Changing Pragmatics of The Indian Pharmaceutical Industry In The Pre and Post TRIPS Period
Ravi Kiran
International Journal of Business and Management , 2009, DOI: 10.5539/ijbm.v4n9p206
Abstract: The agreement on Trade-Related Aspects of Intellectual Property-Rights (TRIPS) is an international treaty by the world trade organisation (WTO) which sets down minimum standards for most form of intellectual property (IP) regulation within all member countries of the world trade organization. As a result of TRIPS the Pharmaceutical industry has witnessed significant changes. Against this background, the paper tries to study the Post TRIPS Patenting, Exports and R& D Scenario in Pharmaceutical Industry of India. The study uses the primary as well as secondary data to the changes in the pharmaceutical industry in post-TRIPS period. There has been a paradigm shift in the policies and programs governing Indian pharmaceutical industry. The results of the study highlight that the new patent regime has encouraged innovation and greater investment in R&D. Patents are the most efficacious and indispensable tool to secure strategic competitive advantage in the market. The impact of TRIPS compliance is becoming increasingly visible, on the pharmaceutical industry in India. Keywords: Trade-Related Aspects of intellectual property-Rights, General Agreement on Trade and Tariff, World Trade Organisation
Anonymous Processing of Query in Road Networks
Ravi Kiran
International Journal of Computer and Distributed System , 2012,
Abstract: The increasing availability of location-aware mobile devices has given rise to a flurry of location-based services (LBS). Due to the nature of spatial queries, an LBS needs the user position in order to process her requests. On the other hand, revealing exact user locations to a (potentially untrusted) LBS may pinpoint their identities and breach their privacy. To address this issue, spatial anonymity techniques obfuscate user locations, forwarding to the LBS a sufficiently large region instead.Existing methods explicitly target processing in the Euclidean space, and do not apply when proximity to the users is defined according to network distance (e.g., driving time through the roads of a city). In this paper, we propose a framework for anonymous query processing in road networks. We design location obfuscation techniques that (i) provide anonymous LBS access to the users, and (ii) allow efficient queryprocessing at the LBS side. Our techniques exploit existing networkdatabase infrastructure, requiring no specialized storage schemes orfunctionalities. We experimentally compare alternative designs in real road networks and demonstrate the effectiveness of our techniques.
MODELING ORDINARY DIFFERENTIAL EQUATIONS IN MATLAB SIMULINK
Ravi Kiran Maddali
Indian Journal of Computer Science and Engineering , 2012,
Abstract: Ordinary differential equations (ODEs) play a vital role in engineering problems. They are used to model continuous dynamical systems as initial and boundary value problems. There are several analytical and numerical methods to solve ODEs. Various numerical methods such as Euler’s method, Runge-Kutta method, etc are so popular in solving these ODEs. MATLAB, the language of technical computation developed by mathworks, is gaining importance both in academic and industry as powerful modeling software. SIMULINK ,is a tool in MATLAB for simulating both continuous and discrete dynamical systems. In SIMULINK , we can simulate the behavior of a system by representing the system in terms of a block diagram with interconnections between the blocks and there by simulate its behavior over certain period of time. The study of ODEs has variety of applications in disciplines like aerospace, electronics, communication, medicine, finance, economics, and physiology. In this article, the technique of modeling and simulation of first order differential equations in SIMULINK, which can be further extended to higher order systems, is discussed.
An Analysis of Investor’s Risk Perception towards Mutual Funds Services
Nidhi Walia,Ravi Kiran
International Journal of Business and Management , 2009, DOI: 10.5539/ijbm.v4n5p106
Abstract: Financial markets are constantly becoming more efficient by providing more promising solutions to the investors. Being a part of financial markets although mutual funds industry is responding very fast by understanding the dynamics of investor’s perception towards rewards, still they are continuously following this race in their endeavor to differentiate their products responding to sudden changes in the economy. Thus, it is high time to understand and analyze investor’s perception and expectations, and unveil some extremely valuable information to support financial decision making of mutual funds. Financial markets are becoming more exhaustive with financial products seeking new innovations and to some extent innovations are also visible in designing mutual funds portfolio but these changes need alignment in accordance with investor’s expectations. Thus, it has become imperative to study mutual funds from a different angle, i.e, to focus on investor’s expectations and uncover the unidentified parameters that account for their dissatisfaction. Present research proposes to identify critical gaps in the existing framework for mutual funds and further extend it to understand realizing the need of redesigning existing mutual fund services by acknowledging Investor Oriented Service Quality Arrangements (IOSQA) in order to comprehend investor’s behavior while introducing any financial innovations.
Tuberculous Arthritis of Knee Presenting as Bakers Cyst: A Case Report  [PDF]
Tummala Venkata Suresh Babu, Kopuri Ravi Kiran, Kora Deepti
International Journal of Clinical Medicine (IJCM) , 2014, DOI: 10.4236/ijcm.2014.56048
Abstract:

Tuberculosis (TB) is no longer confined to undeveloped or developing nations. Today, one third of world’s population suffers from tuberculosis. Tuberculosis (TB) of the musculoskeletal system is an uncommon infection caused by tuberculous bacilli and constitutes 1%-5% of all forms of TB. 30% of skeletal TB involves the joints, the knee being the third most commonly affected after the spine and the hip. Knee tuberculosis commonly presents as synovitis or arthritis. Baker’s cyst is a rather rare complication of knee joint tuberculosis. We report a case of a 50-year-old man with tuberculous arthritis of the right knee who presented to us as baker’s cyst.

