The European Organization for Nuclear Research (CERN) operates the largest particle collider in the world. This particle collider is called the Large Hadron Collider (LHC) and it will undergo a maintenance break sometime in 2017 or 2018. During the break, the particle detectors, which operate around the particle collider, will be serviced and upgraded. Following the improvement in performance of the particle collider, the requirements for the detector electronics will be more demanding. In particular, the high amount of radiation during the operation of the particle collider sets requirements for the electronics that are uncommon in commercial electronics. Electronics that are built to function in the challenging environment of the collider have been designed at CERN. In order to meet the future challenges of data transmission, a GigaBit Transceiver data transmission module and an E-Link data bus have been developed. The next generation of readout electronics is designed to benefit from these technologies. However, the current readout electronics chips are not compatible with these technologies. As a result, in addition to new Gas Electron Multiplier (GEM) detectors and other technology, a new compatible chip is developed to function within the GEMs for the Compact Muon Solenoid (CMS) project. In this thesis, the objective was to study a data transmission interface that will be located on the readout chip between the E-Link bus and the control logic of the chip. The function of the module is to handle data transmission between the chip and the E-Link. In the study, a model of the interface was implemented with the Verilog hardware description language. This process was simulated by using chip design software by Cadence. State machines and operating principles with alternative possibilities for implementation are introduced in the E-Link interface design procedure. The functionality of the designed logic is demonstrated in simulation results, in which the implemented model is proven to be suitable for its task. Finally, suggestions that should be considered for improving the design have been presented.

ABSTRACT: Clinical and complementary analysis are good alternatives to evaluate physiological demand in performance horses. The aim of this study was to assess whether the physical effort variation of the three-day Vaquejada competition (a Brazilian form of bullfighting) reflected in clinical and blood gasometric changes. During the competition eight sprints have been performed on the first day (D1), eight on the second (D2) and three on the last one (D3). Ten horses were evaluated by checking heart and respiratory rates and collecting blood samples for use in portable chemistry analyzer. Through that, it was assessed potential of hydrogen ion (pH), carbon dioxide pressure (pCO2), bicarbonate (HCO3-) and titratable base concentration (cBase). Evaluations were carried with resting of at least twenty hours, before physical activity (D0), as control parameter, and up to thirty minutes after each sprint. Clinical parameters have increased on D1, D2 and D3, when compared to D0, which demonstrated the increased demand for substrate and oxygen to the cells.. Blood gasometric trial showed reductions of all variables, most marked between D1 and D2. It was verified less alteration of all clinical and blood gasometric parameters in D3 against D0. We concluded that the change effort between days of competition influenced the clinical and blood gas parameters, demonstrating appropriate physiological response. The data were presented as mean and standard error of the mean (mean ± SEM) obtained in different days. Normality was confirmed by the Kolmogorov-Sminov test and data were compared by one-way ANOVA, followed by post-test Holm-Sidak (GraphPad Prism 2.6 for Windows, GraphPad Software, San Diego, CA, USA). P≤0.05 was considered as statistically significant.

