StreamQuilt: A Timeline-Aware Integration of Heterogeneous Web Streams

This paper proposes a timeline-aware integration system for web streams, such as micro-blogs and real-time information. This system, called StreamQuilt, analyzes implicit and temporal context-dependent relationship among heterogeneous media streams on the web. Our concept is to capture features from a media stream according to its temporal status and relationships to other streams. This system assigns different features to the stream at the different time. This system provides a synchronized streams association mechanism generate a new stream by evaluating the implicit relevance between heterogeneous streams along a timeline. This mechanism utilizes a sequence of data filters to be applied to different filters to streams. Each filter removes contextual ambiguity and various noises from media streams. This approach is advantageous in providing new information by detecting implicit relationships, such as cause-effect relationship and provider-consumer relationship, among web streams. Our system is applicable to mobile advertisement, participatory entertainment systems, and sentiment analysis of social networking services. Keywords-Cross-media infrastructure; heterogeneous stream association; implicit relationship analysis.

A 32 mW 1.25 GS/s 6b 2b/Step SAR ADC in 0.13 µm CMOS

A 1.25 GS/s 6b ADC is implemented in a 0.13 mum digital CMOS process by time-interleaving two SAR ADCs with 2.5 GHz internal clock frequency that converts 6 bits in 3 cycles. 5.5b ENOB at 1.25 GS/s and 5.8b ENOB at 1 GS/s are achieved without any off-line calibration, error correction or post processing. The entire ADC consumes 32 mW at 1.25 GS/s including T/H and reference buffers, and occupies 0.09 mm2 .
Design of Low Voltage D-Flip Flop Using MOS Current Mode Logic (MCML) For High Frequency Applications with EDA Tool

This paper presents a new topology to implement MOS current mod logic (MCML) tri-state buffers. In Mos current mode logic (MCML) current section is improves the performance and maintains low power of the circuit. MCML circuits contains true differential operation by which provides the feature of low noise level generation and static power dissipation. So the amount of current drawn from the power supply does not depends on the switching activity. Due to this MOS current mode logic (MCML) circuits have been useful for developing analog and mixed signal IC’s. The implementing of MCML D-flip flop and Frequency divider done by using MCML D-latches. The proposed MCML D-latch consumes less power as it makes use of low power tri-state buffers. Which promotes power saving due to reduction in the overall current flow in the proposed D flip flop topology is verified though Cadence GPDK-180nM CMOS technology parameters.

Methods and tools for the compilation and software optimization of wireless embedded systems dedicated to applications

Wireless Sensor Networks are are highly constrained in resources: computation, memory and energy. In this context, particular attention must be paid when designing applications, communication protocols and operating systems that will run on the sensor nodes. The purpose of this thesis was to adapt the software models conventionally used for programming applications to the field of sensor networks and to propose methods and tools to build a customized version of the software to run on the sensor nodes from a model of the application. One of the components of a micro-sensor that consumes the most energy is its radio interface. The behavior of a MAC layer protocol can be expressed as a timed automaton with fixed states (which correspond to specific states of the physical device) or free states (the choice for their mapping is left to the programmer). The behavior of a radio device itself can be expressed as an automaton consisting of transitional states (with fixed duration) and non-transitional states (with unlimited duration but with a minimum time duration constraint). The problem of mapping a free state of the software of fixed duration on a path of the physical device by minimizing the energy consumed is proven to be NP-complete. A heuristic to map the free states of an automaton corresponding to a software protocol to states or paths between the states of a physical device is proposed. The approach leads to theoretical gains of 60% for the mapping of B-MAC, a MAC layer protocol. For two categories of operating systems dedicated to Wireless Sensor Networks (event driven and multi-threaded), code skeletons are generated. The simulations under the Worldsens platform of the multi-threaded code skeleton generated for B-MAC and adapted to Mantis OS confirmed the theoretical gains. Experiments on the real platform SensLab have shown that the optimization in terms of energy does not change the functional performance of the protocol.
DESIGN OF A SYNTHESIZABLE PIPELINED MIPS CORE FOR EMBEDDED APPLICATIONS

The use of soft core processors has become inevitable in electronic and mechanical industries for embedded applications. A soft-core processor is a model of hardware description language (HDL) of a specific processor which can be customized for a given application and synthesized for Application Specific Integrated Circuits (ASIC)/FPGA. Usually they contain embedded processors that are often in the form of soft-core processors that execute software code. In this paper soft-core reconfigurable pipelined MIPS processor is developed, which is used in all embedded onchip applications. Specifically, synthesizable VHDL model for un-pipelined and pipelined MIPS Processor is simulated. This design is useful for all synthesized to verify the synthesizability. Modelsim is used for logical verification and synthesizing is carried out using XilinxISE14.2 tool. The results prove the proper functioning of the processor and found to occupy less area compared to previous one.

