In this paper we consider a local area network (LAN) of dual mode service where one is a token bus and the other is a carrier sense multiple access with a collision detection (CSMA/CD) bus. The objective of the paper is to find the overall cell/packet dropping probability of a dual mode LAN for finite length queue M/G/1(m) traffic. Here, the offered traffic of the LAN is taken to be the equivalent carried traffic of a one-millisecond delay. The concept of a tabular solution for two-dimensional Poisson's traffic of circuit switching is adapted here to find the cell dropping probability of the dual mode packet service. Although the work is done for the traffic of similar bandwidth, it can be extended for the case of a dissimilar bandwidth of a circuit switched network.

Software Quality Assurance Testing time computer vision based automation tools are used to test the window based application and window based application is combined of many objects. Among them most of the automation tool detect window objects by comparing images. Most of the objects are visible in the window screen but some objects which are not visible to the screen at the first time. Proper interaction with the window application hidden objects get visible to the screen like dropdown list item, editor text object, list box item and slider. With the automation tools these hidden objects cannot be searched directly. In this paper proposes some methods which will enhance the automation tools to access the window application hidden objects.

An in vitro experiment was carried out to evaluate the effectiveness of antibiotics at different concentrations on growth and development of Trichoderma harzianum, Phytophthora infestans, Colletotrichum gloeosporioides, Corticium theae and Fusarium oxysporum found in tea plantation. Three samples viz. sample-1 (Validamycin 60% w/w) @ 45, 60 and 75 ppm, sample-2 (Hexaconazole 2.5% w/w+Validamycin 8.5% w/w) @ 55, 82.5 and 110 ppm and sample-3 (Streptomycin 9% w/w+Tetracyclin hydrochloride 1% w/w) @ 50, 75 and 100 ppm were tested. The result showed that Antibiotics have inhibitory effects on T. harzianum. Unsatisfactory performances in terms of per cent growth inhibition (<80) were recorded on crop infecting fungi. C. theae treated with sample-1 @ 75 ppm and C. gloeosporioides with sample-2 @ 110 ppm had shown maximum 25.50 and 54.19 per cent growth inhibition, respectively. The highest 70.53 per cent growth inhibition of C. theae was observed in sample-3 treated @ 100 ppm. Considering the findings it can be recommended not to use above antibiotics with their respective concentrations in plant agriculture for controlling diseases caused by the said fungi.

Abstract

Now-a-days hundreds of millions of people of almost all levels of education and attitudes from different country communicate with each other for different purposes and perform their jobs on internet or other communication medium using various languages. Not all people know all language; therefore it is very difficult to communicate or works on various languages. In this situation the computer scientist introduce various inter language translation program (Machine translation). UNL is such kind of inter language translation program. One of the major problem of UNL is identified a name from a sentence, which is relatively simple in English language, because such entities start with a capital letter. In Bangla we do not have concept of small or capital letters. Thus we find difficulties in understanding whether a word is a proper noun or not. Here we have proposed analysis rules to identify proper noun from a sentence and established post converter which translate the name entity from Bangla to UNL. The goal is to make possible Bangla sentence conversion to UNL and vice versa. UNL system prove that the theoretical analysis of our proposed system able to identify proper noun from Bangla sentence and produce relative Universal word for UNL.
