Global Exponential Stability and Synchronization for Discrete-Time Inertial Neural Networks With Time Delays: A Timescale Approach

This paper considers generalized discrete-time inertial neural network (GDINN). By timescale theory, the original network is rewritten as a timescale-type inertial NN. Two different scenarios are considered. In a first scenario, several criteria guaranteeing the global exponential stability for the addressed GDINN are obtained based on the generalized matrix measure concept. In this case, Lyapunov function or functional is not necessary. In a second scenario, some inequality analytical and scaling techniques are used to achieve the global exponential stability for the considered GDINN. The obtained criteria are also applied to the global exponential synchronization of drive-response GDINNs. Several illustrative examples, including applications to the pseudorandom number generator and encrypted image transmission, are given to show the effectiveness of the theoretical results.

Factors Influencing Whistleblowing Intention Among Accountants In Malaysia

The accounting field and profession have emphasis the demand for professional accountant to build and develop ethical attitudes early in their career, even before they enter the profession which the accounting profession is closely related with whistleblowing element. To understand the factors that influences an accountant for decision to whistle blow is very crucial for both management and organisations. This study is to investigate the factors that influence an accountants’ intention to whistleblowing in Malaysia. This study narrowed the factors into several categories which are organisational factors (organisation size and job level), individual factors (locus of control) and situational factors (seriousness of wrongdoings). A total of 157 accountants had participate in an experimental design adopting four vignettes constituting four different types of wrongdoing. The result indicate that, different kind of unethical behavior reflect different level of intention to whistleblowing. The job level, locus of control and seriousness of wrongdoing were found to be significant factors that were be able to influence accountants’ intention to whistleblowing. © 2018 Published by Future Academy www.FutureAcademy. org.UK
Analisa Struktur Regional Penyebab Gempa dan Tsunami Berdasarkan Anomali Gravitasi dan Dinamika Lempeng

Peristiwa gempa bumi dan Tsunami merupakan bencana yang tidak bisa dihindari oleh masyarakat Indonesia sebagai negara yang terletak pada jalur tektonik aktif dunia. Akibat adanya pertemuan lempeng Indo-Australia pada daerah bagian Selatan Indonesia, menyebabkan kawasan ini memiliki nilai seismitas yang cukup tinggi. Salah satu kawasan yang sering terjadi peristiwa gempa dan Tsunami yaitu berada di jalur subduksi Sunda. Pada kawasan ini, terjadi beda densitas subduksi antara Pulau Jawa dan Pulau Sumatera akibat adanya perbedaan gaya kompresi pada kedua kawasan tersebut. Perbedaan densitas subduksi diketahui dari inversi data anomali gravitasi pada jalur subduksi Sunda untuk mengintepretasikan struktur regional pada area yang pernah terjadi gempa besar yang menyebabkan Tsunami. Setelah dilakukan inversi 2D terhadap data gravity pada tujuh lintasan yang searah dengan arah subduksi di jalur Sunda, dimana line 4 di daerah Jawa dan line 5 sampai 7 di daerah Sumatera. Didapatkan beda densitas pada line 1 sebesar -0.24 ~ -0.26 g/cm3; line 2 sebesar -0.25 ~ -0.5 g/cm3 ; line 3 sebesar -0.3 ~ -0.5 g/cm3 ; line 4 sebesar -0.19 ~ -0.24 g/cm3 ; line 5 sebesar -0.3 ~ -0.55 g/cm3 ; line 6 sebesar -0.1 ~ -0.26 g/cm3 dan line 7 sebesar -0.05 ~ -0.2 g/cm3. Berdasarkan beda densitas ini, diketahui bahwa daerah Jawa memiliki beda densitas lebih besar karena laju subduksi lebih tinggi dibandingkan daerah Sumatera.
Distributed Space-Time Coding for Two-Way Wireless Relay Networks

In this paper, we consider distributed space-time coding for two-way wireless relay networks, where communication between two terminals is assisted by relay nodes. Relaying protocols using two, three, and four time slots are proposed. The protocols using four time slots are the traditional amplify-and-forward (AF) and decode-and-forward (DF) protocols, which do not consider the property of the two-way traffic. A new class of relaying protocols, termed as partial decode-and-forward (PDF), is developed for the two time slots transmission, where each relay first removes part of the noise before sending the signal to the two terminals. Protocols using three time slots are proposed to compensate the fact that the two time slots protocols cannot make use of direct transmission between the two terminals. For all protocols, after processing their received signals, the relays encode the resulting signals using a distributed linear dispersion (LD) code. The proposed AF protocols are shown to achieve the diversity order of min{N,K}(1- (log log P/log P)), where N is the number of relays, P is the total power of the network, and K is the number of symbols transmitted during each time slot. When random unitary matrix is used for LD code, the proposed PDF protocols resemble random linear network coding, where the former operates on the unitary group and the latter works on the finite field. Moreover, PDF achieves the diversity order of min{N,K} but the conventional DF can only achieve the diversity order of 1. Finally, we find that two time slots protocols also have advantages over four-time-slot protocols in media access control (MAC) layer.
Adult and Peer Social Interactions During Preschool Activity: A Combination for Gender Segregation?

