This paper propose a new generation of antenna that applies Metamaterial properties at ground Plane. Paper also analyzed the performance of Microstrip Patch Antenna with and without using the Metamaterial structure. The works mainly include Metamaterial as Defected ground plane. All antenna parameters such as Return Loss, Gain, VSWR and Band width were measured. The main focus of this paper was...

In this paper, a dual band planar inverted F antenna (PIFA) has been investigated for cooperative onand off-body communications. Free space and on-body performance parameters like return loss, bandwidth, radiation pattern and efficiency of this antenna are shown and investigated. The onand off-body radio propagation channel performance at 2.45 GHz and 1.9 GHz have been investigated, respectivel...

Heterogeneity in Schooling Rates of Return This paper relaxes the assumption of homogeneous rates of return to schooling by employing nonparametric kernel regression. This approach allows us to examine the differences in rates of return to education both across and within groups. Similar to previous studies we find that on average blacks have higher returns to education than whites, natives hav...

Face recognition is an important area of research with many applications, including biometric security and searching face databases. This article describes an approach to recognize faces using eigenbands, which aim to capture the best features from facial characteristics. Faces are divided in vertical and horizontal hands. From each hand is extracted features using standard-PCA. Results show th...

This paper discusses the impact of collection cost structure on the optimal reverse channel choice in decentralized uncoordinated supply chains. Using collection cost functions that capture collection rate and collection volume dependency, we show that the optimal reverse channel choice is driven by how the cost structure moderates the manufacturer’s ability to shape the retailer’s sales and co...

In this paper we have analysed and designed a rectangular microstrip antenna. We analyzed micro strip antenna in IE3D by finite moment of method. In this paper we have compare and analyzed the micro strip antenna in infinite ground plane having dimension length, L = 700mil & width, W=800mil to the micro strip antenna in finite ground plane having dimension length, L = 1468mil & width, W=1568mil...

A concept (or signature) describes the interface of a set of abstract types by listing the operations that should be supported for those types. When implementing a generic operation, such as sorting, we may then specify requirements such as “elements must be comparable” by requiring that the element type models the Comparable concept. We may also use axioms to describe behaviour that should be ...

In this paper we propose a new way to combine classifiers trained and diverged by NCL that leads to superior results in compare with averaging and DTs methods alone. In the proposed method after training classifiers by NCL, DTs and averaging are employed independently to combine them and then the outputs are combined again by averaging. For the second level combination, support vectors are scal...

Supply chain companies are one of the most important elements of the economy of each country. These companies play an important role in the expansion and activities of other companies through the provision of capital, customers, credit and even raw materials and technology. Therefore, the main goal of this research was to examine the impact of contagion of return and volatility in the return of...

markowitz, in his portfolio selection theory, stated that investors select their portfolios according to two criteria of risk and return. accordingly, he presented his mathematical model. one of the criticisms of this model is that while investors, practically, consider different criteria in forming their portfolios, it only considers the return mean and return standard deviation. liquidity is ...
