Studies on ore mineralogy of placer ilmenite from parts of east coast of India

Abstract Placer ilmenites from three deposits of Andhra Pradesh coast have been investigated for their ore mineralogy. The deposits studied are Kakinada, Bhimunipatnam, and Srikurmam. Standard ore mineralogical methodology adopted for the preparation of polished sections of placer ilmenite grains from the three deposits. The detailed study of these sections under reflected light microscope revealed that the ilmenites from Kakinada are devoid of exsolutions whereas the ilmenites from other two deposits have indicated exsolved phases in the grain level textures, these phases are mainly Ilmenau-hematite, hemo-ilmenite and exsolved phases of rutile. The grain level textures or exsolved phases observed are 1) Homogenous ilmenites, 2) Ilmenites with simple Exsolutions, 3) Ilmenites with complex Exsolutions, 4) Irregular forms, 5) Dispersion or emulsion texture, 6) Lamellar Texture, 7) Skeletal Texture, 8) Worm like lamellae 9) Myrmekitic or Graphic Exsolutions and, 10) Alteration textures. Their presence will have implications for the processing of ilmenites. Because of the fact that the hematite phases in the ilmenite grain will make the ilmenite more iron-rich and thus may result from some processing problems as well as reduced titanium recovery.

Microcontroller based seeding and plowing using sensor and Bluetooth technology

In the field of agriculture in India, seeding and plowing are the two important operations. In order to increase the agricultural yield, these two operations must be effectively carried out. Agriculture is a vast economic zone and plays an important role in the overall economic development of the nation. Technical advances in the field of agriculture determine the potential for some agricultural activities. In this paper, we have proposed a novel approach to smart farming by connecting smart sensitivity systems through wireless communications technology. At present, the technologies used for these two operations are not up to the mark. Therefore, an attempt is made in this project to suggest effective technical methods to improve the seeding and plowing operations. Agriculture is a major economic sector and plays an important role in the overall economic development of the nation. Technical advances in the field of agriculture determine the efficiency of some agricultural activities In this project Renesas 64 pin microcontroller is used, it is the main component of the project, it controllers all the operations performed by the machine. Bluetooth is used for communication purpose. When the machine start moving in forward direction, ultrasonic sensor detect the obstacle present in the path of the vehicle, and it start plowing with the help of DC motor, connected to the plow mechanism. Seed sowing is done with the help of solenoid valve. The names of two operations (seeding and plowing) is displayed on LCD. So that these machines reduce the human effort ensuring efficient utilization of resources.

Airport with a circular runway in India

In India, there are 26 international airport and 18 domestic airports. Indira Gandhi International airport in Delhi is the busiest airport in India with 63.5 million passengers in 2017. It is predicted to cross 80 million in 2018. It is the only airport to enter into the top 20 Asia busiest airport. There are three runways at IGI with flight movement from 76 to 96 per hour. India receives 122 million domestic and 47 million international passengers. Circular runway concept is the concept which had been in considerations for a long time. This concept offers a large number of facilities and new airport managing system. There is a runway which is constructed in form of the circle consisting of segments. This concept will be applied on the existing airports in India and feasibility will be determined. This will help in forming a new basis for construction of an airport. It is going to help the country both economically and financially. If feasible it will solve problems which are currently being faced in all over India like bad baggage handling at Chennai airport, flight delay due to the busy runway, the single airport in Delhi (Delhi being the large passenger junction) etc. The circular runway will provide high air traffic movement with more aircraft movement per hour. In this paper, we are going to design two Circular Runway for existing airport and check the feasibility of construction of the new runway in India.

A systematic review on online airline reservation system

As the innovation advancements are immediately created including mobile innovation, the web application for reservation services can upgrade people's life, make it less complex. This looks into presents a reservation system for airline organizations to rearrange the way toward booking a flight. The clients, as a rule, purchase their ticket manually furthermore, perhaps hold up in a line to check the required flight. In this paper, we presented a survey on airline reservation system. The proposed system executed to conquer manual system issue by making the booking from home or somewhere else and save time and effort.

Steel fiber reinforced concrete under cyclic loading: An overview

In recent years, it has been recognized that addition of small closely spaced and uniform dispersed discrete steel fibers in concrete substantially improve its static and dynamic properties. The addition of steel fibers from 0.5 to 2.0 percent by volume in concrete is found to impart superior strength characteristics i.e. compressive strength, flexural strength, shear strength, fatigue strength and impact resistance. Recently, the use of steel fibers has increased in flexural members and columns of concrete structures subjected to cyclic loadings such as bridge decks, highway roads, runways of airports, offshore platforms and buildings. It is necessary to obtain more information on the mechanical behaviour of steel fiber reinforced concrete under cyclic loading in attempting applications of SFRC in structural members. The present investigation was planned to study the plain and steel fiber reinforced concrete under cyclic loading. The basic parameters of the study were fiber contents expressed as volume fraction and stress levels expressed as a percentage of the maximum flexural strength. The fiber contents used were 0.5 and 1.0% by volume of concrete. The beams were tested at three stress levels i.e. 85%, 90%, and 95%. Straight mild steel fibers were used in the study with an aspect ratio of 70. The physical properties of the basic constituent material viz, cement, sand, coarse aggregate, steel fiber were obtained as per relevant Indian standard specification. The compressive strength of concrete was obtained at 28 days. The mix proportion used was 1: 1.52:1.88 by weight with a water-cement ratio of 0.47. In fresh state properties of SFRC, workability tests present were carried out with indicators of workability i.e, slump, compaction factor and inverted cone test. From the study, it was found that the addition of fibers to the concrete effects the cyclic loading life significantly under flexural cyclic loading. The variability in the cyclic loading life of specimen is quite large as expected in any cyclic loading test programme. The ultimate failure followed almost immediately after the first crack.

Improvement in production rate by reducing the defects of injection moulding by DMAIC approach

Six Sigma is a well-structured methodology that concentrates on decreasing variation, measuring defects and beneficent the quality of products, processes, and services. Six Sigma methodologies were primarily progressing by Motorola in the 1980s and it targeted a difficult aim of 3.4 parts per million defects. Six Sigma has been on an unbelievable run over 25 years, manufacture important savings to the under the most line of many large and small organizations. This work presents the step-by-step application of the Six Sigma (acquaint, Measure, Analysis, progress, and monitoring) approach to eliminate the defects in injection moulding process this has helped to decrease defects in the process and thereby progress productivity.
