Applications such as video and audio streaming, online gaming, video conferencing, Voice over IP (VoIP) and File Transfer Protocol (FTP) demand a wide range of QOS requirements such as bandwidth and delay. IEEE 802.16 standard called WIMAX provides broadband wireless access with QOS requirements. The proposed work consists of a new uplink scheduling and Call Admission Control (CAC) algorithm for preferential treatment of service flows depending on QOS requirements. Using this scheduling and Call Admission Control algorithm fairness enhancement, with more connection acceptance.Keywords

Ten accessions of traditional french beans - types were collected from different elevations and evaluated for yield and quality at Nanjanad Farm, HRS, Ooty. The 10 entries of bush beans were evaluated in a Randomized Block Design with 3 replications at Nanjanadu Farm, HRS, Ooty. Observations were taken on growth and yield characters from 2010 onwards. Observation on plant height, number of branches, number of compound leaves, days taken of flowering, number of pods, days taken for pod setting, pod length, pod diameter and pod weight per plant were recorded. As indicated in the pooled means of four years from 2010 to 2013, among the bush bean types, accession number FBB-7 (Aruvath avarai) has recorded highest pod yield of 712.73 g/plant and pod weight of 15. 80g/ pod. The highest genotypic coefficient of variation was observed for number of leaves, pod weight and yield. High heritability values were observed in plant height, number of branches, number of leaves, days for flowering and pod development, pod length, pod diameter, pod weight and yield. The expected genetic advance expressed as percentage of mean was relatively high for the characters viz., plant height, branch, number of leaves, days for flowering, days for pod development, pod length, pod diameter, pod weight and yield.

Manufacturing Technology Today, Vol 4, No 9 (2005), Pagination: 25-27Abstract
Due to the shortage of experienced process engineers and need for automation in manufacturing, the role of computers in process planning becomes inevitable. The integration of CAD, CAPP and CAM greatly shortens the product lead time. But true integration of CAD and CAM activities can take place only when the manufacturing information can be obtained from the CAD solid model and hence automate the process planning. The link between design and manufacturing represents a vast field of research, and its growth is crucial to the success of the CAD/CAM industry. This success mainly depend upon the, how reliably the data's are exchanged from various CAD systems to CAM systems. The existence of incompatibilities between information technology systems used in the process of design, engineering and manufacturing has given rise to various data exchange problems. These problems are of particular concern as more and more concurrent design is being undertaken by collaboration of different organizations that utilize different application programs and operating systems. The following section discusses the general problems that are often encountered during exchange of data, which result in increased cost and can be reduced or eliminated through the use of STEP.- Combined Inoculation Effect of Pink Pigmented Facultative Methylobacterium (PPFM) and other Bioinoculants on Cotton

A field study was conducted to evaluate the individual and combined inoculation effect of PPFM and other bioinoculants on cotton. Initially a detailed survey was conduced in different agro climatic zones of Tamilnadu to isolate an efficient strain of Methylobacterium. Isolated PPFM strains were analyzed through polymerase chain reaction (PCR) for the presence of mdh gene using mdh gene specific probes. Only the isolates having the expected size of mdh gene product were chosen for further studies. Selected isolates were screened for plant growth promoting efficiency through vigor index studies. In the field trial conducted with cotton crop, PPFM was inoculated with a diazotroph and a phosphate solubilizing organism (PSB) as individual and combined inoculant treatments. PPFM inoculation has resulted in increased seedling vigor, drymatter production and yield. Inoculation of all the three inoculants together has resulted in increased rhizosphere population of the inoculants, drymatter production and yield.Keywords

Soil potential to store organic carbon was assessed in the hot sub-humid dry Agro-Ecological Region (AER) of the Indo-Gangetic Plains under Recent alluvium of southern Bihar, India. The study was carried out in four prevailing cropping systems, viz. Rice–Wheat– Fallow (R–W–F), Pearl millet–Wheat–Fallow (P–W– F), pigeon pea (monoculture) and vegetable cultivation. Two different recovery factors were used to estimate Total Organic Carbon (TOC), which yielded similar results. The Soil Organic Carbon (SOC) was found highest in pigeon pea-grown soils (69.2 tonnes ha–1) followed by R–W–F (56.2 tonnes ha–1) and vegetable cultivation (55.8 tonnes ha–1). The lowest SOC stock was found with P–W–F (19.2 tonnes ha–1). The differences in SOC stock between pigeon pea and that of rice–wheat, vegetables and pearl millet–wheat are 13.0, 13.4 and 50.0 t ha–1 respectively, that are the quantity of organic carbon can be sequestered further in these three land uses from 47.71, 49.12 and 183.50 tonnes of carbon dioxide from the atmosphere respectively. Highly significant positive correlation of soil qualities parameters such as available nitrogen (r2 = 0.25), copper (r2 = 0.45), zinc (r2 = 0.31) and dehydrogenase activity (r2 = 0.44) was found with SOC stock under the hot, sub-humid, dry, AER of southern Bihar. Similar assessment can be done in any AER and the potential of soils can be identified to increase carbon sequestration from the atmosphere.Keywords
