximizing a single step search effectiveness. The optimal deployment forms the basis for two search strategies, namely, {\\em heterogeneous sequential deploy and search} and {\\em heterogeneous combined deploy and search}. We prove that the proposed strategies can reduce the uncertainty density to arbitrarily low level under ideal conditions. We provide a few formal analysis results related ...

  17. Pure random search for ambient sensor distribution optimisation in a smart home environment.

    2011-01-01

    Smart homes are living spaces facilitated with technology to allow individuals to remain in their own homes for longer, rather than be institutionalised. Sensors are the fundamental physical layer with any smart home, as the data they generate is used to inform decision support systems, facilitating appropriate actuator actions. Positioning of sensors is therefore a fundamental characteristic of a smart home. Contemporary smart home sensor distribution is aligned to either a) a total coverage approach; b) a human assessment approach. These methods for sensor arrangement are not data driven strategies, are unempirical and frequently irrational. This Study hypothesised that sensor deployment directed by an optimisation method that utilises inhabitants' spatial frequency data as the search space, would produce more optimal sensor distributions vs. the current method of sensor deployment by engineers. Seven human engineers were tasked to create sensor distributions based on perceived utility for 9 deployment scenarios. A Pure Random Search (PRS) algorithm was then tasked to create matched sensor distributions. The PRS method produced superior distributions in 98.4% of test cases (n=64) against human engineer instructed deployments when the engineers had no access to the spatial frequency data, and in 92.0% of test cases (n=64) when engineers had full access to these data. These results thus confirmed the hypothesis.

  18. Road Target Search and Tracking with Gimballed Vision Sensor on an Unmanned Aerial Vehicle

    Directory of Open Access Journals (Sweden)

    Fredrik Gustafsson

    2012-07-01

    Full Text Available This article considers a sensor management problem where a number of road bounded vehicles are monitored by an unmanned aerial vehicle (UAV with a gimballed vision sensor. The problem is to keep track of all discovered targets and simultaneously search for new targets by controlling the pointing direction of the vision sensor and the motion of the UAV. A planner based on a state-machine is proposed with three different modes; target tracking, known target search, and new target search. A high-level decision maker chooses among these sub-tasks to obtain an overall situational awareness. A utility measure for evaluating the combined search and target tracking performance is also proposed. By using this measure it is possible to evaluate and compare the rewards of updating known targets versus searching for new targets in the same framework. The targets are assumed to be road bounded and the road network information is used both to improve the tracking and sensor management performance. The tracking and search are based on flexible target density representations provided by particle mixtures and deterministic grids.

  19. A UAV routing and sensor control optimization algorithm for target search

    Science.gov (United States)

    Collins, Gaemus E.; Riehl, James R.; Vegdahl, Philip S.

    2007-04-01

    An important problem in unmanned air vehicle (UAV) and UAV-mounted sensor control is the target search problem: locating target(s) in minimum time. Current methods solve the optimization of UAV routing control and sensor management independently. While this decoupled approach makes the target search problem computationally tractable, it is suboptimal. In this paper, we explore the target search and classification problems by formulating and solving a joint UAV routing and sensor control optimization problem. The routing problem is solved on a graph using receding horizon optimal control. The graph is dynamically adjusted based on the target probability distribution function (PDF). The objective function for the routing optimization is the solution of a sensor control optimization problem. An optimal sensor schedule (in the sense of maximizing the viewed target probability mass) is constructed for each candidate flight path in the routing control problem. The PDF of the target state is represented with a particle filter and an "occupancy map" for any undiscovered targets. The tradeoff between searching for undiscovered targets and locating tracks is handled automatically and dynamically by the use of an appropriate objective function. In particular, the objective function is based on the expected amount of target probability mass to be viewed.

  20. A trust-based sensor allocation algorithm in cooperative space search problems

    Science.gov (United States)

    Shen, Dan; Chen, Genshe; Pham, Khanh; Blasch, Erik

    2011-06-01

    Sensor allocation is an important and challenging problem within the field of multi-agent systems. The sensor allocation problem involves deciding how to assign a number of targets or cells to a set of agents according to some allocation protocol. Generally, in order to make efficient allocations, we need to design mechanisms that consider both the task performers' costs for the service and the associated probability of success (POS). In our problem, the costs are the used sensor resource, and the POS is the target tracking performance. Usually, POS may be perceived differently by different agents because they typically have different standards or means of evaluating the performance of their counterparts (other sensors in the search and tracking problem). Given this, we turn to the notion of trust to capture such subjective perceptions. In our approach, we develop a trust model to construct a novel mechanism that motivates sensor agents to limit their greediness or selfishness. Then we model the sensor allocation optimization problem with trust-in-loop negotiation game and solve it using a sub-game perfect equilibrium. Numerical simulations are performed to demonstrate the trust-based sensor allocation algorithm in cooperative space situation awareness (SSA) search problems.

    The potential benefits of distributed robotics systems in applications requiring situational awareness, such as search-and-rescue in emergency situations, are indisputable. The efficiency of such systems requires robotic agents capable of coping with uncertain and dynamic environmental conditions. For example, after an earthquake, a tremendous effort is spent for days to reach to surviving victims where robotic swarms or other distributed robotic systems might play a great role in achieving this faster. However, current technology falls short of offering centimeter scale mobile agents that can function effectively under such conditions. Insects, the inspiration of many robotic swarms, exhibit an unmatched ability to navigate through such environments while successfully maintaining control and stability. We have benefitted from recent developments in neural engineering and neuromuscular stimulation research to fuse the locomotory advantages of insects with the latest developments in wireless networking technologies to enable biobotic insect agents to function as search-and-rescue agents. Our research efforts towards this goal include development of biobot electronic backpack technologies, establishment of biobot tracking testbeds to evaluate locomotion control efficiency, investigation of biobotic control strategies with Gromphadorhina portentosa cockroaches and Manduca sexta moths, establishment of a localization and communication infrastructure, modeling and controlling collective motion by learning deterministic and stochastic motion models, topological motion modeling based on these models, and the development of a swarm robotic platform to be used as a testbed for our algorithms.

    Zhang, Guoxian; Ferrari, Silvia; Cai, Chenghui

    2012-02-01

    This paper investigates the comparative performance of several information-driven search strategies and decision rules using a canonical target classification problem. Five sensor models are considered: one obtained from classical estimation theory and four obtained from Bernoulli, Poisson, binomial, and mixture-of-binomial distributions. A systematic approach is presented for deriving information functions that represent the expected utility of future sensor measurements from mutual information, Rènyi divergence, Kullback-Leibler divergence, information potential, quadratic entropy, and the Cauchy-Schwarz distance. The resulting information-driven strategies are compared to direct-search, alert-confirm, task-driven (TS), and log-likelihood-ratio (LLR) search strategies. Extensive numerical simulations show that quadratic entropy typically leads to the most effective search strategy with respect to correct-classification rates. In the presence of prior information, the quadratic-entropy-driven strategy also displays the lowest rate of false alarms. However, when prior information is absent or very noisy, TS and LLR strategies achieve the lowest false-alarm rates for the Bernoulli, mixture-of-binomial, and classical sensor models.

    2008-04-01

    Finding certain associated signals in the modern electromagnetic environment can prove a difficult task due to signal characteristics and associated platform tactics as well as the systems used to find these signals. One approach to finding such signal sets is to employ multiple small unmanned aerial systems (UASs) equipped with RF sensors in a team to search an area. The search environment may be partially known, but with a significant level of uncertainty as to the locations and emissions behavior of the individual signals and their associated platforms. The team is likely to benefit from a combination of using uncertain a priori information for planning and online search algorithms for dynamic tasking of the team. Two search algorithms are examined for effectiveness: Archimedean spirals, in which the UASs comprising the team do not respond to the environment, and artificial potential fields, in which they use environmental perception and interactions to dynamically guide the search. A multi-objective genetic algorithm (MOGA) is used to explore the desirable characteristics of search algorithms for this problem using two performance objectives. The results indicate that the MOGA can successfully use uncertain a priori information to set the parameters of the search algorithms. Also, we find that artificial potential fields may result in good performance, but that each of the fields has a different contribution that may be appropriate only in certain states.

    Full Text Available Developing mobile geo-information systems for sensor web applications involves technologies that can access linked geographical and semantically related Internet information. Additionally, in tomorrow’s Web 4.0 world, it is envisioned that trillions of inexpensive micro-sensors placed throughout the environment will also become available for discovery based on their unique geo-referenced IP address. Exploring these enormous volumes of disparate heterogeneous data on today’s location and orientation aware smartphones requires context-aware smart applications and services that can deal with “information overload”. 3DQ (Three Dimensional Query is our novel mobile spatial interaction (MSI prototype that acts as a next-generation base for human interaction within such geospatial sensor web environments/urban landscapes. It filters information using “Hidden Query Removal” functionality that intelligently refines the search space by calculating the geometry of a three dimensional visibility shape (Vista space at a user’s current location. This 3D shape then becomes the query “window” in a spatial database for retrieving information on only those objects visible within a user’s actual 3D field-of-view. 3DQ reduces information overload and serves to heighten situation awareness on constrained commercial off-the-shelf devices by providing visibility space searching as a mobile web service. The effects of variations in mobile spatial search techniques in terms of query speed vs. accuracy are evaluated and presented in this paper.

    The κ-Nearest Neighbors ( κNN) query is an important spatial query in mobile sensor networks. In this work we extend κNN to include a distance constraint, calling it a l-distant κ-nearest-neighbors (l-κNN) query, which finds the κ sensor nodes nearest to a query point that are also at or greater distance from each other. The query results indicate the objects nearest to the area of interest that are scattered from each other by at least distance l. The l-κNN query can be used in most κNN applications for the case of well distributed query results. To process an l-κNN query, we must discover all sets of κNN sensor nodes and then find all pairs of sensor nodes in each set that are separated by at least a distance l. Given the limited battery and computing power of sensor nodes, this l-κNN query processing is problematically expensive in terms of energy consumption. In this paper, we propose a greedy approach for l-κNN query processing in mobile sensor networks. The key idea of the proposed approach is to divide the search space into subspaces whose all sides are l. By selecting κ sensor nodes from the other subspaces near the query point, we guarantee accurate query results for l-κNN. In our experiments, we show that the proposed method exhibits superior performance compared with a post-processing based method using the κNN query in terms of energy efficiency, query latency, and accuracy.

  9. Literature search, review, and compilation of data for chemical and radiochemical sensors: Task 1 report

    During the next several decades, the US Department of Energy is expected to spend tens of billions of dollars in the characterization, cleanup, and monitoring of DOE`s current and former installations that have various degrees of soil and groundwater contamination made up of both hazardous and mixed wastes. Each of these phases will require site surveys to determine type and quantity of hazardous and mixed wastes. It is generally recognized that these required survey and monitoring efforts cannot be performed using traditional chemistry methods based on laboratory evaluation of samples from the field. For that reason, a tremendous push during the past decade or so has been made on research and development of sensors. This report contains the results of an extensive literature search on sensors that are used or have applicability in environmental and waste management. While restricting the search to a relatively small part of the total chemistry spectrum, a sizable body of reference material is included. Results are presented in tabular form for general references obtained from data base searches, as narrative reviews of relevant chapters from proceedings, as book reviews, and as reviews of journal articles with particular relevance to the review. Four broad sensor types are covered: electrochemical processes, piezoelectric devices, fiber optics, and radiochemical processes. The topics of surface chemistry processes and biosensors are not treated separately because they often are an adjunct to one of the four sensors listed. About 1,000 tabular entries are listed, including selected journal articles, reviews of conference/meeting proceedings, and books. Literature to about mid-1992 is covered.

    The mission of an Infrared Search and Track (IRST) system is to detect and locate (sometimes called find and fix) enemy aircraft at significant ranges. Two extreme opposite examples of IRST applications are 1) long range offensive aircraft detection when electronic warfare equipment is jammed, compromised, or intentionally turned off, and 2) distributed aperture systems where enemy aircraft may be in the proximity of the host aircraft. Past IRST systems have been primarily long range offensive systems that were based on the LWIR second generation thermal imager. The new IRST systems are primarily based on staring infrared focal planes and sensors. In the same manner that FLIR92 did not work well in the design of staring infrared cameras (NVTherm was developed to address staring infrared sensor performance), current modeling techniques do not adequately describe the performance of a staring IRST sensor. There are no standard military IRST models (per AFRL and NAVAIR), and each program appears to perform their own modeling. For this reason, L-3 has decided to develop a corporate model, working with AFRL and NAVAIR, for the analysis, design, and evaluation of IRST concepts, programs, and solutions. This paper provides some of the first analyses in the L-3 IRST model development program for the optimization of staring IRST sensors.

    For the acceptance test of 26 current leads for the fusion test reactor JT-60SA in Japan the Karlsruhe Institute of Technology (KIT) constructed a current lead test system CuLTKa (Current Lead Test Facility Karlsruhe). The facility consists of a total of five cryostat and is connected with a refrigeration system. One of cryostats is used for the temperature control of a cooling flow for the experiment and contains therefore a 400 liter liquid helium container. In this there is a coiled tube located through which the helium flow (4 bar and 5.5 K) for cooling the cold contacts is cooled to bath temperature (4.5 K). During normal operation a continuous liquefaction takes place in this tank. The level is measured by a superconducting level probe and controlled by a heater via a corresponding heating load. These processes result in a permanent mixing and thus homogeneous temperature distribution throughout the container. To hedge disruption of the level probe or the heater a lower (tank empty) and an upper (tank full) cut-off point were provided. For this TVO sensors are used which act as limit switches for automatic operation of the helium cooler. This paper presents the detailed construction and the encountered obstacles in using this approach in the plant CuLTKa. It highlights the reasons and explains the followed modifications, whereby a use of TVO sensors for the said purpose has been made possible in CuLTKa. Here are holistically both the mechanical also metrological aspects described.

    Localization is an essential requirement in the increasing prevalence of wireless sensor network (WSN) applications. Reducing the computational complexity, communication overhead in WSN localization is of paramount importance in order to prolong the lifetime of the energy-limited sensor nodes and improve localization performance. This paper proposes an effective Cuckoo Search (CS) algorithm for node localization. Based on the modification of step size, this approach enables the population to approach global optimal solution rapidly, and the fitness of each solution is employed to build mutation probability for avoiding local convergence. Further, the approach restricts the population in the certain range so that it can prevent the energy consumption caused by insignificant search. Extensive experiments were conducted to study the effects of parameters like anchor density, node density and communication range on the proposed algorithm with respect to average localization error and localization success ratio. In addition, a comparative study was conducted to realize the same localization task using the same network deployment. Experimental results prove that the proposed CS algorithm can not only increase convergence rate but also reduce average localization error compared with standard CS algorithm and Particle Swarm Optimization (PSO) algorithm.

  14. Robust Modeling of Low-Cost MEMS Sensor Errors in Mobile Devices Using Fast Orthogonal Search

    Full Text Available Accessibility to inertial navigation systems (INS has been severely limited by cost in the past. The introduction of low-cost microelectromechanical system-based INS to be integrated with GPS in order to provide a reliable positioning solution has provided more wide spread use in mobile devices. The random errors of the MEMS inertial sensors may deteriorate the overall system accuracy in mobile devices. These errors are modeled stochastically and are included in the error model of the estimated techniques used such as Kalman filter or Particle filter. First-order Gauss-Markov model is usually used to describe the stochastic nature of these errors. However, if the autocorrelation sequences of these random components are examined, it can be determined that first-order Gauss-Markov model is not adequate to describe such stochastic behavior. A robust modeling technique based on fast orthogonal search is introduced to remove MEMS-based inertial sensor errors inside mobile devices that are used for several location-based services. The proposed method is applied to MEMS-based gyroscopes and accelerometers. Results show that the proposed method models low-cost MEMS sensors errors with no need for denoising techniques and using smaller model order and less computation, outperforming traditional methods by two orders of magnitude.

    Solar cells have low efficiency and non-linear characteristics. To increase the output power solar cells are connected in more complex structures. Solar panels consist of series of connected solar cells with a few bypass diodes, to avoid negative effects of partial shading conditions. Solar panels are connected to special device named the maximum power point tracker. This device adapt output power from solar panels to load requirements and have also build in a special algorithm to track the maximum power point of solar panels. Bypass diodes may cause appearance of local maxima on power-voltage curve when the panel surface is illuminated irregularly. In this case traditional maximum power point tracking algorithms can find only a local maximum power point. In this article the hybrid maximum power point search algorithm is presented. The main goal of the proposed method is a combination of two algorithms: a method that use temperature sensors to track maximum power point in partial shading conditions and a method that use illumination sensor to track maximum power point in equal illumination conditions. In comparison to another methods, the proposed algorithm uses correlation functions to determinate the relationship between values of illumination and temperature sensors and the corresponding values of current and voltage in maximum power point. In partial shading condition the algorithm calculates local maximum power points bases on the value of temperature and the correlation function and after that measures the value of power on each of calculated point choose those with have biggest value, and on its base run the perturb and observe search algorithm. In case of equal illumination algorithm calculate the maximum power point bases on the illumination value and the correlation function and on its base run the perturb and observe algorithm. In addition, the proposed method uses a special coefficient modification of correlation functions algorithm. This sub

    The Atacama B-mode Search (ABS) experiment is a 145 GHz polarimeter designed to measure the B-mode polarization of the Cosmic Microwave Background (CMB) at large angular scales. The ABS instrument will ship to the Atacama Desert of Chile fully tested and ready to observe in 2010. ABS will image large-angular-scale CMB polarization anisotropies onto a focal plane of 240 feedhorn-coupled, transition-edge sensor (TES) polarimeters, using a cryogenic crossed-Dragone design. The ABS detectors, which are fabricated at NIST, use orthomode transducers to couple orthogonal polarizations of incoming radiation onto separate TES bolometers. The incoming radiation is modulated by an ambient-temperature half-wave plate in front of the vacuum window at an aperture stop. Preliminary detector characterization indicates that the ABS detectors can achieve a sensitivity of 300 $\\mu K \\sqrt{s}$ in the field. This paper describes the ABS optical design and detector readout scheme, including feedhorn design and performance, magneti...

    The IMSAS is working on an actively heated Si substrate with interdigital structures fo working temperatures up to 550 C and for aggressive working media. The following tasks were achieved: Gas sensor design; Process development and optimisation; Processing of the Si substrate; Optimisation of the sensor substrate. The following problems were encountered: Minimisation of intrinsic stress of the stratified packages; Optimisation of the adhesive strength; Development of a stable sensor heating up to 550 C; Development and optimisation of structuring methods; Combination of thin film and thick film technologies. Resistive gas sensors with titanium-tungsten mixed oxides must be heated to 500 C for fast and sensitive response to a NO atmosphere. The gas sensitivity is strongly temperature-dependent, i.e. gas sensor temperature contro is required. In the case of diesel engine catalytic converters, ambient temperatures are high and vary with the mode of operation and operating time. The sensor temperature must be at least as high as the maximum ambient temperature and must be kept stable at this level. (orig.)

    Full Text Available Energy issue is one of the most important problems in wireless sensor networks. They consist of low-power sensor nodes and a few base station nodes. They must be adaptive and efficient in data transmission to sink in various areas. This paper proposes an aware-routing protocol based on clustering and recursive search approaches. The paper focuses on the energy efficiency issue with various measures such as prolonging network lifetime along with reducing energy consumption in the sensor nodes and increasing the system reliability. Our proposed protocol consists of two phases. In the first phase (network development phase, the sensors are placed into virtual layers. The second phase (data transmission is related to routes discovery and data transferring so it is based on virtual-based Classic-RBFS algorithm in the lake of energy problem environments but, in the nonchargeable environments, all nodes in each layer can be modeled as a random graph and then begin to be managed by the duty cycle method. Additionally, the protocol uses new topology control, data aggregation, and sleep/wake-up schemas for energy saving in the network. The simulation results show that the proposed protocol is optimal in the network lifetime and packet delivery parameters according to the present protocols.

    A new type of ceramic oxygen sensors based on semiconducting oxides was developed in this project. The advantage of these sensors compared to standard ZrO{sub 2} sensors is that they do not require a reference gas and that they can be produced in small sizes. The sensor design and the techniques developed for production of these sensors are judged suitable by the participating industry for a niche production of a new generation of oxygen sensors. Materials research on new oxygen ion conducting conductors both for applications in oxygen sensors and in fuel was also performed in this project and finally a new process was developed for fabrication of ceramic tubes by dip-coating.

    Full Text Available This paper presents a searching control approach for cooperating mobile sensor networks. We use a density function to represent the frequency of distress signals issued by victims. The mobile nodes’ moving in mission space is similar to the behaviors of fish-swarm in water. So, we take the mobile node as artificial fish node and define its operations by a probabilistic model over a limited range. A fish-swarm based algorithm is designed requiring local information at each fish node and maximizing the joint detection probabilities of distress signals. Optimization of formation is also considered for the searching control approach and is optimized by fish-swarm algorithm. Simulation results include two schemes: preset route and random walks, and it is showed that the control scheme has adaptive and effective properties.

