Simulation of mirror inversion of quantum states in an XY spin chain using NMR
We report an experimental quantum simulation of unitary dynamics of an XY
spin chain with pre-engineered couplings. Using this simulation, we demonstrate
the mirror inversion of quantum states, proposed by Albanese et al. [Phys. Rev.
Lett. 93, 230502 (2004)]. The experiment is performed with a 5-qubit dipolar
coupled spin system using nuclear magnetic resonance techniques. To perform
quantum simulation we make use of the recently proposed unitary operator
decomposition algorithm of Ajoy et al. [Phys. Rev. A 85, 030303 (2012)] along
with numerical pulse optimization techniques. Further, using mirror inversion,
we demonstrate that entangled states can be transferred from one end of the
chain to the other end. The simulations are implemented with high experimental
fidelity, which implies that these kind of simulations may be possible in
larger systems.Comment: 9 pages, 6 figure
A Comprehensive Revise on Discovering Public Media Psychological Disorders through Online Public Media Search
The explosive increase in social networking popularity results in problem usage. A number of social mental illnesses in the network have been reported, including cyber relationship dependence, overload of information and Net Compulsion. The symptoms of these psychiatric illnesses are mostly passively observed today and lead to delayed treatment procedure. We do not rely on self-review of these mental factors through questionnaires in psychology, as our methodology is new and groundbreaking with regard to SNMD detection. We instead provide a deep learning system that exploits features taken from the social network's data to correctly classify possible SNMD incidents. We also suggest the social network's mental disorder detection framework. In order to increase precision, we also use multi-source training in SNMDD and suggest a new SNMD-based tensor model. We further enhance reliability with accuracy guarantees in order to maximize STM's scalability. Our system is assessed by a sample analysis of 3126 apps. A function analysis and SNMDD on massive databases are performed and the properties of the three categories of SNMD analyzed. The findings demonstrate that SNMDD is good at finding consumers of future SNMDs online social network
Development of a creep data base management system for engineering materials
A fully menu driven creep data base management system has been developed for various high temperature materials using the client /server (C/S) architecture with Sybase system. 10 as backend and power builder 4.0 as an inter-face. The relational data base constitutes of various classes of materials, their heat treatment, prior history and the related creep properties at different test condit-ions, in addition to the source process route and chemical composition details.Top-down approach has been adopted in designing the entity-relationship (E-R) model. The creep data is organized into the third normal form, and the
entire system is divided into manageable modules. Coding for the system is done using Transact-SQL for data defin- ition, manipulation and control operations, and power script language for application development. This article briefly outlines the formulation of data base design, and the implemented E-R model, in addition , to the prese-ntation of various screen formats used for data entry and retrieval modules
Love Wave Propagation in Poro elasticity
It is observed that on similar reasons as in classical theory of elasticity, SH wave propagation in a semi infinite poroelastic body is not possible and is possible when there is a layer of another poro elastic medium over it i.e., Love waves. Two particular cases are considered in one of which phase velocity can be determined for a given wave length. In the same case, equation for phase velocity is of the same form as that of the classical theory of Elasticity
Transverse Wave Propagation in Relativistic Two-fluid Plasmas around Schwarzschild-anti-de Sitter Black Hole
The 3+1 formalism of Thorne and Macdonald has been used to derive the linear
two-fluid equations for transverse waves in the plasma closed to the
Schwarzschild-anti-de Sitter (SAdS) black hole. We reformulate the relativistic
two-fluid equations to take account of gravitational effects due to the event
horizon and negative cosmological constant and describe the set of simultaneous
linear equations for the perturbations. Using a local approximation we
investigate the one-dimensional radial propagation of Alfven and high frequency
electromagnetic waves. We derive the dispersion relation for these waves and
solve it for the wave number k numerically.Comment: 11 pages. arXiv admin note: substantial text overlap with

Effect of Dietary Protein Quality on the Biochemical Adaptation to High Altitude
The usefulness of a particular type of dietary protein for a quicker acclimatization to simulated high altitude stress was investigated in albino rats, by studying the changes occurring in the levels of urea cycle enzymes in liver. A good quality protein in (egg) and a commonly used dal protein (arhar dal, Cajanus cajan) were studied.Liver arginase levels increased on starvation in the two groups of rats fed with egg and dal diets, the increase being less and gradual in the dal diet fed group. Exposure to the simulated altitude stress for various periods further increased the enzyme levels, greater changes being seen in egg diet fed group only. Similar observations were made with liver ornithine transcarbamylase which is a mitochondrial enzyme. Urea cycle enzymes were affected more in the exposed animals maintained on the egg diet than those on the dal diet. Moreover, the enzymic parameters of the latter group tended to return to the normal level much earlier than the former. It is, therefore, suggested that not-so-well-balanced dietary proteins may be well suited to overcome the initial problem of metabolic adaptation faced by subjects exposed to high altitude stress
Analisa Sistem Perawatan Komponen Bearing Bottom Roller Dan V Belt Mesin Ring Frame Ry-5 Pada Departemen Spinning II a (Di PT Danliris Surakarta)
PT Danliris Surakarta merupakan Perusahaan textil dengan salah satu produk yang dihasilkan adalah benang, yang diproduksi melalui mesin-mesin Blowing, Carding, Drawing, Lap Form, Combing, Flyer, Ring Spinning dan Winder. Makalah ini mendeskripsikan pemilihan kebijakan repair dan preventive maintenance untuk mesin Ring Spinning (Ring Frame RY-5) pada komponen Bearing Bottom Roller dan V Belt, dimana pada komponen ini frekuensi kerusakan tinggi. Dari hasil pengamatan diketahui bahwa kebijakan repair dan preventive maintenance yang telah diterapkan kurang terorganisir, sehingga teknisi dan operator mengalami kesulitan dalam melakukan kegiatan perawatan mesin. Berdasarkan hal tersebut perlu dilakukan suatu penelitian untuk memilih kebijakan repair dan preventive maintenance policy yang efektif dan efisien dengan mempertimbangkan faktor biaya, frekuensi breakdown dan waktu down time. Tahapan yang digunakan dalam penyelesaian masalah dengan menentukan distribusi frekuensi breakdown, menghitung biaya kebijakan perawatan, memilih alternatif kebijakan berdasarkan besarnya biaya perawatan untuk mesin Ring Spinning (Ring Frame RY-5) pada komponen Bearing Bottom Roller dan V Belt. Dari hasil pengolahan dan analisa data, diperoleh alternatif kebijakan repair dan preventive maintenance sebagai alternatif yang dapat menurunkan biaya perawatan dan frekuensi breakdown
