Résumé :
Activity monitoring is a technique for assessing the physical activity that a person undertakes over some time. Activity Index (AI) is a metric that summarizes the raw measurements from tri-axial accelerometers, often used for measuring physical activity. Our research compared the Activity Index for different activity groups and hand usage [1]. We also tested this metric as a classification feature, and how different data acquisition and segmentation parameter configurations influence classification accuracy. Data acquisition was done with a previously developed system that includes a smartwat

In this study, information from surface electromyogram (sEMG) signals was used to recognize cigarette smoking. The sEMG signals collected from lower arm were used in two different ways: (1) as an individual predictor of smoking activity and (2) as an additional sensor/modality along with the inertial measurement unit (IMU) to augment recognition performance. A convolutional and a recurrent neural network were utilized to recognize smoking-related hand gestures.

In recent years, much effort has been devoted to the development of applications capable of detecting different types of human activity. In this field, fall detection is particularly relevant, especially for the elderly. On the one hand, some applications use wearable sensors that are integrated into cell phones, necklaces or smart bracelets to detect sudden movements of the person wearing the device. The main drawback of these types of systems is that these devices must be placed on a person’s body. This is a major drawback because they can be uncomfortable, in addition to the fact that these

First, visible light images are sensitive to illumination changes and background clutter. Second, the 3D structural information of the scene is lost when projecting the 3D world to 2D images. Recovering the 3D information from 2D images is a challenging problem. Range sensors have existed for over thirty years, which capture 3D characteristics of the scene.

Résumé :
AbstractThis chapter focuses on the legal activism that followed the Ali Enterprises factory fire and its aftermath in Pakistan. This chapter has two purposes: firstly, it documents the legal proceedings that were initiated and pursued in the courts of Pakistan as well as its interconnected developments. Secondly, I aim to use this engagement with the legal proceedings of the Baldia factory fire aftermath as an opportunity for an in-depth reflection on the capacity and, finally, suitability of the judicial process to bring about justice in struggles over human and labour rights. Providing a rare and insider account of the legal proceedings in the Pakistani courts and its interconnected developments, I hope to lay the empirical foundation for the theoretical and strategic claims of this study. It is against the background and based on the experience with the litigation and legal advocacy following the Baldia fire that I examine the two what I perceive as “paradoxes” at the heart of the litigation. The first is the inseparability of the “limited justice” that may result from such litigation on one hand, and the “structural injustice” that informs and determines the conditions the litigation seeks to address—and transform—on the other hand. The second paradox concerns the inseparability of both law and lawlessness as regards the legal context of the litigation, advocacy and policy proposal elements that are here in play.My argument is that these apparently contradictory phenomena not only coexist alongside one another but that they guarantee each other’s existence. This analysis leads me to the conclusion that in order to understand and improve such forms of strategic litigation, it is necessary to measure its success and failure in terms of three distinct but interconnected criteria. These are the tactical, strategic and structural impacts of the litigation. Ultimately, I will argue for rejecting what is often perceived by involved stakeholders to be an unavoidable choice between nihilism, euphoria or incremental reform in this context. But, to the contrary, I will argue for a conception of legal struggles as a means of building sustainable and fruitful forms of resistance and of change based on the recognition and exploitation of these irreconcilable paradoxes rather than fruitless attempts to ignore or transcend these irreconcilable contradictions.

Résumé :
RGBD-based activity recognition is quite an interesting task in computer vision. Inspired by the exemplary results obtained from automatic features learning from RGBD data, in this work a six-stream CNN fusion approach has been addressed, which is developed on 2D-convolution neural network (2DCNN) and spatial-temporal 3D-convolution neural networks (ST3DCNN). The proposed approach has six streams and runs in parallel, where the first and second streams are used to extract space and time features with the help of a ST3DCNN model. Similarly, the remaining four streams have been used to extract the temporal features by means of two motion templates on motion history image (MHI) and motion energy image (MEI) via a 2DCNN. Further, a support vector machine (SVM) is employed to generate the score from each stream. Finally, a decision level fusion scheme particularly a weighted product model (WPM) to fuse the scores is obtained from all the streams. The effectiveness of the proposed approach has been tested on popular benchmark public datasets, namely UTD-MHAD, and gives promising results.