    2012-01-01

    Search and Classification Using Multiple Autonomous Vehicles provides a comprehensive study of decision-making strategies for domain search and object classification using multiple autonomous vehicles (MAV) under both deterministic and probabilistic frameworks. It serves as a first discussion of the problem of effective resource allocation using MAV with sensing limitations, i.e., for search and classification missions over large-scale domains, or when there are far more objects to be found and classified than there are autonomous vehicles available. Under such scenarios, search and classification compete for limited sensing resources. This is because search requires vehicle mobility while classification restricts the vehicles to the vicinity of any objects found. The authors develop decision-making strategies to choose between these competing tasks and vehicle-motion-control laws to achieve the proposed management scheme. Deterministic Lyapunov-based, probabilistic Bayesian-based, and risk-based decision-mak...

  5. Gesture Recognition from Data Streams of Human Motion Sensor Using Accelerated PSO Swarm Search Feature Selection Algorithm

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available Human motion sensing technology gains tremendous popularity nowadays with practical applications such as video surveillance for security, hand signing, and smart-home and gaming. These applications capture human motions in real-time from video sensors, the data patterns are nonstationary and ever changing. While the hardware technology of such motion sensing devices as well as their data collection process become relatively mature, the computational challenge lies in the real-time analysis of these live feeds. In this paper we argue that traditional data mining methods run short of accurately analyzing the human activity patterns from the sensor data stream. The shortcoming is due to the algorithmic design which is not adaptive to the dynamic changes in the dynamic gesture motions. The successor of these algorithms which is known as data stream mining is evaluated versus traditional data mining, through a case of gesture recognition over motion data by using Microsoft Kinect sensors. Three different subjects were asked to read three comic strips and to tell the stories in front of the sensor. The data stream contains coordinates of articulation points and various positions of the parts of the human body corresponding to the actions that the user performs. In particular, a novel technique of feature selection using swarm search and accelerated PSO is proposed for enabling fast preprocessing for inducing an improved classification model in real-time. Superior result is shown in the experiment that runs on this empirical data stream. The contribution of this paper is on a comparative study between using traditional and data stream mining algorithms and incorporation of the novel improved feature selection technique with a scenario where different gesture patterns are to be recognized from streaming sensor data.

    Characteristics of conductometric enzyme glucosensor based on thin-film interdigitated electrodes have been studied. The obtained biosensor exhibits a linear dynamic range of 0.01-2 mM for glucose and sensitivity 5 microS/min*mM for kinetic mode of measurements and 8 microS/mM for steady-state mode of measurements. Additional 2% PVB- and NAFION-membranes are suggested for the extension of the dynamic range. This permits extending the dynamic range of the sensor up to glicose concentration of 10 mM. Dependence of activity of immobilized enzyme on ionic strength and buffer capacity of the solution has been studied. It was shown that formation of additional membranes results in the substantial reduction of the buffer concentration effect on the sensor response. The obtained results are interpreted in terms of permselective properties of the additional membrane formed.

The low cost ensures deployment of large sensor arrays to perform military and civilian tasks. Generally, WSNs are power constrained due to their unique deployment method which makes replacement of battery source difficult. Challenges in WSN include a well-organized communication platform for the network with negligible power utilization. In this work, an improved binary particle swarm optimization (PSO algorithm with modified connected dominating set (CDS based on residual energy is proposed for discovery of optimal number of clusters and cluster head (CH.

    For further reduction of fuel consumption of Gasoline engines the High Pressure Direct Injection is the most suitable way. For the exhaust gas aftertreatment NOx storage catalysts are used, which stores the NOx emission in lean burn phases and reduce it in short phases with rich mixture. To trigger the start of the regeneration phases suitable models can be used. The optimum start of the regeneration phase concerning emission and consumption is only possible with the use of a NOx-Sensor, so that further stringent emission regulation and OBD II requirements will force the use of the NOx-Sensor. Siemens Automotive in cooperation with NGK Insulators are developping in cooperation the 'Smart' NOx-Sensor, which can be integrated in the ECU. With this configuration all requirements concerning emission, fuel consumption and diagnosis can be fulfilled. (orig.)

The convergence of different access networks is possible via IP Multimedia Subsystem (IMS) for development toward Next Generation Networks (NGNs......) and supporting always on services. Therefore, not only Quality of Service (QoS) but also resilience is required. In this paper, we attempt to evaluate and analyze end-to-end reliability of the IMS system using a model proposed as a combination of Reliability Block Diagram (RBD) and Markov Reward Models (MRMs......). The resilience of the IMS architecture is studied by applying 1:1 redundancy at different communication scenarios between end users within and across communication domains. The model analysis provides useful reliability characteristics of the system and can be further applied for system design processes....

    Full Text Available Leptin ist ein in Adipozyten exprimiertes Hormon mit vielfältigen Funktionen im gesamten Organismus. Verschiedene Studien legen eine positive Wirkung von Leptin auf den Knochenstoffwechsel nahe. In vitro führte die Inkubation von Knochenmarkstromazellen mit Leptin zu deren Differenzierung zu Osteoblasten und Mineralisation der Matrix. Bei ovarektomierten Ratten konnte durch Leptin der Knochenverlust vermindert werden. Überraschenderweise zeigten andere Studien eine zentrale inhibitorische Wirkung von Leptin auf Osteoblasten bei Nagern. Diese einander scheinbar widersprechenden Ergebnisse zeigen, daß die molekularen Mechanismen, mit welchen Leptin auf den Knochenstoffwechsel wirkt, noch nicht ausreichend verstanden werden. In klinischen Studien findet sich eine protektive Wirkung von Fettmasse und "body mass index" (BMI auf die Knochendichte (postmenopausaler Frauen überwiegend bestätigt. Damit im Einklang, konnten erhöhte Leptinspiegel gefunden werden. Ob Leptin nun direkt in den Knochenstoffwechsel eingreift oder bloß indirekt etwa über eine erhöhte mechanische Belastung, läßt sich aus klinischen Studien allein nicht beantworten. Hingegen dürfte Leptin im Knochenstoffwechsel von Männern keine oder nur eine untergeordnete Rolle spielen. Die Situation bei Kindern und Jugendlichen ist noch unklar, wobei eine positive Wirkung von Leptin in fetalem Knochen relativ sicher ist. Leptin könnte jedoch auch im Wachstum und der Knochenreifung bei Kindern und Jugendlichen eine Rolle spielen.

    distance) and "sufficiently close" signifies lying at a distance less than a specified threshold value. It must be emphasized that although the IMS is intended to detect off-nominal or abnormal performance or health, it is not necessarily capable of performing a thorough or detailed diagnosis. Limited diagnostic information may be available under some circumstances. For example, the distance of a vector of incoming sensor data from the nearest cluster could serve as an indication of the severity of a malfunction. The identity of the nearest cluster may be a clue as to the identity of the malfunctioning component or subsystem. It is possible to decrease the IMS computation time by use of a combination of cluster-indexing and -retrieval methods. For example, in one method, the distances between each cluster and two or more reference vectors can be used for the purpose of indexing and retrieval. The clusters are sorted into a list according to these distance values, typically in ascending order of distance. When a set of input data arrives and is to be tested, the data are first arranged as an ordered set (that is, a vector). The distances from the input vector to the reference points are computed. The search of clusters from the list can then be limited to those clusters lying within a certain distance range from the input vector; the computation time is reduced by not searching the clusters at a greater distance.

    Full Text Available For predicting the key technology indicators (concentrate grade and tailings recovery rate of flotation process, a feed-forward neural network (FNN based soft-sensor model optimized by the hybrid algorithm combining particle swarm optimization (PSO algorithm and gravitational search algorithm (GSA is proposed. Although GSA has better optimization capability, it has slow convergence velocity and is easy to fall into local optimum. So in this paper, the velocity vector and position vector of GSA are adjusted by PSO algorithm in order to improve its convergence speed and prediction accuracy. Finally, the proposed hybrid algorithm is adopted to optimize the parameters of FNN soft-sensor model. Simulation results show that the model has better generalization and prediction accuracy for the concentrate grade and tailings recovery rate to meet the online soft-sensor requirements of the real-time control in the flotation process.

    Turbulence Heating ObserveR (THOR) is the first mission ever flown in space dedicated to plasma turbulence. Specifically, THOR will study how turbulent fluctuations at kinetic scales heat and accelerate particles in different turbulent environments within the near-Earth space. To achieve this goal, THOR payload is being designed to measure electromagnetic fields and particle distribution functions with unprecedented resolution and accuracy. Here we present the Ion Mass Spectrometer (IMS) instrument that will measure the full three-dimensional distribution functions of near-Earth main ion species (H+, He+, He++ and O+) at high time resolution (~ 150 ms for H+ , ~ 300 ms for He++) with energy resolution down to ~ 10% in the range 10 eV/q to 30 keV/q and angular resolution ~ 10°. Such high time resolution is achieved by mounting multiple sensors around the spacecraft body, in similar fashion to the MMS/FPI instrument. Each sensor combines a top-hat electrostatic analyzer with deflectors at the entrance together with a time-of-flight section to perform mass selection. IMS electronics includes a fast sweeping high voltage board that is required to make measurements at high cadence. Ion detection includes Micro Channel Plates (MCP) combined with Application-Specific Integrated Circuits (ASICs) for charge amplification, discrimination and time-to-digital conversion (TDC). IMS is being designed to address many of THOR science requirements, in particular ion heating and acceleration by turbulent fluctuations in foreshock, shock and magnetosheath regions. The IMS instrument is being designed and will be built by an international consortium of scientific institutes with main hardware contributions from France, USA, Japan and Germany.

    The ammonia synthesis reactor is the core unit in the whole ammonia synthesis production. The ammo- nia concentration at the ammonia converter outlet is a significant process variable, which reflects directly the pro- duction efficiency. However, it is hard to be measured reliably online in real applications. In this paper, a soft sensor based on BP neural network (BPNN) is applied to estimate the ammonia concentration. A modified group search optimization with nearest neighborhood (GSO-NH) is proposed to optimize the weights and thresholds of BPNN. GSO-NH is integrated with BPNN to build a soft sensor model. Finally, the soft sensor model based on BPNN and GSO-NH (GSO-NH-NN) is used to infer the outlet ammonia concentration in a real-world application. Three other modeling methods are applied for comparison with GSO-NH-NN. The results show that the soft sensor based on GSO-NH-NN has a good prediction performance with high accuracy. Moreover, the GSO-NH-NN also provides good generalization ability to other modeling problems in ammonia synthesis production.

    This report examines the market potential of a miniature, hand-held Ion Mobility Spectrometer. Military and civilian markets are discussed, as well as applications in a variety of diverse fields. The strengths and weaknesses of competing technologies are discussed. An extensive Ion Mobility Spectrometry (IMS) bibliography is included. The conclusions drawn from this study are: (1) There are a number of competing technologies that are capable of detecting explosives, drugs, biological, or chemical agents. The IMS system currently represents the best available compromise regarding sensitivity, specificity, and portability. (2) The military market is not as large as the commercial market, but the military services are more likely to invest R and D funds in the system. (3) Military applications should be addressed before commercial applications are addressed. (4) There is potentially a large commercial market for rugged, hand-held Ion Mobility Spectrometer systems. Commercial users typically do not invest R and D funds in this type of equipment rather, they wait for off-the-shelf availability.

    In den stark automatisierten, arbeitsteiligen Wirtschaftsystemen der Industrienationen ist die eine effiziente und zuverlässige zentrale Informationstechnik (IT) der Unternehmen entscheidend für den Geschäftserfolg. Immer mehr Unternehmensabläufe werden durch die IT unterstützt. Vielfach ist es sogar nur noch durch die umfassende IT-Unterstützung der Geschäftsprozesse möglich, im globalen Wettbewerb erfolgreich zu sein. Die installierte Rechenleistung in modernen Unternehmen steigt dabei ständig an. Neue und verbesserte Anwendungen und Programm-Features erfordern leistungsfähige Server. In den Rechenzentren kleiner und mittlerer Unternehmen sind heute Rechenleistungen installiert, die vor wenigen Jahren ausschließlich einigen Großunternehmen vorbehalten waren. Diese im Grundsatz positive Entwicklung kann aber auch zu hohen Strom- und Kühlleistungen in Rechenzentren führen.

Es ist demnach alles andere als leicht, mit solchen Forschungen zuverlässige Ergebnisse zu erzielen.

    The Provisional Technical Secretariat (PTS) of the Comprehensive Nuclear-Test-Ban Treaty (CTBTO) has a continuous interest in enhancing its capability in acoustic source detection, localization and characterization. The infrasound component of the International Monitoring System (IMS) constitutes the only worldwide ground-based infrasound network. It consists of sixty stations, among which forty-eight are already certified and continuously transmit data to the International Data Centre (IDC) in Vienna, Austria. Each infrasound station is composed of an array of infrasound sensors capable of measuring micro-pressure changes produced at ground level by infrasonic waves. The characteristics of infrasonic waves are computed in near real-time by IDC automatic detection software and are used as an input to IDC source categorization and localization algorithms. The PTS is continuously working towards the completion and sustainment of the IMS infrasound network. The objective of this presentation is to review the main activities performed in the IMS infrasound network over the last five years. This includes construction, installation, certification, major upgrade and revalidation activities. Major technology development projects to improve the reliability and robustness of IMS infrasound stations as well as their compliance with IMS Operational Manual requirements will also be presented. This includes advances in array geometry, wind noise reduction, system calibration, meteorological data as well as power and communication infrastructures. Finally the impact of all these changes on the overall detection capability of the IMS infrasound network will be highlighted.

    The effective control of pollutants in ambient air requires their fast in situ identification and concentration determination of chemical compounds in the range of micrograms per m{sup 3}. There are attempts to use conventional analytical techniques as portable GC and GC-MS. These systems are relatively expensive. A new supersensitive ion Mobility Sensor (IMS) was developed and checked by IUT Ltd, which meets the new demands. The use of tritium sources is an advantage in comparison with other IMS being equipped by nickel-63, the application of which is rather critical in respect of the radiation protection. On the other hand an integrated separation column allows to reduce interferences by matrix effects. The technical parameters of the IUT GC- IMS and some of its most important applications are briefly presented 6 refs., 1 tab., 5 figs.

  17. Maximum power point search method for photovoltaic panels which uses a light sensor in the conditions of real shading and temperature

    Science.gov (United States)

    Mroczka, Janusz; Ostrowski, Mariusz

    2015-06-01

    Disadvantages of photovoltaic panels are their low efficiency and non-linear current-voltage characteristic. Therefore it is necessary to apply the maximum power tracking systems which are dependent on the sun exposure and temperature. Trackers, that are used in photovoltaic systems, differ from each other in the speed and accuracy of tracking. Typically, in order to determine the maximum power point, trackers use measure of current and voltage. The perturb and observe algorithm or the incremental conductance method are frequent in the literature. The drawback of these solutions is the need to search the entire current-voltage curve, resulting in a significant loss of power in the fast-changing lighting conditions. Modern solutions use an additional measurement of temperature, short-circuit current or open circuit voltage in order to determine the starting point of one of the above methods, what decreases the tracking time. For this paper, a sequence of simulations and tests in real shading and temperature conditions for the investigated method, which uses additional light sensor to increase the speed of the perturb and observe algorithm in fast-changing illumination conditions was performed. Due to the non-linearity of the light sensor and the photovoltaic panel and the influence of temperature on the used sensor and panel characteristics, we cannot directly determine the relationship between them. For this reason, the tested method is divided into two steps. In the first step algorithm uses the correlation curve of the light sensor and current at the maximum power point and determines the current starting point with respect of which the perturb and observe algorithm is run. When the maximum power point is reached, in a second step, the difference between the starting point and the actual maximum power point is calculated and on this basis the coefficients of correlation curve are modified.

    2007-01-01

    The term "Smart Sensors" refers to sensors which contain both sensing and signal processing capabilities with objectives ranging from simple viewing to sophisticated remote sensing, surveillance, search/track, weapon guidance, robotics, perceptronics and intelligence applications. Recently this approach is achieving higher goals by a new and revolutionary sensors concept which introduced inside the sensor some of the basic functions of living eyes, such as dynamic stare, non-uniformity compensation, spatial and temporal filtering. New objectives and requirements are presented for this type of new infrared smart sensor systems. This paper is concerned with the front end of FPA microbolometers processing, namely, the enhancement of target-to-noise ratio by background clutter suppression and the improvement in target detection by "smart" and pattern correlation thresholding.

In many cases, the meta-information which is described consists of the classification of a resource in relation to a taxonomy or thesaurus. Agrega is a network of learning object repositories in which an LOM profile, called LOM-ES, has been used to label the objects. Part of the meta-information described corresponds to the classification of the object with respect to a group of taxonomies and a thesaurus, which have had to be described using the ims vdex standard to enable them to be managed from the federation nodes. This article describes the way in which ims vdex has been used in order to create this description and how these metadata instances are managed.

Als Ursachen für die Modifikationen im Wortschatz und im Sprachbau kann man veränderte historische, kulturelle und kommunikationstechnische Bedingungen, Globalisierungs- und Internationalisierungstendenzen, den Einfluss des Englischen sowie die Verwendung der Sprache in neuen Medien nennen. Durch ihre Verwendung im Internet kommen Sprachen zu einer neuen Form, bestimmte Sprachmuster werden besonders aktiv. Im vorliegenden Beitrag werden zwei Wortbildungsmuster, die in der deutschen Mediensprache der Gegenwart sehr zahlreich vertreten sind, behandelt, und zwar Bindestrichkomposita von Typ XL-Welle, Roggen-Vollkornbrot, das Von-der-Hand-in-den-Mund-Leben etc. und die Konfixkomposita von Typ Bio-Apfel, Bio-Baby-Lebensmittel, Euro-Bürokraten etc. Einige Gebrauchstendenzen von solchen neuartigen Komposita werden vorgestellt und unter interkulturellem Aspekt mit den neuen Erscheinungen in der litauischen Mediensprache verglichen. On New Compounds in German and Lithuanian Languages In the present article, the usage patterns of compound neologisms and occasional compounds in German and Lithuanian media languages of the press and new medium are analysed and compared in terms of intercultural aspects.

Furthermore, they experience processes of globalization and internationalization. The discourse of the press and new medium is the most instant reflection of political, economical, social and cultural changes in public life. It is rich with neologisms and occasional compounds.

    Research into environmental factors and how they affect the health of children needs to address a number of questions: Does the environment play any part in this at all? What are the affecting environmental factors? What is the scope of specific environmental factors relative to an induction or an enhancement of a disease? The search for and identification of allergens has priority relative to allergic developments in children. The author describes major allergen sources, the pathogenesis of allergies, the analysis of allergens and a study conducted by several pediatric clinics on the development of allergies in infants and young children, while focussing on risk factor of house-dust mites and options to reduce the exposure to mite-associated allergens. (Uhe) [Deutsch] Bei der Erforschung von Umweltfaktoren und ihrem Einfluss auf die Gesundheit von Kindern interessieren mehrere Fragen: spielt die Umwelt ueberhaupt ein Rolle? Welche Umwelteinfluesse sind es, wie gross ist die krankheitsindzierende oder krankheitsverstaerkte Rolle bestimmter Umwelteinfluesse? Fuef die Allergieentwicklung bei Kindern stehen die Allergene an erster Stelle. Neben der Beschreibung der wichtigsten Allergiequellen und der Entstehung von Allergien und Analytik von Allergenen wird ausfuehrlich eine Studie verschiedener Kinderkliniken zur Allergieentwicklung im Kindesalter beschrieben.

    2011-10-01

    Full Text Available OnlineberaterInnen werden regelmäßig von Ratsuchenden angefragt, ihnen in Konfliktsituationen bei der Entscheidungssuche beizustehen. Die Erleichterung über eine relativ leicht verstehbare Fragestellung kann in Ratlosigkeit umschlagen, wenn sich hinter den einfach gekleideten Entscheidungsfragen untergründige Ambivalenzen des Klienten auftun. Auch selbst bei Entscheidungsfragen vom Format des Alltags wird die Aufgabe der Beraterin nicht immer leicht. Es soll durch die 'richtigen' Fragen ein Prozess gefördert werden, dessen Richtung vom Ratsuchenden festgelegt, nicht vom Berater gesteuert wird. Es ist die Rede von Prozessen, die allgegenwärtig sind, sie werden in der Welt der Bakterien beobachtet und in Hirnprozessen des Menschen gemessen und abgebildet werden. Wie die Hilfestellung in der Sprache der schriftlichen Kommunikation via Internet aussehen kann, zeigt der Artikel an Beispielen und mit einer Liste möglicher Strategien und Methoden exemplarisch auf. Ergebnisse der Entscheidungsforschung scheinen dem Autor nur teilweise für die Beratungspraxis hilfreich zu sein. Die Kenntnis der dort entwickelten Hilfen und Einsichten wird jedoch dazu beitragen, Fehler im Beratungsprozess zu verringern. Der Artikel reflektiert die Gewichtung von rationalen und emotionalen Anteilen bei der Entscheidungssuche im Blick auf Strömungen unserer Zeit und eingegrenzt auf eine westliche Kultur.

