Introduction of wireless vehicular communications enables a variety of new Intelligent Transportation System (ITS) use-cases [1, 2], allowing the services to cooperate between vehicles and infrastructure. Furthermore modern vehicles feature an increasing number of driving automation functions. This paper identifies requirements for cooperative and automated ITS, with a special emphasis on the setup...
The threat of voice spam, commonly known as Spam over Internet Telephony (SPIT) is a real and contemporary problem. We present two approaches based on the anomaly detection of the distributions of selected call features (i.e., day and time of calling, call durations etc.) to detect and prevent SPITting over the Internet. The first approach uses Mahalanobis Distance as a summarization tool and it is...
This paper presents a prototype biometric system that performs real time human identification using the ECG signal. Cardiac signals have been lately suggested for biometric deployment, since they carry subject specific information and at the same time allow for inherent liveness detection. The HeartID is the first system to continuously authenticate individuals who are conveniently wearing a portable,...
This paper discusses ECG biometric recognition in a distributed system, such as smart cards. In a setting where every card is equipped with an ECG sensor to record heart beats from the fingers, and to subsequently perform identity verification, the interest is in protecting the card holder from a set of unknown/unseen biometric traits. Prior works have examined ECG biometrics in settings where a particular...
Documents often contain inherently many concepts reflecting specific and generic aspects. To automatically generate a short summary text of documents on similar topics, it is imperative that we discover general aspects in documents because summaries usually contain general rather than specific concepts. This paper presents a semi-supervised extractive summarization model based upon latent concept...
This paper discusses merits, advantages, and disadvantages of integrating breaker failure (BF) protection with zone protection relays (ZPRs). In this context, the paper considers cost savings, security and dependability, simplicity, the danger of human errors when testing bus configurations, overall relaying philosophy, and reliability of applied protection devices. Several ways of integrating BF...
Vehicle Performance testing for equipment selection programs affect economic and social benefits is proposed based on normative, economic, technical, service, energy saving and environmental protection, human relations elements of the testing equipment selection evaluation criteria system. Extension theory based on equipment selection decision-making feature set, the use of expert experience to establish...
Complex SQL queries are widely used today, but it is rather difficult to check if a complex query has been written correctly. Formal verification based on comparing a specification with an implementation is not applicable, since SQL queries are essentially a specification without any implementation. Queries are usually checked by running them on sample datasets and checking that the correct result...
We review progress towards developing a new human-computer interface that uses only a single sEMG sensor to achieve complex control of external devices. The interface relies on an underlying neuromuscular result, in which we showed that the human neuromuscular system can simultaneously manipulate partial power in two separate frequency bands of a sEMG power spectrum at a single muscle site. Subjects...
We explain the implementation of series of prototypes to assist the teaching of handwriting skills for children with dyspraxia, using a computer animation technique called Rotoscopy. We discuss usability testing issues which include parameters and scales used to evaluate the prototype systems.
The complex decision making experimental platform (CODEM) is intended as a shareable research tool to stimulate multidisciplinary research on complex dynamic situation management and as an environment for training and testing cognitive readiness. The experimenter can set general parameters, configure the interface, specify the model, insert events and define the resources and capabilities of each...
Any changes for maintenance or evolution purposes may break existing working features, or may violate the requirements established in the previous software releases. Regression testing is essential to avoid these problems, but it may be ended up with executing many time-consuming test cases. This paper tries to address prioritizing requirements-based regression test cases. To this end, system-level...
This paper presents the combination of electroencephalogram (EEG) power spectrum ratio and Spectral Centroids techniques to extract unique features for human stress from EEG signals. The combination of these techniques was able to improve the k-NN (k-Nearest Neighbor) classifier accuracy to detect and classify human stress from two cognitive states, Close-eye (CE) and Open-eye (OE). The EEG power...
Landing humans on Mars is perhaps the largest Entry, Descent and Landing challenge for this (or any) generation of NASA engineers. Essentially all current Mars EDL technology is based on development efforts in support of the Viking program in the 1960's and 1970's. Since that time, these key technologies have been tweaked and some additions have been added in order to extend the landed mass and altitude...
This paper describes an analysis of body radiation frequency for the purpose of gender classification. The human radiation frequency is experimentally studied from 33 healthy human subjects of 17 males and 16 females. KNN classifier is employed for gender classification. The number of training to testing ratio was evaluated at 50 to 50, 60 to 40 and 70 to 30, to determine best classification accuracy...
We propose a novel approach for enhancing precision in a leading video analytics system that detects cashier fraud in grocery stores for loss prevention. While intelligent video analytics has recently become a promising means of loss prevention for retailers, most of the real-world systems suffer from a large number of false alarms, resulting in a significant waste of human labor during manual verification...
In this paper, we propose a game-based public testing mechanism called GATE. The purpose of GATE is to make use of the rich human resource on the Internet to help increase effectiveness in software testing and improve test adequacy. GATE facilitates public testing in three main steps: 1) decompose the test criterion satisfaction problem into many smaller sub-model satisfaction problems; 2) construct...
With the advent of Web 2.0 applications and new browsers, the cross-browser compatibility issue is becoming increasingly important. Although the problem is widely recognized among web developers, no systematic approach to tackle it exists today. None of the current tools, which provide screenshots or emulation environments, specifies any notion of cross-browser compatibility, much less check it automatically...
A novel algorithm for view-invariant human action recognition is presented. This approach is based on Two-Dimensional Principal Component Analysis (2DPCA) applied directly on the Motion Energy Image (MEI) or the Motion History Image (MHI) in both the spatial domain and the transform domain. This method reduces the computational complexity by a factor of at least 66, achieving the highest recognition...
As a supporting tool for visually impaired persons, digital talking book contents, that read beading handicraft design diagram, was developed. Beading handicraft is one of popular recreational activity by visually impaired persons in community circles. The developed software recognizes symbols on design diagrams. From the output of the recognizer, the subsequent program makes sentences to be read...
