The study involves selected indicators of the gross value of industrial output, fixed capital stock, labor input, and energy input. In addition, the panel data fixed effects model is used to measure the capacity utilization of Chinese industries, and analyze the main features of the excess capacity. Finally, according to the research results, this paper puts forward some suggestions to solve the contradictions between overcapacity.

The focus of the paper is to incorporate mobility of the sink node, where it moves across the whole area of the network randomly to enhance the lifetime of Wireless Sensor Networks (WSNs). An algorithm named as “Multi-clustered Energy-Efficient Routing Algorithm with Mobile Sink Node Moving Randomly (MERAM-R)” has been proposed to distribute energy utilization of the sensor nodes by moving the sink node randomly into different locations in the network area. In this approach, the homogeneous and fixed sensor nodes are deployed randomly across the network and a clustering algorithm is applied to divide the sensor nodes (SNs) into different clusters with their own Cluster Heads (CHs). In order to collect data, the sink node moves to different locations across the network randomly without any fixed trajectory. MERAM-R protocol is simulated and its results are compared with the LEACH protocol, the first clustering protocol where the sink node is placed statically at a distance farther from the sensor nodes. It is observed that the lifetime of WSNs using MERAM-R protocol is longer than WSNs using LEACH protocol.

The main ones are related with the vehicle-load dynamics, rundown tracks and unsafe operations. In order to evaluate the railway vehicle dynamics, a multibody system was implemented to model a railway boxcar with 24 DOFs. Based on the system’s excitation, the vehicle behavior can be evaluated in several operating conditions, and the dynamic system is solved with the Runge-Kutta method for numerical integration. When comparing results from a known model to the ones from the developed program, Dynamic Analysis of Railroad Cars (DARC), a consistent correlation is found. When passing over a jog type aperiodic irregularity, the boxcar of 100 t suffers a vertical acceleration of the car body equivalent to 0.38g and thus lowers load on the wheels for an instant. Hence, it is possible to conclude that this irregularity is severe. Considering that AAR establishes a minimum value of 10% of load over the wheel for traffic conditions, the obtained results show there would not be derailment, as the minimum load obtained on the wheel is of 44% in relation to the static load value.

If the private key of a signer is exposed then security of the system is totally lost. Key-insulation mechanism minimizes the damage caused by the exposure of private keys in cryptographic schemes. To deal with the key-exposure problem in ID-based schemes, private keys have to be updated at very short intervals; but it will increase the risk of helper key exposure. In order to improve the security and efficiency of key insulation mechanism in ID-based signatures, in this paper, we proposed an ID-based parallel key insulated signature scheme. This scheme uses the bilinear pairings over elliptic curves and is provably secure in the ROM model with the assumption that the CDH problem is intractable. This scheme is strong key- insulated and allows frequent key updates without increasing the risk of helper key exposure and hence improve the security of the system. Also our IDPKIS Scheme reduces the computational, communicational complexity and hence the scheme can be deployed on inexpensive, lightweight and mobile devices. Page(s): 24-28 2018-01-01T00:00:00Z
