In this work, novel MoS2/nitrogen-doped carbon shell–core microspheres (MNCS) have been designed and prepared through the microwave-assisted method, and used as counter electrodes for platinum-free dyesensitized solar cells (DSSCs). The results show that as-prepared shell–core composite microspheres possess low charge transfer resistance and high electrocatalytic activity. When used as a counte...

In this chapter, a multi-view people counting system is presented. This system uses as the input data the video sequences acquired by a camcorder. The camcorder can be mounted anywhere (e.g., below a ceiling, on a side wall, or at a corner) with any viewing direction. In order to manage various appearances of people, a multi-view representation of pedestrian is introduced. This representation i...

In this paper we propose a head detection method using range data from a stereo camera. The method is based on a technique that has been introduced in the domain of voxel data. For application in stereo cameras, the technique is extended (1) to be applicable to stereo data, and (2) to be robust with regard to noise and variation in environmental settings. The method consists of foreground selec...

This paper presents and illustrates several cases of risk analysis involving games in two different kinds of situations. The first is a management case in which the principal sets the rules of the game for an agent managing the development of a subsystem and if late may choose to take shortcuts. The second involves a class of adversarial situations, illustrated here by the analysis of counter-i...

OBJECTIVES This report presents trends in cesarean rates for first births and repeat cesarean rates for low-risk women, in relation to the Healthy People 2010 (HP 2010) objectives. Data for the U.S. showing trends by maternal age and race and Hispanic origin are presented. METHODS Cesarean rates were computed based on the information reported on birth certificates. RESULTS With a decrease b...

Effective Communication for marketing is a vital field in business organizations, which is used to convey the details about their products and services to the market segments and subsequently to build long lasting customer relationships. This paper focuses on an emerging component of the integrated marketing communication, ie. social media networking, as it is increasingly becoming the trend. I...

This paper presents a novel approach for automatic people counting in videos captured through a conventional closed-circuit television (CCTV) using computer vision techniques. The proposed approach consists of detecting and tracking moving objects in video scenes to further counting them when they enters into a virtual counting zone defined in the scene. One of the main problems of using conven...

Organizational learning has been playing an important role for competitive advantages for the organization. Managing learning and change in the unique context of small and medium enterprises (SMEs) can obtain benefits from network alliance. The paper seeks to draw attention to learning approaches from adaptive learning to generative learning in a SME in the context of asymmetric learning relati...

A ccording to the Federal Aviation Administration (FAA), 800 million people are expected to board airplanes in 1999. In 1987, the 17 largest airports accounted for more than half of the air passenger enplanement in the United States.’ As airports get larger and more complex, passengers expect more help from curbside to aircraft seat. With extensive hotel, shopping, and recreational complexes sp...
