Scherer Multidemand Multidimensional KP Instances
No full textTest instance data for the 0-1 multidemand multidimensional knapsack problem (MDMKP) from the Primal Problem Instance Generator (PPIG) from Scherer et al. 2023. The instances allow for a greater range of correlation values between the profit coefficients and the coefficients for the knapsack and demand constraints. The test instances also flex the constraint tightness across each dimension. Providing a different structure than existing instances. The first 45 instances do not obey a predetermined correlation structure, while the remaining 135 instances are defined through an explicit predetermined correlation structure (Uniform(-1,1)) for each dimension of each coefficient used in the MDMKP. The .txt file attached obeys the following structure, by line.Problem number and best found objective valuenumber of variables, number of knapsack constraints, number of covering constraintsobjective function coefficientsright hand side values knapsack constraintsright hand side values covering constraintsm rows of left hand side knapsack coefficientsn rows of left hand side covering coefficientsFor any inquires contact the author at [email protected] DATASET IS ARCHIVED AT DANS/EASY, BUT NOT ACCESSIBLE HERE.

Information Retrieval for Multivariate Research Data Repositories
No full textIn this dissertation, I tackle the challenge of information retrieval for multivariate research data by providing novel means of content-based access.Large amounts of multivariate data are produced and collected in different areas of scientific research and industrial applications, including the human or natural sciences, the social or economical sciences and applications like quality control, security and machine monitoring. Archival and re-use of this kind of data has been identified as an important factor in the supply of information to support research and industrial production. Due to increasing efforts in the digital library community, such multivariate data are collected, archived and often made publicly available by specialized research data repositories. A multivariate research data document consists of tabular data with columns (measurement parameters, e.g., temperature, pressure, humidity, etc.) and rows (observations). To render such data-sets accessible, they are annotated with meta-data according to well-defined meta-data standard when being archived. These annotations include time, location, parameters, title, author (and potentially many more) of the document under concern. In particular for multivariate data, each column is annotated with the parameter name and unit of its data (e.g., water depth [m]).The task of retrieving and ranking the documents an information seeker is looking for is an important and difficult challenge. To date, access to this data is primarily provided by means of annotated, textual meta-data as described above. An information seeker can search for documents of interest, by querying for the annotated meta-data. For example, an information seeker can retrieve all documents that were obtained in a specific region or within a certain period of time. Similarly, she can search for data-sets that contain a particular measurement via its parameter name or search for data-sets that were produced by a specific scientist. However, retrieval via textual annotations is limited and does not allow for content-based search, e.g., retrieving data which contains a particular measurement pattern like a linear relationship between water depth and water pressure, or which is similar to example data the information seeker provides.In this thesis, I deal with this challenge and develop novel indexing and retrieval schemes, to extend the established, meta-data based access to multivariate research data. By analyzing and indexing the data patterns occurring in multivariate data, one can support new techniques for content-based retrieval and exploration, well beyond meta-data based query methods. This allows information seekers to query for multivariate data-sets that exhibit patterns similar to an example data-set they provide. Furthermore, information seekers can specify one or more particular patterns they are looking for, to retrieve multivariate data-sets that contain similar patterns. To this end, I also develop visual-interactive techniques to support information seekers in formulating such queries, which inherently are more complex than textual search strings. These techniques include providing an over-view of potentially interesting patterns to search for, that interactively adapt to the user's query as it is being entered. Furthermore, based on the pattern description of each multivariate data document, I introduce a similarity measure for multivariate data. This allows scientists to quickly discover similar (or contradictory) data to their own measurements.EG Graphics Dissertation Onlin
Mineral consolidants
No full textInorganic consolidants, such as ethyl silicate, nanolime and ammonium oxalate, have proven to be effective for certain materials, but each has its drawbacks. This has recently led to the investigation of hydroxyapatite (HAP) as a novel inorganic consolidant, which demonstrated excellent performance on carbonate stones. Considering that a mineral that matched calcite crystal lattice parameters even more closely than HAP would be expected to provide a consolidating action even greater than HAP, in this study aluminum phosphate (AP) was investigated as a potential new consolidant. Indeed, AP has lattice parameters differing from those of calcite by only 1%. The consolidating ability of AP was preliminarily investigated here in comparison with HAP. Both treatments were tested on artificially weathered marble samples, in the view of their application for conservation of sugaring marble. A novel method is also proposed for producing samples with near-surface damage similar to that of sugaring marble in the field. The results of the study point out that the novel weathering method is able to provide samples with tailored gradient in dynamic elastic modulus, closely resembling naturally sugaring marble. The AP treatment was found to significantly improve the dynamic elastic modulus of weathered marble, at least as efficiently as the HAP treatment investigated in this study. This confirmed the high potential of AP as a new inorganic consolidant
The Internationalists Masters of the Global Game
No full textIn this groundbreaking book, author Catherine Scherer focuses on the critical characteristics of successful global-facing professionals. She identi? es the ? ve key practices of successful “internationalists” and posits that acknowledging their unique capabilities and valuing those characteristics will have a profound effect on corporate mind-set and how global companies plan and execute the human element of their cross-border strategies. Using ? rst-person interviews and case studies, she illustrates the role of the internationalist and the results for global companies that recognize the importance of internationalists in leadership roles. Based on academic research and extensive interviews with international executives on four continents, The Internationalists identi? es the human problems common to international business ventures and analyzes them for lessons learned. From there, Scherer outlines human resources strategies for creating thoughtful and sensible international projects using the talents of those most capable of successfully carrying out cross-border ventures. A “must read” for executives, global leadership teams, senior human resources professionals, international project managers, and anyone contemplating an international career.

