Deconstruction waste management through 3d reconstruction and bim: a case study
Authors: Ge Xin Janet , Livesey Peter , Wang Jun , Huang Shoudong , He Xiangjian , Zhang Chengqi 
Published: July 2017

AbstractThe construction industry is responsible for 50% of the solid waste generated worldwide. Governments around the world formulate legislation and regulations concerning recycling and re-using building materials, aiming to reduce waste and environmental impact. Researchers have also been developing strategies and models of waste management for construction and demolition of buildings. The application of Building Information Modeling (BIM) is an example of this. BIM is emergent technology commonly used to maximize the efficiency of design, construction and maintenance throughout the entire lifecycle. The uses of BIM on deconstruction or demolition are not common; especially the fixtures and fittings of buildings are not considered in BIM models. The development of BIM is based on two-dimensional drawings or sketches, which may not be accurately converted to 3D BIM models. In addition, previous researches mainly focused on construction waste management. There are few studies about the deconstruction waste management focusing on demolition. To fill this gap, this paper aims to develop a framework using a reconstructed 3D model with BIM, for the purpose of improving BIM accuracy and thus developing a deconstruction waste management system to improve demolition efficiency, effective recycling and cost savings. In particular, the developed as-built BIM will be used to identify and measure recyclable materials, as well as to develop a plan for the recycling process.
Crowdsourcing BIM-guided collection of construction material library from site photologs
Authors: Han Kevin , Golparvar-Fard Mani 
Published: July 2017

Abstract
Background
With advances in technologies that enabled massive visual data collection and BIM, the AEC industry now has an unprecedented amount of visual data (e.g., images and videos) and BIMs. One of the past efforts to leverage these data includes the Construction Material Library (CML) that was created for inferring construction progress by automatically detecting construction materials. CML has a limited number of construction material classes because it is merely impossible for an individual or a group of researchers to collect all possible variations of construction materials.

Methods
This paper proposes a web-based platform that streamlines the data collection process for creating annotated material patches guided by BIM overlays.

Result
Construction site images with BIM overlays are automatically generated after image-based 3D reconstruction. These images are deployed on a web-based platform for annotations.

Conclusion
The proposed crowdsourcing method using this platform has potential to scale up data collection for expanding the existing CML. A case study was conducted to validate the feasibility of the proposed method and to improve the web interface before deployment to a public cloud environment.
Time-to-depth conversion and velocity estimation by image-wavefront propagation
Authors: Sadala Valente Leandro da S. , Santos Henrique B. , Costa Jessé C. , Schleicher Jörg 
Published: July 2017

A new strategy for time-to-depth conversion and interval-velocity estimation is based entirely on image-wavefront propagation without the need to follow individual image rays. The procedure has three main features: (1) It computes the velocity field and the traveltime directly, allowing us to dispense with dynamic ray tracing; (2) it requires only the knowledge of the image wavefront at the previous time step; and (3) it inherently smooths the image wavefront, inhibiting the formation of caustics. As a consequence, the method tends to be faster than the usual techniques and does not carry the constraints and limitations inherent to common ray-tracing strategies. Synthetic tests using a Gaussian velocity anomaly as well as the Marmousi velocity model, and two smoothed versions of it show the feasibility of the method. A field-data example demonstrates the use of different numerical procedures. Our results indicate that the present strategy can be used to construct reasonable depth-velocity models that can be used as reliable starting models for velocity-model building in depth migration or for tomographic methods.
Differentiation of chronic total occlusion and subtotal occlusion of the femoropopliteal artery—role of retrograde flow sign and collateral circulation on CT angiography images
Authors: Zhang Shujun , Su Yanfei , Chen Haisong 
Published: July 2017

Objective:
To study the value of a retrograde flow sign and the collateral circulation on CT angiography (CTA) for the differential diagnosis of chronic total occlusion from subtotal occlusion of the femoropopliteal artery (FPA).

Abstract
50 patients with obstruction of the FPA underwent CTA and digital subtraction angiography examinations of the lower limbs. The frequency of a retrograde flow sign and collateral circulation on CTA in chronic total and subtotal occlusion was noted and analyzed, with the results of digital subtraction angiography as a standard to judge total or subtotal occlusion. The decreasing CT value from the distal to proximal direction on CTA suggests the existence of retrograde flow.

Results:
There were significant differences in the occurrence rates of a retrograde flow sign on CTA in the chronic total and subtotal obstruction groups (X2 = 13.1, p &lt; 0.05), as well as a collateral circulation sign (X2 = 13.5, p &lt; 0.05). Employing both the retrograde flow sign and the collateral circulation sign to diagnose chronic total obstruction of the FPA had a sensitivity of 92.3% and specificity of 89.8%.

Conclusion:
The retrograde flow sign combined with a collateral circulation sign is of great clinical value for differentiation of chronic total stenosis from severe stenosis (subtotal occlusion) of the FPA.

Advances in knowledge:
A retrograde flow sign combined with a collateral circulation sign is of great clinical value to differentiate between chronic total stenosis and severe stenosis (subtotal occlusion) of the FPA.

