The large memory requirement becomes the challenge for the NGS technologies, as the memory is the bottleneck for every application. There is need to reduce the memory utilization for the de Bruijn graph, so as to it could fit in low memory space. This work provides the efficient memory utilization for the de Bruijn graph. The minimizer breaks the reads into numerous little partitions with the goal that every partition could be loaded into main memory one by one; they process separately then later on merge to form the simple path of de Bruijn graph. This reduces the space usage required during construction of de Bruijn graph.
大内存需求成为NGS技术面临的挑战,因为内存是每个应用程序的瓶颈。需要降低de Bruijn图的内存利用率,使其能够适应低内存空间。这项工作为de Bruijn图提供了有效的内存利用。最小化器将读操作分成许多小分区,目的是每个分区都可以一个接一个地加载到主存中;它们分别处理,然后合并形成简单的德布鲁因图路径。这减少了构建德布鲁因图时所需的空间使用。

The paper discusses about the wind tree turbine which is a type of vertical axis wind turbine Savonius model. The turbine will be attached to a manufactured tree that will be installed in and around any public area such as parks, roads, public facilities, or business offices. The initial phase discusses about the theoretical evaluation of available wind power for a single aeroleaf wind tree turbine. The second phase evaluates the pressure drop across the aeroleaf blade at the various velocity using CFD simulation. The simulation outcome shows that, pressure drop is directly proportional to the wind velocity which causes rise in the power generated at the shaft. The less pressure drop is produced up to some radius of the aeroleaf and increases as the radius of aeroleaf increased. In third phase of experiment work, design a new single aeroleaf for wind tree turbine to measure actual shaft power at different wind inlet velocity. Experiment performance conducted on a single aeroleaf at different input wind velocities to measure the aeroleaf, entire casing and overall efficiencies. The result shows that power co-efficient increases at beginning and highest reaches at 32% at inlet velocity of 19 m/s.
本文讨论了树式风力机,它是垂直轴风力机的一种。涡轮机将被安装在人造树上,安装在公园、道路、公共设施或商业办公室等任何公共区域内或周围。初始阶段讨论了单叶式风力机可用风力的理论评估。第二阶段利用CFD模拟计算不同速度下叶片的压降。仿真结果表明,压降与风速成正比关系,风速使轴处发电功率增大。在气叶半径范围内产生较小的压降,并随着气叶半径的增大而增大。在第三阶段的实验工作中,设计了一种新型的单风叶,用于测量不同进风口速度下的实际轴功率。在不同输入风速下对单个气叶进行实验性能,测量气叶、整个机匣和整体效率。结果表明:进气速度为19 m/s时,功率系数开始增大,最高可达32%;

In this research work, performance and emissions of Tyre Pyrolysis Oil (TPO) in a diesel engine are experimentally examined as per Indian Standard: 10000. The main objective of this research work is to find the best proportion of blend based on performance and emission analysis. For the study, Tyre Pyrolysis Oil is added to diesel fuel, numbered D100 (pure diesel), D95T5 (by volume of 5% TPO and 95% diesel), D90T10 (by volume of 10% TPO and 90% diesel), D85T15 (by volume of 15% TPO and 85% diesel), D80T20 (by volume of 20% TPO and 80% diesel) and D75T25 (by volume of 25% TPO and 75% diesel). Fuels are tested in four strokes, single cylinder, direct injection, water cooled diesel engine. The effect of various blends on Mechanical Efficiency, Specific Fuel Consumption (SFC) and Thermal Efficiency are investigated by the performance test. The influences of blends on CO, O2, NOx, CO2 and HC are investigated by an emission test using the 5-gas analyzer. The investigation shows that D85T15 blend has been proved best based on performance test compared to other blends. The investigation of Emission analysis shows that D85T15 blend has better combustion characteristics compared to others.

