A Solution to Privacy Preservation in Publishing Human Trajectories

With rapid development of ubiquitous computing and location-based services (LBSs), human trajectory data and associated activities are increasingly easily recorded. Inappropriately publishing trajectory data may leak users’ privacy. Therefore, we study publishing trajectory data while preserving privacy, denoted privacy-preserving activity trajectories publishing (PPATP). We propose S-PPATP to solve this problem. S-PPATP comprises three steps: modeling, algorithm design and algorithm adjustment. During modeling, two user models describe users’ behaviors: one based on a Markov chain and the other based on the hidden Markov model. We assume a potential adversary who intends to infer users’ privacy, defined as a set of sensitive information. An adversary model is then proposed to define the adversary’s background knowledge and inference method. Additionally, privacy requirements and a data quality metric are defined for assessment. During algorithm design, we propose two publishing algorithms corresponding to the user models and prove that both algorithms satisfy the privacy requirement. Then, we perform a comparative analysis on utility, efficiency and speedup techniques. Finally, we evaluate our algorithms through experiments on several datasets. The experiment results verify that our proposed algorithms preserve users’ privay. We also test utility and discuss the privacy-utility tradeoff that real-world data publishers may face.
A Study on the Battle Management Language Application for the C4I and M&S Interoperation in ROK Forces

Battle Management Language (BML) is defined as an unambiguous language intended to provide for command and control of simulated and live forces in U.S. It has been developed to connect between command and control system and Modeling & Simulation in the U.S., including NATO M&S Working Group. Its goal is to provide situational awareness and offer a path forward for interoperation of C2 systems and simulations. This study deals with BML development in U.S. that begins from army and is being expanded in multinational environment. It also proposes the BML application for C4I and M&S interoperation in the Korean forces. Recent developments of BML in U.S. have shown the potential for interoperation between C2 systems and simulations in a coalition environment. Finally, this study proposes a general BML application method and shows the example of its application to the Korea Joint Command Control System (KJCCS). It provides an architecture and a milestone for BML application in the Korean forces.
A System Dynamics Approach to Modeling Gas Turbine Combustor Wear

This paper deals with the development of the basic understanding of dynamic and wear problems of combustor systems. A system dynamic modeling approach has been developed using a general purpose dynamic/wear analysis program (Mechanism Analysis Program, MAP), and excellent validation has been achieved via laboratory tests. The objective is to develop a generic design/analysis tool, both, for quick evaluation of preliminary designs, and for detailed design studies to create improved/optimized combustor designs from a wear/life perspective.Dynamic simulations of two different designs are run: Many worn field samples are available for one design, and laboratory test results for the other. The wear patterns on the former are matched very well by the analytical model. Excellent correlation, too, is obtained with the dynamic (accelerometer) measurements on the latter. It is, now, possible to isolate system dynamic causes (such as resonance) from material related ones (such as hardness) when designing for long life. © 1992 ASME
Consolidated Deep Actor Critic Networks

The works [Volodymyr et al. Playing atari with deep reinforcement learning. arXiv preprint arXiv:1312.5602, 2013. ] and [Volodymyr et al. Human-level control through deep reinforcement learning. Nature, 518(7540):529–533, 2015. ] have demonstrated the power of combining deep neural networks with Watkins Q learning. They introduce deep Q networks (DQN) that learn to associate High dimensional inputs with Q values in order to produce discrete actions, allowing the system to learn complex strategies and play Atari games such as Breakout and Space invaders. Although powerful the system is limited to discrete actions. If we wish to control more complex systems like robots we need the ability to output multidimensional continuous actions. In this paper we investigate how to combine deep neural networks with actor critic models which have the ability to output multidimensional continuous actions. We name this class of systems deep actor critic networks (DACN) following the DQN naming convention. We derive and experiment with four methods to update the actor. We then consolidate the actor and critic networks into one unified network which we name consolidated deep actor critic networks (C-DACN). We hypothesize that consolidating the actor and critic networks might lead to faster convergence. We test the system in two environments named Acrobot (under actuated double pendulum) and Bounce (continuous action Atari Breakout look alike).
Discrete Fourier transform spreading-based generalised frequency division multiplexing

Generalised frequency division multiplexing (GFDM) has gained significant importance as a contender for the fifth generation (5G) air interface. The peak-to-average power ratio (PAPR) of GFDM is high due to the use of a same pulse shaping filter per subcarrier and the addition of different subcarriers at the transmitter. Proposed is the use of discrete Fourier transform (DFT) spreading-based GFDM transmission to reduce the PAPR. It is found that DFT spreading helps to reduce the PAPR of GFDM significantly. It is also seen that the bit error rate performance, which is computed through simulation and using an analytical expression of the signal-to-interference-plus noise ratio, is not compromised by DFT spreading but rather is improved in the frequency selective fading channel.

