Millimeter-wave Automotive Radar using Extrapolation for Improved Angular Resolution

Automotive engineers are repeatedly faced with the issue of choosing radars with the best angular resolution while having reduced processing times. In this paper, a novel extrapolation method is presented to estimate the amplitudes and phases for virtual antenna elements at the receiver periphery. This method has shown to resolve two targets...

Wearables white paper

During the last years, we have witnessed the appearance of smart watches, fitness/activity trackers and many other small devices attached to/embedded in our clothes and accessories. These devices are known as wearables. Wearables are Internet of Things (IoT) devices designed for personal use. Coming in various shapes and forms, wearable devices...

Dielectric interface-dependent spatial charge distribution in ambipolar polymer semiconductors embedded in dual-gate field-effect transistors

The spatial charge distribution in diketopyrrolopyrrole-containing ambipolar polymeric semiconductors embedded in dual-gate field-effect transistors (DGFETs) was investigated. The DGFETs have identical active channel layers but two different channel/gate interfaces, with a CYTOP™ organic dielectric layer for the top-gate and an...

Pulse-modulated multilevel data storage in an organic ferroelectric resistive memory diode

We demonstrate multilevel data storage in organic ferroelectric resistive memory diodes consisting of a phase-separated blend of P(VDF-TrFE) and a semiconducting polymer. The dynamic behaviour of the organic ferroelectric memory diode can be described in terms of the inhomogeneous field mechanism (IFM) model where the ferroelectric components...

Rendering high charge density of states in ionic liquid-gated MoS 2 transistors

We investigated high charge density of states (DOS) in the bandgap of MoS2 nanosheets with variable temperature measurements on ionic liquid-gated MoS2 transistors. The thermally activated charge transport indicates that the electrical current in the two-dimensional MoS 2 nanosheets under high charge density state follows the Meyer-Neldel rule....

Discontinuous pn-heterojunction for organic thin film transistors

Utilization of discontinuous pn-oragnic heterojunction is introduced as a versatile method to improve charge transport in organic thin film transistors (OTFTs). The method is demonstrated by depositing n-type dioctyl perylene tetracarboxylic diimide (PTCDI-C8) discontinuously onto base p-type pentacene OTFTs. A more pronounced impact of the...

Shock and bubble collapse loading for close proximity underwater explosions with rigid and deformable targets

The study describes recent simulation results for underwater explosions in close-proximity to rigid and responding targets. Simulations are performed using Chinook, an Eulerian computational fluid dynamics (CFD) code, in standalone mode and coupled with the Lagrangian solver LS-DYNA. Predicted fluid pressures and target deformations are compared...

Changes at the KinA PAS-A dimerization interface influence histidine kinase function

The Bacillus subtilis KinA protein is a histidine protein kinase that controls the commitment of this organism to sporulate in response to nutrient deprivation and several other conditions. Prior studies indicated that the N-terminal Per-ARNT-Sim domain (PAS-A) plays a critical role in the catalytic activity of this enzyme, as demonstrated by...

Evaluating technology transfer in the Clean Development Mechanism and Joint Implementation

To what extent do the Kyoto Protocols flexible mechanisms facilitate technology transfer to reduce greenhouse gas emissions? This analysis reviews the Clean Development Mechanism (CDM) and Joint Implementation (JI) project portfolios, sample sets of projects, and the technology transfer (TT) literature to address this question. Criteria were...
