| Information solutions to manage the assistance to people during natural disasters have been proposed in the literature and there is a recent proposal to handle various flooding scenarios. This paper describes a prototype based on RFID tag bracelet to manage information in an emergency shelter and food services provided to refugees. This emergency shelter is installed after occurring natural disasters (floods). First, refugees write on a RFID bracelet tag their ID (CURP), then different writing/reading are made according to services received at the emergency shelter, also food service delivery, control arrival/departure and delivery items of personal hygiene are stored in a database. We propose a partial solution to problems for controlling temporary shelters during an emergency situation, thereby improving the recording and accessing for existing aid programs offered by temporary shelters. |

| In this paper the focusing capability of a radiating aperture implementing an inward traveling wave current distribution directed along a fixed unit vector is investigated. In particular, it is shown that such a current distribution generates a field profile with its transverse component (with respect to the normal of the radiating aperture) taking the form of a zero-th order Bessel profile. As a practical implementation of the theoretical analysis, a circular-polarized (CP) Bessel beam launcher, made by a radial parallel-plate waveguide loaded with several slot pairs and arranged on a spiral pattern, is designed and optimized. The designed launcher performance agrees with the theoretical model and exhibits an excellent polarization purity. |

| This paper is written based on the need for Computerized Maintenance Management System's (CMMS) decision analysis capability to achieve world class status in maintenance management. Investigations indicate that decision analysis capability is often missing in existing CMMSs and collected data in the systems are not completely utilized. How to utilize the gathered data to provide guidelines for maintenance engineers and managers to make proper maintenance decisions has always been a crucial question. In order to provide decision support capability, the aim of this paper is to provide and examine three different decision making techniques which can be linked to CMMS and add value to collected data. This research has been conducted within a global project in a large manufacturing site in Sweden to provide a new maintenance management system for the company. The data from the main studies were collected through document analysis complemented by discussions with maintenance engineers and managers at the case company to verify the data. Methods including a Multiple Criteria Decision Making (MCDM) technique called TOPSIS, k-means clustering technique, and one decision making model borrowed from the literature were used. The results indicate the most appropriate maintenance decision for each of the selected machines/parts according to factors such as frequency of breakdowns, downtime, and cost of repairing. The paper concludes with a comparison of results obtained from the different decision making techniques and also a discussion on possible improvements needed to increase the capability of the maintenance decision making models. |

| This paper propose a metadata schema to preserve the semantics of cultural heritage (CH) objects. A widely used standard of CH metadata is already provide by CIDOC-CRM which has been approved as an ISO 21127 in 2006. However, mapping CH attributes to CIDOC-CRM entities needs to be done carefully since the metadata could be published as open data. In order to enrich the spatial information of CH objects, we linked the metadata with geographic features in open geographic dataset Geonames. In the experiment results, the metadata and open linked data seems to be successfully implemented and can be used to solve more specific query about CH objects relates to their spatio-temporal relationships |

| In the field of nonlinear model predictive control (NMPC) under uncertainty we use a robustification approach based on a scenario tree formulation. This approach is known to be less conservative than worst-case approaches. A main challenge of scenario tree NMPC in high-dimensional uncertainty spaces is the exponential growth of the number of scenarios for possible parameter realizations. Hence, the solution of the resulting optimization problem in every NMPC iteration becomes a bottleneck for the computation. We have to solve the problem with fast numerical methods to ensure real-time applicability of scenario tree NMPC. By a multiple shooting discretization we discretize the optimal control problems of an NMPC iteration to obtain a sequence of Nonlinear Programs that we solve by a real-time feasible variant of Sequential Quadratic Programming (SQP). Every single Quadratic Programming problem (QP) exhibits a particular structure originating from the scenario tree. We use a dual decomposition approach on the non-anticipativity constraints from the scenario tree formulation to decouple the large-scale QP into many smaller QPs that each correspond to one scenario in the scenario tree. Within an outer level non-smooth Newton iteration in the dual space of the coupling constraints, the decoupled scenario QPs can be solved in a massively parallel fashion. In the final part of this contribution we present numerical results for NMPC with large scenario trees. |

| At Baylor University we have done engineering service projects in the developing world for about 10 years. As we have assessed both our successes and failures, we realized that to make the projects sustainable, they had to be done with local partners over many years. Our level of engagement with the local people has had a significant impact upon the sustainability of the projects. Our model for how best to do this engagement has changed as we have learned from experience. We are now working in Haiti, partnering with a local non-profit group that has been working in Haiti for 20 years. This helped us earn credibility in the local community. In May 2013 and May 2014 we did solar projects that were well received. We also did projects involving water quality testing and water purification. This work has great promise for being sustainable, for it is working with (not for) the local people and is close enough to the United States so that its costs are more manageable. In addition to creating sustainable projects, we need to develop ways to make the program at our university sustainable. This involves doing several things to help students stay motivated to work in this area. In addition to our trips we have created several cocurricular activities (such as a book club discussing Humanitarian Engineering). We have also made curricular changes, such as introducing an alternative engineering ethics course called Ethics for International Service. We have created a Humanitarian Engineering concentration within our generic engineering major. Students in this concentration will take courses in six topics: people (and culture), economics, development, energy, food/water, and an international service learning class. When coupled with their engineering skills, these courses will help our students be more successful while working in the developing world. |

