Published: March 2016

The work is devoted to the virtual simulation of a sheet roll working layer formation at a technological stage “casting-solidification”. To form a virtual model of a roller mould pouring and foundry solidification there was used a computer modeling system (CMS) which included initial and boundary conditions for a roller mould pouring process with highalloy cast iron in the field of centrifugal force action. The distribution of a metal working layer along an inner surface of a rotating mould at different technological parameters: mass of highalloy cast iron, its density, temperature and pouring velocity, temperature of metal and non-metal parts of a mould at the initial point of time, modes of rotation and conditions of mould cooling and others were investigated. It is established that under the influence of centrifugal forces a free surface of liquid melt obtains a parabolic form. The influence of basic technological parameters upon the vertex position of a paraboloid of revolution of highalloy liquid melt z0 is revealed. It is shown in the paper that it stipulates for the unevenness of a working layer value along a roller barrel. As a result of computations it is obtained that the value of a working layer at lower flanks of barrels is higher than that of upper sides. The average value of such an exceeding makes 0.012 m. As a result of a simulation analysis of a foundry formation process at different technological parameters it is determined that the distance increase between the vertex of a paraboloid of revolution and the metal area investigated raises the working layer evenness along a roller barrel 3.6 times. Hence, the increase of capacity for work of a rolling tool is expected. The results of investigations presented are basic for the works for the increase of centrifugal roller servicing characteristic increase.

Published: March 2016

The dimensionaltopological parameters of a structure such as size, shape, quantity and distribution characterizing a graphite phase in cast iron exert a significant influence upon material properties. But, the definition of these parameters according to the system presented in SARS 3443-87, to the considerable extent, depends upon human factor. The use of results of such an analysis does not allow creating adequate simulators for the estimation of correlation of structure and properties. The widespread introduction of computer analysis methods for the control of material structures dictates new requirements to the development of methods using a mathematical description of material phase structure. One of the methods based on a multifractal analysis of cast iron microstructure representation is shown in this paper. Data obtained at the use of carbon fleck fractal identification method can be used at the development of simulators of the correlation in structure graphitized cast iron properties.

THEORETICAL DEFINITION FOR QUALITY PARAMETERS OF SURFACE LAYER IN PARTS, TOOL-ELECTRODE WEAR AND PROCESS PRODUCTIVITY AT ELECTROEROSION MACHINING
Authors: Съянов Сергей , Syanov Sergey
Published: March 2016

An electric erosion process serves as a basis for electroerosion machining (EEM) as a result of which occurs a material removal from the surface of a product. The destruction of electrode surface takes place at the expense of melting and partial evaporation of material. As a result of this the cavities called holes remain on a surface and also changes arise on the surface layer of a billet. A microrelief of a surface is formed with considerable quantity of mutually covered holes having different geometrics the knowledge of which allowed determining height and pitch parameters of roughness. Upon a corrugation formation at electroerosion machining has an influence a lot of factors which may be or may be not depending on a machining procedure and on whether machining is to be carried out on solid material or a surface prepared earlier should be machined. To the basic factors affecting the surface corrugation at EEM should be referred parameters conditioned on the influence of a billet initial corrugation, tool initial corrugation, influence of fluctuations in technological modes of machining. Having defined these parameters it should be possible to compute a corrugation at EEM. To analyze microhardness and residual stresses at EEM, first, it should be necessary to know a temper-ature field distribution in the surface layer of a product that will allow defining quality parameters mentioned above. To determine volumetric wear of a tool-electrode and EEM productivity it should be necessary to know the following: physical stress-strain properties of work material and material of a tool-electrode; modes of electro-erosion machining; properties of dielectric liquid.

Published: March 2016

It is wellknown that at long braking and parking of a train or a single railroad car the air pressure in brake cylinders and control reservoirs gradually drops because of air leaks that results in exhaustion of brake as a consequence of this a rollingstock can start spontaneous motion which can cause severe damages and accidents. It is a substantial drawback in an indirectacting automatic brake. To eliminate such a drawback there was developed a promising brake design at the level of an invention in Bunin ESU and a set of computations for the substantiation of rational parameters for a springing element excluding the cessation of brake functioning and hence a possibility for spontaneous rollingstock motion.

