AIMS Assess patients' preferences in a pilot crossover study of two different electronic voiding diaries against a standard paper diary. Assess urological health professional (HP) opinions on the electronic bladder diary reporting system. METHODS Two different electronic diaries were developed: (1) electronically read diary-a card with predefined slots(More)
This paper proposes a new algorithm to solve cellular layout design problem (CLDP) taking terrain variation and traffic demand into consideration. Based on the nature of the terrain, user distribution, user demand, and growth rate, the distribution of the cells is specified. The proposed algorithm has been simulated for the area with flat terrain and(More)
In this paper, a generalized model is proposed to analyze the impact of propagation environment and velocity on the handover performance of user equipment (UE) for long term evolution (LTE) systems. An adaptive time window is defined within the generalized model, to provide additional flexibility to perform handover procedure over conventional reference(More)
In this paper, an improved target detection algorithm for MIMO airborne radar has been proposed namely, Compressive Parametric Generalized Likelihood Ratio Test (CP-GLRT). The Parametric Generalized Likelihood Ratio Test (P-GLRT) and Generalized likelihood ratio test (GLRT) are also studied considering the availability of secondary data. The signal is(More)
Lifetime maximisation is a key challenge in the design of resource constrained wireless sensor networks (WSNs). This leads the research communities to investigate energy conservation techniques for WSNs while maintaining the required quality of service. Dynamic clustering is considered as one of the most well established energy conservation techniques in(More)
In this paper, a geometrically based 3-D propagation model is presented for macrocellular land mobile radio channel with a mobile station (MS) located at the center of a 3-D scattering semi-spheroid and a base station (BS) employing a directional antenna located outside of the semi-spheroid. The effect of directional antenna is thoroughly observed on the(More)
A three dimensional (3-D) geometric channel model is proposed for air-to-ground (A2G) communication environments. The proposed model considers air station (AS) and ground base station (BS) located at foci points of a virtual bounding ellipsoid corresponded from the delay of longest propagation path. The scattering region around the ground BS is thus(More)
Herein, we study the feasibility of enhanced information throughput capability of Multiple Input Multiple Output Orthogonal Frequency Division Multiplexing (MIMO-OFDM) based wireless communication systems in the context of increasing wireless capacity demand. The concept of Fractional Sampling (FS) is exploited for this purpose to take advantage of(More)
Energy constrain within wireless sensor network (WSN) while transmitting wireless signal in response to a detected event has been addressed. Significant amount of power is consumed during wireless transmission data from the sensor node compared to the other relevant processing within the node. It is conventional to transmit training symbols to bias the(More)
