Abstract:
Transcription factor binding sites are essential components of the machinery that controls gene expression. In the absence of experimental data, computational approaches are used to predict binding sites based on promoter DNA sequence. However transcription factor binding depends not just on sequence but also the packaging of the DNA molecule. Nucleosomes, as the smallest unit of DNA packaging, affect transcription factor binding by obstructing protein-DNA interactions.<br>We use an empirically-derived relationship between binding sites and nucleosome positioning to augment an existing computa

Abstract:
Abstract In the last few years, location-awareness has emerged as a key technology for the future development of mobile, ad hoc and sensor networks. Thanks to location information, several network optimization strategies as well as services can be developed. However, the problem of determining accurate location, i.e. positioning, is still a challenge and robust algorithms are yet to be developed. In this thesis, we focus on the development of distance-based non-cooperative and cooperative algorithms, which is derived based on a non-parametric non- Bayesian framework, specifically with a Weight

Abstract:
Surveillance is an important application for unmanned aerial vehicles (UAVs). The sensed information often has high priority and it must be made available to human operators as quickly as possible. Due to obstacles and limited communication range, it is not always possible to transmit the information directly to the base station. In this case, other UAVs can form a relay chain between the surveillance UAV and the base station. Determining suitable positions for such UAVs is a complex optimization problem in and of itself, and is made even more difficult by communication and surveillance constrai

Indoor positioning has become an important research field in recent years. This is due to the potential services or products that can be offered, which would be very useful for users in several applications, and the interesting commercialization possibilities. But nowadays the most developed positioning systems are used outdoors, and for example GNSSs do not provide indoor coverage, so the efforts are focused on other local radio technologies. In particular, ultra-wideband is the object of this thesis. In this thesis a set of cooperative algorithms are presented and intended for use in the loc

Precision of measuring distance between mobile and base transceiver station is a key element of positioning base transceiver station. More precision for measuring distance, more precision for positioning base transceiver station. The error of measuring distance is 555 meters base on timing advance(TA) technique. It is very difficult to get the reasonable and acceptable results in GSM 2G network. 　　This paper is inspired by the “divide and conquer” algorithm. Prior to the introduction of GPS enable

Abstract:
In this thesis, we consider the problem of finding the geographic position of a transmitter device (e.g. mobile phone), denoted as user equipment (UE), based on signal parameter estimates such as angle-of-arrival or time-of-arrival that are provided by surrounded sensors or base stations. If line-of-sight (LOS) channels between the UE and the base stations exists, high positioning accuracy can be obtained using trilateration or triangulation techniques. However, this assumption is ideal and not often encountered in practice. Especially in urban areas and hilly terrain, reflections at obstacles

Abstract:
This research work presents of study of ultra-wide band (UWB) indoor positioning considering different type of obstacles that can affect the localization accuracy. In the actual warehouse, a variety of obstacles including metal, board, worker and other obstacles will have NLOS (non-line-of-sight) impact on the positioning of the logistics package, which influence the measurement of the distance between the logistics package and the anchor , thereby affecting positioning accuracy. A new developed method attempts to improve the accuracy of UWB indoor positioning, through and improved posi

Abstract:
博士<br>臺灣大學<br>資訊管理學研究所<br>95<br>From either practical or theoretical viewpoint, wireless sensor network (WSN) techniques are new and important research issues. Numbers of interesting applications for WSNs have been investigated, e.g., surveillance, target positioning, tracing, and health care. Sensor networks have been forecasted to apply variously, both the civilian and military domains. There are two important issues usually are concerned on WSNs design. One is to construct a qualified WSN for applications to guarantee desired quality of service (QoS). The other challenge is to prolong the n
