On Soft gr-Closed sets in Soft Topological Spaces

The aim of this paper is to introduce soft pgr-closed sets in topological spaces which is defined over the universe of the given set with a fixed set of parameters. Further, we investigate its properties and its relationship with other soft closed sets

Some derivations among Logarithmic Space Bounded Counting Classes

In this paper we show derivations among logarithmic space bounded counting classes based on closure properties of $\#L$ that leads us to the result that $NL=C_=L\subseteq PL$.Comment: 3 page

VISITOR PREFERENCES AND VALUES FOR WATER-BASED RECREATION: A CASE STUDY OF THE OCALA NATIONAL FOREST

We used the open-ended contingent valuation method to elicit willingnes to pay (WTP) for day visitors and extended visitors on the Ocala National Forest (ONF), Florida. A Tobit model specification was applied to account for the issues involved with censored WTP bids. The results reveal that visitors would pay more for improved recreational facilities at the ONF. In particular, our estimates show that visitors would pay $1 million for basic facilities,$1.9 million for moderate improvements, and $2.5 million for more improvements.contingent valuation, Tobit analysis, water-based recreation, Resource /Energy Economics and Policy, Q23, Q26,

Variable Rate LPPT Based Droop Controlled Operation of Photovoltaic System for Microgrid Frequency Regulation

The objective of this thesis is to improve the frequency regulation of an islanded microgrid system consisting of photovoltaic (PV) system. Operating the PV system in Limited power point tracking (LPPT) mode gives provision for the application of droop control on the PV system active power, which in turn enhances the frequency regulation of the microgrid. LPPT is a control technique used for extracting the desired amount of power that may be less than the maximum available power from the PV system. Variable rate LPPT is the superior control technique among the available LPPT control techniques, which is employed in the work. The droop controller implemented in this thesis provides the required power reference command for the limited power operation of a PV system based on the deviation of bus frequency from its nominal value (50 Hz/60 Hz). A case study is presented to validate the effectiveness of the above-mentioned concept

Key Authentication Scheme-based on Discrete Logarithms and Chinese Remainder Theorem

Public key cryptosystems are secure only when the authenticity of the public key is assured. Shao proposeda new scheme to overcome the problems of the existing schemes, which suffers from two major drawbacks. Thefirst drawback is the availability of users’ passwords in plaintext format in key server which are prone to attacksby ill-minded users. The second one is depending on the key server blindly for certificate generation, withoutfurther verification by the user. To overcome these severe drawbacks, we proposed an improved key authenticationscheme based on Chinese remainder theorem and discrete logarithms. Our scheme allows the user to generate his/her certificate without the help of any trusted third party. This scheme is intended for online services, military anddefense applications to exchange keys securely.

An observational study to monitor cutaneous adverse drug reaction profile in Dermatology Department of tertiary care teaching hospital

Background: Incidence of cutaneous adverse drug reactions (CADRs) in developed countries is 1 to 3% and in developing countries, it is much higher i.e. 2 to 6%. 1 in 1000 hospitalized patients will develop severe cutaneous adverse reaction. Maculopapular rash represents majority of cutaneous drug reaction followed by urticaria. Most frequently elicited CADRs are associated with antimicrobials and NSAIDs. This study was designed to monitor Cutaneous adverse drug reaction profile of tertiary care teaching hospital.Methods: This is a prospective observational study of 6 months’ duration to monitor cutaneous adverse drug reactions in dermatology department of tertiary care teaching hospital. CADRs were analysed with respect to demographic details, suspected drugs and type of reaction. Causality assessment is by Naranjo algorithm. Data is represented in tables and graphs. Data is analyzed in Microsoft excel 2007.Results: Total 57 cases of cutaneous adverse drug reactions were reported. Among them, 57.9% were in males and 42.1% were in females. Majority of CADRs were due to antiretroviral drugs (38.5%) followed by antibacterial (28%) and antiepileptics (14%). Maculopapular rash is most common CADR (35%). Causality of 74% CADRs were probable according to Naranjo algorithm.Conclusions: CADRs are more commonly associated with antiretroviral therapy (ART), antibacterial drugs and antiepileptic drugs. In case of ART, antiepileptic drug and drugs used in chronic illness compliance plays a major role in the success of therapy. Adverse drug reactions lead to problem of non compliance and failure of therapy. Cutaneous adverse reactions like FDE heal with hyper pigmentation leads to cosmetic problem. Stevens Johnson syndrome (SJS) is life threatening that requires prompt withdrawal of drug and intensive medical management. Many drugs are available without prescription in India leading to problem of misdiagnosis of CADRs. So, data obtained from this study helps in proper diagnosis and treatment of CADRs
