traffic fatalities are a major cause of morbidity and mortality in iran. occupational sleep medicine field needs more cost-effective and applicable tests for screening purposes. this study reports on a pilot screening study for drowsy drivers in an urban iranian sample of commercial drivers. the maintenance of wakefulness test (mwt) measures the ability to remain awake objectively. sleep latenc...

Due to limited functionalities and potentially large number of sensors, conventional routing strategies proposed for distributed control applications (such as mobile ad hoc networks) are not directly applicable in wireless sensor networks. In this paper, we propose a novel meshed multipath routing (M-MPR) with selective forwarding of packets. Our evaluation shows that M-MPR achieves much improv...

An improved method of dynamic route establishment between sensors and sinks is proposed for wireless sensor networks. The method is based on the use of an anycast-based restricted flooding technique and does not require the accumulation and maintenance of state information in network nodes. The proposed scheme is implemented as a simulation model in terms of extended Petri nets. The developed m...

the present study is intended to develop a preventive maintenance (pm) policy for industrial applications, while considering two different objectives: the first objective is to optimize the total maintenance costs, i.e., the preventive maintenance (pm) and emergency maintenance (em) costs per unit time. (cput). the second objective is to design the policy in such a way that the simplicity of it...

improving time series forecastingaccuracy is an important yet often difficult task.both theoretical and empirical findings haveindicated that integration of several models is an effectiveway to improve predictive performance, especiallywhen the models in combination are quite different. in this paper,a model of the hybrid artificial neural networks andfuzzy model is proposed for time series for...

We discuss how telephony software requirements should be structured to reduce maintenance costs. “Feature interaction” problems have become a serious obstacle to add more features to telephone switches. We show why existing public switched telephone networks are hard to modify. We then argue that a more modular, layered requirements architecture can help. Finally we survey approaches for such a...

high processing loads, need for complicated and frequent updating, and high false alarm are some of the challenges in designing anomaly detection and misuse detection systems. we propose a new network-based intrusion detection system (ids) that resolves such shortcomings. our scheme fuses anomaly detection and misuse detection systems, which has not been utilized so far in existing systems. in ...
