A Novel Extended Expansion Engine Mechanism
Authors: Arabacı Emre
Published: June 2018

Due to the increasing population and intense energy consumption,
energy efficiency and efficient use of energy in the power units in the vehicle
are important concepts for our earth. Particularly in hybrid engine vehicles
produced in recent times, Atkinson (or Miller) internal combustion engines are
preferred over conventional internal combustion engines. Atkinson's work from
1882 to the present day in many extended expansion engine mechanism design is
presented. This paper deals with the design of a novel extended expansion
engine mechanism that is intended to achieve trefoil hypotrochoid curve motion
in the crankshaft connection using the planetary gear system. The kinematic
equations related to the presented new crank-conrod mechanism have been
obtained and compared with the conventional crank-conrod mechanism. As a result
of the paper, the equations required for kinematic analysis were derived, and
the kinematic data of the novel designed mechanism were compared and evaluated
according to the data of the conventional system. As a result of this
evaluation, it was shown that the desired extended expansion stroke could be
obtained by using this mechanism and the parameters affecting the kinematic
analysis were determined. However, it has been seen that by changing the
critical design parameters, different piston path can be achieved with the
novel designed mechanism.

Corrosion causes great losses and catastrophic damages in industrial plants and infrastructure, among the methods to reduce it are the coatings. The use of metal-ceramic multilayer coatings to reduce corrosion in steels is a viable option, since they offer several advantages over single-layer coatings, among which, they can be deposited with relatively high thicknesses and are able to dissipate the residual stresses that form during the growth of the thin films, which maintains its adhesion to the substrate. The coatings were deposited by magnetron Sputtering, using Ti and W targets. Two multilayer architectures were designed and deposited, including tungsten nitride (WN) and titanium tungsten nitride (WTiN) coatings with alternated bilayers of Ti/TiN and W/WN, those two deposition sequences of layer were identified as A with more Ti and B layers with higher W content; both consist of a nine-layer deposit process. The structure was studied by X-ray diffraction and the morphology and composition by SEM and EDS respectively. The surface was studied with profilometry and atomic force microscopy. The electrochemical behavior was analyzed in a sodium chloride solution by means of potentiodynamic polarizations and electrochemical impedance spectroscopy (EIS). X-ray diffraction results show the presence of two phases of WN. The grain size of coating A is similar to that obtained in coating B. The morphology of the multilayers showed a mostly smooth surface but with the presence of spherical domes, as well as cracks in both coatings, being more abundant in the coating B. In its cross section, the sequence of multilayers composed of layers of Ti, W, TiN, WTiN and WN is observed, however in some cases the change between the individual layers is not observed and two layers remain as one in the images of MEB. The electrochemical results obtained by potentiodynamic polarization curves showed a shift of the corrosion potential towards more noble values. The corrosion current in coating A with more layers of Ti is lower than coating B and both improve the corrosion resistance of the substrate. This behavior was confirmed in the Nyquist diagram obtained by EIS.
Non-linear radiation influence on oblique stagnation point flow of Maxwell fluid
Authors: Ghaffari Abuzar , Javed T. , Mustafa I.
Published: June 2018

Non-linear thermal radiation effects on non-aligned stagnation point flow of Maxwell fluid have been carried out in the present investigation. It is observed that the non-linear radiation augments the temperature and heat transfer rate. This physical phenomenon is translated into a system of partial differential equations (PDEs). After useful transformation, these non-linear constitutive equations are transformed into a system of ordinary differential equations (ODEs) and interpreted numerically by means of parallel shooting technique. Effects of pertinent parameters on flow and heat transfer are elaborated through tables and graphs. It is observed that radiation and surface heating enhance the rate of heat transfer, however Prandtl number has inverse relation with thermal boundary layer thickness. It has been observed that for increasing Prandtl number, heat transfer rate enhances. The detailed discussion of heat transfer rate is also presented in this study. Flow pattern is judged through streamlines graphs. It is also observed that oblique stagnation point flow behaves like orthogonal stagnation point flow, when free stream velocity is very large as compared to stretching velocity.

