Cutaneous metastatic adenocarcinoma
Joshi Arun,Sah Shatrughan
Indian Journal of Dermatology, Venereology and Leprology , 2001,
Abstract: A 5.5-year-old male presented with asymptomatic nodules and plaques on his scalp and pubic region of 2 months′ duration. He was having productive cough, haemoptysis, chest pain, anorexia and weight loss and receiving antitubercular treatment for these symptoms for last 3 months. Clinical diagnosis of cutaneous metastatic disease was made. Chest x-ray revealed multiple coin shaped shadows on both sides with pleural effusion. Routine investigations were normal except for anemia and hyperuricemia. Biopsy of skin nodules showed features of metastatic adenocarcinoma. Features and significance of cutaneous metastases are discussed.

Abstract: A 34 year old Nepalese male presented with 10 year history of recurrent itchy erythematous papules, plaques and vesicles healing with scarring and milia on his shins. He also had dystrophic toenails since childhood. Family and past history were not contributory. Histopathological findings were consistent with the clinical diagnosis of pretibial epidermolysis bullosa (PEB). The patient was treated with oral vitamin E with some relief.
Cutaneous T-Cell Lymphoma : An Unusual Presentation
Joshi Arun,Sah Shatrughan P,Rani Sudha,Kalra O P
Indian Journal of Dermatology , 2002,
Abstract: A 38 year old Nepalese man presented with a large red tender plaque on his back of 15 days duration. He had a history of fever, cough, chest pain and haemoptysis for 4 months. On examination, he also had pallor lymphadenopathy and hepatomegaly. Investigations revealed anaemia, marked leucocytosis with 45% atypical cells and thrombocytopenia. Chest X-ray showed consolidation and bone marrow examination revealed abnormal cells. Skin biopsy had features of cutaneous T-cell lymphoma (CTCL). We report this rare presentation of CTCL with simultaneous visceral and haematological involvement.

Saving Environment Using Internet of Things: Challenges and the Possibilities  [PDF]
Praneet Sah
Advances in Internet of Things (AIT) , 2016, DOI: 10.4236/ait.2016.64004
Abstract: The term Internet of Things (IoT) emerged in the early 2000s but actually gained momentum only in the past few years, however we still do not get to see them in our daily life. It has generally been avoided by the mainstream market due to its cryptic nature which requires technical knowledge prior to its use. Lack of strong business model (by companies) and inability to adapt to new rapid changes (by consumers) are the two primary factors contributing to the fact that IoT is well ahead of its times but it need no longer be. In this paper, Ive created a setup for smart home that allows the users to control their electrical appliances from internet and even makes the appliances smart enough to react to the environmental conditions on their own. Using this setup, I observed the pattern in which electricity consumption and carbon footprints reduced as compared to the conventional setup i.e. without IoT. Analyzing this data provided me a solid proof that IoT definitely helps us to save electricity and environment. Since IoT is beneficial for all, I, then focused on the challenges that are hampering the penetration of IoT into the daily lives of consumers and how the consumer is overlooking the benefits that it has to offer, which even includes a primary concern for many, i.e. saving money. This paper is overall aimed to change the way a consumer thinks about IoT and to provide a solid ground to how it is beneficial.
Spherical Anisotropic Fluid Distribution in General Relativity  [PDF]
A. Sah, Prakash Chandra
World Journal of Mechanics (WJM) , 2016, DOI: 10.4236/wjm.2016.612034
Abstract: In the present investigation of a spherically symmetric electrically neutral anisotropic static fluid, we present a new solution of the Einstein’s general relativistic field equations. The solution shows positive finite central pressures, central density and central red shift. The causality condition is obeyed at the centre. The anisotropy parameter is zero at the center and monotonically increasing toward the surface. The adiabatic index is also increasing towards the surface. All the other physical quantities such as matter-energy density, radial pressure, tangential pressure, velocity of sound and red shift are monotonically decreasing towards the surface. Further by assuming the surface density?\"\", we have constructed a model of massive neutron star with mass 2.95?\"\"?with radius 18 km with all degree of suitability.
Class of Charged Fluid Balls in General Relativity  [PDF]
A. Sah, Prakash Chandra
International Journal of Astronomy and Astrophysics (IJAA) , 2016, DOI: 10.4236/ijaa.2016.64038
Abstract:

