Predicting the Offender: Frequency versus Bayes

In this paper two Bayesian approaches and a frequency approach are compared on predicting offender output variables based on the input of crime scene and victim variables. The K2 algorithm, Naïve Bayes and frequency approach were trained to make the correct prediction using a database of 233 solved Dutch single offender/single victim homicide...

The unmanned underwater vehicle: An alternative for the SSK or a valuable addition?

The future of manned submarines is currently in question as a result of rapid developments in autonomy in other fields (e.g. autonomous cars). Therefore, the feasibility of an unmanned submarine, basically a large unmanned underwater vehicle (UUV), as a replacement for a conventional diesel-electric submarine (SSK), was investigated....

Reliably Assessing the Effectiveness of a Plan Using Models of Varying Fidelity and Under Time Constraints

Assessing the effectiveness of a plan, given multiple potential scenarios, is a common problem for analysts, especially in the military domain. This problem can seriously impact the safety of the people that are involved in planned missions. More precisely, the availability of multiple models, with varying levels of fidelity, leads to the...

Vermissingsopsporing: het HMF-model

Het aantal vermissingen is de laatste jaren steeds toegenomen, volgens Landelijk Bureau Vermiste Personen (De Telegraaf 2014), en het hoge aantal vereist een grote politie-inspanning. Het efficiënt en effectief aanpakken van een vermissing wordt dus alleen maar belangrijker. Dit artikel gaat in op de huidige werkwijze en problematiek bij...

Research into Underwater Defence in Stationary Operations

During the past two decades the global security situation has seen some drastic changes. The operational scope of the Royal Netherlands Navy (RNLN) has expanded from operations on the open seas to operations both on the open seas and in littoral waters. A considerable part of the relevant operations now take place outside NATO territory. This...

Ship Signature Management System: Functionality

A signature of a platform is the manner in which the platform manifests itself to a certain type of sensor and how observable it is when such a sensor is used to detect the platform. Because many military platforms use sensors in different media, it is the total of its different signatures that makes a platform more or less observable to an...

Underwater Defence of Naval Forces in Stationary Operations

During the past two decades the global security situation has seen some drastic changes. The operational scope of the Royal Netherlands Navy (RNLN) has expanded from operations on the open seas to operations both on the open seas and in littoral waters. A considerable part of the relevant operations now take place outside NATO territory....

Simulation Based Performance Assessment: Methodology and case study

During the various phases of the Defense acquisition process, and in the early design phases, many decisions must be made concerning the performance and cost of the new equipment. Often many of these decisions are made while having only a limited view of their consequences or based on subjective information. Moreover, it is known that the impact...

Signature Balancing

Signatures are an important part of the design of a ship. In an ideal situation, signatures must be as low as possible. However, due to budget constraints it is most unlikely to reach this ideal situation. The arising question is which levels of signatures are optimal given the different scenarios in which a ship operates and the incurred cost...

Operational Requirements to Air Independent Propulsion (AIP); Relating operational requirements to technical parameters for AIP

The forward areas for an LPD in littoral waters can be full of surprises. A novel concept is presented for a networked screen consisting of elements of increasing capability to provide a progressive response to the threat. This MiNeS concept substantially improves the capability of the LPD as an autonomous operational unit. The separate elements...
