A study of the daily life of modern teenagers: the presence in social networks as an integral component of communication
Authors: Koroleva D.O.
Published: September 2016

The article introduces the methodologies of the study of the everyday life of modern teenagers whiсh can simultaneously be used to traceevents occurring in real and virtual space: “Online and offline diary" and "15 minutes". The data of pilot studies showed that the teenager’s online performance is mainly presented in a form of communication in social networks. We have discovered that the on- and offline convergence of space for growth is inseparable from respondents themselves. Through the active use of social networks, a modern teenager is able to be present in different socialenvironments simultaneously. Constant checking news and posts in social networks is a new, peculiar to teenage daily ritual. The so-called "red zones", where a teenager consciously waives the possibility of "escape" into a parallel reality, are linked to significant events in everyday life, while a feeling of boredom brings to life the compensation through "getting about" in virtual space

Authors: Litvinova E.Y. , Kiseleva N.V.
Published: September 2016

The article represents the analysis of the existing definitions of the phenomenon of students’ involvement, its multidimensional nature and the lack of common under- standing of its structure. Some actual models of involvement in education, suggested by domestic and foreign researchers, are analyzed, and the importance of studying the characteristics of involvement in continuing education is emphasized and lack of such research is revealed. The necessity of study the phenomenon of involvement in continuing education as a multidimensional construct is proved by arguments. The authors suggest and ground their five-component model of students’ involvement in continuing education, including cognitive, affective, behavioral , motivational and axiological components.

Authors: Koltachuk E.V. , Vachkov I.
Published: September 2016

The article represents socio-psychological analysis of gender-specific experiences of uncertainty of professional status in the period of maturity. The authors describe the results of qualitative and quantitative data analysis of 112 people aged 33—39 years old, employed on full time and staying in a situation of threat of job loss or change of important parameters of their employment. On the basis of obtained results the authors make the conclusion about the existence of gender differences in the experiences of uncertainty of professional status in the period of maturity, which become apparent in the decreasing trends of the individual components of the experience of uncertainty from sample to sample, in the differences in the level of expression of these components, as well as in the differences in the configuration of the correlation relationship with different types of gender identity at this stage of ontogenesis. The article indicates the ordered impact of gender identity on the experience of professional status uncertainty in adult life, which is evident in a non-random trend of decreasing symptoms from sample to sample: passion, integral readiness for change and distraction decrease from masculine to feminine; from feminine to masculine — emotions and MITN decrease; from androgynous to feminine — avoidance decreases; from masculine to androgynous — frequency of problem-focused coping decreases.

We propose a new approach to classifying diagnostic crystallographic images. The classification procedure uses a three-nearest neighbor algorithm based on the Euclidean distance. The image segmentation is conducted in a spatial domain, with energy values in each segment serving as features. Based on the value of the separability criterion used in discriminant analysis, most informative features and their respective segments are selected. With the classification using only informative segments, the classification error is shown to be reduced by 2% when compared with the use of the entire image.

Published: September 2016

Duplicates embedding is one of the most frequently used type of digital image change. The copy-move procedure includes copying an image fragment from one part and pasting it to another part of the same image. Moreover, this fragment can be changed using some transformations, like affine or contrast enhancement. Existing copy-move detection methods consist of two main steps: feature calculation in overlapping processing windows and the nearest feature search in Euclidean space using lexicographic sorting or kd-tree search. In this paper we suggest to use binary space partitioning trees on the second step of the detection algorithm – vp-tree (vantage-point tree). We present the search speed comparison using vp-tree and kd-tree. The results show advantage of the proposed solution over kd-tree use.

The article describes parallel implementations of two parametric identification algorithms. The first algorithm is based on the estimation of Bravais unit cell parameters, and the second one estimates Wigner-Seitz cell volumes. The developed parallel implementations are based on the two-tier model of concurrency. An external tier of concurrency uses Message Passing Interface (MPI) technique to distribute parametric identification tasks between computing nodes. An internal tier uses Open Multi-Processing (OpenMP) technique to split single steps of the parametric identification algorithms into independent subtasks. Experimental results on multi-processor / multi-core systems have demonstrated almost linear speedup of the parallel implementations, confirmed the effectiveness of the two-tier concurrency model and proved the stability of the identification approach under lattice distortion.

