Aging Processes of Archival Documents by Means of Quantitative �yperspectral Imaging : A Part of the �yperspectral Project at the Nationaal Archief

Presented at the Book and Paper Group session, AIC 37th Annual Meeting, May 20–23, 2009, Los Angeles, California. and Kakoulli 2006). The two techniques are in fact based on the same working principle, however, hyperspectral imag� ing provides more detailed spectral information and a bet� ter reproducibility of quantitative data if a correct calibra� tion procedure is applied. As a consequence, results extracted with a multispectral imaging system can generally be obtained also with a hyperspectral system covering the same spectral range, but not vice versa. The application of this technique on documents has shown to improve the quality and quantity of information obtained by the analysis of the data, opening new perspectives to the diagnosis and study of archival items. This paper concentrates on one particular application, name� ly the monitoring of aging processes, which represents at the moment an almost unexplored subject of using hyperspectral imaging in the field of cultural heritage. The research project is dedicated to the memory of our colleague Bihanne Wassink, who prematurely passed away on the 21st of April 2008. The majority of this contribution focuses on the challeng� es faced during the practical implementation of the technique as a monitoring tool and on the initial results of the experi� ments currently carried out. Although a brief introduction of the hyperspectral imaging technique is given here, the reading of introductory texts such as Campbell’s Introduction to Remote Sensing (2002) and Chang’s Hyperspectral Data Exploitation (2007) is suggested for a more detailed and technical descrip� tion of the technique itself.
Trust in Government Cross-Boundary Information Sharing Initiatives: Identifying the Determinants

This paper identifies a set of determinants of trust in government cross-boundary information sharing (CBI) initiatives. Although there are some studies that identify the antecedents of trust in collaboration, research about trust relationships in government interorganizational initiatives is lacking. Little attention, in particular, has been paid to the determinants of trust in government CBI. To fill this gap in the literature, our study analyzes eight separate case studies of information sharing initiatives from criminal justice and public health organizations to identify new determinants of trust. Drawing from the case analysis we present three propositions related to trust determinants in the context of CBI initiatives, specifically, clarity of roles and responsibilities, knowledge of participating organizations, and exercise of authority.
Accelerating the Development of Hardware Accelerators

ASC [1], A Stream Compiler , is designed to enable rapid development of hardware accelerators while still producin g results that match hand-crafted equivalents. An ASC program represents a dataflow system which can be seen as a stream; to avoid the difficulties often associated with behavioural synthesis, ASC allows direct implementation of a hardware design based on the programmer’s input. Stream architectures are constructed using a C++ based object oriented approach, and as shown in Figure 1, a single ASC description can target Field Programmable Gate Arrays (FPGAs) and also other accelerator platforms, such as Graphics Processing Units (GPUs) and Sony Playstation 2 vector units. Architectural differences are transparent to the pr ogrammer in a basic implementation, requiring only the selection of an appropriate target architecture. FPGAs show excellent potential as hardware accelerators for a wide class of applications. While running many times slower than modern Pentium-type processors, the massive fine-grained parallelism and many independent memory buses of FPGAs can permit order-of-magnitude speed-ups over software. However, programming FPGAs remains essentially a hardware design task and is much harder than writing software. High level synthesis tools attempt to bri dge the gap between algorithm and implementation, however the circuits that are obtained usually compare poorly with hand crafted implementations. While intended for graphics acceleration, modern GPUs are highly programmable parallel stream computation engines [4] and increasingly suitable for general computatio n [3]. The Sony Playstation 2 processor contains two programmable vector units that can execute independently, the abil ity of this system to accelerate applications is thus indicativ e of the potential of upcoming similar architectures such as Cel l. Through targeting multiple different acceleration architectures from a common description, we can compare the performance of each architecture for a particular algorith m. Once the best accelerator architecture has been selected, a rchitecture specific extensions can be used to further optimi se the implementation. Developer access to multiple levels in the design hierarchy offers the ASC programmer great flexibility of implementation when required, permitting optimisation at the al GPU PS2 ASC GPU ASC ASC PS2
Phrase Extraction models used for Entity Salience Detection

