Proactive principle can be used not only in large distributed solution for medical centers, but it can be found usable in a many other solutions. One of them we found in an application to allow for people have a happy wake up. A mobile device application was developed to solve a problem of bad wake up at morning for all the people. Sleep is a complex process regulated with our brain and as such is driven by 24 hour biological rhythm. Our biological clocks are controlled by chemical substances that are mostly known to us. wakeNsmile application is developed to react on users declared request in form of happy wake up at predefined time (Fig. 1). The time defined for alarm is however the latest possible time to wake up of user. We are trying to detect a body state in which the user is most able to wake up with a smile. Time period for detection analysis of state phases is declared to 30 minutes. A Fast Fourier Transformation (FFT) and some other sophisticated methods are used for it. © 2010 IEEE.

According to the intelligent behavior of social population, a novel particle swarm optimization algorithm based on predatory search strategy (PS-CPSO) is proposed by introducing the centroid of particle swarm in the standard particle swarm optimization model to improve global optimum efficiency and accuracy of algorithm. Results of Benchmark function simulation and material balance computation (MBC) in alumina production show that the new method not only improves the local searching efficiency and global searching performance greatly, but also has faster convergence speed and higher precision, and can avoid the premature convergence problem effectively. ©2010 IEEE.

Pre-operative planning in orthopedic surgery is essential to identify the optimal surgical considerations for each patient-specific case. Estimation of the three-dimensional (3D) pose of bones plays an important role in computer assisted diagnosis and surgery. However, understanding the 3D pose of femoral fractures on plain radiographs is challenging, and 3D imaging modalities such as Computed Tomography (CT) are still being restricted to a minority of complex orthopedic procedures. Although the existing application has focused on registering a 3D model of the bone to the images of the same bone intra-operatively, pre-operative 3D pose estimation is more valuable for surgery planning. This paper proposes a method for recovering 3D pose by registering a preoperatively prepared generic 3D model of a bone to bi-planar (frontal and lateral) digital radiographs (DR images) of different patients. It can perform 3D-2D registration with unknown correspondence automatically without invasive external fiducial markers. This 3D-2D registration will identify the position and orientation of the femur in six degrees (Rx,Ry,R z,tx,ty,tz) of freedom. Validation results using different femurs show that this method is robust and accurate in estimating the 3D pose of femurs in bi-planar radiographs of different patients. © 2013 Springer-Verlag.

This paper proposes an approach to algorithmically synthesize control strategies for discrete-time nonlinear uncertain systems based on reachable set computations using the ellipsoidal calculus. For given ellipsoidal initial sets and bounded ellipsoidal disturbances, the proposed algorithm iterates over conservatively approximating and LMI-constrained optimization problems to compute stabilizing controllers. The method uses first-order Taylor approximation of the nonlinear dynamics and a conservative approximation of the Lagrange remainder. An example for illustration is included. © IFAC.

Systems and control are all around us. System view, understanding systems and how they are controlled is important for everyone. The behavior of systems is determined by some fundamental principles which can be understood by everyone. The main principles governing systems and control are presented on different levels. The first level is dedicated for everyone. Comics-like interpretation is provided with explanations. The second level discusses the main topics dedicated for the interested students. Several case studies demonstrate how system view is considered in different areas of life. With this approach systems in different areas of life could be better understood contributing to better decisions influencing their performance. The third level provides deeper insight into some aspects of modern mathematical system theory, to geometric view of control systems. The material is available on a website on the internet. © 2016

The service-oriented environment offers the opportunity to create new applications, by combining existing applications offered as services, in order to react to the business' increasing pressure of quickly delivering new applications. With a large number of web services offering the same functionality, choosing the web services that meet best the client's quality of service (QoS) requirements is a very important task. We introduce a QoS-aware end to end web service composition approach that handles all the stages from the web service discovery step, to the actual binding of the services. This approach uses our method of expressing nonfunctional preferences, which requires minimal effort on the part of the clients, but offers great flexibility in managing trade-offs. We define a QoS preferences ontology and use it in our semantic web service selection to choose an initial candidate list of services for every task in the orchestration model. Then, one concrete service is chosen from each candidate list and is boand to the corresponding task. This step involves computing and comparing the aggregated QoS of the resulting composite services. The selection is performed using a genetic algorithm.

International Conference on control Systems and computer science (CSCS)

Current concerns about data privacy have lead to increased focus on data anonymization methods. Differential privacy is a new mechanism that offers formal guarantees about anonymization strength. The main challenge when using differential privacy consists in the difficulty in designing correct algorithms when operating on complex data types. One such data type is sequential data, which is used to model many actions like location or browsing history. We propose a new differential privacy algorithm for short sequence counting called Recursive Budget Allocation (RBA). We show that RBA leads to lower relative errors than current state of the art techniques. In addition, it can also be used to improve relative errors for generic differential privacy algorithms which operate on data trees.

In this commentary article, we outline research challenges and possible directions for the potential applications of AI in the judicial domain by specifically considering process analysis in the Italian context. Applying AI to process analysis poses several challenges, including information extraction from legacy information systems and analysis of legal documents, process modeling with a particular emphasis on temporal analysis, real-time process monitoring, conformance and compliance checking, predictive techniques for accurate predictions, and analysis of judges' workload. Solutions to these challenges include methods and tools for data identification and collection, innovative approaches to process modeling, reactive techniques for real-time monitoring, conformance checking with explainability, language models adapted to specific domains, and the identification of suitable indicators for the analysis of case handling efficiency and case classification.

In densely populated countries, medical facilities are not much available in country-side areas. If it is about animal health, it is rare to get a good cure. The owner has to take the animal to the Vet and will have to do it every time if he is living in remote places. Most countries in South Asia have this situation where animal husbandry is a common source of earning bread. Many times either the animal is not getting cure on time or diseases are detected at a later stage which harms them most. This paper describes a cellular communication based mobile system which can be used to monitor the health of animals in the remote country-side area. Also, the owner can get a prescription from the doctor and cure animals according to doctor’s advice. The developed system uses client-server model and can work for multiple patients who are connected with the same doctor. The Vet can access this system on his PDA or desktop using a web application. © 2018, Pleiades Publishing, Ltd.
