An overview of the ATLAS High Level Trigger Dataflow and Supervision.
No full textThe ATLAS high-level trigger (HLT) system provides software-based event selection after the initial LVL1 hardware trigger. It is composed of two stages, the LVL2 trigger and the event filter (EF). The LVL2 trigger performs event selection with optimized algorithms using selected data guided by Region of Interest pointers provided by the LVL1 trigger. Those events selected by LVL2 are built into complete events, which are passed to the EF for a further stage of event selection and classification using off-line algorithms. Events surviving the EF selection are passed for off-line storage. The two stages of HLT are implemented on processor farms. The concept of distributing the selection process between LVL2 and EF is a key element in the architecture, which allows it to be flexible to changes (luminosity, detector knowledge, background conditions, etc.) Although there are some differences in the requirements between these subsystems there are many commonalities. An overview of the dataflow (event selection) and supervision (control, configuration, monitoring) activities in the HLT is given, highlighting where commonalities between the two subsystems can be exploited and indicating where requirements dictate that implementations differ. An HLT prototype system has been built at CERN. Functional testing is being carried out in order to validate the HLT architecture
FACTORS INFLUENCING FARMERS' SELECTION OF A MILK HANDLER
No full textA structural probit model is estimated to determine the change in the probability of selecting a milk handler. Cooperatives are thought to have lower prices and higher deductions than independent milk handlers and these factors reduce the probability that a farmer will select a cooperative by 0.39 and 0.32. Cooperatives are thought to have better services and an assured market and payment than independent mile handlers and these factors increase the probability that a farmer will select a cooperative by 0.20 and 0.26. This indicates that many cooperative members value monetary characteristics over non-monetary characteristics.Cooperatives, Processors, Attributes, Selection, Probit, Dairy, Livestock Production/Industries,

RSX handler for transferring large blocks of data between tasks
No full textA pseudo-device handler was written which allows the transfer of up to 64K byte blocks of data between tasks. The basic mechanism is as follows: one task issues a read QIO which references another task to which the data are to be sent. This second task issues a write QIO referencing the first task. The handler resolves the two QIO's may be issued in any sequence and with any separation in time. Such a handler is useful in an environment in which it is important to conserve active page registers and virtual address space
A Qualidade do tratamento durante a lactação influencia o comportamento pós-desmame de leitões
No full textDissertação (mestrado) - Universidade Federal de Santa Catarina, Centro de Ciências Agrárias, Programa de Pós-Graduação em Agroecossistemas, Florianópolis, 2011Os objetivos deste estudo foram comparar o comportamento pósdesmame de leitões tratados de forma racional ou aversiva durante o período de lactação; e detectar se estes animais seriam capazes de reconhecer seu tratador habitual. Para isso, 24 porcas e suas leitegadas foram alojadas em salas diferentes, onde cada uma recebeu um tipo de tratamento. Uma pessoa do sexo feminino (P1) foi responsável pela alimentação dos animais e limpeza dos ambientes entre os dias 10-27 após o nascimento dos leitões. Neste período, para o tratamento aversivo (Aver), P1 gritava com frequencia, movia-se bruscamente e de forma imprevisível. Para o tratamento racional (Rac), P1 usava um tom de voz suave apenas quando necessário e movia-se cuidadosamente. No 28º dia os leitões foram desmamados e a resposta dos animais em relação à aproximação do tratador conhecido e de uma pessoa desconhecida num ambiente novo foi avaliada em 4 leitões de cada leitegada. Os escores variaram de 1 (experimentador poderia tocar leitão) a 4 (leitão escapava logo que a pessoa se movesse). O teste foi repetido duas vezes com cada animal, com um intervalo de 1 h, onde P1 vestia calça azul e camiseta branca, e o tratador desconhecido aos leitões (P2) vestia macacão azul. Depois disso, leitões de diferentes leitegadas mas que receberam o mesmo tipo de tratamento durante a fase de lactação foram misturados e mantidos em salas separadas de acordo com o tratamento, equilibrado por sexo e peso vivo (n=12 grupos de quatro leitões/tratamento). O comportamento foi observado através de instantâneos a cada 2 minutos, por 4 h por dia, durante 4 dias. Os escores de aproximação humana foram maiores para leitões de Aver do que para Rac quando testado com P1 (P = 0,04), mas não com P2 (P = 0,8). Frequências de #repouso# foi menor (P 0,05). Conclui-se que leitões com 4 semanas de idade podem discriminar um tratador de acordo com a natureza do tratamento recebido durante a lactação. Além disso, os leitões tratados aversivamente demonstram maior inquietação ao desmame.The aim of this study was to compare the post-weaning behaviour in the first four days of piglets treated either rational or aversively during the suckling period and identify whether these animals would be able to recognize his usual handler. For this, 24 sows and their litters were housed in different rooms according to treatment. A female