Published: March 2016

Under presentday conditions the main constituent in the competitiveness of any enterprise – a capaci-ty for ensuring ever-growing requirements of a con-sumer market and concrete customers to produce quality. One of the ways to solve this not simple problem is the development and introduction of an ever-improving system of quality management (SQM) meeting the highest international requirements. A significant requirement of international standards is the application in SQM a procedure of the FMEA-analysis of kinds and consequences of failures which is used for more than half a century abroad at the creation of complex engineering systems.

To date a considerable urgency gains the introduction of the complex FMEA-methodology including the fulfillment of a product design analysis, the PFMEA-analysis of the product manufacturing method and the MFMEA-analysis of equipment (rigging). The peculiarity of such a complex analysis consists in the hierarchy and consistency of the ful-fillment various kinds of FMEA: FMEA of product – FMEA of an assembly (A) – FMEA of a part. All kinds of FMEA are connected and depend on each other. The FMEA result of product and assembly design is a basis for the FMEA of product and unit assembly. It is evident that the last should be carried out after the introduction of changes in the design of a unit according to the FMEA results of design. The FMEA of equipment should be carried out after the introduction of changes in an engineering procedure according to the FMEA results of a process. Taking into account this, first should be carried out the FMEA of a design and the FMEA of a process and the FMEA of equipment should complete the consistency of tests. The paper reports thoroughly the first two stages of the complex FMEA-analysis.
Improved and Generalized Upper Bounds on the Complexity of Policy Iteration
Authors: Scherrer Bruno
Published: March 2016

Given a Markov decision process (MDP) with n states and a total number m of actions, we study the number of iterations needed by policy iteration (PI) algorithms to converge to the optimal γ-discounted policy. We consider two variations of PI: Howard’s PI that changes the actions in all states with a positive advantage, and Simplex-PI that only changes the action in the state with maximal advantage. We show that Howard’s PI terminates after at most O((m/(1 − γ))log(1/(1 − γ))) iterations, improving by a factor O(log n) a result by Hansen et al. [Hansen TD, Miltersen PB, Zwick U (2013) Strategy iteration is strongly polynomial for two-player turn-based stochastic games with a constant discount factor. J. ACM 60(1):1:1–1:16.], whereas Simplex-PI terminates after at most O((n m/(1 − γ))log(1/(1 − γ))) iterations, improving by a factor O(log n) a result by Ye [Ye Y (2011) The simplex and policy-iteration methods are strongly polynomial for the Markov decision problem with a fixed discount rate. Math. Oper. Res. 36(4):593–603.]. Under some structural properties of the MDP, we then consider bounds that are independent of the discount factor γ: quantities of interest are bounds τt and τr—uniform on all states and policies—respectively, on the expected time spent in transient states and the inverse of the frequency of visits in recurrent states given that the process starts from the uniform distribution. Indeed, we show that Simplex-PI terminates after at most Õ(n3m2τtτr) iterations. This extends a recent result for deterministic MDPs by Post and Ye [Post I, Ye Y (2013) The simplex method is strongly polynomial for deterministic Markov decision processes. Khanna S, ed. Proc. 24th ACM-SIAM Sympos. Discrete Algorithms, SODA '13 (SIAM, Philadelphia), 1465–1473.] in which τt ≤ 1 and τr ≤ n; in particular it shows that Simplex-PI is strongly polynomial for a much larger class of MDPs. We explain why similar results seem hard to derive for Howard’s PI. Finally, under the additional (restrictive) assumption that the state space is partitioned in two sets, respectively, states that are transient and recurrent for all policies, we show that both Howard’s PI and Simplex-PI terminate after at most Õ(m(n2τt + nτr)) iterations.

Published: March 2016

The objective of the present study was to examine the growth responses of Acacia mangium (mangium) and Paraserianthes falcataria (sengon) seedlings growing on different soil origin under nursery condition. This study was started in September 2012 and terminated in March 2013.  The seedlings were grown from seeds sown in a plastic box filled with sterilized sands. One week after sowing, the seedlings were transplanted into polybags contained sterilized soils originated from secondary forest, Imperata cylindrica grassland and ex-coal mining. The number of all seedlings were 180 seedlings consisted of 3 different soils, 2 species of seedlings with 10 seedlings replicated 3 times. Assessment was conducted one week after transplanting, then subsequently monitored every 2 weeks, except dry weighing and counting nodules were performed at the end of the study. A completely randomized design was used in this study. The data was analyzed using Costat software. The study resulted that the different of soil origin influenced on all growth variables of mangium and sengon of 4.5 months old. The survival rate of seedlings, height and diameter increments, dry weight and root nodules were better in both species of seedlings growing on soil originated from secondary forest and Imperata grassland compared with the soil from ex-coal mining. But the survival rates of sengon seedlings were higher than that of mangium on these three soils. The highest dry weight of sengon seedlings was achieved on soil originated from secondary forest. In the present study, soil originated from secondary forest increased more in weight of shoot than root, so that the shoot-root ratio was unbalanced more than one. Based on the results of this study, it is recommended that soil from secondary forest and Imperata grassland can be used as growing media for mangium and sengon seedlings in the nursery.

