Weighted GCV Method Sample Clauses

Weighted GCV Method. In this section we describe a modification of the GCV function, called weighted- GCV (W-GCV), that improves our ability to choose regularization parame- ters for the projected problem. We first describe the approach for Tikhonov regularization for a general linear system of equations. Then in Section 2.4.3 we show how to apply it to the projected problem.

These plots show the relative error, ǁxk − x trueǁ2/ǁx trueǁ2, at each iteration of LSQR and the Lanczos-hybrid method for the Satellite example. The top left plot provides results after full reorthogonalization of the Lanczos vectors, and the top right plot provides results after using TSVD filtering, rather than Tikhonov. The bottom plots show the results from delayed regularization of the projected problem.

  • Measurement method An isolation resistance test instrument is connected between the live parts and the electrical chassis. The isolation resistance is subsequently measured by applying a DC voltage at least half of the working voltage of the high voltage bus. If the system has several voltage ranges (e.g. because of boost converter) in conductively connected circuit and some of the components cannot withstand the working voltage of the entire circuit, the isolation resistance between those components and the electrical chassis can be measured separately by applying at least half of their own working voltage with those components disconnected.

  • Billing Method 1.5.1 To receive payment for services rendered under this contract, the Contractor shall submit a fully completed invoice for work previously performed to: Minneapolis Public Housing Authority Attention: Accounts Payable, Suite 307 0000 Xxxxxxxxxx Xxx X, Xxxxxxxxxxx, XX 00000 or: xxxxxxxx@xxxxxxx.xxx

  • Test method 3.3.1. The method used shall be that described in Annex 3, paragraph 3.1.

  • Calculation methodology No adjustment in the Conversion Price need be made unless the adjustment would require an increase or decrease of at least 1% in the Conversion Price then in effect, provided that any adjustment that would otherwise be required to be made shall be carried forward and taken into account in any subsequent adjustment. Except as stated in this Article VI, the Conversion Rate will not be adjusted for the issuance of Common Stock or any securities convertible into or exchangeable for Common Stock or carrying the right to purchase any of the foregoing. Any adjustments that are made shall be carried forward and taken into account in any subsequent adjustment. All calculations under Article V and Section 6.06 hereof and this Section 6.07 shall be made to the nearest cent or to the nearest 1/10,000th of a share, as the case may be.

  • Voting Method Unless otherwise provided by law, when a vote is taken upon any measure before the Board, with a quorum being present, a majority of the votes cast shall determine its outcome. A vote of "abstain" or "present," or a vote other than "yea" or "nay," or a failure to vote, is counted for the purposes of determining whether a quorum is present. A vote of "abstain" or "present," or a vote other than "yea" or "nay," or a failure to vote, however, is not counted in determining whether a measure has been passed by the Board, unless otherwise stated in law. The sequence for casting votes is rotated. On all questions involving the expenditure of money and on all questions involving the closing of a meeting to the public, a roll call vote shall be taken and entered in the Board's minutes. An individual Board member may request that a roll call vote be taken on any other matter; the President or other presiding officer may approve or deny the request but a denial is subject to being overturned by a majority vote of the members present. Any Board member may request that his or her vote be changed before the President announces the result. Any Board member may include a written explanation of his or her vote in the District file containing individual Board member statements; the explanation will not be part of the minutes. Minutes The Board Secretary shall keep written minutes of all Board meetings (whether open or closed), which shall be signed by the President and the Secretary. The minutes include:

  • ICE Method The method used to calculate One-Month LIBOR, as described in Section 3.05.

  • Mileage Measurement Where required, the mileage measurement for LIS rate elements is determined in the same manner as the mileage measurement for V&H methodology as outlined in NECA Tariff No. 4.

  • Balance Computation Method For all dividend-bearing Accounts, dividends are calculated by the average daily balance method which applies a daily periodic rate to the average daily balance for the average daily balance calculation period. The average daily balance is determined by adding the full amount of the principal in Your Account for each day of the period and dividing that figure by the number of days in the period. Accrual on Noncash Deposits. For dividend-bearing Accounts, dividends will begin to accrue on the business day that You deposit noncash items (e.g. checks) into Your Account.

  • Usage Measurement Usage measurement for calls shall begin when answer supervision or equivalent Signaling System 7 (SS7) message is received from the terminating office and shall end at the time of call disconnect by the calling or called subscriber, whichever occurs first.

  • Supported wage rates Employees to whom this clause applies shall be paid the applicable percentage of the minimum rate of pay prescribed by this Agreement for the class of work which the person is performing according to the following schedule: Assessed Capacity (Clause 1.3) % of prescribed rate 10%* 10% 20% 20% 30% 30% 40% 40% 50% 50% 60% 60% 70% 70% 80% 80% 90% 90% * (Provided that the minimum amount payable shall be not less than $45 per week). Where a person’s assessed capacity is 10%, they shall receive a high degree of assistance and support.
