Exploiting performance analysis of redundant system (

The present investigation seeks the steady state availability, reliability and mean time to failure of the 1-out-of (k + 1): G redundant system. A system having k active units (kM) and one unit (1S) as a warm standby redundancy have considered. The effects of various parameters on reliability measures have been analyzed by deriving two models. Model I is designed as a reliability model and Model II for steady state availability. The assumptions have been made that the detected faults in the redundant system is covered imperfectly. The Markov process, supplementary variable technique, Laplace transformation are adopted to determine the transient behavior of the system. Presented results based on numerical data to demonstrate the practical utilization of the developed models. This study is very helpful for the engineers to design a highly reliable redundant system with high profit in the industry

Stress and common dermatological disorders: The psychophysiological dermatoses

Primary dermatological disorders which are frequently exacerbated by stress and whose course is affected by the psychological state of the patient are called psychophysiologic or psychosomatic diseases. Psychosocial stress plays a major role in the onset and/or aggravation of these skin diseases. A close relationship between the skin and the mind mediated via hormones and neurotransmitters and altered cutaneous permeability barrier homeostasis by psychological stress constitute the basic psychopathology. The common skin conditions precipitated/aggravated by stress include psoriasis, vitiligo, atopic dermatitis, acne vulgaris, alopecia areata, urticaria, lichen planus, prurigo, seborrheic dermatitis, and hyperhidrosis. These cutaneous diseases often have a chronic, unpredictable course with multiple remissions and relapses leading to significant psychiatric morbidity, and disease-related stress further acts as an aggravating factor for the cutaneous disease leading to a vicious cycle. Increased awareness about these psychophysiologic diseases among dermatologists has helped to incorporate psychotherapeutic treatment in the form of psychotropic drugs and nonpharmacological interventions in the management of these patients. A multidisciplinary approach consisting of dermatologists along with psychiatrists and psychologists in a liaison framework has proven useful for these patients

Software reliability growth modeling for agile software development

The frequent incremental release of software in agile development impacts the overall reliability of the product. In this paper, we propose a generic software reliability model for the agile process, taking permanent and transient faults into consideration. The proposed model is implemented using the NHPP (non-homogenous Poisson process) and the Musa model. The comparison of the two implementations yields an effective, empirical and reliable model for agile software development

Analysis of series–parallel system’s sensitivity in context of components failures

This research examines the reliability characteristics of a broad series–parallel system. Complex system, having elements in series and parallel configuration is considered here to compute the reliability. Due to the failure of component, the system can either breakdown or can work with reduced frequency. To analyze the effect of component failure, sensitivity of the system with respect to reliability parameters is analyzed. In this study, generally distributed and exponentially distributed repair rates are taken into consideration from failed state to the working state of the system. The mathematical model of the designed structure is developed using Markov process and supplementary variable technique. The comparative study of the system availability and its sensitivity with respect to general distribution and general as well as exponential distribution has been examined. The Gumbel–Hougaard family of copula is used to analyze the effect of both the distributions together. For a better explanation of this work, a numerical example has been provided and shown the results graphically

Primary Burkitt’s lymphoma of medial part of clavicle- an extremely unusual site

Burkitt’s lymphoma is a subgroup of Non-Hodgkin’s lymphoma of high grade which is aggressive and composed of diffuse, undifferentiated malignant cells of lymphoid origin which are small and non cleaved. Clinical course is aggressive and rapid, commonly occurs in children and young adults with frequent involvement of Bone Marrow and CNS. It is considered as a medical emergency requiring immediate diagnostic and therapeutic intervention. We report a case of Burkitt’s lymphoma of medial part of clavicle extending into overlying pectoralis muscles, intercostal spaces, superior mediastinum, supraclavicular region. As per the literature available this is the first case of Burkitt’s lymphoma presenting primarily in medial part of clavicle
