Security and Surveillance System for Drivers Based on User Profile and learning systems for Face Recognition

Despite the large and spectacular development in the field of vehicle safety, particularly in the context of driver safety needs, solutions remain insufficient and independent. In this paper, we propose a new system that has been dubbed 3SD "Security and Surveillance System for Drivers". It is a multifunction system as a complete package based on intelligent sensors and cameras that constantly monitor the vehicle's environment and the behavior of the driver to detect early so potentially dangerous situations. In critical driving situations, these systems alert and actively help the driver; if necessary, they automatically intervene to prevent or mitigate the consequences of an accident. The package proposed includes an application comprising a set of pre-registered drivers in a specialized social network interconnected to a geolocation server for distributed real-time sharing of information and data useful for security and traffic. The system is based mainly on learning systems for face recognition based on advanced algorithms Viola and Jones, PCA and management of drivers profiles based on preferences to provide the following features: early detection of sleep, unconsciousness and poor driver behavior, security against theft of vehicles, driver comfort and control and sharing of traffic information in real time between the conductors.
Research on application of compressed sensing based on signal decomposition

Based on compressed sensing (CS) theory and its classical OMP reconstruction algorithm, as to the problems that large storage of measurement matrix is needed when sampling and calculating the whole signal which has a large amount of data and that a huge amount of time is consumed when reconstructing it, we can decompose the signal into many sub-signals through a certain way, and then measure and reconstruct the sub-signals. Finally, we can realize the processing of the whole segment signal. As above, the application of compressed sensing which based on signal decomposition can be called decomposed compressed sensing method in this paper. Currently, a commonly used decomposed compressed sensing method is segmented compressed sensing (SCS). For the problem that there are errors in processing certain types of sparse signals by SCS method, we propose a new decomposed compressed sensing in this paper. The simulation results show that, compared with SCS, the new method can improve the reconstruction efficiency to a certain extent. At the same time, this method is applicable to any type of signal, which has wider application range.
Centre-specific multichannel electrogastrographic testing utilizing wavelet-based decomposition

Although the principles of electrogastrography (EGG) have been known for years, the clinical utility of EGG has not been clearly demonstrated, and EGG recording and analysis techniques have not been fully standardized. The aim of this study was to develop a multichannel EGG technique for detecting abnormal gastric motility using an EGG database specifically designed for a particular testing centre, maximizing the sensitivity and the specificity of the test. Eight healthy volunteers formed a reference group to which 4 study groups (17 gastro-oesophageal reflux disease (GORD) patients, 7 functional dyspepsia patients, 8 post-fundoplication patients and 12 healthy volunteers) were compared. Eight-channel EGG was recorded in the postprandial and fasting states for 30 min each. The recorded signals were wavelet compressed and the resulting error (per cent root mean square difference (PRD)) after the compression was utilized to compare the study groups to the reference group. A threshold in the number of channels with significantly different PRD values was introduced. Sensitivity (SE), specificity (SP) and correct classification rate (CC) of the test in recognizing each clinical condition in the study groups for several channel thresholds and compressions were calculated, and were maximized. Increasing the compression and channel threshold levels improved the specificity, but decreased the sensitivity of the multichannel EGG test. An optimal combination region was identified based on a centre-specific adjustment of the channel threshold and the wavelet compression. The achieved maximum sensitivity, specificity and correct classification for this region in our test centre were as follows: GORD—SE 82.4%, SP 83.3%, CC 82.8%; functional dyspepsia—SE 100%, SP 75%, CC 84.2%; post-fundoplication—SE 75.0%, SP 83.3%, CC 80.0%. The utilization of a wavelet-based decomposition technique to process multichannel EGG signals can be a very effective method for enhancing the clinical utility of EGG, provided it is specifically developed for a given testing centre.
Integrated pharmacokinetic, pharmacodynamic and immunogenicity profiling of an anti-CCL21 monoclonal antibody in cynomolgus monkeys

