The Value Proposition of RFID Technology in Tall Prefabricated Timber Buildings
Authors: Forsythe Perry , Ahmadian Fard Fini Alireza , Jalali Yazdi Alireza
Published: July 2019

The full benefit of prefabricated timber systems in the construction of multi-story buildings depends on integration and efficiency in the upstream logistics and supply chain. The purpose of this research is therefore to determine the potential value that the use of Radio-Frequency Identification technology (RFID) can contribute to the prefabricated construction of timber, and to undertake the basic development of a RFID tracking model for this purpose. The methods used in this study not only build on the knowledge gained from previous literature, but also include interviews with industry experts, field trial design and field trials. The research showed that the RFID tracking system's value proposition tends to be strongest where there are large scale and vertically integrated supply chains, logistics complexity between a limited number of discrete but partnered supply chain links and/or internal logistical complexity problems. Therefore, five distinct added value stages of RFID applications have been found in incoming delivery logistics, factory panel production, outgoing delivery logistics, on-site installation and third parties who can inspect the finished construction work. Application of RFID technology in prefabrication factory environments, where fixed readers can be used in predefined processes, was found promising. However, due to the temporary nature of the sites and the associated investment, the capacity for high automation levels is thought to be more limited on site.
Risks Identification and Allocation in the Supply Chain of Modular Integrated Construction (MiC)
Authors: Y. Wuni Ibrahim , Q.P. Shen Geoffrey
Published: July 2019

Modular integrated construction (MiC) is an offsite construction technique which can improve construction quality, the certainty of the project cost, provide value for money and reduce construction time, waste generation, and carbon emissions. However, MiC is associated with a unique business model, engineering, supply chain, and stakeholder composition, resulting in bespoke uncertainties and risks. Prominent among them is the uncertainties and risk events in its linked supply chain segments. However, risks identification and allocation in the MiC supply chain segments is not well-established. This research identified and assessed 28 risk events (REs) across the manufacturing, logistics and on-site assembly segments of the MiC supply chain. A principal component analysis generated 10, 6 and 12 REs within the modular manufacturing, logistics, and on-site assembly segments, respectively. A fuzzy synthetic evaluation (FSE) modeling revealed that the on-site assembly REs are the most critical set of risk events with a criticality index of 5.58, followed by the modular manufacturing risk events (5.28) and logistics risk events (5.08). These rankings and criticality assessment have profound implications for the practice and praxis MiC risks management. It is a source of relevant information to stakeholders and practitioners in understanding the MiC supply chain risk events and may prioritize the riskiest events to improve the performance of MiC projects. Again, the assessed REs contributes to the checklists of MiC risk events and may form the basis for future studies on the risk of MiC. Future studies may examine the assessed risk events in different countries using larger samples.
A Pilot Study of Identifying Execution Plan Differences for Accelerated Bridge Construction
Authors: Prajapati Elina , Ouk Choi Jin
Published: July 2019

Accelerated bridge construction (ABC) is an innovative construction technique used to accelerate the construction of new bridges, as well as the renovation/replacement of existing bridges. Due to the benefits offered by ABC, transportation authorities have a higher preference in executing an accelerated approach over conventional bridge construction. The execution of an accelerated approach has differences when compared to the conventional approach, and it is important to identify such differences for the successful implementation of ABC projects. However, there have been no studies to identify such execution differences. Therefore, this study was conducted to identify execution plan differences relevant to ABC. For this purpose, an extensive literature review was conducted to prepare a preliminary list of execution plan differences. Then, a questionnaire survey was administered with the industry experts, who were previously involved in the execution of ABC projects, to validate the preliminary list. Based on the literature review and the responses from questionnaire survey, this study identified 61 execution plan differences relevant to ABC in different phases of execution. This study is expected to benefit owners, contractors, and road/bridge users for successful execution of ABC projects.
Serviceability Performance of Timber Concrete Composite Floors
Authors: Tannert Thomas , Ebadi Md Mehdi , Gerber Adam
Published: July 2019

