World Health Organization (WHO) control policy for tuberculosis (TB) includes Bacillus Calmette-Guérin (BCG) vaccine at birth, case detection, and treatment of cases with directly observed therapy short-course (DOTS). This policy has been applied through the Ministry of Health and Population in Egypt...

Aiming at the problems of low stability and limited application conditions in traditional augmented reality, Unity 3D software is applied to realize augmented reality by combining with Vuforia SDK and EasyAR SDK (Software Development Kit). The developed results can be used on mobile terminal and augmented...

Scheduling is one of the most important issues in the operating system, such as the tasks must be affected to the appropriate virtual machines, considering different factors at the same time to ensure better use of resources. A lot of research has been carried out to propose more efficient task scheduling...

For dynamical systems defined by vector fields over a compact invariant set, we introduce a new class of approximated first integrals based on finite time averages and satisfying an explicit first order partial differential equation. These approximated first integrals can be used as finite time indicators...

In this paper, we are concerned with a modified complex short pulse (mCSP) equation of defocusing type. Firstly, we show that the mCSP equation is linked to a complex coupled dispersionless equation of defocusing type via a hodograph transformation, thus, its Lax pair can be deduced. Then the bilinearization...

Serious games which are designed for purposes rather than pure entertainment have become one of the popular topics these days as they have the potential to be effective and efficient teaching tools which are interactive, attractive and immersive. This study conducts a systematic literature review on...

Checkpoint/restart has been an effective mechanism to achieve fault tolerance for many long-running scientific applications. The common approach is to save computation states in memory and secondary storage for execution resumption. However, as the GPU plays a much bigger role in high performance computing,...

We show that the Fisher information matrix of the Birnbaum–Saunders distribution can present numerical problems for some values of the shape parameter. To overcome this problem, we provide a simple analytical approximation which works very well.

In this paper, the maximum likelihood estimates (MLE's) of the parameters of a finite mixture of modified Weibull (MW (alpha, beta, gamma)) distributions are obtained based on type-I and type-II censored samples using the EM algorithm. A simulation study is carried out to study the behavior of the mean...

An invariant of three-dimensional orientable manifolds is built on the base of a slution of pentagon equation expressed in terms of metric characteristics of Euclidean tetrahedra.

The transition from Eulerian to Lagrangian coordinates is a nonlocal transformation. In general, isomorphism should not take place between basic Lie groups of studied equations. Besides, in the case of plane and rotational symmetric motion hydrodynamic equations in Lagrangian coordinates are partially...

A type of Takagi-Sugeno (T-S) Proportional-Integral (PI) fuzzy controllers is studied. The T-S PI fuzzy controller is formed by a T-S Proportional-Derivative (PD) fuzzy controller connected with an integrator. In this particular structure, the T-S PD fuzzy controller is a weighted sum of some linear...

A shape memory alloy (SMA)-based spring actuated gripper (SAG) was designed and developed for facilitating minimally invasive surgeries (MIS). Specifically the research consists of design and development of a SMA spring which acts as the actuator for the gripper. A novel mechanism was also developed...

Background: Augmentation index (AIx) is regarded as a marker of systemic arterial stiffness. Patients with type 2 diabetes mellitus (T2DM) have increased arterial stiffness, but not AIx, which suggests that mechanisms contributing to AIx in T2DM may differ from healthy individuals and be unrelated to...

With the continuous development of the social economy and the deepening of urbanization, large buildings are increasing, and disaster risks associated with large buildings, such as fire risks, are also increasing. Because of large buildings, such as shopping malls, business offices, transportation hubs...

Most sub-Saharan African countries acted early and aggressively in response to the WHO COVID-19 warning by closing schools, international borders, limiting domestic travel and restricting large gatherings. The six most populous sub-Saharan African countries, at the beginning of July 2020 with the exception...

This paper shows Extended Place/transition Net with Attributed Tokens (EPNAT) and a modeling technique using it in order to address the problem of EPN. In software modeling using EPN, objects of which the software consists need to be defined individually as sub-EPN models, even if they have the same...

Introduction: A study was conducted in three districts in Hai Phong province, Vietnam to estimate the population size of the Female Sex Workers (FSW) in June–July 2019. Methods: The procedures included selection of three districts, compilation of a list of accessible venues where FSW congregate, distribution...

In this work, we give a method to construct compatible Poisson structures on Lie groups by means of structure constants of their Lie algebras and some vector field. In this way we calculate some compatible Poisson structures on low-dimensional Lie groups. Then, using a theorem by Magri and Morosi, we...

In terms of the operator Nambu 3-bracket and the Lax pair (L, Bn) of the KP hierarchy, we propose the generalized Lax equation with respect to the Lax triple (L, Bn, Bm). The intriguing results are that we derive the KP equation and another integrable equation in the KP hierarchy from the generalized...

In the construction field, the improvement of the work efficiency is one of important problems. However, the work efficiency using construction equipment depends on their operation skills. Thus, in order to increase the work efficiency, the operation skill is required to be quantitatively evaluated....

A new class of integrable Newton systems in Rn is presented. They are characterized by the existence of two quadratic integrals of motion of so-called cofactor type, and are therefore called cofactor pair systems. This class includes as special cases conservative systems separable in elliptic or parabolic...

A fully braided analog of the Faddeev-Reshetikhin-Takhtajan construction of a quasitriangular bialgebra A(X, R) is proposed. For a given pairing C, the factor-algebra A(X, R; C) is a dual quantum braided group. Corresponding inhomogeneous quantum group is obtained as a result of generalized bosonization....

A novel assessment method of emergency preparedness system vulnerability (EPSV) is established to evaluate the emergency system construction. The assessment index system and its complex network were constructed for EPSV. A simple weighted sum method was used to score the indices. And then the EPSV was...

The manuscript is devoted to nonisentropic solutions of simple wave type of the gas dynamics equations. For an isentropic flow these equations (in one-dimensional and steady two-dimensional cases) are reduced to the equations written in the Riemann invariants. The system written in the Riemann invariants...

Background: The 3 ml volume currently used as the hand hygiene (HH) measure has been explored as the pertinent dose for an indirect indicator of HH compliance. A multicenter study was conducted in order to ascertain the required dose using different products. Method: The average contact duration before...

A single machine scheduling problem with periodic maintenance is studied in this paper. Due to many uncertainties in reality, the processing time is recognized as an uncertain variable. The aim is to minimize the makespan at a confidence level. An uncertain chance-constrained programming model is developed...

With the advent of the Internet of Things (IoT) era, the concept of smart office has gradually come true. To facilitate the management, IoT devices often follow authentication mechanisms as windows domain used, which would cause severe problems once hackers steal those credentials. This study analyzes...
