Inverse Creep

Creep and Inverse creep are the important fundamental properties of textile materials. These properties determine the relaxation behavior of the product. We have designed and fabricated an instrument which can measure the creep and inverse creep. The instrument consists of a Trans - Receiver unit interfaced with Embedded System along with the Personal Computer. Existing technique for measuring inverse creep does not measure the instantaneous extension or contraction. The newly fabricated instrument, can measure the instantaneous extension and contraction of the yarn of an accuracy of 0.02%. This can be measured after every 500 µs. The position of the yarn, which is to be hanged, is vertical. The ‘Electronic Timer Unit’, replaces a meter scale. Set up is improved by using electronic utilities. The capability is enhanced to next level of time and distance resolutions. Automation enables to have flexibility of time from microseconds to minutes. Data is stored in different text files. Different samples of Nylon multifilament yarn were used in the experiment. The length and the load were altered. Change in stress lead to instantaneous extension or contraction followed by creep or inverse creep. This can sensed by the sensor and further stored in the memory of the Computer. The percentage creep and inverse creep were measured and have been reported in this present paper. Your paper should be in the same format as this file. The abstract goes here. Your abstract should be a maximum of 200 words here clearly outlining the contribution of your paper. Abstract is in italic fonts.

The instrument consists of a Trans - Receiver unit interfaced with Embedded System along with the Personal Computer. Existing technique for measuring inverse creep does not measure the instantaneous extension or contraction. The newly fabricated instrument, can measure the instantaneous extension and contraction of the yarn up to an accuracy of 0.02%. This can be measured after every 500 µs. The position of the yarn, which is to be hanged, is vertical. The ‘Electronic Timer Unit’, replaces a meter scale. Set up is improved by using electronic utilities. The capability is enhanced to next level of time and distance resolutions. Automation enables to have flexibility of time from microseconds to minutes. Data is stored in different text files.

From decades Creep has been known and studied for textile materials. In comparison, a newly observed phenomenon of inverse creep seems not to have received much attention. A new instrument has been fabricated to measure creep and inverse creep in textile materials particularly yarns. Creep and Inverse creep measurements of few of the textile yarns like nylon multifilament yarn, Polyester multifilament yarn, Cotton and wool yarn at different levels of stress have been studied, using the new instrument along with Transreceiver, embedded system and Personal computer the automation is achieved and results are reported in the present paper.

AbstractWe show how loud-speakers, home digital recorders, and a common personal computer can be used to emulate VLBI observations on a small scale. These audio-VLBI observations allow for single-field astrometry (sources within the same interferometric field), differential group-delay astrometry, etc. These experiments can be set up very easily and in many possible configurations. Students may find these experiments very useful to learn about the innermost details of the interferometric technique.

Abstract The results of shielding effectiveness (SE) measurements of textile materials containing metal by the free-space transmission technique (FSTT) in the 1-26.5 GHz frequency range are presented in the paper. It is shown that experimental data processing using time-domain gating (TDG) makes it possible to effectively remove diffracted and reflected components from the desired signal. The comparison with the results obtained by other techniques, namely modified FSTT with TDG and coaxial line probe technique (ASTM D4935-99) is given. The comparison shows that the proposed technique gives more reasonable results while the measurement set-up is simpler in realization.

Human life saving is taking prominent role in the society, Unfortunately some of people meet accident every day at any time in various incidents. Here the accident happen due to flash flood which is rapidly changing in a river, leads to ultimate damages to the people lives and their properties at most of time in perilous locations like waterfall, River bridge and residing areas, which are in the vicinity of the river. Predominantly the people are gathering to visit the waterfall across the river and peripatetic on the riverbank or inside the river during slow water flow, some times it leads to fatality of people who are inside the river due to flash flood, since it can't be predictable in earlier. The proposed system is providing a solution to save the people lives under this kind of circumstances. The system has transmitting processor unit must be installed at least minimum of certain kilometers away from the perilous location to which the information about the flash flood parameters like flood velocity, volume metric flow, flood level rise per unit time and time consumption to arrive remote location for making awareness among the people peripatetic in side or any hazardous zone of the river. Here the big foot sensor working under ultrasonic principle is suggested to measure the above flood parameter and send to the Transmitting processor unit, which estimates the arrival time by the flood to reach the remote risky location. The processed data send to the receiver unit located at remote perilous location for making early sound and visualization alert of flood parameters on the large size screen. So that the people acquire adequate time to reach safe zone. The Transmitting processor unit starts to send this information to the receiver unit installed on both side of riverbank, if the flash flood parameter crosses the dangerous level. The sound volume is programmed to be changed gradually according to the rate of flood parameters.

This paper presents a protocol to support hard real-time traffic of end-to-end communication over non real-time LAN technology. The network is set up with nodes and switches, and real-time communication is handled by software (protocol) added between the Ethernet protocols and the TCP/IP suite. The proposed protocol establishes a virtual circuit based on admission control and manages hard real-time traffic to bypass the TCP/IP stack. This makes considerably reduce the dwell time in the nodes, and increase the achievable data frame rate. After the bypassing, traffic schedule is performed according to dynamic-priority EDF algorithm. The work does not need any modifications in the Ethernet hardware and coexists with TCP/IP suites, and then the LAN with the protocol can be connected to any existing Ethernet networks. It can be adopted in industrial hard real-time applications such as embedded systems, distributed control systems, parallel signal processing and robotics. We have performed some experiments to evaluate the protocol. Compared to some conventional hard real-time network protocols, the proposed one has better real-time performances and meets the requirements of reliability for hard real-time systems.