The Age of Speed:Automobility’s Gender in the 1920s Finland The aim of this study is to analyze the connections between automobility and gender in Finland in the 1920s. In this study it is argued that the 1920s was the significant era in the Finnish history of automobility when many of the long-lasting gendered notions and cultural understandings were constructed. This study combines cultural history of technology with gender analysis. As the previous research on gender and technology has recognized, technology is a significant site of gender negotiations. Both from the cultural historical perspective and a gender perspective it is important to understand both technology and gender as cultural constructions. They were linked together and constructed each other. In other words: technology shapes gender and gender shapes technology. Historians of technology like Nina Lerman, Ruth Oldenziel and Arwen Mohun have argued that both gender and technology are about power: social, cultural, economic and political. In this study automobility means technology that can be analyzed in layers of identity, structures, institutions and representations. The source material consists of various types of historical sources, magazines and journals, advertisements, archival material together with films and literature. In the previous studies of the history of automobility gender has often been neglected. The term “gender” has also quite often been misunderstood. Some studies in the field have only focused on the early female drivers. However, far too little attention has been paid to the question, why automobility was considered as masculine sphere only. This study aims to give new insights to the previous interpretations of the history of automobility. As in various other countries also in Finland, the decade of the 1920s is characterized as a period of “modern times.” It was also the era of the automobiles. Although the number of cars in Finland was still low compared to the other European countries and the USA, in press, films and literature, images of automobiles and new women – and men – on the wheel became as an emblem of a new era. The thesis consists of three main chapters. The first main chapter focuses on the conflicts between drivers and non-drivers. The study shows how in the debate of the automobility “a driver” was constantly referred as a man and “a pedestrian” accordingly a woman, even though in the reality there were as much men and women walking on the streets and the roads. Thus, the public debate constructed and reconstructed the gendered traffic system where men were playing the key role. The second main chapter of the study analyses the automobile clubs and the cultural representations. The chapter answers the question how the concept of a driver was gendered. The Automobile clubs and the organizations of professional drivers were in a significant role in developing the early history of traffic in Finland. The Finnish Automobile Club (Suomen Automobiili Klubi, founded in 1919) was the oldest and the most powerful of all automobile organizations. The Finnish Automobile Club accepted women as members from the very beginning. The membership was strictly limited to the upper class and the very first female members were wives and daughters of the male members. However, Doctor of medicine and surgery 316 Karolina Eskelin (1867-1936) the founding member of the Club was an exception to that convention. The male members of the Finnish Automobile Club attended official international meetings and consulted Finnish authorities in traffic and road questions, whereas, female members joined car trips, picnics and social gatherings arranged by the club. Few young female members of the club drove in races and gross-country-tours. The cultural representations of drivers in the Finnish media in the 1920s both deconstructed and reconstructed the concept of gender. In Finnish press in general, motoring was seen as male dominated area. Men were represented as the experts of the automobility. The drivers’ uniforms and the automobile clubs underlined professionalism and expertise which, thus, got masculine meaning. Women were beautiful accessories in the car ads, but they were also becoming a new consumer group in the market. The representations of the female and the male drivers influenced and shaped actively the understandings of femininity and masculinity. In the third main chapter the analysis focuses on the automobile as an artifact.The automobile was considered as an artifact that primarily belonged to the masculine domain. However, the representations of the automobiles were ambivalent. The automobile was both masculine and feminine depending on the context. The representations of the automobile were also used to construct the discourse of heteronormativity.

It has been commonly thought that standards of beauty are arbitrary cultural conventions that vary between cultures and time. In my thesis I found that it is not so. Instead, I show that attractiveness and preferred traits serve as cues to phenotypic qualities that provide selective benefits for those who choose their mates based on these criteria. In the first study I show that attractive men have a stronger antibody response to the hepatitis b vaccine and higher levels of testosterone than their less attractive peers. Men with low levels of testosterone also tend to have high levels of the stress hormone cortisol, suggesting that their immune responses may have been inhibited by stress hormones. Thus, facial attractiveness may serve as an honest cue of the strength of immune defence in men. In the second study, I show that the attractiveness of the male body is also a cue of better immunity. In addition, I show that adiposity, both in men’s faces and bodies, is a better cue of the strength of immunity and attractiveness than of masculinity. In the third study, I test the preferences of women from 13 countries for facial cues of testosterone and cortisol. I show that there is cross-cultural variation in women’s preference for cues of testosterone and cortisol in male faces. I found a relationship between the health of a nation and women’s preferences for cues of testosterone in the male face and the interaction between preferences for cues of testosterone and cortisol. I show also a relationship between preferences for cues of testosterone and a societal-level measure of parasite stress. Thus, it seems that societal-level ecological factors influence the relative value of traits as revealed by combinations of testosterone and stress hormones. In the fourth study, I show that women’s immune responsiveness (amount of antibodies produced) does not predict facial attractiveness. Instead, plasma cortisol level is negatively associated with attractiveness, indicating that stressed women look less attractive. Fat percentage is curvilinearly associated with facial attractiveness, indicating that being too thin or too fat reduces attractiveness. This study suggests that in contrast to men, facial attractiveness in women does not indicate the strength of immune defence, but is associated with other aspects of long-term health and fertility: circulating levels of the stress hormone cortisol and the percentage of body fat. In the last study I show that the attractiveness of men’s body odor is positively correlated with stress hormone levels, suggesting also that the attractiveness of body odors may signal the phenotypic quality of males to females. However, the attractiveness of men’s body odor was not associated with testosterone levels. My thesis suggests that the standard of beauty is not in the eye of the beholder. Instead, our standard of beauty is hardwired in our brains by genes that are selected by natural selection and also influenced by current environmental conditions.

