ROHDE & SCHWARZ NAP-Z3 Datasheet Test Equipment Solutions Datasheet Test Equipment Solutions Ltd specialise in the second user sale, rental and distribution of quality test & measurement (T&M) equipment. We stock all major equipment types such as spectrum analyzers, signal generators, oscilloscopes, power meters, logic analysers etc from all the major suppliers such as Agilent, Tektronix, Anritsu and Rohde & Schwarz. We are focused at the professional end of the marketplace, primarily working with customers for whom high performance, quality and service are key, whilst realising the cost savings that second user equipment offers. As such, we fully test & refurbish equipment in our in-house, traceable Lab. Items are supplied with manuals, accessories and typically a full no-quibble 1 year warranty. Our staff have extensive backgrounds in T&M, totalling over 150 years of combined experience, which enables us to deliver industry-leading service and support. We endeavour to be customer focused in every way right down to the detail, such as offering free delivery on sales, presenting flexible technical + commercial solutions and supplying a loan unit during warranty repair, if available. As well as the headline benefit of cost saving, second user offers shorter lead times, higher reliability and multivendor solutions. Rental, of course, is ideal for shorter term needs and offers fast delivery, flexibility, try-before-you-buy, zero capital expenditure, lower risk and off balance sheet accounting. Both second user and rental improve the key business measure of Return On Capital Employed. We are based at Aldermaston in the UK from where we supply test equipment worldwide.

Arasu Department of Mathematics & Statistics Wright State University 3640 Colonel Glenn Highway, Dayton, OH 45435 U.S.A. Jeffrey R. Hollon Department of Mathematics Sinclair Community College 444 W 3rd Street, Dayton, OH 45402 U.S.A. Abstract A weighing matrix is a square matrix whose entries are 1, 0 or −1,such that the matrix times its transpose is some integer multiple of the identity matrix. We examine the case where these matrices are said to be devel- oped by an abelian group. Through a combination of extending previous results and by giving explicit constructions we will answer the question of existence for 318 such matrices of order and weight both below 100. At the end, we are left with 98 open cases out of a possible 1,022. Further, some of the new results provide insight into the existence of matrices with larger weights and orders. 1 Introduction 1.1 Group Developed Weighing Matrices A weighing matrix W = W (n, k) is a square matrix, of order n, whose entries are in t the set wi,j ∈{−1, 0, +1}. This matrix satisfies WW = kIn, where t denotes the matrix transpose, k is a positive integer known as the weight, and In is the identity matrix of size n. Definition 1.1.

Computer Simulation of an Unsprung Vehicle, Part I Abstract The mechanics of unsprung wheel tractors has received extensive study in the last 40 years. The quantitative approach to the problem essentially began with the work of McKibben (7) in the 1920s. Twenty years later, Worthington (12) analyzed the effect of pneumatic tires on tractor stabiIity. Later, Buchele (3) drew on land- locomotion theory to introduce soil variables into the equations for tractor stability. Differential equations were avoided in these analyses by assuming that the tractor moved with zero or constant acceleration. Thus, vibration and actual tipping of the tractor were beyond the scope of the analyses.

  • Design and Analysis of Computer Experiments for Screening Input Variables Dissertation Presented in Partial Fulfillment of the R
    Design and Analysis of Computer Experiments for Screening Input Variables Dissertation Presented in Partial Fulfillment of the Requirements for the Degree Doctor of Philosophy in the Graduate School of The Ohio State University By Hyejung Moon, M.S. Graduate Program in Statistics The Ohio State University 2010 Dissertation Committee: Thomas J. Santner, Co-Adviser Angela M. Dean, Co-Adviser William I. Notz ⃝c Copyright by Hyejung Moon 2010 ABSTRACT A computer model is a computer code that implements a mathematical model of a physical process. A computer code is often complicated and can involve a large number of inputs, so it may take hours or days to produce a single response. Screening to determine the most active inputs is critical for reducing the number of future code runs required to understand the detailed input-output relationship, since the computer model is typically complex and the exact functional form of the input- output relationship is unknown. This dissertation proposes a new screening method that identifies active inputs in a computer experiment setting. It describes a Bayesian computation of sensitivity indices as screening measures. It provides algorithms for generating desirable designs for successful screening. The proposed screening method is called GSinCE (Group Screening in Computer Experiments). The GSinCE procedure is based on a two-stage group screening ap- proach, in which groups of inputs are investigated in the first stage and then inputs within only those groups identified as active at the first stage are investigated indi- vidually at the second stage. Two-stage designs with desirable properties are con- structed to implement the procedure.

  • RF Engineering Basic Concepts: S-Parameters
    RF engineering basic concepts: Sparameters F. Caspers CERN, Geneva, Switzerland Abstract The concept of describing RF circuits in terms of waves is discussed and the S-matrix and related matrices are defined. The signal flow graph (SFG) is introduced as a graphical means to visualize how waves propagate in an RF network. The properties of the most relevant passive RF devices (hybrids, couplers, nonreciprocal elements, etc.) are delineated and the corresponding S-parameters are given. For microwave integrated circuits (MICs) planar transmission lines such as the microstrip line have become very important. 1 S-parameters The abbreviation S has been derived from the word scattering. For high frequencies, it is convenient to describe a given network in terms of waves rather than voltages or currents. This permits an easier definition of reference planes. For practical reasons, the description in terms of in- and outgoing waves has been introduced. Now, a 4-pole network becomes a 2-port and a 2n-pole becomes an n- port. In the case of an odd pole number (e.g., 3pole), a common reference point may be chosen, attributing one pole equally to two ports. Then a 3-pole is converted into a (3+1) pole corresponding to a 2port. As a general conversion rule, for an odd pole number one more pole is added. I1 I2 Fig. 1: Example for a 2-port network: a series impedance Z Let us start by considering a simple 2-port network consisting of a single impedance Z connected in series (Fig. 1). The generator and load impedances are ZG and ZL, respectively.