    A combinatorial high-throughput temperature-programmed method to obtain the optimal operating temperature (OOT) of gas sensor materials is demonstrated here for the first time. A material library consisting of SnO2, ZnO, WO3, and In2O3 sensor films was fabricated by screen printing. Temperature-dependent conductivity curves were obtained by scanning this gas sensor library from 300 to 700 K in different atmospheres (dry air, formaldehyde, carbon monoxide, nitrogen dioxide, toluene and ammonia), giving the OOT of each sensor formulation as a function of the carrier and analyte gases. A comparative study of the temperature-programmed method and a conventional method showed good agreement in measured OOT.

    Full Text Available Das Waldviertel ist eine strukturschwache Region im Norden Österreichs, die eine innere Peripherie und innere Kolonie des österreichischen und europäischen Kapitalismus darstellt. Dieser Artikel analysiert die politische Ökonomie des Internets im Waldviertel. Das Waldviertel ist konfrontiert mit hohen Ausbeutungsraten im Rahmen einer imperialistischen Arbeitsteilung, Werttransfer, ungleichem Tausch, Niedriglöhnen, der Abwanderung der Textilindustrie, hoher Arbeitslosigkeit, Landflucht, dem Abbau öffentlicher Infrastruktur und Bevölkerungsrückgang. Die Analyse verdeutlicht, dass die Situation des Waldviertels als innere Peripherie der kapitalistischen Zentren die Kommunikationsverhältnisse prägt. Der Zugang zu Computern, dem Internet und Breitband ist im Waldviertel schlechter als in anderen Regionen, die Internet- und Mobiltelefonverbindungsgeschwindigkeit ist tendenziell langsamer und die Region ist eher unattraktiv für WissensarbeiterInnen. Es gibt im Waldviertel auch Ansätze einer Alternativökonomie, die den Imperialismus infrage stellen. Im Bereich der Informationsökonomie bestehen Potenziale für die Gründung von sozialistischen Kooperativen im Bereich Hardware, Software und soziale Medien, die die kapitalistische Informationsgesellschaft infrage stellen und für Alternativen kämpfen.

Ausgangspunkt war die These, dass die geographische Entfernung Kolumbiens zu Deutschland und die damit einhergehenden fehlenden Möglichkeiten der Lernenden, ihr im Unterricht erworbenes Wissen zu kontextualisieren, sich erschwerend auf die Entwicklung interkultureller Kompetenzen auswirkt. Mit dem Ziel, diese Schwierigkeit zu kompensieren, wurden zunächst die spezifischen Bedürfnisse der Lernenden ermittelt und verschiedene Lehrbücher hinsichtlich ihrer Angebote auf diese Bedürfnisse evaluiert. Schließlich wird gezeigt, wie die Ergebnisse in die Unterrichtspraxis implementiert wurden.   This article present s the results of an Action Research study carried out between 2010 and 2012 at the Colombian Universidad de los Andes. Its starting point was the hypothesis that the geographical distance between Colombia and Germany makes it more difficult for the students to contextualize the knowledge acquired in class, therefore impeding the development of intercultural competences. In order to compensate for this lack of contextualization the investigators first established the students´ specific needs. Then they evaluated different textbooks with regard to what they are offering to respond to those needs. Finally, the article describes how the findings were implemented in the classroom.

The term MHT has been used to cover therapies including estrogens, progestogens and combined regimens. For the first time, the 2016 IMS recommendations now include grades of recommendations, levels of evidence and 'good practice points', in addition to section-specific references. Where possible, the recommendations are based on and linked to the evidence that supports them, unless good-quality evidence is absent. Particular attention has been paid to published evidence from 2013 onwards, the last time the IMS recommendations were updated. Databases have been extensively searched for relevant publications using key terms specific to each specialist area within menopause physiology and medicine. Information has also been drawn from international consensus statements published by bodies such as the IMS, the European Menopause and Andropause Society and the North American Menopause Society. The recommendations have been produced by experts derived mainly from the IMS, with the assistance of key collaborators where deemed advantageous. In preparing these international recommendations, experts have taken into account geographical variations in medical care, prevalence of diseases, and country-specific attitudes of the public, medical community and health authorities towards menopause management. The variation in availability and licensing of MHT and other products has also been considered.

    dominated by pickup ions with 100-1000 eV temperatures and excursions to a “classical” cold ionosphere for the INMS is expected to be infrequent. As per the Particle Plasma Instrument (PPI) design for the strawman science payload of JEO, optimum science data return is assured when IMS is operated in conjunction with plasma electron and energetic ion sensors. The spatially and temporally varying orbital radiation environment of Europa also requires continuous monitoring of penetrating radiation fluxes to support PPI and other instrumental measurements.

  4. Searching iron sensors in plants by exploring the link among 2’-OG-dependent dioxygenases, the iron deficiency response and metabolic adjustments occurring under iron deficiency

    Full Text Available Knowledge accumulated on the regulation of iron (Fe homeostasis, its intracellular trafficking and transport across various cellular compartments and organs in plants; storage proteins, transporters and transcription factors involved in Fe metabolism have been analysed in detail in recent years. However, the key sensor(s of cellular plant Fe status triggering the long-distance shoot-root signalling and leading to the root Fe-deficiency responses is (are still unknown. Local Fe sensing is also a major task for roots, for adjusting the internal Fe requirements to external Fe availability: how such sensing is achieved and how it leads to metabolic adjustments in case of nutrient shortage, is mostly unknown. Two proteins belonging to the 2′-OG dependent dioxygenases family accumulate several folds in Fe-deficient Arabidopsis roots. Such proteins require Fe(II as enzymatic cofactor; one of their subgroups, the HIF-P4H (Hypoxia Inducible Factor- Prolyl 4-Hydroxylase, is an effective oxygen sensor in animal cells. We envisage here the possibility that some members of the 2′-OG dioxygenase family may be involved in the Fe-deficiency response and in the metabolic adjustments to Fe deficiency or even in sensing Fe, in plant cells.

  20. IMS-MS and IMS-IMS investigation of the structure and stability of dimethylamine-sulfuric acid nanoclusters.

    2015-03-12

    Recent studies of new particle formation events in the atmosphere suggest that nanoclusters (i.e, the species formed during the early stages of particle growth which are composed of 10(1)-10(3) molecules) may consist of amines and sulfuric acid. The physicochemical properties of sub-10 nm amine-sulfuric acid clusters are hence of interest. In this work, we measure the density, thermostability, and extent of water uptake of dimethylamine-sulfuric (DMAS) nanoclusters in the gas phase, produced via positive electrospray ionization. Specifically, we employ three systems to investigate DMAS properties: ion mobility spectrometry (IMS, with a parallel-plate differential mobility analyzer) is coupled with mass spectrometry to measure masses and collision cross sections for dimethylamine to sulfuric acid originally present in the electrospray solution. IMS-IMS thermostability studies reveal that partial pressures of DMAS nanoclusters are dependent upon the electrospray solution concentration ratio, R = [H2SO4]/[(CH3)2NH]. Extrapolating measurements, we estimate that dry DMAS nanoclusters have surface vapor pressures of order 10(-4) Pa near 300 K, with the surface vapor pressure increasing with increasing values of R through most of the probed concentration range. This suggests that nanocluster surface vapor pressures are substantially enhanced by capillarity effects (the Kelvin effect). Meanwhile, IMS-IMS water uptake measurements show clearly that DMAS nanoclusters uptake water at relative humidities beyond 10% near 300 K, and that larger clusters uptake water to a larger extent. In total, our results suggest that dry DMAS nanoclusters (in the 5-8.5 nm size range in diameter) would not be stable under ambient conditions; however, DMAS nanoclusters would likely be hydrated in the ambient (in some cases above 20% water by mass), which could serve to reduce surface vapor pressures and stabilize them from dissociation.

    2015-12-01

    In the distributed optical fiber sensing system based on Brillouin scattering, strain and temperature are the main measuring parameters which can be obtained by analyzing the Brillouin center frequency shift. The novel algorithm which combines the cuckoo search algorithm (CS) with the improved differential evolution (IDE) algorithm is proposed for the Brillouin scattering parameter estimation. The CS-IDE algorithm is compared with CS algorithm and analyzed in different situation. The results show that both the CS and CS-IDE algorithm have very good convergence. The analysis reveals that the CS-IDE algorithm can extract the scattering spectrum features with different linear weight ratio, linewidth combination and SNR. Moreover, the BOTDR temperature measuring system based on electron optical frequency shift is set up to verify the effectiveness of the CS-IDE algorithm. Experimental results show that there is a good linear relationship between the Brillouin center frequency shift and temperature changes.

    2011-04-01

    Full Text Available Convergence of technologies is important in this era to make progress in any field. The need to converge technologies arises from the concept of improvisation. This paper proposes a system architecture which is used to diagnose vehicle parameters and then relay the data via a feasible next generation network based on IMS architecture to a central server. Vehicles are to be equipped with a simple portable scan tool (PST device which will interface with the OBD-II port of the vehicle and record the diagnostic data and relay them to the server. Further if the vehicle owner wants real time remote updates of the vehicle then it can be done by using his/her cellular device. IMS architecture simplifies the process of user registration and help in achieving faster transmission speed. Lastly various secondary applications can be generated by this system as by using thissystem the vehicles are getting connected on a grid.

    Science.gov (United States)

    Advances in air pollution sensor technology have enabled the development of small and low cost systems to measure outdoor air pollution. The deployment of a large number of sensors across a small geographic area would have potential benefits to supplement traditional monitoring networks with additional geographic and temporal measurement resolution, if the data quality were sufficient. To understand the capability of emerging air sensor technology, the Community Air Sensor Network (CAIRSENSE) project deployed low cost, continuous and commercially-available air pollution sensors at a regulatory air monitoring site and as a local sensor network over a surrounding ~2 km area in Southeastern U.S. Co-location of sensors measuring oxides of nitrogen, ozone, carbon monoxide, sulfur dioxide, and particles revealed highly variable performance, both in terms of comparison to a reference monitor as well as whether multiple identical sensors reproduced the same signal. Multiple ozone, nitrogen dioxide, and carbon monoxide sensors revealed low to very high correlation with a reference monitor, with Pearson sample correlation coefficient (r) ranging from 0.39 to 0.97, -0.25 to 0.76, -0.40 to 0.82, respectively. The only sulfur dioxide sensor tested revealed no correlation (r 0.5), step-wise multiple linear regression was performed to determine if ambient temperature, relative humidity (RH), or age of the sensor in sampling days could be used in a correction algorihm to im

    2015-01-01

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

  7. Search Combinators

    2012-01-01

    The ability to model search in a constraint solver can be an essential asset for solving combinatorial problems. However, existing infrastructure for defining search heuristics is often inadequate. Either modeling capabilities are extremely limited or users are faced with a general-purpose programming language whose features are not tailored towards writing search heuristics. As a result, major improvements in performance may remain unexplored. This article introduces search combinators, a lightweight and solver-independent method that bridges the gap between a conceptually simple modeling language for search (high-level, functional and naturally compositional) and an efficient implementation (low-level, imperative and highly non-modular). By allowing the user to define application-tailored search strategies from a small set of primitives, search combinators effectively provide a rich domain-specific language (DSL) for modeling search to the user. Remarkably, this DSL comes at a low implementation cost to the...

    Non-target analysis has become an important tool in the field of water analysis since a broad variety of pollutants from different sources are released to the water cycle. For identification of compounds in such complex samples, liquid chromatography coupled to high resolution mass spectrometry are often used. The introduction of ion mobility spectrometry provides an additional separation dimension and allows determining collision cross sections (CCS) of the analytes as a further physicochemical constant supporting the identification. A CCS database with more than 500 standard substances including drug-like compounds and pesticides was used for CCS data base search in this work. A non-target analysis of a wastewater sample was initially performed with high performance liquid chromatography (HPLC) coupled to an ion mobility-quadrupole-time of flight mass spectrometer (IM-qTOF-MS). A database search including exact mass (±5 ppm) and CCS (±1 %) delivered 22 different compounds. Furthermore, the same sample was analyzed with a two-dimensional LC method, called LC+LC, developed in our group for the coupling to IM-qTOF-MS. This four dimensional separation platform revealed 53 different compounds, identified over exact mass and CCS, in the examined wastewater sample. It is demonstrated that the CCS database can also help to distinguish between isobaric structures exemplified for cyclophosphamide and ifosfamide.

    2006-03-01

    Full Text Available Gemeinsam von Künstlern und Wissenschaftlern/Philosophen erstellte Bücher sind selten und nicht immer erfolgreich. Eines der Fährnisse ist das Verhältnis zwischen bildlichen und schriftlichen Anteilen: Nicht selten wird der künstlerische Anteil zur Illustration der dominierenden Schrift. Eine Neupositionierung des Bildes im Buch ist nun der amerikanischen Künstlerin Roni Horn gelungen. Mehr als „sujet“ ihres Buches, ist die französische Philosophin Hélène Cixous gleichsam instruierende „Stimme“, die im Bild aufscheint. Horn hat dadurch zugleich – einmal mehr – das Phantasma unmittelbarer Abbildhaftigkeit des Fotos dekonstruiert und der philosophischen Position Cixous‘ durch das Bild eine Dimension hinzugefügt.Books created through a combined effort between artists and scholars occur seldom and are not always successful. A particular imbalance is found in the relationship between image and text: often the visual components serve merely to illustrate the more dominant text. The American artist Roni Horn has finally repositioned the importance of images in books. The voice of French philosopher Hélène Cixous is not merely the “sujet” of Horn’s book, but her instructive voice appears simultaneously in “image.” Horn thus both deconstructs the chimera of the photo’s ability to immediately visually depict the real and also adds a new dimension to Cixous’ philosophic position with her images.

Der Webseite liegt die Motivation zugrunde, Schülerinnen und Schüler für ein Nachdenken über globale Themen zu sensibilisieren. Ein solches Nachdenken ist immer auch eines über bildlich vermittelte Wirklichkeit. Es ist mit bildbild ein Anliegen, angesichts einer allseits konstatierten «Bilderflut» ein didaktisches Medium zu entwickeln, das einen Fundus an historischen und aktuellen Fotografien zur Verfügung stellt und diese so aufbereitet, dass sie gerade nicht hinter ihrer illustrativen Funktion verschwinden. Dadurch sollen die Bilder für ein selbständiges Lernen auf dem Weg hin zu einer visuellen Kompetenz einsetzbar gemacht werden. Der Beitrag beleuchtet die Entwicklung der Webseite vor dem Hintergrund kulturkritischer Haltungen zum Bild seit der Moderne sowie im Rahmen dessen, was seit den 1970er Jahren im pädagogischen Kontext als Visual Literacy diskutiert und gefördert wird. Dabei wird auch auf die medialen Potenziale einer Webseite für die Bildlesekompetenz von Jugendlichen eingegangen.

    Full Text Available Die Medienfront ist heute ein wichtiger Kriegsschauplatz, den viele neben Land, Wasser und Luft für gleich wichtig halten. Terroristen fühlen sich in sozialen Medien wohler als man denken könnte. Im Netz können sie die asymmetrische Kräfteverteilung überwinden, die sie in der offenen Feldschlacht unterlegen sein ließe. Terroristen machen sich das Bild zur Waffe und produzieren erst durch die Positionierung an der Medienfront Sinn in ihren Taten. Ohne ein Bekennerschreiben, ein Abschiedsvideo des Attentäters oder ein letztes Posting im sozialen Netzwerk wäre ein Bombenanschlag nichts als ein Kapitalverbrechen. Durch die terroristische Kommunikationsstrategie wird das Verbrechen erst zum terroristischen Akt. Das ist die theoretische Grundannahme dieses Aufsatzes. Ohne Medienberichterstattung könnten terroristische Organisationen nicht existieren. Durch die Entwicklung des Web 2.0 und insbesondere sozialer Medien kommen terroristische Organisationen heutzutage aber ganz ohne das Verschicken von Videotapes an Fernsehsender aus. Durch YouTube und andere Kanäle, können sie die Adressaten ihrer Botschaften direkt und ohne zwischengeschaltete Journalistinnen und Journalisten erreichen. So ist es nicht erstaunlich, dass terroristische Organisationen sich eine gewisse Expertise im Umgang mit sozialen Medien zugelegt haben. Al-Qaida hat seine eigene Medienabteilung, auch die kolumbianischen FARC arbeiten sehr professionell und welchen Einfluss der Islamische Staat im Internet ausübt ist inzwischen bereits Gegenstand einiger Reportagen und Untersuchungen geworden. Die diesem Aufsatz zugrundeliegende Arbeit hat sich mit neun verschiedenen Videos aus dem Umfeld von al-Qaida, der IRA und der FARC beschäftigt und versucht, aus dem analytischen Vergleich dieser Videos Rückschlüsse über terroristische Medienmacher und die terroristischen Organisationen selbst zu ziehen.

Compared to previous networks, IMS presents huge advantages, especially in terms of its ability to offer all types of services (voice and data. Nevertheless, with these advantages comes a whole new package of resilience (dependability & security challenge, e.g., attacks, human mistakes, large scale disasters, etc. In this paper, we provide an overview on the state of research in the field of IMS resilience. We propose a two-dimensional tree-based taxonomy of IMS resilience challenges. This taxonomy considers unique features of IMS such as the layered architecture. We also classify the existing countermeasures into eight classes. We identify the resilience objectives of these countermeasures and analyze their applicability and efficiency on challenge families.

Unabhängig davon, ob man für die Pluralbildung Regeln, Schemata oder die Wortstruktur als Erklärungsmodell benutzt, bleibt die Tatsache einer beachtlichen Zahl miteinander konkurrierender Formen zu erklären. Dies gilt schon deshalb, weil die Variation unter den Pluralformen wohl mit dazu beiträgt, dass trotz der Arbeiten von Mugdan 1977 und Köpcke 1987, 1993, der klaren Darstellung des Pluralsystems in vielen Grammatiken, z.B. Eisenberg 1986, 1989, 1998 noch immer bisweilen die Meinung besteht, die Pluralbildung im Deutschen sei arbiträr.Es soll gezeigt werden, dass das Pluralsystem des Deutschen nach Beschränkungen aufgebaut ist, die morphologischer und silbenphonologischer Natur sind und sich im Rahmen der Optimalitätstheorie (OT beschreiben lassen. Die OT nimmt an, dass Wortformen universalen Beschränkungen (Constraints unterliegen, und dass diese prinzipiell verletzbar sind. Ich werde zunächst die für die Pluralbildung relevanten Beschränkungen definieren, dann an heimischen Pluralformen und -varianten ihr Zusammenwirken zeigen und schließlich den Assimilationsprozess von Fremdwörtern mit Hilfe dieser Beschränkungen und der Beschränkungshierarchien zu erklären versuchen.

Whereas services like the OGC Web Map Service or Web Coverage Service are already well supported through catalogue services, the field of sensor networks and the according discovery mechanisms is still a challenge. The focus within this article will be on the use of existing OGC Sensor Web components for realizing a discovery solution. After discussing the requirements for a Sensor Web discovery mechanism, an approach will be presented that was developed within the EU funded project “OSIRIS”. This solution offers mechanisms to search for sensors, exploit basic semantic relationships, harvest sensor metadata and integrate sensor discovery into already existing catalogues.

    Astronomy has always been, and will continue to be, a data-based science, and astronomers nowadays are faced with increasingly massive datasets, one key problem of which is to efficiently retrieve the desired cup of data from the ocean. AQUAdexIM, an innovative spatial indexing and querying method, performs highly efficient on-the-fly queries under users' request to search for Time Series Images from existing observation data on the server side and only return the desired FITS images to users, so users no longer need to download entire datasets to their local machines, which will only become more and more impractical as the data size keeps increasing. Moreover, AQUAdexIM manages to keep a very low storage space overhead and its specially designed in-memory index structure enables it to search for Time Series Images of a given area of the sky 10 times faster than using Redis, a state-of-the-art in-memory database.

    Sensors play a key role in detecting both charged particles and photons for all three frontiers in Particle Physics. The signals from an individual sensor that can be used include ionization deposited, phonons created, or light emitted from excitations of the material. The individual sensors are then typically arrayed for detection of individual particles or groups of particles. Mounting of new, ever higher performance experiments, often depend on advances in sensors in a range of performance characteristics. These performance metrics can include position resolution for passing particles, time resolution on particles impacting the sensor, and overall rate capabilities. In addition the feasible detector area and cost frequently provides a limit to what can be built and therefore is often another area where improvements are important. Finally, radiation tolerance is becoming a requirement in a broad array of devices. We present a status report on a broad category of sensors, including challenges for the future ...

