Authors: Mao Xu , Wang Xin , Zhang Jun Chao , Chen Kai , Zhao Jiang , Zhang Yu
Published: August 2013

Nowadays, the operation of orchard vehicle which is used in China has the disadvantages such as single function poor automation level etc. Therefore, it can hardly adapt to the complex environment in orchard. The electric vehicle that powered by electrical drive motor can not only save energy, but also achieve the goal of controlling more conveniently and efficiently. Some electrical vehicles in China can take a variety of steering modes. However, most orchard vehicles lack of targeted terrain design. Electric four-wheel independent drive and steering vehicles have strongly strengthened this weakness. This paper uses four-wheel independent drive & four-wheel independent steering structure and completes the design of the control system. The aim is to achieve five different orchard vehicle driving modes which based on microcontroller system, real-time feedback and achieve differential speed calculating model through the multi-channel sensor in the steering modes. Thus, it can ensure the slip angle within the allowable range and driving stability. It also proposes the design & manufacturing of wireless remote control device and operation panel in order to simplify drivers operation and increase the efficiency.

Authors: Wang Gang , Zhang Yi , Huang Geng Sheng
Published: August 2013

With the growth of urban road traffic volume and the increase of road network density, correlation between adjacent road intersections is becoming more and more obvious. An intersection traffic signal adjustment tends to affect the smooth traffic flow of a number of adjacent intersections. Its congestion may gradually spread to a few blocks and regions all around the intersection. Therefore, increasingly high demands for urban traffic signal control make a variety of advanced control technology integrated, so as to adjust the intersection control parameter and accordingly achieve a dynamic coordination control over the city traffic. Hopefully, it can satisfy traffic demands and achieve a new dynamic balance between road traffic and transport demand. This paper focuses on the signal timing control over green time extension at adjacent intersections of trunk road by using the collaborative strategy of road green wave effect and path selection entropy, in order to solve the problem of coupling between adjacent intersections, so as to realize the signal coordination control on trunk road. This algorithm makes Signal Timing more flexible.

Published: August 2013

Although, on-off control robot gripper is widely employed in pick-and-place operations, it can not be applied in fragile or soft objects handling. Here, an intelligent gripper is designed with embedded distributed control structure for overcoming the uncertainty of grasped object mass and soft/hard features. An efficient model-free intelligent fuzzy sliding mode control strategy is employed to design the position and force controllers of gripper, respectively. Experimental results of pick-and-place soft and hard objects with grasping force auto-tuning and anti-slip control strategy are shown by pictures to verify this distributed system performance. The position and force tracking errors are less than 1 mm and 0.1 N, respectively.
Surface Roughness in Incremental Sheet Metal Forming of AA5052
Authors: Lasunon On Uma
Published: August 2013

This paper presents the effect of forming parameters on the arithmetic mean surface roughness (Ra) of aluminum alloy built by a single-point incremental sheet metal forming process. Three investigated parameters are feed rate (12.5, 25 and 50 in/min), depth increment (0.015 and 0.030 in), and wall angle (45° and 60°). The results show that wall angle, depth increment and its interaction play an important role on the surface roughness, while feed rate has little effect. The optimal forming conditions for minimum surface roughness are feed rate of 25 in/min, depth increment of 0.015 in and wall angle of 45°.

Published: August 2013

Unidirectional interleaving painting is presented for robot to spray long and narrow duct. It adopts a same overlapping distance and only two seed paths in the same direction which are used in turn.To optimize robot trajectory for spray painting, uniformity model of unidirectional interleaving painting based on parabolic deposition model and thickness variance is built, and coating uniformity is studied. Non-dimensional calculation results show that overlapping distance and interleaving distance are the main influencing factors of coating uniformity. The value of thickness deviation is not greater than 0.000 9 in four areas, two of which should be chosen to plan painting path for better coating uniformity. The comparison experiment confirms that interleaving painting can improve coating uniformity.
Refractive Index Sensors Based Resonant Coupling in Solid-Core Photonic Band-Gap Fibers
Authors: Xiao Yue Yu , Wang Hong Wei
Published: August 2013

A novel refractive index sensor based on the resonant coupling mechanism is proposed. The sensor consists of a standard index-guiding solid fiber core and several periodically distributed micro fluidic channels. When the channels are infiltrated with high-index fluid, the resonant coupling between the core mode and cladding modes makes the sensing fiber to be a stop-band filter. Since the filtering effect introduced by the photonic band-gap of the cladding is sensitive to the refractive index of the measurand, numerical results reveal that the sensitivity of the sensor could reach 17250nm/RIU, which is much higher than traditional refractive index fiber sensors.