Authors: Gertsman Ilya , Johnson Wynonna S , Nishikawa Connor , Gangoiti Jon A , Holmes Bonnie , Barshop Bruce A
Published: March 2016

BACKGROUND

Cystine determination is a critical biochemical test for the diagnosis and therapeutic monitoring of the lysosomal storage disease cystinosis. The classical mixed-leukocyte cystine assay requires prompt specialized recovery/isolation following blood drawing, providing cystine concentrations normalized to total protein from assorted types of white blood cells, each with varying cystine content.

METHODS

We present a new workflow for cystine determination using immunomagnetic granulocyte purification, and new reference ranges established from 47 patient and 27 obligate heterozygote samples assayed. Samples were collected in acid-citrate dextrose tubes and their stability was proven to allow for overnight shipping before analysis. Cystine was quantified by LC-MS/MS.

RESULTS

The new method was reproducible (<15% root mean square error) and specific, assaying purified granulocytes from blood samples that no longer required immediate preparation and therefore allowing for up to 30 h before processing. There was a nearly a 2-fold increase in the therapeutic target (1.9 nmol half-cystine/mg protein) range, established using distributions of patient, obligate heterozygote, and control samples. The 2.5–97.5 percentile ranges (−2 SD to +2 SD around mean) for these cohorts were 0.67–6.05 nmol/mg protein for patients, 0.33–1.35 nmol/mg protein for obligate heterozygotes, and 0.09–0.35 nmol/mg protein for controls.

CONCLUSIONS

The intracellular cystine determination method using immunopurified granulocytes followed by LC-MS/MS analysis improves the inherent variability of mixed leukocyte analysis and eliminates the need for immediate sample preparation following blood draw.

Published: March 2016

O defeito zero é algo praticamente inalcançável em operações de serviços, o que torna a capacidade das empresas de gerenciar eficazmente as reclamações dos clientes oriundas das falhas de serviços uma condição sine-qua-non para o seu sucesso no longo prazo. Este artigo tem como objetivo central avaliar a influência das percepções de justiça na satisfação dos clientes após a condução de um processo de gerenciamento de reclamações. Para tanto, foi analisado o caso de uma empresa de telefonia celular a partir da condução de uma survey com 496 clientes que reclamaram no seu call center. Foram avaliadas as percepções individuais de justiça declaradas pelos clientes e a sua relação com a satisfação após o processo. Os resultados obtidos por meio da aplicação de Regressão Logística demonstram que as percepções de justiça processual e distributiva influenciaram de forma significativa a satisfação, enquanto que a justiça interpessoal, apesar de ter obtido a melhor avaliação individual, não demonstrou ter relação significativa com este construto. São feitas reflexões relevantes baseadas nestes resultados, considerando que diversos elementos de justiça mal avaliados individualmente apresentaram grande influência na satisfação final e indicando a necessidade da empresa em rever suas prioridades em termos de revisão de processos e treinamento de funcionários.

Geralmente, a implementação do Lean Manufacturing (LM) se inicia com o Mapeamento do Fluxo de Valor (MFV). O objetivo deste trabalho é apresentar a aplicação do MFV, associado à simulação, a fim de analisar os impactos da adoção do LM no desempenho de uma empresa calçadista. Então, realizou-se um MFV do estado atual e, por meio da implantação de elementos da abordagem lean, pôde-se construir o MFV do estado futuro. Diferentes cenários foram simulados para a implementação do estado futuro e tiveram seus resultados comparados. As etapas produtivas simuladas foram o transfer, o corte e a montagem, visto que se considerou que entre esses processos poderia ser estabelecido um fluxo unitário do produto. Após a simulação, o cenário que apresentou melhores resultados proporcionou um aumento de produtividade de 19% em relação ao estado atual, além de melhoria em todas as outras variáveis que foram comparadas. A aplicação da simulação como um elemento adicional do MFV ajudou a identificar as vantagens da abordagem conjunta, uma vez que a mesma possibilita testar diferentes alternativas e definir melhor o estado futuro e suas estratégias de implementação.

