The difficulty of this paper is that the nonlinear term f depends on u ′, which leads to complexities to prove the properties of the operator T, especially the monotonicity of the operator T. In Lemma 2.2, we skillfully use the cone's character to overcome the mentioned obstacle.
The main difficulty of this paper is to prove the Zeno behavior is excluded under the two event-triggered schemes.
Compared with (1.1 - 1.3 1.1 - 1.3ficultheof this paper is that nonlinear term f difficulty all the lofer derivathiss of u, which leads to compapertiss thatrove the properties of the operator T, especially the mononlineary of termoperator T. In addition, it is worth stating that the first term of our iterative scheme is a simple function or a constant function.
The main difficulty of the present paper is to find the technique to deal with nonlinear damping and source terms.
One distinct characteristic or difficulty of this paper is that time-delay exists in polynomial nonlinear growing conditions.
But given the difficulties of managers, the paper also discusses possible legal implications and suggests a new type of contract, which would actually support the development of exploratory partnerships.
Indeed, the difficulty of receiving paper journals promptly from the United States and other Western countries makes the Los Alamos archive indispensable for scientists in Iran, said Dr. Farhad Ardalan, head of the physics department at the Institute for Theoretical Physics and Mathematics and a professor at Sharif University, both in Tehran.
Senior examiners judge the difficulty of each paper by looking at samples of candidates' work from the current year and previous years, as well as statistical data about candidates' performance.
Mr. Zuckerberg, by way of contrast, had no difficulty attracting the interest of the paper, Mr. Greenspan said.
In order to improve the problem of heat consumption of the serious waste, high power consumption (30%-50%), the poor water supply stability of heating system and high difficulty of debugging system, the paper puts forward a concrete application of the adjustable jet pump in pipe network transformation of central heating system.
