REGULARITIES OF MATERIAL DESTRUCTION OF THE IMPACTOR IN REPEATED SINGLE PUNCH
Authors: Bolobov V. , Bin' Le Tkhan'
Published: October 2018

The technique and the results of experiments on the study of the laws of the process of the cone-shaped tip of a freely falling impactor made of 38HM, U8, H12MF steels, subjected to typical heat treatment and additionally treated with cold, when they apply multiple (up to 10000) single impacts on granite under conditions approaching hydraulic impactor peaks. To explain the processes, we used the values of stresses σк, arising at the contact area of  the impactor and the rock, calculated using the developed mathematical model. It has been established that the process of wear of an impactor with multiple single blows proceeds in three stages separated by critical values, , which correspond to the strength characteristics of the material of the impactor demonstrated in these dynamic conditions.With a small number of strokes (n ≤ n*) and the small size of the blunting area (stage I interaction) values σc exceed  of steel and it is exposed to local destruction at the contact site, which is recorded as a significant loss of the impactor’s mass; with n* < n ≤ n** (stage II) the resulting stresses are not enough to destroy the material, but it is enough for its plastic deformation, accompanied by the movement of metal from the central part of the contact area to the peripheral and the destruction of part of the deformed metal by rock; with n > n** (stage III) arising σк do not reach the level and the decrease in the mass of the impactor is determined by the resistance of the steel to abrasion by the products of rock destruction, displaced by the impactor from the well. The treatment of impactors from all tested steels with cold leads to an increase in their wear resistance; The total depth of the holes punctured by the cold-treated H12MF steel impactor at the time of the interruption of the rock penetration is four times higher than that of the 38HM steel impactor subjected to typical heat treatment.
CALCULATIONS OF DYNAMIC OPERATING MODES OF ELECTRIC DRIVES OF SELF-PROPELLED MINING MACHINES
Authors: Eshchin E.
Published: October 2018

The task of improving the calculations of the dynamic modes of electric drives of self-propelled mining machines, particulary, tunneling machines, is considered. Attention is drawn to the possibility to opearte in dynamic modes of a spatial change in the an asynchronous electric motor stator housing position, included in the electric drive, around the axis of its rotor due to the ultimate rigidity of the supports of the mining machine. In connection to this, it is possible to change the absolute angular velocity of rotation of the electromagnetic field of the stator of this electric motor. The necessity of introducing into existing mathematical models that determine the state and behavior of asynchronous electric motors, additional differential and algebraic relations for calculating the absolute speed of the electromagnetic field of the stator and the nature of the motion of the stator housing of the electric motor as part of the mining machine is noted. The results of calculations of the idle start mode of the electric motor of the executive body of the mining combine are shown, showing the difference in the nature of its electromagnetic moment variation, rotor rotation speed, as well as efforts in individual reducer elements of the driving body driving the stator body from similar calculation results without taking into account the stator body movement. The conclusion is made about the possible discrepancy between the calculated and experimental results in the study of the dynamic modes of self-propelled mining machines.

Compensation of offset for SRF-PLL in grid-connected inverters
Authors: Tran Tho Quang , Truong Anh Viet , Trao Hoan Van , Le Phuong Minh
Published: October 2018

The grid-connected inverters that use synchronous reference frame based phaselocked loop SRF-PLL are applied very popular. The function of SRF-PLLs is fast and accurate estimation of frequency, phase angle, and magnitude of grid voltage. The power quality of the current injected into the grid depends on these estimated parameters. The measurements or processes of data conversion can typically introduce the dc offset in the measured grid voltage. The dc offset is one of the reasons for causing errors for the estimated parameters of the grid voltage and causes injected current with harmonic distortions. This paper proposes a technique of dc offset compensation for SRF-PLL based on the Second Order Generalized Integrator (SOGI). The simulation results validated the performance and robustness of the proposed technique.