experimenter (P1) was in charge of feeding and cleaning from days 10 to 27 after birth. During this period, for the aversive treatment (Aver), P1 moved harshly and unpredictably and shouted frequently during routine cleaning of facilities and animal handling. For the rational treatment (Rac), P1 used a soft tone of voice and was careful during the same routine. At 28 days, piglets were weaned and the avoidance response of piglets to an approaching experimenter in a novel place was assessed in four piglets from each litter. Scores ranged from 1 (experimenter could touch piglet) to 4 (piglet escaped as soon as person moved). The test was repeated twice, with a 1-h interval, with P1, who wore blue trousers and white T-shirt, and a second handler unfamiliar to the piglets (P2, who wore blue coveralls). Thereafter, piglets from different litters but that received the same treatment during the lactation were mixed and housed in separate rooms, balanced for gender and live weight (n=12 groups of 4 piglets/treatment). Behaviour time budgets were registered by scan sampling every 2-min, for 4 h per day, for 4 days. Avoidance score was higher for Aver than Rac piglets when tested with P1 (P=0.04) but not with P2 (P=0.8). Frequencies of resting were lower (P<0.001), whereas escape attempts (P<0.03), agonistic interactions (P<0.02) and frequency of presence at feeder (P<0.001) were higher in the Aver than in the Rac groups. Feed and water intake and weight gain did not differ between treatments. It is concluded that 4- week-old piglets can discriminate a handler according to the nature of treatment received during suckling. In addition, piglets treated aversively seem to have more difficulty adapting to weaning than those treated neutrally during the suckling period
Sequencing Wafer Handler Moves to Improve the Performance of Hybrid Cluster Tools
No full textCluster tools are highly integrated machines that can perform a sequence of semiconductor manufacturing processes. The sequence of wafer handler moves affects the total time needed to process a set of wafers. Reducing this time can reduce cycle time, reduce tool utilization, and increase tool capacity. This paper introduces the cluster tool scheduling problem for hybrid cluster tools, which are multiple-stage tools that have at least one stage with two or more parallel chambers. This paper presents algorithms that can find superior sequences of wafer handler moves. Experimental results show that the tool performance can be improved significantly if the wafer handler follows a cyclic sequence instead of using a dispatching rule

Effect Handler Oriented Programming for Data Processing Applications
No full textEffect handler oriented programming or EHOP for short, is a new programming paradigm aiming to achieve separation of concerns in code which will lead to modular, readable and maintainable code. Since EHOP is significantly new, it is important to assess and compare it against traditional, commonly used paradigms in order to see if a wider adoption of EHOP would prove beneficial to computer science. In this research, EHOP was compared with traditional paradigms under the context of data processing applications. An Excel-like command line application called “MiniExcel” was implemented from scratch. Moreover, “Hierarchical EHOP”, a new structural pattern for EHOP was defined which enforces rules between concepts and produces a readable code structure. The main conclusions of this research can be summarized by the following statements. EHOP produces more modular, readable and maintainable code compared to traditional paradigms. Implementing additional concepts and updates to code is seamless using EHOP, yet the lack of development in EHOP’s ecosystem raises frustrating errors and requires the developer to implement libraries that are usually built-in for languages that support traditional paradigms. Functional programming produces faster running code, but EHOP is more memory efficient. Therefore, for applications that interact with users EHOP is the better choice and for applications that only execute code functional programming is more suitable.https://github.com/alibasaran/EHOP-Excel/ The codebase containing the implemented application as well as scripts that were used in programming paradigm analysis.CSE3000 Research ProjectComputer Science and Engineerin
Sequencing Wafer Handler Moves to Improve the Performance of Sequential Cluster Tools
No full textCluster tools are highly integrated machines that can perform a sequence of semiconductor manufacturing processes. The sequence of wafer handler moves affects the total time needed to process a set of wafers. Reducing this time can reduce cycle time, reduce tool utilization, and increase tool capacity. This paper introduces the cluster tool scheduling problem for sequential cluster tools and describes a branch-and-bound algorithm that can find an optimal sequence of wafer handler moves. In addition, we enumerate the set of 1-unit cyclic sequences for two- and three-stage sequential cluster tools. Experimental results show that the tool performance can be improved significantly if the wafer handler follows a cyclic sequence instead of using a dispatching rule
Correction: Governance of social innovation in forestry (Sustainability, (2020) 12, 3, 10.3390/su12031065)
