We analyze the symmetry properties of these PO and their relation with the PO set appearing in Higgs decays. We discuss in detail the kinematical studies necessary to extract the production PO from data, and present a first estimate of the LHC sensitivity on these observables in the high-luminosity phase. The impact of QCD corrections and the kinematical studies necessary to test the validity of the momentum expansion at the basis of the PO decomposition are also discussed.
Summary Denial of service (DoS) attack is an attempt of the attacker to disable victim's machine by depleting network or computing resources. If this attack is performed with more than one machine, it is called distributed denial of service (DDoS) attack. Covert channels are those channels which are used for information transmission even though they are neither designed nor intended to transfer information at all. In this article, we investigated the possibility of using of DDoS attack for purposes of hiding data or concealing the existing covert channel. In addition, in this paper we analyzed the possibility of detection of such covert communication with the well-known statistical method. Also, we proposed the coordination mechanisms of the attack which may be used. A lot of research has been done in order to describe and prevent DDoS attacks, yet research on steganography on this field is still scarce.
The packaging materials industry has already recognized the importance of Total Productive Maintenance as a system of proactive techniques for improving equipment reliability. Bearing faults, which often occur gradually, represent one of the foremost causes of failures in the industry. Therefore, detection of their faults in an early stage is quite important to assure reliable and efficient operation. We present a new automated technique for early fault detection and diagnosis in rolling-element bearings based on vibration signal analysis. Following the wavelet decomposition of vibration signals into a few sub-bands of interest, the standard deviation of obtained wavelet coefficients is extracted as a representative feature. Then, the feature space dimension is optimally reduced to two using scatter matrices. In the reduced two-dimensional feature space the fault detection and diagnosis is carried out by quadratic classifiers. Accuracy of the technique has been tested on four classes of the recorded vibrations signals, i.e., normal, with the fault of inner race, outer race, and ball operation. The overall accuracy of 98.9% has been achieved. The new technique can be used to support maintenance decision-making processes and, thus, to increase reliability and efficiency in the industry by preventing unexpected faulty operation of bearings.
The elections to the Swiss Federal Council in December 2015 re-established a system of party-centred concordance, cherished in consociational theory, consisting of two representatives of the Swiss People's Party, two Radicals, two Social Democrats and one Christian Democrat. At the same time, the government has rarely been as unbalanced in terms of the representation of Switzerland's languages and regions. The article analyses the concept of concordance with regard to both aspects of governmental inclusiveness. It also highlights the crucial role of electoral rules used in governmental elections. It argues that they resemble the Alternative Vote, a majoritarian electoral system that has been criticized in consociational theory but prescribed by the rival, centripetalist approach to power sharing.
Abstract Background: Companies can improve their business performance, increase revenues and reduce costs by enhancing their information technology (IT) capability. On the other side, there is an increasing importance of human resource management (HRM) practices related to IT utilization, which are important for the business performance of a company in the rapidly changing knowledge-based economy. Objectives: The objective of this paper is to analyze the relations among IT capability, HRM capability and the firm’s performance outcomes. Methods/Approach: The paper uses survey data and Structural Equation Modeling to analyze the relationships among IT capability, HRM capability and firms’ performance. Results: This paper reveals that IT capability to some extent determines firms’ business performance but it plays more important role in enhancing HRM capability. In addition, HRM capability significantly impacts business performance. Conclusions: The findings indicate that managers should not focus on allocating resources only for IT investments. In order to achieve better business performances, these technologies need to be used to support all business processes including HRM activities.
Abstract The aim of this study is to examine the technical quality of root canal fillings in an adult population in the Republic of Srpska, Bosnia and Herzegovina, who were treated in public dental institutions and private dental clinics. Radiographs of faculty patients, aged 25-60 years old, who came for the first time were examined for the technical quality of root canal fillings. Patients with endodonticallytreated teeth were invited for an interview to reveal the providers of the endodontic treatment. The percentages of teeth with adequate length (p<0.01) and taper (p<0.01) in institutions of public health cases were significantly greater than those in private clinic cases. In addition, the frequency of teeth with adequate root canal fillings in patients treated in public dental institutions was significantly greater than those treated in private dental clinics (p<0.01). A significantly higher percentage of adequate canal fillings is present in teeth where endodontic treatment was performed in public dental institutions compared to private dental clinics. This result indicates the need to improve the quality of endodontic treatment through more intensive training for dentists in private practice.