A RELEVÂNCIA DO PRINCÍPIO DA PROPORCIONALIDADE À EFETIVAÇÃO DO DIREITO AO MEIO AMBIENTE ECOLOGICAMENTE EQUILIBRADO
Authors: Boas Regina Vera Vilas , Werkema Maurício Sirihal
Published: October 2018

O artigo se refere ao princípio da proporcionalidade que é relevante ao Direito. Notadamente para o direito ambiental ele assume papel de grande destaque.  A doutrina alemã subdivide o princípio da proporcionalidade em três subprincípios: adequação, necessidade ou exigibilidade e proporcionalidade em sentido estrito, os quais se referem às etapas que são verificadas na aplicação da proporcionalidade e, estando os três subprincípios presentes, a proporcionalidade é considerada como aplicada, corretamente. O Estado tem a obrigação de proteger de maneira suficiente os direitos fundamentais, alcançando a proporcionalidade, que no sentido positivo atine à proibição da proteção deficiente e que, no sentido negativo, se traduz na proibição do excesso, invocando a adequação do meio utilizado à restrição dos direitos, com a finalidade de alcançar uma necessidade, que deve ser indispensável e realizada pelo modo menos gravoso; e, por fim, a ponderação, atinente à proporcionalidade em sentido estrito, que compreende o direito fundamental, o menos restritamente possível.  Pelo subprincípio da adequação, o Estado deve eleger uma medida restritiva de direitos fundamentais que se mostre apta e idônea para atingir o fim pretendido; pelo subprincípio da necessidade preconiza que a medida adotada é a exigida para atingir o fim, não sendo possível adotar uma outra medida menos restritiva; por derradeiro, a proporcionalidade em sentido estrito exige que entre o meio eleito e o fim pretendido exista uma relação de proporção, isto é, não se pode aceitar uma grande restrição para um fim de pouca importância. O princípio da proporcionalidade é muito importante à efetividade dos direitos fundamentais, o que é manifestado, inúmeras vezes, pela doutrina nacional e pelos julgados das Cortes do Poder Judiciário, notadamente envolventes da concretização do direito fundamental ao meio ambiente ecologicamente equilibrado, sempre, observando a proporcionalidade das medidas de restrição de outros direitos fundamentais necessárias à efetividade pretendida. Ilegítima a restrição de direito fundamental de um particular que não se mostra proporcional ao benefício gerado ao meio ambiente, da mesma maneira que é ilegítima aquela decisão que, a pretexto de não restringir direito fundamental de um particular, gera uma proteção insuficiente do meio ambiente.

Published: October 2018

Objective: To obtain the prevalence of women with lower urinary

tract symptoms (LUTS) in Dr. Cipto Mangunkusumo National Hospital,

Indonesia.

Method: We conducted a descriptive and analytic study with questionnaire-

based data collection. All subjects were interviewed using

the conventional method and International Consultation on Incontinence

Questionnaire (ICIQ) Female LUTS long form validated in Indonesian

language in the gynecology outpatient clinic in Dr. Cipto

Mangunkusumo Hospital.

Result: Using the conventional method, proposing only one question

of urinary disturbance without asking the detailed symptoms, a

low prevalence of LUTS was obtained (17.3%). On the other hand,

with a well-structured questionnaire using ICIQ-FLUTS long form,

the prevalence of LUTS was 95.3%. This result revealed that LUTS

was a common condition among Indonesian women in the study

population with vaginal delivery as the common risk factor.

Conclusion: Screening for LUTS using a structured questionnaire

identified a significantly higher prevalence of LUTS than the conventional

method. The ICIQ-FLUTS long form validated in Indonesian

language is a robust questionnaire that can be recommended for use

in epidemiological research as well as routine clinical practice.

Authors: Sanif Rizal
Published: October 2018

Objective: To evaluate the clinical efficacy, operability, radicality,

toxicity, and incidence of recurrences of neoadjuvant chemotherapy

(NAC) followed by radical hysterectomy (RH) among patients with

stage IIB cervical cancer.

Method: This is an observational clinical study at Dr. Moh. Hoesin

Hospital, Palembang. Data were analyzed from 27 patients who

matched the inclusion criteria and underwent 3 cycles of neoadjuvant

chemotherapy (NAC) with Paclitaxel (75 mg/m2) in combination

with Cisplatin (50 mg/m2) and Docetaxel (75 mg/m2) combined

with Carboplatin (300 mg/m2) according to AUC 6, followed by radical

hysterectomy from January 2012 until December 2013.