Résumé :
Acute respiratory infections (ARI) are infectious diseases of the respiratory tract caused by viruses, bacteria, and atypical bacteria. They range in severity and even mild cases may cause a significant reduction in workplace productivity. ARIs commonly occur in outbreaks and disproportionally impact workers in occupations where workers are in close proximity to co-workers, members of the public, or where they reside in densely populated housing. High-risk workers include those in the healthcare sector, protective service, food and meat processing, service, and education industries. A person can become infected by inhaling virus-laden aerosols, having virus-contaminated sprayborne drops impinge on exposed mucous membranes, and touching contaminated surfaces followed by self-inoculation. More than one transfer process may be involved in the transmission, and the dominant route may differ for different causative agents, environments, and activity patterns. Preventing ARI transmission in the workplace must be holistic in approach and begin with anticipation and recognition of potential risks, reinforced by the continuous evaluation and implementation of control strategies. Control measures should be layered and multiple routes of transmission should be addressed. Controls should be adapted to the specific workplace and the ARI to prevent pathogen introduction, rapidly detect cases, and promptly eliminate exposure. Prevention and control can be accomplished by promoting vaccination, improving ventilation and air cleaning, providing paid sick leave, flexible working conditions, and work-from-home options. Promoting hand sanitation and providing appropriate personal protective equipment are important but never sufficient in isolation. Occupational health professionals should partner with workplace engineers and human resource departments to design effective programs.

Résumé :
As an emerging human-computer interaction (HCI) technology, recognition of human hand gesture is considered a very powerful means for human intention reading. To construct a system with a reliable and robust hand gesture recognition algorithm, it is necessary to resolve several major difficulties of hand gesture recognition, such as inter-person variation, intra-person variation, and false positive error caused by meaningless hand gestures. This paper proposes a learning algorithm and also a classification technique, based on multivariate fuzzy decision tree (MFDT). Efficient control of a fuzzified decision boundary in the MFDT leads to reduction of intra-person variation, while proper selection of a user dependent (UD) recognition model contributes to minimization of inter-person variation. The proposed method is tested first by using two benchmark data sets in UCI Machine Learning Repository and then by a hand gesture data set obtained from 10 people for 15 days. The experimental results show a discernibly enhanced classification performance as well as user adaptation capability of the proposed algorithm.

We propose a computer-vision-based detection and recognition system which can be used in the banks to detect the anomalous activity of bank robbery. We propose CCTV based robbery detection along with tracking of thieves. We have used computer vision to detect theft and robbers in CCTV footage, without the use of sensors. This system concentrates on object detection. This detection of bank robbery is done based on detecting components, which are prohibited by using in the banks and are common in robbery, like handguns, a person wearing a helmet or a ski mask which comes under the object detection. Apart from these, recognition is done on the human postures like raising hands and kneel down which comes under the posture detection. The security official will be notified about the suspicious event by using Real-time analysis of the movement of any human from CCTV footage and thus gives a chance to avert the same, so that necessary action will be taken by the authority and prevent threat to bank as well as to the human life presents there.

Résumé :
Conventional access control solutions rely on a single authentication to verify a user’s identity but do nothing to ensure the authenticated user is indeed the same person using the system afterwards. Without continuous monitoring, unauthorized individuals have an opportunity to “hijack” or “tailgate” the original user’s session. Continuous authentication attempts to remedy this security loophole. Biometrics is an attractive solution for continuous authentication as it is unobtrusive yet still highly accurate. This allows the authorized user to continue about his routine but quickly detects and blocks intruders. This chapter outlines the components of a multi-biometric based continuous authentication system. Our application employs a biometric hand-off strategy where in the first authentication step a strong biometric robustly identifies the user and then hands control to a less computationally intensive face recognition and tracking system that continuously monitors the presence of the user. Using multiple biometrics allows the system to benefit from the strengths of each modality. Since face verification accuracy degrades as more time elapses between the training stage and operation time, our proposed hand-off strategy permits continuous robust face verification with relatively simple and computationally efficient classifiers. We provide a detailed evaluation of verification performance using different pattern classification algorithms and show that the final multi-modal biometric hand-off scheme yields high verification performance.

