Increasingly people form opinions based on information they consume on online social media. As a result, it is crucial to understand what type of content attracts people's attention on social media and drive discussions. In this paper we focus on online discussions. Can we predict which comments and what content gets the highest attention in an online discussion? How does this content differ from...
Developing high quality software is a major industry concern, since programs that "just work" may not be suitable to contemporary technological challenges. Agile practices, such as Test-First development (TFD), may help in this direction. However, in our experience this technique is introduced late (if ever), when programmers' habits are already set and difficult to change. Early exposure...
The practitioner interested in reducing software verification effort may found herself lost in the many alternative definitions of Graphical User Interface (GUI) testing that exist and their relation to the notion of system testing. One result of these many definitions is that one may end up testing the same parts of the Software Under Test (SUT), specifically the application logic, twice. To clarify...
The article focuses on experimental measurement of multi-carrier narrowband Power Line Communication. The aim of experimental measurements was comparison of multi-carrier narrowband Power Line Communication from the view-point of possible communication distance, available data rate and impact of noise. The specifications G3-PLC and PRIME are considered. The field test results and data rate measurements...
Low resolution satellite products are often validated by point-scale in-situ soil moisture measurements from TDR/FDR devices, where the scale mismatch limits the quality of validation efforts in heterogeneous regions. In Cosmic Ray Neutron Probes (CRNP) provide area-average soil moisture within a 150–250 m radius footprint, so that they are able to fill the scale gap between both systems. In this...
Understanding temporal expressions is the important foundation of many NLP tasks. However, the varied representations of temporal expressions is difficulty in analysis and understanding. To parsing expressions, an effective classification method of temporal expressions is significant. A temporal expression may belong to one or more classes, but the classification usually requires manual annotation...
Wireless Mesh Networks (WMNs) employ hybrid distributed mobile networks with instant deployment and capabilities Such as: self_healing, self_organization and self_configuration. These abilities make WMNs a likely technology for incident communication. An Incident Area Network (IAN) requires a reliable and efficient routing path in an environment, where infrastructure-based communications have been...
The evaluation of recommender system is often biased towards accuracy, which is hard to balance all participants' interests. In this paper, a novel recommendation strategy using expanded neighbor collaborative filtering (ECF) is presented. Different from the standard collaborative filtering (CF), this recommendation strategy takes into account the second-order neighbors, which are expected to contribute...
Field Programmable Gate Array (FPGA) system is widely used in deep learning application and cloud system for acceleration. Quality and reliability of IP block is essential to the successful development of today's complex hardware acceleration design. In this paper, we discuss the important issues of quality and reliability of digital soft IP, and propose a qualification measurement system that can...
Learning vector quantization (LVQ) enjoys a great popularity as efficient and intuitive classification scheme, accompanied by a strong mathematical substantiation of its learning dynamics and generalization ability. However, popular deterministic LVQ variants do not allow an immediate probabilistic interpretation of its output and an according reject option in case of insecure classifications. In...
Code portability is a desirable non-functional requirement. The most established metric evaluating it consists of counting the number of instructions that use platform specific APIs. Generally, instructions using APIs are preceded or followed by related code that e.g. prepares some input for a call or analyses the return value. This paper proposes a taint analysis approach to identify code portions...
Two channels are said to be equivalent if they are degraded from each other. The space of equivalent channels with input alphabet X and output alphabet Y can be naturally endowed with the quotient of the Euclidean topology by the equivalence relation. We show that this topology is compact, path-connected and metrizable. A topology on the space of equivalent channels with fixed input alphabet X and...
We extend the self-organizing mapping algorithm to the problem of visualizing data on Grassmann manifolds. In this setting, a collection of k points in n-dimensions is represented by a k-dimensional subspace, e.g., via the singular value or QR-decompositions. Data assembled in this way is challenging to visualize given abstract points on the Grassmannian do not reside in Euclidean space. The extension...
Middleware is being extensively used in Internet of Things (IoT) deployments and is available in a variety of flavors — from general-purpose community-driven middleware and telco-developed Machine-to-Machine (M2M) middleware to middleware targeting specific deployments. Despite this extensive use and diversity, little is known about the benefits, disadvantages, and performance of each middleware platform...
This paper describes various real-world design applications from the communications & measurement industry that have been solved by Differential Evolution (DE). The commonalities of these applications are discussed, and the characteristics are identified that gave rise to a DE-based design. It is further laid out which requirements need to be fulfilled to make DE more widespread and which expectations...
Due to different technical-economical reasons, power systems tend to interconnect each other. The resulting system after the interconnection could be reorganized into two or more control areas in terms of secondary frequency control; if this is the case, the resulting control areas may require new automatic generation control (AGC) parameters to maintain compliance with performance standards. In addition,...
In this paper, we study the correlation between passwords across different datasets which quantitatively explains the success of existing training-based password cracking techniques. We also study the correlation between a user's password and his/her social profile. This enabled us to develop the first social profile-aware password strength meter, namely SociaLShield. Our quantification techniques...
We present a new method for scheduling independent tasks on a parallel machine composed of identical processors. This problem has been studied extensively for a long time with many variants. We are interested here in designing a generic algorithm in the on-line non-preemptive setting whose performance is good for various objectives. The basic idea of this algorithm is to detect some problematic tasks...
In this work a preliminary study is proposed to assess the validity of an automatic and low cost measurement method for Functional ReachTest (FRT) implementation. To this aim FRT was performed on 10 trials of 4 healthy men and results from the system under validation are compared with the corresponding data from a calibrated stereo-photogrammetric system: the percentage variation between them is lower...
This paper presents a rotational speed measurement system based on a low-cost imaging device with a simple marker on the rotor. Structural similarity and two-dimensional correlation algorithms are deployed to process the images. The measurement principle, structure design and performance assessment of the proposed system are presented and discussed. The effects of different markers, image processing...
