We consider a multimarket framework where a set of firms compete on two interrelated oligopolistic markets. Prior to competing in these markets, firms can spy on others in order to increase the quality of their product. We characterize the equilibrium espionage networks and networks that maximize social welfare under the most interesting scenario of diseconomies of scope. We find that in some s...

— This paper investigates intermediate input effects and labor pooling in the context of urban informality, examining the handicraft industry of Nairobi, Kenya. The paper tests if conditions found in informality interfere with transition pathways in production clusters. 102 semi-structured interviews were conducted with industry participants, including 69 production firms. Findings confirm the ...

This paper presents a method for functional projective H∞ synchronization problem of chaotic systems with external disturbance. Based on Lyapunov theory and linear matrix inequality (LMI) formulation, the novel feedback controller is established to not only guarantee stable synchronization of both drive and response systems but also reduce the effect of external disturbance to an H∞ norm constr...

This paper describes a robust approach exploiting input-output decoupling controller for mobile manipulators. The robust controller consists of using a classical proportional-derivative (PD) feedback structure to stabilize the position error plus an additional disturbance observer (DOB) to compensate external disturbances and uncertainties. Simulation results on a mobile platform with 2-DOF man...

In this paper, we present various procedures to support a ZUPT-based MEMS IMU navigation application by available external building models and photographs of evacuation plans. In detail, these are approaches for horizontal alignment of the track using the external building shell, for height correction by stair and elevator detection, for the extraction of the initial position and direction usin...

Keywords are valuable means for characterizing texts. In order to extract keywords we propose an efficient and robust, language-and domain-independent approach which is based on small word parts (quadgrams). The basic algorithm can be improved by reexamining and re-ranking keywords using edit distance (i.e. Levenshtein distance) and an algorithm based on the relativistic addition of velocities ...

We report five cases of duplicated external ear canal with especial attention to its histology and surgical care of facial nerve for their complete resection. These five patients were selected from 50 cases of first bronchial cleft anomalies including atretic external ear canals, preauricular fistula, cyst and sinuses. The characteristic histopathology and clinical features such as external ope...
