In this paper, a novel technique is developed by hybridizing Bacterial Foraging Optimization technique in conjunction with Particle Swarm Optimization and is applied to the expressions developed by M.Kara to calculate accurately the desired resonant frequency of rectangular microstrip antenna of any dimension and of any substrate thickness.
Breast cancer is often diagnosed at its early stage as a non-palpable suspicious mass on a mammogram that may be cancerous at a later stage. Masses can be seen in both mediolateral and craniocaudal mammographic views. Masses with diameters less than 1 cm are generally benign, while those with diameters above 2 cm require further investigation. This paper… (More)
In this paper area efficient and cost effective techniques for design of pulse shaping filter have been presented to improve the computational and implementation complexity. Pulse shaping filters have been designed and implemented by using Raised cosine filter, Nyquist filter and optimized half band filters for software defined radio (SDR) based wireless… (More)
This paper presents fusion of Bacterial Foraging with parameter free Particle Swarm Optimization (HBF-pfPSO). The proposed technique is used to enhance quality of global optima of multimodal functions. The authors propose two major modifications in Bacterial Foraging Optimization (BFO). Firstly, all bacteria position and direction are updated after all… (More)
Minute calcium deposits that appear as bright spots on mammograms are known as microcalcifications. Calcifications in ducts and lobules are common markers of malignancy; therefore its detection plays a vital role in early detection of breast cancer. This paper proposes a novel framework for edge detection of microcalcifications using a combination of… (More)
In this paper an optimized hardware co-simulation approach is presented to design & implement GSM based digital down convertor for Software Defined Radios. The proposed DDC is implemented using optimal equiripple technique to reduce the resource requirement. A computationally efficient polyphase decomposition structure is used to improve the hardware… (More)
