Tracking the Built Status of MEP Works: Assessing the Value of a Scan-vs-BIM System

AbstractMechanical, electrical, and plumbing (MEP) works constitute a large portion of construction costs and thus need to be appropriately tracked. Assessment of the built status of MEP works in construction projects is however typically limited to subcontractor claims augmented and contrasted with periodic manual inspection. A more detailed manual inspection is costly and not considered worthwhile on most projects. Within a Scan-vs-BIM object recognition framework, three-dimensional laser scanning and project 3D/4D BIM models jointly offer the opportunity for a frequent, detailed, and semantically rich assessment of as-built status of construction projects at a cost that continues to decline. This potential has already been demonstrated for tracking structural works, but remains to be assessed in regard to other work sections, in particular MEP works. This paper explores that opportunity. A Scan-vs-BIM processing system is described with some enhancements over previous works. It is then tested with a re.
A retrospective analysis of clinical profile of patients with cancer cervix in a rural medical college in Karnataka

Cancer cervix is most common cause of cancerous deaths in females especially in developing countries. The pre-invasive stage of cervical cancer lasts for a long period and a small proportion progresses to an invasive lesion. In Indian set up, majority of the patients are presenting with an invasive lesion. To describe the clinical profile of patients presented with cervical cancer and to describe various treatments received by those patients. : The present study is a retrospective observational study done on confirmed cases of carcinoma cervix who attended rural medical college in Karnataka. Clinical records of the patients, who presented between November 2019 and November 2020 and were diagnosed with cervical cancer, were retrieved. The data related to demographic and clinical variables like age, socioeconomic status, education, symptoms, clinical staging, treatment and histopathology report were recorded. Data collected were entered in Microsoft Excel Office 2007and data analysed. Data were presented using descriptive statistics. The data was expressed in the form of frequencies and percentagesA total of 30 patients with the median age of 46 years were studied. Most common presentation was post coital bleeding (40%) followed by white discharge per vagina in 33%. Majority were under low socioeconomic status (70%). 60% presented in stage II and 30% in stage I. Chemoradiation was treatment of choice in 60% followed by surgery in 33% and 7% were lost to follow up. On histopathology, majority had squamous cell carcinoma (70%). The appropriate management of Cervical intraepithelial neoplasia(CIN) can prevent invasive cervical cancer. In this study most of them presented in advanced stage which could have been prevented with the regular screening and awareness among women in the reproductive age group. : Detection of pre invasive lesions or in situ cases remains important key to decreasing cervical cancer morbidity and mortality.
INFLUENCE OF CULTURE ON THE PERCEPTION OF A WEBSITE A Three Countries Study

The purpose of the research is to examine how users perceive the cultural origin of a Website, even though the site was developed using principles of usability and trying to minimize culture shock. A B2C site been developed using usability principles. English language is used in order to remove traces of the companys cultural background that designed and implemented the site. The site sells records from independent and small music labels. The survey was based on a sample of convenience that cannot be regarded as homogenous. The participants from U.S, Mexico and Spain are not necessarily music buyers and collectors of records, consequently the user characteristics of collectors are not reflected in the site preferences. It was found that Hofstede's Cultural values of collectivism and risk aversion have been consistent. The usability-engineering design of a site helps to make it more efficient and reduce fears, although, this is not enough.
Ultra-low-power quadrature VCO for 2.4 GHz-band IEEE 802.15.4 Standard

A fully integrated quadrature voltage-controlled oscillator (QVCO) for IEEE 802.15. 4 transceivers is presented. The QVCO supports the 2.4 GHz unlicensed industrial, scientific and medical (ISM) band. The proposed QVCO generates 2.25–2.9 GHz covering 2.4 GHz transceivers. Quadrature coupling between the VCO cores is achieved using common source transistors which have their drains directly connected to the supply voltage. By using this structure, the effect of 1/f noise up-conversion in the phase-noise performance could be reduced. The QVCO achieves a measured phase noise of −116.74 dBc/Hz at 1 MHz offset with a centre frequency of 2.5 GHz. The proposed QVCO consumes 0.55 mW from a 0.45 V supply voltage and is implemented in a standard 0.13 μm CMOS process with a core area of 0.315 mm2.
Multibit Sigma - Delta A/D converter incorporating a novel class of dynamic element matching techniques

