title: Automatic Parallelisation of Web Applications

authors: Perrone, Gian David

subjects: computer science

abstract: Small web applications have a tendency to get bigger. Yet despite the current popularity of web applications, little has been done to help programmers to leverage the performance and scalability benefits that can result from the introduction of parallelism into a program. Accordingly, we present a technique for the automatic parallelisation of whole web applications, including persistent data storage mechanisms. We detail our prototype implementation of this technique, Ceth and finally, we establish the soundness of the process by which we extract coarse-grained parallelism from programs.

title: Geologically controlled sandy beaches: Their geomorphology, morphodynamics and classification

authors: Gallop, Shari L.

subjects: Science & Technology

abstract: Beaches that are geologically controlled by rock and coral formations are the rule, not the exception. This paper reviews the current understanding of geologically controlled beaches, bringing together a range of terminologies (including embayed beaches, shore platform beaches, relict beaches, and perched beaches, among others) and processes, with the aim of exploring the multiple ways in which geology influences beach morphology and morphodynamics. We show how in addition to sediment supply, the basement geology influences where beaches will form by providing accommodation, and in the cross-shore, aspects of rock platform morphology such as elevation and slope are also important. Geologically controlled beaches can have significant variations in sediment coverage with seasons and storms, and geological controls have fundamental influences on their contemporary morphodynamics. This includes wave shadowing by headlands and rock/coral formations inducing strong alongshore gradients in wave energy, resulting in corresponding variations in morphodynamic beach state and storm response. Geologically-induced rip currents including shadow rips, deflection rips and mega-rips that can develop on embayed beaches during storms, are an integral feature of the nearshore circulation and morphodynamics of geologically controlled beaches. We bring these processes together by presenting a conceptual model of alongshore and cross-shore levels of geological control. In the longshore dimension, this ranges from beaches that are slightly embayed, through to highly embayed beaches where headlands dominate the entire beach morphodynamic response. In the cross-shore dimension, this ranges from beaches without discernible geological controls, through to relict beaches above the influence of the contemporary littoral zone. Given the prevalence of geologically controlled beaches along the world's coasts, it is paramount for coastal management to consider how these beaches differ from unconstrained beaches and avoid applying inappropriate models and tools, especially with our uncertain future climate.

abstract: He rite tonu tā mātou hokihoki ki te take o Pirongia maunga, ki te tutungi i te ahi kā i Pūrekireki Marae. Ia wā ka hoki mātou ki tēnei o ngā marae, ka hīkaka taku ngākau, i te mea, ko taku mahi i reira, he tiaki ahi. Ao noa, pō noa, ko au te kaiwhakatutungi i te ahi o te kāuta, kei kewa. Ko te ahi o te kāuta o Pūrekireki marae, he ahi nui, he ahi kaitā. E ono tāngata pea ka uru ki te rua o te ahi nei. Nō reira, ko taku mahi i te rā, he kohi rākau i waho, he tapahi wahie, he whakamaroke anō hoki i te wahie, inā mākū i te ua. I ngā pō, kia hoki rā anō te iwi ki te moe, ko tāku, he noho ki roto i te kāuta me te tutungi ahi, kia wera tonu ai te wai mō āpōpō. Kei pōhēhē mai, he mahi mokemoke tēnei! Ehara! Ia pō, ka noho mai aku kuia ki taku taha ki te pahupahu. He nui ngā akoranga me ngā mātauranga i tuku iho mai ki a au i roto i tērā kāuta, i te taha o tērā ahi. Me uaua ka kitea tēnei momo ahi kaitā i ngā marae i ēnei rā. Kāore e whakaaengia ana e ngā ture Pākehā ngā ahi kaitā, pēnei nei te rahi, i roto i ngā kāuta o ngā marae; ‘Health and Safety Standards’ tā rātou i whakatau ai. Nō reira, i karangangia e taku pāpā tētehi hui ki te marae kia wānangahia te whakahōutanga o tō mātou kāuta. Nō taku rongotanga ake i te kaupapa o tēnei hui, ka tangi taku ngākau ki tō mātou kāuta. Nō reira, i whakarite ahau kia haere i tana taha.