| Persistent organic pollutants (POPs) are bioaccumulative and environmentally persistent substances. POPs cannot be decomposed by conventional water treatments. For this reason, a new treatment method is required. Nano-seconds (ns) pulsed discharges enable higher energy efficiencies of plasma processing. Its advantages have been already performed at gas phase treatment such as NOx treatment and ozone generation. On the other hand, there are few reports on the water treatment using ns discharge plasmas. In this study, we tried to decompose the organic pollutants using ns method by spraying wastewater into gas phase plasma region. The discharge reactor was coaxial cylindrical geometry, and the treated wastewater was circulated and continuously treated in the reactor. The time course of pH and concentration of total organic carbon (TOC) in the wastewater were evaluated at different applied voltages. From the results, the decrease of TOC in the wastewater was observed together with pH at ns discharge treatment. The experimental results showed that the ns pulsed discharge plasma can decompose TOC in the wastewater and has discoloration effect. |

| The identification of structured state-space model has been intensively studied for a long time but still has not been adequately addressed. The main challenge is that the involved estimation problem is a non-convex (or bilinear) optimization problem. This paper is devoted to developing an identification method which aims to find the global optimal solution under mild computational burden. Key to the developed identification algorithm is to transform a bilinear estimation to a rank constrained optimization problem and further a difference of convex programming (DCP) problem. The initial condition for the DCP problem is obtained by solving its convex part of the optimization problem which happens to be a nuclear norm regularized optimization problem. Since the nuclear norm regularized optimization is the closest convex form of the low-rank constrained estimation problem, the obtained initial condition is always of high quality which provides the DCP problem a good starting point. The DCP problem is then solved by the sequential convex programming method. Finally, numerical examples are included to show the effectiveness of the developed identification algorithm. |

| Smart environments are interactive spaces that offer quality of life for users. Considering this definition, our study aims to investigate papers containing projects and/ or evaluation of smart environments in the context of smart cities, using gesture-based interaction applied in health solutions. Our approach is a systematic review of the literature that examined the following databases: IEEE Xplore, ScienceDirect, Springer, CiteSeerX and Google Scholar, from November 13 to December 18, 2014. From 212 studies identified, only 12 were in agreement with the eligibility criteria. After analysis of the papers, the usability of smart gesture-based environments was discussed considering the medical area, presenting possible benefits for healthcare. |

| Differences of depressed and normal peoples' behavior in identification tasks is explored for a long time in cognitive science experiments. Words, pictures and emotional faces were introduced into psychological experiments in latest studies. However, usually the priming effect of images is used frequently, which is not according with people's common sense. In this paper, competing effect is introduced. We selected two kinds of background scenes based on image voting results: negative scenes and positive scenes for testing. Correspondingly, positive faces and negative faces were also utilized as testing images. Three experiments were designed considering both the initiation and the distraction effect of background, especially the third experiment considering both priming effect and competing effect simultaneously. According to data analysis results, there exists more significant discrepancy considering competing effect in identification speeds and identification discriminations between depressed people and normal people. |

| Non-negative Matrix Factorization (NMF) aims to find two non-negative matrices whose product approximates the original matrix well, and is widely used in clustering condition with good physical interpretability and universal applicability. Detecting communities with NMF can keep non-negative network physical definition and effectively capture communities-based structure in the low dimensional data space. However some NMF methods in community detection did not concern with more network inner structures or existing ground-truth community information. In this paper, we propose a novel pairwisely constrained non-negative symmetric matrix factorization (PCSNMF) method, which not only consider symmetric community structures of undirected network, but also takes into consideration the pairwise constraints generated from some ground-truth group information to enhance the community detection. We compare our approaches with other NMF-based methods in three social networks, and experimental results for community detection show that our approaches are all feasible and achieve better community detection results. |

| To facilitate, enhance or improve mutual work, many people are sharing resources through networks in order. Information sharing is basically used to support the collaborative work and it also represents the basis for typical design aspects of groupware applications. Such as: floor control, group memory, shared objects replication and sessions and users management. The sharing information scenarios have brought new challenges to Mobile Networks using mobile technology. This paper presents a community network based sharing data among members on wireless network by ant colony optimization (ACO) technique an artificial ant colony capable of finding the shortest path source member to connected member. To reduce the routing overhead and networking cost is the main goal of design of the protocol. |

