Fracture behavior of CPM 10V
… behavior of a commercial powder metal alloy, CPM 10V, was investigated. Fracture toughness was increased by increasing the tempering temperatures and decreased by increasing the austenitizing temperature. These changes were related to changes in yield strength and the resulting crack tip …

A PAM Decomposition of Weak CPM
The Enhanced Flight Termination System uses weak CPM as its modulation scheme and a limiter-discriminator as its demodulation scheme. A PAM representation of weak CPM was developed which representation provided the necessary componenents to build a simplified PAM-based receiver that outperformed …

CPM Equalization to Compensate for ISI due to Band Limiting Channels
… power has made Continuous Phase Modulation (CPM) one of the most attractive modulation schemes in band limited channels. However, as the data rates keep increasing, the spectral width of the CPM signal increases beyond the channel bandwidth and performance becomes constrained by the …

A Resource-constrained CPM (RCPM) Scheduling and Control Technique with Multiple Calendars
… a Resource-constrained Critical Path Method (RCPM) technique that capitalizes on and improves the existing Critical Path Method (CPM) and Resource-Constrained Scheduling (RCS) techniques. A traditional CPM schedule is not realistic since it assumes unlimited resources, some of which are highly …

Computer Monitoring in the Workplace: Performance Effects and Perceptions
<p>Computer performance monitoring (CPM) has become prevalent in modern day as several work functions are now completed on the computer. Under the framework of social facilitation effect (Zajonc, 1965), it is possible that CPM may affect performance because of the feeling of being evaluated. In …

Choosing Mastectomy: A Qualitative Exploration of the Increasing Mastectomy Rates in Women with Early-stage Breast Cancer
… (UM) and contralateral prophylactic mastectomy (CPM) for early-stage breast cancer (ESBC) have been increasing. Numerous factors for this rise have been suggested including the surgeon's preference, the patient's choice and the external environment. Objectives: A grounded theory study explored …

Reduced Complexity Detection Methods for Continuous Phase Modulation
Continuous phase modulation (CPM) is often plagued by high receiver complexity. One successful method of dealing with this is the well-known pulse amplitude modulation (PAM) representation of CPM, which was first proposed by Laurent. It is shown that the PAM representation also applies to multi-h …

An Investigation of the Expanding Role of the Critical Path Method by ENR'S Top 400 Contractors
The Critical Path Method (CPM) is a widely used tool throughout the construction industry. Since its creation, the use and application of the Critical Path Method has grown tremendously. Up to date, three studies have been performed on how Engineering News Record's (ENR) Top 400 Contractor use CPM. …
