Simulation of a mechanical system incorporating the biological control has drawn the fascination of researchers' interest in the research field of advanced prosthetic control and artificial intelligence. This paper generates the idea of modeling of a mechanical prosthetic arm via some heuristic applications of simulation techniques. The introductory part of the paper shows the clinical study of an upper limb amputated patient. Afterwards the experimental approach for measurement of different parameters for the prosthetic arm is described. Then the sets of open loop transfer functions for the study of mechanical prosthetic arm are developed. Optimum transfer functions were initiated in the later part of the paper and finally they are tuned by traditional tuning method as well as the genetic and swarm intelligence tuning algorithms for establishing better results and more efficiency in modeling. © 2012 IEEE.

This paper is based on the glimpse of modeling of a prosthetic eye by incorporating clinical study of a human eye and by attempting a proper interfacing technique between a prosthetic or artificial eye and human brain intelligence via integrated control approaches and with the help of simulation aspects. Specific result analysis has been carried out by generating an appropriate transfer function of linear concept. After the generation of transfer function model, the simulation approach is incorporated via stability analysis for designing of the prosthetic eye. Moreover, an attempt is taken on furnishing the hardware implementation of producing an ideal prosthetic eye which tends to be a pre-innovative work in the varied field of prosthesis and artificial intelligence. © 2011 IEEE.

This paper presents a cost-effective, low-power wireless real-time environment monitoring network for highly secure and reliable data transmission from potentially hazardous underground mines. ZigBee protocol based wireless monitoring system is developed that effectively monitors mines environment parameters such as temperature, humidity, concentration of gases like methane, CO2 etc. Wireless monitoring system is created through joining of several nodes and they are interfaced with miniature size sensors. The wireless sensor network is created through these sensor nodes which wirelessly transfer data to a master node. The sensor node consists of low power 8051 microcontroller core and low power transceiver integrated in a single on chip. Smaller size sensor node is suitably deployed as an attachment with miner's helmet. Sensor nodes help to collect real time data from underground mines and transmitted to the surface. Through use of sensor network analyzer tool, the analysis of encrypted data and online view of existing node network are also made. Data management software is developed to display and store those data online both in graphical and numerical forms.

The provision of blind quality assessment is an important requirement for modern multimedia and communication systems. Fragile watermarking techniques have been proposed earlier for this purpose. This paper proposes a novel approach which makes use of both fragile and robust watermarking techniques. The embedded fragile watermark is used to assess the degradation undergone by the transmitted images. Robust image features, on the other hand, are used to construct the reference watermark from the received image, for assessing the amount of degradation of the fragile watermark. Construction of the watermark from the image itself, dispenses with the need for embedding an extraneous watermark which must be made known to the user separately, a significant contribution of the present work in image quality assessment. Another contribution is the use of Singular Value Decomposition (SVD) for the extraction of the fragile watermark. The validity of the proposed approach is veri#ed through extensive simulations using different kinds of gray-scale and color images. © 2011 University of Zagreb.

Natural selection based on phenotypic traits may lead to genetic changes. To understand the relationship between phenotypic traits and gene expression profiles it is important to study the concordance between the two. In this work we have developed a simple procedure to find the differentially expressed (DE) genes across various tissues between phenotypes through linear correlation as well as non linear mutual information and polynomial regression between quantitative-trait and the gene expression profiles. Here we are making the use of mice gene expression data to find the differentially expressed genes between the male and female phenotypes exploring the dependency between the gene expression profiles of four tissues (brain, muscle, liver, adipose) and quantitative trait (weight). To prove the effectiveness of the method we have tested our results with a popular DE tool (DEGseq). In the results we have shown that mutual information based trait-specific DE genes are biologically more significant compared to the polynomial regression and linear correlative counterparts. © 2015 The Authors.

The topology of the ad hoc network has a significant impact on its performance. The dense topology has produce high interference and low capacity while the thinly scattered topology is Vulnerable to link failure. Some research work has been done on topology control in wireless networks. The existing topology control algorithms utilize either a purely centralized or purely distributed approach. In this work we have presented the traffic load analysis of the mobile node in the wireless network, by used of cluster concept. The wireless domain has been partitioned into different zones or clusters. Here we present analytically, the hops distance between random cluster heads. We have considered the minimum hops distance between the clusters and shown the traffic load at the gateway node, destination node. We considered that all the nodes randomly move. In this paper we have shown, how clustering affects on the performance with respect to throughput, delay, packet sent and packet received by simulation. © Springer-Verlag Berlin Heidelberg 2010.