QBP359 is an IgG1 human monoclonal antibody that binds with high affinity to human CCL21, a chemokine hypothesized to play a role in inflammatory disease conditions through activation of resident CCR7-expressing fibroblasts/myofibroblasts. The pharmacokinetics (PK) and pharmacodynamics (PD) of QBP359 in non-human primates were characterized through an integrated approach, combining PK, PD, immunogenicity, immunohistochemistry (IHC) and tissue profiling data from single- and multiple-dose experiments in cynomolgus monkeys. When compared with regular immunoglobulin typical kinetics, faster drug clearance was observed in serum following intravenous administration of 10 mg/kg and 50 mg/kg of QBP359. We have shown by means of PK/PD modeling that clearance of mAb-ligand complex is the most likely explanation for the rapid clearance of QBP359 in cynomolgus monkey. IHC and liquid chromatography mass spectrometry data suggested a high turnover and synthesis rate of CCL21 in tissues. Although lymphoid tissue was expected to accumulate drug due to the high levels of CCL21 present, bioavailability following subcutaneous administration in monkeys was 52%. In human disease states, where CCL21 expression is believed to be expressed at 10-fold higher concentrations compared with cynomolgus monkeys, the PK/PD model of QBP359 and its binding to CCL21 suggested that very large doses requiring frequent administration of mAb would be required to maintain suppression of CCL21 in the clinical setting. This highlights the difficulty in targeting soluble proteins with high synthesis rates.
Optimization study of advanced modulation formats for 10-Gb/s metropolitan networks

A detailed study of alternative modulation formats appropriate for 10-Gb/s wavelength-division-multiplexing metropolitan area networks is performed to evaluate their tolerance to linear impairments such as optical-signal-to-noise-ratio degradation, dispersion, filter concatenation, interband/intraband crosstalk, as well as their interplay. Point-to-point links and optical add-drop multiplexer chain and ring architectures are investigated, and optimum design parameters are obtained. Through extensive sets of simulation results, it is shown that some of these formats are very tolerant to linear impairments when compared with conventional nonreturn to zero.
Molecular epidemiology of drug resistance markers of Plasmodium falciparum malaria in Thailand

To determine differences in the distribution of drug resistance mutations in the Plasmodium falciparum chloroquine resistance transporter (pfcrt) and P. falciparum multi‐drug resistance 1 (pfmdr1) genes of P. falciparum isolates in Thailand, a study was conducted using polymerase chain reaction‐restriction fragment length polymorphism to detect mutations in P. falciparum isolates obtained from three areas with different levels of in vivo mefloquine (MQ) resistance. All isolates carried mutant allele T76 of the pfcrt gene and wild‐type allele D1246 of the pfmdr1 gene except for one isolate, which showed the wild‐type K76 allele. This isolate was obtained from Chanthaburi Province, an area with high MQ resistance. Relatively low rates of the mutant alleles D1042 and Y86 of the pfmdr1 gene were found among Thai isolates of P. falciparum. However, a statistically significant difference in the distribution was noted. Most of the mutant isolates were found among isolates from areas with moderate or low MQ resistance. Only one isolate with mixed mutant and wild‐type N1042 and D1042 and two mutants of Y86 were found among the isolates from areas with high MQ resistance. The findings provide limited support for the hypothesis that mutant alleles of pfmdr1 may be associated with increased sensitivity to MQ.
Research on an axially slotted cylinder antenna coated with plasma sheath

For radiation characteristics research on antenna coated with a plasma sheath, an axially slotted cylinder antenna is presented. The proposed antenna is composed of a narrow slot cut in the wall of a hollow circular cylinder. The working band width is about 200 MHz. The plasma sheath media was simulated with laminate medium given by drude dispersion model. The electron density in layered plasma model is presented following experimental data. According to the simulation results, return loss deteriorates seriously when thickness of plasma sheath is thickened. And the radiation patterns are mainly in opposition with the plasma sheath when thickness of plasma sheath is 25 mm due to the plasma sheath reflection. The theory analysis and simulation results are presented.
Space charge trapping in electrical potential well caused by permanent and induced dipoles

