Deep Learning Framework for Density Estimation of Crowd Videos

Estimation crowd density from surveillance video is a significant research filed in the area of computer vision. Crowd density is one of the critical crowd monitoring parameters which can represent the space that is possessed by the crowd in the scene under surveillance. The space available for crowd gathering in a particular area may be limited, and the authorities need to restrict the crowd in that area within that predefined limit. If the density of the crowd exceeds that predefined limit, some congestion may occur in that scene. To avoid this congestion, we can incorporate the density parameter to the existing surveillance system to make the surveillance system more intelligent. In this paper, we propose a new crowd density estimation strategy using deep learning frameworks like convolution neural network and long short-term memory network. The experiment is tested with CUHK Crowd dataset, and the result is compared with existing crowd density estimation methods available in the literature.
Study on Community Discovery Algorithm from the Perspection of Label Influence Propagation

In order to better discover the overlapping communities, this paper proposes an overlapping community detection method (INFELPA) based on the influence of the label and the spread of the edge tags. We use the influence of the node to initialize the label on the edge and sort the edge's influence to avoid these random factors during the edge label updating process. In order to retain multiple communities we retain multiple labels on the edges and restore the completed edge tag to the node. The experimental results show that this algorithm has certain competitive advantages
A Siamese Adversarial Anonymizer for Data Minimization in Biometric Applications

A wealth of sensors measure our day to day activities. Sharing these biometric data with cloud-enabled applications provides users with useful insights about their health status. However, due to their high re-identification potential, granting medical and fitness applications access to sensors data raises serious privacy concerns.In this work, we aim to find a data representation that sup-presses identity while retaining utility, i.e. data minimization. To this end, we define a component that is plugged into a machine learning pipeline and trained following a min-max adversarial optimization strategy. By using our component during training, we limit the need to rely on third parties and, therefore, reduce the risks of leakages and unintended processing. We evaluate privacy vs. utility trade-off on a real-world sharing scenario involving motion data, i.e. accelerometer and gyroscope measurements. Privacy is estimated by analyzing if an honest-but-curious attacker can effectively link two traces to the same user. In our experiments, we observe a decrease in test verification accuracy, i.e. the identifiability of the users, from 85% to 57%. This leaves an attacker with a representation that he can match only slightly better compared to a random guess. On top of that, the privatized gait representation is accompanied by an increase in performance w.r. t. the main tasks.

Sensory Feedback Device for Myoelectric Prosthetic Hand

In this work, a sensory feedback device for myoelectric prosthetic hand was developed to enhance the quality of life (QOL) of myoelectric prosthetic hand users. Two types of sensory feedback, namely, force sense feedback and temperature sense feedback, were proposed. As for the feedback device of force sense, the device is mounted on the user’s upper arm and provides hardness of the object onto the upper arm by winding a belt using a motor. On the other hand, as for the feedback device of temperature sense, the device is mounted on the user’s upper arm and presents temperature of the object onto the upper arm using a Peltier element. Finally, two-sensory feedback devices were united, and a two-sensory feedback device was built.
Poems of the Revolution

Ethnopoetry statement: I have taken to heart the observation by Bjørn Thomassen (2012) in his essay ‘‘Notes Towards an Anthropology of Political Revolutions’’ that ‘‘the study of political revolutions ought to figure more prominently in both ethnography and anthropological theory’’ (p. 701). My earlier ethnographic work includes an embedded study of small-town life (Raisor, 2013) and American sports (Raisor, 2014), both deeply rooted in my own experience. For my current project, I have not set up a field study of revolutionary events, so my recent poems are historical in nature. I have drawn from wide-ranging texts and used one of poetry’s favorite devices—the persona—to enter lives, which have, in fact, experienced a revolution. Thus, my characters, such as Mrs. Pankhurst, Victor Serge, Nathan Hale, and numerous faceless participants, expose the components of the revolutionary mind—its bitterness, failures, aspirations, its death-defying self-centeredness, and what James Scott (1990) calls its ‘‘hidden scripts. ’’ Today, journalists are often on the frontlines of revolutionary activity. In the three poems I am submitting, I have placed my reporters in a ‘‘field study’’ of their own. In the midst of micro and macro events, they often find that both are tragic and understandable. Form, content, and narrative are inextricably linked in these poems. My narrators are forced to go beyond simply reporting; they are moved to comprehend the contradictions, cross-purposes, and downright absurdities that accompany the pursuit of change. What they often discover, on the one hand, is the ambivalence of the revolutionary experience, and, on the other, the enduring persistence of the ‘‘I’’ to remain the enduring symbol of resistance. I think that by listening to the voices in these three poems and being drawn into their conditions, we are better able to understand and feel (that’s what poetry does) both the intractability and dangers of the revolutionary spirit.
An Optimal Radius of Influence Domain in Element-Free Galerkin Method