Evaluation and enhancement of memory efficiency targeting general-purpose computations on scalable data-parallel GPU architectures

This thesis addresses the memory efficiency of general-purpose applications running on massively multi-threaded, data-parallel GPU architectures. Although scalable, data-parallel GPU architectures and their associated general-purpose programming models offer impressive computational capability and attractive power budgets, the pace of migrating general-purpose applications to this emerging class of architectures is significantly hindered by the efficiency of memory subsystem present on these platforms. Programmers are forced to optimize the memory behavior of their code if they are interested in reaping the full benefits of these high performance, data-parallel architectures. In this thesis, we present a comprehensive study of memory access behavior for data-parallel workloads targeting GPUs, and present an algorithmic methodology to address memory inefficiency issues. We establish a mathematical model to capture memory behavior that enables us optimize memory system performance. We present a comprehensive analysis of memory access patterns that fully incorporates the influence of thread mapping and explains the memory behavior of kernels running on GPU hardware—this modeling and analysis serves as a theoretical foundation throughout this thesis. We then show how this new model of memory system activity can be used to enhance the memory efficiency of kernels through a series of algorithmic memory efficiency enhancement techniques. The techniques explored in this thesis include: 1) vectorization via data transformations on vector-based GPU architectures, 2) appropriate memory space selection, and 3) search for an optimized thread mapping and
A Novel Silicon on Diamond Structure to Improve Drain Induced Barrier Lowering

A silicon on diamond structure to improve DIBL is presented. The electrical field penetration through the buried insulator of diamond degrades the DIBL. In the new structure, a second, double insulating material, e.g. SiO 2 is added on top of the buried insulator and partially covers the diamond. The second insulating material has lower electrical permittivity. Therefore the fringing field capacitance is smaller. Simulation results of 22 nm silicon-on-diamond transistor shows 18% improvement in DIBL comparing with conventional SOD structure. Lattice temperature increase of 5% is observed in the new structure compared with the conventional SOD.

and Simple Approximate Analytic Formulas for Calculating the Parameters of Supported Coplanar Waveguides for (M)MIC ' s

Fast, accurate, and simple approximate analytic formulas are presented for calculating the quasi-static-TEM parameters of supported coplanar waveguide structures (SCPW's). These include, the open, covered as well as dielec- tric over-layed SCPW's. These formulas have been designed for use in (M)MIC's-CAD programs and are only valid when- ever the supporting material is of lower permittivity. Compre- hensive comparisons have been made by using a rigorous spec- tral-domain hybrid mode analysis. Accuracy is found to be better than 1 percent for most of the operating range of phys- ical dimensions and available dielectric materials (E, = 1 to 20). Numerical results are also presented in order to investigate the properties of different SCPW structures. (C) (d) Fig. I. Conventional and suggested supported CPW structures. (a) Con- ventional.

Education Compliance and e-Learning in Australia: A Distance Education Model in Exercise and Sport Science

Universities attempt to develop innovative and curr ent degrees in Australia, especially in exercise an d sports science, which is one of the fastest growing disciplines within Australian universities. Compl iance in higher education and relevant to exercise and sport s science degrees is now an expected part of the hi gher education playing field in the Australian universit y sector as Australian and State governments throug h SCOTESE control the developing curricula by enforci ng compliance with national agendas, such at the Australian Qualifications Framework that controls t he expected level of academic achievement and skill levels within the 10 levels of educations from certificate level to doctoral level qualifications. In addition, professional associations also have input and demand compliance in terms of micromanaging the subjects and the curriculum in exercise and sports science, as well as university driven models of compliance in terms of developing and moderating degree programs. The deve lopment of e-learning fully and on-line degrees is now the norm not the exception with some universities d elivering to 70% of their students using this educa tion mode and Open Universities Australia a 100%. However, such dis controlled via compliance and how thi s compliance influences the product universities sell to their customers, the students.
Performance of the CARABAS-II VHF-band synthetic aperture radar

CARABAS-II is an airborne SAR operating in the 20-90 MHz band. The low operating frequency enables detection of concealed objects in dense forests as well as mapping of forest stem volume. A number of calibration experiments have recently been conducted to evaluate system performance. In this paper, we report on some of the results from the analysis. Spatial resolution, measured using 5-m trihedrals, is typically 2.5 m in both slant range and azimuth. The right-left ambiguity ratio, measured using 5-m trihedrals on both sides of the flight track, is about 10 dB for a single antenna element on receive. The noise level varies in the images and includes both multiplicative (integrated sidelobe ratio, right-left ambiguity ratio) and additive (radio-frequency interference, receiver noise) terms. Analysis of images from a recent campaign in northern Sweden shows that the additive noise term is less than -20 dB (noise-equivalent /spl beta//spl deg/) for slant ranges less than 14 km.
Reputation System: Evaluating Reputation among All Good Sellers

A reputation system assists people selecting whom to trust. The “all good reputation” problem is common in e-commerce domain, making it difﬁcult for buyers to choose cred-ible sellers. Observing high growth of on-line data in Hindi language, in this paper, we propose a reputation system in this language. The functions of this system include 1) review mining for different criteria of online transactions 2) calculation of reputation rating and reputation weight for each criteria from user reviews and 3) ranking sellers based on computed reputation score. Extensive simulations conducted on eBay dataset show its effectiveness in solving “all good reputation” problem. So far as our knowledge is concerned, this is the ﬁrst work in Hindi language on reputation system.
A Preliminary Study of Reconstructing Four-Dimensional CT Image Sets by Limited Phase-Specific CT Scans and Image Registration

