Back Propagation Neural Network Approach for Channel Estimation in OFDM System
(Ieee, 2010)In high data rate communication systems which use orthogonal frequency division multiplexing as a modulation scheme, at receiver channel impulse responses must be estimated for coherent demodulation. In this paper, ... -
Backpropagation Neural Network Applications for a Welding Process Control Problem
(Springer-Verlag Berlin, 2012)The aim of this study is to develop predictive Artificial Neural Network (ANN) models for welding process control of a strategic product (155 mm. artillery ammunition) in armed forces' inventories. The critical process ... -
Bacterial adhesion to braided surgical sutures: an in vitro study
(Springer, 2016)Background Surgical suture materials are accepted to be associated with a substantial proportion of surgical site infections. These infections are related with biofilm formation similar to that of other synthetic and ... -
BAG-1 expression in hyperplastic and neoplastic prostate tissue: Is there any relationship with BCL-related proteins and androgen receptor status?
(Sage Publications Ltd, 2005)Aims and background: To evaluate the function and distribution of BAG-1 protein in hyperplastic and neoplastic prostate tissue and establish the relationship between this protein and BCL-related proteins (BCL-2 and BAX), ... -
BALANCING STOCHASTIC ASSEMBLY LINES USING CONSTRAINT PROGRAMMING AND QUEUEING NETWORKS
(Gazi Univ, Fac Engineering Architecture, 2013)As an important component of flow type production systems, assembly lines are widely used from automotive, appliance to apparel industry. In this research, the aim is finding the optimum task assignment that minimizes the ... -
Balancing stochastic type-II assembly lines: chance-constrained mixed integer and constraint programming models
(TAYLOR & FRANCIS LTD, 2020)In the literature, line balancing is mostly investigated in deterministic environments. But production systems inevitably contain stochastic situations. In this study, the stochastic type-II assembly line balancing problem ... -
Banded karyotypes of the Persian squirrel Sciurus anomalus from Turkey
(Firenze Univ Press, 2008)Karyotypes of seven males and three females of the Persian squirrel, Sciurus anomalus, were analyzed with G- and C-banding techniques and Ag-NOR (nucleolus organizer region) staining. All specimens had the diploid number ... -
Base study for the establishment of national Salmonella control program in hatching farms and table eggs in Turkey
(Scientific Technical Research Council Turkey-Tubitak, 2020)Foodborne infections due to Salmonella are still a major concern worldwide. Particularly contaminated egg and egg related products are the primary sources for human salmonellosis. It is necessary to determine the risk ... -
BCL-2-related apoptosis markers in cutaneous human papillomavirus-associated lesions
(Lippincott Williams & Wilkins, 2004)Background: Human papilloma virus (HPV) is an etiological agent in benign and malignant epithelial tumors. Resistance to apoptotic stimuli by viral strategies represents an immunologic escape mechanism during virus-induced ... -
Bcl-2-related proteins, (alpha)-smooth muscle actin and amyloid deposits in aggressive and non-aggressive basal cell carcinomas
(Taylor & Francis As, 2002)Aberrant expression of bcl-gene products has been implicated in the development of non-melanoma skin cancers. Recently, altered expression of alpha-smooth muscle actin has been proposed as predictive of tumour behaviour ... -
BCL2 expression and its correlation with neuroendocrine differentiation in colon carcinomas
(Pensiero Scientifico Editor, 2004)Aims and background: In this study we investigated the association between BCL2 expression and neuroendocrine differentiation in tubular adenomas and colon carcinomas. We also evaluated the prognostic significance of BCL2 ... -
Beam space processing for low-cost scanners
(I E E E, 1996)A subaperture processing technique suitable for low-cost ultrasound imaging systems is presented. The technique is based on multi-element synthetic aperture approach and beam interpolation. A large receive aperture is ... -
Behavior and strength of hidden Rc beams embedded in slabs
(ELSEVIER, 2020)Reinforced concrete (RC) beams protrude from the ceiling, unless there is an infill wall beneath. Sometimes the construction of these beams is avoided due to aesthetic concerns, and instead a reinforcement arrangement with ... -
Behavior of Postfabricated RC Beams under Monotonic Transverse Loading
(Asce-Amer Soc Civil Engineers, 2019)Postfabricated beams, that is, newly constructed beams in an existing structural system, provide an effective remedial solution to the serviceability and strength problems in an existing floor system and the discontinuities ... -
The behaviour of a typical single-crystal Si solar cell under high intensity of electric field
(Elsevier Science Bv, 2006)The effect of high intensity of electric fields on the operation of a single-crystal Si solar cell was investigated in this work. A single-crystal Si solar cell was irradiated by spontaneous and stimulated light sources. ... -
Behaviour of brick infill walls strengthened with expanded steel plates
(Springer, 2016)The present study was dedicated to investigate an effective, economical and convenient method for strengthening brick infill walls, i.e. the use of externally-bonded expanded steel plates. A total of 30 plastered wall ... -
Behaviour Of Reinforced Concrete Weak Column-Beam Connections
(Gazi Univ, Fac Engineering Architecture, 2014)In this study the behavior of RC weak column-beam connections which have no joint stirrups and lack of column stirrups, are investigated experimentally under earthquake loads. Edge beam to column joints were tested under ... -
Behcet's syndrome and relationship with the ratio of insulin-like growth factor-1 (IGF-1)/IGF-binding protein-3 (IGFBP-3)
(Termedia Publishing House Ltd, 2019)Introduction: Behcet's syndrome (BS) is a chronic inflammatory disease with unknown aetiology. Insulin-like growth factor-1 (IGF-1) and IGF-binding protein-3 (IGFBP-3) have important metabolic properties such as anabolic, ... -
Beneficial effects of melatonin on reperfusion injury in rat sciatic nerve
(Blackwell Munksgaard, 2004)Studies have shown that ischemia-reperfusion (I/R) produces free radicals leading to lipid peroxidation and to damage of the nervous tissue. Melatonin, a main secretory product of the pineal gland, has free radical scavenging ... -
Bernstein durrmeyer operators based on two parameters
(Univ Nis, 2016)In the present paper, we study the applications of the extension of quantum calculus based on two parameters. We define beta function and establish an identity with gamma function, for two parameters (p, q), ie. the ...