The domain of influence (doi) plays a very important role in the Element Free Galerkin (EFGM) method. It contributes to the calculation of the weight function and so influences the accuracy of the approximation. The radius of the (doi) determines the number of nodes contained in the support. The compromise is that the radius must not be large to not lose the local aspect of the moving least square method (MLS) used in (EFGM) and not small to have enough node so a regular moment matrix. This paper compares several theories for calculating the radius of (doi).
The Effect of the Carrier Drift Velocity Saturation in High-Power Semiconductor Lasers at Ultrahigh Drive Currents

Experimental light–current characteristics of high-power semiconductor lasers operating at ultrahigh drive currents have been studied in terms of numerical models taking into account the effect of the carrier drift velocity saturation. It was shown that the simplest diffusion–drift (DD) model underestimates the optical loss at high drive currents, which leads to overestimation of the peak optical power when compared with the experimental results. The inclusion of the carrier drift velocity saturation effect into the DD model results in that a strong-electric-field domain is formed at the interface with the active region on the side of the p-emitter already at low drive currents. The amplitude of this field substantially grows as the current increases further, which restricts application of this model to description of high-power semiconductor lasers at high drive currents. With the nonlocal energy-balance model used to describe the carrier transport in the laser heterostructure, it becomes possible to take into account the effect of carrier heating by the electric field. As a result of the carrier heating, the drift velocity decreases and the concentration of excess carriers in the waveguide layer grows, compared with the simplest DD model. The inclusion of the additional internal optical loss mechanism obtained in the energy-balance model provided a satisfactory coincidence of the calculated light–current characteristics with the experimental dependences.
Bronchoscopic Myths and Legends: Elevated Intracranial Pressure

In an age where medical practice and decision making are based upon evidence-based medicine, medical training still has an “apprenticeship” portion. Different medical and procedural approaches are learned based partly on individual training locations and trainers’ experience due to few randomized studies. In an age when performing studies is not only limited by patient and diagnostic availability but also by funding and patient regulations, studying established methods of treating people is not always at the forefront of new research.Bronchoscopy is not any different. We set out to review available literature on several “rules” passed down to trainers and fellows. We review these myths and legends and their strength or lack thereof in presently available literature.
Detecting Establishment Shots Using Camera Motion

Abstract The film grammar used in movie-making industry dictates that most story units start with an establishment shot, which has the intention of bringing the audience to a new environment. Identification of establishment shots can aid in scene segmentation and video summarization. This paper describes a retrieval system that is capable of detecting establishment shots using camera motion features. Experimental results on several hours of real video data show the potential of our approach.
A 2.4-GHz Area-Efficient and Fast-Locking Subharmonically Injection-Locked Type-I PLL

A 2.4-GHz area-efficient and fast-locking subharmonically injection-locked type-I phase-locked loop (SIL-TPLL) is presented. A timing-adjusted phase detector (TPD) is proposed to calibrate the injection timing. This TPD also reduces the settling time of the SIL-TPLL. The loop capacitance of the type-I PLL is tiny to save the area. This SIL-TPLL is fabricated in 45-nm CMOS technology. Its active area is 0.013 mm2. The power consumption is 5.6 mW at 2.4 GHz for a supply of 0.87 V. The integrated jitter of the SIL-TPLL over 1 kHz to 40 MHz is 0.91 ps.
Effective Case Study Methodologies in the Management of IT Courses