Evidence suggests that gender segregation begins early in life, and becomes a dominant social fact for childhood and beyond. The phenomenon of segregation starts before three years of age, and seems to accelerate through middle childhood. One of the remarkable things about this differentiation is that it seems to occur naturally during the everyday activity of children. In this paper we attempt to explore some possible root causes of this gender segregation. We observed adult/child and child/ child social interactions in a preschool classroom that might normally be considered pre‐gender segregation or early gender segregation (30‐42 months of age). The observations were conducted during two distinctly different types of preschool activities: adult/mentor dominated activities (i.e., circle time) and peer culture dominated activities (i.e., free playtime). Analysis and coding of observations suggests that adult/child social interactions were very different for interactions initiated by females and those initiated by males. These differences played out in child/child social interactions during free playtime. We hypothesize that these early activities may help in setting the trajectory for gender defined social interactions that lead to segregation.
3D Point Cloud Recognition Based on a Multi-View Convolutional Neural Network

The recognition of three-dimensional (3D) lidar (light detection and ranging) point clouds remains a significant issue in point cloud processing. Traditional point cloud recognition employs the 3D point clouds from the whole object. Nevertheless, the lidar data is a collection of two-and-a-half-dimensional (2.5D) point clouds (each 2.5D point cloud comes from a single view) obtained by scanning the object within a certain field angle by lidar. To deal with this problem, we initially propose a novel representation which expresses 3D point clouds using 2.5D point clouds from multiple views and then we generate multi-view 2.5D point cloud data based on the Point Cloud Library (PCL). Subsequently, we design an effective recognition model based on a multi-view convolutional neural network. The model directly acts on the raw 2.5D point clouds from all views and learns to get a global feature descriptor by fusing the features from all views by the view fusion network. It has been proved that our approach can achieve an excellent recognition performance without any requirement for three-dimensional reconstruction and the preprocessing of point clouds. In conclusion, this paper can effectively solve the recognition problem of lidar point clouds and provide vital practical value.
EL TAG COMO CELDA DE VIGILANCIA. Una visión crítica de los metadatos y sistemas de reconocimiento facial a través de las prácticas artísticas

Nowadays, the expansion of social networks has made possible the emergence of a new, decentralized and diffused surveillance model. Web 2.0 and smartphone devices allow the circulation of private information available to users and public-private companies that are part of the new network economy. The daily use of applications with gps locator allows the storage of all kinds of activities and to carrying out the reconstruction of all our actions, desires and affections. In a context of hyper-exposure, of the hyper-connected 24/7 society, it is considered to be as a new model of more diffused surveillance, but maintaining the same effect of the Panopticon. This has an impact on user psychology creating a disciplinary power in the face of uncertainty of being under constant surveillance. The concept of Panopticon's isolation and surveillance cell is reflected today, not only in each personalized account in social networks, but in all the information that is recorded in the Google history associated with a personal email account, Paypal accounts and countless apps that register heart rate, fingerprints, sleep curves and blood sugar. These applications allow the total registration of all physical, biological and affective actions and movements. From Foucault’s perspective, social media is more than a vehicle for the exchange of information, it is a vehicle for the formation of identity and its control.
EVALUATION OF THE FACTORS AFFECTING THE GROWTH INTENSITY OF CHAROLAIS CALVES

The aim of study was to evaluate the growth indicators in total of 1,986 purebred Charolais calves in relation to the sex, year of birth, birth season of the calves and also dam ́s parity. At the same time, the object of work was to evaluate cows’ longevity. We found higher values of live weight in bulls (P>0.05), the occurrence of twins showed lower birth weight (P<0.001) and weaning weight (P>0.05). The spring season of calving had an influence on lighter offspring in birth weight (P<0.001) as well as in pre-weaning period (P<0.001); the heaviest calves were born in the winter calving season. Calves born to primiparous cows were markedly lighter at birth (P>0.05), at the age of 120 days (P>0.05), and also at the weaning (P<0.05) than those born to older cows. The linear model characterized by the coefficient of determination for all fixed effects was R = 0.714862% for birth weight (BLW), R = 0.375164% for weight at 120 days (LW120) and R = 0.473550% for weaning weight (LW210). On the basis of the results, we can observe the increased growth performance of calves over the years, pointing to the adaptation of Charolais to conditions in Slovakia.
Expanded teased nerve fibre pathological conditions in disease association