An Investigation on the Interfacial Transition Zone of Lightweight Aggregate Concrete
Authors: Yang Hsi Chi , Cheng Miao Ying
Published: August 2013

The technique of linking the SEM photographs taken around the interfacial transition zone area is applied to observe the development of hydration products for lightweight aggregate and paste at the different curing ages. This research first determines the mixture proportions of the two types of concrete specimens with different aggregate unit weights. The lightweight aggregate used is the sludge kilned aggregate from Shihmen reservoir. The very small SEM samples to be observed are taken from the concrete compressive test specimens and must include both aggregate and paste. The research then observes the hydration products (such as CH, C-S-H) of calcium ion and the pozzolanic reaction on the samples. Finally it assesses if the aggregate will produce ion exchange with cement and generate the hydration products. The hydration products on either side of the interface with a range of 100μm are observed using 2000x magnification. From the results, it is found that (1) the development of hydration products of the lightweight aggregate concrete is similar to that of the normal-weight aggregate concrete, (2) the failure at the 91 days age is that the lightweight aggregate is sheared, (3) the bond stress of aggregate and paste is controlled by hydration products of paste, (4) the aggregate has not interacted with cement paste to produce hydration products, and (5) the development of hydration products proves that the amount of binder used in the concrete specimen will affects its compressive strength.

Published: August 2013

The double-walled steel vessel filled with insulation powder in the space between two walls was used to minimize heat transfer by radiation and conduction in cryogenic storage tank. And, evaluation of the insulation effect by the thermal conductivity of perlite powder and the effect of heat flux by welding conditions were carried out with insulation analysis of double-wall. The solid supports were also used to bear the weight of the inner container. Furthermore, thermal and structural analysis of the tank was performed to study the effect of vacuum and weldment geometry of the internal supports. If the degree of vacuum were low, the thermal conductivity of perlite increases rapidly and the heat flux should be increased in proportion to the thermal conductivity. Two types of solid supports did not show significant differences in the aspect of working stress or heat flux. Therefore, it is considered that the heat flux is less sensitive against the weldment geometry.

Published: August 2013

Overdrive transmission is easy to rattle. In gear system, rotation speed is one of the important parameters affecting gear rattle. A numerical method for gear rattle simulation at different rotation speed is proposed, which combines the model of gear rattle with the actual motion of gears. Aiming at the relative velocity, which is one of the most important parameters to evaluate the intensity of gear rattle, computational simulation and experimental verification is finished about the influence of different rotation speed on gear rattle with error excitation under overdrive. The experiment and simulation results show that with the rotation speed rising, the amplitude of relative velocity of gear rattle increases, which indicates severer gear rattle.
Die Heidelbergse Kategismus oor die mens as beeld van God
Authors: Van Wyk Gabriël M.J.
Published: August 2013

Hierdie artikel fokus op relevante konfessionele standpunte oor die tema van imago Dei in die reformatoriese en voor-reformatoriese teologie wat as historiese en sistematiese kontekstualisering dien vir die daaropvolgende uitleg van die tema soos wat dit in die Heidelbergse Kategismus hanteer word. ’n Bondige bespreking van die histories-kritiese uitleg van Genesis 1:26–27 word aan die orde gestel om as oorgang te dien tot ’n kritiese waardering van die Kategismus vanuit die perspektief van die eietydse teologie. Die uitleg van Genesis 1:26–27 dien as die vernaamste impuls om die tema in die eietydse teologie onbevange en los van die uitsluitende dwang van tradisionele konfessionele geskille aan die orde te stel, maar met inagneming van ’n ryke teologiese tradisie. In wese is die betoog dat die mens as beeld van God geroepe is om God se heerlikheid en eer op aarde uit te dra en hierdie opvatting word ook in die Heidelbergse Kategismus teruggevind.This article focuses on the relevant confessional statements about the theme imago Dei in reformed- and pre-reformed theology that served as the historical and systematic contextualisation of the subsequent interpretation of the theme as it is treated in the Heidelberg Catechism. A concise discussion of the historical-critical interpretation of Genesis 1:26–27 follows in order to serve as a transition to the critical appreciation of the Catechism from the perspective of contemporary theology. The interpretation of Genesis 1:26–27 served as the main impetus for the open-minded discussion of the theme in contemporary theology, apart from the exclusive constraints of the traditional confessional disputes, but with appreciative consideration for our rich theological tradition. In essence, the author argues that all people, because they are created in the image of God, are called upon to glorify God on earth and that this belief is already formulated in the Heidelberg Catechism.
Cytomorphology of unusual primary tumors in the Pap test
Authors: Khalbuss Walid E. , Pantanowitz Liron , Monaco Sara E.
Published: August 2013