Résumé :
This chapter explores how, when John Roy Lynch came to Chicago, whether or not he should take an active part in politics was one of the first questions that occurred to him. He had no intention of actively participating politically in local matters, but it occurred to him that like some other retired army officers, he could, with propriety, take an active part in national matters. But after going over the field very carefully, Lynch found that conditions nationally, as well as locally, were not such as would justify him in doing so. In fact, beginning with the unfortunate administration of President William Howard Taft, the colored American had no standing with either of the two major parties. The Democratic party, nationally, was still a white man's party and, beginning with the Taft administration, the Republican party was no longer a champion of human rights. In fact, the policy inaugurated by President Taft was equivalent to transforming the Republican party, as far as it was in the power of an administration to do so, into a race proscriptive party. In other words, racial identity regardless of merit was made a bar to official recognition.

Résumé :
In the conditions of a complex criminogenic situation, a high level of preparedness of police officers for effective actions in regular and extreme conditions is extremely important for successfully solving the tasks of ensuring proper law and order and public safety in the state. The professional training of employees is a decisive factor in the quality of law enforcement activities, ensuring legality in maintaining law and order and fighting crime.A high level of physical training as a component of professional training guarantees the effectiveness of operational and service tasks, ensuring the personal safety of the police officer and his surroundings.In modern society, it is no longer a secret for anyone how important it is for every person to be in good physical shape. The need for this is caused by the rhythm of modern life, new opportunities and challenges of today, and even the fashion for a healthy lifestyle. After all, with the development of society, new relationships also develop, the criminal world also actively uses new opportunities and gaps in the legislation, unprofessional actions or insufficient preparation of employees of the Security Service.Thus, the presence of a high level of physical training, perfect mastery of techniques and tactics for the application of measures of physical influence, self-defense skills and techniques of hand-to-hand combat in regular and extreme conditions of operational-service activity is the professional duty of every police officer.We can come to the conclusion that the level of physical training as a component of professional training affects the effectiveness of operational-service tasks, ensures the personal safety of the police officer and his environment, and therefore requires constant improvement and scientific research. The purpose of the research is the theoretical analysis and synthesis of scientific and methodical literature on the researched topic, as well as the expert examination of the preparedness of the first-year cadets of the Dnipropetrovsk State University of Internal Affairs. The following research methods were used to implement the tasks and achieve the goal: analysis of literary sources; synthesis of literary sources; generalization of literary sources; pedagogical observation; control exercises (tests); assessment of testing levels; mathematical statistics.In order to successfully solve the tasks for physical training classes, the motivational levers of the stable evaluation system, namely the “Scale for evaluating the results of physical training tests” were used. Resultsthe analysis of scientific and methodical literature and documents that regulate the educational process in special higher educational institutions of the armed forces gave reasons to assert that proper physical training is an important prerequisite for high-quality professional preparation of graduates of these universities for practical activities. At the same time, the problem of improving the quality of physical training of cadets in higher educational institutions of the Ministry of Internal Affairs of Ukraine, despite a significant number of developments, remains insufficiently studied.Taking into account the need for police officers to engage in confrontations with aggressive and, as a rule, well-trained violators, the problem of special physical training of cadets of higher educational institutions of the National Police of Ukraine has become extremely urgent.Also, based on our research, we can conclude that due to high workload, cadets do not have the opportunity to regularly engage in physical training and improve their physical level, and classes according to the educational and methodological plan cannot fully develop physical qualities cadets, that is why we see an insufficient development of strength in the cadets of the first year of the DDUVS. This is evidenced by the fact that, according to our research, only 32% (n = 8) of the subjects have an excellent level. Good was noted in 40% (n = 10), and a satisfactory level of strength development was found in 28% (n = 7) of the cadets. Practical implications. The scientific novelty of the obtained results lies in the fact that a complex theoretical and applied monodisciplinary study was conducted, dedicated to solving scientific and practical problems of the state of physical training of first-year cadets of the Dnipropetrovsk State University of Internal Affairs. Value/originality. The obtained research results can be used to improve the level of physical training of cadets of the National Police of Ukraine.

Résumé :
An urgent lesson learned from Fukushima Daiichi accident is what can happen by natural disaster can also occur by human design. The accident raised a fear that terrorists could cause a similar accident by acts of sabotage against nuclear power plant (NPP) and it is noticeable that threats of terrorism for nuclear security are increased after the accident. When considering sabotage, the prime threat to nuclear power plants, due attention should be paid to sabotage by insiders. Generally, insiders are the individuals with authorized access to nuclear facilities in transport who could attempt una