  6. Epilepsie im höheren Lebensalter

    Full Text Available Epilepsie tritt beim älteren Menschen bis zu 3-mal häufiger auf als in jüngeren Jahren. Dadurch und bedingt durch die allgemeine Zunahme des älteren Bevölkerungsanteils wird die Altersepilepsie immer bedeutender. Die ätiologischen Faktoren umfassen in erster Linie zerebrovaskuläre Ereignisse, Traumen, Tumoren oder Demenzsyndrome. Zumeist treten in diesem Alter fokale Anfälle mit oder ohne sekundäre Generalisierung auf. Die klinische Symptomatik kann jedoch sehr diskret sein und differenzialdiagnostisch Schwierigkeiten in der Abgrenzung zu kardialen Synkopen oder transienten ischämischen Ereignissen bieten. Aufgrund von altersbedingten Änderungen in der Pharmakokinetik stellt die Behandlung der Altersepilepsie besondere Ansprüche an den behandelnden Arzt. Die Wahl des geeigneten Antiepileptikums richtet sich dabei nicht nur nach der durch Studien belegten Effektivität, sondern muss auch die individuelle Gesamtsituation (Komorbidität, Komedikation in die Entscheidung mit einbeziehen. Im Vergleich zu den "älteren" Antiepileptika sind neuere Substanzen zwar meist nicht wesentlich effektiver, jedoch oft besser verträglich und sollten daher in dieser Altersgruppe verstärkt eingesetzt werden.

    2007-01-01

    Full Text Available Es gibt in der Literatur eine anhaltende kontroverse Diskussion über die Verlaufsform einer akuten Sigmadivertikulitis und deren Management bei jungen Patienten mit Divertikelerkrankung. In älteren Studien wird bei jungen Patienten mit unter 50 Jahren eine operative Sanierung im Sinne einer Sigmaresektion bereits nach dem ersten Schub empfohlen und hat sich so als grundsätzliche Operationsindikation in den Leitlinien niedergeschlagen. Jüngere Studien zeigen jedoch zum einen eine Verschiebung des Patientenalters zu einem früheren Erkrankungsbeginn. Zum anderen scheint bei Patienten mit unter 50 Jahren die Gefahr einer Divertikelperforation und die eines Rezidivs nicht mehr so hoch zu sein. Hieraus folgern viele Autoren, die Therapie der Divertikulitis vom Patientenalter unabhängig zu sehen. Jedoch konnten alle Studien, in denen die Altersgrenze bei 40 Jahren gesetzt wurde, zeigen, daß bei der jungen Patientengruppe die Sigmadivertikulitis aggressiver auftritt. Die bisher zumeist gesetzte Altersgrenze von 50 Jahren zur Unterscheidung von jungen und älteren Patienten sollte aufgrund der zunehmenden Verschiebung des Erkrankungsalters neu evaluiert werden. Des weiteren ist zu erwägen, Patienten mit einem Sigmadivertikulitisschub vor dem 40. Lebensjahr aufgrund der höheren Aggressivität und dem zu erwartenden langen Verlauf mit hoher Rezidivgefahr bereits nach diesem ersten Schub zu operieren.

    A Sensor Web formed of a number of different sensor pods. Each of the sensor pods include a clock which is synchronized with a master clock so that all of the sensor pods in the Web have a synchronized clock. The synchronization is carried out by first using a coarse synchronization which takes less power, and subsequently carrying out a fine synchronization to make a fine sync of all the pods on the Web. After the synchronization, the pods ping their neighbors to determine which pods are listening and responded, and then only listen during time slots corresponding to those pods which respond.

  13. Hail Monitor Sensor

    2009-01-01

    An inexpensive and simple hail monitor design has been developed that has a single piezoelectric ceramic disc and uses a metal plate as a sounding board. The structure is durable and able to withstand the launch environment. This design has several advantages over a multi-ceramic sensor, including reduced cost and complexity, increased durability, and improvement in impact response uniformity over the active surface. However, the most important characteristic of this design is the potential to use frequency discrimination between the spectrum created from raindrop impact and a hailstone impact. The sound of hail hitting a metal plate is distinctly different from the sound of rain hitting the same plate. This fortuitous behavior of the pyramid sensor may lead to a signal processing strategy, which is inherently more reliable than one depending on amplitude processing only. The initial concept has been im proved by forming a shallow pyramid structure so that hail is encouraged to bounce away from the sensor so as not to be counted more than once. The sloped surface also discourages water from collecting. Additionally, the final prototype version includes a mounting box for the piezo-ceramic, which is offset from the pyramid apex, thus helping to reduce non-uniform response (see Figure 2). The frequency spectra from a single raindrop impact and a single ice ball impact have been compared. The most notable feature of the frequency resonant peaks is the ratio of the 5.2 kHz to 3.1 kHz components. In the case of a raindrop, this ratio is very small. But in the case of an ice ball, the ratio is roughly one third. This frequency signature of ice balls should provide a robust method for discriminating raindrops from hailstones. Considering that hail size distributions (HSDs) and fall rates are roughly 1 percent that of rainfall, hailstone sizes range from a few tenths of a centimeter to several centimeters. There may be considerable size overlap between large rain and small

  14. Integrating identity-based cryptography in IMS service authentication

    Nowadays, the IP Multimedia Subsystem (IMS) is a promising research field. Many ongoing works related to the security and the performances of its employment are presented to the research community. Although, the security and data privacy aspects are very important in the IMS global objectives, they observe little attention so far. Secure access to multimedia services is based on SIP and HTTP digest on top of IMS architecture. The standard deploys AKA-MD5 for the terminal authentication. The third Generation Partnership Project (3GPP) provided Generic Bootstrapping Architecture (GBA) to authenticate the subscriber before accessing multimedia services over HTTP. In this paper, we propose a new IMS Service Authentication scheme using Identity Based cryptography (IBC). This new scheme will lead to better performances when there are simultaneous authentication requests using Identity-based Batch Verification.

    Beacham, James

    The Standard Model of particle physics encompasses three of the four known fundamental forces of nature, and has remarkably withstood all of the experimental tests of its predictions, a fact solidified by the discovery, in 2012, of the Higgs boson. However, it cannot be the complete picture. Many measurements have been made that hint at physics beyond the Standard Model, and the main task of the high- energy experimental physics community is to conduct searches for new physics in as many di↵erent places and regimes as possible. I present three searches for new phenomena in three di↵erent high-energy collider experiments, namely, a search for events with at least three photons in the final state, which is sensitive to an exotic decay of a Higgs boson into four photons via intermediate pseudoscalar particles, a, with ATLAS, at the Large Hadron Collider; a search for a dark photon, also known as an A0 , with APEX, at Thomas Je↵erson National Accelerator Facility; and a search for a Higgs decaying into four...

    2015-01-06

    Ion mobility spectrometry (IMS) is a fast and sensitive analytical method which operates at the atmospheric pressure. To enhance the capability of IMS for the analysis of mixtures, it is often used with preseparation techniques, such as GC or HPLC. Here, we report for the first time the coupling of the thin-layer chromatography and IMS. A variety of coupling schemes were tried that included direct electrospray from the TLC strip tip, indirect electrospray from a needle connected to the TLC strip, introducing the moving solvent into the injection port, and, the simplest way, offline introduction of scratched or cut pieces of strips into the IMS injection port. In this study a special solvent tank was designed and the TLC strip was mounted horizontally where the solvent would flow down. A very small funnel right below the TLC tip collected the solvent and transferred it to a needle via a capillary tubing. Using the TLC-ESI-IMS technique, acceptable separations were achieved for two component mixtures of morphine-papaverine and acridine-papaverine. A special injection port was designed to host the pieces cut off the TLC. The method was successfully used to identify each spot on the TLC by IMS in a few seconds.

    Transport systems of the future will be more efficient and less polluting than the current systems. Intermodal transport is an interesting alternative, i.e. truck/railway or truck/ship systems. In spite of extensive state funding, systems of this type still fail to meet the standards to make them competitive. The contribution compares monomodal and intermodal systems and attempts to defines strategies to make intermodal systems more successful. [German] Vor dem Hintergrund des in den vergangenen Jahren kontinuierlich gestiegenen Verkehrsaufkommens und den damit in engem Zusammenhang stehenden Umweltproblemen sind fuer die Zukunft leistungsfaehige Transportsysteme gefordert, die eine weiter wachsende Verkehrsnachfrage im Vergleich zu den zur Zeit im Einsatz befindlichen Systemen umweltvertraeglicher abwickeln. Eine aussichtsreiche Alternative stellt in diesem Zusammenhang der Kombinierte Verkehr (KV) als intermodale Verkehrsform von Lkw und Eisenbahn bzw. Schiff dar. Trotz einer Vielzahl in der Vergangenheit erfolgter staatlicher Foerdermassnahmen fehlt es dem KV nach wie vor in vielen Bereichen an der noetigen Wettbewerbsfaehigkeit, was sich in einem entsprechend niedrigen Marktanteil am Gueterverkehrsmarkt niederschlaegt. Im vorliegenden Beitrag wird dieser bei vordergruendiger Betrachtung zunaechst als Widerspruch anmutende Sachverhalt im Rahmen einer vergleichenden Analyse von verschiedenen monomodalen Transportsystemen und dem KV untersucht. Die dabei ermittelten Ergebnisse dienen im weiteren als Ausgangspunkt zur Diskussion von Ansaetzen, die ein modernes betriebliches Informationsmanagement im Hinblick auf eine Verbesserung der Akzeptanz des KV bietet.

  11. IM Normae: A Second T Pyx? (Abstract)

    Science.gov (United States)

    Patterson, J.; Monard, B.; Warhurst, P.; Myers, G.

    2015-12-01

    (Abstract only) T Pyx is the Galaxy's most famous recurrent nova, erupting to magnitude 6 about every 20 years. For nova hunters and variable-star observers generally, it should be quite easy to discover stars with similar properties. There are probably half a million CVs out to the distance of T Pyx, and most have an underlying structure similar to that of T Pyx: low-mass secondary, fairly massive white dwarf, short orbital period. But of these half million stars, there is no second T Pyx. The star is unique in another way: its orbital period is increasing on a timescale of 300,000 years. Like the proverbial bat out of hell. A 2002 nova eruption nominated a second star for this elite club: IM Nor, a short-orbital-period (2.5 hours) star which previously erupted in 1920. We began a program of time-series photometry to track the shallow eclipses—to test for orbital period change, the other signature of T Pyx resemblance. By 2015 we found this effect: Porb increases on a timescale of 2 million years. Thus, the two stars appear to be blowing themselves apart on a timescale of roughly a million years. This could explain why the stars are so rare: because they are rapidly self-immolating. And that could happen because the classical-nova outburst overwhelms the low-mass secondaries that live in short-period CVs—leading to unstable mass transfer which quickly evaporates the secondary. This implies that all short-Porb classical novae should be "recurrent" (erupting on a timescale of decades). Greater attention to CP Pup (1942), RW UMi (1956), GQ Mus (1983), and V Per (1887) is definitely warranted.

    Full Text Available Der männliche Hypogonadismus ist ein Zustand des Testosteronmangels, der einer Substitutionstherapie bedarf. Eine allgemein akzeptierte Definition dieses Zustandes existiert jedoch nicht; auch kann bisher nicht endgültig beantwortet werden, wie stark das Krankheitsbild mit dem zunehmendem Alter assoziiert ist und wie es in seiner Ausprägung dadurch möglicherweise modifiziert wird. Allerdings werden, ungeachtet des Alters, Serumtestosteronspiegel unter 12 nmol/l mit Begleiterscheinungen des Androgenmangels als Indikation für eine Testosteronsubstitutionstherapie betrachtet; der Ausschluß eines Prostatakarzinoms stellt hierbei eine Vorbedingung dar. Das injizierbare Testosteronenanthat erzeugt Serumspiegel, die für 2-3 Wochen über dem unteren Grenzbereich liegen. Länger wirkende Ester, die Injektionsintervalle zwischen 6 und 12 Wochen ermöglichen, sind in klinischer Entwicklung (z. B. injizierbares Testosteronundecanoat. Diese Ester sind günstig für die Substitutionstherapie bei jüngeren Männern, für ältere Patienten sind jedoch kürzer wirkende Präparate sinnvoll, da sie im Falle des Auftretens von Kontraindikationen (Prostatakarzinome oder Nebenwirkungen (Polyzythämien schneller abgesetzt werden können. Daher sollten bei älteren Männern vorzugsweise orale oder transdermale Präparate angewandt werden. Besonders letztere zeichnen sich durch eine dem physiologischen Rhythmus ähnliche Pharmakokinetik aus. Zukünftige Studien werden zeigen, ob synthetische Androgene mit geringerem prostatotropem Effekt wie 7alpha-methyl-19-Nortestosteron (MENT einen Vorteil bei der Behandlung hypogonadaler Männer bieten.

    In vielen Unternehmen werden heterogene (verschiedene) Steuerungen in einem abgestimmten Konzept kombiniert. Je nach Anwendungsfall und Rahmenbedingungen werden Kombinationen allgemein bekannter Steuerungen oder Steuerungsvarianten gemischt eingesetzt, um eine optimale Steuerung für unterschiedliche Fälle zu erreichen. Hierbei stehen neben den bekannten und weit verbreiteten Methoden, wie Material Requirements Planning (MRP) oder Kanban, auch weniger bekannte oder neue Methoden zur Auswahl, wie die Produktionssteuerung mit dezentraler, bestandsorientierter Fertigungsregelung (DBF). Kanban ist ein simples und effizientes Steuerungskonzept, das in der klassischen Form für spezifische einfache Anwendungsfälle umsetzbar ist. Hochentwickelte Steuerungsalgorithmen können helfen, komplexe Abläufe optimal abzubilden. Mit einer grundlegenden Vereinfachung der Abläufe kann allerdings in vielen Fällen ein wesentlich stärkerer und umfassender Verbesserungseffekt erzielt werden. Die wesentliche Fragestellung sollte folglich lauten: Warum ist der Ablauf nicht mit einer einfachen Steuerung wie Kanban abzubilden? Um die Vorteile des Konzepts auch in untypischen Bereichen anwenden zu können, sind jedoch verschiedene Varianten oder Kanban-ähnliche Steuerungsmethoden entstanden. Darüber hinaus sind in der Praxis hybride Steuerungen im Einsatz, welche so kombiniert werden, dass die Zusammensetzung anspruchsvolle Eigenschaftsbilder noch exakt abbildet. In der Praxis basieren die Steuerungsentscheidungen nur zu einem kleinen Teil auf den eigentlichen Steuerungsalgorithmen, wie sie uns das MRP-System zur Verfügung stellt. Moderne Steuerungswelten" schließen alle relevanten Informationsquellen in eine heterogene Entscheidungsmatrix mit ein. Letztlich zählt nicht, ob die Entscheidung auf den Informationen aus dem MRP-System oder auf Softfacts basierend getroffen wurde, sondern nur, ob die Entscheidung erfolgreich war.

  15. Seismic Search Engine: A distributed database for mining large scale seismic data

    Science.gov (United States)

    Liu, Y.; Vaidya, S.; Kuzma, H. A.

    2009-12-01

    The International Monitoring System (IMS) of the CTBTO collects terabytes worth of seismic measurements from many receiver stations situated around the earth with the goal of detecting underground nuclear testing events and distinguishing them from other benign, but more common events such as earthquakes and mine blasts. The International Data Center (IDC) processes and analyzes these measurements, as they are collected by the IMS, to summarize event detections in daily bulletins. Thereafter, the data measurements are archived into a large format database. Our proposed Seismic Search Engine (SSE) will facilitate a framework for data exploration of the seismic database as well as the development of seismic data mining algorithms. Analogous to GenBank, the annotated genetic sequence database maintained by NIH, through SSE, we intend to provide public access to seismic data and a set of processing and analysis tools, along with community-generated annotations and statistical models to help interpret the data. SSE will implement queries as user-defined functions composed from standard tools and models. Each query is compiled and executed over the database internally before reporting results back to the user. Since queries are expressed with standard tools and models, users can easily reproduce published results within this framework for peer-review and making metric comparisons. As an illustration, an example query is “what are the best receiver stations in East Asia for detecting events in the Middle East?” Evaluating this query involves listing all receiver stations in East Asia, characterizing known seismic events in that region, and constructing a profile for each receiver station to determine how effective its measurements are at predicting each event. The results of this query can be used to help prioritize how data is collected, identify defective instruments, and guide future sensor placements.

    One of the common ways to manage a smooth starting and stopping of asynchronous motors are soft-start system. For this provision is necessary to use a closed speed asynchronous electric drive of tiristor voltage regulator - induction motor (TVR-IM) type. Using real sensors significantly increases the cost of installation and also introduces a number of inconveniences in the operation of the actuator. Observer has clear advantages that are created on artificial neural network. Creating a neural network observer in program graphic programming LabVIEW will allow to evaluate the speed of rotation of the asynchronous electric.

    Bianco, Simone; Tisato, Francesco

    2012-01-01

    In this work we address the problem of optimal sensor placement for a given region and task. An important issue in designing sensor arrays is the appropriate placement of the sensors such that they achieve a predefined goal. There are many problems that could be considered in the placement of multiple sensors. In this work we focus on the four problems identified by Hörster and Lienhart. To solve these problems, we propose an algorithm based on Direct Search, which is able to approach the global optimal solution within reasonable time and memory consumption. The algorithm is experimentally evaluated and the results are presented on two real floorplans. The experimental results show that our DS algorithm is able to improve the results given by the most performing heuristic introduced in. The algorithm is then extended to work also on continuous solution spaces, and 3D problems.

  2. Instrumentale Spielformeln und Vokale Verzierungen im 16.Jahrhundert

    Göllner, Theodor

    2001-12-01

    Full Text Available In the music of the 16th century, stereotype four-note formulas are found in the instrumental as well as in the vocal idiom. Although frequently identical in appearance, their functions are very different. While indispensable in the instrumental idiom, particularly in keyboard music, where they represent the very essence of instruction in 15th-century organ treatises and fundamenta, they appear in vocal music only as additions to finished compositions or existing practices. What amounts to an absolute necessity in one case is merely an ornamental supplement in the other. In vocal music it is treated as a matter of performance carried out by a qualified soloist and limited to the musical centers of Italy. The present article raises the question as to how the genuinely instrumental and widely spread keyboard practice made its impact on the vocal ornaments of the singer, whose primary concern is the musical communication of language.

    [de] Die in der Musik des 16. Jahrhunderts im Instrumentalen wie im Vokalen vorkommenden, meist viertönigen, stereotypen Formeln sind zwar in beiden Bereichen weitgehend identisch, doch von höchst unterschiedlicher Funktion. Während sie im Instrumentalen, besonders in der Tastenmusik, unverzichtbar sind und schon im 15. Jahrhundert den Kern der Orgeltraktate und Fundamenta bilden, treten sie im Vokalen zu einer fertigen Komposition oder bestehenden Praxis hinzu. Was im einen Fall eine unbedingte Notwendigkeit ist, wird im anderen zu einem nachträglichen Ornament, das sich oft erst bei der Aufftührung einstellt, den qualifizierten Solosänger voraussetzt und auf die musikalischen Zentren Italiens konzentriert war. Der Artikel versucht zu klären, wie sich das genuin instrumentale, allgemein verbreitete Tastenspiel auf die spezielle Verzierungskunst des Sängers auswirkt, dessen primäre Aufgabe es ist, Sprache musikalisch zu vermitteln.

  3. A New IMS Based Inter-working Solution

    Science.gov (United States)

    Zhu, Zhongwen; Brunner, Richard

    With the evolution of third generation network, more and more multimedia services are developed and deployed. Any new service to be deployed in IMS network is required to inter-work with existing Internet communities or legacy terminal users in order to appreciate the end users, who are the main drivers for the service to succeed. The challenge for Inter-working between IMS (IP Multimedia Subsystem) and non-IMS network is “how to handle recipient’s address”. This is because each network has its own routable address schema. For instance, the address for Google Talk user is xmpp:xyz@google.com, which is un-routable in IMS network. Hereafter a new Inter-working (IW) solution between IMS and non-IMS network is proposed for multimedia services that include Instant Messaging, Chat, and File transfer, etc. It is an end-to-end solution built on IMS infrastructure. The Public Service Identity (PSI) defined in 3GPP standard (3rd Generation Partnership Project) is used to allow terminal clients to allocate this IW service. When sending the SIP (Session Initial Protocol) request out for multimedia services, the terminal includes the recipient’s address in the payload instead of the “Request-URI” header. In the network, the proposed solution provides the mapping rules between different networks in MM-IW (Multimedia IW). The detailed technical description and the corresponding use cases are present. The comparison with other alternatives is made. The benefits of the proposed solution are highlighted.