Published: June 2018

Kurzfassung

Das Wertstromdesign ist eine etablierte Methode zur Entwicklung des Soll-Zustands eines Wertstroms. Durch die Möglichkeiten der Digitalisierung und Industrie 4.0 ergeben sich neue Anforderungen an ein Wertstromdesign. Es müssen beispielsweise die informationstechnische Vernetzung von Elementen des Wertstroms und der zunehmende produktspezifische Informationstransport stärker berücksichtigt werden. Hier stoßen vorhandene Methoden an ihre Grenzen, da der Fokus auf der Gestaltung von Materialflüssen liegt oder Informationsflüsse nicht im notwendigen Umfang betrachtet werden [1, 2]. Die in diesem Beitrag vorgestellte Methode setzt an genau dieser Stelle an und zeigt ein systematisches und auf den Wertstrom ausgerichtetes Vorgehen, welches die Integration digitaler Technologien, die die Gestaltung von Informationstransporten sowie die Entwicklung eines schlanken Wertstroms gleichermaßen adressiert.

Kurzfassung

Kundenspezifischere Produkte und kleinere Losgrößen zwingen kleine und mittelständische Unternehmen dazu, Produktionssysteme zu flexibilisieren. Hierzu ist es notwendig, neben den technologischen Anforderungen Mitarbeiterwissen in die Prozessplanung einzubinden. Videobasierte Tutorials stellen eine Möglichkeit dar, dieses Wissen zu externalisieren. Das Konzept einer videobasierten Prozessdokumentation auf Basis von Autorensystemen konnte bereits in die Produktion übertragen werden, bietet jedoch auch Potenziale, um Aufwände in indirekten Bereichen wie der Montageplanung zu reduzieren. In diesem Beitrag wird ein App-basiertes Konzept vorgestellt, welches auf Grundlage eines Autorensystems ein „Mitschreiben“ während des Aufbaus von Prototypen ermöglichen soll.

Implicit in the development of parallel programming language using Visual Basic
Authors: Al-naseri Zainab fahad mhawes
Published: June 2018

Several studies have been performed to investigate the benefits of parallel programming models, and compared the models with same language family. The parallel technique is applicable only when the programmer has a single computer with multiple processors to perform various tasks individually or the programmer number of different computers connected by a single network. Parallel programming model in computing is an idea of parallel computer architecture. This research introduced the concept of parallel programming models and languages. The present research mainly focused on the different parallel programming models proposed by previous researchers using distinct programming languages. Through analyzing the strengths and weaknesses of various programming models used for parallel computing, a new model is developed. Along with this, the concept of OOP (Object-oriented programming) in the context of parallel computing is also discussed. This research proposed a model named as Asynchronous Dynamic load Balancing (ADLB). ADLB model used MPI as avehicle for library implementation rather as an end-user programming system.

Published: June 2018

Data encrypting and steganography techniques each have its own merits and weaknesses. Crackers and hackers developed many software applications that can attack the weakness of these techniques and thus can reach to the meaning of the private information and its existence.

In this paper, a simple technique is proposed to make use of encrypting and steganography merits simultaneously, and thus makes any attempt for breaking both techniques at the same time harder than applying each of them alone. The proposal uses English, Arabic, or mixed writing plain text. Encrypting the text by AES-encrypting algorithm with an encryption key of 128 bit long and then hiding the encrypted text with only one part of the encrypting key (sender key only), in another English/Arabic (cover), plain text. The text hiding technique is done according to the nonprintable characters of the Unicode character set method. The proposed technique is coded into a form of Matlab program. Experimenting with this paper technique shows how difficult to break the system and thus can applying it in emailing private documents between users connected to a virtual network on an insecure public channel
Layered Graphs: Applications and Algorithms