In this thesis, entity salience detection is researched and the publicly available WikiNews dataset is augmented with phrases information per document-entity pair. The phrases are then used together with positional encodings to determine the salience of a given entity for a document-entity pair. The results are compared to the frequently used positional baseline for entity salience and pointers are given for future research directions. Besides that, an end-to-end differentiable phrase extraction and entity salience detection model is implemented and directions for improving this model are given.
EchoTrack: Acoustic device-free hand tracking on smart phones

This paper explores the limits of acoustic ranging on smart phone in the scenario of device-free hand tracking. Tracking the hand is challenging since it requires continuously locating the moving hand in the air with fine resolution. Existing work on hand tracking relies on special hardware or requires users hold the mobile device. This paper presents EchoTrack, which continuously locates the hand by leveraging mobile audio hardware advances without special infrastructure supported. EchoTrack measures the distance from the hand to the speaker array embedded in smart phone via the chirp's Time of Flight (TOF). The speaker array and hand yield a unique triangle. The hand can be located with this triangular geometry. The trajectory accuracy can be improved with the method of Doppler shift compensation and trajectory correction (i.e., roughness penalty smoothing method). We implement a prototype on smart phone and the evaluation shows that EchoTrack can achieve tracking accuracy within about three centimeters of 76% and two centimeters of 48%.
Mathematik Pattern Formation of Magnetic Nanoparticles on Surfaces

Magnetic nanoparticles on a surface form a pattern under the influence of an applied external magnetic field. This thesis encompasses the derivation of a new mathematical model for this pattern formation, its detailed analytical treatment and numerical simulation. The obtained model combines the concepts of micromagnetism with a particle distribution function first introduced by Cahn and Hilliard. The model takes into account the underlying physical forces and energies. The existence of a minimum of the free energy is proved by means of the direct method. For numerical simulation, the problem is considered as a constraint global minimization problem. The simulation results are in good agreement with the experimental data and therefore support the derived model.
Correlated Fading Channel Simulator Based on the Overlap-Save Method

A fading channel emulator particularly suited for simulations of broadband communication systems is investigated. It is based on the overlap-save (OLS) method, traditionally used for efficient convolution. The resulting emulator shows a statistical accuracy comparable to the best known state-of-the-art techniques while greatly reducing complexity in terms of memory requirements. Therefore, it enables real-time simulation and makes the model particularly appealing for a hardware implementation. In addition, the introduction of an OLS-based interpolator enables simulation of very low Doppler frequencies with a high statistical precision.
Fast and optimized task allocation method for low vertical link density 3-Dimensional Networks-on-Chip based many core systems

The advantages of moving from 2-Dimensional Networks-on-Chip (NoCs) to 3-Dimensional NoCs for any application must be justified by the improvements in performance, power, latency and the overall system costs, especially the cost of Through-Silicon-Via (TSV). The trade-off between the number of TSVs and the 3D NoCs system performance becomes one of the most critical design issues. In this paper, we present a fast and optimized task allocation method for low vertical link density (TSV number) 3D NoCs based many core systems, in comparison to the classic methods as Genetic Algorithm (GA) and Simulated Annealing (SA), our method can save quite a number of design time. We take several state-of-the-art benchmarks and the generic scalable pseudo application (GSPA) with different network scales to simulate the achieved design (by our method), in comparison to GA and SA methods achieved designs, our technique can achieve better performance and lower cost. All the experiments have been done in GSNOC framework (written in SystemC-RTL), which can achieve the cycle accuracy and good flexibility.
Merits of Organizational Metrics in Defect Prediction: An Industrial Replication

Defect prediction models presented in the literature lack generalization unless the original study can be replicated using new datasets and in different organizational settings. Practitioners can also benefit from replicating studies in their own environment by gaining insights and comparing their findings with those reported. In this work, we replicated an earlier study in order to investigate the merits of organizational metrics in building defect prediction models for large-scale enterprise software. We mined the organizational, code complexity, code churn and pre-release bug metrics of that large scale software and built defect prediction models for each metric set. In the original study, organizational metrics were found to achieve the highest performance. In our case, models based on organizational metrics performed better than models based on churn metrics but were outperformed by pre-release metric models. Further, we verified four individual organizational metrics as indicators for defects. We conclude that the performance of different metric sets in building defect prediction models depends on the project's characteristics and the targeted prediction level. Our replication of earlier research enabled assessing the validity and limitations of organizational metrics in a different context.
New Fieldsites, New Methods: New Ethnographic Opportunities