    Full Text Available Adoption of management systems standards is a key issue in manufacturing industry in India. Following the global trend quality and environmental issues are gaining importance. However the number of ISO 14001 certified companies are much less in India as compared to ISO 9001. The integration of ISO 14001 with ISO 9001 may help companies to sustain competitive advantage and overcome disappointments with quality standards and in turn encourage companies to adopt good environmental practices. The aim of this research is to study the implementation of integrated management standards (IMS by the manufacturing organizations in India. The different aspects of integration and benefits of IMS implementation are analyzed. This r esearch is based on empirical study carried out in Indian manufacturing firms, involving the application of a questionnaire. This questionnaire was tested on 50 manufacturing companies in India. The study reveals that focus on stakeholders; top management commitment and training are critical success factors for implementation of IMS. The main benefits of integration are discussed. The small sample size is one of the major limitations of this study. The paper informs the managers in manufacturing organizations and practitioners of management system standards especially in developing countries about IMS and will enable them to adopt IMS in future so that those organizations may not implement multiple and overlapping MSS(Management System Standards.

    Today, vibration sensors with low and medium sensitivities are in great demand. Their applications include robotics, navigation, machine vibration monitoring, isolation of precision equipment & activation of safety systems e.g. airbags in automobiles. Vibration sensors have been developed at SSPL, using silicon micromachining to sense vibrations in a system in the 30 - 200 Hz frequency band. The sensing element in the silicon vibration sensor is a seismic mass suspended by thin silicon hinges mounted on a metallized glass plate forming a parallel plate capacitor. The movement of the seismic mass along the vertical axis is monitored to sense vibrations. This is obtained by measuring the change in capacitance. The movable plate of the parallel plate capacitor is formed by a block connected to a surrounding frame by four cantilever beams located on sides or corners of the seismic mass. This element is fabricated by silicon micromachining. Several sensors in the chip sizes 1.6 cm x 1.6 cm, 1 cm x 1 cm and 0.7 cm x 0.7 cm have been fabricated. Work done on these sensors, techniques used in processing and silicon to glass bonding are presented in the paper. Performance evaluation of these sensors is also discussed.

    2012-01-01

    The purpose of this systematic review was to identify and summarize the research evidence on prevention of Musculoskeletal Disorders (MSD) within Occupational Health and Safety Management Systems (OHSMS) and Integrated Management Systems (IMS). Databases in business, management, engineering and health and safety were systematically searched and relevant publications were synthesized. The number of papers that could address the research questions was small. However, the review revealed that many of the techniques to address MSD hazards require substantial background knowledge and training. This may limit employees' involvement in the technical aspects of the risk assessment process. Also these techniques did not usually fit into techniques used by companies to address other risk factors within their management systems. This could result in MSD prevention becoming a separate issue that cannot be managed with company-wide tools. In addition, this review also suggested that there is a research gap concerning the MSD prevention within companies' management systems.

    The emergent IMS (Internet Protocol Multimedia Subsystem) technology appears to improve the current communication technologies. Its characteristics, such as Quality of Service (QoS), make it an advantageous system for innovative applications. Providing integrated services to users is one of the main reasons for the existence of IMS. Operators provide the technology as an open source, to be able to use services developed by researchers. Combining and integrating them, users will receive completely new services. Our proposal of use for IMS is the development of a telemedicine platform, designed to support not only remote biological signal monitoring, but value-added services for diagnosis and medical care, both of these working in real time.

    Decades of innovations in combinatorial problem solving have produced better and more complex algorithms. These new methods are better since they can solve larger problems and address new application domains. They are also more complex which means that they are hard to reproduce and often harder to fine-tune to the peculiarities of a given problem. This last point has created a paradox where efficient tools are out of reach of practitioners. Autonomous search (AS) represents a new research field defined to precisely address the above challenge.

Diversas imágenes de Dios han sido hechas en cada cultura, así como también en la Biblia, ya que ésta fue escrita en el contexto del Antiguo Próximo Oriente y Grecia. Este trabajo identifica las imágenes pastorales en Sumeria, Asiria, Babilonia, Egipto y Grecia, destacando similitudes y diferencias en sus usos entre estas naciones e Israel, y entre el Antiguo y Nuevo Testamento. En este análisis, se distingue el uso del término “pastor” como ocupación de otros usos del término transferidos a la divinidad, a los reyes y gobernantes, así como también se distingue del uso Mesías-Pastor de las funciones pastorales del liderazgo cristiano primitivo. El trabajo invita a imaginar a Dios con otras imágenes más relevantes para la vida y cultura latinoamericana, tales como: Dios-Acompañante, Dios-Multiculturalizador/a, Dios-Pacificador/a y Dios-Madre.

    We review the radio very long baseline interferometry (VLBI) observations of the guide star, IM Peg, and three compact extragalactic reference sources, 3C 454.3, B2250+194, and B2252+172, made in support of the NASA/Stanford gyroscope relativity mission, GP-B. The main goal of the observations was the determination of the proper motion of IM Peg relative to the distant universe. VLBI observations made between 1997 and 2005 yield a proper motion of IM Peg of -20.83 $\\pm$ 0.09 mas yr$^{-1}$ in RA and -27.27 $\\pm$ 0.09 mas yr$^{-1}$ in dec, in a celestial reference frame of extragalactic radio galaxies and quasars virtually identical to the International Celestial Reference Frame 2 (ICRF2). They also yield a parallax for IM Peg of 10.37 $\\pm$ 0.07 mas, corresponding to a distance of 96.4 $\\pm$ 0.7 pc. The uncertainties are standard errors with statistical and estimated systematic contributions added in quadrature. These results met the pre-launch requirements of the GP-B mission to not discernibly degrade the es...

    Full Text Available The development of packed based multimedia networks reached a turning point when the ITU-T and the ETSIhave incorporated the IMS to the NGN. With the fast development of mobile communication more and more services andcontent are available. In contrast with fix network telephony both the services and the devices are personalized in the “mobileworld”. Services, known from the Internet - like e-mail, chat, browsing, presence, etc. – are already available via mobiledevices as well. The IMS originally wanted to exploit both the benefits of mobile networks and the fancy services of theInternet. But today it is already more than that. IMS is the core of the next generation telecommunication networks and abasis for fix-mobile convergent services. The fact however that IMS was originally a “mobile” standard, where IPv6 was notoddity generated some problems for the fix networks, where IPv4 is used. In this article I give an overview of these problemsand mention some solutions as well.

Zahlreiche Veröffentlichungen belegen, dass FDI den Transfer von und/oder den Zugang zu Technologien erleichtert. Allerdings gibt es zu wenige empirische Studien, die diesen Zusammenhang in Bezug auf die Wirtschaft afrikanischer Staaten untersuchen. Der Autor will diese Lücke zu einem kleinen Teil schließen, indem er die Bedeutung des Technologietransfers durch den Zufluss von FDI im Energiesektor Angolas ermittelt. Seine Analyse basiert auf qualitativer Forschung in Angola im Jahr 2014.

    gas is involved in such a collision. If some of the gas from either cluster has particles of antimatter, then there will be annihilation and the X-rays will be accompanied by gamma rays. Steigman used data obtained by Chandra and Compton to study the so-called Bullet Cluster, where two large clusters of galaxies have crashed into one another at extremely high velocities. At a relatively close distance and with a favorable side-on orientation as viewed from Earth, the Bullet Cluster provides an excellent test site to search for the signal for antimatter.

Jet Power and Black Hole Assortment Revealed in New Chandra Image Chandra Data Reveal Rapidly Whirling Black Holes Black Holes Have Simple Feeding Habits Galaxies Coming of Age in Cosmic Blobs "This is the largest scale over which this test for antimatter has ever been done," said Steigman, whose paper was published in the Journal of Cosmology and Astroparticle Physics. "I'm looking to see if there could be any clusters of galaxies which are made of large amounts of antimatter." The observed amount of X-rays from Chandra and the non-detection of gamma rays from the Compton data show that the antimatter fraction in the Bullet Cluster is less than three parts per million. Moreover, simulations of the Bullet Cluster merger show that these results rule out any significant amounts of antimatter over scales of about 65 million light years, an estimate of the original separation of the two colliding clusters. "The collision of matter and antimatter is the most efficient process for generating energy in the Universe, but it just may not happen on very large scales," said Steigman. "But, I'm not giving up yet as I'm planning to look at other colliding galaxy clusters that have recently been discovered." Finding antimatter in the Universe might tell scientists about how long the period of inflation lasted. "Success in this experiment, although a long shot, would teach us a lot about the earliest

    A gas sensor is described which incorporates a sensor stack comprising a first film layer of a ferromagnetic material, a spacer layer, and a second film layer of the ferromagnetic material. The first film layer is fabricated so that it exhibits a dependence of its magnetic anisotropy direction on the presence of a gas, That is, the orientation of the easy axis of magnetization will flip from out-of-plane to in-plane when the gas to be detected is present in sufficient concentration. By monitoring the change in resistance of the sensor stack when the orientation of the first layer's magnetization changes, and correlating that change with temperature one can determine both the identity and relative concentration of the detected gas. In one embodiment the stack sensor comprises a top ferromagnetic layer two mono layers thick of cobalt deposited upon a spacer layer of ruthenium, which in turn has a second layer of cobalt disposed on its other side, this second cobalt layer in contact with a programmable heater chip.

    Disclosed is a passive, in-situ pressure sensor. The sensor includes a sensing element having a ferromagnetic metal and a tension inducing mechanism coupled to the ferromagnetic metal. The tension inducing mechanism is operable to change a tensile stress upon the ferromagnetic metal based on a change in pressure in the sensing element. Changes in pressure are detected based on changes in the magnetic switching characteristics of the ferromagnetic metal when subjected to an alternating magnetic field caused by the change in the tensile stress. The sensing element is embeddable in a closed system for detecting pressure changes without the need for any penetrations of the system for power or data acquisition by detecting changes in the magnetic switching characteristics of the ferromagnetic metal caused by the tensile stress.

    A corrosion sensor array incorporating individual elements for measuring various elements and ions, such as chloride, sulfide, copper, hydrogen (pH), etc. and elements for evaluating the instantaneous corrosion properties of structural materials. The exact combination and number of elements measured or monitored would depend upon the environmental conditions and materials used which are subject to corrosive effects. Such a corrosion monitoring system embedded in or mounted on a structure exposed to the environment would serve as an early warning system for the onset of severe corrosion problems for the structure, thus providing a safety factor as well as economic factors. The sensor array is accessed to an electronics/computational system, which provides a means for data collection and analysis.

    1996-12-31

    Coal mining in the Rhenish brown coal district resulted in loose rock slopes with a total height of more than 350 m. Mining operations caused ground motion in open-cast mines, in the slopes and in the region ahead of the face. Internal dumping caused motions of the floors, the overburden tip and te slopes of the open-cast mines. The deformations were measured by different methods, and the evaluations are presented here. As examples, permanent monitoring of a slope using the GEOROBOT measuring system and continuous subsidence measurements in an overburdan dump by means of hydrostatic measuring systems are presented. GEOROBOT ensures quasi-continuous measurements of slope motion with an error of 5-7 mm. Hydrostatic measuring systems on the basis of pressure sensors were developed for measurements of single overburden dump strata and the overburden dump basis during dumping. (orig.)

    Full Text Available In der Literatur zur qualitativen Inhaltsanalyse werden verschiedene Varianten des Verfahrens unterschieden, darunter beispielsweise die inhaltlich-strukturierende, die evaluative, die skalierende, die zusammenfassende oder die typenbildende Inhaltsanalyse. Dabei bleibt jedoch unklar, wie diese verschiedenen Varianten sich zueinander verhalten. In dem vorliegenden Beitrag werden die verschiedenen Versionen qualitativer Inhaltsanalyse beschrieben und in Beziehung gesetzt. Dabei ergeben sich zwei Basisformen qualitativer Inhaltsanalyse: die strukturierende qualitative Inhaltsanalyse und die qualitative Inhaltsanalyse durch Extraktion. Die anderen Varianten werden nicht als eigenständige Versionen rekonstruiert, sondern als Variationen im Ablauf der strukturierenden Inhaltsanalyse. Darüber hinaus sind weitere Variationen möglich und sinnvoll, die abschließend im Sinne eines "Werkzeugkastens" qualitativer Inhaltsanalyse dargestellt werden.

    2007-09-01

    Full Text Available Motivation: This paper will discuss sensitivity issues in rotor speed estimation for induction machine (IM drives using only voltage and current measurements. A supervised estimation algorithm is proposed with the aim to achieve good performances in the large variations of the speed. After a brief presentation on discrete feedback structure of the estimator formulated from d-q axis equations, we will expose its performances for machine parameters variations.Method: Hyperstability concept was applied to the synthesis adaptation low. A heuristic term is added to the algorithm to maintain good speed estimation factor in high speeds.Results: In simulation, the estimation error is maintained relatively low in wide range of speeds, and the robustness of the estimation algorithm is shown for machine parametric variations.Conclusions: Sensitivity analysis to motor parameter changes of proposed sensorless IM is then performed.

    Full Text Available Ziel des vorliegenden Beitrags ist es, deutlich zu machen, dass Mediensozialisations­forschung nicht ohne den Blick auf die Lebenswelt Heranwachsender auskommen kann; diese wird geprägt vom sozialen Milieu (einer Manifestation des je spezifischen Zusammenhangs von sozialer Lage und Lebensentwurf der agierenden Personen, in dessen Rahmen sich das Aufwachsen von Kindern und Jugendlichen vollzieht. Seine spezifischen Konstellationen, zu denen auch die Medienumgangsweisen gehören, müssen daher in die Forschung miteinbezogen werden. Um die Bedeutung, die Mediensymbolik im Alltag von Heranwachsenden einnimmt, im Kontext untersuchen zu können, erscheint eine integrative sowie interdisziplinäre Forschung notwendig. Als Beispiel dafür wird eine Panelstudie zur (Medien-Sozialisation bei sozial benachteiligten Kindern in Österreich in ihrer theoretischen und methodologischen Anlage vorgestellt.

    Hazard perception is a critical skill for road users. In this study, an open-loop motorcycle simulator was used to examine the effects of motorcycle riding and car driving experience on hazard perception and visual scanning patterns. Three groups of participants were tested: experienced motorcycle riders who were experienced drivers (EM-ED), inexperienced riders/experienced drivers (IM-ED), and inexperienced riders/inexperienced drivers (IM-ID). Participants were asked to search for hazards in simulated scenarios, and click a response button when a hazard was identified. The results revealed a significant monotonic decrease in hazard response times as experience increased from IM-ID to IM-ED to EM-ED. Compared to the IM-ID group, both the EM-ED and IM-ED groups exhibited more flexible visual scanning patterns that were sensitive to the presence of hazards. These results point to the potential benefit of training hazard perception and visual scanning in motorcycle riders, as has been successfully demonstrated in previous studies with car drivers.

    Full Text Available As the network convergence with services for both static and mobile networks has been the principal object of the next generation networks, the recent research focus is converging in the direction of standardizing common infrastructure based on all-IP networks. IMS is a recent initiative. Moreover, designing and deploying a standard QoS provisioning mechanisms in large networks is not a trivial matter. IPTV services are considered between the important IMS flow, the actual QoS management mechanisms proposed by 3GPP allow providing the IMS network components control and efficient service delivery, however the 3GPP approach focuses entirely on the step of providing the service, but there is no mechanism for monitoring Qos dynamically. This paper discusses the issues, design and analysis related to on demand dynamic QoS control in these next generation networks and fuss both Quality of Service (QoS information signaling and IPTV traffic engineering options that may serve as key components of IPTV service specific QoS policies, which are designed to accommodate with customer requirements and resource availability by using the eTOM process to monitor the Qos values and to propose optimal solution to provide the quality of delivered content. The eTOM process interact with implemented marking entities which execute an algorithm to marking IPTV packets, this cooperation must improve the quality of service of the IPTV traffic

    This version of the Impact of Sector Energy Technologies (ImSET) model represents the ''next generation'' of the previously developed Visual Basic model (ImBUILD 2.0) that was developed in 2003 to estimate the macroeconomic impacts of energy-efficient technology in buildings. More specifically, a special-purpose version of the 1997 benchmark national Input-Output (I-O) model was designed specifically to estimate the national employment and income effects of the deployment of Office of Energy Efficiency and Renewable Energy (EERE) -developed energy-saving technologies. In comparison with the previous versions of the model, this version allows for more complete and automated analysis of the essential features of energy efficiency investments in buildings, industry, transportation, and the electric power sectors. This version also incorporates improvements in the treatment of operations and maintenance costs, and improves the treatment of financing of investment options. ImSET is also easier to use than extant macroeconomic simulation models and incorporates information developed by each of the EERE offices as part of the requirements of the Government Performance and Results Act.

    Full Text Available Die Lehren Carl Schmitts haben wieder einmal Hochkonjunktur. Insbesondere sein von der Unterscheidung zwischen Freund und Feind bestimmter Begriff des Politischen und die Idee vom Ausnahmezustand, in dem das Recht der Normallage nicht gelte, sind derzeit aktuell. Die Reaktualisierung ist vor allem der Kriegsrhetorik geschuldet, die sich im Kampf gegen den internationalen Terrorismus etabliert. Schmitts Begrifflichkeit wird in Anspruch genommen, um diverse Antiterrormaßnahmen der normalen juristischen Beurteilung zu entziehen. Die durch souveräne politische Entscheidung ausgerufene Ausnahme soll die Geltung des Rechts suspendieren. Dabei droht die Ausnahme zur Regel zu werden. Der dadurch behauptete Vorrang des Politischen wird im Rahmen einer Analyse der Schriften Schmitts und der internationalen Rezeption seiner Theorien einer kritischen Prüfung unterzogen und zurückgewiesen.

    Ion-mobility spectroscopy (IMS) was evaluated as a high-throughput, cheap, and efficient analytical tool for detecting residues of tetrahydrocannabinol (THC) on hands. Regarding the usefulness of hand residues as potential samples for determining THC handling and abuse, we studied the correlation between data obtained from cannabis consumers who were classified as positive after saliva analysis and from those who were classified as positive on the basis of the information from hand-residue analysis. Sampling consisted of wiping the hands with borosilicate glass microfiber filters and introducing these directly into the IMS after thermal desorption. The possibility of false positive responses, resulting from the presence of other compounds with a similar drift time to THC, was evaluated and minimised by applying the truncated negative second-derivative algorithm. The possibility of false negative responses, mainly caused by competitive ionisation resulting from nicotine, was also studied. Graphical abstract THC residues: from hands to analytical signals.

    The Any Light Particle Search II (ALPS II) experiment (DESY, Hamburg) searches for photon oscillations into Weakly Interacting Sub-eV Particles (WISPs). This second generation of the ALPS light-shining-through-a-wall (LSW) experiment approaches the finalization of the preparation phase before ALPS IIa (search for hidden photons). In the last years, efforts have been put for the setting up of two optical cavities as well as characterization of a single-photon Transition-Edge Sensor (TES) detector. In the following, we put some emphasis on the detector development. In parallel, the setting up of ALPS IIc (search for axion-like particles), including the unbending of 20 HERA dipoles, has been pursued. The latest progress in these tasks will be discussed.

  18. Rapid and accurate detection of urinary pathogens by mobile IMS-based electronic nose: a proof-of-principle study.

    Directory of Open Access Journals (Sweden)

    Antti Roine

    Full Text Available Urinary tract infection (UTI is a common disease with significant morbidity and economic burden, accounting for a significant part of the workload in clinical microbiology laboratories. Current clinical chemisty point-of-care diagnostics rely on imperfect dipstick analysis which only provides indirect and insensitive evidence of urinary bacterial pathogens. An electronic nose (eNose is a handheld device mimicking mammalian olfaction that potentially offers affordable and rapid analysis of samples without preparation at athmospheric pressure. In this study we demonstrate the applicability of ion mobility spectrometry (IMS -based eNose to discriminate the most common UTI pathogens from gaseous headspace of culture plates rapidly and without sample preparation. We gathered a total of 101 culture samples containing four most common UTI bacteries: E. coli, S. saprophyticus, E. faecalis, Klebsiella spp and sterile culture plates. The samples were analyzed using ChemPro 100i device, consisting of IMS cell and six semiconductor sensors. Data analysis was conducted by linear discriminant analysis (LDA and logistic regression (LR. The results were validated by leave-one-out and 5-fold cross validation analysis. In discrimination of sterile and bacterial samples sensitivity of 95% and specificity of 97% were achieved. The bacterial species were identified with sensitivity of 95% and specificity of 96% using eNose as compared to urine bacterial cultures.These findings strongly demonstrate the ability of our eNose to discriminate bacterial cultures and provides a proof of principle to use this method in urinanalysis of UTI.

    Science.gov (United States)

    Thundat, T.G.; Wachter, E.A.

