We have witnessed the emergence of a new set of corporations that have been able to grow faster than the competition with fewer resources. Corporations such as Uber and Air Bnb have grown to become one of the largest of their kind in less than ten years: Uber was established in 2009 and is currently the world's biggest taxi company. Interestingly, it does not own any vehicles. Similarly, Air Bnb was established in 2008 and is currently is the world's largest accommodation provider. Again, interestingly, it does not own any real estate. What is happening here, and more importantly, what kind of business model innovation has taken place, if any? This paper aims to shed light on these questions by analyzing the business models of these companies and contrasting them with those of their respective industry incumbents. The results highlight the importance of software in automatizing and outsourcing otherwise capital and labor intensive activities as well as enabling the business model to build upon logical resources composed of decentralized, transient slack resources of individuals and companies.

This paper proposes an iterative evolutionary algorithm with emulating nodes' local movement for searching the best localization accuracy in range-free scenario. All localization methods face a trade-off between the solution quality and computation cost. When sensor network localization in range-free scenario is considered as a constraint satisfaction problem, localization will reach the highest accuracy but with huge computation complexity. To solve the constraint satisfaction, some characteristics that only exist in range-free localization problem are utilized as heuristics in the search of nodes' positions. They are summarized as simple and complex movement to emulate nodes' local movement, and proved to be effective to find a suitable searching direction and jump out of local-minimums existing in the localization. Those emulations are then included in each iteration of a two-objective evolutionary algorithm minimizing the number of node-pairs with violated connectivity, as well as the value quantitating how worse of the violations. Simulation results show that the proposed algorithm can greatly decrease the reach high-accurate positions within limited iterations.

This paper design controller for the uncertain neutral delay system. The uncertain neutral delay system includes norm bounded uncertain system parameters and unknown constant delay. The paper uses uncertain neutral systems with structural features, and constructs appropriate Lyapunov function to obtain feedback control law. Compared with the previous methods for solving the Riccati equation, this method overcomes the shortcoming of Riccati equation emphasizing the center solution. Simulation results show that, the conservatism of the controller designed in this paper is reduced, and the controller easy to operate and application.

In this work, a variational Bayesian robust linear dynamic system (VBRLDS) approach is proposed for dynamic process modeling and monitoring. Traditional linear dynamic system (LDS) constructed with Kalman filter is designed by Gaussian assumption which can be easily violated in outlier contaminated modeling situations. To deal with this issue, the conventional Gaussian-based Kalman filter is modified with heavy tailed Student's t-distribution so as to deal with modeling outliers. Then, a variational Bayesian expectation maximization (VBEM) algorithm is developed for learning parameters of the robust linear dynamic system. For process monitoring, traditional residual space modeling method of SPE statistics are modified. To explore the feasibility and effectiveness, our proposed method is applied into fault detection and is comparatively studied with several other methods on the Tennessee Eastman benchmark. © 2015, IFAC (International Federation of Automatic control) Hosting by Elsevier Ltd.

Hazard and operability(HAZOP) methodology is an important Process Hazard Analysis(PHA) technique for ensuring safety production in chemical industry. Due to the lacks of accuracy and reliability in manual HAZOP analysis, the quantitative HAZOP analysis has gained more and more attention. In this work, a process simulation-based HAZOP analysis method and its flow chart are proposed. And the proposed method is applied to a steam generation subsystem in an ethylene pyrolysis unit on a dynamic process simulation platform. All deviation parameters of system can be calculated and described quantitatively. The case study shows the proposed method is useful for the effective risk prevention and control measures in a chemical process.

The optimization of the energy consumption is one of the most important problems that face the designers of mobile robots. This implies that it is significant to analyze the energy consumption of hydraulic quadruped robot under different gait parameters. In this paper, the kinematics and dynamics models of a hydraulic quadruped robot are established firstly. Then, the length of step, the height of step, the height of center of mass, and the duty ratio of gait cycle are set as the primary research points about the energy consumption of mobile robot. In addition, the energy consumptions of the feet with and without mechanical springs are compared and analyzed. In order to get the visual observation of energy cost in the hydraulic quadruped robot during a waking cycle and the best set of locomotion variables that achieve the energy optimization, related simulations are done for gait parameters. Finally, the results provide a recommendation for the gait planning of the hydraulic quadruped robot, that is, the quadruped robot should walk with a relatively long step length, a relatively low height of step, a relatively high height of center of mass, and a relatively small duty ratio of gait cycle.