As the rapid rate of the adoption and normative use of information technologies accelerates, sociologists must expand the sociological imagination to explore a host of questions related to mediated communication. From Twitter to YouTube, the media convergence anticipated at the close of the millennium is coming into being. Blogs, vlogs, Web browsing, e-mail, and old time television, radio, and phone are all increasingly accessible via digital technologies. Furthermore, not only can we consume these digital media, but we can now produce them easily and quickly. Yet, sociological methods have not kept pace with the profound changes in communication ensuing from the Information Revolution. Although the quotidian use of new media continues to grow by leaps and bounds, there is little consensus on how we can best collect and analyze new media data. This chapter begins to address these issues by examining how ethnographic methods have been adapted to explore new media and digital communication. We fi nd that three central tensions have shaped the adoption of ethnographic methods in new media environments since the advent of cyberethnography in the mid 1990s. The three tensions that we identify and discuss are the character of mediated interaction (e-mail, IM, blogging, texting, etc.) as a social process, text as interaction, and the relationship between the observer and the observed. Our analysis draws upon both the current work in the fi eld and foundational works that established cyberethnography as a legitimate methodological undertaking. Each section presents a history of salient texts detailing methodological growth and innovation. We bring these texts together to close each section with an eye to methodological and ethical implications under the heading “Stories from the Field. ” This section provides analysis of challenges in methodological adaptation and related ethical concerns that will be of increasing importance vis-a-vis user-driven content. We close our chapter with a review of how the strengths of traditional ethnography are especially suited to examine future waves of digital phenomena. In evaluating the commonalities between traditional and mediated ethnographic practice, we argue that although new twists in the evolution of the Internet may require ethnographers to continually adapt their methodological tool kits, they will not reduce the salience of the method.
ESTIMATION OF MUNICIPAL SOLID WASTE HEATING VALUE IN GREECE IN THE FRAME OF FORMULATING APPROPRIATE SCENARIOS ON WASTE TREATMENT

Prevention of waste production at source, recycling of packaging waste and processing the organics are the main parts of the Hellenic waste management strategy. In the meanwhile recycling of packaging wastes may be compatible with incineration within integrated waste management systems. In order to estimate and calculate the energy potential of the Municipal Solid Wastes a mathematical model was structured taking into consideration the existing legislation and infrastructure on waste management plants and their residuals. Initial goal of this paper was the formulation of an appropriate model for forecasting the waste generation till 2030 taken into account the restrictions of the Landfill Directive 1999/31/EC. Afterwards, the recycling impact and the organic waste diversion in the heating value of the MSW were investigated.

Certificate-free collaborative key agreement based on IKEv2 for IoT

End to end security in IoT is becoming a challenging issue in the upcoming smart world. Providing security in a heterogeneous environment is a critical factor when the devices are resource constrained in nature. In this work, a novel certificate-less collaborative key agreement technique has been proposed for IoT, where the computationally heavy tasks are handed over to unconstrained nodes. The receiver agrees upon the secret key, based on the collaborative values from the constrained(sender) and the unconstrained node. This algorithm is a variant of IKEv2 key agreement protocol used in the current scenario. The algorithm is tested with the tool Scyther, which is a automatic security verification tool.
Coupled nitrogen and oxygen isotope measurements of nitrate along the eastern North Pacific margin

Water column depth profiles along the North Pacific margin from Point Conception to the tip of Baja California indicate elevation of nitrate (NO3−) 15N/14N and 18O/16O associated with denitrification in the oxygen‐deficient thermocline waters of the eastern tropical North Pacific. The increase in δ18O is up to 3‰ greater than in δ15N, whereas our experiments with denitrifier cultures in seawater medium indicate a 1:1 increase in NO3− δ18O and δ15N during NO3− consumption. Moreover, the maximum in NO3− δ18O is somewhat shallower than the maximum in NO3− δ15N. These two observations can be summarized as an “anomaly” from the 1:1 δ18O‐to‐δ15N relationship expected from culture results. Comparison among stations and with other data indicates that this anomaly is generated locally. The anomaly has two plausible interpretations: (1) the addition of low‐δ15N NO3− to the shallow thermocline by the remineralization of newly fixed nitrogen, or (2) active cycling between NO3− and NO2− (coupled NO3− reduction and NO2− oxidation) in the suboxic zone.
Directed Spectral Graph Theory : Sparsification and Asymmetric Linear System Solver