    1998-02-17

    An improved microcantilever sensor is fabricated with at least one microcantilever attached to a piezoelectric transducer. The microcantilever is partially surface treated with a compound selective substance having substantially exclusive affinity for a targeted compound in a monitored atmosphere. The microcantilever sensor is also provided with a frequency detection means and a bending detection means. The frequency detection means is capable of detecting changes in the resonance frequency of the vibrated microcantilever in the monitored atmosphere. The bending detection means is capable of detecting changes in the bending of the vibrated microcantilever in the monitored atmosphere coactively with the frequency detection means. The piezoelectric transducer is excited by an oscillator means which provides a signal driving the transducer at a resonance frequency inducing a predetermined order of resonance on the partially treated microcantilever. Upon insertion into a monitored atmosphere, molecules of the targeted chemical attach to the treated regions of the microcantilever resulting in a change in oscillating mass as well as a change in microcantilever spring constant thereby influencing the resonant frequency of the microcantilever oscillation. Furthermore, the molecular attachment of the target chemical to the treated regions induce areas of mechanical strain in the microcantilever consistent with the treated regions thereby influencing microcantilever bending. The rate at which the treated microcantilever accumulates the target chemical is a function of the target chemical concentration. Consequently, the extent of microcantilever oscillation frequency change and bending is related to the concentration of target chemical within the monitored atmosphere. 16 figs.

    Full Text Available As with the development of computer technology and informatization, network technique, sensor technique and communication technology become three necessary components of information industry. As the core technique of sensor application, signal processing mainly determines the sensor performances. For this reason, study on signal processing mode is very important to sensors and the application of sensor network. In this paper, we introduce a new sensor coarse signal processing mode based on adaptive genetic algorithm. This algorithm selects crossover, mutation probability adaptively and compensates multiple operators commutatively to optimize the search process, so that we can obtain the global optimum solution. Based on the proposed algorithm, using auto-correlative characteristic parameter extraction method, it achieves smaller test error in sensor coarse signal processing mode of processing interference signal. We evaluate the proposed approach on a set of data. The experimental results show that, the proposed approach is able to improve the performance in different experimental setting

  5. Sensor Placement for Sensing Coverage and Data Precision in Wireless Sensor Networks

    2008-01-01

    We present a novel paradigm of sensor placement concerning data precision and estimation. Multiple abstract sensors are used to measure a quantity of a moving target in the scenario of a wireless sensor network. These sensors can cooperate with each other to obtain a precise estimate of the quantity in a real-time manner. We consider a problem on planning a minimum-cost scheme of sensor placement with desired data precision and resource consumption. Measured data is modeled as a Gaussian random variable with a changeable variance. A gird model is used to approximate the problem. We solve the problem with a heuristic algorithm using branch-and-bound method and tabu search. Our experiments demonstrate that the algorithm is correct in a certain tolerance, and it is also efficient and scalable.

    produced at relatively low cost. Therefore, they find wide use in lots of applications. However, the method requires a material that possesses some conflicting properties: stable and reproducible relations between air humidity, moisture uptake and a specific property (for instance the length of a hair, the electrical impedance of the material), fast absorption and desorption of the water vapour (to obtain a short response time), small hysteresis, wide range of relative humidity (RH) and temperature-independent output (only responsive to RH). For these reasons, much research is done and is still going on to find suitable materials that combine high performance and low price. In this special feature, three of the four papers report on absorption sensors, all with different focus. Aziz et al describe experiments with newly developed materials. The surface structure is extensively studied, in view of its ability to rapidly absorb water vapour and exhibit a reproducible change in the resistance and capacitance of the device. Sanchez et al employ optical fibres coated with a thin moisture-absorbing layer as a sensitive humidity sensor. They have studied various coating materials and investigated the possibility of using changes in optical properties of the fibre (here the lossy mode resonance) due to a change in humidity of the surrounding air. The third paper, by Weremczuk et al, focuses on a cheap fabrication method for absorption-based humidity sensors. The inkjet technology appears to be suitable for mass fabrication of such sensors, which is demonstrated by extensive measurements of the electrical properties (resistance and capacitance) of the absorbing layers. Moreover, they have developed a model that describes the relation between humidity and the electrical parameters of the moisture-sensitive layer. Despite intensive research, absorption sensors still do not meet the requirements for high accuracy applications. The dew-point temperature method is more appropriate

    Understanding how herbicides affect plant reproduction and growth is critical to develop herbicide toxicity model and refine herbicide risk assessment. Although our knowledge of herbicides toxicity mechanisms at the physiological and molecular level in plant vegetative phase has increased substantially in the last decades, few studies have addressed the herbicide toxicity problematic on plant reproduction. Here, we determined the long-term (4-8 weeks) effect of a chiral herbicide, imazethapyr (IM), which has been increasingly used in plant crops, on floral organ development and reproduction in the model plant Arabidopsis thaliana. More specifically, we followed the effect of two IM enantiomers (R- and S-IM) on floral organ structure, seed production, pollen viability and the transcription of key genes involved in anther and pollen development. The results showed that IM strongly inhibited the transcripts of genes regulating A. thaliana tapetum development (DYT1: DYSFUNCTIONAL TAPETUM 1), tapetal differentiation and function (TDF1: TAPETAL DEVELOPMENT AND FUNCTION1), and pollen wall formation and developments (AMS: ABORTED MICROSPORES, MYB103: MYB DOMAIN PROTEIN 103, MS1: MALE STERILITY 1, MS2: MALE STERILITY 2). Since DYT1 positively regulates 33 genes involved in cell-wall modification (such as, TDF1, AMS, MYB103, MS1, MS2) that can catalyze the breakdown of polysaccharides to facilitate anther dehiscence, the consistent decrease in the transcription of these genes after IM exposure should hamper anther opening as observed under scanning electron microscopy. The toxicity of IM on anther opening further lead to a decrease in pollen production and pollen viability. Furthermore, long-term IM exposure increased the number of apurinic/apyrimidinic sites (AP sites) in the DNA of A. thaliana and also altered the DNA of A. thaliana offspring grown in IM-free soils. Toxicity of IM on floral organs development and reproduction was generally higher in the presence of the R-IM

    Conventional projection radiography (chest x-ray) is one of the most frequently requested procedures in radiology. Even though chest x-ray imaging is frequently performed in asymptomatic patients for preoperative assessment, clinically relevant incidental findings are relatively scarce. This is due to the relatively low sensitivity of chest x-rays where few clinically relevant incidental findings are to be expected, as any detectable pathologies will as a rule already be clinically symptomatic. Recommendations from relevant societies for the management of incidental findings, apart from the clarification of incidental nodules, do not exist. This review article therefore describes the most frequent and typical incidental findings of lung parenchyma (apart from pulmonary nodules), mediastinal structures including the hilum of the lungs, pleura, chest wall and major vessels. Also described are those findings which can be diagnosed with sufficient certainty from chest x-rays so that further clarification is not necessary and those which must be further clarified by multislice imaging procedures or other techniques. (orig.) [German] Eine der haeufigsten Untersuchungen in der Radiologie ist die konventionelle Projektionsradiographie des Thorax (Roentgenthorax). Auch wenn projektionsradiographische Aufnahmen im Rahmen einer praeoperativen Abklaerung haeufig als orientierende Untersuchung angefertigt werden, sind - bedingt durch die relativ geringe Sensitivitaet des Roentgenthorax - wenig klinisch relevante Zufallsbefunde zu erwarten, da nachweisbare Pathologien in der Regel bereits auch klinisch apparent sind. Empfehlungen entsprechender Fachgesellschaften zu Zufallsbefunden im Roentgenthorax jenseits der Abklaerung von Rundherden liegen nicht vor. Die vorliegende Arbeit beleuchtet daher haeufige und typische Zufallsbefunde des Lungenparenchyms (ausser den Lungenrundherden), der mediastinalen Strukturen einschliesslich der Hili, der Pleura, der Thoraxwand sowie der

    Full Text Available El objetivo de este artículo es brindar al clínico pautas para el uso racional y adecuado de los avances tecnológicos en imaginología, para de esta manera lograr un criterio multidisciplinario en el momento de tomar una decisión buscando el beneficio del paciente sin someterlo a exámenes de poca utilidad. Se realizó una búsqueda sistemática de la literatura médica acerca de la cefalea abarcando su fisiopatología, clasificación y, específicamente, el uso de imágenes diagnósticas. Para ello se hizo búsqueda en diferentes bases de datos según las palabras claves indicadas. El abordaje clínico y la diferenciación entre el tipo de cefalea es primordial para decidir el beneficio y la necesidad del uso de imágenes diagnósticas. Las neuroimágenes no son comúnmente solicitadas en pacientes con cefalea primaria, se comienza la sospecha clínica ante la presencia de señales de alarma. Las cefaleas secundarias requieren un estudio más extenso en los cuales se incluye la toma de imágenes radiológicas. Teniendo en cuenta los beneficios de la TC y la RM que se exponen en esta revisión, la TC es preferida en situaciones de urgencia, y para aquellas que no lo son, la RM es más adecuada.

  18. Towards Service Sontinuity in IMS Heterogeneous Access Networks

    Full Text Available In this paper we tackle the mobility issue in IP Multimedia Subsystem (IMS. Although IMS was designedto integrate different access networks, mobility management among these networks is still unresolved. We propose a novel hybrid mobility management scheme, based on tight cooperation between fast handovers for mobile IPv6 (FMIPv6 and session initiation protocol (SIP to ensure an uninterrupted real-time service. Moreover, the new Media Independent Handover (MIH service is integrated into IMS architecture in order to perform intelligent and accurate horizontal and vertical handovers. We investigate two handover cases: selected handover and forced handover. Selected handover takes place when user equipment (UE is connected to the network via two interfaces at the same time and decides to upgrade the quality of its connection following a given criterion (i.e. cost, bandwidth…etc without having any difficulty in the previous link. As far as forced handover is concerned, it occurs when thesignal reaches a critical level and UE is forced to make a handover in order to maintain the ongoing communication. This case is managed in two phases. The first one or the fast phase is handled by FMIPv6 protocol to preserve as soon as possible packets of the ongoing communication. The second one or the slow phase is handled by SIP protocol to optimize packet delivery route. By doing so, we exploit the benefits of both network layer and application mobility protocols to ensure a continuous session over the two networks without imposing new elements to the network. Through a comparison with other mobility mechanisms, we show in the analytic analysis that our hybrid scheme presents better results in terms of handover latency and packet loss.

    A novel electric vehicle (EV) induction motor (IM) controller based on voltage-fed inverter is presented. It is shown that the proposed adaptive control algorithm effectively both simplifies the structure and expands the capacity of controller. The relationship between stator's voltage and that of current under rotor's flux-oriented-coordinates is first introduced, and then the structure of vector control is analyzed, in which voltage compensation is inducted as the core feedback procedure. Experiments prove that, together with a facility for realization, a smooth transition, a prompt torque response and small concussion are gained. Extensive research conducted by varying parameters that result in practical ripple is proposed in conclusion.

    Objective To elucidate the inhibitory effects of recombinant Chinese scorpion neurotoxin BmK IM on seizures induced by pentylenetetrazol (PTZ) and the possible mechanism.Methods After purifying recombinant BmK IM from an E. coli cell line, its toxicity (both LD50 and minimum lethal dose) on rats was determined. BmK IM was then microinjected into the CA3 region of the right hippocampus and its ability to inhibit the effects of an intraperitoneal injection of PTZ was assessed. The effects of BmK IM on the electrophysiological properties of isolated CA3 pyramidal neurons were then studied using whole-cell patch clamp techniques.Results BmK IM can significantly prolong the latent period of epileptic seizures, decrease the degree of seizures, and decrease the frequency of epileptiform discharges induced by PTZ. At the same time, 24h after injection of BmK IM into the hippocampal tissue, BmK IM significantly reduces the concentration of the neurotransmitter glutamate and alleviates PTZ-induced lesions in the hippocampus. Whole-cell patch clamp recordings indicate that BmK IM inhibits INa of rat hippocampal neurons in a dose-dependent manner. BmK IM significantly shifts the activation curve of INa in a positive direction, indicating that BmK IM enhances the threshold potential of INa.Conclusions BmK IM has significant anti-epileptic properties, and may prove useful as a drug in the therapy of epilepsy. The inhibitory effects of BmK IM on seizures caused by pentylenetetrazol might depend on reductions in the release of presynaptic glutamate via the blocking of Na+ channels.

However, the authoring process of a UoL remains difficult because of the lack of high-level authoring tools for IMS-LD, even more so when the focus is on specific topics,…

    The Interval Management (IM) Avionics Phase 2 flight test used three aircraft over a nineteen day period to operationally evaluate a prototype IM avionics. Quantitative data were collected on aircraft state data and IM spacing algorithm performance, and qualitative data were collected through end-of-scenario and end-of-day flight crew surveys. The majority of the IM operations met the performance goals established for spacing accuracy at the Achieve-by Point and the Planned Termination Point, however there were operations that did not meet goals for a variety of reasons. While the positive spacing accuracy results demonstrate the prototype IM avionics can contribute to the overall air traffic goal, critical issues were also identified that need to be addressed to enhance IM performance. The first category was those issues that impacted the conduct and results of the flight test, but are not part of the IM concept or procedures. These included the design of arrival and approach procedures was not ideal to support speed as the primary control mechanism, the ground-side of the Air Traffic Management Technology Demonstration (ATD-1) integrated concept of operations was not part of the flight test, and the high workload to manually enter the information required to conduct an IM operation. The second category was issues associated with the IM spacing algorithm or flight crew procedures. These issues include the high frequency of IM speed changes and reversals (accelerations), a mismatch between the deceleration rate used by the spacing algorithm and the actual aircraft performance, and some spacing error calculations were sensitive to normal operational variations in aircraft airspeed or altitude which triggered additional IM speed changes. Once the issues in these two categories are addressed, the future IM avionics should have considerable promise supporting the goals of improving system throughput and aircraft efficiency.

    Mao, Lei; Jackson, Lisa

    2016-10-01

    In this paper, sensor selection algorithms are investigated based on a sensitivity analysis, and the capability of optimal sensors in predicting PEM fuel cell performance is also studied using test data. The fuel cell model is developed for generating the sensitivity matrix relating sensor measurements and fuel cell health parameters. From the sensitivity matrix, two sensor selection approaches, including the largest gap method, and exhaustive brute force searching technique, are applied to find the optimal sensors providing reliable predictions. Based on the results, a sensor selection approach considering both sensor sensitivity and noise resistance is proposed to find the optimal sensor set with minimum size. Furthermore, the performance of the optimal sensor set is studied to predict fuel cell performance using test data from a PEM fuel cell system. Results demonstrate that with optimal sensors, the performance of PEM fuel cell can be predicted with good quality.

    Full Text Available Data searching and retrieval is one of the fundamental functionalities in many Web of Things applications, which need to collect, process and analyze huge amounts of sensor stream data. The problem in fact has been well studied for data generated by sensors that are installed at fixed locations; however, challenges emerge along with the popularity of opportunistic sensing applications in which mobile sensors keep reporting observation and measurement data at variable intervals and changing geographical locations. To address these challenges, we develop the Geohash-Grid Tree, a spatial indexing technique specially designed for searching data integrated from heterogeneous sources in a mobile sensing environment. Results of the experiments on a real-world dataset collected from the SmartSantander smart city testbed show that the index structure allows efficient search based on spatial distance, range and time windows in a large time series database.

    Full Text Available The Internet of Things is anticipated to connect billions of embedded devices equipped with sensors to perceive their surroundings. Thereby, the state of the real world will be available online and in real-time and can be combined with other data and services in the Internet to realize novel applications such as Smart Cities, Smart Grids, or Smart Healthcare. This requires an open representation of sensor data and scalable search over data from diverse sources including sensors. In this paper we show how the Semantic Web technologies RDF (an open semantic data format and SPARQL (a query language for RDF-encoded data can be used to address those challenges. In particular, we describe how prediction models can be employed for scalable sensor search, how these prediction models can be encoded as RDF, and how the models can be queried by means of SPARQL.

    NASA and ESA are planning the joint Europa Jupiter System Mission (EJSM) to the Jupiter system with specific emphasis to Europa and Ganymede, respectively. The Japanese Space Agency is also planning an orbiter mission to explore Jupiter's magnetosphere and the Galilean satellites. For NASA's Jupiter Europa Orbiter (JEO) we are developing the 3D Ion Mass Spectrometer (IMS) with two main goals which can also be applied to the other Galilean moons, 1) measure the plasma interaction between Europa and Jupiter's magnetosphere and 2) infer the 4n surface composition to trace elemental [1] and significant isotopic levels. The first goal supports the magnetometer (MAG) measurements, primarily directed at detection of Europa's sub-surface ocean, while the second gives information about transfer of material between the Galilean moons, and between the moon surfaces and subsurface layers putatively including oceans. The measurement of the interactions for all the Galilean moons can be used to trace the in situ ion measurements of pickup ions back to either Europa's or Ganymede's surface from the respectively orbiting spacecraft. The IMS instrument, being developed under NASA's Astrobiology Instrument Development Program, would maximally achieve plasma measurement requirements for JEO and EJSM while moving forward our knowledge of Jupiter system composition and source processes to far higher levels than previously envisaged.

Obwohl sie der sogenannten neuen Welle des Autorenkinos („novaja režisserskaja volna“ zugeordnet werden, fechten die Positionen, die diese Regisseurinnen gegenüber ihren Vorgängern, aber auch ihren Zeitgenossen einnehmen, sowohl in Russland als auch dem Westen eine einfache Zuordnung an. Die Filme bieten einen Einblick in das Anliegen der Regisseurinnen, die gesellschaftlichen und emotionalen Sorgen ihrer Generation auf eine ehrliche und realistische Art und Weise auszudrücken. Eine sorgfältige Untersuchung unterstreicht die unterschiedlich verwendeten, aber dennoch gemeinsamen stilistischen, narrativen und thematischen Elemente, die sie im Film einsetzen. Im Laufe der Untersuchungen begegnet die Aufrichtigkeit nicht nur als diskursives Phänomen, sondern auch als eine vielseitige kulturelle Praxis. Die Mittel, mit denen die einzelnen Filme versuchen bei den Zuschauern eine emotionale Reaktion hervorzurufen, berechtigen die Einordnung einer solchen ästhetischen Taktik als aufrichtig und ehrlich.

    The role of wind power in the industrial sector currently depends very much on its technical and economic integrability in existing conventional supply structures. The most important questions in this context relate to capacity effects, adapted operating methods of conventional power suppliers, and, most important of all, operational energy production costs. In some regions alternative energy supply concepts are not yet or not sufficiently available. However, these will nevertheless offer ways of installing energy systems with a large renewable segment. The chances of bringing such projects to fruition depend for one thing on the climate, which may either stimulate or deter from development work on renewables (wind power, solar energy), and for another, often in apparent opposition to the former, on the oftentimes poorly developed infrastructure and economic strength of the region in question. [Deutsch] Die Bedeutung der Windenergienutzung im industrialisierten Bereich ist derzeit verknuepft mit deren technischen und oekonomischen Integrationsfaehigkeit in bestehende, konventionelle Versorgungsstrukturen. Im Vordergrund steht hierbei die Klaerung der Fragestellungen nach Kapazitaetseffekten, angepassten Betriebsweisen konventioneller Stromerzeuger und, in erster Linie, betriebswirtschaftlichen Energieerzeugungskosten. Derzeit bieten die Regionen, in denen eine anderweitige Versorgung noch nicht oder in nicht ausreichendem Masse existieren Moeglichkeiten zur Installation von Energiesystemen mit hoher regenerativer Durchdringung. Fuer die Realisation solcher Projekte stehen sich haeufig die klimatischen Bedingungen, die einerseits z.T. die Ursache fuer den geringen Entwicklungsstand sind, andererseits aber auch guenstige Voraussetzungen fuer die Nutzung regenerativer Energien (Wind, Sonne) bieten, der meist schlechten Infrastruktur und der geringen Wirtschaftskraft gegenueber.

    Full Text Available Darf man einen Unschuldigen töten? Mit dieser heute noch aktuellen Frage hatten sich bereits die Theologen und Juristen im Spanien des 16. Jahrhunderts auseinanderzusetzen: Darf der Richter im Prozess aufgrund falscher Zeugen wider besseres Wissen einen Unschuldigen zum Tode verurteilen? Ist eine christliche Stadt zur Tötung oder Auslieferung eines Predigers an einen heidnischen Tyrannen berechtigt, wenn davon ihre Existenz abhängt? Muss sich der Prediger von sich aus für das Gemeinwesen opfern? Der Beitrag zeigt, wie neben das „strafrechtliche“ Schuldmodell, wonach der Unschuldige keinen Nachteil verdient und nicht getötet werden darf, in der Spanischen Spätscholastik ein stärker auf Nutzenargumente, insbesondere das Gemeinwohl, abstellendes Utilitätsmodell tritt, das die Tötung des Unschuldigen aus schuldfremden Gründen erlaubt. Damit geht ein Wandel des Staatsverständnisses einher – weg vom Gottesstaat hin zum irdischen Machtstaat, der das Leben seiner Bürger für das Gemeinwesen opfert.

