Computer-aided design of cyber-physical building systems
Authors: Chelyshkov Pavel 
Published: May 2019

At present, an increasing number of researchers and specialists in the construction industry come to the opinion that it is advisable to use a number of technologies (BIM, Smart City, Big Data, IOT and others) in the practice of construction (in the broad sense of this concept), which are united by the concept of the Fourth Industrial Revolution. The result of the implementation of these technologies in the construction should be the transition to the widespread use of cyber-physical systems.
The problem of using information technologies in construction today is not due to the lack of this process as such, but to the lack of consistency and consistency in it. Fragmentary nature of the application, inconsistency of the applied technologies at different levels of management and at different stages of the life cycle of construction projects sharply reduce the potential positive effect of informatization and building automation. At the same time, the concept of cyber-physical systems, that is, the integration at the system level of physical processes and controls has proven effective in industrial production.
The approaches to ensuring the processes of designing cyber-physical building systems through the development and application of General mathematical models for the processes of data exchange and management are considered. The presented models of data exchange and management of cyber-physical building systems describe the processes implemented at each stage of the life cycle of cyber-physical building systems. Functional blocks of the considered models allow to describe the processes of data collection, storage and processing on the current and past stages of the life cycle of cyber-physical construction systems. The presented models are the elements of mathematical support of the processes of designing cyber-physical building systems, which determine the processes of information exchange and management between the structures of cyber-physical building systems of different levels of hierarchy in the full life cycle.

The purpose of the article is to review the theoretical foundations and practical examples of investor assessment with an integrated approach to the development of urban infrastructure. The article analyzes the conditions for reducing the investment costs of projects. For this purpose, methods of clarifying the conceptual apparatus, classification, systematization and an integrated approach are used.
The significance of an investment project depends on its positive influence on at least one of the external or internal markets: material and financial products, services and labor, on the social environment and the environment. Examples are provided of the impact on urban planning and the ecology of the urban landscape of investment projects in the field of tourism in recent years, implemented at the expense of the Federal Target Program “Development of domestic and inbound tourism in the Russia for 2011-2018.” in Sarapul, Barnaul and Cherepovets. The authors conclude that in the examples cited there is a relationship between the risk tolerance of the project and the complexity of the approach to its implementation, and as a result, the amount of investment. Large projects are designed not only to solve specific problems of the investor, regions, economy, state and society, but also ensure the profitability of the state budget at various levels, create new jobs, ensure GDP growth in the country and investment in various sectors, create conditions for the development of the country’s regions. The narrowly focused investment projects are fraught with great risks for the investor due to the selectivity and limited scope of the manifestation of effects.

Published: May 2019

Introduction Olfactory groove meningiomas (OGMs) are often associated with loss of smell following resection. Loss of smell has a measurable impact on quality of life. Smell preservation has been previously described in open approaches for early stage or unilateral OGMs. Evidence of smell preservation in endoscopic approaches is lacking.
Design A multi-institutional retrospective review was performed on consecutive patients who underwent unilateral endoscopic endonasal resection of OGM. A gross total resection was achieved with preservation of the contralateral olfactory cleft and bulb. Olfactory function was assessed with a six-point olfactory symptom score and the Sniffin' Sticks 12-item smell identification test (SS-12). Contralateral olfactory bulb volume was measured on postoperative magnetic resonance imaging.
Results Four patients (age 42.0 ± 7.5, 75% female) were assessed. Olfactory function was assessed at 21.8 ± 5.6 months following surgery. All patients reported some degree of smell preservation (75% described a slight/mild impairment in smell or better). Olfactory identification was preserved with an SS-12 score of 9 ± 1.4 (anosmia defined as ≤6). The olfactory bulb volume was calculated to be 47.4 ± 15.9 mm3 (normal >40 mm3).
Conclusion Smell preservation is possible following unilateral endoscopic endonasal resection of carefully selected OGM.
Investigation of L-Carnitine Concentrations in Treated Patients with Maple Syrup Urine Disease