This paper is our report for the Advanced Algorithm class final project. In this report, we study fast algorithms for solving directed Laplacian linear systems. A recent body of work by Cohen et al. has focused on introducing a novel notion of spectral approximation for directed graphs. They provide a general framework for solving asymmetric linear systems using the notion of spectral approximation and show how to solve directed Laplacian linear systems associated with Eulerian Graphs in almost-linear-time. In this final report, we present the general framework for solving linear systems of directed Laplacian, with focus on the key theorems and algorithms in paper [CKP16a] and the related prior work in [CKP16b]. We hope this project opens the door for our studies and research into directed spectral graph theory, and that this final project will serve as a brief technical report for our fellow classmates and researchers in the spectral graph research community.
To Docker or Not to Docker: A Security Perspective

The need for ever-shorter development cycles, continuous delivery, and cost savings in cloud-based infrastructures led to the rise of containers, which are more flexible than virtual machines and provide near-native performance. Among all container solutions, Docker, a complete packaging and software delivery tool, currently leads the market. This article gives an overview of the container ecosystem and discusses the Docker environment's security implications through realistic use cases. The authors define an adversary model, point out several vulnerabilities affecting current Docker usage, and discuss further research directions.
Prediction of Survival in Infants with Congenital Diaphragmatic Hernia Based on Stomach Position, Surgical Timing, and Oxygenation Index

Abstract Objective To identify characteristics predictive of survival of patients with congenital diaphragmatic hernia (CDH). Study Design Retrospective analysis of clinical characteristics including severity of lung disease measured by oxygenation index (OI) associated with single-center survival in CDH patients (n = 81) from 1992 to 2008. Data were analyzed using univariate and multivariable logistic regression, effect plots, and receiver operating characteristic (ROC) plots. Results No patient died if the stomach was located in the abdomen. A left thoracic stomach position predicted decreased survival with ROC area under the curve (AUC) = 0.70. OI of ≤26 averaged over the first 12 hours of life predicted ≥50% survival for all patients, with AUC = 0.86. OI effect plots allow prediction of survival over a continuous OI range. No patient survived if mean OI was >51 in the first 12 hours of life. Delaying surgery for a median of 6 days improved survival probability for all patients with presurgery OI values ≤51. Conclusion Position of the stomach in the abdomen, delayed surgery, and less severe cardiopulmonary disease during the first 12 hours of life, as measured by mean OI, predicted improved survival probability among patients with CDH. Our CDH model, using mean OI, permits specific individual prediction of survival probability over a range of OI values.
Award Number: DAMD17-03-1-0325 TITLE: p190-B, A Novel RhoGAP, In Mammary Gland Development and Breast Cancer Progression

p190-B RhoGAP (p190-B, also known as ARHGAP5) has been shown previously to play an essential role in ductal morphogenesis in the postnatal mammary gland. Expression of p190-B is detected at E12.5 in the epithelium of the mammary anlage. Here we report that embryos with a homozygous p190-B gene deletion exhibit major defects in embryonic mammary bud development including smaller bud size, fewer p63-positive cells, and display characteristics of impaired mesenchymal proliferation. IGF-1R null embryos also contain similar small mammary buds and a loss of p63-staining cells. However, unlike the p190-B null embryos, the IGF-1Rhomozygous embryos did not display similar mesenchymal defects. Since p190-B and IGF signaling intersect at the level of the IRS proteins, we examined IRS1/2 double knock-out embryonic mammary buds. We found that IRS1/2 double knock-out embryos exhibit major defects similar to those observed in the p190-B null embryos. Importantly, like the p190-B deficient buds, the proliferation of the IRS1/2 null mesenchyme is impaired. These results indicate that p190-B and IRS proteins acting possibly through IGF-1R and integrin signaling are critical for the migration of epithelial progenitors as well as the ensuing epithelial-mesenchymal interactions necessary to sustain mammary bud development and morphogenesis.