A novel circular grooved and ridged waveguide phase shifter with dielectric‐loading is proposed, fabricated, and discussed in this article. Both experimental and numerical results obtained show that the proposed circular grooved and ridged waveguide phase shifter, when compared with the conventional one, has larger differential phase shift, smaller length, and no obviously changed insertion loss. © 2007 Wiley Periodicals, Inc.

Analysis of the Behavior of Fluorescent Whitening Agents in Recycling Process of White Ledger

ABSTRACT White ledger usually includes white office paper, computer paper, and copy machine paper. Because these grades need high optical properties, fluorescent whitening agents (FWAs) are widely used in the papermaking process. FWAs are the most powerful and effective chemical used to obtain high CIE whiteness and ISO brightness in papers. The rising demand for white or ultra-white papers has increased the use of FWAs. However, FWAs used in white ledger can restrict its use, even though white ledger is widely used as a raw material in paperboard mills. Therefore, it is necessary to develop methods to control FWAs from white ledger to increase its use in paperboard mills. In this study, the behaviors of disulpho fluorescent whitening agent (D-FWA), tetrasulpo fluorescent whitening agent (T-FWA), and hexasulpho fluorescent whitening agent (H-FWA) during the recycling process were identified as a first step to remove FWAs from white ledger. We prepared four types of pa-pers (dyed with D-FWA, T-FWA, and H-FWA), disintegrated these papers, and made handsheets. This recycling process was carried out three times in a laboratory. After each round of recycling, the hand-sheets' CIE whiteness and fluorescence index were measured, and the distribution of FWAs in the Z-di-
A two-stage finite element model of a meander coil electromagnetic acoustic transducer transmitter

This paper presents a two-stage numerical model of a meander coil electromagnetic acoustic transducer transmitter operating on the Lorentz force principle. This model was used to predict the ultrasonic A-scan signals for bulk (longitudinal and shear) and guided (Rayleigh) waves in isotropic homogeneous materials. The simulation results agree with the experimental results. The grating effects of the meandering coil, for different coil spacings, are also discussed in this paper.
Evaluating New Urbanist Plans in Post-Katrina Mississippi

Immediately following Hurricane Katrina, the Mississippi Governor's Commission for Recovery, Rebuilding and Renewal partnered with the Congress for the New Urbanism to provide teams of planners and designers to work with communities along the coast in preparing rebuilding plans. Following a week-long charrette in October 2005, each coastal community was provided with a rebuilding plan that was intended to be based on the principles of New Urbanism. The initial plans have been followed up with further long-range planning. Two years after Katrina, this paper examines the degree to which New Urbanism has been incorporated into the long-range comprehensive, master and other rebuilding plans developed in the communities along the coast in Harrison County, Mississippi. This study finds that New Urbanist principles were integrated into some community plans, but were largely absent from others. In those that do incorporate the principles, the realities of post-Katrina planning created serious challenges to the feasibility of implementing New Urbanist plans. While the goals of the New Urbanist consultants were to create better communities and regions, these good intentions have primarily failed on the Mississippi Gulf Coast. In many cases, communities felt dissatisfied with their design-based plans because they were not appropriate for the time and place of post-Katrina Mississippi. The paper concludes by offering suggestions on how communities can improve their plans relative to integrating the principles of New Urbanism that can help rebuild better communities, while balancing community priorities for rebuilding.
JOURNAL OF PLANNING AND LAND MANAGEMENT AN ANALYSIS OF ORGANISATIONAL AND TASK STRESSORS AMONG CONSTRUCTION PROFESSIONALS IN GHANA