No full text(1) Replacing the email of the fifth author Wilding Maria [email protected] with [email protected] (2) Deleting two sentences in the second paragraph of Section 4. “Results” on page 6. The deleted part reads as follows: In the Spanish case, a group of forest owners started to organize themselves into groups to better fight forest fires as there was no effective public infrastructure available to address this need. This activity is particularly novel as it introduced a type of bargaining system, namely that individuals would engage in the often dangerous activity of fighting a fire on somebody else’s property based on the trust that if the same event occurs their own land, others would reciprocate. (3) Deleting two sentences in Section 4.3 “Austria’s “Nature Park Specialities” Association” on page 7. The deleted part reads as follows: • In the Spanish case, spontaneous self-organisation took place because of a pressing need and this led to further formalisation and institutionalisation. • In the Spanish case, it is the backbone of the entire endeavour as all firefighters are volunteers and funds are used purely for purchasing equipment such as protective clothing, specialized vehicles and the maintenance of these two things. (4) Deleting the Section 4.4 “Forest Fire Volunteer Groups in Spain” in page 8. The deleted part reads as follows: Fighting forest fires is carried out by local forest owners in parts of Catalonia in Spain [47] who organised during the 1990s and formed an association as forest fire defence groups. The need for this was that there was no effective public infrastructure to defend from forest fires. The arrangement is based on trust: Each forest owner helps in combating the wildfire for other forest owners whilst knowing that these will do the same for his/her land. Such cooperation functions best under the condition that the forest owners know each other in person have regular contact and good relationships in the area. Yet, the activity is highly dangerous, and this requires extra personal will and investments. With the time, the group they managed to reach recognition by local policymakers and new legislation was introduced for their legalisation and public support, the Catalan law regulating the “regulació d’Agrupacions de Defensa Forestal” [50]. This regulation provides the wild fire volunteers with equipment such as garments or cars for the activity. Their example led to positive changes in the Catalonian regional regulation in support of this type of organisation. (5) Deleting one sentence in Section 5 “Discussion: Governance of Social Innovation in Forestry” on the paragraph of (iii) Distinct policy features on page 10 i. The deleted part reads as follows: In the Spanish case, it was clearly the new regional regulation that provided an institutional framework whilst simultaneously leading to recognition and some funding possibilities for the Forest Fire Volunteer groups. (6) Replacing word “four” with the word “three” throughout paper related to three examples (case studies). In the abstract, word “four” was replaced by word “three” in the following two sentences: • To answer this question, we first identified three very different cases across Europe that are compatible with the criteria of social innovation. • In the cases considered, it is evident that the sheer determination and voluntary investment of time and effort by key individuals, who were convinced of the value of the idea for the community, provided indispensable impetus to all three social innovations. On page 2, word “four” was replaced by word “three” in the following two sentences: • The foregoing led us to the decision to study three cases of social innovation in three very different rural areas across Europe. • The subsequent results section will draw its findings from a comparison of the three cases by analysing their differences and commonalities before finally discussing their nature from the perspective of their deductively derived criteria for social innovation: community activities, triggers, internal organisation, financing and support. On page 4, word “four” was replaced by word “three” in the following three sentences: • From this pool of eleven cases, we identified the three best suited to our research question and that show the diversity of social innovation across forest activities and across European regions. • All three cases formed cooperative associations with strong involvement from civil society and produced collective benefits within the forest sector, thus featuring prominently governance aspects. • Furthermore, these three cases feature geographically distinct regions in Europe and also different products and activities, illustrating variety of institutional and natural conditions for developing social innovations. On page 6, word “four” was replaced by word “three” in the following sentence: • Moreover, all three cases characterise involvement of several actors and institutions that are supported by associations. Finally, one of them actively involves socially vulnerable groups in their training and skills development programme (UK). On page 10, word “four” was replaced by word “three” in the following three sentences: • In all three cases, being able to secure volunteers to work is one of the most important features. • Volunteer work was especially important during the founding phase in all three cases, and it still has an indispensable role in the UK case. • In particular, we have observed in the three considered cases from the forest sector (i) strong agency, (ii) creative and novel related impacts on their social innovation endeavours [8,9,19,23,25].