There is much potential for engineered wood products to be used beyond low-rise residential construction when incorporating the notion of hybrid systems like timber-concrete-composites (TCC). TCC systems are comprised of a timber element connected to a concrete slab through a shear connection. By combining the complimentary properties of timber and concrete, the performance of timber floors can be enhanced, including bending stiffness, load-bearing capacity, dynamic response, airborne sound transmission, structural fire rating, and thermal mass. A large number of T-beam TCC systems existed for decades; however, the growing availability of panel-type products in North America offers designers greater versatility in terms of structural and building physics performance. While stiffness and strength design of TCC systems is straight-forward, there is little design guidance available in terms of vibration and long-term performance. The bending, vibration and long-term performance for a range of TCC systems in several EWPs were validated on small-scale shear tests, floor panels subjected to serviceability loads for 2.5 years, and subsequent full-size bending tests. The tests confirmed that calculations according to the ?-method can predict the basic stiffness and dynamic properties of TCC floors within a reasonable degree of accuracy.
Mass Timber Modular Construction: Developments in Oregon
Authors: Sheine Judith , Donofrio Mark , Gershfeld Mikhail
Published: July 2019

With the mass timber industry taking off in 2015 in Oregon, when DR Johnson Lumber in Riddle, OR started producing CLT panels, government officials were eager to support it for its promise of economic development in rural communities and also had hopes of addressing the state’s affordable housing crisis using mass timber modular construction. While mass timber modular housing has had some success in Europe, the different construction standards and building culture in the United States make it more challenging. With few areas in Oregon in which housing is likely to be built over six stories tall or in large-scale developments, it did not seem possible that mass timber could solve the affordable housing crisis where it cannot compete in cost with standard light wood-frame construction. However, it did seem feasible that mass timber panels, which are so well-suited to customizable pre-fabrication through digital manufacturing, might be successful in an alternative building type for modular construction: classrooms. In successful models of mass timber modular classrooms in Austria and Germany, schools were built in much shorter timeframes and for 25% less cost than steel or concrete construction. The authors are now working with a modular building manufacturer in Oregon, Modern Building Systems (MBS), that produces custom-designed modular light wood-frame classrooms. While mass timber classrooms cannot compete in price with light wood-frame, particularly in single-story applications, they could be competitive for two story (or taller) schools, which are usually built using steel braced-frame and concrete block. Because MBS is 18 miles west of Freres Lumber, which is newly producing Mass Plywood Panels (MPP), and the MBS facility needs no modifications to use MPP instead of wood-frame, the authors are working with them to design an economically competitive mass timber module, with several potential clients interested in testing a prototype in 2019.
Spectral conditions of existence of the graph circumference
Authors: Benediktovich V. I.
Published: July 2019

A graph parameter – a circumference of a graph – and its relationship with the algebraic parameters of a graph – eigenvalues of the adjacency matrix and the unsigned Laplace matrix of a graph – are considered in this article. Earlier we have obtained the lower estimates of the spectral radius of an arbitrary graph and a bipartitebalanced graph for existence of the Hamiltonian cycle in it. Recently the problem of existence of a cycle of length n – 1 in a graph depending on the values of its above-mentioned spectral radii has been investigated. This article studies the problem of existence of a cycle of length n – 2 in a graph depending on the lower estimates of the values of its spectral radius and the spectral radius of its unsigned Laplacian and the spectral conditions of existence of the circumference of a graph (2-connected graph) are obtained.
Necessary condition for solvability of the control problem of an asynchronous spectrum of linear almost periodic systems with trivial averaging of the coefficient matrix
Authors: Demenchuk A. K.
Published: July 2019

We consider a linear control system with an almost periodic matrix of coefficients. The control has a form of feedback and is linear in phase variables. It is assumed that the feedback coefficient is almost periodic and its frequency modulus, i.e. the smallest additive group of real numbers, including all Fourier exponents of this coefficient, is contained in the frequency module of the coefficient matrix.

The following problem is formulated: choose such a control from an admissible set so that the closed system has almost periodic solutions, the frequency spectrum (a set of Fourier exponents) of which contains a predetermined subset, and the intersection of the solution frequency modules and the coefficient matrix is trivial. The problem is called the control problem of the spectrum of irregular oscillations (asynchronous spectrum) with a target set of frequencies.

