Is "No Trade Theorem" Really A Paradox: Analysis Based On Decision Theory, Laxman Bokati, Vladik Kreinovich

Departmental Technical Reports (CS)

One of the challenges in foundations of finance is the so-called "no trade theorem" paradox: if an expert trader wants to sell some stock, that means that this trader believes that this stock will go down; however, the very fact that another expert trader is willing to buy it means that this other expert believes that the stock will go up. The fact that equally good experts have different beliefs should dissuade the first expert from selling -- and thus, trades should be very rare. However, in reality, trades are ubiquitous. In this paper, we show that a detailed application …

How Quantum Computing Can Help With (Continuous) Optimization, Christian Ayub, Martine Ceberio, Vladik Kreinovich

Departmental Technical Reports (CS)

It is known that the use of quantum computing can reduced the time needed for a search in an unsorted array: from the original non-quantum time T to a much smaller quantum computation time T_q proportional to the square root √(T) of T. In this paper, we show that for a continuous optimization problem, with quantum computing, we can reach almost the same speed-up: namely, we can reduce the non-quantum time T to a much shorter quantum computation time √(T) * ln(T).

A Theoretical Explanation For The Efficiency Of Generalized Harmonic Wavelets In Engineering And Seismic Spectral Analysis, Michael Beer, Afshin Gholamy, Vladik Kreinovich

Departmental Technical Reports (CS)

Wavelets of different shapes are known to be very efficient in many data processing problems. In many engineering applications, the most efficient shapes are shapes of a generalized harmonic wavelet, i.e., a wavelet of the shape w(t) = t^a * exp(b * t) for complex b. Similar functions are empirically the most successful in the seismic analysis -- namely, in simulating the earthquake-related high-frequency ground motion. In this paper, we provide a theoretical explanation for the empirical success of these models.

Computational Complexity Of Experiment Design In Civil Engineering, Olga Kosheleva, Yan Wang, Vladik Kreinovich

Departmental Technical Reports (CS)

To guarantee reliability and safety of engineering structures, we need to regularly measure their mechanical properties. Such measurements are often expensive and time-consuming. It is therefore necessary to carefully plan the corresponding measurement experiments, to minimize the corresponding expenses.

It is known that, in general, experiment design is NP-hard. However, the previous proofs dealt either with nonlinear systems, or with situations with low measurement accuracy. In civil engineering, however, most systems are well-described by linear systems, and measurements are reasonably accurate. In this paper, we show that experiment design is NP-hard even for civil engineering problems. We show that even …

Perfect Reproducibility Is Not Always Algorithmically Possible: A Pedagogical Observation, Jake Lasley, Salamah Salamah, Vladik Kreinovich

Departmental Technical Reports (CS)

Uses of computer-based based systems often want perfect reproducibility: when encountering the same situation twice, the system should exhibit the same behavior. For real-life systems that include sensors, this is not always possible: due to inevitable measurement uncertainty, for the same actual value of the corresponding quantity, we may get somewhat different measurement results, and thus, show somewhat different behavior. In this paper, we show that the above-described ideal reproducibility is not possible even in the idealized situation, when we assume that a sensor can perform its measurement with any given accuracy.

How To Define "And"- And "Or"-Operations For Intuitionistic And Picture Fuzzy Sets, Christian Servin, Reynaldo Martinez, Peter Hanson, Leonel Lopez, Vladik Kreinovich

Departmental Technical Reports (CS)

The traditional fuzzy logic does not distinguish between the cases when we know nothing about a statement S and the cases when we have equally convincing arguments for S and for its negation ~S: in both cases, we assign the degree 0.5 to such a statement S. This distinction is provided by intuitionistic fuzzy logic, when to describe our degree of confidence in a statement S, we use two numbers a₊ and a₋ that characterize our degree of confidence in S and in ~S. An even more detailed distinction is provided …

Why High-Level Attention Constantly Oscillates: System-Based Explanation, Griselda Acosta, Eric Smith, Vladik Kreinovich

Departmental Technical Reports (CS)

