Also, by employing software defined networking and link adaptation-based load balancing, the framework ensures optimal resource allocation and efficient resource utilization. Addressing these issues, this paper proposes a five-layered heterogeneous mist, fog, and cloud-based IoHT framework capable of efficiently handling and routing (near-)real-time as well as offline/batch mode data. However, due to the critical and heterogeneous nature of healthcare data, maintaining high quality of service (QoS)-in terms of faster responsiveness and data-specific complex analytics-has always been the main challenge in designing such systems. With the aim of reducing healthcare costs and providing improved and reliable services, several healthcare frameworks based on Internet of Healthcare Things (IoHT) have been developed. This technological integration opened up new possibilities in many disciplines including healthcare and well-being.

The study is relevant to the synthesis of bio-magnetic nanofluids of potential interest in wound treatments, skin repair and smart coatings for biological devices.read more read lessĪbstract: Rapid developments in the fields of information and communication technology and microelectronics allowed seamless interconnection among various devices letting them to communicate with each other. Velocity, temperature as well as concentration rises with convective heating parameter. Magnetic field causes to reduce velocity and enhances temperature and concentration. It is found that velocity increases whilst temperature and concentration reduce with the velocity slip. The effects of the emerging thermophysical parameters namely, stretching/shrinking, velocity slip, magnetic field, convective heat transfer and buoyancy ratio parameters, on the dimensionless velocity, temperature and concentration (nanoparticle fraction) are depicted graphically and interpreted at length. Validation of the Maple solutions is achieved with previous non-magnetic published results. The transformed equations are solved numerically using the Runge–Kutta–Fehlberg fourth fifth order method from Maple. The transport equations along with the boundary conditions are first converted into dimensionless form and following the implementation of a linear group of transformations, the similarity governing equations are developed. A convective heating boundary condition is incorporated.

It's easy to get around this once you know it's happening.Abstract: Steady two-dimensional magnetohydrodynamic laminar free convective boundary layer slip flow of an electrically conducting Newtonian nanofluid from a translating stretching/shrinking sheet in a quiescent fluid is studied. Why should that imply that our search space is complex? These issues are independent. If a function returns complex values and we would like to find a point where it's zero, we would effectively be setting two constraints on the input variables using just one equation. The other idea, to use a change of variables, could also work. Also, it uses the same input format and algorithms, with the only conspicuous difference being that it doesn't include the "trust region dogleg" method, that fsolve(.) does. Now, there is no way documented on fsolve's help page of bounding the domain, but checking this answer, it turns out that there is a function lsqnonlin(.), which is very similar to fsolve(.), except that it does allow us to specify lower and upper bounds on the variables.
Or adjust the function to not return complex numbers.
In the example from the question this probably happens because fsolve(.) calls the anonymous function with x(2) being negative at some point, which the function then raises to the power of 0.1, producing a complex output.Īnyway, the two suggestions in the above post are to I don't see this as logical behaviour, but that's the way it works. This post by MathWorks Support says that if the objective function ever returns a complex number, then fsolve(.) automatically switches to treat the input variable as being complex as well.
