Using Network Attached Storage for IP-Surveillance : Bottleneck analysis and developing a method for testing Network Attached Storage performance for IP-surveillance (2013)

IP-surveillance systems are surveillance systems designed to send video and audio over IP-networks, to be able to function a typical system consist of IP-cameras to record footage, a client to view footage and recordings, network hardware to send the data, protocols to administer storage and viewing operations and last but not least a location to store the captured data. One of the options for storing surveillance video is to use a Network Attached Storage. Axis has received customer cases reporting lost footage and cameras losing their connection when using NAS-devices as storage in IP-surveillance systems. This thesis aims to investigate what a NAS is and how it interacts with cameras in an IP-surveillance environment by analyzing the protocols and components being used and by performing experiments to locate the system bottleneck causing these problems. After concluding that the hard disk drive was the bottleneck because of the overload imposed on the other components by the incoming data traffic and how data is moved and temporarily stored in a system. Recommendations of possible ways to remedy these problems were suggested with the proposed problem of solving the bottleneck problem was to add more disks to improve performance, this was the second aim of the thesis, which sadly was not possible because of the 2-bay NAS systems being used in the tests. The third and final aim was to establish and develop method guidelines for testing NAS-systems. This was done by using previous research in the area and using data encountered when trying to locate the bottleneck.
UVM based testbench architecture for unit verification (2014)

In this work, the Universal Verification Methodology (UVM) is analyzed through its application in the development of two testbenches for unit verification. The first one targets a First Input-First Output (FIFO) buffer module and employs all the basic UVM components; a scoreboard with a Reference Model and a Functional Coverage collector are also implemented. The second one verifies an I2C EEPROM slave module; a bus functional model for the I2C protocol is defined to facilitate the driver implementation, rising the level of abstraction and allowing the reuse of the verification component for other I2C devices.
Cesium coherent population trapping magnetometer for cardiosignal detection in an unshielded environment (2007)

We present encouraging results obtained with an experimental apparatus based on coherent population trapping and aimed at detecting a biological (cardiac) magnetic field in a magnetically compensated but unshielded volume. The work includes magnetic-field and magnetic-field-gradient compensation and uses differential detection to cancel common mode magnetic noise. Synchronous data acquisition with a reference (electrocardiographic or pulse-oximetric) signal makes possible improvement of the signal-to-noise ratio in off-line averaging. The setup has the significant advantages of working at room temperature with a small-size head, and the possibility of fast adjustments of the dc bias magnetic field, which makes the sensor suitable for detecting a biomagnetic signal at any orientation with respect to the axis of the head and in any position on the patient's chest, which is not the case with other kinds of magnetometers.
Efficient approximate implementations of the fast affine projection algorithm using orthogonal transforms (2002)

The recently-introduced fast affine projection (FAP) adaptive filter has performance rivalling that of the RLS adaptive filter in many situations. However, the sliding-window RLS algorithm embedded within the FAP adaptive filter can be too complex to implement in some cases. We describe an alternate implementation of the FAP adaptive filter that uses orthogonal transforms to approximately calculate the affine projection. Simulations show that the performance of this simplified algorithm is nearly as good as the original algorithm when the transform is chosen properly. In addition, we provide a gradient step size (GSS) method for enhancing the performance of the FAP adaptive filter in nonstationary signal environments.
Systemic release of chemical signals by herbivore-injured corn. (1992)