A comparative case study of coordination mechanisms in Design and Build BIM-based projects in the Netherlands
No full textBIM implementation can affect the project coordination mechanisms in unexpected ways, even in widely-applied project procurement structures. Apart from the chosen procurement approach, the BIM technology and the distribution of roles in the project team influence and shape the project coordination. This paper aims to explore the emerging coordination structures and processes from BIM implementation in design-build procurement. An exploratory comparative case study has been undertaken. The findings included two main coordination mechanisms: a centralized and decentralized structure and a hierarchical ver-sus participative decision-making processes. These two patterns subsequently open a debate about the rela-tions between BIM implementation and business models in AEC and particularly the emergence of specialized all-around BIM firms versus BIM-knowledgeable engineering firms.Accepted Author ManuscriptDesign & Construction Managemen

I had already read the volume, and prize the oppertunity of having as mine a copy from the author\u27s kind hands. As I wrote to our mutual friend, Mr. Vroman, I look upon Stikeen as the finest dog story that has ever come my way; and I think I have read the most of them, from John Brown to Mark Twain. I find that Mr. Vroman has also put a portrait of you in my office. I appreciate its presence here,but would prefer the original. I shall look forward with keen pleasure to an early meeting.Yours most sincerely,[illegible]04532https://scholarlycommons.pacific.edu/jmcl/31456/thumbnail.jp

Facilitating the BIM coordinator and empowering the suppliers with automated data compliance checking
No full textIn projects with Building Information Modelling (BIM), the collaboration among the various actors is a very intricate and intensive process. The various suppliers and engineers provide their input in Industry Foundation Classes (IFC), which in turn is used for design coordination. However, the IFCs have to undergo an intermediate checking process to ensure compliance with various client-set and technical requirements. The paper focuses on the potential of (semi-)automatic IFC compliance checks and discusses a relevant recent initiative in the Netherlands, according to which several IFC compliance criteria were agreed among 14 contractors. This study aims to unravel the changes induced by this development not only as to the IFC compliance checks, but also as to potentially balancing the roles between the BIM coordinator and the suppliers.Accepted Author ManuscriptDesign & Construction Managemen
