Solving the Mystery of Crypto’s Bubble

Blockchain is the vehicle on which cryptocurrencies run, and it can’t be regulated by any legal entity during its operation.The huge growth in various cryptocurrency segments in 10 years has created the controversy of an inevitable bubble. A bubble can be generated either by queer herd behaviour or logical secular movement. Traces of evident bubbles have been a certainty and they take the perceived valuation of crypto to figures far away from its true value. This sudden diversion can be lethal due to the illogical, irrational propensity of regular market participants. This study observes ten cryptos under surveillance from September 2014 to August 2019. The selected ten (Monero, Bitcoin, XRP Ripple, Litecoin, Dogecoin, Monacoin, Ethereum, Bytecoin, Digibite, Potcoin) cryptocurrencies were studied for the last five years using Right Tailed ADF Test. Prominent traces of the rational bubble in all the underlying cryptocurrencies were found and have been considered for the study

Novel modelling of ultra-compact X-ray binary evolution - stable mass transfer from white dwarfs to neutron stars

Tight binaries of helium white dwarfs (He WDs) orbiting millisecond pulsars (MSPs) will eventually "merge" due to gravitational damping of the orbit. The outcome has been predicted to be the production of long-lived ultra-compact X-ray binaries (UCXBs), in which the WD transfers material to the accreting neutron star (NS). Here we present complete numerical computations, for the first time, of such stable mass transfer from a He WD to a NS. We have calculated a number of complete binary stellar evolution tracks, starting from pre-LMXB systems, and evolved these to detached MSP+WD systems and further on to UCXBs. The minimum orbital period is found to be as short as 5.6 minutes. We followed the subsequent widening of the systems until the donor stars become planets with a mass of ~0.005 Msun after roughly a Hubble time. Our models are able to explain the properties of observed UCXBs with high helium abundances and we can identify these sources on the ascending or descending branch in a diagram displaying mass-transfer rate vs. orbital period.Comment: 6 pages, 4 figures, MNRAS Letters, in pres

Performance Evaluation of AODV and DSDV Routing Protocols for Ad-hoc Networks

Ad-hoc networks are basically self organizing and self configuring multi-hop mobile wireless network in which the information packets are transmitted in a store and forward manner from a source to an arbitrary destination via intermediate nodes. The main objective of this paper is to performance evaluation of AODV (Ad-hoc on demand distance vector) and DSDV (Destination sequence distance vector) routing protocols on the basis of different performance metrics. In this paper, an attempt has been made to evaluate the performance of two well known routing protocols AODV, DSDV by using three performance metrics such as throughput, packet delivery ratio and Routing overheads. The Performance evaluation has been done by using simulation tool NS2 (Network Simulator) which is the main simulator

Various Sources and Mode of Burns: Descriptive Study

Background: The World Health Organization estimates that the lifetime incidence of severe burns is 1% and that more than 300,000 people die annually from fire-related burns worldwide.  Thermal injury is one of the major causes of morbidity & mortality in surgical patients & their successful management remains a challenge to modern medicine. Aim:  Study of various sources and mode of burn. Method: Total of 764 patients admitted to the surgical ward and burn unit were included in the study. On admission, preliminary inquiries were made regarding the demographic profile, cause, mode of burn injury, surface area, and depth of burns were noted. Result: In most of the burn patient, the cause of burn was flame (75.9%), followed by moist heat (17.27%) and electricity (6.67%). Maximum no. of burn cases the source of heat was chimney (42.28%), followed by the stove (15.18%), as the next most common source. In most of the patient were accidentally burnt (96.20%) among which the majority were females. Conclusion:   The most common cause of burn injury was flame. In most burn patients, the source of heat was a chimney, and most of the burn injuries were accidental. Keywords:  Burns; Source; Mode of injury

To Study the Effect of Job Satisfaction on the Performance of Academic Faculties Working in Private Colleges and Private Universities in Indore

The objective of the existing study was to examine the impact of job satisfaction on the performance of employees working in private colleges and universities in Indore, India. To achieve this, questionnaires were distributed to a total of 60 employees, out of which 54 responses were received and considered as the sample from private colleges and universities in Indore. An equal number of employees (n = 54) were randomly selected from different types of organizations, including undergraduate and postgraduate colleges, as a comparison group. The study utilized a self-constructed questionnaire based on the Minnesota Satisfaction Questionnaire (MSQ-quick form) developed by Weiss et al. (1967), as well as a self-constructed Performance Evaluation Form (PRF). Initially, the reliability of both instruments was assessed to determine the significance of the scales. The study findings indicated a significant correlation between the type of occupation and job satisfaction. Moreover, a positive relationship between job satisfaction and employee performance was also observed. Therefore, the study concluded that satisfied employees performed better compared to dissatisfied employees, thus playing a significant role in the advancement of their organizations. Consequently, it is crucial for every organization to adopt specific strategies and methods to motivate and ensure employee satisfaction, thereby promoting high performance

Reliability Analysis of an Engine Assembly Process of Automobiles with Inspection Facility

Present paper studies the reliability analysis of an engine assembly system incorporating inspection facility. The engine system consists of nine main units namely: Cylinder block, Crank shaft, Oil sump, Piston, Cylinder head gasket, Cam shaft gear, Crank shaft gear, Fuel injection pump and High pressure line. The whole system can fail due to failure of any of the units. It is also assumed that the system can fail due to catastrophic failure. The system satisfies the usual conditions like perfect repair, random variables, joint distributions etc. Each operative unit has a constant failure rate but a general repair time distribution. We transform the basic equation into integro differential equation and outline the solution procedure for a repair time distribution with an arbitrary rational Laplace transform. Various reliability characteristics such as transition state probabilities, steady state behavior, availability, reliability, MTTF and cost analysis have been obtained using a time dependent version of the supplementary variable method and Gumble-Hougaard copula methodology. Some particular cases and asymptotic behaviour of the system have also been derived to improve practical importance of the model.