Corn seedlings respond to insect herbivore-inflicted injury by releasing relatively large amounts of several characteristic terpenoids and, as a result, become highly attractive to parasitic wasps that attack the herbivores. Chemical evidence showed that the induced emission of volatiles is not limited to the sites of damage but occurs throughout the plant. This evidence was obtained by comparing the release of volatiles from leaves of unharmed (control) seedlings with the release of volatiles from undamaged leaves of seedlings with two injured leaves treated with caterpillar regurgitant. Immediately after injury no differences were measured in the released volatiles, but several hours later the undamaged leaves of injured plants released the terpenoids linalool, (3E)-4,8-dimethyl-1,3,7-nonatriene, and (3E,7E)-4,8,12-trimethyl-1,3,7,11-tridecatetraene in significantly larger amounts than leaves of unharmed plants. Other volatiles that are released by herbivore-injured leaves were detected occasionally only in trace amounts from the undamaged leaves of a damaged seedling. The systemic release of volatiles by injured corn coincided with attractiveness to the parasitoid Cotesia marginiventris; undamaged leaves of injured plants became significantly more attractive than leaves from control seedlings. These findings show conclusively that when a plant is injured by an insect herbivore the whole plant emits chemical signals.
Recent progress in thin‐film cadmium telluride solar cells (1993)

Abstract Cadmium telluride (CdTe) with a room‐temperature bandgap energy of 1.45 eV has been shown to be the most promising low‐cost, thin‐film photovoltaic material for terrestrial applications. Significant progress has been made during the past several years, and thin‐film CdTe solar cells of > 1 cm 2 area with conversion efficiencies higher than 12% have been prepared by several techniques. Thin‐film CdTe photovoltaic modules with 10% efficiency have also been produced. They are of the heterojuntion configuration using a transparent conducting semiconductor (TCS) as the window and p‐CdTe as the absorber. In this paper, the potential window materials for thin‐film CdTe solar cells are discussed. Thus far, cadmium sulphide (CdS) with a bandgap energy of 2.42 eV at room temperature has been found to be best suited for efficient CdTe solar cells. the deposition techniques for p‐CdTe films capable of producing efficient solar cells, including close‐spaced sublimation (CSS), electrodeposition, screen printing and spraying, are briefly reviewed, and the characteristics of the resulting solar cells are discussed. It is concluded that the efficiency of thin‐film CdTe solar cells can be increased to 18‐19% in the near‐term, leading to 15‐16.5% efficient modules.
Positional isomerism of unsaturated fatty acids in the rat quantification of isomeric mixtures (1965)

Abstract Mono‐ and dienoic acids of lipids from rat milk, rat sucklings, and rats on a fat‐deficient diet were investigated. The percentage of uncommon isomers of palmitoleic acid was highest in milk, the newborn and the suckling rats, but receded after weaning. Isomers of linoleic acid were found only in traces in sucklings but became pronounced in rats on diets lacking essential fatty acids. The proportion of 8,11‐diene among octadecadienoic acids increased markedly under such conditions within one week and two additional isomers became prominent after longer periods of fat‐deficient diet. A supplement of hydrogenated coconut fat did not influence the occurrence of these isomers. Dietary petroselinic acid is incorporated by the rat into tissue lipids. 4‐Hexadecenoic and a small amt of 8‐eicosenoic acid arise from it. Quantification of isomeric mixtures by ozonization‐hydrogenation and subsequent gas‐liquid chromatography is discussed in detail.
Manipulation of the Phospholipid Composition of Tissue Culture Cells (1974)

Methods have been devised to significantly alter the phospholipid composition of LM cells grown in serum-free tissue culture medium. The polar head groups of the phospholipids, as well as the acyl groups of these lipids, can be changed. When LM cells were grown in medium containing choline analogues, either N-methyl-ethanolamine or N,N-dimethylethanolamine, or the unnatural analogues, 1-2-amino-1-butanol or 3-amino-1-propanol, up to 50% of the cellular phospholipids contained the analogue supplied. When linoleate was added to the cells as a bovine serum albumin complex, up to 40% of the fatty acids of the phospholipids were linoleate. Under the conditions discussed, the polar head group composition, the fatty acid composition, or both together could be varied in the membrane phospholipids.
Association between autoimmune reactions and severity of atopic dermatitis in children with herpes virus infection (2013)

Our data shown that clinical course of severe AD is accompanied with autoimmune response to epidermal antigens (keratin and elastin). Elevated levels of the autoantibodies, especially against the background of HV infection may be useful serological parameter for monitoring of the disease activity.
Class II Amalgam Restorations, Glass-Ionomer Tunnel Restorations, and Caries Development on Adjacent Tooth Surfaces: A 3-Year Clinical Study (1992)

