In this paper, Bayes estimator is derived for the parameter of the exponential model with presence of outliers based on records value. This estimator compared with estimator when we not use of records value.

The English pronunciation of the Panjabi learners is highly aggressive giving rise to defective pattern of speech in English. For example they don’t use labio-dental sounds or they are unaware of silent sounds in English words like /m/ in tomb. The present paper aims to analyze the phonetic and phonological patterns of English and Panjabi as taught by teachers in some schools. The structural approach is preferred over other approaches in this paper. This approach suits to English and Panjabi as the phonological structures of both the languages is of contrastive nature rather than identical or similar one. Both the languages are spoken and used in teaching. The structure is taken as an arrangement and combination of phonological units, not in the sense that of as grammarians use like word structure, noun formation, morphological constructions, etc. Veritably, Panjabi is written as it is spoken, whereas English is not spoken, as it is written, thereby causing doubts in the minds of the learners.

The use of tractors for agricultural works showed an important role to mechanized agricultural sector. A repairable mechanical system (as agricultural tractor) is subject to deterioration or repeated failure. In this study, the regression model was used to predict the failure rate of MF399 tractor. The machine failure pattern was carefully studied and key factors affecting the failure rate were identified in five regions of Khouzestan province. Results showed that different annual use hours (AUH) and maintenance policies affected failure rate. According to the data, the MF399 tractors included in 300-1000 AUH were commonly in a randomized breakdown period during their useful life but these tractors tend to enter the wear out period in the 1200-2000 AUH.

The problem of Reoptimization of Steiner Tree is a NP Hard problem. Given a graph and a optimal solution of the Steiner tree and then after a slight modification is done in the initial instance, then a new Steiner minimal tree is to be determined. This is known as reoptimization of Steiner Tree. Several cases of reoptimization of Steiner tree have been discussed. This paper presents a comparative analysis of some of the previous work done on reoptimization of Steiner Tree.

Wave propagation method (WPM) is utilized, for the first time, to study the resonance response of Atomic Force Microscopy (AFM). The damping coefficient with in the interaction of tip-sample, which is assumed as a linear visco-elastic force, is considered in this paper as it has been neglected in the WPM studies of beam in previous investigations. Experiment and analytical results are provided in order to show the reliability and correctness of WPM method. The results are in good agreements with the experiments and show that the WPM is more accrue than analytical method.

The anti MRSA properties of mango seed kernel ethanol extract (MKE) were investigated. The MKE was separated by reverse phase HPLC with acetonitrile linear gradient and also identified by Nuclear Magnetic Resonance (NMR), Mass Spectroscopy (MS) and Infrared (IR) for structural characterization of antimicrobial tannin compounds. It showed significant activity against Methicillin Resistant Staphylococcus aureus (MRSA) at the MIC of 0.03mg/ml. These results indicated that the active component of the MKE was a type of complex Tannin.

Finding Shortest path in a graph has been the area for many researchers. Shortest path is one of the fundamental and most widely used concepts in networks. Here, we discuss the Shortest Path Length (SPL) from a specified vertex to all other vertices in a network. For illustration, a real life example has been considered from Chennai to kanyakumari roadways transport network.

Industrial sickness is a universal phenomenon, over the years the problem of the industrial sickness has grown not only in developing countries but also in developed countries. In India, the problem of sickness in industries has become very acute. It adversely affected the health of the industrial sector in particular and the economy of the country in general. This paper covers the causes of sickness in the cooperative sugar factories in Andhra Pradesh with reference to NCSF and to examine the revival / closure strategy of NCSF. The present study is based on secondary data and is substantiated by discussions and interviews with the officials of NCSF. The data is analysed by using appropriate statistical tools like averages, trend analysis and percentages. In order to identify the forewarning indicators of industrial sickness in Cooperative sugar factories, L.C. Gupta model of four financial ratios such as (1) EBDIT \ NS (2) EBDIT \ GTA (3) OCF \ NS (4) OCF \ GTA are also applied. It concludes that the originating factor was management ineffectiveness. The management could not make the farmers understand the importance of survival of NCSF. The management could not convince the farmers to continue to produce sugarcane for their survival vis-à-vis the NCSF’s survival. EBT was negative for all the years but for 1998-99 it was positive due to interest waived. All these indications show that the organization was never sound, ultimately leading to sickness.
