Escherichia coli RecA protein pairs homologous DNA molecules to form paranemic joints when there is an absence of a free end in the region of homologous contact. Paranemic joints are a key intermediate in homologous recombination and are important in understanding the mechanism for a search of homology. The efficiency of paranemic joint formation depended on the length of homology and the topol...

Manufacturing and Testing techniques were investigated for the development of efficient joining of composite tubes. The stepped lap joining arrangements were studied. Finite element models were developed using ANSYS finite element code for predicting the stress distribution of the joint under the applied loads. Tubes made of graphite/epoxy were considered. The tubes were tested under both tensi...

Three mm thick plates of commercial pure copper were welded via friction stir welding method using a floating bobbin tool. The effect of different process variables such as the tool transverse speed and the tool rotation speed were examined in order to create a weld with the desired properties. A defect-free weld was obtained at a rotation speed of 1400 rpm and a transverse speed of 18 mm/min w...

We present a new approach to approximate joint diagonalization of a set of matrices. The main advantages of our method are computational efficiency and generality. The algorithm is based on the Frobeniusnorm formulation of the joint diagonalization problem, and addresses diagonalization with a general, non-orthogonal transformation. The iterative scheme of the algorithm inherits the key ideas f...

In this paper, a hierarchical cross-layer design approach is proposed to increase energy efficiency in ad hoc networks through joint adaptation of nodes’ transmitting powers and route selection. The design maintains the advantages of the classic OSI model, while accounting for the cross-coupling between layers, through information sharing. The proposed joint power control and routing algorithm ...

As previous reports have highlighted that temporomandibular joint dysfunction syndrome can occur during scuba diving due to the use of a diving mouthpiece, 74 divers of varied experience (62 male, 12 female) were asked to evaluate the efficiency of the mouthpiece for the ease of grip, insertion into the mouth, clearing of water, air sharing, comfort and overall efficiency. They also recorded th...

Very efficient still image compression methods exist today, but most of them are not fit for transmission on error prone channels. One example of state-of-the-art robust image coding is the use of wavelet compression followed by forward error correction (FEC), as proposed by Sherwood and Zeger, that gives high coding efficiency but suffers from the incomplete decoding problem. An alternative to...

Many developing countries are liberalizing their economies to allow higher equity participation by the foreign firms. We argue that the possibility of joint venture can reduce the number of technology transfers. Hence, joint venture can reduce the welfare of a host-country by creating higher market-concentration. However, higher profit generation under joint venture encourages the foreign firm ...

In this papera switching control strategy for robust stabilization of the 2nd-order non-holonornic 2-DOF SCARA robot Ft21)l is presented. The Ist joint is actuated by a direct drive motor, whereas the 2nd joint is equipped with a brake. The unactuated 2nd joint is controlled by non-collocated linearization and a PDcontroller. A stability region is den”ued and robustness is achieved by exploitin...

Abstract Joint reconstruction is a process in which the compressed and encrypted image can be reconstructed sequentially. This paper analyses various methods of joint reconstruction techniques and its performance. The main objective is to provide security through encryption and efficiency via compression. These are normally applicable in secure medical image sharing system. In this paper, Predi...