A dynamic element matching technique is applied to multibit sigma-delta modulators. The approach translates the harmonic distortion components of a nonideal digital-to-analog converter (DAC) in the feedback loop of a sigma-delta modulator to high-frequency components, which can then be filtered out by the decimation filter. Computer simulations have confirmed that with this approach a third-order sigma-delta modulator employing a 3-bit forward ADC, a 3-bit feedback DAC with a random mismatch of 0.1% can achieve a 104-dB (17+bit) dynamic range and a harmonic distortion below 100 dB, with an oversampling ratio of 64. The technique does not generate any tone in the passband. >
Hybrid Algorithm for Anomaly Removal in Time Series Data Mining

Time series data are significant and are derived from temporal data, which involve real numbers representing values collected regularly over time. Time series have a great impact on many types of data. However, time series have anomalies. We introduce hybrid algorithm named novel matrix profile (NMP) to solve the all-pairs similarity search problem for time series data. The proposed NMP inherits the features from two state-of-the art algorithms: similarity time-series automatic multivariate prediction (STAMP), and short text online microblogging protocol (STOMP). The proposed algorithm caches the output in an easy-to-access fashion for single- and multidimensional data. The proposed NMP algorithm can be used on large data sets and generates approximate solutions of high quality in a reasonable time. The proposed NMP can also handle several data mining tasks. It is implemented on a Python platform. To determine its effectiveness, it is compared with the state-of-the-art matrix profile algorithms i.e., STAMP and STOMP. The results confirm that the proposed NMP provides higher accuracy than the compared algorithms.
Generalized image method with application to the thermal modeling of power devices and circuits

A new analytical thermal model of multilayer substrates is presented. Based on a generalization of the method of images, the model is straightforward to implement and allows a clearer understanding of the effect of geometric and material parameters on the temperature field. Approximate expressions for the thermal resistance in multilayer substrates are derived for the first time. The generalized image method can be applied to solve similar problems which involve the solution of the Laplace equation in composite domains consisting of several layers. Typical examples are problems of the electrostatics and ohmic conduction phenomena.
Review on Deep Learning Methods for Chest X-Ray based Abnormality Detection and Thoracic Pathology Classification

Backed by more powerful computational resources and optimized training routines, deep learning models have proven unprecedented performance and several benefits to extract information from chest X-ray data. This is one of the most common imaging exams, whose increasing demand is reflected in the aggravated radiologists’ workload. Consequently, healthcare would benefit from computer-aided diagnosis systems to prioritize certain exams and further identify possible pathologies. Pioneering work in chest X-ray analysis has focused on the identification of specific diseases, but to the best of the authors' knowledge no paper has specifically reviewed relevant work on abnormality detection and multi-label thoracic pathology classification. This paper focuses on those issues, selecting the leading chest X-ray based deep learning strategies for comparison. In addition, the paper discloses the current annotated public chest X-ray databases, covering the common thorax diseases.
Model-data comparison of total dose experiment on KITSAT-1

Using a model developed for temperature-dependent irradiations, we analyze the results of the KITSAT-1 total dose experiment (TDE) accumulated during more than two years from September 1992 through December 1994. Monte Carlo simulations are adopted for the calculation of effective shielding thickness of the spacecraft at the position of TDE. With parameters obtained from a laboratory Co/sup 80/ /spl gamma/-ray experiment, the model reproduces the observed threshold voltage changes quite successfully, including peculiar oscillations caused by temperature variations. The total dose received by TDE is estimated to be about 40% larger than the NASA predictions, in general agreement with the APEXRAD model.
Reduced-complexity model for the impact of anthropogenic CO2 emissions on future glacial cycles

Abstract. We propose a reduced-complexity process-based model for the long-term evolution of the global ice volume, atmospheric CO2 concentration, and global mean temperature. The model's only external forcings are the orbital forcing and anthropogenic CO2 cumulative emissions. The model consists of a system of three coupled non-linear differential equations representing physical mechanisms relevant for the evolution of the climate–ice sheet–carbon cycle system on timescales longer than thousands of years. Model parameters are calibrated using paleoclimate reconstructions and the results of two Earth system models of intermediate complexity. For a range of parameters values, the model is successful in reproducing the glacial–interglacial cycles of the last 800 kyr, with the best correlation between modelled and global paleo-ice volume of 0.86. Using different model realisations, we produce an assessment of possible trajectories for the next 1 million years under natural and several fossil-fuel CO2 release scenarios. In the natural scenario, the model assigns high probability of occurrence of long interglacials in the periods between the present and 120 kyr after present and between 400 and 500 kyr after present. The next glacial inception is most likely to occur ∼50 kyr after present with full glacial conditions developing ∼90 kyr after present. The model shows that even already achieved cumulative CO2 anthropogenic emissions (500 Pg C) are capable of affecting the climate evolution for up to half a million years, indicating that the beginning of the next glaciation is highly unlikely in the next 120 kyr. High cumulative anthropogenic CO2 emissions (3000 Pg C or higher), which could potentially be achieved in the next 2 to 3 centuries if humanity does not curb the usage of fossil fuels, will most likely provoke Northern Hemisphere landmass ice-free conditions throughout the next half a million years, postponing the natural occurrence of the next glacial inception to 600 kyr after present or later.

