Background In vivo Cardiac Diffusion Tensor Imaging (cDTI) remains extremely challenging due to a mixture of cardiac and respiratory motion. In previous work a prospective navigator technique (NAV) has been implemented and compared to breath-hold (BH) acquisitions. Statistically significant differences were found between BH and NAV techniques for helix-angle (HA) values. Further interrogation o...

Background In conventional prospective respiratory navigator (NAV) acquisitions, 40-60% of the acquired data are discarded resulting in low efficiency and long scan times [1,2]. Compressed-sensing Motion Compensation (CosMo) has a shorter fixed scan time by acquiring the full inner k-space and estimating the NAV-rejected outer k-space lines [3]. Respiratory motion will mainly manifest itself as...

This paper starts with a theoretical discussion on the relationship between performance and accountability in public organizations with a special focus on administrative reforms. Accountability theory is discussed and related to different aspects of performance. How ambiguous is the relationship between accountability and performance? Do different types of accountability relate to different asp...

Enterprise resource planning (ERP) solution implementation is a complex process that requires substantial resources and efforts and involves considerable risks reflected in the time, scope, and cost of project implementation, yet the results are very uncertain. As ERP hype has reached large organizations as well as small and medium enterprises, we examined the critical success factors in ERP im...

In wireless network RTS/CTS frame exchange protocol is widely used to avoid packet collisions. However, the protocol lacks the ability to release the reserved but unused channel. For Mobile Ad hoc NETworks (MANET), this often keeps the channel unnecessarily inaccessible, resulting in inefficient channel utilization. In this paper, we propose innovative schemes which can optimize the Medium Acce...

In this paper, we obtained the optimized network allocation vector (NAV) for underwater handshaking-based protocols, as inefficient determination of the NAV leads to unnecessarily long silent periods. We propose a scheme which determines the NAV by taking into account all possible propagation delays: propagation delay between a source and a destination; propagation delay between a source and th...
