Abstract— Multi-electrode cuffs (MECs) have been proposed as a means for extracting additional information about the velocity and direction of nerve signals from multi-electrode recordings. This paper discusses certain aspects of the implementation of a system for velocity selective recording (VSR) where multiple neural signals are matched and summed to identify excited axon populations in terms of velocity. The approach outlined in the paper involves the replacement of the digital signal processing stages of a standard delay-matched VSR system with analogue switched-capacitor (SC) delay lines which promises significant savings in both size and power consumption. The system specifications are derived and two circuits, each composed of low-noise preamplifiers connecting to a 2 nd rank SC gain stage, are evaluated. One of the systems provides a single-ended SC stage whereas the other system is fully differential. Both approaches are shown to provide the low-noise, low-power operation, practically identical channel gains and sample delay range required for VSR. Measured results obtained from chips fabricated in 0.8 µm CMOS technology are reported.
7 Mobile Applications on Global Clouds Using Openflow and Software- Defined Networking

Introduction In recent years, there has been an explosive growth in mobile applications (apps), most of which need to serve global audiences. This increasing trend of service access from mobile computing devices necessitates more dynamic application deployment strategies. Cloud computing provides unique opportunities for these application service providers (ASPs) to manage and optimize their distributed computing resources. For this trend to be successful, similar facilities need to be developed for the on-demand optimization of connectivity resources to enhance user experience. Application delivery, on the surface, is simply connecting a user to a server. The original host-centric Internet architecture was well designed for this end-to-end two-host communication using source and destination IP addresses or names. However, today's Internet is mostly service centric, where users are interested in connecting to a service instead of a particular host. Delivering services over a host-centric design has led to complex application deployment environments , as discussed below, for the case of a single private data center (Figure 7.1), a single cloud environment, and a multicloud environment. Service Replication To scale a service, the service needs to be repli-cated over multiple servers. Network-layer load balancers were introduced into the network datapath to dynamically map the requests to the least loaded server. Pure control plane mechanisms, such as rotating domain name system (DNS), provide static load balancing. Service Partitioning To improve performance, services often need to be partitioned, and each partition is hosted on a separate server. Each partition may be further replicated over multiple servers. A service may be partitioned based on content and/or context. Content-Based Partitioning Even for the same service (e.g., xyz. com), accounting messages, recommendation requests, and video requests are all sent to different server groups. This can be done either by giving a different DNS name to each content type server or, as is common, by putting a proxy that classifies messages based on content.

Watermarking FPGA Bitfile for Intellectual Property Protection

Intellectual property protection (IPP) of hardware designs is the most important requirement for many Field Programmable Gate Array (FPGA) intellectual property (IP) vendors. Digital watermarking has become an innovative technology for IPP in recent years. Existing watermarking techniques have successfully embedded watermark into IP cores. However, many of these techniques share two specific weaknesses: 1) They have extra overhead, and are likely to degrade performance of design; 2) vulnerability to removing attacks. We propose a novel watermarking technique to watermark FPGA bitfile for addressing these weaknesses. Experimental results and analysis show that the proposed technique incurs zero overhead and it is robust against removing attacks.
ON THE STABILITY ANALYSIS OF WEIGHTED AVERAGE FINITE DIFFERENCE METHODS FOR FRACTIONAL WAVE EQUATION

In this article, a numerical study for the fractional wave equations is introduced by using a class of finite difference methods. These methods are extension of the weighted aver- age methods for ordinary (non-fractional) wave equations. The stability analysis of the proposed methods is given by a recently proposed procedure similar to the standard John von Neumann sta- bility analysis. Simple and accurate stability criterion valid for different discretization schemes of the fractional derivative, arbitrary weight factor, and arbitrary order of the fractional deriva- tive, is given and checked numerically. Numerical test example and comparisons have been presented for clarity.
De waarde van mbo-4 opleidingen op de arbeidsmarkt

