This paper summarizes the idea of Adaptive-Latency DRAM (AL-DRAM), which was published in HPCA 2015 [64]. The key goal of AL-DRAM is to exploit the extra margin that is built into the DRAM timing parameters to reduce DRAM latency. The key observation is that the timing parameters are dictated by the worst-case temperatures and worst-case DRAM cells, both of which lead to small amount of charge ...

Power enhancement technologies for gas turbines such as inlet fogging, interstage water injection, saturation cooling, inlet chillers, and combustor injection are being used by end users without evaluating the potentially negative effects these devices may have on the operational integrity of the gas turbine. Specifically, the effect of these add-on devices, off-design operating conditions, non...

The Medicare prospective payment system (PPS) contains incentives for hospitals to improve efficiency by placing them at financial risk to earn a positive margin on services rendered to Medicare patients. Concerns about the financial viability of small rural hospitals led to the implementation of the Medicare Rural Hospital Flexibility Program (Flex Program) of 1997, which allows facilities des...

PURPOSE To evaluate the influence of prior abdominal surgery on the outcomes after robotic-assisted laparoscopic radical prostatectomy (RALP). MATERIALS AND METHODS We retrospectively analyzed patients with prostate cancer who underwent RALP between June 2012 and February 2015 at our institution. Patients with prior abdominal surgery were compared with those without prior surgery while consid...

BACKGROUND During the 1990's hospitals in the U.S were faced with cost containment charges, which may have disproportionately impacted hospitals that serve poor patients. The purposes of this paper are to study the impact of safety net activities on total profit margins and operating expenditures, and to trace these relationships over the 1990s for all U.S urban hospitals, controlling for hospi...

Axial flow compressors are subjected to demands for ever-increasing levels of pressure ratio at a compression efficiency that augments the overall cycle efficiency. However, unstable flow may develop in the compressor, which can lead to a stall or surge and subsequently to gas turbine failure resulting in significant downtime and cost to repair. To protect against these potential aerodynamic in...

The concept of safety margins has served as a fundamental principle in the design and operation of commercial nuclear power plants (NPPs). Defined as the minimum distance between a system’s “loading” and its “capacity”, plant design and operation is predicated on ensuring an adequate safety margin for safety-significant parameters (e.g., fuel cladding temperature, containment pressure, etc.) is...

This study aims to determine the effect of return on assets (ROA), equity (ROE), net profit margin (NPM), earning per share (EPS) and operating (OPM) stock prices banking companies Indonesia Stock Exchange. type research is associative research. Secondary data in this form financial statements. The total population used were 32 companies, samples that met criteria eight listed BEI. analytical m...

stock return is usually considered to be affected by firm’s financial ratios as well as economic variables. fundamental method assume that stock returns is not solely related to the stock market. most result come from the company condition , industry situation and whole economy. in this paper, this relationship between stock return and fundamentals is studied using the data for 22 pharmaceutica...

OBJECTIVE To correlate microscopic margin status with survival and local control in a large cohort of patients from a high-volume pancreatic cancer center. DESIGN Retrospective database review. A uniform procedure for margin analysis was used with 4-color inking (neck, portal vein groove, uncinate, and posterior pancreatic margin) by the surgeon in the operating room. SETTING A tertiary car...
