    Get PDF
    Modern technology has changed human life by making it faster and easier. Technology innovation emerged as source of competitive strength and can achieve success through new innovation. ATM plays vital role in banking industry by providing all necessary banking facilities in easy and handy way to their customers at their doorstep. As Kurdistan is growing economy, therefore to assess perception and expectation of ATM customers, 315 respondents from different places of Kurdistan region were taken into consideration. This study is based on personal approach and observation. Structured questionnaire administered after taking opinion and modification by banking personal, customer discussion and review of literatures. For the convenience of respondents Likert measurement scales was used. To identify most service quality dimensions in connection with overall customer satisfaction; reliability test, descriptive analysis, correlation and coefficient and regression analysis test and ANOVA tests are done through SPSS 25.0. At the end it is concluded that most of factors are positively, significantly correlated with overall customer satisfaction. Based on personal discussion with customers and bank officials’ and literature reviews, recommendations are mentioned at the end

    Embedded Wireless Based Communications in Oilfield & Providing Security System

    The area of the oilfield is much wider. Oil exhauster continuous working for 24 hours. As the problem of petroleum being stolen, transmission line being stolen, and transformer being stolen exists which requires the strong secures management system. With Consideration of the objective condition restriction of geographical environment, the implementation of safe management for oilfield is very difficult. We overcome these difficulties, which comes from geographical environment. The cost is not only high if the fiber cable would be lay between working station in the several tens of square kilometers, but also need to put into a lot of human and material resources with line maintenance and guard against theft. It is a perfect scheme that remote wireless monitoring and control system is established. The system is required to manage the data received from the various site and providing the security by managing and providing automatic controlling structure

    Data Security and Access Control Mechanisms in Cloud: A Review

    Get PDF
    Cloud computing is a computing technology or information technology architecture used by organization or individuals. It launches data storage and interactive paradigm with some advantages like on-demand self-services, ubiquitous network access. Due to popularity of cloud services, security and privacy becomes major issue. This paper addresses study of privacy preservation issues and also provides an idea to how to overcome the issues. Also it provides a brief survey on various Robust Access Privilege Control mechanism used for providing privacy in cloud storage

    Robust Multiple Authority and ABE for Access Control in Cloud Computing

    Get PDF
    Data access control is a challenging issue in public cloud storage systems. Ciphertext-Policy Attribute-Based Encryption (CP-ABE) has been adopted as a promising technique to provide flexible, fine-grained and secure data access control for cloud storage with honest-but-curious cloud servers. However, in the existing CP-ABE schemes, the single attribute authority must execute the time-consuming user legitimacy verification and secret key distribution, and hence it results in a single-point performance bottleneck when a CP-ABE scheme is adopted in a large-scale cloud storage system. Users may be stuck in the waiting queue for a long period to obtain their secret keys, thereby resulting in low-efficiency of the system. Although multi authority access control schemes have been proposed, these schemes still cannot overcome the drawbacks of single-point bottleneck and low efficiency, due to the fact that each of the authorities still independently manages a disjoint attribute set. In this paper we propose a system that improves the approach of CP-ABE from text based asymmetric to Image based symmetric approach for faster encryption as well as access to data. We also propose a multiple access policy generation for single user where we will be able to implement one to many and many to many methodology

    A new, simple, sensitive, selective, precise and robust high-performance thin-layer chromatographic (HPTLC) method for analysis of stigmasterol was developed and validated for the determination of stigmasterol in different extracts. A new, simple, sensitive, selective, precise and robust high-performance thin-layer chromatographic (HPTLC) method for analysis of stigmasterol was developed and validated for the determination of stigmasterol in different extracts. Analysis of stigmasterol was performed on TLC aluminium plates pre-coated with silica gel 60F-254 as the stationary phase. Linear ascending development was carried out in twin trough glass chamber saturated with mobile phase consisting of Hexane : Acetone (8:2 v/v) at room temperature. (25 °C ± 2 °C) Camag TLC scanner III was used for spectrodensitometric scanning and analysis in absorbance mode at 490nm. The system was found to give compact spots for stigmasterol. (Rf value of 0.44 ± 0.02) The linear regression analysis data for the calibration plots showed good linear relationship with r2 =0.9997 ± 0.0002 in the concentration range 200-1200 ng spot−1 with respect to peak area. According to the International Conference on Harmonization (ICH) guidelines the method was validated for precision, recovery and robustness. Statistical analysis of the data showed that the method is reproducible and selective for the estimation of stigmasterol. Keywords: Tagetes erecta, Capsicum annuum, stigmasterol, HPTLC, method validatio

    SELF DOUBLE EMULSIFYING DRUG DELIVERY SYSTEM (SDEDDS): A REVIEW

    Get PDF
    Self emulsifying drug delivery systems (SEDDS) are well known for its potential to improve the aqueous solubility and oral absorption of lipophilic drugs. Self double-emulsifying drug delivery system (SDEDDS) are basically used for drugs having low solubility in water, but its potential application for the drugs defined as “high solubility low permeability class†or a biopharmaceutical classification system [BCS] class III drug is appreciable, in which gastrointestinal permeation is the rate controlling step in the absorption process. The most important factor affecting the oral absorption of a drug, besides dissolution, is the permeability of the drug across the gastrointestinal lining. Improving permeability may, therefore, potentially improve the bioavailability of a drug. In this review we discuss the preparation, stability, formulation and characterization of SDEDDS.   Key Words: Multiple emulsion, self emulsifying, Protein peptide drug delivery, High soluble poorly permeable drugs