Eighteen caries-active adolescents, each having both a class II conventional amalgam (Dispersalloy) and a glass-ionomer (Ketac Silver) tunnel restoration of the same age placed on a contralateral tooth, were part of a 3-year clinical study. At the 1- and 2-year examinations all test restorations were assessed as acceptable in all patients. At the 3-year assessment three amalgam restorations failed due to recurrent caries, and one glass-ionomer restoration failed due to marginal ridge fracture. During the entire study period, the requirement of restorative therapy because of primary proximal caries was significantly reduced (p < 0.05) on tooth surfaces adjacent to the glass-ionomer restorations as compared with that on tooth surfaces adjacent to the amalgam restorations.
Detection and characterization of human papillomavirus type 45 DNA in the cervical carcinoma cell line MS751. (1997)

The cervical carcinoma-derived cell line MS751 was examined for human papillomavirus (HPV) DNA and RNA. A genomic fragment containing both viral and cellular sequences was cloned. Sequence analysis showed that MS751 cells contain a partially deleted HPV-45 genome integrated at a single chromosomal site. HPV sequences from the E6-E7 region are expressed as poly(A)+ RNA.
MEGOR: Multi-constrained Energy efficient Geographic Opportunistic Routing in Wireless Sensor Network (2017)

Providing better energy efficient network is the important critical issues in Wireless Sensor Networks. We presented Multi-constrained Energy efficient Geographic Opportunistic Routing algorithm that enhance the network lifetime based on efficient Geographic Opportunistic Routing. Geographic Opportunistic Routing algorithm uses single path multi hop routing technique in which packets are effectively routed from source to the sink node in a given geographical region. Proposed algorithm is devised with unique parameters viz., Single hop Packet Progress, Packet Reception Ratio, Residual Energy and Energy Density to select intermediate next nodes to forward the packet to sink node. The MEGOR exhibits better results in terms of delay, reliability, energy efficiency and network lifetime when compared with earlier state_of_art works.
Nouer les fils de la réécriture : une visite interpolée au château du Graal (2004)

L'insertion d'un vers, d'une scène, voire d'un épisode, dans un récit préalable, constitue une forme de réécriture puisque le texte initial est repris et transformé. Une telle insertion peut viser au renforcement de la cohérence narrative et diégétique du texte premier, ou bien modifier la logique du récit. C'est à un exemple du premier type que s'intéresse cet article. En effet, dans certaines versions de la Première Continuation du Conte du Graal, figure un passage « interpolé » qui tente de concilier les scènes chez le Roi Pêcheur que l'on trouve dans le Conte du Graal et dans la version courte de la Première Continuation. Cette insertion offre un exemple de variance intertexuelle dans la mesure où son rédacteur, soucieux d'allier des représentations divergentes, a soigneusement réécrit, en les combinant, les deux intertextes dont il disposait. La présente analyse dégage les procédures de reformulation qu'il emploie, et s'interroge aussi sur les imperfections de sa démarche : toutes les contradictions ne sont pas supprimées et la logique de conciliation impliquée par cette réécriture montre ses failles. L'examen d'une autre insertion, présente dans un manuscrit du Conte du Graal, prouve que l'interpolation relève d'une forme de logique ambiguë.
A Novel Technology For Megabit Density, Low Power, High Speed, NVRAMs (1993)

A novel technology for realizing high density, high performance NVRAMs has been developed. The heart of the technology is a scalable non-volatile memory element which requires low programming voltages. Coupled with a versatile, 0.4/spl mu/m feature size, high speed, BiCMOS SRAM latch a true high performance NVRAM bit cell has been designed.
Time delay estimation (2005)