De positie van de Nederlandse MBO-4 opleidingen ten opzichte van andere beroepsopleidingenin Nederland en ten opzichte van vergelijkbare beroepsopleidingen in hetbuitenland is niet helemaal duidelijk. Als we kijken naar de relatief lange cumulatieveopleidingsduur, dan zou dit opleidingstype ook tot het tertiare onderwijs gerekendkunnen worden. Voor de bepaling van de positie en plaats van de MBO-4 opleidingengaat het echter niet alleen om de cumulatieve opleidingsduur, maar ook omhet bereikte niveau van competenties. De vraag is dan of het niveau van competentiesvan MBO-4 opleidingen vergelijkbaar is met het niveau van competenties bij bijvoorbeeldde korte opleidingen in het hoger onderwijs.
Handbook of Research on Human Resources Strategies for the New Millennial Workforce

The dynamic nature of the management function in global business today and the realisation that what works effectively in one country may not be as efficient in another has led management scholars and practising managers in continuous efforts to enhance their understanding of this environment and its effects to managers. This chapter explores management across cultures. The discussion starts with the origin and definition of cross cultural management; then it is focused on the study of the international human resources management (IHRM). The final part discusses the profile of the international managers and the competencies needed to cope with the multiple challenges they are faced with in overseas assignments.
Mobile Robot Experimental Analysis Based on Kinematics

This article presents a new methodology for measuring amount of errors in wheeled robots. Here a four-wheeled robot is tested and corrected using a new benchmark method that called “YMB mark”. This manner treats the systematic errors during the structural design and based on kinematics equations. Because the effect of design process, type of modeling and robot controller on these errors, first the overall design is investigated. Thus the kinematics and dynamic equations of final design are derived in a symbolic form. In order to validate the derived equations, the consequences of simulation in Maple and Working Model softwares are carried out. Finally, the robot is moved in some trajectories for determining the systematic errors. Key-Words: Mobile robot, Modeling, Simulation, Odometry Test, YMB Mark Method
Grigni: [20]

The most challenging instances of computational problems are often found near a critical threshold in the problem's parameter space [1], where certain characteristics of the problem change dramatically. Monasson et al. [2] have conjectured a correlation between computational complexity and physical \phase transition" behavior at this threshold: computationally \hard" problems (running time exponential in problem size) display a discontinuous phase transition under an order parameter; computationally \easy" ones (polynomial in problem size) display a continuous phase transition. They showed that this holds for a class of problems called K-satis ability (K-SAT), which depending on the value of K can be either hard or easy. However, to argue convincingly for the existence of such a correlation, further evidence is needed. Here, we study two distinctly di erent graph-based problems, one hard and one easy, demonstrating numerically that in both cases the conjecture holds. A random graph [3] is constructed out of a set of N vertices by assigning an edge to each pair of vertices with probability p. The two problems we consider on the graph are 3-coloring and graph bi-partitioning. The goal of 3-coloring (3-COL) is to label each vertex with any one of three colors so as to minimize the number of edges connecting two vertices of the same color (the \cost"). If the average connectivity pN per vertex is very small, almost all vertices have fewer than 3 neighbors and a zero-cost coloring exists. But at our observed critical value (pN)crit 4:73 (see also Refs. [4, 1]), there is a sudden transition to a regime with almost no perfect colorings. For 3-COL, nding a zero-cost solution (if one exists) is NP-complete [5], and thus computationally hard in the worst case. In the graph bi-partitioning problem (GBP), the goal is to divide the N vertices into two sets of exactly equal size N=2 so as to minimize the number of edges connecting vertices in opposite sets (the \cost"). At low connectivity, the graph consists of many small disconnected clusters that are easily bi-partitioned, again at zero cost. At the critical value (pN)crit = 2 ln 2, a single giant cluster of size > N=2 emerges [6], making the cost positive. For the GBP, nding a zero-cost solution is computationally easy [5]. Unlike K-SAT, these graph problems exhibit a
THE MOST METAL-POOR STARS. I. DISCOVERY, DATA, AND ATMOSPHERIC PARAMETERS