Published: May 2019

AbstractMaple syrup urine disease (MSUD), also known as branched-chain α ketoaciduria, is a metabolic disorder caused by an inborn deficiency in the activity of the branched-chain α-ketoacid dehydrogenase complex. Severe neurological damage occurs in most patients with MSUD although the exact mechanism of neurotoxicity still remains unknown. Studies have suggested that neuropathology in patients with MSUD may be related to oxidative stress. L-carnitine mediates the transport of fatty acids into the mitochondria that are required for β-oxidation and ATP production. Along with the important roles it plays in lipid metabolism, L-carnitine also protects tissues from oxidative damage through its antioxidant properties. The study included a total of 15 patients with MSUD who attended regular follow-up visits, and 15 age-matched healthy control subjects, and aimed to investigate L-carnitine levels in treated patients with MSUD and healthy control subjects. L-carnitine levels were found to be significantly lower in the patient group than in the healthy controls. No significant correlation was identified between the plasma branched-chain amino acids leucine, isoleucine, valine, and L-carnitine levels. Patients with MSUD can be treated with adjuvant therapy with L-carnitine supplementation.

Published: May 2019

AbstractPlexiform neurofibromas are congenital peripheral nerve sheath tumors characteristic of neurofibromatosis type 1 (NF1)—a frequent neurocutaneous disorder caused by mutations of the NF1 tumor suppressor gene. Since plexiform neurofibromas are a major cause of the burden of disease and may also progress to malignancy, many efforts have been undertaken to find a cure for these tumors. However, neither surgery nor medication has so far produced a breakthrough therapeutic success. Recently, a clinical phase I study reported significant shrinkage of plexiform neurofibromas following treatment with the MEK inhibitor selumetinib. Here, we report an 11-year-old NF1 patient with a large plexiform neurofibroma of the neck that had led to a sharp-angled kinking of the cervical spine and subsequent myelopathy. Although surgical stabilization of the cervical vertebral column was urgently recommended, the vertebral column was inaccessible due to extensive tumor growth. In this situation, treatment with the MEK inhibitor trametinib was initiated which resulted in a 22% reduction in tumor volume after 6 months of therapy and finally enabled surgery. These data show that MEK inhibitors may not lead to complete disappearance of NF1-associated plexiform neurofibromas but can be an essential step in a multimodal therapeutic approach for these tumors. The course of our patient suggests that MEK inhibitors are likely to play a significant role in providing a cure for one of the most devastating manifestations of NF1.

Published: May 2019

Objective To investigate differences in oxytocin (OXT) biodistribution between nonobese and obese parturients during labor.
Study Design Patients with body mass index (BMI) of either ≥ 18 ≤ 24.9 kg/m2 (“nonobese”) or ≥ 30 kg/m2 (“obese”) undergoing elective induction of labor were included (N = 25 each). Blood samples were collected at baseline (T0), and 20 minutes after maximal OXT augmentation or adequate uterine contractions (T1) for OXT and oxytocinase assays. A mixed-model repeated-measures analysis of variance was used to test for group versus time interaction and analysis of covariance to detect a difference in OXT level at T1. Data presented as mean ± standard deviation or median (interquartile range), with p < 0.05 considered significant.
Results The mean BMIs (kg/m2) were 22.1 ± 1.6 and 35.9 ± 5.1 in the nonobese and obese groups, respectively. No differences were observed in either the duration of OXT infusion, total dose of OXT, or plasma OXT (pg/mL) either at T0 or T1. However, plasma oxytocinase (ng/mL) was significantly lower at T0 (1.41 [0.67, 3.51] vs. 0.40 [0.29, 1.12]; p = 0.03) in the obese group.
Conclusion We provide preliminary evidence that the disposition of OXT may not be different between obese and nonobese women during labor.

