Performance is seen as multidimensional parameter by an organization, which can be managed in both a graphical and a transparent manner. Because managing performance targets in software engineering is so critically important, the historical data, analysis models, and tools that take into account the specifics of software development and maintenance must be available to the organization. In this paper, a white-box tool, “MultiPERF”, based on the international ISBSG Repository of software project data, is proposed for setting performance targets in software organizations.

BaPaMAN 1 (Binary Actuated Parallel MANipulator version 1) is a 3 degrees of freedom spatial parallel manipulator that has been designed and built within a collaboration between LARM Laboratory in Italy and IWF, Technical University of Braunschweig in Germany. This is a low-cost and easy-operation manipulator, whose functionality is based on stiffness of flexural joints and use of shape memory alloy actuators. Experimental tests have been carried out by using a high speed motion analysis equipment for workspace determination as based on image capture and position analysis.

This paper presents a comparison between three addition methods for the implementation of a Serial/Parallel Polynomial Multiplier. Each one of the chosen methods has its own strong points, depending on the number of digits taken into account per cycle. The LUT6 on Virtex-6 FPGA family has a major impact over the performance achieved and a change in the structure of a single addition cell might lead to impressive improvements. The architecture of the multiplier is presented together with the approach for each addition method. Finally, a comparison between the performances achieved in each implementation case is made, showing that the architecture mapped on the 6-LUT FPGA is the best for most of the cases.

We propose a method to rapidly launch new virtual machines (VM), starting from a prepared copy-on-write (COW) snapshot image. W e use RAM-disks instead of stored ones and apply the COW technique on them, also. A VM can extend its RAM-disk on non-volatile storage area when it grows over an established threshold, just to avoid overloading the RAM. Our solution is appropriate in situations like testing environments with short-living VMs, where the VM persistence is not a requirement, b u t one just needs to start very fast new running VMs in a known safe state. W e implemented our solution in QEMU/KVM. The performance tests showed an improvement in the total VM's creation and running time of about 15% over the basic HDD-based method.

The paper presents an practical analysis of combined DVB-C and IPTV implementation in an unique architecture. The advantages of each simple architecture are examined and the basic principles of unification are examined. Both aspects, client side and server side, are included in the analysis, and an implementation scenario with an evaluation of final costs for provider and client are established. In parallel, we are presenting an enhanced architecture to teach and implement some practical scenarios. This architecture is used to teach and experiment the basic concepts of DVB-C and IPTV streaming. It is possible also to estimate some crucial elements like QoS and QoE in different scenarios of distribution. The conclusion of the research is that it is possible to implement hybrid distribution (IPTV and DVB-C) gradually and with minimal costs, sharing the infrastructure. In the same time a hybrid architecture can offer immediately additional services like Internet access.

It is necessary to maintain the constant temperature around 20 Celsius degree with a maximum deviation of 4 Celsius degree in Datacenter to work in the best condition. In this aim, two software were developed in INCDTIM for control and monitoring the important environmental parameters. These applications directly communicate with an equipment hardware that consists from an electronic board called "AVR_NET_IO" with its own firmware using a microcontroller ATmega32 type. Using these control system it is possible to monitor the temperature variation in Datacenter, the active power on a long period and it will be possible to reduce the energy consumption.

Several techniques to generate the chirp signal have been proposed over the past few decades. Generally, the techniques can be categorized into analog approach and digital approach. In analog chirp generator usually a voltage controlled oscillator is used to generate the chirp signal. However, due to several limitations of this oscillator the digital approach has slowly takes the role as the chirp generator, although are more complex and hard to realize. This work proposes an easy to use analog alternative for chirp signal generator, which counteracts the claimed disadvantages. The paper presents the principle of the proposed generator, the simulation scheme with the simulation results and an experimental result, highlighting the advantages of the method.

Product-driven manufacturing has gained a lot of traction recently among practitioners as it has the potential to take flexibility and agility of the manufacturing system to a new level compared to hierarchical control models. The advances in embedded technology have created the premises for the emergence of truly intelligent products that are capable not only of identification and information storage, but also of complex behavior and local decision making. In this context, this paper proposes a multi-agent control system that aims to solve the new challenges introduced by the shift to product-driven manufacturing, specifically addressing the special needs for information flow between shop floor entities and the MES system. The paper presents the pilot implementation, using the JADE multi-agent platform, a backtracking scheduler, an artificial neural network (ANN) for local decision making and the experimental results outlining the agent processing requirements during the product lifecycle.

This work presents a novel observer design for nonlinear descriptor systems using their Takagi-Sugeno representation. The approach allows obtaining more relaxed results than previous literature by changing the extended estimated state vector; this step permits using a full observer gain. The obtained conditions are pure LMI. Moreover, previous results are always included by the new ones. An example illustrates the benefits of the proposed method.

It becomes more and more often that the improvement of the manufacturing processes imply using the statistical process control. The companies understand that by reducing the variation in a system the quality will improve and the competitiveness will also increase. It is not important only to produce parts according to the specifications, but is very important that the output of the process is between some limits, named specification limits. The present paper presents a case study from wood production industry. The simulations were done with Minitab software, but they can be done with the help of other similar software.