Tässä työssä tutkitaan sairaalan lääkintätekniikkaa ja kuinka sen toimintaa voitaisiin ohjata prosessijohtamisella. Työssä on tunnistettu sekä määritetty ja kuvattu lääkintätekniikan prosessit, suunniteltu mittausmenetelmät ja annettu prosesseille kehityssuosituksia. Työn merkittävimmät tulokset keskittyvät nykyisten järjestelmien kehittämiseen ja suorituskyvyn mittaamisen haastavuuteen. Tutkimuksen tuloksena havaittiin, että lääkintätekniikan prosessijohtaminen on mahdollista, mutta vaikutukset suorituskykyyn olisivat pienet. Suositukset kehitystoimenpiteisiin keskittyvät paljon tiedon jakamiseen, koska tutkimuksessa teetetyssä kyselyssä ilmeni palveltavien osastojen haluavan paljon tietoa lääkintätekniikalta. Tietoa tullaan jakamaan nykyisen lääkintätekniikan sovelluksen Mequsoftin välityksellä, koska lähestulkoon kaikki olennainen tieto kirjataan jo sinne.

Onnistuneesti suoritettu suorituskyvyn mittaaminen ja johtaminen tuovat kirjallisuuden mukaan organisaatiolle monia hyötyjä. Ohjelmistotyön suorituskyky vaikuttaa ohjelmistoyritysten kannattavuuteen ja ohjelmointiprojektien tuloksellisuuteen. Ohjelmistotyön suorituskyvyn parantamisessa on suurelta osin keskitytty prosessien parantamiseen. Ohjelmistotyön suorituskyvyn taustalla on kuitenkin paljon muitakin tekijöitä kuin prosessi-indikaattorit. Sitoutuneisuus ja motivoituneisuus nähdään yhä tärkeämpinä tekijöinä ohjelmistotyön suorituskyvyn taustalla, joten suorituskyvyn johtamisen tulee huomioida nykyistä paremmin myös henkilöstön näkökulma. Tämän tutkimuksen tavoitteena oli tutkia suorituskyvyn johtamisen viitekehysten, ohjelmistotyön suorituskyvyn taustatekijöiden, motivaation merkityksen ja johtamistyylien analysoinnin avulla, millainen suorituskyvyn mittaus- ja johtamisjärjestelmä (PMS) tukisi ohjelmistotyön suorituskyvyn johtamista huomioiden henkilöstön näkökulman. Tutkimuksessa analysoitiin aiempia aihepiiriä koskevia tutkimuksia ja lisäksi haastateltiin alan yritysasiantuntijoita. Tutkimuksen tuloksena esitettiin tärkeimmät ohjelmistotyön suorituskyvyn taustatekijät, joiden tilan parantamista suorituskyvyn johtamisen tulee mahdollistaa. Näiden havaittiin olevan läheisessä suhteessa henkilöstön motivaatiotekijöihin, joiden sitouttavaa kehittymistä johtamisen tulee myös tukea. Tulokset kiteytettiin suosituksiin koskien johtamista ja mittaristomallia, joita voidaan hyödyntää ohjelmistotyön suorituskyvyn johtamisessa huomioiden henkilöstön näkökulma. Mallissa on kuvattu mitattavat ja johdettavat tekijät yksilö- ja tiimitasolla, esimiestyössä sekä henkilöstövoimavarojen johtamisessa (HRM).

