AN ANALYSIS OF TRANSACTIONS IN E-PAYMENT SYSTEM USING MOBILE AGENTS

Commercial interactions between merchants and customers pose a significant concern as they are associated with a large volume of data and complex information, especially when there is a need for switching requirements. This paper presents an agent-based analysis of e-payment transactions with the switching operations. The model adopts an inter-bank transaction network and consists of a terminal point of sale (POI) and three essential players in e-payment: customer, bank (merchant), and the Switch. This study analyses the various payment interactions using agent technology. The agent coordinates movement while the negotiation protocol serves as an internal control of the payment agreements, while the interactive hosts are the platforms that determine the status of transactions. Each agent host is equipped with a Certification Authority (CA) to secure communication between the merchant and the customer. Different transactions that agents could make are examined with formal descriptions. The implementation is achieved in Jade and compares with the object serialization mechanism. The simulation results show higher quality adaptation of agent systems and evidence of agentisation of e-transaction with Switch.

Numerical evaluation of the effectiveness of coronary revascularization

In the present paper we construct the model of coronary flow which utilizes the patient’s CT data on both large CA and perfusion. We reconstruct large coronary vessels based on the CT data and extrude possibly invisible vessels from the branches of the left coronary artery so that every terminal point supply every of standardized zone of myocardium. We apply a previously developed and validated 1D model of haemodynamics. Utilizing the patient-specific CTP data for modifying outflow terminal resistance at rest and under stress conditions is the major novelty of the present work. From our results it follows that acceptable values of fractional flow reserve (FFR) after the stenotic treatment may produce false negative output. Therefore healthy FFR values may be observed after ineffective revascularization. We also conclude that microvascular perfusion impairment plays significant role in correct computational estimation of haemodynamic indices before stenotic treatment. The advantage of the presented approach is the availability of transmural perfusion ratio assessment in everyday practice.

Synthesis of a mobile robot spatial stabilization system based on machine learning control by symbolic regression

The spatial stabilization system synthesis problem of the robot is considered. The historical overview of methods and approaches for solving the problem of control synthesis is given. It is shown that the control synthesis problem is the most important task in the field of control, for which there are no universal numerical methods for solving it. As one of the ways to solve this problem, it is proposed to use the method of machine learning based on the application of modern symbolic regression methods. This allows you to build universal algorithms for solving control synthesis problems. Several most promising symbolic regression methods are considered for application in control tasks. The formal statement of the control synthesis problem for its numerical solution is given. Examples of solving problems of synthesis of system of spatial stabilization of mobile robot by method of network operator and variation Cartesian genetic programming are given. The problem required finding one nonlinear feedback function to move the robot from thirty initial conditions to one terminal point. Mathematical records of the obtained control functions are given. Results of simulation of control systems obtained by symbolic regression methods are given.

The past participle and the periphrastic passive construction in French

Our hypothesis is that the past participle is a singular form in the TAM (tense-aspect-mood) linguistic system in French, in that it represents the internal time of the process on its terminal point ([R = Et]). Due to this representation of internal time, the p.p. can be related to the second argument – the patientive argument – of a direct transitive process: it is the essential element of the passive construction. Contrary to what is often written, the copula être ‘be’, is an optional element: it may serve to develop the construction in its periphrastic dimension, but it is not necessary to the passive construction itself, as the cases of the passive in the participial clause demonstrate. Moreover, the p.p. is not intrinsically resultative or processive, no more than it is active or passive: from its aspect [R = Et], it can, in interaction with different contexts, participate in the production of these different effects of meaning in discourse.

Das Präteritum im Alemannischen Südwestdeutschlands

Zusammenfassung This paper analyses the increase in the use of the preterite in spoken Alemannic in south-western Germany. There are almost no recent studies that explore the preterite in Upper German because of the widespread hypothesis that there is no preterite in Upper German (except for the verb sein ‘to be’) due to the loss of the preterite in Upper German (Oberdeutscher Präteritumschwund). In contrast to this, I account for a language change in the timespan from 1974 to 2013 in which the preterite becomes more frequent in relation to the perfect and is now part of the spoken Alemannic in south-western Germany. To account for this, I use a combination of a real time and an apparent time analysis. Additionally, all verbs forming a preterite have a specific semantic value, i. e. an inherent meaning of state. This means they are durative (=the situation lasts for a certain period of time), atelic (=the situation has no terminal point at which the situation is complete) and non-dynamic (=the situation involves no change). Perfect forms on the other hand do not have this specific semantic value.

Determinination of the Frequency of Altered Cardiac Repolarization by Measuring the Heart rate Corrected QT Interval in COPD Patients

Objectives: To determine the frequency of altered cardiac repolarization by measuring the heart rate corrected QT interval in COPD patients. Setting: Department of Medicine at LUMHS hospital Hyderabad/Jamshoro. Study Design: Descriptive Cross sectional study. Duration of Study: 6 months from 01-03-2019 to 31-08-2019. Methods: A total of 232 patients with severe acute exacerbation of COPD were included in this study. A 12 lead ECG was performed. QT intervals were measured on a resting ECG tracing in lead II. The QT interval was measured manually from the starting point of the QRS complex to the terminal point of the down slope of the T wave. Results: A total of 232 patients with COPD were included in this study. Most of the cases were above 50 years of age. The average age of the patients was 53.74±4.35 years. There were 92.67% (215/232) male and 7.33% (17/232) female. Out of 232 patients, 21.14% were current smoker and 75.86% were ex-smoker. A QTc interval >0.44 seconds was considered abnormally prolonged. Frequency of altered cardiac repolarization by measuring the heart rate corrected QT interval in COPD patients was 31.47% (73/232). Rate of altered cardiac repolarization was not significant among different age groups (p=0.641). Rate of altered cardiac repolarization was significantly high in male as compare to female (33.5% vs. 5.9%; p=0.018). This was not significant between obese and non-obese groups (p=0.100). Rate of altered cardiac repolarization was significantly high in former smoker (p=0.0005) and those patients whose duration of COPD was above 15 years (p=0.0005). Conclusion: Patients with hypoxic chronic obstructive pulmonary disease (COPD) have evidence of a subclinical parasympathetic autonomic neuropathy, with apparent preservation of sympathetic function. Measuring heart rate corrected QT interval (QTc) test is repeatable, easy to perform and a sensitive indicator for autonomic dysfunction in breathlessness individuals with COPD.
