Vehicular safety applications, such as cooperative collision warning systems, rely on beaconing to provide situational awareness that is needed to predict and therefore to avoid possible collisions. Beaconing is the continual exchange of vehicle motion-state information, such as position, speed, and heading, which enables each vehicle to track its neighboring vehicles in real time. This work pr...

The purpose of the present study was to develop a repetition-load scheme for the eccentric-only bench press exercise. Nine resistance trained men (age: 21.6 ± 1.0 years; 1-repetition maximum [RM] bench press: 137.7 ± 30.4 kg) attended four testing sessions during a four week period. During the first session each subject's 1-RM bench press load utilizing the stretch-shortening cycle was determin...

The concept of witness-hiding suggested by Feige and Shamir is a natural relaxation of zero-knowledge. In this paper we identify languages and distributions for which many known constant-round publiccoin protocols with negligible soundness cannot be shown to be witnesshiding using black-box techniques. One particular consequence of our results is that parallel repetition of either 3-Colorabilit...

High-repetition-rate (80-MHz) femtosecond infrared pulses are generated by difference frequency mixing (DFM) a femtosecond Ti:sapphire laser with a phase-locked synchronized cw mode-locked Nd:YAG picosecond laser. This DFM scheme is of particular interest for generating ultrashort near-IR pulses (~10 fs) because group velocity mismatch with a pump pulse can be ignored. The simplicity and the br...

In this study, segmental and prosodic aspects of word repetition and non-word repetition in typically developing children aged four to six years were investigated. Focus was on developmental differences, and on how tonal word accent and word length affect segment production accuracy. Prosodically controlled words and non-words were repeated by 44 Swedish-speaking children. Repetition accuracy f...

The control and stability of the carrier-envelope phase of few-cycle pulses are crucial issues in attoscience. This project reports on a novel few-cycle mid-infrared source based on optical parametric chirped pulse amplification with 100 kHz repetition rate at a wavelength of 3.2μm and a pulse duration of 67 fs. Due to the design of the source it is supposed to be intrinsically passively carrie...

This paper presents a new polling scheme, that can be used at the Access Point of an IEEE802.11 wireless network as part of the Point Coordination Function, in order to provide guaranteed QoS support of voice traffic. The so called Cyclic Shift polling scheme along with the use of silence detection at the mobile terminals increases the supported number of calls, as a function of the overall rat...

Digital ImageWatermarking is a process of embedding a copy righted information inside the digital image such a way that intruder is not able to trace the information. In this paper a simple visual cryptography based robust digital image watermarking scheme is presented. Watermark Robustness is obtained by using repetition codes and Security of the watermark by visual cryptography. In this metho...

This paper studies energy and spectral efficient Doppler diversity transmissions in the presence of imperfect channel state information (CSI). Fast time-varying fading in high-mobility communication systems introduces Doppler diversity that can benefit system performance. On the other hand, it is more difficult to estimate and track fast time-varying channel; thus, channel estimation errors mig...

The formation of a double-horn current profile is challenging issue in the achievement electron bunch with high peak current, especially for high-repetition-rate X-ray free-electron lasers (XFELs) where more nonlinear and intricate beam dynamics propagation involved. Here, we propose to correct longitudinal phase space distortion photoinjector section dual-mode buncher. In combination evolution...