Temperate and temperate x tropical germplasms were introduced into the maize breeding of the Department of Genetics (ESALQ-USP). Twenty populations designated as P-1 to P-20 and a check population were evaluated in a randomized complete block design with two replications at Piracicaba, SP, Brazil. Plots were 2.0 m long, spaced 1.0 m apart, with 10 plants per plot after thinning. The following traits were evaluated: PH, plant height; EH, ear height; TB, tassel branch number; KW, 100 kernels weight; EL, ear length; ED, ear diameter; KR, kernels per row, and RN, number of rows of kernels. The means of the exotic populations showed a variation in performance for all traits. The population means were greater than check means for KW, EL, and KR. Populations P-9, P-10, P-12, and P-13 showed low relative ear placement values (EH/PH index), indicating that these materials could contribute to lower ear placement in local populations. P-1 and P-9 showed a high potential to reduce TB. The phenotypic correlation coefficients among populations were positive for most combinations, except for RN with PH, EH, TB, and KW. Predictions of 19 composite means were obtained for all traits.

Simple reaction time (SRT) in response to visual stimuli can be influenced by many stimulus features. The speed and accuracy with which observers respond to a visual stimulus may be improved by prior knowledge about the stimulus location, which can be obtained by manipulating the spatial probability of the stimulus. However, when higher spatial probability is achieved by holding constant the stimulus location throughout successive trials, the resulting improvement in performance can also be due to local sensory facilitation caused by the recurrent spatial location of a visual target (position priming). The main objective of the present investigation was to quantitatively evaluate the modulation of SRT by the spatial probability structure of a visual stimulus. In two experiments the volunteers had to respond as quickly as possible to the visual target presented on a computer screen by pressing an optic key with the index finger of the dominant hand. Experiment 1 (N = 14) investigated how SRT changed as a function of both the different levels of spatial probability and the subject's explicit knowledge about the precise probability structure of visual stimulation. We found a gradual decrease in SRT with increasing spatial probability of a visual target regardless of the observer's previous knowledge concerning the spatial probability of the stimulus. Error rates, below 2%, were independent of the spatial probability structure of the visual stimulus, suggesting the absence of a speed-accuracy trade-off. Experiment 2 (N = 12) examined whether changes in SRT in response to a spatially recurrent visual target might be accounted for simply by sensory and temporally local facilitation. The findings indicated that the decrease in SRT brought about by a spatially recurrent target was associated with its spatial predictability, and could not be accounted for solely in terms of sensory priming.

Kandidaatintyössä toteutetaan OBD2 (On-Board Diagnostics 2) -lukija ajoneuvon päästöjenhallintajärjestelmän diagnostiikkatiedoille yleiskäyttöisellä mikro-ohjaimella. Lukija tukee tiedonsiirtoprotokollana SAE J1850 VPW protokollaa. Mikro-ohjaimena on Atmel Corporationin AVR ATMega328. Työn tavoitteena on havainnoida vastaantulevia käytännön ongelmia ja haasteita mikro-ohjaimen käytöllä tiedonsiirtoprotokollan toteutukseen, ja verrata toteutettua järjestelmää kaupallisiin OBD2-lukijoihin. Työn johtopäätöksenä havaitaan mikro-ohjaimen suorituskyvyn rajoitteet ja sen tuomat toiminnan epävarmuustekijät. Työssä myös todetaan, että mikro-ohjain soveltuu tiedonsiirtoprotokollan toteutukseen kun rajoitteet otetaan huomioon. Kaupallisiin lukijoihin verrattuna yleiskäyttöiseen mikro-ohjaimeen perustuva toteutettu järjestelmä on kalliimpi ja toiminnoiltaan suppeampi. Mikro-ohjaimeen perustuva järjestelmä on kuitenkin muokattavissa ja laajennettavissa tarvittaessa, jolloin toteutukseen voidaan saada kaupallisista järjestelmistä mahdollisesti puuttuvia ominaisuuksia, kuten valmistajakohtaisia protokollia ja toimintoja, joita ei ole määritelty OBD2:ssa. Yhtenä esimerkkinä tällaisesta toiminnosta voi mainita ajoneuvoissa yleistyvän sähköisen käsijarrun säätöä ohjaavat komennot jarruhuoltoa varten.

