Including concepts of entrepreneurship in an engineering education is nothing new. It would be difficult to find a university that does not offer several courses or specific programs in entrepreneurship. However, find...

Some real problems are more naturally modeled by hybrid Bayesian networks that consist of mixtures of continuous and discrete variables with their interactions described by equations and continuous probability distributions. However, inference in such general hybrid models is hard. Therefore, existing approaches either only deal with special instances, such as Conditional Linear Gaussians (CLGs), or approximate a general model with a restricted version and then perform inference on the simpler model. However, results thus obtained highly depend on the quality of the approximations. This paper describes an importance sampling-based algorithm that directly deals with hybrid Bayesian networks constructed in the most general settings and guarantees to converge to the correct answers given enough time.
Knowledge elicitation is difficult for expert systems that are based on probability theory. The elicitation of probabilities for a probabilistic model requires a lot of time and interaction between the knowledge engin...

In order to assist driver's vision, a real-time recognition system for traffic signs is proposed. After detecting sign candidates, biologically inspired opponent-color filters are used to extract symbol parts of signs. After normalizing the size of symbol, structural features are calculated to identify the sign. 5572 segmented images are used to design the algorithm. In a real-time system, the same sign in a sequence of frames is tracked, and a majority vote is used to integrate the recognition results. For test data, 93.8% recall rate and 99.3% precision rate could be attained. In-vehicle experiment also showed high recall and precision rates.

This paper employs a simulation model of a Supply Chain Management (SCM) system. The main objective of this model is to compare two systems, one using Radio Frequency Identification (RFID), versus the existing system of barcodes. A quantitative analysis based on a simulation model is developed and a comparison between the two systems is discussed. The model runs for both systems using ARENA simulation software. The model is tested using real data. Two scenarios have been developed using the simulation model in order to analyze: 1 Total inventory cost of all chains in the SCM both with and without RFID. 2 Customer satisfaction and customers lost for all chains in the SCM with and without RFID. The cost of RFID installation is going down over time. By combining the lower cost of RFID installation with fast scanning, the use of RFID technology in SCM promises to reduce annual total inventory cost and the number of lost customers. As a result, this research has shown that RFID technology could be used to improve the effectiveness and performance of the entire supply chain system.