The accountancy of marketisation: Fictional markets in housing land supply

This article investigates the performative role of accountancy in embedding market mechanisms in public services. Drawing on the work of Karl Polanyi, it argues that marketisation can be understood as a work of calculative modelling in which the fiction of a self-regulating market is propagated through the concealment of the social and political practices on which it depends. Exploring this thesis in the marketisation of housing land supply, the article provides a forensic study of an accountancy procedure called the Housing Delivery Test that modelled an ideal housing market in the English land-use planning system. The study points to the importance of Polanyi's analysis in theorising the performativity of calculative practices in the project of marketisation, not as creating the economy they describe but in fashioning a fictional market.
The Influence of Early Sound Direction on Apparent Source Width (ASW)

t is now generally accepted that there are two spatial effects in concert halls: apparent source width (ASW) and listener envelopment (LEV). Barron have proposed the early lateral sound energy fraction (LFE) as an objective measure for apparent source width. But this measure takes no account of asymmetry role between the early sounds from front and behind. The purpose of this study is to investigate the relation between the arrival direction of early sound and ASW. Experiments using sound field simulated in an anechoic room confirm that early-arriving sound from in front of listener give more contribution to ASW than symmetrical direction behind listener. As the direction of arrival approaches between 45o to 60o from straight ahead in the horizontal plane the ASW approaches a maximum.
Can serum 8-hydroxy-2'-deoxyguanosine levels reflect the severity of pulmonary arterial hypertension?

OBJECTIVE Oxidative stress plays a pivotal role in the pathogenesis of pulmonary arterial hypertension. 8-Hydroxy-2'-deoxyguanosine is a sensitive biomarker that reflects the degree of oxidative damage to DNA. We investigated whether serum 8-Hydroxy-2'-deoxyguanosine is a clinically useful biomarker for the severity of pulmonary arterial hypertension. METHODS We measured serum 8-Hydroxy-2'-deoxyguanosine levels in 25 patients (age 37±13 years, 68% women) diagnosed with idiopathic pulmonary arterial hypertension, familial pulmonary arterial hypertension, or pulmonary arterial hypertension associated with congenital heart disease. The severity of pulmonary arterial hypertension was evaluated by six-min walking distance, World Health Organization functional class, and serum brain natriuretic peptide levels. Age and gender-matched 22 healthy subjects served as the control group. RESULTS The comparison of 8-Hydroxy-2'-deoxyguanosine levels between patients and controls was not statistically different [(19.86±9.79) versus (18.80±3.94) ng/mL, p=0.622)]. However, there was a significant negative correlation between 8-Hydroxy-2'-deoxyguanosine levels and six-min walking distance (r= -0.614, p=0.001). Additionally, serum 8-Hydroxy-2'-deoxyguanosine levels in patients with functional class III-IV were significantly higher than those with functional class I-II (functional class III-IV 32.31±10.63 ng/mL versus functional class I-II 16.74±6.81 ng/mL, respectively, p=0.003). CONCLUSION The 8-Hydroxy-2'-deoxyguanosine levels were significantly correlated with exercise capacity (six-min walking distance) and symptomatic status (functional class), both of which show the severity of pulmonary arterial hypertension in patients.
Neuro‐fuzzy synthesis of flight control electrohydraulic servo

Presents a switching type neuro‐fuzzy control synthesis. The control algorithm supposes as a component part a neurocontrol designed to optimize a performance index. Whenever the neurocontrol saturates or a certain performance parameter of the system decreases, the scheme of control switches to a feasible and reliable fuzzy logic control. Describes the procedure of return to the optimizing neurocontrol which is essential. This methodology of control synthesis ensures antisaturating, antichattering and robustness properties of the controlling system, as illustrated by numerical simulation in the case of a primary flight controls electrohydraulic servo actuator
Bondability Problems Associated with the Ti-Pt-Au Metallization of Hybrid Microwave Thin Film Circuits

