In scaled technologies, large cell-to-cell interference and FN tunneling disturbance degrade threshold voltage (Vt) window which we can place program states. Moreover, in Triple Layer Cell (TLC) NAND Flash we should place seven program states (P1 ~ P7) in the narrow Vt window, incurring large biterror rate (BER). In this paper, we propose a state re-ordering technique to increase the efficienc...

todays, in many modern applications, we search for frequent and repeating patterns in the analyzed data sets. in this search, we look for patterns that frequently appear in data set and mark them as frequent patterns to enable users to make decisions based on these discoveries. most algorithms presented in the context of data stream mining and frequent pattern detection, work either on uncertai...

In this paper, a novel dynamic contention window control scheme is presented to improve the performance and energy efficiency of IEEE 802.11-based CSMA/CA DCF wireless networks operating in ad-hoc mode. The number of competing nodes in physical carrier sense systems has a major influence on the probability of collisions and a subsequent impact on DCF performance and on the energy consumed. A ne...

We report inverted small molecular organic solar cells using a doped window layer as an optical spacer. The optical spacer was used to shift the optical field distribution inside the active layers, generating more charge carriers from sunlight. In this report, N,N,N',N'-tetrakis(4-methoxyphenyl)-benzidine (MeO-TPD) was doped with 2,2-(perfluoronaphthalene-2,6-diylidene)dimalononitrile (F6-TCNNQ...

This paper presents a novel TaN-Al₂O₃-HfSiOx-SiO₂-silicon (TAHOS) nonvolatile memory (NVM) design with dipole engineering at the HfSiOx/SiO₂ interface. The threshold voltage shift achieved by using dipole engineering could enable work function adjustment for NVM devices. The dipole layer at the tunnel oxide-charge storage layer interface increases the programming speed and provides satisfactory...

Recently designed cross-layer contention based synchronous MAC protocols like the PRMAC protocol, for wireless sensor networks (WSNs) enable a node to schedule multi-hop transmission of multiple data packets in a cycle. However, these systems accommodate both the request-to-send data process and the confirmation-to-send data process in the same data transmission scheduling window (i.e. data win...