Space charge formation in low-density polyethylene film containing a small amount of MgO nanoparticles (LDPE/MgO nanocomposite film) subjected to a high electric field greater than 100 kV/mm has been studied using an improved pulsed electroacoustic (PEA) system. No marked space charge formation was observed in LDPE/MgO nanocomposite films. To discuss the mechanism of no space charge accumulation in LDPE/MgO nonocomposite film, we assumed that both electric potential wells produced by a permanent dipole moment such as that of a carbonyl radical (C=0) and an induced dipole consisting of MgO nanoparticles (spherical dielectrics) under a high electric field create a trapping site for electric charge carriers. The trapping depth created by the permanent dipole moment such as that of the carbonyl radical (C=0) of chemical impurity defects is about 0.45 eV. However, that induced by high-permittivity dielectric nanoparticles is about 1.5 to 5.0 eV, which is much deeper than that of chemical impurity defects. The suppression of space charge formation is explained using the potential well model consisting of an induced dipole by a high-permittivity dielectric nanoparticle.
HLA class II genotypes in Mexican Mestizo patients with myasthenia gravis

Myasthenia gravis is an autoimmune, heterogeneous disorder, characterized by the presence of antibodies against acetylcholine receptors at the neuromuscular junction. There is a strong evidence that an individual's genetic composition is an important predisposing factor for the development of the disease. To correlate HLA class II genotypes with thymic pathology in Mexican Mestizo patients who had been subjected to thymectomy. HLA class II genes were analyzed in 60 patients and in 99 healthy ethnically matched controls. Thymic hyperplasia, atrophy, thymoma, and normal histology were encountered in 56, 33, 8 and 2% of patients, respectively. HLA‐DR11 was significantly increased in patients with thymoma compared with healthy controls (pC = 0.001, OR = 13.35, 95% CI 3.5–51.3), compared with the subgroup of hyperplasia patients (pC = 0.005, OR = 15.5, 95% CI 2.78–95.58) and with the atrophy subgroup (pC = 0.04, OR = 10.5, 95% CI 1.75–70.95). This study provides the evidence of an association between HLA class II alleles with clinical and genetic heterogeneity in myasthenia gravis, particularly in those with thymoma (HLA‐DR11).
A nonparametric Bayesian approach to inference for non-homogeneous Poisson processes

We propose modeling for Poisson processes over time, exploiting the connection of the Poisson process intensity with a density function. Nonparametric mixture models for this density induce flexible prior models for the intensity function. We work with Beta densities for the mixture kernel and a Dirichlet process prior for the mixing distribution. We also discuss modeling for monotone intensity functions through scale uniform mixtures. Simulation-based model fitting enables posterior inference for any feature of the Poisson process that might be of interest. A data example illustrates the methodology.
Automatic verification of refinement

Given two models of a circuit, Q and Q', we say that Q' as a refinement of Q if every possible behavior of Q' is allowed by Q. We present a unified framework for verifying refinement using both model-checking and symbolic trajectory evaluation techniques. In this framework, the refinement conditions are derived and verified automatically. To demonstrate this approach, we present a design for a synchronizer circuit used in a high-speed synchronous design. <<ETX>>
LiDAR-based 2D Localization and Mapping System using Elliptical Distance Correction Models for UAV Wind Turbine Blade Inspection

: The wind energy sector faces a constant need for annual inspections of wind turbine blades for damage, erosion and cracks. These inspections are an important part of the wind turbine life cycle and can be very costly and hazardous to specialists. This has led to the use of automated drone inspections and the need for accurate, robust and inexpensive systems for localization of drones relative to the wing. Due to the lack of visual and geometrical features on the wind turbine blade, conventional SLAM algorithms have a limited use. We propose a cost-effective, easy to implement and extend system for on-site outdoor localization and mapping in low feature environment using the inexpensive RPLIDAR and an 9-DOF IMU. Our algorithm geometrically simpliﬁes the wind turbine blade 2D cross-section to an elliptical model and uses it for distance and shape correction. We show that the proposed algorithm gives localization error between 1 and 20 cm depending on the position of the LiDAR compared to the blade and a maximum mapping error of 4 cm at distances between 1.5 and 3 meters from the blade. These results are satisfactory for positioning and capturing the overall shape of the blade.
Flanking Region of the Parathyroid Hormone Gene Mediates Negative Regulation by 1 , 25-( OH ) a Vitamin D 3 *

