This paper aims at solving an unbalanced assignment problem using the WinQSB software. Starting from the consideration that the assignment problem is an extension of the transport problem, the problem is solved in two ways, as an assignment problem, using the hungarian method and as a transport problem.

The disponibility in high quality expertise becomes an important tool for getting active and implementation of the acquis communautaire requirements. Expertise rightly, has established place in the arsenal of evidence and believe that with the evolution of scientific and technical progress, its role will increase being permanently. Therefore, at present, the greater the role of defining the technical expertise judicial recordsis, since the causes are complex and contain a large amount of technical and financial data. Also, now new forms of expertise, progress and developments leading contemporary science research and investigative methods, and methods for resolving technical issues expert, hence the urgent need of an effective quality management technical expertise judicial activities.

The first part of the paper summarizes several structural versions of biomechanisms specific to the human upper limb, focusing on the basic anatomical movements and on the degrees of freedom number. These biomechanisms coincide with the structural diagrams of several different versions of exoskeletons. The second part of the paper presents the kinematic modeling for three different versions of 3 DOF rehabilitation robotic exoskeletons.

This paper aims at solving a job shop scheduling problem of 3 tasks with different execution sequences of operations on 3 machines. The Shortest Processing Time rule is used, because this rule minimizes the average proccesing time of a set of tasks. It is then converted to a CPM network. The software Lekin is used for establishing the execution launch sequence of tasks, and for solving the CPM problem, the WinQSB software.

The state of stress and deflection for the flexible wheel are analyzed accepting a simple model both by analytically procedures (strain energy equation) and numerical method (Finite Element Application). We compare the results given by the two procedures.

The paper presents a proposed method for underlying the presence of tangential percussions occurring in multibody systems. Tangential percussions define a relatively newly introduced concept required by the necessity of explaining the sudden change in the state of motion for two bodies interacting only on a direction from the common tangent plane. In robotics domain, normal and tangential percussions are widely met in the case of robotic hands in the moment of contacting the manipulated object.

This paper presents a geometrical and topological structure analysis for a spatial parallel manipulator (PMP), referring to the calculation of mobility (degree of freedom) of these types of complex mechanisms. In this paper it is used a new formula to calculate the mobility according to the number of drivelines, which are considered having identical operations. Also, in this paper it is used the bars method for the direct kinematics analysis of parallel manipulator with three actuators and after that it is analyzed an example solved by means of specialized software.

If we make a brief scan of the field known as Medical Robotics, we find that in recent years there has been an impetuous development of applications involving medical robots.

The main reason for exploring legged robots is the flexibility of mobility on difficult terrain, where wheeled robots cannot go. Wheels excel on flat surfaces or specially prepared surfaces, but they do not perform well when terrain is uneven, which is the case in real life, legged robots becoming more interesting to research and explore. In this paper some information about the mechanical design and kinematics of a small hexapod walking robot based on a Scotch Yoke mechanism leg are presented.

In this paper, for a useful working basis, including for the promotion of new redundant structures, beyond those already implemented, there is a systematization of kinematic chain structures with 7 and 8 axes. Representation of corresponding workspaces can help the designer in choosing the structure with maximum functionality for a given application. Exemplifying of the use of these redundant structures, namely a structure with 7 axes, is possible presenting the seven-axes robot CLOOS.

Joule-heat induced temperature changes during the austenite - martensite hysteresis transition and may cause contraction of SMA-wires and a change of wire resistance as well. The contractions of those current-heated SMA wires are now exploited to move a small robot arm with four degrees of freedom. Encoders for position feedback as normally used in actuator systems are not used here. Position detection is accomplished through the analysis of the wire resistance.

This paper is conceived to be a synthesis of opinions and contributions used in understanding the managers’ roles and missions from contemporary organizations. The discoveries belong to the authors as a result of observations and thematically directed discussions with some managers, from the different hierarchic levels from different organizations, different property types and different forms of organization, administration and management from the Caras-Severin County. We consider that these contributions and opinions may represent the basis of further researches that are proposed for the analysis of the managers’ work efficiency and the efficiency of organization managed during the present and in the future, characterized by profound changes and by a turbulent ambient environment.

Throughout the process of designing and running of mechanical devices, estimating the friction force and torque is essential. For the dry friction case, the problem is more complex due to the occurrence of two friction coefficients, static and dynamic, respectively. The paper present a rapid methodology and the test rig utilized for finding the dynamic dry friction coefficient. The experimental data obtained highlight the precision of the proposed method.
