sodium salt of n-acetyl-dl-tryptophan (at) and octanoic acid (caprylic acid ca) individually and in combination were studied as thermal stabilizer with different concentrations in heat treatment of human albumin solution. hplc protein profiles before pasteurization of albumin showed less than 1% polymer. in free stabilizer albumin solution during pasteurization visible clot was formed. but by u...

PURPOSE Ankle joint dorsiflexion contributes to energy absorption during landing, but wearing ankle stabilizers is known to restrict passive measures of dorsiflexion. This study compared the effects of various ankle stabilizers on ankle joint kinematics during soft and stiff landings. METHODS Subjects (N = 14) performed two-legged landings off a 0.59-m platform. Kinematics of the right ankle ...

This paper presents an approach for the design of fuzzy logic power system stabilizers using genetic algorithms. In the proposed fuzzy expert system, speed deviation and its derivative have been selected as fuzzy inputs. In this approach the parameters of the fuzzy logic controllers have been tuned using genetic algorithm. Incorporation of GA in the design of fuzzy logic power system stabilizer...

Using combinatorial arguments, we determine an upper bound on achievable rates of stabilizer codes used over the quantum erasure channel. This allows us to recover the nocloning bound on the capacity of the quantum erasure channel, R ≤ 1− 2p, for stabilizer codes: we also derive an improved upper bound of the form R ≤ 1 − 2p − D(p) with a function D(p) that stays positive for 0 < p < 1/2 and fo...

A current source converter (CSC) based static synchronous compensator (STATCOM) is a shunt flexible AC transmission system (FACTS) device, which has a vital role in stability support for transient instability and damping support for undesirable interarea oscillations in an interconnected power network. A robust pole-shifting based controller for CSC-STATCOM with damping stabilizer is proposed. ...

Magic state distillation (MSD) is a purification protocol that plays a central role in fault tolerant quantum computation. Repeated iteration of the steps of a MSD protocol generates pure single non-stabilizer states, or magic states, from multiple copies of a mixed resource state using stabilizer operations only. Thus mixed resource states promote the stabilizer operations to full universality...

We report progress on the LU-LC conjecture—an open problem in the context of entanglement in stabilizer states (or graph states). This conjecture states that every two stabilizer states which are related by a local unitary operation , must also be related by a local operation within the Clifford group. The contribution of this paper is a reduction of the LU-LC conjecture to a simpler problem—wh...

Power system stabilizers (PSS) are now regularly used in the industry to damp out power system oscillations. High performance excitation system have become very important as limited generation capacity and consumer desires for power continue to increase. In this work, enhanced Artificial Bee Colony (ABC) technique is applied to design a robust power system stabilizer (PSS) in order to improve t...

Inadequate hole cleaning can lead to many problems in horizontal and directional wells. In this work, we tried to investigate the cutting transport phenomenon by an experimental directional drilling simulator, considering the differences between the operational and experimental conditions. The inclination, fluid type (water, foam, viscous, and dense), rotary speed (0 and 110 rpm), nozzle bit si...
