New generalized equations (in 3-dimensions) are derived and proposed to perform numerical integration of various functions over an arbitrary domain in the actual/physical coordinate system. The arbitrary domain can be enclosed by linear planes, curved planes or combination of linear and curved planes. These generalized equations do not involve any symbolic manipulation to perform the numerical integration. The proposed numerical integration technique is validated through several examples. Later, the generalized equations are further extended to enable exact integration of trivariate monomials over a domain enclosed by linear planes or curved planes which can be described by simple polynomials. Simulation results showed that the proposed exact integration technique produces accurate results faster, as compared to analytical solution which implements fully symbolic manipulation.

Solar energy is avirtually unlimited source whose power on the earth’s surface is estimated at 20 KWh. This is more than 100 times higher than the predicted values of electric power required for the planet; use of this huge energy source is not associated with any environmental pollution. Today, in the face of increasing limitations onnot-reproducible energy resources, complexity appreciation of their production attaches great importance to the use of solar energy.Precast concrete industry is a major consumer of thermal energy, and the most energy-intensive technological conversion, which consumes more than 70% of energy, heat treatment products.Among the conditions used in the dry hot climate the heat treatment method of the concrete, the most rational method is solar thermal processing, whichin recent years has been developed and put into production as aneffective method of heat treatment of concrete products using solar energy in open workshops and polygons as solar thermal processing them using translucent insulating coatings, including helio-forma with heat storage elements—helio warming using special film-forming compositions. The variety of ways solar thermal processing provides optimal and economical choice for heating this type of design with minimal costs. Thus, our studies have shown that the use of solar energy is a promising method of heat treatment of concrete.Today, broad investigations, which would develop methods solar thermal processing develop new and facilitate their implementation in production. The technology of production of precast concrete by using Solar energy in Kazakhstan.

There are different ore deposits in central Alborz which are distributed from east to west. Except Emaft fluorite ore deposit, other ore deposits in upper and middle members of Elika formation are belonged to Triassic age and covered by Palan evaporated formation. The genesis of these deposits is considered as diagenetic to epigenetic. Fluorite reservoirs that filleld faults or karst zones (open space filling) are originated in epigenetic. Layers and lenses are supposed as digenetic or digenetic. From this fluorite a double polished thin section (polished wafers) was prepared and its salinity and homogenization temperature of fluid inclusion was tested using Linkham Tm 600 model. The results showed that in spite that the geographical distribution ore deposits, their density is the same in everywhere, but redeposit with digenetic or digenetic characteristic showed lower salinity. According to the salinity and homogenization temperature characteristics, these ore deposits are classified in Irish to MVT type.

This study reports on recent improvements made to a phoneme-matching algorithm (PMA) reported in a previous study. Similar to its predecessor, the purpose of the enhanced PMA (EPMA) is to identify word recognition errors in automatically generated transcripts detailing the speech content of digital multimedia soundtracks that are routinely queried by professional researchers (such as academics and archivists). In order to alert a user to the possibility that a particular search term may have been incorrectly recognised as some other word or phrase, the EPMA – when invoked during a query operation – will parse the transcript‟s text to locate words or phrases of similar phonetic structure to the query term and then present these suspected speech recognition errors to the user for consideration. The EPMA‟sperformance has been improved by incorporating techniques to learn from user feedback concerning error identification.When tested on a corpus of digital multimedia, the EPMA averaged an 80.55% success rate in correctly identifying words/phrases which were actually instances of misrecognised query terms.

The increasing use of smartphones and tablet computers as personal and business tools poses new levels of complexity to IT management and security.With continued growth of smartphones, and associated increase of mobile security concerns, users of mobile devices must be assured that the services they receive must be secured and trustworthy. A QR code (quick response code) is a type of 2D bar code that is used widely to provide easy access to information through a smartphone. It is envisioned that the technology of QR code could be applied for secured communications using smart phones.
This paper provides a design framework for sending encrypted message using QR code, and decrypting the received QR code. An application is developed using Apple’s iPhone to demonstrate how mobile devices such as smart phones can communicate securely with another device using QR code. The sending smartphone can encode encrypted data in a QR code, and receiving smart phone can then decrypt the data encoded in QR code and retrieve the information. User can choose different encryption/decryption algorithm such as AES for secured transmission of data.
The iOS SDK together with Xcode IDE is used for the design and development of the iPhone application. The design architecture is developed using Apple’s iOS mobile operating system, PHP server and MySQL database. The paper successfully demonstrates the feasibility of using QR code to securely transmit message between mobile users. The system works as expected, however rigorous analysis to assess the performance is deferred for future study.

