Design and Development of Commuter Services Model in Trains using Cloud
Manne Sai Rakesh,S. Venkatesh Sundarasetty,P. Ramesh Pasupuleti,A. Umamakeswari
Journal of Artificial Intelligence , 2013,
Abstract: The cloud technology is becoming ubiquitous and making the things easier. The idea is to seep this technology into the trains and other transport systems also. Without technology, transport system is more complicated and boring and these can compensated with cloud. A central server on the train, with memory, processing capacity, internet connectivity and with a local network throughout the train (access points in each compartment or use directional antennas) could be of great use to passengers, railway authority and police. The technology improvement goes in hand with the use of clouds on train. With help of Global Positioning System (GPS) and internet, cloud can predict the train clash possibility and alert the concerned authority. This cloud can be used for some of the services like software as a service, infrastructure as a service, etc., and also enjoy on demand services like video streaming, etc., locally. The server can also be used by railway authority for updating the passenger details and know about vacancy of berths and other information which makes it easy for them to know anything at the snap of the finger, even when there is no connectivity between bogies. The cloud can be used to collect the information about the surroundings and give the notifications to the user/whoever is connected to the server.
Certain Algebraic Test for Analyzing Aperiodic Stability of Two-Dimensional Linear Discrete Systems  [PDF]
P. Ramesh
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.76061
Abstract: This paper addresses the new algebraic test to check the aperiodic stability of two dimensional linear time invariant discrete systems. Initially, the two dimensional characteristics equations are converted into equivalent one-dimensional equation. Further Fuller’s idea is applied on the equivalent one-dimensional characteristics equation. Then using the co-efficient of the characteristics equation, the routh table is formed to ascertain the aperiodic stability of the given two-dimensional linear discrete system. The illustrations were presented to show the applicability of the proposed technique.
Stability Analysis of Multi-Dimensional Linear Time Invariant Discrete Systems within the Unity Shifted Unit Circle  [PDF]
P. Ramesh
Circuits and Systems (CS) , 2016, DOI: 10.4236/cs.2016.76060
Abstract: This technical brief proposes a new approach to multi-dimensional linear time invariant discrete systems within the unity shifted unit circle which is denoted in the form of characteristic equation.The characteristic equation of multi–dimensional linear system is modified into an equivalentone- dimensional characteristic equation. Further formation of stability in the left of the z-plane, the roots of the characteristic equationf(z) =0 should lie within the shifted unit circle. Using the coefficients of the unity shifted one dimensional equivalent characteristic equation by applying minimal shifting of coefficients either left or right and elimination of coefficient method to two triangular matrixes are formed. A single square matrix is formed by adding the two triangular matrices. This matrix is used for testing the sufficient condition by proposed Jury’s inner determinant concept. Further one more indispensable condition is suggested to show the applicability of the proposed scheme. The proposed method of construction of square matrix consumes less arithmetic operation like shifting and eliminating of coefficients when compare to the construction of square matrix by Jury’s and Hurwitz matrix method.

JAGADEESH PASUPULETI
Journal of Engineering Science and Technology , 2006,
Abstract: The IEEE bench mark model 2 series compensated system is considered for analysis. It consists of single machine supplying power to infinite bus through two parallel lines one of which is series compensated. The mechanical system considered consists of six mass, viz, high pressure turbine, intermediate pressure turbine, two low pressure turbines, generator and an exciter. The excitation system considered is IEEE type 1 with saturation. The auxiliary controls considered to damp the unstable subsynchronous modes of oscillations are Power System Stabilizer (PSS) and Static var Compensator (SVC). The different cases of power system stabilizer and reactive power controls are adapted to study the effectiveness of damping these unstable subsynchronous modes of oscillations.

K. P. Ashik, Ramesh S. Sharma
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2015, DOI: 10.4236/jmmce.2015.35044
Abstract: Natural fibres will take a major role in the emerging “green” economy based on energy efficiency, the use of renewable materials in polymer products, industrial processes that reduce carbon emissions and recyclable materials that minimize waste. Natural fibres are a kind of renewable resources, which have been renewed by nature and human ingenuity for thousands of years. They are also carbon neutral; they absorb the equal amount of carbon dioxide they produce. These fibers are completely renewable, environmental friendly, high specific strength, non-abrasive, low cost, and bio-degradability. Due to these characteristics, natural fibers have recently become attractive to researchers and scientists as an alternative method for fibers reinforced composites. This review paper summarized the history of natural fibers and its applications. Also, this paper focused on different properties of natural fibers (such as hemp, jute, bamboo and sisal) and its applications which were used to substitute glass fiber.