Published: June 2018

The computation of distances between strings has applications in molecular biology, music theory and pattern recognition. One such measure, called short reversal distance, has applications in evolutionary distance computation. It has been shown that this problem can be reduced to the computation of a maximum independent set on the corresponding graph that is constructed from the given input strings. The constructed graphs primarily fall into a class that we call layered graphs. In a layered graph, each layer refers to a subgraph containing, at most, some k vertices. The inter-layer edges are restricted to the vertices in adjacent layers. We study the MIS, MVC, MDS, MCV and MCD problems on layered graphs where MIS computes the maximum independent set; MVC computes the minimum vertex cover; MDS computes the minimum dominating set; MCV computes the minimum connected vertex cover; and MCD computes the minimum connected dominating set. MIS, MVC and MDS run in polynomial time if k=Θ(log|V|). MCV and MCD run in polynomial time ifk=O((log|V|)α), where α<1. If k=Θ((log|V|)1+ϵ), for ϵ>0, then MIS, MVC and MDS run in quasi-polynomial time. If k=Θ(log|V|), then MCV and MCD run in quasi-polynomial time.
The Symplectic Camel and Poincaré Superrecurrence: Open Problems
Authors: Gosson Maurice A. de
Published: June 2018

Poincaré’s Recurrence Theorem implies that any isolated Hamiltonian system evolving in a bounded Universe returns infinitely many times arbitrarily close to its initial phase space configuration. We discuss this and related recurrence properties from the point of view of recent advances in symplectic topology which have not yet reached the Physics community. These properties are closely related to Emergent Quantum Mechanics since they belong to a twilight zone between classical (Hamiltonian) mechanics and its quantization.
Application of Dimensional Analysis to Project Laboratory Scale Numerical Modelling Prescribed Hydraulic Fracturing Results to Field Scales
Authors: He Qingyuan , Xu Jinhai , Oh Joung , Zhang Chengguo
Published: June 2018

Hydraulic fracturing has been applied in the cave mining industry with the purpose of re-creating an orebody rock mass condition that is suitable for caving. Prescribed hydraulic fracturing was proposed in a previous study as a supplement to the conventional hydraulic fracturing strategy. In this paper; dimensional analysis is used to project laboratory scale numerical modelling results to field scales in order to study the applicability of creating prescribed hydraulic fractures (PHFs) under field conditions. The results indicate that field scale PHFs are feasible if the stress shadows of the pre-located fractures are properly utilized. Water can be used to create the pre-located fractures that induce the local stress change in a low differential stress state; and the use of more proppants and a shorter pre-located fracture spacing lead to PHFs propagating more quickly towards the pre-located fractures. For field condition having high differential stresses, more viscous fluid must be used to create the pre-located fractures in order to enhance the stress shadows. In this case, a shorter pre-located fracture spacing does not necessarily result in the re-orientation of PHFs towards the pre-located fractures and may even lead to unsatisfactory pre-conditioning. A sufficiently high pre-located fracture net pressure to the differential stress ratio (close to 0.5) is the prerequisite for creating PHFs.
Solving Non-Smooth Optimal Power Flow Problems Using a Developed Grey Wolf Optimizer
Authors: Abdo Mostafa , Kamel Salah , Ebeed Mohamed , Yu Juan , Jurado Francisco
Published: June 2018

The optimal power flow (OPF) problem is a non-linear and non-smooth optimization problem. OPF problem is a complicated optimization problem, especially when considering the system constraints. This paper proposes a new enhanced version for the grey wolf optimization technique called Developed Grey Wolf Optimizer (DGWO) to solve the optimal power flow (OPF) problem by an efficient way. Although the GWO is an efficient technique, it may be prone to stagnate at local optima for some cases due to the insufficient diversity of wolves, hence the DGWO algorithm is proposed for improving the search capabilities of this optimizer. The DGWO is based on enhancing the exploration process by applying a random mutation to increase the diversity of population, while an exploitation process is enhanced by updating the position of populations in spiral path around the best solution. An adaptive operator is employed in DGWO to find a balance between the exploration and exploitation phases during the iterative process. The considered objective functions are quadratic fuel cost minimization, piecewise quadratic cost minimization, and quadratic fuel cost minimization considering the valve point effect.

