ally perceived as arising from extrinsic disorder that breaks the discrete translational invariance of the perfect crystal lattice. Familiar examples include the localized vibrational phonon modes around impurities or defects (such as atomic vacancies or interstitial atoms) in crystals and Anderson localization of electrons in disordered media.1 The usual perception among solid-state researcher...

uterine sarcoma is a rare tumor of mesodermal origin, accounting for 2-6% of uterine malignancies. leiomyosarcoma (lms) has been reported in only 1% of all uterine malignancies and is regarded as the most common primary uterine sarcoma. herein, we present a case of lms with unusual macroscopic features. the patient was a 61-year-old woman with lms, which consisted of a large cystic mass (88×136...

The objective of our paper is to improve efficiency (in terms of throughput or system capacity) for mobile satellite communications. In this context, we propose an enhanced Hybrid Automatic Repeat reQuest (HARQ) for delay tolerant services. Our proposal uses the estimation of the mutual information. We evaluate the performance of the proposed method for a land mobile satellite channel by means ...

This paper presents the architecture of an Intelligent Learning Management System (ILMS) applied to Moodle. Specifically, we present the design and implementation of an agent that select the teaching strategy according to the student's learning style. The chosen teaching strategy is used to filter the learning objects that are displayed to the students.

CEDE both the leg movements and the associated electroen-cephalogram (EEG) changes by as much as 6 seconds. They also reported that the heart-rate changes were greater when occurring with periodic leg movements in sleep (PLMS) than with either isolated (ILMS) or respiratory-related leg movements. We 2 and others 3 have previously reported essentially opposite findings, i.e., that heart-rate cha...

The objective of the proposed work is to develop a Maximum Power Point Tracking (MPPT) controller and inverter by applying adaptive least mean square (LMS) algorithm control total harmonics distortion solar photovoltaic system. advantage LMS given its simplicity reduced required computational time. applied modify Perturb Observe (P&O), MPPT controller. In this controller, used predict power...

We investigate the existence of Intrinsic Localized Modes (ILMs) in nonlinear one-dimensional KleinGordon chains. We use the Lagrangian averaging approach parameterizing ILM by several slow-varying variables, and apply the averaging directly in the action principle. Our preliminary studies yield results for ILM dynamics in accordance with those obtained by other methods.

For a new kind of automatic transmissions using proportional pressure valves to control the clutches directly, a two-degree-of-freedom controller is designed for clutch slip control during the inertia phase of the shift process. The controller is designed based on a low order linear model which is derived from dynamics of the proportional pressure control valve and the vehicle drive line. The f...

Least mean square (LMS) type adaptive algorithms have attracted much attention due to their low computational complexity. In the scenarios of sparse channel estimation, zero-attracting LMS (ZA-LMS), reweighted ZA-LMS (RZA-LMS) and reweighted -norm LMS (RL1-LMS) have been proposed to exploit channel sparsity. However, these proposed algorithms may hard to make tradeoff between convergence speed ...