Rare entities in the Pap test, which include neoplastic and non-neoplastic conditions, pose challenges due to the infrequent occurrence of many of these entities in the daily practice of cytology. Furthermore, these conditions give rise to important diagnostic pitfalls to be aware of in the Pap test. For example, cases with adenoma malignum (AM) have been called benign. Recognition of these conditions can help correctly interpret Pap tests as abnormal and thereby ensure that patients get appropriately diagnosed. In this paper, we illustrate and discuss selected uncommon primary neoplastic lesions of the cervix and the vagina that may be seen in Pap test, with a focus on cytomorphology, differential diagnosis and the role of possible ancillary studies. These cases include high-grade squamous intraepithelial lesion cells with small cell morphology; small cell carcinoma; large neuroendocrine carcinoma; glassy cell carcinoma; AM; malignant mixed Müllerian tumor; clear cell carcinoma and primary malignant melanoma. Recognition of these rare variants/neoplasms is important so that involved Pap tests are not diagnosed as benign and that patients with these conditions get additional follow-up.
Soul-brother Eugène N. Marais: Some notes towards a re-edit of his works
Authors: Gray Stephen
Published: August 2013

The intention is to survey the current condition of the works of the South African Eugène Marais (1871–1936). This is with a view to alerting the general reader to certain inherited disorganisations which, in the light of professional scholarly and editing standards, need to be recognised and rectified. Marais’s output as a poet and short story writer, as well as the pioneer populariser of nature studies conducted particularly in the Transvaal Highveld after the Second Anglo-Boer War, in both official languages of his day (English and Afrikaans), have ensured him the status of a unique cultural icon. Yet the publishing opportunities open to him in his hand to mouth, haunted career, especially as a journalist, meant his contributions were assembled into book form haphazardly, or remained unrecuperated from often neglected periodicals of the mid-1890s to the mid1930s to which he contributed.
Cultural conflict and shifting identities in Stephen Black’s The Dorp (1920)
Authors: Snyman Salomé
Published: August 2013

This article deals with journalist, dramatist and novelist Stephen Black’s The Dorp (1920), a novel which I regard as the earliest example of what I have named the small-town novel sub-genre of the South African English novel. Other early examples of the small-town novel are Willemsdorp by H.C. Bosman, The Mask by C.L. Leipoldt and Too Late the Phalarope by Alan Paton. Black satirizes the goings-on in a typical South African town called Unionstad. The name of the town reveals the novel’s threefold thematic impulse: an allegorical evocation of the Union Period (1910–48) in South Africa; an ironic-satirical thrust (the Union period was one of increasing political polarization and ultimately, an idealistic vision of cultural-political reconciliation. Unionstad, like the towns in the novels mentioned above, is portrayed as a microcosm of the national macrocosm. The Dorp reveals the ill effects of historical events such as the Boer War and the 1914 Rebellion, specifically the animosity that it created between English and Afrikaner townspeople. Black’s keen awareness and representation of how the political turmoil in the country impacts on the lives of ordinary people and how town culture reflects key aspects of a bigger problem, are the main strengths of the novel. Black’s vision for reconciliation is symbolized by the union in marriage of Anita van Ryn, the mayor’s daughter and Ned Oakley, the English shopkeeper’s son.