Result: The operability rate after NAC was 96.4%. Lymph node metastases

were negative in 75% of patients, and we found bilateral

lymph node metastases in 14.3% of patients. Parametric infiltrations

were negative in 85.7% of the patients, and positive in 14.3% of patients.

No vaginal infiltrations were found. As much as 89.3% of the

patients did not experience any side effect, while anemia and thrombocytopenia

were found in 10.8% of the patients. We found that

7.1% of patients had recurrences within 6 months interval.

Conclusion: NAC followed by radical hysterectomy showed significant

advantages for patients with stage IIB cervical cancer, with

fewer side effects. However, long-term evaluation and a larger number

of patients are required to confirm this result.

Keywords: cervical cancer, neoadjuvant chemotherapy, radical hysterectomy

Authors: Aryati Aryati , Kusumawati Lulut , Sulistyono Agus
Published: October 2018

Objective: To compare the diagnostic value of IGFBP-1 and combined

IGFBP-1-AFP rapid tests in diagnosing premature rupture of

membranes (PROM).

Method: This study was conducted in Dr. Soetomo Hospital in Surabaya

from July to November 2013. The subjects were 52 pregnant

women with presumed PROM diagnosis, which was recorded by

clinical data and sampling of vaginal discharge swab. The diagnostic

value was obtained by comparing the results of IGFBP-1 and combinated

IGFBP-1-AFP rapid tests by standard PROM examination

namely vaginal pooling, litmus paper test and ferning test.

Result: A difference between the diagnostic value of IGFBP-1 and

combined IGFBP-1-AFP rapid tests in diagnosing PROM was

shown, where the sensitivity and specificity of IGFBP-1 rapid test was

85% and 95%, compared to combined IGFBP-1-AFP rapid test,

which was 91% and 95%. The correlation coefficient of combined

IGFBP-1-AFP rapid test with standard PROM examination

(r=0.841, p=0.000) was higher than the correlation coefficient of

IGFBP-1-AFP rapid test with standard PROM examination

(r=0.772, p=0.000).

Conclusion: Combined IGFBP-1-AFP rapid test has a better diagnostic

value than IGFBP-1 rapid test alone.

Keywords: combined IGFBP-1-AFP, IGFBP-1, PROM

Authors: Pradipta Bram , Andrijono Andrijono , Fuady Ahmad
Published: October 2018

Objective: The researchers aim to investigate the relationship between

smoking habit and other factors as prognostic factors of cervical

cancer.

Method: We performed a retrospective and prospective cohort study

with subjects that are stage IIB-IVB cervical cancer patients in Dr.

Cipto Mangunkusumo Hospital followed up from August 2009 to

April 2014. The subjects’medical records were reviewed, and patients

were interviewed about their current condition by telephone. Questions

asked include smoking habit, spouse’s smoking habit, and mortality

status. Patients that could not be contacted by phone were excluded

from the study. Statistical analysis was done using Stata 10.

Result: Out of 390 cervical cancer patients stage IIB-IVB in 2009,

there were 270 patients (69.2%) that were included in the inclusion

criteria. Most of the patients are 40-59 years old (82.2%) and are nonsmokers

(91.8%). The most frequent clinicopathological characteristic

is IIIB (63.3%) and squamous cell carcinoma (71.9%). The 5-

year survival rate is 22.6%. There is no statistical significance between

advanced stage cervical cancer survival with the patients’ or patients’

husbands’ smoking habit.

Conclusion: In our study, smoking habits do not aggravate survival

rate of advanced stage cervical cancer patients but further research

must be done with more sample. Stage, and tumor size both by physical

examination and ultrasound can be used as the prognostic factor.