The purpose of this study was to determine the relationship between stigma levels of teachers and teachers’ organizational justice perceptions. Relational survey model was used in research. Teachers’ opinions on stigma level and organizational justice were reviewed. A total of 204 public school teachers (elemantary and high) employed in Ankara participated in the study. The "Stigma Scale” developed by Yaman and Güngör (2013) and "Organizational Justice Scale”developed by Hoy and Tarter (2004) were used to gather data. The data was analyzed by using Pearson Product-Moment Correlation Coefficient, Descriptive Statistics (frequency, percentage, arithmetic average, standard deviation), and multiple regression analysis techniques. Results indicated that teachers’ stigma scores were high in prejudice and psychological health  and the participants had positive perceptions about organizational justice at public schools. There was meaningful negative relationship between stigma levels of teachers and organizational justice perceptions of teachers. Consequently, stigma level is one of the factors that affect organizational justice negatively in schools. ÖzetBu araştırmanın amacı, Ankara Büyükşehir Belediyesi sınırları içerisinde bulunan merkez ilçelerdeki resmi ilköğretim ve ortaöğretim kurumlarında görev yapan öğretmenlerin görüşlerine göre, öğretmenlerin damgalama düzeyleri ile örgütsel adalet algıları arasındaki ilişkiyi saptamaktır.

Koridor Jatingaleh merupakan salah satu titik macet di Kota Semarang. Terjadinya kemacetan di kawasan ini disebabkan karena volume kendaraan yang melampaui kapasitas jalan yang ada. Oleh karena itu perlu dilakukan pembangunan jalan simpang tidak sebidang (flyover atau underpass) guna mengatasi kemacetan di Koridor Jatingaleh. Selanjutnya perlu dikaji pula, alternatif jalan simpang tidak sebidang mana yang lebih sesuai untuk dibangun? Flyover atau Underpass? Oleh karena itu, penelitian ini bertujuan untuk mengkaji alternatif jalan simpang tidak sebidang yang sesuai dari aspek ekonomi guna menangani kemacetan di koridor Jatingaleh. Penelitian ini menggunakan pendekatan kuantitatif. Hasil penelitian yang didapatkan adalah pembangunan underpass lebih hemat dibandingkan dengan pembangunan flyover. Kondisi tersebut ditinjau dari perhitungan nilai waktu, BOK dan biaya pemeliharaan dan juga pengaruhnya bagi struktur ruang kawasan sekitarnya.  Dengan demikian, dapat diketahui jalan simpang tidak sebidang yang sesuai dari aspek ekonomi di koridor Jatingaleh adalah underpass.

Letak kedekatan lokasi geografis dengan lempeng tektonik Eurasian dan Indo-Australian membawa konsekuensi logis terhadap tingginya resiko kebencanaan, terutama gempa dan tsunami, bagi Indonesia. Kota Mataram yang merupakan ibukota Provinsi Nusa Tenggara Barat merupakan salah satu wilayah yang perlu mendapatkan perhatian khusus terhadap resiko bencana tsunami. Sebagai langkah awal, identifikasi lokasi yang paling rentan terhadap resiko bencana tsunami perlu dilakukan dengan memadukan aspek-aspek fisik, sosial dan ekonomi. Penelitian ini bertujuan mengidentifikasikan lokasi paling rentan terhadap resiko bencana tsunami di Kota Mataram dengan menggunakan analisa sistem informasi geografis (GIS). Penilaian dilakukan dengan mengembangkan Indeks Gabungan (Composite Index) berupa Total Vulnerability Index (TVI) yang merupakan kombinasi Indeks Kerentanan Fisik/ Physical Vulnerability Index (PVI), Indeks Kerentanan Sosial/ Social Vulnerability Index (SVI) dan Indeks Kerentanan Ekonomi/ Economic Vulnerability Index (EVI). Hasil analisis berhasil menemukenali bahwa Kota Tua Ampenan merupakan wilayah di Kota Mataram dengan nilai indeks gabungan tertinggi yang mencerminkan tingkat kerentanan yang paling tinggi.