In the present study, we have obtained a new analytical solution of combined Einstein-Maxwell field equations describing the interior field of a ball having static spherically symmetric isotropic charged fluid within it. The charge and electric field intensity are zero at the center and monotonically increasing towards the boundary of the fluid ball. Besides these, adiabatic index is also increasing towards the boundary and becomes infinite on it. All other physical quantities such as pressure, density, adiabatic speed of sound, charge density, adiabatic index are monotonically decreasing towards the surface. Causality condition is obeyed at the center of ball. In the limiting case of vanishingly small charge, the solution degenerates into Schwarzchild uniform density solution for electrically neutral fluid. The solution joins smoothly to the Reissner-Nordstrom solution over the boundary. We have constructed a neutron star model by assuming the surface density \"\". The mass of the neutron star comes \"\" with radius 14.574 km.

Automated Coin Recognition System using ANN
Shatrughan Modi,Dr. Seema Bawa
Computer Science , 2013, DOI: 10.5120/3093-4244
Abstract: Coins are integral part of our day to day life. We use coins everywhere like grocery store, banks, buses, trains etc. So it becomes a basic need that coins can be sorted and counted automatically. For this it is necessary that coins can be recognized automatically. In this paper we have developed an ANN (Artificial Neural Network) based Automated Coin Recognition System for the recognition of Indian Coins of denomination Rs. 1, 2, 5 and 10 with rotation invariance. We have taken images from both sides of coin. So this system is capable of recognizing coins from both sides. Features are extracted from images using techniques of Hough Transformation, Pattern Averaging etc. Then, the extracted features are passed as input to a trained Neural Network. 97.74% recognition rate has been achieved during the experiments i.e. only 2.26% miss recognition, which is quite encouraging.
Image Processing based Systems and Techniques for the Recognition of Ancient and Modern Coins
Shatrughan Modi,Dr. Seema Bawa
Computer Science , 2013, DOI: 10.5120/7221-0041
Abstract: Coins are frequently used in everyday life at various places like in banks, grocery stores, supermarkets, automated weighing machines, vending machines etc. So, there is a basic need to automate the counting and sorting of coins. For this machines need to recognize the coins very fast and accurately, as further transaction processing depends on this recognition. Three types of systems are available in the market: Mechanical method based systems, Electromagnetic method based systems and Image processing based systems. This paper presents an overview of available systems and techniques based on image processing to recognize ancient and modern coins.
A Spherical Relativistic Anisotropic Compact Star Model  [PDF]
Prakash Chandra Fulara, Archana Sah
International Journal of Astronomy and Astrophysics (IJAA) , 2018, DOI: 10.4236/ijaa.2018.81004
Abstract: We provide solutions to Einsteins field equations for a model of a spherically symmetric anisotropic fluid distribution, relevant to the description of compact stars. The central matter-energy density, radial and tangential pressures, red shift and speed of sound are positive definite and are decreasing monotonically with increasing radial distance from the center of matter distribution of astrophysical object. The causality condition is satisfied for complete fluid distribution. The central value of anisotropy is zero and is increasing monotonically with increasing radial distance from the center of the distribution. The adiabatic index is increasing with increasing radius of spherical fluid distribution. The stability conditions in relativistic compact star are also discussed in our investigation. The solution is representing the realistic objects such as SAXJ1808.4-3658, HerX-1, 4U1538-52, LMC X-4, CenX-3, VelaX-1, PSRJ1614-2230 and PSRJ0348+0432 with suitable conditions.