An Estimation of the Learning Curve Effect on Project Duration with Monte Carlo Simulation
Authors: Mályusz Levente , Varga Anita
Published: October 2018

The aim of this paper is to estimate learning curve effect on project duration with the mean of project scheduling techniques. To measure this effect only one assumption is taken: the activity time individuals / groups take to perform an activity decreases at a given rate as experience is gained with the activity. Unfortunately this effect directly is not taken into account by project management software. In some software after scheduling, supervisor manually can switch on the "as soon as possible" or "as late as possible" buttons on an activity.Monte Carlo simulation was used to model the risks in the total project durations. It is assumed that the (normal) durations of the activities can vary according to the beta distribution. The minimum estimate is 95 % of the original (normal) duration, and the maximum estimate is 140 % of the original (normal) duration. We assumed that most likely value is the (normal) duration of each activity. The learning effect on project duration with the help of test problems and real problems was investigated. In test problems learning effect can occur between two consecutive activities. These pairs are chosen randomly. After calculating project duration, these pairs are allocated to be closer to each other using the predecessor's total float time. It is assumed that the duration of impending repetitive activities is shorter due to the learning curve effect if the gap between consecutive activities is small enough. This iteration is carried out until it is not possible to shorten the successor's activity time in a pair. It is shown that this effect brings a 2-3 % shorter project duration meanwhile variance is also left in a 1-2 % range. Numerical tests were implemented by XPRESS-Mosel Optimization Software.
High-Gain Observer-Based Sliding-Mode Dynamic Surface Control for Particleboard Glue Mixing and Dosing System

Published: October 2018

In the process of particleboard glue mixing and dosing control under the working condition of intermediate frequency, a sliding-mode dynamic surface control strategy based on high-gain observer is proposed in this paper to deal with the problem of glue flow stability caused by strong nonlinearity. The high-gain observer (HGO) is aimed at estimating the derivative of the immeasurable system input signal for feedback, and the robustness of the system is improved by the dynamic surface control (DSC) method. Furthermore, the sliding-mode control (SMC) method is used to deal with disturbances caused by the uncertainties as well as external disturbances. It is proven that the system is exponential asymptotic stable by constructing a suitable Lyapunov function. Simulation results show that the proposed control methods can make the system track the expected flow value quickly and accurately. Finally, numerical simulation results are exhibited to authenticate and validate the effectiveness of the proposed control scheme.
Modelling Carbon Fluxes as an Aid to Understanding Perennial Ryegrass (Lolium perenne) Root Dynamics

Published: October 2018

Despite the importance of roots in determining plant performance, the factors controlling their development and longevity remain poorly understood. Grass morphology is based on repeating units called phytomers, with each capable of producing one leaf, one daughter tiller, and one or more roots. We developed a phytomer-based understanding of root birth, growth and senescence in Lolium perenne, using a modeling approach to explore seasonal effects on root turnover dynamics, and to explore cultivar differences in these processes. Similar to leaves, roots exhibit a clear progression from initiation, growing for approximately seven phyllochrons, with growth rates strongly influenced by environmental conditions. In spring, the phyllochron decreased over the experiment, while it increased in autumn. In spring, C availability exceeding maintenance respiratory requirements allowed root growth at each phytomer position, with a 70/30 split between maintenance and growth. Under C-deficient conditions in autumn, this split was approximately 80/20, with growth limited to younger phytomer positions, while older roots were more susceptible to starvation-induced senescence due to their high C requirements for maintenance respiration.
Does the Optimal Dietary Methionine to Cysteine Ratio in Diets for Growing Chickens Respond to High Inclusion Rates of Insect Meal from Hermetia illucens?
Authors: Brede Anne , Wecke Christian , Liebert Frank
Published: October 2018

The dietary methionine:cysteine (Met:Cys) ratio (MCR) is an important factor influencing the optimal growth of chickens. Therefore, this study aimed to contribute to the assessment of the optimal dietary MCR in diets with the complete replacement of soybean meal (SBM) by a partly defatted larvae meal of Hermetia illucens (HM). A growth study with 240 male meat-type chickens (Ross 308) was conducted, also assessing the body nutrient deposition both at the end of the starter (day 21) and the grower (day 35) period. Birds were fed experimental diets based on wheat, maize, and insect meal (23%/21% HM in starter/grower diets). Sulfur amino acids were created as the limiting AA in diets with graded MCR (40:60; 45:55; 50:50; 55:45; 60:40). The control diet contained SBM instead of HM with a MCR of 50:50. The current results based on growth parameters, dietary protein quality, and Met efficiency data gave support to the previous assumption of an ideal MCR of 50:50, which was also valid in diets with a high proportion of insect meal. The lowest MCR of 40:60 led to significantly impaired feed intake and growth of the birds, while the response to the highest MCR (60:40) was moderate.

