  [Abstract] [PDF] [Cite]

Abstract:

The paper presents the transmission of vibrations through the steering wheel of the tractor during the ploughing field. The measurements of vibration were carried out on the tractor randomly chosen. An investigation was conducted to determine the transmission of vibration from the steering wheel of the tractor to the wrists and upper arms of the operator under actual field conditions during ploughing field. The vibrations transmitted through the steering wheel of the tractor to the hand of the operator was measured and the frequency spectra for the chosen working conditions were obtained. The maximum transmissibility of vibration were observed in the first two frequency interval (in Hz) i.e. 1-20 and 20-40. The vibration, which is transmitted from the steering wheel of the tractor to the wrists, arms and shoulders causes discomfort to the operator and results in early fatigue.

• Compressive Sensing in Speech from LPC using Gradient Projection for Sparse Reconstruction
  Viral Modha, Ravi Butani, Ankur Undhad
  [Abstract] [PDF] [Cite]

Abstract:

This paper presents compressive sensing technique used for speech reconstruction using linear predictive coding because the speech is more sparse in LPC. DCT of a speech is taken and the DCT points of sparse speech are thrown away arbitrarily. This is achieved by making some point in DCT domain to be zero by multiplying with mask functions. From the incomplete points in DCT domain, the original speech is reconstructed using compressive sensing and the tool used is Gradient Projection for Sparse Reconstruction. The performance of the result is compared with direct IDCT subjectively. The experiment is done and it is observed that the performance is better for compressive sensing than the DCT.
Index Terms: Compressive sensing, LPC, GPSR.

  Mohammad Javad Erfani and Fatemeh Nosrati
  [Abstract] [PDF] [Cite]

Abstract:

Ali Esfandyari whose penname is Nima Yushij has created a significant change in Persian poetry by composing poetry and propounding his literary theories., in such a way that all of the contemporary poetic trends and all of the famous poets in this area are among his followers, imitators, or the poets whom are influenced by Nima's poetry and theories. Modern lyric poetry is considered as one of the important trends of the contemporary poetry the emergence and propagation of which is indebted to Nima's Afsaneh Verse Collection. Afsaneh does not deny all of the components of classic poetry, but corrects or completes some of its aspects. The poet's change of attitude and view about being and love, employing dramatic elements and novel words, as well as exploiting natural elements for expressing internal and mental moods of characters are among the most important components to which the new lyric poets paid attention. In the present study, the characteristics of Afsaneh, the effective aspects of this collection on modern lyric poetry and the components of this trend have been studied.
Keywords Nima Yushij, Afsaneh, Modern Lyric Poetry, Semi-Classical Poetry.

  [Abstract] [PDF] [Cite]

Abstract:

Nowadays, natural fibers are used as reinforcement in composite materials. The Alfa fibers have undergone an alkaline treatment with sodium hydroxide NaOH at a concentration of 10%, during an immersion period of two days. After drying, the Fourier transform infrared spectroscopy by attenuated total reflection (FTIR-ATR) and X-ray diffraction (XRD) were used for the analysis of the chemical properties of these fibers which were extracted from the plant Alfa of the region Al Haouz (Morocco) in order to study the modifications resulting from the alkaline treatment. The results proved the presence of the cellulose, with an increase in its proportion in those fibers which have undergone an alkaline treatment with NaOH, the presence of lignin and pectin, as well as their disappearance after the alkaline extraction.
Keywords: Alfa (Esparto grass), cellulose, composite materials, extraction, Natural fibers.

  Ravindra J. Makwana, Maheshkumar V. Makwana, Biraju J. Trivedi, Hitesh C. Patel
  [Abstract] [PDF] [Cite]

Abstract:

Vehicular Ad hoc Networks [VANET] is one of the fastest emerging technologies for research as there are many issues and challenges to be addressed by the researchers before the technology becomes commercialized. Vehicular communication systems developed largely by the growing interest in intelligent transportation systems [ITS]. Cooperative driving can improve safety and efficiency by enabling vehicles to exchange emergency messages to each other in the neighborhood and to assist driver in making proper decision to avoid vehicle collisions and congestion. Broadcast transmission is usually used for disseminating safety related information among vehicles. Message Broadcast over wireless networks poses many challenges due to link unreliability, hidden terminal, message redundancy, and broadcast storm, etc., which greatly degrade the network performance. In most of the emergency situations, there is less time to make a handshake with other nodes in the networks, as the emergency message is to be delivered fast and efficient. Broadcasting information is usually very costly and without limiting techniques this will result in serious data redundancy, contention and collisions. This work focuses on Broadcasting Scheme for Message Dissemination.
Keywords: Broadcast Storm, intelligent transportation systems [ITS], Message Dissemination, Redundancy.