Many AACSB accredited schools require undergraduates MIS majors to take a course in the managemen t of information technology. Over half of these schools utilize case studies in the teaching of this course. We believe that case studies are an important vehicle for teaching crucial IT management issues, particularly in providin g students with a real-world example of organizational issues. We believe that case studies are best taught in an active, collaborative environm ent. Based upon our understanding of collaborative learning and collaborative teaching, we propose a procedure for enhancing the effectiveness of this active learning methodology. COLLABORATIVE LEARNING Collaborative learning is defined as a learning process emphasizing group or cooper ative efforts a mong faculty and students, stressing active participation and interaction on the part of both students and instructors (Brufee, 1984). Collaborative learning has long been stressed as an effective teaching methodology by theorists (Vygotsky, 1978 ). A review of the literature of peer/collaborative learning can be found in McK eachie (1999). The importance of collaborative learning extends to the business environment, particularly in the use of teams to accomplish business tasks. The effectiveness of using teams to accomplish information systems tasks in the business environm ent is well recognized (El-Shinnawy and Vinze, 1998; Janz, 1999). Surveys of employers indicate that teamwork skills are among the most important wh en evaluating IS graduates for entry-level positions. Employers have rated teamwork skills as more important than systems analysis and design, database, or programming skills (Van Slyke, Kittner and Chen ey, 199 8). Collaborative learning is recognized as an effective teaching methodology in MIS programs in the United States. Through collaborative learning, students lea rn to take advantage of each team mem ber’s expertise and to experience first-hand the problems of coordinating a team effort (Goyal, 1995/1996). Studies have shown that collaborative learning leads to a higher degree of satisfaction with the learning process, to a greater motivation to learn, and to better performance (Flynn, 1992) . Aram and Noble (1999) argue that the traditional lecture approach does not ad equately p repare stud ents to understand and cope with the levels of ambiguity and uncertainty they will inevitably face when assuming entry level positions. Collaborative learning can be utilized in a number of class settings, and it is particularly appropria te for system development projects . Collaborative learning can also be effectively used for research projects and simulations. However, it is our intention to focus on how teac hers can utili ze techniques of collaborativ e learning in the teaching of case studies in the Management of IT course.
Antecedents of continued use and extended use of enterprise systems

ABSTRACT This study examines the antecedents of continued use and extended use of Enterprise Systems (ES). Data were collected from 345 business executives through a self-administered questionnaire survey and are analysed using structural equation modelling (SEM). The results indicate that perceived usefulness, computer self-efficacy, and facilitating conditions are positively related to continued use and extended use of ES. However, neither continued use nor extended use is influenced by subjective norm. Additionally, users’ continued use is significantly related to extended use, and it partially mediates the relationships between extended use and its antecedents. The findings of this study contribute to the existing literature on ES usage behaviour in the post-adoption phase and in the mandatory organisational context. For practice, these findings should give managers a better understanding of the antecedents of ES usage behaviours, which would, in turn, help organisations to develop strategies that encourage their employees to maximise the use of ES in performing their tasks.

The author considers the peculiarities of impact of Motion Capture technology on the dynamic of development of artistic process in film art.
Micronutrient Deficiency in Women Living in Industrialized Countries During the Reproductive Years: Is there a Basis for Supplementation with Multiple Micronutrients?

Maternal diet is widely recognized to be one of the major environmental factors influencing the development of the embryo and fetus. It is important that women of childbearing age maintain good nutrition throughout their reproductive years, including before conception, as there is a strong relationship between fertility and a successful pregnancy, and a sufficient intake of micronutrients. Yet even in ‘high-income’, industrialized countries, where dietary resources are more readily available, micronutrient levels in such women may be inadequate. This review looked at the micronutrient status of women of childbearing age in industrialized countries, as well as those who were pregnant, to determine whether there are any gaps in micronutrient levels. A second objective was to assess whether the evidence indicates a role for multiple micronutrients other than folate and iron during these periods. Results indicated that although some women might have a sufficient intake of micronutrients (although not necessarily all of them), there are those who have lower than the currently-recommended daily intake of micronutrients, particularly folate, vitamin B12, vitamin D, calcium, iodine, iron and selenium. The evidence suggests that multiple micronutrient supplementation during the periconceptional period (i.e. before conception until the end of the first trimester) and throughout pregnancy could help to address inadequate dietary intake of micronutrients, improve maternal status prior to and during pregnancy, and thereby help to minimize reproductive risks.

Subclinical Hypothyroidism: is it Really Subclinical with Aging?

