Ammonia emissions from combustion in gasoline engines by Bajwa, A, Shankar, V, Leach, F

“…Forthcoming worldwide emissions regulations will start regulating ammonia emissions from light duty vehicles. At present, most light duty vehicles are powered by gasoline spark ignition engines. …”

On commodifying what is irreplaceable by Mortimer, S

“…In particular, I argue that when a company’s stakeholders value something as irreplaceable, the company has a duty to avoid violating it (such as by destroying or damaging it, otherwise altering it, or withholding it from stakeholders, depending on what it is about the entity that the stakeholders value as irreplaceable).…”

An improved programmable grating array based wavefront sensor by Pathak, B

“…An improved programmable grating array based wavefront sensor (GAWS) is proposed which is capable of estimating the incident wavefront more accurately, by generating an array of uniform intensity +1 order spots with negligible contribution from unwanted higher order spots. The duty cycle of each grating element of the proposed sensor is effectively varied in order to independently control the intensity of each +1 order spot. …”

On the spin-up of neutron stars to millisecond pulsars in long-period binaries by Ritter, H, King, A

“…Using a-disc models and taking into account the effect of irradiation of the accretion disc by the central accretion light source we derive explicit expressions for the duty cycle d and the accretion efficiency 77 in terms of the parameters of the binary system and the disc instability limit cycle. …”

Discrete Gene Regulatory Networks (dGRNs): A novel approach to configuring sensor networks by Markham, A, Trigoni, N

“…The operation of a sensor network is determined by a large number of parameters, such as the radio duty cycle, the frequency of neighbor discovery beacons, and the rate of sampling sensors. …”

Electrochemical cell balancing using a full-bridge multilevel converter and pseudo-open circuit voltage measurements by Chatzinikolaou, E

Real-time passive acoustic monitoring of tissue damage during thermal ablation by high-intensity focused ultrasound. by Nandlall, S, Jackson, E, Coussios, C

“…A total of 161 exposures were performed in seven freshly excised ox livers using 1.067-MHz HIFU at a 95% duty cycle. Acoustic emissions were recorded using a 15-MHz passive detector aligned confocally and coaxially with the HIFU transducer. …”

Thermal analysis of steel and aluminium pistons for an HSDI Diesel engine by Papaioannou, N, Leach, F, Davy, M

“…Chromium-molybdenum alloy steel pistons, which have been used in commercial vehicle applications for some time, have more recently been proposed as a means of improving thermal efficiency in light-duty applications. This work reports a comparison of the effects of geometrically similar aluminium and steel pistons on the combustion characteristics and energy flows on a single cylinder highspeed direct injection diesel research engine tested at two speed / load conditions (1500 rpm / 6.9 bar nIMEP and 2000 rpm/25.8 bar nIMEP) both with and without EGR. …”

Rethinking home network security by Nthala, N, Flechais, I

“…We found evidence that current security practices in the home are focussed on securing endpoints; home users assess risk by evaluating the impact of a successful attack, and also the value of gain for the attacker; identification of security problems in the home is done through visibility of harm, security alerts and warnings, and intuition; incident management in the home is mostly done through social networks and often undertaken by trusted individuals as an informal duty of care. We discuss these findings and provide recommendations for improving network security in the home.…”

Exploitation of cavitation-enhanced heating for release of doxorubicin from thermosensitve liposomes by therapeutic ultrasound. by Mylonopoulou, E, Bazan-Peregrino, M, Arvanitis, C, Coussios, C
