Neighbours at the Gate: Exploration of Alternative Approaches to Refugee (Re)settlement and Integration in the Netherlands

In the Netherlands and Europe, there exist approaches to refugee (re)settlement where asylum seekers face long waiting periods, in large-scale centres often isolated from Dutch society, with little-to-no opportunity to structure their day or participate in activities which bring meaning to their lives. These activities, which bring meaning people’s lives are termed occupations in the occupational therapy and occupation science literature. When the context hinders the opportunity to engage in these meaningful occupations, one experiences a situation of occupational injustice. These approaches taken in the Netherland and internationally creates the state of occupation injustice, this lack of ability to engage in meaningful activities, and this is turn has been documented to have negative effects on refugees health, well-being, identity and eventual inclusion in society.Parallel to these standard approaches in the Netherlands, are alternative approaches to refugee resettlement and integration. These alternatives are oftenbeing facilitated by charities, community-based organizations and citizen initiatives. Alternative programs currently aim to counter the government programs and focus on safe passages, for vulnerable populations, with an emphasis on early inclusion in society, community placement, sponsorship, and integration from the time of arrival. These alternative programs claim to address the issues of lack of meaningful engagement and isolation as currently seen in standard procedures, thereby claiming to improve integration, inclusion and wellbeing.This research aims to explore the lives and experiences of both the individuals living in, as well as the individuals facilitating these alternative programs. The research will explore how these programs are situated in and/or actively negotiating the broader context of refugee programs and policies in the Netherlands. This exploration will include the perspectives of the multiple actors involved, including service users and service providers, using a participatory methodology.Through exploring the perspectives on alternative programs through a participatory evaluation format, we are able to explore these programs as they are described, evaluated and experienced by theservices users themselves. This allows for a grounded understanding of the programs and their further potential.

Resource-Efficient Image Buffer Architecture for Neighborhood Processors

Neighborhood image processing operations on Field Programmable Gate Array (FPGA) are considered as memory intensive operations. A large memory bandwidth is required to transfer the required pixel data from external memory to the processing unit. On-chip image buffers are employed to reduce this data transfer rate. Conventional image buffers, implemented either by using FPGA logic resources or embedded memories are resource inefficient. They exhaust the limited FPGA resources quickly. Consequently, hardware implementation of neighborhood operations becomes expensive, and integrating them in resource constrained devices becomes unfeasible. This paper presents a resource efficient FPGA based on-chip buffer architecture. The proposed architecture utilizes full capacity of a single Xilinx BlockRAM (BRAM36 primitive) for storing multiple rows of input image. To get multiple pixels/clock in a user defined scan order, an efficient duty-cycle based memory accessing technique is coupled with a customized addressing circuitry. This accessing technique exploits switching capabilities of BRAM to read 4 pixels in a single clock cycle without degrading system frequency. The addressing circuitry provides multiple pixels/clock in any user defined scan order to implement a wide range of neighborhood operations. With the saving of 83% BRAM resources, the buffer architecture operates at 278 MHz on Xilinx Artix-7 FPGA with an efficiency of 1.3 clock/pixel. It is thus capable to fulfill real time image processing requirements for HD image resolution (1080 × 1920) @103 fcps.

A novel validation approach for validating the simulation model of a passengers' airport terminal

In this paper we propose a novel approach for validating a simulation model for a passengers' airport terminal. The validation approach is based on a "historical data" and "model-to-model" validation approach, and the novelty is represented by the fact that the model used as comparison uses historical data from different data sources and technologies. The proposed validation approach , which is presented as part of the IMHOTEP project, implements various data fusion and data analytics methods to generate the passenger "Activity-Travel-Diary", which is the model that is then compared with the results from the simulation model. The data used for developing the "Activity-Travel-Diary" comes from different sources and technologies such as: passengers data (personal mobile phone, apps), airport data (airport Wi-Fi, GPS, scanning facilities), and flight Information (flight schedules, gate allocation etc.). The simulation model is based on an agent-based simulation paradigm and includes all the passengers flows and operations within a terminal airport. The proposed validation approach is implemented in a real-life case study, Palma de Mallorca Airport, and preliminary results of the validation (calibration) process of the simulation model are presented.

Deep learning with Python for crack detection

An illustrative non-technical review was published on Towards Data Science regarding our recent Journal paper “Automatic crack classification and segmentation on masonry surfaces using convolutional neural networks and transfer learning”.While new technologies have changed almost every aspect of our lives, the construction field seems to be struggling to catch up. Currently, the structural condition of a building is still predominantly manually inspected. In simple terms, even nowadays when a structure needs to be inspected for any damage, an engineer will manually check all the surfaces and take a bunch of photos while keeping notes of the position of any cracks. Then a few more hours need to be spent at the office to sort all the photos and notes trying to make a meaningful report out of it. Apparently this a laborious, costly, and subjective process. On top of that, safety concerns arise since there are parts of structures with access restrictions and difficult to reach. To give you an example, the Golden Gate Bridge needs to be periodically inspected. In other words, up to very recently there would be specially trained people who would climb across this picturesque structure and check every inch of it.

Integrated multimodal airport operations for efficient passenger flow management

Predictive models and decision support toolsallow information sharing, common situational awarenessand real-time collaborative decision-making betweenairports and ground transport stakeholders. To supportthis general goal, IMHOTEP has developed a set of modelsable to anticipate the evolution of an airport’s passengerflows within the day of operations. This is to assess theoperational impact of different management measures onthe airport processes and the ground transport system. Twomodels covering the passenger flows inside the terminal andof passengers accessing and egressing the airport have beenintegrated to provide a holistic view of the passengerjourney from door-to-gate and vice versa.This paper describes IMHOTEP’s application at two casestudy airports, Palma de Mallorca (PMI) and London City(LCY), at Proof of Concept (PoC-level) assessing impactand service improvements for passengers, airport operatorsand other key stakeholders.For the first time onemeasurable process is created to open up opportunities forbetter communication across all associated stakeholders.Ultimately the successful implementation will lead to areduction of the carbon footprint of the passenger journeyby better use of existing facilities and surface transportservices, and the delay or omission of additional airportfacility capacities.
