A Conceptual Framework For E-Branding Strategies In The Non-Profit Sector, Horst Treiblmaier, Irene Pollach, Arne Floh Jan 2004

A Conceptual Framework For E-Branding Strategies In The Non-Profit Sector, Horst Treiblmaier, Irene Pollach, Arne Floh

Journal of International Technology and Information Management

E-branding provides non-profit organizations (NPOs) with new opportunities to communicate their missions, which is of paramount importance in a market segment that competes for donations and voluntary labor. Since successful e-branding is determined by both internal and external communication strategies, we developed a framework which explains the interdependency of these two factors in NPOs. Our findings are based on qualitative interview data and a website analysis of eleven Austrian NPOs. The NPOs' internal and external e-communication strategies are categorized into three successive levels each and combined in a two-dimensional grid, which shows how NPOs integrate their communication strategies.

Decentralized Neural Network Control Of A Class Of Large-Scale Systems With Unknown Interconnection, Wenxin Liu, Jagannathan Sarangapani, Donald C. Wunsch, Mariesa Crow

Electrical and Computer Engineering Faculty Research & Creative Works

A novel decentralized neural network (DNN) controller is proposed for a class of large-scale nonlinear systems with unknown interconnections. The objective is to design a DNN for a class of large-scale systems which do not satisfy the matching condition requirement. The NNs are used to approximate the unknown subsystem dynamics and the interconnections. The DNN is designed using the back stepping methodology with only local signals for feedback. All of the signals in the closed loop (system states and weights estimation errors) are guaranteed to be uniformly ultimately bounded and eventually converge to a compact set.

Adaptive Critic Neural Network-Based Object Grasping Control Using A Three-Finger Gripper, Gustavo Galan, Jagannathan Sarangapani

Electrical and Computer Engineering Faculty Research & Creative Works

Grasping of objects has been a challenging task for robots. The complex grasping task can be defined as object contact control and manipulation subtasks. In this paper, object contact control subtask is defined as the ability to follow a trajectory accurately by the fingers of a gripper. The object manipulation subtask is defined in terms of maintaining a predefined applied force by the fingers on the object. A sophisticated controller is necessary since the process of grasping an object without a priori knowledge of the object's size, texture, softness, gripper, and contact dynamics is rather difficult. Moreover, the object has …