The construction industry constitutes one of the imperative and promising industries in Ghana in term of output and outcome. However, the stressful nature of this industry has become an issue of concern to many. The study identifies and examines the critical organisational and task stressors among construction professionals in Ghana, using sequential explanatory mixed approach by means of mainly questionnaire survey and interviews. Data from a sample size of 372 construction professionals within the ten regions of Ghana were examined using factor analysis and pairwise ranking. The results of this study reveal that organizational policies, treatment and reward constitute the most critical organizational stressors. Overload and job description ambiguity turned out as the most critical task stressors. It was uncovered that organisation stressors are ubiquitous. The findings of this study can serve as policy alert for an optimal stress and employee-oriented policies as well as training scheme for construction professionals in Ghana. In-depth nationwide qualitative study on organisational and task stress coping strategies of construction professionals is recommended.
Microstrip/slotline transitions: modeling and experimental investigation

An analysis of microstrip/slotline transitions is given using a network description through transmission-line models. Different transitions, such as transitions containing uniform and nonuniform lines as well as soldered and virtually shorted microstrip lines, are treated. Although a transition with a soldered microstrip short offers the largest bandwidth, optimal combinations of different microstrip and slot stub diameters can be found by modeling. In the case of a virtual short through an optimally chosen circular microstrip stub, the bandwidth is typically about 10% below the maximum achievable value of a soldered short. The validity of the modeling results is verified experimentally by measuring the transmission coefficient of a cascade of two transitions separated by a slotline in the frequency range from 1 to 16 GHz. For practical applications, design curves are given for 0.635-mm-thick alumina substrates. >
Mixed Methods Use in Project Management Research

Mixed methods research is increasingly being used in business and management disciplines, in spite of positivist traditions. The aim of the study is twofold: (1) to examine the types of mixed methods approaches being used, and (2) to determine the quality of the reporting of mixed methods studies published in the field of project management. A retrospective content analysis of articles from three ranked project management journals was undertaken for a sample period of 2004 to 2010. Our findings suggest the field of project management is in need of capacity building in relation to the good reporting of mixed methods studies.
The electromagnetic effect of cooling fins

The electromagnetic effect of cooling fins is studied by solving Maxwell equations numerically using a FDTD method under high‐frequency operating conditions. The fin is attached to a square IC chip to form a package. The overall size of the package is 25 mm × 25 mm × 17.5 mm. A smooth compact pulse with a reference frequency of either 1 or 2.5 GHz is used as the excitation source of EM waves. Six fin configurations are investigated. Computational results indicate that a fin can act as an antenna. For the present type of excitation source, resonance could occur roughly at frequencies of 2.5, 5 and 7.5 GHz, depending on the source reference frequency and fin geometries. Thus, fin effects should be considered in the electrical design phase since noises could be induced in the circuit due to the presence of fins. Copyright © 2006 John Wiley & Sons, Ltd.
A New Method Based on HMMs and K-Means Algorithms for Noise-Robust Voice Activity Detector

In this paper, we proposed left-right hidden Markov models (HMMs) combination with k-means threshold of Likelihood ratio test (LRT) to identify the start and end of the speech. This method builds two models of non-speech and speech but not two states, i.e. each model could conclude several states. In the experiments we present the Voice Activity Detection (VAD) results between two states hidden semi-Markov model (HSMM) and proposed algorithm. We also compare accuracy and robust between the k-means threshold and the adaptive threshold in high signal to noise rate in the background noise. It presents that k-means threshold is more effective than the adaptive threshold and the proposed method also make a better performance than two states HSMM based VAD, especially in the low signal-to-noise ratio (SNR) environment.
Biomechanical and modelling analysis of shaft length effects on golf driving performance

