  • In this paper, we show that: (1) every strongly ${\omega}$-monolithic space X with countable fan-tightness is Fr$\'{e}$chet-Urysohn; (2) a direct proof of that X is Lindel$\"{o}$f when $C_p$(X) is Fr$\'{e}$chet-Urysohn; and (3) X is Lindel$\"{o}$f when X is paraLindel$\"{o}$f and $C_p$(X) is AP. (3) is a generalization of the result of [8]. And we give two questions related to Fr$\'{e}$chet-Urysohn and AP properties on $C_p$(X).

  • We investigate various properties of ${\kappa}$-net convergence structures and define a ${\kappa}$-net-based continuous function on ${\kappa}$-net $\mathcal{L}^+$-convergence structures, and study relationships between continuity and ${\kappa}$-net-based continuity on ${\kappa}$-net $\mathcal{L}^+$-convergence structures. We also provide some characterizations of ${\kappa}$-net-based continuity.

  • In this paper, moving a fragile object from an initial point to a specific location in the minimum time without damage is studied. In order to achieve this goal, initially, the maximum acceleration and velocity ranges are specified. These ranges can be dynamically generate on the planned path by the manipulator. The path can be altered by considering the geometrical constraints. Later, considering the impulsive force constraint on the object, the range of maximum acceleration and velocity are obtained to preserve object safety while the manipulator is carrying it along the curved path. Finally, a time-optimal trajectory is planned within the maximum allowable range of acceleration and velocity. This time-optimal trajectory planning can be applied to real applications and is suitable for both continuous and discrete paths.

  • Trichotillomania is a neuropsychiatric disorder characterized by repetitive pulling out of one's hair. We present a trichotillomania case study illustrating the effectiveness of habit reversal training, which has recently been found, in western countries, to be a very effective cognitive behavioral treatment. The refractory patient in our study had previously received 1 year of drug treatment and psychiatric consultation for the disorder. We administered 10 habit reversal training sessions, which was followed by an obvious improvement in the patient's trichotillomania symptoms. Our observations indicate that habit reversal training might be effective in the treatment of trichotillomania.

  • Recently, buildings are constructed increasingly higher and even more people are using elevators every day. Therefore, more efficient means of vortical transportation are required. Most of high-rise buildings is equipped with elevators. Unlike one elevator system, a multi-elevator system requires a function, which can distribute multiple elevators effectively. This paper examines a multi-elevator system, which has been modeling mathematically, in order to reduce waiting time and use elevators more effectively.
