Aiming at bridge gap between maximum likelihood decoding (MLD) and belief propagation (BP) decoding for short or medium LDPC codes, we present one modified ordered statistics decoding (OSD) reprocessing method, which is serially concatenated with standard BP. Meanwhile, two novel points in implementation are addressed. For one thing, the new definition of bit reliability proposed enhances error...

Despite the NP hardness of acquiring minimum distance dm for linear codes theoretically, in this paper we propose one experimental method of finding minimum-weight codewords, the weight of which is equal to dm for LDPC codes. One existing syndrome decoding method, called serial belief propagation (BP) with ordered statistic decoding (OSD), is adapted to serve our purpose. We hold the conjecture...

With the advancement of ubiquitous computing, new types of Wireless sensor networks (WSNs) have emerged where sensors perform their tasks even as their surrounding network neighborhood changes, nodes terminate unexpectedly and signal strengths vary dynamically. In such scenarios, it is very important to use efficient service discovery algorithms adapt dynamically network changes. In this paper,...

This paper investigates decoder diversity architectures for short low-density parity-check (LDPC) codes, based on recurrent neural network (RNN) models of the belief-propagation (BP) algorithm. We propose a new approach to achieve in waterfall region, by specializing BP-RNN decoders specific classes errors, with absorbing set support. further combine our an ordered statistics decoding (OSD) pos...

Background: Ocular surface health is closely related to the condition of ocular adnexa, particularly eyelids. Both adnexal disorders and oculoplastic procedures performed treat them can cause (OSD). In this review, we aimed summarize relationship between OSD.
 Methods: narrative an electronic search PubMed/MEDLINE database was conducted using various combinations keywords including “oculop...

OBJECTIVE To evaluate the incidence of ocular surface disease (OSD) and to determine the effects of topical pressure-lowering drugs on ocular surface disease in primary angle closure patients. METHODS This was a cross-sectional comparative study comparing primary angle closure glaucoma (PACG) patients (Group A) with primary angle closure and primary angle closure suspect (Group B). Group A wa...

ABSTRACT To mitigate urbanization impacts on the hydrological cycle, Low Impact Development techniques, especially On-site Stormwater Detention - OSD, are applied worldwide. Besides their frequent use, public knowledge about these techniques and stormwater management is insufficient, particularly in Latin America. Public comprehension LID lead to more acceptance engagement. In this sense, aim o...

PURPOSE The preservative benzalkonium chloride (BAK) may adversely affect ocular surface health. This study evaluated symptoms of ocular surface disease (OSD) in patients previously treated with a BAK-preserved therapy to lower their intraocular pressure, who either continued that therapy or switched to a BAK-free therapy. METHODS Eligible adult patients with ocular hypertension or open-angle...

The goal of operating system (OS) discovery is to learn which OS is running on a remote computer by looking at differences in the TCP/IP stack implementation of different vendors. There are two main strategies for OS discovery: passive, where deductions are made by looking at regular communications between computers, and active, where stimuli are sent to the target to see how it reacts in speci...
