In this project, we worked on a network based cooperative surveillance system. It can be used to track either humans or monitor still objects for anti-theft purpose. We designed multiple ways for user to select the tracking target. The tracking algorithm is based on a Tracking-Learning-Detection pipeline. Experiment results show fast and accurate tracking performance of the system. The potentia...

One of the most risky maneuvers in roads with both directions in the same carriageway and only one lane for each direction is overtaking another vehicle. To overtake becomes particularly dangerous at night, with bad weather conditions and in curves, due to the diminution of the visibility. This paper presents a system to assist the driver in scenarios of bad visibility for overtaking. The syste...

In this paper, we study the transmit diversity of the cooperative relay system employing multiple-input multiple-output (MIMO) technology, especially for the Alamouti space-time block codes (STBC), over slow Rayleigh fading channel. The transmit diversity gain is achieved by STBC and cooperative technology. Maximum ratio combining (MRC) and maximum likelihood detection (MLD) are applied in the ...

This paper studies optimal power allocation to minimize symbol error rate (SER) of amplify-and-forward cooperative diversity networks. First, we analytically solve optimal power allocation problem to minimize SER for three different scenarios, namely, multi-branch single-relay, single-branch multi-relay and multi-branch multi-relay cooperative diversity networks, all subject to a given total re...

This paper investigates the problem of controlling a team of Quadrotors that cooperatively transport a common payload. The main contribution of this study is to propose a cooperative control algorithm based on a decentralized algorithm. This strategy is comprised of two main steps: the first one is calculating the basic control vectors for each Quadrotor using Moore–Penrose theory aiming at coo...

In this paper, a cooperative algorithm to improve the orthogonal space-timefrequency block codes (OSTFBC) in frequency selective channels for 2*1, 2*2, 4*1, 4*2 MIMO-OFDM systems, is presented. The algorithm of three node, a source node, a relay node and a destination node is formed, and is implemented in two stages. During the first stage, the destination and the relay antennas receive the sym...

in this research the cooperative sector's law has been analyzed under the general headings cooperative as an economic sector, cooperative's and cooperatives :union:’s nature, and damages of the acts to the law and the normal function of cooperatives and at the end it has been analytically concluded that regarding the stated structural and legal deficiencies while keeping the cooperati...

the central cooperative banks occupy a crucial position in the pyramidal structure of agricultural cooperative banking system. they from the backbone of the agricultural credit structure and provide the vital line between the primary agricultural societies and the state apex cooperative bank functioning at the state level. the study is based on secondary data obtained from annual reports of edc...