The aim of the work aws to obtain a necessary solvability condition for the control problem of the asynchronous spectrum of linear almost periodic systems with trivial averaging of coefficient matrix The estimate of the power of the asynchronous spectrum was found in the case of trivial averaging of the coefficient matrix.
Construction of the Fuchs equation with four given finite critical points and a given reducible monodromy group in the resonance case
Authors: Amel’kin V. V. , Vasilevich M. N.
Published: July 2019

One inverse problem of the analytic theory of linear differential equations is considered. Namely, the completely integrable Fuchs equation with four given finite critical points and a given reducible monodromy group of rank 2 on the complex projective line is constructed. Reducibility of the monodromy group of rank 2 means that 2×2-monodromy matrices (the generators of the monodromy group) can be simultaneously reduced by a linear nonsingular transformation to an upper triangular form. In so doing we study the case when the eigenvalue ξj of the diagonal matrix of the monodromy formal exponent at a corresponding Fuchs critical point is equal to an integer different from zero (resonance takes place).

Published: July 2019

For fullerene matrixes doped by gold nanoparticles we have established experimentally a miss of a red concentration-induced shift of surface plasmon resonance absorption band maximum. Theoretical modeling has been made for spectral characteristics of carbon–bearing nanostructures. Numerical calculations of extinction factors for a spherical metallic particle in an absorbing surrounding medium were based on the Mie theory. Transmission spectra coefficients of densely packed plasmonic nanoparticles monolayers were calculated with the use of the single coherent scattering approximation modified for absorbing matrices. Thin-film Au-air and Au–C60 nanostructures have been fabricated on glass and quartz substrates by thermal evaporation and condensation in vacuum at an air pressure of 2 · 10–3 Pа. The surface mass density of Au into Au–C60 nanostructures was varied in the range (3.86–7.98) · 10–6 g/cm2. The comparison of theoretical and experimental data allowed making a conclusion that the absorbency in carbon-bearing matrix leads to the attenuation of lateral electrodynamics coupling and blocks collective plasmon resonance in densely packed gold nanostructures.

Published: July 2019

In this article it is shown that by performing Levi–Chivita-type transformations in the two-dimensional Helmholtz and Klein–Fock-type equations, it is possible to determine coherent states in a standard way. Moreover, if in the case of the Helmholtz elliptic equation the Levi–Civita transformation is realized by a complex quadratic map, then in the case of the Klein–Foсk-type equation it is realized by an analogue of such a map however defined for functions of a double variable. The coordinate and momentum representations of the coherent state are found. The purpose of constructing coherent states in the described manner is a further development of the hadron model proposed in [1; 2].

Authors: Savchenko G. E. , Bachyshcha T. S. , Kabashnikova L. F.
Published: July 2019

Еffects of β-1,3-glucan from euglena (Euglena gracilis) were studied in vivo by evaluating pH changes outside and inside the cell in the tissues of the 7-day leaves of barley seedlings with the use of pH-sensitive probes of FITC-dextran and pyranine. It was found that the incubation of barley leaves separated from the roots in the solution of β-1,3-glucan (0.01 %) for 40 min did not cause acidification of cytoplasm as a typical nonspecific plant response to wound stress. The inoculation of intact seedlings with Bipolaris sorokiniana (Sacc.) Shoem. spores resulted in alkalization of apoplast by 1.7 pH units, and pretreatment of seedlings with β-1,3-glucan a day before the fungal infection promoted its acidification (1.04 pH units) compared to the infected variant, indicating an increased performance of ATPase, which pumped protons from cytoplasm into apoplast. The conducted studies contribute to the selection of optimal concentrations of β-1,3-glucan for immunomodulatory mixtures.

