Building information modelling roadmap strategy for Turkish construction sector
No full text#nofulltext# --- Tekin, Hamdi (Arel Author)Building information modelling (BIM) has shown itself as a leading factor in increasing the production and efficiency in the construction sector in many countries. The construction sector in Turkey has made considerable progress in recent years, but the sector lacks effective construction management and information technologies. In order to make further progress and to achieve global goals, the use of BIM is of utmost importance for the construction sector in Turkey. With this perspective, the present study aims to propose a strategic roadmap for BIM adoption to the Turkish construction sector. For this purpose, individual interviews were carried out to reveal the current state of BIM use in Turkey, a strengths, weaknesses, opportunities and threats (SWOT) analysis was conducted and the best practices in BIM adoption worldwide were investigated. The study intends to contribute to the relevant literature by suggesting a roadmap for the preparation of BIM standards as well as underline the importance of education, technological adaptation, public incentives and sanctions. © 2018 ICE Publishing: All rights reserved.BIM technology and its real benefits to the General Services Administration (GSA) were originally developed at Stanford University (Yee et al., 2010). In particular, 3D and four-dimensional (4D) BIM applications were carried out in various public projects in New York, Houston and Los Angeles, providing great benefits both in shortening the project duration and reducing the cost (Yee et al., 2010). In 2003, the GSA Public Building Service (PBS-OCA) published the 3D–4D BIM programme that aims to ensure that the GSA works more efficiently and the design quality and construction requirements are met at the highest level (GSA, 2007; Yee et al., 2010) From 2003 to 2007, 35 pilot projects were executed by BIM, ten of which were completed by 2007 (Zeiss, 2013). When the GSA was as successful as desired in the pilot projects, BIM became an obligation for all projects submitted to the Public Service Commission, which has been utilising the design fund from the 2007 financial year with a decision taken in 2006 (Zeiss, 2013). In addition, the GSA encouraged the use of BIM not only in its own projects but also in other private sector investments. With the imperatives of these obligations and incentives, many projects in the United States have begun to implement BIM. Figure 3 shows the timeline of BIM adoption in the United States. Between 2007 and 2016, many guides were published and the role of BIM was evaluated in many areas such as spatial programme validation, 4D phasing, 3D imaging, energy performance and operations, circulation and security validation (GSA, 2007).Starting in 2001, Senate Properties that manages a major part of the real estate assets owned by the Government has implemented a series of pilot projects to analyse and improve the use of product models that originated from 1960s and 1970s in Finland (SP, 2009; Wong et al., 2009; Zeiss, 2014b). Based on the feedback received, it was decided that sufficient infrastructure was provided at the end of the 6th year and the Senate Properties BIM Requirements was published in 2007 for mandating the use of BIM models meeting the IFC (Industry Foundation Classes) standards in public projects (SP, 2009; Wong et al., 2009). The timeline of BIM adoption in Finland is shown in Figure 4. Many government agencies and companies are involved in R&D work on BIM and work to promote BIM throughout the country. According to a research conducted in 2007, the BIM usage and BIM applications in compliance with IFC was estimated to be 33% (Kiviniemi, 2007; Wong et al., 2009). One hundred and eight BIM projects were completed within the technology programme, namely Sara – Value Networks in Construction (2003–2007), launched by TEKES, the Finnish Funding Agency for Technology and Innovation (Arayici and Aouad, 2010; TEKES, 2008).This research is part of the PhD research project ‘Creation of the Building Information Modelling (BIM) Roadmap for the Turkish Construction Sector’ (Project ID: 2016-05-01-DOP01), supported by Yıldiz Technical University Coordinatorship of Scientific Research Projects

Parameters derived from compound muscle action potential scan for discriminating amyotrophic lateral sclerosis-related denervation
No full textWOS: 000479282600001PubMed ID: 31330055Artuğ, Tuğrul (Arel Author)Introduction The objective of this study was to determine compound muscle action potential (CMAP) scan parameters and MScanFit motor unit number estimation (MUNE) in patients with amyotrophic lateral sclerosis (ALS) and to compare the results in the abductor pollicis brevis (APB) to those in the abductor digiti minimi (ADM). Methods CMAP scans were recorded from the APB and ADM in 35 patients with ALS and 21 controls. MScanFit MUNE, neurophysiological index (NI), step%, returner%, and D50 were calculated. Results CMAP scan parameters including the returner%, MScanFit MUNE, and NI can distinguish ALS with high sensitivity and specificity. The electrophysiological parameters, with the exception of D50 (the number of largest consecutive differences of recorded responses generating 50% of maximum CMAP), showed more pronounced changes in the APB than in the ADM, even though most of the patients had normal APB/ADM amplitude ratios. Discussion CMAP scan parameters and MScanFit MUNE can be used in the evaluation of denervation and reinnervation and may herald the "split hand" in ALS
Information retrieval using the reduced row echelon form of a term-document matrix