    2015-12-01

    The CTBT International Monitoring System is to be comprised of 337 facilities located all over the world for the purpose of detecting and locating nuclear test explosions. Major challenges remain, namely the completion of the network where most of the remaining stations have either environmental, logistical and/or political issues to surmont (89% of the stations have already been built) and the sustainment of a reliable and state-of the-art network covering 4 technologies - seismic, infrasound , hydroacoustic and radionuclide. To have a credible and trustworthy verification system ready for entry into force of the Treaty, the CTBTO is protecting and enhancing its investment of its global network of stations and is providing effective data to the International Data Centre (IDC) and Member States. Regarding the protection of the CTBTO's investment and enhanced sustainment of IMS station operations, the IMS Division is enhancing the capabilities of the monitoring system by applying advances in instrumentation and introducing new software applications that are fit for purpose. Some examples are the development of noble gas laboratory systems to process and analyse subsoil samples, development of a mobile noble gas system for onsite inspection purposes, optimization of Beta Gamma detectors for Xenon detection, assessing and improving the efficiency of wind noise reduction systems for infrasound stations, development and testing of infrasound stations with a self-calibrating capability, and research into the use of modular designs for the hydroacoustic network.

    Fraga, Carlos G; Melville, Angela M; Wright, Bob W

    2007-03-01

    The detection limit of a field chemical sensor under realistic operating conditions is determined by receiver operator characteristic (ROC) curves. The chemical sensor is an ion mobility spectrometry (IMS) device used to detect a chemical marker in diesel fuel. The detection limit is the lowest concentration of the marker in diesel fuel that obtains the desired true-positive probability (TPP) and false-positive probability (FPP). A TPP of 0.90 and a FPP of 0.10 were selected as acceptable levels for the field sensor in this study. The detection limit under realistic operating conditions is found to be between 2 to 4 ppm (w/w). The upper value is the detection limit under challenging conditions. The ROC-based detection limit is very reliable because it is determined from multiple and repetitive sensor analyses under realistic circumstances. ROC curves also clearly illustrate and gauge the effects data preprocessing and sampling environments have on the sensor's detection limit.

    2002-03-05

    Much attention, in fact an entire session at this conference, is being devoted to protecting the United States against human threats--individuals who may pose a danger by their mere presence on US soil. However, tomorrow's terrorists will employ weapons in their attacks, and we must also be diligent in preventing these weapons from reaching their targets. Sensors can play an important role in detecting these weapons before they achieve their desired effects. A sensor system can best be understood as a way of automating search techniques that would normally be carried out by a human's touch and vision senses, or by a dog's sniffing capabilities. The list of potential threats is long, including nuclear, biological, chemical and radiological weapons, and each presents its own challenges. However, any effective system must meet the following requirements: (1) Sensor systems must be operationally practical. Delays must be kept to a minimum. The systems must be safe to operate. Individual privacy and corporate proprietary information must be protected. The systems must be part of a viable concept of operations; i.e., they must provide information that can enable effective, preemptive actions to be taken. (2) Sensors systems must be highly sensitive, providing a low probability of missed detections (false negatives). Our adversaries will conceal their device from detection, and they will likely probe our defenses for any weaknesses. Our systems must be robust against these techniques. (3) Sensor systems must give a low probability of false alarms (false positives). Our response to the detection of such a weapon will marshal substantial resources and, in many scenarios, be highly disruptive to the general population. Thus a system that gives frequent false alarms will soon be ignored.

    Purpose – The purpose of this paper is to illustrate how biomimetics can be applied in sensor design. Biomimetics is an engineering discipline that uses nature as an inspiration source for generating ideas for how to solve engineering problems. The paper reviews a number of biomimetic studies...... of sense organs in animals and illustrates how a formal search method developed at University of Toronto can be applied to sensor design. Design/methodology/approach – Using biomimetics involves a search for relevant cases, a proper analysis of the biological solutions, identification of design principles...... or the search gives too many results. This is handled by a more advanced search strategy where the search is either widened or it is focused further mainly using biological synonyms. Findings – A major problem in biomimetic design is finding the relevant analogies to actual design tasks in nature. Research...

    Purpose: Prospective evaluation of the accuracy of three-dimensional ultrasound (3DUS) to assess the renal parenchymal volume. Materials and Methods: CT, MRI, 2DUS and 3DUS were used to measure the renal volume in 40 patients (range: neonate to 17 years; mean age: 8.95 years). The 3DUS was determined with a Voluson 730 (Kretztechnik, GE) or an external 3D-system (EchoTech, GE) using electromagnetic positioning sensors attached to conventional 2DUS-equipment. The 2DUS volume was calculated with the ellipsoid equation and the 3DUS volume computed with the system integrated software. For CT and MRI, planimetric analysis was used to determine the renal parenchymal volume, whereby the dilated collecting system of a hydronephrosis was subtracted to obtain the real renal parenchymal volume. The results of 2DUS and 3DUS were compared to the results of CT and MRI, and inter- and intraobserver variabilities were calculated. Results: In 74 of 77 kidneys, the 3DUS study was of diagnostic quality. The accuracy of the 3DUS volumes compared well to the CT and MRI volumes with a mean difference of -1.8 {+-} 4.6% versus a mean difference of -2.4 {+-} 15.4% for 2DUS. In normal kidneys, the accuracy was -2.6 {+-} 4.4% for 3DUS and -3.8 {+-} 14.7% for 2DUS. In hydronephrosis, the accuracy was +4.0 {+-} 5.9% and +9.6 {+-} 21.3%, respectively, indicating that 3DUS is more accurate than 2DUS, particularly in kidneys with a dilated collecting system. Inter- and intraobserver variabilities were {+-} 7.3% and {+-} 5.3%. Conclusion: For assessing the renal parenchymal volume in children, 3DUS is feasible and comparable to CT and MRI. (orig.)

    The closer the end of coal mining in 2018, the more the issue of groundwater re-emergence in the Ruhr area is also being considered. This is especially the case because currently the subject of restitution and liability issues in the area of contaminated sites of the peaceful use of nuclear energy is discussed. In addition, the companies concerned lost considerable value on the stock market. For this reason, the question of whether the financial provisions in the created foundation are sufficient to shoulder the expected responsibilities and measures also arises with regard to coal mining. The question is which measures are to be taken and where damages can occur. Additional impulses are given by the Meggen judgment of the BVerwG of 18.12.2014, which interpreted the responsibility of the mining companies very widely. In the Rhineland, an earthquake hit 2.4 on 22.12.2015 - probably due to a rise in groundwater around the closed opencast mine Bergheim. All these questions are included in the colloquium on economics and environmental law on 26 January 2016. This also includes experiences and problems from other federal states such as Brandenburg and Saxony.

  7. Planning and Scheduling for Environmental Sensor Networks

    Frank, J. D.

    2005-12-01

    Environmental Sensor Networks are a new way of monitoring the environment. They comprise autonomous sensor nodes in the environment that record real-time data, which is retrieved, analyzed, integrated with other data sets (e.g. satellite images, GIS, process models) and ultimately lead to scientific discoveries. Sensor networks must operate within time and resource constraints. Sensors have limited onboard memory, energy, computational power, communications windows and communications bandwidth. The value of data will depend on when, where and how it was collected, how detailed the data is, how long it takes to integrate the data, and how important the data was to the original scientific question. Planning and scheduling of sensor networks is necessary for effective, safe operations in the face of these constraints. For example, power bus limitations may preclude sensors from simultaneously collecting data and communicating without damaging the sensor; planners and schedulers can ensure these operations are ordered so that they do not happen simultaneously. Planning and scheduling can also ensure best use of the sensor network to maximize the value of collected science data. For example, if data is best recorded using a particular camera angle but it is costly in time and energy to achieve this, planners and schedulers can search for times when time and energy are available to achieve the optimal camera angle. Planning and scheduling can handle uncertainty in the problem specification; planners can be re-run when new information is made available, or can generate plans that include contingencies. For example, if bad weather may prevent the collection of data, a contingent plan can check lighting conditions and turn off data collection to save resources if lighting is not ideal. Both mobile and immobile sensors can benefit from planning and scheduling. For example, data collection on otherwise passive sensors can be halted to preserve limited power and memory

Both IM and the existing commercial Virtual Reference (VR software were offered in tandem for one semester. The services were evaluated through a combination of statistical reports and survey data gathered from both the users and service providers. Comparison of statistics revealed a 44% increase in online sessions, with 22% more sessions received by the IM service. Although users displayed satisfaction with both of the online services, they preferred IM over the VR software. The IM chat widget was reported as the most preferred method for receiving library reference services overall, including face-to-face, telephone and email. Both undergraduate and graduate students preferred the IM service, while faculty and other patron groups did not have a significant enough response rate to assure an accurate measure. After the initial learning curve, service providers preferred delivering online reference by IM over the commercial VR platform. Based on these results, Novanet’s Live Help service will switch to a multi-protocol IM-based service with a chat widget in the fall of 2008.

    Motor vehicles contribute much to urban air pollution. As a result, most governments have enacted emission standards that significantly lower pollutant emission levels from new motor vehicles. For example, vehicles built in the United States emit 95 % fewer pollutants than uncontrolled vehicles when they are new. However, studies indicate that proper maintenance is needed to obtain the full benefit of vehicle emission controls. Furthermore, there is evidence that a significant percentage of the vehicle fleet is not properly maintained. This has led to the creation of motor vehicle Inspection/Maintenance (I/M) Programs. I/M programs inspect vehicles for indications that they are emitting excessive quantities of pollutants. Vehicles that fail the inspection must be repaired in order to comply with program requirements. The first I/M programs were implemented in the United States in the early 1970s. With substantial urging from the federal government, most of the U.S. states with severe air pollution problems have implemented I/M programs. Recently, with the passage of the U.S. Clean Air Act Amendments of 1990, many states have been required to significantly upgrade the performance and coverage of their I/M programs. I/M programs also have been implemented in Europe and recently in Asia. This presentation reviews developments in I/M programs for light-duty gasoline powered vehicles. Developments in I/M programs for diesel powered vehicles are briefly described. (author)

  4. Information-based sensor management for the intelligent tasking of ground penetrating radar and electromagnetic induction sensors in landmine detection pre-screening

    Science.gov (United States)

    Kolba, Mark P.; Collins, Leslie M.

    2010-04-01

    Previous work has introduced a framework for information-based sensor management that is capable of tasking multiple sensors searching for targets among a set of discrete objects or in a cell grid. However, in many real-world scenarios-- such as detecting landmines along a lane or road--an unknown number of targets are present in a continuous spatial region of interest. Consequently, this paper introduces a grid-free sensor management approach that allows multiple sensors to be managed in a sequential search for targets in a grid-free spatial region. Simple yet expressive Gaussian target models are introduced to model the spatial target responses that are observed by the sensors. The sensor manager is then formulated using a Bayesian approach, and sensors are directed to make new observations that maximize the expected information gain between the posterior density on the target parameters after a new observation and the current posterior target parameter density. The grid-free sensor manager is applied to a set of real landmine detection data collected with ground penetrating radar (GPR) and electromagnetic induction (EMI) sensors at a U.S. government test site. Results are presented that compare the performance of the sensor manager with the performance of an unmanaged joint pre-screener that fuses individual GPR and EMI pre-screeners. The sensor manager is demonstrated to provide improved detection performance while requiring substantially fewer sensor observations than are made with the unmanaged joint pre-screening approach.

    Full Text Available Bildgebende Verfahren sind eine wichtige Grundlage der Therapieplanung und -kontrolle bei Hirntumoren. Bislang diente hierzu in erster Linie die Größenbeurteilung auf herkömmlichen morphologischen MRT-Aufnahmen. Sowohl zur besseren Therapieplanung und -kontrolle im Rahmen etablierter Therapieschemata als auch zur Evaluation neuer Therapieverfahren ist die Erfassung physiologischer Parameter wie der Perfusion, Diffusion oder Permeabilität mithilfe von MRT und PET eine vielversprechende Entwicklung. Mit der PET und entsprechenden Tracern können zusätzlich auch Targets zur Tumorklassifikation oder gezielten Therapie nachgewiesen werden. Mit der Spektroskopie können für Tumorgewebe typische Metabolite nachgewiesen werden. Bei einigen Tumorentitäten wie den niedergradigen Gliomen zeigten Studien, dass die Perfusionsbildgebung hilfreich zur Planung des weiteren therapeutischen Vorgehens sein kann. Ziel ist, durch eine Kombination geeigneter Verfahren zu einer frühen und treffsicheren Diagnostik beizutragen.

    IM Per is a detached A7 eccentric eclipsing binary star. We have obtained extensive measurements of the light curve (28,225 differential magnitude observations) and radial velocity curve (81 spectroscopic observations) which allow us to fit orbits and determine the absolute properties of the components very accurately: masses of 1.7831 ± 0.0094 and 1.7741 ± 0.0097 solar masses, and radii of 2.409 ± 0.018 and 2.366 ± 0.017 solar radii. The orbital period is 2.25422694(15) days and the eccentricity is 0.0473(26). A faint third component was detected in the analysis of the light curves, and also directly observed in the spectra. The observed rate of apsidal motion is consistent with theory (U = 151.4 ± 8.4 year). We determine a distance to the system of 566 ± 46 pc.

    Full Text Available To fully benefit from the all IP convergence, it should be possible for a user not only to access services ubiquitously and at any time, but also to automatically and seamlessly transfer ongoing communication between different devices. This article investigates the problem space of supporting Session Mobility (SM with IMS and the associated issues such as when and how to support dynamic changes in the set of devices through which the user accesses a session. It also investigates how the SM arrival calls should be handled at the network level where they are not considered as ongoing sessions. Hence, we discuss the design options and identify functional blocks needed to support SM. We propose applying priority-based resource allocation approach to guarantee lower blocking probability for ongoing SM arrival calls compared to new arrival calls. Numerical results show that this approach allows achieving such performance for different call arrival rates.

    The Fateev model is somewhat special among two-dimensional quantum field theories. For different values of the parameters,it can be reduced to a variety of integrable systems. An incomplete list of the reductions includes O(3) and O(4) non-linear sigma models and their continuous deformations (2D and 3D sausages, anisotropic principal chiral field), the Bukhvostov-Lipatov model, the N=2 supersymmetric sine-Gordon model, as well as the integrable perturbed SU_2(n)\\otimes SU_2(p-2)/SU_2(n+p-2) coset CFT. The model possesses a mysterious symmetry structure of the exceptional quantum superalgebras U_q{\\hat{\\big(D(2|1;\\alpha)}}\\big). In this work, we propose the ODE/IM correspondence between the Fateev model and a certain generalization of the classical problem of constant mean curvature embedding of a thrice-punctured sphere in AdS_3.

    Sensors and sensor systems are vital to our awareness of our surroundings and provide safety, security, and surveillance, as well as enable monitoring of our health and environment. A transformative advance in the field of sensor technology has been the development of "Smart Sensor Systems". The definition of a Smart Sensor may vary, but typically at a minimum a Smart Sensor is the combination of a sensing element with processing capabilities provided by a microprocessor. That is, Smart Sensors are basic sensing elements with embedded intelligence. The sensor signal is fed to the microprocessor, which processes the data and provides an informative output to an external user. A more expansive view of a Smart Sensor System, which is used in this article, is illustrated in Fig. 19.1: a complete self-contained sensor system that includes the capabilities for logging, processing with a model of sensor response and other data, self-contained power, and an ability to transmit or display informative data to an outside user. The fundamental idea of a smart sensor is that the integration of silicon microprocessors with sensor technology cannot only provide interpretive power and customized outputs, but also significantly improve sensor system performance and capabilities.

    Under appropriate conditions, the four-helical Im7 (immunity protein 7) folds from an ensemble of unfolded conformers to a highly compact native state via an on-pathway intermediate. Here, we investigate the unfolded, intermediate, and native states populated during folding using diffusion single-pair fluorescence resonance energy transfer by measuring the efficiency of energy transfer (or proximity or P ratio) between pairs of fluorophores introduced into the side chains of cysteine residues placed in the center of helices 1 and 4, 1 and 3, or 2 and 4. We show that while the native states of each variant give rise to a single narrow distribution with high P values, the distributions of the intermediates trapped at equilibrium (denoted I(eqm)) are fitted by two Gaussian distributions. Modulation of the folding conditions from those that stabilize the intermediate to those that destabilize the intermediate enabled the distribution of lower P value to be assigned to the population of the unfolded ensemble in equilibrium with the intermediate state. The reduced stability of the I(eqm) variants allowed analysis of the effect of denaturant concentration on the compaction and breadth of the unfolded state ensemble to be quantified from 0 to 6 M urea. Significant compaction is observed as the concentration of urea is decreased in both the presence and absence of sodium sulfate, as previously reported for a variety of proteins. In the presence of Na(2)SO(4) in 0 M urea, the P value of the unfolded state ensemble approaches that of the native state. Concurrent with compaction, the ensemble displays increased peak width of P values, possibly reflecting a reduction in the rate of conformational exchange among iso-energetic unfolded, but compact conformations. The results provide new insights into the initial stages of folding of Im7 and suggest that the unfolded state is highly conformationally constrained at the outset of folding.

    Wireless sensor networks have been identified as one of the most important technologies for the 21st century. Recent advances in micro sensor fabrication technology and wireless communication technology enable the practical deployment of large-scale, low-power, inexpensive sensor networks. Such an approach offers an advantage over traditional sensing methods in many ways: large-scale, dense deployment not only extends spatial coverage and achieves higher resolution, but also increases the system's fault-tolerance and robustness. Moreover, the ad-hoc nature of wireless sensor networks makes them even more attractive for military and other risk-associated applications, such as environmental observation and habitat monitoring.

  2. Faceted Semantic Search for Personalized Social Search

    Actual social networks (like Facebook, Twitter, Linkedin, ...) need to deal with vagueness on ontological indeterminacy. In this paper is analyzed the prototyping of a faceted semantic search for personalized social search using the "joint meaning" in a community environment. User researches in a "collaborative" environment defined by folksonomies can be supported by the most common features on the faceted semantic search. A solution for the context-aware personalized search is based on "joint meaning" understood as a joint construal of the creators of the contents and the user of the contents using the faced taxonomy with the Semantic Web. A proof-of concept prototype shows how the proposed methodological approach can also be applied to existing presentation components, built with different languages and/or component technologies.

    Full Text Available Im Sinne einer pragmatistischen Perspektive, wie sie zuerst John DEWEY (1987 [1934] in Anschluss an William JAMES formulierte, ist das Religiöse weniger als eine spezifische Art von experience zu verstehen, denn als ein adjustment hin zu einer epistemischen Perspektive, die alle Erfahrungen in einem veränderten Licht erscheinen lässt. Religiosität zielt damit auf ein besonderes Selbst- und Weltverhältnis, in dem die Beziehung zwischen Selbst und Welt aus einer ganzheitlichen Perspektive betrachtet wird. Wie aber können fremde, auf den ersten Blick in ihrer Genese unwahrscheinliche und unter modernen Verhältnissen zudem anzweifelbare religiöse Haltungen und Sinnsysteme etabliert werden? Am Beispiel der im tibetischen Buddhismus verbreiteten Phowa-Meditation des "bewussten Sterbens" wird untersucht, wie für westliche Adept/innen auf den ersten Blick befremdlich und esoterisch anmutende spirituelle Lehren mit zunehmender Praxis an Evidenz und Sinnhaftigkeit gewinnen können, indem sich Gruppenprozesse, Visualisierungen, körperorientierte Übungen und psychisches Erleben zu einem übergreifenden Arrangement verschränken. Die empirische Datengrundlage für die Untersuchung liefern narrative Interviews mit westlich sozialisierten Schüler/innen und Lehrer/innen des Diamantweg-Buddhismus, der derzeit größten buddhistischen Gemeinschaft des tibetischen Buddhismus in Deutschland. Die Auswertung der Interviews erfolgte angelehnt an die dokumentarische Methode, erweitert durch eine Kontexturanalyse, um den Reflexionsverhältnissen gerecht zu werden, die den religiösen Selbst- und Weltbezug aufspannen.

    2001-01-01

    Sensor networks are being widely deployed for measurement, detection and surveillance applications. In these new applications, users issue long-running queries over a combination of stored data and sensor data. Most existing applications rely on a centralized system for collecting sensor data....... These systems lack flexibility because data is extracted in a predefined way; also, they do not scale to a large number of devices because large volumes of raw data are transferred regardless of the queries that are submitted. In our new concept of sensor database system, queries dictate which data is extracted...... from the sensors. In this paper, we define the concept of sensor databases mixing stored data represented as relations and sensor data represented as time series. Each long-running query formulated over a sensor database defines a persistent view, which is maintained during a given time interval. We...

    Sensors are one of the key elements for the automation in the manufacturing and process technology. The sensor field is presently within a restructuring process, directed to a stronger utilization of solid state technologies. This restructuring is governed by the utilization of solid state physical effects, by the use of reproducible fabrication techniques, and by the market driving forces. The state of the art of sensors in modern fabrication techniques will be demonstrated in examples, namely for sensors in silicon technology, in thin film technology and in thick film/screen printing technology. Some important physical and technological problems to be solved for the development of new and advanced sensor families will be outlined. Sensor development is strongly directed to the minaturization of devices and to the integration of different sensors to multisensors, as well as the integration between sensors and microelectronics.