This article presents an engineering study of an integrated system to produce bio-oil from microalgae biomass. The analysis is based on a pilot plant located at Minami-soma Fukushima, Japan, which further simulates 1 ha based-cultivation. Municipal wastewater and flue gases were utilized as nutrient sources for the microalgae culture of the proposed design. A flow sheet diagram of the integrated plant was synthesized by process engineering software to allow simulation of a continuous system. The design and sizing of the process equipment were performed to obtain a realistic estimation of possible production cost. The results demonstrated that nutrient savings was achieved by wastewater and CO2 utilization to the polyculture of native microalgae. Process simulation gave an estimated CO2 sequestration of 82.77 to 140.58 tons ha−1year−1 with 63 to 107 tons ha−1year−1 of potential biomass production. The integrated process significantly improved the energy balance and economics of biofuel production and also the wastewater treatment plant (WWTP). The economic analysis confirmed that higher biomass production and technology improvement were required to achieve operational feasibility and profitability of the current microalgae-based bio-oil production.

While intact forests have intrinsic value in terms of conserving biodiversity, they are also important for associated ecosystem services of soil and water conservation, in addition to the biodiversity, function and geomorphology of stream and river ecosystems. In this latter context, the perspective of watershed is more relevant than forest patch, however we are unaware of any landscape assessments of intact forested watersheds (IFWs). We mapped the coverage of forested watersheds with limited intervention for southern Patagonia (Chile, Argentina) using existing forest stand mapping and high resolution stream/watershed delineation (patch size ~ 0.4 km2). Validation and adjusted IFW boundaries was performed using high resolution satellite imagery for three major inland basins representing the north-south range of the study area. For both scales we evaluated size distribution, conservation status, forest type (deciduous vs. evergreen temperate forest) and bio-climatic zones (precipitation range 500 to >6000 mm/year). For the coarse regional analysis potential IFWs covered over 40% of land surface, and included nearly 60% of all forest cover. These figures were significantly reduced following basin scale validation to 6–21% for IFWs and 5–14% of forest contribution to IFW. IFWs identified in the regional analysis were lower elevation (0–100 m) due to abundant coastal drainages, whereas the basin analyses were higher elevation headwaters systems (1000+ m), the largest over 80 km2. Total IFW cover was estimated between 50,000–132,000 km2, the range a reflection of disparate results across these two scales, further highlighting the need for comprehensive revision and field validation. At the same time the difference in areas, defined mostly by minor levels of intervention, indicate the vast potential for management or restoration. Taken together they represent a nationally and globally significant contribution to of intact temperate forests and IFWs. Interactions between forest and stream ecosystems, and their implications for IFW conservation, are discussed in these contexts, based on examples from the region. Finally we used Getis-Ord Gi* statistics to identify hot and cold spots for different attributes, providing an example of a combined index for prioritizing IFW conservation.

To understand the relative importance of plant community composition and plant-induced soil properties on N transformations, the soil N mineralization, ammonification and nitrification characteristics of natural secondary forests (Quercus mongolica-Juglans mandshurica forest: QJF, and Quercus mongolica-Populus davidiana forest: QPF) and the adjacent larch plantations (Larix kaempferi forest: LF1 and LF2) were studied during the growing season. All of the forest types showed seasonal dynamics of N mineralization rates. The total cumulative N mineralization was significantly higher in QPF (73.51 kg hm−2) than in LF1 (65.64 kg hm−2) and LF2 (67.51 kg hm−2) (p < 0.05). The total cumulative nitrification from May to November was significantly higher in QJF (65.16 kg hm−2) and QPF (64.87 kg hm−2) than in LF1 (52.62 kg hm−2) and FL2 (54.17 kg hm−2) (p < 0.05). Based on the variation partitioning, independent soil properties were the primary determinants of the N transformations (13.5%). Independent climate conditions explained 5.6% of the variations, while plant variations explained 3.2% of the variations in N transformations. We concluded that different forest types with various plant community compositions have different influences on the litterfall quantity and quality and the nutrient availability, and these differences interact with seasonal climate conditions that in turn drive the differences in N mineralization.
A Political Genealogy of Dance: The Choreographing of Life and Images
Authors: Reid Julian
Published: June 2018

