An Intelligent Software Workflow Process Design for Location Management on Mobile Devices
N. Mallikharjuna Rao
Computer Science , 2012,
Abstract: Advances in the technologies of networking, wireless communication and trimness of computers lead to the rapid development in mobile communication infrastructure, and have drastically changed information processing on mobile devices. Users carrying portable devices can freely move around, while still connected to the network. This provides flexibility in accessing information anywhere at any time. For improving more flexibility on mobile device, the new challenges in designing software systems for mobile networks include location and mobility management, channel allocation, power saving and security. In this paper, we are proposing intelligent software tool for software design on mobile devices to fulfill the new challenges on mobile location and mobility management. In this study, the proposed Business Process Redesign (BPR) concept is aims at an extension of the capabilities of an existing, widely used process modeling tool in industry with 'Intelligent' capabilities to suggest favorable alternatives to an existing software workflow design for improving flexibilities on mobile devices.
An Intelligent Location Management approaches in GSM Mobile Network
N. Mallikharjuna Rao
Computer Science , 2012,
Abstract: Location management refers to the problem of updating and searching the current location of mobile nodes in a wireless network. To make it efficient, the sum of update costs of location database must be minimized. Previous work relying on fixed location databases is unable to fully exploit the knowledge of user mobility patterns in the system so as to achieve this minimization. The study presents an intelligent location management approach which has interacts between intelligent information system and knowledge-base technologies, so we can dynamically change the user patterns and reduce the transition between the VLR and HLR. The study provides algorithms are ability to handle location registration and call delivery

N. Mallikharjuna Rao,C. Sasidhar,V. Sathyendra Kumar
Computer Science , 2012,
Abstract: Cloud computing is the new technology that has various advantages and it is an adoptable technology in this present scenario. The main advantage of the cloud computing is that this technology reduces the cost effectiveness for the implementation of the Hardware, software and License for all. This is the better peak time to analyze the cloud and its implementation and better use it for the development of the quality and low cost education for all over the world. In this paper, we discuss how to influence on cloud computing and influence on this technology to take education to a wider mass of students over the country. We believe cloud computing will surely improve the current system of education and improve quality at an affordable cost.
Effect of BaTiO3 Nanoparticle on Electro-Optical Properties of Polymer Dispersed Liquid Crystal Displays  [PDF]
Mallikharjuna Rao Darla, Sriharsha Hegde, Soney Varghese
Journal of Crystallization Process and Technology (JCPT) , 2014, DOI: 10.4236/jcpt.2014.41008

Ferro nematic suspensions are the prominent materials to enhance the electro optical performance of liquid crystal displays. Electro optical properties of polymer dispersed liquid crystal (PDLC) display with the introduction of Barium Titanate nanoparticles have been investigated in this article and it is shown that there is a considerable enhancement in electro-optical response of the displays. The nanoparticles lower the switch-on electric field and thereby increase the optical transmission at certain voltages of the displays. The electro-optical characteristics of the PDLC cells were investigated with a He-Ne laser followed by MatLab calculations.

Recovery of Ilmenite and Other Heavy Minerals from Teri Sands (Red Sands) of Tamil Nadu, India  [PDF]
N. Babu, N. Vasumathi, R. Bhima Rao
Journal of Minerals and Materials Characterization and Engineering (JMMCE) , 2009, DOI: 10.4236/jmmce.2009.82013
Abstract: The red sand which is known as Teri sand in Tamil Nadu consists of 5.5% Total Heavy Minerals (THM) out of which 3.7% is ilmenite. The other minerals, zircon, sillimanite and garnet are in the order of abundance identified. On processing this feed to recover ilmenite by using spirals followed by dry high intensity magnetic separator and high tension separator, the ilmenite concentrate obtained contains 99.1% ilmenite with 3.5% yield and 94% recovery. The other heavy minerals, including zircon (53.3%) and sillimanite (31.7%), could be further processed for recovery of individual mineral of zircon and sillimanite by judicious combination of gravity and flotation processes.
Development and Validation of Stability Indicating HPLC Method for Simultaneous Estimation of Amoxicillin and Clavulanic Acid in Injection  [PDF]
Durga Mallikarjuna Rao Tippa, N. Singh
American Journal of Analytical Chemistry (AJAC) , 2010, DOI: 10.4236/ajac.2010.13013
Abstract: A simple, fast, precise, accurate and rugged stability indicating high performance liquid chromatography (HPLC) method has been developed for simultaneous estimation of Amoxicillin and Clavulanic acid from injectable dosage form. The stability indicating capability of the method was proven by subjecting the drugs to stress conditions as per ICH recommended test conditions such as alkaline and acid hydrolysis, oxidation, photolysis, thermal degradation and resolution of the degradation products formed therein. The separation was obtained using a mobile phase composition at a ratio of 95:5 (v/v) of pH 5.0 buffer and methanol on Inertsil C18 column (250 × 4.0 mm, 4 μm) with UV detection at 220 nm at a flow rate of 1 ml/minute. The photodiode array detector was used for stress studies. The order of elution of peaks was Clavulanic acid followed by Amoxicillin. The linear calibration range was found to be 79.51 to 315.32 μg/ml for Amoxicillin and 17.82 to 67.90 μg/ml for Clavulanic acid. The Amoxicillin and Clavulanic acid were found to be stable in solution up to 24 hours. The method validation data showed excellent results for precision, linearity, specificity, limit of detection, limit of quantification and robustness. The present method can be successfully used for routine quality control and stability studies.
Integrated Studies for Mapping of Uranium Mineralization in Northern Cape Province of South Africa  [PDF]
Bijay Kumar Mishra, N. Sulekha Rao
Natural Science (NS) , 2015, DOI: 10.4236/ns.2015.78043
Abstract: Globally, there has been an ever increasing demand for uranium. This generates the need to adopt unique methodologies in order to explore the mineral to its full extent. This paper highlights an integrated approach that is adopted to explore uranium occurrences in the Northern Cape Province of South Africa. The study area is located at Springbok of Namaqualand Region. Most of the area is dominated by smooth outcrops formed by “Woolsack” mode of weathering and is characterized by pinkish fine-grained concordia granites of fair size forming the hilly terrains. These granites were intruded by quartz and pegmatite veins which host uranium and associated ores. As part of the integrated approach, remote sensing, geological, geophysical and geochemical studies were carried out in the hilly terrain area of approximately 15 sq km area. Spectral analysis was carried out using ASTER and QuickBird imageries to identify the zones of mineralisation. Band combinations of R (5/8) G (4/6) B (6/7) revealed the occurrence of uranium ore in the study area. Remote sensing and geological studies prioritized area for geophysical and geochemical studies. Ground magnetic analytical signal maps helped in deciphering the sub-surface structural anomalies. Magnetic and radiometric studies revealed that the uranium mineralization was localized along the structural features which were of sub-surficial origin. Geochemical sampling helped to identify the zones with high uranium ore concentration along the structural trend of the area. Further, geochemical data analysis also strongly supported the geophysical data and showed that the host rocks contain mineable quantities of uranium. The above integrated study indicates that uranium mineralisation in this particular area is structurally controlled which is nothing but the manifestations of geological features such as faults, fissures, and joints. The study helped to identify two blocks covering 85 Ha and 174 Ha of area and 7 drilling locations were proposed for exploratory drilling.
