This report summarizes the result of a graduation project on the behaviour of a harbour tugmaster and his tug. First, research is described which has been conducted into the behaviour of a tugmaster. Based on this study a model has been developped to generate realistic tracks of a tugboat. This can be used to generate automatic tugboat...

Actief sluitende handprothesen zijn prothesen waarbij de kunsthand wordt dichtgeknepen door de elleboog aan gehandicapte zijde te buigen. De knijpkracht wordt hierbij door spierkracht (biceps) verzorgd. Bij dit type prothese is de knijpkracht doseerbaar en kan de geleverde knijpkracht indirect gevoeld worden, de bedieningskracht is een maat voor...

Dit rapport beschrijft een model voor het genereren van realistische achtersleepbootassistentie. Dit model kan gebruikt worden voor het aan sturen van een gesimuleerde sleepboot op een "Full Mission Bridge Simulator". Het model genegeerd natuurgetrouwe banen voor een Azimunth tractor sleepboot. Het model past de positie en de heading van de...

Het doel van deze afstudeeropdracht was om de in theoretische voorstudies voorgestelde veiligheidsindicatoren voor het beoordelen van simulatieruns te valideren met behulp van expertmeningen. Na observatie van simulatieruns en interviews met experts is gekozen om de Closest point of Approach (CPA) indicator en de Reserved Control Indicator (RCI)...

The Wilmer Rotational Instant Seizing Tentacle (WRIST) is a Voluntary Closing (VC) hook prosthesis for transradial amputees, developed by the WILMER Group at the Delft University of Technology in the Netherlands. Dissatisfaction with the currently used bodypowered arm prostheses, expressed by patients and members of the WILMER group, led to a...

In this paper a possible Operator Support System (OSS) for vessel traffic management on the basis of vessel traffic simulation is presented. A proposal is made for a tool to give the Vessel Traffic Service (VTS) operator a better understanding in the development of vessel traffic situations and in advance identification of unsafe situations. An...

In dit rapport wordt het ontwerp van een open fitting voor onderarmprothesen beschreven. De fitting van de prothese is het deel van de prothese dat externe krachten overbrengt op de arm (en andersom). Als eerste wordt een overzicht gegeven van de externe krachten en momenten die de prothese moet kunnen opvangen. Vervolgens worden de...

This research project on the field of human machine systems, especially human control of complex systems has as objective to find a relation between interface complexity and workload and a relation between interface complexity and performance. Complexity is split into three parts: system complexity, task complexity and interface complexity. The...

De handprothesen die op de markt zijn voldoen niet aan de eisen van de gebruikers, dit zijn: goede cosmetiek, draagcomfort en bedieningsgemak. Om tot een goede bedieningsgemak te komen is kracht en plaatsterugkoppeling belangrijk. Cosmetiek en terugkoppeling kunnen goed zijn bij lichaamsbekrachtigde actief sluitende prothesehanden, mits aan de...

The neuromusculoskeletal model of this study was built to better understand the mechanisms behind negative position and velocity feedback gains as identified in human postural control (Van der Helm et al.,2002). Specifically, causes were sought which could explain: a) why Reflex Sympathetic Dystrophy (RSD) patients with tonic dystonia are unable...

Tumor vascular networks play an important role in various treatments of cancer. Tumor vascular morphology and hemodynamics are known to be different from normal healthy vascular networks. For improvement of treatment, the origins of these differences need to be understood. Differences in morphology and hemodynamics might be due to changes in...

This thesis reports the design and evaluation of a remote control interface, aimed to simulate the axial forces at the needle during percutaneous interventions on the lower area of a patient's spinal cord. For evaluation, an in vitro experiment set up of different types of artificial tissues mimicking the varying types of tissue found on the...

This paper describes a new method to identify information overload problems in an alarm system. This method can also be used to become aware of the performance of an alarm system and to present the effectiveness of alarm rationalisation. Furthermore we show that pattern detection can be used to find meaningful patterns. Furthermore this paper...

Human operators tend to make trade-offs when they are controlling complex systems. When an operator has the perception that a large increase in productivity can be obtained by safely getting round a safety provision, he is likely to do so. These so-called violations have led to several accidents in the last decades. The goals of this research...

Minimally invasive surgery (MIS) is a surgery technique that is carried out through small incisions in the skin with thin, long instruments. In order for the surgeon to see his actions with his instruments, a small camera with a light source (an endoscope) is used to look inside the person that is operated. MIS, also called laparoscopy when...

The fields of static balancing and tensegrity structures are combined into statically balanced tensegrity mechanisms. This combination results in a new class of prestressed structures that behave like mechanisms: although member lengths and orientations change, they can be deformed into a wide range of positions, while continuously remaining in...

Malignant colonic obstruction is a severe complication of primary colorectal carcinoma. Patients presenting this clinical condition develop tumors that obstruct the lumen of the intestinal tract. The treatment of this medical complication is aimed to re-establish the normal pass of fecal mass through the colon. One of the current treatments...

Surgical processes place a heavy burden upon the finance of hospitals and should therefor be utilized effectively. Effectively, means (economically) efficient, safe for patients and personnel, and reliable for any actors (normal practice can be assumed). Rapid organizational learning is required to identify system vulnerabilities quickly and to...

Patients with foot deformation, cartilage wear or a badly healed calcaneus fracture often suffer from severe pain in the foot. After fixation of the subtalar joint, which stabilizes motion, most patients can walk without pain again. Because the curtent operation is an open approach, it is difficult to reach the entire joint space and to remove...
