General-purpose image filters lack the flexibility and adaptability of un-modeled noise types. On the contrary, evolutionary algorithm based filter architectures seem to be very promising due to their capability of providing solutions to hard design problems. Through this novel approach, it is made possible to have an image filter that can employ a(More)
OBJECTIVE The anal sex among heterosexual couples is on the rise as reported in many scientific studies. Considering that unprotected anal sex has higher risk of human immunodeficiency virus (HIV) transmission than the vaginal sex, we undertook a study to understand the anal sex practices among Female Sex Workers (FSW). MATERIALS AND METHODS The study was(More)
— This paper is an original philosophy of analyzing the importance of fuzzy logic based intelligent concepts in the design of the temperature process controller for an injection mould machine. An injection mould machine is a basic requirement of every plastic, rubber etc.., process industries to mould the items to the desired shapes by the application of(More)
With the increasing cost of maintaining IT centers, organizations are looking into outsourcing thier storage and computational needs to a cloud server. However, such outsourcing has also raised the more serious issue of data privacy. In this paper, we summarize our work in privacy-preserving data outsourcing. In particular, we discuss the issue of employing(More)
Papers submitted will be reviewed and evaluated based on originality, technical quality and relevance to the conference. The paper length of 6 pages is encouraged and a upper limit of 10 pages, including figures, tables and references shall be enforced. The format of the papers should confirm to the ACM guidelines (option 2) available at The Computer(More)
The design of an ultra low voltage, low power high speed 8 channel Analog multiplexer in 180nm CMOS technology is presented. A modified transmission gate using a dynamic threshold voltage MOSFET (DTMOS) is employed in the design. The design is optimized with respect to critical requirements like short switching time, low power dissipation, good linearity(More)
A compact two element MIMO (Multiple Input Multiple Output) system is proposed using a multi slot patch antenna employing polarization diversity. The proposed MIMO system offers improved bandwidth, return loss and isolation characteristics. The system resonates at 5.35GHz and 5.81GHz frequencies for VSWR≤2, which can be used for 4G & WiMAX applications. The(More)
Reconfigurable hardware based image enhancement technique when compared to the conventional method has an improved image quality even under adverse conditions such as contrast reversal and intensity gradients, angular uncertainties, blur caused by changes in depth field, scale changes, partial obliteration or missing features. In addition, parallel(More)
With the increasing cost of maintaining IT centers, there is a trend among organizations to outsource data management functions to a third-party service provider to reduce storage and computational cost. However, this opens the door for privacy violations. Existing approaches for protecting data confidentiality are based on encryption or a combination of(More)