A 3D block searching image registration algorithm was used to reconstruct 4D CT image sets from limited two or three phase-specific CT scans. A modified first-aid thorax phantom was used to verify the algorithm by acquiring ten known-phase (0o, 20o, 40o, 60o, 80o, 100o, 120o, 140o, 160o and 180o) image sets simulating breath-holding lung with an inflatable balloon. Two methods were used to reconstruct 4D image sets: two-phase approach and threephase approach. The former only used two extreme phases: end-of-exhalation (0o phase) and end-of-inhalation (180o phase). The three-phase approach adds an intermediate phase. The average overlapping ratio for the twophase approach is 95.3% with its range between 93.2% and 97.5%. For the three-phase approach, the average overlapping ratio is 97.3 with its range between 95.6% and 98.4%. Except the extreme top, the maximum 2D contour deviation was 3 mm for the two-phase approach and 1 mm for the three-phase approach respectively. A clinical lung patient case was also used to test the algorithm. There were total three phase-specific CT scans (0o, 90o, and 180o) and the middle phase (90o phase) was used to verify the accuracy of the reconstructed middle phase. The overlapping ratio is 98.5% and the maximum contour deviation is 1.5 mm. With this approach, it is feasible to reconstruct 4D image sets with limited phase-specific, breath-holding CT scan on a single-slice CT scanner in an acceptable accuracy range.

Energy efficiency heterogeneous wireless communication network with QoS support

The overarching goal of this thesis is to investigate network architectures, and find the trade-off between low overall energy use and maintaining the level of quality of service (QoS), or even improve it. The ubiquitous wireless communications environment supports the exploration of different network architectures and techniques, the so-called heterogeneous network. Two kinds of heterogeneous architectures are considered: a combined cellular and femtocell network and a combined cellular, femtocell and Wireless Local Area Network(WLAN) network. This thesis concludes that the investigated heterogeneous networks can significantly reduce the overall power consumption, depending on the uptake of femtocells and WLANs. Also, QoS remains high when the power consumption drops. The main energy saving is from reducing the macrocell base station embodied and operational energy. When QoS is evaluated based on the combined cellular and femtocell architecture, it is suggested that use of resource scheduling for femtocells within the macrocell is crucial since femtocell performance is affected significantly by interference when installed in a co-channel system. Additionally, the femtocell transmission power mode is investigated using either variable power level or a fixed power level. To achieve both energy efficiency and QoS, the choice of system configurations should change according to the density of the femtocell deployment. When combining deployment of femtocells with WLANs, more users are able to experience a higher QoS. Due to increasing of data traffic and smartphone usage in the future, WLANs are more important for offloading data from the macrocell, reducing power consumption and also increasing the bandwidth. The localised heterogeneous network is a promising technique for achieving power efficiency and a high QoS system. Declaration of Originality I hereby declare that the research recorded in this thesis and the thesis itself was composed and organised by myself in the School of Engineering at The University of Edinburgh, except where explicitly stated otherwise in the text.

LAmETx: The New Routing Metric with Load Balancing in WMNs

Wireless Mesh Network (WMN) is a multi-hop mesh network that consists of mesh routers and mesh clients, where mesh routers are static and form the backbone of the mesh network. The static nature of mesh nodes imposes requirements for designing routing metrics that support high throughput and low packet delay. This paper provides a comprehensive survey of various routing metrics that have been proposed for wireless mesh networks and a new routing metrics have been proposed. The literal of this metric is to route the traffic through congestion free areas and balance the load amongst the network nodes. We integrate this new metric in the well known OLSR routing protocol and study the performance of LAmETx through simulations. We show that the proposed metric is able to adapt to changes in load balancing traffic better than existing link metrics such as ETX. We also demonstrate that our metric delivers high-throughput and low delay. Avoidance of congestion at nodes, high throughput, low levels of interference, isotonicity, efficient utilization of channel capacity, minimal transmission delay are some of the desired characteristics of a good routing metric for wireless mesh networks.

A Survey on Modified RTS/CTS Mechanism

The Request-to-Send and Clear-to-Send (RTS/CTS) mechanism is widely used in wireless networks in order to transmit data from source to destination in order to reduce packet collisions (due to Hidden node) and, thus, achieve high throughput. It solves problem over carrier sense multiple access (CSMA), but also arises some additional problems that degrade the performance of RTS/CTS mechanism. These problems are "Exposed Node Problem", "RTS -induced and CTS -induced Problem" and "Masked Node Problem". In this survey paper, we are going to discuss the problems of RTS/CTS mechanism, and give a modification in RTS/CTS mechanism which overcomes the problem of this mechanism and also increases the performance of RTS/CTS mechanism.
