Stretch: Balancing QoS and Throughput for Colocated Server Workloads on SMT Cores

Boris Robert Grot, Siddharth Gupta

In a drive to maximize resource utilization, today's datacenters are moving to colocation of latency-sensitive and batch workloads on the same server. State-of-the-art deployments, such as those at Google, colocate such diverse workloads even on a single S ...

Restoring Jean Prouvé. The “Buvette” at Evian and other technical objects

Giulia Marino

Completed in 1957, the new buvette (pump room) of the Source Cachat in Evian-les-Bains is to be classed among twentieth-century icons. The building was the outcome of a fruitful partnership be-tween an experienced architect, Maurice Novarina, an “inspired ...

Non-setting, injectable biomaterials containing particulate hydroxyapatite can increase primary stability of bone screws in cancellous bone

Dominique Pioletti, Ulrike Kettenberger, Jorge Solana Munoz

BACKGROUND: Fracture fixation in weak bone is still a clinical challenge. Screw augmentation was shown to successfully increase their primary stability. The currently used calcium phosphate or polymeric bone cements, however, present important drawbacks su ...

Failure of mounting bolt of helicopter main gearbox support strut

Predrag Andric

The mounting bolt of helicopter main gearbox support strut was fractured into two pieces during the flight mission. The fracture occurred at the root of the first engaged thread of the bolt-nut assembly. Visual inspection of the fracture zone revealed crac ...

Variability of the pullout strength of cancellous bone screws with cement augmentation

Dominique Pioletti

Background: orthopaedic surgeons often face clinical situations where improved screw holding power in cancellous bone is needed. Injectable calcium phosphate cements are one option to enhance fixation. Methods: paired screw pullout tests were undertaken in ...

Adjustable fixation system for neurosurgical devices

Jean-Philippe Thiran, Rémi Charrier, David Haag

The system comprises at least a support (5) to be attached to a patient by fixing means (4), said support having an outer thread (7), a first nut (9) with an inner thread (11 ) cooperating with said outer thread (7) and an anchor having a spherical bottom ...

Injectable calcium phosphate cement for augmentation around cancellous bone screws. In vivo biomechanical studies

Dominique Pioletti, Vincent Stadelmann

In lower cancellous apparent bone density, it can be difficult to achieve adequate screw fixation and hence stable fracture fixation. Different strategies have been proposed, one of them is through augmentation using calcium phosphate cement in the region ...

Tightening force and torque of nonlocking screws in a reverse shoulder prosthesis

Dominique Pioletti, Alexandre Terrier, Alain Farron, Francesco Merlini, Miguel Gortchacow, Stephanie Kochbeck

Background. Reversed shoulder arthroplasty is an accepted treatment for glenohumeral arthritis associated to rotator cuff deficiency. For most reversed shoulder prostheses, the baseplate of the glenoid component is uncemented and its primary stability is p ...

Data-Oriented Transaction Execution

Anastasia Ailamaki, Frederick Ryan Johnson, Ippokratis Pandis

While hardware technology has undergone major advancements over the past decade, transaction processing systems have remained largely unchanged. The number of cores on a chip grows exponentially, following Moore's Law, allowing for an ever-increasing numbe ...

Scala actors: Unifying thread-based and event-based programming

Martin Odersky, Philipp Haller

There is an impedance mismatch between message-passing concurrency and virtual machines, such as the JVM. VMs usually map their threads to heavyweight OS processes. Without a lightweight process abstraction, users are often forced to write parts of concurr ...
