The process of retrieving desired images from a large collection is widely used in applications of computer vision. In order to improve the retrieval performance an efficient and accurate system is required. Retrieving images based on the content i.e. color, texture, shape etc is called content based image retrieval (CBIR). The content is actually

The significance for measuring the accurate flow rate of gases in pipelines has been ever-increasing in the industrialized regions. There arises the need for gross measurements of gas-flow at some points while more accurate measurements of gas-flow are needed at some other points in an industry. Moreover, as the industry develops it undergoes chang

Due to the growth of computer networks, the word routing protocol has spread with a notice able speed making a huge impact through the world of networking. Various types of routing protocols have been used in lots of fields; each field uses the protocols that suit its needs with consideration to several metrics such as power and bandwidth consumpti

In this paper we present the experimental implementation of dynamic spectrum access (DSA) algorithm using universal software radio peripheral (USRP) and GNU Radio. The setup contains two primary users and two cognitive radios or secondary users. One primary user is fixed and the other is allowed to change its position randomly. Depending upon the p

In this paper we have investigated the security of different variants the golden cryptography, and showed that all the variants of the cryptosystem are not secure against chosen-plaintext attack.Int.

Introduction: The glenohumeral joint is one with the greatest mobility and intimate contact between the articular surfaces of the humeral head and glenoid labrum contributes to its stability. Patients with recurrent dislocations have bone deficits in one or both of these surfaces, due to the presence of a Bankart lesion or an engaging Hill-Sachs le

The bulk of the Earth's biosphere is cold (e.g. 90% of the ocean's waters are ≤ 5°C), sustaining a broad diversity of microbial life. The permanently cold environments vary from the deep ocean to alpine reaches and to polar regions. Commensurate with the extent and diversity of the ecosystems that harbour psychrophilic life, the function

Many studies have been done on the non-native speakers’ pragmalinguistic and politeness related interactions by contrasting the data with native speakers’ discourse, for instance in areas of expression of apologies (Cohen & Olshtain, 1981) and requests (Blum-Kulka, 1982). What these studies show is that learning a second language does not o

This paper summarises the research carried out to develop Finite Element (FE) modelling and predictive techniques for damage, fracture, fatigue and fretting fatigue problems. A damage model is developed based on Continuum Damage Mechanics and integrated within FE code. It is then used to predict the number of cycles to crack initiation in adhesivel

Our knowledge about a product, process or a system in the scientific and engineering disciplines is often obtained from experimentation. Experiments can discover many unexpected things and highlighted issues for further detailed study. The emerging of advanced products and processes are changing rapidly, customers are more demanding and product lif