Normally BaTiO3 has a high dielectric constant (1400-2200),but when it has been doped by SrTiO3with different compositions, then the dielectric constant of doped BaSrTiO3(BST) has become very low. Dielectric constant decreases almost exponentially with the increase of frequency. The Polarizability of BaSrTiO3 has been measured which is found very low. The values of polarizabilities have been found negligible and these values decreases very slightly with the decrease of dielectric constant. Doped sample showed a low loss factor. As the frequency increases, loss factor decreases for high frequency range. The resistivity of doped BaSrTiO3 has been measured that is found very high. So it may act as an insulator.

This paper presents a study of some physical properties of bamboo & bamboo-cotton(50:50) blended yarn fabrics which are commonly used for apparel production. Yarns of 4 different counts such as 20, 24, 30 & 40Ne were used as warp & Weft in bamboo & bamboo-cotton blended yarn fabric. All fabrics were produced in twill weave with 54 ppi. Various test such as breaking strength, elongation, fabric weight, thickness and abrasion resistance have been carried out to study the performance of bamboo & bamboo-cotton(50:50) blended yarn fabrics. The experimental results indicate that bamboo fabric exhibits higher breaking strength than bamboo-cotton (50:50) blended yarn fabric. The higher elongation values are noticed in the case of 100% bamboo fabric than bamboo-cotton (50:50) blended yarn fabrics. It is also found that bamboo-cotton (50:50) blended fabric exhibits higher tearing strength than 100% bamboo fabric of similar specifications. It is found that 100 % bamboo fabric exhibits better performance than bamboo-cotton (50:50) blended yarn fabrics.

Medicinal plants are a large group of plants that are used to prevent and or treat of human and animal diseases. The World Health Organization (WHO) estimates that 80 percent of the population of some Asian and African countries presently uses herbal medicine for some aspect of primary health care. Since migrating nomads have more connection with nature and on many days of the year they are far from the cities, therefore they take medicinal plants more than other people. By several trips to study areas a total of 134 plant species distributed in 97 genera and 37 families were collected and identified. Based on the exhaustive interviews with indigenous people and medicinal plants references the medicinal plants of these plants were listed. Investigations were resulted that 67 species of these plants have medicinal uses. These medicinal species belongs to 31 families. Asteraceae with 11 species, Chenopodiaceae with 7 species and Lamiaceae with 6 species are the most important medicinal plants families. The major life forms of the medicinal plants in this area were annual herbs followed by perennial trees and shrubs with a proportion 34.32% and 26.86% respectively. 17.91% of the species are perennial herbs, 14.92% of the species are perennial bushes and 5.97% of species are annual bushes. Our results showed leaf and flower have the most traditional uses on Farashband tribe with a proportion 62.69% and 34.33% respectively.

The development of temporary threshold shifts among employees due to noise may lead to noise-induced hearing loss over time. The aim of this study is to explore occurrence of temporary standard threshold shifts on adopting different permissible exposure limits, 90 and 85 dBA. Countries such as Malaysia and US are adopting 90 dBA as permissible exposure limit. Materials and Methods:In this intervention study, there were 203 participants from two factories. They were exposed to noise levels above action level which is 85 dBA in one factory and 80 dBA in another factory, where permissible exposure limitswere 90 and 85 dBA respectively. The sample size required was 52 in each factory. Noise level was measured using personal exposure noise dosimeter and sound level meter. Data on standard threshold shifts were measured using manual audiometer. Hearing protection devices with appropriate noise reduction rate were used to reduce noise exposure among participants. Results: According to National Institute of Occupational Safety and Health recommended standard, there was statistically significant association between participants from both factories and standard threshold shift at 1000 Hz. This change was noted on left ear at sixth month,χ² (1) = 3.93, φ = – 0.211, p = 0.047, as per-protocol analysis. Conclusions:There were more threshold shifts on subjects adopting 90 dBA compared with 85 dBA. These temporary threshold shifts may progress to permanent threshold shifts over time. The prevalence of noise-induced hearing loss may be reduced on adoption of 85 dBA as permissible exposure limit.
