Being able to assess the scalability of Web and e-commerce sites is a challenge. The Transaction Processing Council (TPC) recently released a benchmark for e-commerce sites. This benchmark, called TPC-W, measures a system under test using Web Interactions per Second (WIPS) as its primary metric. This paper describes the benchmark's main features, the authors’ experience in building a TPC-W comp...

Background Eribulin is a microtubule dynamics inhibitor with a novel mechanism of action. This phase 3 study aimed to compare overall survival (OS) in patients with heavily pretreated non-small cell lung cancer (NSCLC) receiving eribulin to treatment of physician's choice (TPC). Patients and methods Patients with advanced NSCLC who had received ≥2 prior therapies, including platinum-based dou...

A method of determining the position readout sectors a time projection chamber using experimental data is proposed. Considering results modeling response sensitive elements multipurpose detector, three types tracks were reconstructed: cosmic muons, beams laser detector system, and muons from interaction nuclei. Employing experiment simulation proposed finding orientation chamber, accuracy align...

TPC benchmarks provide the de facto industry standard for measuring transaction processing performance. This paper argues that TPC-A and TPC-B have served their purpose and are effectively obsolete. Several problems with the benchmarks are described including flaws in the pricing model, the impact of terminals in the priceperformance metric, use of client-server configurations, and the use of s...

The TPC-D benchmark was developed almost 20 years ago, and even though its current existence as TPC-H could be considered superseded by TPC-DS, one can still learn from it. We focus on the technical level, summarizing the challenges posed by the TPC-H workload as we now understand them, which we call “choke points”. We identify 28 different such choke points, grouped into six categories: Aggreg...

Instructional technology can enhance the learning process for post secondary students. Colleges and universities have adopted computing initiatives that require every student to acquire their own portable computing device. Yet for such initiatives to improve students’ learning and teaching effectiveness, such technology-based initiatives must be accepted by students and faculty alike. This rese...

A random transmit power control (TPC) is applied to DSCDMA/TDD packet mobile radio, which controls the transmit power so as to intentionally vary the received signal power in order to obtain the large capture effect. The uplink capacity with the random TPC in a frequencyselective fading channel is evaluated by computer simulation. The simulation results show that the random TPC provides larger ...

Polysaccharide conjugates were alkali-extracted from green tea (TPC-A). Although it contained 11.80% covalently binding proteins, TPC-A could not bind to the Coomassie Brilliant Blue dyes G250 and R250. TPC-A had no expected characteristic absorption peak of protein in the UV-vis spectrum scanning in the range of 200-700 nm. The UV-vis wavelength of 280 nm was not suitable to detect the presenc...

The Transaction Processing Performance Council (TPC) is a nonprofit organization founded in 1988 to define transaction processing and database benchmarks. Since then, the TPC has played a crucial role in providing the industry with relevant standards for total system performance, price-performance, and energy-efficiency comparisons. TPC benchmarks are widely used by database researchers and aca...