Using a simple density-dependent finite-range effective interaction having Yukawa form, the density dependence of isoscalar and isovector effective masses is studied. The isovector effective mass is found to be different for different pairs of like and unlike nucleons. Using HVH theorem, the neutron-proton effective mass splitting is represented in terms of symmetry energy and its density slope. It is again observed that the neutron-proton effective mass splitting has got a positive value when isoscalar effective mass is greater than the isovector effective mass and has a negative value for the opposite case. Furthermore, the neutron-proton effective mass splitting is found to have a linear dependence on asymmetry β. The second-order symmetry potential has a vital role in the determination of density slope of symmetry energy but it does not have any contribution on neutron-proton effective mass splitting. The finite-range effective interaction is compared with the SLy2, SKM, f−, f0, and f+ forms of interactions. © 2015, Pleiades Publishing, Ltd.

A phenomenological momentum dependent interaction (MDI) is considered to describe the equation of state (EOS) for isospin asymmetric nuclear matter (ANM), where the density dependence of the nuclear symmetry is the basic input. In this interaction, the symmetry energy shows soft dependence of density. Within the nonrelativistic mean field approach we calculate the nuclear matter fourth-order symmetry energy E sym, 4(ρ). Our result shows that the value of E sym, 4(ρ) at normal nuclear matter density ρ 0 ( = 0.161 fm -3) is less than 1 MeV conforming the empirical parabolic approximation to the EOS of ANM at ρ 0. Then the higher-order effects of the isospin asymmetry on the saturation density ρ sat(β), binding energy per nucleon K sat(β) and isobaric incompressibility K sat(β) of ANM is being studied, where β = ρn-ρp/ρ is the isospin asymmetry. We have found that the fourth-order isospin asymmetry β cannot be neglected, while calculating these quantities. Hence the second-order K sat, 2 parameter basically characterizes the isospin dependence of the incompressibility of ANM at saturation density. © 2012 World Scientific Publishing Company.

Using a density dependent finite-range effective interaction of Yukawa form the nuclear mean field in asymmetric nuclear matter is expanded in terms of power series of asymmetry β (=ρn-ρpρ) as uτ(k, ρ, β) = u0(k, ρ) ± u sym,1(k, ρ)β + u sym,2(ρ)β2. The behavior of nuclear symmetry potential u sym,1(k, ρ) around the Fermi momentum k f is found to be connected to the density dependence of symmetry energy E sym(ρ) and nucleon effective mass m0*m (k = k f, ρ) in symmetric nuclear matter. Two different trends of momentum dependence for nuclear symmetry potential is observed depending on the choice of strength parameters of exchange interaction, but at Fermi momentum it is found to be independent of the choice of parameters. The nuclear symmetry energy E sym(ρ) and its slope L(ρ) are expressed analytically in terms of nuclear mean field in isospin asymmetric nuclear matter using the same interaction. We find that the second order nuclear symmetry potential u sym,2(ρ) cannot be neglected while calculating the density slope of symmetry energy L(ρ) as well as the nuclear mean field in extremely neutron (proton) rich nuclear matter. © 2013 Elsevier B.V.

This paper is based on the glimpse of the clinical studies and its applications for starting different characteristic interpretation of Electromyography (EMG) signal. The paper presents the biological and the clinical properties of different human muscles and their movements. Strong and precise information about both active and inactive conditions of the skeletal muscles i.e propius muscle, biceps muscle, triceps muscle, deltoid muscle, etc. are shown in a tabular format. In real world, the elimination of anomaly of noisy EMG signal and its proper implementation is very difficult work. An attempt is taken on accomplishing an efficient and discretized knowledge based database of EMG interpretation and by the help of this database we just took a footstep to generate an actuator for the EMG interpretation to facilitate the modeling of dexterous prosthetic arm. © 2011 IEEE.
