Abstract Pure tone audiometer is used to determine a person’s hearing threshold level at different frequencies.The hearing test provides an evaluation of the sensitivity of a person’s sense of hearing and is most often performed by an audiologist using an audiometer. There are different types of hearing loss, depending on which part of the hearing pathway is affected. In this study,... Pure tone audiometer is used to determine a person’s hearing threshold level at different frequencies.The hearing test provides an evaluation of the sensitivity of a person’s sense of hearing and is most often performed by an audiologist using an audiometer. There are different types of hearing loss, depending on which part of the hearing pathway is affected. In this study, air and bone path audiograms belong to conductive, sensorineural and mixed hearing losses and their sub groups were obtained. A specialist will always try to localize where in the hearing pathway the problem lays, so as to be able to classify the hearing loss as belonging to one of the groups. This is most important in determining the appropriate treatment. In our study, ANN that was an expert system was improved to classify of these hearing losses. With 98,75% correct classification satisfactory classification results were obtained, which were consistent with diagnostic results by clinical doctors. Read More Read Less

Abstract In mobile environment, the Mobile data synchronization (DS) is a crucial activity and operation because of its extended application in multi-server environment. The current Mobile data synchronization protocols fail to work in multi-server environment. The problem of slow synchronization mode thus need to be eliminated to ensure functioning of the data synchronization. Thus we propose to directly synchoronize the data... In mobile environment, the Mobile data synchronization (DS) is a crucial activity and operation because of its extended application in multi-server environment. The current Mobile data synchronization protocols fail to work in multi-server environment. The problem of slow synchronization mode thus need to be eliminated to ensure functioning of the data synchronization. Thus we propose to directly synchoronize the data between servers by using multi-agent system which is developed on JADE platform. The experimental results obtained by us prove that the DS operations take less than 9 seconds while slow sync operations take more than 99 seconds tosynchronize 300 data records. We document in our study that the inter-server DS system is effective than the current DS system for multi-server environments. Read More Read Less

Abstract Particle swarm Optimization (PSO) is mainly inspired by social behavior patterns of organisms that live and interact within large groups. The term PSO refers to a relatively new family of algorithms that is used to find optimal or near to optimal solutions to numerical and qualitative problems. It is an optimization paradigm that simulates the ability of human to process... Particle swarm Optimization (PSO) is mainly inspired by social behavior patterns of organisms that live and interact within large groups. The term PSO refers to a relatively new family of algorithms that is used to find optimal or near to optimal solutions to numerical and qualitative problems. It is an optimization paradigm that simulates the ability of human to process knowledge. The capability of PSO method to address the maximization and minimization unconstrained problems is investigated through numerous experiments on different test problems. Results obtained are reported. The two variants PSO-IW (Inertia Weight) and PSO-IC (Inertia weight and Constriction factor) are used for the experiments. Conclusions are derived. These variants exhibit different performance for different test problems. Read More Read Less

Abstract In the era of cloud computing, cyberworlds evolve constantly and dynamically where data and data dependencies constantly change. In system development, correspondence to frequent changes in user requirement has become more important. But existing data models are not able to model such dynamically changing information worlds precisely. We consider the Incrementally Modular Abstraction Hierarchy (IMAH) to offer the most appropriate... In the era of cloud computing, cyberworlds evolve constantly and dynamically where data and data dependencies constantly change. In system development, correspondence to frequent changes in user requirement has become more important. But existing data models are not able to model such dynamically changing information worlds precisely. We consider the Incrementally Modular Abstraction Hierarchy (IMAH) to offer the most appropriate mathematical background to model such information worlds and real worlds, as well, by descending from the abstract level to the specific, while preserving invariants. To validate the mechanism, we designed spaces and maps on each level of IMAH by means of Formula Expression, which is a simple finite automaton, and implemented them. We call the data processing system the Cellular Data System (CDS). In this paper, we have applied CDS to the core logic development of a business application that can be adaptable to unexpected situations: a staff assignment information management system. We then verified that use of CDS simplifies business application development. Read More Read Less
