Sensing and aggregation of noisy observations should not be considered as separate issues. The quality of collective estimation involves a difficult tradeoff between sensing quality which increases by increasing the number of sensors, and aggregation quality which typically decreases if the number of sensors is too large. We examine a strategy for optimal aggregation for an ensemble of independ...

BACKGROUND The capacity to demand and use research is critical for governments if they are to develop policies that are informed by evidence. Existing tools designed to assess how government officials use evidence in decision-making have significant limitations for low- and middle-income countries (LMICs); they are rarely tested in LMICs and focus only on individual capacity. This paper introdu...

BACKGROUND There is increasing interest in building the capacity of researchers in low and middle income countries (LMIC) to address their national priority health and health policy problems. However, the number and variety of partnerships and funding arrangements can create management problems for LMIC research institutes. This paper aims to identify problems faced by a health research institu...

The matrix inversion is an interesting topic in algebra mathematics. However, to determine an inverse matrix from a given matrix is required many computation tools and time resource if the size of matrix is huge. In this paper, we have shown an inverse closed form for an interesting matrix which has much applications in communication system. Base on this inverse closed form, the channel capacit...

SETTINGS Partners In Health Rwanda, in collaboration with the Ministry of Health, leads a multipronged approach to develop research capacity among health workers, particularly in rural areas. OBJECTIVES To describe the characteristics of participants and to assess the impact of an introductory research seminar series in three district hospitals in rural Rwanda. DESIGN This was a retrospecti...

The common-mode (CM) signal in wireline transmission systems has proven to provide valuable information exploited for mitigating narrowband noise at the receive side. In this paper, we focus on the case of broadband noise. Treating the CM signal as an additional receive signal, we investigate the capacity of the copper cable channel for different levels of coordination among the users. We intro...

conclusions in this study, some characteristics that had a positive impact on the success of a manager in a hospital surge situation were identified. these characteristics ought to be taken into account when appointing hospital administrators and designing training programs for hospital administrators with the aim of being better prepared to face disasters. background hospital administrators pl...

Capacity can be increased by exploiting the space dimension inherent to any wireless communication system. Recent information theoretic results show that simultaneous use of multiple receive and multiple transmit antennas can offer dramatic increase in capacity. In this paper each cell-site receiver and each user terminal is assumed to be equipped with multiple antennas. Then,under a per transm...

The structure generating function of a language enumerates the number of distinct words contained in the language with respect to their length. Given any unambiguous tuple grammar, a method is described which yields a system of equations, whose unique solution is the structure generating function. The entropy (channel capacity) is an important information theoretic quantity associated with a la...

Tele-operated Load Haul Dump (LHDs) machines are becoming a common tramming solution throughout many mines at INCO Limited in Copper Cliff, Ontario, Canada. To reach maximum productivity from multiple teleoperated LHDs, the system must achive a proper balance of LHD speed in the haulage network and haulage layout geometry. A study was inititated to determine if multiple LHDs, tramming in second...
