Design and In Vitro Validation of an Orthopaedic Drill Guide for Femoral Stem Revision in Total Hip Arthroplasty

Objective: Cemented total hip arthroplasty (THA) demonstrates superior survival rates compared to uncemented procedures. Nevertheless, most younger patients opt for uncemented THA, as removing well-fixed bone cement in the femur during revisions is complex, particularly the distal cement plug. This removal procedure often increases the risk...

Institutional form (blueprints) and institutional function (process): Theoretical reflections on property rights and land

This paper is concerned with the question how we should understand cases on property rights in general, and on land economics in particular, in which a remarkable level of growth (or other measures of institutional performance) is combined with so-called ‘perverse’ institutions. That is to say institutions that are not proposed by the neoliberal...

Information and communication technology enabling partnership in person-centred diabetes management: Building a theoretical framework from an inductive case study in the Netherlands

Objectives The aim of this paper is to construct a theoretical framework for information and communication technology (ICT)-enabled partnership towards diabetes management. Design We conducted an inductive case study and held interviews on the development and use of an artificial pancreas (AP) system for diabetes management. Setting The study...

Partial safety factors for berthing velocity and loads on marine structures

Design methods for marine structures have evolved into load and resistance factor design, however existing partial safety factors related to berthing velocity and loads have not been verified and validated by measurement campaigns. In this study, field observations of modern seagoing vessels berthing in Bremerhaven, Rotterdam and Wilhelmshaven...

A Shazam-like Household Water Leakage Detection Method

Waternomics is a European Union-funded research project aspiring to develop and introduce Information and Communication Technology (ICT) as an enabling technology to manage water as a resource, increase end-user conservation awareness, affect behavioural changes and avoid water losses through leak detection. Existing leakage detection methods...

Berthing velocity of large seagoing vessels in the port of Rotterdam

While ships evolve constantly, berthing velocity curves developed during the 1970s are still embedded in the design of marine structures. This paper discusses the interpretation of new berthing records of modern large seagoing vessels collected in the port of Rotterdam. Berthing velocities of several types of vessels at various berths and...

Integration of data validation and user interface concerns in a DSL for web applications

Data validation rules constitute the constraints that data input and processing must adhere to in addition to the structural constraints imposed by a data model. Web modeling tools do not make all types of data validation explicit in their models, hampering full code generation and model expressivity. Web application frameworks do not offer a...

Aligning modes of organization with technology: Critical transactions in the reform of infrastructures

We address the alignment of technology and modes of organization in infrastructures in the context of their reform. Since infrastructures are characterized by strong technical complementarities, we explore the resulting ‘critical technical functions that need to be performed in order to guarantee the expected technical performance of the system....

Modeling diffusion and phase transitions by a uniform-acceptance force-bias Monte Carlo method

The uniform-acceptance force-bias Monte Carlo (UFMC) method [G. Dereli, Mol. Simul. 8, 351 (1992)] is a little-used atomistic simulation method that has strong potential as alternative or complementary technique to molecular dynamics (MD). We have applied UFMC to surface diffusion, amorphization, melting, glass transition, and crystallization,...

Code generation by model transformation: A case study in transformation modularity

The realization of model-driven software development requires effective techniques for implementing code generators for domain-specific languages. This paper identifies techniques for improving separation of concerns in the implementation of generators. The core technique is code generation by model transformation, that is, the generation of a...
