A wearable guidance system is designed to provide context-dependent guidance messages to blind people while they traverse local pathways. The system is composed of three parts: moving scene analysis, walking context estimation and audio message delivery. The combination of a downward-pointing laser scanner and a camera is used to solve the challenging problem of moving scene analysis. By integr...

There is need for an energy storage device capable of transferring high power in transient situations aboard naval vessels. Currently, batteries are used to accomplish this task, but previous research has shown that when utilized at high power rates, these devices deteriorate over time causing a loss in lifespan. It has been shown that a hybrid energy storage configuration is capable of meeting...

In this paper we aim to give an introduction to fuzzy logic using the language Haskell to implement our solutions. We shall see how the high-level, declarative nature of a functional language allows us to implement easily and eeciently solutions to problems using fuzzy logic and, in particular, how the presence of functions as rst-class values allows us to model the key concept of the fuzzy sub...

The automation of complex industrial batch processes is a difficult problem due to the extremely nonlinear and variable system behavior or the conflicting goals within the different process phases. The introduction of a single multipleinput multiple-output controller (e.g. fuzzy logic (FL) controller) is not useful because of the rather high design effort and the low transparency of its complex...

this paper presents a new damping controller design based on fuzzy wavelet neural network (fwnn) to damp the multi-machine power system low frequency oscillations. the error between the desired system output and the output of control object is directly utilized to tune the network parameters. the orthogonal least square (ols) algorithm is used to purify the wavelets for each rule and determine ...

Fuzzy logic has proved in this paper, a medical fuzzy data is introduced in order to help users in providing accurate information when there is inaccuracy. Inaccuracy in data represents imprecise or vague values (like the words use in human conversation) or uncertainty in using the available information required for decision making handle the uncertainty of critical risk for human health. In th...

Feature subset selection supports the classification task by reducing the search space as well as by removing irrelevant and random features, which might compromise the resulting classification model. Decision trees perform an embedded feature selection as they select only the relevant features for the splitting of the datasets during the induction process. FUZZYDT is a fuzzy decision tree whic...

Infrared point-target detection is one of the key technologies in infrared guidance systems. Due to long observation distance, point target often submerged background clutter and large noise process atmospheric transmission scattering, signal-to-noise ratio low. On other hand, image appears form fuzzy points, so that has no obvious features texture information. Therefore, scholars have proposed...

The adoption and diffusion of RFID in logistics falls short behind the optimistic expectations shaped years ago. The complexity of large-scale RFID rollout projects is a barrier for widespread adoption and diffusion of RFID. Current RFID specific project management frameworks address the implementation of isolated RFID projects but provide very limited guidance on how to manage largescale RFID ...

Currently, BPM is considered as the suitable framework for today’s process-centric trends and BPM may result in considerable rewards for companies adopting it. For successful BPM initiative, the selection of suitable processes for BPM is very important. However, it is difficult to evaluate systematically and reasonably business processes for enterprises that plan to introduce BPM. This paper de...