A maximum likelihood (ML) estimator is derived for determining time delay between two signals observed in the presence of uncorrelated noise, under the assumptions of known signal and noise spectral characteristics. This ML estimator can be realized as a pair of receiver prefilters followed by a cross correlator. The time argument at which the correlator achieves a maximum is the delay estimate. Qualitatively, the role of the prefilters is to weight the signal passed to the correlator according to the strength of the coherence function. Other realizations of the ML processor are also discussed. The variance of a generalized correlation time delay estimator is derived when the estimate is in the neighborhood of the true delay. An example using these results is given with emphasis on the effect of erroneously specifying the frequency weighting to be employed. Limitations of the derived results are also discussed.
Tonotopic Organization of the Auditory Cortex: Pitch Versus Frequency Representation (1989)

According to the place principles of the classical hearing theory, the physical entity frequency is encoded in the auditory periphery as place information (tonotopic representation), which is decoded in more central parts of the auditory system to form the subjective entity pitch. However, this relation is true only for pure-tone signals (spectral pitch); it can be quite different in the case of complex auditory stimuli (virtual pitch), thus requiring a multistage process for pitch formation. Neuromagnetic measurements showed that the tonotopic organization of the primary auditory cortex reflects the pitch rather than the frequency of the stimulus; that is, the pitch formation process must take place in subcortical regions.
A High-Rate, High-Capacity, Nanostructured Sn-Based Anode Prepared Using Sol-Gel Template Synthesis (2001)

Li-ion battery anodes derived from oxides of tin have recently received considerable interest because in principle they can store over twice as much Li as graphite. However, large volume changes occur when Li is inserted and removed from these Sn-based materials, and this causes internal damage to the electrode, resulting in loss of capacity and rechargability. We describe here a new nanostructured -based electrode that has extraordinary rate capabilities, can deliver very high capacities (e.g., >700 mAh at 8 C rate), and still retain the ability to be discharged and recharged through as many as 1400 cycles. These electrodes, prepared via the template method, consist of monodisperse 110 nm diam nanofibers protruding from a current-collector surface like the bristles of a brush. © 2001 The Electrochemical Society.

Polymerase II Promoter Strength Determines Efficacy of microRNA Adapted shRNAs (2011)

Since the discovery of RNAi and microRNAs more than 10 years ago, much research has focused on the development of systems that usurp microRNA pathways to downregulate gene expression in mammalian cells. One of these systems makes use of endogenous microRNA pri-cursors that are expressed from polymerase II promoters where the mature microRNA sequence is replaced by gene specific duplexes that guide RNAi (shRNA-miRs). Although shRNA-miRs are effective in directing target mRNA knockdown and hence reducing protein expression in many cell types, variability of RNAi efficacy in cell lines has been an issue. Here we show that the choice of the polymerase II promoter used to drive shRNA expression is of critical importance to allow effective mRNA target knockdown. We tested the abundance of shRNA-miRs expressed from five different polymerase II promoters in 6 human cell lines and measured their ability to drive target knockdown. We observed a clear positive correlation between promoter strength, siRNA expression levels, and protein target knockdown. Differences in RNAi from the shRNA-miRs expressed from the various promoters were particularly pronounced in immune cells. Our findings have direct implications for the design of shRNA-directed RNAi experiments and the preferred RNAi system to use for each cell type.

In this paper, a foil-based BioMEMS for the electrochemical detection of troponin I, a marker for myocardial infarction is presented.
Decoding algorithms for noncoherent trellis coded modulation (1996)

Noncoherent decoding of trellis codes using multiple-symbol overlapped observations was shown previously to achieve close to the coherent performance. Optimal decoding by the Viterbi algorithm for L-symbol observations requires a number of states which grows exponentially with L. Two novel suboptimal algorithms are presented, for which the number of states is the same as the original code, yielding a complexity depending weakly on L. For practical values of L, both algorithms are substantially less complex than the optimal algorithm. The first algorithm, the basic decision feedback algorithm (BDFA), is a low complexity feedback decoding scheme, based on the Viterbi algorithm. This algorithm is shown to suffer from increased error probability and from error propagation. A slight modification to this algorithm can, in most cases, reduce these effects significantly. The second algorithm uses the BDFA as a basic building block. This algorithm is based on a novel concept called "estimated future" and its performance is very close to optimum for most practical eases with some additional complexity and memory requirements as compared to the first algorithm. Performance analysis and simulation results are also given.
Interface quality and electron transfer at the GaInP on GaAs heterojunction (1998)