Published: October 2018

Based on the first-principles of density functional theory, the SF6 decomposition products including single molecule (SO2F2, SOF2, SO2), double homogenous molecules (2SO2F2, 2SOF2, 2SO2) and double hetero molecules (SO2 and SOF2, SO2 and SO2F2, SOF2 and SO2F2) adsorbed on Pt doped graphene were discussed. The adsorption parameters, electron transfer, electronic properties and energy gap was investigated. The adsorption of SO2, SOF2 and SO2F2 on the surface of Pt-doped graphene was a strong chemisorption process. The intensity of chemical interactions between the molecule and the Pt-graphene for the above three molecules was SO2F2 > SOF2 > SO2. The change of energy gap was also studied and according to the value of energy gap, the conductivity of Pt-graphene before and after adsorbing different gas molecules can be evaluated.
3-D People Counting with a Stereo Camera on GPU Embedded Board

Published: October 2018

People counting in surveillance cameras is a key technology for understanding the flow population and generating heat maps. In recent years, people detection performance has been greatly improved with the development of object detection algorithms using deep learning. However, in places where people are crowded, the detection rate is low as people are often occluded by other people. We proposed a people-counting method using a stereo camera to resolve the non-detection problem due to the occlusion. We applied stereo matching to extract the depth image and convert the camera view to top view using depth information. People were detected using a height map and an occupancy map, and people were tracked and counted using a Kalman filter-based tracker. We operated the proposed method on the NVIDIA Jetson TX2 to check the real-time operation possibility on the embedded board. Experimental results showed that the proposed method had higher accuracy than the existing methods and that real-time processing is possible.
Differential Learning for Outliers: A Case Study of Water Demand Prediction
Authors: Shah Setu , Ben Miled Zina , Schaefer Rebecca , Berube Steve
Published: October 2018

Predicting water demands is becoming increasingly critical because of the scarcity of this natural resource. In fact, the subject was the focus of numerous studies by a large number of researchers around the world. Several models have been proposed that are able to predict water demands using both statistical and machine learning techniques. These models have successfully identified features that can impact water demand trends for rural and metropolitan areas. However, while the above models, including recurrent network models proposed by the authors are able to predict normal water demands, most have difficulty estimating potential deviations from the norms. Outliers in water demand can be due to various reasons including high temperatures and voluntary or mandatory consumption restrictions by the water utility companies. Estimating these deviations is necessary, especially for water utility companies with a small service footprint, in order to efficiently plan water distribution. This paper proposes a differential learning model that can help model both over-consumption and under-consumption. The proposed differential model builds on a previously proposed recurrent neural network model that was successfully used to predict water demand in central Indiana.

Published: October 2018

The popular and widely reported lithium-ion battery model is the equivalent circuit model (ECM). The suitable ECM structure and matched model parameters are equally important for the state-of-charge (SOC) estimation algorithm. This paper focuses on high-accuracy models and the estimation algorithm with high robustness and accuracy in practical application. Firstly, five ECMs and five parameter identification approaches are compared under the New European Driving Cycle (NEDC) working condition in the whole SOC area, and the most appropriate model structure and its parameters are determined to improve model accuracy. Based on this, a multi-model and multi-algorithm (MM-MA) method, considering the SOC distribution area, is proposed. The experimental results show that this method can effectively improve the model accuracy. Secondly, a fuzzy fusion SOC estimation algorithm, based on the extended Kalman filter (EKF) and ampere-hour counting (AH) method, is proposed. The fuzzy fusion algorithm takes advantage of the advantages of EKF, and AH avoids the weaknesses. Six case studies show that the SOC estimation result can hold the satisfactory accuracy even when large sensor and model errors exist.
