Background: Microscopic description of spontaneous fission is one the most challenging subjects in nuclear physics. It necessary to evaluate collective potential and inertia along a path for quantum tunneling or low-energy fission. In past studies dynamics based on energy density functional (EDF) theory, has been evaluated with cranking approximation, which neglects dynamical residual effects. ...

We report on our experience in implementing and evaluating nine, state-of-the-art single and multicore real-time dynamic voltage and frequency scaling (DVFS) schedulers on an embedded Linux platform. The algorithms include CC-EDF, LA-EDF, DRA, AGR, CVFS, and DR, among others, and the platform is a dual-core ARM Cortex-A9 MPCore processor/PandaBoard, running a real-time Linux kernel. Our evaluat...

We calculate properties of the ground and excited states of nuclei in the nobelium region for proton and neutron numbers of 92 ≤ Z ≤ 104 and 144 ≤ N ≤ 156, respectively. We use three different energy-densityfunctional (EDF) approaches, based on covariant, Skyrme, and Gogny functionals, each with two different parameter sets. A comparative analysis of the results obtained for quasiparticle spect...

A stable and wavelength-tunable S-band erbium-doped fiber (EDF) ring laser with single-longitudinal-mode oscillation over the operating range of 1480.6 to 1522.9 nm is proposed and experimentally demonstrated. The proposed ring laser provides a fine mode restriction and guarantees the single-frequency operation based on a shorter length EDF serving as auto-tracking filter. Therefore, the perfor...

In this paper we present algorithms for flow admission control at an EDF link scheduler when the flows are characterized by peak rate, average rate and burst size. We show that the algorithms have very low computational complexity and are easily applicable in practice. The complexity can be further decreased by introducing the notion of flex classes. We evaluate the penalty in efficiency that t...

We present a real-time, Linux-based testbed called LITMUS, which we have developed for empirically evaluating multiprocessor real-time scheduling algorithms. We also present the results from such an evaluation, in which partitioned earliest-deadline-first (EDF) scheduling, preemptive and nonpreemptive global EDF scheduling, and two variants of the global PD Pfair algorithm were considered. The ...

There are sporadic task systems schedulable by EDF, which no fixed-priority (FP) algorithm can schedule successfully. For instance, it is known that while all implicit-deadline sporadic task systems with utilization at most one are EDF-schedulable on a unit-capacity uniprocessor, there are implicit-deadline sporadic task systems that are not schedulable by any FP algorithm, and have utilization...

In a previous research project [5], we found there are several disadvantages of the current Linux scheduler. So we employed a alternative scheduler, Resource-Based Earliest Deadline First scheduler(RB-EDF), to solve these problems. Though RB-EDF performs better than the Linux scheduler in handling soft realtime processes, it can not enforce resource usages smaller than 1 tick(10ms) using the re...