Open Journal of Soil Science (OJSS) , 2015, DOI: 10.4236/ojss.2015.512027
Abstract: Most Eritrean farmers do not adopt soil conservation measures and till even sloppy fields 2 - 4 times for planting sorghum (Sorghum bicolor L.) with a view to facilitate rainwater intake. Field experiments were conducted at Hamelmalo to optimize tillage and irrigation requirements of sorghum in loamy sand. Tillage treatments were conventional tillage (4 times) on existing slopes (CTf), conventional tillage on managed plots (terraced) with residue (CTm + R) and without residue (CTm - R), reduced tillage (single tillage 4 days after heavy rainfall) on managed plots with residue (RTm + R) and without residue (RTm - R) and no tillage (direct planting) on managed plots with residue (NTm + R) and without residue (NTm - R) randomized in four replications. Tillage in CTm and CTf was same. Experiment was repeated in year II along with a new experiment in split plot design with same tillage treatments in main plots and 4 irrigation treatments in subplots in 3 replications. Irrigation treatments were rainfed (I0), 70 mm irrigation at 50% depletion of soil moisture in CTm - R from 1 m profile after end of monsoon (I1), 70 mm irrigation 7 days after irrigation in I1 (I2), and 70 mm irrigation 7 days after irrigation in I2 (I3). Bulk density increased and infiltration rates decreased by harvesting due to tillage but changes were lower in residue plots of NT and RT than CT. Optimum soil moisture for emergence of sorghum was within 0.145 ± 0.002 m3 m-3 at which soil strength was well below critical level for root growth. Soil strength in tilled layer due to intermittent wetting and drying following planting exceeded 2000 k

Abstract: Kidney stone consists of various compounds. Mineral oxalate monohydrate and di-hydrate are the main constituent of kidney stones. However, the formation of calcium oxalate kidney stones is still not clearly understood. In this field of studies, several new hypotheses are created, which includes nucleation, reduction of nucleation, crystal growth and or aggregation of formation of different crystals such as oxalate monohydrate and oxalate di-hydrate. The effect of some urinary species such as ammonium oxalate, calcium, citrate, proteins and trace elements were reported by the author. The kidney stone constituents along with trace minerals are grown in silica gel medium (SMS) which provides the necessary growth simulation (in-vivo). In the artificial urinary stone growth process, growth parameters within the different chemical environments were carried out and reported for several urinary crystals such as CaHP, SrHP, SrMHP, BaHP, BaMHP and MgHP. In the present investigation, BaSrCrMHP (Barium Strontium Chromium Magnesium Hydrogen Phosphate) crystals are grown in different growth faces to attain the total nucleation reduction. Extension of this investigation, many characterization studies have been carried out and compared with reported results.
Spontaneous Hemopericardium Leading to Cardiac Tamponade in a Patient with Essential Thrombocythemia
Anand Deshmukh,Shanmuga P. Subbiah,Sakshi Malhotra,Pooja Deshmukh,Suman Pasupuleti,Syed Mohiuddin
Cardiology Research and Practice , 2011, DOI: 10.4061/2011/247814
Abstract: Acute cardiac tamponade requires urgent diagnosis and treatment. Spontaneous hemopericardium leading to cardiac tamponade as an initial manifestation of essential thrombocythemia (ET) has never been reported in the literature. We report a case of a 72-year-old Caucasian female who presented with spontaneous hemopericardium and tamponade requiring emergent pericardiocentesis. The patient was subsequently diagnosed to have ET. ET is characterized by elevated platelet counts that can lead to thrombosis but paradoxically it can also lead to a bleeding diathesis. Physicians should be aware of this complication so that timely life-saving measures can be taken if this complication arises.
Groundnut improvement: use of genetic and genomic tools
Pasupuleti Janila,S. N. Nigam,Manish K. Pandey,P. Nagesh,Rajeev K. Varshney
Frontiers in Plant Science , 2013, DOI: 10.3389/fpls.2013.00023
Abstract: Groundnut (Arachis hypogaea L.), a self-pollinated legume is an important crop cultivated in 24 million ha world over for extraction of edible oil and food uses. The kernels are rich in oil (48–50%) and protein (25–28%), and are source of several vitamins, minerals, antioxidants, biologically active polyphenols, flavonoids, and isoflavones. Improved varieties of groundnut with high yield potential were developed and released for cultivation world over. The improved varieties belong to different maturity durations and possess resistance to diseases, tolerance to drought, enhanced oil content, and improved quality traits for food uses. Conventional breeding procedures along with the tools for phenotyping were largely used in groundnut improvement programs. Mutations were used to induce variability and wide hybridization was attempted to tap variability from wild species. Low genetic variability has been a bottleneck for groundnut improvement. The vast potential of wild species, reservoir of new alleles remains under-utilized. Development of linkage maps of groundnut during the last decade was followed by identification of markers and quantitative trait loci for the target traits. Consequently, the last decade has witnessed the deployment of molecular breeding approaches to complement the ongoing groundnut improvement programs in USA, China, India, and Japan. The other potential advantages of molecular breeding are the feasibility to target multiple traits for improvement and provide tools to tap new alleles from wild species. The first groundnut variety developed through marker-assisted back-crossing is a root-knot nematode-resistant variety, NemaTAM in USA. The uptake of molecular breeding approaches in groundnut improvement programs by NARS partners in India and many African countries is slow or needs to be initiated in part due to inadequate infrastructure, high genotyping costs, and human capacities. Availability of draft genome sequence for diploid (AA and BB) and tetraploid, AABB genome species of Arachis in coming years is expected to bring low-cost genotyping to the groundnut community that will facilitate use of modern genetics and breeding approaches such as genome-wide association studies for trait mapping and genomic selection for crop improvement.