Concurrent Nimotuzumab with Radiation Therapy in Locally Advanced Cancers of Oropharynx and Hypopharynx: A Review of 6 Cases  [PDF]
B. Ravi Shankar, Poojar Kiran, B. V. Madhavi, E. Vijay
Journal of Cancer Therapy (JCT) , 2015, DOI: 10.4236/jct.2015.64042
Abstract:

Background: The prevalence of head and neck cancers in the world is around 57% and predominantly occurs in Asian countries. It accounts for 30% of all cancers in India. The cure rate of locally advanced squamous cell carcinoma of the head and neck (SCCHN) has only 30% - 60% even after combined therapeutic approaches. Epidermal Growth Factor Receptor (EGFR) antagonists are the most researched targets in the management of head and neck cancers. Claims at superior tumor control and additional survival benefit without any added toxicity make it an attractive option. With this case series we intend to see how nimotuzumab, a humanized monoclonal antibody, fares in difficult cases of head and neck cancers. Case Description: In this case series, total six patients of locally advanced cancer of head and neck region were treated weekly using cisplatin and nimotuzumab concurrently with radiation therapy (RT) for 6 - 7 weeks. Depending upon the disease stage as well as the general condition of the patient, different dose cycles and radiation doses were tailored. Patients were monitored for regular physical examinations and hematological tests followed by pre and post treatment computed tomography (CT) scans, Fludeoxyglucose positive emission tomography (FDG PET-CT) scans, and histopathology. All patients were assessed for toxicities and managed consequently. After completion of radiation and follow-up, 6 weeks later post treatment CT scans were carried out. Conclusion: This case series shows that combination of chemoradiation with nimotuzumab achieved good response rates with no evidence of residual disease/disease progression on follow-up. The patients’ tolerability with combination therapy was good and toxicity was acceptable. Nimotuzumab was found beneficial in combination with chemoradiation for locally advanced head and neck cancers.

Analyzing structural characteristics of object category representations from their semantic-part distributions
Ravi Kiran Sarvadevabhatla,Venkatesh Babu R
Computer Science , 2015,
Abstract: Studies from neuroscience show that part-mapping computations are employed by human visual system in the process of object recognition. In this work, we present an approach for analyzing semantic-part characteristics of object category representations. For our experiments, we use category-epitome, a recently proposed sketch-based spatial representation for objects. To enable part-importance analysis, we first obtain semantic-part annotations of hand-drawn sketches originally used to construct the corresponding epitomes. We then examine the extent to which the semantic-parts are present in the epitomes of a category and visualize the relative importance of parts as a word cloud. Finally, we show how such word cloud visualizations provide an intuitive understanding of category-level structural trends that exist in the category-epitome object representations.
Vulnerability Management for an Enterprise Resource Planning System
Shivani Goel,Ravi Kiran,Deepak Garg
Computer Science , 2012, DOI: 10.5120/8409-2043
Abstract: Enterprise resource planning (ERP) systems are commonly used in technical educational institutions(TEIs). ERP systems should continue providing services to its users irrespective of the level of failure. There could be many types of failures in the ERP systems. There are different types of measures or characteristics that can be defined for ERP systems to handle the levels of failure. Here in this paper, various types of failure levels are identified along with various characteristics which are concerned with those failures. The relation between all these is summarized. The disruptions causing vulnerabilities in TEIs are identified .A vulnerability management cycle has been suggested along with many commercial and open source vulnerability management tools. The paper also highlights the importance of resiliency in ERP systems in TEIs.
Category-Epitomes : Discriminatively Minimalist Representations for Object Categories
Ravi Kiran Sarvadevabhatla,R. Venkatesh Babu
Computer Science , 2015,
Abstract: Freehand line sketches are an interesting and unique form of visual representation. Typically, such sketches are studied and utilized as an end product of the sketching process. However, we have found it instructive to study the sketches as sequentially accumulated composition of drawing strokes added over time. Studying sketches in this manner has enabled us to create novel sparse yet discriminative sketch-based representations for object categories which we term category-epitomes. Our procedure for obtaining these epitomes concurrently provides a natural measure for quantifying the sparseness underlying the original sketch, which we term epitome-score. We construct and analyze category-epitomes and epitome-scores for freehand sketches belonging to various object categories. Our analysis provides a novel viewpoint for studying the semantic nature of object categories.