The results on the effect of introduction of iron aluminide of various chemical and phase compositions on the structure and mechanical properties of powdered carbon steel and tin bronze are presented. It is shown that the introduction of 0.5 % single-phase iron aluminide Fe3Al leads to an increase in the strength of powdered carbon steel by 30–40 MPa, of biphase Fe2Al5 –FeAl3 – by 80–90 MPa, 1 % – to an insignificant decrease in strength. When a single-phase iron aluminide in the powder steel structure is introduced, a decrease in cementite, differentiation is observed, aluminum diffusion into the substrate occurs, and when two-phase aluminide is introduced, the structure griding occurs as well. It is established that the introduction of 0.5 % single-phase iron aluminide into powder bronzes makes it possible to increase its strength by 80– 100 MPa, two-phase – leads to a reduction in strength by 40–50 MPa. Introduction of 1 % single-phase iron aluminide and 0.2–1 % biphasic aluminide causes a change in the morphology of the structure of the powder bronze due to alloying the copper with aluminum and iron.

Published: July 2019

Composites based on calcium phosphates in the matrix of biopolymer (citrated plasma and fibrin) were synthesized in neutral and alkaline medium. At pH 7 brushite composites were obtained, whereas at pH 11 amorphized hydroxyapatite was precipitated. Disruption of precipitation conditions led to the formation of tricalcium phosphate impurity, which was detected by XRD after thermal treatment of composites at 800 °C. Composition and morphology of calcium phosphates did not depend on biopolymer nature. To determine bioactivity degree, composites were incubated in model Simulated Body Fluid (SBF) for 75 days. It was found that composites based on amorphized hydroxyapatite incorporated in biopolymer matrix have maximum growth of biomimetic layer of apatite.

Published: July 2019

A convenient three-step method for synthesis of heptyl (4-triﬂuoroacetyl)benzoate, an important neutral anion carrier, has been developed. The key step of the method is acylation of toluene by triﬂuoroacetic anhydride in presence of aluminium chloride at –8 – –10oC. The procedure gives high overall yield and, unlike the earlier methods, does not include any organometallic reagents, therefore allowing scaling it up to several hundred grams, that makes the target compound much more readily available.

Authors: Sosnovskaya A. A. , Fleisher V. L. , Borkina Y. V.
Published: July 2019

Optimization of the liquid-phase oxidation of α-pinene was carried out using the Box plan. It was found that an increase in the temperature of the oxidation process in the interval 55–85 °C leads to an increase in the amount of polymers from 45 to 55 %, and a decrease in the air ﬂow rate from 1000 to 600 ml/min – to a 10 % decrease in terpenic oxygencontaining compounds (verbenol, verbenon, epoxy α-pinene). Increasing the duration of oxidation from 5 to 15 h leads to a reduction in the content of α-pinene from 70 to 48 %, which indicates its high conversion. The results of the experimental plan have been processed, the optimum process conditions found, which ensure the maximum yield terpenic oxygencontaining compounds and a high conversion α-pinene with the minimum content of polymers in the oxidation products, have been calculated and confirmed in practice. It was established that at a temperature of 70–75 °C, an air ﬂow rate of 1000 ml/min and an oxidation time of 5 h, the quantitative content of the main products was: terpenic oxygen-containing compounds – 27.04 %, monomers – 69.70 %, polymers – 30.30 %.

Published: July 2019

The article describes a possible way of introducing nanoscale powders into energy-saturated heterogeneous composite materials (ECM). By the example of polydispersed nanoscale carbon, the main well-known methods for introducing nanoscale components into dispersed and high-viscosity colloidal systems have been studied, their effectiveness has been evaluated, and limitations have been revealed. The main influencing factors on the uniform distribution of nanoscale components in the volume of the composite material and the ways of leveling their influence have beenfound. A technological scheme has been proposed for increasing the distribution uniformity of nanoscale components due to their preliminary deposition on the surface of the material prevailing in quantity of dispersed component while limiting the growth of its specific surface as a method of further reduction of the viscosity of the energy-saturated heterogeneous composite material at the stage of mixing its liquid and solid phases.

The rate of change of the form factor, specific surface and distribution of the nanoscale diamond-containing additive over the particle surface of ammonium salt of perchloric acid has been studied depending on the modes of mixing the components in a gravity mixer. Acceptable technological mixing modes have been found.

The main tasks of further study of phenomena arising at the phase boundary when introducing nanoscale additives into the dispersed medium of ECM have been determined.

