Distributed computer systems of microcontrollers with environmental sensors, known as wireless sensor networks, allow real time monitoring of complex events. Over the last ten years this technology is slowly being applied in many areas such as: agriculture, environmental monitoring and urban planning. However, the technology has yet to see a strong commercial application because of a: lack of universal norms, short lifetime cycle and security concerns. This paper will describe the basic characteristics of a wireless sensor network, followed by a list of different types of security problems that wireless sensor networks face. For each problem, a recommended method for improving security is given, along with all the downsides of such a method. After reviewing the current state of the technology we will propose a new method to improve security and intruder detection for certain types of networks.

The framework is designed to provide a simple and powerful way of Web application component development. Components of the framework can nest, and the framework is designed to be easy to reuse as a component, thus providing its components to be used by the host application. We explain the interfaces required to make this possible - what they provide, what issues they solve, and how their requirement was discovered. We also identify shortcomings of this approach, and issues that will be addressed by future work.

In this paper, we proposed an integral imaging (II) system with a Liquid Crystal (LC) prism array to extend the horizontal viewing angles. The experimental results indicated that the viewing angle is successfully extended by two times without any mechanical movement. We believe that the proposed system is promising for future wide viewing integral imaging systems.

Implementation, usage, and maintenance of complex dynamic web forms can be very time consuming, especially when they have a large number of fields which change very often. In combination with fields that require programming for implementation, the complexity further increases. In this article we describe the problem and suggest the framework for easier implementation of such forms. Later, we describe current implementation, its benefits, and propose future work on this subject.

Derivation of the mathematical model for a robot fish considering forward motion and yaw angle kinematics is presented. This model also includes details of the hydrodynamic force by considering the condition of fish swimming underwater. The nonlinear dynamical model in Carangi form locomotion type is derived by use of Lagrange's equation, which concerning about 4 links of fish robot equivalent model similar to the 4-link planar robot manipulator. Computer simulations conduct both in terms of open-loop response and animation motion of the fish robot swimming. These results indicate feasibility of the model for the robot with swimming speed 0.48 m/s and yaw swing angle ±12 degree. The model derived will be served as a basis for further investigation of control design for the complicated object.

We electrothermally determined the internal electrical resistivity of a single carbon nanocoil (CNC) which was assembled on the AFM tip. A heat-transfer modeling which considered the Joule's heat was employed to extract the electrical resistivity. The current and resistance of the loop circuits were applied in the calculation in which the thermal measurement was not required. During the electrical measurement, the overall resistance of the heating loop depended on the current variation and decreased abruptly at the beginning of the measurement. It was suggested that the contact resistances between the CNC and metal electrodes were eliminated due to the shortened difference of the work functions between the two materials. The developed electrothermal model agreed well with the experiment at steady state and gave the CNC resistivity of 1.64*10 -4 ~8.81*10 -4 Ω-m. This result confirmed the amorphous phase of the synthesized CNC.