In many situations like driving, it is important that a person concentrates all his/her attention at a certain critical task -- e.g., watching the road for possible problems. Because of this need to maintain high level of attention, it was assumed, until recently, that in such situations, the person maintains a constantly high level of attention (of course, until he or she gets tired). Interestingly, recent experiments showed that in reality, from the very beginning, attention level oscillates. In this paper, we show that such an oscillation is indeed helpful -- and thus, it is necessary to emulate such an …

Assessment Of Cardiac Indices Using M-Mode Echocardiography In Horse With Tachycardia, Mohamed Youssef, Medhat Nassif, Sabry El-Khodery, Maged El-Ashker, Alshimaa Farag

Mansoura Veterinary Medical Journal

The aim of this study was to assess the effect of tachycardia associated with abdominal pain in horse with colic on echocardiographic measurements. For this purpose, 20 horses were selected for this study; from which 10 healthy horses were randomly selected (control group), and 10 diseased horses exhibiting the clinical signs of flatulent colic referred to the hospital of Faculty of Veterinary Medicine, Mansoura University, Egypt. Cardiac functions were evaluated using M- mode echocardiography for measurement of the cardiac indices and functions. In horses with flatulent colic, there was a significant (P < 0.05) decrease in interventricular septal thickness at end- systole (IVSTs), left ventricular internal diameter at end- diastole (LVIDd), left ventricular posterior wall at end-diastole (LVPWd), stroke volume (SV), and ejection fraction (EF) compared with control group. However, there was a significant (P < 0.05) increase in left ventricular volume at end- systole (ESV) in comparison with control group. The results of the present study indicate that evaluation of cardiac indices and functions via echocardiography may be of great benefit for evaluation of clinical outcome of tachycardia associated with abdominal pain in horses.

Pharmacological Studies On Marbofloxacin On Diarrheic Calves, Mohamed El-Sayed, Rasha El- Taysh, Ayat Abd El-Rahman

Mansoura Veterinary Medical Journal

One –hundred diarrheic calves were used to differentiate various reasons for calf diarrhea by using rapid diagnostic kits which found the main causative agents for diarrhea occurrence are corona virus (28%), Rota virus (25%), Cryptosporidium (24%) and E. coli (23%), Respectively, in addition to study concurrent use of marbofloxacin (a third generation member of quinolone) in treatment of diarrheic calves infected with E. coli. Then twenty Holstein calves (0-10 days old) in special dairy farm at Damietta Governorate were isolated and divided into two groups, each group contain ten animals. First group was kept as control without any drug. The …

Implementation Of The Bin Hierarchy Method For Restoring A Smooth Function From A Sampled Histogram, Olga Goulko, Alexander Gaenko, Emanuel Gull, Nikolay Prokof'ev, Boris Svistunov

Physics Faculty Publications and Presentations

We present BHM, a tool for restoring a smooth function from a sampled histogram using the bin hierarchy method. The theoretical background of the method is presented in [1]. The code automatically generates a smooth polynomial spline with the minimal acceptable number of knots from the input data. It works universally for any sufficiently regular shaped distribution and any level of data quality, requiring almost no external parameter specification. It is particularly useful for large-scale numerical data analysis. This paper explains the details of the implementation and the use of the program.

Swift, Nustar And Xmm-Newton Observations Of The Nls1 Galaxy Rxj2317.8–4422 In An Extreme X-Ray Low Flux State, Dirk Grupe

Faculty Research at Morehead State University

We report the discovery of RX J2317.8–4422 in an extremely low X-ray flux state by the Neil Gehrels Swift observatory in 2014 April/May. In total, the low-energy X-ray emission dropped by a factor 100. We have carried out multi-wavelength follow- up observations of this Narrow-Line Seyfert 1 galaxy. Here we present observations with Swift, XMM-Newton, and NuSTAR in October and November 2014 and further monitoring observations by Swift from 2015 to 2018. Compared with the beginning of the Swift observations in 2005, in the November 2014 XMM-Newton and NuSTAR observation RX J2317–4422.8 dropped by a factor of about 80 in …