Objective To describe an expanded teased nerve fibre classification in disease association. Methods We reviewed four newly proposed teased nerve fibre types (Types J–M): Type J, rope-like fibres; K, fibril-like clumps of osmium positivity; L, cellular debris along and within nerve fibres; M, circular axonal inclusions surrounded by thin myelin. Different clinical pathological entities were studied for these fibre types including chronic inflammatory demyelinating polyradiculoneuropathy (CIDP: N=20); amyloid polyneuropathy (N=20); intraneural B-cell lymphoma (N=20) or adult-onset polyglucosan body disease (APBD: N=6) in comparison with 112 disease controls. Student’s t-test was used to test significance of association between the identified fibre types and the specific clinical diagnosis. Results Each fibre type significantly associated (p<0.001) with particular disease categories: Type J, 60% of CIDP cases; Type K, 75% of amyloid cases; Type L, 75% of intraneural lymphoma cases; Type M, 100% of APBD cases. Rarely were these fibres found in the other disease control cases ≤3% of cases. In three cases, the teased fibre findings were so striking additional paraffin nerve preparations were made to make the pathological diagnosis when initial paraffin sections were non-diagnostic. Conclusions Teased nerve fibre Types J–M associate with commonly seen pathological diagnosis and are helpful in the consideration of specific neuropathy diagnoses.
Importance du dépistage et du traitement précoces des psychoses

Le diagnostic différentiel des phases psychotiques précoces représente l’un des défis majeurs de la psychiatrie. Les consultations spécialisées disposent de l’expertise nécessaire pour faire la distinction entre les réelles situations à risque et les situations non à risque, mais également entre les troubles psychotiques aigus transitoires et les troubles psychotiques persistants, ce qui est tout aussi déterminant pour le choix de la méthode de traitement que pour éviter une stigmatisation inutile, qui doit être empêchée par tous les moyens. La collaboration entre les différentes consultations spécialisées permet en outre qu’un nombre suffisamment élevé de patients puisse être évalué scientifiquement et que les interprétations aient une pertinence suffisante.

This thesis presentation will discuss stability assessments of orbits around asteroids, with in particular the asteroid Eros. The gravity field of an asteroid can be estimated using different techniques. For the thesis work presented the Polyhedron, Spherical Harmonic Expansion and Triaxial Ellipsoid methods are implemented on the Eros case. The differences in performance of the different gravity field modelling techniques will be discussed. The irregularity of the gravity field of Eros will have consequences on the orbital stability of satellites orbiting Eros, the influence of this irregularity will be estimated. Furthermore, the influence of the Solar Radiation Pressure and Third-body Perturbing forces on the stability of orbits around Eros will be determined. With the help of the Monte Carlo method and the Particle Swarm Optimization method a search is performed to find stable orbits within the vicinity of Eros.
Microbiological assessment of cutleries

Microbial contamination of food is a major public health problem since it affects millions of people worldwide. Unproved hygienic practices within the food processing environment can cause the contamination with pathogenic particles, turning food into a risk for the safety of the consumers. For the assessment of the hygienic condition related to food handling is essential to know the sanitary conditions of the establishment since that can reduce the risks of food contamination. That food contamination can cause severe problem to the consumer’s health. Microbial attachment and biofilm formation to solid surface of crockery and cutlery provide some protection of the cell against physical removal of the cell by washing and cleaning crockery.1 These cells seem to have greater resistance against sanitizers and heat, thus spoilage and pathogenic microorganisms attached to food surface. Zattola2 reported that microbial cells attached to equipment surfaces especially those that come in contact with the food, may not be easily killed by chemical sanitizers or heat designed to be effective against unattached microbial cells; and thus they can contaminate food. The washing of hands, utensils, and dishes is often done in buckets or bowls in such disinfection are carried out.3 It also has been reported that several species and strains of Pseudomonas were found to attach to stainless steel surface within 30 minutes of contact. Listeria monocytogenes was found to attach to stainless steel surface, glass and rubber surface within 20 minutes of contact and some of the microorganisms found are Staphylococcus species, Escherichia coli, Bacillus species and Pseudomonas species.2