Android, a software platformfrom Google, pioneering in middleware and applications domain of handheld devices does not offersupport for IMS services by design.Motivated by these observations, we present novel scalable architecture to cater IMS basedservices on Android. First, we discuss few related works to investigate and analyze the IMS and the roleof SIP in IMS services. Second, we discuss few characteristics of android architecture and detailconstraints associated with middleware sub-system to cater IMS services. Consequently, we describe theproposed architecture addressing inherent challenges like QoS, Extendibility and Security encounteredwhile offering IMS based services. The architectural framework design reduces time-to-deployment byusing a layered approach encompassing three layers, namely: QoE Engine, Advanced IMS Service Core(A-IMS and Application Services Engine (ASE. The A-IMS core is responsible to provide End-2-Endefficient service delivery of IMS services like VOIP. We point out the benefits of using the ASE andgeneric media management and control interface (GMMCI to ensure smooth and swift portability ontodifferent flavors of android. Finally, we conclude by detailing some use-cases of future IMS services likeVideo Sharing/Video Recording in an on-going Video Telephony Call

    2006-06-01

    Full Text Available Some wetlands from the central part of Spain have been here studied. There are big differences between field work and images taken by some sensors of environmental satellites. Usually, on summer, when these ponds dry up, the seasonal wetlands exhibit a whitish surface due to salt precipitation, contrasting with the bluish colour displayed in images. It has been suggested that this apparent paradox results from the fact that sensor records data from an three-dimensional earth and not only from a simple surface. Therefore, in Mediterranean semiarid region satellite images can be used to discriminate wetlands fed by groundwater from other ones having a non sub-surface water contribution.

    En el presente trabajo se han analizado varios humedales del centro de España. Se han observado grandes diferencias entre los datos obtenidos en el trabajo de campo y la información suministrada por algunos satélites medio ambientales. Normalmente, en verano, cuando las lagunas están secas, los humedales estacionales muestran una superficie blanquecina debida a la precipitación de las sales, que contrasta con el color azulado de estos humedales en las imágenes de satélite. Se sugiere que esta aparente paradoja puede ser debida al hecho de que el sensor capta información tridimensional y no sólo la superficie de las lagunas. A veces, en las regiones mediterráneas semiáridas las imágenes de satélite se pueden utilizar para diferenciar los humedales alimentados con aguas subterráneas de aquellos que no tienen contribución de aguas subsuperficiales.

  5. Coordinated sensor cueing for chemical plume detection

    Abraham, Nathan J.; Jensenius, Andrea M.; Watkins, Adam S.; Hawthorne, R. Chad; Stepnitz, Brian J.

    2011-05-01

    This paper describes an organic data fusion and sensor cueing approach for Chemical, Biological, Radiological, and Nuclear (CBRN) sensors. The Joint Warning and Reporting Network (JWARN) uses a hardware component referred to as the JWARN Component Interface Device (JCID). The Edgewood Chemical and Biological Center has developed a small footprint and open architecture solution for the JCID capability called JCID-on-a-Chip (JoaC). The JoaC program aims to reduce the cost and complexity of the JCID by shrinking the necessary functionality down to a small single board computer. This effort focused on development of a fusion and cueing algorithm organic to the JoaC hardware. By embedding this capability in the JoaC, sensors have the ability to receive and process cues from other sensors without the use of a complex and costly centralized infrastructure. Additionally, the JoaC software is hardware agnostic, as evidenced by its drop-in inclusion in two different system-on-a-chip platforms including Windows CE and LINUX environments. In this effort, a partnership between JPM-CA, JHU/APL, and the Edgewood Chemical and Biological Center (ECBC), the authors implemented and demonstrated a new algorithm for cooperative detection and localization of a chemical agent plume. This experiment used a pair of mobile Joint Services Lightweight Standoff Chemical Agent Detector (JSLSCAD) units which were controlled by fusion and cueing algorithms hosted on a JoaC. The algorithms embedded in the JoaC enabled the two sensor systems to perform cross cueing and cooperatively form a higher fidelity estimate of chemical releases by combining sensor readings. Additionally, each JSLSCAD had the ability to focus its search on smaller regions than those required by a single sensor system by using the cross cue information from the other sensor.

  6. Spaced-based search coil magnetometers

    Hospodarsky, George B.

    2016-12-01

    Search coil magnetometers are one of the primary tools used to study the magnetic component of low-frequency electromagnetic waves in space. Their relatively small size, mass, and power consumption, coupled with a good frequency range and sensitivity, make them ideal for spaceflight applications. The basic design of a search coil magnetometer consists of many thousands of turns of wire wound on a high permeability core. When a time-varying magnetic field passes through the coil, a time-varying voltage is induced due to Faraday's law of magnetic induction. The output of the coil is usually attached to a preamplifier, which amplifies the induced voltage and conditions the signal for transmission to the main electronics (usually a low-frequency radio receiver). Search coil magnetometers are usually used in conjunction with electric field antenna to measure electromagnetic plasma waves in the frequency range of a few hertz to a few tens of kilohertzs. Search coil magnetometers are used to determine the properties of waves, such as comparing the relative electric and magnetic field amplitudes of the waves, or to investigate wave propagation parameters, such as Poynting flux and wave normal vectors. On a spinning spacecraft, they are also sometimes used to determine the background magnetic field. This paper presents some of the basic design criteria of search coil magnetometers and discusses design characteristics of sensors flown on a number of spacecraft.

  15. Rotorwash wind sensor evaluation

    Meyerhoff, Curtis L.; Lake, Robert E.; Gordge, Dennis N.

    1993-08-01

    This project's purpose was to assess and document the ability of the Qualimetrics, Inc. model 2132 wind sensor (a cup and vane type sensor) to measure a rotor wash flow field as compared to the TSI, Inc. model 204D ion beam deflection sensor. The tests concentrated on the sensor's ability to capture dynamic characteristics of a helicopter rotor wash flow field. The project was conducted from April to November 1992 and consisted of quantitative laboratory and field testing. The laboratory testing included 9.5 hours of wind tunnel test time, subjecting each sensor to three step input tests at velocities of 20 knots, 50 knots, and 80 knots. Field test data were collected during one hour of SH-60B helicopter hover time at heights of 15 and 25 feet above ground level at distances of 35 and 70 feet from the wind sensors. Aircraft gross weights ranged between 19,600 and 20,500 pounds. All field test data were obtained in ambient wind conditions of approximately 8 knots at 40 degrees relative to the aircraft nose, -40 feet pressure altitude in an ambient temperature of 85 F. Laboratory data analysis indicates the model 2132 cup and vane sensor's time constant values were significantly higher than those of the model 204D ion beam sensor and varied relative to wind tunnel velocity settings. This indicates the model 2132 sensor's ability to accurately capture oscillations in a dynamic flow field is significantly less than the model 204D sensor. The model 2132 sensor did detect periodic or pulsating velocity magnitudes, but failed to capture significant oscillations as compared to the model 204D sensor. Comparative analysis of all field test event data indicate the model 2132 sensor only detected frequencies below 1.5 Hz and only captured an average of 46 percent of the model 204D sensor's maximum amplitude pulse values that were below 1.5 Hz. The model 2132 sensor's inability to capture many of the maximum pulse amplitudes is evidence of the sensor's limited capability to

    Large neighborhood search is a metaheuristic that has gained popularity in recent years. The heuristic repeatedly moves from solution to solution by first partially destroying the solution and then repairing it. The best solution observed during this search is presented as the final solution....... This tutorial introduces the large neighborhood search metaheuristic and the variant adaptive large neighborhood search that dynamically tunes parameters of the heuristic while it is running. Both heuristics belong to a broader class of heuristics that are searching a solution space using very large...... neighborhoods. The tutorial also present applications of the adaptive large neighborhood search, mostly related to vehicle routing problems for which the heuristic has been extremely successful. We discuss how the heuristic can be parallelized and thereby take advantage of modern desktop computers...

    This paper presents findings from a laboratory experiment on human decision-making in a complex combinatorial task. We find strong evidence for a behavioral model of adaptive search. Success narrows down search to the neighborhood of the status quo, while failure promotes gradually more explorative...... search. Task complexity does not have a direct effect on behavior, but systematically affects the feedback conditions that guide success-induced exploitation and failure-induced exploration. The analysis also shows that human participants were prone to over-exploration, since they broke off the search...... for local improvements too early. We derive stylized decision rules that generate the search behavior observed in the experiment and discuss the implications of our findings for individual decision-making and organizational search....

    There is broad consensus in the field of IR that search is complex in many use cases and applications, both on the Web and in domain specific collections, and both professionally and in our daily life. Yet our understanding of complex search tasks, in comparison to simple look up tasks......, is fragmented at best. The workshop addressed the many open research questions: What are the obvious use cases and applications of complex search? What are essential features of work tasks and search tasks to take into account? And how do these evolve over time? With a multitude of information, varying from...... introductory to specialized, and from authoritative to speculative or opinionated, when to show what sources of information? How does the information seeking process evolve and what are relevant differences between different stages? With complex task and search process management, blending searching, browsing...

    Full Text Available Nachlässe rücken in der wissenschaftlichen Forschung immer mehr in den Fokus, wie etwa die stark gestiegenen Nutzerzahlen der Bayerischen Staatsbibliothek (BSB über die letzten Jahre hinweg deutlich zeigen. Umso wichtiger ist insbesondere für Bibliotheken mit umfangreichen und fachlich breit gestreuten Nachlassbeständen eine möglichst genaue Erschließung im Internet, um der wissenschaftlichen Forschung einen schnellen Zugriff auf diese unikalen Materialien zu ermöglichen. Bei der digitalen Bereitstellung und vernetzten Erschließung verfolgt die BSB mit ihren rund 1.100 Nachlässen eine doppelte Strategie. Einerseits wird versucht, ausgewählte Nachlässe im Verbundsystem Kalliope zu katalogisieren. Andererseits werden die Erschließungsdaten zu den bereits erschlossenen und den erst grob geordneten Nachlässen, die in Form von hand- oder maschinenschriftlichen Listen sowie als Wordlisten vorliegen, digitalisiert und über den Bibliothekskatalog online zur Verfügung gestellt, um den Nutzern die Möglichkeit zu geben, sich so über die vorhandenen Bestände zu informieren. Wie dieses Projekt genau durchgeführt wurde, ist Gegenstand des Artikels. Special collections and personal papers are becoming more and more important for academic research, as is shown clearly by the increasing usage numbers at the Bavarian State Library (BSB over the last couple of years. Especially for libraries with extensive and manifold collections of estates, it is important to present these unique materials in a well-indexed manner on the internet, in order to give the scientific community easy access. The Bavarian State Library, which keeps more than 1.100 estates of personal papers, pursues a double strategy: On the one hand, selected estates are fully cataloged in the database “Kalliope”. As this procedure is likely to take a long time, the library on the other hand has been digitizing older hand- or typewritten lists with information

    The search of images on the internet has become a natural process for the internet surfer. Most of the search engines use complex algorithms to look up for images but their metadata is mostly ignored, in part because many image hosting sites remove metadata when the image is uploaded. The JPSearch standard has been developed to handle interoperability in metadata based searches, but it seems that the market is not interested on supporting it. The starting point of this proje...

  4. Virtual Sensor Test Instrumentation

    2011-01-01

    Virtual Sensor Test Instrumentation is based on the concept of smart sensor technology for testing with intelligence needed to perform sell-diagnosis of health, and to participate in a hierarchy of health determination at sensor, process, and system levels. A virtual sensor test instrumentation consists of five elements: (1) a common sensor interface, (2) microprocessor, (3) wireless interface, (4) signal conditioning and ADC/DAC (analog-to-digital conversion/ digital-to-analog conversion), and (5) onboard EEPROM (electrically erasable programmable read-only memory) for metadata storage and executable software to create powerful, scalable, reconfigurable, and reliable embedded and distributed test instruments. In order to maximize the efficient data conversion through the smart sensor node, plug-and-play functionality is required to interface with traditional sensors to enhance their identity and capabilities for data processing and communications. Virtual sensor test instrumentation can be accessible wirelessly via a Network Capable Application Processor (NCAP) or a Smart Transducer Interlace Module (STIM) that may be managed under real-time rule engines for mission-critical applications. The transducer senses the physical quantity being measured and converts it into an electrical signal. The signal is fed to an A/D converter, and is ready for use by the processor to execute functional transformation based on the sensor characteristics stored in a Transducer Electronic Data Sheet (TEDS). Virtual sensor test instrumentation is built upon an open-system architecture with standardized protocol modules/stacks to interface with industry standards and commonly used software. One major benefit for deploying the virtual sensor test instrumentation is the ability, through a plug-and-play common interface, to convert raw sensor data in either analog or digital form, to an IEEE 1451 standard-based smart sensor, which has instructions to program sensors for a wide variety of

  7. Nicht nur Schall und Rauch:Zum Umgang mit Namen im Biologieunterricht

    OpenAIRE

    2003-01-01

    Namen sind Wörter, die Individuen bezeichnen. Das Namengeben hat im täglichen Leben emotionale und Beziehungen stiftende Bedeutung. Dieses wird im Unterricht viel zu wenig beachtet. Die Namen für die Organismen und Organismengruppen können anschaulich sein und dann das Lernen der biologischen Sachverhalte fördern, aber auch behindern. Im Beitrag wird diese Frage anhand empirischer Befunde erörtert und es werden daraus Vorschläge für den Biologieunterricht abgeleitet.

    The present paper presents an method of using fiber Michelson interferometer to measure the Intensity-frequency (IM/FM) phase delay change of the laser, it could realize the phase delay time measurement, while modulating the laser. Experimental results show that the laser output signal intensity-frequency (IM/FM) phase delay of the laser has some differences from the theoretical value. The proposed method can be used to compensate for real-time signal strength-frequency (IM/FM) phase delay effect on the gas concentration measurement results.

    Full Text Available In three studies, we examined factors that may temporarily attenuate information search. People are generally curious and dislike uncertainty, which typically encourages them to look for relevant information. Despite these strong forces that promote information search, people sometimes deliberately delay obtaining valuable information. We find they may do so when they are concerned that the information might interfere with future pleasurable activities. Interestingly, the decision to search or to postpone searching for information is influenced not only by the value and importance of the information itself but also by well-being maintenance goals related to possible detrimental effects that negative knowledge may have on unrelated future plans.

    The use of multiple sensors typically requires the fusion of data from different type of sensors. The combined use of such a data has the potential to give an efficient, high quality and reliable estimation. Input data from different sensors allows the introduction of target attributes (target type......, size) into the association logic. This requires a more general association logic, in which both the physical position parameters and the target attributes can be used simultaneously. Although, the data fusion from a number of sensors could provide better and reliable estimation but abundance...... processing units for same type of multiple sensors, typically radar in our case....

    Many emerging IoT applications require sensing of multiple physical and environmental parameters for: completeness of information, measurement validation, unexpected demands, improved performance. For example, a typical outdoor weather station measures temperature, humidity, barometric pressure, light intensity, rainfall, wind speed and direction. Existing sensor technologies do not directly address the demand for cost, size, and power reduction in multi-paramater sensing applications. Industry sensor manufacturers have developed integrated sensor systems for inertial measurements that combine accelerometers, gyroscopes, and magnetometers, but do not address environmental sensing functionality. In existing research literature, a technology gap exists between the functionality of MEMS sensors and the real world applications of the sensors systems.

    Full Text Available der Einsatz von Medien als Lehrmittel – aber vor allem als Informations- und Kommunikationsinstrument – erfordert, so wie das suchende Lernen in vernetzten auf Hypertext basierenden virtuellen Räumen, eine multimediale Schreib- und Lesekompetenz, die nicht auf lineare Schrifttexte begrenzt ist. Die Förderung der Medienkompetenz der Lehrenden sowohl in der Hochschule als auch in der Schule ist daher eine der wichtigen Aufgaben des Bildungssystems in unserer heutigen Wissens-, Informations- und Mediengesellschaft. Diese Konstellation wirkt sich direkt auf die Frage nach der Zukunft von Medienbildung und Medienpädagogik aus, weshalb sich die Redaktion der MEDIENIMPULSE entschlossen hat, dem Thema PädagogInnenbildung NEU ihre Schwerpunktausgabe 3/2012 zu widmen.Auf allgemeiner Ebene haben bm:ukk und bmwf – wie im letzten Regierungsprogramm verankert – schon früh festgehalten, dass die Erstellung eines Konzepts nötig ist, das der Bologna-Struktur entspricht und dabei eine zwischen Universitäten und Pädagogischen Hochschulen abgestimmte Neuorganisation der verschiedenen Lehramtsstudien entwickelt werden muss. Zu diesem Zweck wurde eine Vorbereitungsgruppe zur PädagogInnenbildung Neu unter der Leitung von Peter Härtel eingesetzt, deren Endbericht nach langen Diskussionen am 27.

    2015-01-01

    The High Energy Stereoscopic System (H.E.S.S.) very high energy gamma-ray telescope array has added a fifth telescope of 600 m$^{2}$ mirror area to the centre of the 4 existing telescopes, lowering its energy threshold to the sub-100 GeV range and becoming the first operational IACT array using multiple telescope designs. In order to properly access this low-energy range however, some adaptation must be made to the existing event analysis. We present an adaptation of the high-performance event reconstruction algorithm, Image Pixelwise fit for Atmospheric Cherenkov Telescopes (ImPACT), for performing mono and stereo event reconstruction with the H.E.S.S. II array. The reconstruction algorithm is based around the likelihood fitting of camera pixel amplitudes to an expected image template, directly generated from Monte Carlo simulations. This advanced reconstruction is combined with a multi variate analysis based background rejection scheme to provide a sensitive and stable analysis scheme in the sub-100 GeV gam...

    Full Text Available La investigación sobre el sistema visual condujo a la emergencia de modelos basados en los componentes neurales de dicho sistema, que permiten describir el modo en que es extraída la información de velocidad contenida en una escena con movimiento. El hecho de que estos modelos sean sensibles al tamaño de los estímulos presentados en la retina en combinación con el cambio de tamaño debido a la distancia a la cual se presentan los objetos, llevó a la pregunta acerca de cómo es posible la percepción de una velocidad constante, independientemente de la distancia a la cual se desplazan los objetos. En este trabajo revisamos las investigaciones realizadas sobre la constancia de la velocidad percibida e indagamos acerca de la importancia de la familiaridad de los objetos en movimiento. Por medio de experimentos psicofísicos con imágenes naturales, mostramos que la familiaridad juega un rol importante al momento de asignar perceptualmente la velocidad de un objeto en movimiento.

    Full Text Available In the current networking field many research works are going on regarding the integration of different wireless technologies, with the aim of providing uninterrupted connectivity to the user anywhere, with high data rates due to increased demand. However, the number of objects like smart devices, industrial machines, smart homes, connected by wireless interface is dramatically increasing due to the evolution of cloud computing and internet of things technology. This Paper begins with the challenges involved in such integrations and then explains the role of different couplings and different architectures. This paper also gives further improvement in the LTE and Wimax integration architectures to provide seamless vertical handover and flexible quality of service for supporting voice, video, multimedia services over IP network and mobility management with the help of IMS networks. Evaluation of various parameters like handover delay, cost of signalling, packet loss,, is done and the performance of the interworking architecture is analysed from the simulation results. Finally, it concludes that the cross layer scenario is better than the non cross layer scenario.

    Full Text Available Schlöndorffs Filme Die verlorene Ehre der Katharina Blum und Die Stille nach dem Schuss spiegeln in signifikanter Weise einen Wandel des intellektuellen Diskurses über Politik in Deutschland nach 1945, zugleich konturieren sie ihn mit unterschiedlichen ästhetischen Mitteln. Die Verlorene Ehre der Katharina Blum rekonstruiert die ideologische Situation des Jahres 1968, in der Schlöndorff in enger Zusammenarbeit mit Böll eine markante Position bezieht, die Stille nach dem Schuss skizziert demgegenüber eine Bewusstseinslage, in der erstmals nach der Wende des Jahres 1989 die politischen und ideologischen Widersprüche innerhalb der früheren DDR und die Aufarbeitung der Stasivergangenheit offen thematisiert werden. Dabei beleuchtet Schlöndorff zugleich kritisch die eigene Haltung als westlicher Intellektueller gegenüber der DDR und im vereinigten Deutschland. Dagegen machen die neueren Filme Der Baader Meinhof Komplex und Die innere Sicherheit auf je unterschiedliche Weise die Neubewertung der Außerparlamentarischen Opposition und der Baader Meinhof Gruppe deutlich, die ebenfalls nach 1989 einsetzt. Dabei führt der Film von Eichinger und Edel zu einer Historisierung und ideologiekritischen Entheroisierung, seine Präsentation einer Phase der politischen Opposition in Deutschland wird mit Mitteln des action-Films entfaltet. Petzolds Film dagegen zeigt die Folgen dieser Bewegung in der für die „Berliner Schule" typischen Konzentration auf das Private.
