Building Leadership Effectiveness This program encourages leaders to develop practices that transform values into action, vision into realities, obstacles into innovations, and risks into rewards. Participants will be introduced to the five practices of exemplary leadership: modeling the way, inspiring a shared vision, challenging the process, enabling others to act, and encouraging the heart Coaching & Communicating for Performance Coaching & Communicating for Performance is a highly interactive program that will give supervisors and managers the opportunity to build skills that will enable them to share expectations and set objectives for employees, provide constructive feedback, more effectively engage in learning conversations, and coaching opportunities. Skillful Conflict Management for Leaders As a leader, it is important to understand conflict and be effective at conflict management because the way conflict is resolved becomes an integral component of our university’s culture. This series of conflict management sessions help leaders learn and put into practice effective strategies for managing conflict.

Graphical user interface (GUI) systems were considered as obstructions for the visually impaired users since it relied too much on visual channel. Thus, various auditory stimuli combined with speech served as complementary communicating methods in these systems. The purpose of this study was to compare the performance of musical stimuli (called earcons) with different constructions for transmitting positional information of auditory cursors to visually impaired users. Four different types of earcons including sequence of notes (SE), regrouped sequence of notes (R-SE), quadrant (QU), and decimal digit (DE) were studied. Twenty subjects participated in navigation of abstract coordinate locations within a graphical interface divided into 40 rows and 40 columns. At most six timbres and voices were used in construction of earcons to avoid ambiguity and confusion. Both objective and subjective criteria were adopted in the evaluation of the four types of earcons. The results of ANOVA indicated that: 1) compared with SE and QU, R-SE and DE have lower error rates; 2) with SE method, more errors occurred in the area far from origin than the area near origin, whereas error distribution was better-proportioned in R-SE, QU and DE; 3) efficiency was much higher in QU and DE than SE and R-SE. Finally discussed in this paper are advantages and disadvantages of the four methods for navigation in GUI system for visually impaired users.

Locomotion mode recognition is one of the most important aspects for the control of motion rehabilitation systems, e.g. lower-limb prostheses and exoskeletons. In this paper, we propose a capacitance based sensing system for recognizing human locomotion modes. The proposed system includes two rings as sensing front-ends of body capacitance, two sensing circuits for processing the signals and the gait event detection system. The deformation of muscles can be reflected by the changes of capacitance signals. To validate the developed prototype, nine locomotion modes are monitored and ten channels of capacitance signals are collected for locomotion mode recognition. With the combination of capacitive sensing approach and phase-dependent classification method, satisfactory recognition results are obtained.

The problem of absolute stability with a guaranteed domain of attraction is studied for a class of MIMO discrete-time Lur'e systems with local sector nonlinearities by means of piecewise-linear Lyapunov functions along with mixed monotone decomposition of the systems. A sufficient condition is presented which ensures that the domain of attraction coincides with the domain of the sector constraints, so as to achieve the largest absolute stability domain. Particular cases where necessary and sufficient results are available are also examined. Moreover, the existence of positively invariant rectangular sets for the system under consideration is related to well-known M-matrix conditions. Such sets may provide invariant estimates of the guaranteed domain of attraction. The robustness issue is further discussed for system parameter uncertainties described by matrix polytopes, and vertex results are obtained. The main result is illustrated with an example.

Absolute stability and guaranteed domain of attraction for MIMO discrete-time Lur'e systems

This paper studies the evolution of social power in influence networks with stubborn individuals. Based on the Friedkin-Johnsen opinion dynamics and the reflected appraisal mechanism, two models are proposed over issue sequences and over a single issue, respectively. These models generalize the original DeGroot-Friedkin (DF) model by including stubbornness. To the best of our knowledge, this paper is the first attempt to investigate the social power evolution of stubborn individuals basing on the reflected appraisal mechanism. Properties of equilibria and convergence are provided. We show that the models have same equilibrium social power and convergence property, where the equilibrium social power depends only upon interpersonal influence and individuals' stubbornness. Roughly speaking, more stubborn individual has more equilibrium social power. Moreover, unlike the DF model without stubbornness, we prove that for the models with stubbornness, autocracy can never be achieved, while democracy can be achieved under any network topology.

This paper studies optimization and coordinated control of multiple biomimetic robotic fish. A platform for designing and optimizing parameters of biomimetic robotic fish is constructed. For optimizing parameters, the platform introduces a pertinent algorithm (cyclic direction method) which proves to be more effective and feasible compared with tabu search algorithm. Furthermore, the multiple robotic fish coordinated control system (MRFCS) is built up in the studies of coordinated control strategies for multiple robotic fish. Considering the difficulties of controlling robotic fish in water environment, a novel behavior-selection mechanism is proposed to harmonize the behaviors of our robotic fish. Experiments on orderly passing-hole, competing with manually controlled fish, and water polo show that our robotic fish exhibit good underwater performance, and the coordinated control strategies proposed are effective