Published: July 2017

Objective:
The purpose of this study is to review simulation CT scans and evaluate their diagnostic value in patients treated with adjuvant radiotherapy for pancreatic adenocarcinoma.

Methods:
73 patients who had undergone simulation CT scans for adjuvant radiotherapy in pancreatic adenocarcinoma were reviewed. All simulation CT scans were reviewed by professional abdominal radiologists, who compared the images with corresponding prior CT scans to identify new lesions. Newly detected cancer-related lesions were classified into one of three categories: distant metastasis, locoregional recurrence and indeterminate lesions. Indeterminate lesions were reviewed for malignancy during follow-up imaging work-ups.

Results:
Of 73 patients, distant metastasis, locoregional recurrence and indeterminate lesions were found in 4 (5.5%), 5 (6.8%) and 32 patients (43.8%), respectively. Among 32 indeterminate lesions, 24 (75.0%) were soft tissue lesions neighbouring the superior mesenteric vessels. Follow-up PET-CT and diagnostic CT scans revealed that 43.7% of indeterminate lesions were malignant presenting local failures. The 3-year overall survival was significantly higher among patients who had no cancer-related lesions than among who did have such findings (44.8% vs 10.8%, p = 0.002).

Conclusion:
Professional review of simulation CT scans have ample diagnostic value as they help detect early progressions or potential failures in patients treated with adjuvant radiotherapy for pancreatic adenocarcinoma. Simulation CT scans should be carefully reviewed before the delivery of adjuvant radiotherapy.

Advances in knowledge:
Generally, simulation CT scan has been known to provide limited diagnostic values and clinical impact. However, the results of this study showed a high detection rate of cancer-related lesions, which could potentially affect subsequent treatment strategies in patients with pancreatic adenocarcinoma.
A computer-aided diagnosis (CAD) scheme for pretreatment prediction of pathological response to neoadjuvant therapy using dynamic contrast-enhanced MRI texture features
Authors: Giannini Valentina , Mazzetti Simone , Marmo Agnese , Montemurro Filippo , Regge Daniele , Martincich Laura 
Published: July 2017

Objective:
To assess whether a computer-aided, diagnosis (CAD) system can predict pathological Complete Response (pCR) to neoadjuvant chemotherapy (NAC) prior to treatment using texture features.

Methods:
Response to treatment of 44 patients was defined according to the histopatology of resected tumour and extracted axillary nodes in two ways: (a) pCR+ (Smith’s Grade = 5) vs pCR− (Smith’s Grade &lt; 5); (b) pCRN+ (pCR+ and absence of residual lymph node metastases) vs pCRN−. A CAD system was developed to: (i) segment the breasts; (ii) register the DCE-MRI sequence; (iii) detect the lesion and (iv) extract 27 3D texture features. The role of individual texture features, multiparametric models and Bayesian classifiers in predicting patients’ response to NAC were evaluated.

Results:
A cross-validated Bayesian classifier fed with 6 features was able to predict pCR with a specificity of 72% and a sensitivity of 67%. Conversely, 2 features were used by the Bayesian classifier to predict pCRN, obtaining a sensitivity of 69% and a specificity of 61%.

Conclusion:
A CAD scheme, that extracts texture features from an automatically segmented 3D mask of the tumour, could predict pathological response to NAC. Additional research should be performed to validate these promising results on a larger cohort of patients and using different classification strategies.

Advances in knowledge:
This is the first study assessing the role of an automatic CAD system in predicting the pathological response to NAC before treatment. Fully automatic methods represent the backbone of standardized analysis and may help in timely managing patients candidate to NAC.
Effect of stand structure on density of pine and spruce wood in myrtillus forest type
Authors: Данилов  , Danilov Dmitriy , Смирнов  , Smirnov A. 
Published: July 2017

Mixed stands of spruce and pine of myrtillus y forest types occupy large areas of the forest
fund of the Leningrad region. For the theory and practice of forestry it is important to know the impact
of plantations on the density of wood in bunk mixed spruce-pine stands. In mixed stands of
pine and spruce disks and cores of wood species were selected from the model tree to determine the
basic density by the method of maximum water capacity. The study of basic wood density of pine
and spruce in the coniferous bunk stands revealed that its rates are higher for both species in the
mixed forest stand than in pure coniferous plantations in the region of the study. With the predominance
of pines in the stand composition, its wood density is higher than in stands dominated by
spruce. Density of pinewood increases from smaller to larger classes of stand diameters. Variability
of wood density by diameter of trunk is higher in spruce than in pine in mixed stands. In stands, after
cutting dilutes the density of pinewood is lower than in the plantation, which is not passed with
felling. In the bunk spruce-pine the stand, to the age of maturity, larger mass of stem wood of coniferous
species is formed than in the pure one-tier stands of pine or spruce. Developed regression
equations depending on the density of the wood at a height of 1.3 m to the average density of trunk
allow for a more accurate assessment of this parameter in mixed stands than previously published
equations for pure stands of myrtillus forest types for the study area.
Equiradial designs under changing axial distances, design sizes and varying center runs with their relationships to the central composite designs
Authors: Iwundu Mary , Onu Henry 
Published: July 2017

