Comprehensive analysis of the transient X-ray pulsar MAXI J1409 619
(2020)
We probe the properties of the transient X-ray pulsar MAXI J1409-619 through RXTE and Swift follow-up observations of the outburst in 2010. We are able to phase-connect the pulse arrival times for the 25 d episode during ...
Cyclic and heteroclinic flows near general static spherically symmetric black holes: semi-cyclic flows - addendum and corrigendum
(2017)
We present new accretion solutions of a polytropic perfect fluid onto an f(R)-gravity de Sitter-like black hole. We consider two f(R)-gravity models and obtain finite-period cyclic flows oscillating between the event and ...
Strong gravitational lensing by a charged Kiselev black hole
(2017)
We study the gravitational lensing scenario where the lens is a spherically symmetric charged black hole (BH) surrounded by quintessence matter. The null geodesic equations in the curved background of the black hole are ...
Automatic Detection of Aerial Vehicle in Cloudy Environment by Using Wavelet Enhancement Technique
(2017)
Automatic target detection of surface to air surveillance and tracking systems in video applications is an important issue, because it is the first step for track initiation and continuity. Target detection can be readily ...
Synthesis and characterization of new thiophenebenzimidazole-based electrochromes
(2018)
In the present study, two new donor-acceptor-donor-type molecules were synthesized and the electro-optical properties of the resulting monomers and their corresponding polymers were investigated. Thiophene was selected as ...
Simultaneous determination of copper(II) and zinc(II) via simple acid-base titrimetry using glass pH electrode
(2018)
The combination of potentiometric methods with multivariate calibration techniques allows complex mixtures to be analyzed. In this study, a new method was developed and reported for simultaneous determination of copper(II) ...
A COMPARATIVE STUDY OF THE CAPABILITY OF ALTERNATIVE MIXED INTEGER PROGRAMMING FORMULATIONS
(2018)
In selecting the best mixed integer linear programming (MILP) formulation the important issue is to figure out how to evaluate the performance of each candidate formulation in terms of selected criteria. The main objective ...
Smoothed one-core and core-multi-shell regular black holes
(2018)
We discuss the generic properties of a general, smoothly varying, spherically symmetric mass distribution D(r,theta), with no cosmological term (. is a length scale parameter). Observing these constraints, we show that ...
Integrating features for accelerometer-based activity recognition
(2016)
Activity recognition is the problem of predicting the current action of a person through the motion sensors worn on the body. The problem is usually approached as a supervised classification task where a discriminative ...
New Formulations for the Orienteering Problem
(2016)
Problems associated with determining optimal routes from one or several depots (origin, home city) to a set of nodes (vertices, cities, customers, locations) are known as routing problems. The Traveling Salesman Problem ...