No recent study has focused on clinical features of subclinical hypothyroidism (SCH), especially in older patients. TSH measurement has remarkably evolved these last 20 years and thus reconsideration is needed. In our prospective multicenter study (2012-2014) including 807 subjects aged <60 years (<60y) and 531 subjects ≥60 years (≥60y), we have monitored 11 hypothyroidism-related clinical signs (hCS) together with TSH, FT4, FT3 and anti-thyroperoxidase antibodies values. hCS expression has been compared in patients with SCH vs euthyroidism in each age group. The number of hCS above 60y of age were found to be more elevated in the euthyroid population (1.9 vs 1.6, p<0.01) than in the SCH population (2.3 vs 2.6, p=0.41) while increase in hCS is limited to SCH subjects in the <60y group (p<0.01). The percentage of subjects with at least 3 signs increased with SCH in the <60y group (42.6% vs 25.0%, p<0.01) but not ≥60y (34.4% vs 33.9%, p=0.96). In older individuals, only three hCS could be related to both SCH and a decreased T3/T4-ratio (0.26 vs 0.27, p<0.01), suggesting either a reduced activity of TSH, or an adaptive response with aging. While hCS are clearly associated with SCH in patients <60y, they are not so informative in older subjects. TSH measurements carried out on the basis of hCS need to be interpreted with caution in aged patients. A reassessment of the TSH reference range in older patients is clearly needed and should be associated to more appropriate monitoring of thyroid dysfunction
Dermatoglyphics and ABO Blood Groups, an Observational Study

Objectives: (a) To study distribution of finger print pattern among the subjects having different ABO and Rh blood group and (b) Identify any relation between their characters and blood groups. Methods: 313 students at PIMS&RC were selected over a period of 6 months, their blood groups were ascertained and their finger prints studied. Fingerprints were grouped under 3 major categories, i.e. Loops, whorls and arches. Association was assessed statistically using chi-square test. Results: Male: female ratio was 1.8:1. Majority of the subjects (35.78%) in the study were of blood group O Positive followed by blood group B Positive, A Positive, AB Positive, O Negative, B Negative, A Negative and finally AB Negative, of whom 93.93% were Rh-positive. The general distribution of pattern of finger print showed high frequency (61.35%) of loops whereas whorls were moderate (35.14%) and arches were least (3.51%) in frequency. Almost same order was noticed in both Rh-positive and Rhnegative individuals or A, B, AB and O blood groups. Blood group O Positive showed more loops (62.86%) while, blood group B Negative had more whorls (55%) and blood group O Negative had more chances of having arches (6.67%) as compared to other blood groups. The ring finger more often has whorls (52.72%), where as the little finger more often has loops (79.23), both cases true irrespective of the blood group. Conclusion: The study suggests an association between finger print pattern and blood group. The distribution of different pattern of finger prints in individual fingers also showed some peculiarities in relation to blood group.
Operational Business Intelligence bei Call Centern: Erkenntnisse einer Fallstudienuntersuchung

In der Call Center-Branche konnen Informationssysteme (IS) des Business Intelligence (BI) mit ihren Monitoring- und Reporting-Funktionalitaten als Erganzung bestehender IS zur Erreichung einer konstanten Dienstleistungsqualitat beitragen. Insbesondere das operative BI setzt direkt an der Extraktion und Aufbereitung der Daten aus den operativen Call Center-Systemen an und kann dadurch sowohl Prozesstransparenz als auch Prozessfuhrung fur interne und externe Entscheider verbessern. Dazu untersucht der Beitrag die Funktionalitaten der fur die operative Entscheidungsunterstutzung eingesetzten IS sowie die zugrundeliegende Aufgabenverteilung bei sechs ausgewahlten Call Centern in Deutschland. Insgesamt zeigt die Call Center-Branche zwar erste Ansatze hin zu einem operativen BI, jedoch ergeben sich durch die Heterogenitat von Prozessen und IS sowie den Echtzeitanforderungen zur Datenauswertung weitere Perspektiven fur operative BI-Losungen.
La Funció ζ de Riemann

El novembre de 1859 Riemann envia un manuscrit de sis fulls a l'Academia de Berlin titulat «Sobre el nombre de primers menors que una quantitat donada», el qual seria l'unica publicacio dedicada a la teoria de nombres de tota la seva produccio cientifica. Aquest treball, sens dubte una de les peces mestres de les matematiques de tots els temps, es pioner en l'aplicacio de tecniques analitiques per a l'estudi de problemes aritmetics. Riemann hi introdueix la funcio ζ i en dona diverses propietats, de les quals treu consequencies sobre l'acumulacio dels nombres primers. Tambe hi enuncia la famosa conjectura sobre els seus zeros que ha passat a la historia amb el nom de hipotesi de Riemann , i que, havent resistit els esforcos de molts dels millors matematics del segle xx, es considerada avui dia el problema obert mes important de les matematiques. L'objectiu d'aquestes notes es explicar el contingut del treball de Riemann i el paper fonamental que ha tingut en l'estudi de la distribucio dels nombres primers.