No full textZontul, Metin (Arel Author)It is getting more difficult to retrieve relevant information regarding the user input query due to the large amount of information in the web. Unlike the conventional information retrieval (IR) algorithms, this study presents a new algorithm – reduced row echelon form IR method (rrefIR) – with higher average similarity precision to get more relevant and noise-free documents. For dimension reduction in the proposed algorithm, singular value decomposition (SVD) is applied on the reduced row echelon form – obtained by utilizing Gauss-Jordan method – of the covariance of term-document matrix (TDM). The rrefIR algorithm outperforms the LSI and COV algorithms with respect to Jaro-Winkler, Overlap, Tanimoto and Jaccard similarity measures in the means of average similarity precision. The physical reason for the better IR performance is the linear independent basis vectors set obtained by Gauss-Jordan operation. This basis set can be considered as the generating roots of the vector space spanned by TDM. Utilizing these vectors increases the latent semantic charateristics of the SVD phase of the proposed IR algorithm. © 2019 Taiwan Academic Network Management Committee. All rights reserved
Measurement of the absolute branching fractions of Lambda(+)(c) -> Lambda eta pi(+) and Sigma(1385) (+) eta
No full textKolcu, Onur Buğra (Arel Author)We study the decays Lambda(+)(c) -> Lambda eta pi(+) and Sigma(1385)(+)eta based on Lambda(+)(c)(Lambda) over bar (c) pairs produced in e(+)e(-) collisions at a center-of-mass energy of root s = 4.6 GeV, corresponding to an integrated luminosity of 567 pb(-1). The data sample was accumulated with the BESIII detector at the BEPCII collider. The branching fractions are measured to be beta(Lambda(+)(c) -> Lambda eta pi(+)) = (1.84 +/- 0.21 (stat) +/- 0.15(syst))% and B(Lambda(+)(c) -> Sigma(1385)(+) eta) = (0.91 +/- 0.18 (stat) +/- 0.09 (syst))%, constituting the most precise measurements to date

No full textKolcu, Onur Buğra (Arel Author)By analyzing (448.1 +/- 2.9) x 10(6) psi(3686) events collected with the BESIII detector operating at the BEPCII collider, the decays of chi(c)(J) -> 4K(S)(0) (J = 0, 1, 2) are observed for the first time with statistical significances of 26.5 sigma, 5.9 sigma and 11.4 sigma, respectively. The product branching fractions of psi(3686) -> gamma chi(cJ), chi(cJ) -> 4K(S)(0 )are presented, and the branching fractions of chi(cJ) -> 4K(S)(0) decays are determined to be B-chi c0 -> 4KS0 = (5.76 +/- 0.34 +/- 0.38) x 10(-4), B-chi c1 -> 4KS0 = (0.35 +/- 0.09 +/- 0.03) x 10(-4) and B-chi c2 -> 4KS0( )= (1.14 +/- 0.15 +/- 0.08) x 10(-4), where the first uncertainties are statistical and the second are systematic, respectively
A patient with anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA syndrome) and 13 live births
No full textYolcu, Mustafa (Arel Author) --- PubMed ID: 30729975Anomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) or Bland-White-Garland syndrome is a rarely seen congenital anomaly. Adult and infantile types are defined according to the degree of collateral development between the left coronary artery (LCA) and right coronary artery (RCA). If left untreated, ALCAPA has a 90% mortality rate in the first year of life, primarily due to myocardial ischaemia and heart failure. The degree of collateral development and the related LCA perfusion in ALCAPA syndrome determine the occurrence of symptoms. Herein, we present a case of a female patient who had previously, without any symptoms, given live birth to 13 babies. She had been experiencing exertional angina, which started long after the delivery of her 13th child. Since our patient had well-developed collaterals to the LCA, she was asymptomatic and able to give birth to the children via the vaginal route without any problems. Having well-formed collateral vessels between the RCA and LCA may prevent patients from developing symptoms, and even stressful conditions such as pregnancy may be tolerable
Particle swarm optimization-based collision avoidance
No full textCollision risk assessment and collision avoidance of vessels have always been an important topic in ocean engineering. Decision support systems are increasingly becoming the focus of many studies in the maritime industry today as vessel accidents are often caused by human error. This study proposes an anticollision decision support system that can determine surrounding obstacles by using the information received from radar systems, obtain the position and speed of obstacles within a certain time period, and suggest possible routes to prevent collisions. In this study we use a neural network to predict the subsequent positions of surrounding vessels, a fuzzy logic system to obtain the risk of collision, and a particle swarm optimization algorithm to find the safe and shortest path for collision avoidance
Frequency, voltage and illumination interaction with the electrical characteristics of the CdZnO interlayered Schottky structure
No full textTaşçıoğlu, İlke (Arel Author)cadmium-zincoxide (CdZnO) interlayered metal-semiconductor structure was examined by capacitance and conductance versus voltage data in dark and under 250W illumination at 100kHz, 500kHz and 1MHz frequencies, respectively. The effectuality of the frequency, applied voltage, illumination, and series resistance on the electrical parameters was discussed in detail. The increase in the frequency led to the decrement in capacitance and conductance and the increment in the illumination generally led to the increment in capacitance and conductance. An abnormal behavior was detected in the accumulation region of the C-V plots at 500kHz and 1MHz due to the inductive phenomenon of device. The effect of illumination intensity reduces the R-i values in the inversion region while enhances them in the depletion and accumulation region for 1MHz. Additionally, the series resistance values decrease with increasing frequency due to the specific dispersion of localized interface states. As a consequence of the experimental results, a remarkable interaction was realized between the electrical parameters and the illumination, frequency and applied biases