Published: May 2019

Abstract
In the present study, laser micro-milling tests were carried out to fabricate micro-channels on Alumina bio-ceramics (Al2O3), using a Q-Switched 30W Nd:YAG pulsed laser. A systematic approach based on a full factorial Design of Experiment (DoE) has been successfully applied with the aim to detect which and how the key input laser process parameters affect the channel dimensional accuracy. The examined process parameters were the laser beam scanning speed, the pulse frequency and the pulse intensity. Optical microscope was used to analyze the channel geometries responses (i.e. channel's top width, bottom width, depth, and taper wall angle). Moreover, mathematical models for predicting the micro-channel geometries are successfully proposed for controlled micro-milling of micro-channels in Al2O3. Results reveal that, the change of scanning speed and laser intensity significantly affected the ablated channel’s geometries. Further it is observed that the channel depth and width increase linearly with increasing of laser intensity and decreasing of scanning speed and not much affected by changing of pulse frequency. Finally, the experimental results bear a good agreement with the proposed prediction models.

Abstract
All The first results of obtaining radiation-resistant material by the SHS method are presented in the article. Synthesis of material based on the system Fe2O3-Al-Cr2O3-MoO3-Ti. The resulting material was irradiated with an electron beam of 1.8 MeV. The synthesis process was filmed by an action video camera. Fourier image analysis revealed the instability of combustion regimes and predicted the quality of reaction products. A comparative analysis of the microstructure of the samples before and after irradiation with electrons confirmed the results of the FFT. Despite the relatively low quality of the synthesis products, the embrittlement occurred at the absorbed dose of 70 Mrad. In the future, it is planned to improve the methodology for identifying unstable synthesis modes and adjusting the percentage ratio of the charge components.

The modified SOMA stresses the balance between global exploration and local exploitation by introduce adaptive step, and improved the population diversity in the process of individual migration by introduce quadratic interpolation, which effectively avoided the premature and improved the convergence of the SOMA. Finally, through the 4×6 job shop scheduling problem verify the performance of the modified SOMA algorithm, the computational results show that the proposed modified SOMA efficiently solves adaptive job shop scheduling.

Published: May 2019

Abstract
Microbially Induced Calcite Precipitation (MICP) is a technique that utilizes the concept of microbial involvements in calcium carbonate precipitation within the soil matrix structure. This leads to the cementation of the soil particles and consequently improving the strength and stiffness of the soil. In this study microbial carbonate precipitations were induced in tropical residual soil via urea hydrolysis. An isolate of urease active strain of Klebsiella pneumoniae UM123 was used to precipitates calcite into the soil with the aim of improving the engineering properties of the soil. Bacteria concentrations of 2.9 × 106 cfu/ml and 0.5 M cementation reagents concentrations were used to evaluate the strength and hydraulic conductivity of the soil. Treatment durations of 24, 36, 48 and 60 hours were used in the study. The results obtained indicated a general increase in the strength and reduction of hydraulic conductivity of the treated soil with the increase in treatment durations up to 48 hours. It was also revealed that the higher the amount of calcite precipitated the more the strength improvement and reduction of hydraulic conductivity. Appropriate percentage of lime that satisfied the initial consumption and fixation capacity of the soil sample was found to be 6%. Though, combination of MICP with lime does not significantly improve the strength at early stage of the treatment, it has substantially reduced the hydraulic conductivity of the treated residual soil particularly at the early curing period when lime alone increases the hydraulic conductivity.

Published: May 2019

Abstract
The overall aim of this research is to provide an assessment of suction development in a typical soil slope embankment. In particular, it demonstrated how different type of trees via their water-uptake demands enhances the stability of soil slope cutting, within a London clay formation. A total of 7 analyses were performed. The first analysis was performed to determine the saturated undrained Factor of Safety of the un-vegetated case study slope. A mature Oak tree was then superimposed on both the slope toe and its crest, and it was discovered that the presence of the tree at such locations increased the slope Factor of Safety by 2.15% and 2.00% respectively. A mature Horse Chestnut tree was then considered on the slope, and the tree enhanced the slope Factor of Safety by 2.01% and 1.94% on the toe and the crest respectively. The next analysis considered the effect of mature Poplar tree with a root zone deeper than both the Oak and the Chestnut; the Poplar tree increased the slope Factor of Safety by 12.65% and 2.77% at the toe and the crest respectively, indicating tree species with deeper root zone produced greater impacts than those with shallow root zone. Although 2% increase in Factor of Safety is not overlay significant but 12.7% is, therefore the findings indicate the magnitude at which trees with deep root zone enhanced the slope factor of safety albeit more on the slope toe.