Hall measurements performed on Ga0.50In0.50P/In0.20Ga0.80As structures show abnormally low mobility both at room temperature and at 77 K, and too high electron densities which cannot be attributed to a normal two-dimensional electron gas in the channel. On the other hand, low temperature photoluminescence on asymmetrical AlGaAs/GaAs/GaInP quantum wells and x-ray photoemission spectroscopy measurements reveal the presence of arsenic atoms in the GaInP barrier. Using a one-dimensional Schrödinger–Poisson simulation with a nonabrupt interface model, we show that the presence of arsenic in GaInP leads to the formation of a parasitic GaInAsP well between the δ-doped layer and the channel, trapping the main part of transferred electrons. We experimentally show that the electron transfer can be drastically improved by inserting a thin AlInP layer at the interface. Insertion of at least six monolayers of AlInP is needed to recover a normal electron transfer as high as 2.1×1012 cm−2.
Air ultraviolet laser excited by high-power microwave pulses (1988)

Lasing in atmospheric air excited by high-power nanosecond microwave pulses was observed and investigated. Stimulated emission was observed as a result of transitions in N2 at wavelengths λ = 315.8, 337.1, and 357.7 nm and resonator-free amplification of spontaneous radiation. The forward and backward laser fluxes differed by a factor exceeding 10 demonstrating that a traveling wave configuration was established. The optimal air pressure was 38 Torr. In principle, it should be possible to construct a laser using free–localized discharge in air excited by crossing laser beams.
Nonlinear coloration of photochromic spiropyran solutions (1973)

An investigation was made of the two-photon photochromism of spiropyran solutions subjected to ruby laser radiation. The two-photon absorption cross section of spiropyran was calculated. At high laser radiation intensities the dependence of the optical density of the photoinduced form of spiropyran on the incident radiation intensity deviated from the square law. The cause of this deviation was considered.
Green Noise Digital Halftoning With Multiscale Error Diffusion (2010)

Multiscale error diffusion (MED) is superior to conventional error diffusion algorithms as it can eliminate directional hysteresis completely and possesses a good blue noise characteristic. However, due to its filter design, it is not suitable for systems with poor isolated dot generation and instable dot gain. In this paper, we propose a MED algorithm to produce halftones of desirable green noise characteristics. This algorithm allows one to adjust the desirable cluster size freely through a single parameter and supports a linear relationship between the cluster size and the input gray level. With a close-to-isotropic diffusion filter, the algorithm can effectively remove pattern artifacts, eliminate directional artifacts and preserve original image details. Analysis and simulation results show that it provides better performance in terms of various aspects including dot distribution, anisotropy and output image quality as compared with other conventional green noise error diffusion algorithms.
Reinventing the Baltic Sea Region: From the Hansa to the Eu-Strategy of 2009 (2012)

The political changes of 1989 stimulated a new perception and perspective of the Baltic Sea Region. And this gained momentum with the Eastern Enlargement of the EU. The new situation encouraged research as well. In this context the “Baltic Sea” is not an unchangeable physical setting, but also a construction of different actors or protagonists. People and powers continuously reinvent the Baltic Sea Region. That is why; the following paper focuses on the different notions of the Baltic Sea Region from the Middle Ages up to now and also examines the recent EU-Strategy of this region.
Trust-QoS Based Semantic Web Service Discovery Technology (2011)

The discovery of suitable Web services for a given user requirement is one of the key technology in application of web services. A mechanism is proposed to support QoS-based semantic Web service discovery. Firstly to reduce the overhead and enhance the discovery efficiency, genetic algorithm is adopted as a method of service clustering. Furthermore, the evaluation and calculation of QoS was realized to satisfy the user's QoS requirements. In the end, simulation results demonstrated the effectiveness of the proposed method.
