Collaborative Software Development: Experimental Results

The experimental results of a collaborative problem solving and program development model that takes into consideration the cognitive and social activities that occur during software development is presented in this paper. This collaborative model is based on the dual common model that focuses on individual cognitive aspects of problem solving and programming. The dual common model, shown to improve the problem solving and programming skills of individual programmer as stated in F. P. Deek (1997), was extended to integrate groupware needs. The model was tested using the groupware tool Groove. The study includes four conditions: groove and the collaborative model, Groove alone, the collaborative model alone, and neither groove or the collaborative model. The subjects were students of a graduate course in object oriented programming at the New Jersey Institute of Technology

Design and implementation of a novel superfusion system for ex vivo characterization of neural tissue by dielectric spectroscopy (DS) Design and implementation of a novel superfusion system for ex vivo characterization of neural tissue by dielectric spect

Abstract Dielectric spectroscopy is a widely utilized electrophysiological characterization method. The obtained dielectric spectra and derived properties have the potential of providing significant information regarding changes in the physiological state of a biological system. However, since many of the dielectric properties are obtained in vitro from excised tissue far removed from physiological conditions, the value of the information obtained may be diminished. In this paper, we introduce a superfusion system that is designed to produce ex vivo dielectric spectroscopy measurements by providing the living tissue with a continuous and ample supply of nutrients and oxygen while removing metabolites and other waste. This superfusion system provides the convenience of in vitro measurement while concurrently producing results that can be more closely correlated with actual physiological changes in the biological system
