In cellular networks, the User Equipment (UE) often needs to send control information base station. For example, initiate a connection, UE transmits Zadoff-Chu (ZC) sequence on channel called PRACH, where is randomly selected from up 64 sequences. Also, connected may Scheduling Request (SR) bit PUCCH start an uplink data transmission. this paper, novel access methods, namely, ABF PRACH and SR, ...
introduction: an overlooked but important part of successful root canal treatment is a straight-line access (sla). the purpose of this in vitro study was to compare the efficacy of introfile and prerace rotary instruments with gates glidden (gg) drills in gaining sla by cone-beam computed tomography (cbct). methods and materials: a total of forty five extracted mandibular first molars were sele...
the hypothesis is that recent and frequent exposure to lexical items leads to a more fluent production of speech in terms of rate of speech. to test the hypothesis,a one-way anova experimental design was carried out. 24 sednior students of efl participated in a one-way interview test. data analyses revealed that those who were exposed frequently to the lexical items over a week prior to inter...

Abstract Background and purpose: One of the main factors in establishing health equity is delivering equal spatial access to public medical cares to all members in a society. The aim of this study was to evaluate equity in health by assessing people's access to health care centers using Geographic Information System (GIS) in Kermanshah (west of Iran). Material and methods: In this descript...
all analytical methods are generally based on the measurement of a parameter or parameters which are somehow related to the concentration of the species.an ideal analytical method is one in which the concentration of a species can be measured to a high degree precision and accuracy and with a high sensitivity. unfortunately finding such a method is very difficult or sometimes even impossible.in...
Background and Aim: Open access to scientific information is a new paradigm in scientific communication that facilitates access to research. This study was carried out to identify Tehran University of medical science faculties members’ familiarities with Open access and to survey their attitude about it. Materials and Methods: A descriptive survey method was applied. The study population consis...
the open access (oa) to scholarly articles published in journals, magazines and other literature sources is extremely useful to pharmacy students, teachers, research scholars, scientists and pharmacists to update their knowledge with recent changes in their fields of specialization. open access (oa) to scholarly articles is provided either directly from journal homepages by the publishers or fr...
BACKGROUND Patient access to primary care appointments is not routinely measured despite the increasing interest in this aspect of practice activity. The generation of standardised data (or benchmarks) for access could inform developments within primary care organisations and act as a quality marker for clinical governance. Logically the setting of targets should be based on a sound system of m...
This paper examines two methods of multiple access for optical networks: code-division and wavelength division. Two approaches are given for analyzing code-division systems, and an overview of a proposal for a WDM network will be summarized. Since the maturity of the technologies necessary for such systems diier, the usefulness of a direct comparison between CDMA and WDM is limited; instead, th...
