Comparative Analysis of Free Space Optics and Single Mode Fiber

In this paper we have done comparative analysis of free space optics and single mode fibre optical channels system. Performance study is done for variable ranges 1km, 50km and 100km for the FSO and SMF channels. Single Mode Fiber and Free Space Optical Channel is observed that maximum Q factor, minimum bit error rate and signal power. FSO requires no licensing or frequency synchronization. It also provides the transmission of data with unlimited bandwidth. Results expose the ability of improving the Q factor by using these channels and the optimum effect concluded at (1km) length of optical rang by using the FSO channel i.e. the quality factor and signal power were increased to reach (1943 ) and (22.46dBm) respectively and MIN. BER is zero

Ayurveda Perspective on Balatisara; Common Causes, Symptoms and Ayurveda Management

Balatisara (Diarrhea) is a disease of children mainly involves symptoms of disturbed bowel movements. As per ayurveda Atisar can be classified into seven category; Vataja, Pittaja, Kaphaja, Bhayaja, Tridoshaja, Shokaja and Raktatisara. The Balatisara affects large number of population world widely and prevalence of diarrhea now a day’s deteriorating school performance of many children. Lack of immunity, susceptibility towards the causative pathogen, low hygienic condition, malnutrition and consumption of contaminated food items can cause Balatisara. Increases frequency of defecation, disturbed electrolyte balance, thirst, weakness, gas formation and abdomen cramps are the common symptoms of Balatisara. Nidana Sevana vitiates Vata leading to the Mandagni and Koshta shoonata increases Dravata in Pureesha in Pakwashaya which finally resulted Atisara. The therapeutic measure must requires consideration of Doshas condition; Alpa, Madhya or Bahumatra of Doshas. Langana can be done if Doshas are Alpa, Langana leads Agnideepana which resulted Aamapachana action. Present article described ayurveda perspective of Balatisara including causes, symptoms and management. Keywords: Ayurveda, Balatisara, Diarrhea, Herbs. &nbsp

Science with the Daksha High Energy Transients Mission

We present the science case for the proposed Daksha high energy transients mission. Daksha will comprise of two satellites covering the entire sky from 1~keV to $>1$~MeV. The primary objectives of the mission are to discover and characterize electromagnetic counterparts to gravitational wave source; and to study Gamma Ray Bursts (GRBs). Daksha is a versatile all-sky monitor that can address a wide variety of science cases. With its broadband spectral response, high sensitivity, and continuous all-sky coverage, it will discover fainter and rarer sources than any other existing or proposed mission. Daksha can make key strides in GRB research with polarization studies, prompt soft spectroscopy, and fine time-resolved spectral studies. Daksha will provide continuous monitoring of X-ray pulsars. It will detect magnetar outbursts and high energy counterparts to Fast Radio Bursts. Using Earth occultation to measure source fluxes, the two satellites together will obtain daily flux measurements of bright hard X-ray sources including active galactic nuclei, X-ray binaries, and slow transients like Novae. Correlation studies between the two satellites can be used to probe primordial black holes through lensing. Daksha will have a set of detectors continuously pointing towards the Sun, providing excellent hard X-ray monitoring data. Closer to home, the high sensitivity and time resolution of Daksha can be leveraged for the characterization of Terrestrial Gamma-ray Flashes.Comment: 19 pages, 7 figures. Submitted to ApJ.