At present, the studies on multi-team antagonistic games (MTAGs) are still in the early stage, because this complicated problem involves not only incompleteness of information and conflict of interests, but also selection of antagonistic targets. Therefore, based on the previous researches, a new framework is proposed in this paper, which is dynamic multi-team antagonistic games with incomplete information (DMTAGII) model. For this model, the corresponding concept of perfect Bayesian Nash equilibrium (PBNE) is established and the existence of PBNE is also proved. Besides, an interactive iteration algorithm is introduced according to the idea of the best response for solving the equilibrium. Then, the scenario of multiple unmanned aerial vehicles (UAVs) against multiple military targets is studied to solve the problems of tactical decision making based on the DMTAGII model. In the process of modeling, the specific expressions of strategy, status and payoff functions of the games are considered, and the strategy is coded to match the structure of genetic algorithm so that the PBNE can be solved by combining the genetic algorithm and the interactive iteration algorithm. Finally, through the simulation the feasibility and effectiveness of the DMTAGII model are verified. Meanwhile, the calculated equilibrium strategies are also found to be realistic, which can provide certain references for improving the autonomous ability of UAV systems. © 2014 Chinese Association of Automation.

Encryption algorithms are applied to a variety of fields and the security of encryption algorithms depends heavily on the computational infeasibility of exhaustive key-space search. RC4 algorithm has an extensive application for stream encryption, however, the disadvantages of traditional RC4 serial algorithm are large computational quantity and slow computation speed, which means a great challenge for throughput of computing system. Graphics processors recently have been widely used as accelerators for high throughput computing. In this paper, GPU is used to improve the efficiency and performance of attacking RC4 algorithm. First, we revised RC4 algorithm to make it easier to parallelize on a GPU. Then we take advantage of constant memory and shared memory in GPU to search the key space of RC4 algorithm efficiently. Besides, we solved the bank conflict problem in shared memory to further improve the performance. Our approach was evaluated in the whole key space of 40-bit, and the results show it can complete searching of the whole key space within 12.8 hours. © 2016 IEEE.

n-Alkanes (n > 4) show very similar physical characteristics and it is quite difficult to identify them by direct observation. Here, a direct identification method based on ambient mass spectrometry was developed to distinguish n-alkanes (n ≥ 4). Three gaseous alkanes (propane, n-butane and iso-butane) and five liquid alkanes (n-pentane, n-hexane, n-nonane, n-dodecane, and n-tridecane) had been analyzed with two sampling ways: 1) the central tube sampling and, 2) the atmospheric pressure-volatilizing sampling. The sample was ionized through plasma, which was generated from a Microwave Plasma Torch (MPT). The results show that after the central tube sampling, the alkanes are more easily to dissociate by losing—CH2–, then the generated fragment ions will recombine to prolong the carbon chain lengths. The end products are the new alkanes by losing or adding n (–CH2–) (n is not fixed) from the original alkanes. While after the atmospheric pressure-volatizing sampling, n-alkanes (n ≥ 4) are more easily to produce ions of [M+13]+ regularly. Thus, based on this phenomenon, n-alkanes (n ≥ 4) can be identified directly. Also, the developed method shows very good detection limit, which can be as low as 0.7 nmol/mol. © 2015 Taylor & Francis Group, London.

In this paper, we present a novel learning framework for traversable region detection. Firstly, we construct features from the super-pixel level which can reduce the computational cost compared to pixel level. Multi-scale super-pixels are extracted to give consideration to both outline and detail information. Then we classify the multiple-scale super-pixels and merge the labels in pixel level. Meanwhile, we use weighted ELM as our classifier which can deal with the imbalanced class distribution since we only assume that a small region in front of robot is traversable at the beginning of learning. Finally, we employ the online learning process so that our framework can be adaptive to varied scenes. Experimental results on three different style of image sequences, i.e. shadow road, rain sequence and variational sequence, demonstrate the adaptability, stability and parameter insensitivity of our method to the varied scenes and complex illumination.
