The cooperation of the analog and digital circuits and the embedded controllers as well as their industrial use and technical application have always been in the focus of our interest. In reconfigurable systems the effectiveness and quality of the analog circuit system can be maintained and modified by circuit or by changing the single element values. There are further advantages of the programmable analog circuit applications; more compact, more reliable, more flexible systems can be produced with better performance. It is especially beneficial if for programming we modify the function of a programmable analog circuit either giving a new topology or a new component parameter using the flexibility of the microcontroller.

Nowadays more and more technical systems will directly interfere with the everyday life of people, sometimes this can cause conflicts, which is caused by the intelligence given to the machine. The humans will not give only command to the machine but also the machine can decide itself how to handle a given situation. What is important that in this relationship the intelligent machine will not cause uncertain or dangerous situations. A very important field, where this problem is thoroughly investigated is the field of intelligent vehicle system. This paper gives an insight to the legislation process of the electronic stability control system and other, similar intelligent vehicle systems. Particulary, how the international legislation bodies (primarily the ECE-UN working party 29) approach this problem on example of the mentioned systems.

The payment of the utilities: gas, electricity, water, mobile and fixed phones, internet, TV, insurance, local taxes, etc. benefits by multiple solutions. These solutions split in two categories: IT based (online) payment methods and outside payments methods, at different pay points. This research presents a solution, web-based and mobile based, for paying and managing the utilities that involves an online method which has an novel concept. This method is transparent to the users and involves almost zero time spent for payments and smaller costs generated by commissions than in other existing payment methods.

Genetic algorithms (GA) are one of the most successful techniques in solving combinatorial optimization problems. Its general character has enabled its application to different types of problems: vehicle routing, planning, scheduling, etc. This article shows that there is controversy in the basic structure of the algorithm steps when it is applied at routing problems. Specifically in this paper we show that the crossover (CX) offers no advantage in the optimization process. To solve such problems, the most important steps are mutation and selection of individuals. These two steps are what help to analyze the solution space exhaustively and give GA optimization capability. To prove our hypothesis we will analyze the results obtained by applying different blind crossover operators to solve multiple instances of the TSP (Travelling Salesman Problem).

This paper proposes a navigation algorithm that allows mobile robots that participate in different missions to move in unknown environment. The algorithm uses data from the sonar or from the infrared sensors mounted on the robots and data from the video camera with which the robots are equipped. Using the video camera the robots will be able to detect and classify different traffic signs that can help the robots to arrive the target points safely and in a short time. The algorithm includes a convolutional neural network with six layers to classify the traffic signs. Several simulations were run on the nRobotic platform developed at the “Politehnica” University of Timisoara, Romania, to validate the new algorithm. The simulation scenarios illustrate attractive mechatronics applications concerning the behaviors of robots in unknown environments in the presence of multiple traffic signs.

Cloud computing represents a different paradigm in distributed computing that involves more and more researchers. In this context, we can see that there is a need for knowing where and when a certain data is processed or stored. Compared with classic digital forensic, the field of cloud forensic poses a lot of difficulties since data is not stored on a single storage unit and furthermore it involves the use of virtualization technologies. In this paper we will present in detail a new and novel way of monitoring user activity in cloud environments using a secure cloud forensic framework. We talk about the architecture of such framework and we emphasize the way in which our research can be applied on top of new or existing cloud infrastructures. Also, for testing purposes, we have applied our findings over our previous developed cloud computing framework.

The aim of this research is to study parameters influence in the electric arc modeling. In order to perform this, a study of the electric arc behavior was made by implementing three models of the electric arc in the Matlab/Simulink environment. Furthermore, graphical user interfaces in Matlab were developed, the purpose being to obtain the dynamic voltage-current characteristic of the electric arc. Both, simulated and measured data were compared and presented in this research. From an AC electric arc furnace, having the capacities of 100 tones, fed by medium voltage, the measured data were acquired using the data acquisition board, ADA3100.

In recent years cloud computing has taken off and has become an underlying technology in many online applications and websites, whether using a private or public cloud. At the same time with the increase in globalization, online collaborative tools have become very important in order to allow different businesses to communicate with each other, or even different parts of the same company to communicate more easily and share data. Previous work introduced an architecture for a geographically distributed, cloud based collaboration application. While the architecture allowed the scaling up and down of the number of cloud instances being used to host media servers, no control scheme for such cloud scaling was provided. In this paper a model and control scheme for cloud scaling for a collaboration application is provided. The model is based on the leaky bucket model commonly used in network control, while the control system is a self-organizing system. A testbed for the architecture is also presented and used in order to gather performance data from the collaborative application.

Cancer fighting treatments are expanding, and a promising type, targeted molecular therapies have a new approach. The aim of these therapies is not to eliminate the whole tumor, but to control the tumor into a given state and keep it there. Explicit knowledge of tumor growth dynamics and the effects of targeted molecular therapies is crucial in tumor treatment development. We show the results of mouse experiments where tumor growth was investigated in case of C38 colon adenocarcinoma and B16 melanoma. Several curves were fitted and tumor growth dynamics was examined. Three attributes of tumor were measured: tumor volume, tumor mass and vascularization; and tumor growth dynamics was examined. Tumor volume was measured with digital caliper, vascularization was investigated with CD31 antibody immunohistochemistry staining on frozen sections. The relationship between these tumor attributes were examined with linear regression analysis. The dynamics of tumor growth was identified as a second order linear system.

In the heterogeneous mobile networks of the future, the mobile users, equipped with multi-mode terminals, will be able to select the radio network that suits best the needs of the mobile user and of the applications running on the mobile terminal. In this work we propose a novel network selection algorithm based on fuzzy inference. Our algorithm permits a prioritization of the users by using different fuzzy rules for each class of users. We investigate by simulation the efficiency of our algorithm and compare its results with an existing network selection algorithm, called consumer surplus.
