Collaborative filtering (CF) is one of the most popular and efficient recommendation methods, and matrix factorization is considered a useful technique to implement CF-based systems. To scale up the matrix factorization method for large datasets, many parallel computing techniques have been proposed. In this study, we present a new approach with different data distribution schemes to fully exploit the computing power and the memory capacity of the cloud computing platform. In addition, we perform several sets of experiments to evaluate the developed approach in a cloud computing environment, and the results show its feasibility and effectiveness.

It is critical for a machine equipped with the battery of limited energy to transmit data with shorter delay in machine type communication networks because the machine in an energy-insufficient state does not send data immediately. Although a machine can equip the capability of radio frequency (RF) energy harvesting, there is a trade-off between RF energy-harvesting rate and the opportunity to send data in a radio band. Therefore, we propose a spectrum hand-off for energy harvesting in cognitive radio based machine type communication networks. Using the proposed spectrum hand-off, a machine can determine (i) the appropriate time that a machine harvests RF energy from which radio band and (ii) the time to send data or sleep such that more energy is gathered from two radio bands and then more data is sent in shorter waiting time. Simulation results show that the proposed spectrum hand-off can yield lower mean packet request delay in light and middle load and increase utilization of time slots (or throughput).

The stability degree of a stable control system is defined to be the negative of the largest real part of the zeros of its characteristic equation. In this paper, we consider the problem of tuning parameters of PID controller for delay-free linear time-invariant systems to maximize the degree of closed-loop stability. By applying the Bernstein branch-and-bound (BBB) method to test the existence of the stable region in the parameter space, a procedure is proposed to design maximum-stability PID controllers for linear time-invariant delay-free systems. The applicability of the BBB method here is based on fact that the stable region is characterized by a set of multi-variate polynomials in parameters, which is derived from the Lienard-Chipart criterion for a Hurwitz polynomial. An example of designing a PD controller with maximum stability-degree for a fourth-order system is given to verify the proposed approach.

As the demand for data storage is growing exponentially, higher density and durable storage solutions are necessary. DNA has many potential advantages as a medium for information storage because it is extremely dense, high capacity, low-maintenance and durability. Previous research has focused on ASCII code files or pictures, which ignored expression with other languages encoded with Unicode. We provide a DNA translator for multiple languages and also discuss the influence of entropy in different dataset. The effect of Huffman code encoding and ternary code encoding for different dataset are also compared. Our results indicate that the DNA memory translator system is very efficient for the dataset with low entropy.

This work aims at integrating fuzzy logic and quality function deployment (QFD) technique to determine the critical chain in a project with uncertainties. The degree of fuzziness of every activity in a project is defined and calculated by QFD so as to (1) evaluate the effects of project uncertainties, (2) select adaptively the fuzzy logic model, and (3) calculate the buffer time of the critical chain. The example of a project with 11 activities facing 6 uncertainties: project time limit, activity begin time, budget, manpower, technical difficulty, and facility requirement is applied to demonstrate the effectiveness of the model integrating fuzzy logic and QFD. Analysis shows that project scheduling by this proposed integration is superior to that by Project Evaluation and Review Technique (PERT) and by the conventional critical chain method. Not only the scheduling is more efficient, but also the buffer time in critical chain can be systematically determined to accommodate the uncertainties.

Industry 4.0 is characterized by intensive digitization of production and equipping the machines with a high use of ICT (information and communication technology. However, the fourth industrial revolution brings with it more security-related challenges. It is important to engineer, industrial solutions that design, build and run Industry 4.0-systems securely, reliably and effectively. Moreover, industrial systems are designed according to the new characteristics enabling connecting and interacting with other Industry 4.0-systems in a reliable manner. Furthermore, it is essential to consider the new innovative business models by designing these systems. The digital data and knowhow in companies are the most valuable assets and thus should be protected. This data are the new trade ware by many businesses and add new values to companies. In this paper, one of these models that are based on online-trading of technology data, is considered. Technology data are defined as machine's functioning parameters that are required to ensure a smooth operation of machines under different circumstances. The focus is to develop an Industry 4.0-capable machine with the new characteristics that an Industry 4.0-system have. The security concepts for protecting the technology data by designing and manufacturing the machine will be validated by means of a use case of participating in a technology data marketplace.

The left ventricular assist device (LVADs) have been used as either a bridge to transplant or destination therapy for end stage heart failure. The continuous-flow models have been used with multiple complications. This project applied electromagnetically driven pump to the development of a heart-rate synchronized pulsatile LVAD. A control system was developed based on LabVIEW programming platform. The LabVIEW program receives pulse signals by DAQ device and then output the signal to control the coil of the pump by DAQ device. Under the action of the magnetic effect of electric current, thus the magnetic piston inside the pump is pushed back and forth. The program not only receives pulse signals but also synchronizes the pump and pulsation. The researchers used heart mock to test the flow situation of water. According to the current situation, the pump can affect the water flow. Currently, the experiment enters the stage that cooperates with Keelung Chang Gung Memorial Hospital. In addition, the circuit is miniaturized and the connector is used for experimental convenience in the hospital in the future.

Clock skew minimization is a very important task for sequential timing optimization. As the technology node continues to shrink, the clock skew caused by the effects of process/voltage/temperature (PVT) variations may result in a serious problem. To deal with this problem, the previous work proposed a self-adjusting mechanism to dynamically control the clock skew. However, the previous work requires a lot of clock buffers for dynamic clock skew control. In this paper, we present a new mechanism for the selection of the channels of adjustable-delay-buffers (ADBs). Based on the proposed new mechanism, a lot of clock buffers in the ADBs can be saved. Experimental results consistently show that our approach works well in practice.

A MapReduce cloud becomes the essential platform in the cloud computing infrastructure today. Because applications may process input data with different algorithms and logics to produce intermediate data, a MapReduce cloud may suffer intermediate data skew by unevenly distributing intermediate data among nodes at run time. When intermediate data skew happens, a MapReduce cloud not only idles nodes to waste computation resources but also prolongs the application execution progress to hurt user experiences in cloud computing. Instead of the existing solutions that assume many available idle nodes and use computation resources in a loose way, a MapReduce cloud can use the Workload Alleviation Scheduling Framework (W ASF) proposed in this paper to alleviate the negative performance impact of intermediate data skew in a small-scale MapReduce cloud by smartly utilizing computation resources. Besides, a MapReduce cloud is verified with popular applications in experiments to have the outstanding performance improvement with W ASF when intermediate data skew happens.
