Abstract: Computer simulations are powerful tools for virtual experiments as compared to real time evacuation drills that are difficult to implement as they are costly and some times dangerous. Simulation is an important tool for emergency response and is used for assessing the vulnerability of a space as well as for training, planning, and decision making. This paper presents AvatarSim, which is a multi-agent system, for simulating emergency evacuation scenarios. It models human behavioral parameters such as stress, anger, and panic which brings a sense of reality during emergency evacuations. It is created in Java and can be displayed on a web browser. The graphical user interface provides agent oriented support for modeling and simulating the behavior of agents in a multi-agent environment.

Abstract: In this paper the speech emotion verification using two most popular methods in speech processing and analysis based on the Mel-Frequency Cepstral Coefficient (MFCC) and the Gaussian Mixture Model (GMM) were proposed and analyzed. In both cases, features for the speech emotion were extracted using the Short Time Fourier Transform (STFT) and Short Time Histogram (STH) for MFCC and GMM respectively. The performance of the speech emotion verification is measured based on three neural network (NN) and fuzzy neural network (FNN) architectures; namely: Multi Layer Perceptron (MLP), Adaptive Neuro Fuzzy Inference System (ANFIS) and Generic Self-organizing Fuzzy Neural Network (GenSoFNN). Results obtained from the experiments using real audio clips from movies and television sitcoms show the potential of using the proposed features extraction methods for real time application due to its reasonable accuracy and fast training time. This may lead us to the practical usage if the emotion verifier can be embedded in real time applications especially for personal digital assistance (PDA) or smart-phones.

Abstract: This paper surveys the role ontologies might play in the whole software development life cycle. Use of ontologies in each phase of software development yields competitive advantage over traditional approach enabling greater information sharing and reuse. In this survey paper, we present a concise description of various ontology-based approaches in Software Engineering ordered by their position in the Software Engineering life cycle. We also report ontology editor tool Protege as part of our survey.
