Nanofluids made by mixing the nanoparticles with the cutting fluid can be applied in the machining process to reduce the tool wear and the surface roughness. The Taguchi method based on the grey relational analysis theory was selected to optimize multi-responses for the groove milling process using nanofluids as the tool wear and the surface roughness. The grey relational index (GRI) were determined from the experimental results (the tool wear and the surface roughness) by using the grey relational analysis theory. Then the optimal condition – (the nanoparticle concentration 0.2% and the cutting speed 25mpm) was determined by Taguchi’s method through the mean value and ratio (S/N)..

The paper aims to present the design of a multipurpose machine that can do three operations namely dehusking, cutting and grating the coconut. In order to dehusk the coconut, the procedure is to have the coconut fixed between the toothed shaft containing spikes and incorporate the opposite movement to it. After the removal of the husk, coconut is removed out which is then sent for the cutting process, which has the provision of punch also, if the coconut water is desirable. The final process is the grating of the coconut with the help grating tool which has notches on its periphery. The model would be beneficial for the industries where the raw material is coconut.
本文的目的是设计一种能进行椰壳脱壳、切壳、磨碎三种工序的多功能机。为了剥去椰子的壳,步骤是将椰子固定在含有尖刺的齿状轴之间,并将相反的运动与之结合。在去除外壳后,椰子被取出,然后送到切割过程中,如果需要椰子水,也可以提供冲床。最后的过程是用边缘有切口的辅助光栅工具对椰子进行光栅。这种模式将有利于以椰子为原料的行业。

This paper aims to present a model of a machine that can perform multiple operations on wood which is efficient and reliable than machines that already exist. The paper can help the common man, the daily worker, the carpenter that toils away by providing him with a tool at his disposal that can save his time, money and labor. The multipurpose wood working machine is unique in the manner that it utilizes a single multi-point tool to conduct all its operations and is operated by a single motor to save energy. The multipoint tool not only replaces multiple other tools but also saves energy by utilizing a single motor as compared to multiple motors which would be required if there were multiple tools. This also decreases the area the machine will take up making it more portable and lighter. By utilizing a single tool, there is an increase in the safety of the machine, as multiple tools mean multiple hazards. The tool will function in a manner similar to a routing machine. It is fixed in a module which holds it perpendicular to the vice which will be holding the work piece. The tool can transverse in all three directions using sleeves which are wrapped around threaded rods. Actuator motors then inhibit motion in all 3 dimensions using a control board. By doing so, the multipoint tool can work to its full potential and perform various multiple operations such as cutting, planning, drilling and slotting.
本文旨在展示一种机器模型,它可以对木材进行多种操作,比现有的机器更高效、更可靠。纸可以帮助普通人、日常工作者、辛勤工作的木匠,为他们提供一种工具,可以节省他们的时间、金钱和劳动力。多用途木工机床的独特之处在于,它利用一个多点工具来进行所有的操作,并由一个电机操作,以节省能源。多点工具不仅取代了多个其他工具,而且与使用多个工具时需要多个电机相比,使用单个电机可以节省能源。这也减少了机器占用的面积,使其更轻便。通过使用单一工具,增加了机器的安全性,因为多个工具意味着多个危险。该工具将以类似于路由机的方式运行。它被固定在一个模块中,这个模块使它与夹住工件的副钳垂直。该工具可以在所有三个方向上横向使用套筒,套筒缠绕在螺纹杆上。执行器电机然后抑制运动在所有3个维度使用控制板。通过这样做,多点工具可以充分发挥其潜力,并执行各种多种操作,如切削、规划、钻井和开槽。

Gesture controlled vehicle is a type of robot which can operated by human hand movements. The user needs to wear a glove which consists of transmitter and sensors like IR sensor. These sensors help in recording the movement of hand in a desired direction which ultimately results in the motion of robot or vehicle. It will be very easy for user to interact with car or robot more easily due to wire free connectivity. Vehicle can be controlled with the help of accelerometer sensor which is connected to hand glove. This will help the applicant to control the forward, backward and sideways movements. We have made the cross connections of motors which will help in the movement of tyres so that vehicle can take a sharp turn without any difficulty. Hand gesture controlled driverless vehicle is developed with the help of Arduino Nano, three-axis accelerometer, RF transmitter and receiver module..

Using the “Lean Concept” to Improve Contract Procurement Processes of Service Utility Companies 运用“精益理念”改进服务公用事业公司合同采购流程
Pub Date : 2019-03-31 DOI: 10.46593/ijaera.2019.v04i11.002

