Machine learning based obstacle detection for Automatic Train Pairing

Short Range wireless devices are becoming more and more popular for ubiquitous sensor and actuator connectivity in industrial communication scenarios. Apart from communication-only scenarios, there are also mission-critical use cases where the distance between the two communicating nodes needs to be determined precisely. Applications such as Automatic Guided Vehicles (AGV's), Automatic Train Pairing additionally require the devices to scan the environment and detect any potential humans/obstacles. Ultra-Wide Band (UWB) has emerged as a promising candidate for Real-Time Ranging and Localization (RTRL) due to advantages such as large channel capacity, better co-existence with legacy systems due to low transmit power, better performance in multipath environments etc. In this paper, we evaluate the performance of a UWB COTS device — TimeDomain P440 which can operate as a ranging radio and a monostatic radar simultaneously. To this end, we evaluate the possibility of using Supervised Learning based estimators for predicting the presence of obstacles by constructing a multiclass hypothesis. Simulation results show that the Ensemble tree based methods are able to calculate the likelihood of obstacle collision with accuracies close to 95%.
Salen-manganese complexes are superoxide dismutase-mimics.

Complexes of manganese have previously been shown to exhibit SOD activity. In this study, we tested the ability of several (salen)-manganese complexes to scavenge O2. Both neutral and cationic complexes were determined to be SOD-mimics. The activity of the complexes was not affected by the presence of bovine serum albumin in the assay. For most compounds, the activity was inhibited by the addition of EDTA. The stability and high catalytic activity of some of these molecules suggest that they might have potential use in a variety of conditions which involve overproduction of oxygen free radicals.
Linking Folksonomies and Ontologies for Supporting Knowledge Sharing: a State of the Art

Social tagging systems have recently become very popular as a means to classify large sets of resources shared among on-line communities over the social Web. However, the folksonomies resulting from the use of these systems revealed limitations: tags are ambiguous and their spelling may vary, and folksonomies are difficult to exploit in order to retrieve or exchange information. This report compares the recent attempts to overcome these limitations and to support the use of folksonomies with formal languages and ontologies from the Semantic Web.
Motion planning and open loop control design for linear distributed parameter systems with lumped controls

Motion planning and open loop boundary control schemes for linear spatially one dimensional distributed parameter systems with lumped control are discussed. Using Mikusiński's operational calculus the models are formulated as ordinary (operational) boundary value problems. Their solutions are parameterized by introducing a so-called basic variable as an appropriate free parameter. Particular classes of models considered lead to series representations involving derivatives of the basic variable of arbitrary order or to convolution operators which can be interpreted as distributed delays and advances. Examples of bending motions on a ring-shaped plate and a heat exchanger illustrate the results.
Variability of Haemoglobin Estimation Methods in Capillary and Venous Blood of Adult Anemic Patients .

Introduction: Hemoglobin (Hb) assessments is the most reliable indicator widely used to screen individuals for anemia and to evaluate responses to nutritional interventions. Determination of hemoglobin concentration for anemia assessment is among the most frequently performed laboratory tests in inpatient and outpatient care. Method: Adult 78 clinically suspected anemic patients (42 non pregnant female and 36 male) had hemoglobin estimation done. The capillary and venous blood samples of same patients were tested by Haemiglobincyanide (HiCN) method using Drabkin's procedure and Sahli's method for haemoglobin. Drabkin's HiCN method in venous blood was considered as the standard reference method. Result: The mean hemoglobin concentration was found highest by Drabkin's HiCN method in venous blood i.e. 10.5 gm/dl. The coefficient of variation was lowest for the using venous blood in Drabkin's HiCN method i.e. 12.4% and highest for the Sahli's method of capillary blood i.e. 22.8%. Lower correlation coefficient was noted of reference method with the Sahli's capillary and venous blood. Statistically significant (p<0.001) difference in the proportion of patients grades of anemia was noted in between the two methods. Conclusion: Sahli's method had higher coefficient of variability and lower haemoglobin estimation in the capillary and venous blood compared to the reference method.
Cardiovascular autonomic dysfunction and hemodynamic response to anesthetic induction in patients with coronary artery disease and diabetes mellitus.

