Estimating Lower Bound and Upper Bound of a Markov chain over a noisy communication channel with Poisson distribution
Mr. Vinay Mahajan,Prof. Rajesh Nema
International Journal of Advanced Computer Research , 2012,
Abstract: Under the assumption that the encoders’ observations are conditionally independent Markov chains given an unobserved time-invariant random variable, results on the structure of optimal real-time encoding and decoding functions are obtained. The problem with noiseless channels and perfect memory at the receiver is then considered. A new methodology to find the structure of optimal real-time encoders is employed. A sufficient statistic with a time-invariant domain is found for this problem. This methodology exploits the presence of common information between the encoders and the receiver when communication is over noiseless channels. In this paper we estimate the lower bond, upper bond and define the encoder. In the previous design approach they follow Markov Chain approach to estimating the upper bound and define the encoder. In this dissertation we follow poison distribution to finding the lower bound and upper bound. Poisson can be viewed as an approximation to the binomial distribution. The approximation is good enough to be useful even when the sample size (N) is only moderately large (say N > 50) and the probability (p) is only relatively small (p < .2) The advantage of the Poisson distribution, of course, is that if N is large you need only know p to determine the approximate distribution of events. With the binomial distribution you also need to know N.
Comparative evaluation of RT-PCR with sandwich-ELISA for detection of Peste des petits ruminant in sheep and goats

Abstract: Aim: To assess the suitability, sensitivity and specificity of F gene based RT-PCR for detection of PPRV infection in India. Materials and Methods: A total of 26 blood samples collected from 26 animals suspected for Peste des petits ruminant (PPR) were tested by RT- PCR using F1/F2 primers set and then compared with sandwich-ELISA for detection of PPR virus. Results: Out of 26 samples tested RT-PCR reported 10 (38.46%) samples as positive as compared to Sandwich-ELISA which reported 11(42.30%) samples as positive for PPR virus. Further analysis of samples revealed that 3 (11.53%) samples which were negative by sandwich-ELISA reported positive with RT-PCR. Whereas 4 (15.38 %) samples shown negative by RT-PCR were positive with sandwich-ELISA. The relative sensitivity and specificity of F-gene based RT-PCR when compared with sandwich-ELISA was 63.60% and 80.00%, respectively. The overall agreement between the two tests was of 73.10% with kappa value 0.442, which suggesting a moderate agreement between the two tests. Conclusion: A low sensitivity and specificity along with moderate agreement shown by F- gene based RT-PCR when compared with sandwich ELISA suggests that some other highly sensitive and specific primers should be explored for detection of PPR by RT-PCR.

Existence of Black Neutron Star  [PDF]
Trivedi Rajesh
International Journal of Astronomy and Astrophysics (IJAA) , 2015, DOI: 10.4236/ijaa.2015.51002
Abstract: A sufficiently large star will collapse to form a Black Hole Singularity due to Gravitational Pressure beyond Neutron Degeneracy. A Black Hole exhibits extremely strong Gravitational attraction that no particle or electromagnetic radiation can escape from it. The boundary of the region from which no escape is possible is called Event Horizon. In this work it is proposed that there exists a Neutron star smaller than Event Horizon, which is termed as Black Neutron Star. Furthermore an alternative method is proposed to ascertain the maximum permissible mass limit of the Neutron Star and the minimum mass limit of the naturally occurring gravitationally collapsed Black hole.
Energy Efficient Path Determination in Wireless Sensor Network Using BFS Approach  [PDF]
Shilpa Mahajan, Jyoteesh Malhotra
Wireless Sensor Network (WSN) , 2011, DOI: 10.4236/wsn.2011.311040
Abstract: The wireless sensor networks (WSN) are formed by a large number of sensor nodes working together to provide a specific duty. However, the low energy capacity assigned to each node prompts users to look at an important design challenge such as lifetime maximization. Therefore, designing effective routing techniques that conserve scarce energy resources is a critical issue in WSN. Though, the chain-based routing is one of significant routing mechanisms but several common flaws, such as data propagation delay and redundant transmission, are associated with it. In this paper, we will be proposing an energy efficient technique based on graph theory that can be used to find out minimum path based on some defined conditions from a source node to the destination node. Initially, a sensor area is divided into number of levels by a base station based on signal strength. It is important to note that this technique will always found out minimum path and even alternate path are also saved in case of node failure.
Navigating the Current Location without the Availability of GPS
Karan Mahajan,Manish Mahajan
International Journal of Engineering and Advanced Technology , 2013,
Abstract: Today in this world we are surrounded of technologies like smart phone technology.In smart phone there is an option GPS that is being used these days very much for checking in our location and navigate the google maps.But what about those cell phones which are having ANDROID operating system but no having option of GPS.This paper deals with the NAVIGATING THE CURRENT LOCATION WITHOUT THE AVAILABILITY OF GPS.Because GPS is having some limitations.First GPS may or may not be available in all smart phones.This application which we developed will work in the phones which are not having feature of GPS.

Supplemental root in a mandibular first molar: a rarity
Poonam Mahajan,Ajay Mahajan
Clinics and Practice , 2011, DOI: 10.4081/cp.2011.e10
Abstract: Anatomic variations are common in human dentition. A clear understanding of these variations is very important for success of endodontic treatment. A dentist should be aware of these anatomic variations as this can affect the treatment outcome. A case of endodontic therapy is presented in which inability to locate an anatomically rare supplemental canal of a three rooted mandibular first molar resulted in treatment failure. A 21-year-old female reported with pain and swelling in relation to lower right first molar. An intra oral periapical radiograph revealed 3 roots; the first canal of the mesial root and a canal of one of the distal roots were found to be treated endodontically, which were infraobturated but the canal of the 2nd distal root had not been treated. The radiograph revealed periapical radiolucency and widening of periodontal space. Prior to starting the endodontic treatment the clinician must be aware of the anatomic variations in tooth pulp morphology and also the importance of preoperative radiographs cannot be underscored.
Head CT is of limited diagnostic value in critically ill patients who remain unresponsive after discontinuation of sedation

Abstract: A retrospective review of adult (age >18 years of age) patients consecutively admitted to the medical intensive care unit of a tertiary care medical center. Patients requiring mechanical ventilation for management of respiratory failure for longer than 72 hours were included in the study group. A group that did not have difficulty with awakening was included as a control.The median time after sedation was discontinued until a head CT was performed was 2 days (interquartile range 1.375–2 days). Majority (80%) of patients underwent head CT evaluation within the first 48 hours after discontinuation of sedation. Head CT was non-diagnostic in all but one patient who had a small subarachnoid hemorrhage. Twenty-five patients (60%) had a normal head CT. Head CT findings did not alter the management of any of the patients. The control group was similar to the experimental group with respect to demographics, etiology of respiratory failure and type of sedation used. However, while 37% of subjects in the control group had daily interruption of sedation, only 19% in the patient group had daily interruption of sedation (p < 0.05).In patients on mechanical ventilation for at least 72 hours and who remain unresponsive after sedative discontinuation and with a non-focal neurologic examination, head CT is performed early and is of very limited diagnostic utility. Routine use of daily interruption of sedation is used in a minority of patients outside of a clinical trial setting though it may decrease the frequency of unresponsiveness from prolonged sedation and the need for head CT in patients mechanically ventilated for a prolonged period.Sedation is frequently required for comfort in patients who require mechanical ventilation for management of respiratory failure, but it is associated with the common complication of delayed awakening. While daily interruption of sedatives has been suggested to reduce ventilator and intensive care unit (ICU) days by avoiding delays in patient awake