Annually, a service utility company in the Kingdom of Saudi Arabia processes thousands of contracts for bidding. These contracts will in turn generate projects to maintain the quality and consistency of the generation, transmitting and distribution of electricity to the company’s consumers. The service utility company’s Contracting Department is responsible for the process of bidding for these contracts. Contracts subject to bidding must be signed in less than 175 days from the date of approval to allow adequate time for the implementation of the company’s maintenance and operational goals. However, at present, this conditional time allowance is rarely met. Hence, to improve the current situation, the “Lean Concept” is now applied and has resulted in a vast improvement in the contracting process. Contract cycle time has improved, waste has been eliminated and defects have been minimized. Improved cycle time of the contracting process has marked an increase in client satisfaction as a result of the finalization of contract signings in a shorter period in addition to a subsequent increase in the achievement of customer (utility user) satisfaction. The standard period for contracts signed-out has been reduced from 58.87% to 10.34%, and the sigma level process has jumped from -0.23 to 1.26.
每年,沙特阿拉伯王国的一家服务公用事业公司要处理数千份招标合同。这些合同将反过来产生项目,以保持发电、输电和分配给公司消费者的电力的质量和一致性。服务公用事业公司的承包部门负责这些合同的投标过程。招标合同必须在批准之日起175天内签署,以便有足够的时间实施公司的维护和运营目标。然而,目前,这种有条件的时间允许很少得到满足。因此,为了改善目前的状况,现在应用了“精益概念”,并在承包过程中产生了巨大的改进。改善了合同周期,消除了浪费,最大限度地减少了缺陷。承包过程周期时间的缩短标志着客户满意度的提高,因为在较短的时间内完成了合同的签署,此外还增加了客户(公用事业用户)满意度的实现。合同签订的标准期限从58.87%降至10.34%,sigma水平流程从-0.23跃升至1.26。

This work reports on a theoretical investigation of superlattices based on Cd1-xZnxS quantum dots embedded in an insulating material. These structures, assumed to a series of flattened cylindrical quantum dots with a finite barrier at the boundary, are studied using the Kronig – Penney method when the well width depends on the superlattice period. The fundamental miniband has been computed, for electrons, as a function of zinc composition for different inter-quantum dot separations. As is found, the fundamental miniband width decreases with the zinc composition and the superlattice period separately. Moreover, this study is of a great interest for designing novel nano devices, particularly, the nonvolatile memories.
本文报道了基于Cd1-xZnxS量子点嵌入绝缘材料的超晶格的理论研究。当阱宽取决于超晶格周期时,我们用Kronig - Penney方法研究了这些结构,假设它们是一系列在边界处具有有限势垒的扁平圆柱形量子点。对于不同的量子点间分离,计算了电子的基本微带作为锌成分的函数。结果表明,微基带宽度分别随锌的组成和超晶格周期而减小。此外,本研究对设计新型纳米器件,特别是非易失性存储器具有重要意义。

Corrosion is an often-used term regarding the ferrous metals also the general phenomenon of the formation of metal oxides, sulfides, hydroxides or any certain compound on the metal surface itself. There were found the effect of corrosive compounds in crude oils on the metallic corrosion in most of researches up to certain stage. In the current research it was expected to speculate the effect of sulfur, mercaptans, organic acids and salts in both Murban and Das Blend crude oils on the corrosion rates of seven different types of ferrous metals and variations of the hardness of such metals. The corrosive properties of both crude oils were determined by the standard methods and instruments. The chemical compositions of metals were detected by XRF detector. A batch of similar sized metal coupons was prepared, and those metal coupons were immersed in both crude oils separately. The rates of corrosion of those metal coupons were determined by the weight loss method after 15, 30 and 45 days from the immersion also both initial hardness and hardness after corroded of each metal coupon were tested by Vicker’s hardness tester. The corroded surfaces were observed by the optical microscope also the ferrous concentration and copper concentration of each crude oil sample were measured by the atomic absorption spectroscopy (AAS) after exposed to metals. There were found relatively lower corrosion rates from stainless steels than other metals, higher corrosion rates of four types of metals in Murban crude oil although it was composed lower amount of sulfur, mercaptans, organic acids and higher amount of salts than Das Blend, higher ferrous concentrations in crude oil samples which were exposed to carbon steels than other crude oil samples whereas high concentrations of copper in crude oil samples relevant to the Monel metal and eventually it was a slight reduction of the initial hardness of each metal coupon due to the corrosion.
腐蚀是一个关于黑色金属的常用术语,也是金属氧化物、硫化物、氢氧化物或任何某种化合物在金属表面本身形成的一般现象。到一定阶段,大多数研究都发现了原油中腐蚀性化合物对金属腐蚀的影响。在目前的研究中,预计将推测Murban和Das Blend原油中的硫、硫醇、有机酸和盐对七种不同类型的黑色金属的腐蚀速率和这些金属硬度变化的影响。采用标准方法和仪器测定了两种原油的腐蚀性能。用XRF检测器检测了金属的化学成分。制备了一批尺寸相近的金属券,分别浸入两种原油中。分别在浸泡15、30、45天后用失重法测定各金属片的腐蚀速率,并用维氏硬度计测定各金属片的初始硬度和腐蚀后硬度。用光学显微镜观察腐蚀表面,并用原子吸收光谱(AAS)测定各原油样品在金属作用下的铁离子浓度和铜离子浓度。不锈钢的腐蚀速率比其他金属低,Murban原油中的四种金属的腐蚀速率更高,尽管它的硫、硫醇、有机酸和盐的含量比Das Blend低。与其他原油样品相比,与碳钢接触的原油样品中铁的浓度较高,而原油样品中铜的浓度较高与蒙乃尔金属有关,最终由于腐蚀导致每种金属的初始硬度略有降低。