Flight safety is one of the most important and frequently discussed issues in aviation. Recent accident inquiries have raised questions as to how the work of flight crews is organized and the extent to which these conditions may have been contributing factors to accidents. Fatigue is based on physiologic limitations, which are reflected in performance deficits. The purpose of the present study was to provide an analysis of the periods of the day in which pilots working for a commercial airline presented major errors. Errors made by 515 captains and 472 copilots were analyzed using data from flight operation quality assurance systems. To analyze the times of day (shifts) during which incidents occurred, we divided the light-dark cycle (24:00) in four periods: morning, afternoon, night, and early morning. The differences of risk during the day were reported as the ratio of morning to afternoon, morning to night and morning to early morning error rates. For the purposes of this research, level 3 events alone were taken into account, since these were the most serious in which company operational limits were exceeded or when established procedures were not followed. According to airline flight schedules, 35% of flights take place in the morning period, 32% in the afternoon, 26% at night, and 7% in the early morning. Data showed that the risk of errors increased by almost 50% in the early morning relative to the morning period (ratio of 1:1.46). For the period of the afternoon, the ratio was 1:1.04 and for the night a ratio of 1:1.05 was found. These results showed that the period of the early morning represented a greater risk of attention problems and fatigue.

Studies have shown that dyslexic children present a deficiency in the temporal processing of auditory stimuli applied in rapid succession. However, discussion continues concerning the way this deficiency can be influenced by temporal variables of auditory processing tests. Therefore, the purpose of the present study was to analyze by auditory temporal processing tests the effect of temporal variables such as interstimulus intervals, stimulus duration and type of task on dyslexic children compared to a control group. Of the 60 children evaluated, 33 were dyslexic (mean age = 10.5 years) and 27 were normal controls (mean age = 10.8 years). Auditory processing tests assess the abilities of discrimination and ordering of stimuli in relation to their duration and frequency. Results showed a significant difference in the average accuracy of control and dyslexic groups considering each variable (interstimulus intervals: 47.9 ± 5.5 vs 37.18 ± 6.0; stimulus duration: 61.4 ± 7.6 vs 50.9 ± 9.0; type of task: 59.9 ± 7.9 vs 46.5 ± 9.0) and the dyslexic group demonstrated significantly lower performance in all situations. Moreover, there was an interactive effect between the group and the duration of stimulus variables for the frequency-pattern tests, with the dyslexic group demonstrating significantly lower results for short durations (53.4 ± 8.2 vs 48.4 ± 11.1), as opposed to no difference in performance for the control group (62.2 ± 7.1 vs 60.6 ± 7.9). These results support the hypothesis that associates dyslexia with auditory temporal processing, identifying the stimulus-duration variable as the only one that unequally influenced the performance of the two groups.

The aim of this study was to test the hypothesis of differences in performance including differences in ST-T wave changes between healthy men and women submitted to an exercise stress test. Two hundred (45.4%) men and 241 (54.6%) women (mean age: 38.7 ± 11.0 years) were submitted to an exercise stress test. Physiologic and electrocardiographic variables were compared by the Student t-test and the chi-square test. To test the hypothesis of differences in ST-segment changes, data were ranked with functional models based on weighted least squares. To evaluate the influence of gender and age on the diagnosis of ST-segment abnormality, a logistic model was adjusted; P < 0.05 was considered to be significant. Rate-pressure product, duration of exercise and estimated functional capacity were higher in men (P < 0.05). Sixteen (6.7%) women and 9 (4.5%) men demonstrated ST-segment upslope ≥0.15 mV or downslope ≥0.10 mV; the difference was not statistically significant. Age increase of one year added 4% to the chance of upsloping of segment ST ≥0.15 mV or downsloping of segment ST ≥0.1 mV (P = 0.03; risk ratio = 1.040, 95% confidence interval (CI) = 1.002-1.080). Heart rate recovery was higher in women (P < 0.05). The chance of women showing an increase of systolic blood pressure ≤30 mmHg was 85% higher (P = 0.01; risk ratio = 1.85, 95%CI = 1.1-3.05). No significant difference in the frequency of ST-T wave changes was observed between men and women. Other differences may be related to different physical conditioning.