Determination of spectrums of samples responses on external vibroexcitation via pulse-periodic laser action by CO2 laser ROFIN DC 010 and registration of their wave forms have been performed. While analysing the samples’ responses using pulse-periodical laser action, it has been found that vibration rate increases in the case of frequencies, which are divisible by the frequency of initial oscillation, during the amplitude decrease and the frequency increase. The dependence of heat rate on the nanoporous structure formation in the absence of the metallic material melting has been researched. While heating the sample, its temperature was highest at its centre. An increase of the laser action time led to a rise in the temperature of the sample’s centre, causing the rate of pore formation has increased. Since the diffusion coefficient is related to the temperature through an exponential law, the temperature rise is an effective way to increase rate of the process. However, non-permanent elastic deformation, which is caused by high-powered external action, is a necessary condition for developing a generic thermodynamic moving force, which increases the rate of nanoporous structure formation in metallic material.

Design and Development of Gas Sensor Based On Acoustic Resonance
Authors: Febrina Melany
Published: September 2016

Determination of the specific toxic, harmful, or flammable gases concentration i.e. butane, cannot be done directly. It requires devices that can do this measurement without any direct contact between the gas and human (observer) i.e. gas sensors. These sensors are typically used in security systems or early warning system. This research is about design and development of a gas sensor based on acoustic resonance. The sensor that has been developed is acoustic resonator based sensor, with two speakers as the sources of acoustic vibrations. This sensor is made to work at its resonance frequency. Since the resonance frequency of acoustic resonator is influenced by the speed of sound in the acoustic resonator, and the speed of sound is influenced by the density and concentration of the gas in the acoustic resonator, the changing of gas concentrations will cause resonance frequency shifting of the acoustic resonator. So, by taking measurement of resonance frequency shifting of resonator, gas concentration can be determined. This research was conducted in four stages, the first stage is designing of acoustic resonator, the second stage is manufacturing and initial testing of the acoustic resonator, the third stage is conditioning stage to make acoustic resonator works at its resonance frequency automatically, and the final stage is the testing stage of acoustic resonator using butane. Based on the research conducted, it can be concluded that the acoustic resonator system can work accurately and precision to detect the changing of butane gas concentration. Absolute error and relative error are relatively small, the largest of absolute error is 7.69% and the largest relative error is 0.47%.

The WiMax (Worldwide Interoperability for Microwave Access) is a technology in broadband wireless access, which employs OFDM (Orthogonal Frequency Division Multiplexing) as an alternative transmission to enable high speed data in communication system. This research aim is to analyze the performance system of the OFDM-Based WiMAX, which used the cyclic prefix. The model was designed in four schemes of simulation method, the BPSK (Binary Phase Shift Keying, QPSK (Quadrature Phase Shift Keying), 16 QAM (Quadrature Amplitude Modulation) and 64 QAM. Each scheme was investigated BER (Bit Error Rate) on AWGN (Additive White Gaussian Noise) channel and multipath Rayleigh fading channel, which had applied the cyclic prefix. By simulation of the cyclic prefix was produced the modulation measurement of the BPSK, QPSK, 16 and 64 QAM. The performance result of Eb/No 15 dB was obtained the BER of BPSK and QPSK of 1.11E-11, the BER of 16 QAM and 64 QAM of 8.69E-06 and 0.00333 respectively. Those results indicated much smaller BER value than EbNo 0 dB which BPSK and QPSK of 1 BER, 1.5 and 1.75 BER for 16 QAM and 64 QAM respectively. In conclusion, a higher value of EbNo, hence the BER value would be lower.