UNLABELLED Autonomic neuropathy is a major complication of diabetes mellitus and is reported to be associated with increased perioperative hemodynamic instability. We investigated the relationship between autonomic dysfunction and hemodynamic response to anesthetic induction in diabetic and nondiabetic patients with coronary artery disease. We studied 60 patients scheduled for coronary artery surgery, 30 suffering from diabetes mellitus. Preoperative evaluation included traditional cardiovascular autonomic function tests (coefficient of variation of 150 beat-to-beat intervals in heart rate at rest, heart rate response to deep breathing, and heart rate and arterial blood pressure response to standing), spectral analysis of blood pressure and heart rate variability (HRV), and the computation of spontaneous baroreflex sensitivity. After premedication with clorazepate, anesthesia was induced with sufentanil (0.5 microg/kg), etomidate (0.1-0.2 mg/kg), and vecuronium (0.1 mg/kg). Heart rate and blood pressure before anesthetic induction and before and after tracheal intubation were compared between groups. Autonomic function tests, spectral analysis of HRV, and spontaneous baroreflex sensitivity revealed significant differences between patient groups. Most diabetic patients (n = 23) had one or more abnormal test results, in contrast to most nondiabetic patients, who did not show signs of autonomic neuropathy (n = 23). There was no relationship between cardiovascular autonomic function and hemodynamic behavior during anesthetic induction. The blood pressure response to anesthetic induction was not different between patient groups, even when comparing the subgroups with and without abnormal autonomic function tests. These findings indicate that increased hemodynamic instability during anesthetic induction is not obligatory in patients with diabetes mellitus and autonomic dysfunction. IMPLICATIONS This study indicates that increased hemodynamic instability during anesthetic induction is not obligatory in patients with coronary artery disease and autonomic dysfunction.

Transcriptional regulation of a promoter in the men gene cluster of Bacillus subtilis

The control of men gene expression during growth and sporulation of Bacillus subtilis was examined at the transcriptional level. Two different approaches were used. (i) Steady-state levels of men-specific mRNA were measured directly. (ii) A men'-lacZ gene fusion was constructed. In both cases, it was observed that men promoter activity was maximal at the onset of sporulation and declined soon thereafter. These kinetics were similar to the pattern of menaquinone accumulation previously observed. Expression from the men promoter was independent of the presence of the products of the spo0A and spo0H genes and was enhanced by addition of glucose and glutamine to the culture medium. DNA sequence analysis of the promoter region revealed a potential recognition site for the principal vegetative form of RNA polymerase but not for any of the known minor polymerase forms. The functionality in vivo of the promoter sequence was confirmed by high-resolution S1 nuclease mapping of the transcript start site. An additional sequence element was identified that is shared by the sdhA, citG, and ctaA promoters and may indicate a common regulatory mechanism in the expression of these genes.
Architectural characteristics of vastus lateralis muscle and jump performance in young men

Summary Muscle architecture describes the geometric design of a muscle. It will have a great influence in the force generating capacity and the shortening velocity of skeletal muscle. The purpose of the present study was to investigate the relationship between architectural characteristics of one leg muscle and jump performance in a group of physical education students. Ten male students of physical education volunteered for the study. They were tested for their dynamic explosive force by asking them to perform jump tests on a force platform. Skeletal muscle architecture of vastus lateralis was visualized using ultrasonography and their body composition was evaluated. Isolated muscle thickness and fascicle pennation angle of vastus lateralis were measured in vivo, and fascicle length was estimated, using the ultrasonographer.
Deformation monitoring using Sentinel-1 SAR data

Satellite earth observation enables the monitoring of different types of natural hazards, contributing to the mitigation of their fatal consequences. In this paper, satellite Synthetic Aperture Radar (SAR) images are used to derive terrain deformation measurements. The images acquired with the ESA satellites Sentinel-1 are used. In order to fully exploit these images, two different approaches to Persistent Scatterer Interferometry (PSI) are used, depending on the characteristics of the study area and the available images. The main processing steps of the two methods, i.e.; the simplified and the full PSI approach, are described and applied over an area of 7500 km2 located in Catalonia (Spain). The deformation velocity map and deformation time series are analysed in the last section of the paper.
VO 2 max Changes in English Futsal Players after a 6-Week Period of Specific Small-Sided Games Training

