The Case for the Real Jesus: A Journalist Investigates Current Attacks on the Identity of Christ

Has sleek scholarship debunked the conventional Christ? Has the church suppressed the reality approximately Jesus to strengthen its personal schedule? What if the genuine Jesus is way varied from the atoning Savior worshipped throughout the centuries? within the Case for the genuine Jesus, former award-winning criminal editor Lee Strobel explores such hot-button questions as: * Did the church suppress historical non-biblical records that paint a extra exact photo of Jesus than the 4 Gospels?

Sample text

The four pole filters were found to provide a reasonable balance between the need for high frequency attenuation and small phase lag. If filters with a sharper cut-off were chosen, the resulting closed-loop system would have better high frequency suppression at the expense of greater phase lag. The increased phase lag within the feedback controller will degrade regulation. The aluminum plate had two odd modes 19 in the bandwidth of interest. The fundamental mode is around 300 Hz and the other around 1 KHz.

12) In Eq. 12), v is the disturbance model order and ξj (j = 1,2,…,v) are the AR disturbance model coefficients. In order to include the second to last term in Eq. 11), we need the future disturbance signal. This signal may be estimated by recursively solving for future values of the disturbance signal based on past disturbance measurements and Eq. 12). This recursive relationship is the same as that of Ref. [15]. Shown below in Eq. 13) is the jth prediction of the disturbance signal. 13) In Eq.

1 Introduction As shown in Chapter 3, predictive feedback control has been successfully used in the regulation of plate vibrations when no reference signal is available for feedforward control. However, if a reference signal is available it may be used to enhance regulation by incorporating a feedforward path in the feedback controller41. Such a controller is known as a feedback/feedforward controller. This chapter presents the theory and implementation of the feedback/feedforward controller to achieve vibration regulation.
