Measurements are the core of quality systems; the calibration of the measurement devices is a form of evaluating it. The variability of these measurement devices is verified to know the variation inherit in the measurement tool. Additionally the dynamics of the actual production systems cannot be satisfied by the classic approaches of the human visual inspection because they exceed the human capacities and this phenomenon causes the loss of reliability at the outputs of the system. The exposed topics above presents a hybrid model of adaptive Neuro-fuzzy inference system (ANFIS) to evaluate quality features, also this purpose, offers a knowledge based expert system able to do the quality assurance tasks by learning and adaptation. The obtained results provide an acceptable error rate for this class of systems to run at the speed of a manufacturing system. Read More Read Less

Abstract Wireless multimedia sensor networks (WMSN) are a special case of wireless sensor networks, they differ from wireless scalar network primarily in very large memory resources, the nature and volume of the data transmitted, and the energy consumed by each node during the computation and communication. The need to compress images seems unavoidable today. Currently, compression is always performed without loss when it exists... Wireless multimedia sensor networks (WMSN) are a special case of wireless sensor networks, they differ from wireless scalar network primarily in very large memory resources, the nature and volume of the data transmitted, and the energy consumed by each node during the computation and communication. The need to compress images seems unavoidable today. Currently, compression is always performed without loss when it exists because it is so far the only type of compression tolerated by experts. Indeed, lossless compression ensures data integrity and prevents errors. However, this type of compression does not provide significant reduction in the volume of data. In this context, lossy compression may be the most appropriate response. Several compression algorithms have been developed. The objective of this work is to study the major relevant research directions and the latest algorithms for image compression in WMSNs. Read More Read Less

The legal aspects of Internet is explained in the paper through the framework called as Twibel. The evolution of Twibel is traced with Twitter. In this paper the evolution is described with the description of the model. It is possible that the Twibel can create legal liability on the part of the sender if the defamatory material is not protected under the first amendment and the material is either maliciously or intentionally tweeted to the general public.