Futsal is a high-intensity, intermittent sport where accelerations and short sprints are performed at maximal or sub-maximal intensity. These efforts are interspersed by brief recovery periods, during 2 halves of 20 minutes stopping clock. Aerobic endurance inevitably plays a key role in the players’ performance. The aim of this study was to analyse the VO2 max progression and the agility (with and without ball) of English futsal players during a 6-week period of small-sided games practice. Two teams volunteered to participate in this study; an experimental group (EG), which performed a specialised small-sided training regime and a control group (CG) (normal training regime). VO2max was estimated from the results of the 20-metre Multi-Stage Fitness Test. The VO2max of the futsal players in the EG improved significantly (58.73±2.41 ml/kg/min vs. 60.11 ± 2.99 ml/kg/min, p=0.04). The same player's agility and agility with ball performance did not report any significant changes in either group. The results showed that periodisation, training sessions and methods based on small-sided games, which implied a change in the number of players, the size of the pitch and the task constraints, were adequate to increase aerobic endurance.
A new spectral Polak-Ribière-Polyak conjugate gradient method

By combining the spectral gradient and Polak-Ribière-Polyak (PRP) methods, a new spectral PRP conjugate gradient method is proposed to solve large-scaled unconstrained optimization problems. The method satisfies the famous conjugacy condition: dT k yk−1 = 0, independent of any line search. The direction at each iteration generated by the proposed method is downward for the general objective function without any line search. Under the standard Wolfe line search, we prove that the proposed method is globally convergent. Finally, the proposed method is compared with the PRP method and the scaled PRP method using a classical set of problems.
Face aging effect simulation model based on multilayer representation and shearlet transform

Abstract. In order to extract detailed facial features, we build a face aging effect simulation model based on multilayer representation and shearlet transform. The face is divided into three layers: the global layer of the face, the local features layer, and texture layer, which separately establishes the aging model. First, the training samples are classified according to different age groups, and we use active appearance model (AAM) at the global level to obtain facial features. The regression equations of shape and texture with age are obtained by fitting the support vector machine regression, which is based on the radial basis function. We use AAM to simulate the aging of facial organs. Then, for the texture detail layer, we acquire the significant high-frequency characteristic components of the face by using the multiscale shearlet transform. Finally, we get the last simulated aging images of the human face by the fusion algorithm. Experiments are carried out on the FG-NET dataset, and the experimental results show that the simulated face images have less differences from the original image and have a good face aging simulation effect.
Classifying Customers According to NPS Index: Cluster Analysis for Contact Center Services

The purpose of the study was to discover if, according to the assessment of contact center services quality: (1) customers using contact center services can be grouped into few homogenous items (clusters), (2) if the identified groups cover the classification proposed in the Net Promoter Score (NPS) marketing index (Reichheld, 2003) and (3) which customers belong to each of the clusters, i. e. what is a characteristic of each of the clusters. In the paper, values of observable variables describing service quality in contact centers were measured on a sample of 1 000 contact centers customers. The results of the research are of both cognitive and utilitarian character. The first explain the structure of groups (clusters) joining contact centers customers on a basis of their perception of the quality of contact centers services and some descriptive attributes. The second, by specifying characteristics of different groups of customers, can be used to design contact centers services with a special attention paid to the matters of quality to fully meet these customers’ expectations. The results of the research make the behavior of contact centers customers and their perception of the service quality more comprehensible. So the paper contributes into the development of the methods of classifying customers’ loyalty on a basis of measuring their perception of quality of services delivered through a distant interface. JEL Classification Code: C38, M31.
Networking with multi‐service GEO satellites: cross‐layer approaches for bandwidth allocation

Cross‐layer Radio Resource Management (CL‐RRM) has been recently investigated by quite a few research groups in wireless communications. In the specific satellite‐networking environment, the paper presents an overview of different CL‐RRM techniques devoted to dynamic bandwidth allocation, whose interactions span the physical, data link, network and transport layers, in various combinations. A multi‐service setting is considered, in the presence of variations in both traffic and channel conditions. Regarding the latter, bit and coding rate adaptation are adopted as fade countermeasure, and their effect on the higher layers is modelled as a bandwidth reduction. Traffic models and methodologies for dynamic bandwidth allocation and performance optimization are discussed. Numerical examples are presented to highlight throughput/fairness trade‐offs for long‐lived TCP connections that share multiple channels with different fading depth.