| Lasing threshold conditions have been analyzed in deep-UV (DUV) multiple-QW (MQW) III-nitride laser diode (LD) structures with different QW confinement depth. Shallow QWs with smaller internal polarization fields reveal better QW emission characteristics including lower QW transparency population and higher differential gain. In MQW LD structures, however, the high-gain operation of shallow QWs is hindered by insufficient QW injection due to increased carrier leakage from shallow-QW active region. Deep active QWs can attain higher operational populations and provide for higher LD optical gain; however, LDs designed with deeper active QWs suffer from MQW population non-uniformity due to increased inhomogeneity of carrier injection. Underpumped deep QWs reduce the total modal gain of the LD structure thus deteriorating the lasing threshold and LD power conversion (wall-plug) efficiency. |

| This paper studies the identification problem of a gain system using both input and output quantized data. Specifically, the system input and the output are separately quantized into one bit before sent to a remote estimator, which generates a recursive algorithm to identify the system. If the random input is an independent and identical Gaussian process, we develop the identification algorithms respectively by using the empirical measure and the maximum likelihood estimation, which is given in a recursive form by the EM and quasi-Newton iterations. Finally, simulations are included to validate theoretical results. |

| Magnetic levitation is one of the solutions for high-precision positioning systems due to its non-contact characteristic. Magnetic bearings have the potential of replacing the air bearings that are used in the semiconductor industry in which the vacuum environment is increasingly required. For the traditional z-actuators in the multi-DOF fine stage, a continuous power loss is inevitable because the z-actuators are required to support the moving mass. Therefore, the heat form the coils will cause the temperature rise and structural distortion, which both deteriorate the positioning accuracy. A good solution is to support the moving mass by passive magnetic force. However, the major difficulty in using passive magnetic force is the highly position-dependent characteristic. From the aspects of positioning accuracy and vibration isolation, the stiffness that are defined as the position dependency of the magnetic force should be kept as low as possible. To date, the main reasons of the stiffness error between theoretical analysis and experiment results are ascribed to assembling error and machining tolerance. However, it is not entirely true for the low-stiffness applications. In this paper, the essential reason causing the stiffness error is analyzed and a new method to realize low stiffness for passive magnetic levitation is proposed. |

| The purpose of this paper is to demonstrate the contributions of Quality Maintenance (QM) Pillar of TPM approach in improving the product quality in a food industry manufacturing potato chips. QM Pillar is an important initiative of TPM methodology which aims to give customer delight through defect free manufacturing. The effective TPM implementation enhances production efficiency with an ultimate aim of attaining zero breakdowns, zero losses and zero defects. The focus of QM Pillar is on eliminating non-conformances in a systematic manner and maintaining equipment to produce high quality products. The QM pillar activities in the industry remained successful in reducing the customer complaints and regulatory complaints to zero. Also, considerable reduction in number of major defects occurred and leakage problems reduced from 1.20% to 0.27%. The QM pillar targets are achieved successfully by the industry such as sustaining customer complaints at zero, reduce in-process defects by 83% and reduce cost of quality by 46%. |

| A common approach to attack the simultaneous localization and mapping problem (SLAM) is to consider factor-graph formulations of the underlying filtering and estimation setup. While Kalman filter-based methods provide an estimate for the current pose of a robot and all landmark positions, graph-based approaches take not only the current pose into account but also the entire trajectory of the robot and have to solve a nonlinear least-squares optimization problem. Using graph-based representations has proven to be highly scalable and very accurate as compared with traditional filter-based approaches. However, biased measurements as well as unmodeled correlations can lead to a sharp deterioration in the estimation quality and hence require careful consideration. In this paper, a method to incorporate biased or dependent measurement information is proposed that can easily be integrated into existing optimization algorithms for graph-based SLAM. For biased sensor data, techniques from ellipsoidal calculus are employed to compute the corresponding information matrices. Dependencies among noise terms are treated by a generalization of the covariance intersection concept. The treatment of both biased and correlated sensor data rest upon the inflation of the involved error matrices. Simulations are used to discuss and evaluate the proposed method. |

| Today, web injection manifests in many forms, but fundamentally occurs when malicious and unwanted actors tamper directly with browser sessions for their own profit. In this work we illuminate the scope and negative impact of one of these forms, ad injection, in which users have ads imposed on them in addition to, or different from, those that websites originally sent them. We develop a multi-staged pipeline that identifies ad injection in the wild and captures its distribution and revenue chains. We find that ad injection has entrenched itself as a cross-browser monetization platform impacting more than 5% of unique daily IP addresses accessing Google -- tens of millions of users around the globe. Injected ads arrive on a client's machine through multiple vectors: our measurements identify 50,870 Chrome extensions and 34,407 Windows binaries, 38% and 17% of which are explicitly malicious. A small number of software developers support the vast majority of these injectors who in turn syndicate from the larger ad ecosystem. We have contacted the Chrome Web Store and the advertisers targeted by ad injectors to alert each of the deceptive practices involved. |