To mitigate climate change and environmental protection industries have been putting emphasis on reduction in carbon dioxide (CO2) emissions. The transportation industry is one of the largest contributor of greenhouse gas (GHG) emissions. The European Union has set targets of 20% reduction in GHG by 2020 compared with 1990 levels. In order to meet the rigorous requirements for more desirable fuel efficiency and emission control, there is an emerging trend to deploy Al and Mg alloys in place of usual steels and cast irons in automobiles. These materials (Al and Mg) are however, more expensive than the steels and cast irons. Cast aluminium and magnesium components compared with cast irons and steel are potentially less expensive to produce because of their ease of machining and reduced manufacturing cycle times. Wrought aluminium and magnesium components as compared with their ferrous counterparts are more expensive to produce. This article compares the uses of aluminium and magnesium alloys as substitutes for steels, cast irons for applications in the automotive industry.
为了减缓气候变化和环境保护行业一直把重点放在减少二氧化碳(CO2)排放上。交通运输业是温室气体(GHG)排放的最大贡献者之一。欧盟已经设定了到2020年温室气体排放量比1990年减少20%的目标。为了满足更理想的燃油效率和排放控制的严格要求,在汽车上使用铝和镁合金代替通常的钢和铸铁是一种新兴的趋势。然而,这些材料(铝和镁)比钢和铸铁更昂贵。与铸铁和钢相比,铸铝和镁部件的生产成本可能更低,因为它们易于加工并缩短了制造周期。锻造铝和镁的部件与铁的同类产品相比,生产成本更高。本文比较了铝和镁合金作为钢、铸铁的替代品在汽车工业中的应用。

The green novel catalyst 1-[(4-nitrophenyl) methyl]-4-(pyridin-2-yl)piperazine (NMPP) polymer composite was synthesized by condensation polymerization. The polymer composite was characterized by Fourier transform infrared (FTIR), and high resolution scanning electron microscope (HR-SEM). The inhibition action of the polymer composite was investigated by conventional weight loss method, and electrochemical impedance spectroscopy (EIS). The maximum corrosion inhibition efficiency of 88.34% was obtained at concentration level of 6% at 303 K. The results revealed NMPP as a mixed type corrosion inhibitor, the thermodynamic and kinetic parameters also revealed adsorption of catalyst on to mild surface as exothermic and the adsorption was confirmed by conventional weight loss method. The morphology of mild steel coupons was investigated by HR-SEM. The HR-SEM results showed novel catalyst to have inhibited corrosion on mild steel in 1 M HCL on CO2 environment.

This paper presents the stress patterns and deformation in an artery with an aneurysm under a variation of pressure. An aneurysm occurs when a weak portion of artery wall bulges out under pressure. To make a proper treatment decision, one must understand the formation and growth of the condition. In this article, finite element analysis of the formation of fusiform aneurysms in arteries is presented using the hyperelastic material model by employing ANSYS. We present the effect of different blood pressures in the deformation of the weakened arterial wall and also compare it with a normal artery. This work can be used as a reference for research in this area.

Appurva Jain, Anshuman Mishra
The application of the Elasto plastic-damage model is used to describe the ductile fracture model. Few parameters are responsible for ductile damage and its mechanism can be revealed by using Elasto plastic models. An overview of different models is described in this paper. Parameters responsible for high-stress triaxiality and low-stress triaxiality are also described in this paper. The objective of this article is to provide a review of Elasto-plastic damage models, which can be used for prediction of ductile fracture. Stress triaxiality is the ratio between mean stress and equivalent vonmisses stress.
采用弹塑性损伤模型来描述延性断裂模型。影响塑性损伤的参数很少,弹塑性模型可以揭示塑性损伤的机理。本文概述了不同的模型。本文还描述了高应力三轴性和低应力三轴性的参数。本文综述了用于预测韧性断裂的弹塑性损伤模型的研究进展。应力三轴性是指平均应力与等效应力的比值。

India is facing multiple problems regarding taxation as tax evasion, black marketing, high price charge and corruption. Meanwhile indirect taxes paid by the producing firms are collected on level may be or may not be timely and honestly deposited to the department. There is a big issue of multiple tax system and the complex procedure. To get rid of these problems, a uniform tax system named as Goods and Service Tax (GST) was introduced. The current article is proposed to measure the effectiveness of GST as well as tries to analysis the effect of GST on Indian economic system especially in inflation rate and on foreign trade. Some suggestions are also proposed for make more effective system in India.
印度在税收方面面临多重问题,如逃税、黑市、高价收费和腐败。同时,生产企业所缴纳的间接税是按等级征收的,可能会或可能不会及时、诚实地交存到部门。多重税制和复杂的程序是一个大问题。为了解决这些问题,一种统一的税收制度被称为商品和服务税(GST)。本文旨在衡量商品及服务税的有效性,并试图分析商品及服务税对印度经济体系的影响,特别是对通货膨胀率和对外贸易的影响。为印度建立更有效的制度,提出了一些建议。