Published: July 2019

Anodizing of aluminum and its alloys is widely used in various fields of science and technology. The process of modifying porous anodic aluminum oxide with ultradispersed diamond (UDD) particles to improve the mechanical characteristics of coatings requires additional study. UDD was modified by consistent heat treatment at 40 °C and 120 °C. The results of the UDD surface modification were controlled by IR spectroscopy. The surface state analysis was carried out using the PMT-3 microhardnessmeter, the SolverPro P47 atomic-force microscope (AFM), and the experimental probe-electrometry device. One of the ways to improve the mechanical characteristics of such coatings is the use of ultradispersed diamonds with respective pretreatment of their surface. The article presents the results of a study of the influence of additives of ultradispersed diamonds with different functional surface composition in an acid electrolyte to form coatings of porous anodic alumina on the surface of AMg-2 aluminum alloy substrates by electrochemical oxidation. An increase in the microhardness and wear resistance of anodic oxide coatings formed on aluminum alloy substrates after various post-growth heat treatments is noted. It is shown that using a combined method based on doping anodic alumina in the process of synthesis with modified ultradispersed diamonds and post-growth annealing of the coatings obtained in vacuum at T = 500 °C, it is possible to obtain a composite material that is 2 times higher in hardness and 3 times higher in wear resistance compared to the initial coating. The research results can be used to create a new generation of radiation-resistant heat-removing bases, nano and micromechanical devices, elements of passive and active electronics, high-quality parts for spacecraft and satellites on modern composite materials.

Furthermore, from the calculation of animal satisfaction and visitor satisfaction obtained 62% of visitor satisfaction and obtained 92% of visitor disappointment. The greatest satisfaction is obtained from the 25th attribute, namely officers who provide services neatly, politely and friendly. While the attribute with the lowest customer satisfaction value is the 17th attribute included in the must-be category, namely the suitability of available collections and available information. Indicates attributes that have little importance to customer satisfaction. Furthermore, for the disappointment visitors get the 25th attribute, which is to deny not providing services neatly, politely and friendly. And for the high level of disappointment is the 1st attribute classified as indifferent, namely the location of the strategic library layout.PT. Latif merupakan industri yang bergerak dalam bidang furniture rotan sintetis, yang salah satu produk terlaris adalah SH-15. Masalah dalam penelitian ini mengenai persediaan bahan baku dengan menggunakan sistem made in order. Oleh karena itu dibutuhkan suatu sistem informasi yang diharapkan dalam pemenuhan kebutuhan bahan baku dapat dilakukan dengan tepat dan penentuan biaya persediaannya dapat ditetapkan seoptimal mungkin yaitu melalui penerapan MRP. Variabel penelitian dalam hal ini adalah perencanaan persediaan bahan baku. MRP diawali dengan melakukan peramalan akan jumlah permintaan/ produksi untuk waktu yang akan datang. Peramalan ini dilakukan dengan menggunakan metode Moving Average N = 1, dan Single Exponential Smoothing ï¡ = 0.8. Lalu ditentukan nilai terkecil dari SEE, MAD, dan MAPE dari masing-masing metode. Setelah terpilih salah satu metode terbaik maka metode tersebut akan dijadikan landasan untuk meramalkan jumlah kebutuhan permintaan selama satu tahun kedepan. Perbandingan antara biaya persediaan minimum metode Lot for Lot sebesar Rp.60.000 dan Part periode Balancing sebesar Rp. 44.733.750,-. Dari hasil penghitungan kedua lot sizing dapat diambil kesimpulan bahwa penerapan metode Lot Sizing Lot for Lot untuk setiap bahan baku SH-15 pada PT. Latif dapat meminimalkan biaya total persediaan sebesar Rp 60.000,- apabila dibandingkan dengan metode Lot Sizing Part Period Balancing.Â Â

