Coalition operations are increasingly effects-based, which means they apply force only as necessary to achieve political and psychological effects. Capture the Flag is a wargaming environment that includes intelligent, autonomous adversaries. Our planner previously focused on two goals: occupying objectives and attrition. But attrition is a means to the defeat of one’s enemies, not an end in it...

Differentiated Service Model (DiffServ) is currently a popular research topic as a low-cost method to bring QoS to today’s Internet backbone network. Simulation is the best way to study DiffServ before deploying it to the real Internet. In this paper, we introduce the techniques and methodologies that we used to design and implement DiffServ-enabled (DS-enabled) routers by using OPNET. We have ...

This paper examines the problem of video transport over ATM networks using knowledge of both video system design and broadband networks. We find that the following trends hold for all sequences examined. First, increasing the delay in the video system decreases the necessary peak rate and significantly increases the number of calls that can be carried by the network. Second, as an operational t...

In this paper, usage parameter control (UPC) is presented to ensure that each source conforms to its negotiated parameters in ATM networks. To meet the requirements for the policing function, a fuzzy logic-based system is proposed to deal with the congestion control and policing problem in ATM networks. There are four types of different mechanisms, Jump Window (JW), Exponentially Weighted Movin...

Despite some studies on bearing capacity have been studied, the detail responses of the suction bucket foundations under dynamic loads have remained unknown [3]. The dynamic load condition is significant when suction buckets are used as the foundation of an offshore structure. Wave load, ice-induced or wind-induced load cause the foundation to be subjected to cyclic loads [4]. The dynamic load ...

Color histograms are widely used for content-based image retrieval. Their advantages are eeciency, and insensitivity to small changes in camera viewpoint. However, a histogram is a coarse characterization of an image, and so images with very diierent appearances can have similar histograms. We describe a technique for comparing images called histogram re-nement, which imposes additional constra...

Locality sensitive hashing (LSH) has been used extensively as a basis for many data retrieval applications. However, previous approaches, such as random projection and multi-probe hashing, may exhibit high query complexity of up to Θ(n) when the underlying data distribution is highly skewed. This is due to the imbalance in the number of data stored per each bucket, which leads to slow query tim...

Workers in a bucket brigade production system perform unproductive travel when they walk to get more work from their colleagues. We introduce a new design of bucket brigades to reduce unproductive travel. Under the new design, each worker works on one side of an aisle when he proceeds in one direction and works on the other side when he proceeds in the reverse direction. We propose simple rules...

A method is developed to quantify systematic errors in two types of sea surface temperature (SST) observations: bucket and engine-intake measurements. A simple linear model is proposed where the SST measured using a bucket is cooled or warmed by a fraction of the air–sea temperature difference and the SST measured using an engine intake has a constant bias. The model is applied to collocated ni...

We present a deterministic summary structure over update streams that enables deterministic and the first space-optimal algorithms for a variety of problems, including, estimating frequencies, finding approximate frequent items, finding approximate quantiles, finding hierarchical heavy hitters, approximately optimal B-bucket histograms, estimating inner product sizes, etc..
