    In the material strength test, stress and strain rate are often required to be constant. For example, during the cement quality inspection, the loading rate is required to be2.4 ± 0.2KN/S [1]; when measuring the upper and lower yielding points of metallic materials, the stain rate should stay between 0.00025/S and 0.0025/S; In the determination of elongation at break, the stress rate should stay in the range of 1-10N/mm2 S-1 when the elasticity modulus smaller than 150000 N/mm2 [2]. Since 1950s, Material Testing Machines, which adopted large-flow electro-hydraulic servo, valve to form control system, have appeared in developed countries. Control system of this type could meet the requirements for the stress and strain rate in the material strength test. For example, MTS and Instron from USA, Schench from German, and Shimadzu from Japan all adopted this type of system. With the improvement of the manufacturing level of proportional valve and the development of control technology, electro-hydraulic proportional valve began to be used as the main control part home and abroad [4]. However, this type of parts, which is vulnerable to pollution, requires medium of high cleanliness. It is of large noise and high price. This type of system could go wrong easily for the complex hydraulic system DOI: 10.17762/ijritcc2321-8169.15017

    Industrial Automation on the Specification of HT Capacitor

    Designing of capacitors has acquired so much attention in the development and recently different types of capacitors are also developed in the industry. Considering all the benefits such as power factor improvement, reduction of power losses, increasing efficiency so on. Capacitors are also used to raise the quality of supply and safe handling of power equipments. The main objective of this paper is focused on the design process of the power capacitor and different parameter of the capacitor. In the design process of the capacitor, parameters are considered namely microfarad rating of capacitor, Loss angle (tan delta), and temperature of capacitor. All these parameter are measured manually by the operator in the industry and this is sponsored by Sharada Electronics Pvt Ltd, MIDC Miraj. Most of the power system fails if there is any damage of capacitor so this system is designed in such a way that it measures all parameter automatically and send it to the control room to avoid the faults that are ignored by the operator.

    Up-gradation of Conventional Control Panel with PLC for the Total Utilization of Machine

    In the beginning of industrial revolution, especially in 1960 to 1970, automated machines wear controlled by electromechanical relays. These relays wear hardwired together inside the control panel. Many of the times the control panel was so huge that it would cover entire wall. Every connection in the relay logic must be connected. Wiring is not always perfect; it takes time to troubleshoot the system. This is very time consuming Process. On top of that the relays have limited contacts. If modification is required, the machine has to be stopped, the space may not be available and wiring has to be traced again to accommodate changes. The control panel can only be used for the particular process. It cannot be changed immediately to a new system. It has to be redone. In terms of maintenance, an electrician must be well trained and skilful in troubleshooting the control system. In short, the conventional relay control panel is very inflexible.

    Upgradation of Manual Magnetic Core Drill Machine

    Get PDF
    This paper deals with the upgradation of existing manual core drill machine. The existing manual core drill machine requires a labor operator every time to drill the hole till the drilling gets completed. So more time is required and accuracy is reduced. So the main aim is to make core drill machine fully automatic. So the automatic part can be developed by developing some of the part related to current sensing and controlling, depth sensing using encoder, no load position sensing , enrolling the required depth through the keypad and operating it with the stepper motor

    Implementation of Excel Parser for Web Integration of Digital Evaluation System of CSIBER

    Digitization and advancements in web technology have facilitated quick access to accurate data irrespective of its location and time zone. Time span becomes crucial in such cases since the data soon becomes stale. Further, web hosts data in variety of formats and sizes. Integrity, authenticity and confidentiality play a key role in data access. The main motto of web data accessibility is that data should be made available only to the person who is authorized to access it. CSIBER has recently installed Digital Evaluation System (DES) for automating the routine tasks of examination department. However, currently the software lacks in web interface. To address this issue, in the current paper, the authors have designed and developed an Excel parser in PHP which acts as an interface between DES and CSIBER’s official website by enabling examinees a quick access to online mark statement. The parser is flexible enough to take care of minor differences in structures of Excel spreadsheets. The deployment folder structure is presented and different cases are explored

    IMAGE SEGMENTATION TECHNIQUES IN MEDICAL ANALYSIS “A BOON FOR DETECTION OF CANCER”: A REVIEW

    No full text
    mage processing and computer vision systems can enhance the diagnostic capability of physicians by reducing the time required and resulting in accurate diagnosis. This paper presents the review of resentpublished segmentation and classification techniques for detection of Brain Tumors using Magnetic Resonance Images, which is an open challenge in the field of medical science till date. We present the comparative study of a couple of algorithms based on the technique of segmentation, extraction and classification of the images. Initially we start with segmentation based on localindependent projection-based classification, followed by segmentation using adaptive clustering and Level set method comparing these with the result of computer-aided detection /diagnosis involving the process of pulsed coupled neural network for image segmentation, followed by discrete wavelet transforms for feature extraction and feed forward back propagation neural network for classificatio

    Notes for genera – Ascomycota

    No full text
    Knowledge of the relationships and thus the classification of fungi, has developed rapidly with increasingly widespread use of molecular techniques, over the past 10--15 years, and continues to accelerate. Several genera have been found to be polyphyletic, and their generic concepts have subsequently been emended. New names have thus been introduced for species which are phylogenetically distinct from the type species of particular genera. The ending of the separate naming of morphs of the same species in 2011, has also caused changes in fungal generic names. In order to facilitate access to all important changes, it was desirable to compile these in a single document. The present article provides a list of generic names of Ascomycota (approximately 6500 accepted names published to the end of 2016), including those which are lichen-forming. Notes and summaries of the changes since the last edition of `Ainsworth Bisby's Dictionary of the Fungi' in 2008 are provided. The notes include the number of accepted species, classification, type species (with location of the type material), culture availability, life-styles, distribution, and selected publications that have appeared since 2008. This work is intended to provide the foundation for updating the ascomycete component of the ``Without prejudice list of generic names of Fungi'' published in 2013, which will be developed into a list of protected generic names. This will be subjected to the XIXth International Botanical Congress in Shenzhen in July 2017 agreeing to a modification in the rules relating to protected lists, and scrutiny by procedures determined by the Nomenclature Committee for Fungi (NCF). The previously invalidly published generic names Barriopsis, Collophora (as Collophorina), Cryomyces, Dematiopleospora, Heterospora (as Heterosporicola), Lithophila, Palmomyces (as Palmaria) and Saxomyces are validated, as are two previously invalid family names, Bartaliniaceae and Wiesneriomycetaceae. Four species of Lalaria, which were invalidly published are transferred to Taphrina and validated as new combinations. Catenomycopsis Tibell Constant. is reduced under Chaenothecopsis Vain., while Dichomera Cooke is reduced under Botryosphaeria Ces. De Not. (Art. 59)