Published: May 2019

Abstract
Shear wave velocity (Vs) is considered a key soil parameter in the field of earthquake engineering. The time-averaged shear wave velocity in the upper 30 m (Vs30) layer of soil is used to classify seismic site class. In-situ Vs test is sometimes unsuitable to the project’s need due to financial reasons, noisy environment on site or simply the lack of expertise. This paper attempts to develop a global prediction model for Vs using Standard Penetration Resistance (Nspt), depth (z) and soil type (s

t)
as the independent parameters. Two approaches to modelling would be taken; a multi-linear regression (MLR) model and an ensemble (EN-PSO) model. The EN-PSO model attempts to improve upon the accuracy of the MLR model prediction ability using the ensemble learning method. A dataset was compiled from literatures for this paper. 5 Base models were developed: MLR, Random Forest (RFR), Support Vector Machine (SVR), Artificial Neural Network (ANN) and k-Nearest Neighbor (KNN) which are combined into an ensemble model named EN-PSO. The weights for EN-SPO was then calculated using Particle Swarm Optimization (PSO). The performance of each models were then compared and it was shown that EN-PSO was the best in terms of: MAE (Mean Absolute Error) = 22.085, MAPE (Mean Absolute Percentage Error) = 9.1 %, RMSE (Root Mean Square Error) = 31.741 and R2 Coefficient of Determination) = 0.895. In addition, it was also shown that the EN-PSO model was able to improve upon the performance of the MLR model, which the most accurate among the Base models. Comparisons were also made between EN-PSO and other suggested Universal Vs correlations and EN-PSO was shown to outperform the other correlation based on prediction using a modified Test set. Three new empirical correlations as alternative for the EN-PSO model was also presented.

Published: May 2019

Abstract
Peat is known of its high compressibility, low shear strength, natural moisture content and long-term settlement. This indicates that peat is problematic, and it is necessary to improve the soil so that it can be used for supporting foundations. Fly ash is one of the source materials for geopolymer binders and available abundantly worldwide. It is considered as eco-friendly when it is used in the construction industry since it is a recycled material. A geopolymer mix known as Geopolymer Flexible Activator (GeoFlexA) and fly ash is used as an alternative solution to solve ground settlement issues related to soft soils. The purpose of this research is to modify peat by binding GeoFlexA and fly ash together. This research is carried out to determine the effect of GeoFlexA admixture and fly ash to the strength of peat. The index property tests include moisture content, organic content, fibre content, specific gravity and pH test only. Compaction test and Unconfined Compressive Test (UCT) is used to prepare samples and to analyse the strength respectively. The UCT was conducted after the samples were prepared in the mould and allowed to cure under 0, 7, 14, 28 and 56 days. Various percentages of fly ash used are 5%, 10%, 15% and 20% while a constant GeoFlexA admixture is used at 40% of the soil weight. The experimental results demonstrated that the compressive strength of the modified peat increases significantly with the fly ash content and curing time. These indicated that the mixture of GeoFlexA and fly ash can promote to an enhanced compressive strength of peat, hence, become a potential admixture for modifying peat.

Authors: Mohamad I I , Mohd Yunus M Z , Harith N S H 
Published: May 2019

Abstract
The earthquake may cause many deaths and injuries and extensive property damage and dramatically change the geographic structure of the impacted area. Vulnerability in the context of building structure can be defined as inability to resist the earthquake loadings and unfortunately the majority of existing buildings in Ranau Township were built consequently without seismic consideration. The rapid development had increased the probability of building damages due to the earthquake activities that appeared around the area since. This study aims to identify, evaluate buildings and calculated vulnerability using the Rapid Visual Screening (RVS) method through the framework of Geographic Information System (GIS). The results of this study revealed that from 245 buildings, the damage level for 21 buildings were in grade 3, 11 buildings under grade 2 and other buildings in grade 1 i.e. heavy, moderate and little damages, respectively. After knowing the vulnerability level of buildings, the developer may do an early prevention to avoid further damages due to earthquakes in the future. This method can be used in moderate seismicity region such as Sabah as an early detection for building vulnerabilities.