In assessing the preferences of equiradial designs based on design size, axial distance and number of center points in relation to the central composite designs, D-absolute deviation (D-AD) and G-absolute deviation (G-AD) are proposed as new design measures of closeness of experimental designs. Each absolute deviation is positive or zero. The G-absolute deviation is zero or approximately zero at equals 1 center point. For greater than 1, G-absolute deviation decreases for increasing values of . On the other hand, the D-absolute deviation decreases as the design size increases. Designs having G-AD values of zero or approximately zero are identical or near identical in G-optimality properties. Also, designs having D-AD values of zero or approximately zero are identical or near identical in D-optimality properties. It is conjecturally hoped that at some increased design size, the equiradial designs and the central composite designs, having same axial or radial distance will coincide (be identical) in their properties, with D-AD value of zero or approximately zero.

Published: July 2017

Abstract
The paper includes results of economic calculation until 2020 regarding adaptations of the algorithm model of forecasting supply of spatial economic objects for planning the development of the Latvian high-end industrial market space. Scientific discussion concerns the average temperature increase as a determinant ratio and the definition of spatial economics developed by the authors The research focuses on the changes in climatic conditions, which may have an impact on the country’s economic development priorities. The paper also reflects on assessment of regional specialization of the leading entrepreneurial activities in Latvia and the Baltic States. It is mainly based on the empirical study of scientific literature. The authors apply the following methods: decision-making, analysis of primary and secondary sources, the Gini coefficient of Regional Specialization, the Gini coefficient of Geographical Concentration, logical approach and comparisons, systems and dynamic factor analysis, expert analysis, mathematical statistical methods. Main conclusions state that Latvia would continue regional development, maintain division of industrial capacities and decrease of Riga’s industrial agglomeration. Agriculture will develop intensively. Increase in high-class industrial property stock is partly conditioned by the high-quality manufacturing needs, as well as logistics and service needs. The calculated level of that stock is 772,300 sq.m until 2020. In fact, Latvia demonstrates low regional specialization rates for agriculture and manufacturing. The authors stress importance of development of the appropriate infrastructure in creating competitive local business environment in the Latvian cities.

Published: July 2017

Abstract
The article presents theoretical foundations of a two-diode equivalent model of a photovoltaic cell/module (PV), together with calculation procedures. A physical interpretation of individual components of an equivalent model was presented. Its practical application in predicting efficiency of operation of various PV cells and modules in low insulation conditions was demonstrated. The obtained predictions were verified with the actual results of their operation in open space (outdoor). The practical suitability of the “model” in early detection of ageing phenomena, such as, for example, absorber degradation taking place in PV modules, was demonstrated. The article was prepared on the basis of the results of testing five different PV modules with various constructions, made of different materials and absorbers, such as: c-Si, mc-Si, CIS, a-Si_SJ, a-Si_TJ. The used measurement data were collected during the 16-year period of the experimental PV modules testing system operation in University of Opole, equipped with a data acquisition system.
Energy Willow From Experimental Plantation as a Potentially Clean Energy Source
Authors: Janas Monika , Zawadzka Alicja 
Published: July 2017

Abstract
Energy willow as a species with broad adaptation possibilities, large production capacity and a wide range of applications, takes a special place among the plants grown for energy production. In this work an analysis was conducted in respect of the usefulness of this type of wood from experimental plantations as a clean source of energy generated in the combustion process. The heat of combustion and net calorific value of dry matter of energy willow wood, including selected sorts and classes of thickness were determined. Energy willow has a natural ability to accumulate heavy metals which are oxidized during the combustion process or remain in the ash, and consequently repollute the environment. In order to determine the environmental impact the content of heavy metals was examined in energy willow wood and in the soil of the experimental plantation. Metal concentrations were determined by the Atomic Absorption Spectrometry method (AAS). Results of the tests confirmed a close relationship between the heat of combustion, calorific value and wood thickness as well as its location in the tree structure. Furthermore, very large differences were found in the content of heavy metals in the samples of both willow wood and soil. The levels of heavy metal content in the wood of energy willow determine the agricultural use of ashes produced during combustion.
PVP Based Materials: Biodegradation in Different Environments
Authors: Vanharova Ludmila , Julinova Marketa , Slavik Roman 
Published: July 2017

Abstract
The research deals with biodegradation of films prepared from polyvinylpyrrolidone and polylactic acid (PVP/PLA). Biodegradation of PVP/PLA films was supported by the following additives: 1-methyl-2-pyrrolidone, 1-octyl-2-pyrrolidone, acrylamide and N-acetyl-L-phenylalanine according to the previous study. The films were prepared by a solvent casting technique. Biodegradation was observed using the respirometric method in different environments. The films subjected to biodegradation were analyzed by scanning electron microscopy and Fourier transform infrared spectroscopy. It was found that the films are substantially degraded, but not in the biological way; PVP was quickly removed in presence of water because of its easy solubility. In contrast, this fact could support biodegradation of PLA, which becomes more available for microorganisms when PVP leaves PLA matrix.