This article provides a genealogical critique of the history and modernity of dance. In doing so it establishes the political importance of dance as an art not principally of the body and its biopolitical capacities for movement, but of images and imagination. It traces the development of dance as an art of imagination, lost and buried in the works of Domenico da Piacenza, Jean-Georges Noverre, and Loïe Fuller, as well as its counter-movement expressed in the work of Rudolf Laban. It also locates contemporary dance within this political conflict by exploring new works, especially those of Ivana Müller, which call upon beholders to use their imaginations through the evocation of histories and memories. Such works can be understood to be deeply political, it will argue, because they work to transform society by creating time for a belief in the impossible. At its best, dance does not simply incite bodies to move but suspends movement, transforming the very image of what a body is capable of. These aims and practices of dance speak to contemporary concerns within political practice, theory, and philosophy for a reawakening of political imagination in times of crisis and neoliberal hegemony.
Role of Inosine–Uracil Base Pairs in the Canonical RNA Duplexes

Adenosine to inosine (A–I) editing is the most common modification of double-stranded RNA (dsRNA). This change is mediated by adenosine deaminases acting on RNA (ADARs) enzymes with a preference of U>A>C>G for 5′ neighbor and G>C=A>U or G>C>U=A for 3′ neighbor. A–I editing occurs most frequently in the non-coding regions containing repetitive elements such as ALUs. It leads to disruption of RNA duplex structure, which prevents induction of innate immune response. We employed standard and biased molecular dynamics (MD) simulations to analyze the behavior of RNA duplexes with single and tandem inosine–uracil (I–U) base pairs in different sequence context. Our analysis showed that the I–U pairs induce changes in base pair and base pair step parameters and have different dynamics when compared with standard canonical base pairs. In particular, the first I–U pair from tandem I–U/I–U systems exhibited increased dynamics depending on its neighboring 5′ base. We discovered that UII sequence, which is frequently edited, has lower flexibility compared with other sequences (AII, GII, CII), hence it only modestly disrupts dsRNA. This might indicate that the UAA motifs in ALUs do not have to be sufficiently effective in preventing immune signaling.

Aurone glycosides display a variety of biological activities. However, reports about glycosyltransferases (GTs) responsible for aurones glycosylation are limited. Here, the transcriptome-wide discovery and identification of an aurone glycosyltransferase with glycosidase activity is reported. Specifically, a complementary DNA (cDNA), designated as OsUGT1, was isolated from the plant Ornithogalum saundersiae based on transcriptome mining. Conserved domain (CD)-search speculated OsUGT1 as a flavonoid GT. Phylogenetically, OsUGT1 is clustered as the same phylogenetic group with a putative 5,6-dihydroxyindoline-2-carboxylic acid (cyclo-DOPA) 5-O-glucosyltransferase, suggesting OsUGT1 may be an aurone glycosyltransferase. The purified OsUGT1 was therefore used as a biocatalyst to incubate with the representative aurone sulfuretin. In vitro enzymatic analyses showed that OsUGT1 was able to catalyze sulfuretin to form corresponding monoglycosides, suggesting OsUGT1 was indeed an aurone glycosyltransferase. OsUGT1 was observed to be a flavonoid GT, specific for flavonoid substrates. Moreover, OsUGT1 was demonstrated to display transglucosylation activity, transferring glucosyl group to sulfuretin via o-Nitrophenyl-β-d-glucopyranoside (oNP-β-Glc)-dependent fashion. In addition, OsUGT1-catalyzed hydrolysis was observed. This multifunctionality of OcUGT1 will broaden the application of OcUGT1 in glycosylation of aurones and other flavonoids.