The purpose of this thesis was to determine how shaft length affects golf driving performance. Shaft length effects on the golf swing have been of interest to several researchers (including Egret et al., 2003; Reyes and Mittendorf, 1999 and Mitzoguchi and Hashiba, 2002). A range of drivers with lengths between 46" and 52", representing lengths close to the 48" limit imposed by the R&A Rules Limited (2004), were assembled and evaluated. A 5-camera three dimensional motion analysis system tracked skin markers attached to 9 low-medium handicapped (5.4 ± 2.8) golfers. Clubhead and ball launch conditions and drive distance and accuracy were determined for 5 lowmedium handicapped golfers (5.1 ± 2.0) and 7 elite golfers (0.21 ± 2.41) who performed shots on a purpose-built practice hole. Finally, motion analysis was conducted for an elite golfer (+1 handicap) and experimentally obtained marker data was used to drive a large-scale musculoskeletal model. Low-medium handicapped golfers demonstrated more significant variation in performance due to shaft length than elite golfers. Postural kinematics remained largely unaffected, as were ball spin, launch angle and swing tempo. As shaft length increased from 46" to 52", initial ball velocity (+ 1.90 ms, p < 0.05) and ball carry (+ 14 yds, p < 0.001) increased significantly for low-medium handicapped golfers. As shaft length increased from 46" to 50" initial ball velocity (+ 1.79 ms, p < 0.01) increased significantly for elite golfers. Ball carry (+ 4.73 yds, p = 0.152) also showed NS increases for elite golfers. Furthermore, as shaft length increased, for all club comparisons there were NS decreases (p = 0.063) in shot accuracy for low-medium handicapped golfers, but no decrease in accuracy for elite golfers. Model simulated results, including posture, timing and predicted muscle force compared well with experimental results (r > 0.98, p < 0.05). Simulations showed that for the range of clubs modelled (46" to 50") hip/shoulder differential angle at the top of the backswing increased significantly (+ 6.13o, p < 0.001) as shaft length increased, and each 2" increase in shaft length required a NS additional 4.5 N force (p = 0.117) to maintain normal swing kinematics. The results from this thesis indicate that modest improvements in shot performance brought about by increasing driver length are the result of increased hip/shoulder differential angle at the top of the backswing and increased predicted muscle force. viii Nomenclature ADD Address CFD Computational fluid dynamics CNS Central nervous system COG Centre of gravity COM Centre of mass COR Coefficient of restitution DOF Degree of freedom GRF Ground reaction force IMP Impact MOCAP Motion capture (data) MRI Magnetic resonance imaging
Urine-activated paper batteries for biosystems

The first urine-activated laminated paper batteries have been demonstrated and reported in this paper. A simple and cheap fabrication process for the paper batteries has been developed which is compatible with the existing plastic laminating technologies or plastic molding technologies. In this battery, a magnesium (Mg) layer and copper chloride (CuCl) in the filter paper are used as the anode and the cathode, respectively. A stack consisting of a Mg layer, CuCl-doped filter paper and a copper (Cu) layer sandwiched between two plastic layers is laminated into the paper batteries by passing through the heating roller at 120 °C. The paper battery is tested and it can deliver a power greater than 1.5 mW. In addition, these urine-activated laminated paper batteries could be integrated with bioMEMS devices such as home-based health test kits providing a power source for the electronic circuit.
Optimal Target Placement Strategy for Improved Pose Estimation Accuracy

This paper presents a method of improving the stability of non-linear iterative vision algorithms. A calibrated charged coupled device camera processes video imagery of moving space objects. A number of targets with known coordinates are attached to the surface of the object. The pose, the translation, and the attitude of the object with respect to the camera is computed iteratively. The cost function is parameterized by Euler angles. The proposed procedure estimates the optimal target locations within the area of interest in the 3D object space. The optimal configuration delivers the minimized condition number of the matrix of the linear system associated with the iterative algorithm. The method of optimizing target locations can be applied to iterative algorithms with other parameterizations of the cost function. It can also be applied to perform optimization of locations of targets attached to a 2D surface. RESUME
A Japanese perspective on the decline of robust technologies and changing technological paradigms in housing construction: issues for construction management research

Based on the concept of construction as a project-based economic activity, Steven Groák offered the idea of a technological paradigm to represent project-based technology fusion that is adaptive to the uncertainties embodied within construction projects. This paper discusses further research topics raised by the idea of the technological paradigm from a Japanese perspective. It verifies the effectiveness of Groák's notion by exemplifying phenomena identified in Japanese construction practices. First, the paper confirms how declining robust technologies are generating innovative activities in construction projects. Second, a ‘horizontal evolution’ case study is presented as evidence that the strategies engendered by the technological paradigm outperform those from the industrial paradigm. Then the paper identifies and focuses on the informality of project-based technology fusion. Relevant research topics are discussed, such as the unpredictability of system configuration, the integration of knowledge and know-how, and the regulatory framework for extending positive informality. It is concluded that the following topics have considerable significance for construction management research: (a) methodology to evaluate ‘robust limits’; (b) the process of project-to-project technology transfer and evolution; (c) organization formation of project-based technology fusion; and (d) regulatory framework that embodies informality to activate project-based technology fusion.