Reliability and Objectivity of Accounting Measurements

ACCOUNTING is a measurement system which is plagued by the existence of alternative measurement methods. For many years, accountants have been searching for criteria which can be used to choose the best measurement alternative. Generally, it is conceded by most accountants that the purpose for which the data are to be used (usefulness) is an important criterion to be considered in the choice of accounting method. ' However, the use or purpose of the data still leaves much to be desired as a criterion since different accounting measurement methods are frequently suggested as being appropriate for a single user or group of users having the same purpose. For example, in a roundtable discussion on "The Measurement of Property, Plant, and Equipment in Financial Statements" the participants agreed that usefulness would be one of the criteria for evaluating different accounting measurement methods. This general criterion " . was applied in the sense of usefulness to investors who are willing and competent to read financial statements carefully and with discrimination for the purposes of assistance in arriving at rational investment decisions. "I In the above statement, the user group and the purpose for which data will be used are both clearly identified. Yet, according to the moderator and reporter, three alternative measurement methods (for fixed asset accounting) represented by three different groups emerged from the discussion. One group would continue to use historical cost. "Some advocates of historical cost will continue to hold to this view unless they are given convincing evidence that an alternative will produce markedly more useful results. "3 A second group favored retention of historical cost, supplemented with statements where the data have been adjusted for general price-level changes. Yet a third group believed that in certain situations acquisition cost should be replaced with a market value or a specific price-index measurement in order to reflect changes in specific prices and assets. Well-informed accountants and businessmen presumably disagree on what is the most useful measurement method even after the purpose for which the data are to be used and the user group are specified. When this happens, the use or purpose of the data is simply too broad and general a criterion to be of much help.
Construction and Validation of an Ego Integrity Status Interview

Erikson's theory regarding the existence of an Ego Integrity versus Despair crisis in old age was tested using an interview derived from Whitbourne and Weinstock's application of Marcia's status construct to the ego integrity crisis. Four integrity statuses were defined: integrity achieving, dissonant (in crisis), foreclosed (avoiding crisis), and despairing. These statuses were reliably (80%) identified among forty elderly community-dwelling men and women through the forty-five-minute semistructured interview. Moreover, predicted differences among the four statuses were observed on questionnaire measures assessing reminiscing activity, death attitudes and preparation, psychological well-being, and questionnaire scales of Stages 6 through 8 of Erikson's theory. The pattern of differences suggested that integrity achieving and foreclosed samples differed mainly regarding their degree of introspection regarding the past, but that both appeared to have a high degree of psychological well-being. Dissonant individuals appeared to be unhappy and stressed, but this was seen as a temporary state in contrast to the more chronic nature of the despairing's low sense of psychological well-being. The validity of the integrity status construct and the interview designed to measure it have, therefore, been supported, and provide the basis for suggested refinements within Erikson's description of the Ego Integrity versus Despair stage.
ACPR Performance Study for Modified LINC Amplifier

A study for the adjacent channel power ratio (ACPR) for modified linear amplification using nonlinear component (LINC) power amplifiers used in wireless communication systems when branch signals are digitally baseband filtered is proposed. The LINC is modified by sending the filtered branch signals and then combine them at the receiver. The IEEE802.11g standard, which operates at 2.4 GHz, employing the OFDM signals is used to show the system performance compatibility with the standard and efficiency improvements. Results show that the ACPR is lowered when using a least square filter, from -26.1dBc to -63.8dBc. The efficiency is improved by 3.4 times when compared with that of a regular LINC.