We report the discovery of 34 stars in the Hamburg/ESO Survey for metal-poor stars and the Sloan Digital Sky Survey that have [Fe/H] ≲ −3.0. Their median and minimum abundances are [Fe/H] = −3.1 and −4.1, respectively, while 10 stars have [Fe/H] < −3.5. High-resolution, high signal-to-noise spectroscopic data—equivalent widths and radial velocities—are presented for these stars, together with an additional four objects previously reported or currently being investigated elsewhere. We have determined the atmospheric parameters, effective temperature (Teff), and surface gravity (log g), which are critical in the determination of the chemical abundances and the evolutionary status of these stars. Three techniques were used to derive these parameters. Spectrophotometric fits to model atmosphere fluxes were used to derive Teff, log g, and an estimate of E(B − V); Hα, Hβ, and Hγ profile fitting to model atmosphere results provided the second determination of Teff and log g; and finally, we used an empirical Teff-calibrated Hδ index, for the third, independent Teff determination. The three values of Teff are in good agreement, although the profile fitting may yield systematically cooler Teff values, by ∼100 K. This collective data set will be analyzed in future papers in the present series to utilize the most metal-poor stars as probes of conditions in the early universe.
In This Issue Stress Testing the Czech Banking System Martin Čihák (on Page 2) Estimating Credit Risk under Macroeconomic Fluctuations Bank Failures and Inefficient Cost Management

Central banks have been faced with many conceptual challenges in the course of ensuring financial system stability. The list of problems includes the ability to predict the likelihood and severity of financial crises, the optimum level of prudential capital requirements, and the early detection of the risk of individual bank failure. This issue of the Bulletin highlights the results of analyses of the Czech banking sector's ability to withstand various economic shocks (M. Čihák), the bank capital requirements generated by various approaches to risky debt evaluation (A. Derviz), and the extent and consequences of inefficient cost management in banks (A. Podpiera). This in-house economic research made a major contribution to the first Financial Stability Report published by the CNB in January 2005.

Ngc 2362: a Template for Early Stellar Evolution

We present UBVRI photometry for the young open cluster NGC 2362. From analysis of the appropriate color-color and color-magnitude diagrams we derive the fundamental parameters of the NGC 2362 cluster to be: age = 5 +1 −2 Myr, distance = 1480 pc, E(B − V) = 0.10 mag. The cluster age was independently determined for both high mass (2.1 − 36M ⊙) and low mass (0.7 − 1.2M ⊙) stars with excellent agreement between the ages derived using post-main sequence (Girardi et al. 2000) and pre-main sequence (Baraffe et al. 1998) evolutionary tracks for the high and low mass stars respectively. Analysis of this cluster's color-magnitude diagram reveals a well defined pre-main sequence (covering ∆ V ∼ 9 magnitudes in V and extending from early A stars to near the hydrogen burning limit) which makes this cluster an ideal laboratory for pre-main sequence evolution studies.
Morphologie und Bruchverhalten von Polyethylen/Polypropylen-Mischungen

Durch die Auswahl einer geeigneten Rezeptur werden hochzahe Polyethylen/Polypropylen- Mischungen mit Haftvermittlerzusatz entwickelt, deren Morphologie analysiert sowie die fur die hohe Kerbschlagzahigkeit verantwortlichen Deformations- und Bruchmechanismen erlautert. Im Vordergrund der Betrachtungen stehen dabei werkstoffseitige Einflussfaktoren auf das Zahigkeitsverhalten der PE/PP-Mischungen, wobei die Abhangigkeit vom Volumenanteil der einzelnen Komponenten, der Einfluss der Phasenmorphologie und der Beitrag der Phasenhaftung untersucht werden. Zum Einsatz kommen u.a. die Elektronenmikroskopie, mechanische und bruchmechanische Prufmethoden sowie die Schallemission. Durch die Zugabe eines Haftvermittlers werden feindisperse Morphologien und bessere Phasenhaftung in der Grenzschicht erzielt. Damit werden Zahigkeitsverbesserungen gegenuber den Homopolymeren um den Faktor 5 bis 8 erreicht.
Asymmetric Information And Overeducation

Abstract We consider an economy where production may use labor of two different skill levels. Workers are heterogeneous and, by investing in education, self-select into one of the two skills. Ex-ante, when firms choose their investments in physical capital, they do not know the level of human capital prevailing in the labor market they will be active in. We prove existence and constrained inefficiency of competitive equilibria, which are always characterized by overeducation. An increase in total expected surplus can be obtained by shrinking, at the margin, the set of workers investing in high skills. This can be implemented by imposing taxes on the cost of investing in high skills or by imposing a progressive labor earning tax.
Evolutionary Biology the Conditional Economics of Sexual Conflict