To study the effects of 1,25-(OH), vitamin DS on the transcription of the human parathyroid hormone (PTH) gene, 684 base pairs of the 5‘-flanking portion of the human PTH gene were fused to the bacterial neo gene. The fusion gene was transfected into rat pituitary cells, and mixed populations of colonies were selected using the neomycin analog, G418. The level of RNA initiated from the human PTH gene promoter region in these cells was suppressed by 1,25-(OH), vitamin D,. Synthesis of the same transcript under control of a viral promoter was not regulated by 1,225(OH), vitamin D,. The effect of 1,25-(OH), vitamin DS was detected within 24 h at physiologic doses of 1,25(OH), vitamin D,, and was not influenced by addition of cycloheximide. Thus 1,25-(OH), vitamin DS acts on the 5”flanking portion of the PTH gene to decrease the rate of transcription by a mechanism that requires no new protein synthesis.
Policy-Based Diffserv on Internet Servers: The AIX Approach (On the Wire)

The Internet infrastructure must evolve from best-effort service to meet the needs of different customers and applications. With Internet traffic differentiation, service providers can support a range of offerings, such as loss or delay bounds and network bandwidth allocation, to meet different performance requirements. The differentiated services (Diffserv) architecture provides a scalable approach, in which network access (or edge) devices aggregate traffic flows onto provisioned pipes that traverse a streamlined network core. We have identified the key requirements for provisioning Diffserv functions on Internet servers. Based on these requirements, we have implemented, and deployed, a policy-based architecture on IBM's AIX operating system that provides Diffserv services to both QoS-aware and -unaware applications.
The Optimization of Queries in Relational Databases

A fully implemented system for optimizing and executing queries for relational databases is described. The system optimizes n-table, equi-join queries written in QUEL, the query language supported by the INGRES relational database management system (DBMS). Tenfold and greater improvements in response time to complex queries have been achieved compared to INGRES. The system models query execution plans as binary trees where each node can be one of four operator types: join, restrict-project, reformat and disk-resident-scan. This model is shown to include many previously published algorithms in addition to many new ones. The system also uses histograms to represent information about attribute's distributions. This information is used to accurately determine query execution cost and results in queries which run approximately thirty percent faster than when the distributional information is not used (i.e., uniform distributions are assumed). Measurements are given comparing execution times for the new system and INGRES, comparing estimated and actual disk I/O with actual query execution time, and comparing the use of accurate distributional information stored in histograms with the use of uniform distributions.
Pulsed CO/sub 2/ laser ablation of tissue: effect of mechanical properties

The ablation rate of guinea pig skin and bovine aorta, myocardium, and liver by a CO/sub 2/ laser emitting 2- mu s-long pulses was quantified. Ablation efficiency was found to be strongly dependent on the ultimate tensile strength of the tissue; the ablation efficiency of liver is seven times that of skin. Gluteraldehyde cross linking of skin, which is known to greatly increase tissue stiffness but not significantly affect ultimate tensile strength, did not change the ablation rate. The water content of the tissues, which largely determines the optical and thermal properties, was measured and found to vary only slightly. The results demonstrate that tissue mechanical properties are important in the interpretation and modeling of pulsed laser ablation of tissue and that variations in these mechanical properties can lead to drastically different cutting rates for different tissues. <<ETX>>
Graz University of Technology at CL-SciSumm 2017: Query Generation Strategies