Authors: Yunianto Bambang , Septiani Dwi
Published: March 2016

Beberapa metode penghemat bahan bakar pada kompor gas  telah dibuat dan diuji cobakan salah satunya adalah  penggunaan penghemat bahan bakar elektrolizer. Prinsip alat ini adalah proses elektrolisis dengan dua elektroda yang dimasukkan didalam larutan elektrolit (campuran air-NaOH). Dengan dialiri arus listrik DC pada dua elektrode,  akan timbul gas HHO (gas Brown)  yang bersama-sama dengan gas LPG dapat meningkatkan proses pembakaran dalam kompor gas. Dengan memvariasikan konsentrasi NAOH dalam larutan maka akan terjadi perubahan efisiensi pembakaran. Dalam pengujian dihasilkan bahwa pada kosentrasi NAOH 33 % dan arus DC 1.7 Ampere, diperoleh peningkatan efisiensi pembakaran tertinggi, yaitu didapat penghematan gas LPG hingga 19 %.

Dewasa ini, industri dihadapkan pada tekanan untuk mengurangi konsumsi energi dan memperpanjang umur komponen dalam usaha untuk mengurangi biaya produksi dan dampak lingkungan. Sudah umum diketahui bahwa permukaan slip pada slider bearing dapat memperkecil gaya gesek sekaligus meningkatkan daya dukung beban. Selain itu, pemberian recess pada permukaan juga dapat meningkatkan performansi pelumasan. Dalam tulisan ini, analisis CFD hidrodinamika pada slider bearing dilakukan untuk memperoleh performansi pelumasan yang efektif. Dua bentuk recess (persegi dan trapesium) dan area permukaan slip/no-slip dibandingkan. Hasil simulasi menunjukkan bahwa pemberian slip dengan desain area tertentu pada bearing memberikan hasil performansi yang lebih baik dibandingkan kondisi no-slip. Selain itu, pemberian recess berbentuk trapesium yang dikombinasikan dengan slip terbukti menghasilkan daya dukung beban yang besar dan gesekan yang kecil

KARAKTERISASI RODA GIGI PRODUK UKM UNTUK ANTISIPASI PASAR GLOBAL ASEAN
Authors: Sugiyanto Sugiyanto
Published: March 2016

Roda gigi merupakan komponen penting dalam industri otomotif. Permintaan pasar komponen otomotif domestik, termasuk roda gigi, meningkat sangat tajam, sehingga banyak UKM turut memasuki pasar tersebut. Hal yang sangat disayangkan adalah roda gigi produk UKM berkualitas rendah sehingga tidak dapat diterima oleh pasar. Faktor utama yang mempengaruhi kualitas roda gigi UKM adalah kekerasan permukaan dan ketahanan lelah. Hal ini terjadi karena kurangnya penerapan teknologi tribologi dan perlakuan panas. Penelitian ini bertujuan untuk mendapatkan data karateristik kualitas roda gigi produk UKM dengan melakukan uji kekasaran permukaan gigi, uji kekerasan dari permukaan gigi sampai kedalaman tertentu dan uji struktur mikro. Guna mengetahui kualitas roda gigi produk UKM kita bandingkan dengan roda gigi OEM (original equipment manufacturer) buatan produsen sepeda motor. Dengan membandingkan hasil uji dari kedua roda gigi tersebut diperoleh posisi kualitas roda gigi produk UKM. Hal ini sangat penting guna melakukan penelitian selanjutnya dalam rangka peningkatan kualitas roda gigi produk UKM. Hasil yang diperoleh menunjukkan bahwa roda gigi produk UKM memiliki kualitas yang lebih rendah daibandingkan roda gigi produk OEM. Hal ini disebabkan roda gigi produk UKM biarpun menggunakan bahan baku standar masih memiliki kekasaran permukan yang lebih kasar dari produk OEM sehingga menimbulkan suara yang lebih berisik pada saat digunakan. Selain itu hasil pengerasan permukaan roda gigi produk UKM kekerasannya sampai di tengah roda gigi sehingga menurunkan kemampuan roda gigi dalam menerima beban. Dari hasil uji struktur mikro menunjukkan bahwa struktur mikro roda gigi UKM terdiri dari proeutectoid ferrite (untuk baja hypoeutectoid, 0,44 wt%C) dan pearlite (α, ferrite + Fe3C, cementite), kondisi struktur mikro tersebut terjadi mulai dari ujung gigi sampai bagian terdalam roda gigi, hal ini sesuai dengan kondisi proses pengerasan yang dilakukan