Published: August 2013

Amyloid light chain amyloidosis involving the kidneys is not uncommon in patients with monoclonal gammopathy. The mainstay of treatment of amyloid light chain amyloidosis is autologous hematopoietic stem cell transplantation. Evidence that the autologous hematopoietic stem cell transplantation has been successful is the absence of free monoclonal light chains in serum and urine. Herein, we report 2 cases of progressive renal amyloid light chain amyloidosis after autologous hematopoietic stem cell transplantation, documented by kidney biopsy, despite the absence of monoclonal protein in the serum and urine. Kidney function declined progressively in both patients. During that time, numerous immunofixation and protein electrophoresis test results were negative for monoclonal protein, both in serum and urine, concealing the progression of the amyloidosis. We conclude that close monitoring of kidney function is warranted following autologous hematopoietic stem cell transplantation in patients with amyloid light chain amyloidosis, even with negative results from monoclonal protein testing. Unexplained, worsening renal function warrants a kidney biopsy to assess whether retreatment of the monoclonal gammopathy is indicated.

Este artigo analisa, em princípio, os condicionantes sócio-econômicos (escolaridade, renda, e o ocupação) e ambientais (moradia, água, esgoto e lixo) na Favela da Aldeia, localizada no município de Campos dos Goitacases/RJ - Brasil. Destaca-se que ocorre a determinação de condição de classe na distribuição das riquezas produzidas, bem como na distribuição dos recursos recolhidos pelo Estado através dos impostos. Os indicadores de saúde analisados interferem no coeficiente da mortalidade infantil na Favela da Aldeia. Fica evidenciado que a desigualdade sócio-econômico e ambiental está diretamente relacionado à desigualdade na mortalidade infantil quando comparamos o coeficiente da comunidade com o do município. Aponta-se a necessidade de estudos epidemiológicos nas comunidades de baixa renda, visando à identificação de sub-grupos mais vulneráveis à morbimortalidade, bem como a implantação de um projeto que se traduza em um conjunto de medidas político-administrativas comprometidas com a melhoria da qualidade de vida desta população.
Um novo método para caracterização de propriedades mecânicas em materiais cerâmicos
Authors: Carvalho Eduardo A. de
Published: August 2013

As dificuldades de propriedades mecânicas em materiais cerâmicos, seja pela fragilidade intrínseca do material, seja pelo desalinhamento de barras de tração nos métodos tradicionais utilizados para metais, levou à proposição de um novo método de trabalho. O método proposto não se utiliza de contatos mecânicos para a aplicação de carregamento, porém de radiação de uma emissão laser. Aqui é apresentado um caso estudado onde o método determina, com sucesso, a Tenacidade, a Fratura de um corpo de prova em forma de disco feito de nitreto e silício.
Antes de tudo, filosofia: a ecoeducação como proposta pedagógica
Authors: Soffiati Arthur
Published: August 2013

Há notória perplexidade entre os chamados educadores ambientais porquanto não vislumbram com clareza se a questão que lhes é pertinente deve ser abordada na forma de disciplina isolada ou integrada às outras, de maneira informal ou através de projetos. Além do mais, a falta de um necessário conhecimento de filosofia não lhes tem permitido compreender devidamente se a educação ambiental trata-se de um esforço situado num sistema educacional convencional visando lidar com a crise ambiental ou se vem a ser uma proposta abrangente vinculada a um novo paradigma. Tais os temas discutidos neste pequeno artigo.

A crescente importância econômica das pequenas empresas no Brasil a partir da reestruturação industrial
Authors: Silva Neto Romeu e
Published: August 2013

A partir da década de 70, os conceitos de Taylor e Ford, que contaminaram toda a indústria e o consumo mundiais com uma euforia que perdurou absoluta por cerca de cinqüenta anos, deixaram de ser capazes de atender às novas exigências do mercado. Fez-se necessário surgir um novo modelo de desenvolvimento que atendesse a estas novas exigências. Dentre estas, destaca-se a flexibilidade das empresas, que passou a ser exigida pelos clientes através da variedade, personalização ou inovação de produtos, ou através de prazos menores, ritmo de produção, etc. Estas exigências priorizaram uma reestruturação produtiva e organizacional das empresas dos diversos países. No Brasil, esta reestruturação também foi necessária, só que uma década mais tarde. As empresas nacionais conseguiram se adaptar às novas exigências do mercado, mas sua reestruturação provocou impactos diretos e profundos no emprego e na produtividade. Dentre estes impactos, destaca-se a crescente participação das pequenas empresas na economia brasileira.