In this report we present our contribution to the 3rd Computational Linguistics Scientific Document Summarization Shared Task (CL-SciSumm 2017), which poses the challenge of identifying the spans of text in a reference paper (RP) that most accurately reflect a citation (i.e. citance) from another document to the RP. In our approach, we address this challenge by applying techniques from the field of information retrieval. Therefore we create a separate index for every RP and then transform each citance to a RP into a query. This query is subsequently used to retrieve the most relevant spans of text from the RP. Different ranking models and query generation strategies have been employed to alter which spans of text are retrieved from the index. Furthermore we implemented a k-nn classification based on our search infrastructure for assigning the cited text span to pre-defined classes.
The “Vertical” Generalization of the Binary Goldbach’s Conjecture as Applied on “Iterative” Primes with (Recursive) Prime Indexes (i-primeths)

This article proposes a synthesized classification of some Goldbach-like conjectures, including those which are “stronger” than the Binary Goldbach’s Conjecture (BGC) and launches a new generalization of BGC briefly called “the Vertical Binary Goldbach’s Conjecture” (VBGC), which is essentially a metaconjecture, as VBGC states an infinite number of conjectures stronger than BGC, which all apply on “iterative” primes with recursive prime indexes (i-primeths).
Towards structured representation of academic search results

Searching for scientific publications is a tedious task, especially when exploring an unfamiliar domain. Typical scholarly search engines produce lengthy unstructured result lists, which are difficult to comprehend, interpret and browse.An informative visual summary could convey useful information about the returned results as a whole, without the need to sift through individual publications.The first contribution of this thesis is a novel method of representing academic search results with concise and informative topic maps. The method consists of two steps: i) extracting interrelated topics from the publication titles and abstracts, and ii) summarizing the resulting topic graph. In the first step we map the returned publications to articles and categories of Wikipedia, constructing a graph of relevant topics with hierarchical relations. In the second step we sequentially build a summary of the topic graph that represents the search results in the most informative way. We rely on sequential prediction to automatically learn to build informative summaries from examples. The summarized topic maps share the most of the benefits and avoid most of the drawbacks of the current methods for grouping documents, such as clustering, topic models, and predefined taxonomies. Specifically, the topic maps are dynamic, fine-grained, of flexible granularity, with up-to-date topics connected with informative relations and having meaningful concise labels. The second contribution of this thesis is a method for bootstrapping domain-specific ontologies from the categories of Wikipedia. The method performs three steps: i) selecting the set of categories relevant to the domain, ii) classifying the categories into classes and individuals, and iii) classifying the sub-category relations into ``subclass-of'', ``instance-of'', ``part-of'' and ``related-to''. In each step we rely on binary classification, which makes the method flexible and easily extensible with new features. For the purpose of academic search, the proposed method advances the creation of semantically rich topic maps. In general, the method semi-automates the construction of large-scale domain ontologies, benefiting multiple potential applications. Providing ground truth data for structured prediction of large objects, such as topic map summaries or domain ontologies, is tedious. The last contribution of this thesis is an initial investigation into reducing the labeling effort in structured prediction tasks. First, we present a labeling interface that suggests topics to be added to the ground truth topic map summary. We modify a state of the art sequential prediction method to iteratively learn from the summaries one topic at a time, while retaining the convergence guarantees. Second, we present an interactive learning method for selecting the categories of Wikipedia relevant to a given domain. The method reduces the number of required labels by actively selecting the queries to the annotator and learning one label at a time.
Improved thermal stability of In/sub 0.53/Ga/sub 0.47/As metal-semiconductor-metal photodetectors with Al/sub 2/O/sub 3/ interfacial layer

The thermal stability of In/sub 0.53/Ga/sub 0.47/As metal-semiconductor-metal photodetectors has been improved by using thin electron-beam evaporated Al/sub 2/O/sub 3/ interfacial layers of different thickness. The addition of the interfacial layer allows for an increase in anneal temperature from 250/spl deg/ to 350/spl deg/C with a four-fold dark current increase. Measurements of impulse responses at 1.3 /spl mu/m showed, that the frequency behaviour is not adversely affected by the increased capacitance caused by oxide charges, since metal-semiconductor-metal photodetectors are carrier transit-time limited. <<ETX>>
