This paper is concerned with the issues of observer-based consensus control for a class of networked multi-agent systems with time-varying delays and random packet-dropouts. The distributed multi-agent system whose consensus control protocol is accomplished through a communication network, via which each agent can be remotely controlled, is referred to as networked multi-agent systems (NMAS). F...

OBJECTIVE Attrition is a common problem in weight management. Understanding the risk factors for attrition should enhance professionals' ability to increase completion rates and improve health outcomes for more individuals. A model that draws upon neuropsychological knowledge on reward-sensitivity in obesity and overeating to predict attrition is proposed. METHODS A total of 52 participants i...

Is the New Immigration Really So Bad? This paper reviews the recent evidence on U.S. immigration, focusing on two key questions: (1) Does immigration reduce the labor market opportunities of less-skilled natives? (2) Have immigrants who arrived after the 1965 Immigration Reform Act successfully assimilated? Looking across major cities, differential immigrant inflows are strongly correlated with...

The Great Observatory Origins Deep Survey (GOODS) Spitzer Legacy Program has obtained ∼ 23.2 hours of IRAC observations in the HDFN and the CDF-S (∼ 330 arcmin in total), among which a sub-area of ∼ 50 arcmin in the HDF-N has been observed to a depth of ∼ 72 hours. Utilizing these deep IRAC data, we study the stellar masses and star formation histories of galaxies at z ≈ 6. While some of the i-...

This paper introduces a packet-based dual-rate control strategy to face time-varying network-induced delays, packet dropouts and packet disorder in a Networked Control System. Slow-rate sensing enables to achieve energy saving and to avoid packet disorder. Fast-rate actuation makes reaching the desired control performance possible. The dual-rate PID controller is split into two parts: a slow-ra...

Family is the most influential agent among the different social factors that significantly influences the growth and development of any child. The family environment, economic status, socio-educational status of parents influences the different milestones of child development. Education is an important dimension of child’s development and it’s an important driving force in the process of social...

In this paper we describe how human target following performance changes in the presence of latency, latency variations, and signal dropouts. Many modern games and game systems allow for networked, remote participation. In such networks latency, variations and dropouts are commonly encountered factors. Our user study reveals that all of the investigated factors decrease tracking performance. Th...

It is well known that approaching death accelerates cognitive decline. The converse issue, that is, the question of whether rapid declines in cognitive ability are risk factors for imminent death, has not been investigated. Every 4 years between 1983 and 2003, we gave 1,414 healthy community residents who were aged between 49 and 93 years the Heim AH4-1 test of fluid intelligence. A modified An...

This paper examines whether conclusions about the relationship between education and labor market risk depend on the use of commonly applied procedures to clean data of extreme values. The analysis uses fifteen years of data from the Panel Study of Income Dynamics to demonstrate that conclusions about the relationship between education and labor market risk are sensitive to how extreme values o...

In this paper, the nonlinear systems with time delay network control is discussed transmission delays and packet dropouts for networked control system with random time delay are analyzed. In this paper, online delay estimation method to obtain the delay value, the delay value is an input parameter of fuzzy adaptive PID controller, fuzzy PID temporal adjustment based on genetic algorithm and Par...