Sexual conflict is a fundamentally important aspect of male–female interactions. In this opinion piece, we emphasize two approaches that warrant significantly greater attention. First, we review the importance of understanding the 'economics' (costs and benefits) of sexual interactions and note surprisingly large, unrecognized gaps in our knowledge. Second, we highlight the novel obstacles and opportunities afforded by the dependence of sexually antagonistic (SA) selection on both the local environment and condition of the interacting individuals. We conclude that more research in these two areas is essential to fully understand the evolution of SA interactions and will provide significant new insights into the extent to which coevolution of the sexes is shaped by conflict. We argue that these approaches, although not new to the field, are undervalued and under-represented. 1. INTRODUCTION Sexual conflict is now widely recognized as an important component of male– female interactions. It creates a novel opportunity for selection, not captured by models of sexual selection, which can drive the coevo-lution of sexually antagonistic (SA) traits that can potentially result in opposing fitness effects in the two sexes (Arnqvist & Rowe 2005). In this opinion piece, we make two points about well known but under used approaches. First, we emphasize that economic studies have an essential role in assessing the extent of SA interactions and thus their potential to drive coevolution. Theory shows that the extent to which SA traits coevolve, and the extent to which population fitness declines as a result, depend crucially on the mating 'economy', i.e. the fitness costs and benefits of traits that mediate male–female interactions (Parker 1979; Rowe & Day 2006). There are now many examples in which sexual conflict is thought to drive the evolution of mating behaviour and morphology. However, there are surprisingly few systems in which the full economy of sexual traits has been assessed, including costs of producing and bearing traits, benefits of trait expression and costs and benefits of processing or resisting traits for the other sex. The lack of such data is notable because economic studies are needed (i) to infer the extent to which SA coevolution influences overall population
H∞ CONTROL OF SWITCHED LINEAR PARABOLIC SYSTEMS

The H∞ control problem of a class of switched linear parabolic systems is considered. By applying the multiple Lyapunov function method and the average dwell time scheme, sufficient conditions for exponential stability and the H∞ control synthesis are established in terms of LMIs and a family of switching signals. The advantage in this work lies in the fact that sufficient conditions completely depend on the system parameters and the system can be analyzed by using numerical softwares. At the end of the paper, an example is given to illustrate the obtained result.

This paper presents the post-processing techniques designed to improve the results of a speaker diarization system. Three different techniques are proposed: refinement of speech vs. non speech segmentation, assimilation of short speech segments and fusion of clusters from the same speaker. These techniques have been implemented in a post-processing module that improves the result of the baseline system by 22.3 %. The same module has been applied to another speaker diarization system with a similar architecture to that of the baseline system with a DER improvement of 21% and to another one with a very different architecture where no improvement has been achieved. It has also been used with another database with an improvement of 17 %. These experiments prove the validity of the techniques developed

Wire Bonding - A Closer Look

Just like soldering, wire bonding appears to be a simple process and is frequently taken for granted. People tend to think all that is required to have a high quality bonding process is a simple wire pull test to monitor and control the process. But like soldering, this process is complex and requires a thorough understanding of the metallurgy, thermodynamics, and surface chemistry involved. This paper will report on a study of the wire bonding which is representative of the semiconductor industry from the aspect of the materials involved, the metallurgy of the resultant bonds, and techniques of monitoring the bond quality. It will also present information on the ability of a bond to withstand various aging conditions and the most effective manner to monitor bond quality.
Lean supply chain performance evaluation method

Increasing global competitiveness worldwide has forced manufacturing organizations to produce high-quality products more quickly and at a competitive cost which demand of continuous improvements techniques. In this paper, we propose a fuzzy based performance evaluation method for lean supply chain. To understand the overall performance of cost competitive supply chain, we investigate the alignment of market strategy and position of the supply chain. Competitive strategies can be achieved by using a different weight calculation for different supply chain situations. By identifying optimal performance metrics and applying performance evaluation methods, managers can predict the overall supply chain performance under lean strategy.
