This paper deals with the Featured Driven Development (FDD), an agile software development method. According to the requirement analysis for the FDD method application, an information system has been created providing all team members with instruments to follow the method. This tool has been implemented as a multi-user web-based application enabling creation of feature lists, planning a project...

In this paper, an Integrated Radio Resource Allocation (IRRA) framework is proposed for enhanced uplink UTRA-FDD with fixed relay stations (FRSs). It comprises two entities: Relaying Link Scheduler (RLS), and Transmission Mode Aware Packet Scheduler (TMAPS). RLS is responsible for the scheduling of user transmission modes (direct or relaying) and routes, whereas TMAPS is responsible for the sch...

Multiple antennas increase significantly the capacity of wireless links under the assumption of perfect channel state information (CSI). In practice, however, in time division duplex (TDD) or frequency division duplex (FDD) systems, the available CSI is obtained with training and/or limited feedback and hence, is not perfect. In this work, we derive tight capacity bounds for the uplink and down...

Estimating downlink (DL) channel state information (CSI) in frequency division duplex (FDD) massive multi-input multi-output (MIMO) systems generally requires pilots and feedback overheads. Accordingly, this paper investigates the feasibility of zero-feedback FDD MIMO based on extrapolation. We use high-resolution parameter estimation (HRPE), specifically space-alternating generalized expectati...

Adaptive antenna arrays have recently been introduced to cope with the high capacity required by the 3 generation (3G) wireless communications systems. As adaptive antenna arrays focus narrow high gain beams towards the desired user and nulls towards interferers, both coverage and capacity of the network can be improved. To establish the performance gain that a smart antenna can deliver in a 3G...

Objectives: Hyperhomocyst(e)inemia is a risk factor for atherosclerotic vascular disease, and it is associated with endothelial dysfunction. Mechanisms responsible for endothelial dysfunction in hyperhomocyst(e)inemia may involve impaired bioavailability of NO, possibly secondary to accumulation of the endogenous NO synthase inhibitor asymmetric dimethylarginine (ADMA) and increased oxidative s...

The motor drive system plays a significant role in the safety of electric vehicles as bridge for power transmission. Meanwhile, to enhance efficiency and stability system, more studies based on AI technology are devoted fault detection diagnosis (FDD) system. This article reviews application techniques FDD recent years. AI-based is divided into two main steps: feature extraction classification....

An Irish Rail intercity train was instrumented for a period of one month with inertial sensors. In this paper, novel calibration algorithm is proposed to determine, reasonable accuracy, vehicle model parameters from the measured response data. Frequency domain decomposition (FDD) used find dominant frequencies in captured Randomly chosen 2 km data segments are number datasets, thereby averaging...
