Micro Air Vehicles (MAVs) equipped with various sensors are able to carry out autonomous flights. However, the self-localization of autonomous agents is mostly dependent on Global Navigation Satellite Systems (GNSS). In order to provide an accurate navigation solution in absence of GNSS signals, this article presents a hybrid sensor. The hybrid sensor is a deep integration of a monocular camera...
The distributed coordination function (DCF) of IEEE 802.11 MAC protocol is not scalable as the number of users on a network increases. We propose two new contention resolution schemes to reduce the number of collisions between a large number of contending mobile stations. The hybrid DCF (H-DCF) scheme splits contention resolution into two phases to improve scalability. Enhanced hybrid DCF (EHDC...
this research set out to evaluate the effect of combined biological and chemical nitrogen fertilizers on some corn hybrids. to this end an experiment was conducted as split plot on the basis of randomized complete block design with four replications. main plots were included: use of chemical and biological fertilizers in four levels: 100% chemical fertilizer, 75% chemical fertilizer + 100% bio-...
Recent terrorist attacks on the United States have exposed the need for better surveillance and situational awareness technologies. Organizations created to address these needs are aggressively funding research in the use of Micro Air Vehicles for homeland security missions. Such missions have been occurring in caves, tunnels, and urban areas. By mimicking flying insects which navigate in these...
integration reinforcement of renewable energy resources and phevs through hybrid ac-dc local network
the share of dc-based renewable energy resources (rers) and electricity storage systems are increasing due to developments of smart grid technologies. moreover, the share of dc-based load has rapid growth due to significant developments of power electronic technologies. therefore, a more flexible power system is required for efficient integration of emerging loads and generators. in this paper,...
At least eight leukocyte interferon genes (IFL) and the single fibroblast interferon gene (IFF) have been located on chromosome 9 in humans. In somatic cell hybrids of human and mouse cells containing a normal complement of mouse parental cell chromosomes but reduced numbers of human chromosomes, the human leukocyte and fibroblast interferon DNA sequences were present only when human chromosome...
Eighty patients who had undergone routine meniscectomy were divided into two groups for postoperative management. The first 40 patients were treated by the traditional method of a compression bandage with a backsplint, followed by a 10-day stay in hospital. In the other 40 patients a compression bandage was applied, reinforced by a plaster cylinder. Weight-bearing was allowed with the aid of cr...
Surface-localized rat RT1 alloantigens on isolated hepatocytes have been used to achieve partial purification of putative premalignant liver cells from rats undergoing chemically induced hepatocarcinogenesis. Genotypic mosaic rat livers were con structed by transplantation of carcinogen-altered F-344 (n77'"1) or WF (RT1U)donor liver cells into livers of WF x F-344 F, host rats, whose liver cell...
C lathrin is best known for its role in endocytosis and other membrane traffi cking events, but the protein's heavy chain has several additional functions , including organization of mitotic spindles and coordination of actin fi laments at intercellular adhesions. Vassilopoulos et al. now reveal that the clathrin heavy chain (CHC) also helps to organize skeletal muscle sarcomeres by promoting t...