The commercial MCMB, which was fabricated by LinyiTM, was sintered at 500⁰C for five hour to make graphitized MCMB.  The microstructure of graphitized MCMB was characterized using XRD and SEM to show the crystalinity, crystal phase and morphology of the MCMB particle. The result indicated that the crystal phase of the sample was changed into graphitized carbon .The electrode was made using coating method. We used copper foil as the substrate for anode. The anode materials consist of graphitized MCMB (active material), Polyvinylidene fluoride/PVDF (binder) and acetylene black (additive material). Full cell battery was tested using charge-discharge and cyclic voltammetry (CV) methods. From the CV characterization, cyclic voltammograms of the cell show characteristic lithium intercalation through reduction-oxidation peak. Charge-discharge test showed the discharge and charge capacity of the cells. According charge discharge test, commercial MCMB was better that graphitized MCMB.

Preparation of hierarchical macropore activated carbon monolith (HMACM) from rubber wood was investigated. The samples were prepared with small cutting of rubber wood in cross sectional method. The electrode preparation was started by pre-carbonization process followed by carbonization at 600 oC and physical activation process at 900 oC in N2 and CO2 gas atmosphere, respectively. The samples then were followed by chemical activation process with combination of chemical activation agent of KOH and HNO3 solutions. The HMACMs were neutralized by immersing the samples in copious amount of water and dried the samples for 24 hours. Porosity properties were performed by N2 adsorption-desorption data and morphology characterization was analyzed by scanning electron microscope (SEM) instrument. The electrochemical properties was studied by electrochemical impedance spectroscopy, cyclic voltammetry and charge-discharge at constan current methode.  The SEM micrograph and adsorption-desorption data were also proved that the HMACM sample have a hierarchical macropore at the surface and crossectional section. The porosity data shown the HMACM sample have BET surface area of 331 m2/g with average pore diameter of 1.7 nm. Equivalent series resistance and optimum capacitance specific of the HMACM electrode of 0.77 Ohm and 154 F/g, respectively. In conclusion, this study showed that the preparation method would propose as a simple method of HMACM electrode preparation technique for supercapacitor applications.
Value Chain Analysis of Palm Oil Biodiesel through a Hybrid (ISO-Eco) Life Cycle Assessment Approach
Authors: Manik Yosef
Published: September 2016

This study assesses the life-cycle impacts of palm oil biodiesel value chain in order to provide insights toward holistic sustainability awareness on the current development of bio-based energy policy. The assessment methodology was performed under a hybrid approach combining ISO-14040 Life Cycle Assessment (ISO-LCA) technique and Ecologically-based Life Cycle Assessment (Eco-LCA) methodology. The scope of this study covers all stages in palm oil biodiesel value chain or is often referred to as “cradle-to-grave” analysis. The functional unit to which all inputs and outputs were calculated is the production of 1 ton of biodiesel. For the analysis, life cycle inventory data were collected from professional databases and from scholarly articles addressing global palm oil supply chains. The inventory analysis yields a linked flow associating the land used, fresh fruit bunch (FFB), crude palm oil (CPO), per functional unit of 1 kg of palm oil biodiesel (POB). The linked flow obtained in the inventory analysis were then normalized and characterized following the characterization model formulated inISO-LCA guidelines. The aggregation of ecological inputs was classified based on the mass and energy associated to each unit process in the value chain, which are cultivation, extraction, conversion, and utilization. It is noted that compared to other unit processes, cultivation is the most crucial unit process within the whole palm oil biodiesel value chain. This study serves as a big picture about the current state of palm oil biodiesel value chain, which will be beneficial for further improving oversight of the policy making and service toward sustainable development.