PT XYZ is one of the company that move in telecommunications services, starter pack products, and vouchers. The problems in PT XYZ is lateness of starter pack activation in regional warehouse that cause waiting time of starter packâ€™s pick up by retailer. Lateness problem happened because there is no fixed scheduling policy yet, so there is no determination of jobâ€™s priority. In this research will be developed scheduling policies including job allocation each machine per day and sequencing of job. The method used is the earliest due date. In this method, job sequence will be determined based on the smallest due that influence the Completion time of a job. Scheduling do for one machine that doing six jobs in one week. The data used is the starter pack activation data in October 2014. Based on the existing calculations condition, there is a delay of 7.8 hours on job Site Â s in Jakarta and 15.3 hours on job Site Â s Surabaya. Processing time and due date of each job are the input in the methods used. The results of calculation of the proposed conditions in PT XYZ by using a method capable of lowering the earliest due date delay activation up to 38% compared to the existing condition. Completion time of 6 job in a week with the existing condition is 30.3 hours to 18.3 hours on the proposed conditions.PT XYZ merupakan salah satu perusahaan yang bergerak di bidang jasa telekomunikasi, produk starter pack, dan voucher pulsa. Permasalahan yang terjadi pada PT XYZ yaitu keterlambatan aktivasi starter pack digudang regional yang menyebabkan terjadinya waktu tunggu pengambilan starter pack oleh retailer. Permasalahan keterlambatan terjadi karena belum adanya kebijakan penjadwalan pasti, sehingga belum adanya penentuan prioritas job. Pada penelitian ini, akan dikembangkan kebijakan penjadwalan termasuk pembagian job setiap mesin per hari dan pengurutan pengerjaan job. Metode yang digunakan adalah earliest due date. Pada metode ini akan ditentukan urutan pengerjaan job berdasarkan due date terkecil yang berpengaruh terhadap waktu penyelesaian suatu job. Penjadwalan dilakukan terhadap satu mesin yang mengerjakan enam job dalam satu minggu. Data yang digunakan adalah data aktivasi starter pack periode Oktober 2014. Berdasarkan perhitungan kondisi eksisting, terdapat keterlambatan 7.8 jam pada job site Jakarta dan 15.3 jam pada job site Surabaya.

In this research, biodiesel was produced from new feedstock Kemiri Sunan oil. Kemiri Sunan oil is non edible oil, an attractive raw material for production of biodiesel. Biodiesel was produced by two steps of reactions, i.e. esterification and transesterification, using H2SO4 and KOH as catalyst, respectively. Esterification reaction was carried out with methanol for 2 h, ratio oil:methanol (3:1). Transesterification was done at various catalyst concentration (0.5; 1.0; 1.5; 2.0 %wt oil), ratio oli:methanol (1:1, 2:1, 3:1 (wt/wt)), and reaction temperature (30, 50, 65, 70oC) for 1 h. The yield and properties of biodiesel were analysed by Gas Chromatography (GC) and ASTM D 6751 methods, respectively. High yield of biodiesel was produced at KOH 1 %wt catalyst, ratio methanol:oil (1:1) and 65oC i.e. 96,91 %. Kemiri Sunan oil-based biodiesel had a range of acid number 0,41-0,56 (mgKOH/g), densitas 0,89-0,91 (g/cm3), viscosity 8,28-12,70 (cSt), cetane number 58,2-63,3, and residu carbon 0,23-0,59.\Â Pada penelitian ini, biodiesel diproduksi dari new feedstock minyak Kemiri Sunan. Minyak Kemiri Sunan merupakan minyak non edible sehingga sangat menarik untuk diproduksi sebagai biodiesel. Minyak Kemiri sunan diproduksi dengan dua tahapan reaksi yaitu reaksi esterifikasi dan transesterifikasi menggunakan katalis H2SO4 dan KOH. Reaksi esterifikasi telah dilakukan perbandingan minyak:metanol (3:1) selama 2 jam. Reaksi transesterifikasi dilakukan dengan variasi konsentrasi katalis KOH (0,5; 1,0; 1,5; 2,0 %berat minyak), rasio minyak:metanol (1:1; 2:1; 3:1 (berat/berat)), dan suhu reaksi 65 selama 1 jam. Yield dan sifat biodiesel dianalisis dengan Chromatography Gas (GC) dan ASTM D 6751. Yield optimum biodiesel diperoleh sebesar 96,91%, pada kondisi optimum konsentrasi katalis KOH 1 % berat minyak, rasio minyak:metanol 1:1 (berat/berat) dan suhu reaksi 65oC.