The cause for unacceptable bonding behavior of a new high-resolution, close-tolerance hybrid thin film circuit metals system was investigated. The conductor/resistor technology was developed at Hewlett-Packard for microwave applications. It consisted of Ti-PtAu/Ta 2 N where conductors were defined by a sputter etching process with the aid of an auxiliary Ti mask at the Au surface. The cause of the bondability problem was determined by Auger electron spectroscopy (AES) to be residual Ti-O compound at the conductor surface. An evaluation scheme which specifically addressed bond acceptability and integrity with respect to mechanical, visual, and reliability testing was developed. Types of bonds and the methods of testing associated with each bond type were investigated in terms of the apparent bond failure mechanism. Various wire and ribbon bonding processes were examined. A series of bond evaluation techniques which include both qualitative and quantitative ball shear and wire pull tests were performed. A qualitative shear test of the thermocompression Au ball bond was shown to be the most reliable indicator of bond integrity and acceptability. Bond stick rates and wire pull test results were found to be, in themselves, unreliable yardsticks for determining bond quality. Additional information was obtained from AES samples with excellent (close to 100 percent) stick rates but poor shear test characteristics. Various surface treatments to enhance bondability were investigated. Three different concentrations of H 2 O:HF:HNO 3 solutions as well as a Au etch were examined. A Ti etch consisting of H 2 O, HF, and HNO 3 , (10:1:1, respectively) was selected and easily implemented as a final processing step before bonding. Results comparing as-processed with Ti etched (10:1:1) circuits revealed a marked increase in stick rate (from ~50 to ~100 percent), ball bond shear strength and wedge bond pull strength, without altering existing bonding processes currently employed in production. Furthermore, environmental testing of exposed bonds on Ti etched (10:1:1) conductor surfaces confirmed bond integrity.

Progress in understanding of Indian Ocean circulation, variability, air–sea exchange, and impacts on biogeochemistry

Abstract. Over the past decade, our understanding of the Indian Ocean has advanced through concerted efforts toward measuring the ocean circulation and air–sea exchanges, detecting changes in water masses, and linking physical processes to ecologically important variables. New circulation pathways and mechanisms have been discovered that control atmospheric and oceanic mean state and variability. This review brings together new understanding of the ocean–atmosphere system in the Indian Ocean since the last comprehensive review, describing the Indian Ocean circulation patterns, air–sea interactions, and climate variability. Coordinated international focus on the Indian Ocean has motivated the application of new technologies to deliver higher-resolution observations and models of Indian Ocean processes. As a result we are discovering the importance of small-scale processes in setting the large-scale gradients and circulation, interactions between physical and biogeochemical processes, interactions between boundary currents and the interior, and interactions between the surface and the deep ocean. A newly discovered regional climate mode in the southeast Indian Ocean, the Ningaloo Niño, has instigated more regional air–sea coupling and marine heatwave research in the global oceans. In the last decade, we have seen rapid warming of the Indian Ocean overlaid with extremes in the form of marine heatwaves. These events have motivated studies that have delivered new insight into the variability in ocean heat content and exchanges in the Indian Ocean and have highlighted the critical role of the Indian Ocean as a clearing house for anthropogenic heat. This synthesis paper reviews the advances in these areas in the last decade.
Quality cost in the construction industry-preliminary findings in Malaysia

One of the key areas being emphasis in ISO 9001 Quality Management System (QMS) is performance measurement towards continual improvement. Among the primary measuring tools is quality cost approach. Quality cost has been well practice in manufacturing sector but slowly gain its importance in construction industry. In fact Project Management Body of Knowledge (PMBOK) has reckoned quality cost as one of the tool and technique in few of its management processes. In view of such circumstances that has prompted an effort to undertake a study to ascertain the level of knowledge and practice on quality cost in Malaysian construction landscape. The targeted group of respondents was the personnel in the project management team. Capitalizing Construction Industry Development Board (CIDB) National Electronic Tendering Initiatives (NETI) road shows which were held in year 2007 throughout the country, the author was able to garner 263 respondents representing the project management team. Subsequently the data gathered from the completed forms were analyzed using Statistical Package for Social Science (SPSS) software. General findings indicated that the level of knowledge and practice on quality cost among the project management team were relatively low. One of the main contributing factors was poor knowledge in the area related to quality cost. Despite of such scenario most of the respondents showed their interest in acquiring knowledge in the field of quality cost. Hence quality cost approach is at the infancy stage in Malaysian construction industry.