 
Binary Composite Fiber Elasticity using Spring-Mass and Non-Interacting Parallel Sub-Fiber Model
Authors: Viridi Sparisoma
Published: September 2016

Composite materials have been investigated elsewhere. Most of the studies are based on experimental results. This paper reports a numerical study of elasticity modulus of binary fiber composite materials. In this study, we use binary fiber composite materials model which consists of materials of types A and B. The composite is simplified into compound of non-interacting parallel sub-fibers. Each sub-fiber is modeled as Ns point of masses in series configuration. Two adjacent point of mass is connected with spring constant k (related and proportional to Young modulus E), where it could be kAA, kAB, or kBB depend on material type of the two point of masses. Three possible combinations of spring constant are investigated: (a) [kAB < min(kAA, kBB)], (b) [min(kAA, kBB) < kAB < max(kAA, kBB)], and (c) [max(kAA, kBB) < kAB]. The combinations are labeled as composite type I, II, and III, respectively. It is observed that only type II fits most the region limited by Voight and Reuss formulas.
Predicting the Motion of an Intruder in a Vertically Vibrated 2D-Granular-Bed using Contact Points Approximation
Authors: Khotimah Siti Nurul
Published: September 2016

In this study, 2-dimensional Brazil nut effect experiments were setup. An intruder moves from its initial position at the middle-bottom of a container to its final position at the top of the granular bed. To predict the motion of the intruder, the number of contact points for each grain around the intruder was counted manually for grains in the first layer until the third layer. The average numbers of contact points from grains in each of 8 directions respected to the center of the intruder were calculated to determine the direction of total force acting on the intruder by grains in the first layer, in the first two-layers, and in the first three-layers.The result will be more acceptable using the data of two or three layers of grains in predicting intruder movement.

Authors: Suryanita Reni
Published: September 2016

Artificial Neural Network (ANN) method is a prediction tool which is widely used in various fields of application. This study utilizes ANN to predict structural response (story drift) of multi-story reinforced concrete building under earthquake load in the region of Sumatera Island. Modal response spectrum analysis is performed to simulate earthquake loading and produce structural response data for further use in the ANN. The ANN architecture comprises of 3 layers: an input layer, a hidden layer, and an output layer. Earthquake load parameters from 11 locations in Sumatra Island, soil condition, and building geometry are selected as input parameters, whereas story drift is selected as output parameter for the ANN. As many as 1080 data sets are used to train the ANN and 405 data sets for testing. The trained ANN is capable of predicting story drift under earthquake loading at 95% rate of prediction and the calculated Mean-Squared Errors (MSE) as low as 1.6.10-4. The high accuracy of story drift prediction is more than 90% can greatly assist the engineer to identify the building condition rapidly due to earthquake loads and plan the building maintenance routinely.
Effect Of U-9mo/Al Fuel Densities On Neutronic And Steady State Thermal Hydraulic Parameters Of Mtr Type Research Reactor
Authors: PINEM Surian
Published: September 2016

The objectives of this research work are to carry out a detailed neutronic and steady state thermal hydraulics analysis for a MTR research reactor fuelled with the low enrichment U-9Mo/Al dispersion fuels of various uranium densities. The high density uranium fuel will increase the cycle length of the reactor operation and the heat flux in the reactor core. The increasing heat flux at the fuel will causing increase the temperature of the fuel and cladding so that the coolant velocity has to be increased. However, the coolant velocity in the fuel element has a limit value due to the thermal hydraulic stability considerations in the core.  Therefore, the neutronic and the steady state thermal hydraulic analysis are important in the design and operation of nuclear reactor safety.  The calculations were performed using WIMS-D5 and MTRDYN codes. The WIMS-D5 code used for generating the group constants of all core materials as well as the neutronic and steady state thermal hydraulic parameters   were determined by using the MTRDYN code. The calculation results showed that the excess reactivity increases as the uranium density increases since the mass of fuel in the reactor core is increased.  Using the critical velocity concept, the maximum coolant velocity at fuel channel is 11.497 m/s.  The maximum temperatures of the coolant, cladding and fuel meat with the uranium density of 3,66 g/cc are 70.85°C, 150.79°C and 153.24°C, respectively.  The maximum temperatures are fulfilled the design limit so reactor has a safe operation at the nominal power.
