The purpose of this paper is to apply the data mining techniques to discover and predict the recovery duration from physical therapy equipment usage patterns based on a classification system and establish selection rules of physical therapy techniques based on the association rule discovery method to support the decision making for physical therapists in the […]
We consider the problem of adaptively routing a fleet of cooperative vehicles within a road network in the presence of uncertain and dynamic congestion conditions. To tackle this problem, we first propose a Gaussian process dynamic congestion model that can effectively characterize both the dynamics and the uncertainty of congestion conditions. Our model is efficient and thus […]
Reducing the queue length and queuing delay in the buffer which in turn reduces congestion and latency in the network are of great importance for real-time video services. This paper proposes a congestion avoidance active queue management, tailored for scalable video coding (SVC). This distortion-constrained (DC) queue management mechanism maximally decreases the queue length and queuing delay […]
The paper presents a frequency reconfigurable microstrip patch antenna printed on a textile substrate. It can be tuned by using active circuitry between Bluetooth and WiMAX operating at 2.4 GHz and 2.5 GHz frequency bands respectively. Indigo blue jeans having relative permittivity 1.68 with thickness 1 mm is used as a textile substrate. The frequency […]
A novel agent based static state estimation strategy for a specific class of physical systems is proposed. Physical systems, (e.g. smart distribution grid) which are well modeled using decentralized measurements and distributed state-space formulations are considered. In such systems, sensor nodes acting as agents estimate only a subset of states, instead of evaluating local estimates […]
Electrical sensors are used to detect and record the electrical activity of the heart over a period of time, this operation is referred to as Electrocardiography (ECG) in medical science. Hence ECG is composed of a set of signal waves that repeats themselves and are usually useful in medical diagnosis, where certain ECG patterns and […]
Wireless Local Area Networks (WLANs) communication means gained widespread reception in recent years and widely used all over world due to its wireless fidelity feature with high data rates assets. With emerged multimedia application on wireless networks and the integration with other cellular networks, requires support for quality of service. In this paper, performance optimization […]
This paper describes how user-specific QoS requirements may improve spectral utilization in heterogeneous networks. Throughput improvements of FTP (File Transfer Protocol) applications benefiting from the rate adaptation and MAC scheduling algorithms for video applications that incorporate user-specific QoS to improve system capacity are demonstrated. These improvements are achieved while user satisfaction for video applications, as […]
IEC 61850, the standard for communication in substations, has resolved the interoperability between intelligent electronic devices (IEDs) from different vendors. Thus, the IEDs’ uniform communication standard contributes to the realization of more sophisticated functionality in substation automation systems. However, there are still several issues unsolved for the simulation, planning, and extension of substation communication network […]
IEEE 802.19.1 is the world first standard that specifies coexistence methods by means of exchanging messages between 802.19.1 coexistence system and wireless systems registered to the coexistence system. We propose a channel allocation mechanism for 802.19.1 management service. The mechanism mainly depends upon channel classification where the CM manages channel availability information based on TV […]
